Item 4.01 Changes in Registrant’s Certifying Accountant
On, and effective as of, August 21, 2026, the Audit Committee (the “Audit Committee”) of the Board of Directors of Extreme Networks, Inc. (the “Company”) approved the dismissal of Grant Thornton LLP (“GT”) as the Company’s independent registered public accounting firm. Also on, and effective as of, August 21, 2026, the Audit Committee approved the appointment of Deloitte & Touche LLP (“Deloitte”) as the Company’s independent registered public accounting firm for the Company’s fiscal year ending June 30, 2027, and related interim periods.
GT’s reports on the Company’s consolidated financial statements for the fiscal years ended June 30, 2026, and June 30, 2025, 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 June 30, 2026, and June 30, 2025, and during the subsequent interim period through August 21, 2026, there were (i) no “disagreements” (within the meaning of Item 304(a)(1)(iv) of Regulation S-K) between the Company and GT on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedures, which if not resolved to GT’s satisfaction, would have caused GT to make reference to the subject matter of the disagreements in its reports, and (ii) no “reportable events” (within the meaning of Item 304(a)(1)(v) of Regulation S-K).
Pursuant to Item 304(a)(3) of Regulation S-K, the Company provided GT with a copy of the disclosures in this Current Report on Form 8-K (this “Report”) prior to filing this Report with the Securities and Exchange Commission (the “SEC”). The Company requested that GT furnish a letter addressed to the SEC stating whether GT agrees with the statements set forth above. A copy of GT’s letter dated August 26, 2026, is filed as Exhibit 16.1 to this Report.
During the Company’s two most recent fiscal years ended June 30, 2026, and June 30, 2025, and during the subsequent interim period through August 21, 2026, neither the Company nor anyone acting on its behalf consulted Deloitte regarding either (i) the application of accounting principles to a specific transaction, completed or proposed, or the type of audit opinion that might be rendered on the Company’s consolidated financial statements, and neither a written report nor oral advice was provided to the Company that Deloitte concluded was an important factor considered by the Company in reaching a decision as to any accounting, auditing, or financial reporting issue, or (ii) any matter that was either the subject of a “disagreement” (within the meaning of Item 304(a)(1)(iv) of Regulation S-K) or a “reportable event” (within the meaning of Item 304(a)(1)(v) of Regulation S-K).
