PROXY STATEMENT
ANNUAL MEETING OF SHAREHOLDERS
TO BE HELD MAY 22, 2024

The accompanying proxy is solicited by the Board of Directors (the Board) of Markel Group Inc. (Markel Group, or the Company) for use at the 2024 Annual Meeting of Shareholders of the Company (the 2024 Annual Meeting) to be held May 22, 2024, or any adjournments of the meeting, for the purposes set forth in this Proxy Statement and the attached Notice of Annual Meeting of Shareholders. A Notice of Internet Availability of Proxy Materials (the E-Proxy Notice), containing instructions on how to access this Proxy Statement and the Company’s Annual Report to Shareholders for the fiscal year ended December 31, 2023 (the Annual Report to Shareholders) online, was mailed or emailed to most of the Company’s shareholders on or about April 4, 2024. On or about that date, we also began mailing a full set of proxy materials to other shareholders, including those shareholders who had previously requested paper copies of our proxy materials.

If you received the E-Proxy Notice by mail, you will not automatically receive a paper copy of the proxy materials. Instead, the E-Proxy Notice instructs you how you may access and review all of the important information contained in the proxy materials, including the Annual Report to Shareholders. The E-Proxy Notice also instructs you how you may submit your proxy. If you would like to receive a paper or email copy of our proxy materials, including the Annual Report to Shareholders, you should follow the instructions for requesting those materials included in the E-Proxy Notice.

Record Date

The Board has fixed the close of business on March 14, 2024 as the record date for the determination of shareholders entitled to notice of, and to vote at, the 2024 Annual Meeting and any adjournments thereof. Each holder of record of the Company’s common stock, no par value (the Common Stock), on the record date will be entitled to one vote for each share registered in the holder’s name with respect to each matter properly brought before the 2024 Annual Meeting. As of the close of business on the record date, 13,037,342 shares of Common Stock were outstanding and entitled to vote at the 2024 Annual Meeting. A majority of the outstanding shares of Common Stock on the record date constitutes a quorum for the 2024 Annual Meeting. Abstentions and shares held of record by a broker or its nominee that are voted on any matter at the 2024 Annual Meeting are counted in determining a quorum.

Solicitation

If sufficient proxies are not returned in response to this solicitation, supplementary solicitations may also be made by mail, telephone, electronic communication or personal interview by directors, officers and employees of the Company, none of whom will receive additional compensation for these services. The Company may retain an outside proxy solicitation firm to assist in the solicitation of proxies, but at this time does not plan to do so. Costs of solicitation of proxies will be borne by the Company, which will reimburse banks, brokerage firms and other custodians, nominees and fiduciaries for reasonable out-of-pocket expenses incurred by them in forwarding proxy materials to the beneficial owners of shares held by them.

Proxies

The shares represented by all properly executed proxies timely received by the Secretary of the Company will be voted as set forth in the proxy. Where no direction is given for a proposal on a timely received proxy, such proxy will be voted in the manner recommended by the Company for that proposal. Any proxy may be revoked at any time before the shares to which it relates are voted, either by written notice (which may be in the form of a substitute proxy bearing a later date delivered to the Secretary of the Company) or by attending the 2024 Annual Meeting and voting in person.

Householding

The Company has adopted the “householding” procedure approved by the Securities and Exchange Commission (SEC), which allows us to send one copy of the Proxy Statement, the Annual Report to Shareholders and/or the E-Proxy Notice to multiple shareholders sharing an address, unless we have received contrary instructions from one or more of the shareholders. This procedure is more environmentally friendly and cost-effective because it reduces the number of copies to be printed and mailed.

If you would like to change your householding election, request that a single copy of the proxy materials be sent to your address, or request a separate copy of the proxy materials, please contact our distribution agent, Broadridge Financial Solutions, by calling 1-866-540-7095 or by writing to Broadridge Householding Department, 51 Mercedes Way, Edgewood, NY 11717. We will promptly deliver the proxy materials to you upon receipt of your request. If you hold your shares in street name, please contact your bank, broker, or other record holder to request information about householding.

Votes Required

The following table summarizes the votes required to approve each proposal that will be voted on at the 2024 Annual Meeting, how votes will be counted for each proposal and the Board’s voting recommendation for each proposal:

Proposals		Voting Options	Votes Requireda	Effect of Abstentions and Broker Non-Votesb	Broker Discretionary Voting Allowed	Board Recommendation
1. Election of directors		“FOR” “AGAINST” “ABSTAIN”	Majority of votes cast for each nominee	No effect	No	“FOR”
2. Advisory vote on approval of executive compensation		“FOR” “AGAINST” “ABSTAIN”	Majority of votes cast	No effect	No	“FOR”
3. Approval of Company’s 2024 Equity Incentive Compensation Plan		“FOR” “AGAINST” “ABSTAIN”	Majority of votes cast	No effect	No	“FOR”
4. Ratification of selection of Company’s independent registered public accounting firm		“FOR” “AGAINST” “ABSTAIN”	Majority of votes cast	No effect	Yes	“FOR”
5. Shareholder proposal		“FOR” “AGAINST” “ABSTAIN”	Majority of votes cast	No effect	No	“AGAINST”
a	A majority of votes cast means that the number of shares voted “FOR” a director nominee’s election or a proposal must exceed the number of shares voted “AGAINST” the director nominee’s election or the proposal. In an uncontested election, if an incumbent nominee does not receive a majority of votes cast for the election of such nominee, such nominee will continue to serve on the Board as a “holdover director” and will be required to submit a letter of resignation promptly to the Board for consideration. In a contested election, where the number of nominees for director exceeds the number of directors to be elected, directors are elected by a plurality of the votes cast. If there are more persons properly nominated for election than the number of available Board positions, then the nominees receiving the most votes will be elected for the available positions.
b	Abstentions and broker non-votes will not be counted as votes cast “FOR” or “AGAINST” any of the proposals presented.

ELECTION OF DIRECTORS

Nominees

Eleven incumbent directors are nominated for election to the Board for a one-year term expiring at the 2025 Annual Meeting of Shareholders or until their respective successors are elected and qualified. The Board currently consists of twelve directors.

K. Bruce Connell is not standing for re-election at the 2024 Annual Meeting of Shareholders. Consequently, Mr. Connell will cease to be a director of the Company effective as of the adjournment of the 2024 Annual Meeting. The Board will not be nominating a director to stand for election as successor to Mr. Connell at the 2024 Annual Meeting. Rather, the Board has adopted and approved a reduction in the size of the Board by one and fixed the number of directors of the Company at eleven, effective as of the commencement of the 2024 Annual Meeting. As a result, no more than eleven directors can be elected at the 2024 Annual Meeting.

All of the Company’s current directors were elected by the shareholders at the 2023 Annual Meeting of Shareholders (the 2023 Annual Meeting). All of the Company’s current directors, other than A. Lynne Puckett, attended the 2023 Annual Meeting.

Each of the nominees has consented to being named as a nominee in this Proxy Statement, has agreed to serve if elected, and has furnished to the Company the information set forth in the following table. All nominees are expected to attend the 2024 Annual Meeting, absent unusual circumstances.

The Board recommends a vote FOR the election of the nominees named below. It is expected that each of the nominees will be able to serve, but if any nominee is unable to serve for any reason (which is not now anticipated), the Board will name a substitute nominee, and the proxies will vote for that person.

The Board believes that each nominee possesses integrity; leadership and policy making experience; the communication and interpersonal skills necessary to function effectively as a member of a decision-making body; and the ability to act in the best interests of the shareholders in order to serve the Company. In addition, the nominees collectively bring to the Board a combination of business and financial expertise, community service, and diversity of experience and of background to equip the Board to deal with the range of issues it must address.

The following matrix provides self-identified information regarding the Company’s Board members and nominees, including certain types of knowledge, skills, experiences and attributes possessed by one or more of our directors and nominees that our Board believes are relevant to our businesses.

The matrix does not encompass all the knowledge, skills, experiences or attributes of our directors and nominees, and the fact that a particular knowledge, skill, experience or attribute is not listed does not mean that a director or nominee does not possess it. In addition, the absence of a particular knowledge, skill, experience or attribute with respect to any of our directors and nominees does not mean the director or nominee in question is unable to contribute to the decision-making process in that area. The type and degree of knowledge, skills, experiences and attributes listed below may vary among the Board members and nominees.

ADVISORY VOTE ON APPROVAL OF EXECUTIVE COMPENSATION

In accordance with Section 14A of the Securities Exchange Act of 1934, as amended (the Exchange Act), we are asking shareholders to approve the following non-binding advisory resolution at the 2024 Annual Meeting:

RESOLVED, that the compensation paid to the Company’s named executive officers as described in this Proxy Statement, including the Compensation Discussion and Analysis, compensation tables and narrative discussion, is hereby APPROVED on an advisory basis.

While this vote is non-binding, the Board and the Compensation Committee, which is comprised of independent directors, will take the outcome into account in considering future executive compensation arrangements.

The Board recommends a vote FOR the approval of the Company’s executive compensation.

APPROVAL OF 2024 EQUITY INCENTIVE COMPENSATION PLAN

The Company has provided equity incentives to increase shareholder value and to attract, motivate, and retain the highest qualified employees and non-employee directors under the Company’s 2016 Equity Incentive Compensation Plan (the 2016 Equity Incentive Plan), which was adopted in 2016. The Board proposes to replace the 2016 Equity Incentive Plan with the 2024 Equity Incentive Compensation Plan (the 2024 Equity Incentive Plan), which would give the Board the continued ability to provide incentives through issuance of cash, stock, restricted stock, and other stock-based awards. As of the effective date of the 2024 Equity Incentive Plan, no further awards may be granted under the 2016 Equity Incentive Plan, but any existing awards under the 2016 Equity Incentive Plan will continue in effect in accordance with their terms and the provisions of the 2016 Equity Incentive Plan.

The following summary of the material aspects of the 2024 Equity Incentive Plan is qualified in its entirety by reference to the full text of the 2024 Equity Incentive Plan, a copy of which is set forth as Appendix A to this proxy statement. Unless otherwise specified, capitalized terms used in this discussion have the meanings assigned to them in the 2024 Equity Incentive Plan.

General

The 2024 Equity Incentive Plan provides for grants or awards of Restricted Stock, Restricted Stock Units, Performance Grants, and Other Stock Awards (collectively, Incentive Awards). The 2024 Equity Incentive Plan does not authorize grants of stock options or stock appreciation rights. Present and future employees of the Company and its subsidiaries and the Company’s Outside Directors are eligible to receive Incentive Awards under the 2024 Equity Incentive Plan. As of December 31, 2023, the Company and its subsidiaries had approximately 21,600 employees, and the Company currently has nine Outside Directors, eight of whom are being nominated for re-election at the 2024 Annual Meeting. The Compensation Committee of the Board has the power and complete discretion, as provided in the 2024 Equity Incentive Plan, to select eligible employees to receive Incentive Awards and to determine for each employee the nature of the award and the terms and conditions of each Incentive Award. The Outside Directors of the Board have the power and complete discretion to select Outside Directors to receive Incentive Awards for Outside Directors and to determine the terms and conditions, the nature of the award and the number of shares to be allocated as part of each Incentive Award for each Outside Director.

Stock Subject to Plan; Adjustments

The Board has reserved a total of (i) 250,000 new shares of Common Stock for use under the 2024 Equity Incentive Plan, plus (ii) any shares of Common Stock previously reserved for issuance under the 2016 Equity Incentive Plan that have not been issued and are not subject to outstanding awards under the 2016 Equity Incentive Plan as of the effective date of the 2024 Equity Incentive Plan, plus (iii) any shares previously reserved for issuance under the 2016 Equity Incentive Plan that are subject to outstanding awards under the 2016 Equity Incentive Plan as of the effective date of the 2024 Equity Incentive Plan which, after the effective date of the 2024 Equity Incentive Plan, expire, are forfeited, otherwise terminate or are settled in cash. As of December 31, 2023, there were approximately 86,144 shares of Common Stock previously reserved under the 2016 Equity Incentive Plan that have not been issued and are not subject to outstanding awards under the 2016 Equity Incentive Plan, and approximately 81,245 shares of Common Stock previously reserved under the 2016 Equity Incentive Plan that are subject to outstanding awards under the 2016 Equity Incentive Plan.

Shares necessary to satisfy awards under the 2024 Equity Incentive Plan may be newly issued shares or shares acquired in open market or private transactions. If an Incentive Award expires, terminates without a delivery of shares (e.g., the award is settled in cash) or results in the forfeiture of shares back to the Company, the shares subject to such award will become available for further awards under the 2024 Equity Incentive Plan. Shares exchanged by a Participant or retained by

9

the Company in payment of withholding taxes will not be available for future Incentive Awards under the 2024 Equity Incentive Plan. Shares issued under the 2024 Equity Incentive Plan through the settlement, assumption, or substitution of outstanding awards or obligations to grant future awards as a condition of acquiring another entity will not reduce the maximum number of shares available under the 2024 Equity Incentive Plan. In addition, the number of shares subject to the 2024 Equity Incentive Plan (and the number of shares and terms of any Incentive Award) may be adjusted if there is any change in the outstanding Common Stock by reason of any stock dividend, spin-off, split-up, stock split, reverse stock split, recapitalization, reclassification, merger, consolidation, liquidation, business combination or exchange of shares or similar transaction.

Limitations on Incentive Awards

No more than 50,000 shares of Common Stock may be allocated to Incentive Awards granted or awarded to any individual Participant during any 36-month period. No more than $250,000 worth of Incentive Awards (valued at the fair market value of the shares subject to the award as of the grant date) may be granted to any single non-employee director during any single calendar year.

Administration

The Compensation Committee of the Company’s Board, or a subcommittee of such committee (the Committee), administers the 2024 Equity Incentive Plan with respect to Incentive Awards to employees; and the Outside Directors of the Board administer the 2024 Equity Incentive Plan with respect to Outside Directors. Each member of the Committee or its subcommittee, which must have at least two members, must meet the standards of independence necessary to be classified as a non-employee director for purposes of Rule 16b-3 under the Exchange Act. Subject to the terms of the 2024 Equity Incentive Plan, the Committee or its duly-authorized delegate will have authority to determine the terms of Incentive Awards for employees and the Outside Directors will have authority to determine the terms of Incentive Awards for Outside Directors.

Restricted Stock and Restricted Stock Unit Awards

The 2024 Equity Incentive Plan authorizes the grant of Restricted Stock awards on terms and conditions established by the Committee or the Outside Directors, as applicable (the Applicable Administrator), which may include performance conditions. The terms and conditions will include the designation of a Restriction Period during which the shares are not transferable and are subject to forfeiture.

Restricted Stock Units may be granted on the terms and conditions established by the Applicable Administrator including conditioning the lapse of restrictions on the achievement of one or more performance standards. No shares are issued at the time of grant of Restricted Stock Units. Rather, upon lapse of the restrictions, a Restricted Stock Unit entitles a Participant to receive a share of Common Stock or a cash amount equal to the fair market value of a share of Common Stock on the date the restrictions lapse.

The minimum time-based vesting period for Restricted Stock and Restricted Stock Units is twelve consecutive months. For Restricted Stock and Restricted Stock Units that are subject to the attainment of performance goals, the minimum performance period is twelve consecutive months. Vesting may be accelerated upon death, Disability, Early Retirement, Retirement or a Change in Control.

Performance Grants

The Applicable Administrator may make Performance Grants to any Participant other than Outside Directors. Each Performance Grant will contain performance goals for the award established by the Committee, including the performance criteria to be used, the target and maximum amounts payable, and other terms and conditions.

The Committee will make all determinations regarding the achievement of performance goals. Actual payments to a Participant under a Performance Grant will be calculated by applying the achievement of the performance criteria or factors to the performance goal. Performance Grants will be payable in cash, shares of Common Stock or a combination of cash and shares of Common Stock.

Other Stock Awards

The 2024 Equity Incentive Plan authorizes the making of Other Stock Awards under which the Participant will become entitled to receive shares of Common Stock upon the satisfaction of the terms and conditions of the award. The

Applicable Administrator will establish the number of shares of Common Stock to be awarded and the terms and conditions applicable to each Other Stock Award, including any performance restrictions.

Change in Control

Unless otherwise provided in an Incentive Award, if, within twelve months after a Change in Control, a Participant is involuntarily terminated without Cause or terminates employment for Good Reason, or upon the occurrence of a Change in Control resulting in a complete liquidation or dissolution of the Company, (i) all restrictions on Restricted Stock will lapse, (ii) all Restricted Stock Units will be deemed fully vested, and (iii) all Performance Grants and Other Stock Awards will be deemed to be fully earned and vested, and each will be immediately issued or paid as the case may be; provided, that the level of attainment with respect to the Performance Awards will be based on the actual performance achieved through the date of the Change of Control.

Duration, Amendment and Termination

Unless sooner terminated by the Board, the 2024 Equity Incentive Plan will terminate on December 31, 2034. No Incentive Awards may be made under the 2024 Equity Incentive Plan after its termination.

The Board may amend the 2024 Equity Incentive Plan as it deems advisable, except that no change may be made that increases the total number of shares of Common Stock reserved for issuance under Incentive Awards unless such change is authorized by the Company’s shareholders (except as described above under Stock Subject to Plan; Adjustments). A termination or amendment of the 2024 Equity Incentive Plan will not, without the consent of the Participant, adversely affect a Participant’s rights under an Incentive Award previously granted.

Restrictions on Transfer; Deferral

Except as otherwise provided in the Incentive Award, Incentive Awards may not be transferred except by will or by the laws of descent and distribution. The Committee may permit Participants to elect to defer the issuance of Common Stock or the settlement of awards in cash under the 2024 Equity Incentive Plan.

U.S. Federal Income Tax Treatment of Awards under the 2024 Equity Incentive Plan

An employee or director will not incur federal income tax liabilities when granted any Incentive Award under the 2024 Equity Incentive Plan, unless the employee or director makes an election under Section 83(b) of the Code for a Restricted Stock grant. Unless the employee or director has made a Section 83(b) election, upon lapse of restrictions on Restricted Stock or upon the issuance of stock or cash under a Restricted Stock Unit or the payment of a Performance Grant or Other Stock Award, the employee or director will have ordinary income equal to the fair market value of the Common Stock and amount of cash received, as applicable.

The Company generally will be entitled to a business expense deduction at the time and in the amount that the recipient of an award recognizes ordinary income. Special rules limit the deductibility of compensation paid to certain employees. A participant who is an employee must pay or make arrangements with the Company for a sufficient amount to cover withholding of any federal, state or local taxes required by law. The Committee may permit shares to be used to satisfy required tax withholding, valued at the fair market value as of the settlement date of the applicable award.

New Plan Benefits

Any new benefits under the 2024 Equity Incentive Plan are determined by the Board in its discretion and are not determinable at this time.

The Board recommends a vote FOR this proposal.

SHAREHOLDER PROPOSAL FOR REPORT ON COMPANY GREENHOUSE GAS EMISSIONS

Green Century Capital Management (located at 114 State Street, Suite 200, Boston, MA 02109), beneficial owner of shares of the Company with a value in excess of $25,000 for at least one year as of November 30, 2023, intends to present the proposal set forth below at the 2024 Annual Meeting. The Company is not responsible for the content of the shareholder proposal.

Whereas: Climate change is creating systemic risks to the economy, and immediate, sharp emissions reductions are required. Companies lacking ambitious goals to cut greenhouse gas (GHG) emissions may jeopardize shareholder value for diversified investors, as climate change poses undiversifiable and unhedgeable risks.1

Markel is exposed to climate risk both as a long term investor in high-quality companies and as an insurance underwriter. In its most recent 10-K, Markel acknowledges that “If climate change results in an increase in the frequency and/or severity of weather-related catastrophes, we may experience additional or elevated catastrophe-related losses or disruptions, which may be material.”2 Regarding its casualty risk exposure, Markel states emphatically on its website that “Now is the time for the industry to wake up and start creating tools to prepare for potential systemic and clash events associated with climate change so that we will be prepared to face these risks head on.”3

It is consistent, then, that Markel has, in its words, “continued to support the insurance industry’s push for carbon neutrality as part of the Paris Climate Agreement.”

Yet, despite Markel’s acknowledgement of its climate risk, exhortations to address growing climate change-related casualty risk, and support for carbon neutrality, it fails to offer wholistic strategies that address its risk or align with its public statements. Markel additionally does not publish a comprehensive sustainability report, nor does it disclose emissions associated with its investments or underwriting.

Peer companies such as Travelers4 and AIG5 have started to disclose emissions associated with their investments, as have Swiss Re6, Munich Re7, Allianz8 and Aviva.9 Further, Swiss Re10 has begun to disclose its insurance associated emissions, and Aviva plans to do so as well.11

Markel could address investor concerns and take meaningful action by publishing a comprehensive sustainability report, similar those of its Fortune 500 peers. Moreover, the Company should begin the process of quantifying and disclosing the full range of its operational and value chain GHG emissions with the aim of setting an emissions reduction target aligned with the goals of the Paris Agreement of limiting temperature rise to 1.5 degrees Celsius.

RESOLVED: Shareholders request that Markel issue a report, at reasonable cost and omitting proprietary information, disclosing the GHG emissions from its underwriting, insuring, and investment activities.

SUPPORTING STATEMENT: In preparing report, we recommend, at management’s discretion:

•Taking into consideration GHG emissions disclosure guidance such as the GHG Protocol and Partnership For Carbon Accounting Financials Insurance-Associated Financials standard.

•As necessary Markel can initially base reporting on reasonable emissions estimates and provide a timeline for its disclosures.

THE BOARD UNANIMOUSLY RECOMMENDS THAT SHAREHOLDERS VOTE AGAINST THIS PROPOSAL FOR THE FOLLOWING REASONS:

The Board has carefully considered this proposal and does not believe that preparing and issuing a report disclosing the greenhouse gas emissions from the Company’s underwriting, insuring and investment activities is necessary or in the best interests of shareholders at this time for the reasons stated below:

•The Company’s business model appropriately considers and evaluates climate risks, and complying with the proposal’s request would be an unnecessary and inefficient use of Company resources. We confront climate change in the normal course of our business and consider climate risk as part of our ongoing underwriting activities. Climate risks related to our insurance operations are assessed and managed within our enterprise risk management program. To address the impacts of climate change, our insurance business works to identify, anticipate and address long-term risks and opportunities, including quantifying risks related to climate change and establishing an underwriting framework for management of this issue. Evaluating climate-related risks and opportunities is an important aspect of the underwriting and pricing of risks. In both our underwriting evaluation process and our underwriting strategies, we consider environmental factors, including weather trends and patterns, climate-related effects on weather perils, and other relevant risk variables. The Board believes that the proponent’s proposal would result in a competitive disadvantage to the Company.

While management is responsible for the day-to-day assessment, management and mitigation of climate risk, the Board is responsible for oversight of the Company’s risk management framework on an enterprise-wide basis, including the oversight of climate risks. Management regularly reports to the Board on risks. The Board believes that climate risks within the Company’s operations are being appropriately managed and monitored within the Company’s risk appetite. As a result, the Board believes that the proposal’s request would require an inadvisable use of significant management time and corporate resources that would not be in the best interests of shareholders.

•As a holding company, the Company’s culture and success depend on supporting, but not micromanaging, our numerous operating companies. Our businesses operate with a high degree of autonomy. Local management teams direct the day-to-day operations of their respective companies. We believe our business model allows managers to make decisions that are in the best interests of their employees and customers, as well as our shareholders. Consequently, the Board believes that climate and sustainability strategy, policies and programs should be addressed at the operating company level, with oversight by the Board.

•Measuring greenhouse gas emissions of the Company’s underwriting, insuring and investment activities in accordance with this proposal will be impractical, inaccurate and not an efficient use of shareholders’ investment in the Company. We do not believe we can accurately and reliably calculate the greenhouse gas emissions associated with our underwriting, insuring and investment activities in the manner described in the proposal. The Company underwrites and provides insurance and reinsurance worldwide for thousands of insureds from individuals and small businesses to Fortune 1000 companies. Our insurance-linked securities fund management operations provide insurance and investment management services for a broad range of investment products for insurance and reinsurance companies, government entities, banks, hedge funds, pension funds and institutional investors. The Company is not aware of any method by which we can accurately and reliably measure the GHG emissions of our insureds and the other customers/clients of our insurance operations. Similarly, we believe that reliable data necessary for the Company to accurately and reliably calculate the greenhouse gas emissions associated with the vast majority of our investment portfolio does not currently exist.

•The Company will comply with the SEC’s recently adopted climate disclosure rules when required. The SEC recently adopted rules requiring public companies in the United States to disclose climate-related risks and certain greenhouse gas emissions data, which are intended to, among other things, promote consistency, comparability, and reliability of climate-related disclosures. We are reviewing the SEC’s climate disclosure rules and assessing their

14

impact on the Company. We will comply with them when required. The Board does not believe it is responsible for the Company, or in the best interests of our shareholders, to commit to the proponent’s requested actions, particularly in light of the SEC finalizing its climate rules. We believe focusing on compliance with the SEC’s recently adopted climate disclosure rules will allow us to make informed and responsible decisions about the collection and disclosure of greenhouse gas emissions data, among other matters, as required by those rules. We believe that prioritizing compliance with SEC requirements is appropriate to avoid unnecessary, duplicative or potentially inconsistent reporting, and to prioritize Company efforts and allocate management time and corporate resources most effectively.

For the reasons stated above, the Board recommends a vote AGAINST this proposal.

If you sign and return your proxy (if voting by mail) or submit your proxy (if voting through the Internet or by telephone), but you do not provide a voting instruction on this proposal, your shares will be voted AGAINST the shareholder proposal.

Policy on Hedging and Pledging of Company Stock

The Board has adopted a hedging and pledging policy applicable to the Company’s executive officers and directors. The policy:

•prohibits any executive officer or director from purchasing financial instruments (including prepaid variable forward contracts, equity swaps, collars, and exchange funds), or otherwise engaging in transactions, that hedge or offset, or are designed to hedge or offset, any decrease in the market value of the Company’s equity securities (i) granted by the Company as part of the compensation of the executive officer or director or (ii) held, directly or indirectly, by the executive officer or director;

•prohibits any individual executive officer or employee director from entering into one or more pledge transactions covering shares of the Company’s equity securities in excess of 0.75% of the Company’s outstanding equity securities of that kind;

•prohibits any non-employee director from entering into any pledge transactions covering shares of the Company’s equity securities;

•stipulates that shares of the Company’s equity securities received as compensation by executive officers and directors may not be pledged; and

•stipulates that any shares pledged in violation of the policy will not be considered “owned” for purposes of the Company’s stock ownership guidelines.

Compliance with the policy is reviewed by the Nominating/Corporate Governance Committee on an annual basis. In February 2024, the Committee conducted a review of the policy and of the number of shares pledged by the Company’s executive officers and directors, the number of the Company’s outstanding shares and the Company’s 30-day average daily trading volume. The Committee acknowledged that, as descendants of Sam Markel, who in the 1930s formed the company that Anthony F. Markel and Steven A. Markel would later take public in 1986, it is not surprising that a significant portion of their net worth is held in the form of shares of the Company’s Common Stock. Pledging has enabled them to unlock a portion of the value of their stock without having to sell it. Within the constraints set forth in the policy, the Committee affirmed its support of this approach. The Committee reviewed the outstanding pledge balances, if any, of each of the Company’s executive officers and directors and confirmed the adequacy of and compliance with the policy.

K. Bruce Connell	Member	Member
Lawrence A. Cunningham			Member
Greta J. Harris			Member

Meetings and Attendance

In 2023, the Board and its committees held the following number of meetings:

Board/Committee	Number of Meetings
Board	6
Audit Committee	7
Compensation Committee	6
Nominating/Corporate Governance Committee	4

In 2023, each director attended at least 75% of the aggregate of (i) the total number of meetings held by the Board (during the period for which the director served as a director) and (ii) the total number of meetings held by all committees of the Board on which the director served (during the period(s) that the director served).

Corporate Governance Guidelines and Committee Charters

The Board has adopted Corporate Governance Guidelines and written charters for the Audit Committee, the Compensation Committee and the Nominating/Corporate Governance Committee. Current copies of the Guidelines and the written charters for each of these committees are available to security holders on the Company’s website, ir.mklgroup.com/investor-relations/governance.

Director Independence Determinations

The Board has determined that, of the current directors, Messrs. Besca, Connell, Cunningham, Housel, Morrison and O’Reilly and Mses. Harris, Leopold and Puckett are each “independent” of management under the categorical standards for determining independence adopted by the Nominating/Corporate Governance Committee. These categorical standards incorporate applicable independence rules of the New York Stock Exchange (NYSE). The Board also has determined that each member of the Audit Committee, the Compensation Committee and the Nominating/Corporate Governance Committee, respectively, meets applicable NYSE independence standards for service on those committees. In addition, each member of the Compensation Committee is a “non-employee director” for purposes of Rule 16b-3(b)(3) under the Exchange Act. No additional factors were identified that would impair any Compensation Committee member’s ability to make independent judgments about the compensation of the Company’s executive officers.

19

Under the categorical standards adopted by the Nominating/Corporate Governance Committee, a director is considered independent without further Board determination if the director meets NYSE standards, unless:

•The director is, or has been within the last three years, an employee of the Company, or an immediate family member is, or has been within the last three years, an executive officer, of the Company. Employment as an interim Chairman or Chief Executive Officer or other executive officer will not disqualify a director from being considered independent following that employment.

•The director has received, or has an immediate family member who has received, during any 12-month period within the past three years, more than $120,000 in direct compensation from the Company, other than director and committee fees and pension or other forms of deferred compensation for prior service (provided such compensation is not contingent in any way on continued service).

•The director is a current partner or employee of a firm that is the Company’s internal or external auditor; the director has an immediate family member who is a current partner of such a firm; the director has an immediate family member who is a current employee of such a firm and personally works on the Company’s audit; or the director or an immediate family member was within the last three years a partner or employee of such a firm and personally worked on the Company’s audit within that time.

•The director or an immediate family member is, or has been within the last three years, employed as an executive officer of another company where any of the Company’s present executive officers at the same time serves or served on that company’s compensation committee.

•The director is a current employee, or an immediate family member is a current executive officer, of a company that has made payments to, or received payments from, the Company for property or services in an amount which, in any of the last three fiscal years, exceeds the greater of $1,000,000, or 2% of such other company’s consolidated gross revenues.

•The director or an immediate family member is a current executive officer of a tax exempt organization that has received contributions from the Company in an amount which, in any of the last three fiscal years, exceeds the greater of $1,000,000, or 2% of such tax exempt organization’s consolidated gross revenues.

For these purposes: “Company” includes Markel Group Inc. and any of its consolidated subsidiaries; and “immediate family member” includes a person’s spouse, parents, children, siblings, mothers and fathers-in-law, sons and daughters-in-law, brothers and sisters-in-law, and anyone (other than domestic employees) who shares the person’s home.

Board Leadership Structure and Risk Oversight

Steven A. Markel has served as Chairman of the Board since May 2020.

Effective January 1, 2023, Mr. Gayner was appointed by the Board as sole Chief Executive Officer (CEO) of the Company and, with approval from the Board, assumed the functions, duties and responsibilities of the Company’s sole principal executive officer, after serving as Co-Chief Executive Officer of the Company since 2016 and co-principal executive officer since 2018. As CEO and a member of the Board, Mr. Gayner manages the day-to-day operations of the Company and formulates and implements the long-term strategic direction and initiatives of the Company (including the allocation of capital) in consultation with the other members of the Board.

The Company’s Corporate Governance Guidelines provide that continued Board membership of a former CEO of the Company is a matter to be decided in each individual instance, and that when a CEO resigns from that position, the CEO should offer to resign from the Board at that time.

The Corporate Governance Guidelines also provide for the designation of a Lead Independent Director by the Company’s non-employee directors. The Lead Independent Director presides at meetings of the non-employee directors and is responsible for communicating to the Chairman of the Board regarding the meetings. Mr. O’Reilly has served as Lead Independent Director since May 2021.

20

The Board and the Audit Committee are principally responsible for monitoring risk management by the Company. Management regularly reports to the Board and the Audit Committee on litigation risks, underwriting risks, operating risks, reserving issues, investment risks, cybersecurity risks, reinsurance and catastrophe risk management. Management also has established an enterprise risk management committee which periodically reports on its activities to the Board or the Audit Committee. In addition, management reviews with the Compensation Committee the design of the Company’s incentive compensation programs to assist in evaluating whether the programs might encourage the taking of excessive or unnecessary risks in order to earn incentive compensation.

The Board conducts an annual self-evaluation and has determined that both its processes and the performance of its functions were appropriate.

Executive Sessions

The non-employee directors (all of whom are independent) meet in executive session without management at each regularly scheduled Board meeting and at such other times as the non-employee directors deem appropriate.

Communications with Directors

Any security holder or other interested party wishing to communicate with the Board as a whole, the non-employee directors or an individual director should write to “Board of Directors,” “Non-Employee Directors” or the individual director in care of the Company Secretary at 4521 Highwoods Parkway, Glen Allen, Virginia, 23060. Communications from security holders or other interested parties addressed in this fashion will be sent directly to the Board, the non-employee directors or the individual director, as applicable.

Compensation of Non-employee Directors

Annual Retainer Fee

Upon election to the Board, each non-employee director is paid an annual retainer fee of $110,000 (or a pro-rated portion thereof if elected to the Board after the annual meeting of shareholders). The Lead Independent Director, Mr. O’Reilly, also receives an additional annual retainer fee of $30,000. The retainer fee is paid in cash, except to the extent the director chooses to receive the fee in the form of shares of the Company’s Common Stock. In addition, each non-employee director is reimbursed for expenses incurred in connection with attending meetings.

In 2023, non-employee directors were eligible to participate, up to the total amount of the retainer fees received by the director, in the Non-Qualified Component of the 2020 Stock Purchase Plan (as defined below under “Employee Stock Purchase Plan”). Under the Non-Qualified Component, non-employee directors have the ability to purchase the Company’s Common Stock at a 10% discount. In 2023, Messrs. Besca, Cunningham, Housel and O’Reilly and Mses. Leopold and Puckett elected to receive their entire retainer fees, and Mr. Morrison elected to receive half of his retainer fee, in the form of shares of the Company’s Common Stock purchased under the 2020 Stock Purchase Plan.

21

Annual Restricted Stock Award

Upon election to the Board, each non-employee director also receives an annual grant of restricted stock valued at approximately $165,000 (or a pro-rated portion thereof if elected to the Board after the annual meeting of shareholders), calculated based on the fair market value of the Company’s Common Stock on the grant date and rounded up or down to the nearest whole share.

Stock Ownership Guidelines

The Company places a strong emphasis on equity ownership by executive officers and other members of senior management and has extended that philosophy to its Board by adopting stock ownership guidelines for non-employee directors. The guidelines require non-employee directors to acquire and maintain ownership of Common Stock with a value at least equal to five times the annual cash retainer paid. Following an increase in the ownership requirement due to an increase in the annual cash retainer paid, the non-employee directors have five years to comply with the additional ownership expected to be held due to the annual cash retainer increasing. All shares acquired under the 2020 Stock Purchase Plan count toward ownership requirements along with any restricted stock granted but not vested. Purchased shares are valued at the higher of cost to the director or market. All current non-employee directors meet the guideline requirements.

Audit Committee

The purpose of the Audit Committee is to assist the Board in fulfilling its oversight responsibilities with respect to: (i) the integrity of the Company’s financial statements; (ii) the Company’s compliance with legal and regulatory requirements; (iii) the independent auditors’ qualifications and independence; and (iv) the performance of the independent auditors and the performance of the Company’s internal audit function. In addition, the Committee provides an avenue for communication between the internal auditors, the independent auditors, financial management and the Board. The Committee meets in executive session at each of its regularly scheduled meetings, meeting privately with the independent auditors, key members of management and the Managing Director of Internal Audit. The Committee conducts an annual self-evaluation and has determined that both its processes and the performance of its functions were appropriate.

The Board has determined that all members of the Audit Committee are financially literate, and that Messrs. Besca and O’Reilly are “audit committee financial experts” as defined by Item 407(d) of Regulation S-K under the Exchange Act. In making these determinations, the Board considered, among other things, the experience described under “Election of Directors” above and other relevant experience as summarized below:

22

Mr. Besca - As a senior executive of EY (formerly Ernst & Young, LLP), he has thirty years experience serving as a lead and senior advisory audit partner of Fortune 500 companies in the Media and Entertainment, Consumer Products and Airline industries. He brings a broad array of skills and expertise to the Committee from his many years of advising major corporations across a number of industries.

Mr. Connell - As Executive Vice President and Group Underwriting Officer of XL Capital Ltd. as well as chief executive and underwriter at various subsidiaries and predecessors to XL Capital Ltd., he has thirty years experience of combined insurance and financial expertise.

Mr. Morrison - He has over thirty years of combined insurance, administrative and financial experience. Mr. Morrison served as Senior Vice President, Chubb Group, and Division President, Field Operations, North America Insurance of Chubb Insurance Company, after previously serving in several other senior executive management positions at Chubb. He is a proven industry leader, who brings deep administrative and operational experience on a global level to the Committee.

Mr. O’Reilly - He served as Chief Financial Officer of Chubb Corporation for six years after having previously served as Chief Investment Officer. Mr. O’Reilly’s combination of insurance and financial experience is a valuable asset to the Committee.

Compensation Committee

The Compensation Committee is appointed by the Board to, among other things: (i) review and approve corporate goals and objectives relevant to compensation for the Company’s executive officers; (ii) review and evaluate the performance of the CEO and the Company’s other executive officers in light of such goals and objectives and, based on these evaluations, determine and approve their annual and long-term compensation; (iii) administer the Company’s incentive stock plans; and (iv) review and approve, or recommend to the full Board, executive incentive compensation plans and equity-based plans in which the Company’s executive officers and members of the Board are eligible to participate. The Committee also discusses succession planning regarding the CEO, the Company’s other executive officers, and certain specified key executives of the Company’s operating companies, and periodically reports its views on succession to the full Board, giving due consideration to succession in the event of an emergency or unanticipated retirement of any of these employees. The Committee conducts an annual self-evaluation and has determined that both its processes and the performance of its functions were appropriate.

The Compensation Committee has full authority over compensation of the executive officers of the Company. This authority is not delegated to any other person.

The Committee annually reviews and, if appropriate, resets the compensation of the Company’s executive officers taking into account, among other factors, level of experience; individual areas of responsibility; the Company’s operating performance; and total compensation opportunities relative to compensation opportunities of other members of management of the Company and its subsidiaries. The Committee considers recommendations from senior management in the course of its review.

In 2023, senior management engaged an outside compensation consultant, Compensation Advisory Partners LLC (CAP), to provide current market research and analyses against which executive compensation programs and proposals could be evaluated. Senior management worked with CAP to make recommendations regarding executive compensation that are consistent with the Company’s objectives. CAP reported directly to senior management and, in turn, senior management presented data, analysis and recommendations to the Compensation Committee for review and consideration. CAP did not engage directly with the Compensation Committee or the Board. For additional information regarding senior management’s engagement with CAP, see “Compensation Setting Process” below.

For 2023, the aggregate fees paid to CAP for its advice and recommendations on the amount and form of executive compensation was $184,300.

The Committee has authority to retain, appoint, compensate and oversee the work of compensation advisers and require the Company to provide reasonable compensation to such advisers as determined by the Committee. Neither the Committee nor the Board has retained compensation consultants to assist it in determining the amount or form of compensation for executive officers or directors. When applicable, the Committee will conduct independence assessments of compensation advisers who provide advice to the Committee in accordance with the independence factors established by the NYSE, as then in effect.

The Committee also reviews and assesses the compensation paid to non-employee members of the Board and recommends to the Board any changes the Committee believes are appropriate.

23

Nominating/Corporate Governance Committee

The Nominating/Corporate Governance Committee is appointed by the Board to: (i) identify individuals qualified to become Board members; (ii) assist the Board in reviewing the independence, skills and characteristics of Board members, as well as the size, composition and leadership structure of the Board and its Committees; (iii) recommend to the Board the director nominees for the next annual meeting of shareholders and to fill any vacancies on the Board; (iv) recommend to the Board nominees for each committee of the Board; and (v) oversee the governance of the Company, including recommending to the Board a set of corporate governance guidelines for the Company.

While the Committee has not adopted minimum criteria, it considers several qualifications when considering candidates for the Board. The Committee seeks a mix of skills and experience on the part of Board members that will maximize the Board’s effectiveness. Among attributes the Committee takes into account are: integrity; leadership and policy making experience; business and financial expertise; government or community service; diversity of experience, background and perspectives; and the ability to act in the best interests of all shareholders. None of the attributes is given any particular weight in selecting a candidate. The Committee does not have a policy with respect to director diversity, but considers diversity, in its broadest sense, in selecting candidates who have a mix of experiences, backgrounds and perspectives that will enhance the quality of the Board’s interactions and decisions. The Committee also seeks to have candidates with a diversity of backgrounds, perspectives and experience that complement the backgrounds, perspectives and experience of others on the Board. Director candidates should be committed to representing the long-term interests of all of the shareholders and should not have any interests that conflict with service with the Company. In addition, directors must be willing to devote sufficient time to carrying out their duties and responsibilities effectively, and should be committed to serve on the Board for an extended period of time. The Committee conducts an annual self-evaluation and has determined that both its processes and the performance of its functions were appropriate.

The Committee will consider candidates recommended by shareholders for consideration as directors on the same basis it evaluates other candidates. Any shareholder wishing to recommend a candidate for consideration should write to the Chair of the Nominating/Corporate Governance Committee in care of the Company Secretary at 4521 Highwoods Parkway, Glen Allen, Virginia, 23060. See “Shareholder Proposals” below for requirements that must be met for including a director nominee in the Company’s proxy materials for the 2025 Annual Meeting of Shareholders or for nominating a director at the 2025 Annual Meeting of Shareholders.

Code of Conduct

The Board has adopted a Code of Conduct that is applicable to all directors and employees, including the Company’s principal executive, financial and accounting officers. The Company has posted the Code of Conduct on its website, ir.mklgroup.com/investor-relations/governance. The Company intends to satisfy applicable disclosure requirements regarding an amendment to, or waiver from, a provision of the Code of Conduct that applies to the Company’s principal executive, financial and accounting officers, by posting such information on its website, ir.mklgroup.com/investor-relations/governance.

Review of Transactions with Related Persons

The Board has adopted a written Related Party Transactions Policy pursuant to which the Nominating/Corporate Governance Committee is responsible for conducting a reasonable prior review of all related party transactions for potential conflicts of interest. The Committee must prohibit a transaction if it determines the transaction to be inconsistent with the interests of the Company and its shareholders. Under the policy, a related party transaction is a transaction required to be disclosed pursuant to Item 404 of Regulation S-K under the Exchange Act.

In addition to the Related Party Transaction Policy, executive officers and directors must also comply with the Company’s Code of Conduct. Under the Code of Conduct, executive officers and directors should avoid actual or apparent conflicts of interest, and any potential conflict of interest or waiver that involves an executive officer or director must be approved by the Board or the Nominating/Corporate Governance Committee.

Certain Transactions

Anthony F. Markel and Steven A. Markel are directors and employees of the Company. In 2023, total compensation for them as employees was approximately $276,000 and $277,174, respectively. They did not receive any compensation for

24

their service as directors of the Company. The Company also made charitable contributions in the amounts of $15,000 each to match contributions made by Mr. Anthony Markel and Mr. Steven Markel in 2023.

Mr. Gayner’s spouse retired as President and Chief Executive Officer of a Company subsidiary in 2022, and in 2023 she had a consulting arrangement with that and another Company subsidiary. In 2023, total compensation to Mr. Gayner’s spouse was approximately $157,500.

Andrew G. Crowley, the Company’s President, Markel Ventures, is the son of F. Michael Crowley, a former Vice Chairman of the Company, who is party to an ongoing consulting arrangement with the Company. The consulting arrangement runs from January 1, 2019 through December 31, 2024, and automatically renews for additional 1-year periods unless terminated by either party. In 2023, total compensation to Mr. F. Michael Crowley was $112,500.

Corporate Responsibility

The Markel Style

Markel Group Inc. is a diverse financial holding corporation serving a variety of niche markets. At Markel Group, our culture is our greatest asset and is defined by the Markel Style, a timeless statement of our values and mission that is woven into our corporate DNA. The Markel Style provides a roadmap as we strive to build an enduring organization. Within this roadmap are principles on how we interact with our stakeholders. We seek to know our customers’ needs and to provide our customers with quality products and services. We provide an atmosphere in which people can reach their personal potential and work in a spirit of teamwork. We pledge to our shareholders we will build the financial value of their company. We respect our suppliers, and we have a commitment to our communities. The Markel Style was written in 1986 and remains our guidepost today.

Key within the Markel Style is the encouragement to look for a better way to do things, to challenge management. We also seek spontaneity and flexibility and a respect for authority, but disdain for bureaucracy. Our diverse financial holding company is managed in a way to accomplish these principles. Each of our businesses operates with a high degree of autonomy so long as they operate within the principles of the Markel Style. This allows our managers to make decisions that are best for their employees, customers, and communities, as well as our shareholders.

Insurance

We illustrate in further detail in the paragraphs below a variety of the ways in which Markel, our insurance business underwrites specialty insurance products consistent with the Markel Style.

Our people

We have a well-developed performance-management process, which is conducted in close coordination with our multiple levels of management and leadership development training. We also encourage employees within our Markel insurance operations to own their career development by taking advantage of training offered through our Workday Learning platform, as well as through courses and programs outside of Markel that are offered through professional organizations, academic institutions, and similar organizations. We also have undertaken significant work over recent years to establish global leadership development programs for different levels of leadership at Markel, including partnering with various renowned business schools to create leading-edge curricula in this area.

With the Markel Style as our foundation, we have identified five pillars of focus that relate to today’s challenges and opportunities—diversity and inclusion, community, innovation, well-being, and recognition. This program is both company and employee led—collectively, we want to bring the values of the Markel Style to life with our actions, not just our words. Our intent is to create an environment where employees are able to authentically bring their true selves to work, a place where all ideas are heard and diverse perspectives are valued, a culture that prioritizes innovation, the ability to make a

25

difference for our local communities and the wider world, and a foundation for holding ourselves accountable for our own well-being and of those around us.

Employee health and overall well-being is also a key priority, and we provide a range of employee and eligible partner plans and programs, including health and voluntary benefits, within our insurance operations. These offerings include a variety of financial protection programs to help our employees meet their unique investment and savings needs including life insurance, retirement savings with company contributions in most situations and an employee stock purchase plan. Comprehensive employee assistance programs are available in all our major markets along with other well-being and fitness resources, including an employee led Global Wellbeing Network.

We rely on our employees’ ideas and input to help make Markel a great place to work. For example, senior leadership conducts regular employee communications meetings along with question and answer sessions across Markel providing opportunities for employees to share their ideas on how we can improve employee engagement. In addition, every two years we conduct a major, global employee engagement survey within our insurance operations, which in early 2022 garnered 88% participation, and which enables us to identify, focus on and track progress against key engagement drivers and external norms for high performing companies. This survey has generated additional ideas for employee engagement; and we have made substantial changes and improvements in our human capital practices based on this feedback. Plans are underway to conduct an employee engagement survey in early 2024. Additionally, Markel conducts regular pulse and employee net promoter score surveys on a departmental level across the organization throughout the year.

We are committed to embracing all aspects of diversity, including diversity of perspective, which we believe is crucial to sustainable success. Markel accordingly supports and encourages focused efforts to continue to build the diversity of our employee population and the inclusiveness of our culture. Our diversity and inclusion efforts seek to cultivate an inclusive environment in which every employee feels valued, respected and accepted. We believe this environment helps us increase creativity and innovation, foster business connections, serve our customers and maintain our market leadership.

Within Markel, our global Diversity and Inclusion (D&I) Steering Committee comprises more than 15 senior managers who are charged with advising on D&I strategy and providing leadership support and advocacy for our D&I efforts. We have an overarching D&I strategy, focusing on our diverse workforce, our inclusive workplace and market connectivity, and annual priorities are agreed and shared with leaders. Our human resources (HR) leadership team works to further shape the D&I strategy for our global workforce and to ensure the integration of our D&I efforts with our global talent acquisition and development processes. We have various early career programs open to a diverse range of applicants and a regional scholarship program that is focused on underrepresented groups.

Markel supports a range of employee-led D&I networks and resource groups, including our Markel Women’s Network, BEAM (Black Engagement at Markel), PRISM (LGBTQ+), Jitneys (Young Professionals), Markel Asian Professionals Network, Markel Veterans Network, UN1DOS (Latin and Hispanic Network), and across our international operations, an Inclusion Network with connections to a number of the London market partner networks. All of these networks and organizations have put in place goals and programming that are focused on education and development, community engagement, talent acquisition and networking/support. In addition we continue our global sponsorship of Dive-In, the insurance industry’s annual diversity and inclusion festival.

Our communities and environment

On the Company responsibility section of the Markel website, you will find information about our continued commitment to the communities where our employees and customers live and work. Together with our employees, Markel has a strong tradition of supporting community-based, national, and international organizations whose missions align with the Markel Style. In 2023, Markel supported over 1,000 organizations across the globe through employee and company giving. Markel donations were made to more than 245 different non-profits worldwide. The Markel matching gift program saw a 6% increase in employee participation. This program matches employee contributions 3 to 1, up to $4,500, in most instances. Additionally, Markel has a Volunteer Time Off program that allows employees time off to do volunteer service in the community. In 2023, employees logged over 4,000 volunteer hours through either Markel’s Dollars for Doers segment of the Matching Gifts program or paid Volunteer Time Off programs. Also, in 2023, Markel introduced the Sam Markel Days of Service to honor the philanthropic legacy of founder Sam Markel. Throughout the month of April, employees across the globe volunteered for more than 60 events, providing over 1,200 hours of service for their local communities.

At Markel, we evaluate both the risks and opportunities related to the impact of the environment on our underwriting and insurance-linked securities activities. To address the impacts of climate change, our insurance business works to identify, anticipate and address long-term risks and opportunities, including quantifying risks related to climate change and establishing an underwriting framework for management of this issue. As part of our underwriting model, which follows a

26

principles-based approach, we work with a number of brokers and insureds to help achieve the transition to a lower-carbon energy economy. As an example, for more than a decade, we have been underwriting insurance for renewable energy providers in a number of our product lines, including Casualty and Commercial Directors & Officers, insuring green and/or sustainable risks and working to develop new products to support the growth of their industry. We also support our clients through Nephila, our insurance-linked securities operations. Among other things, Nephila’s climate focused division has developed solutions to reduce the financial impacts from climate volatility and facilitated renewable projects aimed at progressing energy transition through innovative risk transfer products.

Our information security and data protection governance

Markel recognizes the utmost importance of a strong information security and data protection program to protect the confidentiality, integrity, and availability of data that we own and hold. Within our insurance operations,1 the Markel information security and data protection program is led by a Chief Information Security Officer (CISO) who supervises a team of information security and data protection professionals across the globe. Markel’s global information security program leverages the Cybersecurity Framework from the National Institutes of Standards and Technology as well as industry best practices. Markel is also able to map to both ISO (International Organization for Standardization) and BSI (British Standards Institution) among other cybersecurity standards. In partnership with our legal department, the global data protection program provides privacy notices to customers, employees, and other stakeholders regarding how Markel safeguards and uses personal information. Both programs are designed to comply with applicable laws and regulations.

In order to maintain a strong program, Markel uses a variety of controls and technology tools designed to identify, detect, prevent, respond to and recover from security threats. Markel regularly tests aspects of our internal security, and we conduct security risk interviews and assessments on third parties with whom we do business, depending on the nature of the relationship. The Company undergoes regular security audits. The CISO participates as part of the Company’s Enterprise Risk Management group where information security risks and mitigation strategies are discussed. The CISO also updates the Board on information security matters. Markel participates in the Financial Services Information Sharing and Analysis Center to share information about the latest cyber threats and preparedness measures. Markel also shares threat intelligence information with other partners. Markel has an Incident Response Plan, as well as a Crisis Management Plan, that cover cyber events. An internal team engages in tabletop exercises several times per year in order to enhance preparedness for such situations.

Over the last three years, Markel has not experienced any material information security breaches. Therefore, net expenses, penalties and settlements incurred from information security breaches have been insignificant relative to total revenue. Markel believes that information security and data protection risks are the responsibility of all employees and our Code of Conduct specifically requires employees to maintain the confidentiality of information. Markel has a mandatory training program covering all information security and data protection disciplines. In addition, Markel distributes annually to all insurance operation employees policies on acceptable use and enterprise information security. Contractors are required to provide certain representations and certifications relating to information security.

Corporate governance

At Markel Group, in 2023, we continued to build on our strong governance practices.

Board Depth and Diversity. Three (or 25%) of our current directors identify as female and two (or 17%) identify as Black or African American.

COMMITTEE REPORTS

Report of the Audit Committee

In performing its oversight role, the Audit Committee has reviewed and discussed the audited financial statements with management and KPMG LLP. The Audit Committee also has discussed with KPMG the matters required to be discussed by Public Company Accounting Oversight Board Auditing Standard No. 1301, Communications with Audit Committees; has received the written disclosures and the letter from KPMG required by applicable requirements of the Public Company Accounting Oversight Board regarding KPMG’s communications with the Audit Committee concerning independence; and has discussed KPMG’s independence with KPMG. The Audit Committee has considered whether the provision of non-audit services (none of which related to financial information systems design and implementation) by KPMG is compatible with maintaining independence and has discussed with KPMG its independence. Based on the review and discussions described in this Report, and subject to the limitations on its role and responsibilities described below and in its charter, the Audit Committee recommended to the Board that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

The Audit Committee performs the oversight role assigned to it by the Board in its charter. Management, under the oversight of the Audit Committee, is responsible for the preparation, presentation and integrity of the Company’s financial statements, accounting and financial reporting principles, internal controls and procedures as well as the establishment and maintenance of programs and controls designed to prevent, deter and detect fraud, all designed to assure compliance with accounting standards and applicable laws and regulations. The independent registered public accounting firm is responsible for expressing an opinion about whether the financial statements that have been prepared by management with the oversight of the Audit Committee are presented fairly, in all material respects, in conformity with generally accepted accounting principles in the United States (U.S. GAAP). The independent registered public accounting firm is also responsible for expressing an opinion about whether the Company maintained, in all material respects, effective internal control over financial reporting based on established criteria. The applicable established criteria are those in the Internal Control - Integrated Framework (2013) issued by COSO (the Committee of Sponsoring Organizations of the Treadway Commission). These audits are conducted in accordance with the professional standards of the Public Company Accounting Oversight Board. The members of the Audit Committee rely without independent verification on the information provided to them and on the representations made by management and the independent registered public accounting firm. Accordingly, the Audit Committee’s oversight does not provide an independent basis to determine that the Company’s financial statements have been prepared in accordance with generally accepted accounting principles or that the audit of the Company’s financial statements has been carried out in accordance with the standards of the Public Company Accounting Oversight Board (United States).

COMPENSATION DISCUSSION AND ANALYSIS

The Company’s business model builds shareholder value over the long term by generating (i) earnings from our insurance operations, including underwriting profits, (ii) investment returns from our fixed income and equity portfolios, and (iii) earnings from our ownership interests in a diverse portfolio of businesses that operate in a variety of industries. The Company’s objective is for its employees, including the Company’s executive officers, to earn market competitive base salaries and benefits, and to varying degrees based on career level, have the opportunity to earn significant incentives based on short and long-term performance. The Company also places a strong emphasis on equity ownership, with the expectation that this results in employees thinking and managing the business like owners.

Compensation Philosophy

The Company’s current compensation philosophy is informed by our management philosophy, supplemented by on-going review of developments and trends in executive compensation practices and design. The Markel Style, a spirit of innovation, excellence, and teamwork, is the foundation of our way of working. Among other things, this involves trust and respect for the abilities of fellow decision makers, challenging the status quo and looking for better ways of doing things.

Our compensation framework and its intended purpose is based on the following principles and objectives:

•Long-Term Perspective: Our overriding perspective is a long-term one, and correspondingly we believe in using performance metrics based over a multi-year period to incent long-term decision making and the creation of shareholder value.

•Ownership Mentality: We believe granting performance-based incentive compensation in the form of Restricted Stock Units (RSUs) to senior leaders including all executive officers using multi-year performance metrics aligns their interests with those of our shareholders. We also expect executive officers to amass and maintain a meaningful amount of stock ownership in the Company.

•Pay for Performance: Our compensation programs are designed to incent and reward superior performance. Payouts under the various programs vary with performance against annual Company goals, individual objectives and long-term metrics. We believe that performance-based incentive compensation should comprise the vast majority of executive officer target compensation. Significant differentiation of reward based on performance levels is strongly encouraged across the Company.

•Industry Competitive: Total rewards must be competitive in the markets where we compete for talent in order to attract, motivate, reward and retain high quality individuals at all levels. Compensation should fairly reflect an employee’s level of responsibility, authority and contribution.

•Global standards: In support of the global nature of our business, our compensation frameworks and programs are designed to provide alignment and integration across the geographies in which we operate.

The following discussion summarizes our executive compensation setting process and examines each of the key elements of compensation, how they are determined, and how they fit within the overall compensation structure.

Compensation Setting Process

The Compensation Committee annually reviews and, if appropriate, resets the compensation of the Company’s executive officers. The Compensation Committee has not retained a compensation consultant to assist it in determining appropriate compensation levels and has not engaged in any formal benchmarking processes. The Committee has instead relied on the general knowledge, experience, and good judgment of its members, both with regard to competitive compensation levels and the relative success that has been achieved by the Company, as well as information available to the members of the Compensation Committee from sources both within and outside the Company, including data, analysis and recommendations presented by senior management in consultation with an outside compensation consultant engaged by senior management. In addition, the Compensation Committee takes into account, among other factors: level of experience; individual areas of responsibility; the Company’s operating performance; and total compensation opportunities relative to compensation opportunities of other members of management of the Company and its subsidiaries.

In 2023, senior management engaged Compensation Advisory Partners LLC (CAP) as a compensation consultant to management to provide current market research and analyses against which executive compensation programs and proposals could be evaluated. Senior management worked with CAP to make recommendations to the Compensation Committee regarding executive compensation that are consistent with the Company’s objectives. CAP shared market data with senior

29

management, and, in turn, senior management presented data, analysis and recommendations to the Compensation Committee for review and consideration. CAP did not engage directly with the Compensation Committee or the Board.

Each year, management provides the Compensation Committee with updated market information for each executive officer’s compensation. The market information is based on a peer group, which is discussed further below. The peer group data, including data drawn from proxy statement disclosures for named executive officers and survey data for other executives, is used to create percentile comparisons for each executive’s base salary, total cash compensation (base salary plus annual cash incentives) and total direct compensation (base salary plus annual cash incentives plus all long-term incentive awards). The Compensation Committee considers this peer group information as part of its assessment of any proposed adjustments to executive compensation.

With input and recommendations from CAP, senior management identified a peer group of 22 companies for use in connection with developing recommendations for the Compensation Committee for compensation practices, design and pay levels for 2023. This peer group, set forth below, was presented to the Compensation Committee.

Aflac	Everest Re Grp.
Alleghany Corp.	Fairfax Financial Holdings
American Financial Grp.	Fidelity National Financial
Aon	Hartford Financial Services
Arch Capital Group	Illinois Tool Works
BlackRock	Jefferies
Chubb Ltd.	KKR & Co.
Cincinnati Financial Corp.	Loews Corp.
CNA Financial Corp.	Marsh & McLennan
Danaher Corp.	The Carlyle Group
Dover Corp.	W. R. Berkley Corp.

Factors considered in determining this peer group included:

•Balancing the peer group with an appropriate mix of property and casualty (P&C), multi-line insurance, reinsurance, and multi-sector holding companies;

•Including broader market multi-industry companies (i.e., conglomerates/holding companies, capital allocators); and

•Identifying companies with similar business mix and model, revenues and market capitalization within an appropriate range.

Peer group data is only one of many factors the Compensation Committee considers in determining executive compensation. Neither senior management, nor the Compensation Committee, targets a specific percentile for any element of compensation or for total compensation, nor does senior management, or the Compensation Committee, target any particular mix of base salary, annual cash incentive compensation, and long-term equity incentive compensation. Management occasionally provides the Compensation Committee with additional relevant market information, such as emerging compensation trends or the type and prevalence of incentive metrics.

For 2024, management recommended, and the Compensation Committee approved, modifying the peer group by removing Aflac Incorporated, Alleghany Corporation, BlackRock, Inc., Cincinnati Financial Corporation, CNA Financial Corporation and Jefferies Financial Group Inc.

Base Salary and Benefits

In general, base salary levels for our executive officers are set by the Compensation Committee at levels believed to be sufficient to attract and retain qualified executives when considered with other components of the Company’s compensation structure.

The named executive officers, as identified under “Executive Compensation” below, are Thomas S. Gayner, CEO; Michael R. Heaton, Executive Vice President and Chief Operating Officer; Jeremy A. Noble, President, Insurance;

30

Richard R. Grinnan, Senior Vice President, Chief Legal Officer and Secretary; Brian J. Costanzo, Chief Financial Officer (who served as principal financial officer on an interim basis from January 1, 2023 to March 20, 2023, and as Chief Financial Officer beginning December 18, 2023); and Teresa S. Gendron, former Chief Financial Officer (who served in that capacity from March 20, 2023 to December 18, 2023).

In recognition of the value of their contributions and the importance of fairly and appropriately incenting them, and in connection with changes in the Company’s leadership and organizational structure, the Compensation Committee approved, with effect in 2023, base salary increases for Messrs. Heaton, Noble, Grinnan, and Costanzo, as follows:

			Annual Base Salary At December 31, 2023
Name	Effective Date	Salary Increases
Michael R. Heaton	1/1/2023	$125,000	$775,000
Jeremy A. Noble	1/1/2023	$125,000	$775,000
Richard R. Grinnan	2/20/2023	$50,000	$600,000
Brian J. Costanzo	*	$150,000*	$500,000
* Mr. Costanzo’s salary increases included: (i) $10,500, effective February 20, 2023, in connection with changes in leadership and the Company’s organizational structure; (ii) $64,500, effective December 1, 2023, in connection with his appointment as Chief Financial Officer, Insurance; and (iii) $75,000, effective December 18, 2023, in connection with his appointment as the Company’s Chief Financial Officer.

The Company offers a competitive package of employee retirement and welfare benefits, in which executive officers participate on the same basis as other salaried employees. The Company’s Retirement Savings Plan is a defined contribution plan qualified under Sections 401(a) and 401(k) of the Internal Revenue Code of 1986 (the Code). Excluding Ms. Gendron, each of the other named executive officers participated in the plan in 2023 and received the maximum Company contribution under the plan of $29,700 for the year. Other than the Deferral Plan described below, there is no supplemental benefit plan for executive officers with respect to the Retirement Savings Plan or any employee welfare plan. See “Compensation for Teresa S. Gendron” below for discussion of Ms. Gendron’s base salary.

Deferral Plan

In November 2015, the Board, upon the recommendation of the Compensation Committee, adopted The Markel Corporation Voluntary Deferral Plan (as amended, the Deferral Plan), which became effective April 1, 2016. Subsequently, the Board, upon recommendation of the Compensation Committee, adopted amendments to the Deferral Plan, which became effective January 1, 2019 and January 1, 2020, respectively. The Deferral Plan is an unfunded, non-qualified deferred compensation plan maintained for the benefit of a select group of management or highly compensated employees of the Company, including the Company’s named executive officers. Below is a brief description of the terms and conditions of the Deferral Plan.

The Deferral Plan is an account-based plan that allows participants to defer voluntarily the payment of current compensation to future years. The Deferral Plan permits each participant to defer up to 30% of base salary and up to 75% of any annual cash award and performance-based cash compensation, which amounts would be credited to an account established for the participant under the Deferral Plan. The amounts credited to a participant’s account will always be fully vested.

Amounts credited to a participant’s account will be indexed to one or more deemed investment alternatives chosen by the participant from a range of alternatives available under the Deferral Plan. Each participant’s account will be adjusted to reflect gains and losses based on the performance of the selected investment alternatives. A participant may elect to receive distributions from the Deferral Plan: (1) upon separation from service, in a lump sum or annually through installment payments over three, four, or five years; (2) when a participant reaches a certain age, in a lump sum or annually through installment payments over five, ten, or fifteen years; or (3) on dates specified by the participant, in a lump sum or annually through installment payments over five, ten, or fifteen years. The participant’s distribution election regarding in-service payments will be subject to override upon the participant’s death with a lump sum payment. There will be a six month delay for commencement of a payment upon termination of employment to any “specified employee” as defined under Internal Revenue Code Section 409A.

The Compensation Committee is the administrator of the Deferral Plan.

There were no cash amounts paid to any named executive officer under the Deferral Plan for 2023.

Employee Stock Purchase Plan

In 2023, the Company offered its employees and non-employee directors the opportunity to participate in the Company’s 2020 Employee Stock Purchase Plan (the 2020 Stock Purchase Plan). The plan includes a component that is intended to qualify as an “employee stock purchase plan” under the Internal Revenue Code (the Qualified Plan Component), in addition to a component that does not qualify as an “employee stock purchase plan” under the Internal Revenue Code (the Non-Qualified Plan Component). The 2020 Stock Purchase Plan offers employees and non-employee directors the ability to purchase our Common Stock through payroll deductions or lump-sum payments, as applicable, at a discount (a 15% discount under the Qualified Plan Component and a 10% discount under the Non-Qualified Plan Component). As noted above, non-employee directors are only eligible to participate in the Non-Qualified Plan Component to the extent they elect to receive all or a portion of their annual retainer fee in shares of Common Stock.

Incentive Compensation

The Company’s incentive compensation program for executive officers generally consists of two elements-annual cash incentive compensation paid under the Executive Bonus Plan (the Non-Equity Incentive Plan) and RSUs issued under the 2016 Equity Incentive Compensation Plan (the 2016 Equity Incentive Plan). All executive officers participated in the Non-Equity Incentive Plan (other than Mr. Costanzo) and were eligible to receive RSUs for 2023 performance.

Awards to the named executive officers under both the Non-Equity Incentive Plan (other than Mr. Costanzo) and the 2016 Equity Incentive Plan for 2023 performance were subject to the achievement of pre-established performance goals based on two equally-weighted performance criteria: (1) the compound annual growth rate (CAGR) in the Company’s book value per share, and (2) the CAGR in the Company’s closing stock price (total shareholder return), both over the five-year period from 2019 to 2023.

The Company believes that consistent increases in book value enhance the value of the Company and, over time, benefit shareholders through higher stock prices. For this reason, in 2023, the Company used growth in book value per share as a performance metric (which includes all underwriting, operating, and investing results) over a period of five years. The calculations of the CAGR in book value per share may be modified by the Compensation Committee to reflect transactions not in the ordinary course which may affect book value, including, but not limited to, share issuances or conversions, share repurchases, dividends, and capital or other transactions affecting book value.

Use of the metric of growth in total shareholder return is meant to acknowledge the participants’ role in formulating and implementing the long-term strategic direction and initiatives of the Company (including the allocation of capital) in consultation with the Board. As the Company has continued to expand and diversify its operations beyond underwriting and investing, the Compensation Committee recognizes that book value per share does not capture all of the economic value in the Company’s business, as a growing portion of the Company’s operations are not recorded at fair value or otherwise captured in book value. In particular, total shareholder return is meant to more appropriately capture the intrinsic value of the Company’s Markel Ventures operations, whose value arguably is not captured in the Company’s book value due to the fact that Markel Ventures companies are not represented on the Company’s balance sheet at “market” but instead at historic cost. Since 2005, the Company has acquired controlling interests in a diverse portfolio of businesses that operate in a variety of industries through its wholly owned subsidiary Markel Ventures, Inc. For the 2023 performance year, the CAGR in total shareholder return was calculated using the Company’s closing Common Stock price on December 31, 2018 and comparing it to the Company’s closing Common Stock price on December 31, 2023.

The five-year performance period underscores the Company’s long-term perspective and incents and rewards long-term, rather than short-term, decision making and behavior and provides balance between line of sight for actions currently being taken and a long-term perspective in managing the Company’s operations. In addition, using a longer-term measurement period does not encourage the taking of excessive or unnecessary risks in order to earn incentive compensation. The Compensation Committee believes using such a performance period aligns management’s interests with those of shareholders who are interested in long-term value creation.

The named executive officers have the potential to receive a majority of their total compensation in the form of incentive compensation. Moreover, if the Company achieves excellent performance over a multi-year period, a substantial majority of their total compensation would be in the form of incentive compensation.

All incentive-based compensation received by the named executive officers is subject to the Markel Group Compensation Recovery Policy. See “Compensation Recovery Policy” below.

32

Non-Equity Incentive Plan

The Non-Equity Incentive Plan was approved in May 2018 by the Board upon the recommendation of the Compensation Committee. The Non-Equity Incentive Plan is administered by the Compensation Committee. The Compensation Committee has the power and complete discretion to select eligible employees to receive awards thereunder and to determine the type of award and its terms and conditions in accordance with the Non-Equity Incentive Plan. Executive officers of the Company who the Compensation Committee determines have contributed or who can be expected to contribute significantly to the Company are eligible to receive awards under the Non-Equity Incentive Plan.

The performance criteria for 2023 for the named executive officers (other than Mr. Costanzo) were based on growth in book value per share and total shareholder return. The table below under “Performance-Based Non-Equity Awards and Equity Awards - Performance Criteria” sets forth the performance criteria grid approved by the Compensation Committee for determining the performance modifiers to be used to calculate the cash awards payable for 2023 performance based on various levels of growth in book value per share and total shareholder return and shows the potential value of cash awards, expressed as a percentage of target potential.

The performance modifiers and the target potential for each named executive officer for the 2023 performance year were as set forth in the award table below under “Payouts for 2023 Performance.” The named executive officers receive the appropriate payment at the end of the performance period if, as applicable, the performance criteria and other terms and conditions of the award are met. Awards are payable in cash.

The Compensation Committee reserves sole discretion in the case of growth in book value per share or total shareholder return under 6% in determining if cash awards are merited and, if so, in determining the performance modifier(s), subject to a cap of 20% of target potential, to be used to calculate such cash awards. The Compensation Committee also may approve, in its sole discretion, additional cash awards in the case of growth in book value per share or total shareholder return equal to or exceeding 17% or other supplemental cash awards, including awards made outside of the Non-Equity Incentive Plan, under other special circumstances.

See “Cash Incentive Compensation for Brian J. Costanzo” below for discussion of Mr. Costanzo’s cash incentive compensation.

See “Compensation for Teresa S. Gendron” below for discussion of Ms. Gendron’s cash incentive compensation.

Equity Incentive Plan

The 2016 Equity Incentive Plan was approved by shareholders in May 2016 at the Company’s 2016 Annual Meeting of Shareholders. The 2016 Equity Incentive Plan is administered by the Compensation Committee. The Compensation Committee has the power and complete discretion to select eligible employees who are executive officers to receive equity awards made thereunder and to determine the type of award and its terms and conditions in accordance with the 2016 Equity Incentive Plan. Executive officers of the Company who the Compensation Committee determines have contributed or who can be expected to contribute significantly to the Company are eligible to receive equity awards under the 2016 Equity Incentive Plan. The Compensation Committee has delegated to the Company’s CEO, Executive Vice President, and President, Markel Insurance, the authority to select eligible employees who are not executive officers to participate in the 2016 Equity Incentive Plan at set levels based on the employee’s position within the Company’s career framework for such employees. The Committee has further delegated authority to these persons to issue discretionary equity awards for newly-hired and current employees up to a certain dollar amount.

The performance criteria for 2023 for the named executive officers related to growth in book value per share and total shareholder return. The Compensation Committee approved performance-based equity awards, payable in RSUs, in February 2023 for the named executive officers, as well as other members of management of the Company and its subsidiaries. The table below under “Performance-Based Non-Equity Awards and Equity Awards - Performance Criteria” sets forth the performance criteria grid approved by the Compensation Committee for determining the performance modifiers to be used to calculate the equity awards payable for 2023 performance based on various levels of growth in book value per share and total shareholder return and shows the potential value of equity awards, expressed as a percentage of target potential.

The performance modifiers and the target potential for each named executive officer for the 2023 performance year were as set forth in the award table below under “Payouts for 2023 Performance.” Equity awards are payable in RSUs. Each RSU represents the right to receive one share of Common Stock. After an RSU is granted, the RSU is subject to a vesting schedule, usually cliff vesting after a three-year period. Paying a substantial portion of incentive compensation in RSUs has the advantage of both increasing the named executive officers’ equity ownership in the Company (which is aligned with the

33

Company’s emphasis on equity ownership by employees) and furnishing a retention incentive (i.e., the named executive officer must remain employed by the Company in order to be assured of vesting in the stock, subject to certain exceptions).

The Compensation Committee reserves sole discretion in the case of growth in book value per share or total shareholder return under 6% in determining if equity awards are merited and, if so, in determining the performance modifier(s), subject to a cap of 20% of target potential, to be used to calculate such equity awards. The Compensation Committee also may approve, in its sole discretion, additional equity awards in the case of growth in book value per share or total shareholder return equal to or exceeding 17% or other supplemental equity awards under other special circumstances.

Participating executive officers may elect to defer the issuance of Common Stock upon the vesting of RSU awards.

The 2016 Equity Incentive Plan does not allow for stock options or stock appreciation rights.

See “Compensation for Teresa S. Gendron” below for discussion of Ms. Gendron’s equity incentive compensation.

Payouts for 2023 Performance

The five-year CAGR in the Company’s book value per share from January 1, 2019 through December 31, 2023, taking into account adjustments for share repurchases and other equity account transactions, was 11%, and the five-year CAGR in the Company’s total shareholder return from January 1, 2019 through December 31, 2023, was 6%. Based on the performance grids set forth below under “Performance-Based Non-Equity Awards and Equity Awards - Performance Modifiers,” the performance modifier used to determine awards for the named executive officers under the Non-Equity Incentive Plan (other than Mr. Costanzo and Ms. Gendron) and the 2016 Equity Incentive Plan (other than Ms. Gendron) for 2023 performance was 75%, determined as follows: the performance modifier (expressed as a percentage of target potential) for each individual performance criteria (book value per share and total shareholder return) were added together to arrive at the total award performance modifier (expressed as a percentage of target potential):

Performance Criteria	5-Year CAGR	Performance Modifier Expressed as a Percentage of Target Potential
Book Value Per Share	11%	55%
Total Shareholder Return	6%	20%
	Total Performance Modifier:	75%

Cash awards and equity awards for the named executive officers under the Non-Equity Incentive Plan (other than Mr. Costanzo and Ms. Gendron) and the 2016 Equity Incentive Plan (other than Ms. Gendron), respectively, for the 2023 performance year were as follows, based on a 75% performance modifier:

	Target Potential Expressed as a Percentage of Base Salary*		Actual Award Expressed as a Percentage of Base Salary (calculation below)*
Name	Cash Award	Equity Award	Cash Payout	Equity Grant
Thomas S. Gayner	200%	500%	150%	375%
			(75% x 200%)	(75% x 500%)
Michael R. Heaton	150%	200%	113%	150%
			(75% x 150%)	(75% x 200%)
Jeremy A. Noble	150%	200%	113%	150%
			(75% x 150%)	(75% x 200%)
Richard R. Grinnan	100%	150%	75%	113%
			(75% x 100%)	(75% x 150%)
Brian J. Costanzo**	**	50%	**	38%
			**	(75% x 50%)
Teresa S. Gendron***	100%	150%	100%	150%
			(100% x 100%)	(100% x 150%)
* For the 2023 performance year, the Compensation Committee approved an increase in the target potential for cash awards: (i) for Mr. Gayner, from 150% to 200%; and (ii) for each of Messrs. Heaton and Noble, from 100% to 150%. The Compensation Committee also approved an increase in target potential for equity awards for the 2023 performance year for Mr. Gayner, from 400% to 500%.
** For Mr. Costanzo: (i) target potential and actual cash and equity awards are expressed as a percentage of eligible earnings, rather than a percentage of base salary; and (ii) target cash award and actual cash payout were based on a personal performance factor, a department goal modifier, and the Markel Modifier. See “Cash Incentive Compensation for Brian J. Costanzo” below for discussion of Mr. Costanzo’s cash incentive compensation.
*** See “Compensation for Teresa S. Gendron” below for discussion of Ms. Gendron’s incentive compensation for 2023.

Retention Awards

For recruitment and retention purposes, grants of RSUs have been made from time to time as circumstances warrant. Other than discretionary RSU awards discussed under “Discretionary Equity Awards” below, no retention awards were made in 2023 to any of the Company’s named executive officers.

Discretionary Equity Awards

On May 16, 2023, the Compensation Committee awarded to Messrs. Gayner, Heaton, Noble, Grinnan and Costanzo one-time discretionary equity awards, payable in RSUs, having a grant date value as identified in the following chart. The equity awards are time-based, with all of the RSUs vesting on May 16, 2026 if the recipient remains employed through that date (subject to the terms of the awards). The Compensation Committee approved these equity awards in conjunction with, and subject to, each executive (other than Mr. Costanzo) entering an amended and restated employment agreement that extended the term of each executive’s employment agreement with the Company through December 31, 2026, with automatic renewals for additional terms of one year thereafter unless either party gives 90 days’ notice of non-renewal (see “Employment Agreements” below).

	2023 Discretionary Equity Awards
Name	Grant Date Value	Vesting Date
Thomas S. Gayner	$1,449,607	May 16, 2026
Michael R. Heaton	$499,490	May 16, 2026
Jeremy A. Noble	$499,490	May 16, 2026
Richard R. Grinnan	$350,186	May 16, 2026
Brian J. Costanzo	$39,362	May 16, 2026

Cash Incentive Compensation for Brian J. Costanzo

Mr. Costanzo participated in the Markel Non-Underwriter Bonus Plan in 2023. The Non-Underwriter Bonus Plan is administered by management. The performance criteria for Mr. Costanzo was based on personal performance, department performance and the Markel Modifier, which is a payout percentage based on the Company’s combined ratio.

For the 2023 performance year, Mr. Costanzo had an initial cash award target of 75% of eligible earnings, which increased to 100% of eligible earnings upon his promotion to Chief Financial Officer of the Company’s Insurance operations. A personal performance factor of 125%, department modifier of 100%, and Markel Modifier of 75% were applied to Mr. Costanzo’s cash award which resulted in a cash payout at 94% of target. Mr. Costanzo’s cash award for 2023 was approved by the Compensation Committee.

Compensation for Teresa S. Gendron

Teresa S. Gendron became the Company’s Chief Financial Officer effective March 20, 2023. Ms. Gendron entered into an employment agreement and a sign-on bonus and reimbursement agreement with the Company, which were approved by the Compensation Committee. Under the agreements she was:

•Entitled to an annual base salary of not less than $650,000;

•Received a sign-on bonus of $395,000 in exchange for continuous full-time service to the Company for two years, with any unearned portions of the sign-on bonus repayable to the Company upon specified events;

•Eligible for an annual cash incentive bonus, subject to performance conditions approved by the Compensation Committee of the Company’s Board, with no proration and a guaranteed minimum payout at a target of 100% of base salary for 2023; and

•Eligible for an annual equity incentive award, subject to the approval of the Compensation Committee, with no proration and a guaranteed minimum payout at a minimum target grant date value of 150% of base salary for 2023.

The other terms of Ms. Gendron’s employment agreement were substantially the same as those for the Company’s other executive officers and are described herein under “Employment Agreements” and “Potential Payments upon Termination or Change in Control.”

Ms. Gendron also received a relocation package under which the Company agreed to cover qualifying expenses associated with her relocation to Richmond, Virginia and temporary travel and accommodation in Richmond, Virginia, from

35

her start date through the date of her relocation in September 2023. The Company reimbursed $45,980 in relocation expenses during 2023. Ms. Gendron must submit any additional relocation expenses for reimbursement, up to $750,000, by September 30, 2024.

On December 14, 2023, Ms. Gendron and the Company mutually agreed on a departure date of December 31, 2023, and she ceased to serve as Chief Financial Officer effective December 18, 2023. Ms. Gendron’s departure was not the result of any disagreement with the Company with respect to any matter relating to the financial controls, financial statements or any other operations, policies or practices of the Company.

Under Ms. Gendron’s employment agreement, provided she complies with the confidentiality, non-competition and non-solicitation covenants, and other applicable terms and conditions, therein: (i) the Company will continue to pay her annual base salary ($650,000) and provided the option to continue coverage under the Company’s group health plan for twenty four months (at an estimated cost of $13,738), which she declined, and (ii) she will be entitled to a lump sum payment equal to the amount of her target annual cash incentive bonus ($650,000), payable within 30 days following each of the first and second anniversaries of her termination date. In addition, her RSU award for 2023 became fully vested at the target amount ($975,000) as of the grant date. Ms. Gendron was entitled to retain the full amount of her sign-on bonus under the terms of her sign-on bonus and reimbursement agreement.

The Compensation Committee approved the terms of Ms. Gendron’s agreements and her separation.

Stock Ownership Guidelines

The Company places a strong emphasis on equity ownership by executive officers and other members of senior management. The Board has adopted stock ownership guidelines that require the CEO to acquire and maintain ownership of Common Stock with a value at least equal to five times base salary and other members of senior management to acquire and maintain ownership of Common Stock with a value at least equal to one to three times base salary, depending on position. RSUs subject to vesting requirements are counted as owned shares for purposes of the guidelines. Newly hired or newly promoted executives are expected to reach these minimum levels of ownership within five years. Our executive officers meet or exceed these guidelines, as applicable. See “Policy on Hedging and Pledging of Company Stock” above for information about the hedging and pledging policy applicable to the Company’s executive officers and directors.

Perquisites

The Company provides limited perquisites to its executive officers. In 2023, each of the named executive officers (other than Ms. Gendron) received less than $10,000 in perquisites and personal benefits. During 2023, Ms. Gendron was reimbursed $45,980 for relocation expenses. See “Compensation for Teresa S. Gendron” above for discussion of Ms. Gendron’s compensation.

Employment Agreements

The Company has entered into employment agreements with each of the named executive officers using a form of employment agreement for the Company’s executive officers approved by the Compensation Committee. On May 26, 2023, the Company entered amended and restated employment agreements with the named executive officers, other than Mr. Costanzo. Each amended and restated agreement updated the name of the Company from Markel Corporation to Markel Group Inc., extended the end of the initial term under the prior agreement for each executive from December 31, 2024 to December 31, 2026, and automatically renews for additional one-year terms unless the Company or the executive gives 90 days’ notice of non-renewal. In addition, each amended and restated agreement now includes a reference to the Company’s incentive-based compensation recoupment/clawback policy. Other than these changes, each amended and restated agreement has substantially the same terms and conditions as the prior agreement for each executive. An employment agreement was entered with Mr. Costanzo on December 18, 2023, upon his appointment as the Company’s Chief Financial Officer.

Each of the employment agreements provides assurances to the Company with regard to the availability of the named executive officer’s services, provides protection for the Company’s confidential information and trade secrets, and restricts the ability of the named executive officers to compete with the Company during their employment and after its termination. In return, the named executive officers are provided assurances with regard to salary, other compensation and benefits, as well as severance benefits if their employment is terminated by the Company other than for “cause.” For this purpose, “cause” includes neglect of duties; willful misconduct; conduct that may result in material injury to the reputation of the Company; active disloyalty; inability to maintain or obtain required regulatory approvals; or breach of obligations relating to confidential information, trade secrets or restrictions on competing with the Company.

In addition, each of the named executive officers is provided additional assurances following a change in control. In such a situation, they would receive enhanced severance benefits, but only if their employment were terminated without cause or if they chose to terminate their employment for “good reason.” See “Potential Payments Upon Termination or Change in Control” for a description of the benefits payable and for definitions of these terms. This additional “double

36

trigger” protection has been provided to these executives because they are considered more vulnerable in a change in control context due to their positions with the Company, their relative levels of equity ownership and the stage of their careers.

None of the employment agreements with the named executive officers include provisions for tax gross-ups, in respect of the “parachute payment” tax imposed by Section 280G of the Code or otherwise.

Tax and Accounting Treatment

Section 162(m) of the Code imposes a $1,000,000 limit on the amount of compensation that will be deductible for U.S. tax purposes by the Company with respect to the Chief Executive Officer, the Chief Financial Officer, and the three other most highly compensated executive officers (each a Covered Employee). In addition, once an individual becomes a Covered Employee for any taxable year beginning after December 31, 2016, that individual will remain a Covered Employee for all future years. The Tax Cuts and Jobs Act eliminated the exception for performance-based compensation to the Section 162(m) deduction limit, effective for taxable years beginning after December 31, 2017. As a result, compensation paid to a Covered Employee in excess of $1,000,000 will not be deductible unless it qualifies for transition relief under the Tax Cuts and Jobs Act.

Compensation expense with respect to RSUs is fixed for accounting purposes based on the fair value of the award at the grant date, i.e., the date on which the Compensation Committee determines the number of RSUs to be awarded. The compensation expense generally is recognized over the period ending when the awards vest.

As required by NYSE listing standards, the Board adopted the Markel Group Compensation Recovery Policy, which became effective October 2, 2023. Under the policy, the Company must recover reasonably promptly the amount of erroneously awarded incentive-based compensation received by covered officers, including the named executive officers, if the Company is required to prepare an accounting restatement due to the Company’s material noncompliance with any financial reporting requirement under U.S. federal securities laws, including any required accounting restatement to correct an error in previously issued financial statements that is material to the previously issued financial statements, or that would result in a material misstatement if the error were corrected in the current period or left uncorrected in the current period. A copy of the Compensation Recovery Policy has been filed as Exhibit 97 to the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2023.

Say on Pay and Say on Frequency Votes

Currently shareholders have the opportunity every year to cast a non-binding advisory vote to approve executive compensation (Say on Pay). At the 2023 Annual Meeting, more than 98% of the votes cast approved the Company’s executive compensation program. Shareholders also are asked at least once every six years to vote, on a non-binding advisory basis, on how often a Say on Pay vote should be held (Say on Frequency). At the 2023 Annual Meeting of Shareholders, more than 97% of the votes cast were in favor of holding future Say on Pay votes every year. The next Say on Pay vote will be held at the 2024 Annual Meeting. The next Say on Frequency vote is expected to occur in 2029.

a	For 2023, non-equity incentive plan awards for the named executive officers (other than Mr. Costanzo) were subject to a cap of 200% of target potential, which is the amount shown under the “Maximum” column. The Compensation Committee reserves the right to reduce the maximum amount payable in its discretion. In addition, the Compensation Committee reserves sole discretion in the case of growth in book value per share or total shareholder return under 6% in determining if cash awards are merited and, if so, in determining the performance modifier(s), subject to a cap of 20% of target potential, to be used to calculate such cash awards. The Compensation Committee also may approve, in its sole discretion, additional cash awards in the case of growth in book value per share or total shareholder return equal to or exceeding 17% or other supplemental cash awards, including awards made outside of the Non-Equity Incentive Plan, under other special circumstances.
b	The number of RSUs awarded is determined by dividing the dollar amount by the fair market value of Common Stock on the date that the Compensation Committee certifies that the performance goals, if any, have been met, or on the date of such award if not subject to any performance goals. For 2023, awards under the 2016 Equity Incentive Plan (other than the May 16, 2023 discretionary, time-based RSU awards) for the named executive officers were subject to a cap of 200% of target potential, which is the amount shown under the “Maximum” column. The Compensation Committee reserves the right to reduce the maximum amount payable in its discretion. In addition, the Compensation Committee reserves sole discretion in the case of growth in book value per share or total shareholder return under 6% in determining if equity awards are merited and, if so, in determining the performance modifier(s), subject to a cap of 20% of target potential, to be used to calculate such equity awards. The Compensation Committee also may approve, in its sole discretion, additional equity awards in the case of growth in book value per share or total shareholder return equal to or exceeding 17% or other supplemental equity awards under other special circumstances. See “Discretionary Equity Awards” above for a description of the May 16, 2023 discretionary, time-based RSU awards.
c	Mr. Costanzo’s non-equity incentive plan award threshold payout assumes a Markel Modifier of 70%, and his maximum payout assumes a Markel Modifier of 150% and a personal performance modifier of 130%. Mr. Costanzo’s non-equity incentive plan award and equity incentive plan award were based on eligible earnings for 2023, rather than base salary. See “Cash Incentive Compensation for Brian J. Costanzo” for a discussion of Mr. Costanzo’s cash incentive compensation.
d	Pursuant to the terms of her employment agreement, Ms. Gendron’s awards were guaranteed minimum payouts at target for 2023. See “Compensation for Teresa S. Gendron” for discussion of Ms. Gendron’s compensation.
e	Ms. Gendron’s RSU award for 2023 became fully vested as of the grant date.

Discussion

When targets are set for performance-based Non-Equity Incentive Plan and 2016 Equity Incentive Plan awards, potential awards are expressed as a percentage of target potential. In the case of growth in book value per share or total shareholder return under 6%, the Compensation Committee reserves sole discretion in determining if cash or equity awards are merited and if so, in determining the performance modifier(s), subject to a cap of 20% of target potential, to be used to calculate such awards. The Compensation Committee also may approve, in its sole discretion, additional cash or equity awards in the case of growth in book value per share or total shareholder return equal to or exceeding 17% or other supplemental cash or equity awards, including cash awards made outside of the Non-Equity Incentive Plan, under other special circumstances.

The table above shows all grants of cash and equity awards made under the Non-Equity Incentive Plan (other than for Mr. Costanzo) and the 2016 Equity Incentive Plan, respectively, for 2023 performance.

•For the equity awards with a grant date of May 16, 2023, the “Grant Date Fair Value of Stock Awards” column shows the fair value of the discretionary, time-based RSU awards actually made on that date. See “Discretionary Equity Awards” above for a description of these awards.

39

•For the equity awards with a grant date of February 20, 2024, (i) the “All Other Stock Awards” column represents the actual payout made in 2024 for 2023 performance and (ii) the “Grant Date Fair Value of Stock Awards” column shows the fair value, for financial reporting purposes, of the awards actually made on that date for 2023.

•Amounts shown in the “Non-Equity Incentive Plan Awards” and “Equity Incentive Plan Awards” columns (other than the awards made May 16,2023) for all named executive officers reflect potential payouts for 2023 performance to each named executive officer at threshold, target and maximum performance levels. To compare these potential payouts with amounts actually paid, see the discussion below under “Performance-Based Non-Equity Awards and Equity Awards.”

Performance-Based Non-Equity Awards and Equity Awards

For 2023, all named executive officers were eligible to receive:

•Performance-based cash awards under the Company’s Non-Equity Incentive Plan (other than for Mr. Costanzo), expressed as a percentage of target potential; and

•Performance-based equity awards, payable in RSUs, approved by the Compensation Committee, expressed as a percentage of target potential. Each RSU represents the right to receive one share of Common Stock.

Performance Criteria

For all named executive officers, potential cash awards (other than for Mr. Costanzo and Ms. Gendron) and potential equity awards (other than for Ms. Gendron) were based on a 50/50 weighting of the CAGR of the two performance criteria, book value per share of Common Stock and total shareholder return, as set forth in the grid below.

5-Year CAGR	Book Value Per Share as a % of Target Potential	Total Shareholder Return as a % of Target Potential	Total Award as a % of Target Potential
Under 6%*	0 - 20%	0 - 20%	0 - 40%
6%	20%	20%	40%
7%	30%	30%	60%

*	In the case of performance in this range, the Compensation Committee, in its sole discretion, will determine if an award is merited based upon relevant facts and circumstances.
**	In the case of performance in this range, the Compensation Committee, in its sole discretion, will determine if an additional award is merited based upon relevant facts and circumstances.

Performance Modifiers

As noted under “Payouts for 2023 Performance” above: (a) the five-year CAGR in book value per share from January 1, 2019 through December 31, 2023, taking into account adjustments for share repurchases and other equity account transactions, was 11%, and the five-year CAGR in total shareholder return from January 1, 2019 through December 31, 2023, was 6%; and (b) based on the performance grids set forth above, the performance modifiers used to determine awards under the Non-Equity Incentive Plan and the 2016 Equity Incentive Plan for 2023 performance were as follows for all of the named executive officers (other than as noted below under “Awards” for Mr. Costanzo and Ms. Gendron):

Performance Criteria	5-Year CAGR	Performance Modifier Expressed as a Percentage of Target Potential
Book Value Per Share	11%	55%
Total Shareholder Return	6%	20%
	Total Performance Modifier:	75%

Awards

After taking into account the performance criteria and corresponding performance modifiers noted above, cash awards and equity awards for the named executive officers (other than as noted below for Mr. Costanzo and Ms. Gendron) under the Non-Equity Incentive Plan and the 2016 Equity Compensation Plan, respectively, for the 2023 performance year were as follows, based on a 75% performance modifier:

	Target Potential Expressed as a Percentage of Base Salary*		Actual Award Expressed as a Percentage of Base Salary (calculation below)*
Name	Cash Award	Equity Award	Cash Payout	Equity Grant
Thomas S. Gayner	200%	500%	150%	375%

* For the 2023 performance year, the Compensation Committee approved an increase in the target potential for cash awards: (i) for Mr. Gayner, from 150% to 200%; and (ii) for each of Messrs. Heaton and Noble, from 100% to 150%. The Compensation Committee also approved an increase in target potential for equity awards for the 2023 performance year for Mr. Gayner, from 400% to 500%.
** For Mr. Costanzo: (i) target potential and actual cash and equity awards are expressed as a percentage of eligible earnings for 2023, rather than a percentage of base salary; and (ii) target cash award and actual cash payout were based on a personal performance factor, a department modifier, and the Markel Modifier. See “Cash Incentive Compensation for Brian J. Costanzo” above for discussion of Mr. Costanzo’s cash incentive compensation.
*** Pursuant to the terms of her employment agreement, amounts for actual cash and equity awards represent guaranteed minimum payouts at target. See “Compensation for Teresa S. Gendron” for discussion of Ms. Gendron’s compensation.

a	See table included under “Discussion” below for the applicable vesting schedules.
b	Values are based on the closing price of shares of Common Stock on December 31, 2023 ($1,419.90 per share).
c	Does not include 1,112 RSUs that have not been settled in shares to Mr. Gayner at December 31, 2023, but which pursuant to a retention award made in May 2010 have vested. These RSUs will be settled in shares following termination of employment. Violation of non-competition agreements contained in the award agreement may result in cancellation of the award, even after vesting.

Discussion

The stock awards reflected in the table above are RSUs granted under the Company’s 2016 Equity Incentive Plan, which, as of December 31, 2023, were scheduled to vest as follows:

	RSUs Vesting
Name	February 2024	December 2024	December 2025	May 2026
Thomas S. Gayner	—	1,874	1,558	1,068
Michael R. Heaton	92	342	482	368
Jeremy A. Noble	—	535	482	368
Richard R. Grinnan	—	297	306	258
Brian J. Costanzo	—	69	54	29
Teresa S. Gendron	—	—	—	—

In general, unvested RSUs held by an executive officer will be forfeited upon a separation from service before the vesting date. However, early vesting, in whole or in part, may occur upon an executive’s separation from service under certain circumstances, including: due to death, disability, military service or involuntary termination without cause; the executive having satisfied certain age and service requirements at the time of separation; following a change in control; or if the Compensation Committee determines the executive had an approved termination of employment. The shares generally will be issued on the date on which the separation occurs or such other date designated in the relevant award agreement (or as soon as administratively practicable thereafter). See “Compensation for Teresa S. Gendron” for discussion of Ms. Gendron’s compensation in connection with her separation from the Company.

However, in most cases, an executive’s RSU awards, and any payments received thereunder, may be subject to cancellation and/or repayment, as applicable, if the Compensation Committee determines that, during the executive’s employment or within a specified period thereafter: (i) the executive has violated certain non-competition or non-solicitation obligations; (ii) the executive’s employment has been terminated for cause; (iii) the executive has disclosed the terms of the awards in violation of confidentiality obligations; or (iv) the executive has engaged in conduct detrimental to the interests of the Company. In addition, all incentive-based compensation received by the named executive officers is subject to the Markel Group Compensation Recovery Policy (see “Compensation Recovery Policy” above).

Holders of RSUs are not entitled to receive dividends, if any, before vesting and issuance of the shares underlying the RSUs.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

In May 2023, the Company entered into amended and restated employment agreements with each of the named executive officers (other than Mr. Costanzo).

The amended and restated employment agreements extend the end of the initial terms from December 31, 2024 to December 31, 2026 and are automatically renewed for additional terms of one year unless either party gives 90 days’ notice of non-renewal. If the Company chooses not to renew, the Company will be deemed to have terminated the executive’s employment without cause. An employment agreement was entered with Mr. Costanzo on December 18, 2023, upon his appointment as the Company’s Chief Financial Officer.

Under the employment agreements, each named executive officer will:

•receive annual base salary, subject to annual review;

•be eligible for an annual cash incentive bonus, subject to performance conditions approved by the Compensation Committee, having a target potential equal to a specified percentage of base salary;

•be eligible for an annual equity incentive award, subject to the approval of the Compensation Committee, having a target potential equal to a specified percentage of base salary and subject to performance conditions approved by the Compensation Committee; and

•be entitled to participate in the employee benefit plans and programs, including annual paid time off, generally available to other similarly situated senior executives of the Company.

The employment agreements require each executive to preserve the confidentiality of the Company's confidential information, and, during the term of the agreement and for twelve months following the termination of employment, subject them to non-competition and non-solicitation restrictions.

The employment agreements also provide that:

•upon death or disability, the Company will continue to pay base salary for twelve months, and all outstanding granted equity awards will become fully vested, with performance equity awards vesting at the target level;

•if employment is terminated by the Company for cause, then the Company’s obligations under the agreement will terminate;

•if the executive resigns or voluntarily leaves, except under the circumstances described below, the Company’s obligations under the agreement will terminate, subject to the terms of any applicable RSU or other equity award agreement; and

•if employment is terminated by the Company without cause, the executive voluntarily resigns with good reason following a change in control, or the executive otherwise voluntarily resigns by virtue of a material breach by the Company, then, provided the executive complies with the confidentiality, non-competition and non-solicitation covenants in, and other applicable terms and conditions under, the agreement, (i) the Company will continue to pay his or her base salary commencing within 60 days after termination (or beginning six months after termination if certain provisions of Section 409A of the Internal Revenue Code of 1986, as amended, apply) and provide continued coverage under the Company’s group health plan for twenty-four months for Messrs. Gayner, Heaton and Noble, and for twelve months for Messrs. Grinnan and Costanzo, (ii) the executive will be entitled to a lump sum payment equal to the amount of his or her target annual cash incentive bonus, payable within 30 days following the first and second anniversaries of the termination date for Messrs. Gayner, Heaton and Noble, and following the first anniversary of the termination date for Messrs. Grinnan and Costanzo, and (iii) all outstanding granted equity awards held by the executive will become fully vested as of the termination date, with performance equity awards vesting at the target level.

For these purposes:

•“Cause” includes neglect of duties; willful misconduct; conduct that may result in material injury to the reputation of the Company; active disloyalty; inability to maintain or obtain required regulatory approvals; or breach of obligations relating to confidential information, trade secrets or restrictions on competing with the Company.

•“Good reason” means a material decrease in base salary; a material reduction in duties or responsibilities; a material breach of the agreement by the Company; or a change by more than 50 miles in the location from which the executive is expected to perform his or her duties.

•“Change in control” means generally the liquidation or dissolution of the Company; the acquisition of 20% or more of the Company’s outstanding shares; a business combination involving the Company; or a change in a majority of the incumbent Board of the Company, in each case unless the owners of 50% or more of the Company’s outstanding voting securities before the transaction remain the owners of 50% or more of the outstanding voting securities of the Company or other resulting entity following a transaction.

Cash Payments and Benefits

The estimated cash payments and benefits that would be provided upon termination under the various scenarios set forth above are quantified in the following table, assuming termination of employment took place on December 31, 2023. Upon a breach of applicable covenants in each employment agreement, including regarding competition or confidential information, the Company would not be obligated to continue making payments.

Equity Awards

In addition to the cash payments and benefits described under “Cash Payments and Benefits” above, under each executive’s employment agreement, if, within twelve months following a change in control, employment is terminated involuntarily without cause or the named executive officer voluntarily terminated employment for good reason:

•All outstanding, unvested equity awards held by the named executive officer would become fully vested. As of December 31, 2023, Messrs. Gayner, Heaton, Noble, Grinnan and Costanzo had received RSUs that had not yet vested. See “Outstanding Equity Awards at Fiscal Year-End” above for a summary of outstanding RSUs, and the market value of those RSUs, at December 31, 2023; and

•All performance-based equity awards for such executive for which the performance period had not yet been fully completed would be deemed fully vested at 100% target potential. At December 31, 2023, that would have resulted in the issuance of additional shares of Common Stock worth the amounts set forth in the grid below.

Name	Value of Common Stock
Thomas S. Gayner	$5,250,000
Michael R. Heaton	$1,550,000
Jeremy A. Noble	$1,550,000
Richard R. Grinnan	$900,000
Brian J. Costanzo*	$500,000
* Amounts have been calculated based on potential equity payouts in effect on January 1, 2024.

PAY RATIO

As required and set forth by Section 953(b) of the Dodd-Frank Act, and Item 402(u) of Regulation S-K (the Pay Ratio Rule), we are providing the following information about the relationship of the annual total compensation of our median employee to the annual total compensation of our PEO during 2023.

For 2023, our last completed fiscal year:

•the annual total compensation of our median employee was $55,103; and

•the annual total compensation of our PEO was $8,091,063.

Based on this information, for 2023, the ratio of the annual total compensation of our PEO to the annual total compensation of our median employee was 146.8 to 1.

To determine the annual total compensation of our median employee and our PEO, we used the following methodology and material assumptions, adjustments and estimates:

1.We determined that, as of October 1, 2023, our employee population, excluding our PEO, consisted of approximately 21,337 individuals working at our consolidated subsidiaries as of such date, of which approximately 18,522 were U.S. employees and approximately 2,815 were non-U.S. employees. This population consisted of full-time, part-time, temporary and seasonal employees employed on that date.

2.We selected October 1, 2023, which was the earliest date in 2023 permitted under the Pay Ratio Rule, as the determination date for identifying the median employee to allow sufficient time to identify the median employee given the global scope of our operations. This approach is consistent with the approach we have taken in prior years.

3.Our employee population for determining the median employee, after taking into consideration certain adjustments allowed by the Pay Ratio Rule, consisted of approximately 20,682 individuals in the United States, United Kingdom, Dominican Republic and Canada. As permitted under the Pay Ratio Rule, we excluded 655 non-U.S. employees from the determination of the median employee to reduce the number of jurisdictions and separate payrolls, and thus the significant time and effort, involved in identifying the median employee. The number and jurisdictions of the excluded non-U.S. employees were as follows: 215 in the Netherlands, 98 in Bermuda, 84 in China, 77 in Germany, 56 in Spain, 34 in Singapore, 19 in India, 15 in France, 15 in Ireland, 12 in the United Arab Emirates, 8 in Mexico, 7 in Hong Kong, 6 in Vietnam, 2 in Australia, 2 in Lebanon, 2 in Malaysia, 2 in the Philippines and 1 in Brazil.

4.To identify the median employee from our employee population as of October 1, 2023, we consistently compared the amount of compensation for all our employees (excluding our PEO) included in the calculation as reflected in our payroll records for the period from January 1 to September 30, 2023 using the equivalent of Medicare taxable wages as reported in IRS Form W-2. For our employees who were paid in a currency other than U.S. dollars, these amounts were converted into U.S. dollars at the applicable exchange rates at October 1, 2023.

5.For purposes of determining annual total compensation for 2023 for our median employee and our PEO, we used the same method used to determine the respective amounts reported for our PEO in the “Total” column of our 2023 Summary Compensation Table included in this Proxy Statement, plus compensation under non-discriminatory benefit plans. For our PEO, this included $22,772 in compensation under non-discriminatory benefit plans not reflected in the Summary Compensation Table.

Each Performance Grant shall contain the Performance Goals for the award, including the performance measures, the target and maximum amounts payable and such other terms and conditions of the Performance Grant. The terms of a Performance Grant may be set forth in an annual or long-term bonus or incentive plan of Markel or a Subsidiary.

(c) Unless otherwise provided in the Performance Grant, the employee must remain continuously employed with Markel or a Subsidiary through the last day of the applicable performance period in order to be eligible to receive payment under the award; provided, however, the Committee may provide for accelerated vesting or payment of a Performance Grant upon such events as the Committee deems appropriate, including without limitation a Participant’s death, Disability, Retirement or Early Retirement or the occurrence of a Change in Control.

The performance period with respect to any such award shall be at least twelve consecutive months, provided the Committee may provide for accelerated vesting upon a Participant’s death, Disability,

Retirement or Early Retirement or the occurrence of a Change in Control. The Committee will make all determinations regarding the satisfaction of any Performance Goals for such an award.

(b) “Director stock” or “director units” (or other similar types of awards), which are shares or units of Company Stock granted to Outside Directors only, which are vested immediately on grant, but which may not be transferred by the Participant (or, in the case of units, paid to the Participant) until the Participant’s separation from service from the Board (except as necessary to satisfy the Outside Director’s tax liability in connection with the grant).

(c) Notwithstanding the foregoing, “Other Stock Awards” shall not include stock options or stock appreciation rights, which are not authorized for issuance under the Plan.

9. Dividend Equivalents. The Committee (with respect to employees), or the Outside Directors of the Board (with respect to Outside Directors), may provide that any Incentive Awards under the Plan earn dividends or dividend equivalents. Such dividends or dividend equivalents shall be credited to a Participant’s account, either in cash without interest or as reinvestment in additional shares or share equivalents. Any crediting of dividends or dividend equivalents shall be subject to the same restrictions and conditions as the underlying award. Except as provided by the foregoing, no Participant or Beneficiary shall have any rights as a shareholder of Markel with respect to an Incentive Award, including without limitation any rights to vote shares of Company Stock or to receive dividends or other distributions with respect thereto, unless and until he becomes the holder of record of shares of Company Stock under such award.

10. Tax Withholding. Whenever payment under an Incentive Award is made in cash, the Employer will withhold an amount sufficient to satisfy any Applicable Withholding Taxes. Each Participant who is an employee shall agree as a condition of receiving an Incentive Award payable in the form of Company Stock, to pay to the Employer, or make arrangements satisfactory to the Employer regarding the payment to the Employer of, Applicable Withholding Taxes. To satisfy Applicable Withholding Taxes and under procedures established by the Committee or its delegate, a Participant may elect to (i) make a cash payment or authorize additional withholding from cash compensation, or (ii) have Markel retain that number of shares of Company Stock (valued at their Fair Market Value) that would satisfy all or a specified portion of the Applicable Withholding Taxes.

11. Transferability of Incentive Awards. Incentive Awards shall not be transferable by a Participant, except in accordance with the Participant’s will or the laws of descent and distribution or as otherwise expressly provided in the Incentive Award. If a Participant dies, any outstanding Incentive Awards that are otherwise payable to the Participant shall be paid to the Participant’s Beneficiary or, if no Beneficiary is designated, to the personal representative of the Participant’s estate or to the person to whom rights under the Incentive Award shall have passed by will or the laws of descent and distribution.

The Committee (with respect to employees) and the Outside Directors of the Board (with respect to Outside Directors) may permit Participants to elect to defer the issuance of Company Stock or the settlement of awards in cash under the Plan under such rules, procedures, or programs as it may establish, in accordance with Section 409A of the Code and any other applicable laws, rules or regulations.

13. Effective Date of the Plan. The effective date of the Plan is ________, 2024. The Plan shall be submitted to the shareholders of Markel for approval.

14. Termination, Amendment. If not sooner terminated by the Board, this Plan shall terminate at the close of business on December 31, 2034. No Incentive Awards shall be made under the Plan after its termination. The Board may amend or terminate the Plan as it shall deem advisable; provided that no change shall be made that increases the total number of shares of Company Stock reserved for issuance under Incentive Awards granted under the Plan (except under Section 15), expands the types of awards under the Plan, materially expands the eligible participants or any other amendment requiring approval of Markel’s shareholders under New York Stock Exchange listing standards or applicable law, unless such change is authorized by the shareholders of Markel.
