The Notice will identify the website where the proxy materials will be made available; the date, the time and location of the Annual Meeting; the matters to be acted upon at the meeting and our board of directors’ recommendations with regard to each matter; a toll-free telephone number, an e-mail address, and a website where stockholders can request a paper or e-mail copy of the Proxy Statement; our Annual Report on Form 10-K for the year ended December 31, 2024, or our Annual Report, and a form of proxy relating to the Annual Meeting; information on how to access the form of proxy; and information on how to participate in the meeting and vote in person.

QUESTIONS AND ANSWERS ABOUT THE MEETING


Q:	What is the purpose of the meeting?


A:	At the meeting, stockholders will act upon the proposals described in this Proxy Statement. In addition, following the formal portion of the meeting, management will be available to respond to questions from stockholders.


Q:	What proposals are scheduled to be voted on at the meeting?


A:	Stockholders will be asked to vote on the following three proposals at the meeting:

to elect Mary Ann Gray, Ph.D., Susan Moran, M.D., M.S.C.E. and Lawrence Steinman, M.D. as Class II directors to serve for a term of three years or until his or her successor is duly elected and qualified or until his or her earlier death, resignation, disqualification or removal;

to ratify the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025; and

to approve, by a non-binding advisory vote, the executive compensation of our named executive officers.

- 1 -


Q:	Could matters other than Proposals One, Two or Three be decided at the meeting?


A:	Our bylaws require that we receive advance notice of any proposal to be brought before the meeting by stockholders of BioAtla, and we have not received notice of any such proposals. If any other matter were to come before the meeting, the proxy holders appointed by our board of directors will have the discretion to vote on those matters for you.


Q:	How does the board of directors recommend I vote on these proposals?


A:	Our board of directors recommends that you vote your shares:

•

“FOR” each of the nominees to the board of directors (Proposal One);

•

“FOR” the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025 (Proposal Two); and

•

“FOR” the executive compensation of our named executive officers as disclosed in this Proxy Statement (Proposal Three).


Q:	Who may vote at the Annual Meeting?


A:	Holders of record of our common stock as of the close of business on April 21, 2025, or the Record Date, are entitled to receive notice of, to attend and participate, and to vote at the Annual Meeting. At the close of business on the Record Date, there were 58,415,955 shares of our common stock outstanding and entitled to vote.

Stockholder of Record: Shares Registered in Your Name

If your shares are registered directly in your name with our transfer agent, Pacific Stock Transfer Company, you are considered the stockholder of record with respect to those shares, and the Notice or these proxy materials were sent directly to you by BioAtla.

Beneficial Owner of Shares Held in Street Name: Shares Registered in the Name of a Broker or Nominee

If your shares are held in an account at a brokerage firm, bank, broker-dealer, or other similar organization, then you are the “beneficial owner” of shares held in “street name,” and the Notice or these proxy materials were forwarded to you by that organization. The organization holding your account is considered the stockholder of record for purposes of voting at the Annual Meeting. As a beneficial owner, you have the right to instruct that organization on how to vote the shares held in your account. In most instances, you can do this over the internet, or if you have received or requested a hard copy of the Proxy Statement and accompanying voting instruction form, you may mark, sign, date and mail your voting instruction form using the envelope your broker, bank or other nominee provides. The materials that were sent to you have specific instructions for how to submit your vote and the deadline for doing so. If you would like to revoke your proxy, you must follow the broker, bank or other nominee’s instructions on how to do so.

Because you are not the stockholder of record, you are required to obtain a valid proxy from the organization that holds your shares giving you the right to vote the shares at the Annual Meeting.

- 2 -


Q:	How do I vote?


A.	You may vote by mail or follow any alternative voting procedure (such as telephone or internet voting) described on your proxy card. To use an alternative voting procedure, follow the instructions on each Notice and/or proxy card that you receive. The procedures for voting are as follows:

Stockholder of Record: Shares Registered in Your Name

If you are a stockholder of record, you may:

•

vote by telephone or through the internet—in order to do so, please follow the instructions shown on your Notice or proxy card;

•

vote by mail—if you request or receive a paper proxy card and voting instructions by mail, simply complete, sign and date the enclosed proxy card and return it before the meeting in the pre-paid envelope provided; or

•

vote in person—you may virtually attend and participate in the Annual Meeting online at www.proxydocs.com/BCAB and vote your shares electronically before the polls close during the Annual Meeting.

Votes submitted by telephone or through the internet must be received prior to the start of the meeting. Submitting your proxy, whether by telephone, through the internet or by mail if you request or received a paper proxy card, will not affect your right to vote in person should you decide to attend and participate in the meeting virtually.

Beneficial Owner: Shares Registered in the Name of a Broker or Other Nominee

If you are not the stockholder of record, please refer to the voting instructions provided by your nominee to direct it how to vote your shares. Your vote is important. To ensure that your vote is counted, complete and mail the voting instruction card provided by your brokerage firm, bank, or other nominee as directed by your nominee. To electronically vote in person at the meeting online, you may be required to obtain a legal proxy from your nominee. Follow the instructions from your nominee included with our proxy materials or contact your nominee to request a proxy form. You must also register in advance to attend and participate in the meeting www.proxydocs.com/BCAB.

Your vote is important. Whether or not you plan to participate in the Annual Meeting, we urge you to vote by proxy to ensure that your vote is counted.


Q:	How do I vote by internet or telephone?

     A.

     If you wish to vote by internet or telephone, you may do so by following the voting instructions included on your Notice or proxy card. Please have each Notice or proxy card you received in hand when you vote over the internet or by telephone as you will need information specified therein to submit your vote. The giving of such a telephonic or internet proxy will not affect your right to vote in person (as detailed above) should you decide to attend the meeting.

The telephone and internet voting procedures are designed to authenticate stockholders’ identities, to allow stockholders to give their voting instructions and to confirm that stockholders’ instructions have been recorded properly.

- 3 -


Q:	What shares can I vote?

     A:

     Each share of BioAtla common stock issued and outstanding as of the close of business on April 21, 2025 is entitled to vote on all items being voted on at the meeting. You may vote all shares owned by you as of April 21, 2025, including (1) shares held directly in your name as the stockholder of record, and (2) shares held for you as the beneficial owner in street name through a broker, bank, trustee, or other nominee.


Q:	How many votes am I entitled to per share?


A:	Each holder of shares of common stock is entitled to one vote for each share of common stock held as of April 21, 2025.


Q:	What is the quorum requirement for the meeting?

     A:

     The holders of a majority of the voting power of the shares of our common stock entitled to vote at the Annual Meeting as of the Record Date must be present in person or represented by proxy at the Annual Meeting in order to hold the Annual Meeting and conduct business. This presence is called a quorum. Your shares are counted as present at the Annual Meeting if you are present and vote in person at the Annual Meeting or if you have properly submitted a proxy.


Q:	How are abstentions and broker non-votes treated?


A:	Abstentions (i.e. shares present at the Annual Meeting and marked “abstain”) are deemed to be shares presented or represented by proxy and entitled to vote, and are counted for purposes of determining whether a quorum is present. However, abstentions are not counted as a vote either for or against a proposal, and have no effect on the outcome of the matters voted upon.

A broker non-vote occurs when the beneficial owner of shares fails to provide the broker, bank or other nominee that holds the shares with specific instructions on how to vote on any “non-routine” matters brought to a vote at the stockholders meeting. In this situation, the broker, bank or other nominee will not vote on the “non-routine” matter. Broker non-votes are counted for purposes of determining whether a quorum is present and have no effect on the outcome of the matters voted upon.

Note that if you are a beneficial holder, brokers and other nominees will be entitled to vote your shares on “routine” matters without instructions from you. The only proposal that would be considered “routine” in such event is the proposal for the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the fiscal year ending December 31, 2025 (Proposal Two). A broker or other nominee will not be entitled to vote your shares on any “non-routine” matters, absent instructions from you. “Non-routine” matters include all proposals other than Proposal Two, including Proposals One and Three. Accordingly, we encourage you to provide voting instructions to your broker or other nominee whether or not you plan to attend the meeting.


Q:	How are “withhold” votes treated?

     A:

     For the election of directors (Proposal One), votes may be cast “FOR” or “WITHHOLD” for each nominee. Votes that are withheld will be excluded entirely from the vote and will have no effect. Directors shall be elected by a plurality of the votes of the shares present in person or represented by proxy at the meeting and entitled to vote on the election of directors with the stockholders voting together as a single class. As a result, if you withhold your authority to vote for any nominee, your vote will not count for or against the nominee.

- 4 -


Q:	What is the vote required for each proposal?


A:	The votes required to approve each proposal are as follows:

•

Proposal One: Each director shall be elected by a plurality of the votes properly cast on the election of directors, meaning that the individuals nominated for election to our board of directors at the Annual Meeting receiving the highest number of “FOR” votes will be elected.

•

Proposal Two: Approval will be obtained if the number of votes cast “FOR” the proposal at the Annual Meeting exceeds the number of votes “AGAINST” the proposal.

•

Proposal Three: Approval will be obtained if the number of votes cast “FOR” the proposal at the Annual Meeting exceeds the number of votes “AGAINST” the proposal. Because the vote is advisory, it will not be binding upon our board of directors. However, the compensation committee of our board of directors will take into account the outcome of the vote when considering the future executive compensation of our Named Executive Officers as disclosed in the Proxy Statement.


Q:	If I submit a proxy, how will it be voted?

     A:

     When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, the shares will be voted in accordance with the recommendations of our board of directors as described above. If any matters not described in the Proxy Statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the Annual Meeting is postponed or adjourned, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy instructions, as described below under “Can I change my vote or revoke my proxy?”


Q:	What should I do if I get more than one proxy or voting instruction card?

     A:

     Stockholders may receive more than one set of voting materials, including multiple copies of the proxy materials and multiple Notices, proxy cards or voting instruction cards. For example, stockholders who hold shares in more than one brokerage account may receive separate sets of proxy materials or one Notice for each brokerage account in which shares are held. Stockholders of record whose shares are registered in more than one name will receive more than one set of proxy materials. You should vote in accordance with all of the proxy cards and voting instruction cards you receive relating to our Annual Meeting to ensure that all of your shares are voted and counted.


Q:	Can I change my vote or revoke my proxy?


A:	You may change your vote or revoke your proxy at any time prior to the taking of the vote or the polls closing at the Annual Meeting.

If you are the stockholder of record, you may change your vote by:

•

granting a new proxy bearing a later date (which automatically revokes the earlier proxy) using any of the methods described above (and until the applicable deadline for each method);

•

providing a written notice of revocation to BioAtla’s Corporate Secretary at BioAtla, Inc., 11085 Torreyana Road, San Diego, California 92121, prior to your shares being voted, or

•

participating in the Annual Meeting and voting electronically online at www.proxydocs.com/BCAB. Participation alone at the Annual Meeting will not cause your previously granted proxy to be revoked unless you specifically vote during the meeting online at www.proxydocs.com/BCAB.

Please note, however, that if your shares are held of record by a broker, bank or other nominee and you wish to revoke a proxy, you must contact that firm to revoke any prior voting instructions.

- 5 -


Q:	How can I attend the Annual Meeting in person?

     A:

     There is no physical location for the Annual Meeting. You are invited to attend the Annual Meeting by participating online if you are a stockholder of record or a street name stockholder as of April 21, 2025, the Record Date. See, “How can I participate in the Annual Meeting?” below for more details. Please be aware that participating in the Annual Meeting will not, by itself, revoke a proxy. See, “Can I change my vote or revoke my proxy?” above for more details.


Q:	How can I participate in the Annual Meeting?

     A:

     The Annual Meeting will be a completely virtual meeting of stockholders, which will be conducted via live webcast. You will be able to attend and participate in the Annual Meeting online and submit your questions during the Annual Meeting by visiting www.proxydocs.com/BCAB and registering in advance. You will also be able to vote your shares electronically at the Annual Meeting by following the instructions you receive via email.

The meeting webcast will begin promptly at 8:00 a.m. Pacific Time. We encourage you to access the meeting prior to the start time. Online check-in will begin at 7:45 a.m., Pacific Time, and you should allow ample time to check your audio/video connections and settings. We plan to have a webcast replay which will be posted to the Investors – Events & Presentations section of our website, which is located at www.bioatla.com.


Q:	Can I submit questions prior to the meeting?


A:	No, you can only submit questions during the meeting.


Q:	What if during the check-in time or during the meeting I have technical difficulties or trouble accessing the virtual meeting website?


A:	If you encounter any technical difficulties accessing the virtual meeting during the check-in or meeting time, please call the toll-free technical support line you receive in your email prior to the start of the meeting.


Q.	How can I get electronic access to the proxy materials?


A:	The Notice will provide you with instructions regarding how to:

•

view our proxy materials for the meeting through the internet; and

•

instruct us to send our future proxy materials to you electronically by email.

If you choose to receive future proxy materials by email, you will receive an email next year with instructions containing a link to those materials and a link to the proxy voting site. Your election to receive proxy materials by email will remain in effect until you terminate it.


Q:	Is there a list of stockholders entitled to vote at the Annual Meeting?

     A:

     The names of stockholders of record entitled to vote will be available for inspection by stockholders of record for a period of ten (10) days ending on the day before the date of the Annual Meeting. If you are a stockholder of record and want to inspect the stockholder list, please send a written request to our Corporate Secretary at investors@bioatla.com to arrange for inspection of the list at our corporate headquarters, 11085 Torreyana Road, San Diego, California 92121.

- 6 -


Q:	Who will tabulate the votes?


A:	A representative of Mediant Communications, Inc. will serve as the Inspector of Elections and will tabulate the votes at the Annual Meeting.


Q:	Where can I find the voting results of the Annual Meeting?


A:	We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K that we will file with the SEC within four business days after the Annual Meeting.


Q:	I share an address with another stockholder, and we received only one paper copy of the proxy materials. How may I obtain an additional copy of the proxy materials?


A:	The SEC has adopted rules that permit companies and intermediaries (e.g., brokers) to satisfy the delivery requirements for proxy statements and annual reports with respect to two or more stockholders sharing the same address by delivering a single proxy statement addressed to those stockholders. This process is commonly referred to as “householding.”

Brokers with account holders who are BioAtla stockholders may be householding our proxy materials. A single set of proxy materials may be delivered to multiple stockholders sharing an address unless contrary instructions have been received from the affected stockholders. Once you have received notice from your broker that it will be householding communications to your address, householding will continue until you are notified otherwise or until you notify your broker or BioAtla that you no longer wish to participate in householding.

If, at any time, you no longer wish to participate in householding and would prefer to receive a separate proxy statement and annual report, you may (1) notify your broker, (2) direct your written request to: Investor Relations, BioAtla, Inc., 11085 Torreyana Road, San Diego, California 92121 or (3) contact our Investor Relations department by email at investors@bioatla.com or by telephone at (858) 558-0708. Stockholders who currently receive multiple copies of the proxy statement or annual report at their address and would like to request householding of their communications should contact their broker. In addition, we will promptly deliver, upon written or oral request to the address or telephone number above, a separate copy of the annual report and proxy statement to a stockholder at a shared address to which a single copy of the documents was delivered.


Q:	What if I have questions about my BioAtla shares or need to change my mailing address?


A:	You may contact our transfer agent, Pacific Stock Transfer Company, by telephone at (702) 361-3033, by email at info@pacificstocktransfer.com or by U.S. mail at 6725 Via Austi Pkwy, Ste. 300, Las Vegas, Nevada, 89119, if you have questions about your BioAtla shares or need to change your mailing address.


Q:	Who is soliciting my proxy and paying for the expense of solicitation?

     A:

     The proxy for the Annual Meeting is being solicited on behalf of our board of directors. We will pay the cost of preparing, assembling, printing, mailing and distributing these proxy materials and soliciting votes. We may, on request, reimburse brokerage firms and other nominees for their expenses in forwarding proxy materials to beneficial owners. In addition to soliciting proxies by mail, we expect that our directors, officers and employees may solicit proxies in person or by telephone or facsimile. None of these individuals will receive any additional or special compensation for doing this, although we may reimburse these individuals for their reasonable out-of-pocket expenses. We do not expect to, but have the option to, retain a proxy solicitor. If you choose to access the proxy materials or vote via the internet or by phone, you are responsible for any internet access or phone charges you may incur.

Q:	What are the requirements to propose actions, including director nominations, to be included in our proxy materials for next year’s annual meeting of stockholders, or our 2026 Annual Meeting, or for consideration at our 2026 Annual Meeting?


A:	Requirements for Stockholder Proposals to be considered for inclusion in our proxy materials for our 2026 Annual Meeting:

Our amended and restated bylaws provide that stockholders may present proposals, including director nominations, for inclusion in our proxy statement by submitting their proposals in writing to the attention of our Corporate Secretary at our principal executive office via the delivery methods specified in our amended and restated bylaws. To be timely and considered for inclusion in our proxy materials, such proposals must comply in all respects with our amended and restated bylaws. Our current principal executive office is located at 11085 Torreyana Road, San Diego, California 92121. The facsimile number and the e-mail address of our Corporate Secretary are (858)558-0709 and cvasquez@bioatla.com. In addition, stockholder proposals must comply with the requirements of Rule 14a-8 under the Securities Exchange Act of 1934, as amended, or the Exchange Act, and related SEC regulations under Rule 14a-8 regarding the inclusion of stockholder proposals in company-sponsored proxy materials. In order to be included in the proxy statement for our 2026 Annual Meeting, stockholder proposals must be received by our Corporate Secretary no later than January 2, 2026, 120 calendar days before the release date of the proxy statement to shareholders for the preceding year’s annual meeting, and must otherwise comply with the requirements of Rule 14a-8 of the Exchange Act.

Requirements for Stockholder Proposals to be presented at our 2026 Annual Meeting:

Our amended and restated bylaws provide that stockholders may present proposals to be considered at an annual meeting by providing timely notice to our Corporate Secretary at our principal executive office. To be timely for our 2026 Annual Meeting, our Corporate Secretary must receive the written notice at our principal executive office:

•

not earlier than the close of business on February 13, 2025, and

•

not later than the close of business on March 15, 2025.

If we hold our 2026 annual meeting of stockholders more than 30 days before or more than 60 days after June 18, 2026 (the one-year anniversary date of the Annual Meeting), then notice of a stockholder proposal that is not intended to be included in our proxy statement must be received by our Corporate Secretary at our principal executive office not later than the close of business on the later of (i) the 90th day prior to such annual meeting, or (ii) the tenth day following the day on which public announcement of the date of such annual meeting is first made.

A stockholder’s notice to the Corporate Secretary must set forth as to each matter the stockholder proposes to bring before the annual meeting the information required by our amended and restated bylaws. If a stockholder who has notified BioAtla of such stockholder’s intention to present a proposal at an annual meeting does not appear to present such stockholder’s proposal at such meeting, BioAtla does not need to present the proposal for vote at such meeting.

In addition, stockholders who intend to solicit proxies in support of director nominees other than those nominees nominated by the Company must also comply with the additional requirements of Rule 14a-19(b) under the Exchange Act.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

We have a strong commitment to good corporate governance practices. These practices provide an important framework within which our board of directors, its committees and our management can pursue our strategic objectives in order to promote the interests of our stockholders.

- 8 -

Corporate Governance Guidelines

Our board of directors has adopted Corporate Governance Guidelines that set forth expectations for directors, director independence standards, board committee structure and functions and other policies for the governance of our company. Our Corporate Governance Guidelines are available without charge on our website, www.bioatla.com, in the website’s “Investors/Governance” section. Our Corporate Governance Guidelines are subject to modification from time to time by our board of directors pursuant to the recommendations of our nominating and corporate governance committee.

Board Leadership Structure and Risk Oversight

Our board of directors is currently chaired by Jay M. Short, Ph.D., who also serves as our Chief Executive Officer. Our board of directors does not have a policy regarding the separation of the roles of Chief Executive Officer and Chairman of the board of directors, as our board of directors believes it is in our best interest to make that determination based on our position and direction and the membership of the board of directors. Our board of directors has determined that having an employee director serve as Chairman is in the best interest of our stockholders at this time because of the efficiencies achieved in having the role of Chief Executive Officer and Chairman combined, and because the detailed knowledge of our day-to-day operations and business that the Chief Executive Officer possesses greatly enhances the decision-making processes of our board of directors as a whole. We have a governance structure in place, including independent directors, designed to ensure the powers and duties of the dual role are handled responsibly. Our Corporate Governance Guidelines provide that if the Chairman of our board of directors is not an independent director, our independent directors will designate one of the independent directors to serve as Lead Independent Director. Because Dr. Jay M. Short is our Chairman and Chief Executive Officer, our board of directors, including the independent directors, has appointed Dr. Lawrence Steinman to serve as our Lead Independent Director. As Lead Independent Director, Dr. Steinman presides over regularly scheduled executive sessions of our independent directors, coordinates activities of the independent directors, and performs such additional duties as our board of directors otherwise determines and delegates.

Although our board of directors does not have a standing risk management committee, it administers this oversight function directly through the board of directors as a whole as well as through its standing committees that address risks inherent in their respective areas of oversight. Our board of directors oversees the management of risks inherent in the operation of our business and the implementation of our business strategies. In connection with its reviews of our operations and corporate functions, our board of directors addresses the primary risks associated with those operations and corporate functions. Areas of focus include economic, operational, financial (accounting, credit, investment, liquidity and tax), competitive, legal, regulatory, cybersecurity, privacy, compliance and reputational, and environmental, social, and governance (“ESG”) risks. In addition, our board of directors reviews the risks associated with our business strategies periodically throughout the year as part of its consideration of undertaking any such business strategies. The risk oversight responsibility of our board of directors and its committees is supported by our management reporting processes, which are designed to provide visibility to our board of directors and to our personnel who are responsible for risk assessment and information about the identification, assessment and management of critical risks, and our management’s risk mitigation strategies.

Each of our board committees also oversees the management of our risks that fall within the committee’s areas of responsibility. In performing this function, each committee has full access to management, as well as the ability to engage advisors. Our Chief Executive Officer and Chief Financial Officer report to the audit committee and are responsible for identifying, evaluating and implementing risk management controls and methodologies to address any identified risks. Our audit committee is responsible for reviewing and discussing our major financial risk exposures and the steps our management has taken to monitor and control these exposures, including guidelines and policies with respect to risk assessment and risk management. The audit committee also monitors compliance with legal and regulatory requirements and assists our board of directors in fulfilling its oversight responsibilities with respect to risk management, including risks related to cybersecurity matters. Our nominating and corporate governance committee assesses risks related to our corporate governance practices, ESG matters, the independence of our board of directors and monitors the effectiveness of our governance guidelines. Our compensation committee assesses and monitors whether any of our compensation policies and programs has the potential to encourage excessive risk-taking.

We believe this division of responsibilities is an effective approach for addressing the risks we face and that our board leadership structure supports this approach.

Board Composition and Diversity

We believe the board is most effective when it embodies a diverse range of views, backgrounds and experience. Diversity is considered in the broadest sense, including, among other attributes, reflecting geography, age, gender, leadership, perspectives, educational background, other board experience and commitments, business and professional achievements, skills and experience in the context of the needs of the board of directors. While the nominating and corporate governance committee does not have a formal policy on diversity with regard to consideration of director nominees, the nominating and corporate governance committee considers diversity in its selection of nominees and endeavors to include women and minority candidates in the qualified pool from which candidates for the board of directors are chosen.

The Board believes that transparency into its composition supports effective governance and informed shareholder engagement. The table below summarizes the self-identified gender and racial/ethnic demographics of our directors. These attributes, alongside each director’s experience and expertise, contribute to the Board’s ability to provide diverse perspectives and independent oversight.

Independence of Directors

The Nasdaq listing rules generally require that a majority of the members of a listed company’s board of directors be independent. In addition, the listing rules generally require that, subject to specified exceptions, each member of a listed company’s audit, compensation and nominating and corporate governance committees be independent.

In addition, audit committee members must also satisfy the independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended, or the Exchange Act. In order to be considered independent for purposes of Rule 10A-3, a member of an audit committee of a listed company may not, other than in such member’s capacity as a member of the audit committee, the board of directors or any other board committee (i) accept, directly or indirectly, any consulting, advisory or other compensatory fee from the listed company or any of its subsidiaries or (ii) be an affiliated person of the listed company or any of its subsidiaries.

Our board of directors conducts an annual review of the independence of our directors. Our board of directors has determined that none of the nominees and members of our board of directors other than Dr. Short and Mr. Smith has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director and that each of our nominees and the current members of our board of directors other than Dr. Short and Mr. Smith is “independent” as that term is defined under the rules of Nasdaq. Our board of directors has also determined that all members of our audit committee, compensation committee and nominating and corporate governance committee are independent and satisfy the relevant SEC and Nasdaq independence requirements for such committees.

Committees of Our Board of Directors

Our board of directors has established an audit committee, a compensation committee and a nominating and corporate governance committee. The composition and responsibilities of each committee are described below. Each of these committees has a written charter approved by our board of directors. Copies of the charters for each committee are available on the Investors/Governance section of our website, which is located at www.bioatla.com. Members serve on these committees until (i) they resign from their respective committee, (ii) they no longer serve as a director or (iii) as otherwise determined by our board of directors.

Audit Committee

Our audit committee is currently composed of Mary Ann Gray, Ph.D., who is the chair of our audit committee, Sylvia McBrinn, and Edward Williams. The composition of our audit committee meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations. Each member of our audit committee is financially literate. In addition, our board of directors has determined that Dr. Gray qualifies as an audit committee financial expert within the meaning of Item 407(d) of Regulation S-K of the Securities Act of 1933, as amended, or the Securities Act. This designation does not impose any duties, obligations or liabilities that are greater than those generally imposed on members of our audit committee and our board of directors.

As more fully described in its charter, our audit committee, has responsibility for, among other things:

•

evaluating the performance, independence and qualifications of our independent auditors and determining whether to retain our existing independent auditors or engage new independent auditors;

•

reviewing and approving the engagement of our independent auditors to perform audit services and any permissible non-audit services;

•

prior to engagement of any independent auditor, and at least annually thereafter, reviewing relationships that may reasonably be thought to bear on their independence, and assessing and otherwise taking the appropriate action to oversee the independence of our independent auditor;

•

reviewing our annual and quarterly financial statements and reports, including the disclosures contained therein and discussing the statements and reports with our independent auditors and management;

•

reviewing with our independent auditors and management significant issues that arise regarding accounting principles and financial statement presentation and matters concerning the scope, adequacy and effectiveness of our financial controls;

•

establishing procedures for the receipt, retention and treatment of complaints received by us regarding financial controls, accounting or auditing matters and other matters; and

•

reviewing and providing oversight of any related-person transactions in accordance with our related-person transaction policy and reviewing and monitoring compliance with legal and regulatory responsibilities, including our code of business conduct and ethics.

Compensation Committee

Our compensation committee is currently composed of Sylvia McBrinn, who is the chair of our compensation committee, Susan Moran, M.D., M.S.C.E. and Lawrence Steinman, M.D. The composition of our compensation committee meets the requirements for independence under current Nasdaq listing standards and SEC rules and regulations. Each member of this committee is also a non-employee director, as defined pursuant to Rule 16b-3 promulgated under the Exchange Act.

As more fully described in its charter, our compensation committee, has responsibility for, among other things:

•

reviewing, modifying and approving (or if it deems appropriate, making recommendations to the full board of directors regarding) our overall compensation strategy and policies;

- 11 -

•

reviewing and approving (or if it deems appropriate, making recommendations to the full board of directors regarding) the compensation and other terms of employment of our executive officers;

•

reviewing and approving (or if it deems appropriate, making recommendations to the full board of directors regarding) performance goals and objectives relevant to the compensation of our executive officers and assessing their performance against these goals and objectives;

•

reviewing and approving (or if it deems it appropriate, making recommendations to the full board of directors regarding) the equity incentive plans, compensation plans and similar programs advisable for us, as well as modifying, amending or terminating existing plans and programs;

•

evaluating risks associated with our compensation policies and practices and assessing whether risks arising from our compensation policies and practices for our employees are reasonably likely to have a material adverse effect on us;

•

reviewing and making recommendations to the full board of directors regarding the type and amount of compensation to be paid or awarded to our non-employee board members;

•

administering our equity incentive plans and establishing policies with respect to equity compensation arrangements; and

•

reviewing the competitiveness of our executive compensation programs and evaluating the effectiveness of our compensation policy and strategy in achieving expected benefits to us.

The agenda for each meeting is usually developed by the Chair of the compensation committee, in consultation with the Company's Senior Vice President: Human Resources and 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 compensation or individual performance objectives.

Our compensation committee is authorized to select, engage, compensate and terminate compensation consultants, legal counsel and such other advisors, as it sees fit, to assist in carrying out their responsibilities and functions, including the oversight of our overall compensation philosophy, compensation plans and benefits programs and our executive compensation programs and related policies. In 2024, the compensation committee continued to retain the services of Aon's Talent Solutions practice, a division of Aon plc (“Aon”), which is part of the Rewards Solutions practice at Aon plc, to provide advice and recommendations on competitive market practices and to evaluate our executive and non-employee director compensation programs and practices and to provide advice and ongoing assistance on our equity programs. Aon provided no other services to the Company in 2024. The compensation committee has determined that none of the work performed by Aon during the fiscal year ended December 31, 2024 raised any conflict of interest.

In December 2021, the board of directors created a board committee consisting solely of Dr. Short, the Company’s Chairman of the board of directors and CEO (the “Stock Plan Committee”), subject to annual terms and limitations adopted by the compensation committee. For 2024 and 2025, the compensation committee authorized the Stock Plan Committee to grant and determine the terms of stock options to newly hired employees or consultants under the 2020 Equity Incentive Plan and any successor plan, subject to certain limitations, including an aggregate maximum share limit. The Stock Plan Committee does not have authority to award options to directors, officers, holders of more than 10% of the Company’s securities or the CEO’s direct reports.

In addition, the compensation committee may establish and delegate authority to one or more subcommittees consisting of one or more of its members, when the compensation committee deems it appropriate to do so in order to carry out its responsibilities.

NOMINATIONS PROCESS AND DIRECTOR QUALIFICATIONS

Nomination to the Board of Directors

Candidates for nomination to our board of directors are selected by our board of directors based on the recommendation of our nominating and corporate governance committee in accordance with its charter, our amended and restated certificate of incorporation and amended and restated bylaws, our Corporate Governance Guidelines and the criteria approved by our board of directors regarding director candidate qualifications. In recommending candidates for nomination, our nominating and corporate governance committee considers candidates recommended by directors, officers, employees, stockholders and others, using the same criteria to evaluate all candidates.

Additional information regarding the process for properly submitting stockholder nominations for candidates for nomination to our board of directors is set forth below under “Requirements for Stockholder Proposals to be considered for inclusion in our proxy materials for our 2026 Annual Meeting” and “Requirements for Stockholder Proposals to be presented at our 2026 Annual Meeting.”

Director Qualifications

With the goal of developing a diverse, experienced and highly qualified board of directors, our nominating and corporate governance committee is responsible for developing and recommending to our board of directors the desired qualifications, expertise and characteristics of members of our board of directors, including any specific minimum qualifications that the committee believes must be met by a committee-recommended nominee for membership on our board of directors and any specific qualities or skills that the committee believes are necessary for one or more of the members of our board of directors to possess.

Because the identification, evaluation and selection of qualified directors is a complex and subjective process that requires consideration of many intangible factors, and will be significantly influenced by the particular needs of our board of directors from time to time, our board of directors has not adopted a specific set of minimum

- 14 -

qualifications, qualities or skills that are necessary for a nominee to possess, other than those that are necessary to meet U.S. legal, regulatory and Nasdaq listing requirements and the provisions of our amended and restated certificate of incorporation and amended and restated bylaws, our Corporate Governance Guidelines and the charters of the committees of our board of directors. Our nominating and corporate governance committee considers possible candidates from any source, including stockholders, for nominees for directors. All stockholder nominees for director will be considered by the nominating and corporate governance committee in the same manner as any other nominee. When considering nominees, our nominating and corporate governance committee may take into consideration many factors including, among other things, a candidate’s independence, integrity, diversity, skills, financial and other expertise, breadth of experience, knowledge about our business or industry and ability to devote adequate time and effort to responsibilities of our board of directors in the context of its existing composition. Our board of directors does not have a formal policy with respect to diversity and inclusion; however, it affirms the value placed on diversity within our Company. Through the nomination process, our nominating and corporate governance committee seeks to promote board membership that reflects a diversity of business experience, expertise, viewpoints, personal backgrounds and other characteristics that are expected to contribute to our board of directors’ overall effectiveness. Further, our board of directors is committed to actively seeking highly qualified women and individuals from minority groups to include in the pool from which new candidates are selected. The brief biographical description of each director set forth in “Proposal One: Election of Directors” below includes the primary individual experience, qualifications, attributes and skills of each of our directors that led to the conclusion that each director should serve as a member of our board of directors at this time.

Director Stock Ownership Guidelines

Our Board of Directors has instituted the following stock ownership guidelines for its non-employee directors to better align our directors’ interests with those of our stockholders.

The guideline ownership must be obtained within five years. Director ownership is evaluated annually as of December 31 using the highest closing price of the Company’s common stock in the fiscal year of evaluation. Shares that count toward meeting the stock ownership guidelines include shares owned directly, full value awards (e.g., RSUs), vested stock options (spread value) and shares owned directly by the director's spouse, dependent children and/or trust.

PROPOSAL THREE: NON-BINDING ADVISORY VOTE ON THE EXECUTIVE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

Our compensation programs are designed to provide long-term and currently-paid compensation and cash and non-cash compensation for our executive officers in order to align the compensation of our executive officers with our performance on a short-term and long-term basis. This proposal provides stockholders with the opportunity to cast a non-binding, advisory vote on the Company’s executive compensation practices and principles.

In 2022, our stockholders recommended that the non-binding, advisory vote on executive compensation be held every year. Accordingly, we have included this proposal for consideration at the Annual Meeting.

Stockholders should consider the compensation programs and their implementation, including the section entitled “Executive Compensation,” the compensation tables and any other executive compensation disclosure below, and cast a non-binding, advisory vote either to endorse or not endorse our executive compensation programs through the following resolution:

“RESOLVED: That the compensation paid to the Company’s named executive officers in 2024, as disclosed pursuant to Item 402 of Regulation S-K, including the Compensation Overview, compensation tables, and narrative discussion is hereby approved by the stockholders of the Company, on a non-binding, advisory basis.”

This vote is being provided pursuant to Section 14A of the Exchange Act. While the vote does not bind our board of directors to any particular action, the board of directors and the compensation committee thereof expects to take into account the outcome of this vote in considering future compensation programs. The next advisory vote on our executive compensation will be at the 2026 Annual Meeting.

OUR BOARD OF DIRECTORS RECOMMENDS A VOTE "FOR" APPROVAL OF proposal three.

Executive Summary

Fiscal 2024 Financial and Business Highlights

We are a clinical-stage biopharmaceutical company developing our novel class of highly specific and selective antibody-based therapeutics for the treatment of solid tumor cancer. Our conditionally active biologics (“CAB” or “CABs”) capitalize on our proprietary discoveries with respect to tumor biology, enabling us to target known and widely validated tumor antigens that have previously been difficult or impossible to target.

Since the commencement of our operations, we have focused substantially all of our resources on conducting research and development activities, including drug discovery, preclinical studies and clinical trials of our product candidates, including the ongoing Phase 2 clinical trial of mecbotamab vedotin, the ongoing Phase 1 clinical trial of BA3182, and advancing strategic collaboration discussions for ozuriftamab vedotin and evalstotug, establishing and maintaining our intellectual property portfolio, manufacturing clinical and research material through third parties, hiring personnel, establishing product development and commercialization collaborations with third parties, raising capital, and providing general and administrative support for these operations. Since 2014, such research and development activities have exclusively related to the research, development, manufacture, and Phase 1 and Phase 2 clinical testing of our CAB antibody-based product candidates and the strengthening of our proprietary CAB technology platform and pipeline. We do not have any products approved for sale, and we have not generated any revenue from product sales.

Achievement of Corporate Performance Goals in 2024

In 2024, we achieved key corporate performance goals with respect to certain clinical development milestones, research and development goals, and strategic objectives, as described in more detail in the section titled “Annual Cash Incentive Bonuses—2024 Corporate Goals.” Our key achievements in 2024 included the following:

Deliver on near-term value drivers: completed registrational strategy and trial-enabling studies for our CAB portfolio of mecbotamab vedotin, ozuriftamab vedotin and evalstotug; completed the Context Licensing Agreement.

Build on the vision for the future: advanced the clinical and preclinical pipeline by filing an IND for Nectin 4 and partnered BA3362; delivered on our publications plan and efforts to increase global awareness and visibility of CAB technology.

Build the Vision for the Future

Our mission is to develop and commercialize innovative antibody-based therapeutics for the treatment of solid tumors that are designed to bind depending on the physical and chemical properties of tumors and their

- 27 -

microenvironment. We believe that our proprietary technology and approach have the potential to transform cancer therapy by decreasing systemic toxicities and improving efficacy.

Say-On-Pay

At the 2024 Annual Meeting of Stockholders, the Company’s stockholders voted to approve, on an advisory basis, the compensation of the Company’s NEOs, as described in the Company’s 2024 proxy statement. The Compensation Committee considered the voting results and feedback from stockholders and whether the program was effective in fiscal 2024 and reflects stockholder interests. The Compensation Committee has not made any changes to the overall executive compensation program, other than granting restricted stock unit awards rather than option awards to our executives (as described in greater detail in the section titled “Long-Term Equity Incentives”), because it believes the current compensation framework, which focuses on pay for performance and long-term growth, is operating as intended. The Compensation Committee believes that the program is effectively aligning pay with individual and Company performance and properly incentivizing and retaining our NEOs in a highly competitive market. The Compensation Committee will continue to consider feedback from stockholders and to monitor trends and developments to ensure that the Company’s executive compensation programs remain competitively positioned for executive talent and aligned with the interests of stockholders.

Executive Compensation Philosophy and Objectives

We operate in a highly competitive and rapidly evolving market. Our ability to compete and succeed in our market is directly correlated to our ability to recruit, incentivize, and retain talented individuals in the areas of product development, and general and administrative functions. The market for skilled personnel in the biotechnology and biopharmaceutical industries is very competitive. Our Compensation Committee believes that the most effective compensation program is designed to attract and reward talented individuals who possess the skills necessary to support our business objectives and create long-term value for our stockholders, expand our business, and assist in the achievement of our strategic goals.

Our Compensation Committee believes executive compensation packages provided to our executives, including the NEOs, should include both cash and stock-based compensation that achieve the following goals:

•

Recruit, motivate and retain highly qualified executive officers who possess the skills and leadership necessary to grow our long-term stockholder value;

•

Reward our executives for achieving or exceeding short-term individual and company goals that drive our growth;

•

Provide long-term retention and incentives to our executives that align their interests with the long-term interests of our Company and our stockholders, thereby incentivizing management to increase stockholder value; and

•

Provide compensation packages that are competitive, reasonable and fair relative to peers and the overall market.

Our Compensation Committee periodically reviews our compensation program design to ensure that it is aligned with the interests of our stockholders and our business goals, and that the total compensation paid to our employees and directors is fair, reasonable and competitive. Our Compensation Committee assesses market best practices in executive compensation to continually refine our programs, which have the following key features:

•

Attract and retain key talent;

•

Offer a total compensation program that flexibly adapts to changing economic, regulatory and organizational conditions, and takes into consideration the compensation practices of peer companies;

•

Pay for performance;

•

Provide a significant portion of compensation that is at-risk and tied to our financial performance, strategic objectives or stock price;

•

Align executive interests with our stockholders; and

•

A significant portion of total compensation is either earned based on clinical development milestones, research and development goals, and strategic objectives, or varies based on our stock price, which contributes to value creation for our stockholders.

WHAT WE DO	WHAT WE DO NOT DO
☑ Link Pay for Performance: We link pay for performance and stockholder interests by weighting compensation toward short-term cash incentive awards and long-term equity awards which are tied to the value of our share price.	☒ Single Trigger Acceleration: We do not provide for “single trigger” acceleration upon a change of control.
☑ Incentivize a Strong Ownership Mentality: In February 2024, we granted equity awards to our executive officers, which we use to motivate long-term performance and strongly align the interests of our executives with those of our stockholders.	☒ Executive Perquisites: We do not maintain any executive-specific benefit or perquisite programs.
☑ Corporate Strategy Alignment: Our Compensation Committee establishes incentive compensation programs based on metrics that are aligned with our corporate strategy and designed to grow stockholder value.	☒ Tax Gross-Ups: We do not provide tax gross-ups for “excess parachute payments” or any other executive benefits.
