Item 4.01 Changes in Registrant’s Certifying Accountant.

(a)Dismissal of Independent Registered Public Accounting Firm

On May 28, 2026 (the “Effective Date”), MaxLinear, Inc. (the “Company”) dismissed Grant Thornton LLP (“Grant Thornton”) as the Company’s independent registered public accounting firm, effective immediately. The dismissal of Grant Thornton has been approved by the audit committee of the board of directors of the Company (the “Audit Committee”).

Grant Thornton’s report on the Company’s consolidated financial statements for each of the fiscal years ended December 31, 2025 and December 31, 2024 did not contain any 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 December 31, 2024 and the subsequent interim period through to the Effective Date, there have been (i) no disagreements with Grant Thornton on any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures, which disagreements, if not resolved to Grant Thornton’s satisfaction, would have caused Grant Thornton to make reference to the subject matter of the disagreements in connection with its report, and (ii) no “reportable events” (as that term is defined in Item 304(a)(1)(v) of Regulations S-K).

The Company provided Grant Thornton with a copy of this Current Report on Form 8-K prior to its filing with the Securities and Exchange Commission (“SEC”) and requested that Grant Thornton furnish it with a letter addressed to the SEC stating whether or not it agrees with the above statements. A copy of Grant Thornton’s letter, dated June 1, 2026, is filed as Exhibit 16.1 to this Current Report on Form 8-K.

(b)Engagement of New Independent Registered Public Accounting Firm

The Audit Committee also approved the engagement of KPMG LLP (“KPMG”) to serve as the Company’s independent registered public accounting firm and appointed KPMG as the Company’s independent registered public accounting firm for the fiscal year ending December 31, 2026.

During the Company’s fiscal years ended December 31, 2025 and 2024, and the subsequent interim period through May 28, 2026, neither the Company nor anyone acting on its behalf has 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 consolidated 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, (ii) any matter that was the subject of a disagreement within the meaning of Item 304(a)(1)(iv) of Regulation S-K, or (iii) any reportable event within the meaning of Item 304(a)(1)(v) of Regulation S-K.
