| Item 4.01 | Changes in Registrant’s Certifying Accountant. |
On May 28, 2026, the audit committee (the “Audit Committee”) of the board of directors (the “Board”) of NetScout Systems, Inc. (the “Company”), (i) dismissed PricewaterhouseCoopers LLP (“PwC”) as the Company’s independent registered public accounting firm, and (ii) appointed KPMG LLP (“KPMG”) to serve as the Company’s new independent registered public accounting firm for the fiscal year ending March 31, 2027.
The report of PwC on the consolidated financial statements of the Company for the fiscal years ended March 31, 2026 and 2025 contained no adverse opinion or disclaimer of opinion and was not qualified or modified as to uncertainty, audit scope or accounting principles.
In connection with the Company’s audits for the fiscal years ended March 31, 2026 and 2025 and during the subsequent interim period through May 28, 2026, there were no (i) disagreements (as defined in Item 304(a)(1)(iv) of Regulation S-K and the related instructions thereto) with PwC on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure that would have caused PwC to report the disagreement if it had not been resolved to the satisfaction of PwC or (ii) reportable events (as described in Item 304(a)(1)(v) of Regulation S-K).
The Company provided PwC with a copy of the disclosures in this report prior to filing with the Securities and Exchange Commission (the “Commission”) and requested that PwC provide a letter addressed to the Commission stating whether it agrees with the foregoing statements. A copy of this letter from PwC, dated June 3, 2026, is filed as Exhibit 16.1 to this report.
During the fiscal years ended March 31, 2026 and 2025 and the subsequent interim period through May 28, 2026, neither the Company nor anyone on its behalf consulted with KPMG 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 KPMG 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” or a “reportable event,” as such terms are defined in Regulation S-K Item 304(a)(1)(iv) and (v), respectively.
