Item 1. Business Description

Berkshire Hathaway Inc. (“Berkshire,” “Company” or “Registrant”) is a holding company owning subsidiaries engaged in numerous diverse business activities. The most important of these are insurance businesses, conducted on both a primary basis and a reinsurance basis, a freight rail transportation business and a group of utility and energy generation and distribution businesses. Berkshire also owns and operates numerous other businesses engaged in a variety of manufacturing, services and retailing activities. Berkshire is domiciled in the state of Delaware, and its corporate headquarters is in Omaha, Nebraska.

Berkshire’s operating subsidiaries are managed on an unusually decentralized basis. There are few centralized or integrated business functions. Berkshire’s Chief Executive Officer is ultimately responsible for significant capital allocation decisions and investment activities. Berkshire’s Chief Executive Officer is also ultimately responsible for evaluating the operating performance of the operating businesses.

Berkshire’s senior corporate management is responsible for establishing and monitoring Berkshire’s corporate governance practices and monitoring governance efforts, including those at the operating businesses, and participating in the resolution of governance-related issues as needed. Berkshire’s Board of Directors is responsible for selecting an appropriate successor to the Chief Executive Officer. The Berkshire Code of Business Conduct and Ethics emphasizes, among other things, the commitment to ethics and compliance with government laws and regulations and provides basic standards for ethical and legal behavior of its employees.

Human capital and resources are an integral and essential component of Berkshire’s businesses. Berkshire and its operating subsidiaries employed approximately 387,800 people worldwide at the end of 2025, of which approximately 80% were in the United States (“U.S.”) and 19% were represented by unions. Employees engage in a wide variety of occupations. Consistent with Berkshire’s decentralized management philosophy, Berkshire’s operating subsidiaries each establish specific policies and practices concerning the attraction and retention of personnel within their organizations. Given the wide variations in the nature and size of business activities, specific policies and practices vary among Berkshire’s operating subsidiaries. Policies and practices commonly address, among other things: maintaining a safe work environment and minimizing or eliminating workplace injuries; offering competitive compensation, which includes various health insurance and retirement benefits, as well as incentives to recognize and reward performance; wellness programs; training, learning and career advancement opportunities; and hiring practices intended to identify qualified candidates. Berkshire’s combined U.S. workforce data, based on U.S. Equal Employment Opportunity Commission guidelines, is available on its website (https://www.berkshirehathaway.com) under sustainability.

Insurance Businesses

Berkshire’s insurance business activities are conducted through numerous domestic and foreign-based insurance subsidiaries. Berkshire’s insurance subsidiaries provide insurance and reinsurance of property and casualty risks as well as life and health risks worldwide. Berkshire’s insurance businesses employed approximately 42,600 people at the end of 2025. For purposes of this discussion, entities that provide insurance or reinsurance are referred to as insurers.

In direct or primary insurance activities, the insurer assumes the risk of loss from people or organizations that are directly subject to the risks. Such risks may relate to property, casualty (or liability), life, accident, health, financial or other perils that arise from an insurable event. In reinsurance activities, the insurer assumes defined portions of risks that other direct insurers or reinsurers assumed in their own insuring activities.

Insurance and reinsurance are generally subject to regulatory oversight throughout the world. Except for regulatory considerations, there are virtually no barriers to entry into the insurance and reinsurance industry. Competitors may be domestic or foreign, as well as licensed or unlicensed. The number of competitors within the industry is not known. Insurers compete based on reliability, financial strength and stability, financial ratings, underwriting consistency, service, business ethics, price, performance, capacity, policy terms and coverage conditions.

K-1

Insurers based in the U.S. are subject to regulation by their states of domicile and by those states in which they are licensed to write policies on an admitted basis. The primary focus of state regulation is to monitor financial solvency of insurers and otherwise protect policyholder interests. States establish minimum capital levels for insurance companies and establish guidelines for permissible business and investment activities and have the authority to suspend or revoke a company’s authority to do business. States regulate the payment of shareholder dividends by insurance companies and other transactions with affiliates.

Insurers that market, sell and service insurance policies in the states where they are licensed are referred to as admitted insurers. Admitted insurers are generally required to obtain regulatory approval of their policy forms and/or premium rates. Non-admitted insurance markets have developed to provide insurance that is otherwise unavailable through admitted insurers. Non-admitted insurance, often referred to as “excess and surplus” lines, is procured by either state-licensed surplus lines brokers who place risks with insurers not licensed in that state or by the insured party’s direct procurement from non-admitted insurers. Non-admitted insurance is subject to considerably less regulation with respect to policy rates and forms. Reinsurers are normally not required to obtain regulatory approval of premium rates or reinsurance contracts.

The insurance regulators of every state participate in the National Association of Insurance Commissioners (“NAIC”). The NAIC adopts forms, instructions and accounting procedures for use by U.S. insurers in preparing and filing annual statutory financial statements. In addition, the NAIC develops or adopts statutory accounting principles, model laws, regulations and programs dealing with regulatory oversight of solvency, risk management, compliance with financial regulation standards and risk-based capital reporting requirements. However, an insurer’s state of domicile has ultimate authority over these solvency and soundness related matters, and the laws and regulations implemented in individual states may differ from those adopted by the NAIC.

International insurance regulators, through the International Association of Insurance Supervisors (“IAIS”), have been developing advisory standards and best practices focused on establishing a common set of principles (“Insurance Core Principles”) and framework (“ComFrame”) for the regulation of large multi-national insurance groups. The Insurance Core Principles and ComFrame cover a wide range of topics, including group-wide supervision by regulators, corporate governance, risk management, capital adequacy and other macroprudential issues. As part of ComFrame, the IAIS adopted an international capital standard (“ICS”) for internationally active insurance groups in December 2024.

While the IAIS standards do not have legal effect, U.S. state insurance departments and the NAIC are implementing various group supervision regulatory tools and mandates that are responsive to certain IAIS standards. U.S. state regulators have formed supervisory colleges intended to promote communication and cooperation amongst the various domestic and international insurance regulators. U.S. state regulators require insurance groups to file an annual report and an Own Risk Solvency Assessment

Item 1A. Risk Factors

Berkshire and its subsidiaries (referred to herein as “we,” “us,” “our” or similar expressions) are subject to certain risks and uncertainties in its business operations which are described below. The risks and uncertainties described below are not the only risks we face. Additional risks and uncertainties that are presently unknown or are currently deemed immaterial may also impair our business operations.

General Business Risks

Terrorist acts could hurt our operating businesses.

A nuclear, biological or chemical terrorist attack or armed terrorist incursions could produce significant losses to our worldwide operations. Our business operations could be adversely affected from such acts through the loss of human life, destruction of production facilities and information systems or other property damage. We share these risks with all businesses.

Cybersecurity risks could result in economic losses to our businesses and reputational damage.

We rely on technology in virtually all aspects of our business. Like those of many large businesses, certain of our information systems have been subject to cyber threats, including computer viruses, malicious codes, unauthorized access, phishing efforts, denial-of-service attacks and other cyber-attacks. We expect continued exposure to such attacks in the future and attacks have become more sophisticated and frequent. A significant disruption or failure of our technology systems could result in service interruptions, safety failures, security events, regulatory compliance failures, an inability to protect information and assets against unauthorized users and other operational difficulties. Cyber-attacks perpetrated against our systems could result in loss of assets and critical information and expose us to remediation costs and reputation damage.

K-24

Although we have taken steps intended to mitigate these risks, including business continuity planning, disaster recovery planning and business impact analysis, a significant disruption or cyber intrusion at one or more of our significant operations could adversely affect our results of operations, financial condition and/or liquidity. Additionally, if we are unable to acquire, develop, implement, adopt or protect rights around new technology, we may suffer a competitive disadvantage, which could also have an adverse effect on our results of operations, financial condition and/or liquidity.

Cyber-attacks could further adversely affect our ability to operate our facilities, information technology and business systems or could compromise confidential company, customer and employee information. Political, economic, social or financial market instability or damage to or interference with our operating assets, customers or suppliers from cyber-attacks may result in business interruptions, lost revenues, higher commodity prices, disruption in fuel supplies, lower energy consumption, unstable markets, increased security, repairs and other costs, including penalties and legal proceedings, or may materially adversely affect us in ways that cannot be predicted at this time. Any of these risks could materially affect our consolidated financial results. Furthermore, instability in the financial markets resulting from terrorism, sustained or significant cyber-attacks or war could also have a material adverse effect on our ability to raise capital. We share these risks with all businesses.

Geopolitical events could cause losses to our business and losses in the values of securities we own.

We believe risks of adverse effects from geopolitical events are rising, through armed and diplomatic conflicts involving governments in various parts of the world. Government policies and actions taken in the U.S. and elsewhere, including responses of other governments to such actions may adversely affect our operating businesses through reduced sales, increased operating costs or sanctions, restricted supply chains, physical damage to our properties and loss of life of our employees and losses in the values of the securities we own. In addition, international trade policies in the U.S. and elsewhere, including tariffs and other barriers, could negatively impact our operating results. We share these risks with all businesses.

We are dependent on a few key people for our major investment and capital allocation decisions.

In May 2025, Berkshire’s Board of Directors appointed Mr. Gregory E. Abel to succeed Mr. Warren E. Buffett as Chief Executive Officer effective January 1, 2026. Major capital allocation and investment decisions are the responsibility of Mr. Abel. Mr. Ajit Jain is Vice Chairman of Berkshire’s insurance operations. Mr. Adam Johnson is President of Berkshire’s Consumer Products, Service and Retailing operations. Mr. Jain and Mr. Johnson each report directly to Mr. Abel.

If for any reason the services of our key personnel were to become unavailable, there could be a material adverse effect on our operations. The Board continually monitors this risk. We believe that the Board’s succession plans, together with the outstanding managers running our numerous highly diversified operating units, helps to mitigate this risk.

We need qualified personnel to manage and operate our various businesses.

In our decentralized business model, 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 Berkshire as a whole. Further, labor disruptions or strikes at our subsidiaries, our customers or within our supply chains could reduce our sales, increase our costs and negatively impact our periodic operating results.

Investments are unusually concentrated in equity securities and fair values are subject to loss in value.

We concentrate a high percentage of the equity security investments of our insurance subsidiaries in relatively small number of issuers. A significant decline in the fair values of our larger investments in equity securities may produce a material decline in our consolidated shareholders’ equity and our consolidated earnings.

Since a large percentage of our equity securities are held by our insurance subsidiaries, significant decreases in the fair values of these investments will produce significant declines in the statutory surplus of our insurance subsidiaries. Our large statutory surplus is a competitive advantage, and a long-term material decline could have an adverse effect on our claims-paying ability ratings and our ability to write new insurance business, thus potentially reducing our future underwriting profits.

K-25

Competition and technology may erode our business franchises and result in lower earnings.

Each of our operating businesses faces intense competition within markets in which they operate. While we manage our businesses with the objective of achieving long-term sustainable growth by developing and strengthening competitive advantages, many factors, including technological changes, disruptive innovations and difficulties in enforcing, protecting and defending our intellectual properties, may erode or prevent the strengthening of competitive advantages. Accordingly, our future operating results will depend to some degree on our operating units successfully protecting and enhancing their competitive advantages. If our operating businesses are unsuccessful in these efforts, our periodic operating results in the future may decline.

Unfavorable general economic conditions may significantly reduce our operating earnings and impair our ability to access capital markets at a reasonable cost.

Our operating businesses are subject to normal economic cycles affecting the general economy or the specific industries in which they operate. Significant deteriorations of economic conditions, including significant inflation over prolonged time periods could produce a material adverse effect on one or more of our significant operations. In addition, our utilities and energy businesses and our railroad business regularly utilize debt as a component of their capital structures and depend on having access to borrowed funds through the capital markets at reasonable rates. To the extent that access to the capital markets is restricted or the cost of funding increases, these operations could be adversely affected.

Epidemics, pandemics or other similar outbreaks could hurt our operating businesses.

The outbreak of epidemics, pandemics or other similar outbreaks in the future may adversely affect our operations, including the value of our equity securities portfolio. This may be due to closures or restrictions requested or mandated by governmental authorities, disruption to supply chains and workforce, reduction of demand for our products and services, credit losses when customers and other counterparties fail to satisfy their obligations to us, and volatility in global equity securities markets, among other factors. We share most of these risks with all businesses.

Regulatory changes may adversely impact our future operating results.

Over time, regulatory initiatives have been adopted in the United States and elsewhere for a variety of reasons, including as responses to financial markets crises, global economic recessions, and social and environmental issues. Such initiatives address, for example, the regulation of banks and other major financial institutions, the regulation of products and services and environmental and climate change matters and income tax policy. These initiatives impact each of our businesses, albeit in varying ways. Increased regulatory compliance costs could have a significant negative impact on our operating businesses, as well as on the businesses in which we have significant, but not controlling, economic interests. We cannot predict whether such initiatives will have a material adverse impact on our consolidated financial position, results of operations or cash flows.

Data privacy and artificial intelligence laws and regulations have been enacted or are under development in various jurisdictions in the U.S. and throughout the world. These regulations address numerous aspects related to the security of personal information that is stored in our information systems, networks and facilities and the use of artificial intelligence tools. Failure to comply with these increased laws and regulations could result in reputation damage and significant economic penalties.

Climate change and the regulation of greenhouse gas (“GHG”) emissions may impact our businesses.

Climate and weather-related events and the regulation of GHG emissions could impact our businesses to varying degrees. Climate-related events, including hurricanes, floods, wildfires, and other extreme weather events may increase the physical risks and impacts to our operations. An increase in the frequency or intensity of extreme weather events and storms could negatively impact the physical assets of our non-insurance operations and could produce losses affecting our businesses. Similarly, extreme weather events may produce losses affecting our insurance operations, as their primary business is to monitor, assess and price risk, including climate-related risk, at an expected economic profit to address the risk-transfer needs of their insurance customers.

Additional GHG and climate-related policies, including legislation, may emerge that influence the transition to a lower GHG-emitting economy and could, in turn, influence costs for our businesses to comply with those policies, including BNSF and BHE, which combined represent the vast majority of Berkshire’s direct emissions. The failure to comply with new or existing regulations or reinterpretation of existing regulations relating to climate change could have a significant adverse effect on our financial results.

K-26

Risks unique to our regulated businesses

Our tolerance for underwriting risk assumed in our various insurance businesses may result in significant underwriting losses.

When properly paid for the risk assumed, we have been and will continue to be willing to assume more risk from a single event than any other insurer has knowingly assumed. Accordingly, we could incur a significant loss from a single catastrophe event resulting from a natural disaster or man-made catastrophes such as terrorism or cyber-attacks. We employ various disciplined underwriting practices intended to mitigate potential losses, attempt to consider all possible correlations and avoid writing groups of policies from which pre-tax losses from a single catastrophe event might aggregate in excess of $15 billion. However, despite our efforts, it is possible that losses could manifest in ways that we do not anticipate and that our risk mitigation strategies are not designed to address. Various provisions of our policies, negotiated to limit our risk, such as limitations or exclusions from coverage, may not be enforceable in the manner we intend, as it is possible that a court or regulatory authority could nullify or void an exclusion or limitation, or legislation could be enacted modifying or barring the use of these exclusions and limitations. Our tolerance for significant insurance losses may result in lower reported earnings in a future period.

The principal cost associated with the property and casualty insurance business is claims. In writing property and casualty insurance policies, we receive premiums today and promise to pay covered losses in the future. However, it will take decades before all claims that have occurred as of any given balance sheet date will be settled. Although we believe that recorded liabilities for unpaid losses are adequate, we will not know whether these liabilities or the premiums charged for the coverages provided were sufficient until well after the balance sheet date. Estimating insurance claim costs is inherently imprecise. It is possible that significant claims may emerge or develop in the future from the policies we have written in the past.

As industry practices and legal, social and environmental conditions evolve, unexpected and unintended issues related to claims and coverage may emerge, including new or expanded theories of liability, increased frequency of litigation driven, in part, by the increasing trend of third-party litigation funding, and other social inflation trends such as juries awarding increasingly larger verdicts. These or other changes could impose new financial obligations on us by extending coverage beyond our underwriting intent and result in increased litigation costs and adverse judicial awards. In some instances, these changes may not become apparent until sometime 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. Our estimated unpaid losses arising under contracts covering property and casualty insurance risks are large ($151.8 billion at December 31, 2025), and a small percentage increase to those liabilities can result in a material reduction in reported earnings.

Changes in regulations and regulatory actions can adversely affect our operating results and our ability to allocate capital.

Our insurance businesses are subject to regulation in the jurisdictions in which we operate. Such regulations may relate to, among other things, the types of business that can be written, the rates that can be charged for coverage, the level of capital that must be maintained and restrictions on the types and size of investments that can be made. Regulations may also restrict the timing and amount of dividend payments to Berkshire by these businesses. U.S. state insurance regulators and international insurance regulators are also actively developing various regulatory mechanisms to address the regulation of large internationally active insurance groups, including regulations concerning group capital, liquidity, governance and risk management. Accordingly, changes in regulations related to these or other matters or regulatory actions imposing restrictions on our insurance businesses may adversely impact our results of operations and restrict our ability to allocate capital.

Our railroad business conducted through BNSF is also subject to a significant number of laws and regulations with respect to rates and practices, taxes, railroad operations and a variety of health, safety, labor, environmental and other matters. Failure to comply with applicable laws and regulations could have a material adverse effect on BNSF’s business. Governments may change the legislative and/or regulatory framework within which BNSF operates, without providing any recourse for any adverse effects that the change may have on the business. Complying with legislative and regulatory changes may pose significant operating and implementation risks and require significant capital expenditures. BNSF can be exposed to significant litigation costs and losses arising from these matters and from ongoing business operations.

K-27

BNSF derives significant revenues from the transportation of energy-related commodities, including coal. Changes in government policies that limit, restrict or displace coal as a fuel source in generating electricity, or limit or restrict other commodities that BNSF transports, could adversely affect revenues and earnings. As a common carrier, BNSF is also required to transport toxic inhalation hazard chemicals and other hazardous materials. The release of hazardous materials could expose BNSF to significant claims, losses, penalties and environmental remediation obligations. Changes in the regulation of the rail industry could negatively impact BNSF’s ability to determine prices for rail services and to make capital improvements to its rail network, resulting in an adverse effect on our results of operations, financial condition and/or liquidity.

The U.S. freight transportation infrastructure is integrated. BNSF’s operations may be negatively affected by service disruptions of other entities, such as ports, passenger trains, and other railroads, which interchange with BNSF Railway. A prolonged service disruption at any of these entities could have adverse consequences on BNSF. Significant consolidation or integration involving participants within the freight transportation industry, including mergers among major rail carriers, may lead to operational disruptions across the rail network and broader supply chain, which could negatively impact BNSF’s operating results, financial condition and liquidity.

Our utilities and energy businesses operated under BHE are highly regulated by numerous federal, state, local and foreign governmental authorities in the jurisdictions in which they operate. These laws and regulations are complex, dynamic and subject to new interpretations or change. Regulations affect almost every aspect of our utilities and energy businesses. Regulations broadly apply and may limit management’s ability to independently make and implement decisions regarding numerous matters including: acquiring businesses; constructing, acquiring, disposing or retiring of operating assets; operating and maintaining generating facilities and transmission and distribution system assets; complying with pipeline safety and integrity and environmental requirements; setting rates charged to customers; establishing capital structures and issuing debt; managing and reporting transactions between our domestic utilities and our other subsidiaries and affiliates; and paying dividends or similar distributions. Failure to comply with or reinterpretations of existing regulations and new legislation or regulations, such as those relating to air quality, climate change, emissions performance standards, water quality, coal ash disposal and other environmental matters, or changes in the nature of the regulatory process may have a significant adverse impact on our financial results. Furthermore, our regulated energy subsidiaries are exposed to losses arising from wildfires and related litigation and judicial outcomes. The energy rates charged by our regulated energy subsidiaries to customers are based on the costs of the business and require regulatory approval. To the extent costs are not recoverable through approved rates, the operating results and financial condition of these businesses can be negatively impacted, perhaps materially.

BNSF requires significant ongoing capital investment to improve and maintain its railroad network so that transportation services can be safely and reliably provided to customers on a timely basis. BHE also requires significant capital to construct, operate and maintain generation, transmission and distribution systems to meet their customers’ needs and reliability criteria. System assets need to be operational for long periods of time to justify the financial investment. The operational or financial failure of capital projects may not be recoverable through rates that are charged to customers. Further, a significant portion of costs of capital improvements may be funded through debt. Restricted access to debt capital markets by BNSF or BHE could adversely affect the results of operations, liquidity and/or capital resources of these businesses.

Item 1C. Cybersecurity

Berkshire recognizes that maintaining processes for identifying, assessing, and managing cybersecurity threats is important in dealing with its significant business risks. As such, Berkshire has implemented a framework for cybersecurity and cyber-related information management across Berkshire’s diverse groups of businesses. The framework permits each Berkshire Business Group (“Business Group”) to tailor solutions to identify, manage, and mitigate risks based on their own assessment of their unique cybersecurity risks in conjunction with each Business Group’s overall risk management processes. At the same time, the framework helps enable consistent and appropriate compliance in reporting material cyber events and risks across Berkshire.

Each Business Group’s Chief Information Security Officer (“CISO”) on at least an annual basis is to provide a report to the Business Group’s senior management, regarding the state of their cybersecurity program and its material cyber risks. These reports are also shared with Berkshire’s internal audit group to inform and enhance the overall risk management processes. In addition, each Business Group is required to maintain an incident reporting process to report significant cybersecurity events to Berkshire. Berkshire and its Business Groups engage and partner with a wide range of third parties to assess, audit, educate, implement, operate, protect, and remediate various cybersecurity related elements.

K-28

Berkshire and its Business Groups rely on third-party service providers for a variety of products and services to run their information systems. This dependence exposes Berkshire and the Business Groups, along with others who use these service providers, to the impact of a cyber-attack on their service providers. On occasion, a cyber-attack on a third-party service provider could have a significant financial, operational or reputational impact to Berkshire. Berkshire and its Business Groups continuously monitor the risks associated with its service providers.

The Audit Committee of Berkshire’s Board of Directors has responsibility for oversight of Berkshire’s cybersecurity risk management program. The Audit Committee receives periodic reports regarding the number of and impact from cybersecurity incidents reported through Berkshire’s cybersecurity incident reporting process. Additionally, the Audit Committee is updated on cybersecurity trends and related issues. Furthermore, the Audit Committee approves and receives updates on the workplan performed by Berkshire’s internal audit group that focuses on information technology and cybersecurity risks. This includes audit procedures related to internal and external penetration testing, attack simulations, vulnerability assessments, cybersecurity program reviews and other audits designed to investigate specific risks. The frequency of these updates is determined by the Audit Committee in conjunction with Berkshire’s senior management.

In addition to the Audit Committee’s oversight, the senior management of Berkshire’s Businesses Groups are responsible for the day-to-day operations of protecting their businesses’ information systems. Each Business Group is required to report significant cybersecurity events to Berkshire. Berkshire’s senior management reviews incident reports to determine whether a cyber incident report should be filed with the SEC.

Item 2. Description of Properties

Item 3. Legal Proceedings

Berkshire and its subsidiaries are parties in a variety of legal actions that routinely arise out of the normal course of business, including legal actions seeking to establish liability directly through insurance contracts or indirectly through reinsurance contracts issued by Berkshire subsidiaries. Plaintiffs occasionally seek punitive or exemplary damages. We do not believe that such normal and routine litigation will have a material effect on our financial condition or results of operations.

Reference is made to Note 27 to the accompanying Consolidated Financial Statements for information concerning certain litigation involving Berkshire subsidiaries. Berkshire and certain of its subsidiaries are also involved in other kinds of legal actions, some of which assert or may assert claims or seek to impose fines and penalties. We currently believe that any liability that may arise from other pending legal actions will not have a material effect on our consolidated financial condition or results of operations.

Item 4. Mine Safety Disclosures

Information regarding the Company’s mine safety violations and other legal matters disclosed in accordance with Section 1503(a) of the Dodd-Frank Reform Act is included in Exhibit 95 to this Form 10-K.

FORWARD-LOOKING STATEMENTS

Investors are cautioned that certain statements contained in this document as well as some statements in periodic press releases and some oral statements of Berkshire officials during presentations about Berkshire or its subsidiaries are “forward-looking” statements within the meaning of the Private Securities Litigation Reform Act of 1995 (the “Act”). Forward-looking statements include statements which are predictive in nature, which depend upon or refer to future events or conditions, or which include words such as “expects,” “anticipates,” “intends,” “plans,” “believes,” “estimates” or similar expressions. In addition, any statements concerning future financial performance (including future revenues, earnings or growth rates), ongoing business strategies or prospects and possible future Berkshire actions, which may be provided by management, are also forward-looking statements as defined by the Act. Forward-looking statements are based on current expectations and projections about future events and are subject to risks, uncertainties and assumptions about Berkshire and its subsidiaries, economic and market factors and the industries in which we do business, among other things. These statements are not guarantees of future performance and we have no specific intention to update these statements.

Actual events and results may differ materially from those expressed or forecasted in forward-looking statements due to a number of factors. The principal risk factors that could cause our actual performance and future events and actions to differ materially from such forward-looking statements include, but are not limited to, changes in market prices of our investments in equity securities; the occurrence of one or more catastrophic events, such as an earthquake, hurricane, geopolitical conflict, act of terrorism or cyber-attack that causes losses insured by our insurance subsidiaries and/or losses to our business operations; the frequency and severity of epidemics, pandemics or other outbreaks, and other events that negatively affect our operating results and restrict our access to borrowed funds through the capital markets at reasonable rates; changes in laws or regulations affecting our insurance, railroad, utilities and energy and finance subsidiaries; changes in federal income tax laws; and changes in general economic and market factors that affect the prices of securities or the industries in which we do business.

Market Information

Berkshire’s Class A and Class B common stock are listed for trading on the New York Stock Exchange, trading symbols: BRK.A and BRK.B, respectively.

Shareholders

Berkshire had approximately 950 record holders of its Class A common stock and 16,500 record holders of its Class B common stock at February 13, 2026. Record owners included nominees holding at least 296,000 shares of Class A common stock and 1,385,000,000 shares of Class B common stock on behalf of beneficial-but-not-of-record owners.

Dividends

Berkshire has not declared a cash dividend since 1967.

Common Stock Repurchase Program

In 2025, Berkshire’s common stock repurchase program was amended to permit Berkshire to repurchase its Class A and Class B common stock at any time that Berkshire’s Chief Executive Officer, after consultation with the Chairman of the Board, believes that the repurchase price is below Berkshire’s intrinsic value, conservatively determined. Prior to the amendment, the program permitted Warren Buffett, Berkshire’s Chairman of the Board of Directors and Chief Executive Officer, to repurchase Berkshire’s common stock under the same criteria. Repurchases may be in the open market or through privately negotiated transactions. No Class A or Class B shares were repurchased in the fourth quarter of 2025.

** The program does not specify a maximum number of shares to be repurchased or obligate Berkshire to repurchase any specific dollar amount or number of Class A or Class B shares and there is no expiration date to the repurchase program. Berkshire will not repurchase its common stock if the repurchases reduce the value of Berkshire’s consolidated cash, cash equivalents and U.S. Treasury Bills holdings to less than $30 billion.*

Through our subsidiaries, we engage in numerous diverse business activities. The business segment data (Note 26 to the accompanying Consolidated Financial Statements) should be read in conjunction with this discussion.

Our periodic operating results may be affected in future periods by the impacts of ongoing macroeconomic and geopolitical conflicts and events, including tensions from developing international trade policies and tariffs, as well as changes in industry or company-specific factors or events. Considerable uncertainty remains as to the ultimate outcome of these events. We are currently unable to reliably predict the ultimate impact on our businesses, whether through changes in the availability of products, supply chain costs and efficiency, and customer demand for our products and services. It is reasonably possible there could be adverse consequences on our operating businesses, as well as on our investments in equity securities, which could significantly affect our future results.

Insurance underwriting generated after-tax earnings of $7.3 billion in 2025, $9.0 billion in 2024 and $5.4 billion in 2023. The comparative earnings decline in 2025 reflected lower earnings from each of our underwriting groups. Overall underwriting results over the past three years were exceptional compared to results over longer periods. However, earnings may decline in the future from the ongoing impacts of competition within the industry and rising claim cost trends. After-tax losses from significant catastrophe events were approximately $850 million in 2025, $1.2 billion in 2024 and $725 million in 2023.

After-tax earnings from insurance investment income declined $1.2 billion (8.5%) in 2025 versus 2024, reflecting lower interest income, attributable to lower interest rates, and dividend income. Insurance investment income increased $4.1 billion in 2024 compared to 2023, driven by higher interest income from short-term investments. Insurance investment income in 2025 was impacted by the effects of large capital distributions to Berkshire at the end of 2024. The income earned on investments (primarily U.S. Treasury Bills) held by Berkshire is included in “other” earnings in the preceding table.

After-tax earnings of BNSF increased 8.8% in 2025 and declined 1.1% in 2024, compared to the corresponding prior year. The increase in 2025 was primarily attributable to lower operating expenses, attributable to improved operating efficiencies, lower litigation accruals, the effect of a charge in 2024 from a labor agreement and a lower effective income tax rate. Earnings in 2024 benefited from higher unit volume, improvements in employee productivity and lower other operating costs, and were negatively impacted by charges in 2024 related to a labor agreement in the fourth quarter and litigation accruals.

After-tax earnings of BHE increased $249 million (6.7%) in 2025 compared to 2024 and $1.4 billion in 2024 compared to 2023. The earnings increase in 2025 reflected lower wildfire loss accruals at PacifiCorp, reduced earnings attributable to noncontrolling interests and the impact of real estate brokerage business litigation accruals in 2024, partially offset by lower earnings from the natural gas pipelines and other energy businesses. The increase in 2024 was primarily due to lower wildfire loss accruals and lower earnings attributable to noncontrolling interests, partially offset by real estate brokerage business litigation accruals.

Earnings from our manufacturing, service and retailing businesses increased 4.4% in 2025 compared to 2024 and decreased 2.2% in 2024 compared to 2023. Results among our numerous operations in 2025 were mixed, with overall earnings increases in our manufacturing and services businesses and lower earnings from the retailing businesses. The earnings decline in 2024 reflected lower earnings from our service and retailing businesses, partially offset by an overall increase from our manufacturing businesses.

Management’s Discussion and Analysis

Results of Operations

Investment gains (losses) can include significant unrealized gains and losses from changes in market prices of our investments in equity securities and in foreign currency exchange rates applicable to certain of our investments. We believe that investment gains and losses, whether realized from dispositions or unrealized from changes in market prices and exchange rates, are generally meaningless in understanding our reported periodic results or evaluating our periodic economic performance. These gains and losses have caused and will continue to cause significant volatility in our periodic earnings. Investment gains in 2023 also included an after-tax non-cash remeasurement gain of approximately $2.4 billion related to our previously held 38.6% interest in Pilot through the application of the acquisition accounting method.

We recorded other-than-temporary impairment losses in 2025 on our investments in The Kraft Heinz Company (“Kraft Heinz”) and Occidental Petroleum Corporation (“Occidental”) common stock, which are accounted for under the equity method. See Note 5 to the accompanying Consolidated Financial Statements.

After-tax other earnings include investment income not allocated to operating businesses, earnings from equity method investments (excluding the previously mentioned other-than-temporary impairment losses recognized on equity method investments), foreign currency exchange rate gains and losses related to Berkshire and BHFC non-U.S. Dollar denominated debt and goodwill impairment losses. After-tax other earnings in 2025 declined $1.3 billion compared to 2024, reflecting after-tax foreign currency exchange rate losses in 2025 of $642 million compared to after-tax gains in 2024 of $1.15 billion, reduced earnings from equity method investments and increased goodwill impairment losses, partially offset by increased investment income.

Insurance—Underwriting

Our periodic underwriting earnings may be subject to considerable volatility from the timing and magnitude of significant property catastrophe loss events. We currently consider consolidated pre-tax losses exceeding $150 million from an event occurring in the current year to be significant. We incurred significant losses from the Southern California wildfires in 2025, Hurricanes Helene and Milton in 2024 and storms and/or floods in New Zealand and Italy in 2023. Changes in estimates for unpaid losses and loss adjustment expenses (“LAE”), including amounts established for occurrences in prior years, and foreign currency transaction gains and losses arising from the remeasurement of non-functional currency denominated assets and liabilities can also significantly affect our periodic underwriting results.

Management’s Report on Internal Control Over Financial Reporting

Management of Berkshire Hathaway Inc. is responsible for establishing and maintaining adequate internal control over financial reporting, as such term is defined in the Securities Exchange Act of 1934 Rule 13a-15(f). Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of the Company’s internal control over financial reporting as of December 31, 2025, as required by the Securities Exchange Act of 1934 Rule 13a-15(c). In making this assessment, we used the criteria set forth in the framework in Internal Control—Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission. Based on our evaluation under the framework in Internal Control—Integrated Framework (2013), our management concluded that our internal control over financial reporting was effective as of December 31, 2025.

The effectiveness of our internal control over financial reporting as of December 31, 2025 has been audited by Deloitte & Touche LLP, an independent registered public accounting firm, as stated in their report which appears on page K-64.

REPORT OF INDEPENDENT REGIST****ERED PUBLIC ACCOUNTING FIRM

To the Shareholders and the Board of Directors of

Berkshire Hathaway Inc.

Opinions on the Financial Statements and Internal Control over Financial Reporting

We have audited the accompanying consolidated balance sheets of Berkshire Hathaway Inc. and subsidiaries (the “Company”) as of December 31, 2025 and 2024, the related consolidated statements of earnings, comprehensive income, changes in shareholders’ equity, and cash flows, for each of the three years in the period ended December 31, 2025, and the related notes (collectively referred to as the “financial statements”). We also have audited 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 (COSO).

In our opinion, the financial statements referred to above 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 three years in the period ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America. Also, 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 COSO.

Basis for Opinions

The Company’s management is responsible for these financial statements, 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 these financial statements and an opinion on the Company’s internal control over financial reporting based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (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 audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audits of the financial statements included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures to respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the 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 financial statements. 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 audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

Critical Audit Matters

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

Unpaid Losses and Loss Adjustment Expenses — Refer to Notes 1 and 16 to the financial statements

Critical Audit Matter Description

The Company’s unpaid losses and loss adjustment expenses (“claim liabilities”) include short duration property and casualty insurance and reinsurance contracts. Key assumptions affecting certain of these claim liabilities include anticipated claims and their severity, expected loss ratios, and expected patterns of paid and incurred losses.

Given the subjectivity of estimating these key assumptions, performing audit procedures to evaluate whether certain of these claim liabilities were appropriately recorded as of December 31, 2025 required a high degree of auditor judgment and an increased extent of effort, including the need to involve our actuarial specialists.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the key assumptions affecting certain of these claim liabilities included the following, among others:

We tested the operating effectiveness of controls over claim liabilities, including those over the key assumptions.

We tested the underlying data that served as the basis for the actuarial analysis to evaluate that the inputs to the actuarial estimate were accurate and complete.

With the assistance of our actuarial specialists:

We developed independent estimates of the claim liabilities, including loss data and industry claim development factors as needed, and compared our estimates to management’s estimates.

We compared prior year estimates of expected incurred losses to actual experience during the most recent year to identify potential bias in management’s determination of the claim liabilities.
