MARKEL GROUP INC. AND SUBSIDIARIES

NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

1. Summary of Significant Accounting Policies

Markel Group Inc. (Markel Group) is a holding company comprised of a diverse group of companies and investments with specialty insurance at its core. Through its wholly owned subsidiary, Markel Ventures, Inc. (Markel Ventures), Markel Group owns controlling interests in businesses that operate in a variety of industries. See note 2 for details regarding reportable segments.

a) Basis of Presentation. The consolidated balance sheet as of March 31, 2024 and the related consolidated statements of income and comprehensive income and changes in equity for the three months ended March 31, 2024 and 2023, and the condensed consolidated statements of cash flows for the three months ended March 31, 2024 and 2023 are unaudited. In the opinion of management, all adjustments necessary for fair presentation of such consolidated financial statements have been included. Such adjustments consist only of normal, recurring items. Interim results are not necessarily indicative of results of operations for the entire year. The consolidated balance sheet as of December 31, 2023 was derived from Markel Group's audited annual consolidated financial statements.

The accompanying consolidated financial statements have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) and include the accounts of Markel Group and its consolidated subsidiaries, as well as variable interest entities (VIEs) that meet the requirements for consolidation (the Company). All significant intercompany balances and transactions have been eliminated in consolidation. The Company consolidates the results of its Markel Ventures subsidiaries on a one-month lag, with the exception of significant transactions or events that occur during the intervening period. Certain prior period amounts have been reclassified to conform to the current period presentation.

The preparation of financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of contingent assets and liabilities. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

The consolidated financial statements and notes are presented as permitted by Form 10-Q and do not contain certain information included in the Company's annual consolidated financial statements and notes. For a more complete description of the Company's business and accounting policies, readers are urged to review the Company's 2023 Annual Report on Form 10-K.

b) Recent Accounting Pronouncements

Accounting Standards Not Yet Adopted

In November 2023, the Financial Accounting Standards Board (FASB) issued Accounting Standards Update (ASU) No. 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The standard requires public companies to, among other things: (1) disclose, on an annual and interim basis, significant segment expenses that are regularly provided to the chief operating decision maker and included within each reported measure of segment profit or loss; (2) disclose, on an annual and interim basis, an amount for other segment expenses that are not separately disclosed as significant segment expenses and a description of its composition; (3) provide all annual disclosures about a reportable segment's profit or loss and assets currently required by Topic 280 in interim periods; and (4) disclose the title and position of the chief operating decision maker and an explanation of how the chief operating decision maker uses the reported measures of segment profit or loss in assessing segment performance and deciding how to allocate resources. ASU No. 2023-07 becomes effective for the Company in the fourth quarter of 2024 and will be applied using a retrospective approach that requires recasting of all prior periods presented. The standard only impacts required disclosures and will not impact the Company's financial position, results of operations or cash flows.

In December 2023, the FASB issued ASU No. 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures. The standard requires public companies, on an annual basis, to provide enhanced rate reconciliation disclosures, including disclosure of specific categories and additional information for reconciling items that meet a quantitative threshold. The standard also requires public companies to, among other things, disaggregate income taxes paid by federal, state and foreign taxes. ASU No. 2023-09 becomes effective for the Company's 2025 Annual Report on Form 10-K. The standard only impacts required disclosures and will not impact the Company's financial position, results of operations or cash flows.

2. Segment Reporting Disclosures

The Company has four reportable segments: Insurance, Reinsurance, Investing and Markel Ventures.

The chief operating decision maker reviews the Company's ongoing underwriting operations on a global basis in the following two segments: Insurance and Reinsurance. The Insurance segment includes all direct business and facultative reinsurance placements written on a risk-bearing basis within the Company's underwriting operations. The Reinsurance segment includes all treaty reinsurance written on a risk-bearing basis within the Company's underwriting operations.

The Company's other insurance operations primarily consist of the results of the Company's program services and other fronting business and insurance-linked securities operations. Other insurance operations also include results for lines of business discontinued prior to, or in conjunction with, acquisitions, including development on asbestos and environmental loss reserves and results attributable to the run-off of life and annuity reinsurance business, which are monitored separately from the Company's ongoing underwriting operations. For purposes of segment reporting, none of these other insurance operations are considered to be reportable segments.

The Company's Investing segment includes all investing activities related to the Company's insurance operations, as well as investing activities at Markel Group. Invested assets managed through our Investing segment include our portfolio of publicly traded fixed maturity and equity securities, as well as cash and short-term investments.

The Markel Ventures segment primarily consists of controlling interests in a diverse portfolio of businesses that operate in various industries. The Company's chief operating decision maker reviews and assesses Markel Ventures' performance in the aggregate, as a single operating segment.

Segment profit for all of the Company's segments is measured by operating income. Segment operating income excludes amortization of intangible assets arising from purchase accounting for acquisitions, which the chief operating decision maker does not consider in assessing the financial performance of, or allocating resources to, operating segments. Amortization of acquired intangible assets is considered a corporate expense because it is not a cost of operating the underlying businesses. For our Insurance and Reinsurance segments, segment operating income is typically consistent with underwriting profit, which the property and casualty insurance industry commonly defines as earned premiums net of losses and loss adjustment expenses and underwriting, acquisition and insurance expenses. Segment operating income for these two segments may also include other revenues and expenses that are not captured in underwriting profit.

Prior to 2024, the segment profitability metric for the Markel Ventures segment included amortization of acquired intangible assets. The new metric, as previously described, better aligns with how the chief operating decision maker reviews and assesses the performance of the Markel Ventures segment. Prior periods have been recast to conform to the current presentation. Management continues to evaluate the Company's segments as its business evolves and may further refine its segments and segment profitability metric.

For management reporting purposes, the Company allocates assets to its underwriting operations and to its Investing and Markel Ventures segments and certain of its other insurance operations, including its program services and other fronting business and insurance-linked securities business. Underwriting assets include assets attributed to the Company's Insurance and Reinsurance segments, discontinued underwriting lines of business, as well as assets that are not specifically allocated to the Company's other insurance operations. Generally, the Company manages its underwriting assets in the aggregate and therefore does not allocate assets to individual underwriting segments.

At December 31, 2023, the Company held 1,386 available-for-sale securities in an unrealized loss position with a total estimated fair value of $10.0 billion and gross unrealized losses of $661.3 million. Of these 1,386 securities, 1,131 securities had been in a continuous unrealized loss position for one year or longer and had a total estimated fair value of $8.5 billion and gross unrealized losses of $650.5 million.

The Company completes a detailed analysis each quarter to assess whether the decline in the fair value of any investment below its cost basis is the result of a credit loss. All available-for-sale securities with unrealized losses are reviewed. The Company considers many factors in completing its quarterly review of securities with unrealized losses for credit-related impairment to determine whether a credit loss exists, including the extent to which fair value is below cost, the implied yield to maturity, rating downgrades of the security and whether or not the issuer has failed to make scheduled principal or interest payments. The Company also takes into consideration information about the financial condition of the issuer and industry factors that could negatively impact the issuer.

If the decline in fair value of an available-for-sale security below its amortized cost is considered to be the result of a credit loss, the Company compares the estimated present value of the cash flows expected to be collected to the amortized cost of the security. The extent to which the estimated present value of the cash flows expected to be collected is less than the amortized cost of the security represents the credit loss, which is recorded as an allowance and recognized in net income. The allowance is limited to the difference between the fair value and the amortized cost of the security. Any remaining decline in fair value represents the non-credit portion of the impairment, which is recognized in other comprehensive income. The Company did not have an allowance for credit losses for any available-for-sale securities as of March 31, 2024 or December 31, 2023.

Quarterly, the Company also considers whether it intends to sell an available-for-sale security or if it is more likely than not that it will be required to sell a security before recovery of its amortized cost. In these instances, a decline in fair value is recognized in net income based on the fair value of the security at the time of assessment, resulting in a new cost basis for the security.

4. Fair Value Measurements

FASB ASC 820, Fair Value Measurements and Disclosures, establishes a three-level hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The fair value hierarchy gives the highest priority to quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). If the inputs used to measure the assets or liabilities fall within different levels of the hierarchy, the classification is based on the lowest level input that is significant to the fair value measurement of the asset or liability.

Classification of assets and liabilities within the hierarchy considers the markets in which the assets and liabilities are traded and the reliability and transparency of the assumptions used to determine fair value. The hierarchy requires the use of observable market data when available. The levels of the hierarchy are defined as follows:

•Level 1 – Inputs to the valuation methodology are quoted prices (unadjusted) for identical assets or liabilities traded in active markets.

•Level 2 – Inputs to the valuation methodology include quoted prices for similar assets or liabilities in active markets, quoted prices for identical or similar assets or liabilities in markets that are not active, inputs other than quoted prices that are observable for the asset or liability and market-corroborated inputs.

•Level 3 – Inputs to the valuation methodology are unobservable for the asset or liability and are significant to the fair value measurement.

In accordance with ASC 820, the Company determines fair value based on the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. In determining fair value, the Company uses various methods, including the market, income and cost approaches. The Company uses valuation techniques that maximize the use of observable inputs and minimize the use of unobservable inputs. The following section describes the valuation methodologies used by the Company to measure assets and liabilities at fair value, including an indication of the level within the fair value hierarchy in which each asset or liability is generally classified.

13

Available-for-sale investments and equity securities. Available-for-sale investments and equity securities are recorded at fair value on a recurring basis. Available-for-sale investments include fixed maturity securities and short-term investments. Fair value is determined by the Company after considering various sources of information, including information provided by a third-party pricing service. The pricing service provides prices for substantially all of the Company's fixed maturity securities and equity securities. In determining fair value, the Company generally does not adjust the prices obtained from the pricing service. The Company obtains an understanding of the pricing service's valuation methodologies and related inputs, which include, but are not limited to, reported trades, benchmark yields, issuer spreads, bids, offers, duration, credit ratings, estimated cash flows and prepayment speeds. The Company validates prices provided by the pricing service by reviewing prices from other pricing sources and analyzing pricing data in certain instances.

The Company has evaluated the various types of securities in its investment portfolio to determine an appropriate fair value hierarchy level based upon trading activity and the observability of market inputs. Level 1 investments include those traded on an active exchange, such as the New York Stock Exchange. Level 2 investments include U.S. Treasury securities, U.S. government-sponsored enterprises, municipal bonds, foreign government bonds, commercial mortgage-backed securities, residential mortgage-backed securities and corporate debt securities. Level 3 investments include the Company's investments in insurance-linked securities funds that are in run-off, which are not traded on an active exchange and are valued using unobservable inputs.

Fair value for available-for-sale investments and equity securities is measured based upon quoted prices in active markets, if available. Due to variations in trading volumes and the lack of quoted market prices, fixed maturity securities are classified as Level 2 investments. The fair value of fixed maturity securities is normally derived through recent reported trades for identical or similar securities, making adjustments through the reporting date based upon available market observable data previously described. If there are no recent reported trades, the fair value of fixed maturity securities may be derived through the use of matrix pricing or model processes, where future cash flow expectations are developed based upon collateral performance and discounted at an estimated market rate. Significant inputs used to determine the fair value of obligations of states, municipalities and political subdivisions, corporate bonds and obligations of foreign governments include reported trades, benchmark yields, issuer spreads, bids, offers, credit information and estimated cash flows. Significant inputs used to determine the fair value of commercial mortgage-backed securities and residential mortgage-backed securities include the type of underlying assets, benchmark yields, prepayment speeds, collateral information, tranche type and volatility, estimated cash flows, credit information, default rates, recovery rates, issuer spreads and the year of issue.

Senior long-term debt and other debt. Senior long-term debt and other debt is carried at amortized cost with the estimated fair value disclosed on the consolidated balance sheets. Senior long-term debt and other debt is classified as Level 2 within the fair value hierarchy due to variations in trading volumes and the lack of quoted market prices. Fair value is generally derived through recent reported trades, making adjustments through the reporting date, if necessary, based upon available market observable data including U.S. Treasury securities and implied credit spreads. Significant inputs used to determine the fair value of senior long-term debt and other debt include reported trades, benchmark yields, issuer spreads, bids and offers.

5. Equity Method Investments

The Company's equity method investments, which are included in other assets on the consolidated balance sheets, totaled $633.6 million and $605.9 million as of March 31, 2024 and December 31, 2023, respectively. The Company's proportionate share of earnings in its equity method investments was income of $25.9 million and a loss of $1.5 million for three months ended March 31, 2024 and 2023, respectively.

The Company's most significant equity method investment is an investment in Hagerty, Inc. (Hagerty), which is accounted for on a quarter lag. Hagerty is an automotive enthusiast brand offering integrated membership products and programs as well as a specialty insurance provider focused on the global automobile enthusiast market. The Company's ownership interest in Hagerty was 23% as of March 31, 2024 and December 31, 2023. The Company's investment is comprised of Class A common shares, which are listed for trading on the New York Stock Exchange, as well as Class V common shares, associated with the Company's original investment, that have special voting rights and can be converted on a one-for-one basis into Class A common shares. The Company accounts for its investment under the equity method as it is deemed to have the ability to exercise significant influence over Hagerty's operating and financial policies through a combination of its voting interest, its right to designate a board member and business it conducts with Hagerty. As of March 31, 2024 and December 31, 2023, the carrying value of the Company's investment in Hagerty was $238.4 million and $237.4 million, respectively.

As of March 31, 2024 and December 31, 2023, the estimated value of the Company's investment, based on the closing stock price of Hagerty's Class A common shares, was $713.7 million and $608.4 million, respectively. See note 11 for further details regarding related party transactions with Hagerty.

9. Life and Annuity Benefits

The Company's run-off block of life and annuity reinsurance contracts consists primarily of Euro and U.S. Dollar denominated life-contingent payout annuities and traditional and universal life contracts. The following table presents the components of the Company's liabilities for life and annuity benefits.

(dollars in thousands)	March 31, 2024		December 31, 2023
Liability for future policyholder benefits	$	528,249	$	557,763
Deferred profit liability	50,483		52,287
Other	38,534		39,004
Total	$	617,266	$	649,054

18

The primary component of the Company's liabilities for life and annuity benefits is the liability for future policyholder benefits. Life and annuity benefit reserves are calculated for aggregated cohorts of contracts, which are determined based on the attributes of the underlying contracts, and are discounted using standard actuarial techniques and cash flow models. Since the development of the life and annuity reinsurance reserves is based upon cash flow projection models, the Company makes estimates and assumptions based on cedent experience and industry mortality tables. The cash flow assumptions used to determine the Company's life and annuity benefit reserves are reviewed, and updated as necessary, at least annually. The discount rate assumptions are updated at each reporting date. The following table presents a rollforward of the present value of the liability for future policyholder benefits.

	Three Months Ended March 31,
(dollars in thousands)	2024		2023

10. Variable Interest Entities

Markel CATCo Investment Management Ltd. (MCIM), a wholly-owned consolidated subsidiary of the Company, is an insurance-linked securities investment fund manager and reinsurance manager headquartered in Bermuda. Results attributable to MCIM are not included in a reportable segment.

MCIM serves as the insurance manager for Markel CATCo Re Ltd. (Markel CATCo Re), a Bermuda Class 3 reinsurance company, and as the investment manager for Markel CATCo Reinsurance Fund Ltd., a Bermuda exempted mutual fund company comprised of multiple segregated accounts (Markel CATCo Funds). Voting shares in Markel CATCo Reinsurance Fund Ltd. and Markel CATCo Re are held by MCIM, which has the power to direct the activities that most significantly impact the economic performance of these entities. The Markel CATCo Funds issued multiple classes of nonvoting, redeemable preference shares to investors, and the Markel CATCo Funds are primarily invested in nonvoting preference shares of Markel CATCo Re. The underwriting results of Markel CATCo Re are attributed to investors through its nonvoting preference shares. Both Markel CATCo Re and the Markel CATCo Funds were placed into run-off in July 2019.

In 2022, the Company completed a buy-out transaction with Markel CATCo Re and the Markel CATCo Funds that provided for an accelerated return of all remaining capital to investors in the Markel CATCo Funds. Under the terms of the transaction, the Company provided cash funding of $45.1 million to purchase substantially all of the Markel CATCo Funds' interests in Markel CATCo Re. As part of the transaction, substantially all of the preference shares held by investors in the Markel CATCo Funds were redeemed, including preference shares previously held by the Company.

19

The Company has received a return of $24.9 million of the initial cash funding provided, and the related preference shares were redeemed. As of March 31, 2024 and December 31, 2023, the Company's investment in the remaining preference shares of Markel CATCo Re totaled $20.1 million, which comprised 18% and 23%, respectively, of the equity of Markel CATCo Re. Through that investment, the Company has exposure to adverse loss development on reinsurance contracts previously written by Markel CATCo Re for loss events that occurred from 2014 to 2020. If loss reserves held by Markel CATCo Re are sufficient to settle claims on the remaining open contracts, the Company will receive a full return of the remaining $20.1 million in capital. Favorable development on loss reserves held by Markel CATCo Re, less operating expenses, will be distributed to the Markel CATCo Funds, and ultimately to investors in the Markel CATCo Funds.

Markel CATCo Re is considered a VIE, as the equity at risk does not have the right to receive residual returns that exceed the capital provided by the Company in the buy-out transaction. As a result of the preference shares acquired by the Company in the buy-out transaction, and the voting shares held by its consolidated subsidiary, MCIM, the Company consolidates Markel CATCo Re as its primary beneficiary. Results attributed to the run-off of Markel CATCo Re are reported with the Company's other insurance operations, within services and other revenues and expenses, and are not included in a reportable segment. For the three months ended March 31, 2024 and 2023, there was $15.7 million and $44.8 million, respectively, of favorable loss reserve development on the run-off of reinsurance contracts written by Markel CATCo Re, all of which was included in services and other expenses and attributable to noncontrolling interests. During the three months ended March 31, 2023, $62.6 million of preference shares of Markel CATCo Re held by noncontrolling interests were redeemed.

The Company's consolidated balance sheets include the following amounts attributable to Markel CATCo Re.

(dollars in thousands)	March 31, 2024		December 31, 2023
Assets
Cash and cash equivalents	$	96,252	$	91,301
Restricted cash and cash equivalents	169,280		173,800
Other assets and receivables due from cedents	18,742		19,292
Total Assets	$	284,274	$	284,393
Liabilities and Equity
Unpaid losses and loss adjustment expenses	$	168,630	$	184,967
Other liabilities	2,380		1,842
Total Liabilities	171,010		186,809
Shareholders' equity	21,139		21,139
Noncontrolling interests	92,125		76,445
Total Equity	113,264		97,584
Total Liabilities and Equity	$	284,274	$	284,393

In connection with the buy-out transaction, the Company also entered into a tail risk cover with Markel CATCo Re to allow for the release of collateral to investors. Through this contract, the Company has $95.0 million of uncollateralized exposure to adverse development on loss reserves held by Markel CATCo Re for loss exposures in excess of limits that the Company believes are unlikely to be exceeded.

11. Related Party Transactions

The Company engages in certain related party transactions in the normal course of business at arm's length.

Insurance-Linked Securities

Within the Company's insurance-linked securities operations, the Company provides investment and insurance management services through Nephila Holdings Ltd. (together with its subsidiaries, Nephila). Nephila serves as the investment manager to several Bermuda based private funds (the Nephila Funds). To provide access for the Nephila Funds to a variety of insurance-linked securities in the property catastrophe, climate and specialty markets, Nephila also acts as an insurance manager to certain Bermuda Class 3 and 3A reinsurance companies, Lloyd's Syndicate 2357 and Lloyd's Syndicate 2358 (collectively, the Nephila Reinsurers). Nephila receives management fees for investment and insurance management services provided through its insurance-linked securities operations, and, for certain funds, incentive fees based on their annual performance. For the three months ended March 31, 2024 and 2023, total revenues attributed to unconsolidated entities managed by Nephila were $19.2 million and $9.8 million, respectively.

Through the Company's program services and other fronting operations, the Company has programs with Nephila through which the Company writes insurance policies that are fully ceded to the Nephila Reinsurers. Through these programs, Nephila utilizes certain of the Company's licensed insurance companies to write U.S. catastrophe-exposed property and specialty risks that are then ceded to the Nephila Reinsurers. For the three months ended March 31, 2024 and 2023, gross premiums written through the Company's program services and other fronting platforms on behalf of Nephila were $353.1 million and $236.9 million, respectively, all of which were ceded to the Nephila Reinsurers.

As of March 31, 2024 and December 31, 2023, reinsurance recoverables on the consolidated balance sheets included $785.9 million and $794.3 million, respectively, due from the Nephila Reinsurers. Under its programs with the Nephila Reinsurers, the Company bears underwriting risk for annual aggregate agreement year losses in excess of a limit the Company believes is unlikely to be exceeded. To the extent losses under these programs exceed the prescribed limits, the Company is obligated to pay such losses to the cedents without recourse to the Nephila Reinsurers. While the Company believes losses under these programs are unlikely, those losses, if incurred, could be material to the Company's consolidated results of operations and financial condition.

The Company has also entered into other assumed and ceded reinsurance transactions with the Nephila Reinsurers in the normal course of business, which are not material to the Company's consolidated financial statements.

Hagerty

The Company holds a minority ownership interest in Hagerty, which operates primarily as a managing general agent and also includes Hagerty Reinsurance Limited (Hagerty Re), a Bermuda Class 3 reinsurance company. Through the Company's underwriting operations, the Company underwrites insurance for Hagerty, a portion of which is ceded to Hagerty Re. The amounts attributed to these arrangements are summarized in the following table.

	Three Months Ended March 31,
(dollars in thousands)	2024		2023
Gross written premiums attributable to Hagerty	$	198,282	$	164,971
Premiums ceded to Hagerty Re	$	152,685	$	124,628

As of March 31, 2024 and December 31, 2023, reinsurance recoverables on the consolidated balance sheets included $225.3 million and $214.8 million, respectively, due from Hagerty Re.

Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

The following discussion and analysis should be read in conjunction with the consolidated financial statements and related notes included under Item 1 Financial Statements and our 2023 Annual Report on Form 10-K. The accompanying consolidated financial statements and related notes have been prepared in accordance with United States (U.S.) generally accepted accounting principles (GAAP) and include the accounts of our holding company, Markel Group Inc. (Markel Group), and its consolidated subsidiaries, as well as any variable interest entities that meet the requirements for consolidation. This section is divided into the following sections:

•Our Business

•Results of Operations

•Financial Condition

•Critical Accounting Estimates

•Safe Harbor and Cautionary Statement

Our Business

Markel Group is a holding company comprised of a diverse family of businesses and investments. The leadership teams of our businesses operate with a high degree of independence, while at the same time living the values that we call the Markel Style. Our specialty insurance business, Markel, sits at the core of our company. Through decades of sound underwriting, Markel has provided the capital base from which we built a system of businesses and investments that collectively increase Markel Group's durability and adaptability. We aspire to build one of the world's great companies by creating win-win-win outcomes for our customers, associates and shareholders. We deploy three financial engines in pursuit of this goal.

Insurance - markets and underwrites specialty insurance products using our underwriting, fronting and insurance-linked securities platforms that enable us to best match risk and capital

Investments - invests premiums received by our underwriting operations and any available earnings provided by our operating businesses in fixed maturity and equity securities

Markel Ventures - owns controlling interests in a diverse portfolio of businesses that operate in a variety of industries

Our three interdependent engines form a system that provides diverse income streams, access to a wide range of investment opportunities and the ability to efficiently move capital to the best ideas across our three engines. We allocate capital using a process that we have consistently followed for years. We first look to invest in our existing businesses for organic growth opportunities. After funding internal growth opportunities, we look to acquire controlling interests in businesses, build our portfolio of equity securities or repurchase shares of our common stock. We believe our system is uniquely equipped for long-term growth. To mitigate the effects of short-term volatility and align with the long-term perspective that we apply to operating our businesses and making investments, we generally use five-year time periods to measure our performance. We measure financial success using both operating income and total shareholder return. Operating income provides a reasonable proxy for the performance of each engine in support of our overall financial goal of growing intrinsic value. Prior to 2024, we used growth in book value per share, rather than operating income, to measure our performance. As our businesses diversified beyond underwriting operations, book value became less indicative of intrinsic value because a significant portion of our operations is not recorded at fair value. We believe total operating income across the Markel Group system is a better measure of our performance.

Insurance

Our insurance engine is comprised of the following types of operations:

•Underwriting - our risk-bearing insurance and reinsurance operations.

•Program services and other fronting - fronting platform that provides other insurance entities and capacity providers access to the property and casualty insurance market.

•Insurance-linked securities (ILS) - provides investment management services to third-party capital providers for a variety of insurance-related investment products.

23

Through our underwriting, program services and other fronting and ILS operations, we have a suite of capabilities through which we can access capital to support our customers' risks, which includes our own capital through our underwriting operations, as well as third-party capital through our program services and other fronting and ILS operations. Within each of these insurance platforms, we believe that our specialty product focus enables us to develop expertise and specialized market knowledge. We seek to differentiate ourselves from competitors by our expertise, service, continuity and other value-based considerations, including the multiple platforms through which we can manage risk and deploy capital. For example, through our program services and other fronting platform, we have programs through which we write insurance policies on behalf of our ILS operations that are supported by third-party capital. Additionally, we cede certain risks historically written through our underwriting operations to our ILS operations to the extent those risks are more aligned with the risk profile of our ILS investors than our own corporate tolerance. Our ability to access multiple insurance platforms allows us to achieve income streams from our insurance operations beyond the traditional underwriting model. We believe this multi-platform approach provides us with a unique advantage through which we have the ability to unlock additional value for our customers and business partners, which we refer to as "the power of the platform."

Underwriting

We monitor and assess the performance of our ongoing underwriting operations on a global basis in the following two segments: Insurance and Reinsurance. In determining how to allocate resources and assess the performance of our underwriting results, we consider many factors, including the nature of the insurance product sold, the type of account written and the type of customer served. The Insurance segment includes all direct business and facultative reinsurance placements written on a risk-bearing basis within our underwriting operations. The Reinsurance segment includes all treaty reinsurance written on a risk-bearing basis within our underwriting operations.

Our Insurance segment includes unique and hard-to-place risks written on a global basis. In the U.S., this includes business written on an excess and surplus lines basis and an admitted basis. The following products are included in this segment: general liability, professional liability, personal lines, marine and energy, primary and excess of loss property, workers' compensation, credit and surety coverages, specialty program insurance for well-defined markets and liability and other coverages tailored for unique exposures. Business in this segment is primarily written through our Markel Specialty and Markel International divisions.

Our Reinsurance segment includes casualty and specialty treaty reinsurance products offered to other insurance and reinsurance companies. We write quota share and excess of loss reinsurance on a local, national and global basis. Business in this segment is primarily written by our Global Reinsurance division. Principal lines of business include: general liability, professional liability, credit and surety, marine and energy and workers' compensation.

Program Services and Other Fronting

Our program services and other fronting business generates fee income in the form of ceding fees in exchange for fronting insurance and reinsurance business for other insurance carriers, including the Nephila Reinsurers, as defined below. Our program services business, which is provided through our State National division, and our other fronting business are managed separately from our underwriting operations. The results of our program services and other fronting operations are not included in a reportable segment.

Although we reinsure substantially all of the risks inherent in our program services and other fronting businesses, we have certain programs that contain limits on our reinsurers' obligations to us that expose us to underwriting risk, including loss ratio caps, aggregate reinsurance limits or exclusion of the credit risk of producers. Under certain programs, including programs and contracts with the Nephila Reinsurers, we also bear underwriting risk for annual aggregate agreement year losses in excess of a limit that we believe is unlikely to be exceeded. See note 11 of the notes to consolidated financial statements for further details regarding our programs with the Nephila Reinsurers.

Insurance-Linked Securities

Our insurance-linked securities operations are primarily comprised of our Nephila operations and are not included in a reportable segment. Nephila Holdings Ltd. (together with its subsidiaries, Nephila) provides investment and insurance management services through which we offer alternative capital to the insurance and reinsurance market while providing investors with investment strategies that typically are uncorrelated with traditional asset classes. We receive management fees for investment and insurance management services provided through these operations, and for certain funds, incentive fees based on their annual performance.

24

Nephila serves as the investment manager to several Bermuda-based private funds (the Nephila Funds). To provide access for the Nephila Funds to a variety of insurance-linked securities, Nephila acts as an insurance manager to certain Bermuda Class 3, collateralized and special purpose reinsurance companies, Lloyd's Syndicate 2357 and Lloyd's Syndicate 2358 (collectively, the Nephila Reinsurers). The results of the Nephila Reinsurers are attributed to the Nephila Funds primarily through derivative transactions between these entities. Neither the Nephila Funds nor the Nephila Reinsurers are subsidiaries of Markel Group, and as such, these entities are not included in our consolidated financial statements.

The Nephila Reinsurers subscribe to various property, climate, and specialty reinsurance contracts based on their investors' risk profiles, including business ceded by our program services and other fronting platforms. See note 11 of the notes to consolidated financial statements for further details regarding transactions with entities managed through our Nephila operations.

Investments

Our investment operations manage the capital held within our underwriting operations, as well as capital allocated by Markel Group, and are reported as the Investing segment. Invested assets managed through our investment operations include our portfolio of publicly traded fixed maturity and equity securities, as well as cash and short-term investments. Substantially all of our investment portfolio is managed by company employees.

Our underwriting operations provide our investment operations with steady inflows of premiums. These funds are invested predominantly in high-quality government and municipal bonds and mortgage-backed securities that generally match the duration and currency of our loss reserves. We typically hold these investments until maturity. As a result, unrealized holding gains and losses on these securities are generally expected to reverse as the securities mature. Premiums collected through our underwriting operations may also be held as short-term investments or cash and cash equivalents to provide short-term liquidity for projected claims payments, reinsurance costs and operating expenses.

Our investments in equity securities are predominantly held within our regulated insurance subsidiaries to support capital requirements. Capital held by our insurance subsidiaries beyond that which we anticipate will be needed to cover claims payments and operating expenses is available to be invested in equity securities, along with additional capital allocated for investment purposes by Markel Group. We allocate a higher percentage of capital to equity securities than most other insurance companies. Over the long run, equity securities have produced higher returns relative to fixed maturity securities and short-term investments. When purchasing equity securities, we seek to invest in profitable companies with high returns on capital and low debt, with honest and talented management and significant reinvestment opportunities and capital discipline, all while paying reasonable prices for those securities. We intend to hold these equity investments over the long-term.

Markel Ventures

Through our wholly owned subsidiary, Markel Ventures, Inc. (Markel Ventures), we own controlling interests in high-quality businesses that operate in a variety of different industries with shared values and the shared goal of positively contributing to the long-term financial performance of Markel Group. Management teams for each business operate autonomously and are responsible for developing strategic initiatives, managing day-to-day operations and making investment and capital allocation decisions for their respective companies. Our Markel Ventures management team is responsible for decisions regarding allocation of capital for acquisitions and new investments. Our strategy in making these acquisitions is similar to our strategy for purchasing equity securities. We seek to invest in profitable companies, with honest and talented management, that exhibit reinvestment opportunities and capital discipline, at reasonable prices. We intend to own the businesses acquired for a long period of time.

We allocate resources to and assesses the performance of these various businesses in the aggregate as the Markel Ventures segment. The following types of businesses are included in this segment: construction services, consumer and building products, transportation-related products, equipment manufacturing products and consulting services. These businesses offer various types of products and services to businesses and consumers across many markets. All of our businesses in this segment are headquartered in the U.S., with subsidiaries of certain businesses located outside of the U.S.

The increase in operating income and comprehensive income to shareholders for the three months ended March 31, 2024 compared to the three months ended March 31, 2023 was primarily due to pre-tax net investment gains on our equity securities of $906.8 million in 2024 compared to $375.8 million in 2023.

The components of comprehensive income to shareholders are discussed in further detail under "Insurance Results," "Investing Results," "Markel Ventures Results," "Other" and "Comprehensive Income to Shareholders."

Insurance Results

Our Insurance engine includes our underwriting, program services and other fronting and insurance-linked securities (ILS) operations. Our underwriting operations, which are primarily comprised of our Insurance and Reinsurance segments, produce revenues primarily by underwriting insurance contracts and earning premiums in the specialty insurance market. Our program services and other fronting and ILS operations, which are the primary components of our other insurance operations, produce revenues primarily through fees earned for fronting services and investment management services, respectively. Our other insurance operations also include the underwriting results of run-off lines of business that were discontinued prior to, or in conjunction with, insurance acquisitions, and the results of our run-off life and annuity reinsurance business. The following table presents the components of our Insurance engine gross premium volume, operating revenues and operating income.

Underwriting Results

Underwriting profits are a key component of our strategy to build shareholder value. We believe that the ability to achieve consistent underwriting profits demonstrates knowledge and expertise, commitment to superior customer service and the ability to manage insurance risk. The property and casualty insurance industry commonly defines underwriting profit or loss as earned premiums net of losses and loss adjustment expenses and underwriting, acquisition and insurance expenses. We use underwriting profit or loss and the combined ratio as a basis for evaluating our underwriting performance. The U.S. GAAP combined ratio is a measure of underwriting performance and represents the relationship of incurred losses, loss adjustment expenses and underwriting, acquisition and insurance expenses to earned premiums. The combined ratio is the sum of the loss ratio and the expense ratio. The loss ratio represents the relationship of incurred losses and loss adjustment expenses to earned premiums. The expense ratio represents the relationship of underwriting, acquisition and insurance expenses to earned premiums. A combined ratio less than 100% indicates an underwriting profit, while a combined ratio greater than 100% reflects an underwriting loss.

In addition to the U.S. GAAP combined ratio, loss ratio and expense ratio, we also evaluate our underwriting performance using measures that exclude the impacts of certain items, such as catastrophes and other significant, infrequent loss events, on these ratios. During the three months ended March 31, 2024 and 2023, our results were not materially impacted by any such events. When analyzing our loss ratio, we evaluate losses and loss adjustment expenses attributable to the current accident year separate from losses and loss adjustment expenses attributable to prior accident years. Prior accident year reserve development, which can either be favorable or unfavorable, represents changes in our estimates of losses and loss adjustment expenses related to loss events that occurred in prior years. We believe a discussion of current accident year loss ratios, which exclude prior accident year reserve development, is helpful since it provides more insight into estimates of current underwriting performance and excludes changes in estimates related to prior year loss reserves.

The following table presents summary data for our consolidated underwriting operations, which are comprised predominantly of our Insurance and Reinsurance segments. Our consolidated underwriting results also include results from discontinued lines of business and the retained portion of our program services and other fronting operations.

Premiums

The increase in gross premium volume in our underwriting operations for the three months ended March 31, 2024 was driven by targeted growth within our Insurance segment. Net retention of gross premium volume in our underwriting operations was 80% for the three months ended March 31, 2024 compared to 83% for the same period of 2023. The decrease in net retention for the three months ended March 31, 2024 was driven by lower retention across both of our underwriting segments. Within our underwriting operations, we purchase reinsurance and retrocessional reinsurance to manage our net retention on individual risks and overall exposure to losses and to enable us to write policies with sufficient limits to meet policyholder needs. The increase in earned premiums in our underwriting operations for the three months ended March 31, 2024 was primarily attributable to higher gross premium volume within our Insurance segment in recent periods.

In the first quarter of 2024, we continued to achieve modest rate increases across our diversified product portfolio. Similar to 2023, the primary exceptions where we are seeing modest rate decreases are within our workers' compensation, public directors and officers and cyber portfolios, which is consistent with the broader market trends in these product classes. We examine each of our product classes regularly by evaluating pricing and exposure, underwriting terms and conditions, deal structure, including limits and attachment points, and our expectations around loss cost trends, among other things. We target premium growth only in product lines where we are confident in the levels of rate adequacy.

We continued to achieve significant, but moderating, levels of rate increases within our personal lines, property and select marine and energy product lines, and they continue to produce profitable underwriting results. As a result, we are increasing our premium writings in these lines. Additionally, we achieved notable rate increases within many of our general liability product lines, and these rate increases are generally in line with, or better than, our assumptions on loss cost trends. We are being cautious in selecting which risks to pursue and are being intentional around pricing requirements, as well as rate adequacy and portfolio management considerations, as we rebalance our general liability portfolio and focus on growth in areas of the portfolio that we project will meet our profitability requirements.

Within our insurance and reinsurance professional liability product lines, overall, we saw modest rate decreases driven by the continued rate decreases within our public directors and officers product line. Within this product line, we are contracting our new premium writings when we believe rates are inadequate and are also allowing business to lapse. In other professional liability product lines, particularly within our international portfolio and our U.S. commercial book, we are generally seeing downward pressure on rates persist in 2024; however, these pockets of the portfolio have performed well overall, and we are continuing to pursue growth opportunities where we find the business to be adequately priced. During the first quarter of 2024, we discontinued writing our risk-managed architects and engineers and intellectual property collateral protection product lines within our professional liability portfolio due to these products being unable to meet our profitability targets.

28

Combined Ratio

For the three months ended March 31, 2024, the increase in our consolidated combined ratio compared to the same period of 2023 was primarily attributable to a higher attritional loss ratio within our Insurance segment.

Premiums

The increase in gross premium volume in our Insurance segment for the three months ended March 31, 2024 was driven by new business growth and more favorable rates within our personal lines and programs product lines, as well as increases on most classes of our international portfolio, partially offset by lower premium volume within select lines of our U.S. professional liability and general liability product lines. We have decreased writings within our risk-managed directors and officers professional liability product and our brokerage contractors, brokerage excess and umbrella and risk-managed excess casualty general liability products in response to underwriting actions aimed at achieving greater profitability within these product lines.

Net retention of gross premium volume was 79% for the three months ended March 31, 2024 compared to 81% for the same period of 2023. The decrease in net retention for the three months ended March 31, 2024 was driven by higher cessions on our professional liability product lines in 2024 compared to 2023.

The increase in earned premiums for the three months ended March 31, 2024 was primarily due to higher gross premium volume across most product lines in recent periods.

Combined Ratio

The increase in the Insurance segment's current accident year loss ratio for the three months ended March 31, 2024 compared to the same period of 2023 was primarily attributable to higher attritional loss ratios within our U.S. general liability and professional liability product lines. We have increased our attritional loss ratios on certain product classes within our general liability and professional liability product lines in response to unfavorable loss development trends in recent periods on these long-tail lines of business and uncertainty around future loss cost trends.

The Insurance segment's combined ratio for the three months ended March 31, 2024 included $97.2 million of favorable development on prior accident years loss reserves compared to $62.6 million for the same period of 2023. The increase in favorable development was primarily attributable to favorable development on our general liability and professional liability product lines in 2024 compared to minimal development on these lines in 2023. For the three months ended March 31, 2024, favorable development was most significant on more recent accident years within our international professional liability and marine and energy product lines, as well as on our general liability product lines. Despite net favorable development on these long-tail lines, we continue to approach reductions of prior year loss reserves on our longer tail U.S. professional liability and general liability product lines with caution given recent claims trend. The favorable development on prior years loss reserves in 2023 was most significant on our marine and energy, property, workers' compensation and programs product lines.

29

The modest increase in the Insurance segment's expense ratio for the three months ended March 31, 2024 compared to the same period of 2023 was primarily attributable to higher personnel costs, professional fees and other general and administrative expenses, which were largely offset by a lower policy acquisition cost ratio and the favorable impact of higher earned premiums.

Premiums

For the three months ended March 31, 2024 and 2023, gross premium volume in the Reinsurance segment was consistent. Higher gross premiums within our marine and energy, general liability and credit and surety product lines were offset by a significant decline in gross premiums within our professional liability product lines. Higher gross premiums within our marine and energy and general liability product lines were primarily due to increases on renewals, due to increased participation and exposures, as well as new business. Higher gross premiums within our credit and surety product lines were primarily driven by favorable timing differences on multi-year contracts. Lower gross premiums within our professional liability product lines were primarily due to the non-renewal of certain significant contracts and unfavorable timing differences. The non-renewals within our professional liability product lines were the result of our continued focus on rate adequacy and only writing business that meets our underwriting profit targets. The unfavorable timing differences within our professional liability product lines were the result of two large contracts written in the first quarter of 2023 that we expect to renew in the second quarter of 2024. Significant variability in gross premium volume can be expected in our Reinsurance segment due to individually significant contracts and multi-year contracts.

Net retention of gross premium volume for the three months ended March 31, 2024 was 86% compared to 93% for the same period of 2023. The decrease in net retention for the three months ended March 31, 2024 was driven by changes in mix of gross premium volume, as our professional liability business is fully retained and our marine and energy business carries a higher cession rate than the rest of the segment.

The decrease in earned premiums for the three months ended March 31, 2024 was primarily due to lower gross premium volume within our professional liability product lines, partially offset by higher gross premium volume within our general liability product lines in recent periods.

30

Combined Ratio

The Reinsurance segment's combined ratio for the three months ended March 31, 2024 included a $3.4 million increase in prior accident years loss reserves, which was primarily attributable to additional exposures recognized on prior accident years related to net favorable premium adjustments on our general liability and professional liability product lines. For the three months ended March 31, 2023, the combined ratio included $8.7 million of favorable development on prior accident years loss reserves, which was primarily attributable to modest favorable development on our professional liability and property product lines across several accident years. This favorable development in the first quarter of 2023 was partially offset by additional exposures recognized on prior accident years related to net favorable premium adjustments on our general liability product lines.

Other Insurance Operations

The following table presents the components of operating revenues and operating income attributable to our other insurance operations, which are not included in a reportable segment. We do not allocate amortization of acquired intangible assets to our operating segments, including our other insurance operations.

(3)    Underwriting results attributable to our other insurance operations include results from discontinued lines of business and the retained portion of our program services and other fronting operations.

Program Services and Other Fronting

The increase in operating revenues and operating income within our program services and other fronting operations for the three months ended March 31, 2024 was due to higher gross premium volume in 2024 compared to the same period of 2023. The following table summarizes gross premium volume in our program services and other fronting operations.

	Three Months Ended March 31,
(dollars in thousands)	2024		2023		% Change
Program services	$	855,404	$	619,350	38	%
Other fronting	$	308,829	$	158,404	95	%

The increase in gross premium volume within our program services operations for the three months ended March 31, 2024 was primarily attributable to expansion of existing programs and growth from new programs. The increase in gross premium volume in our other fronting operations for the three months ended March 31, 2024 was driven by growth of our property catastrophe and specialty programs with the Nephila Reinsurers.

Insurance-Linked Securities

The increase in operating revenues in our Nephila insurance-linked securities operations for the three months ended March 31, 2024 was primarily due to changes in the mix of investment products within the funds. Nephila's net assets under management were $6.8 billion as of March 31, 2024.

31

Underwriting

For the three months ended March 31, 2024, the underwriting operating loss in our other insurance operations was primarily attributable to loss adjustment expenses related to asbestos and environmental exposures. Development on asbestos and environmental loss reserves is monitored separately from our ongoing underwriting operations and is not included in the Insurance or Reinsurance segments.

Investing Results

We measure our investment performance by analyzing net investment income, which reflects the recurring interest and dividend earnings on our investment portfolio. We also analyze net investment gains, which include unrealized gains and losses on our equity portfolio. Based on the potential for volatility in the financial markets, we understand that the level of gains or losses may vary from one period to the next, and therefore believe that our investment performance is best analyzed over longer periods of time. As of March 31, 2024, the fair value of our equity portfolio included cumulative unrealized gains of $7.0 billion.

The following table summarizes our consolidated investment performance, which consists predominantly of the results of our Investing segment. Net investment gains or losses in any given period are typically attributable to changes in the fair value of our equity portfolio due to market value movements. The change in net unrealized losses on available-for-sale investments in any given period is typically attributable to changes in the fair value of our fixed maturity portfolio due to changes in interest rates during the period. As of March 31, 2024, 98% of our fixed maturity portfolio was rated "AA" or better.

	Three Months Ended March 31,

Net investment income	$	218,269		$	159,335
Yield on fixed maturity securities (1)	3.2		%	2.5		%
Yield on short-term investments (1)	5.0		%	4.0		%
Yield on cash and cash equivalents and restricted cash and cash equivalents (1)	3.5		%	2.0		%

Other (3)	$	20,846		$	(2,380)
Change in net unrealized losses on available-for-sale investments	$	(155,769)		$	208,369

(1)    Yields reflect the applicable annualized interest income as a percentage of the applicable monthly average invested assets at amortized cost.

(2)    Return on equity securities is calculated by dividing dividends and the change in fair value of equity securities by the monthly average equity securities at fair value and considers the timing of net purchases and sales.

(3)    Other income or losses within our investing operations primarily relate to equity method investments in our investing segment, which are managed separately from the rest of our investment portfolio.

For the three months ended March 31, 2024, net investment income increased 37%, primarily driven by higher interest income on fixed maturity securities due to a higher yield and higher average holdings of fixed maturity securities in 2024 compared to 2023. During 2024, we have continued to allocate cash and short-term investments to fixed maturity securities to take advantage of high interest rates and to support our growing underwriting business. Additionally, interest income on our cash equivalents and short-term investments increased due to higher short-term interest rates and a higher portion of our cash being invested in money market funds during the three months ended March 31, 2024 compared to the same period of 2023. See note 3(d) of the notes to consolidated financial statements for details regarding the components of net investment income.

Markel Ventures Results

We measure the operating performance of our Markel Ventures segment by its operating income, as well as earnings before interest, income taxes, depreciation and amortization (EBITDA). We consolidate the results of our Markel Ventures subsidiaries on a one-month lag, with the exception of significant transactions or events that occur during the intervening period. The following table summarizes the results from our Markel Ventures segment.

	Three Months Ended March 31,
(dollars in thousands)	2024		2023		% Change
Operating revenues	$	1,140,606	$	1,104,680	3	%
Segment operating income	$	103,915	$	92,178	13	%
EBITDA	$	133,645	$	119,541	12	%

The increase in operating revenues for the three months ended March 31, 2024 compared to the same period of 2023 was driven by moderately higher revenues at our consumer and building products businesses, construction services businesses and transportation-related businesses, due to a combination of increased demand and higher prices. These increases in operating revenues were partially offset by the impact of delayed shipments at one of our equipment manufacturing businesses and decreased demand at one of our construction services businesses.

The increases in segment operating income and EBITDA for the three months ended March 31, 2024 compared to the same period of 2023 were driven by the impact of higher operating margins at our consumer and building products businesses as a result of declines in the cost of materials, freight and labor, as well as higher revenues. These increases were partially offset by the impact of lower revenues and operating margins at one of our construction services businesses due to decreased demand.

Markel Ventures segment EBITDA is a non-GAAP financial measure. We use Markel Ventures segment EBITDA as an operating performance measure in conjunction with our segment performance metric, segment operating income, to monitor and evaluate the performance of our Markel Ventures segment. Because EBITDA excludes interest, income taxes, depreciation and amortization, it provides an indicator of economic performance that is useful to both management and investors in evaluating our Markel Ventures businesses as it is not affected by levels of debt, interest rates, effective tax rates or levels of depreciation or amortization resulting from purchase accounting. The following table reconciles Markel Ventures segment operating income to EBITDA.

	Three Months Ended March 31,
(dollars in thousands)	2024		2023
Markel Ventures segment operating income	$	103,915	$	92,178
Depreciation expense	29,730		27,363
Markel Ventures segment EBITDA	$	133,645	$	119,541

Other

The following table presents the components of consolidated net income that are not allocated to our operating segments.

	Three Months Ended March 31,
(dollars in thousands)	2024			2023

Income tax expense	$	292,556		$	133,731
Effective tax rate	22		%	20		%

Interest Expense

The decrease in interest expense for the three months ended March 31, 2024 was attributable to the impact of the retirement of our 3.625% unsecured senior notes in March 2023 and lower debt held by our Markel Ventures subsidiaries.

Net Foreign Exchange Gains (Losses)

Net foreign exchange gains (losses) are primarily due to the remeasurement of our foreign currency denominated insurance loss reserves to the U.S. Dollar. The predominant foreign currencies within our insurance operations are the British Pound and the Euro. The U.S. Dollar strengthened against the Euro and British Pound during the first quarter of 2024, while it weakened against the British Pound and Euro during the first quarter of 2023. Pre-tax net foreign exchange gains and losses attributed to changes in exchange rates on available-for-sale securities supporting our insurance reserves, which are included in the changes in net unrealized losses on available-for-sale investments in other comprehensive income (loss), were losses of $42.4 million and gains of $33.9 million for the three months ended March 31, 2024 and 2023, respectively.

Income Taxes

The increase in the effective tax rate for the three months ended March 31, 2024 compared to the same period of 2023 was due to higher state taxes and a decrease in Markel CATCo Re income not subject to tax in 2024 compared to 2023.

Comprehensive Income to Shareholders

Financial Condition

Liquidity and Capital Resources

We seek to maintain prudent levels of liquidity and financial leverage for the benefit and protection of our policyholders, creditors and shareholders. Our consolidated debt to capital ratio was 20% at March 31, 2024 and December 31, 2023, which is within the range of our target capital structure.

Investments, cash and cash equivalents and restricted cash and cash equivalents (invested assets) were $32.0 billion and $30.9 billion at March 31, 2024 and December 31, 2023, respectively. The following table presents the composition of our invested assets.

	March 31, 2024		December 31, 2023
Fixed maturity securities	45	%	47	%
Equity securities	33	%	31	%
Short-term investments, cash and cash equivalents and restricted cash and cash equivalents	22	%	22	%
Total	100	%	100	%

Our holding company had $3.6 billion and $3.5 billion of invested assets at March 31, 2024 and December 31, 2023, respectively. The increase was primarily due to an increase in the fair value of equity securities held by our holding company, largely offset by cash used to repurchase shares of our common stock. The following table presents the composition of our holding company's invested assets.

	March 31, 2024		December 31, 2023
Fixed maturity securities	4	%	4	%
Equity securities	54	%	49	%
Short-term investments, cash and cash equivalents and restricted cash and cash equivalents	42	%	47	%
Total	100	%	100	%

We have a share repurchase program, authorized by our Board of Directors, that provides for the repurchase of up to $750 million of common stock. As of March 31, 2024, $553.5 million remained available for repurchases under the program. This share repurchase program has no expiration date but may be terminated by the Board of Directors at any time.

We may from time to time seek to prepay, retire or repurchase our outstanding senior notes or preferred shares, through open market purchases, privately negotiated transactions or otherwise. Those prepayments, retirements or repurchases, if any, will depend on prevailing market conditions, our liquidity requirements, contractual restrictions and other factors.

We have access to various capital sources, including dividends from our subsidiaries, holding company invested assets, undrawn capacity under our revolving credit facility and access to the debt and equity capital markets. We believe we have, or have access to, adequate liquidity to meet our capital and operating needs, including that which may be required to support the operating needs of our subsidiaries. However, the availability of these sources of capital and the availability and terms of future financings will depend on a variety of factors.

Cash Flows

Net cash provided by operating activities was $630.7 million for the three months ended March 31, 2024 compared to $284.2 million for the same period of 2023. The increase in net cash flows from operating activities for the three months ended March 31, 2024 compared to the same period in 2023 was due in part to higher net premium collections. Additionally, during the three months ended March 31, 2023, a payment of $125.1 million was made to complete a retroactive reinsurance transaction to cede our portfolio of policies comprised of liabilities related to our run-off book of U.K. motor casualty business.

Net cash used by investing activities was $564.2 million for the three months ended March 31, 2024 compared to $108.5 million for the same period of 2023. During the three months ended March 31, 2024, net cash used by investing activities included net purchases of fixed maturity securities, equity securities and short-term investments of $333.2 million, $86.2 million and $21.4 million, respectively. During the three months ended March 31, 2023, net cash used by investing activities included net purchases of fixed maturity securities and equity securities of $214.7 million and $65.1 million, respectively, and net sales of short-term investments of $210.2 million. Cash flows from investing activities is affected by various factors such as anticipated payment of claims, financing activity, acquisition opportunities and individual buy and sell decisions made in the normal course of our investment portfolio management.

Net cash used by financing activities was $102.7 million for the three months ended March 31, 2024 compared to $412.2 million for the same period of 2023. Cash of $160.9 million and $82.0 million was used to repurchase shares of our common stock during the first three months of 2024 and 2023, respectively. During the three months ended March 31, 2023, net cash used by financing activities included $250.0 million to retire our 3.625% unsecured senior notes due March 30, 2023. Additionally, financing activities during the three months ended March 31, 2024 and 2023 reflected borrowings and repayments of debt at certain our Markel Ventures businesses, primarily on revolving lines of credit.

Critical Accounting Estimates

Critical accounting estimates are those estimates that both are important to the portrayal of our financial condition and results of operations and require us to exercise significant judgment. The preparation of financial statements in accordance with U.S. GAAP requires us to make estimates and assumptions that affect the reported amounts of assets, liabilities, revenues and expenses and the disclosure of material contingent assets and liabilities. These estimates, by necessity, are based on assumptions about numerous factors.

Our critical accounting estimates consist of estimates and assumptions used in determining the reserves for unpaid losses and loss adjustment expenses as well as estimates and assumptions used in the valuation of goodwill and intangible assets. We review the adequacy of reserves for unpaid losses and loss adjustment expenses quarterly. Estimates and assumptions for goodwill and intangible assets are reviewed in conjunction with acquisitions and impairment assessments. Goodwill and indefinite-lived intangible assets are reassessed for impairment at least annually. All intangible assets, including goodwill, are also reviewed for impairment when events or circumstances indicate that their carrying value may not be recoverable. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

Readers are urged to review our 2023 Annual Report on Form 10-K for a more complete description of our critical accounting estimates.

Safe Harbor and Cautionary Statement

This report contains statements concerning or incorporating our expectations, assumptions, plans, objectives, future financial or operating performance and other statements that are not historical facts. These statements are "forward-looking statements" within the meaning of the Private Securities Litigation Reform Act of 1995. Such statements may use words such as "anticipate," "believe," "estimate," "expect," "intend," "predict," "project" and similar expressions as they relate to us or our management.

There are risks and uncertainties that may cause actual results to differ materially from predicted results in forward-looking statements. Factors that may cause actual results to differ are often presented with the forward-looking statements themselves. Additional factors that could cause actual results to differ from those predicted are set forth under "Business," "Risk Factors," "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Quantitative and Qualitative Disclosures About Market Risk" in our 2023 Annual Report on Form 10-K or under "Management's Discussion and Analysis of Financial Condition and Results of Operations" and "Quantitative and Qualitative Disclosures About Market Risk" in this report, or are included in the items listed below:

•our efforts to develop new products, expand in targeted markets or improve business processes and workflows may not be successful and may increase or create new risks (e.g., insufficient demand, change to risk exposures, distribution channel conflicts, execution risk, regulatory risk, increased expenditures);

•the frequency and severity of man-made, health-related and natural catastrophes may exceed expectations, are unpredictable and, in the case of some natural catastrophes, may be exacerbated by changing conditions in the climate, oceans and atmosphere, resulting in increased frequency and/or severity of extreme weather-related events;

•we offer insurance and reinsurance coverage against terrorist acts in connection with some of our programs, and in other instances we are legally required to offer terrorism insurance; in both circumstances, we actively manage our exposure, but if there is a covered terrorist attack, we could sustain material losses;

•emerging claim and coverage issues, changing industry practices and evolving legal, judicial, social and other claims and coverage trends or conditions, can increase the scope of coverage, the frequency and severity of claims and the period over which claims may be reported; these factors, as well as uncertainties in the loss estimation process, can adversely impact the adequacy of our loss reserves and our allowance for reinsurance recoverables;

•reinsurance reserves are subject to greater uncertainty than insurance reserves, primarily because of reliance upon the original underwriting decisions made by ceding companies and the longer lapse of time from the occurrence of loss events to their reporting to the reinsurer for ultimate resolution;

•inaccuracies (whether due to data error, human error or otherwise) in the various modeling techniques and data analytics (e.g., scenarios, predictive and stochastic modeling, and forecasting) we use to analyze and estimate exposures, loss trends and other risks associated with our insurance and insurance-linked securities businesses could cause us to misprice our products or fail to appropriately estimate the risks to which we are exposed;

•changes in the assumptions and estimates used in establishing reserves for our life and annuity reinsurance book (which is in runoff), for example, changes in assumptions and estimates of mortality, longevity, morbidity and interest rates, could result in material changes in our estimated loss reserves for that business;

•adverse developments in insurance coverage litigation or other legal or administrative proceedings could result in material increases in our estimates of loss reserves;

•initial estimates for catastrophe losses and other significant, infrequent events are often based on limited information, are dependent on broad assumptions about the nature and extent of losses, coverage, liability and reinsurance, and those losses may ultimately differ materially from our expectations;

•changes in the availability, costs, quality and providers of reinsurance coverage, which may impact our ability to write, or continue to write, certain lines of business or to mitigate the volatility of losses on our results of operations and financial condition;

•the ability or willingness of reinsurers to pay balances due may be adversely affected by industry and economic conditions, deterioration in reinsurer credit quality and coverage disputes, and collateral we hold, if any, may not be sufficient to cover a reinsurer's obligation to us;

•after the commutation of ceded reinsurance contracts, any subsequent adverse development in the re-assumed loss reserves will result in a charge to earnings;

•regulatory actions can impede our ability to charge adequate rates and efficiently allocate capital;

•general economic and market conditions and industry specific conditions, including: extended economic recessions or expansions; prolonged periods of slow economic growth; inflation or deflation; fluctuations in foreign currency exchange rates, commodity and energy prices and interest rates; volatility in the credit and capital markets; and other factors;

•economic conditions, actual or potential defaults in corporate bonds, municipal bonds, mortgage-backed securities or sovereign debt obligations, volatility in interest and foreign currency exchange rates, changes in U.S. government debt ratings and changes in market value of concentrated investments can have a significant impact on the fair value of our fixed maturity securities and equity securities, as well as the carrying value of our other assets and liabilities, and this impact may be heightened by market volatility and our ability to mitigate our sensitivity to these changing conditions;

37

•economic conditions may adversely affect our access to capital and credit markets;

•the effects of government intervention, including material changes in the monetary policies of central banks, to address financial downturns, inflation and other economic and currency concerns;

•the impacts that political and civil unrest and regional conflicts may have on our businesses and the markets they serve or that any disruptions in regional or worldwide economic conditions generally arising from these situations may have on our businesses, industries or investments;

•the impacts of liability, transition and physical risks associated with climate change;

•the significant volatility, uncertainty and disruption caused by health epidemics and pandemics, as well as governmental, legislative, judicial or regulatory actions or developments in response thereto;

•changes in U.S. tax laws, regulations or interpretations, or in the tax laws, regulations or interpretations of other jurisdictions in which we operate, and adjustments we may make in our operations or tax strategies in response to those changes;

•a failure or security breach of, or cyberattack on, enterprise information technology systems that we, or third parties who perform certain functions for us, use or a failure to comply with data protection or privacy regulations;

•third-party providers may perform poorly, breach their obligations to us or expose us to enhanced risks;

•our acquisitions may increase our operational and internal control risks for a period of time;

•we may not realize the contemplated benefits, including cost savings and synergies, of our acquisitions;

•any determination requiring the write-off of a significant portion of our goodwill and intangible assets;

•the failure or inadequacy of any methods we employ to manage our loss exposures;

•the loss of services of any senior executive or other key personnel, or an inability to attract and retain qualified personnel, for our businesses could adversely impact one or more of our operations;

•regulatory changes, or challenges by regulators, regarding the use of certain issuing carrier or fronting arrangements;

•our dependence on a limited number of brokers for a large portion of our revenues and third-party capital;

•adverse changes in our assigned financial strength, debt or preferred share ratings or outlook could adversely impact us, including our ability to attract and retain business, the amount of capital our insurance subsidiaries must hold and the availability and cost of capital;

•changes in the amount of statutory capital our insurance subsidiaries are required to hold, which can vary significantly and is based on many factors, some of which are outside our control;

•losses from litigation and regulatory investigations and actions; and

38

•a number of additional factors may adversely affect our Markel Ventures businesses, and the markets they serve, and negatively impact their revenues and profitability, including, among others: adverse weather conditions, plant disease and other contaminants; changes in government support for education, healthcare and infrastructure projects; changes in capital spending levels; changes in the housing, commercial and industrial construction markets; liability for environmental matters; supply chain and shipping issues, including increases in freight costs; volatility in the market prices for their products; and volatility in commodity, wholesale and raw materials prices and interest and foreign currency exchange rates.

Results from our Insurance, Investments and Markel Ventures operations have been and will continue to be potentially materially affected by these factors.

By making forward-looking statements, we do not intend to become obligated to publicly update or revise any such statements whether as a result of new information, future events or other changes. Readers are cautioned not to place undue reliance on any forward-looking statements, which are based on our current knowledge and speak only as at their dates.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Market risk is the risk of economic losses due to adverse changes in the estimated fair value of a financial instrument as the result of changes in equity prices, interest rates, foreign currency exchange rates and commodity prices. Our consolidated balance sheets include assets and liabilities with estimated fair values that are subject to market risk. Our primary market risks are equity price risk associated with investments in equity securities, interest rate risk associated with investments in fixed maturity securities and foreign currency exchange rate risk associated with our international operations. During the three months ended March 31, 2024, there were no material changes in our market risk exposures from those described in our 2023 Annual Report on Form 10-K.

Credit Risk

Credit risk, which is not considered a market risk, is the risk that an entity becomes unable or unwilling to fulfill their obligations to us. Our primary credit risks are the credit risk within our fixed maturity portfolio and the credit risk related to our reinsurance recoverables within our underwriting, program services and other fronting operations. During the three months ended March 31, 2024, there were no material changes in our credit risk exposures from those described in our 2023 Annual Report on Form 10-K.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

As of the end of the period covered by this quarterly report, we evaluated the effectiveness of the design and operation of our disclosure controls and procedures (Disclosure Controls), as defined under Rules 13a-15(e) and 15d-15(e) of the Securities Exchange Act of 1934 (Exchange Act). This evaluation was conducted under the supervision and with the participation of our management, including the Principal Executive Officer (PEO) and the Principal Financial Officer (PFO).

Based upon this evaluation, the PEO and PFO concluded that effective Disclosure Controls were in place to ensure that the information required to be disclosed in reports we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the Securities and Exchange Commission's rules and forms.

Changes in Internal Control over Financial Reporting

During the first quarter of 2024, we implemented a new instance of our enterprise resource planning system that included certain structural changes in our ledger design. The new instance allows for improved performance and functionality and provides scalability for future growth. Throughout the transition and upon implementation of the new instance, we evaluated the impact of the new instance on our internal controls over financial reporting and made updates to controls as necessary.

There were no other changes in our internal control over financial reporting during the first quarter of 2024 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

Item 1. Legal Proceedings

Thomas Yeransian v. Markel Group Inc.

We previously reported that Thomas Yeransian, in his capacity as the representative of holders of certain contingent value rights, filed three suits against the Company:

•Thomas Yeransian v. Markel Corporation (U.S. District Court for the District of Delaware), filed September 15, 2016;

•Thomas Yeransian v. Markel Corporation (U.S. District Court for the District of Delaware), filed November 13, 2018; and

•Thomas Yeransian v. Markel Corporation (U.S. District Court for the District of Delaware), filed June 5, 2020.

The three suits were consolidated. On June 8, 2023, the court ruled in favor of the Company and against Mr. Yeransian on all counts. On July 7, 2023, Mr. Yeransian appealed the court's decision to the United States Court of Appeals for the Third Circuit. For additional information regarding these three suits, see Item 3 Legal Proceedings in our 2023 Annual Report on Form 10-K. We believe Mr. Yeransian's suits to be without merit. We further believe that any material loss resulting from the suits to be remote.
