Item 4.01 Changes in Registrant’s Certifying Accountant.
(a) Dismissal / resignation of previous independent registered public accounting firm.
As previously disclosed, Assure CPA, LLC (“Assure”) served as the independent registered public accounting firm of United States Antimony Corporation (the “Company”). On June 3, 2026, Assure combined its practice with, and was acquired by, Sadler Gibb & Associates, LLC (“Sadler Gibb”) (the “Transaction”). As a result of the Transaction, effective June 3, 2026, Assure effectively resigned and ceased to serve as the Company’s independent registered public accounting firm, and the Company engaged Sadler Gibb as its independent registered public accounting firm. The decision to change the Company’s independent registered public accounting firm was approved by the Audit Committee of the Board of Directors of the Company and concurred in and approved by the Board of Directors, on June 5, 2026.
The audit reports of Assure on the Company’s consolidated financial statements as of and for the fiscal years ended December 31, 2025 and December 31, 2024 did not contain an adverse opinion or a disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles.
During the fiscal years ended 2025 and 2024 and the subsequent interim period through June 3, 2026, there were (i) no disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions) between the Company and Assure on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to Assure’s satisfaction, would have caused Assure to make reference to the subject matter of the disagreement(s) in connection with its reports, and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K.
The Company has provided Assure with a copy of the disclosures in this Current Report on Form 8-K and has requested that Assure furnish a letter addressed to the Securities and Exchange Commission stating whether it agrees with the statements made by the Company in this Item 4.01 and, if not, stating the respects in which it does not agree. A copy of Assure’s letter, dated June 5, 2026, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Engagement of new independent registered public accounting firm.
As described above, effective June 5, 2026, the Company engaged Sadler Gibb as its independent registered public accounting firm for the fiscal year ending December 31, 2026. The engagement of Sadler Gibb was approved by the Audit Committee and the Board of Directors of the Company. In connection with the Transaction, the lead engagement partner and the professional staff principally responsible for the Company’s prior annual audits have continued with Sadler Gibb and remain unchanged.
During the fiscal years ended 2025 and 2024 and the subsequent interim period through June 3, 2026, neither the Company nor anyone acting on its behalf consulted with Sadler Gibb prior to the date of the Transaction regarding (i) the application of accounting principles to a specified transaction, either completed or proposed, or the type of audit opinion that might be rendered on the Company’s financial statements, and neither a written report nor oral advice was provided to the Company by Sadler Gibb that Sadler Gibb concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing or financial reporting issue, or (ii) any matter that was either the subject of a disagreement (within the meaning of Item 304(a)(1)(iv) of Regulation S-K) or a reportable event (within the meaning of Item 304(a)(1)(v) of Regulation S-K).
