Report of Independent registered public accounting firm

To the Administrative Committee, Plan Administrator and Plan Participants of

Acme Brick Company 401(k) Retirement & Savings Plan:

Opinion on the Financial Statements

We have audited the accompanying statement of net assets available for benefits of Acme Brick Company 401(k) Retirement & Savings Plan (the "Plan") as of December 31, 2025, and the related statement of changes in net assets available for benefits for the year ended December 31, 2025, and the related notes and schedules (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, 2025, and the changes in net assets available for benefits for the year ended December 31, 2025, in conformity with accounting principles generally accepted in the United States of America.

Other Matter

The financial statements of Acme Brick Company 401(k) Retirement & Savings Plan as December 31, 2024 and for the year ended December 31, 2024 were audited by Freed Maxick, P.C. On August 1, 2025, Freed Maxick, P.C. joined with WithumSmith+Brown, PC. Freed Maxick, P.C. expressed an unqualified opinion on those financial statements dated June 20, 2025.

Basis for Opinion

These financial statements are the responsibility of the Plan's management. Our responsibility is to express an opinion on these financial statements based on our audit. 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 audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. As part of our audit, we are required to obtain an understanding of internal control over financial reporting, but not for the purposes of expressing an opinion on the effectiveness of the Plan's internal control over financial reporting. Accordingly, we express no such opinion.

Our audit 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 audit 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 audit provides a reasonable basis for our opinion.

Supplemental Information

The supplemental information in the accompanying schedule of Schedule H, Line 4i - Schedule of Assets (Held at End of Year) as of December 31, 2025 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.

ACME BRICK COMPANY 401(k) RETIREMENT & SAVINGS PLAN

Notes to Financial Statements

Year Ended December 31, 2025

1.
DESCRIPTION OF PLAN

The following description of the Acme Brick Company (the "Company") 401(k) Retirement & Savings Plan (the "Plan") provides only general information. The Company is an indirect subsidiary of Berkshire Hathaway, Inc. ("Berkshire"). Participants should refer to the Plan document for a more complete description of the Plan's provisions.

a.
General. The Plan is a defined contribution plan which covers all employees. Employees are eligible to participate in the Plan as of the first day of the month on or after each employee has completed sixty (60) days of service and reached the age of eighteen (18). Employees hired on or after July 1, 2019 are automatically enrolled in the Plan at a deferral rate of 3% after the two aforementioned criteria are met and after a 30-day grace period to opt out. The Plan is subject to the provisions of the Employee Retirement Income Security Act of 1974 ("ERISA"). The Company's Board of Directors is responsible for oversight of the Plan. The Administrative Committee determines the appropriateness of the Plan's investment offerings, monitors investment performance and reports to the Company's Board of Directors.
b.
Contributions. Employees may make voluntary pre-tax contributions or after-tax Roth 401(k) contributions through salary deferrals, limited to 65% of each employee's eligible earnings, but not more than the maximum allowed by law. Contributions for employees hired on or after July 1, 2019 automatically increase 1% each year, up to a maximum of 5%, on the employee's enrollment anniversary. Employee contributions are subject to Internal Revenue Code (the "Code") limitations. The maximum contribution allowed by the Plan was $23,500 in 2025. Employees who are 50 or older as of December 31, 2025 and reach either the maximum before-tax contribution limit of 65% or maximum contribution allowed by the Plan may make catch-up contributions. The catch-up contribution limit was $7,500 for 2025, or $11,250 for participants aged 60 to 63, and is eligible for Company matching.

For the year ended December 31, 2025, Company matching contributions were equal to 50% of the sum of each employee's voluntary pre-tax contributions and after-tax Roth contributions up to five percent of the employee's eligible earnings. The Company's Board of Directors determines the matching percentage. Company matching contributions totaled $1,847,070 for the year ended December 31, 2025. Forfeiture balances of $225,000 will be applied against the 4th quarter amount due of $536,854 in 2026.

Any employee of the Company may roll over distributions made from a previous employer's qualified retirement plan into the Plan.

c.
Participant accounts. Each participant's account is credited with the employee's contributions and an allocation of the Company's contributions and investment earnings. Allocations are based on participants' 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.
d.
Vesting. Participants have a fully vested, nonforfeitable right to employee contributions. Company matching contributions are allocated to all participants and become fully vested after participants have completed three years of vested service. A participant's account balance shall be 100% vested upon normal retirement (age 65), disability or death. Effective January 1, 2020, Company matching contributions are fully vested for any participant whose separation from service is the result of a reduction in force. One year of vested service is credited for each calendar year in which a participant has at least 1,000 hours of service. Forfeitures of the Company match may be used to pay Plan expenses or fund other matching contributions; however, the forfeiture amount is credited back to participants upon re-employment with the Company. Forfeiture balances as of December 31, 2025 and 2024 were approximately $235,000 and $236,000, respectively.
e.
Payment of benefits. Withdrawals of vested contributions from the Plan by participants can be made at normal retirement (age 65), when a participant dies, becomes disabled or a break in service occurs. There is no plan provision for early retirement. Distributions upon withdrawal are made in accordance with the Plan document.
f.
Notes receivable from participants. Participants are allowed to apply for and receive loans from their vested account balance, subject to certain requirements, including the provision that they may not have more than one outstanding loan at a time. The minimum loan amount is $1,000 and the maximum is 50% of the participant's vested balance, but never more than $50,000 minus the highest outstanding balance of the participant's total Plan loans during the last 12 months. The loans are secured by the balance in the participant's account. A reasonable rate of interest is charged on loans. Currently, the Plan charges interest at the federal Prime rate plus 2%.
2.
SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
a.
Basis of accounting. The financial statements of the Plan are prepared under the accrual method of accounting in accordance with accounting principles generally accepted in the United States of America ("GAAP").

6

b.
Estimates. The preparation of financial statements in accordance with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.
c.
Investments. Investments are reported at fair value. Fair value is 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 Plan's Investment Committee determines the Plan's valuation policies utilizing information provided by the investment advisers, custodians and insurance company. See note 3 for discussion of fair value measurements.

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. Realized gains and losses for security transactions are recorded using the average cost method.

d.
Notes receivable from participants. Participant loans are valued at unpaid principal balance plus accrued interest. Related fees are recorded as administrative expenses and are expensed when they are incurred.
e.
Contributions. Contributions by participants and participating employers are accounted for on the accrual basis once determined.
f.
Benefit payments. Benefit payments are recorded when paid.
3.
FAIR VALUE MEASUREMENTS

The framework for measuring fair value provides a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1) and the lowest priority to unobservable inputs (Level 3). The three levels of the fair value hierarchy under Financial Accounting Standards Board Accounting Standards Codification Topic No. 820, Fair Value Measurement, 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 include:
quoted prices for similar assets or liabilities in active markets;
quoted prices for identical or similar assets or liabilities in inactive markets;
inputs other than quoted prices that are observable for the asset or liability;
inputs that are derived principally from or corroborated by observable market data by correlation or other means.
Level 3 - inputs to the valuation methodology are unobservable and significant to the fair value measurement.

The asset 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 maximize the use of relevant 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 and 2024. These methodologies were consistently applied to all investments of the Plan.

Cash and cash equivalents (money market funds)

Demand deposit funds are carried at amortized cost which approximates fair value. The investments are classified within Level 2 of the valuation hierarchy.

Common stock

Common stock is valued at the closing price reported on the active market on which the individual securities are traded. All common stock is classified within Level 1 of the valuation hierarchy.

Common/collective trust funds

The common/collective trust funds ("CCT") are valued using Net Asset Value ("NAV") per share as a practical expedient. NAV is based on the fair value of the underlying investments held by the fund less its liabilities. In accordance with GAAP, since each CCT is measured using the NAV per share practical expedient, the CCT's are not classified in the fair value hierarchy. The fair value amounts for the CCT's presented in the table below are intended to permit reconciliation to the amounts presented in the Statements of Net Assets Available for Benefits.

7

Collective investment trusts

The collective investment trusts ("CIT") are tax-exempt, pooled investment vehicles that are valued daily by the CIT manager. CIT funds are not regulated by the Securities and Exchange Commission ("SEC"). They are regulated through the Office of the Comptroller of the Currency. CIT's are not publicly traded, however the daily price of the funds are publicly available through the Nasdaq Fund Network. All CITs are classified within Level 2 of the valuation hierarchy.

Mutual funds

Mutual funds are valued at the daily closing price as reported by the fund. Mutual funds held by the Plan are open-end mutual funds that are registered with the SEC. These funds are required to publish their daily NAV and to transact at that price. The mutual funds held by the Plan are deemed to be actively traded. All mutual funds are classified within Level 1 of the valuation hierarchy.

The following table sets forth by level, within the fair value hierarchy, the Plan's investments at fair value as of December 31, 2025 and 2024. The Plan has no assets classified within Level 3 of the valuation hierarchy. Additionally, there were no transfers in or out of Level 3 investments during 2025 or 2024.

4.
TAX STATUS OF PLAN

Effective July 15, 2022, the Plan sponsor adopted a prototype plan sponsored by Bank of America Merrill Lynch. The prototype plan received an opinion letter dated June 30, 2020 in which the Internal Revenue Service ("IRS") stated that the prototype plan was in compliance with the applicable requirements of the Code. In addition, the opinion letter stated that an employer who adopts this prototype plan may rely on the prototype plan opinion letter with respect to the qualification of its plan under the Code. Therefore, the Plan's Administrative Committee believes that the Plan is being operated in compliance with the applicable provisions of the Code.

GAAP requires plan management to evaluate tax positions taken by the plan and recognize a tax liability if the plan has taken an uncertain position that more likely than not would not be sustained upon examination by the IRS. The Plan is subject to routine audits by taxing jurisdictions; however, there are currently no audits for any tax periods in progress.

5.
EXCESS CONTRIBUTIONS PAYABLE

Amounts payable to participants for contributions in excess of amounts allowed by the IRS are recorded as a liability with a corresponding reduction to contributions. The Plan distributed the 2025 excess contributions to applicable participants prior to March 15, 2026. The Plan distributed the 2024 excess contributions to applicable participants prior to March 15, 2025.

6.
ADMINISTRATIVE EXPENSES

Certain expenses of maintaining the Plan are paid by the Plan, unless otherwise paid by the Company. Expenses that are paid by the Company are excluded from these financial statements. 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 related expenses are included in net appreciation of fair value of investments.

7.
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. Upon termination, all participants would become 100% vested in their employer contributions and Plan assets would be distributed accordingly.

8.
RELATED PARTIES AND PARTIES-IN-INTEREST

The Plan holds investments in the common stock of Berkshire, which qualifies as a party-in-interest transaction. At December 31, 2025 and 2024 the Plan held 46,678 shares and 51,367 shares, respectively. The net realized/unrealized depreciation in fair value of Berkshire common stock held by the Plan was $94,682 for the year ended December 31, 2025.

The Plan holds investments in the Merrill Lynch Bank Deposit Program, a cash account managed by Bank of America, N.A., which acted as trustee for only those investments as defined by the Plan, which qualifies as a party-in-interest transaction. The cash value as of December 31, 2025 totaled $764,593. No reportable cash was held as of December 31, 2024.

As of December 31, 2025 and 2024, the outstanding notes receivable from participants were $1,412,026 and $1,794,909, 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.

10.
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. 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 participants' account balances and the amounts reported in the statement of net assets available for benefits.
