Item 4.01. Changes in Registrant’s Certifying Accountant.
On and effective as of June 2, 2025, the Audit Committee (the “Committee”) of the Board of Directors of 8x8, Inc. (the “Company”) dismissed Moss Adams LLP (“Moss Adams”) as the Company’s independent registered public accounting firm and appointed Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, effective the same date.
The audit reports of Moss Adams on the Company’s financial statements as of and for the years ended March 31, 2025 (“fiscal 2025”) and March 31, 2024 (“fiscal 2024”) did not contain any adverse opinion or disclaimer of opinion, nor were they qualified or modified as to uncertainty, audit scope or accounting principles.
During fiscal 2025 and fiscal 2024 and the subsequent interim period through the date of Moss Adams’ dismissal, there were no “disagreements,” as described in Item 304(a)(1)(iv) of Regulation S-K, between the Company and Moss Adams, on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedure, which disagreements, if not resolved to Moss Adams’ satisfaction, would have caused Moss Adams to make reference in connection with its opinion to the subject matter of the disagreement.
During fiscal 2025 and fiscal 2024 and the subsequent interim period through the date of Moss Adams’ dismissal, there were no “reportable events,” as defined 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 and requested that Moss Adams furnish a letter addressed to the U.S. Securities and Exchange Commission stating whether it agrees with the statements contained herein and, if not, stating the respects in which it does not agree. A copy of Moss Adams’ letter, dated as of June 5, 2025, is filed as Exhibit 16.1 to this Current Report on Form 8-K.
During fiscal 2025 and fiscal 2024 and the subsequent interim period through the date of Moss Adams’ dismissal, neither the Company, nor anyone on its behalf, has consulted Grant Thornton regarding: (i) 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, and neither a written report nor oral advice was provided to the Company that Grant Thornton concluded was an important factor considered by the Company in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a “disagreement” (as described in Item 304(a)(1)(iv) of Regulation S-K) or a “reportable event” (as defined in Item 304(a)(1)(v) of Regulation S-K).
