Item 4.01. Changes in Registrant’s Certifying Accountant.
On March 4, 2026, the Audit Committee (the “Audit Committee”) of the Board of Directors of Fastly, Inc. (the “Company”) approved the appointment of KPMG LLP (“KPMG”), as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026. As of the date of this report, KPMG is in the process of its standard client evaluation procedures and has not accepted the engagement. During the Company’s two most recent fiscal years (fiscal years ended December 31, 2025 and 2024), respectively, neither the Company nor anyone on its behalf consulted KPMG regarding any of the matters set forth in Item 304(a)(2)(i) or (ii) of Regulation S-K.
Also on March 4, 2026, the Company, with the approval of the Audit Committee, dismissed Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm.
Deloitte’s reports on the Company’s consolidated financial statements for the fiscal years ended December 31, 2025 and 2024, respectively, 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.
During the Company’s fiscal years ended December 31, 2025 and 2024, respectively, there were no (i) disagreements (within the meaning of Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) with Deloitte on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure that, if not resolved to the satisfaction of Deloitte, would have caused Deloitte to make reference thereto in its reports covering the Company’s consolidated financial statements for such periods and (ii) reportable events (as defined in Item 304(a)(1)(v) of Regulation S-K), except for the disclosure of the material weakness in the Company's internal controls over financial reporting as disclosed in Part II, Item 9A of the Company's Annual Report on Form 10-K for the year ended December 31, 2024. As of December 31, 2025, the Company has concluded that this material weakness has been remediated.
This reportable event was discussed among the Audit Committee and Deloitte. Deloitte has been authorized by the Company to respond fully to the inquiries of KPMG, the successor independent registered public accounting firm, concerning this reportable event.
The Company provided Deloitte with a copy of the foregoing disclosures and requested that Deloitte furnish a letter addressed to the SEC stating whether it agrees with the above disclosures and, if not, stating the respects in which it does not agree. A copy of Deloitte’s letter to the SEC, dated March 5, 2026, which confirms agreement with the above disclosures, attached as Exhibit 16.1 hereto.
