The Plaintiff amended the complaint in February 2020 to include Vipin K. Garg and David J. Drutz as defendants, in addition to the Company (Dr. Garg, Dr. Drutz, and the Company are collectively referred to as &#8220;Defendants&#8221;). In March 2020 the Defendants filed a motion to dismiss the complaint. The Court denied the motion without prejudice and allowed Plaintiff an opportunity to file an amended complaint. Plaintiff&#8217;s second amended complaint was filed on April 17, 2020, and Defendants filed a motion to dismiss that complaint on May 1, 2020. A hearing on Defendants&#8217; motion to dismiss was held on May 20, 2020. Plaintiff, who is representing himself, alleges five causes of action as follows: (1) Defendants&#8217; alleged retention of Plaintiff&#8217;s lab notebooks after the termination of his employment in 2012; (2) alleged plagiarism based on publishing an article without naming Plaintiff as an author; (3) use of the Adhigh System, which Plaintiff alleges he developed; (4) allegations that Defendants manipulated our stock and caused a decrease in value; and (5) allegations that the Defendants &#8220;wast[ed] government grant money and poison[ed] science by leaving data to rot.&#8221; On September 30, 2020, Plaintiff filed a motion titled &#8220;Motion to Proscribe Defendants&#8217; Allegedly Illegal Use of Plaintiff&#8217;s AdHigh System in Altimmune&#8217;s Human Clinical Trials,&#8221; to which Defendants filed an opposition on October 13, 2020. The court has not yet ruled on that motion, which also remains pending. On November 6, 2020, Defendants filed a motion for summary judgment on the basis of lack of personal jurisdiction, insufficient service of process, and failure to state a claim. The court ruled on that motion on March 25, 2021, which dismissed the case on the basis of lack of personal jurisdiction. On December 1, 2020, the magistrate judge assigned to the case issued a report and recommendation that Defendants&#8217; motion to dismiss of May 1, 2020 be granted and that this action be dismissed for lack of personal jurisdiction. Plaintiff filed objections to the report and recommendation on December 14, 2020, and the resolution of those objections by the district court remains pending. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In December 2021, the Plaintiff refiled the complaint in the United States District Court for the District of Maryland. On February 24, 2022, Defendants filed a memorandum containing a brief description of the planned motion and a concise summary of the factual and legal support for it. On the basis of that memorandum, the Court granted Defendants&#8217; request to file a motion to dismiss and allowed Plaintiff an opportunity to file an amended complaint. &#160;Plaintiff&#8217;s amended complaint was filed on March 3, 2022, and Defendants filed a motion to dismiss that complaint on April 4, 2022.

We have reopened our executive office to allow employees to return to the office based on an approach that is intended to comply with federal and state guidelines, with a focus on employee safety and optimal work environment. We are continuing our regular interactions with the FDA and other regulatory agencies and, based on current information, we do not anticipate COVID-19 to materially affect our regulatory timelines for our ongoing clinical trials. Furthermore, as a government contractor, we are subject to the federal government vaccination mandate, which requires federal contractor employees, except in certain limited circumstances, to be vaccinated against COVID-19 by December 8, 2021. While the vaccination mandate remains subject to the interpretation of various government agencies and other entities, and questions remain regarding the specific application of the vaccination mandate, we are continuing to develop and implement health, safety, employment and operational protocols in order to timely comply with the vaccination mandate. As of and for the three months ended March 31, 2022, the vaccination mandate has not had a material impact on our employees or operations. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">Although operations have not been materially affected by the COVID-19 pandemic as of and for the three months ended March&#160;31,&#160;2022, at this time, however, there is uncertainty relating to the trajectory of the pandemic and the impact </p></div><div style="clear:both;margin-bottom:30pt;width:100%;"><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:center;margin:24pt 0pt 0pt 0pt;">16</p></div></div>

The impact of COVID-19 on our future results will largely depend on future developments, which are highly uncertain and cannot be predicted with confidence, such as the ultimate geographic spread of the disease, the duration of the pandemic, travel restrictions and social distancing in the United States and other countries, business closures or business disruptions, the ultimate impact on financial markets and the global economy, and the effectiveness of actions taken in the United States and other countries to contain and treat the disease. In addition, a recurrence of COVID-19 cases, or variants thereof, could cause other widespread or more severe impacts depending on where infection rates are highest. We continue to monitor developments as we deal with the disruptions and uncertainties relating to the COVID-19 pandemic.

As the conflict continues to evolve, we are closely monitoring the impact on our business. The conflict, and the sanctions and counter-sanctions imposed in response to it, have created increased economic uncertainty and operational complexity globally. While we have no direct exposure to Russia and Ukraine, and do not at the moment believe the situation will have a material impact on our operating results, we are monitoring any broader economic impact from the situation. Should the conflict continue or escalate, it could have a significant negative effect on the global economy or on our operations, including continued inflationary pressures on raw materials, supply chain and logistics disruptions, volatility in foreign exchange rates and interest rates and heightened cybersecurity threats. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"><span style="visibility:hidden;">&#8203;</span></p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-weight:bold;margin:0pt 0pt 12pt 0pt;">U.S. Government Contracts and Grants</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In June&#160;2020, we were awarded $4.7 million from the U.S. Army Medical Research&#160;&amp; Development Command (&#8220;USAMRDC&#8221;) to fund our Phase 1/2 clinical trial of T-COVID. The competitive award was granted by USAMRDC in collaboration with the Medical Technology Enterprise Consortium (&#8220;MTEC&#8221;), a 501(c)(3)&#160;biomedical technology consortium working in partnership with the Department of Defense (&#8220;DoD&#8221;). Under the contract, MTEC paid us a firm fixed fee based upon the achievement of certain milestones for conduct and completion of a Phase 1/2 study and research and development work on the replication-deficient adenovirus 5 (&#8220;RD-Ad5&#8221;) vector vaccine platform. For the three months ended March 31, 2021, we recognized approximately $0.5 million of grant revenue under the contract, which completed the full recognition of this award. No revenue was recognized for this contract for the three months ended March 31, 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In July&#160;2016, we signed a five-year contract with Biomedical Advanced Research and Development Authority (&#8220;BARDA&#8221;). The contract, as amended, had a total value of up to $136.8 million to be used to fund clinical development of NasoShield. Under the contract, BARDA paid us a fixed fee and reimbursed certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consisted of an initial base performance period providing approximately $30.9 million in funding for the period July&#160;2016 through December&#160;2021. BARDA had seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical trials. Each option, if exercised by BARDA, would have provided additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning in&#160;2021. For the three months ended March 31, 2021, we recognized approximately $0.2 million of grant revenue under the BARDA contract. For the three months ended March 31, 2022, we have recognized de minimis grant revenue related to the close-out of the BARDA contract.

Our sources of revenue have consisted of grant revenues under our arrangements with BARDA for the development of NasoShield, MTEC for a clinical trial and development work on T-COVID, and to a lesser degree from other licensing arrangements. We have incurred significant losses since we commenced operations. As of March&#160;31,&#160;2022, we had an accumulated deficit of $312.6 million. In addition, we have not generated positive cash flows from operations. We have had to rely on a variety of financing sources, including the issuance of debt and equity securities. As capital resources are consumed to fund our research and development activities, we may require additional capital beyond our currently anticipated amounts. In order to address our capital needs, including our planned clinical trials, we must continue to actively pursue additional equity or debt financing, government funding, and monetization of our existing programs through partnership arrangements or sales to third parties.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In June&#160;2020, we were awarded $4.7 million from the U.S. Army Medical Research&#160;&amp; Development Command (&#8220;USAMRDC&#8221;) to fund our Phase 1/2 clinical trial of T-COVID.

The contract, as amended, had a total value of up to $136.8 million to be used to fund clinical development of NasoShield. Under the contract, BARDA paid us a fixed fee and reimbursed certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consisted of an initial base performance period providing approximately $30.9 million in funding for the period July&#160;2016 through December&#160;2021. BARDA had seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical trials. Each option, if exercised by BARDA, would have provided additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning in&#160;2021. Through March 31, 2022, we have collected approximately $29.5 million in cash under the BARDA contract.

The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of our common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of our common stock then issued and outstanding, which&#160;percentage may change at the holders&#8217; election to any other number less than or equal to 19.99% upon 61&#160;days&#8217; notice to us. The gross proceeds of this offering were approximately $132.2 million, which includes the exercise in full of the underwriters&#8217; option to purchase an additional 750,000 shares of common stock, before deducting underwriting discounts and commissions and offering expenses during the third quarter of 2020. The net proceeds of this offering were approximately $124.0 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company. As of March 31, 2022, 760,870 of the Pre-Funded Warrants were exercised, leaving 869,566 remaining Pre-Funded Warrants unexercised.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">At-the-Market Offerings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On February&#160;25, 2021, we entered into an Equity Distribution Agreement (the &#8220;2021 Agreement&#8221;) with Piper Sandler&#160;&amp; Co., Evercore Group L.L.C. and B.

The results of any current or future litigation cannot be predicted with certainty, and 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.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In December 2019, a complaint was filed by Dr. De-Chu Christopher Tang (&#8220;Plaintiff&#8221;) against us, which we removed to the United States District Court for the Eastern District of Texas.

The financial statements do not include any adjustments relating to the recoverability and classification of recorded assets and liabilities that might be necessary should we be unable to continue as a going concern.</p><span></span>

Contingent Consideration</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Company entered into an Agreement and Plan of Merger and Reorganization, dated July&#160;8, 2019, by and among the Company, Springfield Merger Sub,&#160;Inc., Springfield Merger Sub, LLC, Spitfire Pharma,&#160;Inc. and David Collier, as the Stockholder Representative (the &#8220;Spitfire Merger Agreement&#8221;) to acquire all of the equity interests of Spitfire Pharma,&#160;Inc. (&#8220;Spitfire&#8221;). Spitfire was a privately held, preclinical pharmaceutical company developing a novel dual GLP-1/glucagon receptor agonist for the treatment of non-alcoholic steatohepatitis.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The transaction closed on July&#160;12, 2019. The Company issued 1,887,250 unregistered shares of its common stock as upfront consideration to certain former securityholders of Spitfire (collectively, the &#8220;Spitfire Equityholders&#8221;), representing an amount equal to $5.0 million less working capital and transaction expense adjustment amounts as defined in the agreement.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The acquisition of Spitfire was accounted for as an asset acquisition instead of a business combination because substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset or group of similar identifiable assets, and therefore, the asset was not considered a business. The Company expensed the acquired intellectual property as of the acquisition date as in-process research and development with no alternative future uses.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Spitfire Merger Agreement also includes future contingent payments up to $88.0 million in cash and shares of the Company&#8217;s common stock as follows (each, a &#8220;Milestone Event&#8221;):</p><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:18pt;"/><td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">&#9679;</td><td style="padding:0pt;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">a one-time payment of </span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">$5.0</span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"> million (the &#8220;IND Milestone Consideration Amount&#8221;) within </span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">sixty days</span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"> of the submission of an Investigational New Drug Application (&#8220;IND&#8221;) to the United States Food and Drug Administration (the &#8220;FDA&#8221;) or other applicable governmental authority in a foreign jurisdiction, which IND has not been rejected or placed on clinical hold by the FDA or such applicable foreign governmental authority within time specified in the Merger Agreement;</span></td></tr></table><table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"><tr><td style="width:18pt;"/><td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;">&#9679;</td><td style="padding:0pt;"><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">a one-time payment of </span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;">$3.0</span><span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"> million (the &#8220;Phase 2 Milestone Consideration Amount&#8221;

Such stock-based payments are subject to a lock-up whereby 50% of the shares are released at 3&#160;months and 50% are released at 6&#160;months. The future contingent payments related to the Sales Milestones are predominately cash-based payments accounted for under FASB Accounting Standards Codification Topic 450, <i style="font-style:italic;">Contingencies</i>. Accordingly, the Company will recognize the Sales Milestones when the contingency is probable and the amount is reasonably estimated.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On November&#160;3, 2020, the Company received acknowledgement from the Australian Government Department of Health on the Company&#8217;s submitted clinical trial notification (&#8220;CTN&#8221;) which triggered the obligation to settle the IND Milestone payment to the former owners. As a result, on November&#160;19, 2020, the Company issued 1,694,906 shares of its Common Stock valued at $9.57 per share for the amount value of $13.6 million to the former Spitfire stockholders. Pursuant to the Spitfire Merger Agreement, the Company issued the shares within sixty days of the submission of the CTN, which was October&#160;29, 2020. From September&#160;30, 2020 through November 19, 2020, the date of issuance, the Company recognized a decrease in the fair value of the IND Milestone payment of $5.4 million to research and development expense and reclassified the balance in the contingent consideration liability associated with the fair value of the IND Milestone payment to equity in the Company&#8217;s consolidated balance sheet. No Regulatory Milestones were achieved during the three months ended March 31, 2022. The Phase 2 Milestone was met on April 26, 2022. See Note 17 for further details.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">The Company estimates the future contingent consideration for the Regulatory Milestones based upon a Monte Carlo simulation valuation model that is risk adjusted based on the probability of achieving the milestones and a discount for lack of marketability. The Company remeasures the fair value of the contingent consideration at each reporting period. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;">During the fourth quarter of 2020, the Company achieved the IND Milestone and paid the obligation in shares according to the calculation above.

The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of the Company&#8217;s common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company&#8217;s common stock then issued and outstanding, which&#160;percentage may change at the holders&#8217; election to any other number less than or equal to 19.99% upon 61 days&#8217; notice to the Company. The gross proceeds of this offering were approximately $132.2 million, which includes the exercise in full of the underwriters&#8217; option to purchase an additional 750,000 shares of common stock, before deducting underwriting discounts and commissions and offering expenses during the third quarter of 2020. The net proceeds of this offering were approximately $124.0 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Company has assessed the Pre-Funded Warrants for appropriate equity or liability classification and determined that the Pre-Funded Warrants are freestanding instruments that do not meet the definition of a liability pursuant to ASC 480 and do not meet the definition of a derivative pursuant to FASB Accounting Standards Codification Topic 815, <i style="font-style:italic;">Derivatives and Hedging</i> (&#8220;ASC 815&#8221;). The Pre-Funded Warrants are indexed to the Company&#8217;s common stock and meet all other conditions for equity classification under ASC 480 and ASC 815. Accordingly, the Pre-Funded Warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. As of March&#160;31,&#160;2022, 760,870 of the Pre-Funded Warrants were exercised, leaving 869,566 remaining Pre-Funded Warrants unexercised.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">At-the-Market Offerings</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On February&#160;25, 2021, the Company entered into an Equity Distribution Agreement (the &#8220;2021 Agreement&#8221;) with Piper Sandler&#160;&amp; Co., Evercore Group L.L.C. and B. Riley Securities,&#160;Inc., serving as sales agents (the &#8220;Sales Agents&#8221;) with respect to an at-the-market offerings program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.0001 per share (the &#8220;Common Stock&#8221;), having an aggregate offering price of up to $125.0 million (the &#8220;Shares&#8221;) through the Sale Agents (the &#8220;2021 Offering&#8221;). Any Shares offered and sold in the 2021 Offering will be issued pursuant to the Company&#8217;s Registration Statement on Form&#160;S-3 filed with the Securities and Exchange Commission (the &#8220;SEC&#8221;) on December&#160;31, 2020, which was declared effective on January&#160;11, 2021, the prospectus supplement relating to the 2021 Offering filed with the SEC on February&#160;25, 2021 and any applicable additional prospectus supplements related to the 2021 Offering that form a part of the Registration Statement.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">During the three months ended March 31, 2022, the Company sold 335,485 shares of Common Stock under the 2021 Agreement resulting in approximately $3.0 million in net proceeds. As of March&#160;31,&#160;2022, the Company has sold in aggregate 5,135,939 shares of Common Stock under the 2021 Agreement resulting in approximately $67.8 million in net proceeds, with $55.0 million remaining available to be sold under the 2021 Agreement. As of March&#160;31,&#160;2022, the Company recorded approximately $0.1 million of offering costs which offset the proceeds received from the shares sold through March&#160;31,&#160;2022. The Company capitalized approximately $0.1 million of deferred offering costs which will offset future proceeds received under the 2021 Agreement.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;">Exchange Agreement</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">On February&#160;25, 2021, the Company entered into an exchange agreement (the &#8220;Exchange Agreement&#8221;) with an Investor and its affiliates (the &#8220;Exchanging Stockholders&#8221;), pursuant to which the Company exchanged an aggregate of 1,000,000 shares of the Company&#8217;s common stock, par value $0.0001 per share, owned by the Exchanging Stockholders for pre-funded warrants (the &#8220;Exchange Warrants&#8221;) to purchase an aggregate of 1,000,000 shares of common stock (subject to adjustment in the event of any stock dividends and splits, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Exchange Warrants), with an exercise price of $0.0001 per share. The Exchange Warrants did not have an expiration date and were exercisable at any time except that the Exchange Warrants could not be exercised by the Exchanging Stockholders if, after giving effect thereto, the Exchanging Stockholders would beneficially own more than 9.99% of the Company&#8217;s common stock, subject to certain exceptions. In accordance with FASB Accounting Standards Codification Topic 505, <i style="font-style:italic;">Equity</i>, the Company recorded the retirement of the common stock exchanged as a reduction of common shares outstanding and a corresponding debit to additional paid-in-capital and accumulated deficit at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants were classified as equity in accordance with ASC 480 and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of March&#160;31,&#160;2022, the Exchange Warrants to purchase 1,000,000 shares were net exercised, resulting in the issuance of 999,984 shares of common stock. All of the Exchange Warrants were exercised in full.</p><span></span>

U.S. Government Contracts and Grants</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In June&#160;2020, the Company was awarded $4.7 million from the U.S. Army Medical Research&#160;&amp; Development Command (&#8220;USAMRDC&#8221;) to fund its Phase 1/2 clinical trial of T-COVID. The competitive award was granted by USAMRDC in collaboration with the Medical Technology Enterprise Consortium (&#8220;MTEC&#8221;), a 501(c)(3)&#160;biomedical technology consortium working in partnership with the Department of Defense (&#8220;DoD&#8221;). Under the contract, MTEC paid the Company a firm fixed fee based upon the achievement of certain milestones for conduct and completion of a Phase </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt 0pt 12pt 0pt;">1/2 study and research and development work on the replication-deficient adenovirus 5 (&#8220;RD-Ad5&#8221;) vector vaccine platform. For the three months ended March&#160;31,&#160;2021, the Company recognized approximately $0.5 million of grant revenue under the contract, which completed the full recognition of this award. No revenue was recognized for this contract for the three months ended March 31, 2022.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;">In July&#160;2016, the Company signed a five-year contract with Biomedical Advanced Research and Development Authority (&#8220;BARDA&#8221;). The contract, as amended, had a total value of up to $136.8 million to be used to fund clinical development of NasoShield. Under the contract, BARDA paid the Company a fixed fee and reimbursed certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consisted of an initial base performance period providing approximately $30.9 million in funding for the period July&#160;2016 through December&#160;2021. BARDA had seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical studies. Each option, if exercised by BARDA, would have provided additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning in 2021. For the three months ended March 31, 2021, the Company recognized approximately $0.2 million of grant revenue under the BARDA contract. For the three months ended March&#160;31,&#160;2022, the Company has recognized de minimis grant revenue related to the close-out of the BARDA contract. BARDA did not extend the contract beyond the end of December 2021.</p><span></span>

Net Loss Per Share</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Because the Company has reported a net loss attributable to common stockholders for all periods presented, basic and diluted net loss per share attributable to common stockholders are the same for all periods presented.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Basic net loss per share attributable to common stockholders is computed by dividing the net loss attributable to common stockholders by the weighted average numbers of shares of common stock outstanding for the period. Basic shares outstanding includes the weighted average effect of the Company&#8217;s outstanding pre-funded warrants, the exercise of which requires little or no consideration for the delivery of shares of common stock.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">Diluted net loss per share is calculated by adjusting weighted average shares outstanding for the dilutive effect of common stock equivalents outstanding for the period. As such, all unvested restricted stock, restricted stock units, common stock warrants, and stock options have been excluded from the computation of diluted weighted average shares outstanding because such securities would have an anti-dilutive impact for all periods presented.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 6pt 0pt;">Potential common shares issuable upon conversion, vesting or exercise of unvested restricted stock, restricted stock units, common stock warrants, and stock options that are excluded from the computation of diluted weighted-average shares outstanding, as they are anti-dilutive, are as follows:</p><table

The Plaintiff amended the complaint in February 2020 to include Vipin K. Garg and David J. Drutz as defendants, in addition to the Company (Dr. Garg, Dr. Drutz, and the Company are collectively referred to as &#8220;Defendants&#8221;). In March 2020 the Defendants filed a motion to dismiss the complaint. The Court denied the motion without prejudice and allowed Plaintiff an opportunity to file an amended complaint. Plaintiff&#8217;s second amended complaint was filed on April 17, 2020, and Defendants filed a motion to dismiss that complaint on May 1, 2020. A hearing on Defendants&#8217; motion to dismiss was held on May 20, 2020. Plaintiff, who is representing himself, alleges five causes of action as follows: (1) Defendants&#8217; alleged retention of Plaintiff&#8217;s lab notebooks after the termination of his employment in 2012; (2) alleged plagiarism based on publishing an article without naming Plaintiff as an author; (3) use of the Adhigh System, which Plaintiff alleges he developed; (4) allegations that Defendants manipulated our stock and caused a decrease in value; and (5) allegations that the Defendants &#8220;wast[ed] government grant money and poison[ed] science by leaving data to rot.&#8221; On September 30, 2020, Plaintiff filed a motion titled &#8220;Motion to Proscribe Defendants&#8217; Allegedly Illegal Use of Plaintiff&#8217;s AdHigh System in Altimmune&#8217;s Human Clinical Trials,&#8221; to which Defendants filed an opposition on October 13, 2020. The court has not yet ruled on that motion, which also remains pending. On November 6, 2020, Defendants filed a motion for summary judgment on the basis of lack of personal jurisdiction, insufficient service of process, and failure to state a claim. The court ruled on that motion on March 25, 2021, which dismissed the case on the basis of lack of personal jurisdiction. On December 1, 2020, the magistrate judge assigned to the case issued a report and recommendation that Defendants&#8217; motion to dismiss of May 1, 2020 be granted and that this action be dismissed for lack of personal jurisdiction. Plaintiff filed objections to the report and recommendation on December 14, 2020, and the resolution of those objections by the district court remains pending. </p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">In December 2021, the Plaintiff refiled the complaint in the United States District Court for the District of Maryland. On February 24, 2022, Defendants filed a memorandum containing a brief description of the planned motion and a concise summary of the factual and legal support for it. On the basis of that memorandum, the Court granted Defendants&#8217; request to file a motion to dismiss and allowed Plaintiff an opportunity to file an amended complaint. &#160;Plaintiff&#8217;s amended complaint was filed on March 3, 2022, and Defendants filed a motion to dismiss that complaint on April 4, 2022. The Company believes the allegations in the complaint are without merit and intends to vigorously defend the litigation.</p><p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;">The Company is a party in various contracts and subject to disputes, litigation, and potential claims arising in the ordinary course of business, none of which are currently reasonably possible or probable of material loss.</p><span></span>

Warrants and rights outstanding are derivative securities that give the holder the right to purchase securities (usually equity) from the issuer at a specific price within a certain time frame. Warrants are often included in a new debt issue to entice investors by a higher return potential. The main difference between warrants and call options is that warrants are issued and guaranteed by the company, whereas options are exchange instruments and are not issued by the company. Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months. Disclose the title of issue of securities called for by warrants and rights outstanding, the aggregate amount of securities called for by warrants and rights outstanding, the date from which the warrants or rights are exercisable, and the price at which the warrant or right is exercisable.</p></div>

(&#x201c;Lonza&#x201d;) for the manufacture of AdCOVID or other adenovirus-based vaccines. Under the expanded agreement, the Company had committed approximately $23.0 million to Lonza to procure long-lead equipment and construct a dedicated manufacturing suite for clinical and commercial production of adenovirus-based vaccines. This work was completed during the fourth quarter of 2021. The Company capitalized a total of $4.0 million as construction-in-progress (&#x201c;CIP&#x201d;) during the three months ended March 31, 2021 under this expanded agreement.

Spitfire was a privately held, preclinical pharmaceutical company developing a novel dual GLP-1/glucagon receptor agonist for the treatment of non-alcoholic steatohepatitis.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;The transaction closed on July&#160;12, 2019. The Company issued 1,887,250 unregistered shares of its common stock as upfront consideration to certain former securityholders of Spitfire (collectively, the &#x201c;Spitfire Equityholders&#x201d;), representing an amount equal to $5.0 million less working capital and transaction expense adjustment amounts as defined in the agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;The acquisition of Spitfire was accounted for as an asset acquisition instead of a business combination because substantially all of the fair value of the gross assets acquired was concentrated in a single identifiable asset or group of similar identifiable assets, and therefore, the asset was not considered a business. The Company expensed the acquired intellectual property as of the acquisition date as in-process research and development with no alternative future uses.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;The Spitfire Merger Agreement also includes future contingent payments up to $88.0 million in cash and shares of the Company&#x2019;s common stock as follows (each, a &#x201c;Milestone Event&#x201d;):&lt;/p&gt;&lt;table style="border-collapse:collapse;font-family:'Times New Roman','Times','serif';font-size:10pt;margin-bottom:12pt;margin-top:0pt;table-layout:fixed;text-align:justify;width:100%;border:0pt;"&gt;&lt;tr&gt;&lt;td style="width:18pt;"/&gt;&lt;td style="font-family:'Times New Roman','Times','serif';font-size:10pt;vertical-align:text-top;white-space:nowrap;width:18pt;padding:0pt;"&gt;&#x25cf;&lt;/td&gt;&lt;td style="padding:0pt;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;a one-time payment of &lt;/span&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;$5.0&lt;/span&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;

The number of any shares issued in consideration for the IND Milestone Consideration Amount will be determined based on lower of (A)&#160;the average of the closing prices of our Common Stock as reported on the Nasdaq Global Market for the &lt;span style="-sec-ix-hidden:Hidden_fG-CRYmtvUeeH-VUmJgOog;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;twenty&lt;/span&gt;&lt;/span&gt; (20) consecutive trading&#160;days prior to the IND Reference Date or (B)&#160;$2.95. The value of any shares issued in consideration for the Phase 2 Milestone Consideration Amount shall be determined based the lower of (A)&#160;on the average of the closing trading prices of our Common Stock as reported on the Nasdaq Global Market for the &lt;span style="-sec-ix-hidden:Hidden_epI11PzKoUK86hI-0VE6Iw;"&gt;&lt;span style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:normal;font-weight:normal;"&gt;twenty&lt;/span&gt;&lt;/span&gt; (20) consecutive trading&#160;days immediately preceding the date of the occurrence of the Phase 2 Milestone Event or (B)&#160;$3.54.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;The future contingent payments related to the Regulatory Milestones are stock-based payments accounted for under FASB Accounting Standards Codification Topic 480, &lt;i style="font-style:italic;"&gt;Distinguishing Liabilities From Equity&lt;/i&gt; (&#x201c;ASC 480&#x201d;). Such stock-based payments are subject to a lock-up whereby 50% of the shares are released at 3&#160;months and 50% are released at 6&#160;months. The future contingent payments related to the Sales Milestones are predominately cash-based payments accounted for under FASB Accounting Standards Codification Topic 450, &lt;i style="font-style:italic;"&gt;Contingencies&lt;/i&gt;. Accordingly, the Company will recognize the Sales Milestones when the contingency is probable and the amount is reasonably estimated.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;On November&#160;3, 2020, the Company received acknowledgement from the Australian Government Department of Health on the Company&#x2019;s submitted clinical trial notification (&#x201c;CTN&#x201d;) which triggered the obligation to settle the IND Milestone payment to the former owners. As a result, on November&#160;19, 2020, the Company issued 1,694,906 shares of its Common Stock valued at $9.57 per share for the amount value of $13.6 million to the former Spitfire stockholders. Pursuant to the Spitfire Merger Agreement, the Company issued the shares within sixty days of the submission of the CTN, which was October&#160;29, 2020. From September&#160;30, 2020 through November 19, 2020, the date of issuance, the Company recognized a decrease in the fair value of the IND Milestone payment of $5.4 million to research and development expense and reclassified the balance in the contingent consideration liability associated with the fair value of the IND Milestone payment to equity in the Company&#x2019;s consolidated balance sheet. No Regulatory Milestones were achieved during the three months ended March 31, 2022. The Phase 2 Milestone was met on April 26, 2022. See Note 17 for further details.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt;"&gt;The Company estimates the future contingent consideration for the Regulatory Milestones based upon a Monte Carlo simulation valuation model that is risk adjusted based on the probability of achieving the milestones and a discount for lack of marketability. The Company remeasures the fair value of the contingent consideration at each reporting period. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;margin:0pt;"&gt;During the fourth quarter of 2020, the Company achieved the IND Milestone and paid the obligation in shares according to the calculation above.

The Pre-Funded Warrants are exercisable at any time, provided that each Pre-Funded Warrant holder will be prohibited from exercising such Pre-Funded Warrants into shares of the Company&#x2019;s common stock if, as a result of such exercise, the holder, together with its affiliates, would own more than 4.99% of the total number of shares of the Company&#x2019;s common stock then issued and outstanding, which&#160;percentage may change at the holders&#x2019; election to any other number less than or equal to 19.99% upon 61 days&#x2019; notice to the Company. The gross proceeds of this offering were approximately $132.2 million, which includes the exercise in full of the underwriters&#x2019; option to purchase an additional 750,000 shares of common stock, before deducting underwriting discounts and commissions and offering expenses during the third quarter of 2020. The net proceeds of this offering were approximately $124.0 million, after deducting underwriting discounts and commissions and offering expenses payable by the Company.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;The Company has assessed the Pre-Funded Warrants for appropriate equity or liability classification and determined that the Pre-Funded Warrants are freestanding instruments that do not meet the definition of a liability pursuant to ASC 480 and do not meet the definition of a derivative pursuant to FASB Accounting Standards Codification Topic 815, &lt;i style="font-style:italic;"&gt;Derivatives and Hedging&lt;/i&gt; (&#x201c;ASC 815&#x201d;). The Pre-Funded Warrants are indexed to the Company&#x2019;s common stock and meet all other conditions for equity classification under ASC 480 and ASC 815. Accordingly, the Pre-Funded Warrants are classified as equity and are accounted for as a component of additional paid-in capital at the time of issuance. As of March&#160;31,&#160;2022, 760,870 of the Pre-Funded Warrants were exercised, leaving 869,566 remaining Pre-Funded Warrants unexercised.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;At-the-Market Offerings&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;On February&#160;25, 2021, the Company entered into an Equity Distribution Agreement (the &#x201c;2021 Agreement&#x201d;) with Piper Sandler&#160;&amp;amp; Co., Evercore Group L.L.C. and B. Riley Securities,&#160;Inc., serving as sales agents (the &#x201c;Sales Agents&#x201d;) with respect to an at-the-market offerings program under which the Company may offer and sell, from time to time at its sole discretion, shares of its common stock, par value $0.0001 per share (the &#x201c;Common Stock&#x201d;), having an aggregate offering price of up to $125.0 million (the &#x201c;Shares&#x201d;) through the Sale Agents (the &#x201c;2021 Offering&#x201d;). Any Shares offered and sold in the 2021 Offering will be issued pursuant to the Company&#x2019;s Registration Statement on Form&#160;S-3 filed with the Securities and Exchange Commission (the &#x201c;SEC&#x201d;) on December&#160;31, 2020, which was declared effective on January&#160;11, 2021, the prospectus supplement relating to the 2021 Offering filed with the SEC on February&#160;25, 2021 and any applicable additional prospectus supplements related to the 2021 Offering that form a part of the Registration Statement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;During the three months ended March 31, 2022, the Company sold 335,485 shares of Common Stock under the 2021 Agreement resulting in approximately $3.0 million in net proceeds. As of March&#160;31,&#160;2022, the Company has sold in aggregate 5,135,939 shares of Common Stock under the 2021 Agreement resulting in approximately $67.8 million in net proceeds, with $55.0 million remaining available to be sold under the 2021 Agreement. As of March&#160;31,&#160;2022, the Company recorded approximately $0.1 million of offering costs which offset the proceeds received from the shares sold through March&#160;31,&#160;2022. The Company capitalized approximately $0.1 million of deferred offering costs which will offset future proceeds received under the 2021 Agreement.&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;font-style:italic;margin:0pt 0pt 12pt 0pt;"&gt;Exchange Agreement&lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;On February&#160;25, 2021, the Company entered into an exchange agreement (the &#x201c;Exchange Agreement&#x201d;) with an Investor and its affiliates (the &#x201c;Exchanging Stockholders&#x201d;), pursuant to which the Company exchanged an aggregate of 1,000,000 shares of the Company&#x2019;s common stock, par value $0.0001 per share, owned by the Exchanging Stockholders for pre-funded warrants (the &#x201c;Exchange Warrants&#x201d;) to purchase an aggregate of 1,000,000 shares of common stock (subject to adjustment in the event of any stock dividends and splits, reverse stock split, recapitalization, reorganization or similar transaction, as described in the Exchange Warrants), with an exercise price of $0.0001 per share. The Exchange Warrants did not have an expiration date and were exercisable at any time except that the Exchange Warrants could not be exercised by the Exchanging Stockholders if, after giving effect thereto, the Exchanging Stockholders would beneficially own more than 9.99% of the Company&#x2019;s common stock, subject to certain exceptions. In accordance with FASB Accounting Standards Codification Topic 505, &lt;i style="font-style:italic;"&gt;Equity&lt;/i&gt;, the Company recorded the retirement of the common stock exchanged as a reduction of common shares outstanding and a corresponding debit to additional paid-in-capital and accumulated deficit at the fair value of the Exchange Warrants on the issuance date. The Exchange Warrants were classified as equity in accordance with ASC 480 and the fair value of the Exchange Warrants was recorded as a credit to additional paid-in-capital and is not subject to remeasurement. The Company determined that the fair value of the Exchange Warrants is substantially similar to the fair value of the retired shares on the issuance date due to the negligible exercise price for the Exchange Warrants. As of March&#160;31,&#160;2022, the Exchange Warrants to purchase 1,000,000 shares were net exercised, resulting in the issuance of 999,984 shares of common stock. All of the Exchange Warrants were exercised in full.&lt;/p&gt;</alt:CommonStockTextBlock>

The contract, as amended, had a total value of up to $136.8 million to be used to fund clinical development of NasoShield. Under the contract, BARDA paid the Company a fixed fee and reimbursed certain costs for the research and development of an Ad5-vectored, protective antigen-based intranasal anthrax vaccine through cGMP manufacture and conduct of a Phase 1 clinical trial dose ranging assessment of safety and immunogenicity. The contract consisted of an initial base performance period providing approximately $30.9 million in funding for the period July&#160;2016 through December&#160;2021. BARDA had seven options to extend the contract to fund certain continued development and manufacturing activities for the anthrax vaccine, including Phase 2 clinical studies. Each option, if exercised by BARDA, would have provided additional funding ranging from approximately $1.1 million to $34.4 million for a three-year period beginning in 2021. For the three months ended March 31, 2021, the Company recognized approximately $0.2 million of grant revenue under the BARDA contract. For the three months ended March&#160;31,&#160;2022, the Company has recognized de minimis grant revenue related to the close-out of the BARDA contract. BARDA did not extend the contract beyond the end of December 2021.&lt;/p&gt;</alt:USGovernmentContractsAndGrantsTextBlock>

The Plaintiff amended the complaint in February 2020 to include Vipin K. Garg and David J. Drutz as defendants, in addition to the Company (Dr. Garg, Dr. Drutz, and the Company are collectively referred to as &#x201c;Defendants&#x201d;). In March 2020 the Defendants filed a motion to dismiss the complaint. The Court denied the motion without prejudice and allowed Plaintiff an opportunity to file an amended complaint. Plaintiff&#x2019;s second amended complaint was filed on April 17, 2020, and Defendants filed a motion to dismiss that complaint on May 1, 2020. A hearing on Defendants&#x2019; motion to dismiss was held on May 20, 2020. Plaintiff, who is representing himself, alleges five causes of action as follows: (1) Defendants&#x2019; alleged retention of Plaintiff&#x2019;s lab notebooks after the termination of his employment in 2012; (2) alleged plagiarism based on publishing an article without naming Plaintiff as an author; (3) use of the Adhigh System, which Plaintiff alleges he developed; (4) allegations that Defendants manipulated our stock and caused a decrease in value; and (5) allegations that the Defendants &#x201c;wast[ed] government grant money and poison[ed] science by leaving data to rot.&#x201d; On September 30, 2020, Plaintiff filed a motion titled &#x201c;Motion to Proscribe Defendants&#x2019; Allegedly Illegal Use of Plaintiff&#x2019;s AdHigh System in Altimmune&#x2019;s Human Clinical Trials,&#x201d; to which Defendants filed an opposition on October 13, 2020. The court has not yet ruled on that motion, which also remains pending. On November 6, 2020, Defendants filed a motion for summary judgment on the basis of lack of personal jurisdiction, insufficient service of process, and failure to state a claim. The court ruled on that motion on March 25, 2021, which dismissed the case on the basis of lack of personal jurisdiction. On December 1, 2020, the magistrate judge assigned to the case issued a report and recommendation that Defendants&#x2019; motion to dismiss of May 1, 2020 be granted and that this action be dismissed for lack of personal jurisdiction. Plaintiff filed objections to the report and recommendation on December 14, 2020, and the resolution of those objections by the district court remains pending. &lt;/p&gt;&lt;p style="font-family:'Times New Roman','Times','serif';font-size:10pt;text-align:justify;text-indent:36pt;margin:0pt 0pt 12pt 0pt;"&gt;In December 2021, the Plaintiff refiled the complaint in the United States District Court for the District of Maryland. On February 24, 2022, Defendants filed a memorandum containing a brief description of the planned motion and a concise summary of the factual and legal support for it. On the basis of that memorandum, the Court granted Defendants&#x2019; request to file a motion to dismiss and allowed Plaintiff an opportunity to file an amended complaint. &#160;Plaintiff&#x2019;s amended complaint was filed on March 3, 2022, and Defendants filed a motion to dismiss that complaint on April 4, 2022.

Also, the lifetime of a warrant is often measured in years, while the lifetime of a typical option is measured in months.
