Explanatory Note

NightHawk Biosciences, Inc., and its consolidated subsidiaries (the “Company”, “we” or “us”) is filing this comprehensive Annual Report on Form 10-K for the fiscal years ended December 31, 2022 and 2021 (this “Annual Report”). This Comprehensive Form 10-K contains our audited financial statements for the fiscal year ended December 31, 2022, as well as summarized financial information related to the restatement of the following previously filed periods: (i) our unaudited consolidated financial statements covering the quarterly reporting periods during fiscal year 2022, consisting of June 30, 2022 and September 30, 2022.

​

Restatement Background

​

As previously disclosed, on March 17, 2023, the Audit Committee (the “Audit Committee”) of the Board of Directors of NightHawk Biosciences, Inc. (the “Company”) concluded, after discussion with the Company’s management and BDO USA, LLP (“BDO”), the Company’s independent registered public accounting firm, that the Company’s (i) unaudited consolidated interim financial statements as of and for the period ended June 30, 2022 included in the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2022 and the (ii) unaudited consolidated interim financial statements as of and for the period ended September 30, 2022 included in the Company’s Quarterly Report on Form 10-Q for the quarter ended September 30, 2022 (collectively, the “Specified Financial Statements”), should no longer be relied upon due to errors in such financial statements, and therefore a restatement of these specified financial statements is required. These errors resulted in net loss being overstated but have no effect on the Company’s cash position, pre-tax loss or the Company’s operating expenses and will result in a decrease in the net loss and loss per share for those periods.

​

During the preparation and review of its annual tax provision for the year ended December 31, 2022, it was determined that the Company made certain errors in the manner in which it recognized a deferred tax asset valuation allowance related to the acquisition of Elusys Therapeutics, Inc. (“Elusys”). Under ASC 740 – Income Taxes, the release of an acquirer’s valuation allowance on the acquirer’s (i.e., the Company’s) deferred tax assets in the amount of the acquired Elusys deferred tax liability (“DTL”) should be recorded as an income tax benefit, and be reported as a component of net loss. The DTL was on the balance sheet at June 30, 2022 and September 30, 2022, however the DTL was not and should have been recorded as an income tax benefit on the income statement for the quarter ending June 30, 2022. This error resulted in net loss being overstated by $3.3 million for the three and six months ended June 30, 2022, understated by $0.3 million and overstated by $3.1 million for the three and nine months ended September 30, 2022.

Items Restated in this Form 10-K

This Annual Report reflects changes to the Consolidated Balance Sheets for the periods ended June 30, 2022 and September 30, 2022 and the Consolidated Statements of Income and Comprehensive Loss, Stockholders’ Equity, and Cash Flows for the quarters ended June 30, 2022 and September 30, 2022, and the related notes thereto. Restatement of the summarized consolidated financial information for the quarterly periods are disclosed in Note 17 to the consolidated financial statements.

The Company has not filed, and does not intend to file, amendments to the previously filed Quarterly Reports on Form 10-Q for the quarters ending June 30, 2022 and September 30, 2022. Accordingly, investors should rely only on the financial information and other disclosures regarding the restated periods in this Annual Report or in future filings with the Securities and Exchange Commission (“SEC”) (as applicable), and not on any previously issued or filed reports, earnings releases or similar communications relating to these periods.

In addition, as required by Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), new certifications by the Company’s principal executive officer and principal financial officer are filed herewith as exhibits to this Form 10-K pursuant to Rule 13a-14(a) of the Exchange Act and Section 1350 of Chapter 63 of Title 18 of the United States Code (18 U.S.C. 1350).

See Note 17 to the consolidated financial statements, included in Part II, Item 8 of this Annual Report, for additional information on the restatement and the related consolidated financial statement effects.

Forward-Looking Statements

The forward-looking statements are contained principally in Part I, Item 1. “Business,” Part I, Item 1A. “Risk Factors,” and Part II, Item 7. “Management’s Discussion and Analysis of Financial Condition and Results of Operations,” but are also contained elsewhere in this Annual Report and in some cases you can identify forward-looking statements by terminology such as “may,” “should,” “potential,” “continue,” “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates,” and similar expressions. These statements are based on our current beliefs, expectations, and assumptions and are subject to a number of risks and uncertainties, many of which are difficult to predict and generally beyond our control, that could cause actual results to differ materially from those expressed, projected or implied in or by the forward-looking statements.

You should refer to Item 1A. “Risk Factors” section of this Annual Report for a discussion of important factors that may cause our actual results to differ materially from those expressed or implied by our forward-looking statements. As a result of these factors, we cannot assure you that the forward-looking statements in this Annual Report will prove to be accurate. Furthermore, if our forward-looking statements prove to be inaccurate, the inaccuracy may be material. In light of the significant uncertainties in these forward-looking statements, you should not regard these statements as a representation or warranty by us or any other person that we will achieve our objectives and plans in any specified time frame, or at all. We do not undertake any obligation to update any forward-looking statements. Unless the context requires otherwise, references to “we,” “us,” “our,” and “NightHawk,” refer to Nighthawk Biosciences, Inc. and its subsidiaries.

We are a fully integrated biopharmaceutical company specializing in the end-to-end development, manufacturing, and commercialization of innovative medical countermeasures that combat unmet and emerging biothreats. Our ecosystem is driven by the discovery efforts of our subsidiary, Skunkworx Bio, Inc. (“Skunkworx”), the clinical and commercial biodefense expertise of our subsidiary, Elusys Therapeutics, Inc. (“Elusys”), and the bioanalytical, process development and biomanufacturing capabilities of our subsidiary, Scorpius Biomanufacturing, Inc. (“Scorpius”). The coordination of this ecosystem potentiates the streamlined development and delivery of life-saving medical countermeasures, including our anthrax antitoxin ANTHIM® (obiltoxaximab).

​

The monoclonal antibody ANTHIM® (obiltoxaximab) received FDA approval and orphan drug exclusivity in 2016 for the treatment of inhalational anthrax in combination with antibiotics, and as a prophylaxis when alternative therapies are not available or are not appropriate. Additionally, ANTHIM® was approved in 2020 as the only licensed anthrax antitoxin treatment in the European Union (“EU”) and Canada, and in 2021 in the United Kingdom. Working closely with Biomedical Advanced Research and Development Authority (“BARDA”), the National Institute of Allergy and Infectious Disease (“NIAID”), and the Department of Defense (“DoD”), Elusys has successfully advanced ANTHIM® to the commercial stage and provides the therapeutic for inclusion in both the US Strategic National Stockpile (“SNS”) and the Public Health Agency of Canada Office of Emergency Response Services Depot.

​

Scorpius pairs cGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support cell- and gene-based therapies as well as large molecule biologics. Scorpius decreases our dependence on third-party contract research and development biomanufacturing organizations (CDMOs) for the manufacture of ANTHIM® (obiltoxaximab) and other assets and allows us to be opportunistic in offering excess capacity to third parties as a fee-for-service model. Our lead facility commenced operations in October 2022 in San Antonio, Texas. Planning and development efforts are underway on a potential commercial manufacturing facility to be built in Manhattan, Kansas in the coming years.

OUR BIOMANUFACTURING, PROCESS DEVELOPMENT, AND BIOMANUFACTURING CAPABILITIES: SCORPIUS BIOMANUFACTURING, INC.

Manufacturing

Scorpius (formerly known as Scorpion Biological Services, Inc.) provides process development and biomanufacturing services to support our biotherapeutics and discovery pipeline. Scorpius also supports the biomanufacturing needs of third parties who use its excess biomanufacturing capacity as a fee-for-service model. Scorpius couples cGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support cell- and gene-based therapies as well as large molecule biologics using American-made equipment, reagents, and materials. The subsidiary expects to decrease our dependence on third-party CDMOs for the manufacture of ANTHIM®, assuming receipt of necessary regulatory approvals, and other assets as well as allow us to be opportunistic in offering excess capacity to third parties on a fee-for-service model. We are in the process of completing the technology transfer of ANTHIM® to Scorpius for future production. We anticipate the prioritization of Scorpius on American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make us competitive for U.S. government contracts and biodefense assets. We anticipate this will successfully support our expansion within the growing CDMO market.

​

We commenced operations of the leased San Antonio facility in September 2022 and are planning to begin development efforts on a commercial manufacturing facility expected to be built in Manhattan, Kansas in the coming years. We have historically relied on third-party manufacturers to produce and store our product candidates for clinical use and currently do not operate our own manufacturing facilities. In order to promote efficiency and reduce our reliance on third-party vendors, we have enhanced our in-house development of bioanalytic, process development and manufacturing capabilities and offer such services to third parties for fees. We expect to fill production capacity by transitioning our outsourced manufacturing and development in-house following validation activities and then contracting with external customers. However, there can be no assurance that we will be successful in these new operations.

​

We intend to meet our financing needs for the operations of the facility through multiple alternatives, including, but not limited to, cash on hand, grant funding and incentives, additional equity financings, debt financings and/or funding from partnerships or collaborations, and potential revenue, if any, from our planned development and manufacturing facility.

​

In April 2022, we announced a planned partnership of Scorpius, a private developer, the State of Kansas, and local and university affiliates to support the development of a 500,000+ square foot biodefense-focused large molecule and biologics biomanufacturing phased, multi-building facility in Manhattan, Kansas. Scorpius intends to utilize the new facility for large molecule and biologics manufacturing, with a particular focus on biodefense. In addition to servicing our own pipeline, Scorpius plans to operate and utilize the facility as a full-service CDMO to provide third-party manufacturing services on a fee-for-service basis. Scorpius and the developer have applied for over $300 million in funding, incentives, and tax relief to support the development of the facility. In April 2022, the City Commission of Manhattan, Kansas, passed a resolution supporting the proposed commercial manufacturing facility and its intent to offer an Economic Development Package that includes the issuance of approximately $567 million in industrial revenue bonds with proposed sales tax exemptions, an anticipated 10-year 100% property tax abatement plan, and an expected $8 million forgivable loan that will be tied to the realized capital investment and employee jobs, wages, and benefits. The Economic Development Package is conditioned upon successful negotiation and future action by the City Commission and upon Scorpius meeting certain negotiated performance and hiring goals.

​

We plan to manufacture CGMP pharmaceutical-grade products for our customers in our San Antonio facility. To date Scorpius has three customers for which it has not recognized any revenue. The deposits from these customer are in deferred revenue and will be converted to revenue once we meet our performance obligations for these contracts. The process for manufacturing generally uses commercially available raw materials from multiple suppliers, and in some instances, from a single source supplier. We rely on third parties to supply most of the necessary raw materials and supplies for the products

we manufacture on behalf of our customers and our inability to obtain such raw materials or supplies may adversely impact our business, financial condition, and results of operations. See “Risk Factors—Risks Related to Our Business” for additional discussion of raw materials supplied by third party vendors for the products we manufacture for our customers.

​

Biodefense

​

In 2022, we acquired ANTHIM® (obiltoxaximab) when we consummated the transaction contemplated by the Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) with our wholly owned subsidiary (“Merger Sub”), Elusys and Fortis Advisors LLC, pursuant to which we acquired Elusys through the merger (the “Merger”) of Merger Sub with Elusys. ANTHIM® is a monoclonal antibody antitoxin for anthrax. Our biodefense discovery and preclinical efforts remain focused on identifying novel assets to combat emerging biological threats. To date, all revenue that Elusys received for the sale of ANTHIM®, subsequent to our acquisition of Elusys, has been $6.0 million in procurement contracts to provide ANTHIM® (obiltoxaximab) to the Canada Office of Emergency Response Services Depot.

​

Anthrax

​

Anthrax is a disease caused by Bacillus anthracis. While it is primarily a disease of animals, cases of anthrax in humans occur through contact with infected animals or animal products or through intentional spread of Bacillus anthracis (“B. Anthracis”) spores as a biowarfare or bioterrorism agent. Due to its virulence, high mortality, and ease to produce and disseminate, B. anthracis is considered a potent and dangerous “Category A” biowarfare or bioterrorism agent. Inhalational anthrax (i.e., when infection occurs via inhalation of bacterial spores) is particularly deadly. Untreated, the mortality rate is 97% and remains high (~50%) for individuals that are not administered aggressive antimicrobial treatment at the earliest stages of the disease. Once the disease has progressed to the fulminant stage, accumulated anthrax toxins drive progression of disease despite antibiotic therapy, resulting in death. In addition, antibiotics may be ineffective in infections with multi-drug-resistant B. anthracis or contraindicated in certain patient populations.) Bacillus anthracis is recognized by Public Health Emergency Medical Countermeasures Enterprise as a high-priority threat.

​

About ANTHIM® (obiltoxaximab)

​

ANTHIM® (obiltoxaximab) is a monoclonal antibody that binds the protective antigen (PA) component of the anthrax. Obiltoxaximab’s toxin neutralizing activity prevents entry of anthrax toxin into susceptible cells, avoiding further spread of the toxin throughout the body and the ensuing tissue damage that leads to death. ANTHIM® (obiltoxaximab) is supplied as single-dose vials for IV infusion.

​

The development of ANTHIM® (obiltoxaximab) was supported by ~$250M USD in non-dilutive development contracts from the National Institutes of Health (“NIH”), Department of Defense (“DoD”), and Biomedical Advanced Research and Development Authority “(“BARDA”) to Elusys. To date, Elusys has received ~$151M USD and ~$6M USD in procurement contracts to provide ANTHIM® (obiltoxaximab) to the U.S. SNS and the Public Health Agency of Canada Office of Emergency Response Services Depot. NightHawk Biosciences acquired Elusys in April 2022 and is committed to expanding domestic and international sales of ANTHIM® (obiltoxaximab).

​

ANTHIM® (obiltoxaximab) was approved in the U.S. in 2016 in adults and pediatric patients for the treatment of inhalational anthrax in combination with appropriate antibacterial drugs and for prophylaxis of inhalational anthrax when alternative therapies are not appropriate or available. Furthermore, it was licensed as ANTHIM® (obiltoxaximab) in Canada in 2020, and as NYXTHRACIS® (formerly Obiltoxaximab SFL) in the EU in 2020 in adults and pediatric patients for the treatment of inhalational anthrax in combination with appropriate antibacterial drugs and for the post-exposure prophylaxis of inhalational anthrax when alternative therapies are not appropriate or available. ANTHIM® (obiltoxaximab) should only be used for prophylaxis when its benefit for prevention of inhalational anthrax outweighs the risk of hypersensitivity and anaphylaxis. The effectiveness of ANTHIM® (obiltoxaximab) is based solely on efficacy studies in animal models of inhalational anthrax. There have been no studies of the safety or pharmacokinetics (PK) of ANTHIM® (obiltoxaximab) in the pediatric population. Dosing in pediatric patients was derived using a population PK approach. ANTHIM® (obiltoxaximab) does not have direct antibacterial activity. As such, ANTHIM® (obiltoxaximab) should be used in combination with appropriate antibacterial drugs. ANTHIM® (obiltoxaximab) is not expected to cross the blood-brain barrier and does not prevent or treat meningitis.

Acquisition of Elusys

​

On April 18, 2022, we closed the Merger contemplated by the Merger Agreement (the “Closing”). Pursuant to the Merger Agreement, as merger consideration (“Merger Consideration”) we paid at the Closing a cash upfront payment of $3,000,000 to certain of the equity holders of Elusys (the “Sellers”) and assumed and contributed $867,646 to the payment of 50% of certain Elusys lease termination and employee severance payments. We have also paid to the Sellers (i) $2,000,000 and (ii) agreed to pay earn out payments for a period of 12 years from the date of Closing equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the Closing Date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded or entered into during the first nine years after the Closing Date.

​

In addition, Elusys shareholders’ are to receive an additional payment of approximately $6.0 million, net from the fulfillment of an existing U.S. Government contract which we have agreed to fulfill the future obligations of Elusys under such contract and pass through and distribute to the Sellers the revenue that is received under such contract minus the costs associated with such fulfillment obligations, subject to certain adjustments to the Merger Consideration specified in the Merger Agreement, including income taxes payable with respect to such payments. The Merger Agreement further provides that eighty percent of any amounts paid to and received by Elusys after the Closing and prior to June 30, 2023 with respect to the sale of 1,500 pre-filled vials of ANTHIM® shall be paid to the Sellers, subject to certain adjustments specified in the Merger Agreement. We also agreed to use commercially reasonable efforts to maintain, finance, operate and promote ANTHIM® and maintain the existing government contract and to continue to operate the Elusys business so as to allow the Sellers to receive the Merger Consideration.

​

The Merger Agreement contains customary representations, warranties and covenants of us, Elusys and the Merger Sub. Subject to certain customary limitations, the Sellers have agreed to indemnify us and our officers and directors against certain losses related to, among other things, breaches of Elusys’ representations and warranties, certain specified liabilities and the failure to perform covenants or obligations under the Merger Agreement.

Biothreat Advisory Board

​

In August 2021, we announced the formation of our Biothreat Advisory Board to support the development of our biosecurity/biodefense initiatives. The advisory board includes Greg Burel, David Lasseter, Former Deputy Asst. Sec. of Defense for Countering Weapons of Mass Destruction, Andrew Webber, Former Asst. Sec. of Defense for Nuclear, Chemical & Biological Defense Programs, Jack Kingston, Former US Representative, Secretariat of the Alliance for Biosecurity (current), Gregor Koblentz, PhD, Professor of Biodefense at George Mason University, Expert on Chemical and Biological Weapons, and Former US Senator (AR) Mark Pryor. This panel was assembled to provide ongoing guidance on the development and commercialization of our biodefense assets and platforms.

​

RapidVax®: Preclinical Stage

Development Programs

Our biodefense efforts remain focused on identifying, manufacturing, and commercializing novel assets to combat emerging and existing biological threats through in-house discovery as well as external partnership and in-licensing opportunities such as Lytic Solutions, LLC.

​

In November 2018, we formed the discovery subsidiary Skunkworx (formerly known as Delphi Therapeutics, Inc.) to support in-house nomination of biologics for preclinical and clinical development. Our approach utilizes “Pocket Biologics” derived from diverse proprietary antibody and small protein libraries to identify and differentiate

Table of Contents

pharmacologically active “HotSpot” sites on proteins relevant to disease. Coupled with the integration of computational and bioinformatic analysis, the goal is to “improve” candidate selection and accelerate validation of innovative therapeutics and biodefense assets from discovery into preclinical development.

​

Skunkworx is designing RapidVax® as a flexible “plug-and-play” vaccine platform designed to leverage our vast experience developing gp96-based vaccines and couples the immune-activating properties of heat shock protein gp96 and the T-cell co-stimulator OX40L with a flexible antigen expression system to promote antigen-specific T-cell activation, the generation of long-lasting memory cells, and neutralizing antibody production via the interaction of T follicular helper cells with B cells. RapidVax is designed to utilize a common unprogrammed vaccine base that can be manufactured in bulk, stockpiled, and rapidly customized upon identification of a biological threat to enable an accelerated time to clinic and to harness shared development, clinical safety, and manufacturing synergies.

​

Oncology

​

Prior to 2022, our focus was on the development of our oncology product candidates. More specifically, we were evaluating the potential of the gp96 platform immunotherapy HS-110 (viagenpumatucel-L) in patients with advanced non-small cell lung cancer (“NSCLC”) and completed the enrollment of our Phase 2 trial evaluating the safety and efficacy of HS-110 in combination with either nivolumab (Opdivo®), a Bristol-Myers Squibb anti-PD 1 checkpoint inhibitor, or Merck’s anti-PD1 checkpoint inhibitor, pembrolizumab (KEYTRUDA®), for the treatment of patients with advanced NSCLC. In addition, we completed an open-label, single arm, Phase 1 clinical trial assessing safety and tolerability of PTX-35, a monoclonal antibody which was part of our TNF receptor superfamily member 25 (TNFRSF25) platform, in patients with advanced solid tumors refractory to, or ineligible for, or who refuse available standard of care.

​

In our third quarter 2022 10-Q, we deprioritized our oncology program and the activities of our Heat Biologics I, Inc. and Pelican Therapeutics, Inc. (“Pelican”) subsidiaries to streamline operations to support the discovery, development, and commercialization of innovative medical countermeasures. In January 2023, we terminated all of our license agreements with the University of Miami, including all agreements associated with the gp96 and TNFRSF25 platforms. We are not pursuing further development of the gp96 based HS-110 (viagenpumatucel-L) and RapidVax programs.

​

Terminated License Agreements with University of Miami

From 2008 through 2020, we entered into the following eight (8) license agreements with the University of Miami, all of which notice of termination was provided by us to the University of Miami in January 2023, pursuant to which we or one of our subsidiaries was granted an exclusive, worldwide right to make, use or sell licensed materials based upon the patent-related rights set forth in the license agreements. Under the Agreements set forth in clauses (i)-(v) below, the licensees obtained exclusive rights to different patent families each directed to therapeutic compositions and methods related to targeting gp96.

​

Strategy

Our objective is to become a market leader in the development of innovative medical countermeasures, prioritizing American-made equipment, reagents, materials, and in-house biomanufacturing to streamline the commercialization and delivery of novel biodefense biologics to the U.S. and allied partners. We believe our integrated end-to-end ecosystem provides a strategic advantage by reducing dependency on external third-parties and accelerating our development programs.

We consider expanded U.S. and international sales of our monoclonal antibody anthrax antitoxin ANTHIM® (obiltoxaximab) a driver of future company growth. To date, Elusys has received ~$151M USD and ~$6M USD in procurement contracts to provide ANTHIM® (obiltoxaximab) to the U.S. SNS and the Public Health Agency of Canada Office of Emergency Response Services Depot, respectively. We are actively engaging with new and existing government programs and considering potential investments with business partners to create and expand ANTHIM® (obiltoxaximab) deliveries.

We believe there is a growing market need and deficient availability for large molecule biomanufacturing. Scorpius is expected to decrease our dependence on third-party CDMOs for the manufacture of ANTHIM® (obiltoxaximab) and other assets, and allows us to be opportunistic in offering excess capacity to third parties as a fee-for-service model to fill this market gap. Additionally, we anticipate Scorpius prioritization of American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make the organization competitive for U.S. government contracts and biodefense assets.

​

The key elements of our strategy are:

​

| ● | Establish a fully integrated biopharmaceutical company specializing in end-to-end development and delivery of medical countermeasures and specialty immune-stimulating products: The coordinated efforts of our subsidiaries Skunkworx, Elusys, and Scorpius form a drug development ecosystem designed to fuel innovation, from discovery to commercialization, with minimal reliance on external vendors. This capability offers the potential to translate our discoveries into therapeutics with increased efficiency and quality and without compromising our agility to pursue new innovations.

| ● | Maximize commercial opportunities for ANTHIM® (obiltoxaximab): We believe that ANTHIM® (obiltoxaximab) will continue to be a critical biodefense asset for stockpiling by the U.S. SNS and Public Health

10

Table of Contents

|  | Agency of Canada Office of Emergency Response Services Depot. We intend to be opportunistic in seeking strategic partnerships that maximize the economic potential of this asset and are in the process of completing the technology transfer to Scorpius for future biomanufacturing.

| ● | Maximize commercial opportunities for Scorpius Biomanufacturing, Inc: We launched Scorpius in October 2022 as a CDMO focused on developing bioanalytic, process development, and biomanufacturing capabilities to support our clinical and commercial pipeline. We are opportunistic in offering excess biomanufacturing capacity to third parties as a fee-for-service model and believe our prioritization of American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make the organization competitive for U.S. government contracts and biodefense assets.

| ● | Develop and obtain regulatory approval for our product candidates: Our biodefense efforts remain focused on identifying, manufacturing, and commercializing novel assets to combat unmet and emerging biological threats through in-house discovery, external partnership, and in-licensing opportunities. We anticipate future announcements related to ongoing discovery and development efforts as these programs progress.

| ● | Enhance our partnering efforts: We are continually exploring partnerships for licensing and other collaborative relationships and remain opportunistic in seeking strategic partnerships that maximize our economic potential and align with our objective to become a market leader in the development and commercialization of innovative medical countermeasures.

| ● | Further expand our broad patent portfolio: We have made a significant investment in the development of our patent portfolio to protect our technologies and programs, and we intend to continue to expand our portfolio. Our Elusys subsidiary owns or exclusively licenses a patent estate that covers our ANTHIM® product. We are also developing a patent estate for various new pre-clinical biodefense-related technologies developed by NightHawk or our Skunkworx subsidiary. We also maintain some legacy patent assets relating to gp96 and TNFRSF25 that are owned or co-owned by us and Pelican.

| ● | Manage our business with efficiency and discipline: We believe we have efficiently utilized our capital and human resources to develop and acquire our product candidates and programs and create a broad intellectual property portfolio. These resources form our drug development ecosystem. We use project management techniques to assist us in making disciplined strategic program decisions and to attempt to limit the risk profile of our product pipeline.

| ● | Obtain additional non-dilutive grant funding: To develop our technologies and assets more fully, we continually seek and access external sources of grant funding on our own behalf and in conjunction with our external partners to support the development of our pipeline.

Intellectual Property

Our goal is to obtain, maintain and enforce patent protection for our products, formulations, processes, methods and other proprietary technologies; preserve our trade secrets and exclusive rights in our unique biological materials; and operate without infringing on the proprietary rights of other parties, both in the United States and in other countries. Our policy is to actively seek to obtain, where appropriate, the strongest intellectual property protection possible for our current product candidates and any future product candidates and our subsidiaries’ proprietary information and proprietary technology through a combination of contractual arrangements and patents, both in the United States and abroad. However, even patent protection may not always afford us with complete protection against competitors who seek to circumvent our patents. See “Risk Factors – Risks Related to Intellectual Property.”

We will continue to depend upon the skills, knowledge and experience of our scientific and technical personnel, as well as that of our advisors, consultants and other contractors, none of which is patentable. To help protect our proprietary know-how, which is not patentable, and for inventions for which patents may be difficult to enforce, we currently rely and will in the future rely on trade secret protection and confidentiality agreements to protect our interests. To this end, we require all of our employees, consultants, advisors and other contractors to enter into confidentiality agreements that

11

Table of Contents

prohibit the disclosure of confidential information and, where applicable, require disclosure and assignment to us of the ideas, developments, discoveries and inventions important to our business.

Elusys Intellectual Property

Elusys has an exclusive, fully paid up, worldwide patent license, dated June 30, 2003, from the Board of Regents of the University of Texas which grants Elusys the right to use for the manufacture, offer and sale of antibodies that bind immunologically to anthrax antigens under the patent rights held by the University of Texas under the U.S. patent application entitled “Neutralization of the Anthrax Toxin”, serial number 10/288,269 filed on November 5, 2001 (and subsequently issued by the U.S. Patent and Trademark Office on November 4, 2008, serial number 7,446,182) and the U.S. patent application entitled "Antibodies With Increased Affinities For Anthrax Antigens", serial number 10/620,049 filed on July 15, 2003 (and subsequently issued by the U.S. Patent and Trademark Office on March 8, 2011, serial number 7,902,344). The term of agreement continues until all patent rights have expired, unless terminated automatically due to bankruptcy or insolvency of Elusys or by mutual written agreement. ANTHIM® is covered by 5 US patents which are owned by Elusys or exclusively licensed from the Board of Regents of the University of Texas.

Elusys is the assignee of the U.S. patent application entitled “Antibodies that bind B. anthracis exotoxin, formulations thereof, and methods of use”, serial number 11/904,882 filed on September 28, 2007 (and subsequently issued by the U.S. Patent and Trademark Office on January 10, 2012, serial number 8,093,360) and the U.S. patent application entitled “Methods of preventing or treating anthrax using anti-anthrax antibodies”, serial number 13/076,082 filed on March 30, 2011 (and subsequently issued by the U.S. Patent and Trademark Office on December 31, 2013, serial number 8,617,548).

Emerging and Legacy Intellectual Property

​

NightHawk and Skunkworx hold 5 non-provisional, international (PCT) applications and approximately 10 U.S. provisional applications which covering emerging, pre-clinical biodefense-related technologies, including antibody-based assets related to the “Pocket Biologics” concepts. We also own approximately 30 patents and 30 patent applications, in the U.S., Europe, China, Japan, and other countries, which cover historical gp96 assets. Pelican owns about 20 patents and 20 patent applications, in the U.S., Europe, China, Japan, and other countries, which cover historical TNFRSF25 assets, including coverage of PTX35.

License Agreement with Shattuck Labs

In June 2016, we entered into an exclusive license agreement with Shattuck Labs, Inc. (“Shattuck”) pursuant to which we licensed to Shattuck certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us. Shattuck paid us an initial license fee of $50,000 and is obligated to pay us fees upon its receipt of sublicensing income, achievement of certain milestones and royalties upon sales of commercial products. The technology that was out-licensed to Shattuck is in the early stages of development and there is a low likelihood of success for any technology at such stage, and there can be no assurance that any products will be developed by Shattuck or that we will derive any revenue from Shattuck. In February 2023, we were notified by Shattuck that a milestone was met and we received an additional $100,000 in milestone payments.

External Manufacturing

We have historically relied on third-party manufacturers to produce and store our product candidates for clinical use and currently do not operate our own manufacturing facilities. In order to promote efficiency and reduce our reliance on third-party vendors, we have enhanced our in-house development of bioanalytic, process development and manufacturing capabilities and offer such services to third parties for fees. We have entered into a lease for a 20,144 square foot facility in San Antonio, TX to conduct such services. Our expansion in Texas is part of a company-wide-growth strategy to enhance efficiency and decrease our dependence on third-party vendors as we advance our commercial pipeline. Operations at the facility commenced in October 2022, and we expect to fill production capacity by transitioning our outsourced manufacturing and development in-house immediately, followed by contracting with external customers. However, there can be no assurance that we will be successful in these new operations.

ANTHIM® (obiltoxaximab) is a best-in-class monoclonal antibody antitoxin for anthrax. ANTHIM® (obiltoxaximab) received FDA approval and orphan drug exclusivity in 2016 for the treatment of inhalational anthrax, in combination with antibiotics, and as a prophylaxis when alternative therapies are not available or are not appropriate. ANTHIM® (obiltoxaximab) was also approved in 2020 and 2021 as the only licensed anthrax anti-toxin treatment in the EU, UK, and Canada. ANTHIM® (obiltoxaximab) is being manufactured by an external vendor, Lonza Sales AG (“Lonza”) and we are in the process of completing the tech transfer of this asset to Scorpius for future production. In 2015, Elusys entered into a bulk ordering agreement with Lonza for the commercial production of ANTHIM®. Under the agreement Lonza will manufacture ANTHIM® pursuant to purchase orders issued in accordance with forecasts that we provide. We will purchase ANTHIM® that meets agreed specifications in batches, with the price per batch varying according to the total number of batches ordered for serial production in a single manufacturing campaign. Once we agree to a schedule of services and pricing terms, we are obligated to purchase a minimum number of batches which may be reduced under certain circumstances. On March 31, 2022, we became obligated to purchase batches of ANTHIM® from Lonza. We may be obligated to pay certain fees to Lonza upon cancellation of purchase orders within a certain specified period of time prior to projected commencement of the applicable batch.

Competition

The pharmaceutical, biologics and diagnostic industry is highly competitive and characterized by several established large companies, mid-sized companies, as well as smaller companies like ours. If our competitors market products that are less expensive, safer, or more effective than any future products developed from our product candidates, or that reach the market before our approved product candidates, we may not achieve commercial success. Technological developments in our field of research and development occur at a rapid rate and we expect competition to intensify as advances in this field are made. We will be required to continue to devote substantial resources and efforts to our research and development activities. If we fail to stay at the forefront of technological change, we may be unable to compete effectively.

Biodefense Competition

We anticipate our most significant competitor for ANTHIM® (obiltoxaximab) will be Emergent BioSolutions, Inc. (“Emergent”). Emergent is the provider of the anthrax antitoxin raxibacumab. Raxibacumab received FDA approval on December 14, 2012, while ANTHIM® (obiltoxaximab) received FDA approval on March 18, 2016. ANTHIM® (obiltoxaximab) and raxibacumab both inhibit the binding of anthrax toxin PA to its cellular receptors, preventing the intracellular entry of the anthrax lethal factor and edema factor, the enzymatic toxin components responsible for the pathogenic effects of anthrax toxin. Package inserts indicate that ANTHIM® (obiltoxaximab) has an affinity equilibrium dissociation constant (Kd) of 0.33 nM compared to 2.78 nM for raxibacumab, and a potentially longer shelf life of 7 years compared to 5 years for raxibacumab. ANTHIM® (obiltoxaximab) and raxibacumab have both been supplied to the CDC’s strategic national stockpile. We are fulfilling a delivery order for the U.S. SNS this year and anticipate based on previous delivery orders and option agreements that ANTHIM® (obiltoxaximab) will continue to fulfill delivery orders as part of the Office of the Assistant Secretary for Preparedness & Response’s (ASPR) objective to diversify and acquire products with a longer shelf-life.

Internationally, ANTHIM® (obiltoxaximab) was approved as the only licensed anthrax antitoxin treatment in the EU and Canada in 2020 and in the UK in 2021. In Canada, the approval of ANTHIM® (obiltoxaximab) blocks future purchases of raxibacumab without Canadian Extraordinary-Use New Drug (EUND) approval. Furthermore, we completed delivery of an initial order of ANTHIM® (obiltoxaximab) to the Public Health Agency of Canada Office of Emergency Response Services Depot in 2022 and anticipate discission of future orders. Similarly, in the EU, orphan drug exclusivity (10 year) at the time of approval provides an advantage to ANTHIM® (obiltoxaximab) as we seek to support HERA’s (the European Health Emergency Preparedness and Response Authority) Chemical, Biological, Radiological and Nuclear (CBRN) stockpile initiatives in France, Finland, and Poland. We believe these approvals position ANTHIM® (obiltoxaximab) for increasing biosecurity preparedness in commercially approved ex-U.S. ally territories and we will be opportunistic in seeking strategic partnerships that maximize economic potential of this asset.

Contract Development Biomanufacturing Organization (CDMO) Competition

We formed Scorpius to develop bioanalytic, process development, and biomanufacturing capabilities for our clinical and commercial pipeline as well as to offer excess biomanufacturing capacity to third parties as a fee-for-service CDMO model. Scorpius is focused on cell- and gene-based therapies as well as large molecule biologics and provides a broad array of services prioritizing American-made equipment, reagents, and materials when possible. Scorpius pairs cGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support the advancement of clinical and commercial programs.

​

We anticipate providing competition to established biomanufacturers including Lonza Group, Ltd and WuXi AppTec as well as recently announced biomanufacturing efforts from ThermoFisher Scientific, Inc. The COVID-19 pandemic revealed a critical shortage in U.S. biomanufacturing capacity. Historically, therapies could often take ~10 years to commercialize. However, with the implementation of Emergency Use Authorization, complex, effective vaccines can now advance through pipelines at record speed, contributing to new expectations for time to market, cost reduction, regulatory compliance, and good manufacturing performance. Considering the global cell and gene therapy clinical trials market size was valued at $9.2 billion in 2020 and is expected to expand at a compound annual growth rate (CAGR) of 22.3% from 2021 to 2028 per Grand View Research, we anticipate that a shortage of industry capacity may minimize the risk of direct competition. Additionally, we anticipate Scorpius prioritization of American-made equipment, reagents, and materials paired with domestic sourcing of biomanufacturing expertise will make the organization competitive for U.S. government contracts and biodefense assets. We formed the subsidiary Scorpius to focus on developing bioanalytic, process development and biomanufacturing capability to support our biotherapeutics and discovery pipeline. We plan to offer excess biomanufacturing capacity to third parties as a fee-for-service CDMO model. Scorpius is focused on cell- and gene-based therapies and large molecule biologics. We provide a broad array of biologics manufacturing, analytical and R&D services, offering services using American-made equipment, reagents, and materials. Scorpius couples cGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support the advancement of our development and commercial programs.

Government Regulation

FDA Approval Process

In the United States, pharmaceutical products are subject to extensive regulation by the FDA. The Federal Food, Drug, and Cosmetic Act, (the “FDC Act”), and other federal and state statutes and regulations, govern, among other things, the research, development, testing, manufacture, storage, recordkeeping, approval, labeling, promotion and marketing, distribution, post-approval monitoring and reporting, sampling, and import and export of pharmaceutical products. Biological products used for the prevention, treatment, or cure of a disease or condition of a human being are subject to regulation under the FDC Act, except the section of the FDC Act that governs the approval of new drug applications, or NDAs. Biological products are approved for marketing under provisions of the Public Health Service Act, or PHSA, via a Biologics License Application, or BLA. However, the application process and requirements for approval of BLAs are very similar to those for NDAs, and biologics are associated with similar approval risks and costs as drugs. Failure to comply with applicable U.S. requirements may subject a company to a variety of administrative or judicial sanctions, such as FDA refusal to approve pending NDAs or BLAs, warning or untitled letters, product recalls, product seizures, total or partial suspension of production or distribution, injunctions, fines, civil penalties, and criminal prosecution.

Pharmaceutical product development for a new product or certain changes to an approved product in the U.S. typically involves preclinical laboratory and animal tests, the submission to the FDA of an investigational new drug application, or IND, which must become effective before clinical testing may commence, and adequate and well-controlled clinical trials to establish the safety and effectiveness of the drug for each indication for which FDA approval is sought. Satisfaction of FDA pre-market approval requirements typically takes many years and the actual time required may vary substantially based upon the type, complexity, and novelty of the product or disease.

Preclinical tests include laboratory evaluation of product chemistry, formulation, and toxicity, as well as animal trials to assess the characteristics and potential safety and efficacy of the product. The conduct of the preclinical tests must comply with federal regulations and requirements, including good laboratory practices. The results of preclinical testing are

14

Table of Contents

submitted to the FDA as part of an IND along with other information, including information about product chemistry, manufacturing and controls, and a proposed clinical trial protocol. Long term preclinical tests, such as animal tests of reproductive toxicity and carcinogenicity, may continue after the IND is submitted.

A 30 day waiting period after the submission of each IND is required prior to the commencement of clinical testing in humans. If the FDA has neither commented on nor questioned the IND within this 30 day period, the clinical trial proposed in the IND may begin.

Clinical trials involve the administration of the investigational new drug or biologic to healthy volunteers or patients under the supervision of a qualified investigator. Clinical trials must be conducted: (1) in compliance with federal regulations; (2) in compliance with good clinical practice, or GCP, an international standard meant to protect the rights and health of patients and to define the roles of clinical trial sponsors, administrators, and monitors; as well as (3) under protocols detailing the objectives of the trial, the parameters to be used in monitoring safety, and the effectiveness criteria to be evaluated. Each protocol involving testing on U.S. patients and subsequent protocol amendments must be submitted to the FDA as part of the IND.

The FDA may order the temporary or permanent discontinuation of a clinical trial at any time, or impose other sanctions, if it believes that the clinical trial either is not being conducted in accordance with FDA requirements or presents an unacceptable risk to the clinical trial patients. The study protocol and informed consent information for patients in clinical trials must also be submitted to an institutional review board, or IRB, for approval. An IRB may also require the clinical trial at the site to be halted, either temporarily or permanently, for failure to comply with the IRB’s requirements, or may impose other conditions.

Clinical trials to support NDAs or BLAs for marketing approval are typically conducted in three sequential phases, but the phases may overlap. In Phase 1, the initial introduction of the drug or biologic into healthy human subjects or patients, the product is tested to assess metabolism, pharmacokinetics, pharmacological actions, side effects associated with increasing doses, and, if possible, early evidence on effectiveness. Phase 2 usually involves trials in a limited patient population to evaluate the effectiveness of the drug or biologic for a particular indication, dosage tolerance, and optimum dosage, and to identify common adverse effects and safety risks. If a compound demonstrates evidence of effectiveness and an acceptable safety profile in Phase 2 evaluations, Phase 3 trials are undertaken to obtain the additional information about clinical efficacy and safety in a larger number of patients, typically at geographically dispersed clinical trial sites, to permit the FDA to evaluate the overall benefit-risk relationship of the drug or biologic and to provide adequate information for the labeling of the product. In most cases, the FDA requires two adequate and well-controlled Phase 3 clinical trials to demonstrate the efficacy of the drug or biologic. A single Phase 3 trial with other confirmatory evidence may be sufficient in rare instances where the study is a large multicenter trial demonstrating internal consistency and a statistically very persuasive finding of a clinically meaningful effect on mortality, irreversible morbidity or prevention of a disease with a potentially serious outcome and confirmation of the result in a second trial would be practically or ethically impossible.

After completion of the required clinical testing, an NDA or BLA is prepared and submitted to the FDA. FDA approval of the NDA or BLA is required before marketing of the product may begin in the United States. The NDA or BLA must include the results of all preclinical, clinical, and other testing and a compilation of data relating to the product’s pharmacology, chemistry, manufacture, and controls. The cost of preparing and submitting an NDA or BLA is substantial. The submission of most NDAs and BLAs is additionally subject to a substantial application user fee and the manufacturer and/or sponsor under an approved new drug application are also subject to an annual program fee. These fees are typically increased annually.

The FDA undertakes to perform an initial filing review within 60 days from its receipt of an NDA or BLA to determine whether the application will be accepted for filing based on the agency’s threshold determination that it is sufficiently complete to permit substantive review. Once the submission is accepted for filing, the FDA begins an in-depth review. The FDA has agreed to certain performance goals in the review of NDAs and BLAs. Most such applications for standard review drug or biologic products are reviewed within ten to twelve months; most applications for priority review drugs or biologics are reviewed in six to eight months. The FDA can extend these reviews by three months. Priority review can be applied to drugs that the FDA determines offer major advances in treatment or provide a treatment where no adequate therapy exists. For biologics, priority review is further limited to products intended to treat a serious or life-threatening

15

Table of Contents

disease relative to the currently approved products. The review process for both standard and priority review may be extended by the FDA for three additional months to consider certain late-submitted information, or information intended to clarify information already provided in the submission.

The FDA may also refer applications for novel drug or biologic products, or drug or biologic products that present difficult questions of safety or efficacy, to an advisory committee – typically a panel that includes clinicians and other experts – for review, evaluation, and a recommendation as to whether the application should be approved. The FDA is not bound by the recommendation of an advisory committee, but it generally follows such recommendations. Before approving an NDA or BLA, the FDA will typically inspect one or more clinical sites to assure compliance with GCP. Additionally, the FDA will inspect the facility or the facilities at which the drug is manufactured. FDA will not approve the product unless compliance with current good manufacturing practice, or cGMP, is satisfactory and the NDA or BLA contains data that provide substantial evidence that the drug or biologic is safe and effective in the indication studied.

After the FDA evaluates the NDA or BLA and the manufacturing facilities, it issues either an approval letter or a complete response letter. A complete response letter generally outlines the deficiencies in the submission and may require substantial additional testing, or information, in order for the FDA to reconsider the application. If, or when, those deficiencies have been addressed to the FDA’s satisfaction in a resubmission of the NDA or BLA, the FDA will issue an approval letter. The FDA has committed to reviewing such resubmissions in two or nine months depending on the type of information included.

An approval letter authorizes commercial marketing of the drug or biologic with specific prescribing information for specific indications. As a condition of NDA or BLA approval, the FDA may require a risk evaluation and mitigation strategy, or REMS, to help ensure that the benefits of the drug or biologic outweigh the potential risks. REMS can include medication guides, communication plans for healthcare professionals, and elements to assure safe use, or ETASU. ETASU can include, but are not limited to, special training or certification for prescribing or dispensing, dispensing only under certain circumstances, special monitoring, and the use of patient registries. The requirement for a REMS can materially affect the potential market and profitability of the product. Moreover, product approval may require substantial post-approval testing and surveillance to monitor the product’s safety or efficacy. Once granted, product approvals may be withdrawn if compliance with regulatory standards is not maintained, or problems are identified following initial marketing.

Changes to some of the conditions established in an approved application, including changes in indications, labeling, or manufacturing processes or facilities, require submission and FDA approval of a new NDA or BLA or NDA or BLA supplement before the change can be implemented. In order for Scorpius to manufacture ANTHIM® we will be required to obtain FDA approval for the change in manufacturing facility. An NDA or BLA supplement for a new indication typically requires clinical data similar to that in the original application, and the FDA uses the same procedures and actions in reviewing NDA or BLA supplements as it does in reviewing NDAs or BLAs.

Post-Approval Requirements

Any products for which we receive FDA approvals are subject to continuing regulation by the FDA, including, among other things, record-keeping requirements, reporting of adverse experiences with the product, providing the FDA with updated safety and efficacy information, product sampling and distribution requirements, and complying with FDA promotion and advertising requirements, which include, among others, standards for direct-to-consumer advertising, restrictions on promoting products for uses or in patient populations that are not described in the product’s approved uses, known as ’off-label’ use, limitations on industry-sponsored scientific and educational activities, and requirements for promotional activities involving the internet. Although physicians may prescribe legally available products for off-label uses if the physician deems that use to be appropriate in their professional medical judgment, manufacturers may not market or promote such off-label uses.

In addition, quality control and manufacturing procedures must continue to conform to applicable manufacturing requirements after approval to ensure the long-term stability of the product. cGMP regulations require among other things, quality control and quality assurance as well as the corresponding maintenance of records and documentation and the obligation to investigate and correct any deviations from cGMP. Manufacturers and other entities involved in the

16

Table of Contents

manufacture and distribution of approved products are required to register their establishments with the FDA and certain state agencies and are subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, manufacturers must continue to expend time, money, and effort on production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including, among other things, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending on the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and claims, are also subject to further FDA review and approval.

The FDA also may require post-marketing testing, known as Phase 4 testing, and surveillance to monitor the effects of an approved product. Discovery of previously unknown problems with a product or the failure to comply with applicable FDA requirements can have negative consequences, including adverse publicity, judicial or administrative enforcement, warning letters from the FDA, mandated corrective advertising or communications with doctors, and civil or criminal penalties, among others. Newly discovered or developed safety or effectiveness data may require changes to a product’s approved labeling, including the addition of new warnings and contraindications, and also may require the implementation of other risk management measures. Also, new government requirements, including those resulting from new legislation, may be established, or the FDA’s policies may change, which could delay or prevent regulatory approval of our product candidates under development.

Additional Controls for Biologics

To help reduce the increased risk of the introduction of adventitious agents, the PHSA emphasizes the importance of manufacturing controls for products whose attributes cannot be precisely defined. The PHSA also provides authority to the FDA to immediately suspend licenses in situations where there exists a danger to public health, to prepare or procure products in the event of shortages and critical public health needs, and to authorize the creation and enforcement of regulations to prevent the introduction or spread of communicable diseases in the U.S. and between states.

After a BLA is approved, the product may also be subject to official lot release as a condition of approval. As part of the manufacturing process, the manufacturer is required to perform certain tests on each lot of the product before it is released for distribution. If the product is subject to official release by the FDA, the manufacturer submits samples of each lot of product to the FDA together with a release protocol showing a summary of the history of manufacture of the lot and the results of all of the manufacturer’s tests performed on the lot. The FDA may also perform certain confirmatory tests on lots of some products, such as viral vaccines, before releasing the lots for distribution by the manufacturer. In addition, the FDA conducts laboratory research related to the regulatory standards on the safety, purity, potency, and effectiveness of biological products. As with drugs, after approval of biologics, manufacturers must address any safety issues that arise, are subject to recalls or a halt in manufacturing, and are subject to periodic inspection after approval.

Cell and Tissue-Based Biologics

Establishments that manufacture cell and tissue-based products must comply with the FDA’s current good tissue practices, or cGTP, which are FDA regulations that govern the methods used in, and the facilities and controls used for, the manufacture of such products. The primary intent of the cGTP requirements is to ensure that T-cell and tissue-based products are manufactured in a manner designed to prevent the introduction, transmission and spread of communicable disease. FDA regulations also include requirements for a unified registration and listing system, donor screening and testing, adverse reaction reporting, and labeling.

Cell and tissue-based products may also be subject to the same approval standards, including demonstration of safety and efficacy, as other biologic and drug products if they meet certain criteria such as if the cells or tissues are more than minimally manipulated or if they are intended for a non-homologous use. Marketing of these products in the U.S. will require FDA approval under the BLA pathway as discussed above.

CDMO Regulatory Approval

We are required to comply with the regulatory requirements of various local, state, national and international regulatory bodies having jurisdiction in the countries or localities where we manufacture products or where our customers’ products are distributed. In particular, we are subject to laws and regulations concerning research and development, testing, manufacturing processes, equipment and facilities, including compliance with CGMPs, labeling and distribution, import and export, and product registration and listing. As a result, our facilities are subject to regulation by the FDA, as well as regulatory bodies of other jurisdictions where our customers have marketing approval for their products including, but not limited to, the EMA, ANVISA, Health Canada, and the Australian Department of Health. Scorpius is subject to periodic unannounced inspections by the FDA and certain state agencies for compliance with cGMP and other laws. Accordingly, Scorpius must continue to expend time, money, and effort in the area of production and quality control to maintain cGMP compliance. Discovery of problems with a product after approval may result in restrictions on a product, manufacturer, or holder of an approved BLA, including, among other things, recall or withdrawal of the product from the market. In addition, changes to the manufacturing process are strictly regulated, and depending on the significance of the change, may require prior FDA approval before being implemented. Other types of changes to the approved product, such as adding new indications and claims, are also subject to further FDA review and approval.

​

We are also required to comply with environmental, health and safety laws and regulations, as discussed in “Environmental and Safety Matters” below. These regulatory requirements impact many aspects of our operations, including manufacturing, developing, labeling, packaging, storage, distribution, import and export and record keeping related to customers’ products. Noncompliance with any applicable regulatory requirements can result in government refusal to approve facilities for manufacturing products or products for commercialization.

​

Our customers’ products must undergo pre-clinical and clinical evaluations relating to product safety and efficacy before they are approved as commercial therapeutic products. The regulatory authorities having jurisdiction in the countries in which our customers intend to market their products may delay or put on hold clinical trials, delay approval of a product or determine that the product is not approvable. The FDA or other regulatory agencies can delay approval of a drug if our manufacturing facilities are not able to demonstrate compliance with CGMPs, pass other aspects of pre-approval inspections (i.e., compliance with filed submissions) or properly scale up to produce commercial supplies. The FDA and comparable government authorities having jurisdiction in the countries in which our customers intend to market their products have the authority to withdraw product approval or suspend manufacture if there are significant problems with raw materials or supplies, quality control and assurance or the product is deemed adulterated or misbranded. If new legislation or regulations are enacted or existing legislation or regulations are amended or are interpreted or enforced differently, we may be required to obtain additional approvals or operate according to different manufacturing or operating standards or pay additional fees. This may require a change in our manufacturing techniques or additional capital investments in our facilities.

​

The costs associated with complying with the various applicable local, state, national and international regulations could be significant and the failure to comply with such legal requirements could have an adverse effect on our financial condition and results of operations. See “Risk Factors—Risks Related to Our Business” for additional discussion of the costs associated with complying with the various regulations. Failure to comply with existing and future regulatory requirements could adversely affect our business, financial condition and results of operations.

Environmental and Safety Matters

​

Certain products manufactured by us involve the use, storage and transportation of toxic and hazardous materials. Our operations are subject to extensive laws and regulations relating to the storage, handling, emission, transportation and discharge of materials into the environment and the maintenance of safe working conditions. We maintain environmental and industrial safety and health compliance programs and training at our facilities.

​

Prevailing legislation tends to hold companies primarily responsible for the proper disposal of their waste even after transfer to third party waste disposal facilities. Other future developments, such as increasingly strict environmental, health and safety laws and regulations, and enforcement policies, could result in substantial costs and liabilities to us and could

18

Table of Contents

subject the handling, manufacture, use, reuse or disposal of substances or pollutants at our facilities to more rigorous scrutiny than at present.

​

Other U.S. Healthcare Laws and Compliance Requirements

In the United States, our activities are potentially subject to regulation by various federal, state and local authorities in addition to the FDA, including but not limited to, the Centers for Medicare and Medicaid Services, or CMS, other divisions of the U.S. Department of Health and Human Services, for instance the Office of Inspector General, the U.S. Department of Justice (“DOJ”), and individual U.S. Attorney offices within the DOJ, and state and local governments. For example, sales, marketing and scientific/educational grant programs must comply with the anti-fraud and abuse provisions of the Social Security Act, the false claims laws, the physician payment transparency laws, the privacy and security provisions of HIPAA, as amended by HITECH, and similar state laws, each as amended.

The federal anti-kickback statute prohibits, among other things, any person or entity, from knowingly and willfully offering, paying, soliciting or receiving any remuneration, directly or indirectly, overtly or covertly, in cash or in kind, to induce or in return for purchasing, leasing, ordering or arranging for the purchase, lease or order of any item or service reimbursable under Medicare, Medicaid or other federal healthcare programs. The term remuneration has been interpreted broadly to include anything of value. The anti-kickback statute has been interpreted to apply to arrangements between pharmaceutical manufacturers on one hand and prescribers, purchasers, and formulary managers on the other. There are a number of statutory exceptions and regulatory safe harbors protecting some common activities from prosecution. The exceptions and safe harbors are drawn narrowly and practices that involve remuneration that may be alleged to be intended to induce prescribing, purchasing or recommending may be subject to scrutiny if they do not qualify for an exception or safe harbor. Our practices may not in all cases meet all of the criteria for protection under a statutory exception or regulatory safe harbor. Failure to meet all of the requirements of a particular applicable statutory exception or regulatory safe harbor, however, does not make the conduct per se illegal under the anti-kickback statute. Instead, the legality of the arrangement will be evaluated on a case-by-case basis based on a cumulative review of all of its facts and circumstances. Violations of this law are punishable by imprisonment, criminal fines, administrative civil money penalties and exclusion from participation in federal healthcare programs.

Additionally, the intent standard under the anti-kickback statute was amended by the Affordable Care Act to a stricter standard such that a person or entity no longer needs to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation. In addition, the Patient Protection and Affordable Care Act, as amended by the Health Care and Education Reconciliation Act of 2010, or collectively the ACA, provides that the government may assert that a claim including items or services resulting from a violation of the federal Anti Kickback Statute constitutes a false or fraudulent claim for purposes of the federal civil False Claims Act., as discussed below.

The civil monetary penalties statute imposes penalties against any person or entity that, among other things, is determined to have presented or caused to be presented a claim to a federal health program that the person knows or should know is for an item or service that was not provided as claimed or is false or fraudulent.

Although we would not submit claims directly to payors, drug manufacturers can be held liable under the federal civil False Claims Act, which imposes civil penalties, including through civil whistleblower or qui tam actions, against individuals or entities (including manufacturers) for, among other things, knowingly presenting, or causing to be presented to federal programs (including Medicare and Medicaid) claims for items or services, including drugs, that are false or fraudulent, claims for items or services not provided as claimed, or claims for medically unnecessary items or services; making a false statement or record material to payment of a false claim; or avoiding, decreasing or concealing an obligation to pay money to the federal government. Penalties for a False Claims Act violation include three times the actual damages sustained by the government, plus mandatory civil penalties for each separate false claim, the potential for exclusion from participation in federal healthcare programs and, although the federal False Claims Act is a civil statute, conduct that results in a False Claims Act violation may also implicate various federal criminal statutes. The government may deem manufacturers to have “caused” the submission of false or fraudulent claims by, for example, providing inaccurate billing or coding information to customers or promoting a product off-label. Claims which include items or services resulting from a violation of the federal Anti-Kickback Statute are false or fraudulent claims for purposes of the False Claims Act. Our future marketing and activities relating to the reporting of wholesaler or estimated retail prices for our products, if

19

Table of Contents

approved, the reporting of prices used to calculate Medicaid rebate information and other information affecting federal, state and third-party reimbursement for our products, and the sale and marketing of our product and any future product candidates, are subject to scrutiny under this law. Pharmaceutical and other healthcare companies have been prosecuted under these laws for allegedly providing free product to customers with the expectation that the customers would bill federal programs for the product. Other companies have been prosecuted for causing false claims to be submitted because of the companies’ marketing of the product for unapproved, and thus non-reimbursable, uses.

HIPAA created new federal criminal statutes that prohibit knowingly and willfully executing, or attempting to execute, a scheme to defraud or to obtain, by means of false or fraudulent pretenses, representations or promises, any money or property owned by, or under the control or custody of, any healthcare benefit program, including private third-party payors and knowingly and willfully falsifying, concealing or covering up by trick, scheme or device, a material fact or making any materially false, fictitious or fraudulent statement in connection with the delivery of or payment for healthcare benefits, items or services. Similar to the federal anti-kickback statute, a person or entity does not need to have actual knowledge of the statute or specific intent to violate it in order to have committed a violation.

We may be subject to data privacy and security regulations by both the federal government and the states in which we conduct business. HIPAA, as amended by the HITECH Act, and their respective implementing regulations. Among other things, HITECH makes HIPAA’s privacy and security standards directly applicable to business associates, defined as independent contractors or agents of covered entities, which include health care providers, health plans, and healthcare clearinghouse, that create, receive, or obtain protected health information in connection with providing a service on behalf of a covered entity. HITECH also increased the civil and criminal penalties that may be imposed against covered entities and business associates, and gave state attorneys general new authority to file civil actions for damages or injunctions in federal courts to enforce the federal HIPAA laws and seek attorney’s fees and costs associated with pursuing federal civil actions. In addition, certain state laws govern the privacy and security of health information in specified circumstances, some of which are more stringent and many of which differ from each other in significant ways, thus complicating compliance efforts. Failure to comply with these laws, where applicable, can result in the imposition of significant civil and criminal penalties.

Additionally, the Federal Physician Payments Sunshine Act under the ACA, and its implementing regulations, require that certain manufacturers of drugs, devices, biological and medical supplies for which payment is available under Medicare, Medicaid or the Children’s Health Insurance Program (with certain exceptions) to annually report to the Centers for Medicare and Medicaid, or CMS, information related to certain payments or other transfers of value made or distributed to physicians and teaching hospitals, or to entities or individuals at the request of, or designated on behalf of, the physicians and teaching hospitals and to report annually certain ownership and investment interests held by physicians and their immediate family members. Failure to submit timely, accurately, and completely the required information may result in civil monetary penalties. Certain states also mandate implementation of compliance programs, impose restrictions on pharmaceutical manufacturer marketing practices and/or require the tracking and reporting of gifts, compensation and other remuneration to healthcare providers and entities.

In order to distribute products commercially, we must also comply with state laws that require the registration of manufacturers and wholesale distributors of drug and biological products in a state, including, in certain states, manufacturers and distributors who ship products into the state even if such manufacturers or distributors have no place of business within the state. Some states also impose requirements on manufacturers and distributors to establish the pedigree of product in the chain of distribution, including some states that require manufacturers and others to adopt new technology capable of tracking and tracing product as it moves through the distribution chain. Several states have enacted legislation requiring pharmaceutical and biotechnology companies to establish marketing compliance programs, file periodic reports with the state, make periodic public disclosures on sales, marketing, pricing, clinical trials and other activities, and/or register their sales representatives, as well as to prohibit pharmacies and other healthcare entities from providing certain physician prescribing data to pharmaceutical and biotechnology companies for use in sales and marketing, and to prohibit certain other sales and marketing practices. All of our activities are potentially subject to federal and state consumer protection and unfair competition laws.

If our operations are found to be in violation of any of the federal and state healthcare laws described above or any other governmental regulations that apply to it, we may be subject to penalties, including without limitation, significant civil,

20

Table of Contents

criminal and/or administrative penalties, damages, fines, disgorgement, imprisonment, exclusion from participation in government programs, such as Medicare and Medicaid, injunctions, private “qui tam” actions brought by individual whistleblowers in the name of the government, or refusal to enter into government contracts, contractual damages, reputational harm, administrative burdens, diminished profits and future earnings, and the curtailment or restructuring of operations, any of which could adversely affect our ability to operate our business and our results of operations. If any of the physicians or other healthcare providers or entities with whom we expect to do business is found to be not in compliance with applicable laws, they may be subject to criminal, civil or administrative sanctions, including exclusions from government funded healthcare programs. Ensuring business arrangements comply with applicable healthcare laws, as well as responding to possible investigations by government authorities, can be time- and resource-consuming and can divert a company’s attention from the business.

Strict data privacy laws regulating the collection, transmission, storage and use of employee data and consumers’ personally-identifying information are evolving in the EU, U.S. and other jurisdictions in which we operate. Outside of the U.S., the laws, regulations and standards in many jurisdictions apply broadly to the collection, use, and other processing of personal information. For example, in the EU, the collection and use of personal data is governed by the provisions of the General Data Protection Regulation (the “GDPR”). The GDPR, together with national legislation, regulations and guidelines of the EU member states governing the processing of personal data, impose strict obligations on entities subject to the GDPR, including but not limited to: (i) accountability and transparency requirements, and enhanced requirements for obtaining valid consent from data subjects; (ii) obligations to consider data protection as any new products or services are developed and to limit the amount of personal data processed; (iii) obligations to comply with the data protection rights of data subjects; and (iv) obligations to report certain personal data breaches to governmental authorities and individuals. Data protection authorities from the different E.U. member states and other European countries may enforce the GDPR and national data protection laws differently, and introduce additional national regulations and guidelines, which adds to the complexity of processing European personal data. Failure to comply with the requirements of the GDPR and the related national data protection laws may result in significant monetary fines and other administrative penalties (the GDPR authorizes fines for certain violations of up to 4% of global annual revenue or €20 million, whichever is greater) as well as civil liability claims from individuals whose personal data was processed. Additionally, expenses associated with compliance could reduce our operating margins.

The GDPR also prohibits the transfer of personal data from the E.U. to countries outside of the E.U. unless made to a country deemed by the European Commission to provide adequate protection for personal data or accomplished by means of an approved data transfer mechanism (e.g., standard contractual clauses). Data protection authority guidance and enforcement actions that restrict companies’ ability to transfer data may increase risk relating to data transfers or make it more difficult or impossible to transfer E.U. personal data to the U.S.

Coverage, Pricing and Reimbursement

Significant uncertainty exists as to the coverage and reimbursement status of any product candidates for which we obtain regulatory approval. In the U.S. and markets in other countries, sales of any products for which we receive regulatory approval for commercial sale will depend, in part, on the extent to that third-party payors provide coverage, and establish adequate reimbursement levels for such products. In the U.S., third-party payors include federal and state healthcare programs, private managed care providers, health insurers and other organizations. The process for determining whether a third-party payor will provide coverage for a product may be separate from the process for setting the price of a product or for establishing the reimbursement rate that such a payor will pay for the product. Third-party payors may limit coverage to specific products on an approved list, also known as a formulary, which might not include all of the FDA-approved products for a particular indication. Third-party payors are increasingly challenging the price, examining the medical necessity and reviewing the cost- effectiveness of medical products, therapies and services, in addition to questioning their safety and efficacy. We may need to conduct expensive pharmaco-economic studies in order to demonstrate the medical necessity and cost-effectiveness of our product candidates, in addition to the costs required to obtain the FDA approvals. Our product candidates may not be considered medically necessary or cost-effective. A payor’s decision to provide coverage for a product does not imply that an adequate reimbursement rate will be approved. Further, one payor’s determination to provide coverage for a product does not assure that other payors will also provide coverage for the product. Adequate third-party reimbursement may not be available to enable us to maintain price levels sufficient to realize an appropriate return on investment in product development.

Different pricing and reimbursement schemes exist in other countries. Some jurisdictions operate positive and negative list systems under which products may only be marketed once a reimbursement price has been agreed. To obtain reimbursement or pricing approval, some of these countries may require the completion of clinical trials that compare the cost-effectiveness of a particular product candidate to currently available therapies. Other countries allow companies to fix their own prices for medicines but monitor and control company profits. The downward pressure on health care costs has become very intense. As a result, increasingly high barriers are being erected to the entry of new products. In addition, in some countries, cross-border imports from low-priced markets exert a commercial pressure on pricing within a country.

The marketability of any product candidate for which we receive regulatory approval for commercial sale may suffer if the government and third-party payors fail to provide adequate coverage and reimbursement. In addition, emphasis on managed care in the U.S. has increased and we expect the pressure on healthcare pricing will continue to increase. Coverage policies and third-party reimbursement rates may change at any time. Even if favorable coverage and reimbursement status is attained for one or more products for which we receive regulatory approval, less favorable coverage policies and reimbursement rates may be implemented in the future.

U.S. Healthcare Reform

In the U.S. and some foreign jurisdictions, there have been, and likely will continue to be, a number of legislative and regulatory changes and proposed changes regarding the healthcare system directed at broadening the availability of healthcare, improving the quality of healthcare, and containing or lowering the cost of healthcare.

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. It is unclear how these challenges and other efforts to repeal and replace the ACA will impact our business in the future.

Other legislative changes have been proposed and adopted in the U.S. since the ACA was enacted. Additionally, there have been several recent U.S. Congressional inquiries and proposed bills designed to, among other things, bring more transparency to drug pricing, review the relationship between pricing and manufacturer patient programs and reform government program reimbursement methodologies for drugs.

We cannot predict what healthcare reform initiatives may be adopted in the future. Further federal, state and foreign legislative and regulatory developments are likely, and we expect ongoing initiatives to increase pressure on drug pricing. Such reforms could have an adverse effect on anticipated revenues from product candidates and may affect our overall financial condition and ability to develop product candidates.

We anticipate that current and future U.S. legislative healthcare reforms may result in additional downward pressure on the price that we receive for any approved product, if covered, and could seriously harm our business. Any reduction in reimbursement from Medicare and other government programs may result in a similar reduction in payments from private payors.

Non-U.S. Regulation

Before our products can be marketed outside of the U.S., they are subject to regulatory approval of the respective authorities in the country in which the product should be marketed. The requirements governing the conduct of clinical trials, product licensing, pricing and reimbursement vary widely from country to country. No action can be taken to market any product in a country until an appropriate application has been approved by the regulatory authorities in that country. The current approval process varies from country to country, and the time spent in gaining approval varies from that required for FDA approval. In certain countries, the sales price of a product must also be approved. The pricing review period often begins after market approval is granted. Even if a product is approved by a regulatory authority, satisfactory prices might not be approved for such product.

In Europe, marketing authorizations may be submitted at a centralized, a decentralized or national level; however, the centralized procedure is mandatory for the approval of biotechnology products and provides for the grant of a single

22

Table of Contents

marketing authorization that is valid in all EU member states. There can be no assurance that the chosen regulatory strategy will secure regulatory approval on a timely basis or at all.

While we intend to market our products outside the U.S. in compliance with our respective license agreements, we have not made any applications with non-U.S. authorities and have no timeline for such applications or marketing.

Research and Development

We have built an internal and external research and development organization that includes expertise in discovery research, preclinical development, product formulation, analytical chemistry, manufacturing, clinical development, and regulatory and quality assurance. Sponsors of clinical trials of FDA-regulated products, including drugs, are required to register and disclose certain clinical trial information. Our cancer trials have been registered on clinicaltrials.gov. Information related to the product, patient population, phase of investigation, study sites and investigators, and other aspects of the clinical trial is then made public as part of the registration. Sponsors are also obligated to discuss the results of their clinical trials after completion. Disclosure of the results of these trials can be delayed until the new product or new indication being studied has been approved. Competitors may use this publicly available information to gain knowledge regarding the progress of development. Research and development expenses were $23.5 million and $16.5 million during the years ended December 31, 2022 and 2021, respectively.

We formed Heat Biologics GmbH (Heat GmbH), a wholly-owned limited liability company, organized in Germany on September 11, 2012 and Heat Biologics Australia Pty LTD, a wholly-owned company, registered in Australia on March 14, 2014. On October 25, 2016, we formed a wholly-owned subsidiary, Zolovax, Inc., to focus on the development of gp96 based vaccines targeting Zika, HIV, West Nile, dengue, yellow fever, and SARS-CoV-2. In June 2012, we divested our 92.5% interest in Pelican (formerly known as Heat Biologics II, Inc.). On April 28, 2017, we completed the acquisition of an 80% controlling interest in Pelican, a related party prior to acquisition. In October 2018, we entered into an agreement with UM whereby UM exchanged its shares of stock in Heat’s subsidiaries, Heat I and Pelican, resulting in us owning 100% of Heat I and increasing our controlling ownership in Pelican from 80% to 85%. We assigned our proprietary rights related to the development and application of our ImPACT® therapy platform to Heat Biologics I, Inc. In November 2018, we formed Skunkworx (formerly known as Delphi Therapeutics, Inc.) which uses a unique and proprietary platform to generate new biological entities that we may rapidly advance into clinical development. Also, in November 2018, we formed Scorpius BioManufacturing, Inc. (“Scorpius”) (formerly known as Scorpion Biological Services, Inc.), to focus on developing bioanalytic, process development and manufacturing capability to service our in-house requirements as well as potentially those of others.

opportunities related to our business. In April 2022, we formed Elusys to focus on commercializing ANTHIM® and developing additional biodefense product candidates.

We are a “smaller reporting company”, as defined in Regulation S-K. Smaller reporting companies may take advantage of certain reduced disclosure obligations, including, among other things, providing only two years of audited financial statements. We will cease to be a smaller reporting company if we have (i) more than $250 million in market value of our shares held by non-affiliates as of the last business day of our most recently completed second fiscal quarter or (ii) more than $100 million of annual revenues in our most recent fiscal year completed before the last business day of our second fiscal quarter and a market value of our shares held by non-affiliates more than $700 million as of the last business day of our second fiscal quarter.

Human Capital

We believe that our success depends upon our ability to attract, develop, retain and motivate key personnel. Our management and scientific teams possess considerable experience in drug discovery, research and development, manufacturing, clinical and regulatory affairs and believe we directly benefit from this experience and industry knowledge. Our research team comprises B.S., M.S. and Ph.D.-level scientists with expertise in oncology, immunology, and molecular biology.

As of December 31, 2022, we had a total of 77 full-time employees, of which 29 are part of our research team located in San Antonio, Texas, 16 are part of our research team located in Morrisville, North Carolina, 5 are part of our research team located in New Brunswick, New Jersey, 3 are part of our research team located in Parsippany, New Jersey and 24 are part of our corporate team. We consider our relationships with our employees to be good. None of our employees is represented by a labor union. We anticipate that we will need to identify, attract, train and retain other highly skilled personnel to pursue our development program. Hiring for such personnel is competitive, and there can be no assurance that we will be able to retain our key employees or attract, assimilate or retain the qualified personnel necessary for the development of our business.

Although, management continually seeks to add additional talent to its work force, management believes that it has sufficient human capital to operate its business successfully.

Our compensation programs are designed to align the compensation of our employees with our performance and to provide the proper incentives to attract, retain and motivate employees to achieve superior results. The structure of our compensation programs balances incentive earnings for both short-term and long-term performance. Specifically:

| ● | we provide employee wages that are competitive and consistent with employee positions, skill levels, experience, knowledge and geographic location;

| ● | we engage nationally recognized outside compensation and benefits consulting firms to independently evaluate the effectiveness of our executive compensation and benefit programs and to provide benchmarking against our peers within the industry;

| ● | we align our executives’ long-term equity compensation with our shareholders’ interests by linking realizable pay with stock performance;

| ● | annual increases and incentive compensation are based on merit, which is communicated to employees at the time of hiring and documented through our talent management process as part of our annual review procedures and upon internal transfer and/or promotion; and

| ● | all employees are eligible for health insurance, paid and unpaid leaves, a 401K retirement plan with employer matching contributions (maximum of 4% match) and life and disability/accident coverage. We also offer a variety of voluntary benefits that allow employees to select the options that meet their needs.

Item 1A. Risk Factors

Investors should carefully consider the risks described below before deciding whether to invest in our securities. If any of the following risks actually occur, our business, financial condition or results of operations could be adversely affected. In such case, the trading price of our common stock could decline and you could lose all or part of your investment. Our actual results could differ materially from those anticipated in the forward-looking statements made throughout this Annual Report a result of different factors, including the risks we face described below.

Risks Relating to our Financial Position and Capital Requirements

To date, we have not generated significant revenue and we do not anticipate generating significant revenue in the near future.

To date, we have not generated any revenue from product sales and substantially all of our revenue to date has been revenue from one order of ANTHIM®, grant revenue that Pelican has received from CPRIT and a small amount of revenue from a research funding agreement. We do not anticipate generating any significant revenue from product sales for several years as to date we have only one product, ANTHIM®, approved for commercial sale and it will take several years for us to manufacture additional quantity of ANTHIM® for sale and receive any necessary regulatory approvals. Although we acquired inventory of ANTHIM®, we did not acquire a significant amount of inventory for sale. Therefore, we do not anticipate generating significant revenue from ANTHIM® sales for several years and in fact anticipate to incur additional expenses associated with such product before generating significant revenue from sales of ANTHIM®. Even if we generate revenue from product sales, which is not anticipated for several years, if at all, there can be no assurance that we will be profitable. In addition, we have entered into a new line of business, the provision of contract development and manufacturing services and no assurance can be given that we will be able to generate significant revenue as a contract development and manufacturing organization (“CDMO”) or that we will be able to consummate our business strategy and plans. Financial, technological, market, or other limitations may force us to modify, alter, significantly delay, or significantly impede the implementation of such plans. The operation of the manufacturing facility required us to incur significant expenses before we realize any revenue from such facility. We have insufficient results for investors to use to identify historical trends. Investors should consider our prospects in light of the risk, expenses and difficulties we will encounter as an early-stage company. Our revenue and income potential is unproven and our business model is continually evolving. We are subject to the risks inherent to the operation of a new business enterprise and cannot assure you that we will be able to successfully address these risks.

Our consolidated financial statements have been prepared assuming that we will continue as a going concern.

​

We have an accumulated deficit of $209.2 million as of December 31, 2022 and a net loss of approximately $43.9 million for the year ended December 31, 2022 and have not generated significant revenue or positive cash flows from operations. The Company expects to incur significant expenses and continued losses from operations for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, particularly as we ramp up operations in our in-house bioanalytic, process development and manufacturing facility in San Antonio, TX, expand our infectious disease/biological threat program, and continue to support the development of, and commencement of operations at, a new biodefense-focused large molecule and biologics biomanufacturing facility in Manhattan, Kansas. Our audited financial statements for the fiscal year ended December 31, 2022 were prepared under the assumption that we will continue as a going concern; however, we have incurred significant losses from operations to date and we expect our expenses to increase in connection with our ongoing activities. These factors raise substantial doubt about our ability to continue as a going concern for one year after the financial statements are issued. Our auditors also included an explanatory paragraph in its report on our financial statements as of and for the year ended December 31, 2022 with respect to this uncertainty. There can be no assurance that funding will be available on acceptable terms on a timely basis, or at all. The various ways that we could raise capital carry potential risks. Any additional sources of financing will likely involve the issuance of our equity securities, which will have a dilutive effect on our stockholders. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business. If we raise funds through collaborations and licensing arrangements, we might be required to relinquish significant rights to our technologies or tests or grant licenses on terms that are not favorable to us. If we do not succeed in raising additional funds on acceptable terms or at all, we may be unable to complete planned build out of our Kansas facility or develop any new product candidates that we acquire. As

25

Table of Contents

such, we cannot conclude that such plans will be effectively implemented within one year after the date that the financial statements included in this Annual Report are filed with the SEC and there is uncertainty regarding our ability to maintain liquidity sufficient to operate our business effectively, which raises substantial doubt about our ability to continue as a going concern.

​

We have a limited operating history in our current lines of business.

Our success is dependent upon our ability to obtain regulatory approval for commercial sale of our products and to sell such products. We have not yet demonstrated an ability to perform the functions necessary for the approval or successful commercialization of any product candidates. To date, we have not obtained approval for commercialization of any of the products we have developed and, due to our limited time owning ANTHIM®, we have not proven that we can successfully commercialize any product. In addition, we have recently shifted our focus to the development and commercialization of biodefense products and provision of CDMO services. To date, we have generated $6.0 million from new sales of ANTHIM® subsequent to our acquisition of Elusys. To date, we have provided limited manufacturing services as a contract development and manufacturing organization and we have not proven that we can successfully operate a CDMO facility. The successful commercialization of any product candidates will require us to perform a variety of functions, including:

| ● | undertaking preclinical development and successfully enrolling patients in clinical trials;

| ● | participating in regulatory approval processes;

| ● | formulating and manufacturing products; and

| ● | conducting sales and marketing activities.

Until the last few years, our operations have been limited primarily to organizing and staffing, acquiring, developing and securing our proprietary technology and undertaking preclinical trials and preparing for and conducting our Phase 1 and Phase 2 clinical and preclinical trials of our product candidates for cancer and related indications. These operations provide a limited basis for you to assess our ability to successfully commercialize ANTHIM® and any other biodefense product we develop or acquire or to provide CDMO services.

We have incurred net losses every year since our inception and expect to continue to incur increased expenses and generate operating losses and experience negative cash flows and it is uncertain whether we will achieve profitability.

For the years ended December 31, 2022 and 2021, we incurred a net loss of $43.9 million and $35.4 million, respectively. We have an accumulated deficit of $209.2 million through December 31, 2022. We expect to continue to incur operating losses until such time, if ever, as we are able to achieve sufficient levels of revenue from operations. As stated above, we do not anticipate generating significant revenue from sales of our products for several years or from our manufacturing facility until such time as it is fully operational and operating at full capacity. Our ability to achieve profitability will depend on us successfully manufacturing and receiving regulatory approval for ANTHIM® and our other product candidates and market acceptance of our product offerings and services and our capacity to develop, introduce and sell our products and services to our targeted markets. There can be no assurance that future manufacturing of ANTHIM® will be approved or any of our product candidates that are under development will be approved for commercial sale, or even product candidates and products that are approved for commercial sale we will ever generate significant sales or achieve profitability. Furthermore, there can be no assurance that we generate sufficient revenue from manufacturing services to support the expenses anticipated to be incurred by the manufacturing facility. Accordingly, the extent of future losses and the time required to achieve profitability, if ever, cannot be predicted at this point.

Even if we succeed in developing and commercializing one or more product candidates, and are successful in selling ANTHIM® or are successful in generating revenue as a CDMO, we expect to incur substantial losses for the foreseeable future and may never become profitable. We also expect to continue to incur significant operating expenses and anticipate that our expenses will increase substantially in the foreseeable future as we:

​

| ● | continue to undertake preclinical development and conduct clinical trials for product candidates;

| ● | seek regulatory approvals for product candidates;

| ● | implement additional internal systems and infrastructure;

26

Table of Contents

| ● | devote resources to constructing a facility for the development of bioanalytics, process development and manufacturing activities;

| ● | sell ANTHIM® and engage in commercial scale manufacturing of ANTHIM®; and

| ● | hire additional personnel.

​

We also expect to experience negative cash flows for the foreseeable future as we fund our operating losses. As a result, we will need to generate significant revenues or raise additional financing in order to achieve and maintain profitability. We may not be able to generate these revenues or achieve profitability in the future. Our failure to achieve or maintain profitability would likely negatively impact the value of our securities and financing activities.

We will need to raise additional capital to support our long-term business plans and our failure to obtain funding when needed may force us to delay, reduce or eliminate our development programs or commercialization efforts.

During the year ended December 31, 2022, our operating activities used net cash of approximately $5.7 million and as of December 31, 2022, our cash and cash equivalents and short-term investments were approximately $44.3 million. During the year ended December 31, 2021, our operating activities used net cash of approximately $38.1 million and as of December 31, 2021 our cash and cash equivalents and short-term investments were approximately $96.4 million. We have experienced significant losses since inception and have a significant accumulated deficit. As of December 31, 2022, our accumulated deficit totaled $209.2 million and as of December 31, 2021, our accumulated deficit totaled $165.7 million on a consolidated basis. We expect to incur additional operating losses in the future and therefore expect our cumulative losses to increase. We do not expect to derive significant revenue from our CDMO services, any of our product candidates currently in development in the near future until we or our potential partners successfully commercialize our products and in order to generate significant revenue from ANTHIM® sales we will need to engage in full scale manufacturing of ANTHIM® which will take several years. We expect our expenses to increase if and when commence full scale manufacturing of ANTHIM®. Our agreement with Lonza obligates us to pay for certain services upon placement of an order and only allows us to cancel manufacturing of batches for which we have placed orders under certain circumstances and based upon the order that we placed on March 31, 2023, we anticipate being obligated to pay over a two year period to Lonza approximately $34 million and and an additional $19 million for resins and other raw materials required for production. In addition, we expect our expenses to increase due to the operation of the manufacturing facility in San Antonio and the build out and purchase of equipment for the facility in Kansas.

We will need to raise additional capital to fund our long-term operations and we cannot be certain that funding will be available to us on acceptable terms on a timely basis, or at all. To meet our financing needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which we expect will include sales of common stock through at the market issuances, debt financings and/or funding from partnerships or collaborations. Our ability to raise capital through the sale of securities may be limited by our number of authorized shares of common stock and various rules of the SEC and the NYSE American that place limits on the number and dollar amount of securities that we may sell. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive effect on our stockholders, assuming we are able to sufficiently increase our authorized number of shares of common stock. To the extent that we raise additional funds by issuing equity securities, our stockholders may experience significant dilution. Any debt financing, if available, may involve restrictive covenants that may impact our ability to conduct our business. If we fail to raise additional funds on acceptable terms, we may be unable to complete planned preclinical and clinical trials or obtain approval of our product candidates from the FDA and other regulatory authorities or continue to maintain our listing on the NYSE American. In addition, we could be forced to delay, discontinue or curtail product development, forego sales and marketing efforts, and forego licensing in attractive business opportunities. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive effect on our stockholders.

​

We face risks related to the restatement of our previously issued financial statements for the quarters ended June 30, 2022 and September 30, 2022.

​

As discussed in the Explanatory Note and in Note 17 to the consolidated financial statements in this Annual Report, we reached a determination to restate our unaudited consolidated financial statements included in the quarterly reporting periods during fiscal year 2022, consisting of June 30, 2022 and September 30, 2022 and that such interim financial

27

Table of Contents

statements should no longer be relied upon. As a result, we have incurred unanticipated costs for accounting and legal fees in connection with or related to the restatement, and have become subject to a number of additional risks and uncertainties, which may affect investor confidence in the accuracy of our financial disclosures and may raise reputational issues for our business. we expect to continue to face many of the risks and challenges related to the restatement, including the following:

| ● | we may fail to remediate material weaknesses in our internal control over financial reporting and other material weaknesses may be identified in the future, which would adversely affect the accuracy and timing of our financial reporting;

| ● | the processes undertaken to effect the restatement may not have been adequate to identify and correct all errors in our historical financial statements and, as a result, we may discover additional errors and our financial statements remain subject to the risk of future restatement;

| ● | the incurrence of restatement-related expenses; and

| ● | diversion of management and other human resources attention from the operation of our business.

We cannot assure that all of the risks and challenges described above will be eliminated and that lost business opportunities can be recaptured or that general reputational harm will not persist. If one or more of the foregoing risks or challenges persist, our business, operations and financial condition are likely to be materially and adversely affected

​

We identified a material weakness in our internal control over financial reporting and determined that our disclosure controls and procedures were ineffective as of June 30, 2022 and September 30, 2022 as well as of December 31, 2022. As a result, we restated our quarterly financial results for the periods ending June 30, 2022 and September 30, 2022. In the future, we may identify additional material weaknesses or otherwise fail to maintain an effective system of internal control over financial reporting or adequate disclosure controls and procedures, which may result in material errors in our financial statements or cause us to fail to meet our period reporting obligations.

Management and our Audit Committee, in consultation with BDO USA LLP (“BDO”), our independent registered public accounting firm, determined that our previously issued interim financial statements filed on the Form 10-Q, as of June 30, 2022, and for the three and six months ended June 30, 2022 and three and nine months ended September 30, 2022 should no longer be relied upon. Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for evaluating and reporting on the effectiveness of our system of internal control. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external reporting purposes in accordance with accounting principles generally accepted in the United States of America. As a public company, we are required to comply with the Sarbanes-Oxley Act and other rules that govern public companies. In particular, we are required to certify our compliance with Section 404 of the Sarbanes-Oxley Act, which requires us to furnish annually a report by management on the effectiveness of our internal control over financial reporting.

​

Management has concluded that in light of the errors described above, a material weakness in the Company’s internal controls over financial reporting existed and management’s assessment of the effectiveness of the Company’s disclosure controls and procedures as of June 30, 2022 and September 30, 2022 set forth in it Quarterly Reports on Form 10-Q for the quarters ended June 30, 2022 and September 30, 2022 need to be modified to include a material weakness in its controls over financial reporting. The material weakness identified relates to the the ineffective design of management review controls over the computation and disclosure of income taxes. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of a company’s annual or interim financial statements will not be prevented or detected on a timely basis. The existence of one or more material weaknesses precludes a conclusion by management that the Company’s disclosure controls and procedures and internal control over financial reporting are effective. As a result of the material weakness, the Company believes that its internal control over financial reporting was not effective and its disclosure controls and procedures were not effective for the Non-Reliance Periods.

​

If we are not able to comply with the requirements of the Sarbanes-Oxley Act or if we are unable to maintain effective internal control over financial reporting, we may not be able to produce timely and accurate financial statements or guarantee that information required to be disclosed by us in the reports that we file with the SEC, is recorded, processed, summarized, and reported within the time periods specified in SEC rules and forms. Any failure of our internal control

28

Table of Contents

over financial reporting or disclosure controls and procedures could cause our investors to lose confidence in our publicly reported information, cause the market price of our stock to decline, expose us to sanctions or investigations by the SEC or other regulatory authorities, or impact our results of operations.

​

In order to develop ANTHIM®, we will have to devote significant resources to ANTHIM®.

​

Pursuant to the terms of the Merger Agreement, we have agreed to use reasonable efforts to commercialize ANTHIM®. Obtaining requisite regulatory approvals for the manufacture and sale of ANTHIM® and manufacturing costs are anticipated to be significant. Our agreement with Lonza obligates us to pay for certain services upon placement of an order and only allows us to cancel manufacturing of batches for which we have placed orders under certain circumstances. Based upon the order that we placed in March 2023, we anticipate being obligated to pay over a two year period to Lonza approximately $34 million and an additional $19 million for resins and other raw materials required for production. We have incurred significant losses from operations to date and expect our expenses to increase in connection with our ongoing activities, and the addition of Elusys’ activities. There can be no assurance that funding will be available on acceptable terms on a timely basis, or at all.

​

Risks Related to Our Company

We have a limited operating history conducting commercial development of bioanalytics, process development and manufacturing activities, which may limit the ability of investors to make an informed investment decision.

To date, we have limited experience manufacturing products for third parties and ourselves. Because of the numerous risks and uncertainties associated with development and manufacturing, we are unable to predict if we will be successful in providing such services to ourselves or third parties. Although we plan to use our anticipated facility to service our internal manufacturing needs, we also intend to generate revenue to offset the expenses we incur in operating the facility as well as the initial start-up expenses from third parties. Our ability to generate this revenue will depend, in part, on our ability to attract and maintain customers for our development, manufacturing and technology transfer services and on the amount spent by the customers on such services. If our anticipated facility fails to attract customers and operate at sufficient capacity, our margins will suffer, and we may not be able to fund the costs we incur to operate the facility. Our bioanalytics, process development and manufacturing activities will also depend, in part, on our ability to attract and retain an appropriately skilled and sufficient workforce to operate our development and manufacturing facility and our ability to comply with various quality standards and environmental, health and safety laws and regulations.

​

We depend on spending and demand from our customers for our contract manufacturing and development services and any reduction in spending or demand could have a material adverse effect on our business.

​

The amount that our customers spend on the development and manufacture of their products or product candidates, particularly the amount our customers choose to spend on outsourcing these services to us, substantially impacts our revenue. For ANTHIM®, the U.S government’s spending budget and allocations for defense spending significantly impacts our revenue from sales of ANTHIM®. The outcomes of our customers’ research, development and marketing also significantly influence the amount that our customers choose to spend on our services and offerings. Our customers determine the amounts that they will spend on our services based upon, among other things, the clinical and market success of their products, available resources, access to capital and their need to develop new products which, in turn, depend upon a number of other factors, including their competitors’ research, development and product initiatives and the anticipated market for any new products, as well as clinical and reimbursement scenarios for specific products and therapeutic areas. Further, increasing consolidation in the pharmaceutical industry may impact such spending, particularly in the event that any of our customers choose to develop or acquire integrated manufacturing operations. Any reduction in customer spending on biologics development and related services as a result of these and other factors could have a material adverse effect on our business, financial condition, and results of operations. Available resources, the need to develop new products, and consolidation in the industries in which our customers operate may have an impact on such spending. Our customers finance their research and development spending from private and public sources. A reduction in spending by our customers, which may be influenced by the recent sharp downturn in available private and public funding for small and emerging biotechnology companies, could have a material adverse effect on our business, financial condition, and

29

results of operations. If our customers are not successful in attaining or retaining product sales due to market conditions, reimbursement issues, or other factors, our results of operations may be materially adversely affected.

​

To date, our revenues have come from a limited number of customers, making us dependent on those few customers.

​

For the year ended December 31, 2022, all of our revenue was derived from one ANTHIM® purchase order and one customer for CDMO services. Prior to our acquisition of Elusys, ANTHIM® sales were made solely by the prior management team of Elusys to U.S. Governmental agencies. If the U.S. government were to cut its healthcare spending and in particular its biodefense spending, our ability to generate revenue if we cannot compete successfully for market share against other drug companiesfrom ANTHIM® sales will be adversely impacted.

Our strategy is to expand the number of sales to such agencies as well as expand the customer base outside of the United States. To date, we have not had any experience with distribution and sales of commercial products. There can be no assurance that there will be additional demand for ANTHIM® or that we will be successful in our distribution and sale efforts Although we continue to expand our customer base, we remain dependent on a limited number of customers for a substantial majority of our revenues. The loss of, or a significant reduction of business from the U.S government for ANTHIM® or any of our current CDMO customers could have a material adverse effect on our business, financial condition, and results of operations.

​

Our ability to generate product revenues from sales of ANTHIM® is dependent upon government spending and compliance with the government contracts.

To date, substantially all of Elusys’ revenue has been derived from the sale of ANTHIM® to U.S. Governmental agencies. If the U.S. government were to cut its healthcare spending and in particular its biodefense spending, our ability to generate revenue after consummation of the Merger from ANTHIM® sales will be adversely impacted.

We generally do not have long-term CDMO customer contracts and our backlog cannot be relied upon as a future indicator of revenues.

​

We generally do not have long-term contracts with our CDMO customers, and existing contracts and purchase commitments may be canceled under certain circumstances. As a result, we are exposed to market and competitive price pressures on every order, and our agreements with customers do not provide assurance of future revenues. Our customers are not required to make minimum purchases and, in certain circumstances, may cease using our services at any time without penalty. Our backlog should not be relied on as a measure of anticipated demand or future revenue, because the orders constituting our backlog may be subject to changes in delivery schedules or cancellation without significant penalty to the customer. Any reductions, cancellations or deferrals in customer orders would negatively impact our business.

​

Elusys has been manufacturing ANTHIM® with one manufacturer.

​

To date, all ANTHIM® bulk drug substance has been manufactured by one manufacturer, Lonza, at a 5,000 liter scale pursuant to the terms of an exclusive manufacturing agreement. Elusys’ ability to manufacture additional batches of bulk drug substance will be dependent upon the slotting availability of the manufacturer. In addition, the manufacturer has decommissioned its 5,000 liter assets and therefore any further manufacturing by the manufacturer will be at a 6,000 liter scale. This new scale will require new regulatory approval from the FDA, timing of approval, if obtained, cannot be certain. In addition, there is no assurance that the bulk drug substance can be successfully manufactured at a 6,000 liter scale in a cost efficient manner.

We are substantially dependent on the success of ANTHIM®.

To date, a significant portion of our efforts and financial resources has been in the development of our product candidate, HS-110, HS-130 and PTX-35 which were our only products for which we had clinical trials. We terminated our license with respect to those products and therefore currently our only product from which we have derived revenue is ANTHIM®. Our future success depends heavily on our ability to successfully manufacture and sell ANTHIM®.

30

Table of Contents

The ANTHIM® product, although approved for commercial sale, will not be manufactured at the facility that manufactured ANTHIM® previously sold by Elusys and therefore the facility where it will be manufactured will require regulatory approval. We and our product candidates are subject to extensive regulation by the FDA and comparable regulatory authorities in other countries governing, among other things, research, testing, clinical trials, manufacturing, labeling, promotion, marketing, adverse event reporting and recordkeeping of our product candidates. Until, and unless, we receive approval from the FDA and other regulatory authorities for our product candidates, we cannot commercialize our product candidates and will not have product revenues. In addition, the technology that we out-licensed is in the early stages of development and there is a low likelihood of success for any such technology at that stage, therefore there can be no assurance that any products will be developed by such licensee or that we will derive any revenue from such licensee. In addition, changes may occur that would consume our available capital at a faster pace than expected, including changes in and progress of our development activities, acquisitions of additional candidates and changes in regulation. Moreover, preclinical studies and clinical trials may not start or be completed as we forecast and may not achieve the desired results. Therefore, we expect that we will seek additional sources of funding, such as additional financing or grant funding, and additional financing may not be available on favorable terms, if at all. Our ability to raise capital through the sale of equity may be limited by the various rules of the Securities and Exchange Commission and the NYSE American that place limits on the number of shares of stock that may be sold. If we do not succeed in raising additional funds on acceptable terms, we may be unable to complete planned preclinical work or obtain approval of our product candidates from the FDA and other regulatory authorities. In addition, we could be forced to delay, discontinue or curtail product development, forego sales and marketing efforts, and forego licensing in attractive business opportunities. Any additional sources of financing will likely involve the issuance of our equity or debt securities, which will have a dilutive effect on our stockholders.

​

All of our manufacturing services are conducted at our facility situated in San Antonio, Texas, which increases our exposure to significant disruption to our business as a result of unforeseeable developments in a single geographic area.

​

We operate one manufacturing facility in one location, San Antonio, Texas. It is possible that we could experience prolonged periods of reduced production due to unforeseen catastrophic events occurring in or around our facilities. It is also possible that operations could be disrupted due to other unforeseen circumstances such as power outages, explosions, fires, floods, earthquakes or accidents. As a result, we may be unable to shift manufacturing capabilities to alternate locations, accept materials from suppliers, meet customer shipment needs or address other severe consequences that may be encountered, and we may suffer damage to our reputation. Our financial condition and results of our operations could be materially adversely affected were such events to occur.

​

The operations of our CROs and suppliers could also be subject to business interruptions.

​

Our business and the business of the raw material suppliers could be materially and adversely affected by the risks, or the public perception of the risks, related to a pandemic or other health crisis, such as the recent outbreak of novel coronavirus (COVID-19). A significant outbreak of contagious diseases in the human population could result in a widespread health crisis that could adversely affect our planned operations. Such events could result in the complete or partial closure of one or more manufacturing facilities. In addition, it could impact economies and financial markets, resulting in an economic downturn that could impact our ability to raise capital or slow down potential partnering relationships.

We rely on third parties to supply most of the necessary raw materials and supplies for the products we manufacture on behalf of our customers and our inability to obtain such raw materials or supplies may adversely impact our business, financial condition, and results of operations.

​

Our operations require various raw materials, including proprietary media, resins, buffers, and filters, in addition to numerous additional raw materials supplied primarily by third parties. We or our customers specify the raw materials and other items required to manufacture their product and, in some cases, specify the suppliers from whom we must purchase these raw materials. In certain instances, the raw materials and other items can only be supplied by a limited number of suppliers and, in some cases, a single source, or in limited quantities. If third-party suppliers do not supply raw materials or other items on a timely basis, it may cause a manufacturing run to be delayed or canceled which would adversely impact our financial condition and results of operations. Additionally, we do not have long-term supply contracts with any of our single source suppliers. If we experience difficulties acquiring sufficient quantities of required materials or products from

31

Table of Contents

our existing suppliers, or if our suppliers are found to be non-compliant with the FDA’s quality system regulation, CGMPs or other applicable laws or regulations, we would be required to find alternative suppliers. If our primary suppliers become unable or unwilling to perform, any resulting delays or interruptions in the supply of raw materials required to support our manufacturing of CGMP pharmaceutical-grade products would ultimately delay our manufacture of products for our customers, which could materially and adversely affect our financial condition and operating results. Furthermore, third-party suppliers may fail to provide us with raw materials and other items that meet the qualifications and specifications required by us or our customers. If third-party suppliers are not able to provide us with raw materials that meet our or our customers’ specifications on a timely basis, we may be unable to manufacture their product or it could prevent us from delivering products to our customers within required timeframes. Any such delay in delivering our products may create liability for us to our customers for breach of contract or cause us to experience order cancellations and loss of customers. In the event that we manufacture products with inferior quality components and raw materials, we may become subject to product liability claims caused by defective raw materials or components from a third-party supplier or from a customer, or our customer may be required to recall its products from the market.

​

Our manufacturing services are highly complex, and if we are unable to provide quality and timely services to our customers, our business could suffer.

​

The manufacturing services we offer are highly complex, due in part to strict regulatory requirements. A failure of our quality control systems in our facility could cause problems to arise in connection with facility operations for a variety of reasons, including equipment malfunction, viral contamination, failure to follow specific manufacturing instructions, protocols and standard operating procedures, problems with raw materials or environmental factors. Such problems could affect production of a single manufacturing run or a series of runs, requiring the destruction of products, or could halt manufacturing operations altogether. In addition, our failure to meet required quality standards may result in our failure to timely deliver products to our customers which, in turn, could damage our reputation for quality and service. Any such incident could, among other things, lead to increased costs, lost revenue, reimbursement to customers for lost drug substance, damage to and possibly termination of existing customer relationships, time and expense spent investigating the cause and, depending on the cause, similar losses with respect to other manufacturing runs. With respect to our commercial manufacturing, if problems are not discovered before the product is released to the market, we may be subject to regulatory actions, including product recalls, product seizures, injunctions to halt manufacture and distribution, restrictions on our operations, civil sanctions, including monetary sanctions, and criminal actions. In addition, such issues could subject us to litigation, the cost of which could be significant.

​

Our customers’ failure to receive or maintain regulatory approval for their product candidates could negatively impact our revenues and profitability.

​

Our success depends upon the regulatory approval of the products we manufacture. As such, if our customers experience a delay in, or failure to receive, approval for any of their product candidates or fail to maintain regulatory approval of their products and we are not able to manufacture these products, our revenue and profitability could be adversely affected. Additionally, if the FDA or a comparable foreign regulatory authority does not approve of our facilities for the manufacture of a customer product or if it withdraws such approval in the future, our customers may choose to identify alternative manufacturing facilities and/or relationships, which could significantly impact our ability to expand our manufacturing capacity and capabilities and achieve profitability.

​

If we use hazardous and biological materials in a manner that causes injury or violates applicable law, we may be liable for damages.

​

Our contract manufacturing operations involve the controlled use of hazardous materials and chemicals. We are subject to federal, state and local laws and regulations in the United States governing the use, manufacture, storage, handling and disposal of hazardous materials and chemicals. Although we believe that our procedures for using, handling, storing and disposing of these materials comply with legally prescribed standards, we may incur significant additional costs to comply with applicable laws in the future. Also, even if we are in compliance with applicable laws, we cannot completely eliminate the risk of contamination or injury resulting from hazardous materials or chemicals. As a result of any such contamination or injury, we may incur liability or local, city, state or federal authorities may curtail the use of these materials and interrupt our business operations. In the event of an accident, we could be held liable for damages or penalized with fines, and the

32

Table of Contents

liability could exceed our resources. Compliance with applicable environmental laws and regulations is expensive, and current or future environmental regulations may impair our contract manufacturing operations, which could materially harm our business, financial condition and results of operations.

​

If our acquired intangible assets become impaired, we may be required to record a significant charge to earnings.

​

We regularly review acquired intangible assets for impairment when events or changes in circumstances indicate that the carrying value may not be recoverable. We test goodwill and indefinite-lived intangible assets for impairment at least annually. Factors that may be considered a change in circumstances, indicating that the carrying value of the intangible assets may not be recoverable, include: macroeconomic conditions, such as deterioration in general economic conditions; industry and market considerations, such as deterioration in the environment in which we operate; cost factors, such as increases in labor or other costs that have a negative effect on earnings and cash flows; our financial performance, such as negative or declining cash flows or a decline in actual or planned revenue or earnings compared with actual and projected results of relevant prior periods; other relevant entity-specific events, such as changes in management, key personnel, strategy, or customers; and sustained decreases in share price. During the year ended December 31, 2022 we recorded a indefinite-lived intangible assets impairment charge of $3.5 million. During the year ended December 31, 2021 we recorded a indefinite-lived intangible assets impairment charge totaling $2.4 million and goodwill impairment charge of $1.5 million.

​

Risks Related to Regulatory Approval and Commercialization

Failure to comply with existing and future regulatory requirements for our CDMO and sales of ANTHIM® could adversely affect our business, financial condition, and results of operations.

​

Our industry is highly regulated. We are required to comply with the regulatory requirements of various local, state, provincial, national and international regulatory bodies having jurisdiction in the countries or localities in which we manufacture products or in which our customers’ products are distributed. In particular, our CDMO is subject to laws and regulations concerning development, testing, manufacturing processes, equipment and facilities, including compliance with CGMPs, import and export, and product registration and listing, among other things. As a result, our facility is subject to regulation by the FDA, as well as regulatory bodies of other jurisdictions where our customers have marketing approval for their products including, but not limited to, the EMA, ANVISA and/or Health Canada, depending on the countries in which our customers market and sell the products we manufacture on their behalf. As we expand our operations, including building our facility in Kansas, we may be exposed to more complex and new regulatory and administrative requirements and legal risks, any of which may require expertise in which we have little or no experience. It is possible that compliance with new regulatory requirements could impose significant compliance costs on us. Such costs could have a material adverse effect on our business, financial condition and results of operations.

​

These regulatory requirements impact many aspects of our operations, including manufacturing, developing, storage, distribution, import and export and record keeping related to customers’ products. Noncompliance with any applicable regulatory requirements can result in government refusal to approve: (i) facilities for testing or manufacturing products or (ii) products for commercialization. The FDA and other regulatory agencies can delay, limit or deny approval for many reasons, including:

​

| ● | changes to the regulatory approval process, including new data requirements for product candidates in those jurisdictions, including the United States, in which our customers may be seeking approval;

| ● | that a customer’s product candidate may not be deemed to be safe or effective; and

| ● | the inability of the regulatory agency to provide timely responses as a result of its resource constraints;

| ● | that the manufacturing processes or facilities may not meet the applicable requirements.

​

In addition, if new legislation or regulations are enacted or existing legislation or regulations are amended or are interpreted or enforced differently, we may be required to obtain additional approvals or operate according to different manufacturing or operating standards. This may require a change in our development and manufacturing techniques or additional capital investments in our facilities. Any related costs may be significant. If we fail to comply with applicable regulatory requirements in the future, then we may be subject to warning letters and/or civil or criminal penalties and fines, suspension

33

Table of Contents

or withdrawal of regulatory approvals, product recalls, seizure of products, restrictions on the import and export of our products, debarment, exclusion, disgorgement of profits, operating restrictions and criminal prosecution and the loss of contracts and resulting revenue losses. Inspections by regulatory authorities that identify any deficiencies could result in remedial actions, production stoppages or facility closure, which would disrupt the manufacturing process and supply of product to our customers. In addition, such failure to comply could expose us to contractual and product liability claims, including claims by customers for reimbursement for lost or damaged active pharmaceutical ingredients or recall or other corrective actions, the cost of which could be significant.

​

In addition, certain products we manufacture must undergo pre-clinical and clinical evaluations relating to product safety and efficacy before they are approved as commercial therapeutic products. The regulatory authorities having jurisdiction in the countries in which our customers intend to market their products may delay or put on hold clinical trials or delay approval of a product or determine that the product is not approvable. The FDA or other regulatory agencies can delay approval of a drug if our manufacturing facility, including any newly commissioned facility, is not able to demonstrate compliance with CGMPs, pass other aspects of pre-approval inspections or properly scale up to produce commercial supplies. The FDA and comparable government authorities having jurisdiction in the countries in which we or our customers intend to market their products have the authority to withdraw product approval or suspend manufacture if there are significant problems with raw materials or supplies, quality control and assurance or the product we manufacture is adulterated or misbranded. If our manufacturing facilities and services are not in compliance with FDA and comparable government authorities, we may be unable to obtain or maintain the necessary approvals to continue manufacturing products for our customers, which would materially adversely affect our financial condition and results of operations.

​

If we do not obtain the necessary regulatory approvals in the United States and/or other countries, we will not be able to sell our product candidates.

​

We cannot assure you that we will receive the approvals necessary to commercialize any of our product candidates, including obtaining necessary approvals for the sale of ANTHIM® in light of the fact that the manufacturing of the ANTHIM® will not be at the facility that manufactured ANTHIM® previously sold by Elusys and therefore the facility where it will be manufactured will require regulatory approval. We will need FDA approval to commercialize our product candidates in the United States and approvals from the FDA-equivalent regulatory authorities in foreign jurisdictions to commercialize our product candidates in those jurisdictions. In order to obtain FDA approval of any product candidate, we must submit to the FDA a BLA, demonstrating that the product candidate is safe, pure and potent, or effective for its intended use. This demonstration requires significant research including preclinical studies, as well as clinical trials. Satisfaction of the FDA’s regulatory requirements typically takes many years, depends upon the type, complexity and novelty of the product candidate and requires substantial resources for research, development and testing. We cannot predict whether our clinical trials will demonstrate the safety and efficacy of our product candidates or if the results of any clinical trials will be sufficient to advance to the next phase of development or for approval from the FDA. We also cannot predict whether our research and clinical approaches will result in drugs or therapeutics that the FDA considers safe and effective for the proposed indications. The FDA has substantial discretion in the drug approval process. The approval process may be delayed by changes in government regulation, future legislation or administrative action or changes in FDA policy that occur prior to or during our regulatory review. Delays in obtaining regulatory approvals may:

| ● | prevent or delay commercialization of, and our ability to derive product revenues from, our product candidates; and

| ● | diminish any competitive advantages that we may otherwise believe that we hold.

Even if we comply with all FDA requests, the FDA may ultimately reject one or more of our BLAs. We may never obtain regulatory clearance for any of our product candidates. Failure to obtain FDA approval of any of our product candidates will severely undermine our business by leaving us without a saleable product, and therefore without any source of revenues, until another product candidate can be developed. There is no guarantee that we will ever be able to develop or acquire another product candidate.

In addition, the FDA may require us to conduct additional preclinical and clinical testing or to perform post-marketing studies, as a condition to granting marketing approval of a product. Regulatory approval of oncology products often requires that patients in clinical trials be followed for long periods to assess their overall survival. The results generated

34

Table of Contents

after approval could result in loss of marketing approval, changes in product labeling, and/or new or increased concerns about the side effects or efficacy of a product. The FDA has significant post-market authority, including the explicit authority to require post-market studies and clinical trials, labeling changes based on new safety information, and compliance with FDA-approved risk evaluation and mitigation strategies. The FDA’s exercise of its authority has in some cases resulted, and in the future, could result, in delays or increased costs during product development, clinical trials and regulatory review, increased costs to comply with additional post-approval regulatory requirements and potential restrictions on sales of approved products.

​

In foreign jurisdictions, we must also receive approval from the appropriate regulatory authorities before we can commercialize any vaccines. Foreign regulatory approval processes generally include all of the risks associated with the FDA approval procedures described above. There can be no assurance that we will receive the approvals necessary to commercialize our product candidates for sale outside the United States.

​

Our product candidates are in early stages of development, and therefore they will require extensive preclinical and clinical testing.

Because our product candidates are in early stages of development, they will require extensive preclinical and clinical testing. All of the products being developed by Skunkworx are in the preclinical stage of development. We cannot predict with any certainty if or when we might submit a BLA for regulatory approval for any of our product candidates or whether any such BLA will be accepted for review by the FDA, or whether any BLA will be approved upon review.

​

Even if we perform our clinical trials on any of those product candidates, we cannot be certain that their results will support our proposed indications. Success in preclinical testing and early clinical trials does not ensure that later clinical trials will be successful, and we cannot be sure that the results of later clinical trials will replicate the results of prior clinical trials and preclinical testing. The clinical trial process may fail to demonstrate that our product candidates are safe and effective for their proposed uses. This failure could cause us to abandon a product candidate and may delay development of other product candidates. Any delay in, or termination of, our clinical trials will delay and possibly preclude the filing of any BLAs with the FDA and, ultimately, our ability to commercialize our product candidates and generate product revenues.

​

Clinical trials are very expensive, time-consuming, and difficult to design and implement.

As part of the regulatory process, we must conduct clinical trials for each product candidate to demonstrate safety and efficacy to the satisfaction of the FDA and other regulatory authorities. The number and design of the clinical trials that will be required varies depending upon product candidate, the condition being evaluated and the trial results themselves. Therefore, it is difficult to accurately estimate the cost of the clinical trials. Clinical trials are very expensive and difficult to design and implement, in part because they are subject to rigorous regulatory requirements. The clinical trial process is also time consuming. We estimate that clinical trials of our product candidates will take at least several years to complete. Furthermore, failure can occur at any stage of the trials, and we could encounter problems that cause us to abandon or repeat clinical trials. The commencement and completion of clinical trials may be delayed or prevented by several factors, including:

| ● | unforeseen safety issues;

| ● | failure to determine appropriate dosing;

| ● | greater than anticipated cost of our clinical trials;

| ● | failure to demonstrate effectiveness during clinical trials;

| ● | slower than expected rates of patient recruitment or difficulty obtaining investigators;

| ● | patient drop-out or discontinuation;

| ● | inability to monitor patients adequately during or after treatment;

| ● | third party contractors failing to comply with regulatory requirements or meet their contractual obligations to us in a timely manner;

| ● | insufficient or inadequate supply or quality of product candidates or other necessary materials to conduct our trials;

| ● | potential additional safety monitoring, or other conditions required by FDA or comparable foreign regulatory authorities regarding the scope or design of our clinical trials, or other studies requested by regulatory agencies;

35

Table of Contents

| ● | problems engaging IRBs to oversee trials or in obtaining and maintaining IRB approval of studies;

| ● | imposition of clinical hold or suspension of our clinical trials by regulatory authorities; and

| ● | inability or unwillingness of medical investigators to follow our clinical protocols.

In addition, we or the FDA may suspend or terminate our clinical trials at any time if it appears that we are exposing participants to unacceptable health risks or if the FDA finds deficiencies in our IND submissions or the conduct of these trials. Therefore, we cannot predict with any certainty when, if ever, future clinical trials will commence or be completed.

There is uncertainty as to market acceptance of our technology and product candidates.

There can be no assurance that ANTHIM® or any product we develop in the future, even if approved by the FDA will gain broad market acceptance among governments, physicians, healthcare payers, patients, and the medical community. In addition, there can be no assurance that our CDMO services will gain market acceptance. We have conducted our own research into the markets for ANTHIM® and CDMO services generally; however, we cannot guarantee market acceptance. Our industry is susceptible to rapid technological developments and there can be no assurance that we will be able to match any new technological advances. If we are unable to match the technological changes in the needs of our customers the demand for our products will be reduced. Acceptance and use of any products or services we market will depend upon a number of factors including:

| ● | perceptions by members of the health care community, including physicians, about the safety and effectiveness of our products;

| ● | limitation on use or warnings required by FDA in our product labeling;

| ● | cost-effectiveness of our products relative to competing products;

| ● | convenience and ease of administration;

| ● | potential advantages of alternative treatment methods;

| ● | availability of reimbursement for our products from government or other healthcare payers; and

| ● | effectiveness of marketing and distribution efforts by us and our licensees and distributors, if any.

Because we expect virtually all of our product revenues for the foreseeable future to be generated from sales of our current product candidates, if approved, the failure of these therapeutics to find market acceptance would substantially harm our business and would adversely affect our revenue.

If we cannot compete successfully for market share against other drug companies, we may not achieve sufficient product revenues and our business will suffer.

The market for our product candidates is characterized by intense competition and rapid technological advances. ANTHIM® competes with one other Anthrax therapeutic, the manufacturer of which is larger than we are and has more resources to enable it to market its product. If any of our product candidates receives FDA approval, it will compete with a number of existing and future drugs and therapies developed, manufactured and marketed by others. Existing or future competing products may provide greater therapeutic convenience or clinical or other benefits for a specific indication than our products or may offer comparable performance at a lower cost. If our products fail to capture and maintain market share, we may not achieve sufficient product revenues and our business will suffer. Our CDMO competes for customers with several other CDMOs that are well established and have a longer operating history than our company.

We will compete against fully integrated pharmaceutical companies and smaller companies that are collaborating with larger pharmaceutical companies, academic institutions, government agencies and other public and private research organizations. In addition, many of these competitors, either alone or together with their collaborative partners, operate larger research and development programs or have substantially greater financial resources than we do, as well as significantly greater experience in:

| ● | developing drugs, biologics and other therapies;

| ● | undertaking preclinical testing and clinical trials;

| ● | obtaining FDA and other regulatory approvals of drugs, biologics and other therapies;

36

Table of Contents

| ● | formulating and manufacturing drugs, biologics and other therapies; and

| ● | launching, marketing and selling drugs, biologics and other therapies.

Our development program partially depends upon third-party researchers who are outside our control.

We are dependent upon independent investigators and collaborators, such as universities and medical institutions, to conduct our clinical trials under agreements with us. These collaborators are not our employees and we cannot control the amount or timing of resources that they devote to our programs. These investigators may not assign as great a priority to our programs or pursue them as diligently as we would if we were undertaking such programs ourselves. If outside collaborators fail to devote sufficient time and resources to our development programs, or if their performance is substandard, the approval of our FDA applications, if any, and our introduction of new product candidates, if any, will be delayed if obtained at all. These collaborators may also have relationships with other commercial entities, some of whom may compete with us. If our collaborators assist our competitors at our expense, our competitive position would be harmed.

We rely significantly on third parties to formulate and manufacture our product candidates.

We have developed certain expertise in the formulation, development and/or manufacturing of biologics; however to date we have relied on third parties for substantially all of our manufacturing needs. We have performed assay development work at our Texas laboratory to support our clinical needs as well as those of third parties. However, Scorpius does not have FDA approval to manufacture commercial quantities of ANTHIM®. Although there are other manufacturers that could manufacture ANTHIM®, including the manufacturer that to date has manufactured ANTHIM® and with whom we have an agreement to manufacture future batches of ANTHIM®, it will be several years before that manufacturer can manufacture ANTHIM® for us. To date, the manufacturer has only manufactured ANTHIM® at a 5,000 liter scale and the manufacturer plans to manufacture at a 6,000 liter scale at a new facility. In addition, there is no assurance that the bulk drug substance can be successfully manufactured at a 6,000 liter scale in a cost efficient manner.

Therefore, future manufacture of ANTHIM® by such manufacturer will require additional regulatory approvals for the new manufacturing site and new scale. Our anticipated future reliance on a limited number of third-party manufacturers exposes us to the following risks:

| ● | We may be unable to renew or renegotiate current agreements on favorable terms or identify manufacturers on acceptable terms or at all because the number of potential manufacturers with appropriate expertise and facilities is limited.

| ● | If we change manufacturers at any point during the development process or after approval we will be required to demonstrate comparability between the products made by the old and new manufacturers. If we are unable to do so, we may need to conduct additional clinical trials with product manufactured by the new manufacturer. Accordingly, it may be necessary to evaluate the comparability of our product candidates produced by the two different manufacturers at some point during the clinical development process.

| ● | If we change the manufacturer of a product subsequent to the approval of the product, we will need to obtain approval from the FDA of the change in manufacturer. Any such approval would likely require significant testing and expense, and the new manufacturer may be subject to a cGMP inspection prior to approval. Our third-party manufacturers might be unable to formulate and manufacture our product candidates in the volume and with the quality required to meet our clinical needs and commercial needs, if any.

| ● | Our third-party manufacturers might be unable to formulate and manufacture our product candidates in the volume and with the quality required to meet our clinical needs and commercial needs, if any.

| ● | Our contract manufacturers may not perform as agreed or may not remain in the contract manufacturing business for the time required to supply our clinical trials or to successfully produce, store and distribute our product candidates.

37

Table of Contents

| ● | Drug manufacturers are subject to ongoing periodic unannounced inspection by the FDA, and corresponding state agencies to ensure compliance with cGMPs and other government regulations and corresponding foreign standards. We do not have control over third-party manufacturers’ compliance with these regulations and standards.

| ● | If any third-party manufacturer makes improvements in the manufacturing process for our products, we may not own, or may have to share, the intellectual property rights to the innovation.

| ● | Our contract manufacturers have in the past and may in the future encounter difficulties in achieving quality control and quality assurance and may experience shortages in qualified personnel. Our contract manufacturers are subject to inspections by the FDA and comparable agencies in other jurisdictions to assess compliance with applicable regulatory requirements. Any failure to follow cGMP or other regulatory requirements or delay, interruption or other issues that arise in the manufacture, packaging, or storage of our products as a result of a failure of the facilities or operations of third parties to comply with regulatory requirements or pass any regulatory authority inspection could significantly impair our ability to develop and commercialize our products, including leading to significant delays in the availability of products for our clinical studies or the termination or hold on a clinical study, or the delay or prevention of a filing or approval of marketing applications for our product candidates. Significant noncompliance could also result in the imposition of sanctions, including fines, injunctions, civil penalties, failure of regulatory authorities to grant marketing approvals for our product candidates, delays, suspension or withdrawal of approvals, license revocation, seizures or recalls of products, operating restrictions and criminal prosecutions, any of which could damage our reputation. If we or our contract manufacturers are not able to maintain regulatory compliance, we may not be permitted to market our products and/or may be subject to product recalls, seizures, injunctions, or criminal prosecution.

​

| ● | If we establish in-house development and manufacturing capabilities, there are a number of risks that could impact our financial condition, operating results and cash flows due to disruption of operations at the location or facility which may impede our ability to deliver assays or manufacture our products.

​

Each of these risks could delay our clinical trials, the approval, if any, of our product candidates by the FDA or the commercialization of our product candidates or could also result in higher costs or deprive us of potential product revenues.

​

We have and will in the future rely on third parties to conduct, supervise and monitor any clinical trials we may conduct, and if those third parties perform in an unsatisfactory manner, it may harm our business.

We have in the past and will in the future rely on CROs and clinical trial sites to ensure the proper and timely conduct of our clinical trials, and we expect to have limited influence over their actual performance if we should conduct any future clinical trials.

We also expect to rely upon CROs to monitor and manage data for any future clinical programs we may have, as well as the execution of future nonclinical studies. We expect to control only certain aspects of our CROs’ activities. Nevertheless, we will be responsible for ensuring that each of our studies we may conduct is conducted in accordance with the applicable protocol, legal, regulatory and scientific standards and our reliance on the CROs does not relieve us of our regulatory responsibilities.

We and our CROs will be required to comply with the Good Laboratory Practices and GCPs, which are regulations and guidelines enforced by the FDA and are also required by the Competent Authorities of the Member States of the European Economic Area and comparable foreign regulatory authorities in the form of International Conference on Harmonization of Technical Requirements for Pharmaceuticals for Human Use guidelines for any of our product candidates that are in preclinical and clinical development. The Regulatory authorities enforce GCPs through periodic inspections of trial sponsors, principal investigators and clinical trial sites. If we or our CROs fail to comply with GCPs, the clinical data generated in any clinical trials may be deemed unreliable and the FDA or comparable foreign regulatory authorities may require us to perform additional clinical trials before approving our marketing applications. Accordingly, if our CROs fail to comply with these regulations or fail to recruit a sufficient number of subjects, we may be required to repeat clinical trials, which would delay the regulatory approval process.

Table of Contents

Our CROs will not be our employees, and we will not control whether or not they devote sufficient time and resources to our future clinical and nonclinical programs. These CROs may also have relationships with other commercial entities, including our competitors, for whom they may also be conducting clinical trials, or other drug development activities which could harm our competitive position. We face the risk of potential unauthorized disclosure or misappropriation of our intellectual property by CROs, which may reduce our trade secret protection and allow our potential competitors to access and exploit our proprietary technology. If our CROs do not successfully carry out their contractual duties or obligations, fail to meet expected deadlines, or if the quality or accuracy of the clinical data they obtain is compromised due to the failure to adhere to our clinical protocols or regulatory requirements or for any other reasons, our clinical trials may be extended, delayed or terminated, and we may not be able to obtain regulatory approval for, or successfully commercialize any product candidate that we develop. As a result, our financial results and the commercial prospects for any product candidate that it develops would be harmed, its costs could increase, and our ability to generate revenues could be delayed.

If our relationship with these CROs terminate, we may not be able to enter into arrangements with alternative CROs or do so on commercially reasonable terms. Switching or adding additional CROs involves substantial cost and requires management time and focus. In addition, there is a natural transition period when a new CRO commences work. As a result, delays occur, which can materially impact our ability to meet our desired clinical development timelines. Though we intend to carefully manage our relationships with our CROs, there can be no assurance that it will not encounter challenges or delays in the future or that these delays or challenges will not have an adverse impact on our business, financial condition and prospects.

Even if we are able to obtain regulatory approval for our product candidates, we will continue to be subject to ongoing and extensive regulatory requirements, and our failure, or the failure of our contract manufacturers, to comply with these requirements could substantially harm our business.

If the FDA approves any of our product candidates, the labeling, manufacturing, packaging, adverse event reporting, storage, advertising, promotion and record keeping for our products will be subject to ongoing FDA requirements and continued regulatory oversight and review. As stated above, our manufacture of ANTHIM® will require additional regulatory approval. We may also be subject to additional FDA post-marketing obligations. If we are not able to maintain regulatory compliance, we may not be permitted to market our product candidates and/or may be subject to product recalls or seizures. The subsequent discovery of previously unknown problems with any marketed product, including AEs of unanticipated severity or frequency, may result in restrictions on the marketing of the product, and could include withdrawal of the product from the market.

We have minimal experience selling, marketing or distributing products, and have no internal capability to do so.

To date, we have not had any significant sales, marketing or distribution capabilities. Although we have hired some of the Elusys employees who have such experience and Scorpius has hired sales representatives, we do not anticipate having the resources in the foreseeable future to allocate to the sales and marketing of our other proposed products, if approved. Our future success depends, in part, on our ability to enter into and maintain collaborative relationships for such capabilities, the collaborator’s strategic interest in ANTHIM® and the products under development and such collaborator’s ability to successfully market and sell any such products. We intend to pursue collaborative arrangements regarding the sales and marketing of our products, however, there can be no assurance that we will be able to establish or maintain such collaborative arrangements, or if able to do so, that our collaborators will have effective sales forces. To the extent that we decide not to, or are unable to, enter into collaborative arrangements with respect to the sales and marketing of our proposed products, significant capital expenditures, management resources and time will be required to establish and develop an in-house marketing and sales force with technical expertise. There can also be no assurance that we will be able to establish or maintain relationships with third party collaborators or develop in-house sales and distribution capabilities. To the extent that we depend on third parties for marketing and distribution, any revenues we receive will depend upon the efforts of such third parties, and there can be no assurance that such efforts will be successful. In addition, there can also be no assurance that we will be able to successfully market and sell our products in the United States or overseas on our own.

We may not be successful in establishing and maintaining strategic partnerships, which could adversely affect our ability to develop and commercialize products.

We may seek to enter into strategic partnerships in the future, including alliances with other biotechnology or pharmaceutical companies, to enhance and accelerate the development and commercialization of our products. We face significant competition in seeking appropriate strategic partners and the negotiation process is time-consuming and complex. Moreover, we may not be successful in our efforts to establish a strategic partnership or other alternative arrangements for any future product candidates and programs because our research and development pipeline may be insufficient, our product candidates and programs may be deemed to be at too early of a stage of development for collaborative effort and/or third parties may not view our product candidates and programs as having the requisite potential to demonstrate safety and efficacy or return on investment. Even if we are successful in our efforts to establish strategic partnerships, the terms that we agree upon may not be favorable to us and we may not be able to maintain such strategic partnerships if, for example, development or approval of a product candidate is delayed or sales of an approved product are disappointing.

If we ultimately determine that entering into strategic partnerships is in our best interest, but either fail to enter into, are delayed in entering into or fail to maintain such strategic partnerships:

| ● | the development of certain of our current or future product candidates may be terminated or delayed;

| ● | our cash expenditures related to development of certain of our current or future product candidates may increase significantly and we may need to seek additional financing;

| ● | we may be required to hire additional employees or otherwise develop expertise, such as sales and marketing expertise, for which we have not budgeted;

| ● | we will bear all of the risk related to the development of any such product candidates; and

| ● | the competitiveness of any product candidate that is commercialized could be reduced.

To the extent we elect to enter into licensing or collaboration agreements to partner our product candidates, our dependence on such relationships may adversely affect our business.

Our commercialization strategy for certain of our product candidates may depend on our ability to enter into agreements with collaborators to obtain assistance and funding for the development and potential commercialization of these product candidates. Supporting diligence activities conducted by potential collaborators and negotiating the financial and other terms of a collaboration agreement are long and complex processes with uncertain results. Even if we are successful in entering into one or more collaboration agreements, collaborations may involve greater uncertainty for us, as we have less control over certain aspects of our collaborative programs than we do over our proprietary development and commercialization programs. We may determine that continuing collaboration under the terms provided is not in our best interest, and we may terminate the collaboration. Our collaborators could delay or terminate their agreements, and our product candidates subject to collaborative arrangements may never be successfully developed or commercialized.

Further, our future collaborators may develop alternative products or pursue alternative technologies either on their own or in collaboration with others, including our competitors, and the priorities or focus of our collaborators may shift such that our programs receive less attention or fewer resources than we would like, or they may be terminated altogether. Any such actions by our collaborators may adversely affect our business prospects and ability to earn revenues. In addition, we could have disputes with our future collaborators, such as the interpretation of terms in our agreements. Any such disagreements could lead to delays in the development or commercialization of any potential products or could result in time-consuming and expensive litigation or arbitration, which may not be resolved in our favor.

Our ability to generate product revenues will be diminished if our products sell for inadequate prices or patients are unable to obtain adequate levels of reimbursement.

Our ability to commercialize our products, alone or with collaborators, will depend in part on the extent to which reimbursement will be available from:

| ● | government and health administration authorities;

40

Table of Contents

| ● | private health maintenance organizations and health insurers; and

| ● | other healthcare payers.

Significant uncertainty exists as to the reimbursement status of newly approved healthcare products. Healthcare payers, including Medicare, are challenging the prices charged for medical products and services. Cost control initiatives could decrease the price that we would receive for any products in the future, which would limit our revenue and profitability. Government and other healthcare payers increasingly attempt to contain healthcare costs by limiting both coverage and the level of reimbursement for drugs and therapeutics. We might need to conduct post-marketing studies in order to demonstrate the cost-effectiveness of any future products to such payers’ satisfaction. Such studies might require us to commit a significant amount of management time and financial and other resources. Our future products might not ultimately be considered cost-effective. Even if one of our product candidates is approved by the FDA, insurance coverage may not be available, and reimbursement levels may be inadequate, to cover such therapies. If government and other healthcare payers do not provide adequate coverage and reimbursement levels for one of our products, once approved, market acceptance of such product could be reduced.

Legislative and regulatory changes affecting the health care industry could adversely affect our business.

Political, economic and regulatory influences are subjecting the health care industry to potential fundamental changes that could substantially affect our results of operations. In many countries, the government controls the pricing and profitability of prescription pharmaceuticals. In the United States, we expect that there will continue to be federal and state proposals to implement similar governmental controls. In addition, recent changes in the Medicare program and increasing emphasis on managed care in the United States will continue to put pressure on pharmaceutical product pricing. It is uncertain whether or when any legislative proposals will be adopted or what actions federal, state, or private payers for health care treatment and services may take in response to any health care reform proposal or legislation. We cannot predict the effect health care reforms may have on our business and we can offer no assurances that any of these reforms will not have a material adverse effect on our business. These actual and potential changes are causing the marketplace to put increased emphasis on the delivery of more cost-effective treatments. In addition, uncertainly remains regarding proposed significant reforms to the U.S. health care system.

In the United States and some foreign jurisdictions, there have been a number of legislative and regulatory changes and proposed changes regarding the healthcare system that could, among other things, prevent or delay marketing approval of our clinical product candidate, restrict or regulate post-approval activities and affect our ability to profitably sell any product candidate for which we obtain marketing approval. Changes in regulations, statutes or the interpretation of existing regulations could impact our business in the future by requiring, for example: (i) changes to our manufacturing arrangements, (ii) additions or modifications to product labeling, (iii) the recall or discontinuation of our products or (iv) additional record-keeping requirements. If any such changes were to be imposed, they could adversely affect our business, financial condition and results of operations.

Among policy makers in the United States and elsewhere, there is significant interest in promoting changes in healthcare systems with the stated goals of containing healthcare costs, improving quality and/or expanding access. In the United States, the pharmaceutical industry has been a particular focus of these efforts and has been significantly affected by major legislative initiatives. In March 2010, The Patient Protection and Affordable Care Act (ACA), was passed, which substantially changed the way healthcare is financed by both the government and private insurers, and significantly impacts the U.S. pharmaceutical industry. The ACA, among other things, subjects biological products to potential competition by lower-cost biosimilars, addresses a new methodology by which rebates owed by manufacturers under the Medicaid Drug Rebate Program are calculated for drugs that are inhaled, infused, instilled, implanted or injected, increases the minimum Medicaid rebates owed by manufacturers under the Medicaid Drug Rebate Program and extends the rebate program to individuals enrolled in Medicaid managed care organizations, establishes annual fees and taxes on manufacturers of certain branded prescription drugs, and creates a new Medicare Part D coverage gap discount program, in which manufacturers must agree to offer 70% point-of-sale discounts off negotiated prices of applicable brand drugs to eligible beneficiaries during their coverage gap period, as a condition for the manufacturer’s outpatient drugs to be covered under Medicare Part D.

41

Table of Contents

Some of the provisions of the ACA have yet to be fully implemented, while certain provisions have been subject to judicial and Congressional challenges. It is unclear how these challenges and other efforts to replace the ACA will impact our business in the future.

Moreover, the Drug Supply Chain Security Act imposes obligations on manufacturers of prescription drugs in finished dosage forms. We have not yet adopted the significant measures that will be required to comply with this law. We are not sure whether additional legislative changes will be enacted, or whether the current regulations, guidance or interpretations will be changed, or what the impact of such changes on our business, if any, may be.

There have been, and likely will continue to be, legislative and regulatory proposals at the foreign, federal and state levels directed at broadening the availability of healthcare and containing or lowering the cost of healthcare. The implementation of cost containment measures or other healthcare reforms may prevent us from being able to generate revenue, attain profitability, or commercialize our products. Such reforms could have an adverse effect on anticipated revenue from product candidates that we may successfully develop and for which we may obtain regulatory approval and may affect our overall financial condition and ability to develop product candidates.

We expect that additional state and federal healthcare reform measures will be adopted in the future, any of which could limit the amounts that federal and state governments will pay for healthcare products, which could result in reduced demand for our clinical product candidate or additional pricing pressures. Any reduction in reimbursement from Medicare or other government programs may result in a similar reduction in payments from private payors.

We may be exposed to liability claims associated with the use of biological and hazardous materials and chemicals.

Our research and development activities and CDMO services we provide may involve the controlled use of biological and hazardous materials and chemicals. Although we believe that our safety procedures for using, storing, handling and disposing of these materials comply with federal, state and local laws and regulations, we cannot completely eliminate the risk of accidental injury or contamination from these materials. We currently operate one laboratory in North Carolina, one laboratory in New Jersey and Pelican operates a laboratory in Texas. In our laboratory in Texas, we will perform contract services for third parties that could involve the use of biological and hazardous materials and chemicals. In the event of such an accident, we could be held liable for any resulting damages and any liability could materially adversely affect our business, financial condition and results of operations. In addition, the federal, state and local laws and regulations governing the use, manufacture, storage, handling and disposal of hazardous or radioactive materials and waste products may require us to incur substantial compliance costs that could materially adversely affect our business, financial condition and results of operations.

We may incur substantial liabilities and may be required to limit commercialization of our products in response to product liability lawsuits.

The testing and marketing of drug and biological product candidates entail an inherent risk of product liability. Product liability claims might be brought against us by consumers, health care providers or others selling or otherwise coming into contact with our products. We currently operate one laboratory in North Carolina, one laboratory in New Jersey and Pelican operates a laboratory in Texas. In our laboratory in Texas we perform contract services for third parties. In addition, in our facility in San Antonio we perform CDMO services for third parties. We could incur liability in the performance of these services, including liability for damage to materials supplied to us. If any of the products or services we develop are used in clinical trials, clinical trial liability claims may be filed against us for damages suffered by clinical trial subjects or their families. If we cannot successfully defend ourselves against product liability claims, we may incur substantial liabilities or be required to limit commercialization of our products which could impact our ability to continue as a going concern. Our inability to obtain sufficient product liability insurance at an acceptable cost to protect against potential product liability claims could prevent or inhibit the commercialization of pharmaceutical products we develop, alone or with collaborators. In addition, regardless of merit or eventual outcome, product liability claims may result in:

| ● | decreased demand for any approved product candidates;

| ● | impairment of our business reputation;

| ● | withdrawal of clinical trial participants;

42

Table of Contents

| ● | costs of related litigation;

| ● | distraction of management’s attention;

| ● | substantial monetary awards to patients or other claimants;

| ● | loss of revenues; and

| ● | the inability to successfully commercialize any approved drug candidates.

International expansion of our business exposes us to business, regulatory, political, operational, financial and economic risks associated with doing business outside of the United States.

Our business strategy incorporates international expansion, including establishing and maintaining clinician marketing and education capabilities outside of the United States, expanding our relationships with distributors and manufacturers and expanding sales of ANTHIM®. Doing business internationally involves a number of risks, including:

| ● | multiple, conflicting and changing laws and regulations such as tax laws, export and import restrictions, employment laws, regulatory requirements and other governmental approvals, permits and licenses;

| ● | failure by us or our distributors to obtain regulatory approvals for the sale or use of our product candidates in various countries;

| ● | difficulties in managing foreign operations;

| ● | complexities associated with managing multiple payer-reimbursement regimes or self-pay systems;

| ● | limits on our ability to penetrate international markets if our product candidates cannot be processed by a manufacturer appropriately qualified in such markets;

| ● | financial risks, such as longer payment cycles, difficulty enforcing contracts and collecting accounts receivable and exposure to foreign currency exchange rate fluctuations;

| ● | reduced protection for intellectual property rights;

| ● | natural disasters, political and economic instability, including wars, terrorism and political unrest, outbreak of disease, boycotts, curtailment of trade and other business restrictions; and

| ● | failure to comply with the Foreign Corrupt Practices Act, including its books and records provisions and its anti-bribery provisions, by maintaining accurate information and control over sales and distributors’ activities.

Any of these risks, if encountered, could significantly harm our future international expansion and operations and, consequently, have a material adverse effect on our financial condition, results of operations and cash flows.

We may acquire other businesses or form joint ventures or make investments in other companies or technologies or new lines of business that could harm our operating results, dilute our stockholders’ ownership, increase our debt or cause us to incur significant expense.

As part of our business strategy, we may pursue acquisitions of businesses and assets, such as we did with Pelican and Elusys. We may also make investments in other companies of technologies, new lines of business, or expansion of research bioanalytical development and manufacturing capacities. We also may pursue strategic alliances and joint ventures that leverage our core technology and industry experience to expand our offerings or distribution. Other than our acquisition of the equity of Pelican in 2017 and acquisition of Elusys in 2022, we have no experience with acquiring other companies and limited experience with forming strategic alliances and joint ventures. We may not be able to find suitable partners or acquisition candidates, and we may not be able to complete such transactions on favorable terms, if at all. If we make any acquisitions, we may not be able to integrate these acquisitions successfully into our existing business, and we could assume unknown or contingent liabilities. Any future acquisitions or investments in other companies or technologies or new lines of business also could result in significant write-offs or the incurrence of debt and contingent liabilities, any of which could have a material adverse effect on our financial condition, results of operations and cash flows. Integration of an acquired company also may disrupt ongoing operations and require management resources that would otherwise focus on developing our existing business. We may experience losses related to investments in other companies, which could have a material negative effect on our results of operations. We may not identify or complete these transactions in a timely manner, on a cost-effective basis, or at all, and we may not realize the anticipated benefits of any acquisition, technology license, strategic alliance or joint venture.

43

Table of Contents

To finance any acquisitions or joint ventures, we may choose to issue shares of our common stock as consideration, which would dilute the ownership of our stockholders. If the price of our common stock is low or volatile, we may not be able to acquire other companies or fund a joint venture project using our stock as consideration. Alternatively, it may be necessary for us to raise additional funds for acquisitions through public or private financings. Additional funds may not be available on terms that are favorable to us, or at all.

Uncertainty regarding health care reform and declining general economic or business conditions may have a negative impact on our business.

Continuing concerns over U.S. health care reform legislation and energy costs, geopolitical issues, the availability and cost of credit and government stimulus programs in the United States and other countries have contributed to increased volatility and diminished expectations for the global economy. If the economic climate does not improve or continues to be uncertain, our business, as well as the financial condition of our suppliers and our third-party payors, could be adversely affected, resulting in a negative impact on our business, financial condition and results of operations.

We rely extensively on our information technology systems and are vulnerable to damage and interruption.

We rely on our information technology systems and infrastructure to process transactions, summarize results and manage our business, including maintaining client and supplier information. Additionally, we utilize third parties, including cloud providers, to store, transfer and process data. Our information technology systems, as well as the systems of our suppliers and other partners, whose systems we do not control, are vulnerable to outages and an increasing risk of continually evolving deliberate intrusions to gain access to company sensitive information. Likewise, data security incidents and breaches by employees and others with or without permitted access to our systems pose a risk that sensitive data may be exposed to unauthorized persons or to the public. A cyber-attack or other significant disruption involving our information technology systems, or those of our vendors, suppliers and other partners, could also result in disruptions in critical systems, corruption or loss of data and theft of data, funds or intellectual property. We may be unable to prevent outages or security breaches in our systems. We remain potentially vulnerable to additional known or yet unknown threats as, in some instances, we, our suppliers and our other partners may be unaware of an incident or its magnitude and effects. We also face the risk that we expose our vendors or partners to cybersecurity attacks. Any or all of the foregoing could adversely affect our results of operations and our business reputation.

Any failure to maintain the security of information relating to our customers, employees and suppliers, whether as a result of cybersecurity attacks or otherwise, could expose us to litigation, government enforcement actions and costly response measures, and could disrupt our operations and harm our reputation. We are a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to smaller reporting companies will make our common stock less attractive to investors.

In connection with the sales and marketing of our products and services, we may from time to time transmit confidential information. We also have access to, collect or maintain private or confidential information regarding our clinical trials and the patients enrolled therein, employees, and suppliers, as well as our business. Cyberattacks are rapidly evolving and becoming increasingly sophisticated. In addition, as the manufacturer of biodefense product sold to the U.S. government, Elusys has access to highly confidential government information. It is possible that computer hackers and others might compromise our security measures, or security measures of those parties that we do business with now or in the future and obtain the personal information of patients in our clinical trials, vendors, employees and suppliers or our business information. A security breach of any kind, including physical or electronic break-ins, computer viruses and attacks by hackers, employees or others, could expose us to risks of data loss, litigation, government enforcement actions, regulatory penalties and costly response measures, and could seriously disrupt our operations. Any resulting negative publicity could significantly harm our reputation, which could cause us to lose market share and have an adverse effect on our results of operations.

We may face particular data protection, data security and privacy risks in connection with the European Union’s Global Data Protection Regulation and other privacy regulations.

Outside of the United States, the laws, regulations and standards in many jurisdictions apply broadly to the collection, use, and other processing of personal information. If we should engage in business in the European Union, including selling products such as ANTHIM®, we will be subject to such laws. For example, in the European Union, the collection and use of personal data is governed by the provisions of the General Data Protection Regulation (the “GDPR”). The GDPR, together with national legislation, regulations and guidelines of the European Union member states governing the processing of personal data, impose strict obligations on entities subject to the GDPR, including but not limited to: (i) accountability and transparency requirements, and enhanced requirements for obtaining valid consent from data subjects; (ii) obligations to consider data protection as any new products or services are developed and to limit the amount of personal data processed; (iii) obligations to comply with the data protection rights of data subjects; and (iv) obligations to report certain personal data breaches to governmental authorities and individuals. Data protection authorities from the different E.U. member states and other European countries may enforce the GDPR and national data protection laws differently, and introduce additional national regulations and guidelines, which adds to the complexity of processing European personal data. Failure to comply with the requirements of the GDPR and the related national data protection laws may result in significant monetary fines and other administrative penalties (the GDPR authorizes fines for certain violations of up to 4% of global annual revenue or €20 million, whichever is greater) as well as civil liability claims from individuals whose personal data was processed. Additionally, expenses associated with compliance could reduce our operating margins.

The GDPR also prohibits the transfer of personal data from the E.U. to countries outside of the E.U. unless made to a country deemed by the European Commission to provide adequate protection for personal data or accomplished by means of an approved data transfer mechanism (e.g., standard contractual clauses). Data protection authority guidance and enforcement actions that restrict companies’ ability to transfer data may increase risk relating to data transfers or make it more difficult or impossible to transfer E.U. personal data to the U.S.

​

Our operating results may be adversely affected by fluctuations in foreign currency exchange rates and restrictions on the deployment of cash across global operations.

​

Although we report operating results in U.S. dollars, if we engage in sales of products internationally, our revenues and expenses are or will be denominated in currencies other than the U.S. dollar, particularly in Europe. Fluctuations in foreign currency exchange rates can have a number of adverse effects on us. Because our consolidated financial statements are presented in U.S. dollars, we will be required to translate revenues, expenses and income, as well as assets and liabilities, into U.S. dollars at exchange rates in effect during or at the end of each reporting period. Therefore, changes in the value of the U.S. dollar against other currencies will affect revenues, income from operations, other income (expense), net and the value of balance sheet items originally denominated in other currencies. There is no guarantee that our financial results will not be adversely affected by currency exchange rate fluctuations. In addition, in some countries we could be subject to strict restrictions on the movement of cash and the exchange of foreign currencies, which could limit our ability to use these funds across our global operations.

​

We could be adversely affected by violations of the U.S. Foreign Corrupt Practices Act and other worldwide anti-bribery laws.

​

The FCPA and anti-bribery laws in other jurisdictions generally prohibit companies and their intermediaries from making improper payments for the purpose of obtaining or retaining business or other commercial advantage. Our policies mandate compliance with these anti-bribery laws, which often carry substantial penalties, including criminal and civil fines, potential loss of export licenses, possible suspension of the ability to do business with the federal government, denial of government reimbursement for products and exclusion from participation in government health care programs. We may operate in jurisdictions that have experienced governmental and private sector corruption to some degree, and, in certain circumstances, strict compliance with anti-bribery laws may conflict with certain local customs and practices. We cannot assure that the internal control policies and procedures always will protect us from reckless or other inappropriate acts committed by affiliates, employees or agents. Violations of these laws, or allegations of such violations, could have a material adverse effect on our business, financial position and results of operations.

Risks Related to Intellectual Property

We have limited protection for our intellectual property, which could impact our competitive position.

We intend to rely on a combination of common law copyright, patent, trademark, and trade secret laws and measures to protect our proprietary information. We have obtained exclusive rights to license the technology for which patent protection has been obtained; however, such protection does not prevent unauthorized use of such technology Trademark and copyright protections may be limited, and enforcement could be too costly to be effective. It may also be possible for unauthorized third parties to copy aspects of, or otherwise obtain and use, our proprietary information without authorization, including, but not limited to, product design, software, customer and prospective customer lists, trade secrets, copyrights, patents and other proprietary rights and materials. Other parties can use and register confusingly similar business, product and service names, as well as domain names, which could divert customers, resulting in a material adverse effect on our business, operating results and financial condition.

Intellectual property rights may also be unavailable or limited in some foreign countries, which could make it easier for competitors to capture market share. Many companies have encountered significant problems in protecting and defending intellectual property rights in foreign jurisdictions. The legal systems of certain countries, particularly certain developing countries, do not favor the enforcement of patents, trade secrets and other intellectual property protection, particularly those relating to biotechnology products, which could make it difficult for us to stop the infringement of our patents or marketing of competing products in violation of our proprietary rights generally. Many countries have compulsory licensing laws under which a patent owner may be compelled to grant licenses to third parties. As a result, in response to the COVID-19 pandemic, it is possible that certain countries may take steps to facilitate compulsory licenses that permit the distribution of a COVID-19 vaccine in those countries. In addition, many countries limit the enforceability of patents against government agencies or government contractors. In these countries, the patent owner may have limited remedies, which could materially diminish the value of the relevant patent rights. If we or any of our licensors is forced to grant a license to third parties with respect to any patents relevant to our business, our competitive position may be impaired, and our business, financial condition, results of operations, and prospects may be adversely affected.

If we fail to successfully enforce our intellectual property rights, our competitive position could suffer, which could harm our operating results. Competitors may challenge the validity or scope of our patents or future patents we may obtain. In addition, our licensed patents may not provide us with a meaningful competitive advantage. We may be required to spend significant resources to monitor and police our licensed intellectual property rights. We may not be able to detect infringement and our competitive position may be harmed. Proceedings to enforce our patent rights in foreign jurisdictions could result in substantial costs and divert our efforts and attention from other aspects of our business, could put our patents at risk of being invalidated or interpreted narrowly and our patent applications at risk of not issuing and could provoke third parties to assert claims against us. We may not prevail in any lawsuits that we initiate and the damages or other remedies awarded, if any, may not be commercially meaningful. In addition, competitors may design around our technology or develop competing technologies.

The technology we license, our products or our development efforts may be found to infringe upon third-party intellectual property rights.

Third parties may in the future assert claims or initiate litigation related to their patent, copyright, trademark and other intellectual property rights in technology that is important to us. The asserted claims and/or litigation could include claims against us, our licensors or our suppliers alleging infringement of intellectual property rights with respect to our products or components of those products. Regardless of the merit of the claims, they could be time consuming, result in costly litigation and diversion of technical and management personnel, or require us to develop a non-infringing technology or enter into license agreements. We have not undertaken an exhaustive search to discover any third party intellectual patent rights, which might be infringed by commercialization of the product candidates described herein. Although we are not currently aware of any such third-party intellectual patent rights, it is possible that such rights currently exist or might be obtained in the future. In the event that a third party controls such rights and we are unable to obtain a license to such rights on commercially reasonable terms, we may not be able to sell or continue to develop our products, and may be liable for damages for such infringement. We cannot assure you that licenses will be available on acceptable terms, if at all.

Furthermore, because of the potential for significant damage awards, which are not necessarily predictable, it is not unusual to find even arguably unmeritorious claims resulting in large settlements. If any infringement or other intellectual property claim made against us by any third party is successful, or if we fail to develop non-infringing technology or license the proprietary rights on commercially reasonable terms and conditions, our business, operating results and financial condition could be materially adversely affected.

If our products, methods, processes and other technologies infringe the proprietary rights of other parties, we could incur substantial costs and we may have to:

| ● | obtain licenses, which may not be available on commercially reasonable terms, if at all;

| ● | abandon an infringing drug or therapy candidate;

| ● | redesign our products or processes to avoid infringement;

| ● | stop using the subject matter claimed in the patents held by others;

| ● | pay damages; or

| ● | defend litigation or administrative proceedings which may be costly whether we win or lose, and which could result in a substantial diversion of our financial and management resources.

We rely on licenses to use various technologies that are material to our business and if the agreements were to be terminated or if other rights that may be necessary or we deem advisable for commercializing our intended products cannot be obtained, it would halt our ability to market our products and technology, as well as have an immediate material adverse effect on our business, operating results and financial condition.

We have licensing agreements with certain universities granting us the right to use certain critical intellectual property. The terms of the licensing agreements continue until the end of the life of the last patent to expire. If we breach the terms of these licensing agreements, including any failure to make minimum royalty payments required thereunder or failure to reach certain developmental milestones, using best efforts to introduce a licensed product in certain territories by certain dates, the licensor has the right to terminate the license. If we were to lose or otherwise be unable to maintain these licenses on acceptable terms, or find that it is necessary or appropriate to secure new licenses from other third parties, it would halt our ability to market our products and technology, which would have an immediate material adverse effect on our business, operating results and financial condition.

The U.S. government may have “march-in rights” to certain of our intellectual property.

Because federal grant monies were used in support of the research and development activities that resulted in certain of our issued U.S. patents of pending U.S. patent applications, the federal government retains what are referred to as “march-in rights” to patents that are granted on these applications.

In particular, the U.S Army, which administered grant monies to the primary inventor of the technology we license, technically retain the right to require us, under certain specific circumstances, to grant the U.S. government either a nonexclusive, partially exclusive or exclusive license to the patented invention in any field of use, upon terms that are reasonable for a particular situation. Circumstances that trigger march-in rights include, for example, failure to take, within a reasonable time, effective steps to achieve practical application of the invention in a field of use, failure to satisfy the health and safety needs of the public and failure to meet requirements of public use specified by federal regulations. The U.S. Army can elect to exercise these march-in rights on their own initiative or at the request of a third-party.

General Risk Factors

Changes in general economic conditions, geopolitical conditions, domestic and foreign trade policies, monetary policies and other factors beyond our control may adversely impact our business and operating results.

Our operations and performance depend on global, regional and U.S. economic and geopolitical conditions. General worldwide economic conditions have experienced significant instability in recent years including the recent global economic uncertainty and financial market conditions. Russia’s invasion and military attacks on Ukraine have triggered significant sanctions from U.S. and European leaders and financial markets around the world experienced volatility

following the invasion of Ukraine by Russia in February 2022. Resulting changes in U.S. trade policy could trigger retaliatory actions by Russia, its allies and other affected countries, including China, resulting in a “trade war.” Furthermore, if other countries, including the U.S., become further involved in the conflict, we could face significant adverse effects to our business and financial condition.

The uncertain financial markets, disruptions in supply chains, mobility restraints, and changing priorities as well as volatile asset values could impact our business in the future. The COVID-19 outbreak and government measures taken in response to the pandemic have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, have spiked, while demand for other goods and services, such as travel, have fallen. The future progression of the pandemic and its effects on our business and operations are uncertain.

​

Further, although we have not experienced any material adverse effects on our business due to increasing inflation, it has raised operating costs for many businesses and, in the future, could impact demand or pricing manufacturing of our drug candidates or services providers, foreign exchange rates or employee wages. Inflation rates, particularly in the United States and United Kingdom, have increased recently to levels not seen in years, and increased inflation may result in increases in our operating costs (including our labor costs), reduced liquidity and limits on our ability to access credit or otherwise raise capital. In addition, the Federal Reserve has raised, and may again raise, interest rates in response to concerns about inflation, which coupled with reduced government spending and volatility in financial markets may have the effect of further increasing economic uncertainty and heightening these risks.

​

Actual events involving reduced or limited liquidity, defaults, non-performance or other adverse developments that affect financial institutions or other companies in the financial services industry or the financial services industry generally, or concerns or rumors about any events of these kinds, have in the past and may in the future lead to market-wide liquidity problems. For example, on March 10, 2023, Silicon Valley Bank, was closed by the California Department of Financial Protection and Innovation, which appointed the Federal Deposit Insurance Corporation as receiver. Although we did not have any cash or cash equivalent balances on deposit with Silicon Valley Bank, uncertainty and liquidity concerns in the broader financial services industry remain and the failure of Silicon Valley Bank and its potential near- and long-term effects on the biotechnology industry and its participants such as our vendors, suppliers, and investors, may also adversely affect our operations and stock price.

We are actively monitoring the effects these disruptions and increasing inflation could have on our operations.

These conditions make it extremely difficult for us to accurately forecast and plan future business activities.

In addition, the outbreak of a pandemic could disrupt our operations due to absenteeism by infected or ill members of management or other employees, or absenteeism by members of management and other employees who elect not to come to work due to the illness affecting others in our office or laboratory facilities, or due to quarantines. Pandemics could also impact members of our Board of Directors resulting in absenteeism from meetings of the directors or committees of directors, and making it more difficult to convene the quorums of the full Board of Directors or its committees needed to conduct meetings for the management of our affairs.

​

We may not successfully effect our intended expansion, which would harm our business prospects.

Our success will depend upon the expansion of our operations and the effective management of our growth, which will place a significant strain on our management, and on our administrative, operational and financial resources. To manage this growth, we must expand our facilities; augment our operational, financial and management systems; and hire and train additional qualified personnel. If we are unable to manage our growth effectively, our business would be harmed.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future, and as a result, investors in our common stock could incur substantial losses and our ability to raise funds may be impacted.

Our stock price has fluctuated in the past, has recently been volatile and may be volatile in the future. On January 3, 2022, the reported low sale price of our common stock was $3.05 per share and the reported high sales price was $3.59 per share. For comparison purposes, on December 30, 2022, the price of our common stock closed at $0.81 per share. We may incur rapid and substantial decreases in our stock price in the foreseeable future that are unrelated to our operating performance or prospects. The stock market generally and the market for biotechnology and pharmaceutical companies in particular have experienced extreme volatility that has often been unrelated to the operating performance of particular companies. As a result of this volatility, investors may experience losses on their investment in our common stock. The market price for our common stock may be influenced by many factors, including the following:

| ● | investor reaction to our business strategy;

| ● | the success of competitive products or technologies;

| ● | our continued compliance with the listing standards of the NYSE American;

| ● | regulatory or legal developments in the United States and other countries, especially changes in laws or regulations applicable to our products;

| ● | results of our clinical trials;

| ● | actions taken by regulatory agencies with respect to our products, clinical studies, manufacturing process or sales and marketing terms;

| ● | variations in our financial results or those of companies that are perceived to be similar to us;

| ● | the success of our efforts to acquire or in-license additional products or product candidates;

| ● | developments concerning our collaborations or partners;

| ● | developments or disputes concerning patents or other proprietary rights, including patents, litigation matters and our ability to obtain patent protection for our products;

| ● | our ability to generate revenue from ANTHIM® sales;

| ● | our ability to generate revenue from our CDMO facility;

| ● | our ability or inability to raise additional capital and the terms on which we raise it;

| ● | declines in the market prices of stocks generally;

| ● | trading volume of our common stock;

| ● | sales of our common stock by us or our stockholders;

| ● | general economic, industry and market conditions; and

| ● | other events or factors, including those resulting from such events, or the prospect of such events, including war, terrorism and other international conflicts, such as the recent Russian invasion of Ukraine as well as continued and new sanctions against Russia by, among others, the European Union and the Unites States, which restrict a wide range of trade and financial dealings with Russia and Russia parties, public health issues including health epidemics or pandemics, and natural disasters such as fire, hurricanes, earthquakes, tornados or other adverse weather and climate conditions, whether occurring in the United States or elsewhere, could disrupt our operations, disrupt the operations of our suppliers or result in political or economic instability.

​

These broad market and industry factors may seriously harm the market price of our common stock, regardless of our operating performance. Since the stock price of our common stock has fluctuated in the past, has been recently volatile and may be volatile in the future, investors in our common stock could incur substantial losses. In the past, following periods of volatility in the market, securities class-action litigation has often been instituted against companies. Such litigation, if instituted against us, could result in substantial costs and diversion of management’s attention and resources, which could materially and adversely affect our business, financial condition, results of operations and growth prospects. There can be no guarantee that our stock price will remain at current prices or that future sales of our common stock will not be at prices lower than those sold to investors.

We rely on key executive officers and scientific and medical advisors, and their knowledge of our business and technical expertise would be difficult to replace.

We are highly dependent on our principal scientific, regulatory and medical advisors and our chief executive officer. Other than a $2.0 million insurance policy we hold on the life of Jeffrey Wolf, we do not have “key person” life insurance policies for any of our officers or advisors. The loss of the technical knowledge, management and industry expertise of any of our key personnel could result in delays in product development, loss of customers and sales and diversion of management resources, which could adversely affect our operating results.

If we are unable to hire additional qualified personnel, our ability to grow our business may be harmed.

We will need to hire additional qualified personnel with expertise in preclinical and clinical research, government regulation, formulation and manufacturing, sales and marketing and accounting and financing. Over the next 12 months, we expect to hire additional new employees both in North Carolina and for Scorpius in Texas. We compete for qualified individuals with numerous biopharmaceutical companies, universities, and other research institutions. Competition for such individuals is intense, and we cannot be certain that our search for such personnel will be successful especially in light of the CPRIT Grant requirements, including the requirement that Pelican maintain its headquarters in Texas and use certain vendors, consultants and employees located in Texas. Attracting and retaining qualified personnel will be critical to our success.

​

We are a smaller reporting company, and we cannot be certain if the reduced reporting requirements applicable to smaller reporting companies will make our common stock less attractive to investors.

​

We are a smaller reporting company under Rule 12b-2 of the Exchange Act. For as long as we continue to be a smaller reporting company, we may take advantage of exemptions from various reporting requirements that are applicable to other public companies that are not smaller reporting companies, including reduced disclosure obligations regarding executive compensation in our periodic reports and proxy statements. We cannot predict if investors will find our common stock less attractive because we may rely on smaller reporting company exemptions. If some investors find our common stock less attractive as a result, there may be a less active trading market for our common stock, and our stock price may be more volatile.

There can be no assurance that we will be able to comply with the applicable regulations in a timely manner, if at all.

Our failure to meet the continued listing requirements of the NYSE American LLC (the “NYSE American”) could result in a de-listing of our common stock.

Our shares of common stock are currently listed on the NYSE American. If we fail to satisfy the continued listing requirements of the NYSE American, such as the corporate governance requirements, minimum bid price requirement or the minimum stockholder’s equity requirement, NYSE American may take steps to de-list our common stock. Any de-listing would likely have a negative effect on the price of our common stock and would impair stockholders’ ability to sell or purchase their common stock when they wish to do so. In the past our common stock was listed on the Nasdaq Capital Market and we received notices from the Listing Qualifications Department of Nasdaq Stock Market LLC (“Nasdaq”) that we failed to comply with the stockholder’s equity requirements and the minimum closing bid requirements. On June 21, 2019, we received written notice from the Listing Qualifications Department of the Nasdaq Stock Market LLC notifying us that for the preceding 30 consecutive business days (May 9, 2019 through June 20, 2019), our common stock did not maintain a minimum closing bid price of $1.00 per share (“Minimum Bid Price Requirement”) as required by Nasdaq Listing Rule 5550(a)(2). On July 24, 2020, we received written notice from The Nasdaq Capital Market that from July 10, 2020 through July 23, 2020, the closing bid price of our common stock has been at $1.00 per share or greater and accordingly we had regained compliance with Nasdaq Listing Rule 5550(a)(2) and the matter was now closed. There can be no assurance given that we will be able to continue to satisfy our continued listing requirements and maintain the listing of our common stock on the NYSE American going forward.

The possible issuance of common stock subject to options, restricted stock units and warrants may dilute the interests of stockholders.

As of March 31, 2023, awards for 6,980,764 shares of common stock are outstanding under our equity compensation plans and 243,873 shares of common stock remain available for grants under the plans. In addition, as of March 31, 2023, we have warrants exercisable for 716,383 shares of our common stock to third parties in connection with our public offerings. To the extent that outstanding stock options and warrants are exercised, or additional securities are issued, dilution to the interests of our stockholders may occur. Moreover, the terms upon which we will be able to obtain additional equity capital may be adversely affected since the holders of the outstanding options can be expected to exercise them at a time when we would, in all likelihood, be able to obtain any needed capital on terms more favorable to us than those provided in such outstanding options.

​

We have additional securities available for issuance, which, if issued, could adversely affect the rights of the holders of our common stock.

Our certificate of incorporation authorizes the issuance of 250,000,000 shares of our common stock and 10,000,000 shares of preferred stock. In certain circumstances, the common stock, as well as the awards available for issuance under the incentive plans, can be issued by our Board of Directors, without stockholder approval. Any future issuances of such stock would further dilute the percentage ownership of us held by holders of preferred stock and common stock. Our Board of Directors is authorized to create and issue from time to time, only with stockholder approval, up to an aggregate of 10,000,000 shares of preferred stock of which 8,212,500 have been designated. The authority to designate preferred stock may be used to issue series of preferred stock, or rights to acquire preferred stock, that could dilute the interest of, or impair the voting power of, holders of the common stock or could also be used as a method of determining, delaying or preventing a change of control.

We have never paid dividends and have no plans to pay dividends in the future.

Holders of shares of our common stock are entitled to receive such dividends as may be declared by our Board of Directors. To date, we have paid no cash dividends on our shares of our preferred or common stock and we do not expect to pay cash dividends in the foreseeable future. We intend to retain future earnings, if any, to provide funds for operations of our business. Therefore, any return investors in our preferred or common stock may have will be in the form of appreciation, if any, in the market value of their shares of common stock.

Certain provisions of the General Corporation Law of the State of Delaware, our bylaws and stockholder rights plan may have anti-takeover effects that may make an acquisition of our company by another company more difficult.

We are subject to the provisions of Section 203 of the General Corporation Law of the State of Delaware, which prohibits a Delaware corporation from engaging in any business combination, including mergers and asset sales, with an interested stockholder (generally, a 15% or greater stockholder) for a period of three years after the date of the transaction in which the person became an interested stockholder, unless the business combination is approved in a prescribed manner. The operation of Section 203 may have anti-takeover effects, which could delay, defer or prevent a takeover attempt that a holder of our common stock might consider in its best interest. Certain provisions of our bylaws including the ability of our Board of Directors to fill vacancies on our Board of Directors and advance notice requirements for stockholder proposals and nominations may prevent or frustrate attempts by our stockholders to replace or remove our management. In addition, the Rights issued pursuant to our stockholder rights plan that we implemented, if not redeemed or suspended, could result in the dilution of the stock ownership of a potential hostile acquirer, likely preventing acquisitions that have not been approved by our Board of Directors and therefore discouraging, delaying or preventing a change in control that stockholders may consider favorable.

Our amended and restated bylaws provide that the Court of Chancery of the State of Delaware will be the exclusive forum for certain types of state actions that may be initiated by our stockholders, which could limit our stockholders’ ability to obtain a favorable judicial forum for disputes with us or our directors, officers, or employees.

​

Our amended and restated bylaws provide that, unless we consent to the selection of an alternative forum, the Court of Chancery of the State of Delaware is the exclusive forum for (i) any derivative action or proceeding brought on behalf of us, (ii) any action asserting a claim of breach of a fiduciary duty owed by any of our directors, officers, or other employees to us or our stockholders, (iii) any action arising pursuant to any provision of the DGCL or our certificate of incorporation or bylaws (as either may be amended from time to time), or (iv) any action asserting a claim governed by the internal affairs doctrine, except, in each case for claims arising under the Securities Act of 1933, as amended, the Exchange Act, or other federal securities laws for which there is exclusive federal or concurrent federal and state jurisdiction.

​

These exclusive-forum provisions may limit a stockholder’s ability to bring a claim in a judicial forum that it finds favorable for disputes with us or our directors, employees, control persons, underwriters, or agents, which may discourage lawsuits against us and our directors, employees, control persons, underwriters, or agents. Additionally, a court could determine that the exclusive forum provision is unenforceable, and our stockholders will not be deemed to have waived our compliance with the federal securities laws and the rules and regulations thereunder. If a court were to find these provisions of our amended and restated bylaws inapplicable to, or unenforceable in respect of, one or more of the specified types of actions or proceedings, we may incur additional costs associated with resolving such matters in other jurisdictions, which could adversely affect our business, financial condition, or results of operations.

​

Future sales of our common stock by our existing stockholders could cause our stock price to decline.

On March 30, 2023, we had 26,049,209 shares of our common stock outstanding, all of which are currently eligible for sale in the public market, subject, in certain circumstances to the volume, manner of sale and other limitations under Rule 144 promulgated under the Securities Act. It is conceivable that stockholders may wish to sell some or all of their shares. If our stockholders sell substantial amounts of our common stock in the public market at the same time, the market price of our common stock could decrease significantly due to an imbalance in the supply and demand of our common stock. Even if they do not actually sell the stock, the perception in the public market that our stockholders might sell significant shares of our common stock could also depress the market price of our common stock.

A decline in the price of shares of our common stock might impede our ability to raise capital through the issuance of additional shares of our common stock or other equity securities, and may cause stockholders to lose part or all of their investment in our shares of common stock.

Our shares of common stock are from time to time thinly traded, so stockholders may be unable to sell at or near ask prices or at all if they need to sell shares to raise money or otherwise desire to liquidate their shares.

Our common stock has from time to time been “thinly-traded,” meaning that the number of persons interested in purchasing our common stock at or near ask prices at any given time may be relatively small or non-existent. This situation is attributable to a number of factors, including the fact that we are a small company that is relatively unknown to stock analysts, stock brokers, institutional investors and others in the investment community that generate or influence sales volume, and that even if we came to the attention of such persons, they tend to be risk-averse and would be reluctant to follow an unproven company such as ours or purchase or recommend the purchase of our shares until such time as we became more seasoned and viable. As a consequence, there may be periods of several days or more when trading activity in our shares is minimal or non-existent, as compared to a seasoned issuer that has a large and steady volume of trading activity that will generally support continuous sales without an adverse effect on share price. We cannot give stockholders any assurance that a broader or more active public trading market for our common shares will develop or be sustained, or that current trading levels will be sustained.

Holders of our warrants will have no rights as a common stockholder until they acquire our common stock.

Until warrant holders acquire shares of our common stock upon exercise of their warrants, the warrant holders will have no rights with respect to shares of our common stock issuable upon exercise of their warrants. Upon exercise of the

52

Table of Contents

warrants, the warrant holders will be entitled to exercise the rights of a common stockholder only as to matters for which the record date occurs after the exercise date.

There is no established market for the warrants that we previously issued and our previously issued warrants may not have any value.

Our previously issued warrants to purchase shares of our common stock may not have any value. For example, we previously issued warrants in a public offering that have exercise prices of $11.55, $11.09 and $5.78 per share. In the event that our common stock price does not exceed the exercise price of our previously issued warrants during the period when the warrants are exercisable, the warrants may not have any value.

The shares of common stock offered under any at the market offering that we may engage in, and investors who buy shares at different times will likely pay different prices.

Investors who purchase shares that are sold under at-the-market-offerings at different times will likely pay different prices, and so may experience different outcomes in their investment results. We will have discretion, subject to market demand, to vary the timing, prices, and numbers of shares sold, and there is no minimum or maximum sales price. Investors may experience declines in the value of their shares as a result of share sales made at prices lower than the prices they paid.

Reports published by securities or industry analysts, including projections in those reports that exceed our actual results, could adversely affect our common stock price and trading volume.

Securities research analysts, including those affiliated with our underwriters from prior offerings, establish and publish their own periodic projections for our business. These projections may vary widely from one another and may not accurately predict the results we actually achieve. Our stock price may decline if our actual results do not match securities research analysts’ projections. Similarly, if one or more of the analysts who writes reports on us downgrades our stock or publishes inaccurate or unfavorable research about our business or if one or more of these analysts ceases coverage of our company or fails to publish reports on us regularly, our stock price or trading volume could decline. While we expect securities research analyst coverage to continue going forward, if no securities or industry analysts cover us, the trading price for our stock and the trading volume could be adversely affected.

We believe our existing properties are adequate for our current needs.

Item 3. Legal Proceedings

From time to time, we may become involved in legal proceedings or be subject to claims arising in the ordinary course of our business. We are not presently a party to any legal proceedings that, if determined adversely to us, would individually or taken together have a material adverse effect on our business, operating results, financial condition or cash flows. Regardless of the outcome, litigation can have an adverse impact on us because of defense and settlement costs, diversion of management resources and other factors.

Dividend Policy

We have never paid any cash dividends on our common stock to date, and do not anticipate paying such cash dividends in the foreseeable future. Whether we declare and pay dividends is determined by our Board of Directors at their discretion, subject to certain limitations imposed under Delaware corporate law. The timing, amount and form of dividends, if any, will depend on, among other things, our results of operations, financial condition, cash requirements and other factors deemed relevant by our Board of Directors.

Company Overview

We are a fully integrated biopharmaceutical company specializing in the end-to-end development, manufacturing, and commercialization of innovative medical countermeasures that combat unmet and emerging biothreats. Our ecosystem is driven by the discovery efforts of our subsidiary, Skunkworx, the clinical and commercial biodefense expertise of our subsidiary, Elusys, and the bioanalytical, process development and biomanufacturing capabilities of our subsidiary Scorpius. The coordination of this ecosystem potentiates the streamlined development and delivery of life-saving medical countermeasures, including our commercially available anthrax antitoxin ANTHIM® (obiltoxaximab).

​

The monoclonal antibody ANTHIM® (obiltoxaximab) received FDA approval and orphan drug exclusivity in 2016 for the treatment of inhalational anthrax in combination with antibiotics, and as a prophylaxis when alternative therapies are not available or are not appropriate. Additionally, ANTHIM® was approved in 2020 as the only licensed anthrax antitoxin treatment in the European Union (“EU”) and Canada, and in 2021 in the United Kingdom. Working closely with Biomedical Advanced Research and Development Authority (“BARDA”), the National Institute of Allergy and Infectious Disease (“NIAID”), and the Department of Defense (“DoD”), Elusys has successfully advanced ANTHIM® to the commercial stage and provides the therapeutic for inclusion in both the US Strategic National Stockpile (“SNS”) and the Public Health Agency of Canada Office of Emergency Response Services Depot.

​

Scorpius pairs cGMP biomanufacturing and quality control expertise with cutting edge capabilities in immunoassays, molecular assays, and bioanalytical methods to support cell- and gene-based therapies as well as large molecule biologics. Scorpius decreases our dependence on third-party contract research and development biomanufacturing organizations (CDMOs) for the manufacture of ANTHIM® (obiltoxaximab) and other assets and allows us to be opportunistic in offering excess capacity to third parties as a fee-for-service model. Our lead facility commenced operations in October 2022 in San Antonio, Texas. Planning and development efforts are underway on a potential commercial manufacturing facility to be built in Manhattan, Kansas in the coming years.

​

During the past year, our priorities have shifted to our biodefense and biomanufacturing capabilities resulting in a refocusing of our resources and efforts towards biodefense and biomanufacturing and away from our clinical-stage oncology assets including HS-110 and PTX-35.

​

Funding/Liquidity

We have incurred an accumulated deficit of $209.2 million through December 31, 2022. We have incurred negative cash flows from operations since we started our business. We have spent, and expect to continue to spend, substantial amounts in connection with implementing our business strategy, including our planned product development efforts, our clinical trials, and our research and discovery efforts.

We expect to incur significant expenses and continued losses from operations for the foreseeable future. We expect our expenses to increase in connection with our ongoing activities, particularly as we continue research and development and seek marketing approval for our product candidates and as we add to our product candidate pipeline including expansion of our infectious disease/biothreat programs.

We expect to incur significant additional expenses in connection with the planned development partnership of Scorpius with a private developer, the State of Kansas and local and university affiliates and the facility to be developed by a third-party developer and leased to Scorpius. We do not intend to finance the remaining costs that we will incur for the Kansas facility from working capital and instead anticipate raising financing through multiple alternatives, including, but not limited to, the sale of equity or debt of Scorpius.

The fair value of the purchase consideration for Elusys was $42.9 million pursuant to the terms of the Merger Agreement, we also paid an additional $2.0 million after having paid $3.0 million in cash consideration at closing, plus we may be required to pay an additional $1.6 million subject to adjustment upon attainment of certain milestones.

Furthermore, we anticipate increased costs associated with the manufacture of ANTHIM® and the increase in headcount due to the acquisition of Elusys. Our agreement with Lonza obligates us to pay for certain services upon placement of an

56

Table of Contents

order and only allows us to cancel manufacturing of batches for which we have placed orders under certain circumstances. Based upon the order that we placed in March 2023, we anticipate being obligated to pay over a two year period to Lonza approximately $34 million and an additional $19 million for resins and other raw materials required for production.

In addition, if we obtain marketing approval for any of our other product candidates, we expect to incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution. We will need to obtain substantial additional future funding in connection with our manufacturing facility that we are building out in San Antonio, Texas and any new programs or ventures we pursue. While we are currently funding vaccine development and preclinical studies, we do not expect to use significant corporate resources to advance our COVID-19 program. We are applying for several large grants to support clinical development of this program and are engaged in collaboration discussions, which we believe may provide attractive and non-dilutive pathways to help accelerate development of our COVID-19 program; however, to date we have not received any grant funding for such program and there can be no assurance that we will receive such grant funding or if received, the amount of such grant funding. Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts. These factors raise substantial doubt about our ability to continue as a going concern for one year after the financial statements are issued. To meet our capital needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which include sales of our common stock under at-the-market offerings, if available, debt financings, partnerships, collaborations and other funding transactions. This is based on our current estimates, and we could use our available capital resources sooner than we currently expect. We will need to generate significant revenues to achieve profitability, and we may never do so. As of December 31, 2022, we had approximately $44.3 million in cash and cash equivalents and short-term investments.

We intend to meet our financing needs through multiple alternatives, including, but not limited to, cash on hand, additional equity financings, debt financings and/or funding from partnerships or collaborations and potential revenue, if any, from our planned development and manufacturing facility.

The uncertain financial markets, disruptions in supply chains, mobility restraints, and changing priorities as well as volatile asset values could impact our business in the future. The outbreak and government measures taken in response to the pandemic have also had a significant impact, both direct and indirect, on businesses and commerce, as worker shortages have occurred; supply chains have been disrupted; facilities and production have been suspended; and demand for certain goods and services, such as medical services and supplies, have spiked, while demand for other goods and services, such as travel, have fallen. The future progression of the pandemic and its effects on our business and operations are uncertain. We may face difficulties performing services at our San Antonio facility if our workforce is impacted by the pandemic. Although we have increased manufacturing material levels in an attempt to mitigate supply chain issues, we may still face disruptions in procuring items that are essential to perform our services. In addition, we have experienced minor disruptions in equipment supply in the building of our San Antonio facility. These minor disruptions have had an immaterial effect on business, which we have been able to address with minimal impact to our business operations to date. Further, although we have not experienced any material adverse effects on our business due to increasing inflation, it has raised operating costs for many businesses and, in the future, could impact demand or pricing of our manufacturing services, the cost we incur to manufacture ANTHIM®, the costs required to build the manufacturing facility in Kansas, foreign exchange rates or employee wages. We are actively monitoring the effects these disruptions and increasing inflation could have on our operations.

CRITICAL ACCOUNTING POLICIES AND SIGNIFICANT JUDGMENTS AND ESTIMATES

We believe that several accounting policies are important to understanding our historical and future performance. We refer to these policies as "critical" because these specific areas generally require us to make judgments and estimates about matters that are uncertain at the time we make the estimate, and different estimates—which also would have been reasonable—could have been used, which would have resulted in different financial results.

Our management’s discussion and analysis of financial condition and results of operations is based on our consolidated financial statements, which have been prepared in accordance with U.S. GAAP. The preparation of our consolidated financial statements requires us to make estimates and judgments that affect the reported amounts of assets, liabilities,

57

Table of Contents

revenue and expenses and related disclosure of contingent assets and liabilities. On an ongoing basis, we evaluate our estimates based on historical experience and make various assumptions, which management believes to be reasonable under the circumstances, which form the basis for judgments about the carrying values of assets and liabilities that are not readily apparent from other sources. Actual results may differ from these estimates under different assumptions or conditions.

The notes to our audited consolidated financial statements contain a summary of our significant accounting policies. We consider the following accounting policies critical to the understanding of the results of our operations:

| ● | Revenue;

| ● | Deferred revenue;

| ● | Leases;

| ● | Intangible assets;

| ● | Goodwill impairment;

| ● | Income tax;

| ● | Contingent consideration;

| ● | Stock-based compensation;

| ● | Research and development costs, including clinical and regulatory cost; and

​

Revenue and Deferred Revenue

Our 2022 revenue primarily consisted of product sales revenue of ANTHIM® and our 2021 revenue primarily consisted of research funding from our CPRIT Grant. Product sales revenue is recognized when its performance obligation with its customers has been satisfied. The performance obligation is satisfied at a point in time when the Company’s customers obtain control of the product, which is typically upon acceptance of the product at the delivery site. Grant revenue is recognized when qualifying costs are incurred and there is reasonable assurance that the conditions of the award have been met for collection. Deferred revenue represent customer deposits for process development services billed and/or received in advance of our fulfillment of performance obligations. Deferred revenue will convert to revenue as we perform our obligations under the contract.

Leases

We determine if an arrangement is, or contains, a lease at inception. Operating and finance leases are included in right-of-use assets and lease liabilities in our consolidated balance sheets, representing our right to use an underlying asset for the lease term and the obligation to make lease payments arising from the lease. Right-of-use, or ROU, assets and lease liabilities are recognized at commencement based on the present value of lease payments over the lease term. We use our incremental borrowing rate based on the estimated rate of interest for collateralized borrowing over a similar term of the lease payments. The ROU assets also include any lease payments made and is adjusted for lease incentives. Lease terms may include options to extend or terminate the lease which are recognized when it is reasonably certain that we will exercise that option. Lease expense is recognized on a straight-line basis over the lease terms. Lease and non-lease components are accounted for as a single lease component.

Goodwill and Intangible Assets

Intangible assets represent the fair value assigned to technologies that were acquired from Elusys, which at the time of acquisition have not reached technological feasibility and have no alternative future use. Intangible assets from the acquisition of Pelican were considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. During the third quarter of 2022, Pelican’s intangible asset was fully written-off as the PTX-35 trial has been discontinued. The intangible asset acquired from the acquisition of Elusys is a definite-lived asset comprised of the ANTHIM® formulation. The asset is being amortized over 80 months, which is the approximate life of the patent.

58

Table of Contents

Intangible assets are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the assets are less than their carrying amounts. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the asset, calculated as the excess of carrying value of the intangible assets over fair value. See Note 8 regarding impairment at December 31, 2022.

We test goodwill and intangible asset impairment each year as of April 1, or more frequently should a significant impairment indicator occur. As part of the impairment test, we may elect to perform an assessment of qualitative factors. If this qualitative assessment indicates that it is more likely than not that the fair value of a reporting unit, including goodwill, is less than its carrying amount, or if we elect to bypass the qualitative assessment, we would then proceed with the impairment test. The impairment test involves comparing the fair values of the reporting units to their carrying amounts. If the carrying amount of a reporting unit exceeds its fair value, we recognize a goodwill loss in an amount equal to any excess.

Determining the fair value of a reporting unit is judgmental in nature and involves the use of significant estimates and assumptions. We forecast discounted future cash flows at the reporting unit level using risk-adjusted discount rates and estimated future revenues and operating costs, which take into consideration expectations of competitive, business, and economic environments. We also identify similar publicly traded companies and develop a correlation, referred to as a multiple, to apply to the operating results of the reporting units.

​

Determining the fair value of intangible assets is judgmental in nature and involves the use of significant estimates and assumptions. We forecast discounted future cash flows, risk-adjusted discount rates and estimated future revenues and operating costs, which take into consideration expectations of competitive, business, and economic environments. The fair value is then compared to the carrying value and if the carrying value exceeds fair value an impairment charge is recognized.

Changes in market demand, fluctuations in the markets in which we operate, the volatility and decline in the worldwide equity markets, and a decline in our market capitalization could unfavorably impact the remaining carrying value of our goodwill and intangible assets, which could have a significant effect on our current and future results of operations and financial position.

​

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with FASB ASC 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of December 31, 2022, and 2021, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations. As of December 31, 2022 and 2021, the Company had recorded no such amounts.

Contingent Consideration

Contingent consideration is recorded as a liability and is the estimate of the fair value of potential milestone and royalty payments related to business acquisitions. Contingent consideration is measured at fair value using a probability-weighted income approach utilizing significant unobservable inputs including the probability of achieving each of the potential milestone and royalty payments and an estimated discount rate associated with the risks of the expected cash flows

59

Table of Contents

attributable to the various milestones. Significant increases or decreases in any of the probabilities of success or changes in expected timelines for achievement of any of these milestones would result in a significantly higher or lower fair value of these milestones, respectively, and commensurate changes to the associated liability. The contingent consideration is revalued at each reporting period and changes in fair value are recognized in the consolidated statements of operations and comprehensive loss.

Stock-Based Compensation

Calculating stock-based compensation expense requires the input of highly subjective assumptions. The fair value of restricted stock units is estimated based on the closing price of our stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for as they occur. We apply the Black-Scholes-Merton option pricing model to determine the fair value of our stock options awards. Inherent in this model are assumptions related to expected stock-price volatility, expected option life, risk-free interest rate and dividend yield. We use an average historical stock price volatility of our own data plus an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms. We estimate the expected life of our options using the simplified method. The risk-free interest rate is based on the U.S. Treasury zero-coupon yield curve on the grant date for a maturity similar to the expected life of the options. The dividend rate is based on our historical rate, which we anticipate remaining at zero. We account for forfeitures as they occur. The assumptions used in calculating the fair value of stock options represent our best estimates, however these estimates involve inherent uncertainties and the application of management judgment. As a result, if factors change and different assumptions are used, the stock-based compensation expense could be materially different in the future.

Research and Development Costs

We expense research and development costs associated with developmental products not yet approved by the FDA as well as costs associated with bringing our developmental products into advanced phase clinical trials as incurred. These costs consist primarily of pre-manufacturing and manufacturing drug costs, clinical trial execution, investigator payments, license fees, salaries, stock-based compensation, and related personnel costs. Other costs include fees paid to consultants and outside service providers related to the development of our product candidates, and other expenses relating to the design, development, and testing and enhancement of our product candidates.

RESULTS OF OPERATIONS

Years Ended December 31, 2022 and 2021

Revenues

For the year ended December 31, 2022, we recognized $6.0 million of product sales revenue, $0.1 million of contract revenue, and $0.3 million of CPRIT grant revenue. As of December 31, 2021 we recognized $2.1 million in revenue for qualified expenditures under the CPRIT grant. The increase in product sales revenue is due to the sale of ANTHIM® to the Canadian government. The decrease in grant revenue is due to the fact that we have recognized all $15.2 million of CPRIT grant revenue. For the year ended December 31, 2022, we had a grants receivable balance of $1.5 million for CPRIT proceeds not yet received, but for which the costs had been incurred or the conditions of the award had been met. We continue our efforts to secure future non-dilutive grant funding to subsidize ongoing research and development costs.

​

Cost of sales

For the year ended December 31, 2022, we recognized $6.4 million of cost of sales. No product sales were recognized for the year ended December 31, 2021 and thus no cost of sales was recorded. The increase was due to the cost of sales related to the ANTHIM® sale to the Canadian government. Cost of sales include $5.9 million of inventory, $0.3 million of pre-acquisition backlog, and $0.2 million of shipping and fulfillment expense.

Selling, general and administrative expenses

Selling, general and administrative (“SGA”) expenses for the years ended December 31, 2022 and 2021 were $21.1 million and $16.8 million, respectively. The increase of $4.3 million was primarily due to an increase in consulting and other professional expenses to manage the business of $3.2 million, an increase in facilities expense of $1.2 million primarily due to the opening of our San Antonio facility, an increase in personnel expense of $0.8 million due to an increase in headcount, an increase in rent expense of $0.5 million, an increase in insurance expense of $0.3 million, an increase in depreciation of $0.3 million, an increase in marketing expenses of $0.2 million, an increase in software expense of $0.2 million offset by a decrease in stock-based compensation of $2.4 million.

Research and development expense

Research and development expenses increased to $23.5 million from $16.5 million for the years ended December 31, 2022 and 2021, respectively. The components of research and development expense are as follows, in millions:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ | ​ | For the year Ended
​ | ​ | December 31,
​ | ​ | 2022 |  | 2021
Programs |  | ​ |  |  | ​ |
HS-110 | ​ | $ | 0.5 | ​ | $ | 1.7
HS-130 | ​ |  | 0.7 | ​ |  | 0.9
PTX-35 | ​ |  | 2.6 | ​ |  | 2.9
ANTHIM | ​ | ​ | 1.2 | ​ | ​ | —
Other programs | ​ |  | 1.6 | ​ |  | 2.3
Unallocated research and development expenses | ​ |  | 16.9 | ​ |  | 8.7
​ | ​ | $ | 23.5 | ​ | $ | 16.5

​

| ● | HS-110 decreased by $1.2 million primarily due to a decrease in manufacturing expenses and site and investigator fees as the result of the closing of our clinical trials.

| ● | HS-130 expense decreased by $0.2 million primarily due to a decrease in site and investigator fees as the result of the closing of our clinical trials.

| ● | PTX-35 expense decreased by $0.3 million primarily due to a decrease in site and investigator fees as the result of the closing of our clinical trials.

| ● | ANTHIM® expense increased as a result of our acquisition of Elusys in April 2022.

| ● | Other programs expenses decreased by $0.7 million and include preclinical costs associated with our RapidVax program, T-cell costimulatory programs, and laboratory supplies.

| ● | Unallocated research expenses increased by $8.2 million primarily from license fees, sponsored research agreements for preclinical research, as well as increased clinical and CMC consulting expenses and Skunkworx lab and personnel costs.

Change in fair value of contingent consideration

We reassess the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. The change in the fair value of contingent consideration was ($3.4) million for the year ended December 31, 2022 compared to the change in fair value of contingent consideration of $0.4 million for the year ended December 31, 2021. The change in fair value for the year ended December 31, 2022 was primarily due to the write off of Pelican’s contingent consideration of $3.3 million due to the discontinuation of the PTX-35 and the decrease of ($0.1) million in fair value of Elusys’ contingent consideration due to the passage of time to milestone achievement as well as increased interest rates.

In-process research and development impairment

IPR&D impairment was $3.5 million and $2.4 million for the years ended December 31, 2022 and 2021, respectively. IPR&D was fully impaired during the third quarter of 2022 as the PTX-35 trial will not progress to Phase 2.

Total non-operating loss

Total non-operating loss was ($1.5) million for the years ended December 31, 2022 which primarily consisted of ($1.7) million of unrealized losses on short-term investment balances, ($0.2) million of unrealized loss on foreign currency, ($0.2) million of finance lease interest expense, ($0.4) million of loss on disposal of assets, offset by $1.0 million of interest and dividends income on short-term investment balances. Total non-operating loss was ($0.1) million for the year ended December 31, 2021 which primarily consisted of $0.9 million of interest income, and ($1.0) million of unrealized losses on short-term investment balances.

Income tax benefit

Income tax benefit was $3.3 million for the year ended December 31, 2022 compared to $0.1 million for the year ended December 31, 2021, primarily due to the recognition of Elusys’ deferred tax liability (“DTL”).

BALANCE SHEET AS OF DECEMBER 31, 2022 AND 2021

Short-term Investments. Short-term investments were $35.8 million as of December 31, 2022 compared to $88.3 million as of December 31, 2021. The decrease is primarily due the sale of investments and transferring the cash to fund the Scorpius facility build-out and other operations.

Prepaid Expenses and Other Current Assets. Prepaid expenses and other current assets were approximately $3.6 million as of December 31, 2022 and $2.9 million as of December 31, 2021. The $0.7 million increase is primarily attributable to our payments to certain vendors related to the close out process of our PTX-35 clinical trial.

Property, Plant & Equipment. Property, Plant and Equipment was approximately $20.5 million as of December 31, 2022, and $2.2 million as of December 31, 2021. The increase is attributed to a $18.3 million increase in lab equipment and leasehold improvements as a result of the Scorpius lease.

Grants Receivable. Grants receivable was $1.5 million as of December 31, 2022, and $1.3 million as of December 31, 2021. The CPRIT grant will award the remaining grant funds, on a reimbursement basis, after NightHawk has fulfilled every requirement of the grant and the grant has been approved to be finalized. The receivable relates to reimbursable costs incurred related to PTX-35.

Other Assets. Other assets were approximately $0.3 million and $12.2 million as of December 31, 2022 and 2021, respectively. The $11.9 million decrease is directly attributable to equipment purchases in 2021 for Scorpius’s new facility in San Antonio, Texas, which commenced operations in the third quarter of 2022. Other assets were then transferred into property and equipment.

Intangible Assets. As of December 31, 2022 and 2021, we had intangible assets of $8.7 million and $3.5 million. The increase was due to the ANTHIM® formulation obtained from the Elusys acquisition offset by the write off of Pelican's in-process R&D of $3.5 million due to the termination of the development of PTX-35, Pelican’s lead product candidate.

​

Goodwill. As of December 31, 2022 and December 31, 2021, we had goodwill of $3.3 million and $0.0 million, respectively. The carrying value of this asset increased by $3.3 million due to the acquisition of Elusys in April 2022.

​

Accounts Payable. Accounts payable was approximately $4.4 million and $0.9 million as of December 31, 2022 and December 31, 2021. The $3.5 million increase is due to payables related to increased operations with the opening of the Scorpius facility.

62

Table of Contents

Deferred Revenue. Deferred revenue was $1.6 million and $0.0 million as of December 31, 2022 and December 31, 2021, respectively. This deferred revenue represents proceeds received for Scorpius contracts but for which the costs have not been incurred or the conditions of the contracts not yet met.

Accrued Expenses and Other Liabilities. Accrued expenses and other liabilities were approximately $4.3 million at December 31, 2022 compared to $2.4 million at December 31, 2021. The increase is primarily due to license fee accruals, sponsored research agreements and tax accruals related to our acquisition of Elusys.

Operating and Financing Lease Liabilities. Current and long term liabilities related to operating and finance leases were $9.4 million as of December 31, 2022 and $1.9 million as of December 31, 2021. These balances are related to our Scorpius facility lease, corporate office lease and equipment leases.

Deferred Tax Liability. Deferred tax liability was approximately $0.0 million and $0.2 million for the years ended December 31, 2022 and December 31, 2021, respectively. The decrease was primarily due to the recognition of Pelican’s DTL in the third quarter of 2022 due to the abandonment of the PTX-35 trial.

Contingent Consideration. As of December 31, 2022, we had contingent consideration of $12.2 million compared to $3.3 million as of December 31, 2021. The increase is primarily related to our acquisition of Elusys. This amount represents the fair value of future milestone payments and royalities to Elusys shareholders which were discounted in accordance with ASC 820 – Fair Value Measurement. We perform an analysis on a quarterly basis and for the year ended December 31, 2022, we determined the change in the estimated fair value of the contingent consideration to be approximately ($3.5) million primarily due to the discontinuation of the PTX-35 clinical trial.

LIQUIDITY AND CAPITAL RESOURCES

Current and Future Financing Needs

Since our inception in June 2008, we have incurred significant losses and we have financed our operations with net proceeds from the private placement of our preferred stock, common stock and debt. Since our initial public offering, we have primarily financed our operations with net proceeds from the public offering of our securities and to a lesser extent, the proceeds from the exercise of warrants. During May 2018, we closed a public offering of shares of our common stock and warrants to purchase shares of our common stock in which we received net proceeds of approximately $18.8 million and after the closing of the offering, an additional $4.8 million from the exercise of 436,381 warrants issued in this offering. During November 2018, we closed a public offering of shares of our common stock and warrants to purchase shares of our common stock in which we received net proceeds of approximately $12.7 million. For the years ended December 31, 2018 and 2019, we received net proceeds of approximately $3.8 million from sales of our common stock in at-the-market offerings. On January 21, 2020, we closed an underwritten public offering of shares of our common stock and warrants to purchase shares of our common stock pursuant to which we received net proceeds of approximately $6.4 million. For the year ended December 31, 2021, we received net proceeds of $25.6 million from the sale of 2,106,027 shares of our common stock in at-the-market offerings. As of December 31, 2022, we had an accumulated deficit of approximately $209.2 million. We had net losses of $43.9 million and $35.4 million for the years ended December 31, 2022 and 2021, respectively.

We expect to incur significant commercialization expenses related to product sales, marketing, manufacturing, and distribution. We will need to obtain substantial additional future funding in connection with our manufacture of ANTHIM® and our manufacturing facility construction and set up.

​

However, the actual amount of funds we will need to operate is subject to many factors, some of which are beyond our control. These factors include the following:

​

| ● | the progress of our research activities;

| ● | our ability to attract customers for our CDMO services and ANTHIM®

| ● | the number and scope of our research programs;

| ● | the progress of our preclinical and clinical development activities;

63

Table of Contents

| ● | the progress of the development efforts of parties with whom we have entered into research and development agreements;

| ● | our expansion plans and cash needs of any new projects;

| ● | our ability to maintain current research and development licensing arrangements and to establish new research and development and licensing arrangements;

| ● | the costs involved in prosecuting and enforcing patent claims and other intellectual property rights;

| ● | the costs and timing of regulatory approvals;

| ● | the receipt of grant funding if any;

| ● | clinical laboratory development and testing;

| ● | additional manufacturing facility construction costs and equipment costs; and

| ● | manufacturing costs of ANTHIM®.

​

We have based our estimate on assumptions that may prove to be wrong. We may need to obtain additional funds sooner or in greater amounts than we currently anticipate. Potential sources of financing include strategic relationships, public or private sales of our equity or debt and other sources. We may seek to access the public or private equity markets when conditions are favorable due to our long-term capital requirements. We do not have any committed sources of financing at this time, and it is uncertain whether additional funding will be available when we need it on terms that will be acceptable to us, or at all. If we raise funds by selling additional shares of common stock, such as through the Amended and Restated Common Stock Sales Agreement with B. Riley FBR, Inc. and Cantor Fitzgerald & Co., or other securities convertible into common stock, the ownership interest of our existing stockholders will be diluted. If we are not able to obtain financing when needed, we may be unable to carry out our business plan. As a result, we may have to significantly limit our operations and our business, financial condition and results of operations would be materially harmed.

Adequate additional financing may not be available to us on acceptable terms, or at all. If we are unable to raise capital when needed or on attractive terms, we would be forced to delay, reduce or eliminate our research and development programs or any future commercialization efforts. These factors raise substantial doubt about the Company’s ability to continue as a going concern for one year after the financial statements are issued. To meet our capital needs, we are considering multiple alternatives, including, but not limited to, additional equity financings, which include sales of our common stock under at-the-market offerings, if available, debt financings, partnerships, collaborations and other funding transactions. This is based on our current estimates, and we could use our available capital resources sooner than we currently expect. We will need to generate significant revenues to achieve profitability, and we may never do so. As of December 31, 2022, we had approximately $44.3 million in cash and cash equivalents and short-term investments. The Company will need to generate significant revenues to achieve profitability, and it may never do so. Management has determined that there is substantial doubt about the Company's ability to continue as a going concern within one year after the consolidated financial statements are issued.

​

Cash Flows

Operating activities. The use of cash in both periods resulted primarily from our net losses adjusted for non-cash charges and changes in components of working capital. Net cash used in operating activities during the year ended December 31 2022 was $5.7 million compared to $38.1 million during the same period in 2021. The decrease was primarily due to an increased net loss of $8.5 million, an increase in contract receivables of $24.5 million, and an increase in inventory of $5.8 million.

Investing activities. Net cash provided by investing activities was $11.0 million during the year ended December 31, 2022 compared to $9.8 million used during the same period in 2021. The decrease is from the change in net purchases of short-term investment purchases and sales of $39.1 million, the increase in purchase of property, plant and equipment of $18.2 million from 2021 to 2022 and the $22.8 million contingent consideration payment in 2022, offset by the increasea of $2.7 million from the acquisition of Elusys.

Financing activities. Net cash used in financing activities was $4.9 million during the year ended December 31, 2022

compared to net cash provided by financing activities of $25.5 million during the year ended December 31, 2021. The

decrease of $30.4 million was primarily due to a $26.2 million net decrease in proceeds from the issuance of common

Disclosure Controls and Procedures

Under the direction and with the participation of management, including the Chief Executive Officer and Chief Financial Officer, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of December 31, 2022. We maintain disclosure controls and procedures that are designed to ensure that information required to be disclosed in its periodic reports with the Securities and Exchange Commission is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and regulations, and that such information is accumulated and communicated to management, including its principal executive officer and principal financial officer, as appropriate, to allow timely decisions regarding required disclosure. Our disclosure controls and procedures are designed to provide a reasonable level of assurance of reaching its desired disclosure control objectives.

Our Chief Executive Officer and Chief Financial Officer has concluded that, due to the material weaknesses described below, our disclosure controls and procedures were not effective as of December 31, 2022.Management’s Report on Internal Control Over Financial Reporting

65

Table of Contents

Our management is responsible for establishing and maintaining adequate internal control over financial reporting and for the assessment of the effectiveness of internal control over financial reporting. As defined by the Securities and Exchange Commission, internal control over financial reporting is a process designed by, or under the supervision of the principal executive officer and principal financial officer and implemented by our Board of Directors, management and other personnel, to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements in accordance with U.S. generally accepted accounting principles.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.

Under the supervision and with the participation of management, including the Chief Executive and Principal Financial Officer, we evaluated the effectiveness of our internal control over financial reporting as of December 31, 2022 based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, or the COSO Framework. Management’s assessment included an evaluation of the design of our internal control over financial reporting and testing of the operational effectiveness of those controls. Our Chief Executive and Financial Officer concluded that as of such date, our internal controls over financial reporting were not effective.

Material Weaknesses in Internal Control Over Financial Reporting

A material weakness (as defined in Rule 12b-2 under the Exchange Act) is a deficiency, or combination of deficiencies, in internal control over financial reporting, such that there is a reasonable possibility that a material misstatement of our annual or interim financial statements will not be prevented or detected on a timely basis.

​

Our management concluded that the following material weaknesses existed as of December 31, 2022:

​

| ● | We identified ineffective information technology general controls in the areas of user access and segregation of duties related to certain information technology systems that support our financial reporting process. As a result, certain activity level controls were also deemed to be ineffective that are dependent on information derived from these information technology systems.

​

| ● | In March 2023, we determined that we had made certain errors in the manner in which we recognized the deferred tax asset valuation allowance related to the acquisition of Elusys Therapeutics, Inc, with the result that net loss had been overstated in our quarterly filings for the periods ending June 30, 2022 through September 30, 2022. As a result, we determined that there were material errors in the financial statements that required a restatement of our Forms 10-Q for the quarterly periods ended June 30, 2022 through September 30, 2022. This was due to the inadequate design and implementation of controls to evaluate and monitor the accounting for income taxes.

| ● | We identified a material weakness related to the ineffective design of certain management review controls across a significant portion of the Company’s financial statement areas, particularly with regard to the precision of the review and evidence of review procedures performed.

​

Remediation of Material Weaknesses

In order to remediate these material weaknesses, we will change certain control activities over financial reporting to include, but are not limited to, the following: (i) evaluating and implementing enhanced process controls around user access management and segregation of duties, (ii) expanding the documentation over user access and system controls and enhancing the level of evidence maintained in management review controls and (iii) enhancing the design of existing controls and are implementing new controls over the accounting, processing, and recording of income tax.

We are committed to maintaining a strong internal control environment and implementing measures designed to help ensure that control deficiencies contributing to the material weaknesses are remediated as soon as possible.

66

Table of Contents

Notwithstanding the material weaknesses described above, management has concluded that the consolidated financial statements included in this Annual Report on Form 10-K present fairly, in all material respects, our financial position, results of operations and cash flows in conformity with GAAP.

​

Changes in Internal Control over Financial Reporting

Other than as described above, there have been no other changes in our internal control over financial reporting that have occurred during the quarter ended December 31, 2022, that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

Committees of the Board of Directors

The Board of Directors has a standing Audit Committee, Compensation Committee, and Nominating and Governance Committee. The following table shows the directors who are currently members or Chairman of each of these committees.

​

* Dr. Prendergast serves as our independent Lead Director.

Audit Committee

Our common stock is listed on the NYSE American. Under the rules of NYSE American, independent directors must comprise a majority of a listed company’s board of directors and all members of our audit, compensation and nominating and governance committees must be independent. Audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Exchange Act. Under the rules of the NYSE American, a director will only qualify as an “independent director” if, in the opinion of that company’s board of directors, that person does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

In order to be considered to be independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in his or her capacity as a member of the audit committee, the board of directors, or any other board committee: (1) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (2) be an affiliated person of the listed company or any of its subsidiaries.

Our Board undertook a review of its composition, the composition of its committees and the independence of each director. Based upon information requested from and provided by each director concerning his background, employment and

69

Table of Contents

affiliations, including family relationships, our Board has determined that Dr. Monahan, Mr. Smith and Dr. Prendergast, representing three of our four directors, do not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of these directors is “independent” as that term is defined under the rules of the NYSE American. In making this determination, our Board considered the relationships that each non-employee director has with us and all other facts and circumstances our Board deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. We intend to comply with the other independence requirements for committees within the time periods specified above.

Dr. Monahan, Mr. Smith, and Dr. Prendergast currently serve as members of the Audit Committee. The Board has determined that Dr. Monahan, Mr. Smith and Dr. Prendergast are each “independent” in accordance with the NYSE American definition of independence and each is an “audit committee financial expert”, as defined by the SEC regulations, and each has the related financial management expertise within the meaning of the NYSE American rules. The primary purpose of the Audit Committee is to act on behalf of the Board of Directors in its oversight of all material aspects of our accounting and financial reporting processes, internal controls and audit functions, including our compliance with Section 404 of the Sarbanes-Oxley Act of 2002. Pursuant to its charter, our Audit Committee reviews on an on-going basis for potential conflicts of interest, and approves if appropriate, all our “Related Party Transactions.” For purposes of the Audit Committee Charter, “Related Party Transactions” shall mean those transactions required to be disclosed pursuant to SEC Regulation S-K, Item 404. In addition, the Audit Committee reviews, acts on and reports to the Board of Directors with respect to various auditing and accounting matters, including the selection of the Company’s independent registered public accounting firm, the scope of the annual audits, fees to be paid to the independent registered public accounting firm, the performance of the Company’s independent registered public accounting firm and the accounting practices of the Company and the Company’s internal controls and legal compliance functions. The Committee also reviews, prior to publication, our quarterly earnings releases and our reports to the Securities and Exchange Commission on Forms 10-K and 10-Q. The Audit Committee operates pursuant to a written charter adopted by the Board of Directors, which is available on the Company’s website at www.nighthawkbio.com. The charter describes the nature and scope of responsibilities of the Audit Committee.

Compensation Committee

Our Compensation Committee is comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast, each of whom is deemed to be independent in accordance with the NYSE American definition of independence. Compensation Committee members must also satisfy the independence criteria set forth in Rule 10C-1 under the Exchange Act. This Committee determines, approves, and reports to the Board of Directors on all elements of compensation of our executive officers. The Compensation Committee also has the power to prescribe, amend, and rescind rules relating to our stock incentive plans, to recommend the grant of options and other awards under the stock incentive plans, and to interpret the stock incentive plans.

The Compensation Committee operates under a formal charter that governs its duties and standards of performance. A copy of the charter is available on our website at www.nighthawkbio.com.

Our Compensation Committee annually reviews the compensation program for our Chief Executive Officer and other members of senior management and then makes recommendations to the full board for determination. In each case, the Committee takes into account the results achieved by the executive, his or her future potential, and his or her scope of responsibilities and experience. During our fiscal year ended December 31, 2022, the Committee evaluated the performance of our executives and considered the compensation levels and equity programs at comparable companies and related industries and the analysis of its outside consultant before it made its compensation recommendations to the full board, including recommendations regarding salary increases, awards of cash bonuses and awards of stock options.

The Committee administers our equity incentive plans, including review and recommendation of long-term incentive compensation for each executive, director and employee, including grants of stock options. The Committee believes that this long-term incentive compensation aligns the interests of our executives with those of our stockholders and furthers executive retention.

70

Table of Contents

The Committee also reviews and recommends to the Board of Directors appropriate director compensation programs for service as directors, committee chairs and committee members.

Nominating and Governance Committee

The Nominating and Governance Committee is comprised of Dr. Monahan, Mr. Smith, and Dr. Prendergast.

The functions performed by the Nominating and Governance Committee include:

| ● | recommending to the Board of Directors individuals for appointment to vacancies on any committee of the Board of Directors;

| ● | recommending to the Board of Directors regarding any changes to the size of the Board of Directors or any committee;

| ● | reporting to the Board of Directors on a regular basis; and

| ● | performing any other duties or responsibilities expressly delegated to the committee by the Board of Directors relating to board or committee members.

Candidates for director should have certain minimum qualifications, including the ability to understand basic financial statements, being over 21 years of age, having relevant business experience (taking into account the business experience of the other directors), and having high moral character. The Committee retains the right to modify these minimum qualifications from time to time.

In evaluating an incumbent director whose term of office is set to expire, the Nominating and Governance Committee reviews such director’s overall service to the Company during such director’s term, including the number of meetings attended, level of participation, quality of performance, and any transactions with the Company engaged in by such director during his term.

When selecting a new director nominee, the Committee first determines whether the nominee must be independent for NYSE American purposes or whether the candidate must qualify as an “audit committee financial expert.” The Committee then uses its network of contacts to compile a list of potential candidates, but may also engage, if it deems appropriate, a professional search firm to assist in the identification of qualified director candidates. The Committee also will consider nominees recommended by our stockholders. The Nominating and Governance Committee does not distinguish between nominees recommended by our stockholders and those recommended by other parties. The Committee evaluates the suitability of potential nominees, taking into account the current board composition, including expertise, diversity and the balance of inside and independent directors. The Nominating and Governance Committee endeavors to establish a diversity of background and experience in a number of areas of core competency, including business judgment, management, accounting, finance, knowledge of our industry, strategic vision, research and development and other areas relevant to our business.

In considering any person recommended by one of our stockholders, the Committee will look for the same qualifications that it looks for in any other person that it is considering for a position on the Board of Directors. The Nominating and Governance Committee operates under a formal charter that governs its duties and standards of performance. A copy of the charter is available on our website at www.nighthawkbio.com.

Ad Hoc Committees

From time to time we establish ad hoc committees to address particular matters.

Board Leadership Structure

Mr. Wolf, the Company’s Chief Executive Officer, also serves as Chairman of the Board of Directors. We have a separate, independent Lead Director. Although we do not have a formal policy addressing the topic, we believe that when the

71

Table of Contents

Chairman of the Board is an employee of the Company or otherwise not independent, it is important to have a separate Lead Director, who is an independent director.

Dr. Prendergast serves as the Lead Director. In that role, he presides over the Board’s executive sessions, during which our independent directors meet without management, and he serves as the principal liaison between management and the independent directors of the Board. The Lead Director also:

| ● | confers with the Chairman of the Board regarding Board meeting agenda;

| ● | chairs meetings of the independent directors including, where appropriate, setting the agenda and briefing the Chairman of the Board on issues discussed during the meeting;

| ● | oversees the annual performance evaluation of the CEO;

| ● | consults with the Nominating and Governance Committee and the Chairman of the Board regarding assignment of Board members to various committees; and

| ● | performs such other functions as the Board may require.

We believe the combination of Mr. Wolf as our Chairman of the Board and an independent director as our Lead Director is an effective structure for our company. The division of duties and the additional avenues of communication between the Board and our management associated with this structure provide the basis for the proper functioning of our Board and its oversight of management.

Risk Oversight

The Board has an active role, as a whole and also at the committee level, in overseeing management of our company’s risks. The Board regularly reviews information regarding our company’s strategy, finances and operations, as well as the risks associated with each. The Audit Committee is responsible for oversight of Company risks relating to accounting matters, financial reporting, internal controls and legal and regulatory compliance. The Audit Committee undertakes, at least annually, a review to evaluate these risks. The members then meet separately with management responsible for such area, including our Chief Financial Officer, and report to the Audit Committee on any matters identified during such discussions with management. In addition, the Compensation Committee considers risks related to the attraction and retention of talent as well as risks relating to the design of compensation programs and arrangements. In addition, the Nominating and Governance Committee manages risks associated with the independence of the Board. While each committee is responsible for evaluating certain risks and overseeing the management of such risks, the entire Board is regularly informed through committee reports about such risks. The full Board considers strategic risks and opportunities and regularly receives detailed reports from the committees regarding risk oversight in their respective areas of responsibility.

Code of Business Conduct and Ethics

We have long maintained a Code of Business Conduct and Ethics that is applicable to all of our directors, officers and employees. We undertake to provide a printed copy of these codes free of charge to any person who requests. Any such request should be sent to our principal executive offices attention: Corporate Secretary. The code is posted on our website at www.nighthawkbio.com.

​

Item 11. Executive Compensation

We are a “smaller reporting company” and the following compensation disclosure is intended to comply with the requirements applicable to smaller reporting companies. Although the rules allow us to provide less detail about our executive compensation program, the Compensation Committee is committed to providing the information necessary to help stockholders understand its executive compensation-related decisions. Accordingly, this section includes supplemental narratives that describe the 2022 executive compensation program for our named executive officers.

Set forth below is the compensation paid or accrued to our Named Executive Officers during the years ended December 31, 2022 and 2021:

Narrative Disclosure To Summary Compensation Table

Overview of Our Compensation Program

A. Philosophy and Objectives

Our primary objective with respect to executive compensation is to design compensation programs that will align executives’ compensation with our overall business strategies for the creation of stockholder value and attract, motivate and retain highly qualified executives.

Our executive compensation program is based on the following philosophies and objectives:

| ● | Compensation Should Align with Stockholders’ Interests — The Compensation Committee and our Board believes that executives’ interests should be aligned with those of the stockholders. Executives are granted restricted stock and stock options so that the majority of their total compensation is tied directly to the value realized by our stockholders. Executive bonuses are tied directly to company strategy and operational execution which contributed to our success as a whole.

| ● | Compensation is Competitive — The Compensation Committee and Board seek to provide a total compensation package that attracts, motivates and retains the executive talent that we need in order to maximize the return to stockholders and execute our operational and scientific strategy. To accomplish this objective, executive compensation is reviewed annually to ensure that compensation levels are competitive and reasonable in relation to comparable companies with which we compete for talent.

| ● | Compensation Motivates and Rewards the Achievement of Goals — Our executive compensation program is designed to appropriately reward both individual and collective performance that meets and exceeds our annual and long-term strategic and operational goals. To accomplish this objective, a substantial percentage

Table of Contents

|  | of total compensation is variable and/or “at risk”, both through annual incentive compensation and the granting of long-term incentive awards.

We seek to achieve these objectives through three key compensation elements:

| ● | a base salary;

| ● | a performance-based annual cash incentive (i.e., annual cash incentive compensation); and

| ● | long term equity awards.

In order to enhance the Compensation Committee’s ability to carry out its responsibilities effectively, as well as maintain strong links between executive pay and performance, the Compensation Committee reviews compensation information for each Named Executive Officer, which includes the following information:

| ● | the annual compensation and benefit values that are being offered to each executive;

| ● | the value of all outstanding equity awards; and

| ● | discussions with our Chairman, Chief Executive Officer and other senior management in connection with compensation matters, as well as compensation consultants and other advisors from time to time.

B. Compensation Administration

Roles and Responsibilities of Compensation Committee

The primary purpose of the Compensation Committee is to conduct reviews of our general executive compensation policies and strategies and oversee and evaluate our overall compensation structure and programs. The Compensation Committee confirmed that total compensation paid to our Named Executive Officers during the year ended December 31, 2022, was reasonable and competitive. The following were our Named Executive Officers for the year ended December 31, 2022: Jeffrey Wolf, our Chief Executive Officer and William L. Ostrander, our Chief Financial Officer (collectively, our “Named Executive Officers”). Responsibilities of the Compensation Committee include, but are not limited to:

| ● | Establishing on an annual basis performance goals and objectives for purposes of determining the compensation of our Chief Executive Officer and other senior executive officers, evaluating the performance of such officers in light of those goals and objectives, and setting the compensation level for those officers based on this evaluation.

| ● | Recommending to the Board the compensation for independent Board members (including retainer, committee and committee chair’s fees, stock options and components of compensation as appropriate).

| ● | Reviewing the competitive position of, and making recommendations to the Board with respect to, the cash-based and equity-based compensation plans and other programs relating to compensation and benefits.

| ● | Reviewing our financial performance and operations as well as our major benefit plans.

| ● | Overseeing the administration of our equity and other executive compensation plans, including recommending to the Board of Directors the granting of equity awards under those plans, and the approval or disapproval of the participation of individual employees in those plans.

| ● | Reviewing and approving for our Chief Executive Officer and other senior executive officers: (a) employment agreements; (b) severance agreements; (c) change in control agreements/provisions; and (d) any other material perquisites or other in-kind benefits.

Use of Compensation Consultant

The Compensation Committee retained Meridian Compensation Partners, LLC (“Meridian”), a nationally-recognized global human resources consulting firm, as its independent compensation advisor in 2021 and 2022. Meridian principally provides analysis, advice and recommendations regarding named executive officer and non-employee director compensation as well as guidance and considerations on our long-term incentive program for all eligible employees including salary, bonus, benefits and equity awards for our executive officers and retainers, meeting fees and equity awards for our directors. Meridian reports to the Chairman of the Compensation Committee and has direct access to the other members of the Compensation Committee. Meridian does not provide any other services to the Company other than in its role as the Compensation Committee’s independent advisor. The Compensation Committee has evaluated Meridian’s reports and, as they considered appropriate to achieve the best interests of the Company and its stockholders, implemented the recommendations.

The Compensation Committee considered whether Meridian had any conflicts of interest in advising the Committee. In doing so, the Compensation Committee considered whether Meridian had been providing services of any other nature to us; the amount of fees received from us by Meridian; the policies and procedures adopted by Meridian that have been designed to prevent conflicts of interest; whether any business or personal relationships existed between the consultants employed by Meridian who worked on our matters and any member of the Compensation Committee; whether any business or personal relationship existed between such consultants and any of our executive officers; and whether Meridian or such consultants hold any of our common stock. Upon evaluating such considerations, the Committee found no conflicts of interest in Meridian advising the Compensation Committee.

Role of the Chief Executive Officer

Our Chief Executive Officer, Mr. Wolf, makes recommendations to the Compensation Committee regarding the compensation of our other named executive officers. Mr. Wolf does not participate in any discussions or processes concerning his own compensation and participates in a non-voting capacity in discussions or processes concerning the compensation of our Chief Financial Officer and other members of management.

Compensation Committee Consideration of Shareholder Advisory Votes

At our annual meeting of stockholders held on September 15, 2022, we submitted our executive compensation program that covers our Named Executive Officers to our stockholders for a nonbinding advisory vote. Our executive compensation program did not receive the support of holders of a majority of the shares that voted on this proposal at the annual meeting of stockholders (including abstentions but excluding broker non-votes). In response to the vote, with respect to 2022 compensation, we did not grant Mr. Wolf shares of restricted stock which in prior years resulted in a tax being required to be paid upon grant and resulted in a special bonus being granted to Mr. Wolf to cover taxes and instead we granted him options, which are not taxed upon grant and therefore we did not issue a special bonus to cover taxes. In addition, at our annual meeting of stockholders held on July 23, 2019, our stockholders voted on an advisory basis with respect to the frequency of future advisory votes on our executive compensation program. Holders of a majority of the shares that voted on this proposal at the meeting (including abstentions but excluding broker non-votes) expressed their preference for an advisory vote every three years. Accordingly, we intend to hold an annual advisory vote on executive compensation at our annual meeting of stockholders in 2023.

C. Competitive Considerations

In making compensation decisions with respect to each element of compensation for our Named Executive Officers, the Compensation Committee believes that it is important to be informed as to the competitive market practices at similarly situated public companies. In setting 2022 target total direct compensation levels for our Named Executive Officers, the Compensation Committee relied in part on reports prepared by Meridian effective December 7, 2022. Meridian conducted a comprehensive assessment of our Named Executive Officer’s pay program relative to a peer group of 17 similarly-

75

Table of Contents

situated public companies that were pre-revenue cancer therapeutics companies with market capitalizations between $150 million and $1.6 billion. The elements of the Named Executive Officer’s pay programs assessed against peer group practices for 2022 included: (1) base salary, (2) target annual incentives (bonuses), (3) target total cash compensation, (4) long-term incentives and (5) target total direct compensation. In addition, Meridian also provided an analysis of our pay mix relative to peer group practices. Meridian’s assessment included our Chief Executive Officer and Chief Financial Officer. The Compensation Committee considered the competitive market pay data of our peer group that was included in Meridian’s analysis and relevant survey data when setting each Named Executive Officer’s compensation.

The Compensation Committee’s desired competitive positioning and its pay program decision-making (in terms of both compensation levels and overall mix of pay which is focused on variable or “at risk” compensation) is reflective of our pay for performance philosophy and provides alignment of executive interests with those of our stockholders.

We believe that, given the industry in which we operate and our compensation philosophy and objectives, our approach to executive compensation is sufficient to retain our current executive officers and to hire new executive officers when and as required.

D. Components of Compensation

The allocation between cash and non-cash named executive officer compensation is influenced by subjective and objective factors considered by the Compensation Committee and is intended to reflect the Compensation Committee’s determination of the appropriate compensation mix among base pay, annual cash incentives and long-term equity incentives for each named executive officers.

1. Base Salaries

We provide our Named Executive Officers a competitive level base salary commensurate with their position, responsibilities and experience. In setting the base salary, the Compensation Committee considers a number of factors including, peer group market data, our company performance and each Named Executive Officer’s role and responsibilities, experience and individual performance. We design base pay to be competitive in attracting and retaining top talent.

Initial base salaries for the Named Executive Officers were set by their initial respective employment contracts and are reviewed annually by the Compensation Committee. The Compensation Committee determined that our Chief Executive’s Officer’s and Chief Financial Officer’s 2022 base salary levels were below market practice of our peer group; therefore the base salaries were increased in January 2022. The 2021, 2022, and 2023 base salaries for our current Named Executive Officers are as follows:

​

​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​ | ​
Named Executive Officer |  | Base Salary 2021 | ​ | Base Salary 2022 |  | Base Salary 2023
Jeffrey Wolf, Chief Executive Officer | ​ | $ | 540,000 | ​ | $ | 561,600 | ​ | $ | 575,000
William L. Ostrander, Chief Financial Officer | ​ | $ | 275,000 | ​ | $ | 350,000 | ​ | $ | 375,000

​

2. Bonuses

For 2022, the Compensation Committee recommended to the full Board of Directors the following bonus payouts to our Named Executive Officers:

| ● | Jeffrey Wolf bonus. The Board approved the Compensation Committee’s recommendation that Mr. Wolf receive a $281,000 cash bonus (50% of gross salary increased to 55% in December 2022).

| ● | William Ostrander bonus. The Board approved the Compensation Committee’s recommendation that Mr. Ostrander receive a $122,500 cash bonus (35% of gross base salary increased to 40% in December 2022).

76

Table of Contents

The employment agreement with Jeffrey Wolf that was in effect during 2021 and 2022 provided that he was eligible for a cash performance bonus of up to fifty percent (50%) of his base salary which was increased to fifty five (55%) in December 2022 as well an equity bonus in the sole discretion of the Board of Directors, with the actual amount of any such bonus increased or decreased in the sole discretion of the Board of Directors. William L. Ostrander’s employment agreement that was in effect for 2022 provided for an annual bonus of up to thirty-five percent (35%) of his base salary which was increased to forty (40%) in December 2022 as well as an equity bonus in the sole discretion of the Board of Directors, with the actual amount of any such bonus increased or decreased in the sole discretion of the Board of Directors. The Compensation Committee believes that the granting of a bonus is appropriate to motivate the Named Executive Officers. The Compensation Committee focuses on individual performance, which enables the Compensation Committee to differentiate among executives and emphasize the link between personal performance and compensation. Although the Compensation Committee does not use any fixed formula in determining bonuses, it does link them to financial objectives of importance to it.

3. Long-Term Incentives

A substantial portion of the Named Executive Officer’s total compensation is in the form of equity-based compensation to encourage retention and better align the interests of the Named Executive Officers with the stockholders. The Compensation Committee determined to grant a combination of stock options and restricted stock awards to the current Named Executive Officers and other key employees as the primary long-term incentive vehicles.

In 2021 and 2022 the Compensation Committee determined the size of equity awards granted to the Named Executive Officers based on the following factors: accounting impact, peer group market data, our company performance and each Named Executive Officer’s position, role and responsibilities, experience, tenure, individual performance and pro forma percent ownership. In addition, the Compensation Committee considered that there was a lack of realizable value from their prior awards since substantially all of the prior awards were of significant low value and/or underwater or held low value. The Compensation Committee also sought to better align the Chief Executive Officer’s equity ownership interest in our company with that of other chief executive officers of our peer group companies. The Compensation Committee determined in December 2022 to grant a combination of options to the Chief Executive Officer and the Chief Financial Officer.

On December 7, 2022, Mr. Wolf and Mr. Ostrander were granted a ten-year option to purchase 2,843,137 and 490,196 shares of our common stock respectively of which one third vests on January 2023 and the balance vests pro-rata over 36 months.

In January 2021, Mr. Wolf was granted 288,100 restricted stock awards as part of his long-term incentive compensation for the year ended December 31, 2021. On December 13, 2021, Mr. Wolf was also awarded 246,305 shares of restricted common stock, half of which vested immediately and the remaining half vested on January 1, 2022. The 246,305 shares of restricted stock were awarded pursuant to the terms of an amended and restated restricted stock agreement. The restricted stock awards vested 50% immediately and 50% on the one-year anniversary of the grant date. The restricted stock agreements with respect to the foregoing grants, among other things, prohibit transfers of the restricted stock prior to the two-year anniversary of the grant date other than by will, laws of descent and distribution and in the event of death. In addition, sales or transfers made after the two year anniversary of the grant date are subject to the right of us to buy back the stock at any time that the holder desires to sell the restricted stock at a price equal to the lower of the closing price per share and 17 times the closing price per share on the date of grant with respect to the 2020 and 2021 grants and 10 times the closing price per share on the date of grant with respect to the 2021 grants. In January 2021, Mr. Wolf was also granted an option to purchase up to 147,980 shares of common stock that vest on the two-year anniversary of the grant date. On December 13, 2021 and December 31, 2021, Mr. Wolf was awarded an option to purchase 161,774 and 231,987 shares of our common stock, respectively.

On December 13, 2021, Mr. Ostrander was awarded a ten-year option to purchase 68,807 shares of our common stock. Mr. Ostrander was issued 51,487 option awards on January 4, 2021.

On August 2, 2021, the Board of Directors adopted the Heat Biologics, Inc. 2021 Subsidiaries Stock Incentive Plan (the “SSIP”). The SSIP is designed to compensate employees of our subsidiaries based on their responsibilities and for their

77

Table of Contents

contributions to the successful achievement of certain corporate goals and objectives of such subsidiaries and to share the success and risks of such subsidiaries based upon achievement of business goals. In addition, in August we issued to Mr. Wolf options under the SSIP to purchase 10,526, 10,638, 10,526 and 10,526 shares of common stock of Skunkworx, Scorpius, Abacus, and Blackhawk, respectively and we issued Mr. Ostrander 2,127 shares of common stock of Scorpius, all subject to forfeiture if the Subsidiary Plan was not approved by our stockholders at our annual meeting so stockholders. At our Annual Meeting of Stockholders held on September 15, 2021, the SSIP was approved by our stockholders. Skunkworx, Scorpius, Abacus, and Blackhawk currently have 200,100, 200,100, 200,000 and 200,000 shares outstanding, respectively.

The Compensation Committee does not seek to time equity grants to take advantage of information, either positive or negative, about our company that has not been publicly disclosed. Option grants are effective on the date the award determination is made by the Compensation Committee, and the exercise price of options is the closing market price of our common stock on the business day of the grant or, if the grant is made on a weekend or holiday, on the prior business day.

Employment Agreements

On December 18, 2009, we entered into an employment agreement with Jeffrey Wolf to act as our Chief Executive Officer, which agreement was amended on November 22, 2011, and further amended on each of January 20, 2014, January 11, 2016, January 1, 2017 and January 2, 2020 (the “Prior Agreement”). Pursuant to the employment agreement in effect during 2020, Mr. Wolf received an annual base salary of $540,000 per year. He was also eligible to receive, at the sole discretion of the board, an additional cash performance-based bonus equal to up to 50% of his then outstanding base salary at the end of each year and a discretionary equity award, with the actual amount of his bonus to be increased or decreased in the sole discretion of the Board of Directors. In addition, he was also eligible to receive certain options to purchase 2% of our fully diluted equity at an exercise price equal to the then current market price if our stock is traded on a nationally recognized exchange or Nasdaq and our market capitalization is at least $500 million for at least 15 business days, which milestone was achieved in July 2020.

On January 4, 2021, we entered into a new employment agreement with Jeffrey Wolf (the “Wolf Agreement”) to continue to serve as our Chief Executive Office and President, which agreement replaces the Prior Agreement agreement. Pursuant to the terms of the Wolf Agreement, Mr. Wolf will receive an annual base salary of $540,000 per year which was amended in December 2022 to $575,000. He also may receive, at the sole discretion of the board, an additional cash performance-based bonus equal to up to fifty percent (50%) of his then outstanding base salary at the end of each year (which was amended to fifty five (55%) in December 2022) and a discretionary equity award, with the actual amount of his bonus to be increased in the sole discretion of the Board of Directors. In addition, he is to receive (i) an incentive cash bonus in an amount equal to 2% of the Transaction Consideration (as defined in the agreement) paid in connection with the consummation of a Change in Control (as defined in the agreement), provided that such Change in Control results in the stockholders of the Company receiving (or being entitled to receive, whether upon the consummation of the Change in Control or at a future date) transaction consideration worth at least 125% of the average closing trading price of the Company’s common stock during the 20 trading-day period immediately preceding the consummation of the Change in Control and (ii) an equity bonus in the form of additional stock options or restricted stock units or shares of restricted stock equal to 2% of the total fully-diluted equity of the Company if the market capitalization of the Company is equal to or exceeds a valuation of $500 million or more for fifteen (15) business days or longer. In addition, subject to certain condition, Mr. Wolf may also be entitled to receive equity in newly formed subsidiaries of the Company. If the Wolf Agreement is terminated for death or disability (as defined in the Wolf Agreement), he (or his estate in the event of death) will receive any unpaid base salary through the date of death or disability, any unpaid target bonus earned through date of termination and he shall be entitled to exercise any vested awards for the shorter of 24 months after termination and the remaining term of the award. If Mr. Wolf’s employment is terminated by us other than for Cause (as defined in the

79

Table of Contents

agreement) or by him for Good Reason (as defined in the Wolf Agreement), he will receive a payment of an amount equal to one (1) times his annual base salary plus his annual target bonus amount for the year of termination assuming payment in full of the annual target bonus, accelerated vesting of all unvested equity awards, extension of the time period in which to exercise awards equal to the lesser of 24 months after termination or the remaining term of the award and payment of COBRA premiums for the earlier or twelve months, the date he becomes eligible for other group benefits or his rights to COBRA expire. In addition, in the event the Company terminates Mr. Wolf’s employment upon or at any time in connection with a Change of Control Transaction (as defined in the Wolf Agreement), Mr. Wolf is entitled to a lump sum cash payment equal to 24 months of his current base pay, a cash payment equal to a pro-rated amount of his target annual target bonus for the year preceding termination, payment in full for COBRA for 12 months following termination and immediate vesting of the unvested portion of any outstanding equity awards and a period to exercise the awards equal to the lesser of 12 months after termination or the remaining term of the award. If within one year after the occurrence of a Change in Control, the Executive terminates his employment for Good Reason or the Company terminates his employment for any reason other than death, disability of cause Mr. Wolf is entitled to a lump sum cash payment equal to 24 months of his current base pay, a cash payment equal to his full target annual target bonus, payment in full for COBRA for 12 months following termination and immediate vesting of the unvested portion of any outstanding equity awards and a period to exercise the awards equal to the lesser of 24 months after termination or the remaining term of the award. Under the Wolf Agreement, Mr. Wolf has also agreed to non-competition provisions.

Effective September 24, 2019 we entered into an offer letter with Mr. Ostrander to serve as our Vice President of Finance and Secretary. Effective January 4, 2021, Mr. Ostrander, was promoted to Chief Financial Officer. In connection with Mr. Ostrander’s new role as our Chief Financial Officer, effective January 4, 2021, we entered into an amendment (the “Ostrander Amendment”) to the offer letter, dated September 23, 2019, which had been amended on January 1, 2020. Pursuant to the Ostrander Amendment, Mr. Ostrander’s base salary was increased from $226,600 to $275,000 and his bonus target was increased to 30% of his base salary. Mr. Ostrander was also eligible for other benefits consistent with those received by our other executives.

On December 15, 2021, we entered into a four-year employment agreement, effective as of January 1, 2022, with William Ostrander (the “Ostrander Employment Agreement”), to continue to serve as our Chief Financial Officer and Corporate Secretary. The Ostrander Employment Agreement replaced the Offer Letter entered into by us with Mr. Ostrander, dated September 23, 2019, as amended on January 1, 2020 and January 4, 2021. Pursuant to the Ostrander Employment Agreement, Mr. Ostrander is entitled to an annual base salary of $350,000 which was amended in December 2022 to $375,000 and will be eligible for discretionary performance bonus payments of thirty-five percent (35%) (which was amended to forty (40%) in December 2022) of his annual base salary. If Mr. Ostrander’s employment is terminated for any reason, he or his estate as the case may be, will be entitled to receive the accrued base salary, vacation pay, expense reimbursement and any other entitlements accrued by him to the extent not previously paid (the “Accrued Obligations”); provided, however, that if his employment is terminated by us without Just Cause (as defined in the Ostrander Employment Agreement) then in addition to paying the Accrued Obligations, (i) we shall continue to pay his then current base salary for a period of six (6) months; and (ii) the vesting on all unvested options shall be accelerated so that all options shall become fully vested. If his employment is terminated within one year of a Change of Control (as defined in the 2018 Stock Incentive Plan), he will be paid his then current base salary for a period of six (6) months.

Our Compensation Committee conducted an evaluation of the compensation of the members of our Board of Directors for 2022 with assistance from Meridian. Based on Meridian’s review, the Compensation Committee determined that the director pay program was consistent with competitive market practices (relative to NightHawk’s publicly traded peer group at that time), aligned with our overall philosophy and approach to director pay and reflective of desired competitive positioning. For 2022 after consultation with Meridian, it was determined that directors who are not employees will receive an annual cash fee of $55,000 as well as a cash fee of $8,000 for service on the Audit Committee and $5,000 for service on each of the Compensation Committee and the Nominating and Governance Committee. In addition, the Chairman of each of the Audit, Compensation and Nominating and Governance Committees will each receive an additional cash fee of $12,500, $8,500 and $7,000, respectively. The lead independent director receives a monthly fee of $14,000 for his services as lead independent director.

Equity Compensation Plan Information

See Part II, Item 5, “Equity Compensation Plan Information” for certain information regarding our equity compensation plans.

Item 13. Certain Relationships and Related Transactions, and Director Independence

Pursuant to our charter, our Audit Committee shall review on an on-going basis for potential conflicts of interest, and approve if appropriate, all our “Related Party Transactions” as required by Section 120 of the NYSE American Company Guide. For purposes of the Audit Committee Charter, “Related Party Transactions” shall mean those transactions required to be disclosed pursuant to SEC Regulation S-K, Item 404.

The following is a summary of transactions since January 1, 2021 to which we have been a party in which the amount involved exceeded $120,000 and in which any of our executive officers, directors or beneficial holders of more than five percent of our capital stock had or will have a direct or indirect material interest, other than compensation arrangements which are described under the sections of this Annual Report entitled Part III, Item 10. “Directors, Executive Officers and Corporate Governance—Director Compensation” and Part III, Item 11. “Executive Compensation:”

Compensation paid to our executive officers during 2021 and 2022 and equity awards granted to our executive officers and directors during 2021, 2022, 2023 and payments due to interests in Pelican, are disclosed under the sections of this Annual Report on Form 10-K entitled Part III, Item 10. “Directors, Executive Officers and Corporate Governance—2022 Director Compensation” and Part III, Item 11. “Executive Compensation” and Note 4 to the Company's audited consolidated financial statements for the years ended December 31, 2022 and 2021 “Acquisition of Pelican Therapeutics.”

​

On December 20, 2021, we entered into the Merger Agreement with Merger Sub, Elusys and Fortis Advisors LLC pursuant to which, subject to certain conditions, we intend to acquire Elusys through the Merger. Elusys was formed in 1998 by Jeff Wolf, our President, Chief Executive Officer and Chairman of the Board of Directors, who is a director of Elusys and directly and through affiliated entities owns approximately 1.2% of the outstanding stock of Elusys, in the form of common stock, which is subordinate in terms of distributions to the Elusys preferred stock. However, pursuant to the terms governing the Elusys preferred stock, the preferred stockholders of Elusys will receive all of the initial $5 million of Merger Consideration and all of the net payments from the $31 million of revenues related to fulfillment of the existing SNS contract. While the amount of earn out payments, if any, to be made over the 12 year period following closing is very uncertain, it also presently seems likely that most if not all of such payments will also be paid to the preferred stockholders of Elusys under the terms of such preferred stock. See” Business Recent Developments” for a more complete description of the Merger Agreement.

Indemnification agreements

Our third amended and restated certificate of incorporation contains provisions limiting the liability of directors and our amended and restated bylaws provide that we will indemnify each of our directors to the fullest extent permitted under Delaware law. In addition, we have entered and expect to continue to enter into agreements to indemnify our directors.

Independence of the Board of Directors

The Board of Directors undertook a review of the independence of the members of the Board of Directors and considered whether any director has a material relationship with our company that could compromise his or her ability to exercise independent judgment in carrying out his or her responsibilities. Based upon information requested from and provided by each director concerning their background, employment and affiliations, including family relationships, the Board of

Table of Contents

Directors has determined that all of our current directors, except Mr. Wolf, due to his position as President and Chief Executive Officer of our company, are “independent” as that term is defined under the rules of NYSE American. As a result, Dr. Monahan, Dr. Prendergast and Mr. Smith are deemed to be “independent” as that term is defined under the rules of NYSE American. See the section of this Annual Report entitled “Item 10. Directors, Executive Officers and Corporate Governance.”

Item 14. Principal Accountant Fees and Services

Independent Registered Public Accounting Firm Fees and Services

The following table sets forth the aggregate fees including expenses billed to us for the years ended December 31, 2022 and 2021 by BDO USA, LLP.

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | December 31, |  | December 31,
​ | ​ | 2022 | ​ | 2021
Audit fees and expenses (1) | ​ | $ | 605,349 | ​ | $ | 376,123

(1) | Audit fees and expenses were for professional services rendered for the audit and reviews of the consolidated financial statements of the Company, professional services rendered for issuance of consents and assistance with review of documents filed with the SEC.

The Audit Committee has adopted procedures for pre-approving all audit and non-audit services provided by the independent registered public accounting firm, including the fees and terms of such services. These procedures include reviewing detailed back-up documentation for audit and permitted non-audit services. The documentation includes a description of, and a budgeted amount for, particular categories of non-audit services that are recurring in nature and therefore anticipated at the time that the budget is submitted. Audit Committee approval is required to exceed the pre-approved amount for a particular category of non-audit services and to engage the independent registered public accounting firm for any non-audit services not included in those pre-approved amounts. For both types of pre-approval, the Audit Committee considers whether such services are consistent with the rules on auditor independence promulgated by the SEC and the PCAOB. The Audit Committee also considers whether the independent registered public accounting firm is best positioned to provide the most effective and efficient service, based on such reasons as the auditor’s familiarity with our business, people, culture, accounting systems, risk profile, and whether the services enhance our ability to manage or control risks, and improve audit quality. The Audit Committee may form and delegate pre-approval authority to subcommittees consisting of one or more members of the Audit Committee, and such subcommittees must report any pre-approval decisions to the Audit Committee at its next scheduled meeting. All of the services provided by the independent registered public accounting firm were pre-approved by the Audit Committee.

Report of Independent Registered Public Accounting Firm

Shareholders and Board of Directors

Nighthawk Biosciences, Inc.

Morrisville, North Carolina

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Nighthawk Biosciences, Inc. (the “Company”) as of December 31, 2022 and 2021, the related consolidated statements of operations and comprehensive loss, stockholders’ equity, and cash flows for the years then ended, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at December 31, 2022 and 2021, and the results of its operations and its cash flows for the years then ended, in conformity with accounting principles generally accepted in the United States of America.

Going Concern Uncertainty

The accompanying consolidated financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 2 to the consolidated financial statements, the Company has suffered recurring losses from operations and not generated significant revenue or positive cash flows from operations. These factors raise substantial doubt about the Company’s ability to continue as a going concern. Management’s plans in regard to these matters are also described in Note 2. The consolidated financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s consolidated financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matters

The critical audit matters communicated below are matters arising from the current period audit of the consolidated financial statements that were communicated or required to be communicated to the audit committee and that: (1) relate to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matters below, providing separate opinions on the critical audit matters or on the accounts or disclosures to which they relate.

Elusys Acquisition - Valuation of Developed Technology

As described in Note 5 to the Company’s consolidated financial statements, the Company acquired Elusys Therapeutics, LLC (“Elusys”) on April 18, 2022. The acquisition of Elusys was accounted for as a business combination and reflects the application of acquisition accounting in accordance with ASC 805, Business Combinations. The assets acquired from Elusys, including identifiable intangible assets, and liabilities assumed, were recorded at their preliminary estimated fair values with the excess purchase price assigned to goodwill. In connection with the acquisition of Elusys, the Company recorded a definite lived intangible asset of $9.7 million comprised of the ANTHIM® formulation. Determining the fair value of this intangible asset is judgmental in nature and involves the use of significant estimates and assumptions.

We identified the estimated fair value of the ANTHIM® formulation as a critical audit matter. The estimation of the fair value of the intangible asset acquired required management to make complex judgments with respect to the Company’s forecast of future cash flows derived from ANTHIM® and a risk adjusted discount rate. Auditing these assumptions required increased auditor judgement and effort, including the use of valuation specialists.

The primary procedures we performed to address this critical audit matter included:

| • | Evaluating the reasonableness of the cash flow assumptions used to estimate the acquisition date fair value of the ANTHIM® formulation by i) comparing forecasts of future revenues and operating expenses to historical performance of Elusys, and ii) assessing the likelihood of achieving the forecasted revenue.

| • | Utilizing professionals with specialized skills and knowledge in fair value measurements to assist in testing the accuracy of the Company’s calculation and assessing the reasonableness of the discount rate selected.

Elusys Acquisition - Valuation of Elusys Earn Out

As described in Notes 2 and 5 to the Company’s consolidated financial statements, the purchase consideration related to the acquisition of Elusys was approximately $42.9 million which included an earn out liability of $5.9 million. The earn out liability is measured at its estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations and comprehensive loss. The earn out liability is measured using a discounted cash flow model utilizing significant unobservable inputs including future revenue projections and an estimated discount rate. At December 31, 2022, the Elusys earn out liability was remeasured to fair value of $5.3 million and the Company recorded a $0.6 million gain on the change in fair value of the earn out liability.

We identified the estimation of the fair value of the Elusys earn out liability as of the acquisition date and the balance sheet date to be a critical audit matter. The estimation of the earn out liability at each date required management to make complex judgments with respect to future revenue projections derived from the ANTHIM® formulation and discount rates. Auditing these assumptions required increased auditor judgement and effort, including the use of valuation specialists.

The primary procedures we performed to address this critical audit matter included:

| • | Evaluating the reasonableness of management’s judgments with respect to future revenue projections derived from the ANTHIM® formulation used to estimate the value of the earnout liability at each date by i) comparing forecasts of future revenues to historical performance of Elusys and ii) assessing the likelihood of achieving the forecasted revenue.

| • | Utilizing professionals with specialized skills and knowledge in fair value measurements to assist in testing the accuracy of the Company’s calculation and assessing the reasonableness of the discount rate selected.

Goodwill Impairment Testing – Elusys Reporting Unit

As described in Notes 2, 5 and 8 to the Company’s consolidated financial statements, the Company recorded $3.6 million of goodwill in connection with the acquisition of Elusys. The Company tests goodwill for impairment at the reporting until level annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The Company records a goodwill impairment charge if a reporting unit’s carrying value exceeds its fair value. During the fourth quarter of 2022, due to a sustained a decline in quoted market price of its common stock, the Company performed an interim impairment analysis over the Elusys reporting unit using the income approach. Through quantitative analysis, the Company determined the carrying value was not in excess of its estimated fair value and therefore no impairment charge was recorded.

We identified the determination of the fair value of the Elusys reporting unit as a critical audit matter. The estimation of the fair value of the reporting unit required management to make complex judgments with respect to the Company’s forecast of future cash flows within the reporting unit and a risk adjusted discount rate. Auditing these assumptions required increased auditor judgement and effort, including the use of valuation specialists.

The primary procedures we performed to address this critical audit matter included:

| • | Evaluating the reasonableness of the cash flow assumptions used to estimate the fair value of the reporting unit by i) comparing forecasts of future revenues and operating expenses to historical results, and ii) assessing the likelihood of achieving the forecasted revenue.

| • | Utilizing professionals with specialized skills and knowledge in fair value measurements to assist in testing the accuracy of the Company’s calculation and assessing the reasonableness of the discount rate selected.

Scorpius Lease

As described in Note 14 of the consolidated financial statements, in October 2021, the Company, through its subsidiary Scorpius BioManufacturing, Inc. (“Scorpius”), entered into a lease agreement for a facility to be used for general office, laboratory, research, analytical, and/or biomanufacturing purposes. The facility is being leased from a nonprofit entity investing in the building such that investments made by both the landlord and Scorpius may qualify for certain tax credits. Scorpius agreed that all investments and expenditures qualifying under the relevant tax credit programs would be purchased by the landlord and Scorpius would reimburse the landlord for these payments. As of December 31, 2022, Scorpius had reimbursed the landlord $24.3 million. Scorpius recorded a finance lease right-of-use asset of $15.1 million and lease liability of $5.1 million for this lease.

We identified the accounting for the Scorpius lease as a critical audit matter. Accounting for the Scorpius lease required management to make significant judgements with respect to the fair value of the leased facility and its impact on lease classification, the identification of the accounting owner of investments made in the facility, the treatment of lease incentives related to the tax incentives received by the landlord, and the estimation of the incremental borrowing rate. Auditing these judgments required increased audit effort including involving professionals with specialized skills in technical lease accounting and valuation.

| • | Utilizing professionals with specialized knowledge and experience in technical lease accounting to assist in the identification of the accounting owner of the investments made in the facility and evaluation of the impact of the lease incentives on the determination of lease classification and overall accounting for the lease.

| • | Utilizing professionals with specialized knowledge and skill in real estate valuations to assist in assessing the reasonableness of the Company’s estimation of the fair value of the underlying assets used in determination of the lease classification.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Organization

NightHawk Biosciences is a fully integrated biopharmaceutical company specializing in the end-to-end development and commercialization of innovative medical countermeasures that combat unmet and emerging biothreats. NightHawk’s discovery subsidiary, Skunkworx Bio, enhances NightHawk’s ability to identify candidates for drug development, while NightHawk’s biomanufacturing subsidiary, Scorpius BioManufacturing, Inc. (“Scorpius”), provides internal bioanalytical, process development and biomanufacturing capabilities that support NightHawk’s pipeline and commercial assets. Elusys Therapeutics, Inc. (“Elusys”) supports NightHawk’s goal of innovating in the biodefense sector by adding expertise in developing and delivering life-saving medical countermeasures, including our commercially available anthrax antitoxin ANTHIM® (obiltoxaximab ). Collectively, this ecosystem is designed to increase the efficiency of drug development and accelerate the capability to combat infectious disease.

During the past year, NightHawk’s priorities have shifted to biodefense and biomanufacturing capabilities resulting in a refocusing of resources and efforts towards biodefense and biomanufacturing and away from clinical-stage oncology assets including HS-110 and PTX-35.

Effective May 3, 2022, Heat Biologics, Inc. changed its name to NightHawk Biosciences, Inc. (the “Company”) by filing a Certificate of Amendment (the “Certificate of Amendment”) to its Third Amended and Restated Certificate of Incorporation with the Secretary of State of the State of Delaware

2. Summary of Significant Accounting Policies

Principles of Consolidation

The consolidated financial statements include the accounts of NightHawk Biosciences, Inc., and its subsidiaries (“the Company”), Pelican Therapeutics, Inc. (“Pelican”), Heat Biologics I, Inc. (“Heat I”), Heat Biologics III, Inc. (“Heat III”), Heat Biologics IV, Inc. (“Heat IV”), Heat Biologics GmbH, Heat Biologics Australia Pty Ltd., Zolovax, Inc., Skunkworx Bio, Inc. (formerly known as Delphi Therapeutics, Inc.), Scorpius BioManufacturing, Inc. (“Scorpius”) (formerly Scorpion Biological Services, Inc), Blackhawk Bio, Inc., Abacus Biotech, Inc., and Elusys Therapeutics, Inc. (“Elusys”). The functional currency of the entities located outside the United States of America (the foreign entities) is the applicable local currency of the foreign entities. Assets and liabilities of the foreign entities are translated at period-end exchange rates. Statement of operations accounts are translated at the average exchange rate during the period. The effects of foreign currency translation adjustments are included in other comprehensive loss, which is a component of accumulated other comprehensive loss in stockholders’ equity. All significant intercompany accounts and transactions have been eliminated in consolidation. The December 31, 2022 and 2021 year-end financials include an 85% controlling interest in Pelican. NightHawk accounts for its less than 100% interest in the consolidated financial statements in accordance with U.S. Generally Accepted Accounting Principles (“GAAP”). Accordingly, the Company presents non-controlling interest as a component of stockholders’ equity on its consolidated balance sheets and reports non-controlling interest net loss under the heading “net loss – non-controlling interest” in the consolidated statements of operations and comprehensive loss.

Restatement of Prior Quarterly 2022 Financial Statements (Unaudited)

During the preparation and review of its annual tax provision for the year ended December 31, 2022, it was determined that the Company made certain errors in the manner in which it recognized a deferred tax asset valuation allowance related to the acquisition of Elusys Therapeutics, Inc. (“Elusys”). Under ASC 740 – Income Taxes, the release of an acquirer’s valuation allowance on the acquirer’s (i.e., the Company’s) deferred tax assets in the amount of the acquired Elusys deferred tax liability (“DTL”) should be recorded as an income tax benefit and be reported as a component of net loss in the unaudited consolidated statement of operations and comprehensive loss. The DTL was recorded in the unaudited consolidated balance sheet at June 30, 2022 and September 30, 2022, however the DTL was not and should have been recorded as an income tax benefit within the unaudited consolidated statement of operations and comprehensive loss for the quarter ending June 30, 2022. This error resulted in net loss being overstated by $3.3 million for the three and six months ended June 30, 2022 and the nine months ended September 30, 2022. In accordance with Staff Accounting Bulletin

NIGHTHAWK BIOSCIENCES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

("SAB") No. 99, Materiality, and SAB No. 108, Considering the Effects of Prior Year Misstatements when Quantifying Misstatements in Current Year Financial Statements, the Company evaluated these misstatements, and based on an analysis of quantitative and qualitative factors, determined that the impact of these misstatements was material to its interim reporting periods ended June 30, and September 30, 2022.

Accordingly, the Company has restated its unaudited consolidated financial statements for the interim reporting periods for the three- and six-months ended June 30, 2022, and three- and nine- months ended September 30, 2022, respectively, and has included that restated unaudited financial information within this annual report. There is no cumulative impact to the Company’s full-year 2022 financial statements as a result of this restatement. Restatement of amounts in previously filed unaudited quarterly financial statements are reflected in Note 17- Restatement of Interim Financial Statements. Because we are restating prior periods, we are also reflecting another immaterial adjustment related to an additional error that was identified during this process. The Company recorded a measurement period adjustment in the third quarter which reduced the acquired definite lived intangible asset value by approximately $1.5 million. Given that the DTL is calculated using the acquired intangible asset value, the Company should have also adjusted the purchase price allocation by recording a decrease to goodwill of $0.3 million. This also reduces the deferred tax assets utilized to offset the acquired DTL and thus increases the valuation allowance. This is adjusted through a decrease in the income tax benefit recognized for the three and nine-months ended September 30, 2022 of $0.3 million. This is adjusted in the restated unaudited consolidated balance sheet at September 30, 2022 and the restated unaudited statement of operations and comprehensive loss for the quarter ending September 30, 2022.

Going Concern Uncertainty

The Company has an accumulated deficit of $209.2 million as of December 31, 2022 and a net loss of approximately $43.9 million for the year ended December 31, 2022 and has not generated significant revenue or positive cash flows from operations. The Company expects to incur significant expenses and continued losses from operations for the foreseeable future. The Company expects its expenses to increase in connection with its ongoing activities, particularly as the Company ramps up operations in its in-house bioanalytic, process development and manufacturing facility in San Antonio, TX, expands its infectious disease/biological threat program, and continues to support the development of, and commencement of operations at, a new biodefense-focused large molecule and biologics biomanufacturing facility in Manhattan, Kansas. As of December 31, 2022, a lease has not been executed for this Kansas facility. In addition, any new business ventures that the Company may engage in are likely to require commitments of capital. Accordingly, the Company will in the future need to obtain substantial additional funding in connection with its planned operations. Adequate additional financing may not be available to the Company on acceptable terms, or at all. If the Company is unable to raise capital when needed or on attractive terms, it would be forced to delay, reduce or eliminate its research and development programs, any future commercialization efforts or the manufacturing services it plans to provide. To meet its capital needs, the Company intends to continue to consider multiple alternatives, including, but not limited to, additional equity financings such as sales of its common stock under at-the-market offerings, debt financings, partnerships, grants, funding collaborations and other funding transactions, if any are available. As of December 31, 2022, the Company had approximately $44.3 million in cash and cash equivalents and short-term investments. The Company will need to generate significant revenues to achieve profitability, and it may never do so. Management has determined that there is substantial doubt about the Company's ability to continue as a going concern within one year after the consolidated financial statements are issued.

​

Risk and Uncertainties

The Company’s future results of operations involve a number of risks and uncertainties. Factors that could affect the Company’s future operating results and cause actual results to vary materially from expectations include, but are not limited to, uncertainty of results of clinical trials and reaching milestones, uncertainty of market acceptance of the Company’s products, competition from substitute products and larger companies, securing and protecting proprietary technology, strategic relationships and dependence on key individuals and sole source suppliers.

The Company depends on third-party suppliers for key materials and services used in research and development, as well as manufacturing processes, and is subject to certain risks related to the loss of these third-party suppliers or their inability

F-11

Table of Contents

NIGHTHAWK BIOSCIENCES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

to supply adequate materials and services. The Company does not control the manufacturing processes of the contract development and manufacturing organizations, or CDMOs, with whom it contracts and is dependent on for the production of its therapeutic candidates in accordance with relevant regulations (such as current Good Manufacturing Practices, or cGMP), which include, among other things, quality control, quality assurance and the maintenance of records and documentation.

Use of Estimates

The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the amounts reported in the financial statements and accompanying notes. Estimates are used for, but not limited to, useful lives of fixed assets, contingent consideration, valuation of goodwill and other intangible assets, income taxes, valuation of warrant liabilities, stock-based compensation, right-of-use assets and lease liabilities, and useful lives of intangible assets. Actual results may differ from those estimates.

Reclassification

Certain prior year amounts have been reclassified to conform to the current year presentation in the consolidated financial statements and accompanying notes to the consolidated financial statements including the IPR&D impairment, which was previously included in research and development expense and is now presented as a separate line item on the Company's consolidated statements of operations and comprehensive loss.

Segments

Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker in making decisions regarding resource allocation and assessing performance. To date, the Company has viewed the operations and managed the business as one segment.

Cash and Cash Equivalents

The Company considers all cash and other highly liquid investments with initial maturities from the date of purchase of three months or less to be cash and cash equivalents.

Short-term Investments

The Company’s short-term investments consist of equity securities and are carried at fair value. Unrealized gains and losses on securities are reported in the consolidated statements of operations and comprehensive loss. The Company classifies marketable equity investments available to fund current operations as current assets on its consolidated balance sheets.

Derivative Financial Instruments

The Company has issued common stock warrants in connection with the execution of certain equity financings. The fair value of the warrants, which were deemed to be derivative instruments, was recorded as a derivative liability under the provisions of ASC 815 Derivatives and Hedging because they are not considered indexed to the Company’s own stock. Subsequently, the liability is adjusted to fair value as of the end of each reporting period and the changes in fair value of derivative liabilities are recorded in the consolidated statements of operations and comprehensive loss under the caption “Change in fair value of warrant liability.”

The fair value of the warrants, including the warrants issued in connection with the January 2020 common stock offering and recorded as liability, was determined using the Monte Carlo simulation model, which is deemed to be an appropriate model due to the terms of the warrants issued.

NIGHTHAWK BIOSCIENCES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

Concentration of Credit Risk

At times, cash balances may exceed the Federal Deposit Insurance Corporation (“FDIC”) insurable limits. The Company has never experienced any losses related to these balances. As of December 31, 2022, and 2021, cash amounts in excess of $250,000 were not fully insured. The uninsured cash balance as of December 31, 2022 was $7.8 million. The Company does not believe it is exposed to significant credit risk on cash and cash equivalents.

Property and Equipment

Property and equipment are stated at cost and are capitalized. Depreciation is calculated using the straight-line method and is based on estimated useful lives of five years for lab equipment, three years for computer equipment, eight years for furniture and fixtures and vehicles, and five to eight years for leasehold improvements.

Leases

​

The Company leases office space and certain equipment under non-cancelable lease agreements. The Company applies the accounting guidance in ASC 842, Leases. As such, the Company assesses all arrangements that convey the right to control the use of property, plant and equipment at inception to determine if it is, or contains, a lease based on the unique facts and circumstances present in that arrangement. For those leases identified, the Company determines the lease classification, recognition, and measurement at the lease commencement date. For arrangements that contain a lease the Company: (i) identifies lease and non-lease components; (ii) determines the consideration in the contract; (iii) determines whether the lease is an operating or financing lease; and (iv) recognizes lease Right of Use (“ROU”) assets and corresponding lease liabilities. Lease liabilities are recorded based on the present value of lease payments over the expected lease term. The corresponding ROU asset is measured from the initial lease liability, adjusted by (i) accrued or prepaid rents; (ii) remaining unamortized initial direct costs and lease incentives; and (iii) any impairments of the ROU asset.

​

Fixed lease payments on operating leases are recognized over the expected term of the lease on a straight-line basis. Variable lease expenses that are not considered fixed are expensed as incurred. Fixed and variable lease expense on operating leases is recognized within operating expenses within the accompanying consolidated statements of operations and comprehensive loss.

​

The interest rate implicit in the Company’s lease contracts is typically not readily determinable and as such, the Company uses its incremental borrowing rate based on the information available at the lease commencement date, which represents an internally developed rate that would be incurred to borrow, on a collateralized basis, over a similar term, an amount equal to the lease payments in a similar economic environment.

Other Assets

In conjunction with a lease agreement further discussed in Note 14, Scorpius has made reimbursement payments to the lessor, Merchants Ice II, LLC, for costs incurred in conjunction with the leased site. Merchants Ice II, LLC is a nonprofit entity investing in the building with the intention to encourage development of emerging technologies. As a result, investments made to the building could generate tax incentives under the New Market Tax Credit (“NMTC”) program. Scorpius agreed that all investments and expenditures qualifying under the NMTC (i.e., certain equipment and building improvements) would be purchased by Merchants Ice II, LLC to generate the largest possible tax incentive and Scorpius reimbursed Merchant Ice, LLC for these payments.

During the construction of the site, these payments were included in other assets on the consolidated balance sheets. On September 15, 2022, the lease commenced, and in accordance with ASC 842, the Company capitalized $13.2 million of payments to lab equipment and $10.2 million is included in the operating lease right-of-use asset.

Net Loss per Share

Basic net loss per share is computed by dividing net loss by the weighted average number of common shares outstanding during each year. Fully diluted net loss per share is computed using the weighted average number of common shares and dilutive securities outstanding during each year. Dilutive securities having an anti-dilutive effect on diluted loss per share are excluded from the calculation.

Income Tax

Income taxes are accounted for using the asset and liability method. Deferred tax assets and liabilities are recognized for the future tax consequences attributable to temporary differences between the financial statements carrying amounts of assets and liabilities and their respective tax bases, operating loss carryforwards, and tax credit carryforwards. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in the years in which those temporary differences are expected to be recovered or settled. The effect on deferred tax assets and liabilities of a change in tax rates is recognized in income in the period that includes the enactment date.

In accordance with ASC 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of December 31, 2022 and 2021, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying consolidated statements of operations. As of December 31, 2022 and 2021, the Company had no such accruals.

Stock-Based Compensation

The Company accounts for stock-based compensation arrangements with employees and non-employee directors using a fair value method that requires the recognition of compensation expense for costs related to all stock-based payments, including stock options and restricted stock units. The fair value method requires the Company to estimate the fair value of stock-based payment awards on the date of grant using an option pricing model. The fair value of restricted stock units is estimated based on the closing price of the Company’s stock on the date of grant, and for the purposes of expense recognition, the total new number of shares expected to vest is adjusted for forfeitures as they occur. The Company settles exercises of stock options with newly issued shares of its common stock.

Stock-based compensation costs are based on the fair value of the underlying option calculated using the Black-Scholes-Merton option pricing model on the date of grant for stock options and are recognized as expense on a straight-line basis over the requisite service period, which is the vesting period. Determining the appropriate fair value model and related assumptions requires judgment, including estimating stock price volatility, and expected term. The expected volatility rates are estimated based on average historical stock price volatility of its own data plus an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms. The expected term for the years ended December 31, 2022 and 2021 represents the average time that options are expected to be outstanding based on the average of the vesting term and the contractual term of the option. We account for forfeitures as they occur. The Company has not paid dividends and does not anticipate paying a cash dividend in the foreseeable future and, accordingly, uses an expected dividend yield of zero. The risk-free interest rate is based on the rate of U.S. Treasury securities with maturities consistent with the estimated expected term of the awards.

Net Loss Attributable to Non-controlling Interests

Net loss attributable to non-controlling interests is the result of the Company’s consolidation of subsidiaries of which it does not own 100%. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican, a related party prior to acquisition, for 35,000 shares of the Company’s common stock. The stock exchange resulted in the Company owning

F-14

Table of Contents

NIGHTHAWK BIOSCIENCES, INC.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

100% of Heat I, Inc. and increasing its controlling ownership in Pelican from 80% to 85%. The Company’s net loss attributable to non-controlling interests relates to the 15% ownership of Pelican that Heat does not own as of December 31, 2022 and 2021.

Deferred Revenue

Deferred revenue is comprised of an exclusive license agreement with Shattuck Labs, Inc. (“Shattuck”) and process development customer deposits received in advance of our fulfillment of performance obligations.

License Agreements

The Company has licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by the Company. Shattuck paid the Company an initial license fee of $50,000 in June 2016 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones, and royalties upon sales of commercial products. In-as-much as the technology that the Company out-licensed is in the early stages of development and there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any revenue from Shattuck.

Process Development

Process development deferred revenue generally represents customer payments received in advance of the Company’s fulfillment of performance obligations associated with the custom development of a manufacturing process and analytical methods for a customer’s product. As of December 31, 2022 there was $1.6 million of deferred revenue related to process development.

Revenue Recognition

The Company applies ASC 606, Revenue from Contracts with Customers. Under ASC 606, revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To determine revenue recognition for arrangements that an entity determines are within the scope of ASC 606, the Company performs the following five steps: (i) identify the contract(s) with a customer; (ii) identify the performance obligations in the contract; (iii) determine the transaction price; (iv) allocate the transaction price to performance obligations in the contract; and (v) recognize revenue when (or as) the entity satisfies a performance obligation.

Revenue is recognized when a customer obtains control of promised goods or services, in an amount that reflects the consideration which the entity expects to receive in exchange for those goods or services. To the extent the transaction price includes variable consideration, the Company estimates the amount of variable consideration that should be included in the transaction price using the most likely method based on historical experience as well as applicable information currently available.

Product Sales

The Company recognizes revenue from product sales when its performance obligation with its customers has been satisfied. The performance obligation is satisfied at a point in time when the Company’s customers obtain control of the product, which is typically upon acceptance of the product at the delivery site. The Company invoices its customers after acceptance of the product and invoice payments are generally due within 30 days of the invoice date. The Company records product sales net of any variable consideration, including refund rights. The Company uses the most likely amount method when estimating its variable consideration, unless terms are specified within contracts. The Company recognizes revenue to the extent that it is probable that a significant revenue reversal will not occur in a future period. These estimates may differ from actual consideration received. The Company evaluates these estimates to reflect known changes.

Grant Revenue

The Company recognizes revenue related to the Cancer Prevention and Research Institute of Texas (“CPRIT”) contract, which is being accounted for under Accounting Standards Update (“ASU”) No. 2018-08, Not-For-Profit Entities (Topic 958): Clarifying the Scope and the Accounting Guidance for Contributions Received and Contributions Made, as a conditional non-exchange contribution.

The CPRIT grant covers the period from June 1, 2017 through May 31, 2022, for a total grant award of up to $15.2 million. CPRIT advances grant funds upon request by the Company consistent with the agreed upon amounts and schedules as provided in the contract. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and the third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million will be paid, on a reimbursement basis, after the Company has fulfilled every objective of the final goals of the grant. Funds received are reflected in deferred revenue as a liability until revenue is earned. Grant revenue is recognized when qualifying costs are incurred. When grant funds are received after costs have been incurred, the Company records revenue and a corresponding grants receivable until grant funds are received. As of December 31, 2022, all $15.2 million has been recognized.

On January 7, 2020, the Company was awarded a grant of up to $0.2 million from the National Institute of Allergy and Infectious Diseases, which is under the umbrella of the National Institutes of Health (“NIH”). The NIH grant provides funding for continued development of the Company’s technologies for PTX-35. The grant funds will be made available by the NIH to the Company as allowable expenses are incurred. For the year ended December 31, 2022, the Company incurred $0.04 million of allowable expenses, respectively, under the NIH grant and recognized the corresponding revenue. For the year ended December 31, 2021, the Company incurred approximately $0.03 million of allowable expenses under the NIH grant and recognized a corresponding amount of grant revenues.

Process development revenue

Process development revenue generally represents revenue from services associated with the custom development of a manufacturing process and analytical methods for a customer’s product. Process development revenue is recognized over time utilizing an output method by tracking the progress toward completion by measuring outputs to date relative to total estimated outputs needed to satisfy the performance obligation. Under a process development contract, the customer owns the product details and process, which has no alternative use. These process development projects are customized to each customer to meet its specifications and typically includes only one performance obligation. Each process represents a distinct service that is sold separately and has stand-alone value to the customer. The customer also retains control of its product as the product is being created or enhanced by our services and can make changes to its process or specifications upon request. Under these agreements, we are entitled to consideration for progress to date that includes an element of profit margin. As of December 31, 2022, the Company has not recognized any process development revenue.

Business Combinations

The accounting for our business combinations consists of allocating the purchase price to tangible and intangible assets acquired and liabilities assumed based on their estimated fair values, with the excess recorded as goodwill. We have up to one year from the acquisition date to use information as of each acquisition date to adjust the fair value of the acquired assets and liabilities, which may result in material changes to their recorded values with an offsetting adjustment to goodwill. Determining the fair value of assets acquired and liabilities assumed requires significant judgment, which includes, among other factors, analysis of historical performance and estimates of future performance. In some cases, we have used discounted cash flow analyses, which were based on our best estimate of future revenue, earnings and cash flows as well as our discount rate, adjusted for risk (see Note 5).

Goodwill and Intangible Assets

The Company classifies intangible assets into three categories: (1) intangible assets with definite lives subject to amortization, (2) intangible assets with indefinite lives not subject to amortization and (3) goodwill. The Company determines the useful lives of definite-lived intangible assets after considering specific facts and circumstances related to each intangible asset. Factors the Company considers when determining useful lives include the contractual term of any agreement related to the asset, the historical performance of the asset, and other economic facts; including competition and specific market conditions. Intangible assets that are deemed to have definite lives are amortized, primarily on a straight-line basis, over their estimated useful lives. Intangible assets that are deemed to have indefinite lives, including goodwill, are reviewed for impairment annually, or more frequently if events or changes in circumstances indicate that the asset might be impaired. The impairment test for indefinite-lived intangibles, other than goodwill, consists of a comparison of the fair value of the intangible asset with its carrying amount. If the carrying amount exceeds the fair value, an impairment charge is recognized in an amount equal to that excess. Indefinite-lived intangible assets, such as goodwill, are not amortized. The Company tests the carrying amounts of goodwill for recoverability on an annual basis or when events or changes in circumstances indicate a potential impairment exists, using a fair value-based test. The Company records a goodwill impairment charge if a reporting unit’s carrying value exceeds its fair value.

In-process research and development (“IPR&D”) assets are considered to be indefinite-lived until the completion or abandonment of the associated research and development projects. IPR&D assets represent the fair value assigned to technologies that the Company acquires, which at the time of acquisition have not reached technological feasibility and have no alternative future use. During the period that the assets are considered indefinite-lived, they are tested for impairment on an annual basis, or more frequently if the Company becomes aware of any events occurring or changes in circumstances that indicate that the fair value of the IPR&D assets are less than their carrying amounts. If and when development is complete, which generally occurs upon regulatory approval and the ability to commercialize products associated with the IPR&D assets, these assets are then deemed definite-lived and are amortized based on their estimated useful lives at that point in time. If development is terminated or abandoned, the Company may have a full or partial impairment charge related to the IPR&D assets, calculated as the excess of carrying value of the IPR&D assets over fair value. See Note 8 regarding impairment at December 31, 2022.

Contingent Consideration

Consideration paid in a business combination may include potential future payments that are contingent upon the acquired business achieving certain milestones in the future (“contingent consideration”). Contingent consideration liabilities are measured at their estimated fair value as of the date of acquisition, with subsequent changes in fair value recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration is measured at fair value using a discounted cash flow model utilizing significant unobservable inputs including the probability of achieving each of the potential milestones, the estimated timing of milestone achievement, and an estimated discount rate associated with the risks of the expected cash flows attributable to the various milestones. The milestone payments will be made upon the achievement of milestones as well as royalty payments. Subsequent to the date of acquisition, the Company reassesses the actual consideration earned and the probability-weighted future earn-out payments at each balance sheet date. Any adjustment to the contingent consideration liability will be recorded in the consolidated statements of operations and comprehensive loss. Contingent consideration liabilities expected to be settled within 12 months after the balance sheet date are presented in current liabilities, with the non-current portion recorded under long term liabilities in the consolidated balance sheets. During the year ended December 31, 2022, $3.3 million of contingent consideration related to Pelican was written off as PTX-35 will not continue on to a Phase 2 trial (see Note 4).

and outside service providers related to the development of the Company’s product candidates and other expenses relating to the design, development, and testing and enhancement of its product candidates.

Impact of Recently Issued Accounting Standards:

The Company has evaluated issued ASUs not yet adopted and believes the adoption of these standards will not have a material impact on its consolidated financial statements.

3. Short-Term Investments

Short-term investments consist of equity securities with a maturity of greater than three months and less than twelve months when acquired. The Company reports its securities at fair value as of December 31, 2022 and 2021. Unrealized losses on securities of $1.7 million and $0.8 million, respectively, are reported in the consolidated statements of operations and comprehensive loss for the years ended December 31, 2022 and 2021. Short-term investments at December 31, 2022 and 2021 consisted of mutual funds with fair values of $35.8 million and $88.3 million, respectively.

4. Fair Value of Financial Instruments

As a basis for determining the fair value of certain of the Company’s financial instruments, the Company utilizes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value as follows:

Level I – Observable inputs such as quoted prices in active markets for identical assets or liabilities.

Level II – Observable inputs, other than Level I prices, such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level III – Unobservable inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities.

This hierarchy requires the Company to use observable market data, when available, and to minimize the use of unobservable inputs when determining fair value. Assets and liabilities measured at fair value are classified in their entirety based on the lowest level of input that is significant to the fair value measurement. The Company’s assessment of the significance of a particular input to the entire fair value measurement requires management to make judgments and consider factors specific to the asset or liability. The Company’s cash equivalents are classified within Level I of the fair value hierarchy.

As of December 31, 2022 and 2021, the fair values of cash and cash equivalents, accounts payable, and accrued expenses approximated their carrying values because of the short-term nature of these assets or liabilities. The Company’s short-term investments consist of Level I securities which are comprised of highly liquid money market funds. The estimated fair value of the short-term investments was based on quoted market prices. There were no transfers between fair value hierarchy levels during the years ended December 31, 2022 or 2021.

The fair value of financial instruments measured on a recurring basis is as follows:

​

Balance at December 31, 2022 | ​ | $ | — | ​ | $ | 12,224,614 | ​

​

The change in the fair value of the contingent consideration of ($3,452,015) and $430,000 for the years ended December 31, 2022 and 2021, respectively, was primarily due to the effect of the change in discount rate, probability of achieving milestones, passage of time on the fair value measurement and discontinuation of the PTX-35 trial, thus leading to the write-off of the Pelican contingent consideration. Adjustments associated with the change in fair value of contingent consideration are included in the Company’s consolidated statement of operations and comprehensive loss.

​

The Company measures certain non-financial assets on a non-recurring basis, including goodwill and in-process R&D and definite lived intangibles. As a result of those measurements, during the year ended December 31, 2022, in-process R&D with a total carrying value of $3.5 million was fully impaired with an impairment charge of $3.5 million. The full impairment of the in-process R&D was a result of the Company deciding to terminate any further development of PTX-35, Pelican’s lead product candidate. During the year ended December 31, 2021, goodwill with a total carrying value of $1.5 million was written down and an impairment charge of $1.5 million was recorded. During the same period, in-process R&D with a total carrying value of $5.9 million was written down to its estimated fair value of $3.5 million and an impairment charge of $2.4 million. Impairment analysis requires significant judgments, including primarily the estimation of future development costs, the probability of success in various phases of its development programs, potential post-launch cash flows and a risk-adjusted weighted average cost of capital.

​

Assumptions related to future operating performance are based on management’s annual and ongoing budgeting, forecasting and planning processes and represent our best estimate of the future results of our operations as of a point in time. These estimates are subject to many assumptions, such as the economic environments in which we operate, demand for the products and competitor actions. Estimated future cash flows are discounted to present value using a market participant, weighted average cost of capital, which considers the risk inherent in the probability adjusted future cash flows from each product. The financial and credit market volatility directly impacts certain inputs and assumptions used to develop the weighted average cost of capital such as the risk-free interest rate, industry beta, debt interest rate and our market capital structure. These assumptions are based on significant inputs not observable in the market and thus represent Level 3 measurements within the fair value hierarchy. The use of different inputs and assumptions could increase or decrease our estimated discounted future cash flows, the resulting estimated fair values and the amounts of related goodwill impairments, if any.

5. Acquisitions

Pelican Therapeutics

​

In 2017, the Company consummated the acquisition of 80% of the outstanding equity of Pelican, a related party, and Pelican became a majority owned subsidiary of the Company. During the quarter ended March 31, 2018, cash consideration of approximately $300,000 was distributed to the participating Pelican stockholders and the remainder of approximately $200,000 for certain Pelican liabilities not satisfied was recognized as other income in the statements of

operations and comprehensive loss for the period. In October 2018, the Company entered into an agreement with the University of Miami (“UM”) whereby UM exchanged its shares of stock in the Company’s subsidiaries, Heat I, Inc. and Pelican. The stock exchange resulted in Heat increasing its controlling ownership in Pelican from 80% to 85%.

​

Under the agreement, the Company was also obligated to make future payments based on the achievement of certain clinical and commercialization milestones, as well as low single digit royalty payments and payments upon receipt of sublicensing income. However, due to the discontinuation of PTX-35 no future milestone payments are expected to be made. The goodwill and in-process R&D resulting from the acquisiton were fully impaired as of December 31, 2022 (see Note 8).

​

Elusys Therapeutics

​

On April 18, 2022 (“Closing Date”), the Company closed on the acquisition of Elusys. NightHawk paid at the closing a cash upfront payment of $3,000,000 to the former owners (“Sellers”) of Elusys. NightHawk is obligated to pay the Sellers $2,000,000 of deferred cash consideration (“Merger Consideration”) at the same time that the payment of the receivable consideration is to be distributed to the Sellers as described below, which was paid in the second quarter of 2022. Earn out payments will be paid to the sellers for a period of 12 years from the date of the closing equal to 10% of the gross dollar amount of payments received during each one year period during such twelve year period with respect to any sale, license or commercialization anywhere in the world of ANTHIM® that either: (a) occurs during the first nine years after the closing date in any respect; or (b) occurs thereafter pursuant to any contract, agreement, commitment or order that is placed, granted, awarded, or entered into during the first nine years after the Closing Date.

Per the Merger Agreement, upon collection of the Elusys contract receivables of $24.5 million, NightHawk will remit payment of $22.3 million (the “Receivable Consideration”) to the Sellers. In April 2022, $20.8 million was remitted to the sellers less a hold back of $1.5 million related to future fulfillment cost. Elusys is expected to receive additional revenue from the future fulfillment of an existing U.S. Government contract, and NightHawk has agreed to fulfill the future obligations of Elusys under such contract and pass through and distribute to the Sellers the payments received under such contract minus the costs associated with such fulfillment obligations, subject to certain adjustments to the Merger Consideration specified in the Merger Agreement, including income taxes payable with respect to such payments (the “Contract Deferred Consideration”). The Merger Agreement further provides that 80% of any amounts paid to and received by Elusys (the “Additional Earn Out”) after the Closing Date and prior to June 30, 2023, shall be paid to the Sellers, subject to certain adjustments specified in the Merger Agreement.

The Company acquired Elusys to expand its role in the biodefense space, complementing NightHawk’s focus to target emerging biological threats. NightHawk plans to leverage Elusys’ existing relationships and distribution channels. In addition, NightHawk expects to leverage the capabilities of its planned Scorpius biomanufacturing facility in Manhattan, Kansas, which will enable the Company to manufacture these therapies internally and therefore benefit from significant operating synergies, as well as enhanced oversight, quality control, and speed to market. The Company is also exploring opportunities to expand ANTHIM® distribution abroad. The acquisition is aligned with NightHawk’s vision to establish a fully-integrated ecosystem to deliver medical innovations faster, better, and more efficiently.

The fair value of the purchase consideration was approximately $42.9 million. The purchase consideration consists of $3.0 million in cash and $2.0 million in deferred cash consideration, and the preliminary estimated fair value of the contingent and deferred consideration liabilities related to the receivable consideration, contract deferred consideration, earn out and additional earn out totaling $37.9 million. The preliminary valuation of the contract deferred consideration and earn out liabilities were valued using a discounted cash flow analysis that utilized discount rates of 24% and 14%, respectively. The preliminary value of the additional earn out liability was calculated as 80% of the estimated gross sales price of 1,500 pre-filled vials of ANTHIM®, less estimated fulfillment costs to be incurred. The value of the receivable consideration was equal to the value of the contract receivablesacquired, less holdback expenses, as this liability was settled within 30 days of the Closing Date.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

The acquisition of Elusys was accounted for as a business combination and reflects the application of acquisition accounting in accordance with ASC 805, Business Combinations. The acquired Elusys’ assets, including identifiable intangible assets and liabilities assumed, have been recorded at their estimated fair values with the excess purchase price assigned to goodwill. The recognition of goodwill is largely attributed to the value paid for Elusys’ capabilities, which will broaden NightHawk’s role in the biodefense space. The goodwill recorded for this transaction is valued at $3.3 million and will be deductible for tax purposes over 15 years.

The preliminary purchase price of $42.9 million has been allocated to the underlying assets and liabilities based on their estimated fair value at the date of acquisition. The excess of the purchase price over the fair value of assets acquired and liabilities assumed was recorded as goodwill. As we are still in the process of reviewing the fair value of the assets acquired and liabilities assumed, the purchase price allocation for Elusys is not complete as of December 31, 2022. In accordance with ASC 805, Business Combinations, we will finalize our purchase price allocation within one year of the acquisition date.

circumstances that existed at the date of the transaction may change the amount and allocation of the purchase price. As such, the allocations for this transaction are preliminary estimates including deferred taxes, which may be subject to change within the measurement period.

During the three months ended September 30, 2022 the Company recognized a measurement period adjustment as a result of a change in forecast that related to the estimate of acquired assets resulting in a $1.5 million decrease in intangible assets, a $0.3 million decrease in the deferred tax liability and a $1.2 million decrease in goodwill. There were no other measurement period adjustments during the year.

​

In connection with the acquisition, the Company incurred one-time expenses consisting primarily of legal fees, accounting fees and consultant fees. For the year ended December 31, 2022, the Company incurred approximately $0.6 million of acquisition costs related to the Elusys transaction, which are included in general and administrative expenses in the consolidated statements of operations.

​

From the Elusys acquisition date through December 31, 2022, $6.0 million of total revenue and a net loss of $3.5 million associated with Elusys operations are included in the consolidated statements of operations and comprehensive loss for the year ended December 31, 2022. Upon achievement of the next milestone payment event, contingent consideration of $5.4 million is expected to be paid to Elusys’ shareholders by June 30, 2023.

​

Depreciation expense totaled $1.8 million and $0.4 million for the years ended December 31, 2022 and 2021, respectively.

8. Goodwill and other intangible assets

The Company performs an annual impairment test at the reporting unit level as of April 1st of each fiscal year or more frequently when an event occurs or circumstances change that indicate the carrying value may not be recoverable. As of April 1, 2022, the Company qualitatively assessed whether it is more likely than not that the respective fair value of the Company’s reporting units (NightHawk, Pelican, Elusys and Scorpius) were less than its carrying amount, including goodwill.

​

Pelican Goodwill and In-Process R&D

​

Goodwill of $2.2 million and in-process R&D of $5.9 million were recorded in connection with the acquisition of Pelican, as described in Note 4 and have been allocated to the Pelican reporting unit. During the fourth quarter of 2021, due to a sustained decline in the quoted market price of its common stock, the Company performed an interim impairment analysis using the income approach and in-process R&D with a total carrying value of $5.9 million was written down to its estimated fair value of $3.5 million and an impairment charge of $2.4 million during the fourth quarter of 2021 was recorded and goodwill in the amount of $1.5 million was fully impaired. During the third quarter of 2022, the Company elected to terminate any further development of PTX-35. As a result of the termination, the in-process R&D affiliated with PTX-35, in the amount of $3.5 million, has been fully impaired.

​

Elusys Goodwill and Intangible Assets

​

Goodwill of $3.3 million and an intangible asset of $9.7 million was recorded in connection with the acquisition of Elusys which has been allocated to the Elusys reporting unit. During the fourth quarter of 2022, due to a sustained decline in the quoted market price of its common stock, the Company performed an interim goodwill impairment analysis using the income approach. However, through its quantitative analysis, the Company determined the carrying value was not in excess of its estimated fair value and therefore no impairment charge was recorded at December 31, 2022. Elusys’ intangible asset relates to the ANTHIM® formulation and is amortized over its remaining patent life, approximately 80 months.

● University of Miami

| ● | Beginning in 2008, the Company has entered into various agreements with the University of Miami (“UM”) for intellectual and tangible property rights relating to the ImPACT®, technology activities (“License Agreement 03-31, 05-39” and “License Agreement 97-14”, or collectively “License Agreements”). These license agreements were subsequently assigned to the Company’s subsidiary Heat Biologics I, Inc. (“Heat I”) which issued to UM shares of its common stock representing 7.5% of its common stock. The term of the License Agreements is the length of the last to expire patent, unless terminated earlier.

| ● | The Company agreed to make minimum royalty payments of $10,000 for three years beginning in 2010 that are due on the anniversary date of the agreement for License Agreement 97-14. Beginning in 2013, and thereafter for the life of the agreement, the minimum royalty payment shall be $20,000 due on the same date. In July 2016, the Company and UM entered into an amendment which replaced the milestone payment of $250,000 by approval of a Biologics License Application (“BLA”) for the lung cancer vaccine with a payment of $500,000 upon approval of a New Drug Application (“NDA”) for a lung cancer vaccine covered by Patent Rights.

| ● | In August 2009, Heat I and UM entered into a second amendment (“Amendment 2”) to License Agreement UMSS-114A to extend the foregoing payment due dates for all past due license fees and patent costs.

The Company has the right to terminate this Agreement without obligation for future unpaid milestones.

| ● | In August 2009, Pelican and UM entered into a second amendment (“Amendment 2”) to License Agreement 0331, 0539 to extend the foregoing payment due dates for all past due license fees and patent costs.

| ● | In February 2010, Pelican and UM entered into a third amendment (“Amendment 3”) to License Agreement 0331, 0539 to grant back to UM a certain nonexclusive license. In all other respects, the original agreement remained the same.

| ● | In October 2010, Pelican and UM entered into a fourth amendment (“Amendment 4”) to License Agreement 0331, 0539 to grant to the licensor a nonexclusive license right for certain technology as research reagents and research tools.

License I176:

| ● | On December 12, 2010, Pelican entered into another license agreement (“I176”) with UM for one component of complimentary technology to the July 11, 2008 agreement. Pelican agreed to pay UM a license fee of $50,000 and a reimbursement of $15,797 for past patent fees. Pelican also agreed to make a minimum royalty payment of $10,000 during 2012 through 2014 and then $20,000 every year thereafter. Pelican is obligated to make milestone payments as follows: $150,000 due upon submission and approval of an IND and the completion of a Phase 1 clinical trial and $500,000 due upon the earlier of May 2024 or approval of an NDA. The Company has the right to terminate this Agreement without obligation for future unpaid milestones.

| ● | In August 2012, Pelican and UM entered into a second amendment (“I176 Amendment 2”) to License Agreement I176 to extend the foregoing payment due dates for all past due license fees and patent costs.

| ● | On December 7, 2020, the Company entered into a separate amendment to License Agreement (UMI-176) between the University of Miami and Heat Biologics, Inc. effective December 12, 2010, to extend to December 31, 2025, the date by which the University of Miami may terminate the license agreements if by such date the Company will not have introduced a licensed product into the commercial marketplace in one of the three major markets (European Union, Japan and the United States) or will not have made best efforts to achieve the same.

● Other License Agreements

| ● | On April 12, 2011, the Company entered into a non-exclusive evaluation and biological material license agreement with a not-for-profit corporation for evaluation and production of vaccines. In consideration for the licenses, the Company agreed to pay the not-for-profit corporation a fee of $5,000 and $50,000, respectively. The Company has the option to renew the license once the original term has expired. Milestone payments are due upon certain events agreed upon by Heat and the not-for-profit corporation. In December 2015, the Company amended the evaluation and biological material license agreement to add additional cell lines in exchange for a one-time payment of $1,000.

| ● | On August 30, 2010, the Company entered into an option agreement with the University of Michigan (“University”) to acquire the right to negotiate an exclusive license for certain materials which include cancer cells and all unmodified derivatives of these cells. An option fee of $2,000 was paid on September 8, 2010 to grant a period of nine months for this consideration. In July 2011, the Company exercised the option to acquire the license for $10,000.

| ● | In June 2016, the Company entered into an exclusive license agreement with Shattuck Labs, Inc. (“Shattuck”) pursuant to which the Company licensed certain provisional patent applications and know-how related to fusion proteins to treat cancer and other diseases that were not being developed by us. Shattuck paid the Company an initial license fee of $50,000 and is obligated to pay the Company fees upon its receipt of sublicensing income, achievement of certain milestones and royalties upon sales of commercial products. Inasmuch as the technology that the Company out-licensed is in the early stages of development and there is a low likelihood of success for any technology at such stage, there can be no assurance that any products will be developed by Shattuck or that the Company will derive any revenue from Shattuck.

| ● | On December 31, 2020, Zolovax, Inc. (“Zolovax”), a wholly-owned subsidiary of Heat Biologics, Inc. entered into an Exclusive License Agreement with the University of Miami for the license and development of a portfolio of patents leveraging its UMIP-510 platform to target the COVID-19 virus and other infectious diseases. The License Agreement grants Zolovax exclusive, worldwide rights to research, develop, make, use or sell Licensed Products (as defined in the License Agreement) based upon patent-related rights. The

11. Revenue

Product Sales

On April 19, 2022, Elusys entered into a contract with Public Works and Government Services of Canada to deliver 3,000 vials of ANTHIM® for treatment of inhalational anthrax due to Bacillus anthrax. The total contract award is $6.0 million with a delivery date on or before September 30, 2022. This order was fulfilled on September 13, 2022 for the total contract amount of $6.0 million.

Grant Revenue

In June 2016, Pelican entered into a cancer research grant contract (“Grant Contract”) with CPRIT, under which CPRIT awarded a grant not to exceed $15.2 million for use in developing cancer treatments by targeting a novel T-cell costimulatory receptor (namely, DR3/TNFRSF25). The Grant Contract initially covered a period from June 1, 2016 through November 30, 2019, as amended, was extended to May 30, 2022. The first tranche of funding of $1.8 million was received in May 2017, a second tranche of funding of $6.5 million was received in October 2017, and a third tranche of funding of $5.4 million was received in December 2019. The remaining $1.5 million will be awarded on a reimbursement basis after we have fulfilled every requirement of the grant and the grant has been approved to be finalized. As of December 31, 2022, all $15.2 million has been recognized.

The grant is subject to customary CPRIT funding conditions including a matching funds requirement where Pelican will match $0.50 for every $1.00 from CPRIT. Consequently, Pelican is required to provide $7.6 million in matching funds over the life of the project. Upon commercialization of the product, the terms of the grant require Pelican to pay tiered royalties in the low to mid-single digit percentages. Such royalties reduce to less than one percent after a mid-single-digit multiple of the grant funds have been paid to CPRIT in royalties.

As of December 31, 2022, we had a grant receivable balance of $1.5 million for CPRIT proceeds not yet received but for which the costs had been incurred or the conditions of the award had been met. At the conclusion of the grant the Company will be subject to an audit by CPRIT before the final grant payment can be approved and distributed. The Company believes this will not be finalized until the end of 2023.

​

​ |  | 2022 |  | 2021

​ | ​ | $ | 4,085,737 | ​ | $ | 6,168,981

​

Accounting for Stock-Based Compensation:

Stock Compensation Expense - For the years ended December 31, 2022, and 2021, we recorded $4,085,737, and $6,168,981 of stock-based compensation expense, respectively. No compensation expense of employees with stock awards was capitalized during the years ended December 31, 2022 and 2021.

Stock Options - Under the Plans, we have issued stock options. A stock option granted gives the holder the right, but not the obligation to purchase a certain number of shares at a predetermined price for a specific period of time. We typically issue options that vest over four years in equal installments beginning on the first anniversary of the date of grant. Under the terms of the Plans, the contractual life of the option grants may not exceed ten years. During the years ended December 31, 2022, and 2021, we issued options that expire ten years from the date of grant.

Fair Value Determination - We have used the Black-Scholes-Merton option pricing model to determine fair value of our stock option awards on the date of grant.

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)

The following weighted-average assumptions were used for option grants during the years ended December 31, 2022 and 2021:

​

| ● | Volatility – The Company used an average historical stock price volatility of its own data plus an analysis of reported data for a peer group of comparable companies that have issued stock options with substantially similar terms.

​

| ● | Expected life of options – The expected term represents the period that the Company’s stock option grants are expected to be outstanding. The Company elected to utilize the “simplified” method to estimate the expected term as the company does not have sufficient appropriate exercise data on which to base its estimate. Under this approach, the weighted-average expected life is presumed to be the average of the vesting term and the contractual term of the option.

​

| ● | Risk-free interest rate – The rate is based on U.S. Treasury interest rates at the time of the grant whose term is consistent with the expected life of the stock options.

​

| ● | Dividend yield – The expected dividend yield was considered to be 0% in the option pricing formula since the Company had not paid any dividends and had no plan to do so in the future.

​

| ● | Forfeitures – The Company’s policy is to account for forfeitures as they occur. ​

The following table summarizes assumptions used in our calculations of fair value for the years ended December 31, 2022 and 2021:

​

​ | ​ | ​ | ​ | ​ | ​ | ​
​ |  | 2022 | ​ | ​ | 2021 | ​
Dividend yield |  | — | % | ​ | — | %
Expected volatility |  | 100.85-105.09 | % | ​ | 99.34-104.61 | %
Risk-free interest rate |  | 1.95-3.61 | % | ​ | 0.36-1.36 | %
Expected lives (years) |  | 5.3-6.1 | years | ​ | 5.0-6.1 | years

​

Stock Option Activity - The weighted-average grant date fair value of options granted during the years ended December 31, 2022 and 2021 was $0.87 and $3.67, respectively.

Unrecognized compensation expense related to unvested stock options was $5.4 million as of December 31, 2022, which is expected to be recognized over a weighted-average period of 1.30 years and will be adjusted for forfeitures as they occur.

​

Restricted Stock - Under the Plans, the Company has issued restricted stock. A restricted stock award is an issuance of shares that cannot be sold or transferred by the recipient until the vesting period lapses. Restricted stock issued to members of our Board of Directors and Executives vest 50% on the grant date, 30% on the first anniversary and 10% each anniversary thereafter. The grant date fair value of the restricted stock is equal to the closing market price of the Company’s common stock on the date of grant.

​

The aggregate fair value of awards that vested during the years ended December 31, 2022 and 2021 was $1.6 million and $2.2 million.

​

RSUs - Under the Plans, the Company has time-based RSUs. RSUs are not actual shares, but rather a right to receive shares in the future. The shares are not issued and the employee cannot sell or transfer shares prior to vesting and has no voting rights until the RSUs vest. The employees' time-based RSUs will result in the delivery of shares in one-fourth increments commencing on the award date. The grant date fair value of the RSUs is equal to the closing market price of the Company’s common stock on the grant date. The Company recognizes the grant date fair value of RSUs of shares it expects to issue as compensation expense ratably over the requisite service period.

​

At December 31, 2022 and December 31, 2021, the Company evaluated all significant available positive and negative evidence, including the existence of losses in recent years and management’s forecast of future taxable income, and, as a result, determined it was more likely than not that federal and state deferred tax assets, including benefits related to net operating loss carryforwards, would not be realized. The company completed a 382 analysis to determine any limitations on the annual usage of their NOL carryforwards (discussed in further detail below). The allowance increased to $30,939,958 at December 31, 2022. Net Operating Losses created in years beginning after 2017 now only offset 80% of Taxable Income but no longer have a 20 year expiration. As such, NOL’s created after 2017 can be used to offset indefinite lived liabilities up to 80%.

​

At December 31, 2022, the Company has federal net operating loss carryforwards of approximately $174,285,827, including $3,027,284 acquired from Pelican Therapeutics. However, due to Section 382 limitations (discussed in further detail below), only $116,493,744 of the NOLs are available to offset future taxable income. The federal net operating loss carryforwards begin to expire in 2029. The Company has various state net operating loss carryforwards totaling approximately $124,461,888 including $2,464,819 from Pelican Therapeutics, which are available to offset future state taxable income. State net operating losses begin to expire in 2024. On November 15, 2021, the North Carolina General Assembly passed Senate Bill 105 eliminating the current 2.5% corporate income tax by phased lowering of the rate from 2025 – 2030. A reserve has been set up for North Carolina NOLs that are not expected to be used by 2030. The Company has various foreign net operating loss carryforwards of $125,097. The foreign net operating loss carryforwards are carried forward indefinitely. Because the Company has incurred cumulative net operating losses since inception, all tax years remain open to examination by U.S. federal, state, and foreign income tax authorities.

​

In accordance with FASB ASC 740, Accounting for Income Taxes, the Company reflects in the financial statements the benefit of positions taken in a previously filed tax return or expected to be taken in a future tax return only when it is considered ‘more-likely-than-not’ that the position taken will be sustained by a taxing authority. As of December 31, 2022, and 2021, the Company had no unrecognized income tax benefits and correspondingly there is no impact on the Company’s

effective income tax rate associated with these items. The Company’s policy for recording interest and penalties relating to uncertain income tax positions is to record them as a component of income tax expense in the accompanying statements of income. As of December 31, 2022 and 2021, the Company had no such accruals

​

The Company files income tax returns in the United States, various state and foreign jurisdictions. The Company was subject to examination by taxing authorities for the tax years ended December 31, 2009 through 2021.

Potential 382 Limitation

The Company’s ability to utilize its NOL and research and development (R&D) credit carryforwards may be substantially limited due to ownership changes that have occurred or that could occur in the future, as required by Section 382 of the Internal Revenue Code of 1986, as amended (the Code), as well as similar state provisions. These ownership changes may limit the amount of NOL and R&D credit carryforwards that can be utilized annually to offset future taxable income and tax, respectively. In general, an “ownership change,” as defined by Section 382 of the Code, results from a transaction or series of transactions over a three-year period resulting in an ownership change of more than 50 percent of the outstanding stock of a company by certain stockholders or public groups.

​

The Company completed a Section 382 study during 2021. It was determined that the Company has experienced five ownership changes of over 50% since 2013, the latest occurring on June 30, 2020. Going forward, the utilization of loss carryforwards and tax credits generated before June 30, 2020 will be subject to an annual limitation. As a result of the ownership changes and limitations, $58,181,799 of federal NOLs and approximately $2,935,000 of federal R&D credits will expire unutilized, in addition to Section 382 limits on Pelican already in place.

​

14. Leases

​

The Company accounts for its leases under ASC 842, “Leases”. The Company has determined that its leases for office and laboratory space without optional terms or variable components are operating leases.

​

The Company conducts its operations from leased facilities in Morrisville, North Carolina; San Antonio, Texas; Parsippany, New Jersey and North Brunswick, New Jersey. The North Carolina lease will expire in 2030, the Texas lease will expire in 2037, the Parsippany and New Brunswick leases will expire in July 2023. The leases are for general office space, manufacturing space, and lab space and require the Company to pay property taxes, insurance, common area expenses and maintenance costs.

​

In June 2021, the Company entered into a lease agreement with Durham KTP Tech 7, LLC, to lease a 15,996 square foot facility in Morrisville, North Carolina to expand its research and development activities. The lease has a term of eight years following the commencement date and provides the Company the option to extend the lease term for one five year term, however option to extend was not included in the ROU asset and liability. It is subject to fixed rate escalation increases and also provides up to $2.4 million for tenant improvements. NightHawk recorded an operating lease right-of-use asset of $5.6 million and lease liability of $3.2 million for this lease in the accompanying consolidated balance sheets.

​

In October 2021, Scorpius entered into a lease agreement with Merchants Ice II, LLC to lease a 20,144 square foot facility in San Antonio, TX for general office, laboratory, research, analytical, and/or biomanufacturing purposes. Merchants Ice II, LLC is a nonprofit entity investing in the building with the intention to encourage development of emerging technologies. As a result, investments made by both Merchants Ice II, LLC and Scorpius into the building may qualify and share tax credits under the New Market Tax Credit (“NMTC”) program. Scorpius agreed that all investments and expenditures qualifying under the NMTC (i.e., certain equipment and building improvements) would be purchased by Merchants Ice II, LLC to generate the largest possible tax incentive and Scorpius would reimburse Merchants Ice II, LLC for these payments. The lease officially commenced on September 15, 2022. As of December 31, 2022, Scorpius has reimbursed Merchants Ice II, LLC $24.3 million. Based on ASC 842, the Company has capitalized $13.2 million of the reimbursements as lab equipment, expensed $0.9 million as supplies and facilities, and $10.2 million has been included in the finance lease right-of-use asset. The lease has a term of fifteen years following the commencement date and provides

Scorpius the option to extend the lease term for one fifteen-year term, and one subsequent ten year term upon expiration of the first extended term. These options to extend were not included in the ROU asset and lease liability. It is subject to fixed rate escalation increases and also provides up to $2.4 million for tenant improvements. Scorpius recorded a finance lease right-of-use asset of $15.1 million and lease liability of $5.1 million for this lease in the accompanying consolidated balance sheets.

​

Total cash paid for operating leases during the years ended December 31, 2022 and 2021 was $0.8 million and $0.4 million and is included within cash flows from operating activities within the consolidated statements of cash flows.

​

The Company leases furniture and specialized lab equipment under finance leases. The related right-of-use assets are amortized on a straight-line basis over the lesser of the lease term or the estimated useful life of the asset. The effective interest rate was 5.80% and 5.30% for the years ended December 31, 2022 and 2021.

​

The Company’s lease cost reflected in the accompanying statements of operations and comprehensive loss is as follows:

15. Related Party Transactions

Prior to acquisition, Jeffrey Wolf, President, Chief Executive Officer and Chairman of the Board of Directors, was a director of Elusys and directly and through affiliated entities owned approximately 1.2% of the outstanding stock of Elusys, in the form of common stock, which is subordinate in terms of distributions to the Elusys preferred stock. Common stockholders are not expected to receive any future payments as presently it seems most, if not all, of such payments will also be paid to the preferred stockholders of Elusys.

​

16. Net Loss Per Share

Basic net loss per common share is computed by dividing net loss attributable to common stockholders by the weighted-average number of common shares outstanding during the periods. Fully diluted net loss per common share is computed using the weighted average number of common and dilutive common equivalent shares outstanding during the periods. Common equivalent shares consist of stock options, restricted stock units, and warrants that are computed using the treasury stock method.

For the years ended December 31, 2022 and 2021, all of the Company’s common stock options, unvested restricted stock units and warrants are anti-dilutive and therefore have been excluded from the diluted net loss per common share calculation.

The following table reconciles net loss to net loss attributable to NightHawk Biosciences, Inc.:
