Item 4.01 Changes in Registrant’s Certifying Accountant.
On June 23, 2025, Aptevo Therapeutics Inc., (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 for the year ending December 31, 2025, effective as of June 23, 2025 (the “Effective Date”).
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 an adverse opinion or a disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles, except that Moss Adams' audit reports on the consolidated financial statements contained an explanatory paragraph regarding a going concern uncertainty.
During the years ended December 31, 2024 and 2023, and the subsequent interim period through the Effective Date, there were no (a) disagreements with Moss Adams on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Moss Adams’ satisfaction, would have caused it to make reference to the subject matter of the disagreement in connection with its reports on the Company’s financial statements, or (b) 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 the date of this Current Report on Form 8-K, 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 provided Moss Adams with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (the “Commission”) and requested that Moss Adams furnish the Company with a letter addressed to the Commission stating whether it agrees with the above statements and, if it does not agree, the respects in which it does not agree. A copy of Moss Adams’ letter to the Commission, dated June 23, 2025, is filed as Exhibit 16.1 to this Form 8-K and is incorporated herein by reference.
