Berkshire Hathaway Inc (BRK-A)

Berkshire Hathaway Inc. is a holding company whose subsidiaries are engaged in numerous diverse business activities, the most important of which are insurance businesses conducted on both a primary and reinsurance basis, a freight rail transportation business, and a group of utility and energy generation and distribution businesses. The company also owns and operates numerous other businesses engaged in a variety of manufacturing, services, and retailing activities. Berkshire's operating subsidiaries are managed on an unusually decentralized basis, with few centralized or integrated business functions. The insurance industry is subject to regulatory oversight throughout the world, and except for regulatory considerations, there are virtually no barriers to entry. Insurers compete based on reliability, financial strength and stability, financial ratings, underwriting consistency, service, business ethics, price, performance, capacity, policy terms, and coverage conditions. The freight rail transportation business is highly competitive, with competition from deregulated motor carriers, other railroads, river barges, ships, and pipelines, and the primary rail competitor in the Western U.S. is Union Pacific Railroad Company. The utility and energy businesses are subject to seasonal variations principally related to the use of electricity for air conditioning and natural gas for heating.

Berkshire's insurance subsidiaries maintain capital strength at exceptionally high levels, which differentiates them from their competitors. The combined statutory surplus of Berkshire's U.S.-based insurers was approximately $333 billion ¹ at December 31, 2025. Berkshire's major insurance subsidiaries are rated AA+ by Standard & Poor's and A++ (superior) by A.M. Best with respect to their financial condition and claims paying ability. GEICO competes for private passenger automobile insurance customers with other companies including State Farm, Progressive, Allstate, and USAA. According to A.M. Best data for 2024 published in 2025, the five largest private passenger automobile insurers had a combined market share of approximately 63.6% ² based on written premiums, with GEICO's market share being the third largest at approximately 11.6% ³. BNSF Railway's primary rail competitor in the Western region of the U.S. is Union Pacific Railroad Company.

Berkshire generates revenue through a highly diversified portfolio of wholly owned operating subsidiaries. The insurance businesses generate revenue from underwriting insurance and reinsurance of property, casualty, life, and health risks worldwide, and from investment income on a large portfolio of publicly traded equity securities, short-term investments, and fixed maturity securities. The freight rail transportation business generates revenue by transporting a range of products and commodities derived from manufacturing, agricultural, and natural resource industries, with freight revenues covered by contractual agreements of varying durations or common carrier published prices. The utility and energy businesses generate revenue from regulated electric and natural gas utility operations serving approximately 5.4 million ⁴ retail customers, interstate natural gas pipeline operations, and other energy businesses including renewable independent power projects. The manufacturing, service, and retailing businesses generate revenue through a wide variety of activities. A significant source of investment funds for the insurance businesses is "float," which represents the approximate net policyholder funds generated through underwriting activities that are held for investment; on a consolidated basis, float has increased from approximately $138 billion ⁵ at the end of 2020 to approximately $176 billion ⁶ at the end of 2025.

Berkshire's insurance underwriting operations include three groups: GEICO, Berkshire Hathaway Primary Group, and Berkshire Hathaway Reinsurance Group. GEICO's principal business is the sale of private passenger automobile insurance to individuals in all 50 states and the District of Columbia, primarily through direct response methods via the Internet or telephone. The Berkshire Hathaway Primary Group is a collection of independently managed insurers that provide a wide variety of insurance coverages to policyholders located principally in the U.S., with nearly 90% ⁷ of BH Primary net premiums written in 2025 in the U.S., of which approximately 40% ⁸ was written on a non-admitted basis. The Berkshire Hathaway Reinsurance Group offers a wide range of coverages on property, casualty, life, and health risks to insurers and reinsurers worldwide and conducts business activities in 23 ⁹ countries. A significant portion of the NICO Group's annual reinsurance premium currently derives from a 20% ¹⁰ quota-share agreement with Insurance Australia Group Limited that expires on December 31, 2029 ¹¹. Berkshire Hathaway Life Insurance Company of Nebraska writes periodic payment annuity insurance policies and reinsures annuity-like obligations, but has not written any new policies since 2022 ¹². Retroactive reinsurance contracts indemnify ceding companies for adverse development of claims from loss events that have already occurred, and no contracts of significance have been written in recent years.

Burlington Northern Santa Fe, LLC operates one of the largest freight rail transportation systems in North America, with approximately 35,000 ¹³ employees at the end of 2025, of whom approximately 30,000 ¹⁴ were members of a labor union. BNSF Railway transports a range of products and commodities, with freight revenues classified into consumer products, industrial products, agricultural and energy products, and coal. Berkshire Hathaway Energy Company has investments in a diversified portfolio of locally managed and operated businesses principally within the energy industry. BHE's domestic regulated energy interests comprise four regulated U.S. utility companies serving approximately 5.4 million ¹⁵ retail customers and five U.S. interstate natural gas pipeline companies with approximately 20,900 ¹⁶ miles of operated pipeline having a design capacity of approximately 21.6 billion ¹⁷ cubic feet of natural gas per day. Other energy businesses include electric transmission and distribution operations in Great Britain and Canada, a diversified portfolio of mostly renewable independent power projects and investments, and a 75% ¹⁸ interest in a liquefied natural gas export, import, and storage facility. BHE also has an investment in a residential real estate brokerage firm in the U.S. and is a franchisor to a large network of residential real estate brokerages in the U.S. BHE employs approximately 24,000 ¹⁹ people. The U.S. utilities collectively own approximately 32,400 ²⁰ net megawatts of generation capacity in operation and under construction.

Berkshire and its operating subsidiaries employed approximately 387,800 ²¹ people worldwide at the end of 2025, of which approximately 80% ²² were in the United States and 19% ²³ were represented by unions. Berkshire's insurance businesses employed approximately 42,600 ²⁴ people at the end of 2025. The combined statutory surplus of Berkshire's U.S.-based insurers was approximately $333 billion ²⁵ at December 31, 2025. On a consolidated basis, float has increased from approximately $138 billion ²⁶ at the end of 2020 to approximately $176 billion ²⁷ at the end of 2025. The aggregate deductible for Berkshire's insurance group under the Terrorism Risk Insurance Program is expected to be approximately $2.5 billion ²⁸ in 2026. BNSF management has committed to a 30% ²⁹ reduction in BNSF Railway's GHG emissions by 2030 from its baseline year of 2018. Consumption of diesel fuel by locomotives accounted for approximately 80% ³⁰ of BNSF Railway's greenhouse gas emissions in its baseline year of 2018.

In 2025, total revenues were $371.470 billion ³¹, compared to $369.694 billion ³² in 2024. Net earnings attributable to Berkshire Hathaway shareholders were $90.898 billion ³³ in 2025, compared to $88.991 billion ³⁴ in 2024. Net earnings per Class A equivalent share were $62,775 ³⁵ in 2025, compared to $60,764 ³⁶ in 2024. Insurance underwriting earnings were $9.022 billion ³⁷ in 2025, compared to $7.837 billion ³⁸ in 2024. Insurance investment income was $13.670 billion ³⁹ in 2025, compared to $10.677 billion ⁴⁰ in 2024.

A significant growth vector for the insurance businesses is the generation of float, which has increased from approximately $138 billion ⁴¹ at the end of 2020 to approximately $176 billion ⁴² at the end of 2025. The cost of float can be measured as the net pre-tax underwriting earnings or loss as a percentage of the average float balance. The insurance businesses expect to achieve an underwriting profit over time, except for retroactive reinsurance and periodic payment annuity products, which generate significant amounts of up-front premiums along with estimated claims expected to be paid over long time periods, creating float. The NICO Group's 20% ⁴³ quota-share agreement with Insurance Australia Group Limited, which expires on December 31, 2029 ⁴⁴, represents a significant source of annual reinsurance premium. BNSF management has committed to a broad sustainability model that is anticipated to result in a 30% ⁴⁵ reduction in BNSF Railway's GHG emissions by 2030 from its baseline year of 2018, with long-term solutions such as battery-electric and hydrogen locomotives being evaluated and field-tested.

The filing does not contain a dedicated section on margin and cost outlook with specific targets or figures.

BNSF Railway intends to continue improvements in fuel efficiency and increased utilization of renewable diesel fuel. Long-term solutions, such as battery-electric and hydrogen locomotives, are also being evaluated and field-tested. BNSF Railway had approximately 35,000 ⁴⁶ employees at the end of 2025, of whom approximately 30,000 ⁴⁷ were members of a labor union. Berkshire and its operating subsidiaries employed approximately 387,800 ⁴⁸ people worldwide at the end of 2025.

The filing does not contain specific figures for R&D spending levels, capital expenditure plans, share repurchase authorization amounts, or dividend policy.

The insurance industry is subject to extensive regulation, and the Terrorism Risk Insurance Program extends to December 31, 2027 ⁴⁹ through the Terrorism Risk Insurance Program Reauthorization Act of 2019. The aggregate deductible for Berkshire's insurance group under TRIA is expected to be approximately $2.5 billion ⁵⁰ in 2026. There is also an aggregate program limit of $100 billion ⁵¹ on the amount of the federal reinsurance coverage for each TRIA year. BNSF's rail operations are subject to extensive federal, state, and local environmental regulations covering discharges, air emissions, toxic substances, and the generation, handling, storage, transportation, and disposal of waste and hazardous materials, which effectively increase the costs and liabilities associated with rail operations. The business environment in which BNSF Railway operates is highly competitive, with deregulated motor carriers and other railroads, as well as river barges, ships, and pipelines, exerting pressure on price and service levels.

The filing does not contain a separate section on structural headwinds and execution risks beyond those discussed in the risk factors and operational context.

The filing does not contain a separate letter to shareholders or a management discussion section that conveys a specific tone or message from management beyond the standard MD&A analysis. The MD&A discusses the overall trajectory of the business, noting that total revenues were $371.470 billion ⁵⁵ in 2025 compared to $369.694 billion ⁵⁶ in 2024, and net earnings attributable to Berkshire Hathaway shareholders were $90.898 billion ⁵⁷ in 2025 compared to $88.991 billion ⁵⁸ in 2024. The strategic priorities emphasized include maintaining the decentralized management philosophy, with operating subsidiaries managed on an unusually decentralized basis and few centralized or integrated business functions. The Chief Executive Officer is ultimately responsible for significant capital allocation decisions and investment activities, as well as evaluating the operating performance of the operating businesses. The Board of Directors is responsible for selecting an appropriate successor to the Chief Executive Officer.

Total revenues were $371.470 billion ⁵⁹ in 2025, compared to $369.694 billion ⁶⁰ in 2024. Net earnings attributable to Berkshire Hathaway shareholders were $90.898 billion ⁶¹ in 2025, compared to $88.991 billion ⁶² in 2024. Net earnings per Class A equivalent share were $62,775 ⁶³ in 2025, compared to $60,764 ⁶⁴ in 2024. Insurance underwriting earnings were $9.022 billion ⁶⁵ in 2025, compared to $7.837 billion ⁶⁶ in 2024. Insurance investment income was $13.670 billion ⁶⁷ in 2025, compared to $10.677 billion ⁶⁸ in 2024. Net earnings of BNSF were $4.577 billion ⁶⁹ in 2025, compared to $4.958 billion ⁷⁰ in 2024. Net earnings of BHE were $2.350 billion ⁷¹ in 2025, compared to $2.292 billion ⁷² in 2024. Manufacturing, service, and retailing businesses' net earnings were $12.868 billion ⁷³ in 2025, compared to $12.478 billion ⁷⁴ in 2024. Investment and derivative contract gains/losses were $68.058 billion ⁷⁵ in 2025, compared to $60.654 billion ⁷⁶ in 2024.

A material risk is the potential for significant losses from catastrophic events, including hurricanes, earthquakes, wildfires, and terrorist acts, which could result in large insurance and reinsurance claims. The Terrorism Risk Insurance Program provides federal reinsurance for certified terrorism losses, with an aggregate program limit of $100 billion ⁵² per TRIA year and an expected aggregate deductible for Berkshire's insurance group of approximately $2.5 billion ⁵³ in 2026. Another significant risk involves the extensive environmental liabilities associated with BNSF's rail operations, which are subject to federal and state statutes that may hold BNSF jointly and severally liable for cleanup costs without regard to fault. BNSF's consumption of diesel fuel by locomotives accounted for approximately 80% ⁵⁴ of its greenhouse gas emissions in its baseline year of 2018, and the company faces regulatory and operational risks related to climate change and emissions reduction targets. The insurance industry is highly competitive with virtually no barriers to entry except for regulatory considerations, and insurers compete based on price, financial strength, and service. Additionally, the company's insurance subsidiaries are subject to extensive state regulation focused on financial solvency, and changes in regulatory requirements or capital standards could impact operations.
