Item 2.02. Results of Operations and Financial Condition.

On August 11, 2025, Maravai LifeSciences Holdings, Inc. issued a press release announcing its financial results for the second quarter of 2025. The full text of the press release issued in connection with the announcement is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information in Item 2.02 of this Form 8-K and the Exhibit 99.1 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 2.05. Costs Associated with Exit or Disposal Activities.

On August 11, 2025, the Company announced an organizational restructuring, including a workforce reduction, to reduce operating costs. The workforce reduction, which is being implemented as part of a strategic cost-reduction initiative, was committed to by management on August 8, 2025 and is expected to impact approximately 25% of the Company’s workforce. In connection with the workforce reduction, the Company currently estimates it will incur restructuring and related costs in the range of $8.0 million to $9.0 million, consisting primarily of employee severance and benefits costs, the majority of which the Company expects to recognize in the second half of 2025.

The estimated range of costs that the Company expects to incur in connection with the workforce reduction represents the Company’s current estimate only and is subject to a number of assumptions and actual results may differ materially from the estimated range. The Company may incur additional costs not currently contemplated due to events that may occur as a result of, or in connection with, the workforce reduction.

Item 5.02. Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On August 7, 2025, the Company’s Board of Directors eliminated the positions held by Rebecca Buzzeo, Executive Vice President and Chief Commercial Officer of the Company, and Pete Leddy, Ph.D., Executive Vice President and Chief Administrative Officer of the Company. As a result, Ms. Buzzeo’s last day of employment with the Company is expected to be September 2, 2025, and Dr. Leddy’s last day of employment with the Company is expected to be October 2, 2025.

Both Ms. Buzzeo’s and Dr. Leddy’s departures from the Company constitute a termination by the Company without “cause” under their respective Amended and Restated Employment Agreements, effective as of May 8, 2023, and each of Ms. Buzzeo and Dr. Leddy will be entitled to receive

Item 2.02. Results of Operations and Financial Condition.

On March 18, 2025, Maravai LifeSciences Holdings, Inc. issued a press release announcing its financial results for the fourth quarter and full fiscal year ended December 31, 2024. The press release is furnished as Exhibit 99.1 to this Current Report on Form 8-K.

The information in Item 2.02 of this Form 8-K and the Exhibit 99.1 attached hereto shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended (the “Securities Act”), or the Exchange Act, except as expressly set forth by specific reference in such filing.

Item 4.02. Non-Reliance on Previously Issued Financial Statements or a Related Audit Report or Completed Interim Review.

(a) On March 17, 2025, the Audit Committee of the Board of Directors of the Company (the “Audit Committee”) concluded that the Company’s interim financial statements and related disclosures included in the Company’s Quarterly Reports on Form 10-Q for the fiscal quarters ended June 30, 2024 (“Q2 2024”), and September 30, 2024 (“Q3 2024”), and as of and for the interim periods ended June 30, 2024, and September 30, 2024 (collectively, the “Restated Periods”), included in its Quarterly Reports for Q2 2024 and Q3 2024, should no longer be relied upon and are being restated (the “Restatement”) as set forth in the Company’s consolidated financial statements included with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 (the “2024 Form 10-K”), which the Company expects to file concurrently with this this Form 8-K.

The Restatement primarily corrects an error identified during the year-end financial close process with respect to revenue recognition associated with a single shipment that resulted in approximately $3.9 million in revenue being recorded in the final week of the second quarter of 2024 upon shipment when it should have been recorded in the first week of the third quarter of 2024 upon receipt by the customer. The effects of the Restatement on the consolidated financial statements for Restated Periods are set forth in Note 18 to the Company’s consolidated financial statements included with the 2024 Form 10-K being filed concurrently with this Form 8-K.

In connection with these matters, the Company concluded that, as of December 31, 2024, the Company’s disclosure controls and procedures were not effective at a reasonable assurance level and its internal control over financial reporting was ineffective, due to the material weaknesses in internal control over financial reporting described in Part II, Item 9A of the 2024 Form 10-K being filed concurrently with this Form 8-K.
