Item 4.01. Changes in Registrant’s Certifying Accountant.

On July 16, 2025 (the “Approval Date”), the Audit Committee (the “Audit Committee”) of the Board of Directors of Maravai LifeSciences Holdings, Inc. (the “Company”) approved the appointment of Deloitte & Touche LLP (“Deloitte”) as the independent registered public accounting firm for the Company for the fiscal year ending December 31, 2025, effective immediately. In addition, on the Approval Date, the Audit Committee approved the dismissal of Ernst & Young LLP (“EY”) as the Company’s independent registered public accounting firm.

EY’s reports on the Company’s consolidated financial statements as of December 31, 2024 and December 31, 2023 and for each of the three years in the period ended December 31, 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. In addition, during the fiscal years ended December 31, 2024 and 2023, as well as through the subsequent interim period through the Approval Date, there were no “disagreements” (as defined in Item 304(a)(1)(iv) of Regulation S-K (“Regulation S-K”) under the Securities Act of 1933, as amended) between the Company and EY with respect to any matter of accounting principles or practices, financial statement disclosure or auditing scope or procedures which, if not resolved to the satisfaction of EY, would have caused EY to make reference to the subject matter of the disagreement in its reports on the Company’s consolidated financial statements covering such periods.

During the fiscal years ended December 31, 2024 and 2023, as well as during the subsequent interim period through the Approval Date, there were no “reportable events” (as defined in Item 304(a)(1)(v) of Regulation S-K), except as described below.

EY’s report on the Company’s internal control over financial reporting as of December 31, 2024, contained an adverse opinion, specifically, that the Company had not maintained effective internal control over financial reporting as of December 31, 2024, due to the effect of material weaknesses identified by management in controls related to revenue and accounts receivable as well as goodwill impairment, as reported by the Company in “Part II, Item 9A. Controls and Procedures” of its Annual Report on Form 10-K for the fiscal year ended December 31, 2024, filed with the Securities and Exchange Commission (the “SEC”) on March 18, 2025. These material weaknesses were discussed by the Audit Committee and EY. The Audit Committee has authorized EY to respond fully to the inquiries of Deloitte concerning such material weaknesses.

In accordance with Item 304(a)(3) of Regulation S-K, the Company provided EY with a copy of this Current Report on Form 8-K and requested that EY furnish the Company with a letter addressed to the SEC stating whether EY agrees with the statements made by the Company herein and, if not, staying the respects in which it does not agree. A copy of EY’s letter dated July 18, 2025 is filed as Exhibit 16.1 to this Current Report on Form 8-K.

During the fiscal years ended December 31, 2024 and 2023, and the subsequent interim period through the Approval Date, the Company did not consult with Deloitte regarding any of the matters or events set forth in Items 304(a)(2)(i) or (ii) of Regulation S-K.
