Proxies are solicited to provide all shareholders of record on the Record Date with an opportunity to vote on matters scheduled for the annual meeting and described in these materials. You are a shareholder of record if your shares of USAC common stock and/or preferred stock are held in your name. If you are a beneficial owner of USAC common stock or preferred stock held by a broker, bank or other nominee (i.e., in "street name"), please see the instructions under the following question.

Shares of USAC common stock and preferred stock can only be voted at the annual meeting by proxy or in person if the shareholder is present at the annual meeting, which will be held completely virtually. To ensure your representation at the annual meeting, we recommend you vote by proxy even if you plan to attend the annual meeting. You can always change your vote at the annual meeting if you are a shareholder of record.

Shares of USAC common stock and preferred stock represented by properly executed proxies will be voted by the individuals named on the proxy card in accordance with the shareholder's instructions. Where properly executed proxies are returned to us with no specific instruction as how to vote at the annual meeting, the persons named in the proxy will vote the shares "FOR" the election of each of our seven named director nominees, and "FOR" approval of each of Proposals 2 and 3. If any other matters are properly presented at the annual meeting for action, the persons named in the enclosed proxy and acting thereunder will have the discretion to vote on these matters in accordance with their best judgment. We do not currently expect that any other matters will be properly presented for action at the annual meeting.

You may receive more than one proxy card depending on how your shares are held. For example, you may hold some of your shares individually, some jointly with your spouse, and some in trust for your children. In such case, you will receive three separate proxy cards to vote.

What if My Shares Are Held in Street Name?

If you are the beneficial owner of shares held in "street name" by a broker, your broker, as the record holder of the shares, is required to vote the shares in accordance with your instructions. If you do not give instructions to your broker, your broker may nevertheless vote the shares with respect to discretionary items but will not be permitted to vote your shares with respect to non-discretionary items, pursuant to current industry practice. In the case of non-discretionary items, the shares not voted will be treated as "broker non-votes."

If your shares are held in street name, you will need proof of ownership to be admitted to the annual meeting. A recent brokerage statement or letter from the record holder of your shares are examples of proof of ownership. If you want to vote your shares of USAC common stock or preferred stock held in street name in person at the annual meeting, you will have to get a written proxy in your name from the broker, bank or other nominee who holds your shares.

How Many Shares Must Be Present to Hold the Meeting?

A quorum must be present at the meeting for any business to be conducted. The presence at the meeting, in person or by proxy, of at least a majority of the shares of USAC common stock and preferred stock entitled to vote at the annual meeting as of the Record Date will constitute a quorum. Proxies received but marked as abstentions or broker non-votes will be included in the calculation of the number of shares considered to be present at the meeting.

What if a Quorum Is Not Present at the Meeting?

If a quorum is not present at the scheduled time of the meeting, either the chairperson of the meeting or a majority of the shareholders present or represented by proxy at the meeting may adjourn the meeting until a quorum is present. The time and place of the adjourned meeting will be announced at the time the adjournment is taken, and no other notice will be given unless the meeting is adjourned for 60 days or more. An adjournment will have no effect on the business that may be conducted at the meeting.

Vote Required to Approve Proposals; Effect of Abstentions and Broker Non-Votes

Directors (Proposal 1) are elected by a plurality of the votes cast by the shares entitled to vote at the annual meeting. Votes may be cast FOR or WITHHELD from each nominee. Votes that are withheld and broker non-votes will have no effect on the outcome of the election.

Each of Proposals 2 and 3 will be approved if more votes are cast "FOR" than "AGAINST" the proposal. Abstentions and broker non-votes will have no effect on the outcome of Proposals 2 3.

A "broker non-vote" occurs when a broker or other nominee who holds shares for another person does not vote on a particular proposal because that holder does not have discretionary voting power for the proposal and has not received voting instructions from the beneficial owner of the shares.

May I Revoke My Proxy?

You may revoke your proxy before it is voted by:

If you are the beneficial owner of your shares, you must contact the broker, bank or other nominee holding your shares and follow their instructions to change your vote or revoke your proxy.

How can I obtain a copy of the 2025 Annual Report on Form 10-K?

The Company's 2025 Annual Report on Form 10-K, including financial statements, is available on the internet with this Proxy Statement at www.proxyvote.com. The Form is also available on the Company's website at www.usantimony.com/investors and through the SEC's website at http://www.sec.gov.

Meetings of the Board and Board Member Attendance at Annual Meeting

During the year ended December 31, 2025, the Board held eight regular meetings. Each incumbent director attended at least 75% of the total board and committee meetings on which such person served during this period.

Committees and Committee Charters

The Audit Committee was established in December 2011, the Compensation and Nominating and Corporate Governance Committees were established in 2012, and the Finance Committee was established in 2025.

Audit Committee and Audit Committee Financial Experts

We have a standing Audit Committee and audit committee charter, which complies with Rule 10A-3 of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and the requirements of the NYSE. The Audit Committee consists of Michael A. McManus, Dr. Blaise Aguirre, Joseph A. Carrabba, and Jon R. Marinelli, each of whom is independent (in accordance with Rule 10A-3 of the Exchange Act and the requirements of Section 803A of the NYSE Company Guide) and financially sophisticated (pursuant to the requirements of Section 803B of the NYSE Company Guide). Mr. McManus satisfies the requirement of an "audit committee financial expert" as defined under Item 407(d)(5) of Regulation S-K.

Our Audit Committee meets with our management and our external auditors to review matters affecting financial reporting, the system of internal accounting and financial controls and procedures and the audit procedures and audit plans. Our Audit Committee reviews our significant financial risks and is involved in the appointment of senior financial executives.

Our Audit Committee monitors our audit and the preparation of financial statements and all financial disclosures contained in our SEC filings. Our Audit Committee appoints our external auditors, monitors their qualifications and

independence, and determines the appropriate level of their remuneration. The external auditors report directly to the Audit Committee. Our Audit Committee has the authority to terminate our external auditors' engagement and approve in advance any services to be provided by the external auditors that are not related to the audit.

During the fiscal year ended December 31, 2025, the Audit Committee met four times. A copy of the Audit Committee charter is available on our website at www.usantimony.com.

Audit Committee Report

Our Audit Committee oversees our financial reporting process on behalf of the Board. During 2025, the Committee had four members, each of whom is "independent" as determined under Rule 10A-3 of the Exchange Act and the rules of the NYSE. The Committee operates under a written charter adopted by the Board.

The Committee assists the Board by (1) overseeing the integrity of our financial reporting and internal control, (2) overseeing the independence and performance of our independent auditors, and (3) providing an avenue of communication between management, the independent auditors and the Board.

In the course of providing its oversight responsibilities regarding the 2025 financial statements, the Committee reviewed the 2025 audited financial statements, which appear in the 2025 Annual Report on Form 10-K, with management and our independent auditors. The Committee reviewed accounting principles, practices, and judgments as well as the adequacy and clarity of the notes to the financial statements. The Committee reviewed the independence and performance of the independent auditors who are responsible for expressing an opinion on the conformity of those audited financial statements with accounting principles generally accepted in the United States, and such other matters as required to be communicated by the independent auditors in accordance with Statement of Auditing Standards 61, as superseded by Statement of Auditing Standard 114―the Auditor's Communication With Those Charged With Governance, as modified or supplemented.

The Committee meets with the independent auditors to discuss their audit plans, scope and timing on a regular basis, with or without management present. The Committee has received the written disclosures and the letter from the independent auditors required by applicable requirements of the Public Company Accounting Oversight Board for independent auditor communications with audit committees concerning independence, as may be modified or supplemented.

In reliance on the reviews and discussions referred to above, the Committee recommended to the Board, and the Board has approved, that the audited financial statements be included in the Annual Report to the Securities and Exchange Commission on Form 10-K for the year ended December 31, 2025. The Committee and the Board have also recommended the selection of Assure CPA, LLC as independent auditors for the Company for the fiscal year ending December 31, 2026.

Submitted by the Audit Committee Members

Compensation Committee

Our Compensation Committee is composed of the following directors, each of whom is independent (under Section 803A of the NYSE Company Guide): Joseph A. Carrabba, Dr. Blaise Aguirre, Michael A. McManus, and Jon R. Marinelli.

We have a Compensation Committee charter that complies with the requirements of the NYSE. Our Compensation Committee is responsible for considering and authorizing terms of employment and compensation of executive officers and providing advice on compensation structures in the various jurisdictions in which we operate. Our Chief Executive Officer may not be present during the voting determination or deliberations of his or her compensation; however, our Compensation Committee does consult with our Chief Executive Officer in determining and recommending the compensation of directors and other executive officers.

In addition, our Compensation Committee reviews both our overall salary objectives and significant modifications made to employee benefit plans, including those applicable to executive officers, and proposes awards of stock options and restricted stock units, if any. The Compensation Committee has determined that the Company's compensation

policies and practices for its employees generally, not only with respect to executive officers, are not reasonably likely to encourage behavior that would create an abnormal amount of risk to the Company.

The Compensation Committee does not and cannot delegate its authority to determine director and executive officer compensation.

During the fiscal year ended December 31, 2025, the Compensation Committee met seven times. A copy of the Compensation Committee charter is available on our website at www.usantimony.com.

Nominating and Corporate Governance Committee

Our Nominating and Corporate Governance Committee is composed of the following directors, each of whom is independent as determined under Section 803A of the NYSE Company Guide: Joseph A. Carrabba, Dr. Blaise Aguirre, Michael A. McManus, and General (Ret.) John M. Keane.

Our Nominating and Corporate Governance Committee is responsible for developing our approach to corporate governance issues. The Committee evaluates the qualifications of potential candidates for director positions and recommends to the Board nominees for election at the next annual meeting or any special meeting of shareholders, and any person to be considered to fill a Board vacancy resulting from death, disability, removal, resignation or an increase in Board size. The Committee's charter describes the criteria the Board will assess in connection with the consideration of a candidate, including, but not limited to, the candidate's integrity, reputation, judgment, knowledge, independence, experience, accomplishments, commitment and skills, all in the context of an assessment of the perceived needs of the Board at that time.

The Nominating and Corporate Governance Committee considers diversity as part of its overall selection strategy. In considering diversity of the Board as a criterion for selecting nominees, the Nominating and Corporate Governance Committee takes into account various factors and perspectives, including differences of viewpoint, professional experience, education, personal and professional skills and other individual qualities and attributes that contribute to Board heterogeneity, as well as race, gender and national origin. The Nominating and Corporate Governance Committee also seeks persons with leadership experience in a variety of contexts.

The Committee will consider recommendations for director nominees made by shareholders and others if these individuals meet the criteria set forth in the Committee's charter. For consideration by the Committee, the nominating shareholder or other person must provide the Corporate Secretary's Office with information about the nominee, including a detailed background of the suggested candidate that will demonstrate how the individual meets our director nomination criteria. If a candidate proposed by a shareholder meets the criteria, the individual will be considered on the same basis as other candidates. No shareholder or shareholders holding 5% or more of our outstanding stock, either individually or in aggregate, has recommended a nominee for election to the Board.

All of the seven nominees included on the proxy card accompanying this Proxy Statement were nominated by the Nominating and Corporate Governance Committee and were recommended by our current Board.

During the fiscal year ended December 31, 2025, the Nominating and Corporate Governance Committee met once. A copy of the Nominating and Corporate Governance Committee charter is available on our website at www.usantimony.com.

Board Leadership Structure

The Board has reviewed our current Board leadership structure in light of the composition of the Board, our size, the nature of our business, the regulatory framework under which we operate, our shareholder base, our peer group and other relevant factors. Considering these factors, we determined that a structure with one person as Chairman of the Board and Chief Executive Officer is currently the most appropriate Board leadership structure for the Company based upon the backgrounds and past experience of the individuals. The Board noted the following factors in reaching its determination:

The Board of Directors' Role in Risk Management Oversight

The understanding, identification and management of risk are essential elements for the successful management of the Company. Risk oversight begins with our Board and its committees that address risks inherent in their respective areas of oversight, such as operational, financial, legal, cyber security, and compliance.

The Audit Committee reviews and discusses policies with respect to risk assessment and risk management. The Audit Committee assists the Board by (1) overseeing the integrity of our financial reporting and internal control, (2) overseeing the independence and performance of our independent auditors, and (3) providing an avenue of communication between management, the independent auditors and the Board. Our Nominating and Corporate Governance Committee reviews the risks related to succession planning and the independence of the Board. The Compensation Committee reviews the risks related to our various compensation plans. If a committee is allocated responsibility for examining and analyzing a specific risk, such committee reports on the relevant risk exposure during its regular reports to the entire Board, which facilitates proper risk oversight by the entire Board.

Based on a review of the nature of our operations, we do not believe that any areas of the Company are incentivized to take excessive risks that would likely have a material adverse effect on our operations.

Director Compensation

The following table provides information related to compensation of our non-employee directors for the year ended December 31, 2025:

The fees earned by our directors follow the results of a study prepared by an independent firm using peer data, among other things, to determine market pay for our directors and can be calculated as follows: $65,000 annual retainer for each Board member, $70,000 additional annual retainer for the chairman, $30,000 additional annual retainer for the lead director, which the Board does not have at this time, $20,000, $15,500, $13,500, and $13,500 additional annual retainers for the chairs of the audit, finance, compensation, and nominating and governance committees, respectively, $10,000, $7,500, $7,500, and $5,000 additional annual retainer for each member of the audit, finance, compensation, and nominating and governance committees, respectively, $2,500 for each Board member for attending each Board meeting, $2,000 for the audit committee chair for attending each audit committee meeting, $1,500 for the finance committee chair for attending each finance committee meeting $1,500 for each audit committee member for attending each audit committee meeting, $1,500 for each finance committee member for attending each finance committee meeting, and $1,500 for each compensation and nominating and governance committee chair and member for attending each compensation and nominating and governance committee meeting.

EXECUTIVE COMPENSATION

This section discusses the material components of the executive compensation program for our named executive officers ("NEOs") included in the "Summary Compensation Table" below. We comply with the executive compensation disclosure rules applicable to "smaller reporting companies," as such term is defined in the rules promulgated under the Securities Act, which require compensation disclosure for the last two completed fiscal years for our principal executive officer ("PEO") during the year ended December 31, 2025, the two most highly compensated executive officers other than our principal executive officer who were serving as executive officers as of December 31, 2025 and whose total compensation for 2025 exceeded $100,000, and up to two additional individuals for whom disclosure would have been provided but for the fact that the individual was not serving as an executive officer as of December 31, 2025. These officers are referred to as our named executive officers.

Named Executive Officers

Our NEOs as of December 31, 2025, their ages and positions with the Company are provided in the table below.

Summary Compensation Table

The following table provides a summary of annual compensation of the Company's NEOs for the years ended December 31, 2025 and 2024:

Compensation for all NEOs, including the CEO position, is approved by the Compensation Committee of the Board. The Compensation Committee follows, among other things, the peer group data and advice of an independent compensation consulting firm in reviewing the CEO's compensation recommendations for executives and determining their compensation, and for determining the compensation of the CEO. The material compensation components of NEOs include salary, bonus, and equity awards.

The following table provides information related to outstanding awards held by our NEOs as of December 31, 2025:

Equity Award Timing

The Compensation Committee is responsible for approving stock grants for executive officers. Stock awards are typically granted at the start of employment with the Company and around the end of the calendar year. The purpose of these stock grants is to set performance expectations for the executive officer over the next several years for the financial and operational success of the Company, thereby advancing the Company's interests and the interests of the Company's shareholders. One of the Compensation Committee's considerations when approving stock grants is reviewing the timing of the grant in relation to potential upcoming events, especially if the potential event involves material nonpublic information. The intention of the Compensation Committee is to avoid having disclosure of material nonpublic information affect the value of the stock grant. During the year ended December 31, 2025, stock options were not awarded to a named executive officer in close proximity to a filing with the Securities and Exchange Commission that disclosed material nonpublic information.

Insider Trading Policy

The Company has adopted an Insider Trading Policy that applies to all our directors, officers and employees. We believe our Insider Trading Policy is reasonably designed to deter wrongdoing and promote honest and ethical conduct, to comply with applicable laws, and to provide accountability for adherence to the policy. Our Insider Trading Policy is included in Exhibit 19 of the Company's 2025 Annual Report on Form 10-K and is also available on our web site at www.usantimony.com.

Clawback Policy

The Board has adopted a Clawback Policy covering compensation paid to our executive officers. Under this policy, in the event a restatement of our financial statements is made due to material noncompliance with financial reporting requirements under U.S. securities laws, any performance-based cash compensation paid and any performance-based equity awards granted to such officer with respect to the period covered by the restatement will be recalculated and the board may seek recoupment of any excess compensation.

The Company does not have:

Pay versus Performance

The following table shows the past three fiscal years' total compensation for the NEOs as set forth in the Summary Compensation Table, the total compensation actually paid to the NEOs, the Company's total shareholder return ("TSR"), and the Company's net income (loss).

TSR and net income are two of the factors used to evaluate the performance of our NEOs. In addition, successful completion of various initiatives to improve the Company, such as growing our antimony business and building effective teams, are also factors used to evaluate the performance of our NEOs. Most of these factors span beyond one year. All of these factors have periodic milestones and are used to determine the compensation of our NEOs.

OTHER GOVERNANCE MATTERS

Code of Ethics

We have adopted a corporate Code of Ethics that applies to all of our directors, officers and employees. We believe our Code of Ethics is reasonably designed to deter wrongdoing and promote honest and ethical conduct, to provide full, fair, accurate, timely and understandable disclosure in public reports, to comply with applicable laws, to ensure prompt internal reporting of code violations, and to provide accountability for adherence to the code. Our Code of Ethics provides written standards that are reasonably designed to deter wrongdoing and to promote:

Our Code of Ethics is available on our web site at www.usantimony.com. An electronic copy of the Code of Ethics will be provided to any person without charge upon written request to us at our executive offices: United States Antimony Corporation, 4438 W. Lovers Lane, Unit 100, Dallas, Texas 75209. We intend to disclose any waiver from a provision of our Code of Ethics that applies to any of the following officers: our principal executive officer, principal financial officer ("PFO"), principal accounting officer or controller or persons performing similar functions that relates to any element of our Code of Ethics on our website.

Delinquent Section 16(a) Reports

Section 16(a) of the Exchange Act requires our directors and executive officers and the holders of 10% or more of our common stock to file reports of ownership and changes in ownership with the Securities and Exchange Commission. Officers, directors, and shareholders holding more than 10% of our common stock are required by the regulation to furnish us with copies of all Section 16(a) forms they have filed.

Based solely on our review of copies of Forms 3, 4 and 5 filed with the SEC during or relating to 2025 and written representations provided to the Company, the Company has determined that General (Ret.) John M. Keane and Jon R. Marinelli filed their Forms 3 late in an earlier fiscal period. The Company also determined that Gary C. Evans, Lloyd Joseph Bardswich, Jeffrey R. Fink, and Melissa M. Pagen, filed various Forms 4 late in an earlier fiscal period. All such delinquent reports were subsequently filed.

Compensation Interlocks and Insider Participation

There were no compensation committee or board interlocks among the members of the Board.

CERTAIN RELATIONSHIPS AND RELATED TRANSACTIONS

Since the beginning of the 2025 fiscal year, there were no transactions in which we were a party and in which any director, executive officer or beneficial owner of five percent (5%) or more of any class of our voting securities or relatives of our directors, executive officers or five percent (5%) beneficial owners had a direct or indirect material interest, except as follows: effective March 1, 2026, the Company hired Angel Beltran, the son-in-law of Gary C. Evans, the Company's Chairman and Chief Executive Officer, in a position within the Company's antimony operations and assisting in working on special projects that have been assigned to him. Mr. Beltran, a registered engineer, was previously engaged as a consultant working for various divisions of the Company. Mr. Beltran's compensation is consistent with that of other employees with similar responsibilities and experience.

SECURITY OWNERSHIP OF CERTAIN BENEFICIAL OWNERS AND MANAGEMENT

The following table sets forth information regarding beneficial ownership of our common stock as of April 6, 2026 by (i) each person who is known by us to beneficially own more than 5% of our Series B and C preferred stock or common stock; (ii) each of our named executive officers and directors; and (iii) all of our executive officers and directors as a group. Unless otherwise stated, each person's address is c/o United States Antimony Corporation, 4438 W. Lovers Lane, Unit 100, Dallas, Texas 75209.

Securities Authorized for Issuance under Equity Compensation Plans

The following table summarizes equity compensation plans that were approved by our shareholders and equity compensation plans that were not approved by our shareholders as of December 31, 2025:

PROPOSAL 2 - TO APPROVE AN AMENDMENT TO THE CERTIFICATE OF FORMATION TO INCREASE THE NUMBER OF SHARES AUTHORIZED FOR ISSUANCE BY THE COMPANY

The Board has unanimously adopted and is submitting for shareholder approval an amendment to our Certificate of Formation to increase the number of shares of all classes of capital stock which the Company is authorized to issue from 300,000,000, consisting of 250,000,000 shares of Common Stock, par value $0.01 per share (the "Common Stock") and 50,000,000 shares of Preferred Stock, par value $0.01 per share (the Preferred Stock") to 550,000,000, consisting of 500,000,000 shares of Common Stock and 50,000,000 shares of Preferred Stock (the "Authorized Shares Increase"). The Board believes it is in the best interests of the Company and our shareholders to grant such approval. If the shareholders approve the Authorized Shares Increase, the Board, in its discretion, may elect to affect the Authorized Shares Increase, or the Board may determine in its discretion not to proceed with the Authorized Shares Increase. The Authorized Shares Increase will only be effected after the Board (or a duly authorized committee of the Board) authorizes the filing of a Certificate of Amendment to the Company's Certificate of Formation (the "Authorized Shares Amendment") with the State of Texas and upon the filing and effectiveness of the Authorized Shares Amendment (the "Authorized Shares Effective Time"). The form of the proposed Authorized Shares Amendment is attached to this proxy statement as Appendix A. The Board reserves the right to abandon the Authorized Shares Increase without further action by our shareholders at any time before the Authorized Shares Effective Time, even if shareholders approve such amendment at the annual meeting.

The Authorized Shares Amendment is not intended to modify the rights of existing shareholders in any material respect, nor does it have any affect on the number of authorized shares of the Company's preferred stock. The additional shares of Common Stock to be authorized pursuant to the proposed Authorized Shares Amendment will be identical to the shares of Common Stock currently authorized and outstanding under the Existing Articles, none of which have preemptive or similar rights to acquire the newly authorized shares.

Under the Texas Business Organizations Code, our shareholders are not entitled to appraisal rights with respect to the proposed Authorized Shares Amendment to increase the number of authorized shares of Common Stock, and we will not independently provide shareholders with any such rights.

Reasons for the Authorized Shares Amendment

The Board is proposing the Authorized Shares Amendment to increase the number of authorized shares of our Common Stock from 250,000,000 shares to 500,000,000 shares. Of the 250,000,000 shares of Common Stock that are currently authorized to be issued under the Existing Articles, as of April 6, 2026, 143,039,365 shares are issued and outstanding, and 10,345,906 are reserved for issuance under our existing stock option and equity incentive compensation plans. Other than issuances pursuant to equity incentive plans and except as otherwise disclosed in the Company's SEC filings, as of the date of this proxy statement, we have no current plans, arrangements or understandings regarding the issuance of any additional shares of Common Stock that would be authorized pursuant to this proposal, and there are no negotiations pending with respect to the issuance thereof for any purpose. The Board does not intend to issue any Common Stock except on terms which the Board deems to be in the best interests of the Company and its then existing shareholders. The Board believes that the proposed increase in the number of authorized shares of Common Stock will also benefit the Company by improving our flexibility in considering opportunities that require the issuance of shares of Common Stock in the future which could include acquisitions. The additional authorized shares will be available for issuance from time to time to enable us to respond to future business opportunities requiring the issuance of shares, including the consummation of equity-based financings involving Common Stock or securities convertible into or exercisable for Common Stock ("equity-linked securities") including acquisition or strategic joint venture transactions involving the issuance of Common Stock or equity-linked securities, grants of Common Stock and equity-linked securities to the Company's current and future employees and consultants, or for other general purposes that the Board may deem advisable from time to time. Without an increase in the number of authorized shares of Common Stock, the Company may be constrained in its ability to raise capital in a timely fashion or at all and may lose important business opportunities, which could adversely affect our financial performance and growth.

In determining the size of the proposed authorized share increase, the Board considered a number of factors, including the factors set forth above, the Company's historical issuances of shares and the Company's potential future needs, including that over a number of years the Company may potentially need additional shares in connection with one or more future equity transactions, acquisitions or other strategic transactions and future issuances under equity compensation plans. If the shareholders do not approve this proposal, then the Company will not have needed additional shares available or would be required to seek shareholder approval in connection with any such transaction, which may delay or otherwise have a material adverse effect on such transaction or the Company.

Potential Effects of Not Approving the Authorized Shares Amendment

If the Company's shareholders do not approve the increase in authorized shares of Common Stock, then the Company will not be able to increase the total number of authorized shares of Common Stock from 250,000,000 to 500,000,000 and therefore, the Company could be limited in its ability to use shares of Common Stock for financing, issuing stock options or other general corporate purposes.

Potential Effects of Approving the Authorized Shares Amendment

The proposed increase in the number of authorized shares of Common Stock will not have any immediate effect on the rights of our existing shareholders. However, the Board will have the authority to issue the additional shares of common stock without requiring future shareholder approval of such issuances, except as may be required by applicable law or rules of any stock exchange on which our securities may be listed, including NYSE. The issuance of additional shares of Common Stock may decrease the relative percentage of equity ownership of our existing shareholders, thereby diluting the voting power of their Common Stock. The perception that there might be additional dilution to our existing shareholders may put pressure on our stock price.

While the issuance of additional shares of Common Stock may be deemed to have potential anti-takeover effects, including by delaying or preventing a change in control of the Company through subsequent issuances of these shares and the other reasons set forth above, which, among other things, could include issuances in one or more transactions that would make a change in control of the Company more difficult, and therefore, less likely, this proposal to increase the authorized Common Stock is not prompted by any specific effort of which we are aware to accumulate shares of our Common Stock or obtain control of the Company. A takeover may be beneficial to independent shareholders because, among other reasons, a potential suitor may offer such shareholders a premium for their shares of Common Stock as compared to the then-existing market price. Although the issuance of additional shares of Common Stock could, under certain circumstances, have an anti-takeover effect, this proposal to adopt the Authorized Shares Amendment is not in response to any effort to which the Company is aware to accumulate Common Stock or obtain control of the Company.

The additional authorized shares of Common Stock, if and when issued, would be part of the existing class of Common Stock and would have the same rights and privileges as the shares of Common Stock currently outstanding. Shareholders do not have preemptive rights with respect to our Common Stock. Therefore, should the Board determine to issue additional shares of Common Stock, existing shareholders would not have any preferential rights to purchase such shares in order to maintain their proportionate ownership thereof.

We can provide no assurance that we will be successful in amending our Certificate of Formation to increase the number of shares of Common Stock that are available for issuance, or that the Authorized Shares Amendment will not have an adverse effect on our stock price.

Our directors and executive officers have no substantial interests, directly or indirectly, in the matters set forth in this proposed amendment, except to the extent of their ownership in shares of our Common Stock and securities convertible or exercisable for Common Stock.

Reservation of Right to Abandon the Authorized Shares Increase

The Board reserves the right to abandon the Authorized Shares Increase without further action by our shareholders at any time before the Authorized Shares Effective Time, even if shareholders approve such amendment at the annual meeting. By voting in favor of the Authorized Shares Increase, shareholders are also expressly authorizing the Board to determine not to proceed with, and abandon, the Authorized Shares Increase if it should so decide.

This summary does not purport to be complete and is qualified in its entirety by reference to the Authorized Shares Amendment attached hereto as Appendix A.

Required Vote

Approval of this Proposal 2 requires that the proposal receive "For" votes from the holders of a majority of the shares entitled to vote on the matter at the annual meeting with respect to this Proposal 2. Abstentions and broker non-votes will count towards a quorum, but will have no effect on the outcome of this Proposal 2.

The Board unanimously recommends a vote "FOR" the approval of the Authorized Shares Increase.

PROPOSAL 3 - RATIFICATION OF SELECTION OF INDEPENDENT AUDITOR

The Audit Committee has selected Assure CPA, LLC as our independent auditor for the years ending December 31, 2026 and that selection is being submitted to shareholders for ratification. Although ratification is not required by our bylaws or otherwise, the Audit Committee is submitting the selection of Assure CPA, LLC to our shareholders for ratification as a matter of good corporate practice. If the selection is not ratified, the Audit Committee will consider whether it is appropriate to select another registered public accounting firm. Even if the selection is ratified, the Audit Committee in its discretion may select a different registered public accounting firm at any time during the year if it determines that such a change would be in the best interests of USAC and our shareholders.

Required Vote

Approval of this Proposal 3 requires that the proposal receive "For" votes from the holders of a majority of the shares present in person or represented by proxy and entitled to vote on the matter at the annual meeting that cast votes with respect to this Proposal 3. Abstentions and broker non-votes will count towards a quorum but will have no effect on the outcome of this Proposal 3.

The Board unanimously recommends that you vote "FOR" the ratification of the appointment of Assure CPA, LLC as our independent auditor for the 2026 fiscal year as reflected in this Proposal 3.

Accountant Fees and Services

The following table sets forth the aggregate fees billed to the Company by Assure CPA, LLC for professional services rendered for the fiscal years ended December 31, 2025 and 2024.

The Audit Committee of the Board determined that all of the services performed by Assure CPA, LLC in fiscal year 2025 were not incompatible with Assure CPA, LLC maintaining its independence.

Policy on Audit Committee Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm

Our audit committee's policy is to pre-approve all audit and non-audit services provided by our independent registered public accounting firm. The audit committee pre-approved all audit and tax services provided in 2025 by our independent registered public accounting firm.

HOUSEHOLDING

Shareholders of record who have the same address receive only one copy of the Notice Regarding the Availability of Proxy Materials or the Proxy Statement and Annual Report on Form 10-K, as applicable, unless we receive contrary instructions from one or more of the shareholders. This procedure reduces the Company's printing and mailing costs and the environmental impact of its annual meetings. Shareholders who participate in householding continue to receive separate proxy forms.

Any shareholder who would prefer to have a separate copy of the Notice Regarding the Availability of Proxy Materials, Proxy Statement or Annual Report on Form 10-K delivered to him or her at the shared address for this and future years

may elect to do so by calling 406-827-3523 or by writing to our Corporate Secretary. A copy of the materials will be sent promptly to the shareholder following receipt of a written or oral request by a shareholder to receive a copy of the Notice Regarding the Availability of Proxy Materials, the Proxy Statement or Annual Report on Form 10-K. The foregoing contact information can also be used by shareholders sharing an address to request delivery of a single copy of the Notice Regarding the Availability of Proxy Materials, the Proxy Statement or Annual Report on Form 10-K if they are receiving multiple copies of any of those documents.

SHAREHOLDER PROPOSALS

To be considered for inclusion in the proxy statement relating to our 2027 annual meeting of shareholders, we must receive shareholder proposals (other than for director nominations) no later than December 20, 2026 (120 days before the anniversary of the date notice was mailed for the prior year's meeting), unless we update the deadline in an Exchange Act report. To be considered for presentation at the 2027 annual meeting, although not included in the proxy statement, proposals (including director nominations that are not requested to be included in our proxy statement) must be received no earlier than January 31, 2027 and no later than February 28, 2027, as set forth in Section 2.09 of the bylaws of the Company, provided, that if we move the date of the 2027 meeting more than 30 days before the anniversary date of our 2026 meeting, notice of the proposal must be so delivered not earlier than the close of business on the 120th day prior to such annual meeting and not later than the close of business on the later of the 90th day prior to such annual meeting or the 10th day following the date on which we publicly announce the date of the meeting. Proposals that are not received in a timely manner will not be voted on at the 2027 annual meeting. All shareholder proposals should be marked for the attention of the Secretary of United States Antimony, Inc., 4438 W. Lovers Lane, Unit 100, Dallas, Texas 75209.
