SAN DIEGO and TORONTO, April 23, 2025 (GLOBE NEWSWIRE) — Aptose Biosciences Inc. (“Aptose” or the “Company”) (TSX:APS), a clinical-stage precision oncology company developing a tuspetinib (TUS) based triple drug frontline therapy to treat patients with newly diagnosed acute myeloid leukemia (AML), announces that effective on April 15, 2025, KPMG LLP, the current independent registered public accounting firm of the Company (the “KPMG”), informed the Company that it will not stand for re-appointment for the Company’s 2025 annual audit. The Company anticipates that KPMG will continue to review its quarterly interim financial results through the first two fiscal quarters of 2025. The Company has initiated a process to appoint a new independent registered public accounting firm.
KPMG did not seek the Company’s consent to its decision to not stand for re-appointment as the Company’s independent registered public accounting firm. As a result, neither the Company’s Board of Directors nor the Audit Committee of the Company’s Board of Directors participated in KPMG’s decision.
KPMG issued unqualified reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2024 and 2023. The Company is a “smaller reporting company”, so KPMG was not required to prepare reports on the effectiveness of the Company’s internal control over financial reporting for the years ended December 31, 2024 and 2023.
During the Company’s fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through April 15, 2025, there were no: (1) “disagreements” between the Company and KPMG within the meaning of Item 304(a)(1)(iv) of Regulation S-K on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which disagreements if not resolved to their satisfaction would have caused them to make reference in connection with their opinion to the subject matter of the disagreement, or (2) “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K, except that KPMG communicated to the Company its views regarding the material weakness in its internal control over financial reporting as disclosed in Part II, Item 9A of the Company’s Form 10-K for the fiscal year ended December 31, 2024 pertaining to its accounting for complex financial instruments, specifically with regards to warrants. The Company has authorized KPMG to respond fully to the inquiries of the successor independent registered public accounting firm, once one is engaged.
