Report of Independent Registered Public Accounting Firm

To the Retirement Plan Committee and Plan Participants of the

Clayton Homes, Inc. 401(k) Retirement Plan

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of the Clayton Homes, Inc. 401(k) Retirement Plan (the “Plan”) as of December 31, 2024 and 2023, the related statement of changes in net assets available for benefits for the year ended December 31, 2024, and the related notes (collectively referred to as the financial statements). In our opinion, the financial statements present fairly, in all material respects, the net assets available for benefits of the Plan as of December 31, 2024 and 2023, and the changes in net assets available for benefits for the year ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

These financial statements are the responsibility of the Plan’s management. Our responsibility is to express an opinion on the Plan’s financial statements based on our audits. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (PCAOB) and are required to be independent with respect to the Plan in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. The Plan is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting, but not for the purpose of expressing an opinion on the effectiveness of the Plan’s internal control over financial reporting. Accordingly, we express no such opinion.

Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying schedule of assets (held at end of year) as of December 31, 2024, has been subjected to audit procedures performed in conjunction with the audit of the Plan’s financial statements. The supplemental information is the responsibility of the Plan’s management. Our audit procedures included determining whether the supplemental information reconciles to the financial statements or the underlying accounting and other records, as applicable, and performing procedures to test the completeness and accuracy of the information presented in the supplemental information. In forming our opinion on the supplemental information, we evaluated whether the supplemental information, including its form and content, is presented in conformity with the Department of Labor’s Rules and Regulations for Reporting and Disclosure under the Employee Retirement Income Security Act of 1974. In our opinion, the supplemental information is fairly stated, in all material respects, in relation to the financial statements as a whole.

CLAYTON HOMES, INC. 401(K) RETIREMENT PLAN

NOTES TO FINANCIAL STATEMENTS

December 31, 2024 and 2023

NOTE 1 - DESCRIPTION OF PLAN

The following description of the Clayton Homes, Inc. 401(k) Retirement Plan (the “Plan”) provides only general information. Participants should refer to the Plan agreement for a more complete description of the Plan’s provisions.

General: The Plan is a defined contribution plan covering substantially all employees of Clayton Homes, Inc. and its subsidiaries (collectively the “Company” or the “Employer”) who have reached the age of eighteen years and provided 90 days of service. Employees may enter the Plan immediately following eligibility. Employees who have reached the age of eighteen years and provided one year of service are eligible to receive the Company matching contributions at the beginning of the quarter following one year of service. The Plan is subject to the Employee Retirement Income Security Act of 1974 (ERISA).

Contributions: Participants may voluntarily make qualified retirement contributions to the Plan which are deductible by the participants for federal income tax purposes under Section 401(k) of the Internal Revenue Code (“IRC”) or may be made after-tax in the form of a Roth 401(k) contribution. If a participant elects to contribute to the Plan, they may contribute from 1% up to 75% of their eligible wages. Participants who fail to make an affirmative election are automatically enrolled at a 4% deferral rate upon becoming eligible to participate in the Plan, increasing by 1% each year, up to 11%, and they may elect to change or discontinue deferrals at any time. Participant after-tax contributions are limited to 18% of the participant’s eligible compensation. Participants may elect to contribute up to a maximum of $23,000 and $22,500 per participant for 2024 and 2023, respectively, plus an additional $7,500 for participants age 50 or older for both 2024 and 2023. The maximum contribution amount is adjusted annually for inflation, as announced by the United States Secretary of the Treasury. Participants’ contributions to the Plan are made by means of payroll deductions during each regular payroll period. Participants direct investments of their contributions into various investment options offered by the Plan.

The Company provided a Safe Harbor match consisting of a 4% match during 2024 and 2023. Under a Safe Harbor Plan, Safe Harbor 401(k) matching contributions are immediately 100% vested.

Rollover contributions from other qualified plans and individual retirement accounts are allowed by the Plan.

Participant Accounts: During the Plan year, participants’ accounts are increased by the participants’ elective deferrals, the Employer’s contributions, and their respective proportionate shares of any investment earnings and increases in the fair value of the funds during the year. Participants’ accounts are reduced by any payments made from such accounts and their respective proportionate shares of any decreases in the fair market value of the funds. Allocations are based on participants’ earnings or account balances, as defined by the Plan document. The benefit to which participants are entitled is the benefit that can be provided from the participants’ vested accounts.

Vesting: Participants are 100% vested in their voluntary contribution account and their Safe Harbor employer contribution account.

Payment of Benefits: Benefit distributions equal to participants’ vested account balances are payable to participants or their beneficiaries upon the earlier of retirement (age 59 1/2) or upon their death, disability or termination of employment. The method of distribution shall be determined by the Plan Administrator in accordance with the provisions of the Plan.

Administrative and Investment Management Expenses: Certain expenses of maintaining the Plan are paid directly by the Company and are excluded from these financial statements. Plan recordkeeping and trustee fees are paid by the Plan and are reflected in the financial statements as administrative expenses. Fees related to the administration of notes receivable from participants are charged directly to the participant’s account and are included in administrative expenses. Investment management fees are charged to the Plan as a reduction of investment return and included in the investment income reported by the Plan.

December 31, 2024 and 2023

NOTE 1 - DESCRIPTION OF PLAN (Continued)

Notes Receivable from Participants: Participants may borrow from their accounts a minimum of $1,000 up to a maximum of $50,000 or 50% of their account balance, whichever is less. The notes are secured by the balance in the participant’s account and bear interest at fixed rates that are commensurate with local prevailing rates as determined quarterly by the Plan Administrator. Principal and interest are paid through payroll deductions.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting: The financial statements of the Plan are prepared on the accrual basis of accounting in conformity with accounting principles generally accepted in the United States of America.

Use of Estimates: The preparation of financial statements in conformity with accounting principles generally accepted in the United States of America requires the Plan Administrator to make estimates and assumptions that affect certain reported amounts and disclosures. Accordingly, actual results may differ from those estimates.

Risks and Uncertainties: The Plan holds various investment securities. Investment securities are exposed to various risks such as interest rate, market, liquidity, and credit risks. Due to the level of risk associated with certain investment securities and the sensitivity of certain fair value estimates to changes in valuation assumptions, it is at least reasonably possible that changes in the fair values of investment securities will occur in the near term and that such changes could materially affect participants’ account balances and the amounts reported in the statements of net assets available for benefits.

Investment Valuation and Income Recognition: The Plan’s investments are reported at fair value. Fair value is the price that would be received by the Plan for an asset or paid by the Plan to transfer a liability (an exit price) in an orderly transaction between market participants on the measurement date in the Plan’s principal or most advantageous market for the asset or liability.

Purchases and sales of securities are recorded on a trade-date basis. Interest income is recorded on the accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation includes the Plan’s gains and losses on investments bought and sold as well as held during the year.

Fair value measurements are determined by maximizing the use of observable inputs and minimizing the use of unobservable inputs. The hierarchy places the highest priority on unadjusted quoted market prices in active markets for identical assets or liabilities (Level 1 measurements) and gives the lowest priority to unobservable inputs (Level 3 measurements). The three levels of inputs within the fair value hierarchy are defined as follows:

Level 1: Quoted prices (unadjusted) for identical assets or liabilities in active markets that the Plan has the ability to access as of the measurement date.

Level 2: Significant other observable inputs other than Level 1 prices 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.

Level 3: Significant unobservable inputs that reflect the Plan’s own assumptions about the assumptions that market participants would use in pricing an asset or liability.

In some cases, a valuation technique used to measure fair value may include inputs from multiple levels of the fair value hierarchy. The lowest level of significant input determines the placement of the entire fair value measurement in the hierarchy.

NOTE 2 - SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (Continued)

The following presents the valuation methods and assumptions used by the Plan to estimate the fair values of investments.

Mutual funds, money market funds, and common stock: The fair values of mutual fund, money market fund, and common stock investments are determined by obtaining quoted prices on nationally recognized securities exchanges (Level 1 inputs).

Stable value collective trust fund: The fair values of participation units in the stable value collective trust are based upon the net asset values per unit as reported by the fund manager. The fund invests 100% in Galliard Stable Return Fund E. The Fund seeks safety of principal and consistency of returns while attempting to maintain minimal volatility. The Fund is designed for investors seeking more income than money market funds without the price fluctuation of stock or bond funds. Galliard Stable Return Fund E primarily invests in investment contracts, including traditional guaranteed investment contracts (GICs) and security-backed contracts issued by insurance companies and other financial institutions. Units of the fund are issued and redeemed at the latest net asset value which is determined daily. There are no advance notification requirements for this fund.

Commingled pool collective trust funds: The fair values of participation units in the commingled pool collective trusts are based upon the net asset values per unit as reported by the fund managers. The funds invest in various growth funds. The funds’ objectives are to provide capital appreciation through the active management of equities across a variety of markets. Units of the funds are issued and redeemed at the latest net asset value which is determined daily. There are no advance notification requirements for these funds.

Investments measured at fair value on a recurring basis are summarized below:

* Investments measured at fair value using net asset value per share (or its equivalent) have not been classified in the fair value hierarchy as a practical expedient under Accounting Standard Codification (ASC) 820. The fair value amounts presented in the hierarchy tables for such investments are intended to permit reconciliation of the fair value hierarchy to the investments at fair value line item presented in the statements of net assets available for benefits.

Notes Receivable from Participants: Notes receivable from participants are reported at their unpaid principal balance plus any accrued but unpaid interest, with no allowance for credit losses, as repayments of principal and interest are received through payroll deductions and the notes are collateralized by the participants’ account balances. Notes receivable from participants are $54,193,299 and $43,380,105 as of December 31, 2024 and 2023, respectively.

Payment of Benefits: Benefits are recorded when paid.

Events Occurring After Reporting Date: Plan management has evaluated events and transactions that occurred between December 31, 2024 and the issuance of the report for possible recognition or disclosure in the financial statements.

NOTE 3 – TAX STATUS OF PLAN

The Plan obtained a favorable determination letter on February 13, 2017, in which the Internal Revenue Service (“IRS”) state that the Plan was in compliance with the applicable requirement of the IRC. The Plan is required to operate in conformity with the IRC to maintain its qualification. The Plan has been amended since receiving the determination letter. However, the Plan Administrator believes that the Plan is designed and is currently being operated in compliance with the applicable provisions of the IRC.

Accounting principles generally accepted in the United States of America require plan 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.

NOTE 3 – TAX STATUS OF PLAN (Continued)

The Plan Administrator has analyzed the tax positions taken by the Plan, and has concluded that as of December 31, 2024 and 2023, 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.

NOTE 4 – PLAN TERMINATION

Although it has not expressed any intention to do so, the Company has the right to discontinue contributions at any time and to terminate the Plan subject to the related provisions of ERISA.

NOTE 5 – PARTY-IN-INTEREST TRANSACTIONS

Parties-in-interest are defined under Department of Labor regulations as any fiduciary of the Plan, any party rendering service to the Plan, the employer, and certain others. The Plan holds certain mutual funds and collective trusts managed by Fidelity Investments which qualify as party-in-interest investments. The Plan also holds notes receivable from participants that qualify as party-in-interest transactions. The Plan’s payments of administrative fees to Fidelity Investments of $1,277,185 in 2024 and payments of $542,376 in investment management fees in 2024 also qualify as party-in-interest transactions.

The Plan also holds 166,741 shares and 167,495 shares at December 31, 2024 and 2023, respectively, of Berkshire Hathaway Class B Common Stock valued at $75,580,484 and $59,738,897 at December 31, 2024 and 2023, respectively. Net realized gains related to these shares of $2,927,989 at December 31, 2024 qualify as party-in-interest transactions. Berkshire Hathaway Inc. owns 100% of the Company.
