GENERAL INFORMATION ABOUT THE MEETING

Who May Vote

You may vote if our records show that you own shares of BioLargo as of October 15, 2026 (the “Record Date”). As of the Record Date, we had a total of 334,661,950 shares of common stock issued and outstanding, which were held of record by approximately 500 stockholders, and beneficially by approximately 6,100 stockholders. As of the Record Date, we had no shares of preferred stock outstanding. You are entitled to one vote for each share that you own.

Voting Your Proxy

If a broker, bank or other nominee holds your shares, you will receive instructions from them that you must follow in order to have your shares voted. If a bank, broker or other nominee holds your shares and you wish to attend the meeting and vote in person, you must obtain a “legal proxy” from the record holder of the shares giving you the right to vote the shares.

If you hold your shares in your own name as a holder of record at the Company’s transfer agent, American Stock Transfer & Trust, you may instruct the proxy holders how to vote your common stock in one of the following ways:

Of course, you may also choose to attend the meeting and vote your shares in person. Unless you do so, the proxy holders will vote your shares in accordance with your instructions on the proxy card. If you sign and return a proxy card without giving specific voting instructions, your shares will be voted as recommended by our Board of Directors.

Proposals to be Presented

We are not aware of any proposals to be presented other than the proposals described in this Proxy Statement. If any proposals not described in the Proxy Statement are properly presented at the meeting, the proxy holders will use their own judgment to determine how to vote your shares. If the meeting is adjourned, the proxy holders can vote your shares on the new meeting date as well, unless you have revoked your proxy instructions.

Changing Your Vote

To revoke your proxy instructions if you are a holder of record, you must (i) advise our Corporate Secretary in writing before the proxy holders vote your shares, (ii) deliver later proxy instructions, or (iii) attend the meeting and vote your shares in person. If your shares are held by a bank, broker or other nominee, you must follow the instructions provided by the bank, broker or nominee.

Cost of This Proxy Solicitation

We will pay the cost of this proxy solicitation. 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 will reimburse these individuals for their reasonable out-of-pocket expenses.

How Votes are Counted

The Annual Meeting will be held if a majority of the outstanding common stock entitled to vote is represented at the meeting in person or by proxy. If you have returned valid proxy instructions or attend the meeting in person, your common stock will be counted for the purpose of determining whether there is a quorum, even if you wish to abstain from voting on some or all proposals at the meeting. The vote required to approve the proposals described herein is governed by Delaware law and the Company's bylaws. The minimum vote required to approve each proposal, other than the election of directors, is a majority of the total votes cast on such proposal, provided a quorum is present. As a result, in accordance with Delaware law, abstentions and broker non-votes will have the effect of a vote “Against” each such proposal.

Abstentions and Broker Non-Votes

Shares that are voted “WITHHELD” or “ABSTAIN” are treated as being present for purposes of determining the presence of a quorum and as entitled to vote on a particular proposal at the Annual Meeting. If you hold your common stock through a bank, broker or other nominee, the broker may be prevented from voting shares held in your account on some proposals (a “broker non-vote”) unless you have given voting instructions to the bank, broker or nominee. Shares that are subject to a broker non-vote are counted for purposes of determining whether a quorum exists but not for purposes of determining whether a proposal has passed.

Our Voting Recommendations

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. However, if no specific instructions are given, the shares will be voted in accordance with the following recommendations of our Board of Directors:

Deadlines for Receipt of Stockholder Proposals

Stockholders may present proposals for action at a future meeting only if they comply with the requirements of the proxy rules established by the SEC and our bylaws. Stockholder proposals that are intended to be included in our Proxy Statement and form of Proxy relating to the meeting for our 2027 Annual Meeting of Stockholders under rules set forth in the Securities Exchange Act of 1934, as amended, or the Securities Exchange Act, must be received by us no later than March 31, 2027, to be considered for inclusion. All proposals should be addressed to the Corporate Secretary, BioLargo, Inc., 14921 Chestnut St., Westminster, California 92683.

Table of Contents

The Compensation Committee reviews the compensation for all our officers and directors and affiliates. Linda Park has served as Chairman since November 2022. Mr. Marshall and Ms. Bray also serve on the Compensation Committee. The Compensation Committee acted by consent four times during fiscal year 2025 and three times during fiscal year 2024. 

Our board of directors did not modify any action or recommendation made by the Compensation Committee with respect to executive compensation for the 2025 or 2024 fiscal years. It is the opinion of the Compensation Committee that the executive compensation policies and plans provide the necessary total remuneration program to properly align their performance and the interests of our stockholders using competitive and equitable executive compensation in a balanced and reasonable manner, for both the short and long term.

The Nominating and Corporate Governance Committee was established in November 2018. Its responsibilities include to identify and screen individuals qualified to become members of the Board, to make recommendations to the Board regarding the selection and approval of the nominees for director to be submitted to a stockholder vote at the annual meeting of stockholders, subject to approval by the Board, to development corporate governance guidelines and oversee corporate governance practices, to develop a process for an annual evaluation of the Board and its committees, to review all director compensation and benefits, to review, approve and oversee related party transactions, to develop and recommend director independent standards, and to develop and recommend a Company code of conduct, to investigate any alleged breach and enforce the provisions of the code. Since November 2022, the committee has been comprised of Christina Bray, as chairperson, and Mr. Marshall and Ms. Park. This committee did not meet in fiscal years 2025 or 2024.

Our board of directors follows the written code of ethics that applies to its principal executive officers, principal financial officer, principal accounting officer or controller, or persons performing similar functions.

Board Leadership Structure

Mr. Calvert serves as both principal executive officer and Chairman of the Board. The Company does not have a lead independent director. The board has four independent directors who provide active and effective oversight of our strategic decisions: Dennis Marshall, Jack Strommen, Linda Park and Christina Bray. As of the date of this filing, the Company has determined that the leadership structure of the Board has permitted the Board to fulfill its duties effectively and efficiently and is appropriate given the size and scope of the Company and its financial condition.

The Board’s Role in Risk Oversight

As a smaller reporting company, our executive management team, consisting of Messrs. Calvert and Code, are also members of our Board. Our board of directors, including our executive management members and independent directors, is responsible for overseeing our executive management team in the execution of its responsibilities and for assessing our Company’s approach to risk management. Our board of directors exercises these responsibilities on an ongoing basis as part of its meetings and through its committees. Each member of the management team has direct access to the other Board members, and our committees of our board of directors, to ensure that all risk issues are frequently and openly communicated. Our board of directors closely monitors the information it receives from management and provides oversight and guidance to our executive management team regarding the assessment and management of risk. For example, our board of directors regularly reviews our company’s critical strategic, operational, legal and financial risks with management to set the tone and direction for ensuring appropriate risk taking within the business.

Compensation Committee Interlocks and Insider Participation

During fiscal years 2025 and 2024, the Compensation Committee consisted of three members – Christina Bray, Linda Park, and Dennis Marshall, neither of whom have ever been an employee or officer of the Company, and neither of whom have had transactions with the Company that would require disclosure under Item 404 of Regulation S-K (see “Transactions with Related Parties”, below). Each of Ms. Park and Ms. Bray received options upon their election to the board, and each of the independent board members receive stock options as payment of board fees each quarter.

Section 16(a) Beneficial Ownership Reporting Compliance

Section 16(a) of the Securities Exchange Act of 1934 requires our directors, certain officers and persons holding 10% or more of the Company’s Common stock to file reports regarding their ownership and regarding their acquisitions and dispositions of our Common stock with the SEC. Such persons are required by SEC regulations to furnish the Company with copies of all Section 16(a) forms they file.

To our knowledge, based solely upon review of Forms 3, 4, and 5 (and amendments thereto) and written representations provided to us by executive officers, directors and stockholders beneficially owning 10% or greater of the outstanding shares, we believe that such persons filed pursuant to the requirements of the SEC on a timely basis during the year ended December 31, 2024.

The Code Employment Agreement can automatically renew for one-year periods on April 29th of each year but may be terminated “without cause” at any time upon 120 days’ notice, and upon such termination, Mr. Code would not receive the severance originally provided for. All other terms in the 2007 agreement remain the same in the Code Employment Agreement.

This non-binding advisory vote is commonly referred to as a “say on pay” vote. The next non-binding advisory vote on executive compensation will occur at our 2027 Annual Meeting of Stockholders.

As described more fully in the Compensation Discussion and Analysis portion of this proxy, our executive compensation program has been designed to attract, motivate and retain individuals with the skills needed to formulate, implement and execute strategy to further the creation of stockholder value.

We encourage you to carefully review the “Executive Compensation” discussion beginning on page 9 of this Proxy Statement for additional details on our executive compensation, including our compensation philosophy and objectives, as well as the processes our Compensation Committee used to determine the structure and amounts of the compensation of our named executive officers.

We are asking you to indicate your support for the compensation of our named executive officers as described in this Proxy Statement. This vote is not intended to address any specific item of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies and practices described in this Proxy Statement. Accordingly, we are asking you to vote “FOR” the approval, on an advisory basis, of the following resolution at the Annual Meeting:

“RESOLVED, that the compensation paid to BioLargo, Inc.’s named executive officers, as disclosed pursuant to the Securities and Exchange Commission's compensation disclosure rules, including the “Executive Compensation” discussion and analysis, the compensation tables and the narrative discussion set forth in the Proxy Statement, is hereby approved.”

While the results of this advisory approval are not binding, the Compensation Committee will consider the outcome of the vote in deciding whether to take any action as a result of the vote and when making future compensation decisions for named executive officers.

OUR BOARD OF DIRECTORS RECOMMENDS THAT YOU VOTE "FOR" THE APPROVAL, ON AN ADVISORY BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS AS DISCLOSED IN THIS PROXY STATEMENT.

REPORT OF AUDIT COMMITTEE

The following report of the Audit Committee does not constitute soliciting material and should not be deemed filed or incorporated by reference into any of our other filings under the Securities Act or the Exchange Act, except to the extent that we specifically incorporate this report by reference therein, and shall not be deemed to be soliciting material or otherwise deemed filed under either such Act.

The Audit Committee is currently comprised of three independent directors, all of whom are independent under the rules of the SEC and Nasdaq. Mr. Marshall serves as Chairman of the Audit Committee, with board members Linda Park and Christina Bray as committee members. The Board has determined that Mr. Marshall qualifies as an “audit committee financial expert” as defined in Item 401(h) of Regulation S-K of the Securities Exchange Act of 1934, as amended. The duties and responsibilities of a member of the Audit Committee are in addition to his or her duties as a member of the Board. The Audit Committee operates under a written charter, a copy of which is available on our corporate website, www.biolargo.com. The Audit Committee met four times during 2024.

The Audit Committee’s primary duties and responsibilities are to:

Management is responsible for the Company’s internal controls and the financial reporting process. The Company’s independent registered public accounting firm is responsible for performing an independent audit of the Company’s consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board and issuing a report thereon. The Audit Committee’s responsibility is to monitor and oversee these processes.

In carrying out these responsibilities, the Audit Committee monitored the Company’s operational effectiveness regarding the progress and completion of the implementation of the Company’s internal controls.

In overseeing the preparation of the Company’s financial statements, the Audit Committee met with the Company’s Chief Financial Officer and management, and held meetings with the Company’s independent registered public accounting firm, both in the presence of management and privately, to review and discuss all financial statements prior to their issuance, the overall scope and plans for the preparation of the financial statements and respective audit, and the evaluation of the Company’s internal controls and significant accounting issues. Management advised the Audit Committee that all financial statements were prepared in accordance with accounting principles generally accepted in the United States of America, and the Audit Committee discussed the statements with both management and the Company’s independent registered public accounting firm. In accordance with Section 204 of the Sarbanes-Oxley Act of 2002 and the Public Company Accounting Oversight Board (“PCAOB”) Audit Standard No. 16-1301 (Communications with Audit Committees), the Audit Committee has discussed with the Company’s independent registered public accounting firm all matters required to be discussed under the Sarbanes-Oxley Act and the foregoing standards.  In addition, the Audit Committee has received the written disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent registered public accounting firm’s communications with the Audit Committee concerning independence, and has discussed with the independent registered public accounting firm its independence.

With respect to the Company’s independent registered public accounting firm, the Audit Committee, among other things, discussed with Haskell & White LLP and Hacker Johnson & Smith PA matters relating to their independence, including the written disclosures made to the Audit Committee as required by the PCAOB Rule 3526, Communications with Audit Committees Concerning Independence.  The Audit Committee also reviewed and approved the audit fees of Haskell & White LLP and Hacker Johnson & Smith PA. 

On the basis of these reviews and discussions, the Audit Committee (i) appointed Hacker Johnson & Smith PA as the Company’s independent registered public accounting firm for the year ended December 31, 2025 and (ii) recommended to the Board that the Board approve the inclusion of the Company’s audited financial statements in the Form 10-K for the year ended December 31, 2025 for filing with the SEC.
