Generally Accepted Accounting Principles (“GAAP”)

require that we include the changes in unrealized gains (losses) of our equity security investments as a component of investment gains (losses) in our earnings statements. In the table above, investment gains (losses) in 2025 include gains of

$9.6 billion in the fourth quarter and $12.9 billion in the full year and in 2024 include gains of $2.1 billion in the fourth quarter and losses of $38.1 billion in the full year due to changes during the fourth quarter

and the full year in the unrealized gains that existed in our equity security investment holdings. Investment gains (losses) in 2025 also include after-tax realized gains on sales of investments of

$3.9 billion in the fourth quarter and $17.8 billion in the full year and in 2024 include gains of $3.1 billion in the fourth quarter and $79.6 billion in the full year.

The amount of T3investment gains (losses) in any given quarter is usually meaningless and delivers figures for net earnings per share that can be

extremely misleading to investors who have little or no knowledge of accounting rules.

An analysis of Berkshire’s operating earnings follows (dollar amounts are in millions).

Use of Non-GAAP Financial Measures

This press release includes certain non-GAAP financial measures. The reconciliations of such measures to the most

comparable GAAP figures in accordance with Regulation G are included herein.

Berkshire presents its results in the way it believes will be most

meaningful and useful, as well as most transparent, to the investing public and others who use Berkshire’s financial information. That presentation includes the use of certain non-GAAP financial

measures. In addition to the GAAP presentations of net earnings, Berkshire shows operating earnings defined as net earnings exclusive of investment gains (losses), impairments of goodwill and intangible assets and other-than-temporary impairments of

equity method investments.

Although the investment of insurance and reinsurance premiums to generate investment income and investment gains or losses is

an integral part of Berkshire’s operations, the generation of investment gains or losses is independent of the insurance underwriting process. Moreover, as previously described, under applicable GAAP accounting requirements, we are required to

include the changes in unrealized gains/losses of our equity security investments as a component of investment gains/losses in our periodic earnings statements. In sum, investment gains/losses for any particular period are not indicative of

quarterly business performance.

transportation, manufacturing, services and retailing. Common stock of the company is listed on the New York Stock Exchange, trading symbols BRK.A and BRK.B.
