PART I

Item 1. BUSINESS

Markel Group is a holding company that owns independently operated businesses across a range of industries. The cornerstone business, Markel Insurance, provides specialized insurance products that are not typically available through the standard insurance market. This insurance business sits at the center of the Company's strategy. It generates and holds capital used to support growth and investment across Markel Group. The other majority-owned businesses operate in diverse end markets, from industrial bakery equipment to ornamental plants to precast concrete. Markel Group also owns shares in publicly traded companies, primarily within its insurance operations.

Markel Group supports each business by empowering leaders to make the best long-term decisions for their businesses. Customers, associates, and shareholders each benefit from this approach, given how it allows businesses to pursue opportunities that require time, stability, and trust. We believe this approach is difficult to replicate and makes Markel Group a distinctive home for businesses.

An example of Markel Group's long-term mindset is the approach to reserving within the insurance operations. Customers rely on Markel Insurance to honor promises that may extend many years into the future. Through its long-standing practice of establishing reserves that are more likely to be redundant than deficient and investing the capital held to pay those reserves in high-quality investments, Markel Insurance ensures it can fulfill its commitments and uphold the trust placed in it by policyholders.

The Company's architecture is intentionally designed to promote long-term decision making. Diverse cash flows across Markel Group provide financial strength. If one business faces headwinds, others can continue generating cash flow, enabling the Company to continuously pursue attractive opportunities. Low levels of debt reduce outside pressures that could otherwise force short-term actions. Decentralized leadership allows each business to adapt quickly to best serve its customers.

This long-term orientation is rooted in, and guided by, the Company's culture, known as The Markel Style. The Markel Style is built on simple ideas: treat people fairly, act with integrity, and commit to winning over the long term. These principles guide decisions across the Company, serving as a shared set of values that foster excellence and consistency across independent businesses, all while allowing each business to retain its entrepreneurial spirit.

Relentlessly Compounding Shareholder Capital

A key principle of The Markel Style is building the value of the Company for shareholders. The design of Markel Group supports this goal by (i) owning businesses that generate positive cash flows and (ii) redeploying those cash flows for additional growth.

Achieving this goal requires the ability to redeploy capital efficiently, with low friction and at attractive rates, across a large and diverse opportunity set. Markel Group has developed the skill and capability to do so in multiple ways:

•Reinvesting in existing businesses

•Acquiring majority-owned businesses

•Investing in publicly traded companies

•Repurchasing Markel Group shares

In making new investments, Markel Group applies the same four-part test that has guided it for decades, regardless of where capital is deployed. The Company looks for businesses with:

•Good returns on capital while using modest amounts of debt

•Management teams with equal parts talent and integrity

•Meaningful opportunities for reinvestment and/or disciplined capital management

•A fair price

This unique company design and set of shared values have enabled the Company to compound shareholder capital at attractive rates over many decades. We believe this compounding is best exhibited by the five-year compound annual growth rate (CAGR) in our closing stock price and intrinsic value per share, which were 16% and 15%, respectively.

Key Financial Metrics

We believe our system is uniquely equipped to relentlessly compound shareholder capital at attractive rates across decades. To better align with this long-term perspective, we use five-year time periods to measure our performance. The following table presents a summary of key financial metrics over the last five years.

See "Capital Performance" under Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations for additional information on this metric. Markel Insurance's 5-year average annual return on equity is presented beginning in 2024 due to the impracticality of calculating return on equity prior to 2020 for the newly defined Markel Insurance segment.

(3) Markel Insurance total investment return reflects net investment income and net investment gains and losses attributed to investments held by Markel Insurance as a percentage of monthly average invested assets.

(4) Organic revenue growth is a non-GAAP financial measure. See "Non-GAAP Financial Measures" for additional information on this metric.

(5) Total capital is comprised of total equity, redeemable noncontrolling interests, total debt, and obligations for finance leases. Tangible capital represents total capital less goodwill and intangible assets, net of deferred taxes.

Markel Insurance

Markel Insurance, headquartered in Richmond, Virginia, is a specialty insurance business comprised of empowered local leaders underwriting hard-to-place risks across the globe in service of their customers' needs. Markel Insurance generates income primarily through its core underwriting activities and by investing the capital held in its underwriting subsidiaries. Markel Insurance's operations also include other insurance-related activities, including fronting and strategic minority investments.

In evaluating the overall returns of our Markel Insurance business, we consider all returns generated by the business, which are driven by underwriting profits and investment earnings. We seek to earn consistent underwriting profits, which we believe demonstrates the value customers place on our knowledge and expertise, our commitment to superior customer service, and our ability to manage insurance risk. Markel Insurance produced a combined ratio of 95% in 2025, making it the eighteenth year in the last 20 years that we earned an underwriting profit.

Within the investment operations of Markel Insurance, we seek to both protect policyholder funds with investments in high-quality fixed maturity securities and to compound shareholder capital through long-term investments in public equity securities. Our investment strategy, which is led by the Markel Group Chief Executive Officer (CEO), prioritizes long-term value creation by allocating a substantial portion of the Markel Insurance investment portfolio to equity securities. While this strategy is designed to generate long-term returns in excess of those typically available from fixed maturity securities, volatility in mark-to-market gains and losses on equity securities can distort Markel Insurance's short-term results. As a result, we exclude these gains and losses when assessing Markel Insurance's periodic segment profit and only include them when assessing the overall capital efficiency and long-term returns of the business.

Over the past five years, Markel Insurance produced an average annual return on equity of 13%.

Markel Insurance is comprised of the following divisions through which our underwriting and other insurance-related activities are conducted.

•U.S. Wholesale and Specialty: Offers specialty insurance in the United States (U.S.) on a regional basis through wholesale and retail channels on both an excess and surplus (E&S) and admitted basis, as well as on a small account binding authority basis through providing limited delegated underwriting authority. In 2025, 71% of gross written premium was placed through wholesale brokers and 26% was distributed through retail agents and brokers with the remaining premium placed through alternative distribution channels.

•Program and Solutions: Offers a portfolio of highly specialized insurance products in the U.S. written on both an admitted and E&S basis, as well as specialty lines written from its Bermuda platform. Business units within this division include Personal Lines, Surety, Small Commercial, Programs, and Bermuda.

•International: Offers specialty insurance products outside of the U.S. and Bermuda, operating in 15 countries across the globe. Products are offered through the London wholesale market, through its Lloyd's of London Syndicate, and through local in-country operations in Canada, Asia Pacific, the United Kingdom (U.K.), and across the European Union (E.U.). Business written through the International division covers worldwide risks, including risks located in the U.S.

•Global Reinsurance: Previously offered casualty and specialty reinsurance products. In August 2025, Markel Insurance sold the renewal rights for contracts written through this division, and the division entered into run-off. The Global Reinsurance division's gross premium volume in 2025 and 2024 was $1.0 billion and $1.2 billion, respectively. As many of the contracts previously written within this division were multi-year agreements, we expect premiums to continue earning over the next two to three years and loss reserves to take several additional years to run off.

10K - 5

Our Markel Insurance segment gross premium volume in 2025 was $12.5 billion, which included $10.6 billion of underwriting premiums and $1.9 billion of fronting premiums. The following chart presents the composition of our Markel Insurance segment by division based on 2025 underwriting gross premium volume.

Through its Bermuda platform, the Programs and Solutions division also fronts business for Nephila Reinsurers (see note 18 of the notes to consolidated financial statements under Item 8). In general, fronting refers to business written on behalf of a general agent or capacity provider that is then ceded to a capacity provider in exchange for ceding fees.

Markel Insurance's underwriting and other insurance-related activities also includes the run-off of the discontinued intellectual property collateral protection insurance product line, life and annuity reinsurance business, and certain asbestos and environmental exposures, none of which is managed through its divisions.

Major Product Lines

The following chart presents the composition of our Markel Insurance segment's ongoing divisions by major product line based on 2025 underwriting gross premium volume. The Global Reinsurance division, which entered into run-off in August 2025, is presented separately from the major product lines for the ongoing divisions. Prior to entering into run-off, the Global Reinsurance division primarily wrote professional liability, general liability, marine and energy, workers compensation, and credit and surety product lines.

General liability	✓	✓	✓
Professional liability	✓	✓	✓
Personal lines		✓
Marine and energy			✓

Specialty Programs		✓
Workers' compensation		✓
Credit and surety		✓	✓

General Liability

Our general liability product offerings include a variety of primary and excess liability coverages for small, middle market, and Fortune 1000 commercial accounts. We insure businesses across most industry classes, including the construction, life sciences, energy, medical, healthcare, pharmaceutical, professional services, social welfare, recreational, transportation, manufacturing, real estate, and hospitality industries. Specific products include primary general liability, excess and umbrella, products liability, and environmental liability.

Professional Liability

Our professional liability product lines provide insurance solutions for small, middle market, and risk-managed accounts with coverage that is tailored to their exposures and needs. Professional liability coverages include errors and omissions for specialized professions, directors and officers for publicly traded, private, and non-profit companies, cyber, employment practices liability, professional indemnity, transaction liability, and union liability. Our cyber insurance offerings help businesses mitigate the financial risks associated with cyberattacks, data breaches, and other digital security incidents.

Personal Lines

We offer personal lines products focused on providing property coverage for homeowners who do not qualify for standard homeowner's coverages, as well as personal umbrella coverage. Additionally, first and third-party coverages are offered in the U.S. for classic cars, motorcycles, and a variety of personal watercraft and recreational vehicles. Beginning on January 1, 2026, our U.S. classic car business, written on behalf of Hagerty, Inc., transitioned from being an underwriting product to a fronting arrangement.

Marine and Energy

We provide marine and energy products including a portfolio of coverages for cargo, energy, hull, liability, war, and terrorism risks worldwide. The cargo product line is an international transit-based book providing coverage for many types of cargo. Energy coverage includes all aspects of oil, gas, and renewable energy activities. Our renewable energy activities include coverages for onshore and offshore wind farms, as well as alternative energy generation and storage technology projects. Hull coverages consist of coverage for physical damage to ocean-going tonnage, yachts, and mortgagees' interests. Liability coverage provides coverage for a broad range of energy liabilities, as well as traditional marine exposures including charterers, terminal operators, and ship repairers. Marine war coverage includes protections for the hulls of ships, and other related interests, against war and associated perils. Terrorism coverage includes coverage for property damage and business interruption related to political and civil violence and war on land.

Property

Our property coverages consist principally of fire, allied lines (including windstorm, hail, and water damage) and other specialized property coverages, including catastrophe-exposed property risks such as earthquake and wind on both a primary and excess basis. Catastrophe-exposed property risks can present higher severity than more standard property risks due to the impacts from earthquakes and severe weather events such as hurricanes, convective storms, and wildfires. Our property coverages are exposed to windstorm losses that, based on the seasonal nature of those events, are more likely to occur in the third and fourth quarters of the year. Our property risks range from small, single-location accounts to large, multi-state, multi-location, multi-national accounts on a worldwide basis. Other types of property products include inland marine products, railroad-related products, and specie coverage for fine art on exhibition and in private collections.

10K - 7

Specialty Programs

Our specialty programs business is offered in the U.S. on a standalone or package basis and generally targets specialized commercial markets and various customer groups, such as amateur sports and fitness clubs. Certain specialty programs use managing general agents with delegated underwriting authorities to offer single source admitted and non-admitted programs for a specific industry, class, or line of business. When we delegate underwriting authority, we implement governance procedures around risk appetite, insurance limits, product and geographic mix, and incorporate our own view on ultimate losses.

Workers' Compensation

We offer workers' compensation products in the U.S. and provide wage replacement and medical benefits to employees injured in the course of employment. We target small commercial, service, and artisan contractor businesses, retail stores, and restaurants.

Credit and Surety

Our credit and surety products consist primarily of trade credit and prepayment coverage and a range of bonds and guarantees that support contractual obligations, contractual performance, and judicial proceedings, as well as other coverages for specific credit risks, such as counterparty insolvency and defaults by government-owned entities.

Competition

The specialty insurance market in which we compete differs significantly from the standard market. In the standard market, regulations dictate relatively uniform products and coverages among competitors resulting in competition primarily on the basis of price. Competition in the specialty insurance market tends to focus less on price and more on other value-based considerations, such as service, distribution, expertise, capacity, product innovation, coverage limits, and financial strength ratings assigned by independent rating agencies. In all of our markets, we compete through our ability to develop specialty products that satisfy well-defined market needs and by maintaining relationships with agents, brokers, and insureds who rely on our expertise. This expertise is our principal means of competing.

Our insurance subsidiaries are assigned financial strength ratings from one or more rating agencies, including A.M. Best Company, Standard & Poor's, and Moody's. Financial stability and strength are important considerations of policyholders, cedents, and insurance agents and brokers. The ratings issued by these agencies are publicly available directly from the agencies. A summary of the ratings issued for our insurance subsidiaries is also available on our website at www.mklgroup.com/financial-strength-rating, however, that information on our website is not incorporated by reference into this report. See the "Financial Strength" risk factors under Item 1A Risk Factors for discussion of risks related to our financial strength ratings.

Our U.S. Wholesale and Specialty division primarily competes with large, global specialty insurance carriers operating in the U.S. E&S market. Within our Programs and Solutions division, competition differs for each business unit based on the particular product offered, as well as the market and distribution channel. The insurance products we offer within our Programs and Solutions division are highly specialized, and we rely on our expertise and product innovation to compete.

Within our International division, competition varies depending on the markets in which we operate. Our London market operations compete globally with London and U.S. based specialty insurance carriers and other Lloyds syndicates. We compete primarily on our underwriting expertise, service, and our ability to place unique risks. Outside of London, we compete locally in the countries in which we operate, facing differentiated local market competition. Our local presence and market expertise allow us to successfully operate in these jurisdictions.

Market conditions, risk tolerance, and capital capacity influence the degree of competition at any point in time. During periods of excess underwriting capacity, as defined by availability of capital, competition can result in lower pricing and less favorable policy terms and conditions for insurers. During periods of reduced underwriting capacity, pricing and policy terms and conditions are generally more favorable for insurers. Historically, the performance of the property and casualty insurance industry has tended to fluctuate in cyclical periods of price competition and excess underwriting capacity, followed by periods of high premium rates and shortages of underwriting capacity. At any given time, our portfolio of insurance products could be experiencing varying combinations of these characteristics.

Markel Insurance offers a diverse portfolio of over 100 individually managed products, each with its own distinct competitive environment, which requires us to be responsive to changes in market conditions for individual product lines. With each of our products, we seek to write business that produces consistent underwriting profits and adequate returns on capital by

10K - 8

maintaining adequate rates for our premium writings in relation to expected loss cost trends. We routinely review the pricing for all of our product lines. When we believe the prevailing market price will not support our underwriting profit targets, the business is not written. As a result of our underwriting discipline, gross premium volume may vary when we alter our product offerings to maintain or improve underwriting profitability. For example, we stopped writing risk-managed directors and officers business from our European platform in late 2024 and our U.S. platform in early 2025 following heightened loss performance, consolidating all of our risk-managed professional liability offerings within our Bermuda platform.

Markets and Distribution

The following chart presents the composition of the 2025 underwriting gross premium volume for the Markel Insurance segment by regulatory market channel. The Global Reinsurance division, which entered into run-off in August 2025, is presented separately.

U.S. Admitted

Our U.S. business written in the admitted market focuses on unique and hard-to-place risks that must remain with an admitted insurance company for marketing and regulatory reasons. Hard-to-place risks written in the admitted market cover insureds engaged in highly specialized activities that require a total insurance program not otherwise available from standard insurers. The admitted market is subject to more state regulation than the E&S market, particularly with regard to rate and form filing requirements, premium tax payment requirements, and membership in various state associations. We write business in the U.S. using multiple insurance carriers that collectively are licensed, authorized, or accredited in all 50 states and the District of Columbia.

Business written in the admitted market is placed primarily by retail insurance agents and brokers, as well as managing general agents. Managing general agents have broader underwriting authority than retail agents and brokers. The managing general agents we utilize are carefully selected based on a track record of proficiency with their selected products, and the business written is controlled through regular audits and pre-approvals. In addition, we market certain products and programs written on an admitted basis directly to consumers.

U.S. Excess and Surplus

The E&S, or non-admitted, market focuses on hard-to-place risks and loss exposures that generally are not written in the standard market. E&S eligibility allows us to underwrite unique loss exposures with more flexible policy forms and premium rates. The E&S market is accessed primarily through wholesale insurance brokers, which have limited quoting and binding authority. Our E&S business is written on Evanston Insurance Company, an Illinois domiciled E&S carrier licensed to do business in all 50 states and the District of Columbia.

In 2024, the E&S market represented $129.8 billion, or 12%, of the $1.1 trillion U.S. property and casualty industry.1 In 2024, we were the fifth largest E&S writer in the U.S. as measured by direct premium writings.1 Overall, the U.S. E&S markets we serve are experiencing robust growth driven by long-term secular trends. We believe the increasing need for tailored solutions in a more complex risk environment will continue to provide significant tailwinds for the E&S market.

London Wholesale

We also participate in the London wholesale market, which is a global market known for its ability to provide innovative, tailored coverage, and capacity for unique and hard-to-place risks worldwide, including in the U.S. Many of these risks have significantly higher limits than those placed through the standard market. Insurance brokers place most of the business in the London wholesale market. Risks written in this market are written on either a direct or a subscription basis, the latter of which means that loss exposures are typically insured by more than one insurance company or syndicate, often due to the high limits of insurance coverage required. We participate in the London wholesale market primarily through Markel Capital Limited (Markel Capital) and Markel International Insurance Company Limited (MIICL). Markel Capital is the corporate capital provider for Markel Syndicate 3000 (Syndicate 3000), which is our platform to write business globally through Lloyds of London.

International non-London

Outside of London, we have been growing in the E.U., the U.K., Canada, and Asia Pacific. Our strategy for geographic and product expansion within these markets reflects our overall strategy of empowering local leaders who have extensive knowledge of those markets and products. We utilize Syndicate 3000, MIICL, and Markel Insurance SE (MISE), a regulated insurance carrier located in Munich, Germany, to enable these writings. From its offices in Germany, MISE transacts business in E.U. member states and throughout the European Economic Area. MISE has established branches in Ireland, the Netherlands, Spain, Switzerland, France, and the U.K. Syndicate 3000 and MIICL supplement, or serve as an alternative to, MISE for access to the E.U. markets and within Canada and Asia Pacific.

Bermuda

In Bermuda, we participate in the worldwide insurance market. The Bermuda property and casualty market is a significant source of capital for the U.S. market. Business written in the Bermuda market is typically placed by a Bermuda-based wholesale broker. We conduct our Bermuda underwriting operations through Markel Bermuda Limited, which is registered as a Class 4 insurer and Class C long-term insurer under the insurance laws of Bermuda.

Global Reinsurance

The Global Reinsurance division, which was placed into run-off in 2025, conducted its operations primarily through Markel Global Reinsurance Company.

Market and Distribution Concentrations

While we operate in various other markets, substantially all of our gross written premiums in 2025 were written from our platforms in the United States, the United Kingdom, Bermuda, and Germany. In 2025, 73% of gross premium writings from our global underwriting operations were attributed to risks or cedents located in the United States.

A significant volume of premium for the property and casualty insurance industry is produced through a small number of large insurance brokers. In 2025, the top five independent brokers accounted for 37% of our underwriting gross premiums written.

Investments

Invested assets held by Markel Insurance are derived from policyholder and shareholder capital. Policyholder capital, or float, represents net policyholder funds held for investment, which are a direct result of our underwriting activities and the time lag between our receipt of premiums and payment of losses and expenses. Shareholder capital is used to support the regulatory capital requirements of our insurance entities, both to support future premium writings and manage short-term stress scenarios.

Markel Insurance's investment portfolio is managed by Markel Group's CEO and a small team of investment professionals at Markel Group. Investments are primarily comprised of fixed maturity securities and publicly traded equity securities, as well as short-term investments and cash.

Shareholder capital is available for investment in equity securities. When making investments in equity securities, we follow our four key investment principles previously discussed. Markel Insurance's investment portfolio includes a greater proportion of equity securities than is typical within the insurance industry. Over longer time periods, equity securities have produced higher returns than fixed maturity securities. By holding shareholder capital in equity securities, rather than fixed maturity securities, we are required to hold more capital within our regulated insurance subsidiaries to meet capital requirements due to the short-term volatility inherent in the public equity markets. Over the long term, this approach has produced, and we believe will continue to produce, higher overall returns on equity.

10K - 10

Policyholder capital is invested predominantly in high-quality government and municipal bonds and mortgage-backed securities that generally match the duration and currency of our loss reserves with the goal of protecting principal to ensure we are able to pay claims. We typically hold these investments until maturity. As a result, unrealized holding gains and losses on these securities attributable to changes in interest rates are generally expected to reverse as the securities mature. Policyholder capital is also held in short-term investments and cash and cash equivalents to provide short-term liquidity for projected claims payments, reinsurance costs, and operating expenses.

State National's capacity providers include domestic and foreign insurers and institutional risk investors that want to access specific lines of U.S. property and casualty insurance business but may not have the required licenses, filings, or financial strength ratings to do so.

Through its programs services operations, State National writes a wide variety of insurance and reinsurance products, principally including general liability, commercial liability, commercial multi-peril, property, and workers' compensation.

State National's contracts with capacity providers do not legally discharge it from the primary liability for the full amount of the policies, therefore, State National is exposed to the credit risk of its capacity providers.

State National's lender services operations write collateral protection insurance on a risk-bearing basis for automobiles and other vehicles held as collateral for loans made by credit unions, banks, and specialty finance companies.

Corporate

Our corporate operations encompass holding company activities, which are performed by a small team of associates that support our businesses and leaders in certain key areas: significant capital decisions, cultural stewardship, leadership support and decisions, and performing the responsibilities consistent with sound governance and required of a public company.

10K - 13

Capital held at the holding company, which is primarily comprised of equity securities, short-term investments, and cash and cash equivalents, comes from returns provided by our businesses and investments over time. We also supplement these cash flow streams with external financing. Capital held at the holding company is used to service our senior debt, fulfill other corporate obligations, and serve as additional capital to support our businesses or allocate to future investment opportunities.

Historically, corporate expenses were fully allocated to our segment results. Beginning in the third quarter of 2025, we discontinued allocating corporate expenses that are not integral to operating the underlying businesses. This change provides investors with greater transparency into both the operating performance of our businesses and the expenses incurred by the holding company to manage and support the entire Markel Group system.

Regulatory Environment

We are subject to extensive U.S. state and federal, as well as international, regulation and supervision in the jurisdictions in which we do business. Regulations vary from jurisdiction to jurisdiction. Additionally, as a company with publicly traded securities, we are also subject to certain legal and regulatory requirements applicable generally to public companies, including the rules and regulations of the U.S. Securities and Exchange Commission (SEC) and the listing standards of the New York Stock Exchange relating to reporting and disclosure, accounting and financial reporting, corporate governance and other matters.

The following is a summary of the regulatory environment for our operating businesses, but it is not intended to be a comprehensive review of every regulation to which we are subject. For information regarding certain risks associated with regulations applicable to our businesses, see Item 1A Risk Factors.

The insurance regulation sections below primarily relate to Markel Insurance and State National.

Group Insurance Regulation and Supervision

Group Supervision - Global Supervisory College; Global Common Framework. Regulators within and outside the U.S. are increasingly coordinating the regulation of multinational insurers by conducting supervisory colleges. A supervisory college is a forum of the regulators having jurisdictional authority over an insurance holding company's worldwide insurance subsidiaries. The supervisory college meets with executive management to evaluate the insurance group on both a group-wide and legal-entity basis, particularly with respect to its financial data, business strategies, enterprise risk management and corporate governance. The Illinois Department of Insurance is our global lead insurance regulator for purposes of conducting our supervisory college.

The International Association of Insurance Supervisors has adopted the Common Framework for the Supervision of Internationally Active Insurance Groups (ComFrame). ComFrame establishes a comprehensive framework for supervisors to address group-wide activities and risks of internationally active insurance groups (IAIGs) and lays the groundwork for better supervisory cooperation and coordination. In 2023, it was determined that we met the criteria to be identified as an IAIG. ComFrame requires the designation of a group-wide supervisor (regulator) for each IAIG and imposes a group capital requirement that will be applied to an IAIG in addition to legal entity capital requirements imposed by state and international insurance regulators. The Illinois Department of Insurance has been designated as our group-wide supervisor.

Holding Company Statutes. We also are subject to state statutes governing insurance holding company systems, which typically require that we periodically file information with the appropriate state insurance commissioner, including information concerning our capital structure, ownership, financial condition, dividend payments and other material transactions with affiliates, and general business operations. These statutes also require approval of changes in control of an insurer or an insurance holding company. Generally, "control" for these purposes is defined as ownership or voting power of 10% or more of a company's voting shares. We must submit annually to our lead insurance regulator an:

•Own Risk and Solvency Assessment Summary Report (ORSA), which is a confidential internal assessment of the material and relevant risks associated with an insurer's current business plan and the sufficiency of capital resources to support those risks; and

•Annual enterprise risk report, which must identify the material risks within the insurance holding company system that could pose enterprise risk to our U.S. insurance subsidiaries.

U.S. Insurance Regulation

State Regulation

Our U.S. insurance company subsidiaries are subject to varying degrees of regulation and supervision by the states and other jurisdictions in which they do business. In the U.S., authority for the regulation, supervision and administration of the business of insurance in each state is generally delegated to a state insurance commissioner who oversees a regulatory body responsible for the supervision of the business of insurance. State regulatory authorities have broad regulatory, supervisory, and administrative powers over our U.S.-domiciled insurance companies, including related to capital requirements, investment composition, claims handling and adjudication, and market conduct and pricing practices, among other things.

State regulatory authorities generally enforce these provisions through periodic financial and market conduct examinations. Our next scheduled financial exam, covering the period from January 1, 2020 through December 31, 2025, has commenced.

The National Association of Insurance Commissioners (NAIC), comprised of the insurance commissioners of each U.S. jurisdiction, develops or amends model laws and regulations. States are required to adopt certain NAIC model laws and regulations, but have discretion whether, or how, to adopt others, which leads to inconsistent adoption across states.

Federal Regulation

The U.S. federal government generally does not directly regulate the business of insurance. However, two federal government bodies, the Federal Insurance Office (FIO) and the Financial Stability Oversight Council (FSOC) may impact the regulation of insurance. Although the FIO is prohibited from directly regulating the business of insurance, it has authority to represent the U.S. in international insurance matters and has limited powers to preempt certain types of state insurance laws. The FIO also can recommend to the FSOC that it designate an insurer as an entity posing risks to U.S. financial stability in the event of the insurer's material financial distress or failure. We have not been so designated.

The U.S. federal laws that most affect our day-to-day operations are: the Gramm-Leach-Bliley Act; the Fair Credit Reporting Act; the Health Insurance Portability and Accountability Act of 1996; the Terrorism Risk Insurance Act of 2002; the Nonadmitted and Reinsurance Reform Act of 2010; the Foreign Corrupt Practices Act, and the rules and regulations of the Office of Foreign Assets Control.

International Insurance Regulation

Overview. Our international insurance companies are domiciled in the U.K., Germany, and Bermuda and are subject to regulation in those jurisdictions. Those regulations, which vary depending on the jurisdiction, include, among others:

•solvency and market conduct regulations;

•anti-corruption, anti-money laundering, and anti-terrorism financing guidelines, laws, and regulations;

•privacy, insurance, tax, tariff, economic, and trade sanctions laws and regulations; and

•corporate, competition, employment, intellectual property, and investment laws and regulations.

In addition, we conduct business in Canada and Asia Pacific, where our businesses also are supervised by local regulatory authorities.

U.K. and European Regulation. We are subject to regulation by the Prudential Regulatory Authority and Financial Conduct Authority in respect of our U.K. insurance companies. We are also subject to regulation by the Federal Financial Supervisory Authority, better known by its abbreviation BaFin, in respect of our German insurance company.

The E.U.'s General Data Protection Regulation (GDPR) requires businesses operating in the European Economic Area (E.E.A.), and businesses transacting with E.E.A. citizens, to comply with conditions for processing personal data. Following the U.K.'s exit from the E.U., GDPR was transposed into U.K. law. The E.U. has granted adequacy status to the U.K.'s data protection laws, valid until December 2031 with the possibility of renewal, meaning that they are deemed essentially equivalent to E.U. data protection laws, such that data can continue to flow as it did when the U.K. was part of the E.U.

10K - 15

Solvency II Directive (Solvency II) requires our German insurance company to maintain certain capital standards and publish risk-related information in the form of a Solvency and Financial Condition Report. Following the U.K.'s exit from the E.U., Solvency II was transposed into U.K. law as retained law applying to our U.K. insurance businesses. The U.K. government, under the Financial Services and Markets Act 2023, has opted to repeal certain portions of retained E.U. law. This repeal will occur in stages and, where necessary, after replacement regulations designed for the U.K. are in place. The Prudential Regulation Authority has published reforms to the Solvency II retained law, known as Solvency UK, which took effect December 31, 2024.

Bermuda Regulation. The insurance industry in Bermuda, including our Bermuda-domiciled insurance company, is regulated by the Bermuda Monetary Authority (BMA). Under the Bermuda Insurance Act 1978, and related regulations and standards of the BMA, each Bermuda insurance company is subject to, among other things:

•licensing, solvency, and liquidity requirements;

•periodic examinations of the company and its financial condition; and

•requirements to maintain a principal office and principal representative in Bermuda.

ILS Regulation

Our Nephila insurance-linked securities operations are subject to regulation and supervision by various regulatory authorities, both in the U.S. and internationally. Certain of our Nephila subsidiaries are organized and regulated as follows:

•registered with the SEC as an investment adviser under the Investment Advisers Act of 1940;

•registered with the U.S. Commodity Futures Trading Commission as a commodity pool operator or a commodity trading advisor under the Commodity Exchange Act; and

•registered with the BMA as an insurance manager under the Bermuda Insurance Act 1978.

Certain Nephila subsidiaries serve as the investment manager to one or more private funds that are registered with the BMA under the Investment Funds Act 2006, or the Segregated Accounts Companies Act 2000. In addition, these operations include business relationships with certain U.S., U.K., and Bermuda insurance companies that are subject to U.S. and international insurance regulation as previously described in this "Regulatory Environment" section.

As a result, subsidiaries involved in our Nephila insurance-linked securities operations are subject to regulations that may impose substantive and material restrictions and requirements on their operations, including, among other things, a fiduciary duty to act in the best interests of their clients; disclosure of information about our businesses and conflicts of interest to clients; and other restrictions and requirements applicable to custody of client assets.

Regulation of Other Operating Businesses

Our other operating businesses are subject to a wide variety of U.S. federal, state, and local laws and regulations, as well as international laws and regulations applicable to their international operations. The most significant of these laws and regulations cover the following areas: safety, health, employment, the environment, transportation, U.S. and international trade, anti-corruption, data privacy and security and government contracts.

Regulations Regarding Disclosure or Management of Climate-Related Risks and Disclosure of Greenhouse Gas Emissions

A variety of U.S. federal and state and international governments and regulators have adopted or are in the process of adopting requirements for the disclosure of climate-related risks and greenhouse gas emissions to which Markel Group and certain of our subsidiaries are or may be subject in the future. For example, certain of our insurance companies are required to report their climate-related risks and greenhouse gas emissions. In addition, in some cases regulated insurers are expected to integrate financial risks related to climate change into their governance frameworks, risk management processes, business strategies and scenario analysis, and develop their approach to climate-related financial disclosure.

Human Capital

At Markel Group, we seek to cultivate an atmosphere in which our associates can reach their full potential while contributing to the success of Markel Group. The Markel Style, our creedal statement written in 1986 in preparation for our initial public offering, memorialized how we seek to operate our businesses and treat one another.

Markel Group consists of independently operated businesses across a range of industries. The leader of each of our businesses is empowered to direct the strategy and day-to-day operations of their respective companies, including human capital matters. Our business leaders are expected to conduct business and foster a culture that reflects the principles of The Markel Style.

When adding businesses to Markel Group, we seek, among other things, leaders who demonstrate equal parts talent and integrity. These qualities are core to our strategy to empower our leaders to serve their customers and run their businesses with a high degree of autonomy while being held accountable to the broader company and its key stakeholders. We believe this management approach is unique and attracts culturally-aligned, high-performing leaders and businesses, while differentiating us against other acquisitive business groups.

At December 31, 2025, Markel Group and its family of businesses employed approximately 22,900 associates.

Item 1A. RISK FACTORS

A wide range of factors could materially affect our future prospects and performance. The matters addressed in Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations, including under "Safe Harbor and Cautionary Statement" and "Critical Accounting Estimates", and Item 7A Quantitative and Qualitative Disclosures About Market Risk, as well as other information included or incorporated in this report, describe many of the significant risks that could affect our businesses, results of operations and financial condition. We are also subject to the risks discussed below.

One or more of the risks discussed in this Item 1A. Risk Factors, and others we cannot anticipate, could have material adverse effects on our results of operations and financial condition; and the extent of these effects will depend, at least in part, on the scope, severity, frequency, or duration of the specific event or circumstance. In addition, we may take steps to prevent, mitigate or manage potential risks or liabilities, and related developments, and some of those steps may have a material adverse effect on our results of operations and financial condition. Even if an unfavorable outcome does not materialize, these factors, and actions we may take in response, may have a material adverse impact on our reputation or result in substantial expense and disruption.

Headings and sub-headings for the Risk Factors below are for reference purposes only and are not intended to limit or affect in any way the meaning or scope of each Risk Factor.

Risks Primarily Related to Our Holding Company and Operating Structure

Our businesses operate through independent local management teams, which could result in inconsistent management, governance, and oversight practices. Our businesses operate on a decentralized basis through independent local management teams, which could result in inconsistent management, governance, and oversight practices. Our businesses operate in the United States (U.S.), the United Kingdom (U.K.), Bermuda, the E.U., Canada, and Asia Pacific. Our Markel Group senior management team oversees our businesses; however, independent local management teams are responsible for strategy, day-to-day operations, profitability, personnel decisions, the growth of the business, and legal and regulatory compliance, including adherence to applicable laws. Operating through subsidiary-level management teams can make it difficult for us to implement coordinated procedures throughout our global businesses. In addition, some of our businesses operate with management, sales, and support personnel that may be insufficient to support growth in their respective locations and industries. We continue to enhance our oversight procedures; however, our operating strategy nonetheless could result in inconsistent management, governance, and oversight practices, which may have a material adverse effect on our results of operations and financial condition.

Investments

We invest a significant portion of our shareholders' equity in equity securities and our equity portfolio is concentrated, which may result in significant variability in our results and net income and may have a material adverse effect on shareholders' equity and on our ability to carry out our business plans. Equity securities were 70% of our shareholders' equity at December 31, 2025. Equity securities have historically produced higher returns than fixed maturity securities over

10K - 17

long periods of time; however, investing in equity securities may result in significant variability in our results from one period to the next. In volatile financial markets, we could experience significant declines in the fair value of our equity securities, which would result in a material decrease in net income and shareholders' equity. Our portfolio of equity securities is concentrated in particular issuers and industries and, as a result, a decline in the fair value of these concentrated investments also could result in a material decrease in net income and shareholders' equity. A material decrease in shareholders' equity may have a material adverse effect on our ability to carry out our business plans. See also, "We invest a significant portion of the capital required to be held at our insurance companies in equity securities."

Acquisitions, Integration, and Reliance on Management and Personnel

The integration of acquired businesses may not be as successful as we anticipate. The integration of acquired businesses may not be as successful as we anticipate. We have completed, and expect to complete, acquisitions in an effort to achieve profitable growth and to create additional value on a diversified basis. Acquisitions present operational, regulatory, strategic, and financial risks, as well as risks associated with liabilities arising from the previous operations of the acquired businesses. We also must make decisions about the degree to which we integrate acquisitions into our existing businesses, operations, and systems, and over what timeframe. Those decisions may adversely affect how successfully the acquired businesses perform, both in the short term and in the long term. All of these risks are magnified in the case of a large acquisition. Integration of the operations, systems, and personnel of acquired businesses may prove more difficult than anticipated, which may result in failure to achieve financial objectives associated with the acquisition or diversion of management attention and other resources. In addition, integration of formerly privately held companies into the management and internal control and financial reporting systems of a publicly held company presents additional risks. See note 3 of the notes to consolidated financial statements included under Item 8 for information about our recent acquisitions.

Impairment in the value of our goodwill or intangible assets could have a material adverse effect on our operating results and financial condition. As of December 31, 2025, goodwill and intangible assets totaled $4.4 billion and represented 23% of shareholders' equity. We record goodwill and intangible assets at fair value upon the acquisition of a business. Goodwill represents the excess of amounts paid to acquire businesses over the fair value of the net assets acquired. Goodwill and indefinite-lived intangible assets are evaluated for impairment annually, or more frequently if events or circumstances indicate that their carrying value may not be recoverable. Developments that adversely affect the future cash flows or earnings of an acquired business, including declining growth in industry segments or sustained market declines, loss of required licenses, permits, or government designations, as well as increases in cost of capital and other factors that impact the fair value of a reporting unit, could result in an impairment of goodwill or intangible assets and, in turn, a charge to net income. Such a charge could have a material adverse effect on our results of operations or financial condition. See "Critical Accounting Estimates - Goodwill and Intangible Assets" included under Item 7 Management's Discussion and Analysis of Financial Condition and Results of Operations and note 8 of the notes to consolidated financial statements included under Item 8 for information about our goodwill and intangible assets.

The loss of, or failure to successfully implement succession planning for, one or more key executives or an inability to attract and retain qualified personnel in our various businesses could have a material adverse effect on us. Our success depends on our ability to retain the services of our existing key executives, implement successful succession planning, and attract and retain additional qualified personnel in the future. The temporary or permanent loss of the services of any of our key executives or the inability to hire and retain other highly qualified personnel in the future could have a material adverse effect on our ability to conduct or grow our business.

Additionally, in our decentralized business model, we rely on qualified personnel to manage and operate our various businesses. We need qualified and competent management to direct day-to-day business activities of our operating subsidiaries and to manage changes in future business operations due to changing business or regulatory environments. Our operating subsidiaries also need qualified and competent personnel to execute business plans and serve their customers, suppliers, and other stakeholders. Our inability to recruit, train and retain qualified and competent managers and personnel could negatively affect the operating results, financial condition, and liquidity of our subsidiaries and Markel Group as a whole.

Liquidity and Access to Capital

Our liquidity and our ability to meet our debt and other obligations depend on the receipt of funds from our subsidiaries. We are a holding company, and as a result, our cash flow and our ability to meet our debt and other obligations depend upon the earnings of our subsidiaries and on the distribution of earnings or other payments by our subsidiaries to us. The payment of dividends by our insurance subsidiaries, which accounts for a significant portion of our holding company operating cash flows, may require prior regulatory notice or approval or may be restricted by capital requirements imposed by

10K - 18

regulatory authorities. Similarly, our insurance subsidiaries may require capital contributions from us to satisfy their capital requirements, particularly during periods when their capital declines due to significant declines in the fair value of the equity securities they hold.

We may require additional capital in the future, which may not be available or may only be available on unfavorable terms. To the extent that cash flows generated by our businesses and investments are insufficient to fund future operating requirements, we may need to raise additional funds through financing or curtail our growth. We also may be required to liquidate fixed maturity securities or equity securities, which may result in realized investment losses. Any further sources of capital, including capacity needed for letters of credit, if available at all, may be on terms that are unfavorable to us. Our access to additional sources of capital will depend on a variety of factors, such as market conditions, the general availability of credit, the availability of credit to the industries in which we operate, our results of operations, financial condition, credit ratings, and credit capacity, as well as pending litigation or regulatory investigations. Our ability to borrow under our revolving credit facility and letter of credit facilities is contingent on our compliance with the covenants and other requirements under those facilities. Similarly, our access to capital may be impaired if regulatory authorities or rating agencies take negative actions against us. Our inability to obtain adequate capital when needed could have a negative impact on our ability to invest in, or take advantage of opportunities to expand, our businesses, such as possible acquisitions or the creation of new ventures, and inhibit our ability to refinance our existing indebtedness on terms acceptable to us. Any of these effects could have a material adverse effect on our results of operations and financial condition.

A failure to comply with covenants and other requirements under our credit facilities, senior debt, and other indebtedness could have a material adverse effect on us. The agreements and indentures relating to our credit facilities, senior debt, and other indebtedness, including letter of credit facilities used by certain of our subsidiaries, contain covenants and other requirements. If we fail to comply with those covenants or requirements, the lenders, noteholders, or counterparties under those agreements and indentures could declare a default and demand immediate repayment of all amounts owed to them. In addition, where applicable, our lenders may cancel their commitments to lend or issue letters of credit or require us to pledge additional or a different type of collateral. A default under one debt agreement may also put us at risk of a cross-default under other debt agreements or other arrangements. Any of these effects could have a material adverse effect on our results of operations and financial condition.

Our senior debt is rated by various rating agencies, and a downgrade or potential downgrade in one or more of these ratings could have a material adverse effect on us. Our senior debt securities are rated by various rating agencies. Our senior debt ratings affect the availability and cost of capital. Our debt ratings are subject to periodic review, and are subject to revision or withdrawal at any time. We cannot be sure that we will be able to retain our current, or any future, ratings. A ratings downgrade could have a material adverse effect on our liquidity, including the availability of our letter of credit facilities, limit our access to capital markets, and increase our cost of borrowing or issuing debt.

Shareholder Activism

Our business could be disrupted as a result of a threatened proxy contest or other actions of activist shareholders. Publicly traded companies have increasingly become subject to campaigns by investors advocating corporate actions such as operational and financial restructuring, increased borrowing, special dividends, share repurchases, or sales of assets or the entire company. While we value constructive feedback from our investors and regularly engage in dialogue with them on various matters, we have in the past and may in the future be subject to actions or proposals from activist shareholders that may not align with our business strategies or the interests of our other shareholders. Responding to actions by such activist shareholders or others could be costly and time consuming, disrupt our operations, and divert the attention of our Board of Directors and senior management team from the pursuit of business strategies, which could adversely affect our business, financial condition, and results of operations. In addition, actual or perceived uncertainties as to our future direction caused by activist activities may cause or appear to cause instability, potentially making it more difficult to attract and retain qualified personnel and identify and secure investment opportunities. Activist shareholder activities may also cause significant fluctuations in our share price based on temporary or speculative market perceptions, or other factors that do not necessarily reflect the fundamental underlying value of our businesses.

Loss Exposures

We may experience losses or disruptions from catastrophes and other significant, infrequent loss events. As a company with significant property and casualty insurance underwriting operations, we may experience losses from man-made or natural

10K - 19

catastrophes. Catastrophes and other significant, infrequent loss events include, but are not limited to, windstorms, hurricanes, earthquakes, tornadoes, derechos, hail, severe winter weather, floods, and wildfires and may include pandemics and events related to terrorism, broad reaching cyberattacks, riots, and political and civil unrest. While we employ catastrophe modeling tools in our underwriting process, we cannot predict how severe a potential catastrophe will be before it occurs. The extent of losses from catastrophes is a function of the total amount of losses incurred, the number of insureds affected, the frequency and severity of the events, the effectiveness of our catastrophe risk management program, and the adequacy of our reinsurance coverage. Catastrophes can occur over numerous geographic areas; however, some catastrophes may produce significant damage in large, heavily populated areas. We offer 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. Catastrophes also may result in significant disruptions in our insurance and other operations, as well as loss of income and assets. The impacts of climate change may increase the frequency and/or severity of weather-related catastrophes, which may result in elevated catastrophe-related losses or disruptions, which may be material. See "Climate Change" for more information about the potential impacts of climate change.

The failure of any of the methods we employ to manage our loss exposures could have a material adverse effect on us. We seek to manage our loss exposures in a variety of ways, including adhering to maximum limitations on policies written in defined geographical zones, implementing maximum gross limits by coverage for each insured, establishing per risk and per occurrence limitations for each event, employing coverage restrictions, and following prudent underwriting guidelines for each program written. We also seek to manage our loss exposures through geographic and industry diversification. Underwriting is a matter of judgment, involving assumptions about matters that are inherently unpredictable and beyond our control, and for which historical experience and probability analysis may not provide sufficient guidance. For example, as weather patterns evolve, historical data and models may be less predictive, increasing the uncertainty in catastrophe loss estimates and pricing. One or more future events could result in claims that substantially exceed our expectations, which could have a material adverse effect on our results of operations and financial condition. In addition, we seek to manage our loss exposures through policy terms, coverage exclusions, and choice of legal forum. Disputes relating to coverage and choice of legal forum also arise. As a result, various provisions of our policies, such as choice of forum, or coverage limitations or exclusions, may not be enforceable in the manner we intend and some or all of our methods to manage loss exposures may prove ineffective.

The effects of emerging claim and coverage issues on our business are uncertain. As industry practices and legal, judicial, social, and other environmental conditions change, unexpected and unintended issues related to claims and coverage may emerge. These issues could have a material adverse effect on our results of operations or financial condition by either broadening coverage beyond our underwriting intent or increasing the frequency and/or severity of claims. For example, rising costs, litigation funding, social inflation, including new or expanded theories of liability, higher adverse verdicts, and legislative changes, such as extended statutes of limitations, may result in higher and more frequent claims over a longer reporting period than originally expected. In some instances, these changes may not become apparent until after we have issued insurance or reinsurance contracts that are affected by the changes. As a result, the full extent of liability under our insurance or reinsurance contracts may not be known for many years after a contract is issued.

We use analytical models to assist our decision making in key areas such as pricing, reserving, and capital modeling, and actual results may differ materially from the model outputs and related analyses. We use various modeling techniques and data analytics (e.g., scenarios, predictive and stochastic modeling, and forecasting) to analyze and estimate exposures, loss trends, and other risks associated with our insurance businesses. This includes both proprietary and third-party modeled outputs and related analyses to assist us in, among other things, decision-making related to underwriting, pricing, capital allocation, reserving, investing, reinsurance, and catastrophe risk. We incorporate numerous assumptions and forecasts about the future level and variability of policyholder behavior, loss frequency and severity, interest rates, equity markets, inflation, capital requirements, and currency exchange rates, among others. The modeled outputs and related analyses from both proprietary models and third-party models, including statistical, artificial intelligence, and machine-learning models, are subject to various assumptions, uncertainties, model design errors (e.g., bias and inadequate validation or documentation), complexities, and the inherent limitations of any statistical analysis, including those arising from the use of historical internal and industry data and assumptions, which could result in mispricing, misreserving, or capital misallocation.

In addition, the modeled outputs and related analyses may from time to time contain inaccuracies, perhaps in material respects, including as a result of inaccurate inputs or applications thereof (whether due to data error, human error, or otherwise). Consequently, actual results may differ materially from our modeled results. Our profitability and financial condition substantially depend on the extent to which our actual experience is consistent with assumptions we use in our models and ultimate model outputs. If, based upon these models or other factors, we misprice our products or fail to appropriately estimate the risks we are exposed to, our business, results of operations, and financial condition may be materially adversely affected.

Loss Reserves

Our results may be affected because actual insured or reinsured losses differ from our loss reserves. Significant periods of time often elapse between the occurrence of an insured or reinsured loss, the reporting of the loss to us, and our payment of that loss. To recognize liabilities for unpaid losses, we establish reserves as balance sheet liabilities representing estimates of amounts needed to pay reported and unreported losses and the related loss adjustment expenses. The process of estimating loss reserves is a difficult and complex exercise involving analytical models with many variables and subjective judgments. This process may also become more difficult if we experience a period of rising inflation, as we experienced in recent years.

As part of the reserving process, we review historical data and consider the impact of various factors, such as:

•trends in claim frequency and severity;

•changes in operations;

•changes to mix of business, terms and conditions, limits and layers;

•emerging economic and social trends;

•trends in insurance rates;

•inflation or deflation; and

•changes in the regulatory and litigation environments.

This process assumes that past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting future events. There is no precise method, however, for evaluating the impact of any specific factor on the adequacy of reserves, and actual results will differ from original estimates. As part of the reserving process, we regularly review our loss reserves and make adjustments as necessary. Future increases in loss reserves for our underwriting operations will, and for our programs services operations may, result in additional charges to earnings, which may be material.

In addition, as discussed above, we use analytical models to assist our decision making in loss reserving, and actual results may differ materially from the model outputs and related analyses.

There is generally greater uncertainty in estimating reserves for long-tail coverages, such as general liability, professional liability, and workers' compensation, as they require a longer period of time for claims to be reported and settled. The impact of changes in economic and social inflation and medical costs are also more pronounced for long-tail coverages due to the longer settlement period. In addition, reinsurance reserves are subject to greater uncertainty than insurance reserves primarily because a reinsurer relies on the original underwriting decisions and claims decisions made by ceding companies and information and data from ceding companies. As a result, we are subject to the risk that our ceding companies may not have adequately evaluated the risks reinsured by us and the premiums ceded may not adequately compensate us for the risks we assume. In addition, reinsurance reserves may be less reliable than insurance reserves because there is generally a longer lapse of time from the occurrence of the event to the reporting of the loss or benefit to the reinsurer and ultimate resolution or settlement of the loss. While we sold the renewal rights for business written by the Markel Insurance Global Reinsurance division in 2025 and the division entered into run-off, we expect reinsurance premiums to continue earning over the next two to three years and loss reserves are expected to take several additional years to run off. Reserves for contracts for which we are not the primary insurer, and participate only in excess layers of loss, are also subject to greater uncertainty than insurance reserves for contracts for which we are the primary insurer for many of the same reasons as reinsurance reserves.

Changes in the assumptions and estimates used in establishing reserves for our life and annuity reinsurance book could result in material increases in our estimated loss reserves for such business. Our run-off life and annuity reinsurance book exposes us to mortality risk, which is the risk that the level of death claims may differ from that which we assumed in establishing the reserves for our life and annuity reinsurance contracts. Some of our life and annuity reinsurance contracts expose us to longevity risk, which is the risk that an insured person will live longer than expected when the reserves were established, or morbidity risk, which is the risk that an insured person will become critically ill or disabled. Our reserving process for the life and annuity reinsurance book is designed with the objective of establishing appropriate reserves for the risks we assumed. Among other things, this process relies heavily on analysis of mortality, longevity, and morbidity trends, lapse rates, interest rates, and expenses. As of December 31, 2025, our reserves for life and annuity benefits totaled $581.6 million.

We expect mortality, morbidity, longevity, and lapse experience to fluctuate somewhat from period to period, but believe they should remain reasonably predictable over a period of many years. Mortality, longevity, morbidity, or lapse experience that is less favorable than the mortality, longevity, morbidity, or lapse rates that we used in establishing the reserves for a reinsurance

10K - 21

agreement will negatively affect our net income because the reserves we originally set for the risks we assumed may not be sufficient to cover the future claims and expense payments. Furthermore, even if the total benefits paid over the life of the contract do not exceed the expected amount, unexpected increases in the incidence of deaths or illness can result in changes to our assumptions in a given reporting period, adversely affecting our net income in any particular reporting period. If there are adverse changes to any of the above factors, a charge to earnings may be recorded, which may have a material adverse effect on our results of operations and financial condition.

Ceded Reinsurance

We may be unable to purchase reinsurance protection on terms acceptable to us, or we may be unable to collect on loss recoveries from reinsurers. Within our underwriting operations, we purchase reinsurance to manage our net retention on individual risks and mitigate the volatility of losses on our results of operations and financial condition, while providing us with the ability to offer policies with sufficient limits to meet policyholder needs. In addition, we reinsure substantially all of the risks inherent in our fronting operations, however, 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. See note 12 of the notes to consolidated financial statements included under Item 8 for information about ceded reinsurance for our fronting operations.

The ceding of insurance does not legally discharge us from our primary liability for the full amount of the policies. Reinsurance recoverables create credit risk as a result of the reinsurer's potential inability or unwillingness to pay reinsurance claims when due. We generally select well capitalized and highly rated reinsurers for our reinsurance purchases and in certain instances we require reinsurers to post substantial collateral to secure the reinsured risks. Deterioration in the credit quality of existing reinsurers or disputes over the terms of reinsurance could result in charges to earnings, which may have a material adverse effect on our results of operations and financial condition. In addition, collateral may not be sufficient to cover the reinsurer's obligation to us, and we may not be able to cause the reinsurer to deliver additional collateral.

As of December 31, 2025, we were the beneficiary of letters of credit, trust accounts, and funds withheld in the aggregate amount of $7.1 billion, collateralizing $14.6 billion in reinsurance recoverables. The remaining unsecured reinsurance recoverables are ceded to highly rated, well capitalized reinsurers. Our reinsurance recoverables are based on estimates, and our actual liabilities may exceed the amount we are able to recover from our reinsurers or any collateral securing the reinsurance recoverables. The failure of a reinsurer to meet its obligations to us, whether due to insolvency, dispute, or other unwillingness or inability to pay, or due to our inability to access sufficient collateral to cover our liabilities, could have a material adverse effect on our results of operations and financial condition.

The availability and cost of reinsurance are determined by market conditions beyond our control. There is no guarantee that our desired amounts of reinsurance will be available in the marketplace in the future. In addition, available capacity may not be on terms we deem appropriate or acceptable or with companies with whom we want to do business. This could impact our ability to write certain products and have a material adverse effect on our results of operations and financial condition.

Market Competition and Broker Reliance

Competition in the insurance markets could reduce profits from our insurance operations. Insurance markets are highly competitive. We compete on an international and regional basis with major U.S., Bermuda, U.K., and other international insurers and with underwriting syndicates, some of which have greater financial, marketing, and management resources than we do, have greater access to "big data," and may be able to offer a wider range of, or more sophisticated, commercial and personal lines products. Recent industry consolidation, including business combinations among insurance and other financial services companies, has resulted in larger competitors with even greater financial resources. In addition, capital market participants have created alternative products that are intended to compete with insurance products.

Similar to other industries, the insurance industry is undergoing rapid and significant technological and other changes. There is increasing focus by traditional insurance industry participants, technology companies, insurtech start-up companies, and others on using technology and innovation, including artificial intelligence, to simplify and improve the customer experience, increase efficiencies, redesign products, alter business models, and effect other potentially disruptive changes in the insurance industry. If we do not anticipate, keep pace with, and adapt to technological and other changes impacting the insurance industry, it will harm our ability to compete, decrease the value of our products to customers, and materially and adversely affect our business. For example, competitors that deploy artificial intelligence and advanced analytics at scale, or that have access to data sets we cannot use for legal or practical reasons, may achieve superior underwriting, claims, and expense outcomes. Furthermore, innovation, technological change and changing customer preferences in the markets in which we

10K - 22

operate also pose other risks to our businesses. For example, they could result in increasing our service, administrative, policy acquisition. or general expenses as we seek to distinguish our products and services from those of our competitors or otherwise keep up with such innovation and changes. Increased competition could result in fewer submissions, lower premium rates, and less favorable policy terms and conditions, which could reduce our underwriting profits, or within our fronting operations, our operating profits, and have a material adverse effect on our results of operations and financial condition.

The historical cyclicality in the property and casualty insurance industry could have a material adverse effect on our ability to improve or maintain underwriting profits or to grow or maintain premium volume. The insurance markets have historically been cyclical, characterized by extended periods of intense price competition due to excessive underwriting capacity, and alternative sources of capital, as well as periods when shortages of capacity permitted more favorable rate levels. Among our competitive strengths have been our specialty product focus and our niche market strategy. These strengths also make us vulnerable in periods of intense competition to actions by other insurance companies who seek to write additional premiums without appropriate regard for underwriting profitability. At times, it could be very difficult for us to grow or maintain premium volume levels without sacrificing underwriting profits. If we are not successful in maintaining rates or achieving rate increases, it may be difficult for us to improve or maintain underwriting profits or to grow or maintain premium volume levels.

We depend on a few brokers for a large portion of our premiums and the loss of business provided by any one of them could have a material adverse effect on us. We market our insurance products worldwide through brokers. For the year ended December 31, 2025, our top five independent brokers represented 37% of the gross premiums written by our underwriting operations. Loss of all or a substantial portion of the business provided by one or more of these brokers could have a material adverse effect on our business.

Investments

Our insurance results may be impacted by changes in interest rates, foreign currency exchange rates, U.S. and international monetary and fiscal policies, and broader economic conditions. We receive premiums from customers for insuring their risks. These funds are invested until they are needed to pay policyholder claims. Fluctuations in the value of those investments can occur as a result of, among other things, changes in interest rates, foreign currency exchange rates, and U.S. and international fiscal, monetary and trade policies as well as broader economic conditions (including, for example, significant or prolonged inflation or deflation). Although we attempt to take measures to manage the risks of investing in these changing environments, we may not, in the short term or at all, be able to mitigate our sensitivity to them effectively. Despite our mitigation efforts, which include effectively matching target asset duration and currency to the duration and currency of the related loss reserves, these factors could have a material adverse effect on our results of operations and financial condition.

We invest a significant portion of the capital required to be held at our insurance companies in equity securities. Our insurance companies hold a significant amount of their required capital in the form of equity securities. Equity securities have historically produced higher returns than fixed maturity securities over long periods of time; however, investing in equity securities may result in significant variability in the fair value of the equity investments held by our insurance companies from one period to the next, including as as result of broader economic conditions. In volatile financial markets, our insurance companies could experience significant declines in the fair value of their equity investments, which would result in a material decrease in the value of the capital they hold to satisfy regulatory requirements. A material decrease in the value of the capital held by our insurance companies may have a material adverse effect on our ability to carry out our business plans and may require us to contribute additional capital to our insurance companies, either of which could have a material adverse effect on our results of operations or financial condition. See also, "We may require additional capital in the future, which may not be available or may only be available on unfavorable terms."

Financial Strength

Our insurance companies are rated by various rating agencies, and a downgrade or potential downgrade in one or more of these ratings could have a material adverse effect on us. Financial strength ratings are an important factor in establishing the competitive position of insurance companies. Certain of our insurance subsidiaries are rated by various rating agencies. Our financial strength ratings are subject to periodic review and are subject to revision or withdrawal at any time. The financial strength ratings of our insurance subsidiaries are significantly influenced by their statutory surplus amounts, capital adequacy ratios, and other financial metrics. Rating agencies may implement changes to their ratings methodologies or internal models that have the effect of increasing or decreasing the amount of capital our insurance subsidiaries must hold or restricting how the company may deploy its capital in order to maintain our current ratings. For example, for certain of our insurance subsidiaries, rating agencies may take into account in their calculations the collateral provided to us by reinsurers. A

10K - 23

change in this practice could adversely impact our ratings. We cannot be sure that we will be able to retain our current, or any future, ratings. If our ratings are reduced from their current levels by one or more rating agencies, our competitive position in our target markets within the insurance industry could suffer and it would be more difficult for us to market our products. A ratings downgrade could result in a substantial loss of business as policyholders and ceding company clients move to other companies with higher financial strength ratings. In addition, upon a ratings downgrade or decline in an insurance company's capital in excess of specified amounts, certain of our reinsurance contracts permit the cedent to require us to post collateral, recapture business, terminate the contract, or to otherwise exercise remedies that could adversely affect us. While we maintain capital levels at or in excess of regulatory requirements, the exercise of these contractual rights could, under certain circumstances, limit an insurance company's ability to pay dividends or make distributions to us. In addition, these contractual requirements could be triggered during periods of financial stress or adverse market conditions, when access to capital may be more limited. A ratings downgrade could also have a material adverse effect on our liquidity, including the availability of our letter of credit facilities, and limit our access to capital markets, increase our cost of borrowing or issuing debt and require us to post collateral.

Additionally, rating agencies may evaluate our holding company and insurance subsidiaries on a consolidated basis. Adverse developments impacting our holding company could influence the financial strength ratings of our insurance subsidiaries. See also, "Risks Primarily Related to Our Holding Company and Operating Structure".

The amount of capital that our insurance subsidiaries have and must hold to maintain their financial strength and meet other requirements can vary significantly from time to time and is sensitive to a number of factors, some of which are outside of our control. Capital requirements for our insurance subsidiaries are prescribed by the applicable insurance regulators, while rating agencies establish requirements that inform ratings for our insurance subsidiaries. Projecting surplus and the related capital requirements is complex and requires making assumptions regarding how our insurance businesses will perform within the broader macroeconomic environment. Insurance regulators and rating agencies evaluate company capital through financial models that calculate minimum capitalization requirements based on risk-based capital formulas for property and casualty insurance groups and their subsidiaries. In any particular year, capital levels and risk-based capital requirements may increase or decrease depending on a variety of factors including the mix of business written by our insurance subsidiaries and correlation or diversification in the business profile, the amount of additional capital our insurance subsidiaries must hold to support business growth, the value of securities in our investment portfolio, changes in interest rates, and foreign currency exchange rates, and changes to the regulatory and rating agency models used to determine our required capital.

Insurance Regulation

Our insurance subsidiaries are subject to supervision and regulation that may have a material adverse effect on our operations and financial condition. Our insurance subsidiaries are subject to supervision and regulation by the regulatory authorities in the various jurisdictions in which they conduct business, including foreign and U.S. state insurance regulators. Regulatory authorities have broad regulatory, supervisory, and administrative powers relating to, among other things, data protection and data privacy, cybersecurity, solvency standards, licensing, coverage requirements, product terms and conditions, policy rates and forms, business and claims practices, disclosures to consumers, and the form and content of financial reports. In some instances, we follow practices based on our interpretations of regulations or practices that we believe may be generally followed by the industry. These practices may turn out to be different from the interpretations of regulatory authorities. Insurance regulatory authorities have broad authority to initiate investigations or other proceedings, and, in connection with a failure to comply with applicable laws and regulations, could impose adverse consequences, including fines, penalties, injunctions, denial or revocation of an operating license or approval, increased scrutiny or oversight, limitations on engaging in a particular business, or redress to clients. These actions also could result in negative publicity, reputational damage or harm to client, employee or other relationships. Additionally, regulatory and legislative authorities continue to implement enhanced or new regulatory requirements to assure the stability of insurance companies or enhance policyholder protections or, in certain instances, intended to prevent or mitigate future financial crises. It is possible that requirements or guidance under one jurisdiction, such as the U.S., may be contradictory to or divergent from requirements or guidance in other jurisdictions where we operate, such as the E.U. Regulatory authorities also may seek to exercise their supervisory or enforcement authority in new or more extensive ways, such as increased capital requirements. Any of these actions, if they occur, could affect the competitive market, how we are regulated, and the way we conduct our business or manage our capital, and could result in lower revenues and higher costs. As a result, such actions could have a material adverse effect on our results of operations and financial condition.

Regulators may challenge our use of fronting arrangements in jurisdictions in which our capacity providers are not licensed. Our program services operations enter into fronting arrangements with general agents and domestic and foreign capacity providers that want to access specific U.S. and foreign property and casualty insurance business in jurisdictions in

10K - 24

which the capacity providers are not licensed or are not authorized to write particular lines of insurance. Some insurance regulators may object to these fronting arrangements. In certain jurisdictions, an insurance regulator has the authority to prohibit an authorized insurer from acting as an issuing carrier for an unauthorized insurer. In addition, insurance regulators in jurisdictions in which there is no such statutory or regulatory prohibition, could deem the assuming insurer to be transacting insurance business without a license and the issuing carrier to be aiding and abetting the unauthorized sale of insurance.

If regulators in any of the jurisdictions where we conduct fronting business were to prohibit or limit those arrangements, we would be prevented or limited from conducting that business for which a capacity provider is not authorized in those jurisdictions, unless and until the capacity provider is able to obtain the necessary licenses. This could have a material adverse effect on our results of operations and financial condition, which in turn could result in an impairment of the goodwill or intangible assets related to this business.

Risks Primarily Related to Our Insurance-Linked Securities (ILS) Operations

Our ILS operations involve management of third-party capital, which may expose us to risks. Our ILS operations may owe certain legal duties and obligations to third-party investors. A failure to fulfill any of those duties or obligations could result in significant liabilities, penalties, or other losses, and harm our businesses and results of operations. In addition, third-party investors may decide not to renew their investments in the funds we manage, which could materially impact the financial condition of those funds, and could, in turn, have a material adverse effect on our results of operations and financial condition. Moreover, we may not be able to maintain or raise additional third-party capital for the funds we manage or for potential new funds and therefore we may forego existing or potential management fee generating opportunities.

Our ILS operations may experience losses or disruptions from catastrophes and other significant, infrequent loss events. Losses from catastrophes and other significant, infrequent loss events may have a material adverse effect on the ability of our ILS operations to raise and retain investor capital, resulting in a decline in assets under management and in turn, reduce potential management fee generating opportunities. We use various modeling techniques and data analytics to analyze and estimate exposures, loss trends, and other risks associated with our ILS businesses. The usefulness of our models depends on the extent to which our actual experience is consistent with assumptions we use in our models and ultimate model outputs, which may from time-to-time contain inaccuracies. See also, "We may experience losses or disruptions from catastrophes and certain other, significant infrequent loss events."

Risks Related to All of Our Operations

Market Competition

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. From time to time, to protect and grow market share or improve our efficiency, we invest in strategic initiatives to:

•develop products that insure risks we have not previously insured, include new coverages or change coverage terms;

•change commission terms;

•change our underwriting processes;

•improve business processes and workflow to increase efficiencies and productivity and to enhance the experience of our customers and producers;

•expand distribution channels; and

•enter geographic markets where we previously have had relatively little or no market share.

We may not be successful in these efforts, and even if we are successful, they may increase or create the following risks, among others:

•demand for new products or expansion into new markets may not meet our expectations;

•new products and expansion into new markets may increase or change our risk exposures, and the data and models we use to manage those exposures may not be as effective as those we use in existing markets or with existing products;

•models underlying automated underwriting and pricing decisions may not be effective;

10K - 25

•efforts to develop new products or markets or to change commission terms may create or increase distribution channel conflicts;

•in connection with the conversion of existing policyholders to a new product, some policyholders' pricing may increase while the pricing for other policyholders may decrease, the net impact of which could negatively impact retention and profit margins;

•changes to our business processes or workflow, including the use of new technologies, may give rise to execution risk and cost more and take longer than expected; and

•increased usage of artificial intelligence by us and third parties and the evolving regulatory landscape may increase underwriting and regulatory risk, while also presenting opportunity risk if we do not leverage artificial intelligence appropriately.

These efforts may require us to make substantial expenditures, which may negatively impact results in the near term, and if not successful, could materially and adversely affect our results of operations.

Legal and Regulatory Risks

The legal and regulatory requirements applicable to our businesses are extensive. Failure to comply could have a material adverse effect on us. Each of our businesses is highly dependent on the ability to engage on a daily basis in a large number of financial and operational activities, including, among others, insurance underwriting, claim processing, investment activities, the management of third-party capital, and providing products and services to businesses and consumers, many of which are highly complex. These activities are subject to internal guidelines and policies, as well as legal and regulatory requirements, including, among others, those related to privacy and data security, artificial intelligence, economic and trade sanctions, anti-corruption, anti-bribery, global finance and investments, customer protection, and insurance matters. Our continued expansion into new businesses, distribution channels and markets brings about additional requirements. While we believe that we have adopted adequate and effective risk management and compliance programs, compliance risks remain, particularly as we become subject to additional rules and regulations. Failure to comply with, or to obtain, appropriate authorizations or exemptions under any applicable laws and regulations could result in restrictions on our ability to do business or undertake activities that are regulated in one or more of the jurisdictions in which we conduct business. Any such failure could also subject us to fines, penalties, equitable relief, and changes to our business practices. In addition, a failure to comply could result in defaults under our senior unsecured debt agreements or credit facilities or damage our businesses or our reputation.

Compliance with applicable laws and regulations is personnel- and systems-intensive. Shareholder activism, the current political environment, and the current high level of government intervention and regulatory reform may lead to substantial and complex new regulations and compliance obligations. Any changes in, or the enactment of new laws and regulations may increase the complexity of the regulatory environment in which we operate, which could materially increase our direct and indirect costs for compliance and other expenses of doing business, and have a material adverse effect on our results of operations and financial condition. For example, the use of artificial intelligence by us or third-party providers may subject us to data privacy, intellectual property, and general regulatory risk, particularly in light of emerging regulation on the use of artificial intelligence.

Losses from legal and regulatory actions may have a material adverse effect on us. From time to time, we may be involved in various legal actions, including at times multi-party or class action litigation, some of which involve claims for substantial or indeterminate amounts. A significant unfavorable outcome in one or more of these actions could have a material adverse effect on our results of operations and financial condition. We are also involved, from time to time, in various regulatory actions, investigations, and inquiries, including market conduct exams by insurance regulatory authorities. If a regulatory authority takes action against us or we enter into a consent order or agreement to settle a matter, a regulatory authority has the option to require us to pay substantial fines or implement remedial measures that could prove costly or disruptive to our businesses and operations. Even if an unfavorable outcome does not materialize, these matters could have an adverse impact on our reputation and result in substantial expense and disruption.

Changes in tax laws, rates, or regulations could have a material adverse effect on us. Changes in federal, state, or foreign tax laws, rates, or regulations, or their interpretation and application, could adversely affect our tax positions or tax liabilities, require us to make adjustments in our operations or tax strategies, and increase our overall tax burden.

We are subject to laws and regulations relating to economic and trade sanctions and bribery and corruption, the violation of which could have a material adverse effect on us. We are required to comply with the economic and trade

10K - 26

sanctions and embargo programs administered by the U.S. Department of the Treasury's Office of Foreign Assets Control and similar multi-national bodies and governmental agencies worldwide, as well as applicable anti-corruption and anti-bribery laws and regulations of the U.S. and other jurisdictions where we operate. In some cases, we must comply with many new economic, financial, and trade sanctions that are imposed over a short period of time, as occurred with the conflict between Russia and Ukraine. A violation of a sanction, embargo program, or anti-corruption law could subject us, and individual employees, to a regulatory enforcement action as well as significant civil and criminal penalties. In addition, a violation could result in defaults under our outstanding indebtedness or credit facilities or damage our businesses or our reputation. Those penalties or defaults, or damage to our businesses or reputation, could have a material adverse effect on our results of operations and financial condition. In some cases, the requirements and limitations applicable to the global operations of U.S. companies and their affiliates are more restrictive than, and may even conflict with, those applicable to non-U.S. companies and their affiliates, which also could have a material adverse effect on our results of operations and financial condition.

Employee error and misconduct may be difficult to detect and prevent and may result in significant losses. We run the risk of misconduct by employees across our businesses. Instances of misconduct, fraud, illegal acts, errors, failure to document transactions properly or to obtain proper internal authorization, or failure to comply with regulatory requirements or our internal policies may result in losses or reputational damage. It is not always possible to detect, deter, or prevent employee errors or misconduct or fraud, and the controls and trainings that we have in place to mitigate these activities may not be sufficient or effective in all cases.

Global Operations

We have substantial international operations and investments, which expose us to increased political, civil, operational, and economic risks. A substantial portion of our revenues and income is derived from our operations and investments outside the U.S., including from the U.K., the E.U., Bermuda, Canada, and Asia Pacific. Our international operations and investments expose us to increased political, civil, operational, and economic risks. Deterioration or volatility in foreign and international financial markets or general economic and political and civil conditions could adversely affect our operating results, financial condition, and liquidity. Concerns about the economic conditions, capital markets, political, civil, and economic stability and solvency of certain countries may contribute to global market volatility. Political and civil changes in the jurisdictions where we operate and elsewhere, some of which may be disruptive, can also interfere with our customers and our activities in a particular location. Our international operations also may be subject to a number of additional risks, particularly in emerging economies, including restrictions such as price controls, capital controls, currency exchange limits, ownership limits, and other restrictive or anti-competitive governmental actions or requirements, which could have a material adverse effect on our businesses.

General economic, market, or industry conditions could lead to investment losses, adverse effects on our businesses, and limit our access to the capital markets. 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 and volatility in foreign currency exchange rates, commodity and energy prices, and interest rates; volatility in the credit and capital markets; changes in U.S. government debt ratings; the imposition of duties, tariffs, and other changes in international trade regulation and other factors, could lead to: substantial realized and unrealized investment losses in future periods; changes in the carrying value of our other assets and liabilities; declines in demand for, or increased frequency and severity of claims made under, our insurance products; disruptions in global supply chains and increased costs of inputs for our products and services; reduced demand for our services and the products we sell and distribute; and limited or no access to the capital markets. Any of these impacts could have a material adverse effect on our results of operations, financial condition, debt and financial strength ratings, or the adequacy of our insurance subsidiaries' capital. Many of our businesses have been, and may continue to be, adversely affected by increased costs of labor and materials and declines in demand for certain products and services due to economic and industry specific conditions. In addition, beginning in 2025, the U.S. announced a series of new or increased tariffs on certain foreign imports, some of which were recently invalidated by the Supreme Court. These tariffs, and any additional duties, tariffs, and other trade barriers, and retaliatory countermeasures by other countries, may adversely affect the price and availability of goods for our businesses and the demand for our products and services. Additionally, any such measures or countermeasures may increase inflationary pressure on our insured losses, including costs of claims, loss adjustment expenses, and other operating costs. These impacts may be material, and our efforts to mitigate these impacts may not be successful and, even when they are successful, there may be a time lag before the impacts of these efforts are reflected in our results.

Our businesses, results of operations, and financial condition could be adversely affected by ongoing regional or military conflicts and related disruptions in the global economy. The global economy has been, and may in the future be, negatively impacted by regional or military conflicts, for example, the on-going conflicts between Russia and Ukraine and in

10K - 27

Israel and surrounding areas. We may have operations in areas affected by a conflict, and some of our businesses may be adversely affected by a conflict and its effects. Within our underwriting operations, we may have insurance contracts with exposure to losses attributed or corollary to a conflict, such as losses related to our coverage of ships, cargo, trade credit and inventory. Our other operations also may have direct exposure to customers and vendors in an affected area. Certain of our businesses may experience shortages in materials and increased costs for transportation, energy, and raw materials due in part to the negative impact of a conflict on the global economy.

Furthermore, governments in the U.S., U.K., and E.U., among others, may impose export controls on certain products and financial and economic sanctions on certain industry sectors and parties in affected areas. These export controls and sanctions, or our failure to comply with them, could result in restrictions on our ability to do business in one or more of the jurisdictions in which we conduct business or have the other adverse effects previously discussed under "We are subject to laws and regulations relating to economic and trade sanctions and bribery and corruption, the violation of which could have a material adverse effect on us."

We are unable to predict the impact an ongoing conflict may have on our businesses or the global economy. The impact of geopolitical tensions related to these conflicts, including increased trade barriers or restrictions on global trade, is unknown and could result in, among other things, heightened cybersecurity threats, supply disruptions, protracted or increased inflation, increased energy costs, lower consumer demand, fluctuations in interest and foreign exchange rates, and increased volatility in financial markets, any of which could adversely affect our businesses, results of operations and financial condition. In addition, an ongoing conflict may have the effect of triggering or intensifying many of the risks described under this Item 1A Risk Factors.

Information Technology Systems and Third-Party Systems and Service Providers

Information technology systems that we use could fail or suffer a security breach or cyberattack, which could have a material adverse effect on us or result in the loss of regulated or sensitive information. Our businesses are dependent upon the operational effectiveness and security of our enterprise systems and those maintained by third parties. Among other things, we rely on these systems to interact with producers, insureds, customers, clients, and other third parties, to perform actuarial and other modeling functions, to underwrite business, to prepare policies and process premiums, to process claims and make claims payments, to prepare internal and external financial statements and information, and to engage in a wide variety of other business activities. A significant failure of our enterprise systems, or those of third parties upon which we may rely, whether because of a natural disaster, network outage or a cyberattack on those systems could compromise our personal, confidential, and proprietary information as well as that of our customers and business partners, impede or interrupt our business operations and could result in other negative consequences, including remediation costs, loss of revenue, additional regulatory scrutiny and fines, litigation, and monetary and reputational damages. In addition, if we are unable to innovate, develop, and acquire new technology, it may leave us more susceptible to these attacks. Like other companies, we have been subject to cyberattacks, malicious viruses and malware, and denial of service attacks and expect that this will continue in the future with greater sophistication and frequency. The risk and severity of such attacks could increase as artificial intelligence is used by threat actors to identify vulnerabilities and conduct increasingly sophisticated attacks. Despite any controls or protective actions we take against such attacks, those measures may be insufficient to prevent, or mitigate the effects of, a natural disaster, network outage or a cyberattack on our systems. This could result in liability to us, cause our data to be corrupted or stolen and cause us to commit resources to correct those failures.

In addition, we are subject to numerous data privacy and cybersecurity laws and regulations enacted in the jurisdictions in which we do business. A misuse or mishandling of personal, confidential, or proprietary information being sent to or received from a customer, business partner, employee, or third party could damage our businesses or our reputation or result in significant monetary damages, regulatory enforcement actions, fines, and criminal prosecution in one or more jurisdictions. For example, under the European General Data Protection Regulation there are significant punishments for non-compliance which could result in a penalty of up to 4% of a firm's global annual revenue. In addition, a violation of data privacy laws and regulations could result in defaults under our outstanding indebtedness or credit facilities. Those monetary damages, penalties, regulatory or legal actions or defaults, or the damage to our businesses or reputation, could have a material adverse effect on our results of operations and financial condition. Third parties who we utilize to perform certain functions are also subject to these risks, and their failure to adhere to these laws and regulations also could damage our businesses or reputation or result in regulatory intervention, which could have a material adverse effect on our results of operations and financial condition.

Further, we routinely transmit, receive, and store personal, confidential, and proprietary information by email and other digital means. Although we attempt to protect this personal, confidential, and proprietary information, we may be unable to do so in

10K - 28

all cases, especially with business partners and other third parties who may not have or use appropriate controls to protect personal, confidential, and proprietary information.

While we maintain cyber risk insurance providing first-party and third-party coverages, that insurance may not cover all costs associated with the consequences of an enterprise failure, cyberattack, or breach of systems. A material cyber security breach could have a material adverse effect on our results of operations and financial condition. See also, "We may experience losses or disruptions from catastrophes and other significant, infrequent loss events."

Third-party providers may perform poorly, breach their obligations to us, or expose us to enhanced risks. Certain of our business functions are performed by third-party providers, and these providers may not perform as expected or may fail to adhere to the obligations owed to us. For example, certain of our business units rely on relationships with a number of third-party administrators under contracts pursuant to which these third-party administrators manage and pay claims on our behalf and advise us with respect to case reserves. In these relationships, we rely on controls incorporated in the provisions of the administration agreement, as well as on the administrator's internal controls, to manage the claims process within our prescribed parameters. In addition, certain of our business units use managing general agents, general agents and other producers to write and administer business on our behalf within prescribed underwriting authorities. Although we monitor these administrators, agents, producers, and other service providers on an ongoing basis, our monitoring efforts may not be adequate, or our service providers could exceed their authorities or otherwise breach obligations owed to us, which could result in operational disruption, reputational damage, and regulatory intervention and otherwise have a material adverse effect on our results of operation and financial condition.

In addition, we utilize third parties to perform certain technology and business process functions, such as data center hosting, cloud based operating environments, human resources, and other outsourced services. If these third-party providers do not perform as expected, we may experience operational difficulties, increased costs, and a loss of business, or we may not realize expected productivity improvements or cost efficiencies. Our use of third parties to perform certain technology and business process functions may expose us to risks related to privacy and data security, including through their use of artificial intelligence without our knowledge or below our standards, which could result in monetary and reputational damages. We may be further exposed to risks associated with artificial intelligence and machine learning technology if third-party service providers or any counterparts, whether known or unknown to us, use such technology in their business activities. In addition, our ability to receive services from third-party providers might be impacted by a wide variety of factors, including political and civil instability, supply chain disruptions, volatility, or disruptions in the financial markets, wide-spread health issues, unanticipated or additional regulatory requirements or policies. As a result, our ability to conduct our businesses may be adversely affected.

Pandemics

Pandemics have had, and could have, material adverse effects on us. The effects of a pandemic, and related governmental responses, may be wide-ranging, costly, and disruptive, and may develop rapidly, resulting in material adverse effects on our operations, and on our results of operations and financial condition, as was the case with COVID-19. Factors that give rise, or may give rise, to those effects include, or may include, the following, as well as others that we cannot predict:

•Insured or reinsured losses from pandemic-related claims that are different, or more extensive, than we expect;

•Government actions or judicial decisions related to insurance or reinsurance coverages or rates, including, for example, requiring retroactive coverage of claims or expanding the scope of coverage;

•Disputes, lawsuits, and other legal actions challenging the promptness of coverage determinations, or the coverage determinations themselves, under applicable insurance or reinsurance policies, resulting in increased claims, litigation and related expenses;

•Disruptions, delays, and increased costs and risks related to having limited or no access to our facilities, workplace re-entry, employee safety concerns, and reductions or interruptions of critical or essential services;

•Continually changing business conditions and compliance obligations; and

•Short or long-term impacts on the cost, availability, or timeliness of required raw materials, supplies, or services provided by third parties, including services provided by state, federal, or foreign governments or government agencies.

In addition, a pandemic may, as was the case with COVID-19, have the effect of triggering or intensifying many of the risks described elsewhere under this Item 1A Risk Factors.

10K - 29

Climate Change

The impacts of climate change, and legal or regulatory measures to address climate change, may adversely affect our results of operations or financial condition. Our businesses, results of operations, and financial condition could be impacted by risks associated with climate change, including:

•changes from legislation, regulation, and court decisions that:

◦create economic and regulatory uncertainty,

◦increase our compliance costs,

◦impose liability on or increase exposure for our policyholders not contemplated during our underwriting,

◦change our ability to provide insurance coverage to certain policyholders, or

◦impose new or additional requirements that increase the costs associated with, or disrupt, sourcing, manufacturing, and distribution of, our products and services,

•changes in the frequency, severity, and location of weather-related catastrophes, such as hurricanes, tornados, windstorms, floods, wildfires, and other extreme weather events, which may:

◦result in insured losses that exceed our expectations or make it more difficult for us to predict and model catastrophic events, reducing our ability to accurately price our exposure to such events and mitigate our risks,

◦make it more difficult or expensive for us to obtain reinsurance at desired levels, or

◦increase physical risks to and impacts on our operations,

•changing demand for insurance coverage we provide, such as demand from industries that produce or use carbon-based energy including those transitioning from those energy sources, decreased availability of reinsurance available for coverages we provide for carbon intensive industries, or increased claims and losses related to those industries, and

•losses on our invested assets, including from:

◦changes in supply and demand,

◦advances in low-carbon technology and renewable energy development,

◦effects of extreme weather events on the physical and operational exposure of industries and issuers, and

◦the transition that companies make towards addressing climate risk in their own businesses.

Item 1C. CYBERSECURITY

Markel Group is a holding company comprised of a diverse group of businesses and investments. Our specialty insurance business, Markel Insurance, sits at the core of our company. Markel Group also owns controlling interests in a diverse portfolio of businesses that operate in a variety of other industries. Each of our businesses is required to maintain cybersecurity insurance coverage and has its own independently managed cybersecurity and data protection program that is tailored to its operations and risk profile.

Markel Insurance

In order to maintain a strong cybersecurity program, Markel Insurance uses a variety of controls and technology tools designed to identify, detect, prevent, respond to, and recover from security threats. Markel Insurance undergoes regular security audits including a System and Organization Controls, or SOC, audit for cybersecurity conducted annually by independent auditors in which cybersecurity threats are identified and assessed. Markel Insurance regularly tests aspects of its internal security and conducts security risk interviews and assessments on third parties with whom it does business, depending on the nature of the relationship. Markel Insurance has invested in technology that assists its risk management teams in measuring and addressing weaknesses in its third-party and supply chain community. Markel Insurance performs continuous monitoring of all its critical third parties to ensure they are maintaining acceptable levels of security controls and remediating any known weaknesses.

Markel Insurance participates in the Financial Services Information Sharing and Analysis Center to share information about the latest cyber threats and preparedness measures. Markel Insurance also shares threat intelligence information with other partners. Markel Insurance has a cybersecurity incident response plan, as well as a crisis management plan, that cover cyber events, including a process for determining the materiality of cyber events that includes evaluation by a cross functional crisis management group including security, information technology, finance, legal, and business and escalation to Markel Group

10K - 30

senior management as warranted by the severity of the situation. An internal team engages in tabletop exercises on a regular basis to enhance preparedness for such situations.

Information security and data protection risks are the responsibility of all employees. Markel Insurance has a mandatory training program covering a variety of security and data protection disciplines. In addition, all Markel Insurance employees are required to acknowledge annually policies on acceptable use of Markel Insurance's technology resources and enterprise information security. Contractors are required to provide certain representations and certifications relating to information security.

The Markel Insurance information security and data protection program is led by a Chief Information Security Officer (CISO) who supervises a team of security and data protection professionals across the globe. The Markel Insurance global information security and data protection program leverages the Cybersecurity Framework from the National Institutes of Standards and Technology as well as industry best practices. The program also is able to map to both ISO (International Organization for Standardization) and BSI (British Standards Institution) among other cybersecurity standards. Markel Insurance's CISO has been with Markel Insurance 15 years and has 24 years' experience in information technology, with 19 years in information technology security, and is a certified Information Systems Security Professional (CISSP).

Markel Group, State National, and Nephila

Information technology systems and services, including cybersecurity, used by the small team of individuals at the Markel Group holding company are provided and/or administered by teams within Markel Insurance, consistent with the practices outlined above. State National and Nephila each manage their own cybersecurity programs, with incident management support available from Markel Insurance.

Other Operating Businesses

Each of our other operating businesses maintains its own IT infrastructure, often supported by third-party providers, to meet its specific business needs. As a result, cybersecurity risk is decentralized and not concentrated in a single system or service provider. Given the diversity of these businesses, systems, and providers, each business tailors its program to its unique risks and operations. Management at each business is responsible for assessing and managing its cybersecurity risks, including selecting appropriate IT systems and service providers.

Markel Group has established processes for these businesses to share information about how they assess, identify, and manage cybersecurity risk, including material cybersecurity incidents, with Markel Group management. For example, Markel Group requires real-time reporting of cybersecurity incidents by these businesses to understand how the matters are being managed, assess whether public disclosure is required, with escalation to Markel Group senior management as warranted by the severity of the situation. Depending on the cybersecurity incident, third parties may be engaged by these businesses to assist in understanding and managing the event.

Given each business varies in size and complexity, the individual or individuals responsible for managing cybersecurity risks varies by business. In all instances, ultimate responsibility rests with the Chief Executive Officer of each business.

Markel Group Board Oversight

The Markel Group Board of Directors oversees Markel Group's risk management framework on an enterprise-wide basis, which includes cybersecurity risks. Periodic reports are provided to the Markel Group Board of Directors by members of management which, among other things, seek to systematically identify the principal risks facing our businesses and the manner in which such risks are addressed. For cybersecurity, this includes a review of the cybersecurity program and its governance, active and planned initiatives, protection and prevention matters, detection and response measures, and the threat landscape.

Cybersecurity Risks

No previous cybersecurity incident has had, or is reasonably likely to have, a material adverse effect on Markel Group, its business strategy, results of operations, or financial condition. For risks related to cybersecurity threats, see Item 1A Risk Factors, including under "Information technology systems that we use could fail or suffer a security breach or cyberattack, which could have a material adverse effect on us or result in the loss of regulated or sensitive information."

Item 7. MANAGEMENT'S DISCUSSION & ANALYSIS OF FINANCIAL CONDITION AND RESULTS OF OPERATIONS

The following discussion and analysis includes discussion of changes in our results of operations and financial condition from 2024 to 2025 and from 2023 to 2024 and should be read in conjunction with the consolidated financial statements and related notes included under Item 8, Item 1 Business, Item 1A Risk Factors, and "Safe Harbor and Cautionary Statement". 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 (the Company). For a discussion of our significant accounting policies, see note 1 of the notes to consolidated financial statements included under Item 8. Item 7 is divided into the following sections:

•Capital Performance

•Results of Operations

•Liquidity and Capital Resources

•Non-GAAP Financial Measures

•Critical Accounting Estimates

•Safe Harbor and Cautionary Statement

In 2025, we made notable changes to our financial reporting, including the re-segmentation of our businesses, the expansion of both consolidated and segment financial metrics, and the addition of detail regarding our business strategy, among others. See note 2 of the notes to consolidated financial statements for additional details on the changes to our reportable segments.

Capital Performance

Markel Group is a dynamic system that strives to relentlessly compound shareholder capital at attractive rates across decades. We are responsible for capital allocation across our businesses and use a variety of metrics for each part of the Markel Group system, among other factors, to help inform these activities. Our capital allocation decisions are made with a long-term perspective that considers an array of qualitative and quantitative factors in the context of our capital allocation framework. See Item 1 Business "Relentlessly Compounding Shareholder Capital" for details of our capital allocation options and investment principles.

We believe that our capital performance metrics are best viewed over longer periods of time. To better align with this long-term perspective, we use five-year time periods to assess capital performance.

The five-year compound annual growth rate (CAGR) of intrinsic value per share is one of the ways by which we monitor the success of our capital allocation decisions and overall returns from the consolidated Markel Group system.

For our Markel Insurance business, we measure capital efficiency using return on equity, with a focus on the five-year average annual return on equity.

For our Industrial, Financial, and Consumer and Other segments, we look at a variety of capital efficiency metrics given the diverse businesses within these segments.

Intrinsic Value Per Share Growth

As a diverse holding company, we use growth in intrinsic value per share as a measure to help us evaluate the value created by our businesses over five-year periods of time. While intrinsic value does not represent a precise valuation of our business, we believe growth in intrinsic value per share, considered among an array of other qualitative and quantitative factors, offers a useful tool to investors and management in understanding long-term value creation trends. A straightforward methodology can be used to measure intrinsic value per share growth using data from our financial statements.

10K - 35

First, we take an adjusted earnings metric and apply a consistent multiple to arrive at an earnings valuation. We exclude certain non-cash items from our adjusted earnings metric, such as amortization, as well as income attributed to our public equity portfolio and income from our cash and short-term investments, which are valued separately in our calculation. Using a three-year average of earnings in our calculation helps mitigate the impact of cyclicality and non-recurring items in the earnings valuation.

We consider a range of multiples in our earnings valuation calculation that reflects the diversity of our sources of cash flows, with 12x as the midpoint. Regardless of the multiple used, we believe using a consistent multiple for each year in the calculation is important when assessing the five-year compound annual growth rate in intrinsic value per share.

Second, we add certain items from our balance sheet that are not included in the earnings valuation. The balance sheet component of the valuation consists of adding cash, short-term investments, and equity securities, then subtracting debt, preferred stock, and noncontrolling interests.

The sum of the earnings and balance sheet valuations divided by the number of shares outstanding represents our estimate of intrinsic value per share from which to calculate growth.

Our simplified intrinsic value per share growth calculation may differ from calculations that others may perform, and our stock price growth may vary significantly from our intrinsic value growth calculation. We believe that the key with any calculation is applying a consistent methodology to measure the compound annual growth in intrinsic value per share over five-year periods, which is aligned with our long-term aim of relentlessly compounding shareholder capital.

Markel Insurance Return on Equity

We believe return on equity is an important metric to evaluate the overall performance of Markel Insurance. This metric is representative of the total return generated by the business on the capital that it holds and provides a metric by which to evaluate Markel Insurance's capital efficiency.

Although we do not consider net investment gains and losses when assessing the periodic performance of our Markel Insurance segment, we believe it is important to consider the full contribution of the publicly traded equity securities held by Markel Insurance subsidiaries when evaluating the capital efficiency of the business.

Over the five-year period ended December 31, 2025, the average return on equity from Markel Insurance was 13%. The following table summarizes the calculation of return on equity for Markel Insurance.

(1) Interest expense on our senior notes is attributed to the return on Markel Insurance.

(2) Income tax expense is based on a 22% tax rate, which is representative of our typical effective rate, however, it does not represent actual income tax expense at Markel Insurance. Income taxes are managed on a consolidated basis across the Markel Group and are only attributed to the Markel Insurance segment when assessing its return on equity.

Capital Reconciliation

The following table summarizes the capital held by each of our segments, as well as a reconciliation to consolidated capital of Markel Group. Total capital is comprised of total equity, redeemable noncontrolling interests, total debt, and obligations for finance leases. Eliminations relate to intercompany loans to and from a corporate subsidiary, which are eliminated in consolidation.

Total operating revenues	$	15,513,233	$	14,813,544	$	14,279,576

In 2025, we updated the presentation of operating revenues to no longer include net investment gains and losses, and prior periods have been recast to conform to the updated presentation. Net investment gains and losses are predominantly derived from our investments in publicly traded equity securities and typically include significant unrealized gains and losses from market value movements.

We believe that net investment gains and losses, whether realized from sales or unrealized from market value movements, are distortive in understanding the short-term operating performance of our businesses. As such, we exclude net investment gains and losses from adjusted operating income. We believe adjusted operating income, both consolidated and by segment, is generally an accurate representation of the operating performance of our businesses in our periodic results.

The following table presents consolidated operating income and a reconciliation to consolidated adjusted operating income, as well as adjusted operating income by segment. Consolidated adjusted operating income is a non-GAAP measure. See "Non-GAAP Financial Measures" for additional details.

Global Reinsurance

In August 2025, Markel Insurance sold the renewal rights for business written in its Global Reinsurance division, and the division entered into run-off. Gross premium volume in 2025 attributed to the Global Reinsurance division was $1.0 billion. Underwriting results attributable to the Global Reinsurance division had a two point unfavorable impact on the Markel Insurance segment combined ratio in 2025 and a one point unfavorable impact in 2024 and 2023.

Premiums

2025 compared to 2024

The increase in underwriting gross premium volume in our Markel Insurance segment in 2025 was driven by significant growth within our personal lines and international professional liability product lines, as well as growth within our programs, marine and energy, and general liability product lines. These increases were partially offset by the impact of lower premium volume in our U.S. professional liability product lines, as a result of exiting our risk-managed directors and officers product line from our U.S. and Europe-based platforms. We concluded that the rates on the business written from these platforms were inadequate to meet our profitability targets, therefore, we stopped writing this product from our European platform in late 2024 and our U.S. platform in early 2025. We continue to write select risk-managed directors and officers accounts from our Bermuda-based platform.

The increase in fronting gross premium volume in 2025 was driven by growth of our property catastrophe programs with Nephila.

Net retention of underwriting gross premium volume was 79% in 2025 compared to 78% in 2024. Within our underwriting operations, we purchase 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 2025 was primarily due to the impact of the changes in underwriting gross premium volume in recent periods.

2024 compared to 2023

The increase in underwriting gross premium volume in our Markel Insurance segment in 2024 was driven by new business growth and more favorable rates within our personal lines, marine and energy, programs, and credit and surety product lines, partially offset by lower premium volume within select lines of our U.S. general liability and professional liability product lines. Gross premium volume within our U.S. general liability and professional liability product lines decreased $276.6 million in 2024 compared to 2023, which reflects decreased writings within our brokerage contractors, brokerage excess and umbrella, and risk-managed excess casualty general liability products and our risk-managed professional liability products as part of targeted underwriting actions aimed at achieving greater profitability within these product lines.

The increase in fronting gross premium volume in 2024 was driven by growth of our property catastrophe and specialty programs with Nephila.

Net retention of underwriting gross premium volume was 78% in 2024 compared to 81% in 2023. The decrease was driven by higher cession rates on our professional liability product lines in 2024 compared to 2023, as well as changes in mix of business as we decreased writings on select lines of our U.S. general liability product lines, which have lower cession rates than most other products within the segment.

The increase in earned premiums in 2024 was primarily due to the impact of the changes in underwriting gross premium volume in recent periods.

Rate Discussion

In 2025, we achieved modest rate increases overall across our diversified product portfolio. 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 in product lines where we are confident in the levels of rate adequacy.

Product lines achieving the most notable rate increases include our U.S. general liability product lines, as well as certain personal lines and programs product lines. Despite multiple years of rate increases, we continue to be cautious in selecting which risks to pursue and how much limit to deploy within certain subclasses of our U.S. general liability portfolio as we rebalance our portfolio. However, the rate increases for these product lines have generally been in line with, or better than, our assumptions for loss cost trends. As a result of the rate increases and overall profitability being achieved in our personal lines and programs product lines, we are increasing our premium writings in these lines.

Product lines with notable rate decreases include our U.S. workers' compensation product line, international energy and professional liability product lines, and our global cyber portfolios. More recently, rates for our U.S. property product lines also have decreased as market conditions have softened due to a lower level of natural catastrophe events in 2025.

Services and Other Income

The increase in services and other income in 2025 was primarily due to higher fronting fees driven by growth of our property catastrophe programs with Nephila, as previously discussed. Services and other income in 2024 was consistent with 2023.

Combined Ratio

Natural Catastrophes

The following table summarizes the impact of losses attributed to natural catastrophes on the Markel Insurance segment combined ratio. Losses from natural catastrophes in 2025 were attributed to the series of wildfires that occurred in southern California in January 2025. Losses from natural catastrophes in 2024 were attributed to Hurricane Helene and Hurricane Milton. Losses from natural catastrophes in 2023 were attributed to the Hawaiian wildfires and Hurricane Idalia.

Intellectual Property Collateral Protection Insurance

The following table summarizes the impact of intellectual property collateral protection insurance (IP CPI) losses on the Markel Insurance segment combined ratio.


	Year Ended December 31,
(dollars in thousands)	2025			2024			2023
Net losses and loss adjustment expenses	$	64,259		$	168,534		$	97,572
Impact on combined ratio	0.8		%	2.1		%	1.2		%

In 2023, we began to observe higher than expected levels of defaults on loans collateralized by intellectual property, for which we provided coverage to lenders through our IP CPI product line. We discontinued writing this product at the beginning of 2024. However, we continued to recognize losses in 2024 and 2025 as additional claim events occurred, which result from both a default on the loan and impairment of the underlying intellectual property. We believe any losses on our discontinued IP CPI product line in 2026 will not be material to the Markel Insurance segment.

2025 compared to 2024

Excluding losses attributed to natural catastrophes, the decrease in the Markel Insurance segment combined ratio in 2025 compared to 2024 was primarily attributable to a lower attritional loss ratio, which was driven by lower losses on our discontinued IP CPI product line. Additionally, the attritional loss ratio in 2025 was unfavorably impacted by large losses within our credit and surety product line and higher attritional loss ratios on our personal umbrella product line. These unfavorable impacts on our attritional loss ratio were largely offset by a favorable impact from changes in mix of business, as our growing lines of business generally have lower attritional loss ratios than the lines of business for which we have reduced our premium writings.

The 2025 combined ratio included $484.0 million of favorable development on prior accident years loss reserves compared to $454.9 million in 2024. The increase in favorable development was primarily attributable to more favorable development on our marine and energy product lines in 2025 compared to 2024, partially offset by less favorable development on our professional liability and general liability product lines in 2025 compared to 2024.

In 2025, favorable development was most significant within our marine and energy, general liability, workers' compensation, property, programs, and credit and surety insurance product lines. Favorable development in 2025 was net of $128.8 million, or two points, of adverse development on our run-off risk-managed directors and officers product lines.

In 2024, favorable development was most significant within our international professional liability product lines, as well as our property, general liability, marine and energy, programs, and credit and surety insurance product lines. Favorable development in 2024 was net of $176.9 million, or two points, of adverse development on our risk-managed directors and officers product lines that are now in run-off.

See note 11 of the notes to consolidated financial statements included under Item 8 for more information on the Markel Insurance segment's prior year loss reserve development.

The increase in the expense ratio in 2025 compared to 2024 was primarily attributable to higher personnel costs, including increased severance costs related to recent organizational changes, higher professional fees, and changes in mix of business. Many of the product lines and markets in which we are growing within our International division carry higher expense ratios and lower loss ratios than the rest of the segment. The expense ratio also reflects costs associated with our growth and expansion efforts in these targeted markets.

2024 compared to 2023

Excluding losses attributed to natural catastrophes, the decrease in the Markel Insurance segment combined ratio in 2024 compared to 2023 was primarily attributable to more favorable development on prior accident years loss reserves, partially offset by a higher expense ratio.

Excluding losses attributed to natural catastrophes, the modest increase in the current accident year loss ratio in 2024 compared to 2023 was primarily attributable higher attritional loss ratios across our U.S. product lines, driven largely by our professional liability and general liability product lines, largely offset by lower attritional loss ratios within our international product lines. In 2024, we increased our attritional loss ratios on certain product classes within our U.S. professional liability and general liability product lines in response to unfavorable loss development trends in recent years and to include an increase in the level of caution on our U.S. professional liability and general liability product lines.

The 2024 combined ratio included $454.9 million of favorable development on prior accident years loss reserves compared to $36.7 million in 2023. The increase in favorable development was primarily attributable to favorable development on our general liability product lines in 2024 compared to significant adverse development in 2023.

In 2023, favorable development was most significant on our international professional liability product lines, as well as our property, marine and energy, personal lines, and workers' compensation insurance product lines. Favorable development in 2023 was net of $326.8 million, or four points, of adverse development across our U.S. general liability and professional liability insurance product lines, as well as notable adverse development on our general liability and public entity reinsurance product lines.

See note 11 of the notes to consolidated financial statements included under Item 8 for more information on the Markel Insurance segment's prior year loss reserve development.

The increase in the expense ratio in 2024 compared to 2023 was primarily attributable to higher personnel costs, including profit sharing expenses and investments in underwriting talent within our international operations, as well as other general and administrative expenses, including investments in technology across our global operations to drive future growth and operational efficiencies. The increase was also partially attributable to general cost inflation trends outpacing premium growth, as a result of the underwriting actions taken on our U.S. general liability and professional liability product lines, as previously discussed.

U.S. Wholesale and Specialty

In 2025, the 4% decrease in gross premium volume and 6% decrease in earned premiums within the U.S. Wholesale and Specialty division were primarily due to the impact of exiting our risk-managed directors and officers product line in this division, partially offset by the impact of new business and more favorable rates within our general liability product lines. The U.S. Wholesale and Specialty division's combined ratio in 2025 decreased seven points, primarily due to favorable development on prior accident year loss reserves in 2025. Favorable development in 2025 was net of $108.3 million, or four points on the U.S. Wholesale and Specialty combined ratio, of adverse development on our run-off risk-managed directors and officers product line. In 2024, we experienced $139.6 million, or five points on the U.S. Wholesale and Specialty combined ratio, of adverse development on our risk-managed directors and officers product line that is now in run-off.

In 2024, the 6% decreases in gross premium volume and earned premiums within the U.S. Wholesale and Specialty division were primarily due to targeted underwriting actions, resulting in decreased writings within our brokerage contractors, brokerage excess and umbrella, and risk-managed excess casualty general liability products. The U.S. Wholesale and Specialty division's combined ratio in 2024 decreased four points, primarily due to minimal development on prior accident year loss reserves in 2024 compared to adverse development in 2023, partially offset by a higher current accident year loss ratio. Adverse development in 2023 was driven by $331.9 million, or 11 points on the U.S. Wholesale and Specialty combined ratio, of adverse development across the division's general liability and professional liability product lines.

10K - 45

Programs and Solutions

In 2025, the 8% increases in underwriting gross premium volume and earned premiums within the Programs and Solutions division were driven by more favorable rates and new business within our personal lines and programs product lines, partially offset by the impact of exiting our European risk-managed directors and officers product line. The significant growth in fronting gross premium volume was driven by expansion of our property catastrophe programs with Nephila. The Programs and Solutions division's combined ratio in 2025 increased four points due to the impact of a higher attritional loss ratio and higher expense ratio. The attritional loss ratio in 2025 was impacted by large losses within our credit and surety product line and increased attritional loss ratios on our personal umbrella product line.

In 2024, the 13% increase in gross premium volume and 5% increase in earned premiums within the Programs and Solutions division were primarily due to new business growth and more favorable rates within our personal lines and programs product lines. The significant growth in fronting gross premium volume was driven by expansion of our property catastrophe and specialty programs with Nephila.

International

In 2025, the 14% increase in gross premium volume and 12% increase in earned premiums within the International division were driven by increases on our professional liability and general liability product lines. The International division's combined ratio in 2025 increased six points primarily due to less favorable development on prior accident years loss reserves.

In 2024, the 6% increase in gross premium volume and 9% increase in earned premiums within the International division were primarily due to growth within our marine and energy and general liability product lines. The International division's combined ratio in 2024 decreased nine points due to a lower current accident year loss ratio and more favorable development on prior accident years loss reserves.

Global Reinsurance

In 2025, the 10% decrease in gross premium volume within the Global Reinsurance division was primarily due to non-renewals on exited lines and renewal decreases within our professional liability and general liability product lines. The Global Reinsurance division's combined ratio in 2025 increased three points due to a higher loss ratio. Adverse development in 2025 was driven by increases in prior accident years loss reserves within our general liability product lines, due to greater severity than originally expected across older accident years and increases to more recent accident years to incorporate our loss experience on the older accident years. We also increased the level of caution in our current accident year loss ratios on these general liability product lines based on the loss experience on these older accident years.

In 2024, the 8% increase in gross premium volume and 2% increase in earned premiums within the Global Reinsurance division were primarily due increases on renewals and new business within our professional liability and marine and energy product lines. The Global Reinsurance division's combined ratio in 2024 decreased one point due to less adverse development on prior accident years loss reserves, largely offset by a higher current accident year loss ratio.

Industrial

We measure the operating performance of our Industrial segment by its operating revenues and adjusted operating income. Adjusted operating income represents operating income before amortization of acquired intangible assets. We consolidate the results of the businesses in the Industrial segment on a one-month lag, with the exception of significant transactions or events that occur during the intervening period. The following table summarizes the operating performance of our Industrial segment.

10K - 47

2025 compared to 2024

The increase in operating revenues in 2025 reflected organic growth and a full-year contribution from our June 2024 Valor Environmental (Valor) acquisition. The Industrial segment results in 2024 included five months of results from Valor.

Organic revenue growth of our Industrial segment was 2% in 2025. Organic revenue growth is a non-GAAP financial measure. See "Non-GAAP Financial Measures" for additional details.

Organic revenue growth was primarily attributable to increased demand for our equipment leasing services within the wind energy market, as well as a combination of higher prices and sales volume for our services and products in the commercial and residential construction markets. These increases were partially offset by lower sales volume of our products within the transportation industry due to a down cycle in demand for the industry.

The decrease in adjusted operating income in 2025 was primarily attributable to lower margins, due to higher materials and labor costs, and lower revenues within our industrial products businesses, partially offset by the impact of higher revenues within our industrial services businesses.

2024 compared to 2023

The increase in operating revenues in 2024 reflected the contribution of our June 2024 Valor acquisition. Organic revenue growth of our Industrial segment was flat in 2024. Higher sales volume at many of our businesses in 2024 was offset by lower sales volume of our products within the transportation industry due to the start of a down cycle in demand for the industry. The decrease in adjusted operating income in 2024 was primarily attributable to lower margins, due to higher materials and labor costs.

Financial

We measure the operating performance of our Financial segment by its operating revenues and adjusted operating income. Adjusted operating income represents operating income before amortization of acquired intangible assets. The following table summarizes the operating performance of our Financial segment.


	Year Ended December 31,						2025 vs 2024 % Change		2024 vs 2023 % Change
(dollars in thousands)	2025		2024		2023
Operating revenues	$	736,964	$	593,313	$	553,133	24	%	7	%
Adjusted operating income (1)	$	326,572	$	262,082	$	260,235	25	%	1	%

(1) Adjusted operating income for the years ended December 31, 2025, 2024, and 2023 included $2.9 million, $58.1 million, and $71.5 million, respectively, from Markel CATCo Re Ltd. (MCRe), all of which was attributable to noncontrolling interests.

2025 compared to 2024

The increase in operating revenues in 2025 reflected strong organic growth, as well as the impact of $41.4 million of income related to our minority investment in Velocity Holdco LLC (Velocity) resulting from the sales of its managing general agent operations and insurance carrier in 2025.

Organic revenue growth of our Financial segment was 17% in 2025. Organic revenue growth was primarily attributable to the impact of performance fees earned in 2025 and a higher effective management fee rate for our insurance-linked securities investment management services, as well as higher premium volume within our program services and lender services offerings.

The increase in adjusted operating income in 2025 was driven by the impact of higher revenues, including the income related to our minority investment in Velocity, as previously discussed. These increases were partially offset by the impact in 2024 of $58.1 million of favorable loss development on the run-off of reinsurance contracts written by MCRe, all of which was attributable to noncontrolling interests.

10K - 48

2024 compared to 2023

The increase in operating revenues in 2024 reflected 8% organic growth. Revenue growth and organic revenue growth in 2024 were primarily attributable to the impact of higher premium volume within our program services and lender services offerings, as well as increased net investment income driven by a higher yield and higher average holdings of short-term investments.

Consumer and Other

We measure the operating performance of our Consumer and Other segment by its operating revenues and adjusted operating income. Adjusted operating income represents operating income before amortization of acquired intangible assets. We consolidate the results of the businesses in the Consumer and Other segment on a one-month lag, with the exception of significant transactions or events that occur during the intervening period. The following table summarizes the operating performance of our Consumer and Other segment.


	Year Ended December 31,						2025 vs 2024 % Change		2024 vs 2023 % Change
(dollars in thousands)	2025		2024		2023

Adjusted operating income	$	174,636	$	145,372	$	136,465	20	%	7	%

2025 compared to 2024

The increase in operating revenues in 2025 reflected the contribution from our acquisition of Education Partners International (EPI). Organic revenue growth of our Consumer and Other segment was 1% in 2025, primarily attributable to increased sales of ornamental plants driven by higher demand and prices. The increase in adjusted operating income was driven by the contribution from EPI.

2024 compared to 2023

The increase in operating revenues in 2024 reflected the contribution from an acquisition made by one of our businesses in the first quarter of 2024. Organic revenue growth of our Consumer and Other segment was 2% in 2024. Organic revenue growth was primarily attributable to higher home sales volume, partially offset by a modest decrease in demand for certain of our consumer products and our consulting services. The increase in adjusted operating income in 2024 was driven by the impact of higher revenues, as well as higher margins on sales of ornamental plants.

Consolidated Investment Results

We measure our investment performance by analyzing net investment income, which reflects the recurring interest and dividend earnings on our investment portfolio. See note 4(d) of the notes to consolidated financial statements included under Item 8 for details regarding the components of net investment income.

We also analyze net investment gains, which are primarily comprised of unrealized gains and losses on our equity portfolio. 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. 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 December 31, 2025, the fair value of our equity portfolio included cumulative unrealized gains of $8.9 billion.

The following table summarizes our consolidated investment performance. Investing results are attributed to our businesses based on the subsidiary that holds the investments.


	Year Ended December 31,

Ten-year annual return	13.5		%	12.1		%	11.9		%
Twenty-year annual return	11.0		%	10.5		%	10.2		%

(1) Yield reflects the applicable 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.

2025 compared to 2024

The 5% increase in net investment income in 2025 was primarily driven by higher interest income on fixed maturity securities due to a higher yield and higher average holdings. These increases were partially offset by lower interest income on our short-term investments due to lower average short-term investment holdings and lower short-term interest rates. Proceeds from our May 2024 senior debt offering, which had been held in short-term investments, were used to redeem our preferred shares in the second quarter of 2025 resulting in lower average holdings.

2024 compared to 2023

The 25% increase in net investment income in 2024 was primarily driven by higher interest income on fixed maturity securities due to a higher yield and higher average holdings, as well as higher yields on cash and short-term investments.

The following tables summarize the composition of our invested assets by segment. We hold investments across our operating businesses and at our holding company, with the majority of our investments held at our Markel Insurance business in support of its underwriting activities. Invested assets and the associated net investment income at our other reportable segments are primarily attributable to our Financial segment. Markel Insurance has also provided loans to a corporate subsidiary to fund certain non-insurance acquisitions. We evaluate these loan receivables similarly to invested assets held by Markel Insurance.

Additionally, one of our corporate subsidiaries may, from time to time, provide loans to our operating businesses to fund strategic growth investments and projects. These intercompany loans are presented in the tables below but are eliminated in consolidation.

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


	Year Ended December 31,

Effective tax rate	21		%	22		%	21		%

Interest Expense

The increase in interest expense in 2025 was primarily attributable to the issuance of our $600 million 6% unsecured senior notes in May 2024, partially offset by a decrease in interest expense on revolving lines of credit at certain of our operating businesses. The increase in interest expense in 2024 was primarily attributable to the issuance of our senior notes in May 2024. See note 14 of the notes to consolidated financial statements included under Item 8 for further details regarding our senior long-term debt.

Net Foreign Exchange Gains and Losses

Net foreign exchange gains and losses are primarily due to the remeasurement of our foreign currency denominated insurance loss reserves to the U.S. Dollar. The predominant foreign currencies of these loss reserves are the Euro and the British Pound. The U.S. Dollar weakened against the Euro and British Pound in 2025 and 2023, while it strengthened against these currencies during 2024.

Our exposure to foreign currency exchange rates is largely hedged through our available-for-sale investment portfolio, where we hold securities that generally match the currencies of our loss reserves. We also purchase foreign currency forward contracts to further manage unmatched foreign currency exposures. 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 gains of $204.6 million in 2025, losses of $93.2 million in 2024, and gains of $74.0 million in 2023.

See "Foreign Currency Exchange Rate Risk" under Item 7A Quantitative and Qualitative Disclosures About Market Risk for additional information about how we manage foreign currency exchange rate risk.

Income Taxes

See note 15 of the notes to consolidated financial statements included under Item 8 for further details on our income taxes.

On July 4, 2025, the U.S. enacted legislation known as the One Big Beautiful Bill Act of 2025 (the OBBB Act) which makes permanent many of the tax provisions enacted in 2017 as part of the Tax Cuts and Jobs Act that were set to expire at the end of 2025. In addition, the OBBB Act makes changes to certain U.S. corporate tax provisions, most of which are not effective until 2026. The OBBB Act did not have a material impact on our results of operations, financial condition, or cash flows.

Other Comprehensive Income (Loss) to Shareholders

The following table summarizes the components of other comprehensive income (loss) to shareholders.


	Year Ended December 31,
(dollars in thousands)	2025		2024		2023
Change in net unrealized losses on available-for-sale investments, net of taxes	$	490,350	$	(130,295)	$	306,903

Other comprehensive income (loss) to shareholders	$	507,622	$	(138,872)	$	289,284

The change in net unrealized losses on available-for-sale investments in any given period is attributable to changes in the fair value of our fixed maturity portfolio due to changes in interest rates during the period, and, to a lesser extent, changes in foreign currency exchange rates, as previously discussed. See note 20 of the notes to consolidated financial statements included under Item 8 for further details on the components of other comprehensive income.

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 19% and 20% at December 31, 2025 and 2024, respectively, both of which are within the range of our target capital structure.

Holding Company

Our holding company, Markel Group Inc, had $4.4 billion and $4.3 billion of invested assets at December 31, 2025 and December 31, 2024, respectively. See Schedule II included under Item 8 for condensed financial information of our holding company.

Capital Allocation

After satisfying our interest and principal obligations on our senior long-term debt and any other corporate obligations, capital at Markel Group is available to, among other things, allocate to our existing businesses, complete acquisitions, invest in public equity securities, or repurchase shares of our common stock.

We have a share repurchase program, authorized by our Board of Directors, that provides for the repurchase of up to $2 billion of common stock. As of December 31, 2025, $1.5 billion remained available for repurchases under the program. The program has no expiration date but may be terminated by the Board of Directors at any time.

We may seek to prepay, retire, or repurchase our outstanding senior notes, 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.

Capital Sources

We have access to various capital sources, including dividends from our subsidiaries, holding company invested assets, undrawn capacity under our revolving corporate 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 terms of future financings will depend on a variety of factors. See the "Liquidity and Access to Capital" risk factors under Item 1A Risk Factors for more discussion regarding our access to capital.

Dividends from our Subsidiaries

In 2025, our holding company received $794.2 million of dividends from its subsidiaries, including $634.7 million from Markel Insurance. In 2024, our holding company received $575.0 million of dividends from its subsidiaries, including $360.0 million from Markel Insurance.

10K - 54

Our holding company has historically relied on dividends from its insurance subsidiaries as an important source of capital to meet its obligations. Under the insurance laws of the various states in which our domestic insurance subsidiaries are incorporated, an insurer is restricted in the amount of dividends it may pay without prior approval of regulatory authorities. There are also regulatory restrictions on the amount of dividends that certain of our foreign insurance subsidiaries may pay based on applicable laws in their respective jurisdictions. At December 31, 2025, our domestic insurance subsidiaries and Markel Bermuda Limited could pay ordinary dividends of $1.4 billion during the following twelve months under these laws.

Corporate Credit Facility

We maintain a corporate revolving credit facility, which provides up to $300 million of capacity for future acquisitions, investments, and stock repurchases, as well as other working capital and general corporate purposes. At our discretion, up to $200 million of the total capacity may be used for letters of credit. We may increase the capacity of the facility by up to $200 million subject to obtaining commitments for the increase and certain other terms and conditions. Markel Group guarantees the obligations under the facility of the insurance subsidiaries that are also parties to the credit agreement. This facility expires in June 2028. As of December 31, 2025 and 2024, there were no borrowings outstanding under this revolving credit facility.

We were in compliance with all covenants contained in our corporate revolving credit facility at December 31, 2025. To the extent that we are not in compliance with our covenants, access to the revolving credit facility could be restricted. While we believe this to be unlikely, the inability to access the revolving credit facility could adversely affect our liquidity. See note 14 of the notes to consolidated financial statements included under Item 8 for further discussion of our corporate revolving credit facility.

Cash Flows and Invested Assets

Invested Assets

Invested assets were $37.4 billion at December 31, 2025 compared to $34.2 billion at December 31, 2024, reflecting an increase of 9% in 2025. For further details on the composition of our invested assets, see "Consolidated Investment Results." The increase was primarily attributable to net cash provided by operating activities and an increase in the fair value of our investment portfolio.

Operating Cash Flows

Net cash provided by operating activities was $2.8 billion in 2025 compared to $2.6 billion in 2024, reflecting growth within our Financial segment and higher cash flows from investments, primarily within our Markel Insurance segment.

Net cash provided by operating activities was $2.6 billion in 2024 compared to $2.8 billion in 2023. The decrease was primarily due to lower cash flows from our Industrial and Consumer and Other segments. Within our Markel Insurance segment, higher net claims payments were largely offset by higher net premium collections and higher cash flows from investments.

Investing Cash Flows

Net cash used by investing activities was $1.2 billion in 2025 and included net purchases of fixed maturity securities and equity securities of $1.4 billion and $142.9 million, respectively, and net sales of short-term investments of $578.0 million.

Net cash used by investing activities was $2.4 billion in 2024 and included net purchases of fixed maturity securities and equity securities of $1.5 billion and $394.8 million, respectively, and net sales of short-term investments of $152.0 million, as well as investments in Valor and EPI.

Net cash used by investing activities was $2.7 billion in 2023 and included net purchases of fixed maturity securities and equity securities of $2.2 billion and $339.7 million, respectively, and net sales of short-term investments of $202.9 million.

Cash flow 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.

10K - 55

Financing Cash Flows

Net cash used by financing activities was $1.2 billion, $297.9 million, and $999.7 million in 2025, 2024, and 2023, respectively. Cash of $429.5 million, $572.7 million, and $445.5 million was used to repurchase shares of our common stock during 2025, 2024, and 2023, respectively. In 2024, we received net proceeds of $592.6 million from the issuance of senior notes in May 2024. In 2025, these proceeds were used to redeem in full our outstanding preferred shares for $600.0 million. In 2023, we used $250.0 million to retire our senior notes due March 30, 2023. Financing activities in 2025, 2024, and 2023 also reflected borrowings and repayments at certain of our operating businesses, primarily on revolving lines of credit.

Cash Obligations

As of December 31, 2025, our primary contractual cash obligations were unpaid losses and loss adjustment expenses, senior long-term debt and other debt and related interest payments, life and annuity benefits, lease liabilities, and purchase obligations. These cash obligations, as presented in the following table, represent our estimate of total future cash payments and may differ from the corresponding liabilities on our consolidated balance sheet due to present value discounts and other adjustments required for presentation in accordance with U.S. GAAP. The following table summarizes our estimated contractual cash obligations at December 31, 2025 and the estimated amount expected to be paid in 2026.


(dollars in thousands)	Total cash obligations as of December 31, 2025		Cash obligations due in less than 1 year
Unpaid losses and loss adjustment expenses (1)	$	31,048,930	$	6,759,079
Senior long-term debt and other debt (2)	$	4,353,718	$	54,388
Interest payments on senior long-term debt and other debt (3)	$	3,944,617	$	199,624
Lease liabilities (4)	$	872,123	$	140,415
Life and annuity benefits (5)	$	800,717	$	68,264
Purchase obligations (6)	$	413,685	$	190,894

(1) The actual cash payments for settled claims will vary, possibly significantly, from these estimates. As of December 31, 2025, the average duration of our reserves for unpaid losses and loss adjustment expenses was 4.1 years. See note 11 of the notes to consolidated financial statements included under Item 8 for further details on our loss reserve estimates.

(2) See note 14 of the notes to consolidated financial statements included under Item 8 for further details on the scheduled maturity of principal payments on our senior long-term debt and other debt.

(3) Interest expense is accrued in the period incurred and therefore, only a portion of the future interest payments presented in this table represents a liability on our consolidated balance sheet as of December 31, 2025.

(4) See note 9 of the notes to consolidated financial statements included under Item 8 for further details on our operating lease obligations and the expected timing of future payments.

(5) There is inherent uncertainty in the process of estimating the timing of payments for life and annuity benefits and actual cash payments for settled contracts could vary significantly from these estimates. We expect $536.2 million of our cash obligation for life and annuity benefits to be paid beyond five years. See note 1 and note 13 of the notes to consolidated financial statements included under Item 8 for further details on our estimates for life and annuity benefit reserves.

(6) Purchase obligations are primarily related to open purchase order commitments with subcontractors and suppliers.

Our redeemable noncontrolling interests represent a potential contractual cash obligation if put options are exercised by the other equity interest holders. Of the total redeemable noncontrolling interests of $506.1 million at December 31, 2025, $122.1 million is available for redemption in 2026 at the option of the equity holders, with the remainder becoming redeemable between 2027 and 2033. We may also exercise our call options to purchase redeemable noncontrolling interests, at our discretion, as a capital allocation decision.

Restricted Assets and Capital

At December 31, 2025, we had $5.4 billion of invested assets held in trust or on deposit for the benefit of policyholders or ceding companies or to support underwriting activities. We have also pledged invested assets totaling $414.8 million as security for letters of credit that have been issued by various banks on our behalf. These invested assets and the related liabilities are included on our consolidated balance sheet. Additionally, our holding company has pledged equity securities with a fair value of $120.8 million at December 31, 2025 as collateral for a parental guarantee for an intercompany subsidiary loan. These equity securities are included on our consolidated balance sheet; however, the liability associated with the intercompany loan is eliminated in consolidation. See note 4(f) of the notes to consolidated financial statements included under Item 8 for further discussion of restrictions over our invested assets.

10K - 56

Our insurance subsidiaries require capital to support premium writings, and we remain committed to maintaining adequate capital and surplus at each of our insurance subsidiaries. The National Association of Insurance Commissioners (NAIC) developed a model law and risk-based capital formula designed to help regulators identify domestic property and casualty insurers that may be inadequately capitalized. Under the NAIC's requirements, a domestic insurer must maintain total capital and surplus above a calculated threshold or face varying levels of regulatory action. Capital adequacy of our foreign insurance subsidiaries is regulated by applicable laws of the United Kingdom, Bermuda, and Germany. At December 31, 2025, the capital and surplus of each of our insurance subsidiaries significantly exceeded the amount of statutory capital and surplus necessary to satisfy regulatory requirements.

Non-GAAP Financial Measures

Markel Group utilizes certain non-GAAP measures that we believe enhance the understanding of our performance. These measures should not be viewed as a substitute for measures determined in accordance with U.S. GAAP.

Consolidated Adjusted Operating Income and Adjusted Operating Income Per Share

Consolidated adjusted operating income and adjusted operating income per share, both of which exclude net investment gains and losses, amortization of acquired intangible assets, and impairment of goodwill, are non-GAAP financial measures. We believe adjusted operating income is generally an accurate representation of the operating performance of our businesses in our periodic results.

Net investment gains and losses are predominantly derived from our investments in publicly traded equity securities and include significant unrealized gains and losses from market value movements. We believe that net investment gains and losses, whether realized from sales or unrealized from market value movements, are distortive in understanding the short-term operating performance of our businesses. We do not view amortization of intangible assets and impairment of goodwill, which arise from purchase accounting for acquisitions, as ongoing costs of operating our businesses, and therefore exclude those amounts from our adjusted operating income metrics.

The following table reconciles operating income to adjusted operating income on both a consolidated and per share basis.

Combined Ratio and Current Accident Year Loss Ratio, Excluding Current Year Catastrophe Events

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.

10K - 57

When analyzing our loss ratio, we typically evaluate losses and loss adjustment expenses attributable to the current accident year separately 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 the current accident year loss ratio that excludes prior accident year reserve development is helpful in most cases since it provides more insight into estimates of current underwriting performance and excludes changes in estimates related to prior year loss reserves.

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 on these ratios. We believe these adjusted measures, which are non‑GAAP measures, provide financial statement users with a better understanding of the significant factors that comprise our underwriting results and how management evaluates underwriting performance.

When analyzing our combined ratio, we exclude current accident year losses and loss adjustment expenses attributed to natural catastrophes and certain other significant, infrequent loss events. Gross and ceded losses for certain events may also result in receipt or payment of reinstatement premiums, which, if significant, may also be excluded when analyzing our combined ratio. Due to the unique characteristics of these events, there is inherent variability as to the timing and amount of the loss, which cannot be predicted in advance. We believe measures that exclude the effects of such events are meaningful to understand

the underlying trends and variability in our underwriting results that may be obscured by these items.

We also analyze our current accident year loss ratio excluding losses and loss adjustment expenses attributable to catastrophes and other significant, infrequent loss events. The current accident year loss ratio excluding the impact of catastrophes and other significant, infrequent loss events is commonly referred to as an attritional loss ratio within the property and casualty insurance industry.

The components of Markel Insurance's combined ratios, including these non-GAAP measures, are included in "Markel Insurance."

Organic Revenue Growth

Organic revenue growth is a non-GAAP measure. We believe organic revenue growth is a meaningful measure as it provides growth in comparable revenues from period-to-period by adjusting for the impact of acquisitions and dispositions. For acquisitions and dispositions, the calculation of organic revenue growth excludes the revenue of the business from the two periods being compared unless our consolidated results include a full period of revenue from the business for both periods. The following table reconciles revenue growth to organic revenue growth.

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. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements. Our accounts with accounting policies that involve critical accounting estimates are unpaid losses and loss adjustment expenses and goodwill and intangible assets.

Unpaid Losses and Loss Adjustment Expenses

We accrue liabilities for unpaid losses and loss adjustment expenses based upon estimates of the ultimate amounts payable. We maintain reserves for specific claims incurred and reported (case reserves) and reserves for claims incurred but not reported (IBNR reserves). IBNR reserves are calculated by subtracting paid losses and loss adjustment expenses and case reserves from estimated ultimate losses and loss adjustment expenses. The liability for unpaid losses and loss adjustment expenses includes significant estimates for incurred but not reported claims.

The following table summarizes case reserves and IBNR reserves. Our consolidated balance sheets do not include reserves for losses and loss adjustment expenses attributed to unconsolidated subsidiaries or affiliates that we manage through our Nephila insurance-linked securities operations.


	December 31,
(dollars in thousands)	2025		2024
Case reserves	$	9,527,005	$	7,717,107
IBNR reserves	21,330,448		18,915,987
Total	$	30,857,453	$	26,633,094

Each quarter, our actuaries prepare estimates of the ultimate liability for unpaid losses and loss adjustment expenses based on established actuarial methods. Management reviews these estimates, supplements the actuarial analyses with information provided by claims, underwriting, and other operational personnel and determines its best estimate of loss reserves, which is recorded on our consolidated financial statements. Our procedures for determining the adequacy of loss reserves at the end of the year are substantially similar to the procedures applied at the end of each interim period. Any adjustments to reserves resulting from our interim or year-end reviews, including changes in estimates, are recorded as a component of losses and loss adjustment expenses in the period of the change.

Fronting

Unpaid losses and loss adjustment expenses attributable to fronting activities were $8.8 billion and $6.5 billion as of December 31, 2025 and 2024, respectively, and are attributed to our State National and Markel Insurance businesses. Substantially all of the fronted premiums are ceded, resulting in reinsurance recoverables on unpaid losses for this business of $8.8 billion and $6.5 billion as of December 31, 2025 and 2024, respectively.

Case reserves for fronted business are generally established based on reports received from the general agents or reinsurers with whom we do business. Our actuaries review the case loss reserve data received for sufficiency and consistency with historical data and other programs we write that have similar characteristics. Ultimate losses and loss adjustment expenses are calculated using either our program experience or, where the program data is not credible, industry experience for similar products or lines of business.

Underwriting

Unpaid losses and loss adjustment expenses attributable to underwriting activities were $22.1 billion and $20.1 billion as of December 31, 2025 and 2024, respectively. Reinsurance recoverables on unpaid losses for our underwriting activities was $5.4 billion and $4.6 billion as of December 31, 2025 and 2024, respectively. Our underwriting activities are primarily attributable to our Markel Insurance business.

For insurance contracts, we are generally notified of insured losses by our insureds, their brokers, or the primary insurer in instances in which we participate in excess layers of insured losses on a contract. Based on this information, we establish case

10K - 59

reserves by estimating the expected ultimate losses from the claim, including any administrative or legal costs associated with settling the claim and other third-party costs. For reinsurance contracts, case reserves are generally established based on reports received from ceding companies or their brokers. For excess of loss contracts, we are typically notified of insurance losses on specific contracts and record a case reserve for the estimated expected ultimate losses from the claim. For quota share contracts, we typically receive aggregated claims information and record a case reserve based on that information. As with insurance contracts, we evaluate this information and estimate the expected ultimate losses.

There is a time lag between when a loss event occurs and when it is reported to us, and some claims may not be reported for many years. The actuarial methods that we use to estimate ultimate losses have been designed to address the lag in loss reporting as well as the delay in obtaining information that would allow us to more accurately estimate future payments. The reporting lag can be more pronounced in our reinsurance contracts than in our insurance contracts due to a time lag between cedents establishing case reserves or re-estimating their reserves and notifying us of those new or revised case reserves. There may also be a more pronounced reporting lag on insurance contracts for which we are not the primary insurer and participate only in excess layers of loss. Based on the experience of our actuaries and management, we select loss development factors and trending techniques to mitigate the difficulties caused by reporting lags. At least annually, we evaluate our loss development factors and trending assumptions using our own loss data, as well as cedent-specific and industry data, and update them as needed.

Our liabilities for unpaid losses and loss adjustment expenses can generally be categorized into two distinct groups, short-tail business and long-tail business. Short-tail business refers to lines of business, such as property, accident and health, automobile, watercraft, and marine hull exposures, for which losses are usually known and paid shortly after the loss actually occurs. Long-tail business refers to lines of business for which specific losses take much longer to emerge and may not be known and reported for some time. Given the time frame over which long-tail exposures are ultimately settled, there is greater uncertainty of the ultimate losses in these lines than in short-tail lines of business.

Our long-tail coverages consist of most casualty lines, including professional liability, products liability, general and excess liability, and excess and umbrella exposures, as well as workers' compensation insurance. Some factors that contribute to the uncertainty and volatility of long-tail business, and thus require a significant degree of judgment in the reserving process, include the effects of unanticipated levels of economic inflation, the impact of social inflation, the inherent uncertainty as to the length of reporting and payment development patterns, and the possibility of judicial interpretations or legislative changes that might impact future loss experience relative to prior loss experience.

Actuarial Methods and Analysis

In establishing our liabilities for unpaid losses and loss adjustment expenses, our actuaries estimate an ultimate loss ratio, by accident year or underwriting year, for each of our product lines with input from our underwriting and claims personnel. For product lines in our international insurance and run-off reinsurance operations, where loss reserves are established on an underwriting year basis, we have developed a methodology to convert from underwriting year to accident year for financial reporting purposes.

In estimating an ultimate loss ratio for a particular line of business, our actuaries may use one or more actuarial reserving methods and select from these a single point estimate. To varying degrees, these methods include detailed statistical analysis of past claim reporting, settlement activity, claim frequency and severity, policyholder loss experience, industry loss experience, and changes in market and economic conditions, policy forms, and exposures.

The actuarial methods we use include Initial Expected Loss Ratio Method, Paid Loss Development, Incurred Loss Development, Bornhuetter-Ferguson Paid Loss Development, Bornhuetter-Ferguson Incurred Loss Development, and Frequency/Severity. There are certain instances when these traditional actuarial methods may not be appropriate for estimating unpaid losses and loss adjustment expenses. In these instances, we may employ other actuarial methods.

Each actuarial method has its own set of assumptions and its own strengths and limitations. Our actuaries select the reserving methods that they believe will produce the most reliable estimates for the class of business being evaluated. Greater judgment may be required when we introduce new product lines or when there have been changes in claims handling practices, as the statistical data available may be insufficient. In these instances, we may rely upon assumptions applied to similar lines of business, rely more heavily on industry experience, take into account changes in underwriting guidelines and risk selection, or review the impact of changes in claims reserving practices with claims personnel. Greater judgment also may be required for product lines that experience a low frequency of high severity claims, particularly when we are reliant on third-party case reserve estimates and claims handling practices. In these instances, we may perform detailed claims reviews, analyzing the

10K - 60

characteristics of each individual claim, with input from both actuarial and claims personnel to assess the adequacy of the case and IBNR reserves on the underlying product line. While we use our best judgment in establishing our estimate for loss reserves, applying different assumptions and variables could lead to significantly different loss reserve estimates.

A key assumption in most actuarial analyses is that past development patterns will repeat themselves in the future, absent a significant change in internal or external factors that influence the ultimate cost of our unpaid losses and loss adjustment expenses. Our estimates reflect implicit and explicit assumptions regarding the potential effects of external factors, including economic and social inflation, judicial decisions, changes in law, general economic conditions, and recent trends in these factors. Our actuarial analyses are based on statistical analysis but also consist of reviewing internal factors that are difficult to analyze statistically, including changes in underwriting and claims handling practices. Where we act as a reinsurer or participate only in excess layers of insured losses, the timing and amount of information reported about underlying claims are in the control of third parties. This can also affect estimates and require re-estimation as new information becomes available.

We cannot estimate losses from widespread catastrophic events, such as hurricanes, earthquakes, pandemics, and wars, using the traditional actuarial methods previously described. In the initial months after a catastrophic event occurs, our underwriting, claims, and actuarial personnel estimate losses and loss adjustment expenses based on claims received to date, analysis of exposures in the impacted areas, industry loss estimates and output from industry, broker and proprietary models, as well as analysis of our ceded reinsurance contracts. The availability of data from these procedures varies depending on the timing of the event relative to the point at which we develop our estimate. We also consider loss experience on historical events that may have similar characteristics to the underlying event and current market conditions. In the period shortly after an event occurs, more weight is put on modeling and industry estimates, whereas with the passage of time, greater reliance is placed on incurred claims data, individual contract exposures and historical claim patterns. Due to the inherent uncertainty in estimating such losses, these estimates are subject to variability, which increases with the severity and complexity of the underlying event. As additional claims are reported and paid, and industry loss estimates are revised, we incorporate this new information into our analysis and adjust our estimate of ultimate losses and loss adjustment expenses as appropriate.

Management's Best Estimate

Loss reserves are established at management's best estimate, which is developed using the actuarially calculated point estimate as the starting point. The actuarial point estimate represents our actuaries' best estimate of the most likely amount that will ultimately be paid to settle the losses that have occurred at a particular point in time. Similarly, the estimate for ceded losses is calculated based on the ultimate gross loss amount expected to be paid, as well as the frequency and severity of the underlying claims, which ultimately determines coverage under the applicable ceded reinsurance contracts. Therefore, ceded loss estimates are subject to many of the same judgments and assumptions as the gross loss estimates.

In some cases, actuarial analyses, which are generally based on statistical analysis, cannot fully incorporate all of the subjective factors that affect development of losses. In other cases, management's perspective of these more subjective factors may differ from the actuarial perspective. Subjective factors influencing the development of management's best estimate include: the credibility and timeliness of claims and loss information received from cedents and other third parties; and the impacts of economic and social inflation, judicial decisions, changes in law, changes in underwriting or claims handling practices, general economic conditions, the risk of moral hazard and other current and developing trends within the insurance and reinsurance markets, including the effects of competition.

In developing its best estimate of loss reserves, management's philosophy is to establish loss reserves that are more likely to be redundant rather than deficient, and therefore, will ultimately prove to be adequate. Management's approach to establishing loss reserves generally results in loss reserves that exceed the calculated actuarial point estimate.

Management also considers the range, or variability, of reasonably possible loss outcomes determined by our actuaries when establishing its best estimate for loss reserves. The actuarial ranges represent our actuaries' estimate of a likely lowest amount and likely highest amount that could ultimately be paid to settle the losses that have occurred at a particular point in time. The range determinations are based on estimates and actuarial judgements and are intended to encompass reasonably likely changes in one or more of the factors that were used to determine the point estimates. Using statistical models, our actuaries establish a range of reasonable reserve estimates.

The net loss reserves held for our underwriting operations at December 31, 2025 were $16.7 billion. The actuarially established low and high ends of a range of reasonable net reserve estimates at December 31, 2025 for our underwriting operations was $13.6 billion and $17.8 billion, respectively.

10K - 61

Undue reliance should not be placed on this range of estimates as they are only one of many points of reference used by management to determine its best estimate of ultimate losses. Further, actuarial ranges may not be a true reflection of the potential variability between loss reserves estimated at the balance sheet date and the ultimate cost of settling claims. Similar to the development of our estimate of ultimate losses, actuarial ranges are developed based on known events as of the valuation date, while ultimate paid losses are subject to events and circumstances that are unknown as of the valuation date.

Changes in Estimates

Our ultimate liability may be greater or less than current reserves. Changes in our estimated ultimate liability for loss reserves generally occur as a result of the emergence, or lack thereof, of unanticipated loss activity, the completion of specific actuarial or claims studies, or changes in internal or external factors. We closely monitor new information on reported claims and use statistical analyses prepared by our actuaries to evaluate the adequacy of our recorded reserves. We are required to exercise considerable judgment when assessing the relative credibility of loss development trends. Loss frequency and loss severity are two key measures of loss activity that often result in adjustments to actuarial assumptions relative to ultimate loss reserve estimates. Additionally, our estimate of ceded losses and loss adjustment expenses are impacted by these same factors, and for our U.S. casualty reinsurance treaty, our estimate of ceded losses and loss adjustment expenses is also impacted by assumptions around reinsurance coverage.

Consistent with our reserving philosophy, if new information or trends indicate an increase in frequency or severity of claims in excess of what we initially anticipated, we generally respond quickly and increase loss reserves. If, however, frequency or severity trends are more favorable than initially anticipated, we often wait to reduce our loss reserves until we can evaluate experience in additional periods to confirm the credibility of the trend. In addition, for long-tail lines of business, trends develop over longer periods of time, and as a result, we give credibility to favorable trends more slowly than for short-tail or less volatile lines of business.

Our underwriting results included $488.3 million, $455.3 million, and $38.6 million of net favorable development on prior years loss reserves in 2025, 2024, and 2023, respectively, which represented 3.1%, 3.1%, and 0.3%, respectively, of beginning of year net reserves. In 2025 and 2024, we had net favorable development across most of our major product lines, however, certain lines within our U.S. professional liability product lines experienced adverse development in both years. Favorable development in 2023 included significant favorable development across several product lines, largely offset by adverse development on certain long-tail U.S. general liability and professional liability product lines.

Changes in prior years loss reserves, including the trends and factors that impacted loss reserve development in 2025, 2024, and 2023, as well as further details regarding the historical development of reserves for losses and loss adjustment expenses are discussed in further detail in note 11 of the notes to consolidated financial statements included under Item 8. Our product lines with net favorable development in these years benefited from the re-estimation of our ultimate incurred losses following more favorable loss experience compared to our previous expectations. As previously discussed, loss reserves are recorded at management's best estimate, which is higher than the corresponding actuarially calculated point estimate. As actual loss experience continued to be more favorable than previously anticipated, it became more likely that the ultimate losses would prove to be lower than previously estimated. Management gave greater credibility to the favorable trends observed by our actuaries and, upon incorporating these favorable trends into our best estimate, we reduced prior years loss reserves accordingly.

Favorable development in each of these years was offset, to varying degrees, by adverse development on certain long-tail U.S. product lines, with adverse development in 2023 being the most significant. In 2023, unfavorable claims and loss trends experienced on our U.S. general liability and professional liability product lines disrupted the development of historic favorable claims trends, reflecting broader market conditions, including the effects of economic and social inflation, and resulted in significant adverse loss development across a number of sub-classes. In 2024, certain of our U.S. professional liability product lines continued to experience many of these same trends, while the U.S. general liability product lines began to stabilize. In 2025, while certain of our U.S. professional liability product lines also began to stabilize, our run-off risk-managed directors and officers product lines experienced notable adverse development.

As previously discussed, management's philosophy is to establish loss reserves that are more likely to be redundant rather than deficient. Our consistent application of this philosophy is best illustrated over long periods of time, whereby reserves have developed favorably for each of the past 21 years. While we believe it is likely that there will be additional favorable development in 2026, we caution readers not to place undue reliance on this favorable trend.

10K - 62

In assessing the likelihood of whether the trends previously discussed will continue and whether other trends may develop, we believe that a reasonably likely movement in prior years loss reserves during 2026 would be a range of favorable development of up to 5%, or $800 million, of December 31, 2025 net loss reserves.

Goodwill and Intangible Assets

Our consolidated balance sheet as of December 31, 2025 included goodwill and intangible assets of $4.4 billion as follows:


	December 31, 2025
(dollars in millions)	Markel Insurance		Industrial		Financial		Consumer and Other		Corporate		Total
Goodwill	$	1,025.4	$	855.3	$	490.3	$	451.1	$	—	$	2,822.1
Intangible assets	219.1		526.3		435.9		355.6		6.0		1,543.0
Total	$	1,244.5	$	1,381.6	$	926.2	$	806.7	$	6.0	$	4,365.1

Goodwill and intangible assets are recorded as a result of business acquisitions. Goodwill represents the excess of the amount paid to acquire a business over the net fair value of assets acquired and liabilities assumed at the date of acquisition. Indefinite-lived and other intangible assets are recorded at fair value as of the acquisition date. The determination of the fair value of certain assets acquired, including goodwill and intangible assets, and liabilities assumed involves significant judgment and the use of valuation models and other estimates, which require assumptions that are inherently subjective. During the year ended December 31, 2025 and 2024, we recorded $349.9 million and $167.5 million, respectively, of goodwill and intangible assets in connection with acquisitions.

Intangible assets with definite lives are reviewed for impairment when events or circumstances indicate that their carrying value may not be recoverable. Goodwill and indefinite-lived intangible assets are tested for impairment annually, or when events or circumstances indicate that their carrying value may not be recoverable. As a result of our segment changes in 2025, we reassessed our reporting units. For any changes in reporting units that required a reallocation of goodwill, we tested goodwill for impairment immediately prior to the change in reporting units and determined that there was no impairment of goodwill.

A significant amount of judgment is required in performing impairment tests, including the optional assessment of qualitative factors for the annual impairment test, which is used to determine whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. This assessment serves as a basis for determining whether it is necessary to perform a quantitative impairment test.

We completed our annual tests for impairment as of October 1, 2025 based upon results of operations through September 30, 2025. We elected to perform a quantitative assessment for one of our reporting units and a qualitative assessment for all of our other reporting units.

When performing our quantitative assessment, we used an income approach based on a discounted cash flow model to estimate the fair value of the reporting unit. The cash flow projections included management's best estimate of future growth and margins. The discount rate used was primarily based on a capital asset pricing model. Based on the results of our quantitative assessment, the estimated fair value of the reporting unit exceeded its carrying value.

When performing our qualitative assessments, we considered macroeconomic factors such as industry conditions and market conditions. We also considered reporting unit-specific events, actual financial performance versus expectations and management's future business expectations, as well as the amount by which the fair value of the reporting unit exceeded its carrying value at the date of the last quantitative assessment. As part of our qualitative assessment of recently acquired reporting units with material goodwill, we considered the fact that the businesses had been acquired in orderly transactions between market participants, and our purchase price represented fair value at acquisition. We considered similar factors to determine if there were any indicators requiring an assessment of the recoverability of our definite lived intangible assets and concluded there were not. For recent acquisitions for which we elected to perform a qualitative assessment, there were no events since acquisition that had a significant adverse impact on the fair value of these reporting units through the assessment date. Based on the results of our qualitative assessments, we believe it is more likely than not that the fair value of each of the assessed reporting units exceeded its respective carrying amount.

Based on the results of our assessments, there were no impairments of goodwill in 2025, and none of our reporting units are at risk of a material impairment of goodwill. Additionally, there were no significant events or changes in circumstances

10K - 63

impacting our reporting units between the assessment date and December 31, 2025. However, deterioration of market conditions related to the general economy or the specific industries in which we operate, a sustained trend of weaker than anticipated financial performance within a reporting unit beyond that which we considered or included in our assessments, or an increase in the market-based weighted average cost of capital, among other factors, could impact the impairment analysis and may result in future goodwill or intangible asset impairment charges.

See the risk factor titled "Impairment in the value of our goodwill or intangible assets could have a material adverse effect on our operating results and financial condition" within Item 1A Risk Factors for further discussion of risks associated with our goodwill and intangible assets.

Item 7A. 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.

Our fixed maturity securities and equity securities are recorded at fair value. See note 5 of the notes to consolidated financial statements included under Item 8 for details regarding the fair value measurement of our fixed maturity and equity securities.

10K - 66

Equity Price Risk

We make investments in equity securities, which have historically produced higher long-term returns relative to fixed maturity securities, with capital that is allocated for such purposes. We intend to hold these investments over the long term and focus on long-term return on equity securities, understanding that gains or losses on investments may fluctuate from one period to the next. Changes in the fair value of equity securities are recognized in net income.

At December 31, 2025, our equity portfolio was concentrated in terms of the number of issuers and industries. Such concentrations can lead to higher levels of volatility. At December 31, 2025, our ten largest equity holdings represented $5.9 billion, or 45%, of the equity portfolio. Investments in the property and casualty insurance industry represented $2.3 billion, or 17%, of our equity portfolio at December 31, 2025 and included a $1.6 billion investment in the common stock of Berkshire Hathaway Inc., a company whose subsidiaries engage in a number of diverse business activities in addition to insurance. We have investment guidelines that set limits on the equity holdings of our insurance subsidiaries.

The following table summarizes our equity price risk and shows the effect of a hypothetical 35% increase or decrease in market prices as of December 31, 2025 and 2024. The selected hypothetical changes do not indicate what could be the potential best or worst case scenarios.

Equity securities	$	11,785	35% increase	$	15,909	19.3	%
			35% decrease	7,660		(19.3)

Interest Rate Risk

Our fixed maturity investments and senior long-term debt and other debt are subject to interest rate risk. Increases and decreases in interest rates typically result in decreases and increases, respectively, in the fair value of these financial instruments. Our fixed maturity investments are recorded at estimated fair value in our financial statements, and therefore, changes in interest rates impact our financial position and results of operations. Senior long-term debt and other debt is recorded at amortized cost in our financial statements, and therefore, changes in fair value do not impact our financial position or results of operations.

Premiums from our underwriting operations are invested predominantly in high-quality government and municipal bonds and agency mortgage-backed securities that generally match the duration and currency of our loss reserves. As of December 31, 2025, our fixed maturity portfolio had an average duration of 3.9 years and 96% of the portfolio was rated "AA" or better. See note 4(c) of the notes to consolidated financial statements included under Item 8 for details regarding contractual maturity dates of our fixed maturity portfolio. The changes in the estimated fair value of the fixed maturity portfolio are presented as a component of shareholders' equity in accumulated other comprehensive income, net of taxes. We typically hold our fixed maturity investments until maturity, and as a result, unrealized holding gains and losses on these securities are generally expected to reverse as the securities mature.

We work to manage the impact of interest rate fluctuations on our fixed maturity portfolio. The effective duration of the fixed maturity portfolio is managed with consideration given to the estimated duration of our loss reserves. We have investment guidelines that limit the maximum duration and maturity of the fixed maturity portfolio.

We use a commercially available model to estimate the effect of interest rate risk on the fair values of our fixed maturity portfolio and debt. The model estimates the impact of interest rate changes on a wide range of factors including duration, prepayment, put options and call options. Fair values are estimated based on the present value of cash flows, using a representative set of possible future interest rate scenarios. The model requires that numerous assumptions be made about the future. To the extent that any of the assumptions is invalid, incorrect estimates could result. The usefulness of a single point-in-time model is limited, as it is unable to accurately incorporate the full complexity of market interactions.

Foreign Currency Exchange Rate Risk

We have foreign currency exchange rate risk associated with certain of our international operations' assets and liabilities. We manage this risk primarily by matching assets and liabilities that are subject to foreign exchange rate risk as closely as possible. We do this primarily through the purchase of fixed maturity securities that generally match the currency and duration of our loss reserves. We also periodically purchase foreign currency forward contracts and purchase or sell foreign currencies in the open market. Realized and unrealized gains and losses on our forward contracts are recorded in earnings. Our forward contracts generally have maturities of three months.

At December 31, 2025 and 2024, 90% and 91%, respectively, of our invested assets were denominated in United States (U.S.) Dollars. At December 31, 2025 and 2024, 91% and 90%, respectively, of our combined reserves for unpaid losses and loss adjustment expenses and life and annuity benefits were denominated in U.S. Dollars. At those dates, the largest foreign currency denominated balances within both our invested assets and reserves for unpaid losses and loss adjustment expenses and life and annuity benefits were the Euro and British Pound Sterling.

At December 31, 2025 and 2024, our foreign currency denominated assets and liabilities that are subject to foreign currency exchange rate risk were substantially matched or hedged.

10K - 68

Credit Risk

Credit risk, which is not considered a market risk, is the risk that an entity becomes unable or unwilling to fulfill their obligation to us. Our primary credit risks are the credit risk within our fixed maturity portfolio and the credit risk related to our reinsurance recoverables.

Fixed Maturity Investments

Credit risk exists within our fixed maturity portfolio from the potential for loss resulting from adverse changes in an issuer's ability to repay its debt obligations. We monitor our investment portfolio to ensure that credit risk does not exceed prudent levels. We have consistently invested in high credit quality, investment grade securities. As of December 31, 2025, 96% of our fixed maturity portfolio was rated "AA" or better. Our policy is to invest in investment grade securities and to minimize investments in fixed maturity securities that are unrated or rated below investment grade. Our fixed maturity portfolio includes securities issued with financial guaranty insurance. We purchase fixed maturity securities based on our assessment of the credit quality of the underlying assets without regard to insurance.

Our fixed maturity portfolio includes securities issued by foreign governments and non-sovereign foreign institutions. General concern exists about foreign countries that experience financial difficulties during periods of adverse economic conditions. We monitor developments in foreign countries, currencies, and issuers that could pose risks to our fixed maturity portfolio, including ratings downgrades, political and financial changes, and the widening of credit spreads. Our fixed maturity portfolio is highly diversified and comprised of high quality securities.

We obtain information from news services, data providers, rating agencies, and various financial market participants to assess potential negative impacts on a country or company's financial risk profile. We analyze concentrations within our fixed maturity portfolio by country, currency, and issuer, which allows us to assess our level of diversification with respect to these exposures, reduce troubled exposures should they occur, and mitigate any future financial distress that these exposures could cause.

Our fixed maturity portfolio also includes securities issued by municipalities. General concern exists about municipalities that experience financial difficulties during periods of adverse economic conditions. We manage the exposure to credit risk in our municipal bond portfolio by investing in high quality securities and by diversifying our holdings, which are typically either general obligation or revenue bonds related to essential products and services.

Reinsurance Recoverables

We have credit risk related to our reinsurance recoverables to the extent any of our reinsurers are unwilling or unable to meet their obligations to us under our ceded reinsurance agreements. We monitor changes in the financial condition of each of our reinsurers, and we assess our concentration of credit risk on a regular basis. While we believe our net reinsurance recoverable balances are collectible, deterioration in reinsurers' ability to pay, or collection disputes, could adversely affect our operating cash flows, financial position, and results of operations.

Underwriting

Within our underwriting operations, our reinsurance recoverables balance for the ten largest reinsurers, by group, was $3.7 billion at December 31, 2025, representing 63% of the $5.8 billion total reinsurance recoverables, before considering allowances for credit losses. We were the beneficiary of letters of credit, trust accounts, and funds withheld in the aggregate amount of $1.1 billion at December 31, 2025, collateralizing reinsurance recoverable balances due from these ten reinsurers, and $1.5 billion for our total reinsurance recoverables balance. For the ten largest reinsurers, by group:

•Five have a group rating of "A" or better by A.M. Best Company (A.M. Best);

•Four have a group rating of "A-" or "BBB+" by A.M. Best; however, all of the risk-bearing reinsurers within these groups, which are party to our contracts, are rated "A" or better by A.M. Best; and

•The remaining reinsurer, Hagerty Reinsurance Limited, which is a related party, is not rated; however, collateral held exceeded the related reinsurance recoverable as of December 31, 2025.

10K - 69

We attempt to minimize credit exposure to reinsurers through adherence to internal reinsurance guidelines. To participate in our reinsurance program, prospective reinsurers generally must: (i) maintain an A.M. Best or Standard & Poor's rating of "A" (excellent) or better; (ii) maintain minimum capital and surplus of $750 million; and (iii) provide collateral for recoverables in excess of an individually established amount. We also consider qualitative factors when evaluating reinsurers for eligibility to participate in our reinsurance program. In addition, certain foreign reinsurers for our U.S. insurance operations must provide collateral equal to 100% of recoverables, with the exception of reinsurers who have been granted certified, reciprocal jurisdiction, or authorized status by an insurance company's state of domicile. Our credit exposure to Lloyd's of London syndicates is managed through individual and aggregate exposure thresholds.

Fronting

Within State National's program services operations, our reinsurance recoverables balance for the ten largest reinsurers, by group, was $5.5 billion at December 31, 2025, representing 63% of the $8.8 billion total reinsurance recoverables, before considering allowances for credit losses. We were the beneficiary of letters of credit, trust accounts, and funds withheld in the aggregate amount of $3.6 billion at December 31, 2025, collateralizing reinsurance recoverable balances due from these ten reinsurers, and $5.2 billion for our total reinsurance recoverables balance. For the ten largest reinsurers, by group:

•The largest reinsurer, Longtail Re Ltd., is not rated; however, collateral held exceeded the related reinsurance recoverable as of December 31, 2025;

•Six reinsurers have a group rating of "A" or better by A.M. Best;

•One reinsurer is a commercial automobile insurance plan (CAIP), as further described below, for which credit risk is minimal; and

•For the two remaining reinsurers, substantially all of our reinsurance recoverables balances were collateralized as of December 31, 2025.

State National mitigates credit risk by (i) selecting well capitalized, highly rated authorized reinsurers; (ii) requiring that the reinsurer post substantial collateral to secure the reinsured risks, which, in some instances, exceeds the related reinsurance recoverable; or (iii) utilizing voluntary residual market pool arrangements, including CAIPs, that are established pursuant to state law, for which credit risk is considered minimal due to statutory backing, mandatory participation, and the authority to levy assessments on participating insurers. For reinsurers with a credit rating lower than "A" we employ a stringent collateral monitoring program, under which the majority of the reinsurance recoverable balances is fully collateralized. These collateral requirements are regularly monitored by a credit committee at State National.

For Markel Insurance's fronting operations, our total reinsurance recoverables balance was $402.2 million at December 31, 2025. As of December 31, 2025, we held investor collateral that exceeded the related reinsurance recoverables. For this business, we require collateral up to a specified level of annual aggregate agreement year losses, which we believe is unlikely to be exceeded. This collateral is held in a trust for which we are the beneficiary. The required collateral is monitored regularly against the annual aggregate agreement year losses to ensure adequacy of the collateral in the event of a loss.

Item 8. FINANCIAL STATEMENTS AND SUPPLEMENTARY DATA

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Markel Group Inc.:

Opinion on the Consolidated Financial Statements

We have audited the accompanying consolidated balance sheets of Markel Group Inc. and subsidiaries (the Company) as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, changes in equity, and cash flows for each of the years in the three‑year period ended December 31, 2025, and the related notes and financial statement schedules II and III (collectively, the consolidated financial statements). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2025 and 2024, and the results of its operations and its cash flows for each of the years in the three‑year period ended December 31, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission, and our report dated February 26, 2026 expressed an unqualified opinion on the effectiveness of the Company's internal control over financial reporting.

Basis for Opinion

These consolidated financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on these consolidated financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the consolidated financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the consolidated financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the consolidated financial statements. We believe that our audits provide a reasonable basis for our opinion.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

Estimation of the liability for unpaid losses and loss adjustment expenses for the Company's underwriting

operations

As described in Note 11, the Company has recorded a liability for unpaid losses and loss adjustment expenses (loss reserves) of $30.9 billion as of December 31, 2025. Of this amount, $22.1 billion represents loss reserves for the Company's underwriting operations. The Company's actuaries use established actuarial methods and past development patterns to estimate ultimate losses to be paid. For its underwriting operations, loss reserves are established at the Company's best estimates, which incorporate the actuarial point estimates and are adjusted for certain subjective factors.

10K - 71

We identified the assessment of loss reserve estimation for the Company's underwriting operations as a critical audit matter because it involved significant measurement uncertainty, which required complex auditor judgment. The assessment of actuarial methods and key assumptions used to estimate ultimate losses required specialized actuarial skills and subjective auditor judgment. Key assumptions included weighting of actuarial methods, expected loss ratios, and patterns and variability of loss development.

The following are the primary procedures we performed to address this critical audit matter. With the assistance of actuarial professionals, as appropriate, we evaluated the design and tested the operating effectiveness of internal controls over the Company's loss reserving process for its underwriting operations. This included controls over key assumptions and the determination of loss reserves. Additionally, we also involved actuarial professionals with specialized skills and knowledge, who assisted in:

•assessing the Company's actuarial methodologies by comparing to generally accepted actuarial methodologies and evaluating the weighting of the methods based on common industry practice

•developing independent actuarial estimates for certain product lines using the Company's underlying historical claims and policy data

•developing an independent range of consolidated loss reserves based on actuarial methods and assumptions, comparing those results to the Company's recorded reserves and evaluating the movement of the Company's recorded reserve within our range

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. See note 2 for details regarding reportable segments.

a) Basis of Presentation. 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 any 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 non-insurance operating businesses 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.

In 2025, the Company changed the presentation of its consolidated statements of income and comprehensive income to present net investment gains outside of operating revenues. Prior periods have been conformed to this presentation.

b) Use of Estimates. 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. Management periodically reviews its estimates and assumptions. Quarterly reviews include evaluating the adequacy of reserves for unpaid losses and loss adjustment expenses and contingencies. Estimates and assumptions for goodwill and intangible assets are reviewed in conjunction with an acquisition, and goodwill and indefinite-lived intangible assets are reassessed at least annually for impairment. Actual results may differ materially from the estimates and assumptions used in preparing the consolidated financial statements.

c) Investments. Available-for-sale investments and equity securities are recorded at estimated fair value. Available-for-sale investments include fixed maturity securities and short-term investments. Fixed maturity securities include government and municipal bonds and mortgage-backed securities with original maturities of more than one year. Short-term investments are primarily comprised of treasury bills with original maturities of one year or less.

Realized investment gains or losses on available-for-sale investments are included in net income. Realized gains or losses from sales of available-for-sale investments are derived using the first-in, first-out method on the trade date. Unrealized gains and losses on available-for-sale investments, net of income taxes, are included in other comprehensive income. The Company completes a detailed analysis each quarter to assess declines in the fair value of its available-for-sale investments. Any credit-related impairment losses on the Company's available-for-sale investments are recorded as an allowance, subject to reversal, and recognized in net income. Realized and unrealized gains and losses on equity securities are included in net income as net investment gains or losses.

Premiums and discounts are amortized or accreted over the lives of the related fixed maturity securities as an adjustment to the yield using the effective interest method. Dividend and interest income are recognized when earned. Accrued interest receivable is excluded from both the estimated fair value and the amortized cost basis of available-for-sale securities and included within other assets on the Company's consolidated balance sheets. Any uncollectible accrued interest receivable is written off in the period it is deemed uncollectible.

See note 4 and note 5 for further details regarding the Company's investment portfolio.

d) Cash and Cash Equivalents. The Company considers all investments with original maturities of 90 days or less to be cash equivalents, with the exception of treasury bills, which are classified as short-term investments. The carrying value of the Company's cash and cash equivalents approximates fair value.

e) Restricted Cash and Cash Equivalents. Cash and cash equivalents that are restricted as to withdrawal or use are recorded as restricted cash and cash equivalents. The carrying value of the Company's restricted cash and cash equivalents approximates fair value.

10K - 77

f) Receivables. Receivables include premiums receivable, which represent premiums that are both currently due and amounts not yet due on insurance and reinsurance policies. Premiums for insurance policies are generally due at inception. Premiums for reinsurance policies generally become due over the period of coverage based on the policy terms. Changes in the estimate of reinsurance premiums written will result in an adjustment to premiums receivable in the period they are determined. Receivables also include amounts receivable from contracts with customers, which represent the Company's unconditional right to consideration for satisfying the performance obligations outlined in the contract.

The Company monitors credit risk associated with receivables, taking into consideration the fact that in certain instances credit risk may be reduced by the Company's right to offset loss obligations or unearned premiums against premiums receivable. An allowance is established for credit losses expected to be incurred over the life of the receivable, which is recorded net of this allowance. The allowance is charged to net income in the period the receivable is recorded and revised in subsequent periods to reflect changes in the Company's estimate of expected credit losses. See note 7 for further details regarding receivables.

g) Reinsurance Recoverables. Amounts recoverable from reinsurers are estimated in a manner consistent with the claim liability associated with the reinsured business. Reinsurance recoverable estimates also consider the frequency and severity of the underlying claims, which ultimately determines coverage under the applicable ceded reinsurance contracts. The Company evaluates the financial condition of its reinsurers and monitors concentration of credit risk to minimize its exposure to significant losses from individual reinsurers. To further reduce credit exposure on reinsurance recoverables, the Company has received collateral, including letters of credit and trust accounts, from certain reinsurers. Cash collateral related to these reinsurance agreements is available, without restriction, when the Company pays losses covered by the reinsurance agreements. An allowance is established for credit losses expected to be incurred over the life of the reinsurance recoverable, which is recorded net of this allowance. The allowance is charged to net income in the period the recoverable is recorded and revised in subsequent periods to reflect changes in the Company's estimate of expected credit losses. As of December 31, 2025 and 2024, the allowance for credit losses associated with the Company's reinsurance recoverables was not material to the consolidated financial statements. See note 12 for further details regarding reinsurance recoverables.

h) Deferred Policy Acquisition Costs. Costs directly related to the acquisition of insurance premiums are deferred and amortized over the related policy period, generally one year. The Company only defers acquisition costs incurred that are directly related to the successful acquisition of new or renewal insurance contracts, including commissions to agents and brokers, salaries and benefits, and premium taxes. Commissions received related to reinsurance premiums ceded are netted against broker commissions in determining acquisition costs eligible for deferral. To the extent that future policy revenues on existing policies are not adequate to cover related costs and expenses, deferred policy acquisition costs are charged to earnings. The Company does not consider anticipated investment income in determining whether a premium deficiency exists. See note 2(a) and Schedule III for further details regarding policy acquisition costs.

i) Goodwill and Intangible Assets. Goodwill and intangible assets are recorded as a result of business acquisitions. Goodwill represents the excess of the amount paid to acquire a business over the net fair value of assets acquired and liabilities assumed at the date of acquisition. Indefinite-lived and other intangible assets are recorded at fair value as of the acquisition date. The determination of the fair value of certain assets acquired and liabilities assumed involves significant judgment and the use of valuation models and other estimates, which require assumptions that are inherently subjective. Goodwill and indefinite-lived intangible assets are tested for impairment at least annually. The Company completes an annual test during the fourth quarter of each year based upon the results of operations through September 30. Intangible assets with definite lives are amortized using the straight-line method over their estimated useful lives, generally five to 20 years, and are reviewed for impairment when events or circumstances indicate that their carrying value may not be recoverable. See note 8 for further details regarding goodwill and intangible assets.

j) Equity Method Investments. The Company holds certain investments that are required to be accounted for under the equity method, whereby the investments initially are recorded at cost within other assets on the consolidated balance sheets and subsequently increased or decreased by the Company's proportionate share of the net income or loss of the investee and other transactions impacting the investee's equity. The Company records its proportionate share of net income or loss of the investee in services and other revenues. Dividends or other equity distributions are recorded as a reduction of the investment. The Company reviews equity method investments for impairment when events or circumstances indicate that a decline in the fair value of the investment below its carrying value is other-than-temporary. See note 6 for further details regarding the Company's equity method investments.

k) Property and Equipment. Property and equipment is stated at cost less accumulated depreciation. Depreciation of property and equipment is calculated using the straight-line method over the estimated useful lives of the respective assets.

10K - 78

Property and equipment, net of accumulated depreciation, was $1.5 billion and $1.4 billion as of December 31, 2025 and 2024, respectively, and is included in other assets on the Company's consolidated balance sheets.

l) Leases. The present value of future lease payments for the Company's leases with terms greater than 12 months is included on the consolidated balance sheets as lease liabilities and right-of-use lease assets within other liabilities and other assets, respectively. The Company's lease portfolio primarily consists of operating leases, as well as finance leases.

The Company's operating leases relate to real estate and equipment. Total expected lease payments for operating leases are based on the lease payments specified in the contract and the stated term, including any options to extend or terminate that the Company is reasonably certain to exercise. The Company accounts for lease components and any associated non-lease components within a contract as a single lease component, and therefore allocates all of the expected lease payments to the lease component.

The lease liability, which represents the Company's contractual obligation to make lease payments, is calculated based on the present value of expected lease payments over the remaining lease term, discounted using the Company's collateralized incremental borrowing rate at the lease commencement date. The lease liability is then adjusted for any prepaid rent, lease incentives received, or capitalized initial direct costs to determine the lease asset, which represents the Company's right to use the underlying asset for the lease term.

Total lease costs are primarily comprised of rental expense for operating leases, which is recognized on a straight line basis over the lease term. Rental expense attributable to the Company's underwriting operations is included in underwriting, acquisition, and insurance expenses and rental expense attributable to the Company's other operations is included in products expenses and services and other expenses in the consolidated statements of income and comprehensive income. See note 9 for further details regarding operating leases.

m) Inventories. Inventories are maintained at certain of the Company's operating businesses and consist primarily of raw materials, work-in-process, and finished goods. Inventories are generally valued based on the nature of the inventory, including the first-in-first-out, standard cost, and specific identification methods, and stated at the lower of cost or net realizable value. Inventories were $703.4 million and $731.1 million as of December 31, 2025 and 2024, respectively, and are included in other assets on the Company's consolidated balance sheets.

n) Redeemable Noncontrolling Interests. The Company owns controlling interests in companies across a variety of industries. In some cases, the Company has the option to acquire the remaining equity interests, and the remaining equity interests have the option to sell their interests to the Company, in the future. The redemption value of the remaining equity interests is generally based on the respective company's earnings in specified periods preceding the redemption date. The redeemable noncontrolling interests are redeemable in 2026 or become redeemable between 2027 and 2033.

The Company recognizes changes in the redemption value that exceed the carrying value of redeemable noncontrolling interests to retained earnings as if the balance sheet date was also the redemption date. Changes in the redemption value also result in an adjustment to net income to common shareholders in the calculation of basic and diluted net income per common share. See note 19 for further details regarding the calculation of basic and diluted net income per common share.

o) Income Taxes. The Company records deferred income taxes to reflect the net tax effect of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and their tax bases. Deferred tax assets and liabilities are measured using enacted tax rates expected to apply to taxable income in years in which those temporary differences are expected to be recovered or settled. Deferred tax assets are reduced by a valuation allowance when management believes it is more likely than not that some, or all, of the deferred tax assets will not be realized. The Company recognizes the tax benefit from an uncertain tax position taken or expected to be taken in income tax returns only if it is more likely than not that the tax position will be sustained upon examination by tax authorities, based on the technical merits of the position. Tax positions that meet the more likely than not threshold are then measured using a probability weighted approach, whereby the largest amount of tax benefit that is greater than 50% likely of being realized upon ultimate settlement is recognized. The Company recognizes interest and penalties related to uncertain tax positions in income tax expense. See note 15 for further details regarding income taxes.

p) Unpaid Losses and Loss Adjustment Expenses. Unpaid losses and loss adjustment expenses on the Company's property and casualty insurance business are based on evaluations of reported claims and estimates for losses and loss adjustment expenses incurred but not reported (IBNR). Estimates for losses and loss adjustment expenses incurred but not reported are

10K - 79

based on reserve development studies, among other things. Recorded reserves are estimates, and the ultimate liability may be greater or less than the estimates. See note 11 for further details regarding unpaid losses and loss adjustment expenses.

q) Life and Annuity Benefits. The Company has a run-off block of life and annuity reinsurance contracts that subject the Company to mortality, longevity, and morbidity risks. The contracts consist primarily of Euro and U.S. Dollar denominated life-contingent payout annuities and traditional and universal life contracts. The primary component of the Company's liabilities for life and annuity benefits is the present value of 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 benefit 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 liability for future policyholder benefits are reviewed, and updated as necessary, at least annually. The discount rate assumptions are updated at each reporting date. Interest accretion for the reserves is calculated using the discount rate locked-in at contract inception, which was 2.3%.

The liability for future policyholder benefits is remeasured each period using current discount rates, based on yields for upper-medium grade fixed maturity securities, with the impact of changes in the discount rate included in other comprehensive income, net of taxes. All other results attributable to the run-off of life and annuity reinsurance contracts are included in services and other revenues and services and other expenses. Investment income earned on the investments that support the liability for future policyholder benefits is included in net investment income. Because of the uncertainty in the assumptions used to estimate reserves for life and annuity benefit obligations and the long-term nature of these reinsurance contracts, the ultimate liability may be greater or less than the estimated liability. The Company's liabilities for life and annuity benefits are included in other liabilities on the Company's consolidated balance sheets. See note 13 for further details regarding life and annuity benefits.

r) Revenue Recognition.

Property and Casualty Premiums

Insurance premiums written are generally recorded at the inception of a policy and earned on a pro rata basis over the policy period, typically one year. The cost of reinsurance ceded is initially recorded as prepaid reinsurance premiums and is amortized over the reinsurance contract period in proportion to the amount of insurance protection provided. Premiums ceded are netted against premiums written. For multi-year contracts where insurance premiums are payable in annual installments, written premiums are recorded at the inception of the contract based on management's best estimate of total premiums to be received. For contracts where the cedent has the ability to unilaterally commute or cancel coverage within the term of the policy, written premiums are generally recorded on an annual basis or up to the contract cancellation point. The remaining premiums are estimated and included as written at each successive anniversary date within the multi-year term.

Assumed reinsurance premiums are recorded at the inception of each contract based upon contract terms and information received from cedents and brokers and are earned on a pro rata basis over the coverage period, or for multi-year contracts, in proportion with the underlying risk exposure to the extent there is variability in the exposure through the coverage period. Changes in reinsurance premium estimates are expected and may result in significant adjustments in any period. These estimates change over time as additional information regarding changes in underlying exposures is obtained. Any subsequent differences arising on such estimates are recorded as premiums written in the period they are determined and are earned on a pro rata basis over the coverage period, or immediately if the coverage period has ended. The Company uses the periodic method to account for assumed reinsurance from foreign reinsurers as a result of the sufficiency of the information provided by the reinsurer, which is consistent with its accounting for assumed reinsurance from U.S. reinsurers.

Certain contracts that the Company writes provide for reinstatement of coverage. Reinstatement premiums are the premiums for the restoration of the insurance or reinsurance limit of a contract to its full amount after a loss occurrence by the insured or reinsured. The Company accrues for reinstatement premiums resulting from losses recorded. Such accruals are based upon contractual terms and management judgment is involved with respect to the amount of losses recorded. Changes in estimates of losses recorded on contracts with reinstatement premium features will result in changes in reinstatement premiums based on contractual terms. Reinstatement premiums are recognized as premiums written at the time losses are recorded and are generally earned on a pro rata basis over the remaining coverage period.

10K - 80

Other Revenues

Other revenues primarily consist of revenues from the sale of products and services. Revenues are recognized when, or as, control of the promised goods or services is transferred to the Company's customers, in an amount that reflects the consideration the Company expects to be entitled to in exchange for those goods or services. Contracts with customers generally have an original term of one year or less. For contracts with customers that have an original term greater than one year, the Company recognizes revenue at the amount for which it has a right to invoice for the products delivered or services performed. Certain customers may receive volume rebates or credits for products and services, which are accounted for as variable consideration. The Company estimates these amounts based on the expected amount to be provided to the customer and reduces revenues recognized by a corresponding amount. The Company does not expect significant changes to its estimates of variable consideration over the term of the contracts.

Payment terms for products and services vary by the type of product or service offered and the location of the customer, and payment is typically received at or shortly after the point of sale. For certain products, the Company requires partial payment in the form of a deposit before the products are delivered to the customer, which is included in other liabilities on the Company's consolidated balance sheets.

The Company's other revenues consist primarily of the following:

Products. The Company has several different businesses that manufacture or produce a variety of products, including ornamental plants, precast concrete, industrial bakery equipment, car hauler equipment, dredges, residential homes, and flooring for dry van trailers. Revenues for these products are generally recognized when the products are shipped to the customer or the products arrive at the agreed upon destination with the end customer. For certain products, revenues are recognized based on percentage of completion. Additionally, some of the Company's contracts include multiple performance obligations. For such arrangements, revenues are allocated to each performance obligation based on the relative standalone selling price, which is derived from amounts stated in the contract.

Services. The Company has several different businesses that provide various types of services, including distribution of exterior building products, fire protection and life safety solutions, and consulting services. Service revenues are generally recognized either at a point-in-time when services are provided or over the term of the contracts based on hours incurred or as services are provided. Revenue recognition for other services provided by the Company's businesses is as follows:

Leasing. Certain of the Company's businesses earn revenues through the leasing of equipment. The revenues from these leases are generally recognized on a straight-line basis over the term of the lease.

Fronting. Certain of the Company's businesses offer fronting services through which it earns revenues in the form of fronting fees, or ceding fees. Fronting generally refers to insurance premiums written on behalf of a general agent or capacity provider that are then fully ceded to a capacity provider in exchange for ceding fees. Ceding fees are based on the gross premiums written and are earned in a manner consistent with the recognition of the gross premiums earned on the underlying insurance policies, generally on a pro rata basis over the terms of the underlying policies reinsured.

Investment Management. Through the Company's insurance-linked securities operations, the Company earns revenues in the form of investment management fees. Investment management fees are recognized over the period in which investment management services are provided and are calculated and recognized monthly, based on either the net asset value of the accounts managed or gross premium volume for the underlying risks. For certain accounts, the Company is also entitled to participate, on a fixed-percentage basis, in any net income generated in excess of an agreed-upon threshold as established by the underlying investment management agreements. In general, net income is calculated at the end of each calendar year and performance fees are payable annually. Performance fees are recognized at the conclusion of the contractual performance period, when the uncertainty related to performance has been resolved.

See note 10 for further details regarding products, services, and other revenues.

s) Program Services. In connection with its program services fronting operations, the Company enters into contractual agreements with both producing general agents and reinsurers, whereby the general agents and reinsurers are typically obligated to each other for payment of insurance amounts, including premiums, commissions, and losses. To the extent these funds are not the obligation of the Company and are settled directly between the general agent and the reinsurer, no

receivables or payables are recorded for these amounts. All obligations of the Company's insurance subsidiaries owed to or on behalf of their policyholders are recorded by the Company and, to the extent appropriate, offsetting reinsurance recoverables are recorded.

t) Foreign Currency Transactions. The U.S. Dollar is the Company's reporting currency and the primary functional currency of its foreign underwriting operations. The functional currencies of the Company's other foreign operations are the currencies of the primary economic environments in which the majority of their business is transacted.

Foreign currency transaction gains and losses are the result of exchange rate changes on transactions denominated in currencies other than the functional currency at each foreign entity. Monetary assets and liabilities are remeasured to the functional currency at current exchange rates, with resulting gains and losses included in net foreign exchange gains within net income. Non-monetary assets and liabilities are remeasured to the functional currency at historic exchange rates. Available-for-sale securities are recorded at fair value with resulting gains and losses, including the portion attributable to movements in exchange rates, included in the change in net unrealized gains on available-for-sale investments, net of taxes within other comprehensive income. While the Company attempts to naturally hedge its exposure to foreign currency fluctuations by matching assets and liabilities in the same currencies, there is a financial statement mismatch between the gains or losses recorded in net income related to insurance reserves denominated in non-functional currencies and the gains or losses recorded in other comprehensive income related to the available-for-sale securities held in non-functional currencies supporting the reserves.

Assets and liabilities of foreign operations denominated in a functional currency other than the U.S. Dollar are translated into the U.S. Dollar at current exchange rates, with resulting gains or losses included in other comprehensive income, net of taxes.

u) Comprehensive Income. Comprehensive income represents all changes in equity that result from recognized transactions and other economic events during the period. Other comprehensive income refers to revenues, expenses, gains, and losses that under U.S. GAAP are included in comprehensive income but excluded from net income, such as unrealized gains or losses on available-for-sale investments, the impact of changes in the discount rate for life and annuity benefits, foreign currency translation adjustments, and changes in net actuarial pension loss. See note 20 for further details regarding other comprehensive income.

v) Net Income Per Common Share. Basic net income per common share is computed by dividing adjusted net income to shareholders by the weighted average number of common shares outstanding during the year. Diluted net income per common share is computed by dividing adjusted net income to shareholders by the sum of the weighted average number of common shares and dilutive potential common shares outstanding during the year. See note 19 for further details regarding the calculation of basic and diluted net income per common share.

w) Variable Interest Entities. The Company determines whether it has relationships with entities defined as VIEs in accordance with Financial Accounting Standards Board (FASB) Accounting Standards Codification (ASC) 810, Consolidation. Under this guidance, a VIE is consolidated by the variable interest holder that is determined to be the primary beneficiary. The Company determines whether an entity is a VIE at the inception of its variable interest in the entity and upon the occurrence of certain reconsideration events. The Company continually reassesses whether it is the primary beneficiary of VIEs in which it holds a variable interest. See note 17 for further details regarding the Company's involvement with VIEs.

x) Recent Accounting Pronouncements.

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 became effective for this Annual Report on Form 10-K and was applied using a prospective approach. The standard only impacts required disclosures and did not impact the Company's financial position, results of operations, or cash flows. See note 15 for the Company's income tax disclosures.

In November 2024, the FASB issued ASU No. 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures. The standard requires disclosure of certain prescribed costs and expenses within the notes to consolidated financial statements. ASU No. 2024-03 becomes effective for the Company's 2027 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. The Company is currently in the early stages of evaluating the impact of ASU No. 2024-03 on its disclosures.

2. Segment Reporting Disclosures

The Company has four reportable segments: Markel Insurance, Industrial, Financial, and Consumer and Other. The Company's chief operating decision maker is the chief executive officer.

In 2025, management made changes to the structure and leadership of its insurance operations, resulting in changes to its operating and reportable segments, primarily the creation of the Markel Insurance segment. Markel Insurance's underwriting operations were previously reported through the Company's Insurance and Reinsurance segments.

Management also made changes to the Company's operating and reportable segments in 2025 to reflect changes in how the chief operating decision maker assesses the Company's other set of businesses and investments. The businesses previously reported under the Markel Ventures segment, as well as the Company's State National and Nephila businesses, which previously were not included in a reportable segment, are now reported in three new reportable segments: Industrial, Financial, and Consumer and Other. Additionally, the results from the Company's investing activities, previously reported in the Investing segment, are now attributed to the Company's segments or corporate operations based on the subsidiary that holds the investments. Markel Insurance's subsidiaries hold the most significant portion of the Company's investments. Prior periods have been recast to conform to the current presentation.

The Markel Insurance segment is the Company's core specialty insurance business, which is comprised of underwriting and other insurance-related activities. The Markel Insurance segment aligns with the business's network of insurance subsidiaries under the common leadership of the Markel Insurance chief executive officer. In August 2025, Markel Insurance sold the renewal rights for business written in its Global Reinsurance division, and the division entered into run-off. The Global Reinsurance division's gross premium volume in 2025 was $1.0 billion. As many of the contracts previously written within this division are multi-year agreements, the Company expects premiums to continue earning over the next two to three years and loss reserves are expected to take several additional years to run off.

The Industrial segment consists of businesses that operate in the industrial sector. These businesses distribute building products, provide fire protection and life safety solutions, and manufacture a variety of products, including precast concrete, car hauler equipment, industrial baking equipment, flooring for dry van trailers, dredges, and wall systems. Other businesses in the Industrial segment provide equipment rental services and erosion control and stormwater management services.

The Financial segment consists of businesses that operate in the insurance services and investment management industries, including the Company's State National and Nephila businesses, as well as certain insurance-linked securities investment management businesses that are in run-off.

The Consumer and Other segment consists of businesses that operate in the consumer sector, as well as a variety of other sectors. These businesses produce ornamental houseplants, build homes, design leather handbags, and own and operate manufactured housing communities. Other businesses in the Consumer and Other segment provide information technology consulting services, retail intelligence, concierge primary healthcare, and sponsorship of international teachers.

The Company's corporate operations, which are not an operating or reportable segment, are comprised of holding company activities, which include capital allocation, leadership support, and performing the responsibilities consistent with sound governance and required of a public company. The Company's corporate operations include activities at Markel Group Inc. and investments and loans to and from its operating businesses, which are held by other corporate subsidiaries. Historically, corporate expenses were fully allocated to the Company's segment results, however, beginning in the third quarter of 2025, the Company discontinued allocating corporate expenses that are not integral to operating its underlying businesses.

Intersegment transactions primarily consist of loans from Markel Insurance to a corporate subsidiary to fund certain non-insurance acquisitions and from a corporate subsidiary to certain non-insurance businesses to fund strategic growth investments and projects. The Company's chief operating decision maker considers these loans, and the related interest income, to be similar to invested assets held by the respective segment. Interest income on these intercompany loans is included in the respective segment's profit and is eliminated in consolidation.

Segment profit for all of the Company's segments is measured by adjusted operating income, which does not include net investment gains, amortization of acquired intangible assets, or impairment of goodwill. Net investment gains and losses, which are primarily comprised of unrealized gains and losses on equity securities, are evaluated separately by the chief operating decision maker when assessing periodic segment financial performance due to the inherent volatility of these gains and losses, which can temporarily obscure the underlying segment performance. The chief operating decision maker believes such amounts are more meaningful when evaluated over longer periods of time. Amortization of acquired intangible assets and impairment of goodwill, which arise from purchase accounting for acquisitions, are not considered a cost of operating the underlying businesses.

a) The following tables summarize the Company's segment disclosures. The Company's chief operating decision maker reviews net investment gains and losses by segment separately from segment profit.

Markel Insurance does not manage products at this level of aggregation as it offers a diverse portfolio of products and manages these products in more disaggregated groupings.

During the years ended December 31, 2025, 2024, and 2023, 73%, 75%, and 76%, respectively, of underwriting gross premiums written in the Company's Markel Insurance segment were attributed to risks or cedents located in the United States.

Most of the Markel Insurance segment's underwriting gross written premiums are placed through insurance and reinsurance brokers. During the years ended December 31, 2025, 2024, and 2023, the Markel Insurance segment's top five independent brokers accounted for 37%, 39%, and 38% of its underwriting gross premiums written.

3. Acquisitions

Educational Partners International

In September 2024, the Company acquired a 68% ownership interest in Educational Partners International (EPI), a company that sponsors international teachers for placements in schools in the U.S. Total consideration for the Company's investment was $167.7 million, all of which was cash. The Company has the option to acquire the remaining equity interests and the remaining equity holders have the option to sell their interests to the Company in the future. Through January 15, 2025, the Company's investment was accounted for under the equity method, as the Company did not have control over the business due to regulatory approval that was still pending. On January 16, 2025, the Company received regulatory approval, which resulted in the control and consolidation of EPI.

Upon consolidation, the purchase price was preliminarily allocated to the acquired assets and liabilities of EPI based on estimated fair value at the consolidation date. Upon completing the process of determining the fair value of the assets acquired and liabilities assumed with EPI, the Company recognized goodwill of $65.3 million, intangible assets of $182.0 million, and redeemable noncontrolling interest of $81.2 million. Goodwill is primarily attributable to expected future earnings and cash flow potential of EPI, and it is expected to be deductible for income tax purposes. Intangible assets include $160.0 million attributed to an indefinite-lived intangible asset for a designation from the U.S. Department of State that authorizes EPI to sponsor international teachers for placements in schools in the U.S. The remaining intangible assets include $10.0 million of trade names, $2.0 million of technology, and $10.0 million of other intangible assets, which are being amortized over 12 years, 5 years, and 15 years, respectively. Results attributable to EPI are included in the Company's Consumer and Other segment.

Valor Environmental

In June 2024, the Company acquired 98% of Valor Environmental (Valor), an environmental services company providing erosion control and related services to commercial development sites and homebuilders throughout the U.S. Total consideration for the transaction was $156.4 million, all of which was cash. The Company has the option to acquire the remaining equity interests and the remaining equity holders have the option to sell their interests to the Company in the future.

Upon acquisition, the purchase price was preliminarily allocated to the acquired assets and liabilities of Valor based on estimated fair value at the acquisition date. In 2025, the Company completed the process of determining the fair value of the assets acquired and liabilities assumed with Valor and recognized goodwill of $73.4 million and intangible assets of $92.5 million. The final purchase price allocation reflected differences from the preliminary purchase price allocation upon completion of a third-party valuation, including a $43.5 million increase in the amount recognized for intangible assets and an increase in the corresponding deferred tax liability. The final purchase price allocation adjustments resulted in a $34.9 million net decrease to goodwill from the preliminary amount recognized. Goodwill is primarily attributable to expected future earnings and cash flow potential of Valor, and a portion of it is not deductible for income tax purposes. Intangible assets include $82.0 million of customer relationships, $6.0 million of trade names, and $4.5 million of other intangible assets, which are being amortized over 17 years, 15 years, and 5 years, respectively. Results attributable to Valor are included in the Company's Industrial segment.

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 December 31, 2025 or 2024.

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.

c) The amortized cost and estimated fair value of fixed maturity securities at December 31, 2025 are shown below by contractual maturity. The average duration of fixed maturity securities at December 31, 2025 was 3.9 years. Actual maturities may differ from contractual maturities because borrowers may have the right to call or prepay obligations with or without penalties, and the holders may have the right to put the securities back to the issuer.

5. 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.

10K - 91

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.

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, agency, and supranational bonds, mortgage-backed securities, and corporate and university debt securities.

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 and university bonds, and obligations of foreign governments, agencies and supranationals include reported trades, benchmark yields, issuer spreads, bids, offers, credit information, and estimated cash flows. Significant inputs used to determine the fair value of 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.

6. Equity Method Investments

The Company's equity method investments, which are included in other assets on the consolidated balance sheets, totaled $737.6 million and $862.5 million as of December 31, 2025 and 2024, respectively. As of December 31, 2024, the Company's equity method investments included its 2024 investment in EPI, which was consolidated in 2025. See note 3.

The Company's proportionate share of earnings in its equity method investments was income of $70.4 million and $58.7 million for the years ended December 31, 2025 and 2024, respectively, and losses of $2.1 million for the year ended December 31, 2023.

Hagerty, Inc.

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 December 31, 2025 and 2024.

In 2025, the Company, through its program services operations, entered into a retroactive reinsurance contract on behalf of Longtail Re Ltd. (Longtail Re), a third-party capacity provider, under which it assumed loss reserves for a portfolio of insurance policies that were concurrently ceded to Longtail Re. As a result of this transaction, the Company recorded $1.3 billion of gross losses and loss adjustment expenses and $1.3 billion of corresponding reinsurance recoverables. The transaction had no impact on the Company's net reserves for losses and loss adjustment expenses.

In 2025, the Company commuted a portfolio of ceded reinsurance contracts with certain Nephila Reinsurers (see note 18) consisting of property catastrophe and brokerage property exposures for policy years 2023 and prior. Gross and ceded reserves for losses and loss adjustment expenses on the commuted contracts totaled $312.2 million, for which the Company received cash payments of $292.7 million.

In 2025, current accident year losses and loss adjustment expenses included $61.9 million of net losses and loss adjustment expenses attributed to the series of wildfires that occurred in southern California in January 2025. These losses and loss adjustment expenses were net of ceded losses of $67.6 million.

In 2024, current accident year losses and loss adjustment expenses included $70.6 million of net losses and loss adjustment expenses attributed to Hurricane Helene and Hurricane Milton. These losses and loss adjustment expenses were net of ceded losses of $60.4 million.

In 2023, current accident year losses and loss adjustment expenses included $40.1 million of net losses and loss adjustment expenses attributed to the Hawaiian wildfires and Hurricane Idalia. These losses and loss adjustment expenses were net of ceded losses of $9.3 million.

In 2023, the Company completed a retroactive reinsurance transaction to cede its portfolio of policies comprised of liabilities for its run-off book of United Kingdom (U.K.) motor casualty business in exchange for payments totaling $125.1 million, which approximated the carrying value of the Company's reserves for losses and loss adjustment expenses on the ceded policies.

b) Reserving Methodology

Unpaid losses and loss adjustment expenses totaled $30.9 billion as of December 31, 2025, which included $22.1 billion attributable to underwriting activities and $8.8 billion attributable to fronting activities. Reinsurance recoverables attributable to underwriting activities and fronting activities were $5.4 billion and $8.8 billion, respectively, as of December 31, 2025.

The Company uses a variety of techniques to establish liabilities for unpaid losses and loss adjustment expenses based upon estimates of the ultimate amounts payable. The Company maintains reserves for specific claims incurred and reported (case reserves) and reserves for claims incurred but not reported (IBNR reserves), which include expected development on reported claims. The Company does not discount its reserves for losses and loss adjustment expenses to reflect estimated present value.

There is a time lag between when a loss event occurs and when it is reported to the Company, and some claims may not be reported for many years. As a result, the liability for unpaid losses and loss adjustment expenses includes significant estimates for IBNR claims.

The actuarial methods that the Company uses to estimate ultimate losses have been designed to address the lag in loss reporting as well as the delay in obtaining information that would allow the Company to more accurately estimate future payments. The reporting lag can be more pronounced in reinsurance contracts than in the insurance contracts due to a time lag between cedents establishing case reserves or re-estimating their reserves and notifying the Company of those new or revised case reserves. There may also be a more pronounced reporting lag on insurance contracts for which the Company is not the primary insurer and participates only in excess layers of loss. Based on the experience of the Company's actuaries and management, the Company selects loss development factors and trending techniques to mitigate the difficulties caused by reporting lags. At least annually, the Company evaluates its loss development factors and trending assumptions using its own loss data, as well as cedent-specific and industry data, and updates them as needed.

IBNR reserves are based on the estimated ultimate cost of settling claims using past experience adjusted for current trends and any other factors that would modify past experience. IBNR reserves are calculated by subtracting paid losses and loss adjustment expenses and case reserves from estimated ultimate losses and loss adjustment expenses. IBNR reserves were 69% of total unpaid losses and loss adjustment expenses at December 31, 2025 compared to 71% at December 31, 2024.

In establishing liabilities for unpaid losses and loss adjustment expenses, the Company's actuaries estimate an ultimate loss ratio, by accident year or underwriting year, for each product line with input from underwriting and claims personnel. For product lines in the Company's international insurance and run-off reinsurance operations, where loss reserves are established on an underwriting year basis, the Company has developed a methodology to convert from underwriting year to accident year for financial reporting purposes.

In estimating an ultimate loss ratio for a particular line of business, the actuaries may use one or more actuarial reserving methods and select from these a single point estimate. To varying degrees, these methods include detailed statistical analysis of past claim reporting, settlement activity, claim frequency and severity, policyholder loss experience, industry loss experience, and changes in market and economic conditions, policy forms and exposures.

Greater judgment may be required when new product lines are introduced or when there have been changes in claims handling practices, as the statistical data available may be insufficient. Greater judgment also may be required for product lines that experience a low frequency of high severity claims, particularly when the Company is reliant on third-party case reserve estimates and claims handling practices. These estimates also reflect implicit and explicit assumptions regarding the potential effects of external factors, including economic and social inflation, judicial decisions, changes in law, general economic conditions, and recent trends in these factors. Management believes the process of evaluating past experience, adjusted for the effects of current developments and anticipated trends, is an appropriate basis for predicting future events.

Estimates for losses from widespread catastrophic events, such as hurricanes and earthquakes, as well as pandemics and wars, are based on claims received to date, analysis of exposures in the impacted areas, industry loss estimates and output from both industry, broker and proprietary models, as well as analysis of the Company's ceded reinsurance contracts. The level of reliance on these procedures varies depending on the timing of the event relative to the point at which the Company develops its estimates. The Company also considers loss experience on historical events that may have similar characteristics to the underlying event and current market conditions. In the period shortly after an event occurs, more weight is put on modeling and industry estimates, whereas with the passage of time, greater reliance is placed on incurred claims data, individual contract exposures and historical claim patterns. Due to the inherent uncertainty in estimating such losses, these estimates are subject to variability, which increases with the severity and complexity of the underlying event. As additional claims are reported and paid, and industry loss estimates are revised, the Company incorporates this new information into its analysis and adjusts its estimate of ultimate losses and loss adjustment expenses as appropriate.

Loss reserves are established at management's best estimate, which is developed using the actuarially calculated point estimate as the starting point. The actuarial point estimate represents the actuaries' best estimate of the most likely amount that will ultimately be paid to settle the losses that have occurred at a particular point in time. Similarly, the point estimate for ceded losses is calculated based on the ultimate gross loss amount expected to be paid, as well as the frequency and severity of the underlying claims, which ultimately determines coverage under the applicable ceded reinsurance contracts. Therefore, ceded loss estimates are subject to many of the same judgments and assumptions as the gross loss estimates.

Inherent in the Company's reserving practices is the desire to establish loss reserves that are more likely redundant than deficient, and therefore, will ultimately prove to be adequate. This approach to establishing loss reserves results in loss reserves that exceed the calculated actuarial point estimate. Management continually attempts to improve its loss estimation process by refining its ability to analyze loss development patterns, claim payments and other information, but uncertainty remains regarding the potential for adverse development of estimated ultimate liabilities.

The Company's ultimate liability may be greater or less than current reserves. Changes in the Company's estimated ultimate liability for loss reserves generally occur as a result of the emergence of unanticipated loss activity, the completion of specific actuarial or claims studies or changes in internal or external factors that impact the assumptions used to derive the Company's estimates. The Company closely monitors new information on reported claims and uses statistical analyses prepared by its actuaries to evaluate the adequacy of recorded reserves. Management exercises judgment when assessing the relative credibility of loss development trends.

Management currently believes the Company's gross and net reserves are adequate. However, there is no precise method for evaluating the impact of any significant factor on the adequacy of reserves, and actual results will differ from original estimates.

c) Prior Accident Year Loss Development

The following tables summarize the product lines with the most significant changes in prior accident years loss reserves for the years ended December 31, 2025, 2024, and 2023, along with the corresponding accident years and the trends and factors that impacted management's best estimate of ultimate losses and loss adjustment expenses on underlying products in each of these product lines. In 2025, the Global Reinsurance division of Markel Insurance entered into run-off. The following tables have summarized the loss development by product line of the rest of the Markel Insurance segment separate from the Global Reinsurance division. The Company does not estimate losses at the level of aggregation presented within the tables as it offers a diverse portfolio of products and manages these products in more disaggregated groupings.

As a result of the trends and factors described in the tables, the Company's actuaries adjusted their estimates of the ultimate liability for unpaid losses and loss adjustment expenses in the respective periods. For those product lines with favorable development on prior accident years loss reserves, management has now given greater credibility to the favorable trends observed by the Company's actuaries and, upon incorporating these favorable trends into its best estimate, reduced prior years loss reserves accordingly.

In 2023, the unfavorable claims and loss trends experienced on the Company's U.S. general liability and professional liability product lines disrupted the Company's favorable historic claims development trends, reflecting broader market conditions, including the effects of economic and social inflation. In 2024, the Company's U.S. professional liability product lines continued to experience many of these same trends, while the U.S. general liability product lines began to stabilize, resulting in modest favorable development as management gave more credibility to the favorable trends observed by the Company's actuaries. In 2025, while certain of the Company's U.S. professional liability product lines began to stabilize, the Company's run-off risk-managed directors and officers product lines experienced notable adverse development, resulting in net adverse development across the Company's U.S. professional liability product lines.

Consistent with the Company's reserving philosophy, management responds quickly to increase loss reserves following any indication of increased claims frequency or severity in excess of previous expectations, however in instances where trends have been more favorable than previously anticipated, management will wait to reduce loss reserves until those trends are observed over additional periods of time.

d) Historic Loss Development

The following tables present undiscounted loss development information, by accident year, for the Company's Markel Insurance segment, including cumulative incurred and paid losses and allocated loss adjustment expenses, net of reinsurance, as well as the corresponding amount of IBNR reserves as of December 31, 2025. Loss development for the Markel Insurance segment's Global Reinsurance division, which is in run-off, is presented separately from loss development for the rest of the segment. This level of disaggregation is consistent with how the Company analyzes loss reserves for both internal and external reporting purposes. The loss development information for the years ended December 31, 2016 through 2024 is presented as supplementary information. All amounts included in the following tables related to transactions denominated in a foreign currency have been translated into U.S. Dollars using the exchange rates in effect at December 31, 2025.

During 2025, the Company revised and improved the methodology used within its international insurance operations to convert loss reserves established on an underwriting year basis to an accident year basis for financial reporting purposes as part of its implementation of a new data warehousing and reporting system. The new system also provided for improvements in the methodology to allocate changes in estimates of ultimate losses and loss adjustment expenses by underwriting year to accident year.

Upon implementation of the new system, the Company applied the new methodology to its ultimate incurred losses and allocated loss adjustment expenses, which resulted in a change in the accident year allocation of ultimate incurred losses and allocated loss adjustment expenses for financial reporting purposes, including for accident years that are not presented in the tables below. There was no change in the Company's estimate of total ultimate incurred losses and allocated loss adjustment expenses as a result of the application of the new methodology.

The Company has recast prior period amounts for ultimate incurred losses and allocated loss adjustment expenses presented in the following tables to reflect its change in estimate of the allocation of accident year loss reserves in 2025 to the annual periods that gave rise to the change.

The difference between the loss development implied by the tables for the year ended December 31, 2025 and actual losses and loss adjustment expenses recognized on prior accident years is primarily attributed to the fact that amounts presented in these tables exclude amounts attributed to the 2015 and prior accident years. The remaining difference is attributed to the fact that amounts presented in these tables exclude unallocated loss adjustment expenses, as well as differences in the presentation of foreign currency movements, as previously described, none of which are material.

The Markel Insurance segment excluding its Global Reinsurance division table that follows also includes claim count information, by accident year. The Company defines a claim as a single claim incident, per policy, which may include multiple claimants and multiple coverages on a single policy. Claim counts include claims closed without a payment as well as claims where the Company is monitoring to determine if an exposure exists, even if a reserve has not been established. Variability in claim counts in the table is primarily attributable to claim counts on pet health liability, a product which has a high claim frequency and low claim severity. There was an elevated number of claims on this product line in 2018, 2019, and 2020. The related net incurred losses and allocated loss adjustment expenses are not material.

All of the business contained within the Markel Insurance segment's Global Reinsurance division is assumed from other insurance or reinsurance companies, for which the Company does not have access to the underlying claim counts. Further, this business includes both quota share and excess of loss treaty reinsurance, through which only a portion of each reported claim results in losses to the Company. As such, the Company has excluded claim count information from the Global Reinsurance division disclosures.

12. Reinsurance

In reinsurance and retrocession transactions, an insurance or reinsurance company transfers, or cedes, all or part of its exposure in return for a premium. The ceding of insurance does not legally discharge the Company from its primary liability for the full amount of the policies, and the Company will be required to pay the loss and bear collection risk if the reinsurer fails to meet its obligations under the reinsurance or retrocessional agreement. A credit risk exists with ceded reinsurance to the extent that any reinsurer is unable to meet the obligations assumed under the reinsurance or retrocessional contracts. Allowances are established for credit losses expected to be recognized over the life of the reinsurance recoverables.

Underwriting

Within its underwriting operations, the Company uses reinsurance and retrocessional reinsurance to manage its net retention on individual risks and overall exposure to losses while providing it with the ability to offer policies with sufficient limits to meet policyholder needs.

Within the Company's underwriting operations, at December 31, 2025, balances recoverable from the ten largest reinsurers, by group, represented 63% of the $5.8 billion reinsurance recoverables before considering reinsurance allowances and collateral. As of December 31, 2024, balances recoverable from the ten largest reinsurers, by group, represented 63% of the $5.0 billion reinsurance recoverables before considering reinsurance allowances and collateral. At December 31, 2025, the largest reinsurance balance was due from RenaissanceRe and represented 21% of reinsurance recoverables before considering reinsurance allowances and collateral.

Fronting

Within its fronting operations, the Company generally enters into quota share reinsurance agreements whereby the Company cedes to the capacity providers (reinsurers) substantially all of its gross liability under the policies issued by the Company. However, there are certain programs that contain limits on the reinsurers' obligations to the Company that expose the Company to underwriting risk, including loss ratio caps, exclusions of the credit risk of producers, and aggregate reinsurance limits that the Company believes are unlikely to be exceeded. The Company also remains exposed to the credit risk of the reinsurer, or the risk that one of its reinsurers becomes insolvent or otherwise unable or unwilling to pay policyholder claims. This credit risk is generally mitigated by either selecting well capitalized, highly rated authorized capacity providers or requiring that the capacity provider post substantial collateral to secure the reinsured risks, which, in some instances, exceeds the related reinsurance recoverable.

Within the Company's program services operations, at December 31, 2025, balances recoverable from the ten largest reinsurers, by group, represented 63% of the $8.8 billion reinsurance recoverables before considering reinsurance allowances

10K - 106

and collateral. As of December 31, 2024, balances recoverable from the ten largest reinsurers, by group, represented 55% of the $6.0 billion reinsurance recoverables before considering reinsurance allowances and collateral. At December 31, 2025, the largest reinsurance balance was due from Longtail Re and represented 26% of reinsurance recoverables before considering reinsurance allowances and collateral. The reinsurance balance due from Longtail Re, as of December 31, 2025, was fully collateralized.

All of the other business fronted by the Company is on behalf of Nephila; therefore, substantially all of the reinsurance recoverables within these operations are attributable to unconsolidated entities managed by Nephila, which are considered related parties. See note 18.

The following tables summarize the effect of reinsurance and retrocessional reinsurance on premiums written and earned. Fronting premiums are attributable to business written on behalf of third-party capacity providers, substantially all of which are ceded.

In May 2024, the Company issued $600 million of 6.0% unsecured senior notes due May 2054. Net proceeds to the Company were $592.6 million, before expenses. The Company used these proceeds to redeem in full its Series A preferred shares in June 2025. See note 19.

The Company's 7.35% unsecured senior notes due August 15, 2034 are not redeemable. The Company's other unsecured senior notes are redeemable by the Company at any time, subject to payment of a make-whole premium to the noteholders. None of the Company's senior long-term debt is subject to any sinking fund requirements.

The Company's other debt is comprised of debt associated with its operating businesses. As of December 31, 2025 and 2024, other debt at the Company's operating businesses was $271.3 million and $297.4 million, respectively, which includes amounts outstanding on their respective credit facilities. This debt is non-recourse to the holding company and generally is secured by the assets of those operating businesses.

Various of the Company's operating businesses maintain revolving credit facilities or lines of credit, which provide up to $691.5 million of aggregate capacity for working capital and other general operational purposes. A portion of the capacity on certain of these credit facilities may be used as security for letters of credit and other obligations. At December 31, 2025 and 2024, $146.8 million and $150.0 million, respectively, of borrowings were outstanding under these credit facilities. As of December 31, 2025, all of the Company's operating businesses were in compliance with all covenants contained in their respective credit facilities.

The estimated fair value of the Company's senior long-term debt and other debt was $3.9 billion and $3.8 billion at December 31, 2025 and 2024, respectively.

Markel Group and certain insurance subsidiaries maintain a corporate revolving credit facility, which provides up to $300 million of capacity for future acquisitions, investments, and stock repurchases, and for other working capital and general corporate purposes. At the Company's discretion, up to $200 million of the total capacity may be used for letters of credit. The Company may increase the capacity of the facility by up to $200 million subject to obtaining commitments for the increase and certain other terms and conditions. The Company pays interest on balances outstanding under the facility and a utilization fee for letters of credit issued under the facility. The Company also pays a commitment fee (0.18% at December 31, 2025) on the unused portion of the facility based on the Company's leverage ratio as calculated under the credit agreement. The credit agreement includes financial covenants that require that the Company not exceed a maximum debt to capitalization (leverage) ratio and maintain a minimum amount of consolidated net worth, as well as other customary covenants and events of default. Markel Group guarantees the obligations under the facility of the insurance subsidiaries that are also parties to the credit agreement. This facility expires in June 2028. At December 31, 2025 and 2024, the Company had no borrowings outstanding under this revolving credit facility.

At December 31, 2025, the Company had tax credit carryforwards of $61.5 million, the majority of which related to foreign tax credits to be used against U.S. income tax. The Company expects to utilize all tax credit carryforwards before expiration. The earliest any of these credits will expire is 2034.

At December 31, 2025, the Company had deferred tax assets of $18.9 million for U.S. state net operating loss carryforwards and $13.8 million for foreign net operating loss carryforwards, which are available to offset future taxable income in certain U.S. states and foreign jurisdictions, respectively.

The specifics of each plan and the associated benefits vary by operating business, however, each plan is in line with industry standards, local market terms, and conditions of employment for the business.

17. 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 included in the Financial segment. MCIM serves as the insurance manager for Markel CATCo Re Ltd. (MCRe), 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). These entities were placed into run-off in 2019.

In 2025, MCRe completed a novation to transfer its only remaining open reinsurance contract to Markel Bermuda Limited (MBL), a consolidated subsidiary of the Company. Reserves transferred totaled $23.0 million. Following the novation, all preference shares in MCRe and the Markel CATCo Funds were redeemed, with $20.2 million in distributions to noncontrolling interest holders.

Prior to this novation and share redemption, the Company, through its consolidated subsidiaries, held both preference shares and voting shares in MCRe and consolidated MCRe as its primary beneficiary. However, the terms of the MCRe run-off agreement attributed favorable development on loss reserves held by MCRe to MCRe preference shares held by the Markel CATCo Funds, and ultimately to investors in the Markel CATCo Funds. Results attributed to the run-off of MCRe prior to the redemption were included in the Financial segment. For the years ended December 31, 2025, 2024, and 2023, there was $2.9 million, $58.1 million, and $71.5 million respectively, of favorable loss reserve development on the run-off of reinsurance contracts written by MCRe, all of which was included in services and other expenses and attributable to noncontrolling interests.

As of December 31, 2025, there were no remaining assets or liabilities attributed to MCRe. As of December 31, 2024, the Company's consolidated balance sheet included cash, cash equivalents, restricted cash, and cash equivalents attributed to MCRe of $63.2 million, and unpaid losses and loss adjustment expenses of $25.0 million.

18. Related Party Transactions

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

Fund Management

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 insurance markets, Nephila also acts as an insurance manager to certain Bermuda licensed reinsurers and as the managing agent to Lloyd's Syndicate 2357 and Lloyd's Syndicate 2358 (collectively, the Nephila Reinsurers). Neither the Nephila Funds nor the Nephila Reinsurers are consolidated by the Company. Nephila receives management fees for investment and insurance management services based on either the net asset value of the accounts managed or gross premium volume for the underlying risks to which the investors subscribed. For certain funds, Nephila may also receive performance fees based on their annual performance. For the years ended December 31, 2025, 2024, and 2023, total fund management

10K - 114

revenues attributed to unconsolidated entities managed by Nephila were $159.2 million, $94.6 million, and $97.6 million, respectively.

Fronting

The Company's fronting activities, which are provided through the Company's Markel Insurance segment and program services operations, include programs with the Nephila Reinsurers through which the Company writes insurance policies that are fully ceded to the Nephila Reinsurers in exchange for fronting fees. Through these programs, Nephila utilizes certain of the Company's licensed insurance companies to write a portion of its portfolio of U.S. catastrophe-exposed property and specialty risks. Gross premiums written through these programs that were ceded to the Nephila Reinsurers were $1.9 billion, $1.3 billion, and $1.1 billion for the years ended December 31, 2025, 2024, and 2023, respectively.

As of December 31, 2025 and 2024, reinsurance recoverables on the consolidated balance sheets included $496.0 million and $968.9 million, respectively, due from 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. In 2025, the Company commuted a portfolio of ceded reinsurance contracts with certain Nephila Reinsurers. See note 11(a) for further details.

In order for the Nephila Reinsurers to obtain reinsurance protection for a portion of their exposures, the Company also fronts ceded reinsurance contracts, primarily in the form of industry loss warranties, for the Nephila Reinsurers. Through this arrangement, the underlying risk of the Nephila Reinsurers is retroceded back to the Company and then fully ceded to third-party reinsurers. The Company's gross written premiums from the Nephila Reinsurers under this fronting program were $81.5 million and $168.0 million for the years ended December 31, 2025 and 2024, respectively, all of which were ceded to third parties.

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. 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. Beginning on January 1, 2026, the Company's business with Hagerty transitioned to a fronting arrangement, whereby all business written for Hagerty is ceded to Hagerty Re.

22. Statutory Financial Information

a) The following table summarizes statutory capital and surplus for the Company's insurance subsidiaries.


	December 31,
(dollars in thousands)	2025		2024
United States	$	7,427,635	$	6,764,770
United Kingdom	$	1,217,720	$	1,001,574
Bermuda	$	2,707,037	$	2,414,364
Germany	$	201,652	$	171,581

As of December 31, 2025, the Company's actual statutory capital and surplus significantly exceeded the regulatory requirements. As a result, the amount of statutory capital and surplus necessary to satisfy regulatory requirements is not significant in relation to actual statutory capital and surplus.

The following table summarizes statutory net income for the Company's insurance subsidiaries.


	Year Ended December 31,
(dollars in thousands)	2025		2024		2023
United States	$	749,922	$	500,860	$	196,952
United Kingdom	$	272,327	$	62,084	$	116,436
Bermuda	$	332,021	$	614,056	$	484,417
Germany	$	16,758	$	10,075	$	5,543

Amounts presented for the Company's U.S. insurance subsidiaries have been calculated in accordance with prescribed statutory accounting rules. For the Company's international insurance subsidiaries, the regulations that govern the calculation of statutory capital and surplus do not provide requirements for the calculation of net income. Rather, such amounts are reported in accordance with a basis of accounting permitted by their respective regulator. Amounts presented for the Company's U.K., Bermuda, and German insurance subsidiaries have been calculated in accordance with U.K. GAAP, U.S. GAAP, and German GAAP, respectively.

United States

The laws of the domicile states of the Company's U.S. insurance subsidiaries govern the amount of dividends that may be paid to the holding company. Generally, statutes in the domicile states of the Company's U.S. insurance subsidiaries require prior approval for payment of extraordinary, as opposed to ordinary, dividends. As of December 31, 2025, the Company's U.S. insurance subsidiaries could pay up to $739.9 million to the holding company during the following 12 months under the ordinary dividend regulations.

In converting from U.S. statutory accounting principles to U.S. GAAP, typical adjustments include deferral of policy acquisition costs, differences in the calculation of deferred income taxes and the inclusion of net unrealized gains or losses relating to fixed maturity securities in shareholders' equity. The Company does not use any permitted statutory accounting practices that are different from prescribed statutory accounting practices which impact statutory capital and surplus.

United Kingdom

The Company's U.K. insurance subsidiary, Markel International Insurance Company Limited (MIICL), and its Lloyd's managing agent, Markel Syndicate Management Limited (MSM), are authorized by the Prudential Regulation Authority (PRA) and regulated by both the PRA and the Financial Conduct Authority (FCA). The PRA oversees compliance with established periodic auditing and reporting requirements, minimum solvency margins and individual capital assessment requirements under the Solvency II Directive (Solvency II), and imposes dividend restrictions, while both the PRA and the FCA oversee compliance with risk assessment reviews and various other requirements. MIICL is required to give advance notice to the PRA for any transaction or proposed transaction with a connected or related person. MSM is required to satisfy the solvency requirements of Lloyd's. In addition, the Company's U.K. subsidiaries must comply with the United Kingdom Companies Act of 2006, which provides that dividends may only be paid out of profits available for that purpose. Earnings of the Company's U.K. insurance subsidiaries are available for distribution to the holding company to the extent not otherwise restricted.

Bermuda

The Company's Bermuda insurance subsidiary, MBL, is subject to enhanced capital requirements in addition to minimum solvency and liquidity requirements. The enhanced capital requirement is determined by reference to a risk-based capital model that determines a control threshold for statutory capital and surplus by taking into account the risk characteristics of different aspects of the insurer's business. At December 31, 2025, MBL satisfied both the enhanced capital requirements and the minimum solvency and liquidity requirements.

Under the Bermuda Insurance Act, MBL is prohibited from paying or declaring dividends during a fiscal year if it is in breach of its enhanced capital requirement, solvency margin, or minimum liquidity ratio or if the declaration or payment of the dividend would cause a breach of those requirements. If an insurer fails to meet its solvency margin or minimum liquidity ratio on the last day of any financial year, it is prohibited from declaring or paying any dividends during the next financial year without the approval of the Bermuda Monetary Authority (BMA). Further, MBL is prohibited from declaring or paying, in any financial year, dividends of more than 25% of its total statutory capital and surplus as set forth in its previous year's statutory balance sheet unless at least seven days before payment of those dividends it files with the BMA an affidavit stating that it will continue to meet its solvency margin and minimum liquidity ratio. MBL must obtain the BMA's prior approval for a reduction by 15% or more of the total statutory capital as set forth in its previous year's financial statements. In addition, as a long-term insurer, MBL may not declare or pay a dividend to any person other than a policyholder unless the value of the assets in its long-term business fund, as certified by MBL's approved actuary, exceeds the liabilities of its long-term business. The amount of the dividend cannot exceed the aggregate of that excess and any other funds legally available for the payment of the dividend. As of December 31, 2025, MBL could pay up to $676.8 million to the holding company during the following 12 months without making any additional filings with the BMA.

Germany

The Company's German insurance subsidiary, Markel Insurance SE, is regulated by the Federal Financial Conduct Authority in Germany and is also subject to capital and solvency requirements under Solvency II.

b) Lloyd's sets the corporate members' required capital annually based on each syndicates' business plans, rating environment, reserving environment, and input arising from Lloyd's discussions with, among others, regulatory and rating agencies. Such required capital is referred to as Funds at Lloyd's (FAL) and comprises cash and investments. The amount of cash and investments held as FAL as of December 31, 2025 was $1.1 billion. Of this amount, $407.1 million was provided by the holding company and is not available for general use by the Company. The remaining amount, provided by the Company's insurance subsidiaries, is not available for distribution to the holding company. The Company's corporate member may also be required to maintain funds under the control of Lloyd's in excess of its capital requirements and such funds also may not be available for distribution to the holding company.

Item 9A. CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures

As of December 31, 2025, 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.

Management's Report On Internal Control Over Financial Reporting

Management is responsible for establishing and maintaining adequate internal control over financial reporting, as defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act. Our internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles.

Management does not expect that its internal control over financial reporting will prevent all error and all fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Internal control over financial reporting is a process that involves human diligence and compliance and is subject to lapses in judgment and breakdowns resulting from human failures. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, have been detected. The design of any system of internal control over financial reporting also is based in part upon certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

Under the supervision and with the participation of management, including the PEO and the PFO, we evaluated the effectiveness of our internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control - Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation, we have concluded that we maintained effective internal control over financial reporting as of December 31, 2025.

KPMG LLP, our independent registered public accounting firm, has issued an attestation report on the effectiveness of our internal control over financial reporting as of December 31, 2025, which is included herein.

Changes in Internal Control Over Financial Reporting

During the fourth quarter of 2025, Markel Insurance began transitioning open claims within its U.S. insurance operations to a new claims system, which is also being used for new claims. The system modernizes the claims infrastructure, automating and streamlining certain tasks and processes. As part of this transition, we evaluated the impact of the new system on our internal control over financial reporting and added new controls, or made updates to existing controls, as necessary. There were no other changes in our internal control over financial reporting during the fourth quarter of 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM

To the Shareholders and Board of Directors

Markel Group Inc.:

Opinion on Internal Control Over Financial Reporting

We have audited Markel Group Inc. and subsidiaries' (the Company) internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. In our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of December 31, 2025, based on criteria established in Internal Control – Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of December 31, 2025 and 2024, the related consolidated statements of income and comprehensive income, changes in equity, and cash flows for each of the years in the three-year period ended December 31, 2025, and the related notes and financial statement schedules II and III (collectively, the consolidated financial statements), and our report dated February 26, 2026 expressed an unqualified opinion on those consolidated financial statements.

Basis for Opinion

The Company's management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting, included in the accompanying Management's Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company's internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether effective internal control over financial reporting was maintained in all material respects. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audit also included performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company's internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company's internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company's assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
