Change of Auditor

On October 13, 2025, the audit committee of the Board of Directors (the “Audit Committee”) of Apollomics Inc. (the “Company”) dismissed Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, and then approved Marcum Asia CPAs LLP (“Marcum”) as Grant Thornton’s replacement. Both actions were effective immediately.

Grant Thornton’s reports on the financial statements of the Company for the financial years ended December 31, 2023 and 2024, did not contain any adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles. Furthermore, during the financial years ended December 31, 2023 and 2024, and through October 13, 2025, Grant Thornton and the Company did not have any disagreements on any matters of accounting principles or practices, financial statement disclosure or auditing scope and procedures which, had such disagreements or matters not been resolved to the satisfaction of Grant Thornton, would have caused Grant Thornton to make reference to the subject matter of the disagreement in connection with its reports on the Company’s financial statements for such periods.

There were no reportable events (as that term is described in Item 16F of Form 20-F) during the two financial years ended December 31, 2023 and 2024, through October 13, 2025, except for a material weakness in the Company’s internal control over financial reporting as of December 31, 2023, initially reported in Part II, Item 15 of the Company’s Annual Report on Form 20-F for the fiscal year ended December 31, 2023, which was remediated in during 2024.

The Company provided Grant Thornton with a copy of the forgoing disclosure and requested that Grant Thornton furnish the Company with a letter addressed to the Securities and Exchange Commission stating whether or not Grant Thornton agrees with the above statements and, if not, stating the respects in which Grant Thornton does not agree. A copy of Grant Thornton’s letter, dated October 13, 2025, is filed as Exhibit 16.1 to this Form 6-K.

During the Company’s two most recent financial years, and through October 13, 2025, neither the Company nor anyone acting on the Company’s behalf consulted Marcum with respect to any matters or reportable events set forth in Item 16F of Form 20-F.

Nasdaq Hearing Cancellation and Continued Listing

On October 14, 2025, the Company received a letter from The Nasdaq Stock Market LLC (“Nasdaq”) stating that the Listing Qualifications Staff (the “Staff”) of Nasdaq had determined that the Company is in compliance with Nasdaq’s continued listing requirements. Accordingly, Nasdaq has cancelled its appeal hearing and the Company’s securities will remain listed and continue to trade on The Nasdaq Stock Market. The Company issued a press release concerning its receipt of such letter on October 15, 2025 and has filed such press release as Exhibit 99.1 to this Form 6-K.
