IMPORTANT

Whether or not you expect to attend the virtual-only 2026 Annual Shareholders’ Meeting, we strongly urge you to cast your vote by telephone or through the Internet by following the instructions included on the Notice of Internet Availability of Proxy Materials that you received, or if you received a paper copy of the proxy card, to mark, date, sign and return the proxy card in the envelope provided, prior to the meeting on June 2, 2026, to help ensure the presence of a quorum for the meeting and to save the expense and extra work of additional solicitation. Voting by proxy by any method prior to the meeting will not prevent you from attending the 2026 Annual Shareholders’ Meeting virtually or revoking your prior vote and voting at the 2026 Annual Shareholders’ Meeting.

In accordance with rules promulgated by the SEC, we are providing access to our proxy materials, including this proxy statement and our annual report on Form 10-K for the year ended December 31, 2025, over the Internet. As a result, we are mailing to many of our shareholders a Notice of Internet Availability of Proxy Materials instead of a paper copy of our proxy materials. The notice contains instructions on how to access those proxy materials over the Internet, as well as instructions on how to request a paper copy of our proxy materials. All shareholders who do not receive a notice will receive a paper copy of our proxy materials by mail. We believe that this process reduces the environmental impact. and lowers the costs of printing and distributing our proxy materials.

General Information

Paper copies of our proxy materials are being mailed or delivered on or about April 21, 2026, to shareholders of record who have previously requested to receive paper copies of proxy materials. The list of frequently asked questions is attached to this proxy statement as Appendix A. Unless otherwise stated, all references in this proxy statement to “Mannatech,” the “Company,” “us,” “our,” or “we” are to Mannatech, Incorporated, a Texas corporation.

Shareholders Entitled to Vote

Shareholders who owned our common stock as of the close of business on April 6, 2026, the record date, are called “shareholders of record” and are entitled to vote at the 2026 Annual Shareholders’ Meeting. As of April 6, 2026, we had 1,929,670 outstanding shares of our common stock, $0.0001 par value per share, which is our only class of outstanding voting securities. As of April 6, 2026, we had 985 shareholders of record. Each share of our common stock entitles a shareholder to one vote. A complete list of direct shareholders entitled to vote at the 2026 Annual Shareholders’ Meeting will be available for examination by shareholders for purposes pertaining to the 2026 Annual Shareholders’ Meeting at our corporate office in Flower Mound, Texas during normal business hours from May 22, 2026, until June 1, 2026. The shareholder list will also be available for review prior to and during the 2026 Annual Shareholders’ Meeting to be held on June 2, 2026, or electronically at www.virtualshareholdermeeting.com/MTEX2026.

Voting in Person

If you are a shareholder of record and plan to participate in the virtual-only 2026 Annual Shareholders’ Meeting via webcast at www.virtualshareholdermeeting.com/MTEX2026, you may login by entering the 16-digit control number you received with your proxy materials. Instructions on how to participate are posted at www.virtualshareholdermeeting.com/MTEX2026. You will be able to vote your shares while attending the virtual-only 2026 Annual Shareholders’ Meeting by following the instructions on the website. If a broker or bank holds your Mannatech shares in street name, and you wish to vote at the virtual-only 2026 Annual Shareholders’ Meeting, you will need to obtain a legal proxy form from your broker or bank that holds your shares of record and you must have that document when you login.

Voting by Proxy

The proxy process is the means by which shareholders can exercise their rights to vote for the election of directors and other strategic corporate proposals. The notice of meeting and this proxy statement provide notice of a scheduled shareholder meeting, describe the proposals to be voted on by shareholders at the meeting and include other information required to be disclosed to shareholders. Shareholders may vote by telephone, through the Internet, or by returning a proxy card, without having to attend the shareholder meeting online.

By executing a proxy, you authorize Larry Jobe or Tyler J. Rameson to act as your proxy to vote your shares in the manner that you specify. The proxy voting mechanism is vitally important to us. In order for us to obtain the necessary shareholder approval of proposals, a “quorum” of shareholders (a majority of the issued and outstanding shares of common stock as of the record date entitled to vote) must be represented at the virtual meeting, or by proxy. If insufficient shareholders decide to attend a shareholder meeting, voting by proxy is necessary to obtain a quorum and complete the shareholder vote. It is important that you attend the meeting either online or grant a proxy to vote your shares to assure a quorum is present so corporate business may be transacted. If a quorum is not present, we must postpone the meeting and solicit additional proxies; this is an expensive and time-consuming process that is not in the best interest of the Company or our shareholders.

Properly executed votes by proxy received prior to or at the 2026 Annual Shareholders’ Meeting on June 2, 2026, or at any adjournment(s) or postponement(s) thereof, will be counted by Broadridge Financial Solutions, Inc., our Inspector of Elections. If a shareholder specifies how such shareholder’s proxy-vote is to be cast on any business to come before the meeting, such proxy-vote will be voted in accordance with such specifications. If no specification is made on a properly executed proxy card, the shareholder’s vote by proxy will be voted “FOR” Proposals 1, 2 and 3, consistent with the recommendations made by the Board and as the proxy holder may determine in his discretion with respect to any other matters properly presented for a vote at the 2026 Annual Shareholders’ Meeting. Other than the proposals described in this proxy statement, we are not aware of any other matters to be presented at the 2026 Annual Shareholders’ Meeting.

Revoking or Changing a Proxy

A shareholder may revoke a vote by proxy at any time prior to the 2026 Annual Shareholders’ Meeting. If you are a shareholder of record with direct ownership over your Mannatech common stock, your proxy can be revoked by (i) timely delivery of a written revocation delivered to Erin K. Barta, General Counsel and Corporate Secretary, Mannatech, Incorporated, 1410 Lakeside Parkway, Suite 200, Flower Mound Texas 75028; (ii) submission of another valid proxy bearing a later date; or (iii) attendance at the virtual-only 2026 Annual Shareholders’ Meeting and notice to the Inspector of Elections that you intend to vote your shares at the virtual-only meeting. If your Mannatech shares are held in street name by a broker or bank (“broker”), you must contact your broker in order to revoke your proxy, but generally, you may change your vote by submitting new voting instructions to your broker, trustee or nominee, or, if you have obtained a legal proxy from your broker or nominee giving you the right to vote your shares, by logging-in to the website at www.virtualshareholdermeeting.com/MTEX2026 and entering the 16-digit control number you received with your proxy materials.

Table of Contents

Effects of Not Voting

The effect of not voting depends on how you own your shares. If you own shares directly, as a holder of record, rather than indirectly through a broker of record, your unvoted shares will not be represented at our meeting and will not count toward the quorum requirement. Assuming a quorum is obtained, your unvoted shares will not affect whether a proposal is approved or rejected. If you own shares through a broker and do not vote, your broker may represent your shares at the meeting for purposes of obtaining a quorum. As described below, if you own your shares through a broker and you do not vote, your broker may or may not vote your shares, depending upon the proposal.

If you own your shares through a broker and you do not vote, your broker may vote your shares at its discretion on “routine matters.” However, with respect to other proposals, a broker may not vote a non-voting shareholder’s shares. With respect to proposals on which a broker may not vote a non-voting shareholder’s shares, the aggregate number of non-voted shares is reported as “broker non-votes” (shares held by brokers or nominees for which they have no discretionary power to vote on a particular matter and have received no instructions from the beneficial owners or persons entitled to vote) and counted only for purposes of determining a quorum.

If you do not vote your shares on Proposal 1 (Election of Director) and Proposal 3 (“Say-on-Pay” Advisory Vote), your brokerage firm cannot vote them for you and they will remain unvoted. Therefore, it is very important that you vote your shares for all proposals. Proposal 2 (Ratification of Auditors) set forth in this proxy statement is a routine matter on which brokers will be permitted to vote your shares at the broker’s discretion if you do not provide your broker with instructions on how to vote on this matter.

Direct Ownership

For the purpose of determining how to vote your shares at the 2026 Annual Shareholders’ Meeting, registered holders of record are deemed to have “direct ownership” over their Mannatech shares if they hold their shares directly in their name. This is typically evidenced by the receipt of our mailings directly from us or from our transfer agent, Computershare.

Beneficial Ownership

For the purposes of determining how to vote your shares at the 2026 Annual Shareholders’ Meeting, you are deemed to have “beneficial ownership” over your Mannatech shares if you: (i) previously deposited your stock certificates with a broker; (ii) purchased your shares directly through a broker; or (iii) sent your stock certificates to a broker to be deposited into your brokerage account. Beneficial ownership is typically evidenced by a shareholder’s receipt of our mailings either from a broker or through a solicitor, which is usually Broadridge Financial Solutions, Inc.

As a beneficial owner, a shareholder still holds Mannatech shares, but neither we nor our transfer agent has access to any list of individual shareholders’ names from the various brokers of record. The only information our transfer agent has concerning shareholders who own stock through a broker is the broker’s name, the aggregate total number of shares held by each broker on behalf of their clients, and the aggregate number of votes cast for any of our proposals.

Table of Contents

WE CAUTION OUR SHAREHOLDERS THAT each brokerage firm has a unique set of voting instructions. As a result, a shareholder should always read all the information provided in each of the proxy information packets received and follow the specific voting instructions enclosed in each packet with respect to applicable telephone numbers, Internet addresses, mailing addresses, and attending or voting at the 2026 Annual Shareholders’ Meeting.

If a shareholder receives more than one proxy information packet, such shareholder’s shares are registered in more than one account. Again, remember that each proxy information packet may have different voting instructions, account or control numbers, mailing addresses, Internet addresses, and telephone numbers. As a result, each shareholder should be cautioned to use only the set of voting instructions, account and control numbers, addresses, and telephone numbers provided in such shareholder’s proxy information packet to ensure such shareholder’s vote for all of its owned shares is properly included in the tabulation of votes for our meeting.

Beneficial shareholders are also instructed to read their proxy-voting card instructions given to them by their brokers or their brokers’ solicitors prior to the meeting in order to obtain instructions on how to vote at the meeting. If a beneficial shareholder does not follow the brokers’ specific instructions, our Inspector of Elections is not allowed to count such beneficial shareholder’s vote at the 2026 Annual Shareholders’ Meeting.

Solicitation of Proxy-Votes

We may solicit proxy-votes through the mail, in person, and by telecommunications. We will bear all expenses in preparing, printing, and mailing the proxy materials to our shareholders.

Tabulating the Votes

A representative from Broadridge Financial Solutions, Inc., which will act as our Inspector of Elections, is responsible for tabulating the votes for the 2026 Annual Shareholders’ Meeting. The presence, in person (by attending virtually) or by proxy, of the holders of at least a majority of the shares of our common stock outstanding as of April 6, 2026, our record date, is necessary to establish a quorum for the 2026 Annual Shareholders’ Meeting. Abstentions and “broker non-votes,” if any, will be counted as shares present and entitled to vote for purposes of determining a quorum for the 2026 Annual Shareholders’ Meeting. A “broker non-vote” occurs when brokers holding shares in “street name” have not received voting instructions from the beneficial owner and either chooses not to vote those shares on a routine matter at the 2026 Annual Shareholders’ Meeting or is not permitted to vote those shares on a non-routine matter. If a proxy-voting card is signed by the shareholder but submitted without specific voting instructions, the shareholder’s vote will automatically be counted as a vote “FOR ALL” on Proposal 1 (Election of Director), and “FOR” on Proposal 2 (Ratification of Auditors), and “FOR” on Proposal 3 (“Say-on-Pay” Advisory Vote). If your shares are held in “street name” and you do not provide specific voting instructions to your broker, then your shares will not be included in the vote for Proposal 1 (Election of Director) or Proposal 3 (“Say-on-Pay” Advisory Vote) but will be voted at the discretion of your broker with respect to Proposal 2 (Ratification of Auditors).

For Proposal 1 (Election of Directors) — Assuming a quorum is obtained, our two Class III directors will be elected by a plurality of the shares represented, in person (by attending virtually) or by proxy, at the virtual-only 2026 Annual Shareholders’ Meeting and entitled to vote. This means that the nominees receiving the highest number of affirmative votes at the meeting will be elected as our Class III directors. Votes marked “FOR ALL” will be counted in favor of the nominees. Votes marked “WITHHOLD ALL” will be counted against the nominees. To specify differently, a shareholder must check the “FOR ALL EXCEPT” box and then write the name of the nominee for whom the shareholder wishes to vote against. Votes marked “WITHHOLD ALL” have no effect on the vote since a plurality of the votes is required for the election of the nominee. Shareholders may not abstain from voting with respect to the election of the directors.

A shareholder cannot write-in the names of additional nominees when voting by proxy or electronically. Shareholders who login to attend the virtual-only 2026 Annual Shareholders’ Meeting may vote on the proposals including the director nominees at www.virtualshareholdermeeting.com/MTEX2026, but shareholders cannot write-in candidates.

(THE BOARD RECOMMENDS A VOTE “FOR ALL” PROPOSAL 1.)

For Proposal 2 (Ratification of Auditors) — If a quorum is obtained, and a majority of the shares represented, in person (by attending virtually) or by proxy, at the virtual-only 2026 Annual Shareholders’ Meeting and entitled to vote, are in favor of Proposal 2, the ratification of the appointment of our independent registered public accounting firm for the year ended December 31, 2026, will be approved. Votes marked “FOR” Proposal 2 will be counted in favor of the ratification of the appointment of our independent registered public accounting firm for the year ending December 31, 2026. An abstention from voting on Proposal 2 will not be voted on that item, although it will be counted for purposes of determining the number of shares represented and entitled to vote. Accordingly, an “ABSTENTION” will have the same effect as a vote “AGAINST” Proposal 2.

(THE BOARD RECOMMENDS A VOTE “FOR” PROPOSAL 2.)

Table of Contents

For Proposal 3 (“Say-on-Pay” Advisory Vote) — If a quorum is obtained, and a majority of shares represented, in person (by attending virtually) or by proxy, at the virtual-only 2026 Annual Shareholders’ Meeting and entitled to vote, are in favor of Proposal 3, the current executive compensation program will be approved by shareholders on an advisory basis. Votes marked “FOR” Proposal 3 will be counted in favor of the current executive compensation program. An abstention from voting on Proposal 3 will not be voted on that item, although it will be counted for purposes of determining the number of shares represented and entitled to vote. Accordingly, an “ABSTENTION” will have the same effect as a vote “AGAINST” Proposal 3. “Broker non-votes” are not considered shares entitled to vote for purposes of Proposal 3 and thus will have no effect on the outcome of the approval, on an advisory basis, of our executive compensation program.

(THE BOARD RECOMMENDS A VOTE "FOR" PROPOSAL 3.)

Admission and Voting at Our 2026 Annual Shareholders’ Meeting

Voting at the virtual-only 2026 Annual Shareholders’ Meeting is limited to shareholders of record having evidence of ownership as of the record date, April 6, 2026. Shareholders who login at www.virtualshareholdermeeting.com/MTEX2026 and enter their 16-digit control number found in the proxy materials will be admitted to the meeting. If your shares are NOT held in your name, we may require you to show evidence of your ownership at our meeting when you login.

If you are a shareholder holding your shares in "street name" as of the close of business on the record date, you may gain access to the virtual meeting by following the instructions in the voting instruction card provided by your broker, bank or other nominee. You may not vote your shares electronically at the 2026 Annual Shareholders' Meeting unless you receive a valid proxy from your brokerage firm, bank, broker dealer or other nominee holder.

As a courtesy and as time permits, we will provide a brief question and answer period for our shareholders of record. Shareholders who login to the webcast and enter their 16-digit control will receive instructions on how to submit questions.

Shareholders of record will be able to vote electronically online upon verification of stock ownership. REMEMBER that beneficial shareholders must obtain a power of attorney form or legal proxy from their brokers prior to the 2026 Annual Shareholders’ Meeting in order for their votes at the virtual-only meeting to be counted since their brokers may have already reported their shares as “broker non-votes.” Prior to our June 2, 2026 meeting, beneficial shareholders are strongly urged to read their proxy-voting card instructions on how to vote at our 2026 Annual Shareholders’ Meeting. They should also contact their brokers by the Monday prior to our 2026 Annual Shareholders’ Meeting to ensure they obtain the proper paperwork in order to vote at our virtual meeting. If a beneficial shareholder does not follow its broker’s instructions, our Inspector of Elections will not count such shareholder’s vote at the virtual-only 2026 Annual Shareholders’ Meeting. The instructions are usually located on the back of each proxy-voting card.

PROPOSAL 2 — RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

Neither our Articles of Incorporation, Bylaws, nor any other applicable legal requirements require shareholder ratification of the selection of our independent registered public accounting firm. However, the Board, as a matter of good corporate governance, has always sought shareholder ratification of the appointment of our independent registered public accounting firm. The Board is seeking shareholder ratification of the appointment of BDO USA, P.C. as our independent registered public accounting firm for the fiscal year ending December 31, 2026. In the event our shareholders do not ratify our appointment of BDO USA, P.C., the Audit Committee and the Board will reconsider the appointment.

Our Audit Committee appoints our independent registered public accounting firm on an annual basis. The decision is based on a number of factors including the scope of the audit, the independence of the auditors, the estimated audit fees, and any non-auditing services that are performed by the independent registered public accounting firm.

Representatives from BDO USA, P.C. will attend the virtual-only 2026 Annual Shareholders’ Meeting and will have the opportunity to make a statement, if they so desire. They will also be available to respond to any appropriate questions from our shareholders.

Pre-Approval Policies and Procedures

Our Audit Committee must pre-approve all services provided by our independent registered public accounting firm. The non-audit services, specified in Section 10A(g) of the Exchange Act may not be provided by our independent registered public accounting firm.

Each year, the approval of the estimated annual audit, audit-related services, and routine tax services takes place at an Audit Committee meeting. In addition, during the course of the year, requests for unforeseen or additional allowable services to be provided by our independent registered public accounting firm must be preapproved by our Audit Committee, except for those qualifying for the “de minimis exception.” The de minimis exception provides that the pre-approval requirements for certain non-audit services may be waived if:

•

the aggregate amount of such non-audit services provided constitutes not more than 5% of the total fees paid to our independent registered public accounting firm in the calendar year that such non-audit services are provided;

•

such services were recognized as non-audit services at the time they were provided; and

•

such services are promptly brought to the attention of our Audit Committee.

Our Audit Committee may delegate to its Chairman the authority to grant pre-approvals. In such event, the decisions of the Chairman of the Audit Committee regarding pre-approvals will then be presented to our full Audit Committee at the next scheduled meeting.

Our independent registered public accounting firm provides a revised estimate for the year, by project, for all planned and approved services to our Chief Financial Officer prior to each Audit Committee annual planning meeting. The revised estimate is then reviewed at our Audit Committee annual planning meeting.

Fees Paid to Our Independent Registered Public Accounting Firm

For the years ended December 31, 2025 and 2024, we were billed the following fees by our current independent registered public accounting firm, BDO USA, P.C. as follows:

Type of Service	2025		2024
	*(in thousands)*

The “de minimis exception” described above was not used for any fees paid to BDO USA, P.C. in 2025 and 2024. All fees were pre-approved by our Audit Committee. The members of our Audit Committee believe the payment of all fees set forth above did not prohibit BDO USA, P.C. from maintaining its independence.

(THE BOARD RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF OUR INDEPENDENT REGISTERED ACCOUNTING FIRM.)

PROPOSAL 3 — ADVISORY VOTE ON EXECUTIVE COMPENSATION (“SAY-ON-PAY”)

In accordance with Section 14A(a)(1) of the Exchange Act implementing Section 951 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010, we are submitting to our shareholders the opportunity to vote on a non-binding advisory resolution to approve the compensation program for our Named Executive Officers, which is described in the section titled “Executive Compensation” in this Proxy Statement. Accordingly, the following resolution is submitted for a shareholder advisory vote at the 2026 Annual Shareholders’ Meeting:

“RESOLVED, that the shareholders of Mannatech, Incorporated approve, on an advisory basis, the overall compensation of the Company’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K of the regulations promulgated by the SEC, including the section entitled “Executive Compensation,” and the accompanying compensation tables and the corresponding narrative discussion and footnotes set forth in the Proxy Statement for the 2026 Annual Shareholders’ Meeting.”

As described in the section titled “Executive Compensation” our executive compensation program is designed to provide a competitive level of compensation necessary to attract, motivate, and retain talented and experienced executives and to motivate them to achieve short-term and long-term objectives that enhance shareholder value.

This vote is merely advisory and will not be binding upon the Company and the Board. However, the Compensation and Stock Option Plan Committee, which is responsible for designing and administering the Company’s executive compensation program, values constructive dialogue on executive compensation and other important governance topics with the Company’s shareholders and encourages all shareholders to vote their shares on this matter.

Consideration of Director Nominees

Under our Bylaws, the Nominating/Governance and Compliance Committee of our Board of Directors recommends to the Board all candidates for election by our shareholders at each annual meeting of shareholders. Although the Board has not formally established criteria for Board membership, the Board does consider several factors before recommending a candidate for Board membership. These factors include the following:

•

the experience level, mix of skills and other business qualities a potential nominee may possess;

•

the general experience and skill levels of current Board members;

•

the potential nominee’s experience with accounting rules and practices;

•

the verification of background, work, and education of a potential nominee; and

•

other factors as the Nominating/Governance and Compliance Committee may deem in the best interests of our shareholders.

Table of Contents

In addition, the Nominating/Governance and Compliance Committee will recommend director candidates in order to ensure that:

•

a majority of the Board of Directors are “independent” as defined by Nasdaq and SEC rules;

•

each of the Audit, Compensation and Stock Option Plan, and Nominating/Governance and Compliance Committees are comprised entirely of independent directors; and

•

at least one member of the Audit Committee has the experience, education and qualifications necessary to qualify as an “audit committee financial expert” as defined by the SEC.

The Nominating/Governance and Compliance Committee may solicit recommendations for director nominees from any or all of the following sources: non-management directors, executive officers, third-party search firms or any other source it deems appropriate. The Nominating/Governance and Compliance Committee will review and evaluate the qualifications of any proposed director candidate that it is considering or that has been properly recommended to it by a shareholder and conduct inquiries it deems appropriate into the background of these proposed director candidates. When nominating a director for re-election, the Nominating/Governance and Compliance Committee will also consider the director’s past performance on the Board. The Nominating/Governance and Compliance Committee will evaluate all proposed director candidates based on the same criteria, with no regard to the source of the initial recommendation of the proposed director candidate.

The Nominating/Governance and Compliance Committee does not have a formal policy with respect to diversity; however, the Board and the Nominating/Governance and Compliance Committee believe it is important that Board members represent diverse viewpoints. In considering candidates, the Nominating/Governance and Compliance Committee considers the entirety of each candidate’s credentials, including such candidate’s diverse skills, experience and qualifications.

If a shareholder would like our Nominating/Governance and Compliance Committee to consider specific candidates for nomination to the Board, a shareholder should deliver written notice to our Chief Financial Officer at our corporate office, located at 1410 Lakeside Parkway, Suite 200, Flower Mound, Texas 75028, or by fax at (972) 842-9148. As required by our Bylaws, written notice of such proposed candidates for director should be delivered no later than December 31, 2026 to allow the Board time to consider such persons for nomination at our 2027 Annual Shareholders’ Meeting. The written notice should include the candidates’ full name, age, biographical background, and qualifications. If a shareholder intends to present a director nomination at the 2027 Annual Shareholders’ Meeting, the shareholder should follow the procedures described on page 8 of this proxy statement.

Board Leadership Structure and Role in Risk Oversight

Meetings of the Board are presided over by the Chairman of the Board, currently Mr. J. Stanley Fredrick. Our Bylaws do not require that the Chairman be independent, and the Board believes that it is important to retain the discretion and flexibility to determine the appropriate leadership structure for the Company. Currently, the Board believes in the separation of the Chairman and CEO roles. Most important among the considerations to keep these roles separate was that the separation of the Chairman and CEO positions allows our CEO to focus on operational issues and the Chairman to focus on governance and other related issues. Additionally, we believe that the effectiveness of the Board is enhanced by having separate Chairman and CEO positions.

Table of Contents

It is management’s responsibility to manage risk and bring to the Board’s attention any material risks facing the Company. The Board, as a whole and through its committees, regularly reviews various areas of significant risk, and advises and directs management on the scope and implementation of policies, strategic initiatives and other actions designed to mitigate various types of risks. Specific examples of risks primarily overseen by the full Board include competition risks, industry risks, especially those specific to the direct selling channel, economic risks, liquidity risks, business operations risks, cybersecurity and data privacy risks, and risks posed by significant litigation matters.

Our Audit Committee regularly discusses with management and the independent auditors significant financial risk exposure and the processes management has implemented to monitor, control and report such exposures. Specific examples of risks primarily overseen by the Audit Committee include risks related to the preparation of the Company’s financial statements, disclosure controls and procedures, internal controls and procedures required by the Sarbanes-Oxley Act of 2002, accounting, financial and auditing risks, insurance coverage, matters reported to the Audit Committee through our outside internal audit firm and through anonymous reporting procedures.

Our Nominating/Governance and Compliance Committee oversees and discusses with management risk related to governance practices, cybersecurity, compliance and ethics programs for the Company and its independent distributors, regulatory risk, and board composition.

Our Compensation and Stock Option Plan Committee oversees and discusses with management risk related to compensation and retention of executives and high potential employees, and compensation strategies and practices. It also ensures that our compensation programs, including those applicable to our executives, do not encourage excessive risk taking.

Classes of Our Board of Directors

Six directors currently serve on the Board, which is divided into three classes serving staggered three-year terms, which expire on the day of our Annual Shareholders’ Meeting. The Board has determined that four of our directors are independent. The members of each of the classes and the expiration dates of their terms as of April 21, 2026, are as follows:

In making this determination, the Board has concluded that none of these members has a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director.

Mr. Rameson was unable to attend one special Audit Committee meeting and one Science and Marketing Committee Meeting held in November .

These provisions are described in the section titled “Potential Payments Upon Termination or Change in Control” appearing later in this Proxy Statement. In the employment agreements, we have agreed to pay relocation expenses for newly hired executives and allow our executives to participate in our Management Non-Equity Incentive Bonus Plan (as described below). In addition, the employment agreements contain covenants regarding (i) confidentiality and non-disparagement that apply to the executive both during and after employment and (ii) non-competition and non-solicitation that apply to the executive during employment and for one year after termination. Mr. Clavijo is the only Named Executive Officer who has an employment agreement with the Company (the “Clavijo Employment Agreement”).

Non-Equity Incentive Plan

We award annual cash bonuses under our Management Non-Equity Incentive Bonus Plan for achievement of specified performance objectives within a specific performance period, which is typically one year or less. We make awards from an established incentive pool. The Compensation and Stock Option Plan Committee determines the total size of our incentive pool by considering our financial performance. We believe this pool-based bonus system helps foster teamwork and ensures that all executives work collectively to improve our performance.

Shortly after year-end, the Compensation and Stock Option Plan Committee reviewed the performance objectives established under the bonus plan as compared to actual performance delivered by the Company for the fiscal year. Based on the performance criteria, the committee determined that the Company did not achieve the Operating Profit Targets for the year ending December 31, 2025. Consequently, no bonuses were awarded to the senior executive officers under the Management Non-Equity Incentive Bonus Plan.

401(k) Plan

On May 9, 1997, we adopted a 401(k) Pre-tax Savings Plan (the "401(k) Plan"). All full-time employees, including our Named Executive Officers, who have completed three months of service and are at least 21 years of age are eligible to participate in our 401(k) Plan. During 2025, employees were allowed to contribute to our 401(k) Plan up to the maximum annual limit of their current annual compensation, as statutorily prescribed. The 401(k) Plan permits matching employer contributions in the amount of $0.50 for each $1.00 contributed by a participating employee up to a maximum of 6% of the participant’s annual salary. The 401(k) Plan also allows us to make discretionary profit-sharing contributions each year based upon our profit. Employee contributions and our matching contributions are paid to a corporate trustee and are invested as directed by the participant. Our contributions to our 401(k) Plan vest over five years or earlier if the participant retires at age 65, becomes disabled, or dies. Distributions to participants may be made in the case of financial hardship, and distributions may be made in a lump sum. Our 401(k) Plan is intended to qualify under Section 401(a) of the Code, so that contributions made by employees or by us to our 401(k) Plan, and income earned on these contributions, are not taxable to our employees until withdrawn from the 401(k) Plan.

Our Named Executive Officers do not participate in any retirement plans, pension plans (other than the 401(k) Plan) or non-qualified deferred compensation plans.

Potential Payments Upon Termination or Change in Control

The following discussion summarizes our payment obligations to our Named Executive Officers upon termination or change in control assuming such termination or change in control occurred on December 31, 2025:

Options under the Mannatech, Incorporated 2017 Stock Incentive Plan (the “2017 Plan”)

The NEO’s stock option award agreements provide that, upon a termination of employment for “cause” (as defined below), all outstanding options granted under the 2017 Plan, whether vested or unvested, will immediately be forfeited. If, however, an NEO’s employment is terminated for any other reason (other than due to death or “disability” (as defined below)), the NEO may exercise those options that were exercisable immediately prior to his or her termination of employment during the period ending on the earlier of (x) the date that is three months following the date of termination and (y) the expiration date. In the event that a NEO’s employment is terminated due to death or disability, the NEO (or his or her legal representative, executor, administrator, heir or legatee, as the case may be) may exercise those options that were exercisable immediately prior to his or her termination of employment during the period ending on the earlier of (x) the date that is twelve months following the date of termination and (y) the expiration date.

Under the 2017 Plan, the terms “cause” and “disability” have the meanings generally summarized below:

•

“Cause” will be the same as defined in an executive’s employment agreement and absent such agreement, the term “cause” means (i) the commission of a felony or crime involving moral turpitude or other act of willful malfeasance or material fiduciary breach, (ii) conduct tending to bring the Company into substantial public disgrace, or disrepute, (iii) gross negligence or willful misconduct with respect to the Company or (iv) a material violation of state or federal securities laws.

•

“Disability” will be the same as defined in an executive’s employment agreement and absent such agreement, the term “disability” generally means an executive’s inability to substantially perform his or her duties to the Company by reason of a medically determinable physical or mental impairment that is expected to last for a period of six months or longer or to result in death.

Bala Employment Agreement:

Alfredo (Al) Bala retired as the Company’s CEO effective April 1, 2024. Mr. Bala and the Company entered into a Separation Agreement and General Release of Claims. Under the terms of that agreement, Mr. Bala receives severance equal to one year’s salary, in the amount of $460,000, payable over a two-year period. The last payment under that agreement was made to Mr. Bala on April 3, 2026 in the amount of $8,846.15.

Clavijo Employment Agreement:

Under the terms of the Clavijo Employment Agreement, if the Company intends to not renew Mr. Clavijo’s employment agreement, the Company must provide written notice at least 90 days prior to the expiration of the initial term or any renewal term. If the Company exercises its right to not renew the Clavijo Employment Agreement, the Company must pay Mr. Clavijo his base salary for a period of three (3) months following the expiration of the initial term or any renewal term. Additionally, under the Clavijo Employment Agreement, either party may terminate the agreement prior to the expiration of the initial term or any renewal term by providing at least thirty (30) days’ prior written notice of termination for any or no reason, to the other party. If the Company exercises this right, Mr. Clavijo will continue to receive his base salary for the balance of the initial term or any renewal term plus an additional three months following the expiration date. As a condition of receipt of any severance, Mr. Clavijo must execute a release of claims against the Company and its affiliates.

Notwithstanding the statements above, if Mr. Clavijo’s employment is terminated for cause, if he resigns without good reason, or is terminated due to his death, Mr. Clavijo is only entitled to (i) any remaining base salary earned and not yet paid through the termination date; (ii) any annual bonus, or portion thereof, that was earned through the termination date; (iii) all reimbursable expenses due but not yet paid through the termination date; and (iv) all earned or vested benefits (or an amount equivalent to the value of such benefits) payable under our benefit plans or arrangements through the termination date. Under the Clavijo Employment Agreement, “cause”, “good reason” and “disability” has the meanings generally summarized below:

•

“Cause” means (i) we determined that Mr. Clavijo has neglected, failed, or refused to render the services or to perform any other of his duties or obligations under the Clavijo Employment Agreement, (ii) Mr. Clavijo violated any provision or obligation under the Clavijo Employment Agreement, (iii) Mr. Clavijo is indicted for, or plead no contest with respect to, any crime that adversely affected the Company or the utility of Mr. Clavijo’s services to the Company, or (iv) any other act or omission of Mr. Clavijo involving fraud, theft, dishonesty, disloyalty, or illegality that harmed or embarrassed the Company or its affiliates.

•

“Good reason” means (i) any denial of compensation due and owing to Mr. Clavijo under the Clavijo Employment Agreement, (ii) any requirement that Mr. Clavijo be based anywhere other than the DFW Metroplex, except for travel incident to our business, (iii) our demotion of Mr. Clavijo in title or pay, or our removal of a material portion of Mr. Clavijo’s significant duties or responsibilities without Mr. Clavijo’s consent, or (iv) our material breach of the Clavijo Employment Agreement.

•

“Disability” means because of Mr. Clavijo’s physical or mental impairment, he has been substantially unable to perform his duties under the agreement for a continuous period of 180 days, or for 210 days within any one-year period.

The following table shows the potential payments upon Company's termination of Mr. Clavijo’s employment under the circumstances described above or the occurrence of a change in control assuming such termination or change in control occurred on December 31, 2025.

Pursuant to SEC rules, certain equity award adjustments may be required to show compensation actually paid in the event that equity awards are granted, vested or forfeited during the reported year, or there is incremental value or loss on unvested awards. No equity award adjustments are required for the 2023, 2024 and 2025 reported years, and the total amounts reported in the Summary Compensation Table for the PEO and other NEOs for such years is equal to the compensation actually paid for purposes of this disclosure.

The dollar amounts reported in column (d) are the amount of total compensation reported for our non-PEO NEOs, on an average basis, for each corresponding year in the “Total” column of the Summary Compensation Table.

Although the Board does not have a formal policy with respect to related party transactions, in approving or rejecting such proposed transactions, our Audit Committee considers the nature of the related party transaction, the amount and material terms of the transaction, whether the transaction is on terms no less favorable to Mannatech than terms generally available in a similar transaction with an unaffiliated third party, whether the transaction would impair the judgment of a director or executive officer to act in the best interest of Mannatech, and other facts and circumstances available and deemed relevant to our Audit Committee.

REPORT OF THE AUDIT COMMITTEE

Our purpose is to assist the Board in overseeing its financial reporting, internal controls, and audit functions. Larry A. Jobe has been the Audit Committee’s Chairman since February 2007 and is designated by the Board as the financial expert of our Audit Committee. Other members currently include Messrs. Tyler J. Rameson, John A. Seifrick, and Robert Toth. The Board has determined that each of the Audit Committee’s members meet the independence and financial literacy requirements for purposes of serving on such committee under applicable rules of Nasdaq and the SEC. We operate under a written charter adopted by the Board. We review and address the adequacy of our charter on an annual basis. See our Fifth Amended and Restated Charter of the Audit Committee, which is posted on the Company’s corporate website at ir.mannatech.com.

We are responsible for reviewing the Company’s consolidated financial statements, its systems of internal controls, and internal control over financial reporting. The Company’s independent registered public accounting firm is responsible for auditing our consolidated financial statements in accordance with the standards of the Public Company Accounting Oversight Board (United States) (“PCAOB”). Our activities are in no way designed to supersede or alter our responsibilities or the responsibilities of the Company’s independent registered public accounting firm. We assist the Board in fulfilling its responsibilities for oversight of the quality and integrity of the Company’s accounting, auditing, and reporting practices, and such other duties as directed by the Board. Our role does not provide any special assurances with regard to the Company’s consolidated financial statements, nor does it involve a professional evaluation of the quality of audits performed by the Company’s independent registered public accounting firm. We strengthened our ability to assist the Board of Directors, and formed a subcommittee called the Disclosure Committee. The Disclosure Committee is comprised of high-level employees and officers who report to us and the Company’s Chief Executive Officer and Chief Financial Officer. The Disclosure Committee is responsible for reviewing all of the Company’s filings with the SEC. We have furnished the Board with the following report:

We have reviewed and discussed with the Company’s management their audited consolidated financial statements as of and for the year ended December 31, 2025 and the certification process required by the Sarbanes-Oxley Act of 2002. The Company has represented to us that its consolidated financial statements were prepared in accordance with accounting principles generally accepted in the United States of America. We have also discussed the following with BDO USA, P.C., the Company’s independent registered public accounting firm: (i) the auditor’s responsibilities, (ii) any significant issues arising during the audit, and (iii) the matters required to be discussed by the applicable requirements of the PCAOB. We received the written disclosures from BDO USA, P.C. required by Rule 3526 of the PCAOB. We have discussed with the Company’s independent registered public accounting firm the accounting firm’s independence from Company management. In addition, we have discussed the adequacy of the Company’s internal control over financial reporting with the Company’s independent registered public accounting firm and Company management.

Based on the review and discussions referred to above, we recommended to the Board and the Board subsequently approved that the Company’s year-end audited consolidated financial statements be included in the Company’s 2025 Annual Report on its Form 10-K for the year ended December 31, 2025, for filing with the SEC.

FREQUENTLY ASKED QUESTIONS

Our Board of Directors (the “Board”) urges all shareholders to read all of the information included in the proxy materials provided to them. As a courtesy, the Board is providing each shareholder with the following list of frequently asked questions in hopes of eliminating some of the more commonly asked questions and keeping our shareholders informed of the various policies and procedures that must be followed for the 2026 Annual Shareholders’ Meeting.

1.	Why did I receive a Notice of Internet Availability of Proxy Materials this year instead of a paper copy of the proxy materials?

Pursuant to rules promulgated by the SEC, we are providing access to our proxy materials over the Internet. As a result, we are mailing to many of our shareholders a Notice of Internet Availability of Proxy Materials instead of a paper copy of our proxy materials. The notice contains instructions on how to access our proxy materials over the Internet, as well as instructions on how to request a paper copy of our proxy materials by mail.

2.	Why didn’t I receive a Notice of Internet Availability of Proxy Materials?

We are providing some of our shareholders, including those who have previously requested to receive paper copies of the proxy materials, with paper copies of the proxy materials instead of the Notice of Internet Availability of Proxy Materials. In addition, we are providing the Notice of Internet Availability of Proxy Materials by e-mail to those shareholders who have previously elected delivery of the proxy materials electronically. Those shareholders should have received an e-mail containing a link to the website where materials are available.

If you received a paper copy of the proxy materials, you may elect to receive future proxy materials electronically by following the instructions on your proxy card or voting instruction form. Choosing to receive your future proxy materials by e-mail will help us conserve natural resources and reduce the costs of printing and distributing our proxy materials.

3.	How can I access the proxy materials over the Internet?

Your Notice of Internet Availability of Proxy Materials or proxy card will contain instructions on how to view our proxy materials for the 2026 Annual Shareholders’ Meeting on the Internet. Our proxy materials are also available on our company website at ir.mannatech.com.

4.	What is the difference between a proxy-voting card and voting virtually at the virtual-only 2026 Annual Shareholders' Meeting?

A proxy-voting card is mailed to a shareholder. The proxy-voting card gives specific instructions on how to cast a vote prior to our 2026 Annual Shareholders’ Meeting by mail, telephone, or the Internet. The instructions on the proxy-voting card are different depending on whether the shareholder owns shares directly or through a broker. Shareholders should read and follow all of the instructions in their packets to ensure their votes are counted. Shareholders of record who own shares on the close of business on April 6, 2026 and beneficial owners that have obtained a legal proxy from their broker of record who own shares may attend, vote, and submit a question during the virtual-only 2026 Annual Shareholders’ Meeting by visiting www.virtualshareholdermeeting.com/MTEX2026 and using their 16-digit control number to enter the meeting.

5.	What shares owned by a shareholder can be voted either by proxy or at the 2026 Annual Shareholders’ Meeting?

All shares owned directly by a shareholder of record or indirectly as a beneficial owner as of the record date, April 6, 2026, may be voted by the shareholder prior to the meeting by telephone or through the Internet, or by returning a proxy card, without having to login to the webcast. At the 2026 Annual Shareholders’ Meeting, shares may be voted electronically by (i) shareholders of record who are verified with a valid form of identification and (ii) beneficial owners who are verified with a power of attorney from the broker of record giving them authority to vote at the meeting. If a shareholder does not have this information from his or her broker, our Inspector of Elections will not be able to count such shareholder’s vote because the broker may have already cast a vote on such shareholder’s behalf. We strongly recommend that a shareholder read the instructions on the Notice of Internet Availability of Proxy Materials or on the proxy-voting card received by the shareholder or provided by the shareholder’s broker prior to the 2026 Annual Shareholders’ Meeting. A shareholder’s broker can usually mail or fax a shareholder any necessary paperwork prior to the meeting.

6.	How can I vote my shares in person (by attending virtually) and participate at the 2026 Annual Shareholders’ Meeting?

This year’s annual meeting will be held entirely online to allow greater participation. Shareholders may participate in the annual meeting by visiting www.virtualshareholdermeeting.com/MTEX2026. To participate in the 2026 Annual Shareholders’ Meeting, you will need the 16-digit control number included in the Notice of Internet Availability of Proxy Materials or your proxy card. Shares held in your name as the shareholder of record may be voted electronically during the 2026 Annual Shareholders' Meeting. Shares for which you are the beneficial owner but not the shareholder of record also may be voted electronically during the 2026 Annual Shareholders’ Meeting by following the instructions in the voting instruction card provided by your broker, bank or other nominee; however, even if you plan to attend the 2026 Annual Shareholders' Meeting virtually, the Company recommends that you vote your shares in advance, so that your vote will be counted if you later decide not attend the annual meeting.

7.	What is the difference between direct ownership and beneficial ownership?

A shareholder has DIRECT OWNERSHIP over its shares if such shareholder is a holder of record of our common stock, meaning the shareholder either holds stock certificates in the shareholder’s own name or holds book-entry shares registered in the shareholder’s own name. This is evidenced by the shareholder’s receipt of all mailings directly from either our transfer agent, Computershare, or us. A shareholder has BENEFICIAL OWNERSHIP over its shares if such shareholder has delivered its stock certificates to a broker or purchased shares through a broker and receives all of our mailings either from a broker or through a solicitor, which is usually Broadridge Financial Solutions, Inc. As a beneficial owner, the shareholder still owns the shares, but our transfer agent does not have individual shareholders’ names from the brokers. The only information our transfer agent has is the aggregate total number of shares each broker of record holds on behalf of its clients.

8.	How is voting different for direct holders versus beneficial owners?

Our transfer agent has the names of the shareholders who directly hold shares of our common stock, but it does not have any detailed information (such as the individual names or number of shares held) concerning shareholders who own shares through brokers. Only the individual brokers have the detailed information about each shareholder’s beneficial ownership. Each brokerage group is responsible for reporting its clients’ votes to our transfer agent and for providing all mailings to our shareholders who own stock through their brokerage firm. Each brokerage group also has its own set of instructions on how to cast a vote with such brokerage firm.

9.	What does it mean if I received more than one set of materials?

This means your shares are registered with different names. For example, you may own some shares directly as a “holder of record” and other shares through a broker in “street name,” or you may own shares through more than one broker. In these situations, you may receive multiple sets of proxy materials. It is necessary for you either to attend virtually (please note, however, that if a broker or other nominee holds your shares of record and you wish to vote at the meeting, you must obtain from that registered holder a proxy card issued in your name), follow the instructions to vote your shares by telephone or through the Internet provided in the Notice of Internet Availability of Proxy Materials or return a signed, dated and marked proxy card if you received a paper copy of the proxy card. If you vote by mail, make sure you return each proxy card in the return envelope that accompanied that proxy card.

Can I change my proxy vote?

Both direct shareholders and beneficial shareholders can revoke a proxy-vote prior to commencement of the 2026 Annual Shareholders’ Meeting. Attendance at the 2026 Annual Shareholders’ Meeting will not in itself constitute a revocation of a shareholder’s proxy-vote. Generally, shareholders may revoke their proxy-vote by submitting a new proxy-vote with a later date or by voting electronically at our 2026 Annual Shareholders’ Meeting. Shareholders should call the telephone number listed within the shareholder information packets to obtain specific instructions on how to revoke their proxy-vote. Specific instructions on how to revoke a proxy-vote may be different depending on whether a shareholder is a direct shareholder of record or a beneficial shareholder.

Each set of instructions should include the shareholder’s account number and the solicitor’s telephone number and email address. Our Inspector of Elections will only count the verified proxy-votes received from each shareholder and brokerage firm with the latest date. Each share of our common stock represents one vote. Shareholders should call the telephone number provided to them in their shareholder information packets if they are unsure or have any questions. Telephone numbers may be different depending on whether a shareholder is a direct shareholder of record or a beneficial shareholder. The telephone numbers may also be different if a shareholder holds shares at different brokerage firms.

How can I recommend that a person be listed on the ballot as a nominee for the Board?

Shareholder recommendations for nominee(s) for the Board should have been submitted to our Corporate Secretary by March 13, 2026, in order for the Board to have considered such persons for nomination at the 2026 Annual Shareholders’ Meeting. Nominee recommendations should include a candidate’s name, age, biographical information, and qualifications. Upon receipt, our Corporate Secretary forwards the list of nominees to our Nominating/Governance and Compliance Committee. Our Nominating/Governance and Compliance Committee reviews all of the nominees and recommends a list of nominees to the Board. The Board then votes on the nominees. Only the nominees approved by the Board will be listed on our ballot, proxy-voting card, and in our proxy statement on Schedule 14A. To submit recommendations for a nominee to the Board at the 2027 Annual Shareholder Meeting, a shareholder should submit in writing the nominee's information to our Corporate Secretary by not earlier than the opening of business on February 10, 2027, and no later than March 12, 2027. The nomination should be either emailed to legalservices@mannatech.com or mailed to our Corporate Secretary at Mannatech, Incorporated, 1410 Lakeside Parkway, Suite 200, Flower Mound, Texas 75028.

How are the votes counted?

Our Inspector of Elections will be responsible for tabulating all of the votes for the 2026 Annual Shareholders’ Meeting. The presence, either online via the webcast or by proxy-vote, of the holders of at least a majority of shares of our common stock outstanding, as of the record date, is necessary to have a quorum for the 2026 Annual Shareholders’ Meeting. “ABSTAIN” votes and “broker non-votes” will be counted as present for purposes of determining a quorum. A “broker non-vote” occurs when brokers holding shares in “street name” have not received voting instructions from the beneficial owner and either chooses not to vote those shares on a routine matter at the 2026 Annual Shareholders’ Meeting or is not permitted to vote those shares on a non-routine matter.

In tabulating the votes, if a proxy-vote or virtual vote is signed by the shareholder but submitted without providing specific voting instructions, the shareholder’s vote will be counted as a vote “FOR” Proposals 1, 2, and 3. If your shares are held in “street name” and you do not provide specific voting instructions to your broker, then your shares will not be included in the vote for Proposal 1 (Election of Director) or Proposal 3 (“Say-on-Pay” Advisory Vote), but will be voted at the discretion of your broker with respect to Proposal 2 (Ratification of Auditors).

For Proposal 1 (Election of Director) — If a quorum is obtained, our Class III directors will be elected by a plurality of the shares represented, in person (by attending virtually) or by proxy, at the 2026 Annual Shareholders’ Meeting and entitled to vote. This means that the nominees receiving the highest number of affirmative votes at the meeting will be elected as our Class III directors. Votes marked “FOR ALL” will be counted in favor of the nominees. Votes marked “WITHHOLD ALL” will be counted against the nominees. To specify differently, a shareholder must check the “FOR ALL EXCEPT” box and then write the name of the nominee for whom the shareholder wishes to vote against. Votes marked “WITHHOLD ALL” have no effect on the vote since a plurality of the votes is required for the election of the nominees. Shareholders may not abstain from voting with respect to the election of directors.

A shareholder cannot write-in the names of additional nominees when voting by proxy or online during the virtual-only 2026 Annual Shareholders’ Meeting. Shareholders who login to attend the virtual-only 2026 Annual Shareholders’ Meeting may vote on the proposals including the director nominee at www.virtualshareholdermeeting.com/MTEX2026, but shareholders cannot write-in candidates.

For Proposal 2 (Ratification of Auditors) — If a quorum is obtained, and a majority of the shares represented, in person (by attending virtually) or by proxy, at the 2026 Annual Shareholders’ Meeting and entitled to vote, are in favor of Proposal 2, the ratification of the appointment of our independent registered public accounting firm for the year ended December 31, 2026, will be approved. Votes marked “FOR” Proposal 2 will be counted in favor of the ratification of the appointment of our independent registered public accounting firm for the year ended December 31, 2026. An abstention from voting on Proposal 2 will not be voted on that item, although it will be counted for purposes of determining the number of shares represented and entitled to vote. Accordingly, an “ABSTENTION” will have the same effect as a vote “AGAINST” Proposal 2.

For Proposal 3 (“Say-on-Pay” Advisory Vote) — If a quorum is obtained, and a majority of shares represented, in person (by attending virtually) or by proxy, at the 2026 Annual Shareholders’ Meeting and entitled to vote, are in favor of Proposal 3 the current executive compensation program will be approved by shareholders on an advisory basis. Votes marked “FOR” Proposal 3 will be counted in favor of the current executive compensation program. An abstention from voting on Proposal 3 will not be voted on that item, although it will be counted for purposes of determining the number of shares represented and entitled to vote. Accordingly, an “ABSTENTION” will have the same effect as a vote “AGAINST” Proposal 3. “Broker non-votes” are not considered shares entitled to vote for purposes of Proposal 3 and thus will have no effect on the outcome of the approval, on an advisory basis, of our executive compensation program.

18.

What should I do if I never received my proxy materials or if the proxy materials have been lost?

You should contact your broker’s customer service department. The broker should verify that you were a shareholder on the close of business on April 6, 2026 and give you specific instructions on how to obtain new proxy materials and cast a vote. Anyone can view our 2026 proxy statement for the 2026 Annual Shareholders' Meeting by logging onto our corporate website, ir.mannatech.com.
