The following description of The Nebraska Furniture Mart, Inc. Profit Sharing Plan (the Plan) provides only general information. Participants should refer to the Plan document for a more complete description of the Plan’s provisions.

The Plan, most recently amended September 1, 2025, is a defined contribution profit-sharing plan covering all employees, as defined in the Plan document, as of the start date of the employee. The employees covered under the Plan include those employed by Nebraska Furniture Mart, Inc., Floors, Inc., NFM of Kansas, Inc., NFM Custom Countertops LLC, TXFM, Inc., NFM of Cedar Park, Inc. and NFM Wellness, LLC (collectively the Company or Employer). The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 (ERISA).

Effective July 10, 2017, employees are auto-enrolled, upon hire, at a 4% pre-tax deferral and a 1% auto increase on their anniversary hire date. Prior to July 10, 2017 employees were auto-enrolled at a 3% pre-tax deferral. Each year, participants may contribute up to 50% of their eligible compensation, as defined by the Plan document. Contributions are subject to certain dollar limitations, as imposed by the Internal Revenue Code (IRC). Participants also may rollover amounts representing distributions from other qualified plans. Participants who have attained age 50 before the end of the Plan year are eligible to make catch-up contributions. Effective February 24, 2025 participants between the age of 60-63 are allowed to contribute a higher contribution amount to the catch-up contributions as outlined by Secure Act 2.0. Participants direct the investments of employee and Employer contributions into various investment options offered by the Plan.

Once an employee has completed one year of service, they are eligible for discretionary matching contributions (Matching Contributions) on the following paycheck after the one year anniversary has been met. In addition, the Company may make additional profit sharing contributions (Profit Sharing Contributions), subject to limitations established by the IRC. No additional Profit Sharing Contributions were made for the years ended December 31, 2025 or 2024.

Each participant’s account is credited with the participant’s contribution and allocations of (a) the Company’s contributions and (b) Plan earnings and charged with an allocation of 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.

In the event of disability, death, or normal retirement age, the participant will become fully vested.

Participants may borrow from their accounts a minimum of $1,000 up to a maximum of 50% of their vested account balance relating to participant’s contributions and rollovers under the Plan, or a maximum of $50,000. The notes are secured by the participant’s account balance in the participant’s account and bear interest rates, which are equal to the Prime Rate plus 1%. Principal and interest are paid ratably through biweekly payroll deductions over a period not to exceed five years. Effective September 1, 2016, the Plan only allows general purpose loans that do not exceed a five-year term. As of December 31, 2025, and 2024, interest rates ranged from 4.25% to 9.50% and are fixed for the life of the loan. As of December 31, 2025, notes receivable from participants mature between January 2026 and January 2031.

The following accounting policies, which conform with accounting principles generally accepted in the United States of America (U.S. GAAP) and with the requirements of ERISA, have been used consistently in the preparation of the Plan’s financial statements.

Various inputs are used to determine the fair value of the Plan’s investments. These inputs are summarized in three broad levels described below:

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 include:

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.

The asset’s or liability’s fair value measurement level within the fair value hierarchy is based on the lowest level of any 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.

Following is a description of the valuation methodologies used for investments measured at fair value. There have been no changes in the methodologies used at December 31, 2025 or 2024.

Mutual Funds: Valued at fair value as determined by quoted market prices, which represents the net asset value of shares held by the Plan at year end and classified within Level 1 of the valuation hierarchy.

Money Market Fund: Money market funds are valued based on the short-term cash component as of the measurement date and classified within Level 2 of the valuation hierarchy as they are not publicly traded.

Berkshire Hathaway Class B Common Stock Fund: The Berkshire Hathaway Class B Common Stock Fund is valued using a quoted active market price which is considered a Level 1 input.

Common Collective Trusts: Common/collective trusts are valued based on the calculated net asset value of the respective investment entity. Although the trusts themselves are not publicly traded, the underlying assets are traded on exchanges and on other markets, and price quotes for the assets held by these trusts are readily available. Additionally, the net asset value per share is determined and published daily and is the basis for current transactions. These investments are classified as Level 2 in the hierarchy.

Vanguard Retirement Savings Trust III: Vanguard Retirement Savings Trust III (“VRSTIII”) invests in fully benefit-responsive investment contracts, including traditional contracts, and wrapper contracts re-bid to determine the replacement cost and underlying bond instruments valued by the Trustee. The net asset value is used as a practical expedient to estimate fair value. The 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 net asset value. Participant redemption from the VRSTIII is permitted on any day that US securities markets are open. Trustee requires a twelve month written notice for plan level liquidation of the VRSTIII. There are no unfunded commitments.

(4) Plan Termination

Although it has not expressed any intent to do so, the Company has the right under the Plan to discontinue its contributions at any time and to terminate the Plan subject to the provisions of ERISA. In the event of Plan termination, participants would become 100% vested in their entire account.

(5) Tax Status

The Plan has adopted a prototype plan. The prototype plan has received an opinion letter from the Internal Revenue Service (IRS) dated June 30, 2020 as to the prototype plan’s qualified status. The prototype plan opinion letter has been relied upon by this Plan. The plan administrator believes the Plan is designed and is being operated in compliance with the applicable provisions of the IRC.

Once qualified, the Plan is required to operate in conformity with the Code to maintain its qualification. The Company believes that the Plan is being operated in compliance with the applicable requirements of the Code and, therefore, believes that the Plan was qualified and the related trust was tax-exempt as of the financial statement date.

U.S. GAAP requires management to evaluate tax positions taken by the Plan and recognize a tax liability (or asset) if the Plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan administrator has analyzed the tax positions taken by the Plan and has concluded that as of December 31, 2025, there are no uncertain positions taken or expected to be taken that would require recognition of a liability (or asset) or disclosure in the financial statements. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

(6) Risks and Uncertainties

The Plan invests in various marketable securities. Marketable securities are exposed to various risks, such as interest rate, market, and credit. Due to the level of risk associated with certain marketable securities and the level of uncertainty related to changes in the value of marketable securities, it is at least reasonably possible that changes in values of marketable securities in the near term would materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits and the statement of changes in net assets available for benefits.

(7) Related Parties and Party-in-Interest Transactions

The Plan invests in shares of mutual funds, a money market fund, and common collective trusts managed by an affiliate of the Trustee and, therefore, transactions in such investments, as well as loans made to participants, qualify as party-in-interest transactions, which are exempt from the prohibited transaction rules. Additionally, the Plan has a number of service providers, which qualify as parties-in-interest. Fees paid by the Plan to parties-in-interest amounted to approximately $557,000 and $579,000 for the years ended December 31, 2025 and 2024, respectively.

The Plan also invests in the Class B common stock fund of Berkshire Hathaway. The Plan had purchases of approximately $1,162,000 and $1,577,000 of Berkshire Class B Common Stock Fund during the years ended December 31, 2025 and 2024, respectively. The Plan had approximately $1,359,000 and $1,134,000 of sales of the Berkshire Class B Common Stock Fund during the years ended December 31, 2025 and 2024, respectively.
