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, T2investment gains (losses) in 2025

include gains of $1.5 billion in the second quarter and losses of $5.9 billion in the first six months and in 2024 include losses of $28.2 billion in the second quarter and $37.9 billion in the first six months due tochanges during the second quarter and the first six months in the unrealized gains that existed in our equity security investment holdings. Investment gains (losses) in 2025 also includeafter-tax realized gains of $4.2 billion in the second quarter and $6.6 billion in the first six months and in 2024 include after-tax realized gains on sales

of investments of $47.0 billion in the second quarter and $58.2 billion in the first six months.

The amount of investment 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.

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.
