NOTE A - DESCRIPTION OF PLAN

The following description of the Benjamin Moore & Co. Deferred Savings and Investment Plan (the “Plan”) provides only general information. The Participants should refer to the Plan document and subsequent amendments for a more complete description of the Plan’s provisions. The Plan is sponsored and administered by Benjamin Moore & Co. (the “Company”). The Company is a wholly-owned subsidiary of Berkshire Hathaway Inc. (the “Parent”). Charles Schwab Bank (“Schwab”) is the appointed trustee (“Trustee”) and Charles Schwab Corporation – Schwab Retirement Plan Services, Inc. is the recordkeeper of the Plan.

General:

The Plan is a safe-harbor plan and permits eligible employees of the Company to participate in the Plan on the first day of the month following the date of hire. Also, the Plan accepts “Roth” after tax contributions and elective deferrals on behalf of participants. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (“ERISA”). The Board of Trustees is responsible for oversight of the Plan. The Investment Committee determines the appropriateness of the Plan’s investment offerings, monitors investment performance and reports to the Plan’s Board of Trustees.

Participants may contribute amounts representing distributions from other qualified plans. The Plan also permits participants to make voluntary elective transfers of their entire account balance to or from this Plan to or from another qualified section 401(k) plan. The plan transfer must be made in connection with a participant’s change in employment status which results in the participant not being entitled to additional allocations under the prior plan.

Investments:

Participants have the option to direct the investment of participant and employer contributions into various investment options offered by the Plan.

Participant accounts:

Each participant’s account is adjusted for the participant’s contribution and allocations of (a) the Company’s contributions and (b) Plan earnings and losses, and charged with an allocation of certain administrative expenses. Allocations are based on participant earnings or account balances, as defined. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Contributions and eligibility:

All employees can voluntarily contribute up to 50 percent of annual compensation, as defined in the Plan document, up to the Internal Revenue Code (“IRC”) maximum allowance. The IRC maximum allowance was $23,500 and $23,000 in 2025 and 2024, respectively. Participants age 50 and older may contribute an additional $7,500 as a catch-up contribution in 2024 and 2023, resulting in a total pre-tax contribution limit of $31,000 and $30,500 for 2025 and 2024, respectively. Effective January 1, 2025, participants between the ages of 60 and 63 before the close of the applicable Plan Year, may contribute an additional $3,750 as a "super" catch-up, resulting in a total pre-tax contribution limit of $34,750 for 2025.

The Plan includes an auto enrollment feature whereby all newly eligible employees shall be automatically enrolled at a deferral rate of 6% within 45 days of their date of hire if they have not voluntarily enrolled prior to that date or affirmatively elected not to participate in the Plan. The Plan also has an escalation provision feature that will increase each year by 1% up to 50% of compensation, unless the participant affirmatively elects not to participate.

All employees can elect to voluntarily make after-tax contributions in an amount up to 50% of the employee’s compensation. The Company will not make any matching contributions on after-tax contributions, and are subjected to IRC maximum allowance amounts, mentioned above.

All employees are permitted to convert pre-tax funds within the Plan to a Roth 401(k) through an In-Plan Roth conversion.

Contributions are matched for 100 percent of the participant-directed contribution, up to 6% of eligible earnings. Matching contributions are funded each pay period. There is an annual 3% special discretionary contribution to be contributed by the Plan Sponsor for wage and hourly employees employed on the last day of the Plan year and on the retirement date for Retirees who retire within the Plan year. The special discretionary contributions are included in Employer contributions receivable and were $1,238,025 and $1,144,990 as of December 31, 2025 and 2024, respectively.

As stated above, the maximum limit on the amount of pre-tax salary deferrals a participant can contribute each year is defined within the IRC. If a participant reaches this limit early in the year, the participant will continue to receive the Company matching contributions; however, it is possible that the participant will not receive the maximum Company match for the year or receive an amount

NOTE B - SUMMARY OF ACCOUNTING POLICIES

NOTE C – FAIR VALUE MEASUREMENTS

Fair value is 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.

The established framework provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The three levels of the fair value hierarchy are described as follows:

Level 1 - Inputs to the valuation methodology are unadjusted quoted prices for identical assets or liabilities in active markets that the Plan has the ability to access.

Level 2 - Inputs to the valuation methodology that are observable, either directly or indirectly, such as quoted prices for similar assets or liabilities; quoted prices in markets that are not active; or other inputs that are observable or can be corroborated by observable market data for substantially the full term of the assets or liabilities. If the asset or liability has a specified (contractual) term, the Level 2 input must be observable for substantially the full term of the asset or liability.

Level 3 - Inputs to the valuation methodology are unobservable and significant to the fair value measurement.

A financial instrument’s categorization within the valuation hierarchy is based upon the lowest level of input that is significant to the fair value measurement. Valuation techniques used need to maximize the use of observable inputs and minimize the use of unobservable inputs. The following is a description of the valuation methodologies used for the Plan’s instruments measured at fair value, including the general classification of such instruments pursuant to the valuation hierarchy. There have been no changes in the methodologies used as of December 31, 2025 and 2024.

Stable Value Collective Trust Fund

A stable value fund is a form of common collective trust funds, which is composed primarily of fully benefit-responsive investment contracts and is valued at the net asset value (“NAV”) of units of the bank collective trust. The NAV is used as a practical expedient to estimate fair value. This practical expedient would not be used if it is determined to be probable that the fund will sell the investment for an amount different from the reported NAV.

Other Common Collective Trust Funds

Common collective trust funds are comprised of shares or units in commingled funds that are not publicly traded. The underlying assets in these funds are primarily publicly traded equity securities, fixed income securities, and commodity-related securities and are valued at their NAV, as a practical expedient, that is calculated by the investment manager or sponsor of the fund and have varying liquidity, redemption period notices and other restrictions. This practical expedient is not used when it is determined to be probable that the Plan will sell the investment for an amount different than the reported NAV.

Mutual Funds

The investments in mutual funds are valued utilizing a market approach wherein the Plan uses the quoted prices in the active market for identical assets. All of these investments are traded in active markets at their NAV per share and are primarily categorized as Level 1.

NOTE D - TERMINATION OF THE PLAN

The Company expects and intends to continue the Plan indefinitely but reserves the right to amend or terminate the Plan at any future date subject to the provisions of ERISA. However, no such amendment or termination shall affect the account balance of any participant as of the date such amendment or termination takes effect, as all participants are vested at all times.

NOTE E - TAX STATUS

The IRS has determined and informed the Company by letter dated August 23, 2017 that the Plan and related trust are designed in accordance with applicable sections of the Internal Revenue Code (“IRC”). The Plan has been amended since receiving the tax determination letter. The Company believes that the Plan is designed and currently being operated in compliance with the applicable requirements of the IRC. Therefore, no provision for income taxes has been provided in the Plan’s financial statements and the Company believes the Plan is qualified, and the related trust is tax-exempt.

Accounting principles generally accepted in the United States of America require the Company and Plan to evaluate tax positions taken by the Plan and recognize a related tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by a government authority. The Plan is subject to routine examinations by taxing jurisdictions; however, there are currently no examinations for any tax periods in progress.

NOTE F – RELATED PARTY AND PARTIES-IN-INTEREST TRANSACTIONS

For the year ended December 31, 2025, there were transactions involving the investment of Plan assets in investments funds maintained by Schwab, which qualify as party-in-interest transactions. As of December 31, 2025 and 2024, the total fair value of these investments were $131,855,432 and $111,634,402, respectively. Recordkeeping services and investment related expenses for the year ended December 31, 2025 were $119,595.

The Plan has investments in its Parent’s common stock, which is accumulated in an investment account labeled the Berkshire Hathaway Stock Fund, which qualifies as a party-in-interest transaction and also has a cash component for liquidity purposes. At December 31, 2025 and 2024 the Berkshire Hathaway Stock Fund held 80,989 and 90,370 shares, respectively, of Berkshire Hathaway Class B Common Stock. The net realized/unrealized appreciation in fair value of Parent common stock held by the Berkshire Hathaway Stock Fund was $4,553,459 for the year ended December 31, 2025.

As of December 31, 2025 and 2024, the outstanding notes receivable from Plan participants were $6,008,222 and $5,130,303, respectively. Participants are a party-in-interest to the Plan and these loans were exempt party-in-interest transactions pursuant to Section 408(b)(1) of ERISA.

NOTE G – RISKS AND UNCERTAINTIES

The Plan invests in various investment securities. Investment securities are exposed to various risks, such as interest rate, market and credit risks. Market risks include global events which could impact the value of investment securities, such as a pandemic or international conflict. Due to the level of risk associated with certain investment securities, it is at least reasonably possible that changes in the values of investment securities will occur in the near term, and that such changes could materially affect the participants’ account balances and the amounts reported in the statements of net assets available for benefits.
