Item 4.01 Changes in the Registrant’s Certifying Accountant.
(a) Dismissal of Previous Independent Registered Public Accounting Firm
On March 11, 2025, the Audit Committee (the “Audit Committee”) of the Board of Directors of ArriVent BioPharma, Inc. (the “Company”) approved the dismissal of KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm. The dismissal was not related to any disagreements with KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure.
The reports of KPMG on the financial statements of the Company as of and for the fiscal years ended December 31, 2024 and 2023 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 December 31, 2024 and 2023 and during the interim period through March 11, 2025, there were (a) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between the Company and KPMG on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, any of which, if not resolved to the satisfaction of KPMG, would have caused KPMG to make reference thereto in their reports, and (b) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K except for the material weaknesses in the Company’s internal control over financial reporting as previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2023, filed with the Securities and Exchange Commission (“SEC”) on March 28, 2024 with respect to (i) the review and approval of manual journal entries and (ii) the accounting for certain nonroutine transactions. The material weakness with respect to the accounting for certain nonroutine transactions resulted in the restatement of the Company’s financial statements for the year ended December 31, 2022. These material weaknesses were remediated as of December 31, 2024, as previously reported in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on March 3, 2025. These reportable events were discussed among the Audit Committee and KPMG. KPMG has been authorized by the Company to respond fully to the inquiries of PwC, the successor independent registered public accounting firm, concerning these reportable events.
The Company provided KPMG with a copy of the above disclosures and has requested that KPMG furnish the Company with a letter addressed to the SEC stating whether it agrees with the statements made herein and, if not, stating the respects in which it does not agree. A copy of KPMG’s letter dated March 13, 2025 is filed as Exhibit 16.1 to this Current Report on Form 8-K.
(b) Appointment of New Independent Registered Public Accounting Firm
On March 11, 2025, the Audit Committee appointed PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2025. During the Company’s two most recent fiscal years ended December 31, 2024 and 2023, and during the interim period through March 11, 2025, neither the Company nor anyone on its behalf has consulted with PwC regarding any of the matters described in Items 304(a)(2)(i) and (ii) of Regulation S-K.
