TABLE OF CONTENTS

COMMONLY ASKED QUESTIONS AND ANSWERS ABOUT THE ANNUAL MEETING

Q: Why did I receive these proxy materials?

The Board of Directors (the “Board”) is soliciting your proxy to vote at the 2025 Annual Meeting of Shareholders (or at any postponement or adjournment thereof) (“Annual Meeting”) of Maravai LifeSciences Holdings, Inc. (“Maravai,” the “Company,” “we,” “us” or “our”). Holders of shares of our Class A common stock, par value $0.01 per share (“Class A common stock”), or our Class B common stock, par value $0.01 per share (“Class B common stock” and, together with the Class A common stock, the “common stock”), as of the record date, March 24, 2025 (the “Record Date”), are entitled to notice of and to vote at the Annual Meeting. You should review this entire proxy statement carefully as it gives important information about the proposals that will be voted on at the Annual Meeting, as well as other important information about Maravai.

Householding. The Securities and Exchange Commission’s (“SEC”) rules permit us to send a single set of proxy materials to shareholders with multiple accounts registered with the same tax identification number or which share the same last name and household mailing address, unless we received contrary instructions from the impacted shareholders prior to the mailing date. This procedure is referred to as “householding.” Each registered shareholder will, however, continue to receive a separate proxy card. We agree to deliver promptly, upon written or oral request, a separate copy of the proxy materials to any shareholder to which a single copy of those documents was delivered. If you prefer to receive separate copies of the annual meeting materials, you may write or call us at the following address or phone number, and we will promptly deliver them.

c/o General Counsel and Secretary

Phone: (858) 988-5919

A number of banks and brokers have also instituted householding. They will have their own procedures for shareholders who wish to receive individual copies of the proxy materials instead of a combined mailing. If you are a beneficial shareholder and hold your shares in “street name,” please contact your bank or broker regarding combined mailings.

Q: Who will be entitled to vote?

Shareholders who own shares of our Class A common stock or Class B common stock as of the Record Date are entitled to vote at the Annual Meeting. As of the Record Date, Maravai had 143,958,169 shares of Class A common stock and 110,684,080 shares of Class B common stock outstanding. Holders of shares of Class A common stock and holders of shares of Class B common stock are each entitled to one vote per share, voting together as a single class on all matters to be considered at the Annual Meeting. Cumulative voting is not permitted with respect to the election of directors or any other matter to be considered at the Annual Meeting.

Q: What will I be voting on?

You will be voting on:

Q: How do I cast my vote?

Registered Shareholders. If you hold shares registered with our transfer agent in your own name, you are a registered shareholder. Whether or not you plan to attend the Annual Meeting, we urge you to vote your shares as soon as possible to ensure your representation at the Annual Meeting. You may still attend the Annual Meeting and vote your shares electronically during the Annual Meeting even if you have already voted by another method.

You can vote by proxy before the Annual Meeting in the following ways:

Proxies submitted over the Internet, by telephone or by mail must be received prior to the commencement of the Annual Meeting at 2:30 p.m. Pacific Time on May 22, 2025.

Please be sure to follow the subsequent instructions that will be delivered to you via email. Only one person will be able to log in with that unique control number at any time.

Beneficial Shareholders. If you hold your shares through a bank, broker, trustee or other nominee in “street” name, you are a beneficial shareholder, and you will receive a voting instruction form from your broker, bank or other nominee seeking instructions from you on how to vote the shares you hold as a beneficial shareholder. To vote during the meeting, you must first obtain a legal proxy from your bank, broker or other nominee and deliver that legal proxy to our Corporate Secretary sufficiently in advance of the Annual Meeting, as well as follow the instructions you receive via email after registering to attend the Annual Meeting online.

Q: Can I access the proxy materials electronically?

Yes. Your proxy card or voting instruction form will contain instructions on how to:

Our proxy materials are also available at www.proxydocs.com/MRVI.

Instead of receiving future copies of our proxy statement and annual reports by mail, shareholders of record and most beneficial owners can elect to receive an email that will provide an electronic link to these documents. Your election to receive future proxy materials by email will remain in effect until you revoke it.

Q: How may I change or revoke my proxy?

Registered Shareholders. Registered shareholders may change a properly executed proxy at any time before its exercise at the Annual Meeting by:

Beneficial Shareholders. Beneficial shareholders should contact their broker, trustee or nominee for instructions on how to change their vote.

Q: How can I attend the Annual Meeting?

The Annual Meeting is being held as a virtual only meeting.

Registered Shareholders. If you are a registered shareholder as of the Record Date, you may attend, vote and ask questions virtually at the meeting by registering in advance of the meeting at www.proxydocs.com/MRVI using your unique control number included on your proxy card that accompanies your proxy materials. Upon completing your registration, you will receive further instructions via email, including information about your unique link that will allow you to attend the Annual Meeting and to vote and submit questions during the Annual Meeting.

Beneficial Shareholders. If you are a beneficial shareholder holding your shares through a bank, broker or other nominee in “street name” as of the Record Date, you may gain access to the meeting, including for the purpose of asking questions virtually at the meeting, by registering in advance at www.proxydocs.com/MRVI using the control number found on the voting instruction card provided by your broker, bank or other nominee. In order to vote your shares electronically at the Annual Meeting, in addition to registering in advance, you will also need to obtain a valid legal proxy from your bank, broker or other nominee reflecting the number of shares of our Class A common stock or Class B common stock you held as of the close of business on the Record Date and e-mail the legal proxy to [email protected] with the subject line “Maravai Legal Proxy” by 12:00 p.m., Pacific Time, on May 21, 2025. If you do not plan to vote your shares electronically at the meeting, you may vote your shares by following the voting instructions provided by your bank, broker or other nominee.

Online access to the audio webcast of the Annual Meeting will begin at approximately 2:15 p.m., Pacific Time, on May 22, 2025, pursuant to the unique access instructions you receive following your advance registration at www.proxydocs.com/MRVI. If you have questions during the live audio webcast of the Annual Meeting, you may type them into the dialog box provided at any point during the meeting (until the floor is closed to questions). Shareholder questions or comments are welcome, but we will only answer questions pertinent to the matters being voted upon at the Annual Meeting, subject to time constraints. Questions regarding personal matters and statements of advocacy are not pertinent to Annual Meeting matters and therefore will not be addressed. Questions or comments that are substantially similar may be grouped and answered together to avoid repetition.

Only shareholders as of the Record Date that have registered to attend the meeting may listen to the Annual Meeting and ask questions at the meeting.

An audio replay of the Annual Meeting will be available at https://investors.maravai.com shortly after the completion of the meeting.

Q: What if I run into technical issues while trying to access the Annual Meeting?

The virtual meeting platform is supported across browsers and devices running the most updated version of applicable software and plug-ins. Participants should give themselves plenty of time to log in and ensure they have a strong internet connection, and they can hear streaming audio prior to the start of the meeting. Each participant that has registered to attend the meeting will receive a reminder email at approximately 1:30 p.m., Pacific Time, on the day of the meeting, which is one hour prior to the meeting start time. The reminder email will include an FAQ link where you will find contact information for the Mediant Help Desk. The Mediant Help Desk will be available starting at 1:30 p.m., Pacific Time, until the end of the meeting.

Q: Why is the Annual Meeting virtual only?

We successfully held virtual only annual meetings in past years and believe that this meeting format provides ease of access, real-time communication, and cost savings for our shareholders and the Company. Hosting a virtual meeting makes it easy for our shareholders to attend and participate in the Annual Meeting from any location around the world and provides those of our shareholders who would otherwise not be able to attend the Annual Meeting the opportunity to do so.

Q: What is the voting requirement to approve each of the proposals, and how are the votes counted?

PROPOSAL 1—ELECTION OF DIRECTORS

A plurality of the votes cast by the shares of our common stock present in person or represented by proxy at the meeting and entitled to vote thereon is required to elect each nominee named herein. This means that the four nominees receiving the highest number of “FOR” votes cast at the Annual Meeting will be elected, even if those votes do not constitute a majority of the votes cast. Votes that are “WITHHELD” with respect to one or more nominees will result in the respective nominee receiving fewer votes, but they will not count as votes against a nominee and will have no effect on the outcome of the election of those nominees because directors are elected by a plurality of the votes cast the Annual Meeting.

If you are a beneficial (or “street name”) shareholder, your bank or broker is not permitted to vote your shares on this proposal if voting instructions are not received from you (this is commonly referred to as a “broker non-vote”). Broker non-votes are not considered votes cast and, therefore, will not impact the election of the director nominees.

PROPOSAL 2—RATIFICATION OF THE APPOINTMENT OF THE INDEPENDENT REGISTERED ACCOUNTING FIRM

The affirmative vote of a majority of the voting power of the shares of our common stock present or represented by proxy at the meeting and entitled to vote thereon is required to approve the ratification of Ernst & Young LLP as our independent registered accounting firm. Abstentions will be counted as present and entitled to vote on the proposal and will therefore have the effect of a vote against this proposal. Since this is a “routine” matter (as described below), we do not expect there will be any broker non-votes with respect to the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2025.

4

PROPOSAL 3—ADVISORY VOTE ON THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS

The affirmative vote of a majority of the voting power of the shares of our common stock present or represented by proxy at the meeting and entitled to vote thereon is required to approve, on a non-binding advisory basis, the compensation of our named executive officers as disclosed in this proxy statement (commonly known as a “say-on-pay” proposal). Abstentions will be counted as present and entitled to vote and therefore will have the same effect as a vote against this proposal. The say-on-pay proposal is not considered a “routine” matter, and therefore, if you are a beneficial (or “street name”) shareholder and your bank, broker or other nominee does not receive instructions from you, they may not vote your shares on your behalf (a broker non-vote). Broker non-votes are not considered entitled to vote on this proposal and, therefore, will have no effect on the approval of this proposal.

Q: When will the results of the vote be announced?

The preliminary voting results will be announced at the end of the Annual Meeting. The final voting results will be published in a Current Report on Form 8-K filed with the SEC within four business days of the Annual Meeting.

Q: What is the deadline for submitting a shareholder proposal or director nomination for the 2026 Annual Meeting?

Shareholder proposals pursuant to SEC Rule 14a-8 for inclusion in Maravai’s proxy statement and form of proxy for our 2026 Annual Meeting of Shareholders must be received by the Corporate Secretary at our principal executive offices at 10770 Wateridge Circle Suite 200, San Diego, California 92121, no later than December 19, 2025.

Shareholders wishing to make a director nomination or submit a proposal at our 2026 Annual Meeting of Shareholders (but not include it in Maravai’s proxy materials for such meeting) must deliver written notice of such nomination or proposal to the Corporate Secretary at Maravai’s principal executive offices no later than the close of business on February 21, 2026, and not earlier than the close of business on January 22, 2026, assuming the date of our 2026 Annual Meeting of Shareholders is no more than 30 days before or after the anniversary of this year’s Annual Meeting. If that is not the case, then such written notice must be delivered by the later of the tenth day following the day on which Maravai publicly releases the date of our 2026 Annual Meeting of Shareholders or the date which is ninety days prior to the date of such meeting. Any such nomination or proposal must also comply with the requirements specified in Maravai’s Amended and Restated Bylaws (“Bylaws”).

In addition to satisfying the requirements under our Bylaws, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees, other than Maravai’s nominees, must provide written notice that sets forth all of the information required by Rule 14a-19 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), which written notice must be postmarked or transmitted electronically to the Corporate Secretary at our principal executive offices at 10770 Wateridge Circle Suite 200, San Diego, California 92121, no later than March 23, 2026. However, if the date of our 2026 Annual Meeting of Shareholders is changed by more than 30 days from May 22, 2026, then written notice must be provided by the later of the 60th day prior to the date of our 2026 Annual Meeting of Shareholders and the 10th day following the day on which public announcement of the date of our 2026 Annual Meeting of Shareholders is first made by us.

Q: If I am a beneficial shareholder and hold my shares in “street name,” how will my shares be voted if I don’t provide voting instructions?

Current New York Stock Exchange rules allow brokers to vote shares on certain “routine” matters for which their customers do not provide voting instructions. If you are a beneficial shareholder and own shares in “street

5

name” through a broker, bank, or other nominee, the ratification of the appointment of Ernst & Young LLP as our independent registered public accounting firm for the year ending December 31, 2025 (Proposal 2) is considered a “routine” matter on which your broker may use its discretion to vote your shares without your instructions. The election of directors (Proposal 1) and the advisory vote on executive compensation (Proposal 3) are not routine proposals; therefore, your broker will be unable to vote your shares on these proposals if you do not instruct your broker how to vote, which is referred to as a “broker non-vote.” Broker non-votes will have no effect on the outcome of the election of the director nominees or the advisory vote on executive compensation.

BOARD OF DIRECTORS AND CORPORATE GOVERNANCE

Board Structure and Composition

Our business and affairs are managed under the direction of the Board, which is currently comprised of eleven directors. Our certificate of incorporation (our “Certificate”) provides that the authorized number of directors may be changed only by resolution of the Board. Our Certificate also provides that the Board will be divided into three classes of directors, with the classes as nearly equal in number as possible. At each annual meeting of shareholders, a class of directors will be elected for a three-year term to succeed the class whose term is then expiring.

The following table sets forth the director class, name, age as of March 24, 2025, and other information for each member of the Board:

We believe that in order for the Board to effectively guide us to long-term sustainable, dependable performance, it should be comprised of individuals with sophistication and experience in the many disciplines that impact our business. In order to best serve our shareholders, we seek to have a Board, as a whole, that is competent in key corporate disciplines, including accounting and financial acumen, business judgment, crisis management, governance, leadership, people management, risk management, social responsibility and reputational issues, strategy and strategic planning. Additionally, we desire that the Board have specific knowledge related to our industry.

The Nominating, Governance and Risk Committee believes that all directors must, at a minimum, meet the criteria set forth in the Company’s Code of Ethics and its Corporate Governance Guidelines, which specify, among other things, that the Nominating, Governance and Risk Committee will consider criteria such as independence, skills, and experience in the context of the needs of the Board. When considering the selection of director nominees, the Nominating, Governance and Risk Committee considers individuals with a range of backgrounds, viewpoints, accomplishments, cultural background and professional expertise, among other factors, that, when considered as a group, provide a sufficient mix of perspectives to allow the Board to best fulfill its responsibilities to the long-term interests of our shareholders. Consistent with this philosophy, in addition to the factors described below, the Nominating, Governance and Risk Committee considers nominees who have the variety of skill sets, experiences and personal backgrounds that will allow our directors to provide the diversity of thought that is critical the Board’s decision-making and oversight process. The Nominating, Governance and Risk Committee also will consider a combination of factors for each director, including (a) the nominee’s ability to represent all shareholders without a conflict of interest, (b) the nominee’s ability to work in and promote a productive environment, (c) whether the nominee has sufficient time and willingness to fulfill the substantial duties and responsibilities of a director, (d) whether the nominee has demonstrated the high level of character, ethics and integrity expected by the Company, (e) whether the nominee possesses the broad professional and

7

leadership experience and skills necessary to effectively respond to the complex issues encountered by a publicly-traded company, (f) the nominee’s ability to apply sound and independent business judgment and (g) differences in background, qualifications and personal characteristics.

The Nominating, Governance and Risk Committee has determined that all of our directors meet the criteria and qualifications set forth in the Company’s Code of Ethics and its Corporate Governance Guidelines and the criteria set forth above for director nominees. Moreover, each director possesses the following critical personal qualities and attributes that we believe are essential for the proper functioning of the Board to allow it to fulfill its duties for our shareholders: accountability, ethical leadership, governance, integrity, risk management, and sound business judgment. In addition, our directors have the confidence to assess and challenge the way things are done and recommend alternative solutions, a keen awareness of our business and social realities of the environment in which we operate, the independence and high-performance standards necessary to fulfill the Board’s oversight function, and the humility, professional maturity, and style to interface openly and constructively with other directors. Finally, the director biographies below include a non-exclusive list of other key experiences and qualifications that further qualify the individual to serve on the Board. We believe these collective qualities, skills, experiences and attributes are essential to the Board’s ability to exercise its oversight function for Maravai and its shareholders and to guide us to long-term sustainable, dependable performance.

Subject to any earlier resignation or removal in accordance with the terms of our Certificate, Bylaws or the Director Nomination Agreement (as defined and discussed below) with Maravai Life Sciences Holdings, LLC (“MLSH 1”), Maravai Life Sciences Holdings 2, LLC (“MLSH 2”), GTCR Fund XI/C LP, GTCR Fund XI/B LP, GTCR Co-Invest XI LP, GTCR Partners XI/A&C LP, GTCR Partners XI/B LP and GTCR Investment XI LLC (collectively, “GTCR”), our Class II directors will be elected at this Annual Meeting to serve until our 2028 Annual Meeting of Shareholders, our Class I directors will serve until our 2027 Annual Meeting of Shareholders, and our Class III directors will serve until our 2026 Annual Meeting of Shareholders. In addition, our Certificate provides that our directors may be removed with or without cause by the affirmative vote of at least a majority of the voting power of our outstanding shares of stock entitled to vote generally in an election of directors, voting together as a single class, for so long as GTCR beneficially owns 40% or more, in the aggregate, of the total number of shares of our common stock then outstanding (“Voting Stock”). If GTCR no longer beneficially owns in the aggregate (directly or indirectly) 40% or more of our Voting Stock, then our directors may be removed only for cause upon the affirmative vote of at least 66 ²⁄₃% of the voting power of the outstanding shares of Voting Stock, voting together as a single class.

Director Nomination Agreement

In connection with our initial public offering (our “IPO”), we entered into a director nomination agreement (as further amended and restated, the “Director Nomination Agreement”) with MLSH 1, MLSH 2 and GTCR. The Director Nomination Agreement provides GTCR the right to nominate to the Board a number of designees equal to at least: (i) 100% of the total number of directors comprising the Board, so long as GTCR beneficially owns shares of Class A common stock and Class B common stock representing at least 40% of the total amount of shares of Class A common stock and Class B common stock GTCR owned as of the date of the IPO, (ii) 40% of the total number of directors, in the event that GTCR beneficially owns shares of Class A common stock and Class B common stock representing at least 30% but less than 40% of the total amount of shares of Class A common stock and Class B common stock GTCR owned as of the date of the IPO, (iii) 30% of the total number of directors, in the event that GTCR beneficially owns shares of Class A common stock and Class B common stock representing at least 20% but less than 30% of the total amount of shares of Class A common stock and Class B common stock GTCR owned as of the date of the IPO, (iv) 20% of the total number of directors, in the event that GTCR beneficially owns shares of Class A common stock and Class B common stock representing at least 10% but less than 20% of the total amount of shares of Class A common stock and Class B common stock GTCR owned as of the date of the IPO and (v) one director, in the event that GTCR beneficially owns shares of Class A common stock and Class B common stock representing at least 5% of the total amount of shares of Class A common stock and Class B common stock GTCR owned as of the date of the IPO. In each case, GTCR’s

8

nominees must comply with applicable law and satisfy any applicable stock exchange rules. In addition, GTCR shall be entitled to designate the replacement for any of its Board designees whose Board service terminates prior to the end of the director’s term, regardless of GTCR’s beneficial ownership at that time. GTCR shall also have the right to have its designees participate on committees of the Board proportionate to its voting power, subject to compliance with applicable law and stock exchange rules regarding the independence of such committees. The Director Nomination Agreement also prohibits us from increasing or decreasing the size of the Board without the prior written consent of GTCR. The Director Nomination Agreement will automatically terminate at such time as GTCR beneficially owns less than 5% of the shares of Class A and Class B common stock it beneficially owned as of the date of the IPO.

One of the four director nominees for election at the Annual Meeting (Mr. Cunningham) was nominated by GTCR pursuant to the Director Nomination Agreement.

Shareholder Recommendations for Director Nominees

Subject to the rights of GTCR under the Director Nomination Agreement, the Nominating, Governance and Risk Committee will evaluate candidates for director recommended by our shareholders in the same manner as director candidates identified through other means based on the criteria and process outlined in our Corporate Governance Guidelines. Shareholders who wish to identify director candidates for consideration by the Nominating and Corporate Governance Committee may write to 10770 Wateridge Circle Suite 200, San Diego, California 92121, Attn: General Counsel and Secretary, and any candidates so identified will be forwarded to the Chair of the Nominating, Governance and Risk Committee for consideration.

Shareholders may also nominate directors for election to the Board. In order to nominate a candidate for director at our 2026 Annual Meeting of Shareholders, nominations must be submitted in writing to our Corporate Secretary at our principal executive offices at 10770 Wateridge Circle Suite 200, San Diego, California 92121, and must be received no later than the close of business on February 21, 2026 and not earlier than the close of business on January 22, 2026. Nominations for director must also satisfy the other procedural requirements specified in our Bylaws. In addition to satisfying the requirements under our Bylaws, to comply with the universal proxy rules, shareholders who intend to solicit proxies in support of director nominees, other than the Company’s nominees, must provide written notice that sets forth all of the information required by Rule 14a-19 under the Exchange Act, which written notice must be postmarked or transmitted electronically to the Corporate Secretary at our principal executive offices at 10770 Wateridge Circle Suite 200, San Diego, California 92121, no later than March 23, 2026. However, if the date of our 2026 Annual Meeting of Shareholders is changed by more than 30 days from May 22, 2026, then written notice must be provided by the later of the 60th day prior to the date of our 2026 Annual Meeting of Shareholders and the 10th day following the day on which public announcement of the date of our 2026 Annual Meeting of Shareholders is first made by us.

When filling a vacancy on the Board, the Nominating, Governance and Risk Committee identifies the desired skills and experience of a new director and nominates individuals who it believes can strengthen the Board’s capabilities and further diversify the collective experience represented by the then-current directors. The Nominating, Governance and Risk Committee may engage third parties to assist in the search and provide recommendations. Also, then-current directors may be asked to recommend candidates. All candidates for director are evaluated based on the criteria and process outlined in our Corporate Governance Guidelines and the Nominating, Governance and Risk Committee charter, and the same criteria and process are used to evaluate all candidates, including candidates that may be recommended by our shareholders.

PROPOSAL 1 – ELECTION OF DIRECTORS

Based upon the recommendation of the Nominating, Governance and Risk Committee, the Board has nominated the following four directors to be re-elected to the Board at the Annual Meeting: Sean Cunningham, John DeFord, PhD, Jessica Hopfield, PhD, and Murali K. Prahalad, PhD.

If elected at the Annual Meeting, the nominees will serve for three-year terms expiring at our 2028 Annual Meeting of Shareholders and until their respective successors are duly elected and qualified, or until his or her earlier death, resignation or removal. Certain biographical information for each of the nominees is set forth below. Also set forth therein is a description of the specific experience, qualifications, attributes and skills of each nominee that were considered by the Nominating, Governance and Risk Committee, in the context of the needs of the Board as a whole, in determining that these individuals were qualified to serve on the Board.

Each nominee has consented to stand for re-election and has agreed to serve if elected. We currently have no reason to believe that any of the nominees would be unable or unwilling to serve if elected. However, if before the Annual Meeting, any nominee becomes unable to serve, or chooses not to serve, the Board may nominate a substitute. If that happens, the persons named as proxies on the proxy card will vote for the substitute. Alternatively, the Board may either let the vacancy stay unfilled until an appropriate candidate is identified or reduce the size of the Board to eliminate the vacancy.

The Board recommends that you vote “FOR” each of the director nominees.

Proxies solicited on behalf of the Board will be voted “FOR” the election of each of the four nominees, unless your proxy card is marked otherwise (if you are a registered shareholder) or you have provided a different instruction to your bank or broker (if you are a beneficial or “street name” shareholder).

Vote Required

Under our Bylaws, the election of the four director nominees at the Annual Meeting requires a plurality of the votes cast by holders of our common stock present in person or represented by proxy and entitled to vote on the election of directors. In an uncontested election of directors, this means that each director nominee will be elected if he or she receives at least one “FOR” vote. Failure to vote by proxy or to vote electronically at the Annual Meeting and “WITHHOLD” votes will result in a respective nominee having fewer votes but will have no effect on the outcome of the election because a plurality of the votes cast is required for the election of the director nominee. Cumulative voting is not permitted in the election of directors.

Director Nominees to Serve for a Three-Year Term Expiring at the 2028 Annual Meeting of Shareholders.

Sean Cunningham has served on the Board since our IPO in November 2020 and on our Nominating, Governance and Risk Committee since October 2022, and has served as a member of MLSH 1’s board since March 2016. Mr. Cunningham also serves on the Board of Directors of Sotera Health Company (“Sotera Health”), a healthcare company. Mr. Cunningham joined GTCR in 2001 where he is currently a Managing Director and Head of the Healthcare Group. Mr. Cunningham was previously a consultant with The Boston Consulting Group. Mr. Cunningham holds an MBA from the Wharton School at the University of Pennsylvania as well as a BA and BE in Engineering Sciences from Dartmouth College. We determined that Mr. Cunningham’s directorship experience with similar companies and extensive experience in the healthcare and pharmaceutical industries qualify him to serve as a director on the Board.

John DeFord, PhD has served on the Board since July 2023 and on our Audit Committee and Compensation and Leadership Development Committee since September 2023. He assumed the role of Chair of our Compensation and Leadership Development Committee in June 2024.

Summary of Director Skills, Experience & Attributes

Our directors, including those who have been nominated for re-election, comprise a group of individuals with various relevant skills, experience and attributes. Provided below is a summary of some of the key characteristics of each of our directors that are relevant to their service on the Board. The summary below is intended as a high-level summary of certain areas of knowledge, skill and experience that are germane to the Company, and is not an exhaustive list of each director’s skills or contributions to the Board.

Independence Status

The listing standards of the Nasdaq Global Select Market (“Nasdaq”) require that, subject to specified exceptions, such as those described below under the subsection entitled, “Controlled Company Status,” a majority of the members of the board of directors and each member of a listed company’s audit committee, compensation committee and nominations committee be independent and that audit committee members and compensation committee members also satisfy independence criteria set forth in Rule 10A-3 under the Exchange Act and the Nasdaq’s listing standards, respectively.

The Board has affirmatively determined that each of Messrs. Eckert and Lucier, Mses. Ashkenazi (who served on the Board until July 31, 2024) and Gray and Drs. DeFord, Hopfield and Prahalad qualified, and, as applicable, continues to qualify, as an independent director in accordance with the Nasdaq’s listing standards. In addition, the Board has determined that each of Ms. Gray and Drs. DeFord and Hopfield meets the heightened independence requirements for audit committee membership as set forth in Rule 10A-3 under the Exchange Act. In making these determinations, the Board considered the relationships (if any) that each non-employee director (and any of his or her family members) had or has with the Company and all other facts and circumstances that the Board deemed relevant, including beneficial ownership of our common stock, and found that none of such directors, nor any of his or family members, had or has a relationship with the Company, which, in the Board’s opinion, would interfere with his or her exercise of independent judgment in carrying out the responsibility of a director of the Company.

14

Controlled Company Status

GTCR controls a majority of our outstanding common stock. As a result, we are a “controlled company.” Under Nasdaq rules, a company of which more than 50% of the voting power for the election of directors is held by an individual, group or another company is a “controlled company” and may elect not to comply with certain Nasdaq corporate governance rules. From time to time, we may rely on this exemption for compliance with Nasdaq’s listing standards. Accordingly, you may not have the same protections afforded to shareholders of companies that are subject to all of Nasdaq’s corporate governance requirements. A summary of Nasdaq’s corporate governance rule exemptions for controlled companies and the extent to which we currently rely on them is set forth below.

Board Meetings and Committees

In 2024, the Board held eight meetings. The Audit Committee held seven meetings, the Compensation and Leadership Development Committee held six meetings, and the Nominating, Governance and Risk Committee held four meetings in 2024. Directors are expected to attend the annual meeting of shareholders and all or substantially all of the Board meetings and meetings of committees on which they serve. In 2024, each director attended at least 75% of the meetings of the Board and any of the committees of the Board on which the director served. All of our then-serving directors attended our 2024 Annual Meeting of Shareholders.

The Board has an Audit Committee, a Compensation and Leadership Development Committee and a Nominating, Governance and Risk Committee. The current composition, duties and responsibilities of these committees are as set forth below. In the future, the Board may establish other committees, as it deems appropriate, to assist it with its responsibilities.

Board Leadership Structure

The Board believes that an independent Chairman and the mix of experienced independent directors, as well as the GTCR-affiliated directors, that currently comprise the Board, together with the structure and composition of the Board committees, provides strong overall risk oversight and strategic direction for the Company, benefitting Maravai and all of its shareholders.

Board Mix

The Board has an effective mix of independent and management directors. The Board includes six independent directors, our Chief Executive Officer, and four representatives affiliated with our controlling shareholder, GTCR.

Chair of the Board

With respect to the roles of Chairman of the Board and Chief Executive Officer (“CEO”), our Corporate Governance Guidelines provide that the roles may be at times separated or at times combined, giving the Board discretion in combining or separating these positions as it deems appropriate in light of prevailing circumstances. Currently, the roles of CEO and Chairman are held by separate persons, and our Chairman, Mr. Eckert, is an independent director. The Chairman’s responsibilities include, but are not limited to, presiding over all meetings of the Board at which members of management are not present, including any executive sessions of independent directors, reviewing Board meeting schedules and agendas and acting as a liaison between the independent directors and the CEO. The Board may make changes to its leadership structure in the future as it deems appropriate and in the best interests of the Company and its shareholders, as part of the Company’s succession planning process or otherwise, taking into account the Board’s and Company’s needs and the composition of the Board at such time.

Management Succession

The Compensation and Leadership Development Committee makes a report to the Board on succession planning at least once a year. The entire Board works with the Compensation and Leadership Development Committee to evaluate potential successors to the CEO and other executive officers. The CEO and such other officers also make available to the Compensation and Leadership Development Committee their recommendations and evaluations of potential successors, along with a review of any development plans recommended for such individuals.

Risk Oversight

Our Nominating, Governance and Risk Committee oversees an enterprise-wide approach to risk management, designed to support the achievement of organizational objectives, to improve long-term organizational performance, and to enhance shareholder value. A fundamental part of risk management is not only understanding the most significant risks a company faces and what steps management is taking to manage those risks but also understanding what level of risk is appropriate for a given company. The involvement of our Nominating, Governance and Risk Committee in reviewing our business is an integral aspect of its assessment of the Company’s risk profile and also its determination of what constitutes an appropriate level of risk.

19

Our Nominating, Governance and Risk Committee oversees our principal operational, business, compliance, information security and ethics risks, including the appropriateness of reporting lines of authority, communications, systems and controls based on our structure, size and scope of operations, and the steps our management has taken to monitor and control these exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. In particular, our Nominating, Governance and Risk Committee is charged with overseeing our management’s efforts to identify, evaluate and mitigate major risks related to cybersecurity, data protection controls, business continuity/disaster recovery systems and other information security matters, including the prevention and timely detection of the effects of cybersecurity threats or incidents to Maravai. Our Nominating, Governance and Risk Committee also monitors compliance with legal and regulatory requirements and management provides our Nominating, Governance and Risk Committee periodic reports on our compliance programs. In addition, our Nominating, Governance and Risk Committee oversees our major corporate governance risks. Our Nominating, Governance and Risk Committee also oversees the Company’s sustainability and risk management strategy, initiatives and policies.

While our Nominating, Governance and Risk Committee has overall responsibility for risk oversight, primary oversight of certain risks has been delegated to other committees. Our Audit Committee monitors our major financial risk exposure. Our Compensation and Leadership Development Committee oversees the design and implementation of our compensation policies and programs and monitors the incentives created by these policies and programs. We are committed to ensuring the Board and its committees are consistently updated on threats to our business and receive consistent updates on risk mitigation processes.

In connection with its reviews of the operations of our business, our full Board addresses the primary risks associated with our business, such as strategic planning. The Board appreciates the evolving nature of our business and industry and is actively involved with monitoring new threats and risks as they emerge.

At periodic meetings of the Board and its committees, management reports to and seeks guidance from the Board and its committees with respect to the most significant risks that could affect our business, such as legal risks, information security and privacy risks, and financial, tax and audit related risks.

Code of Ethics

We have adopted a Code of Ethics that applies to all of our employees, officers and directors, including those officers responsible for financial reporting. Our Code of Ethics is available on our website at investors.maravai.com. We intend to disclose any amendments to our Code of Ethics, or any waivers by the Board of its requirements for any of our directors or executive officers, on our website to the extent required by SEC and/or Nasdaq rules. The information contained on or accessible through our website is not part of, nor incorporated by reference into, this proxy statement or considered to be part of this document.

Compensation Committee Interlocks and Insider Participation

None of the members of the Compensation and Leadership Development Committee who served during 2024 is or was an officer or employee of Maravai, nor did any such member have any relationship with Maravai pursuant to which disclosure would be required under applicable SEC rules pertaining to the disclosure of transactions with related persons, except as described under “Certain Relationships and Related Party Transactions—Director Nomination Agreement.”

No interlocking relationships exist between any of the members of the Board or the Compensation and Leadership Development Committee and the Board or compensation committee of any other company.

The total compensation of each NEO is reported in the Fiscal Year 2024 Summary Compensation Table presented on page 37 of this proxy statement.

Our compensation program is intended to motivate and incentivize our executive officers to achieve our corporate objectives and increase shareholder value. The Compensation and Leadership Development Committee continues to evaluate how best to structure our compensation program to ensure that our executives are being appropriately and competitively compensated while also maintaining compensation levels commensurate with our business performance. During fiscal year 2024, as part of our ongoing effort to align our compensation program with best practices, the Compensation and Leadership Development Committee utilized the services of its compensation consultant, Meridian Compensation Partners, LLC (“Meridian”), to evaluate our executive compensation programs. Our fiscal year 2024 compensation program was informed by these efforts.

In 2022, we requested that shareholders approve, on a non-binding, advisory basis, the frequency of our future “say-on-pay” votes, and, as a result of such vote, we expect to conduct the vote to approve, on a non-binding, advisory basis, the compensation of our NEOs once every year.

At our 2024 Annual Meeting of Shareholders, our second “say-on-pay” advisory vote received 97.83% support. The Compensation and Leadership Development Committee considered the shareholders’ strong support of our say-on-pay vote at our 2024 Annual Meeting of Shareholders when reviewing and designing our executive compensation program for 2025.

The Compensation and Leadership Development Committee will consider the results of future advisory votes on executive compensation as our compensation philosophy continues to evolve and future compensation decisions are made.

24

Compensation Philosophy and Objectives

The overall objective of our compensation program is to encourage and reward the creation of sustainable, long-term value. We pursue this objective via:

The key elements of our compensation program for our NEOs include:

25

Pay for performance is a principle imbedded throughout our compensation strategy, our compensation program designs and our compensation decisions. Our compensation program promotes long-term performance and long-term shareholder value creation. The majority of each NEO’s total compensation is “at risk” through annual bonuses and long-term equity incentive awards. Total compensation includes the sum of an NEO’s base salary, target annual bonus and equity awards. The following charts show the mix of fixed compensation (base salary as of December 31, 2024) and at-risk compensation (target annual bonuses and the grant date fair value of annual equity awards of our NEOs in 2024):

Compensation-Setting Process

Role of the Compensation and Leadership Development Committee and Board

The Compensation and Leadership Development Committee sets the philosophy, objectives, elements, policies and practices of compensation for our executive officers, including our NEOs, considering such factors as each NEO’s professional experience, job scope, past performance, tenure and retention risk. The Compensation and Leadership Development Committee also considers prior fiscal year adjustments to compensation, historical annual bonus award payments and equity awards. Finally, the Compensation and Leadership Development Committee considers current market practices, based on its review of executive compensation data for comparable companies, as well as current compensation trends, to ensure that the compensation of the NEOs is both competitive and reasonable, while also maintaining compensation levels commensurate with our financial and stock performance.

The independent directors of our Board make all final compensation decisions for the CEO (based on the recommendation of the Compensation and Leadership Development Committee), while the Compensation and Leadership Development Committee makes all final compensation decisions for other executive officers (considering recommendations from our CEO). These decisions include:

26

Role of Independent Compensation Consultant

The Compensation and Leadership Development Committee has the authority to retain compensation consultants and other advisors to assist it in fulfilling its duties and responsibilities and has directly retained Meridian, an independent compensation consulting firm, to provide research and analysis and to make recommendations on the form and level of executive compensation. The Compensation and Leadership Development Committee sought input from Meridian on executive compensation matters for 2024, including the design and competitive position of our executive compensation program, our 2024 Peer Group (as defined below), appropriate compensation levels, and evolving compensation trends.

Based on its consideration of the various factors set forth in the rules promulgated by the SEC and the Nasdaq listing rules, the Compensation and Leadership Development Committee has determined that the work performed by Meridian has not raised any conflict of interest.

Role of CEO

The Compensation and Leadership Development Committee considers recommendations from our CEO when making decisions regarding our executive compensation program and the compensation of our executive officers other than our CEO. During the annual compensation planning process, our CEO recommends targets for all incentive compensation programs, other than himself. The targets are based on our Board-approved annual operating plan and strategic objectives. As part of the annual performance review process, which includes an assessment of each executive officer’s (except his own) performance against individual objectives, the CEO presents an evaluation of each executive officer’s contributions and recommends specific compensation for such other executive officers, including base salary level adjustments and annual cash incentive and equity awards.

Competitive Positioning

Meridian presented a competitive market analysis to support the Compensation and Leadership Development Committee in connection with its executive and non-employee director compensation decisions made in the first half of 2024. To develop an understanding of the competitive marketplace, the Compensation and Leadership Development Committee reviewed the executive compensation practices of a group of publicly-traded companies and broader life sciences data from Radford’s proprietary survey database. Meridian worked with the Compensation and Leadership Development Committee to establish the Company’s 2024 Peer Group.

The Compensation and Leadership Development Committee uses the market analysis as a reference point to ensure that our executive compensation program is competitive with market practice. In the case of each executive officer, the Compensation and Leadership Development Committee considers the overall compensation of each individual against the compensation data developed through the market analysis, and whether his or her position is sufficiently similar to the positions identified in the data to make the comparison meaningful. Ultimately, the Compensation and Leadership Development Committee’s decisions with respect to each executive’s total compensation, and each individual compensation element, are based in large part on its assessment of Company and individual performance as well as other factors, such as internal pay equity.

At the time of the peer group review for 2024, demand for COVID-19 related products and services had subsided, impacting our financial performance, including our revenue. Relative to the 17 peers in the 2023 Peer

27

Group, we were positioned 15^th out of 18 in terms of trailing twelve months revenue and 16^th out of 18 in terms of market capitalization. The Compensation and Leadership Development Committee and Meridian reviewed and considered factors such as labor market competitors, industry, total revenue, market capitalization, growth and profitability margins in determining how to modify the 2023 peer group in order to create a 2024 Peer Group to be used in making compensation decisions for 2024.

Relative to the 2023 peer group, the Compensation and Leadership Development Committee approved the removal of Bruker Corporation, Medpace Holdings, Inc. and Waters Corporation, each of whom, at the time of selection of the revised peer group, were much larger than us with respect to revenue and market capitalization while also being less relevant labor market competitors as compared to other large peers such as Bio-Rad Laboratories, Inc. The Compensation and Leadership Development Committee also approved the addition of Cytek Biosciences, Inc., Fulgent Genetics, Inc., NeoGenomics, Inc., Twist Bioscience Corp, and Veracyte, Inc, each of whom had lower revenue than our own at time of selection, and, to further expand the overall size of the peer group, Lantheus Holdings, Inc. Following these updates, the peer group for 2024 (the “2024 Peer Group”) represented a robust sample of 20 sector-relevant companies, as follows:

At time of selection, we were positioned 13^th out of 21 companies with respect to trailing twelve months revenue and 14^th out of 21 companies with respect to market capitalization.

Compensation Elements

Base Salaries

During 2024, the Compensation and Leadership Development Committee reviewed the base salaries of the NEOs and (i) made adjustments (with respect to each NEO except the CEO) and (ii) recommended adjustments to the Board (with respect to the CEO), with consideration given to unique qualifications, substantial contributions and internal value to the Company as well as alignment with competitive market data.

28

Annual Bonus

The Compensation and Leadership Development Committee periodically reviews and determines (for each NEO other than the CEO) and recommends to the Board (for the CEO) the target annual bonus award opportunities (expressed as a percentage of base salary) that each of the NEOs is eligible to earn. The target annual bonus award opportunity for each NEO was initially established in his or her employment agreement and is reviewed periodically by the Compensation and Leadership Development Committee.

The actual annual bonus amount earned each year by our NEOs may be more or less than the target amount depending on an assessment of the performance of the Company (the company performance factor or “CPF”) and, for our NEOs other than the CEO, the individual’s performance against a set of pre-established goals and objectives (the individual performance factor or “IPF”), in each case, conducted after the end of the fiscal year.

For the 2024 annual bonus (the “2024 Annual Bonus”), CPF referenced both revenue and Adjusted Earnings Before Interest Taxes Depreciation and Amortization (“Adjusted EBITDA”) goals, which were weighted 70% and 30%, respectively. Revenue is revenue as determined in accordance with GAAP, as reflected in our consolidated financial statements. Adjusted EBITDA is a non-GAAP financial measure and is defined at the end of this Compensation Discussion and Analysis.

The table below illustrates the CPF application to various levels of performance against our 2024 Annual Bonus goals. Revenue and Adjusted EBITDA achievement relative to 2024 Annual Bonus goals determine performance scores for each metric. For the 2024 Annual Bonus Goals, the revenue target was $291.7 million, and the Adjusted EBITDA target was $65.3 million. A weighted average of the applicable performance scores for each metric is calculated to produce the CPF (expressed as a percentage of target bonus award opportunity, rounded to the next whole percentage point), subject to a maximum CPF equal to 200% of target, which is then multiplied by the NEO’s bonus target. Linear interpolation is applied to the performance scores for performance between threshold and target and between target and maximum.

Achievement of 100% of target goals (referencing our 2024 budget) for both revenue and Adjusted EBITDA would fund a payout at 100% of target bonus award opportunities for the CPF portion of the bonus. For both the revenue and Adjusted EBITDA components, threshold achievement of 80% of the target goal was necessary to fund the minimum payout of 50% of target bonus allocated to the measure, and achievement of 120% or greater of the target goal would result in a maximum payout of 200% of target bonus allocated to the measure.

29

Individual performance objectives for the IPF are described below.

In 2024, for our NEOs other than the CEO (who did not have an IPF component), the CPF received 80% weighting while the IPF received 20% weighting.

Each NEO’s annual bonus payout was determined using the following formulae:

Achievement of Company Performance Factor

For 2024, our performance for revenue ($259.2M) achieved 88.8% of the target achievement level, and our performance for Adjusted EBITDA ($43.6M) was below the threshold achievement level. After application of our CPF formula calculation as described above, the Compensation and Leadership Development Committee approved a 50.5% payout for the CPF.

30

Achievement of Individual Performance Factor

Our CEO evaluated the actual performance of our NEOs who were eligible for the IPF component against the achievement of individual performance objectives and submitted such evaluations to the Compensation and Leadership Development Committee. The ultimate determination of achievement of the individual performance objectives and the IPF score is at the sole discretion of the Compensation and Leadership Development Committee. The performance assessment for the individual performance objectives is not calculated on a line-item basis, but rather represents an overall assessment of how the NEO contributed to the success of the Company through and within his or her area of responsibility. The individual performance objectives are designed to be challenging to achieve at 100% of target performance level. The Compensation and Leadership Development Committee has assessed the attainment of these objectives for Messrs. Herde and Burch, Dr. Leddy and Ms. Buzzeo and determined an IPF score for such NEOs as described below.

After application of our CPF and IPF formulae as described above, the Compensation and Leadership Development Committee approved actual bonus payments as set forth below:

31

Equity Awards

2024 Incentive Equity Awards

On January 16, 2024, we granted annual equity awards to our NEOs, comprised of RSUs under the Maravai LifeSciences Holdings, Inc. 2020 Omnibus Incentive Plan (the “Omnibus Plan”). We used RSUs due to the retentive effect of time-based RSUs. The Compensation and Leadership Development Committee selected RSUs as the equity vehicle after considering market practices, the overall level of pay for our executives and the long-term orientation of the equity award vehicle.

The Compensation and Leadership Development Committee approved the following equity incentives to our NEOs in 2024:

Except for Mr. Martin, whose 2023 equity award was limited to performance-based restricted stock units intended to provide a more meaningful incentive in light of the difference between our then-current stock price and the $60 and $100 performance targets associated with inducement performance stock units he received upon hire, and Ms. Buzzeo, whose role expanded materially since her 2023 award, these grant date fair values represent a reduction ranging from 26% to 28% as compared to grant date fair values of 2023 awards.

After considering the reduction in targeted values as compared to the prior year, the importance of fostering management continuity during 2024 following the leadership transitions at the Company in 2023, and the modest value attributable to unvested equity awards issued in prior years, including underwater options, the Compensation and Leadership Development Committee determined to shorten the vesting schedule from its prior practice of vesting in three equal tranches over three years to two equal tranches over two years.

Employment Agreements and Severance Benefits

We are party to employment agreements with our NEOs, which provide eligibility for severance payments and benefits in connection with certain qualifying terminations of employment, including enhanced severance payments and benefits in connection with such qualifying termination that occurs in connection with a change in control. Upon his termination of employment in January 2025, Mr. Burch received severance in accordance with the terms of his employment agreement. The terms of the employment agreements with our NEOs are described in the sections captioned “Narrative to Summary Compensation Table and 2024 Grants of Plan-Based Awards Table” and “Potential Payments upon a Termination of Employment or a Change in Control.”

The NEOs’ outstanding equity awards are generally subject to accelerated vesting upon certain qualifying terminations of employment that occur within two years of a change in control. For additional detail, see the section titled “—Equity Awards—2023 Amendments to Certain Outstanding Incentive Equity Awards” above and the section titled “Potential Payments upon a Termination of Employment or a Change in Control” below.

Retirement Plan, ESPP, Health and Welfare Benefits, and Perquisites

We do not have a defined benefit pension plan or nonqualified deferred compensation plan. We currently maintain a retirement plan intended to provide benefits under Section 401(k) of the Internal Revenue Code of

32

1986, as amended (the “Code”), pursuant to which employees, including the NEOs, can make voluntary pre-tax contributions or Roth post-tax contributions. We match 50% of elective deferrals up to the first 6% of such participant’s annual base salary for all participants. Prior to January 1, 2024 matching contributions vested on the second anniversary of the participant’s date of hire; however, starting January 1, 2024, all matching contributions are fully vested for all employees. All contributions under the plan are subject to certain annual dollar limitations, which are periodically adjusted for changes in the cost of living.

We also maintain the 2020 Employee Stock Purchase Plan (“ESPP”). The ESPP authorizes the grant of options to employees, including the NEOs, so long as they do not own stock representing 5% or more of the total combined voting power or value of all classes of Common Stock and other stock of the Company, a Parent or a Subsidiary. Due to our “Up-C” structure, the ESPP is not currently tax-qualified under Section 423 of the Code. Each offering period is approximately twenty-four months in duration commencing on each May 16th and November 16th of each year during the term of the ESPP. The ESPP allows participants to purchase Class A common stock through payroll deductions of up to 15% of their eligible compensation. The purchase price of the shares is 85% of the lower of the fair market value of our Class A common stock on the grant date or purchase date. All salaried employes are generally eligible to participate in the ESPP.

All full-time employees, including the NEOs, are eligible to participate in health and welfare benefit programs, including medical, dental and vision care coverage, disability, and life insurance.

The benefits described above are provided to our executive officers, including our NEOs, on the same basis as other eligible employees.

The Board believes that it is in the best interest of the Company to facilitate private aircraft travel for our Chief Executive Officer in order to best enable conduct of business in a manner that promotes safety and efficiency. The Board also believes that it is in the best interest of the Company to facilitate private aircraft travel for our other executive officers for business travel and, in limited circumstances, personal travel. Accordingly, the Board adopted an aircraft use policy pursuant to which the Company arranged for flights for Mr. Martin and Mr. Herde, certain of which were not integrally and directly related to the performance of their duties, and which conferred a personal benefit to them. The incremental cost to the Company of such flights is included in the “All Other Compensation” column of the Summary Compensation Table below. Neither Mr. Martin nor Mr. Herde received a gross-up for any of the imputed income associated with such flights.

33

Anti-Hedging and Anti-Pledging Policy

Pursuant to our Insider Trading Policy, we prohibit our employees, directors and officers from engaging in hedging transactions, including hedging or monetization transaction mechanisms and the use of financial instruments such as prepaid variable forwards, equity swaps, collars and exchange funds. Additionally, directors, officers and other employees are prohibited from holding our securities in a margin account or otherwise pledging our securities as collateral for a loan.

Stock Ownership Guidelines

In July 2023, we adopted revised minimum stock ownership guidelines applicable to non-employee independent directors and executive officers. Guidelines are shown in the table below:

While the guidelines do not prescribe a timeline for compliance, they require executives subject to the guidelines to hold at least 50% of the stock received from equity awards (on a shares-issued, net-of-tax-withholding basis) until the minimum ownership requirement level is achieved, or at any time their ownership subsequently falls below the guidelines.

The following shares and awards may be counted for purposes of assessing compliance with the guidelines:

Unexercised stock options and unvested performance-based stock (and stock unit awards) are excluded for purposes of these guidelines.

Compensation Risk Assessment

The Compensation and Leadership Development Committee has reviewed our incentive compensation programs, discussed the concept of risk as it relates to our compensation program, considered various mitigating factors and reviewed these items with Meridian. In addition, the Compensation and Leadership Development Committee reviewed an independent risk assessment of our executive compensation program conducted by Meridian. Based on these reviews and discussions, the Compensation and Leadership Development Committee does not believe our compensation program creates risks that are reasonably likely to have a material adverse effect on our business.

35

Tax and Accounting Considerations

We operate our compensation programs with the good faith intention of complying with Section 409A of the Code. We account for equity-based payments with respect to our long-term equity incentive award programs in accordance with the requirements of FASB ASC Topic 718, Compensation—Stock Compensation.

In evaluating the Company’s executive compensation program, the Compensation and Leadership Development Committee considers tax and accounting treatment, balancing the effects on the individual and the Company. The Compensation and Leadership Development Committee believes that the potential deductibility of the compensation payable under those programs should be only one of a number of relevant factors taken into consideration, and not the sole or primary factor, in establishing the cash and equity compensation programs for the executive officers. Section 162(m) of the Code generally limits to $1.0 million the amount of remuneration that the Company may deduct in any calendar year for certain executive officers. The Compensation and Leadership Development Committee believes that cash and equity incentive compensation must be maintained at the requisite level to attract and retain the executive officers essential to the Company’s financial success, even if all or part of that compensation may not be deductible by reason of the Section 162(m) limitation. Accordingly, the Compensation and Leadership Development Committee will continue to maintain flexibility and the ability to pay competitive compensation by not requiring all compensation to be deductible.

Non-GAAP Financial Measures and Other Definitions

Certain of the performance measurements referred to in the CD&A are “non-GAAP financial measures” under SEC rules and regulations. The disclosure below reflects how those non-GAAP financial measures were calculated.

We define Adjusted EBITDA as net (loss) income before interest, taxes, depreciation and amortization, certain non-cash items and other adjustments that we do not consider in our evaluation of ongoing operating performance from period to period. For information about how we calculate Adjusted EBITDA, please see Note 7 to the consolidated financial statements included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024.

Compensation and Leadership Development Committee Report

The Compensation and Leadership Development Committee has reviewed and discussed with management the Compensation Discussion and Analysis as set forth in this proxy statement. Based upon this review and discussion, the Compensation and Leadership Development Committee recommended to the Board that the Compensation Discussion and Analysis be incorporated by reference in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, and included in the Company’s proxy statement filed in connection with the Company’s 2025 Annual Meeting of Shareholders.

Additional Narrative Disclosure

Retirement Benefits

We do not have a defined benefit pension plan or nonqualified deferred compensation plan. We currently maintain a retirement plan intended to provide benefits under Section 401(k) of the Code, pursuant to which employees, including the NEOs, can make voluntary pre-tax contributions. See “Compensation Discussion and Analysis—No Special Retirement, Health or Welfare Benefits” above for additional information regarding 401(k) plan contributions.

Employee Stock Purchase Plan

The ESPP authorizes the grant of options to employees, which due to our “Up-C” structure is not currently tax-qualified under Section 423 of the Code. See “Compensation Discussion and Analysis—No Special Retirement, Health or Welfare Benefits” above for additional information regarding the ESPP.

Incentive Units

Prior to our 2020 IPO, we offered equity incentives to certain of our NEOs through grants of incentive units in MLSH 1 (the “MLSH 1 Units”). Certain of these incentive unit awards were subject to time-based vesting requirements and accelerated vesting upon the occurrence of certain terminations of employment and certain change-in-control events, and the remaining incentive unit awards were subject to market and performance-based vesting requirements and would terminate if such performance-based vesting requirements were not met upon certain change-in-control events. The consummation of our IPO did not trigger accelerated vesting of any of the MLSH 1 Units that were subject to time-based vesting requirements; however, the vesting of the incentive units subject to performance-based vesting requirements was achieved as a result of the IPO. Subsequent to the IPO, all time-based vesting requirements have been satisfied and the MLSH 1 Units (if any) held by our NEOs as of December 31, 2024, were fully vested.

Potential Payments Upon Termination or Change in Control

Each of the NEOs are party to employment agreements that provide for severance benefits (as described below), in the event the NEO’s employment is terminated (i) by the Board without “cause” (a “Termination without Cause”) or, with respect to certain NEOs, by such NEOs for “good reason” (a “Termination for Good Reason”), prior to a Change in Control (as defined in the Omnibus Plan) or (ii) more than two years after a Change in Control. Additionally, the NEOs are entitled to enhanced severance benefits upon a termination without “cause” or a resignation for “good reason” that occurs upon or within two years immediately following a Change in Control (a “Change in Control Termination”). Such severance benefits, in each case, are subject to each NEO’s execution and non-revocation of a general release of claims. Upon a termination for any reason, the NEO will receive any payments or benefits that have been accrued through the date of termination or are required to be paid pursuant to applicable law.

Pursuant to the Amended and Restated Employment Agreement entered into as of May 8, 2023, between Mr. Martin, Maravai LifeSciences Holdings, Inc. and Maravai Intermediate Holdings, LLC, Mr. Martin is entitled to certain severance benefits upon a Termination without Cause, a Termination for Good Reason or a Change in Control Termination. Mr. Martin’s severance benefits in the event of a Termination without Cause or a Termination for Good Reason that is not a Change in Control Termination consist of: any earned and unpaid annual bonus for the calendar year ending prior to the date of termination (“Earned Bonus Severance”); a pro-rated target annual bonus for the fiscal year during which Mr. Martin’s termination occurs (“Pro Rata Bonus Severance”); continued payment of base salary (“Base Salary Severance”) for a period of 12 months, payable during the 12-month period commencing on the date of termination in substantially equal installments in accordance with regular payroll practices as in effect on the date of the termination. Additionally, Mr. Martin will receive a payment equivalent to the amount the COBRA premium would be for Mr. Martins’ health coverage

42

prior to the termination (for Mr. Matin and Mr. Martin’s family to the extent applicable) (the “COBRA Severance”) for up to 12 months. In the event of a Change in Control Termination, Mr. Martin will receive: the Earned Bonus Severance; the Pro Rata Bonus Severance; an amount equal to two times the greatest of: (I) Mr. Martin’s target annual bonus for the fiscal year in which the Change in Control Termination occurs; (II) the calculation of an annual bonus based on (a) Mr. Martin’s annual base salary and annual bonus target in place at the time of the Change in Control and (b) the average of the Company Performance Factor achievement percentage applied to calculate annual bonuses under the Company’s annual bonus program with respect to the two fiscal years prior to the fiscal year in which the Change in Control Termination occurs; and (III) the annualized amount accrued by the Company in its financial statements as of the date of the Change in Control Termination with respect to Mr. Martin’s annual bonus for the fiscal year in which the Change in Control Termination occurs, in each case payable during the twenty-four month period commencing on the date of termination in substantially equal installments in accordance with regular payroll practices as in effect on the date of the termination (“CIC Termination Bonus Severance”); 24 months of Base Salary Severance, payable during the 24-month period commencing on the date of termination in substantially equal installments in accordance with regular payroll practices as in effect on the date of the termination; and COBRA Severance for up to 18 months.

Pursuant to the Amended and Restated Employment Agreement entered into as of May 8, 2023, between Ms. Buzzeo, Maravai LifeSciences Holdings, Inc. and Maravai Intermediate Holdings, LLC, Ms. Buzzeo is entitled to certain severance benefits upon a Termination without Cause or a Change in Control Termination.

43

Ms. Buzzeo’s severance benefits consist of: Earned Bonus Severance; Pro Rata Bonus Severance; 12 months continued Base Salary Severance, payable during the 12-month period commencing on the date of termination in substantially equal installments in accordance with regular payroll practices as in effect on the date of the termination; and COBRA Severance for up to 12 months.

No NEO shall be entitled to receive the severance benefits described above unless such NEO has timely executed and delivered within 30 calendar days of such NEO’s separation, or, in the event that the NEO’s termination of employment is “in connection with an exit incentive or other employment termination program” (as such phrase is defined in the Age Discrimination in Employment Act of 1967), the date that is 60 days following the date of such NEO’s separation, a general release and separation agreement (a “Release Agreement”) (and such Release Agreement shall become in full force and effect and not have been timely revoked as may be permitted by its terms), and such NEO shall be entitled to receive such severance benefits only so long as such NEO has not breached any of the provisions of such Release Agreement or the Non-Competition and Non-Solicitation Covenants (as defined below).

The employment agreements also subject the NEOs to certain restrictive covenants, including perpetual confidentiality, assignment of inventions, non-competition and non-solicitation covenants (the “Non-Competition and Non-Solicitation Covenants”). The Non-Competition and Non-Solicitation Covenants apply during each of the NEO’s employment and, with respect to the non-solicitation covenants only, for one-year following the NEO’s termination of employment.

Pursuant to the applicable award agreements (and amendments thereto made in May 2023), unvested stock options and restricted stock units will become 100% vested and exercisable (if applicable) if such NEO’s employment is terminated by us without “cause” or by the NEO for “good reason” within two years following a “change in control,” each as defined in the NEO’s employment agreement. Additionally, with respect to Mr. Martin’s PSUs, in the event a change in control (as defined in the Omnibus Plan) occurs prior to third anniversary of the grant date, the PSUs automatically convert into time-based restricted stock units that would vest immediately upon a termination of Mr. Martin’s employment by the Company without “cause” or by Mr. Martin for “good reason” (each, as defined in Mr. Martin’s employment agreement) occurring within two years of such change in control.

The NEOs are eligible to receive consideration with respect to their outstanding MLSH 1 Units upon a “sale” of MLSH 1, which is generally the sale of (i) MLSH 1’s equity securities pursuant to which an independent third party or parties acquires a majority of the equity securities or voting power to elect a majority of the board of directors of MLSH 1 or (ii) all or substantially all of MLSH 1’s assets on a consolidated basis (a “MLSH 1 Sale”).

The following table sets forth quantitative estimates of the benefits that would have accrued to each of our NEOs if such NEO’s employment had been terminated without cause on December 31, 2024. Amounts below reflect potential payments pursuant to the employment agreements for such NEOs.

Non-Employee Director Compensation Policy

Our non-employee directors are eligible to receive the annual cash retainers listed below for their service on the Board and committees of the Board. Non-employee directors who are employees of GTCR or its affiliates have agreed or are otherwise obligated to transfer all or a portion of the cash compensation they receive for their service as directors to GTCR or its affiliates. The retainers are paid in arrears in four equal quarterly installments and prorated for any partial year of service on the Board, and at the election of the non-employee director may be payable in fully vested shares of our Class A common stock.

Pursuant to our Non-Employee Director Compensation Policy, in 2024, our non-employee directors received a grant of RSUs (each, an “Annual Grant”) pursuant to the Omnibus Plan with a fair market value on the date of grant equal to approximately $200,000 (based on the twenty trading-day volume-weighted average price of the Company’s Class A Common Stock as of the grant date (the “20-Day VWAP”)). The Annual Grants vest in full upon the earlier to occur of (i) the first anniversary of the date of grant and (ii) the date of the next Annual Meeting of Shareholders of the Company following the date of grant, subject to the respective non-employee director’s continued service on the Board through such date. In the event a new non-employee director is elected or appointed to the Board, such non-employee director will receive an RSU grant pursuant to the Omnibus Plan with a fair market value on the date of grant equal to approximately $400,000 for the director’s first year of service on the Board. The RSUs granted upon a director’s election or appointment vest in three equal installments on the first three anniversaries of the date of grant, subject to such non-employee director’s continued service on the Board through each such anniversary date.

In connection with his service as Chairman of the Board, Mr. Eckert (i) received a grant of RSUs pursuant to the Omnibus Plan with a grant date fair value of $750,000 (based on the closing price of the Company’s Class A common stock on the date of grant), of which one-third of the RSUs were fully vested upon the date of grant, and the remaining RSUs will vest in two equal installments on May 22, 2025 and May 22, 2026, and (ii) became eligible to receive an annual cash retainer of $175,000 commencing January 1, 2025, which retainer is payable in arrears in four equal installments. Furthermore, subject to his service as Chairman of the Board on the respective grant dates, Mr. Eckert (i) will receive a grant of a RSUs pursuant to the Omnibus Plan on or around the Annual Meeting with a grant date fair value of $500,000 (based on the closing price of the Company’s Class A common stock on the date of grant), of which one-half of the RSUs shall be fully vested upon the date of grant and the remaining RSUs shall vest on the one-year anniversary of the date of grant, and (ii) beginning in 2026 and beyond, will receive a grant of RSUs pursuant to the Omnibus Plan with a fair market value on the date of grant equal to approximately $200,000 (based on the 20-Day VWAP), pursuant to the Non-Employee Director Compensation Policy, with the same vesting terms as the Annual Grants, in each case subject to Mr. Eckert’s continued service on the Board through such date.

All non-employee directors are also reimbursed for their reasonable expenses to attend meetings of the Board and related committees and otherwise attend to our business.

The following table presents the total compensation for each person who served as a non-employee member of the Board during 2024. Other than as set forth in the table and described more fully below, we did not pay any cash or other compensation, or grant any equity or non-equity awards to, any of the other non-employee members of the Board in 2024. Each of (i) Mr. Hull, our former Executive Chairman of the Board, received, and (ii) Mr. Martin, our Chief Executive Officer, receives no additional compensation for service as a director and, consequently, are not included in this table. The compensation received by Mr. Martin as an employee of the Company is presented in “—Summary Compensation Table.”

CHIEF EXECUTIVE OFFICER PAY RATIO

Under Section 953(b) of the Dodd-Frank Wall Street Reform and Consumer Protection Act and Item 402(u) of Regulation S-K, we are required to provide the ratio of the annual total compensation of Mr. Martin, to the annual total compensation of the median employee of the Company.

For the fiscal year ended December 31, 2024:

This pay ratio is a reasonable estimate calculated in a manner consistent with SEC rules based on the methodology described below. The SEC rules for identifying the median compensated employee and calculating the pay ratio allow companies to adopt a variety of methodologies, apply certain exclusions, and make reasonable estimates and assumptions that reflect their compensation practices. As such, the pay ratio reported by other companies may not be comparable to the pay ratio reported above, as other companies may utilize different methodologies, exclusions, estimates, and assumptions in calculating their own pay ratios.

Methodology

In determining the annual total compensation of our Chief Executive Officer, we annualized the annual total compensation paid to Mr. Martin, who served as the CEO on December 31, 2024, the date that we used to identify our median employee.

Pursuant to Item 402(u)(4)(ii) of Regulation S-K, we excluded all of our “non-U.S. employees” (as defined therein) for purposes of determining the median compensated employee, specifically, four employees who reside in the United Kingdom. As of December 31, 2024, we had 574 full-time U.S. employees and four full-time non-U.S. employees.

We used December 31, 2024, the end of our most recent fiscal year, as the date to determine the median employee (the “Determination Date”). The median compensated employee was determined by utilizing a consistently applied compensation measure based on the gross pay reflected on the 2024 IRS Form W-2 for each employee of the Company (“Gross Pay”). For each employee that was hired in 2024, and therefore their Gross Pay as of December 31, 2024 did not reflect a full year’s pay, we annualized their wages and/or salary, deducting from their Gross Pay and not including in such annualized amount any income attributable to: (i) cash bonuses paid to such employee throughout the year, (ii) the purchase of shares of our Class A common stock pursuant to our ESPP, (iii) the vesting of RSUs, (iv) the exercise of stock options, and (v) vehicle allowances, all of which are already included in Gross Pay and not indicative of annual salary or wages.

Using this approach, we identified our median employee and then calculated the annual total compensation of this employee for 2024 in accordance with the requirements of the Summary Compensation Table.
