To approve, on an advisory, non-binding basis, the compensation of our named executive officers;

To ratify the Audit Committee’s selection of Ernst & Young LLP as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024; and

To conduct any other business properly brought before the meeting or any adjournment or postponement thereof.

These items of business are more fully described in the Proxy Statement accompanying this Notice.

The record date for the meeting is April 19, 2024. Only shareholders of record at the close of business on that date may vote at the meeting or any adjournment thereof. We will first mail the Proxy Statement, accompanying proxy card and annual report to our shareholders on or about May 2, 2024.

PROXY STATEMENT
FOR THE 2024 ANNUAL MEETING OF SHAREHOLDERS
TO BE HELD ON JUNE 12, 2024

This Proxy Statement contains information related to the 2024 Annual Meeting of Shareholders (the “annual meeting” or the “meeting”) of Armata Pharmaceuticals, Inc. (“Armata,” the “Company,” “we,” “our” or “us”) to be held at 8:30 a.m. (Pacific Time) on Wednesday, June 12, 2024 at our principal executive offices at 5005 McConnell Avenue, Los Angeles, California 90066, and at any adjournments or postponements thereof. On or about May 2, 2024, we expect to begin mailing this Proxy Statement, accompanying proxy card and annual report to each holder of record of our common stock as of the close of business on April 19, 2024, the record date for the meeting. This Proxy Statement and accompanying proxy card summarize the information you need to know to vote by proxy or in person at the meeting. You do not need to attend the meeting in person in order to vote.

Background

On May 9, 2019, Armata, formerly known as AmpliPhi Biosciences Corporation and we refer to herein prior to the Merger as “AmpliPhi”, completed a merger (the “Merger”) with privately held C3J Therapeutics, Inc., a Washington corporation (“C3J”), in accordance with the terms of an Agreement and Plan of Merger and Reorganization, dated January 3, 2019, as amended on March 25, 2019, by and among AmpliPhi, a wholly owned subsidiary of AmpliPhi (“Merger Sub”) and C3J (the “Merger Agreement”). At the effective time of the Merger, each outstanding share of C3J common stock was converted into the right to receive 0.04932975 shares of Armata common stock, par value $0.01 per share (“common stock”) (after giving effect to the Reverse Split, as defined below) (the “Exchange Ratio”), and Merger Sub merged with and into C3J, with C3J surviving the Merger as a wholly-owned subsidiary of Armata. As a result of the Merger, C3J was considered the accounting acquirer of AmpliPhi because C3J’s shareholders retained a majority control of the combined company, Armata, subsequent to the Merger; therefore, the historical financial statements of the accounting acquirer, C3J, have become Armata’s historical financial statements.

Immediately prior to the consummation of the Merger, AmpliPhi effected a 1-for-14 reverse split (the “Reverse Split”) of its issued and outstanding shares of common stock and changed its name to “Armata Pharmaceuticals, Inc.” On May 10, 2019, Armata’s common stock began trading on a split-adjusted basis on the NYSE American exchange under the ticker symbol “ARMP.” All shares and per share amounts in this Proxy Statement reflect the Reverse Split unless otherwise noted.

Immediately following the closing of the Merger, certain shareholders of C3J prior to the Merger (the “Investors”) purchased shares of common stock of Armata in a private placement for an aggregate purchase price of $10.0 million (the “Financing”). After the Merger and such concurrent private placement, the former C3J security holders owned approximately 76% of the aggregate number of shares of Armata’s common stock and the security holders of AmpliPhi as of immediately prior to the Merger owned approximately 24% of the aggregate number of shares of Armata’s common stock.

This Proxy Statement includes certain historical information relating to the Board of Directors, executive officers and governance arrangements of the Company during periods ended prior to the completion of the Merger. This Proxy Statement also includes certain disclosures concerning the Company’s Board and officers currently in office. We use the term “AmpliPhi” in this Proxy Statement to refer to the Company prior to the Merger, and all references to “C3J” refer to C3J Therapeutics, Inc. and its business prior to the closing of the Merger. All references to “Armata,” the “Company,” “we,” “us” or “our” in this Proxy Statement mean Armata Pharmaceuticals, Inc., the combined company.

QUESTIONS AND ANSWERS ABOUT THESE PROXY MATERIALS AND VOTING

Why am I receiving these materials?

The Board of Directors is soliciting your proxy to vote at the annual meeting including at any adjournments or postponements of the meeting. Beginning on or about May 2, 2024, we will send you by mail a copy of this Proxy Statement, the proxy card and the annual report. You are invited to attend the annual meeting to vote on the proposals described in this Proxy Statement. However, you do not need to attend the annual meeting to vote your shares. Instead, you may simply complete, sign and return the enclosed proxy card, or follow the instructions on the enclosed proxy card to submit your proxy to vote your shares via telephone or on the internet.

How do I attend the meeting?

The meeting will be held at 8:30 a.m. (Pacific Time) on Wednesday, June 12, 2024 at our principal executive offices at 5005 McConnell Avenue, Los Angeles, California 90066. Information on how to vote in person at the meeting is discussed below.

Who can vote at the meeting?

Only shareholders of record at the close of business on April 19, 2024 will be entitled to vote at the meeting. On this record date, there were 36,154,617 shares of common stock outstanding and entitled to vote.

Shareholder of Record: Shares Registered in Your Name: If on the record date your shares were registered directly in your name with Armata’s transfer agent, Computershare, Inc., then you are a shareholder of record. As a shareholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the annual meeting, we urge you to vote your shares by completing, signing and returning the enclosed proxy card, or following the instructions on the enclosed proxy card to submit your proxy to vote your shares via telephone or on the internet.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank: If on the record date your shares were held, not in your name, but rather in an account at a brokerage firm, bank, dealer or other similar organization, then you are the beneficial owner of shares held in “street name” and our proxy materials are being forwarded to you by that organization. The broker, bank, or other agent holding your account is considered to be the shareholder of record for purposes of voting at the meeting. As a beneficial owner, you have the right to direct your broker, bank or other agent regarding how to vote the shares in your account. You are also invited to attend the meeting. However, since you are not the shareholder of record, you may not vote your shares in person at the meeting unless you request and obtain a valid proxy from your broker, bank, or other agent.

What am I voting on?

There are three matters scheduled for a vote:

•

Proposal 1: To elect seven nominees for director, named in this Proxy Statement, to serve one-year terms expiring at the 2025 Annual Meeting of Shareholders and upon their successors being duly elected and qualified;

•

Proposal 2: Approval of, on an advisory, non-binding basis, the compensation of our named executive officers; and

•

Proposal 3: Ratification of the Audit Committee’s selection of Ernst & Young LLP (“Ernst & Young”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024.

What if another matter is properly brought before the meeting?

The Board of Directors knows of no other matters that will be presented for consideration at the meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on those matters in accordance with their best judgment.

How do I vote?

For the election of directors (Proposal 1), you may either vote “For” the nominees to the Board of Directors or you may “Withhold” your vote for any nominee you specify.

For the approval of, on an advisory, non-binding basis, the compensation of our named executive officers (Proposal 2), you may either vote “For” or “Against” the proposal.

For ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2024 (Proposal 3), you may vote “For” or “Against” or abstain from voting.

Shareholder of Record: Shares Registered in Your Name

If you are a shareholder of record, you may vote in person at the meeting or vote by proxy. Whether or not you plan to attend the annual meeting, we urge you to vote your shares by completing, signing and dating the enclosed proxy card and returning it in the postage-paid envelope provided. For your convenience, you may also vote your shares via the internet or by a toll-free telephone number by following the instructions on the enclosed proxy card. Authorizing your proxy over the internet, by mailing a proxy card or by telephone will not limit your right to attend the meeting and vote your shares in person.

To vote in person, come to the meeting and we will give you a ballot when you arrive.

To vote through the internet, go to www.envisionreports.com/ARMP to complete an electronic proxy card. You will be asked to provide the control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. (Pacific Time) on June 11, 2024 to be counted.

To vote using the proxy card, simply complete, sign and date the enclosed proxy card and return it promptly in the postage-paid envelope provided. If you return your signed proxy card to us before the meeting, we will vote your shares as you direct.

To vote over the telephone, dial toll-free 1-800-652-8683 using a touch-tone phone and follow the recorded instructions. You will be asked to provide the control number from the enclosed proxy card. Your vote must be received by 11:59 p.m. (Pacific Time) on June 11, 2024 to be counted.

Your proxy (one of the individuals named in your proxy card) will vote your shares per your instructions. If you are a shareholder of record, your shares will not be voted if you do not vote by internet or telephone, return your proxy card by mail or vote in person at the meeting as described above; however, if you properly submit a proxy, but do not specify your voting choice on one or more of the proposals included thereon, your shares will be voted, as recommended by the Board of Directors: (1) to elect to our Board of Directors the director nominees named in this Proxy Statement and (2) to ratify the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2024.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you have shares held by a broker, bank or other agent, you may instruct your agent to vote your shares by following the instructions that such agent provides to you. Most brokers and nominees allow you to vote by mail, telephone and on the internet.

As discussed further below, under NYSE American exchange rules, the election of directors (Proposal 1) and the vote to approve the compensation of our named executive officers (Proposal 2) are considered “non-routine” matters, meaning that brokers, banks, or other agents who have not been furnished voting instructions from their clients will not be authorized to vote in their discretion on these proposals.

The ratification of the appointment of Ernst & Young as our independent registered public accounting firm for the year ending December 31, 2024 (Proposal 3) is considered a “routine” matter, meaning that brokers, banks, or other agents who have not been furnished voting instructions from their clients will be authorized to vote on that proposal.

To vote in person at the meeting, you must obtain a valid proxy from your broker, bank or other agent. Follow the provided instructions from your broker or bank, or contact your broker or bank to request a proxy form.

We provide internet proxy voting to allow you to vote your shares online, with procedures designed to ensure the authenticity and correctness of your proxy vote instructions. However, please be aware that you must bear any costs associated with your internet access, such as usage charges from internet access providers and telephone companies.

How many votes do I have?

On each matter to be voted upon, you have one vote for each share of common stock you owned as of the close of business on the record date.

What happens if I do not vote?

Shareholder of Record: Shares Registered in Your Name

If you are a shareholder of record and do not vote through the internet, by completing your proxy card, by telephone or in person at the meeting, your shares will not be voted.

Beneficial Owner: Shares Registered in the Name of Broker or Bank

If you are a beneficial owner and do not instruct your broker, bank, or other agent how to vote your shares, the question of whether such agent will still be able to vote your shares depends on whether the NYSE American exchange deems the particular proposal to be a “routine” matter. Brokers, banks and other agents can use their discretion to vote “uninstructed” shares with respect to matters that are considered to be “routine,” but not with respect to “non-routine” matters. Under the rules and interpretations of the NYSE American exchange, “non-routine” matters are matters that may substantially affect the rights or privileges of shareholders, such as mergers, shareholder proposals, elections of directors (even if not contested), and certain corporate governance proposals, even if management-supported. For these “non-routine” matters for which a broker, bank or other agent has not received voting instructions, a “broker non-vote” occurs. Accordingly, your broker, bank or other agent may not vote your shares on Proposal 1 or Proposal 2 without your instructions (resulting in “broker non-votes” for such matters), but may vote your shares on Proposal 3 even in the absence of your instruction.

What if I return a proxy card or otherwise vote but do not make specific choices?

If you return a signed and dated proxy card or otherwise vote without marking your voting selections, your shares will be voted, as applicable: “For” Proposal 1, the election of nominees for director; “For” Proposal 2, the approval of, on an advisory, non-binding basis, the compensation of our named executive officers; and “For” Proposal 3, the ratification of the Audit Committee’s selection of Ernst & Young as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024. If any other matter is properly presented at the meeting, your proxyholder (one of the individuals named on your proxy card) will vote your shares using his or her best judgment.

Who is paying for this proxy solicitation?

We will pay for the entire cost of soliciting proxies and have paid the entire expense of preparing, printing and mailing this Proxy Statement, the proxy card and any additional materials furnished to shareholders. In addition to solicitations by mail, our officers, directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Any officers, directors and employees will not be paid any additional compensation for soliciting proxies. We may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

What does it mean if I receive more than one set of proxy materials?

If you receive more than one set of proxy materials, your shares may be registered in more than one name or in different accounts. Please follow the voting instructions in each proxy card in the proxy materials to ensure that all of your shares are voted.

Can I change my vote or revoke my proxy after I have voted?

Shareholder of Record: Shares Registered in Your Name: Yes. You may revoke your proxy and change your vote at any time before the final vote at the meeting. The cutoff time for voting through the internet or by telephone will be 11:59 p.m. (Pacific Time) on June 11, 2024, the day before the meeting. You may change your vote on the internet or by telephone (only your latest internet or telephone proxy submitted prior to the meeting will be counted); by signing and returning a new proxy card with a later date; by sending a timely written notice that you are revoking your proxy to our Secretary at Armata Pharmaceuticals, Inc., 5005 McConnell Avenue, Los Angeles, California 90066; or by attending the meeting and voting in person. However, your attendance at the meeting will not automatically revoke your proxy unless you vote again at the meeting or specifically request in writing that your prior proxy be revoked.

Beneficial Owner: Shares Registered in the Name of Broker or Bank: If your shares are held by your broker or bank as a nominee or agent, you should follow the instructions provided by your broker or bank.

When are shareholder proposals and director nominations due for next year’s annual meeting?

To be considered for inclusion in next year’s proxy materials, your proposal must be submitted in writing to our Secretary at Armata Pharmaceuticals, Inc., 5005 McConnell Avenue, Los Angeles, California 90066 by December 30, 2024, or, if the date of our 2025 Annual Meeting of Shareholders has changed by more than 30 days from the one-year anniversary of the date of this year’s annual meeting, by a date that constitutes a reasonable time before we print and send our proxy materials to shareholders, which date will be disclosed in a report filed by us with the SEC. Any such proposals must meet the requirements of Rule 14a-8 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

If you wish to submit a proposal (including a director nomination) at the annual meeting that will not already be included in next year’s annual meeting proxy materials, your proposal generally must be submitted in writing to the same address not fewer than 60 nor more than 90 days prior to the date approved by the Board of Directors to hold the 2025 Annual Meeting of Shareholders; provided, that if we provide less than 60 days’ notice of such date, your proposal (including a director nomination) must be received by our Secretary not later than the tenth day following the day on which the notice of the date of the 2025 Annual Meeting of Shareholders is mailed or publicly disclosed. If the facts warrant, the Board of Directors, or the chairman of an annual meeting of shareholders, may determine and declare that a proposal does not constitute proper business to be transacted at the meeting or that business was not properly brought before the meeting in accordance with our Amended and Restated Bylaws (“Bylaws”) and, if, in either case, it is so determined, any such business shall not be transacted. Please review our Bylaws, which contain additional requirements regarding advance notice of shareholder proposals and nominations. In addition to satisfying the foregoing requirements under our Bylaws, to comply with the universal proxy rules in connection with our 2025 annual meeting, shareholders who intend to solicit proxies in support of director nominees other than our nominees must provide notice to us that sets forth the information required by Rule 14a-19 under the Exchange Act no later than April 14, 2025.

As provided in the Current Report filed on Form 8-K for the annual meeting, for a shareholder’s notice to be timely presented at this annual meeting, it must have been received by our Secretary by April 1, 2024.

How are votes counted?

Votes generally. Votes will be counted by the inspector of election appointed for the meeting, who will separately count, for the proposal to elect directors, votes “For,” “Withhold” and broker non-votes; and, with respect to other proposals, votes “For” and “Against,” abstentions and, if applicable, broker non-votes.

Abstentions and Broker Non-Votes. Abstentions will count towards the quorum. Shares constituting broker non-votes are not counted or deemed to be present or represented for the purpose of determining whether shareholders have approved a matter, but they are counted as present for the purpose of determining a quorum at the meeting.

Required Vote. The following table summarizes the minimum vote needed to approve each proposal and the effect of abstentions and broker non-votes.

What is the quorum requirement?

A quorum of shareholders is necessary to hold a valid meeting. A quorum will be present if shareholders holding at least a majority of the outstanding shares entitled to vote on a matter and be counted collectively upon such matter are present at the meeting in person or represented by proxy. On the record date, there were 36,154,617 shares outstanding and entitled to vote. Thus, the holders of 18,077,309 shares must be present in person or represented by proxy at the meeting to have a quorum.

Your shares will be counted towards the quorum only if you submit a valid proxy (or one is submitted on your behalf by your broker, bank or other agent) or if you vote in person at the meeting. Abstentions and broker non- votes will be counted towards the quorum requirement. If there is no quorum, the holders of a majority of shares at the meeting in person or represented by proxy may adjourn the meeting to another date.

How can I find out the results of the voting at the meeting?

Preliminary voting results will be announced at the meeting. In addition, final voting results will be published in a current report on Form 8-K that we expect to file within four business days after the meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the meeting, we intend to file a Form 8- K to publish preliminary results and, within four business days after the final results are known to us, file an amended Form 8-K to publish the final results.

What proxy materials are available on the internet?

The Proxy Statement and annual report to shareholders are available at https://investor.armatapharma.com/annual-reports-and-proxy.

Why is the executive compensation proposal (Proposal 2) included among the items to be considered at the Annual Meeting?

We have included the executive compensation proposal (Proposal 2) among the items to be considered at the meeting in order to satisfy the requirements of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 and Section 14A of the Exchange Act of 1934.

PROPOSAL 1

Election of Directors

Our business and affairs are organized under the direction of our Board of Directors. The primary responsibilities of our Board of Directors are to provide oversight, strategic guidance, counseling and direction to our management. Our Board of Directors meets on a regular basis and on an ad hoc basis as required.

Our Bylaws provide that the Board of Directors will consist of not less than one nor more than nine members, as fixed from time to time by a resolution of the Board or shareholders. The Board of Directors currently has seven members, all of whom have been re-nominated by the Board of Directors to stand for election at the annual meeting.

Directors are elected by a plurality of the votes of the holders of shares present in person or represented by proxy and entitled to vote on the election of directors. Accordingly, the seven nominees receiving the highest number of affirmative votes at this annual meeting will be elected. Shares represented by executed proxies will be voted, if authority to do so is not withheld, for the election of the seven nominees named below. If any nominee becomes unavailable for election as a result of an unexpected occurrence, shares that would have been voted for that nominee will instead be voted for the election of a substitute nominee proposed by the Board of Directors. Each person nominated for election has agreed to serve if elected. The Company’s management has no reason to believe that any nominee will be unable to serve.

Under our current Bylaws, any vacancy occurring on the Board of Directors may be filled by the shareholders, the Board of Directors or, if the directors in office constitute fewer than a quorum, by the affirmative vote of a majority of the remaining directors.

The Board of Directors Recommends
a Vote “For” each Named Nominee.

INFORMATION REGARDING THE BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Independence of the Board of Directors

As required under the NYSE American exchange listing standards, a majority of the members of a listed company’s Board of Directors must qualify as “independent,” as affirmatively determined by the Board of Directors. Our Board of Directors consults with our counsel to ensure that the Board of Directors’ determinations are consistent with relevant securities and other laws and regulations regarding the definition of “independent,” including those set forth in pertinent listing standards of the NYSE American exchange, as in effect from time to time.

Consistent with these considerations, after review of all relevant identified transactions or relationships between each director, or any of his or her family members, and us, our senior management and our independent auditors, the board affirmatively determined that all of the director nominees except for Deborah Birx are independent directors within the meaning of the applicable NYSE American exchange listing standards. In making this determination, our board found that none of these directors or nominees for director had a material or other disqualifying relationship with us. The Board of Directors concluded that Dr. Birx is not an independent director within the meaning of the applicable NYSE American exchange listing standards. Dr. Birx is not an independent director under these rules given her role as our Chief Executive Officer.

As required under applicable NYSE American exchange rules, we anticipate that our independent directors will meet in regularly scheduled executive sessions at which only independent directors are present.

Our Bylaws provide that the Board of Directors will consist of not less than one nor more than nine members, as fixed from time to time by a resolution of the Board of Directors. The authorized size of our Board of Directors is currently eight members.

Board Leadership Structure

Our Board of Directors has an independent Chair, Robin C. Kramer, who has authority, among other things, to call and preside over board meetings, to set meeting agendas and to determine materials to be distributed to the Board of Directors. Accordingly, the Chair has substantial ability to shape the work of the Board of Directors. We have a separate chair for each committee of the Board of Directors. As a general policy, the Board of Directors believes that separation of the positions of Chair and Chief Executive Officer reinforces the independence of the Board of Directors from management, creates an environment that encourages objective oversight of management’s performance and enhances the effectiveness of the Board of Directors as a whole. We expect and intend the positions of Chair of the Board of Directors and Chief Executive Officer to continue to be held by separate individuals in the future.

Role of the Board in Risk Oversight

One of the principal functions of our Board of Directors is to provide oversight concerning the assessment and management of risk related to our business. The Board of Directors is involved in risk oversight through direct decision-making authority with respect to fundamental financial and business strategies and major corporate activities.

While the Board of Directors oversees our risk management, our management is responsible for day-to-day risk management processes, including, without limitation, strategic, operational, financial, regulatory and cyber-security risks that may exist from time to time. The Board of Directors expects management to consider the risks of, and risk management in, each business decision, to proactively develop and monitor risk management strategies and processes for day-to-day activities and to effectively implement risk management strategies adopted by the Board of Directors and its committees. In connection with this responsibility, members of management provide regular reports to the Board of Directors regarding business operations and strategic planning, financial planning and budgeting and regulatory matters, including any material risk to our company related to such matters. Although the Board of Directors does not have a formal risk oversight policy, the Board of Directors does, as a whole and through its various committees, oversee the proper functioning of our internal risk management processes. In its risk oversight role, the Board

of Directors evaluates whether management has reasonable controls in place to address material risks we currently face and those we may face in the future.

The Board of Directors has delegated oversight for specific areas of risk exposure to committees of the Board of Directors as follows:

•

The Audit Committee is primarily responsible for overseeing our financial risk management processes on behalf of the Board of Directors. The Audit Committee is responsible for discussing our overall risk assessment and risk management policies with management and our independent registered public accounting firm, as well as our plans to monitor and control any financial risk exposure. The Audit Committee is also responsible for primary risk oversight related to our internal control over financial reporting, disclosure controls and procedures, and legal and regulatory compliance. In addition, the Audit Committee reviews all related-person transactions, including the risks related to those transactions impacting our company. The Audit Committee further oversees the Company’s cybersecurity programs and policies, as well as monitors cybersecurity risks and potential breach incidents. Going forward, we expect that the Audit Committee will receive reports from management regarding its assessment of risks at least quarterly.

•

The Compensation Committee oversees our compensation programs and reviews the conduct incentivized by those programs, including any impact on risk-taking by our executive officers and employees.

•

The Nominating and Corporate Governance Committee oversees the organization, membership and structure of our Board of Directors and our corporate governance practices. The committee members report to the full Board of Directors on material developments in their areas of oversight.

•

The Special Committee evaluates strategic transactions which may involve Innoviva, Inc. or affiliates thereof.

We believe this division of responsibilities is the most effective approach for addressing the risks we face and that our Board of Directors’ leadership structure, which also emphasizes the independence of our Board of Directors in its oversight of our business and affairs, supports this approach.

The Board of Directors and its committees meet at regularly scheduled and special meetings throughout the year at which management reports to the board concerning the results of our risk management activities, as well as external changes that may change the levels of business risk to which we are exposed. At each regular meeting of our Board of Directors, the chairperson of each committee reports to the full board regarding the matters reported and discussed at any committee meetings, including any matters related to risk assessment or risk management. Upon the request of the committees, our principal executive officer and principal financial officer attend meetings of these committees when they are not in executive session, and often report on matters that may not be otherwise addressed at these meetings. In addition, our directors are encouraged to communicate directly with members of management regarding matters of interest, including matters related to risk, at times when meetings are not being held.

Meetings of the Board of Directors

During 2023, our Board of Directors met eight times, the Audit Committee met seven times, the Compensation Committee met five times, the Nominating and Corporate Governance Committee met once, and the Special Committee met seven times. Each Board member attended 75% or more of the total number of meetings of the Board and of the committees on which he or she served, that were held during the portion of the last fiscal year for which he or she was a director or committee member.

As required under applicable NYSE American exchange listing standards, during 2023, our independent directors met on a regular basis in executive session without the presence of non-independent directors and management.

Each director is expected to devote the time necessary to appropriately discharge his or her responsibilities and to rigorously prepare for and attend and participate in all Board meetings and meetings of Board committees on which he or she serves. In addition, the independent directors meet regularly in executive session without the presence of management.

Policy Concerning Director Attendance at Annual Meetings of Shareholders

There is no formal policy as to their attendance at annual meetings of shareholders, and in the past our directors have not been present for such meetings.

Information Regarding Committees of the Board of Directors

The Board of Directors has an Audit Committee, a Compensation Committee, a Nominating and Corporate Governance Committee and a Special Committee. Each of the Audit Committee, Compensation Committee and Nominating and Corporate Governance Committee operates under a written charter, the adequacy of which each respective committee regularly reviews and reassesses. A copy of each charter is available under the heading “Corporate Governance” of the Investor Relations section of our website at https://investor.armatapharma.com/corporate-governance. Our Board of Directors may establish additional committees from time to time in accordance with our Bylaws.

As of April 19, 2024, the record date, the membership of the standing committees was as follows:

Report of the Audit Committee of the Board of Directors

The material in this report is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any filing of the Company under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing.

Compensation Committee Processes and Procedures

Generally, the Compensation Committee meets quarterly and with greater frequency if necessary. The agenda for each meeting is usually developed by the Chair of the Compensation Committee, in consultation with the Chief Executive Officer. The Compensation Committee meets regularly in executive session.

However, from time to time, various members of management and other employees, as well as outside advisors or consultants, may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Chief Executive Officer may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his or her compensation or individual performance objectives. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. Other than in-house legal counsel and certain other types of advisors, the Compensation Committee may retain such consultants or advisors only after taking into consideration six factors, prescribed by the SEC and NYSE American exchange, that bear upon the advisor’s independence; however, there is no requirement that any advisor be independent. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisors engaged for the purpose of advising the Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms.

Historically, the Compensation Committee has made most of the significant adjustments to annual compensation, determined bonus and equity awards and established new performance objectives at one or more meetings held during the fourth quarter of the preceding year or during the first quarter of the year, following an evaluation of calendar year results. However, the Compensation Committee also considers matters related to individual compensation, such as compensation for new executive hires, as well as high-level strategic issues, such as the efficacy of the Company’s compensation strategy, potential modifications to that strategy and new trends, plans or approaches to compensation, at various meetings throughout the year. Generally, the Compensation Committee’s process comprises two related elements: the determination of compensation levels and the establishment of performance objectives for the current year. For executives other than the Chief Executive Officer, the Compensation Committee solicits and considers evaluations and recommendations submitted to the Committee by the Chief Executive Officer. In the case of the Chief Executive Officer, the evaluation of his or her performance is conducted by the Compensation Committee, which determines any adjustments to his or her compensation, as well as awards to be granted. For all executives and directors as part of its deliberations, the Compensation Committee may review and consider, as appropriate, materials such as financial reports and projections, operational data, tax and accounting information, tally sheets that set forth the total compensation that may become payable to executives in various hypothetical scenarios, executive and director stock ownership information, company stock performance data, analyses of historical executive compensation levels and current Company-wide compensation levels and recommendations of the Compensation Committee’s compensation consultant, if any, including analyses of executive and director compensation paid at other peer companies identified by the consultant.

Nominating and Corporate Governance Committee

Our Board of Directors has determined that each of the members of this committee satisfies the NYSE American exchange listing independence requirements. The Nominating and Corporate Governance Committee of the Board of Directors is responsible for, among other things:

•

identifying, reviewing and evaluating candidates to serve on our Board of Directors consistent with criteria approved by our Board of Directors;

•

assessing the performance of management and the Board of Directors, including board committees, seeking input from senior management, the full Board of Directors and others, which assessment shall include, among other things, an evaluation of the board’s contribution as a whole and overall board composition and makeup, including the reelection of current board members;

•

evaluating, nominating and recommending individuals for membership on our Board of Directors;

•

evaluating nominations by shareholders of candidates for election to our Board of Directors;

•

considering and assessing the independence of members of our Board of Directors;

•

developing a set of corporate governance policies and principles, periodically reviewing and assessing these policies and principles and their application and recommending to our Board of Directors any changes to such policies and principles;

•

reviewing the adequacy of its charter on an annual basis; and

•

reviewing and assessing on an annual basis its own performance.

The Nominating and Corporate Governance Committee believes that candidates for director should, both individually and collectively, have the integrity, experience, judgment, commitment (including having sufficient time to devote to us and a sufficient level of participation), skills, diversity and expertise appropriate for our Company. We do not have a set policy or process for considering “diversity,” however that term may be defined, in identifying nominees. However, the Nominating and Corporate Governance Committee strives to identify and recruit individuals whose diverse talents, experiences and backgrounds enhance the inclusive environment in which the Board currently functions. In assessing the directors, both individually and collectively, the Nominating and Corporate Governance Committee may consider our current needs and the needs of our Board of Directors, to maintain a balance of knowledge, experience and capability in various areas. However, the Nominating and Corporate Governance Committee retains the right to modify these qualifications from time to time. In the case of new director candidates, the Nominating and Corporate Governance Committee also determines whether the nominee is independent for NYSE American exchange purposes, which determination is based upon applicable NYSE American exchange listing standards, applicable SEC rules and regulations and the advice of counsel, if necessary. The Nominating and Corporate Governance Committee may use its network of contacts to compile a list of potential director candidates, but may also engage, if it deems appropriate, a professional search firm. The Nominating and Corporate Governance Committee conducts any appropriate and necessary inquiries into the backgrounds and qualifications of possible candidates after considering the function and needs of the Board of Directors. The Nominating and Corporate Governance Committee meets to discuss and consider the candidates’ qualifications and then selects a nominee for recommendation to the Board of Directors by majority vote.

The Nominating and Corporate Governance Committee will consider director candidates recommended by shareholders. The Nominating and Corporate Governance Committee does not alter the manner in which it evaluates candidates, including the criteria set forth above, based on whether or not the candidate was recommended by a shareholder. As provided in the Current Report filed on Form 8-K on March 22, 2024 for the 2024 Annual Meeting, for a shareholder’s written recommendations to be timely presented at this annual meeting, it must have been received by our Secretary at our principal executive offices at 5005 McConnell Avenue, Los Angeles, California 90066 by April 1, 2024. Submissions must include the name and address of the shareholder on whose behalf the submission is made; the number of shares of our common stock that are owned beneficially by such shareholder as of the date of the submission; the full name of the proposed candidate; a description of the proposed candidate’s business experience for at least the previous five years; complete biographical information for the proposed candidate; and a description of the proposed candidate’s qualifications as a director. Any such submission must be accompanied by the written consent of the proposed candidate to be named as a nominee and to serve as a director if elected.

Special Committee

The Special Committee is comprised of independent directors who are not affiliated with Innoviva, Inc. The committee investigates, evaluates, and, as applicable, provides recommendations to the Company’s Board regarding financing, credit support and other kinds of potential strategic transactions which may involve Innoviva, Inc., the Company’s largest shareholder.

Shareholder Communications with the Board of Directors

The Company’s Board has adopted a formal process by which shareholders may communicate with the Board or any of its committees or directors. Shareholders who wish to communicate with the Board may do so by sending written communications addressed to the Secretary of the Company at Armata Pharmaceuticals, Inc., 5005 McConnell Avenue, Los Angeles, California 90066. All communications will be compiled and reviewed by the Secretary of the Company, who will determine whether the communication should be presented to the Board, committee or individual director, as applicable. Communications approved by the Secretary will be submitted to the Board of Directors, its committees, or the individual directors on a periodic basis. The purpose of this screening is to allow the Board to avoid having to consider irrelevant or inappropriate communications (such as advertisements, solicitations and hostile communications). All communications directed to the Audit Committee in accordance with the Company’s Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters (the “Whistleblower Policy”), discussed below, will be treated in accordance with that policy.

Any interested person may, however, communicate directly with the Chair or the independent directors as a group. Persons interested in communicating directly with the independent directors regarding their concerns or issues may do so by addressing correspondence to a particular director, or to the independent directors generally, in care of Armata Pharmaceuticals, Inc. at 5005 McConnell Avenue, Los Angeles, California 90066. If no particular director is named, letters will be forwarded, depending upon the subject matter, to the Chair of the Audit, Compensation, or Nominating and Corporate Governance Committee.

Code of Ethics

We have adopted a code of ethics for directors, officers (including our principal executive officer, principal financial officer and principal accounting officer) and employees, known as the Code of Business Conduct and Ethics. The Code of Business Conduct and Ethics is available under the heading “Corporate Governance” of the Investor Relations section of our website at https://investor.armatapharma.com/corporate-governance. Any amendment to, or waiver from, a provision of the codes of ethics applicable to our directors and executive officers will be disclosed in a current report on Form 8-K within four business days following the date of the amendment or waiver, unless the rules of the NYSE American exchange then permit website posting of such amendments and waivers, in which case we would promptly post such disclosures on our internet website.

Open Door Policy for Reporting Complaints Regarding Accounting and Auditing Matters

We have adopted the Whistleblower Policy to facilitate the receipt, retention and treatment of complaints regarding accounting, internal accounting controls or auditing matters, as well as the confidential, anonymous submission by our employees of concerns regarding these matters.

Hedging and Pledging Policy

Our insider trading policy prohibits our officers, other employees and directors from hedging or pledging our shares.

PROPOSAL 2

Advisory, Non-Binding Vote to Approve the Compensation of Our Named Executive Officers

Section 14A of the Exchange Act requires that we provide our shareholders with the opportunity to vote to approve, on a non-binding, advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Our compensation programs are designed to effectively align our executives’ interests with the interests of our shareholders by focusing on long-term equity incentives that correlate with the growth of sustainable long-term value for our shareholders. Shareholders are urged to read the section titled “Executive Compensation” in this Proxy Statement, which contains tabular information and narrative discussion about the compensation of our named executive officers. Our Compensation Committee believes that the objectives of our executive compensation program, as they relate to our named executive officers, are appropriate for a company of our size and stage of development and that our compensation policies and practices help meet those objectives. In addition, our Compensation Committee believes that our executive compensation program, as it relates to our named executive officers, achieves an appropriate balance between fixed compensation and variable incentive compensation. Our Board of Directors and our Compensation Committee believe that our policies and practices are effective in implementing our compensation philosophy and in achieving our compensation program goal. Accordingly, we are asking our shareholders to approve the compensation of our named executive officers.

The vote on this resolution is not intended to address any specific element of compensation; rather, the vote relates to the compensation of our named executive officers, as described in this Proxy Statement in accordance with the compensation disclosure rules of the SEC.

Based on the above, we request that shareholders indicate their support, on a non-binding advisory basis, for the compensation of our named executive officers as described in this Proxy Statement by voting “FOR” the following resolution:

“RESOLVED, that the shareholders of Armata Pharmaceuticals, Inc. approve, on an advisory basis, the compensation paid to Armata Pharmaceuticals, Inc.’s named executive officers, as disclosed pursuant to the compensation disclosure rules of the U.S. Securities and Exchange Commission, including the Executive Compensation section, the compensation tables and the narrative discussion in Armata Pharmaceuticals, Inc.’s 2024 proxy statement.”

As an advisory vote, this Proposal 2 is non-binding. Although the vote is non-binding, our Board of Directors and our Compensation Committee value the opinions of our shareholders and will consider the outcome of the vote when making future compensation decisions for our named executive officers.

The Board of Directors Recommends
a Vote “For” Proposal 2.

PROPOSAL 3

Ratification of Selection of Independent Registered Public Accounting Firm

Proposal to Ratify Appointment of Ernst & Young LLP

The Audit Committee of the Board of Directors has selected Ernst & Young as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2024 and has further directed that management submit the selection of its independent registered public accounting firm for ratification by the shareholders at the meeting. Ernst & Young served as the independent registered public accounting firm for AmpliPhi from January 20, 2015 until the completion of the Merger and has continued to serve in such role for Armata following the Merger. The Merger was treated as a reverse acquisition for accounting purposes and, as such, the historical financial statements of the accounting acquirer, C3J, have become Armata’s historical financial statements.

Representatives of Ernst & Young are expected to be available at the meeting. They will have an opportunity to make a statement if they so desire and will be available to respond to appropriate questions.

Neither our Bylaws nor other governing documents or law require shareholder ratification of the selection of Ernst & Young as the Company’s independent registered public accounting firm. However, the Audit Committee of the Board is submitting the selection of Ernst & Young to the shareholders for ratification as a matter of good corporate practice. If the shareholders fail to ratify the selection, the Audit Committee of the Board will reconsider whether or not to retain Ernst & Young. Even if the selection is ratified, the Audit Committee of the Board in its discretion may direct the appointment of different independent auditors at any time during the year if it determines that such a change would be in the best interests of the Company and its shareholders.

In order for Proposal 3 to be approved, the number of shares cast “For” the proposal must exceed the number of shares cast “Against” the proposal. Abstentions and broker non-votes, if any, will have no effect on the outcome of the vote.

Principal Accountant Fees and Services

The following table represents aggregate fees incurred for Ernst & Young LLP services for the years ended December 31, 2023 and 2022:

	Fiscal Year Ended December 31, 2023			Fiscal Year Ended December 31, 2022
Armata Pharmaceuticals, Inc.
Audit Fees		$	693,000		$	415,000
Audit Related Fees			37,000			26,000
Tax Fees			—			—
All Other Fees			10,000			10,000
Total		$	740,000		$	451,000

Representatives of Ernst & Young LLP attended the majority of the meetings of the Audit Committee occurring during the years ended December 31, 2023 and 2022.

Pre-Approval Policies and Procedures

The Audit Committee approves in advance the engagement and fees of the independent registered public accounting firm for all audit services and non-audit services, based upon independence, qualifications and, if applicable, performance. The Audit Committee may form and delegate to subcommittees of one or more members of the Audit Committee the authority to grant pre-approvals for audit and permitted non-audit services, up to specific amounts. All audit services provided by Ernst & Young LLP for the periods presented were pre-approved by the Audit Committee.

Ability to Continue as a Going Concern

The report of Ernst & Young on the consolidated financial statements of Armata Pharmaceuticals, Inc. for the fiscal year ended December 31, 2023, included in Armata’s Annual Report on Form 10-K, filed on March 21, 2024, stated that Armata has suffered recurring losses and negative cash flows from operations, which raised substantial doubt about Armata’s ability to continue as a going concern. Other than the foregoing, Ernst & Young’s report on our financial statements for the past two years contained no adverse opinion or disclaimer of opinion and was not qualified as to audit scope or accounting principles.

The Board of Directors Recommends
a Vote “For” Proposal 3.

The percentage ownership information in the table below is based on 36,154,617 shares of common stock outstanding as of April 19, 2024.

Information with respect to beneficial ownership provided in the table below is based upon information supplied by officers, directors and principal shareholders and Schedules 13D and 13G and Form 4 filed with the SEC. We have determined beneficial ownership in accordance with the rules of the SEC. These rules generally attribute beneficial ownership of securities to persons who possess sole or shared voting power or investment power with respect to those securities. In addition, the rules include shares of common stock issuable pursuant to the exercise of stock options or warrants that are either immediately exercisable or exercisable on or before June 18, 2024, which is 60 days after April 19, 2024. These shares are deemed to be outstanding and beneficially owned by the person holding those options or warrants for the purpose of computing the percentage ownership of that person, but they are not treated as outstanding for the purpose of computing the percentage ownership of any other person. Unless otherwise indicated, the persons or entities identified in this table have sole voting and investment power with respect to all shares shown as beneficially owned by them, subject to applicable community property laws.

Base Salary

The base salaries of the named executive officers in 2023, as applicable, were generally determined and approved by the Board of Directors, based on the recommendation of the Compensation Committee.

•

Dr. Birx’s annual base salary for 2023 was $525,000.

•

Dr. Pastagia’s annual base salary for 2023 was $ 456,800.

•

Mr. Rychlik’s annual base salary for 2023 was $290,000.

•

Dr. Varnum’s annual base salary was $ 544,690 for the period of January 1, 2023 through July 10, 2023. Dr. Varnum entered into a separation and release agreement on July 14, 2023 under which he is entitled to continuation of his base salary for 12 months following separation from service, as described in the below section entitled “Payments and Benefits upon Termination or Change in Control.”

•

Ms. Butler’s annual base salary was $300,080 for the period January 1, 2023 through May 1, 2023. Ms. Butler entered into a separation and release agreement on May 1, 2023 under which she is entitled to continuation of her base salary for six months following separation from service, as described in the below section entitled “Payments and Benefits upon Termination or Change in Control.”

Annual Bonus

In addition to base salaries, the named executive officers are eligible to receive annual performance-based cash bonuses, which are designed to provide appropriate incentives to our executives to achieve defined annual corporate goals and to reward our executives for individual achievement towards these goals. The performance-based bonus generally is based on the extent to which we achieved the specified corporate goals that our board of directors or Compensation Committee established. After the end of the year, the board of directors and/or Compensation Committee review our performance against the established corporate goals and approve the extent to which we achieved such goals.

Under the terms of her employment agreement described below, Dr. Birx was eligible to receive an annual performance-based bonus for 2023 equal to, at target, 50% of her annual salary based on our achievement of certain performance goals, pro-rated to reflect the number of days she was employed in 2023. Under the terms of her employment agreement described below, Dr. Pastagia was eligible to receive an annual performance-based bonus for 2023 equal to, at target, 35% of her annual salary based on our achievement of certain performance goals. Under the terms of his employment agreement described below, Mr. Rychlik was eligible to receive an annual performance-based bonus for 2023 equal to, at target, 30% of his annual salary based on our achievement of certain performance goals.

The annual performance-based bonus opportunities are based entirely on the extent to which we achieved corporate goals relating to capital raising, partner and grant funding and progress with clinical development and manufacturing for the fiscal year ending December 31, 2023. The corporate goals were established so that target attainment is not assured. Instead, our executives are required to demonstrate significant effort, dedication, and achievement to attain payment for performance at target or above.

In December 2023, the Compensation Committee reviewed performance results against the corporate goals and recommended that performance-based bonuses not be paid out for 2023. Dr. Varnum and Ms. Butler separated from service on July 10, 2023 and May 1, 2023 respectively, and pursuant to their separation and release agreements, neither was eligible to receive a 2023 annual bonus.

Equity-Based Awards

Our equity-based incentive awards were designed to align our interests with those of our employees and consultants, including the named executive officers. Our board of directors or our Compensation Committee approve equity grants. Vesting of equity awards was generally tied to continuous service and serves as an additional retention measure. Our executives may have been awarded an initial new hire grant upon commencement of service and have received additional grants, as the board of directors or Compensation Committee determined appropriate, in order to incentivize and/or reward such executives.

We historically have granted stock options to the named executive officers under our equity incentive plans. In December 2023, we granted restricted stock units to Dr. Birx. Please see “Outstanding Equity Awards at Fiscal Year End” below.

Equity Incentive Plans

2016 Equity Incentive Plan

The Company’s 2016 Equity Incentive Plan (the “2016 Plan”) was approved by our board of directors in April 2016 and subsequently approved by the shareholders in June 2016, and was most recently amended and restated effective as of May 8, 2019. We continue to grant awards under the 2016 Plan. The plan provides for the issuance of incentive awards in the form of non-qualified and incentive stock options, stock appreciation rights, restricted stock awards, restricted stock unit awards and performance-based stock awards. The awards may be granted by our board of directors to employees, including officers, non-employee directors and consultants who provide services to us or to a subsidiary of ours.

Employee Stock Purchase Plan

Additional long-term equity incentives are provided through the employee stock purchase plan (“ESPP”), which became effective in connection with our 2016 Annual Meeting of Shareholders in

May 2016 and which we continue to use pursuant to the terms described herein. The ESPP is intended to qualify as an “employee stock purchase plan” within the meaning of Section 423 of the Internal Revenue Code. Our board of directors has delegated its authority to administer the ESPP to our Compensation Committee. Under the ESPP, all of our regular employees (including the named executive officers) may participate and may contribute, normally through payroll deductions, up to 15% of their earnings for the purchase of our common stock. The ESPP is implemented through a series of offerings of purchase rights to eligible employees. Under the ESPP, we may specify offerings with a duration of not more than 27 months and may specify shorter purchase periods within each offering. Each offering will have one or more purchase dates on which our common stock will be purchased for employees participating in the offering. Unless otherwise determined by our Compensation Committee, shares are purchased for accounts of employees participating in the ESPP at a price per share equal to the lower of (a) 85% of the fair market value of our common stock on the first date of an offering or (b) 85% of the fair market value of our common stock on the date of purchase.

In 2023, the chair of our Board of Directors received an annual cash retainer of $70,000 and each other non-employee director received an annual cash retainer of $40,000. For the Audit Committee, the committee chair received an additional annual cash retainer of $17,000 and each member received an additional annual cash retainer of $8,000. For the Compensation Committee, the committee chair received an additional annual cash retainer of $12,000 and each member received an additional annual cash retainer of

$6,000. For the Nominating and Corporate Governance Committee, the committee chair received an additional annual cash retainer of $8,000 and each member received an additional annual cash retainer of $4,000. For the Special Committee, the committee chair received an additional annual cash retainer of $10,000 and each member received an additional annual cash retainer of $5,000.

In addition to the cash fees, in December 2023, each non-employee director was granted an option to purchase 10,461 shares of our common stock that is subject to vesting based on the director’s continuous service as of immediately prior to our 2024 Annual Meeting. Subsequent to the grant, it was discovered that an inadvertent calculation error resulted in each non-employee director receiving substantially fewer options than was intended to be granted in respect of services during 2023. To rectify this error, each non-employee director was granted a make-whole option to purchase an additional 39,666 shares of our common stock in March 2024 that is also subject to vesting based on the director’s continuous service as of immediately prior to our 2024 Annual Meeting. However, given the SEC disclosure rules, the amount reflected in the “Option Award” column in the “Director Compensation Table” below only reflects the options granted in 2023, and the make-whole option granted in 2024 will appear on the Director Compensation Table in next year’s proxy statement. As a result, the number reflected in the “Director Compensation Table” below understates the fair value of the equity awards granted in respect of service during 2023 for each non-employee director by approximately $98,674.

Limitation of Liability and Indemnification

Sections 23B.08.510 and 23B.08.570 of the Washington Business Corporation Act authorize Washington corporations to indemnify directors and officers under certain circumstances against expenses (including legal expenses) and liabilities incurred in legal proceedings in which they are involved by reason of being a

director or officer, as applicable. Section 23B.08.560 of the Washington Business Corporation Act authorizes a corporation, if authorized by its articles of incorporation or by a provision in the corporation’s bylaws approved by its shareholders, to indemnify or agree to indemnify a director made a party to a proceeding, or obligate itself to advance or reimburse expenses incurred in a proceeding, without regard to the limitations imposed by Sections 23B.08.510 through 23B.08.550; provided that no such indemnity shall indemnify any director from or on account of (a) acts or omissions of the director finally adjudged to be intentional misconduct or a knowing violation of law, (b) conduct of the director finally adjudged to be in violation of Section 23B.08.310 of the Washington Business Corporation Act (which relates to unlawful distributions) or (c) any transaction with respect to which it was finally adjudged that such director personally received a benefit in money, property or services to which the director was not legally entitled.

Article 11 of our articles of incorporation provides that, to the fullest extent that the Washington Business Corporation Act permits the limitation or elimination of the liability of a director, a director shall not be liable to us or our shareholders for monetary damages for conduct as a director. Section 10 of our bylaws requires us to indemnify every present or former director or officer against expenses, liabilities and losses incurred in connection with serving as a director or officer, as applicable, and to advance expenses of such director or officer incurred in defending any proceeding covered by the indemnity; provided, however, that any indemnity is in accordance with Washington law and does not include indemnification of intentional misconduct, knowing violation of law, or other violations of Washington law, including receipt of benefits in which a director of officer is not entitled.

We maintain a policy of directors’ and officers’ liability insurance that insures the directors and officers against the cost of defense, settlement or payment of a judgment under certain circumstances. We have also entered into indemnification agreements with our executive officers and directors that provide for the indemnification of directors and executive officers to the fullest extent permitted by the Washington Business Corporation Act against expenses reasonably incurred by such persons in any threatened, pending or completed action, suit, investigation or proceeding in connection with their service as (i) a director or officer of us or (ii) a director, officer, employee or agent of another corporation or of a partnership, joint venture, trust or other enterprise, including service with respect to employee benefit plans, at our request. In addition, we are obligated to advance expenses pursuant to the indemnification agreements under certain circumstances, and the agreements also provide for procedural protections, including a determination by a reviewing party as to whether the indemnitee is permitted to be indemnified under applicable law.

The limitation of liability and indemnification provisions in our articles of incorporation and bylaws may discourage shareholders from bringing a lawsuit against directors for breach of their fiduciary duties. They may also reduce the likelihood of derivative litigation against directors and officers, even though an action, if successful, might benefit us and our shareholders. A shareholder’s investment may be harmed to the extent we pay the costs of settlement and damage awards against directors and officers pursuant to these indemnification provisions.

We believe that these provisions in our articles of incorporation and bylaws and our indemnification agreements are necessary to attract and retain qualified persons as directors and officers.

At present, there is no pending litigation or proceeding involving any of our directors or executive officers as to which indemnification is required or permitted, and we are not aware of any threatened litigation or proceeding that may result in a claim for indemnification.

TRANSACTIONS WITH RELATED PERSONS

We have adopted a written related-person transactions policy that sets forth our policies and procedures regarding the identification, review, consideration and oversight of “related-person transactions.” For purposes of our policy only, a “related-person transaction” is any transaction, arrangement or relationship (or any series of similar transactions, arrangements or relationships) occurring since the beginning of the Company’s last fiscal year, or any currently proposed transaction, in which we and any “related person” (defined below) are participants involving an amount that exceeds $120,000 (or such lower threshold as may be applicable to us from time to time pursuant to the rules and regulations of the SEC or the NYSE American exchange), and in which any “related person” had or will have a direct or indirect material interest.

Transactions involving compensation for services provided to us by an employee, consultant or director are not considered related-person transactions under this policy. A “related person” is any person who is, or at any time since the beginning of our last fiscal year, was, an executive officer, director or director nominee, any holder of more than 5% of our common stock, any of the foregoing’s immediate family members and any entity owned or controlled by any such persons.

Under the policy, where a transaction has been identified as a related-person transaction, management must present information regarding the proposed related-person transaction to our Audit Committee (or, where review by our Audit Committee would be inappropriate, to another independent body of our Board of Directors) for approval. The presentation must include a description of, among other things, the material facts, the direct and indirect interests of the related persons, the benefits of the transaction to us and whether any alternative sources for comparable services or products are available. To identify related-person transactions in advance, we rely on information supplied by our executive officers, directors, director nominees and certain significant shareholders. In considering related-person transactions, our Audit Committee or other independent body of our Board of Directors takes into account the relevant available facts and circumstances including, but not limited to:

•

the risks, costs and benefits to us;

•

the impact on a director’s independence in the event the related person is a director, immediate family member of a director or an entity with which a director is affiliated;

•

the terms of the transaction; and

•

the terms available to or from, as the case may be, unrelated third parties.

In the event a director has an interest in the proposed transaction, the director must recuse himself or herself from the deliberation and approval.

Certain Related-Person Transactions

Described below are any transactions occurring since January 1, 2023, and any currently proposed transactions, to which C3J or Armata was a party and in which:

•

The amounts involved exceeded or will exceed the lesser of (i) $120,000 and (ii) 1% of the average of the respective company’s total assets at year-end for the last two completed fiscal years; and

•

A director, director nominee, executive officer, holder of more than 5% of the outstanding capital stock of the respective company, or any member of such person’s immediate family had or will have a direct or indirect material interest.

Financing Transactions

January 2023 Credit Agreement

On January 10, 2023, the Company entered into, as borrower, a secured convertible credit and security agreement (the “January 2023 Credit Agreement”) with Innoviva Strategic Opportunities LLC (“Innoviva SO”). The January 2023 Credit Agreement provides for a secured term loan facility in an aggregate amount of $30 million (the “January 2023 Loan”) at an interest rate of 8.0% per annum, and has a maturity date of January 10, 2024. Repayment of the January 2023 Loan is required to be guaranteed by our domestic

subsidiaries and foreign material subsidiaries, and the January 2023 Loan is secured by substantially all of our assets and the subsidiary guarantors.

The January 2023 Credit Agreement provides that if a Qualified Financing, as defined in the January 2023 Credit Agreement, occurs, the outstanding principal amount of, and all accrued and unpaid interest on, the January 2023 Loan shall be converted into shares of our common stock at a price per share equal to a 15.0% discount to the lowest price per share for the Company’s common stock paid by investors in a Qualified Financing (which price paid by investors in a Qualified Financing may not be less than a 15.0% discount to the closing price of our common stock immediately prior to the consummation of a Qualified Financing event). The January 2023 Credit Agreement also requires the Company to file a registration statement for the resale of all securities issued to the lender in connection with any conversion under the January 2023 Credit Agreement, which the Company filed on February 13, 2023. The U.S. Securities and Exchange Commission (the “SEC”) declared the registration statement effective as of 4 p.m. on April 6, 2023, whereupon any outstanding January 2023 Loan amount, including all accrued and unpaid interest thereon, may be converted at the lender’s option, into shares of our common stock at a price per share equal to the greater of book value or market value per share of our common stock on the date immediately preceding the effective date of the January 2023 Credit Agreement, which is $1.52 (as may be appropriately adjusted for any stock split, combination or similar act).

January 2023 Registration Rights Agreement

Pursuant to the Registration Rights Agreement with the selling shareholder, we agreed to prepare and file with the SEC a registration statement on Form S-3, of which this prospectus forms a part, that permits the resale of the Shares and, subject to certain exceptions, to use commercially reasonable efforts to keep the registration statement of which this prospectus forms a part effective under the Securities Act until (i) all shares registered by this registration statement have been sold, transferred or otherwise disposed of by the selling shareholder, (ii) the shares are sold, transferred or otherwise disposed of pursuant to Rule 144 of the Securities Act, (iii) the shares cease to be outstanding, or (iv) the shares have become eligible for sale by the selling shareholder pursuant to Rule 144 of the Securities Act without any restriction on the volume or manner of such sale and all restrictive legends and stop transfer instructions have been removed with respect to all book entries representing the shares.

July 2023 Credit Agreement

On July 10, 2023, the Company entered into, as borrower, a credit and security agreement (the “July 2023 Credit Agreement”) with Innoviva SO. The Credit Agreement provides for a secured term loan facility in an aggregate amount of $25 million (the “July 2023 Loan”) at an interest rate of 14.0% per annum, and has a maturity date of January 10, 2025. Repayment of the July 2023 Loan is guaranteed by the Company’s domestic subsidiaries, and the July 2023 Loan is secured by substantially all of the assets of the Company and the subsidiary guarantors.

Concurrently with the execution of the July 2023 Credit Agreement, the Company entered into an amendment to the January 2023 Credit Agreement, pursuant to which the parties agreed to, among other things, extend the maturity date from January 10, 2024 to January 10, 2025. In addition, the Company concurrently entered into an amendment to the February 2022 Voting Agreement, to extend the expiration date to the earlier of the fifth anniversary of the effective date, or February 9, 2027, and the date of receipt of approval by the U.S. Food and Drug Administration of any of the product candidates of the Company for marketing and commercial distribution.

2024 Credit Agreement

On March 4, 2024, the Company entered into a credit and security agreement (the “2024 Credit Agreement”) for a loan in an aggregate amount of $35.0 million with Innoviva SO. The 2024 loan bears interest at an annual rate of 14% and matures on June 4, 2025. Principal and accrued interest are payable at maturity. Repayment of the loan is guaranteed by our domestic subsidiaries, and the loan is secured by substantially all of our assets. Concurrently with the execution of the 2024 loan, the Company amended certain provisions of the convertible loan and July 2023 Credit Agreement to, among other things, conform certain terms relating to permitted indebtedness and permitted liens.

Change in Control and Severance Benefits Arrangements

We have entered into certain change in control and severance benefits arrangements with our officers, as more fully described in the section above entitled “Executive Compensation.”

Director and Executive Officer Compensation

The compensation of our directors and named executive officers, including employment agreements and other compensatory arrangements with executive officers and stock option grants to executive officers and directors, is more fully described in the section above entitled “Executive Compensation.”

Indemnification Agreements

We have entered, and intend to continue to enter, into separate indemnification agreements with each of our directors and executive officers, as described in the section above entitled “Executive Compensation — Limitation of Liability and Indemnification.” In addition, the Merger Agreement provided that, for a period of six years following the effective time of the Merger, we will indemnify and hold harmless each person who is, has been, or who became prior to the effective time of the Merger, a director, officer, fiduciary or agent of us and our subsidiaries or C3J, respectively, against all claims, losses, liabilities, damages, judgments, fines and reasonable fees, costs and expenses, including attorneys’ fees and disbursements, incurred in connection with any claim, action, suit, proceeding or investigation, whether civil, criminal, administrative or investigative, arising out of or pertaining to the fact that such person is or was a director, officer, fiduciary or agent of C3J or us or any of its or our respective subsidiaries, whether asserted or claimed prior to, at or after the effective time, in each case, to the fullest extent permitted under applicable law. Each such person will be entitled to advancement of expenses incurred in the defense of any such claim, action, suit, proceeding or investigation from us.

The Merger Agreement also provided that the provisions relating to the indemnification, advancement of expenses and exculpation of our present and former directors and officers set forth in our articles of incorporation and bylaws will not be amended, repealed or otherwise modified for a period of six years from the effective time of the Merger in any manner that would adversely affect the rights of individuals who, at the effective time of the Merger, were our officers or directors. The Merger Agreement required that, after the closing of the Merger, our articles of incorporation and bylaws were to contain provisions at least as favorable as the provisions relating to the indemnification, advancement of expenses and exculpation of present and former directors and officers set forth in our articles of incorporation and bylaws prior to the Merger.

Prior to the effective time of the Merger, we secured and prepaid, at C3J’s expense, a six year “tail policy” on our then-existing directors’ and officers’ liability insurance policy.

DELINQUENT SECTION 16(A) REPORTS

Section 16(a) of the Exchange Act requires our directors, executive officers and any persons beneficially holding more than 10% of our common stock to report their initial ownership of our common stock and any subsequent changes in that ownership to the SEC. Our executive officers, directors and greater than 10% shareholders are required by SEC regulation to furnish us with copies of all Section 16(a) forms they file.

Specific due dates for these reports have been established and we are required to identify those persons who failed to timely file these reports. To our knowledge, based solely on a review of the copies of such reports furnished to us and written representations from our directors and officers that no other reports were required, during the fiscal year ended December 31, 2023, all of our directors, officers and greater than 10% shareholders complied with the Section 16(a) filing requirements.

We have adopted a code of ethics for directors, officers (including our principal executive officer, principal financial officer, principal accounting officer and controller) and employees, known as the Code of Business Conduct and Ethics. The Code of Business Conduct and Ethics is available on our website at https://investor.armatapharma.com/corporate-governance. We will promptly disclose on our website (i) the nature of any amendment to the policy that applies to our principal executive officer, principal financial officer, principal accounting officer or controller, or persons performing similar functions and (ii) the nature of any waiver, including an implicit waiver, from a provision of the policy that is granted to one of these specified individuals that is required to be disclosed pursuant to SEC rules and regulations, the name of such person who is granted the waiver and the date of the waiver.

HOUSEHOLDING OF PROXY MATERIALS

The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for annual meeting materials with respect to two or more shareholders sharing the same address by delivering a single set of annual meeting materials addressed to those shareholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for shareholders and cost savings for companies.

This year, a number of brokers with account holders who are Armata shareholders will be “householding” the Company’s proxy materials. That means that only one copy of the Proxy Materials or this Proxy Statement and annual report will be delivered to multiple shareholders sharing an address, unless contrary instructions have been received from the affected shareholders. Once you have received notice from your broker that they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. If, at any time, you no longer wish to participate in “householding” and would prefer to receive a separate set of the applicable annual meeting materials, either for this annual meeting or in the future, please notify your broker or Armata. Direct your written request to Armata Pharmaceuticals, Inc., Attention: Investor Relations, 5005 McConnell Avenue, Los Angeles, California 90066 or contact Joyce Allaire at (212) 915-2569. If so requested, a separate copy of the Proxy Statement or annual report will be delivered to you promptly and without charge. Shareholders who currently receive multiple copies of the applicable annual meeting materials at their addresses and would like to request “householding” of their communications should contact their brokers.

OTHER MATTERS

The Board of Directors knows of no other matters that will be presented for consideration at the meeting. If any other matters are properly brought before the meeting, it is the intention of the persons named in the accompanying proxy to vote on such matters in accordance with their best judgment.
