Item 4.01 Changes in Registrant’s Certifying Accountant.

(a) Dismissal of Previous Independent Registered Public Accounting Firm.

On September 4, 2020, the Audit Committee (the “Audit Committee”) of the Board of Directors of Extreme Networks, Inc. (the “Company”) dismissed KPMG LLP (“KPMG”) as the Company’s independent registered public accounting firm, effective immediately. The decision by the Audit Committee was made to reduce ongoing costs related to the Company’s annual audit.

KPMG’s audit reports on the Company’s consolidated financial statements for each of the two most recent fiscal years ended June 30, 2020 and June 30, 2019 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, except as follows:

During the Company’s two most recent fiscal years ended June 30, 2020 and June 30, 2019 and during the subsequent interim period through September 4, 2020, there were (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K with KPMG on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which if not resolved to KPMG’s satisfaction, would have caused KPMG to make reference to the subject matter of the disagreements in its reports on the Company’s consolidated financial statements for such years, and (ii) no “reportable events” as defined in Item 304(a)(1)(v) of Regulation S-K, except for the material weakness in the Company’s internal control over financial reporting as disclosed in the Company’s Quarterly Report on Form 10-Q for the interim period ended March 31, 2019 related to the ineffective design of certain process level controls addressing the accuracy of sales orders entered by the Company.

Pursuant to Item 304(a)(3) of Regulation S-K, the Company provided KPMG 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 has requested that KPMG furnish a letter addressed to the SEC stating whether or not KPMG agrees with the statements above. A copy of KPMG’s letter dated September 11, 2020 is filed as Exhibit 16.1 to this Report.

(b) Appointment of New Independent Registered Public Accounting Firm.

The Audit Committee, on and effective as of September 4, 2020, appointed Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm for the Company’s fiscal year ended June 30, 2021, based on a comparison of costs and considering EY’s experience in the Company’s industry and business model.

During the Company’s two most recent fiscal years ended June 30, 2020 and June 30, 2019 and during the subsequent interim period through September 4, 2020, neither the Company nor anyone acting on its behalf has consulted with EY, 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 EY 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” (as defined in Item 304(a)(1)(iv) of Regulation S-K) or a “reportable event” (as described in Item 304(a)(1)(v) of Regulation S-K).
