Item 4.01 Changes in Registrant’s Certifying Accountant.

On June 3, 2025, Hycroft Mining Holding Corporation (the “Company”) was notified that Moss Adams LLP (“Moss Adams”), the Company’s independent registered public accounting firm, merged with Baker Tilly US, LLP, effective on June 3, 2025. The combined audit practices operate as Baker Tilly US, LLP (“Baker Tilly”). In connection with the notification of the merger, Moss Adams has resigned as the auditors of the Company and the Audit Committee of the Company’s Board of Directors approved the appointment of Baker Tilly, as the successor to Moss Adams, as the Company’s independent registered public accounting firm.

As a result of this merger, the personnel formerly employed by Moss Adams, including the engagement team responsible for the audit of the Company’s financial statements, will continue to work on the Company’s audit.

The audit reports of Moss Adams on the Company’s consolidated financial statements as of and for the years ended December 31, 2024 and 2023 did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope, or accounting principles, except that Moss Adams’ audit report on the Company’s consolidated financial statements as of and for the year ended December 31, 2024 contained an explanatory paragraph regarding a going concern uncertainty.

During the Company’s two most recent fiscal years and through June 3, 2025, there were (i) no disagreements with Moss Adams on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of Moss Adams, would have caused it to make reference thereto in its reports on the Company’s consolidated financial statements as of and for such years; and (ii) no “reportable events” requiring disclosure pursuant to Item 304(a)(1)(v) of Regulation S-K.

During the years ended December 31, 2024 and 2023, and the subsequent interim period through June 3, 2025, neither the Company, nor anyone on its behalf, consulted with Baker Tilly regarding: (i) either 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; or (ii) any matter that was either the subject of a “disagreement,” as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions to that item, or a “reportable event,” as described in Item 304(a)(1)(v) of Regulation S-K.

The Company has provided Moss Adams with a copy of the disclosures in this Form 8-K and requested that Moss Adams furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not it agrees with the above statements. A copy of such letter, dated June 6, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
