Wickliffe, Ohio

Opinion on the Financial Statements

We have audited the accompanying statements of net assets available for benefits of The Lubrizol Corporation Employees’ Profit Sharing and Savings Plan (the “Plan”) as of December 31, 2023 and 2022, and the related statements of changes in net assets available for benefits for the years then ended, and the related notes and schedule (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, 2023 and 2022, and the changes in net assets available for benefits for the years then ended, 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 audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud.

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 schedule of assets (held at end of year) as of December 31, 2023 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.

PROFIT SHARING AND SAVINGS PLAN

NOTES TO FINANCIAL STATEMENTS

YEARS ENDED DECEMBER 31, 2023 AND 2022

1. DESCRIPTION OF THE PLAN

The following brief description of The Lubrizol Corporation Employees’ Profit Sharing and Savings Plan (the “Plan”) is provided for general information purposes only. Participants should refer to the Plan document for more complete information.

General—The Lubrizol Corporation (the “Company”) established the Plan for the purpose of encouraging employee long-term, tax-deferred savings for retirement. The Plan is subject to the reporting and disclosure requirements, the vesting standards and the fiduciary responsibility requirements of the Employee Retirement Income Security Act of 1974, as amended (“ERISA”).

All investments of the Plan are held by Empower Trust Company, LLC (“Trustee”) in participant-directed investment funds and the Plan’s recordkeeper is Empower Retirement, LLC (“Empower”).

Administration—The Plan is administered by the Employee Benefits Administrative Committee (the “Committee”), which is appointed by the Chief Executive Officer of the Company. The Committee’s powers and duties relate to the issuance of interpretive rules and regulations in accordance with the Plan document, including determination of the method and timing of benefit distributions and authorization of disbursements from the Plan, as well as the selection of the recordkeeper.

The Retirement and Savings Plans Investment Committee, which is also appointed by the Chief Executive Officer of the Company, reviews and approves investment and funding strategies, objectives and policies, and makes any necessary or desirable changes; reviews, selects and monitors the performance of investment options for participants in the Plan; and appoints and removes investment managers, trustees, consultants and other service providers (other than the recordkeeper) and monitors the performance, fees and expenses of each. The Plan document and trust agreement provide that the Trustee of the Plan shall hold, invest, reinvest, manage, and administer all assets of the Plan as a trust fund for the exclusive benefit of participants and their beneficiaries.

Participation and Contributions—All regular employees of the Company and of participating subsidiaries and affiliates are eligible for participation on the first day of covered employment.

The combined before-tax (“CODA”), after-tax Roth 401(k) (“Roth”) and after-tax (“Supplemental”) contributions are limited to 75% of eligible compensation for both highly and non-highly compensated employees. Company Matching contributions equal 100% of an employee’s combined CODA, Roth and Supplemental contributions up to 6% of the employee’s eligible compensation. This matching contribution is intended to enable the Plan to meet the rules of a 401(k) safe harbor plan. The maximum eligible compensation set by the Internal Revenue Service for purposes of allocating Plan contributions was $330,000 and $305,000 for 2023 and 2022, respectively.

CODA and Company Matching contributions are excluded from the participants’ taxable income until such amounts are received by them as a distribution from the Plan. Roth and Supplemental contributions are made on an after-tax basis and are therefore included in the participants’ taxable income in the period of contribution. Participants who turned at least age 50 during 2023 or 2022 were eligible to elect to make an additional before-tax or Roth Catch-up contribution of up to $7,500 and $6,500 in 2023 and 2022, respectively, if they met one of the following conditions:

a. Elected to make before-tax and Roth 401(k) contributions of 75% of eligible compensation; or

b. Contributed $22,500 or $20,500 for the 2023 or 2022 plan years, respectively.

Newly eligible employees, both new hires and rehires, are subject to automatic enrollment. Participants will be automatically enrolled in the Plan at a CODA contribution rate of 6%. Prior to January 1, 2023, newly eligible employees were automatically enrolled in the Plan at a CODA contribution rate of 3%.

There is a 30-day opt-out period during which participants may change their CODA contribution rate or elect not to contribute (“opt-out”). If participants do not make a positive election or opt-out, contributions will begin to be withheld as soon as administratively possible following the end of the 30-day period. CODA contributions and Company Matching contributions will be invested in the applicable State Street Target Retirement Fund that most closely matches a retirement age of 65. Once enrolled, participants may choose to change the election percentage, reallocate investments or stop contributing at any time.

4

For participants who become participants on or before January 1 of the current year with plan contribution rates between 0% and 9% of pay (whether those contributions are CODA, Roth, Supplemental, or any combination) as of July 1 of the current year, such participants will automatically have their CODA contribution rate increase to the next higher full percent starting the first full pay period after July 1 of the current year (or as soon thereafter as administratively practicable). Automatic escalation will continue each year until participants are contributing 10%.

For participants who become participants after January 1 of any year, automatic escalation will work as described above, except that the first automatic escalation will not occur until July 1 of the year following the year a participant was hired.

Any additional contributions made to a participant’s Plan account as a result of auto escalation will be invested in the Plan’s core investment funds in accordance with the participant’s election on file. If a participant does not have an election on file, those amounts will be invested in the applicable State Street Target Date Retirement Fund that most closely matches a retirement age of 65.

Participants have the right to opt-out of their scheduled auto escalation before it would otherwise take effect. The opt-out election affects only the 12-month period for which the election is made. If the participant does not want to be automatically escalated on the following July 1, the participant will need to opt-out again.

The Company contributes an annual amount (“Age-Weighted Contribution”) to the Plan for certain employees. The Age-Weighted Contribution is determined according to the rules contained in the Plan document and is allocated to each participant’s account based upon the year-end compensation and age of the employee, as defined in the Plan document.

The following table shows the percentage of compensation the Company will contribute to a participant’s account.

Participant’s age on last day of Plan Year	Contribution percentage (*)
Under Age 36	3.00%
36 – 40	3.75%
41 – 45	4.50%
46 – 50	5.25%
51 – 55	6.00%
56 – 60	6.75%
Age 61 and Older	7.50%

* Except that the contribution percentage for a Plan Year for a participant who is an employee of Chemtool Incorporated as of the last day of the Plan Year is 1.00%, regardless of the participant’s age on the last day of the Plan Year.

The Company may also contribute a portion of its adjusted consolidated net income, as defined in the Plan document, to the Plan (“Profit Sharing”). The Profit Sharing contributions are determined by the Organization and Compensation Committee of the Company and are allocated to each participant’s profit sharing account based upon the year-end compensation of the employee, as defined in the Plan document. Future Profit Sharing contributions are not anticipated at this time.

In addition to the above contributions, the Plan provides for rollover contributions (described in Sections 402, 403 and 408 of the Internal Revenue Code) and transferred contributions from certain other tax-qualified plans by or on behalf of an employee in accordance with procedures established by the Company. The Plan does not accept Roth rollover contributions.

Participant Accounts—Each participant’s account is credited with the participant’s contributions, allocations of the Company Matching, Age-Weighted, and Profit Sharing contributions, income from investments, gains or losses on sales of investments, appreciation or depreciation in the market value of investments and expenses, if any. The benefit to which a participant is entitled is the benefit that can be provided from the participant’s vested account.

Investment of Contributions—Participants elect investment of their CODA, Roth and Supplemental contributions in one or more of the Plan’s investment funds in 1% increments. All participants, regardless of age or vested ownership percentage, are able to direct the investment of the Company Matching and Age-Weighted contributions made to their account into any of the Plan’s investment funds. Participants may elect to change their investment elections as to future contributions and may also elect to reallocate once daily a portion or all of past CODA, Roth, Supplemental, Company Matching, Catch-up, Roth Catch-up, Age-Weighted, and Profit Sharing contributions among the available investment funds in increments of 1% of the total amount to be reallocated or through the transfer of specified amounts. Participants may elect investment of their CODA, Roth and Supplemental contributions, up to 50% of their vested account balance, in one or more mutual funds through a self-directed brokerage account.

5

If an employee does not make an investment election, any CODA, Roth, Supplemental, Company Matching, Catch-up, Roth Catch-up, Age-Weighted, and Profit Sharing contributions will be deposited in the applicable State Street Target Retirement Fund, based on the date of the employee’s hire or rehire, with the date that most closely matches a retirement age of 65, which meets the Department of Labor’s definition as a “qualified default investment alternative.”

Vesting and Distributions—Participants are immediately vested in employee and certain Company contributions.

Active participants vest in the Age-Weighted Contribution at a rate of 34% after one year of eligible service, 67% after two years of eligible service and 100% after three years. Participants also will become 100% vested if their participation in the Plan ends due to retirement on or after age 55, total and permanent disability, or death.

Participants may request voluntary withdrawals of their Supplemental contributions and may also apply for hardship withdrawals from their CODA, Roth, Catch-up and Roth Catch-up contributions, subject to adherence to Internal Revenue Service regulations as determined by the Plan’s recordkeeper, or request an in-service distribution upon attainment of age 59¹⁄₂. Active participants may request an in-service distribution of Company Matching contributions attributable to periods prior to January 1, 2015 at age 55, and Company Matching contributions attributable to periods on and after January 1, 2015 at age 59¹⁄₂.

Participants may request an in-service distribution of their Age-Weighted Contributions upon attainment of age 59-1/2. Upon attainment of age 55, vested active participants may request an in-service distribution. If a distribution is made prior to age 59-1/2, it can be in the form of monthly, quarterly or annual installments over a fixed period of time not to exceed the lifetime of the participant or as a lump-sum distribution. These installments may be adjusted in the year a participant reaches age 59-1/2 or becomes disabled. Hardship withdrawals of Age-Weighted Contributions are not allowed under the Plan.

When a participant’s employment terminates, the participant’s vested account balances may be distributed in a single lump sum. Participants may also elect installment distribution payments or partial withdrawals of their vested account balance. Amounts distributed from the Berkshire Hathaway Class B Stock Fund are paid in the form of Class B shares of Berkshire Hathaway or their cash equivalent at the participant’s election.

The Plan provides for the automatic distribution of Plan balances of a separated participant (or a participant’s beneficiary, in the event of the Participant’s death) of $5,000 or less, and, if the Participant does not otherwise elect to receive such distribution as a payment or as direct rollover to another plan, to provide for the rollover of such balance to an individual retirement account established for the Participant.

Notes Receivable From Participants—The Plan allows participants to borrow up to the lesser of $50,000, 100% of the value of their CODA, Roth, Catch-up, vested Matching and Rollover accounts, or 50% of their vested total account balance. Each participant is restricted to two outstanding loans at a time, and the minimum loan is $1,000.

Participant loans accrue interest at a rate fixed at the time of the borrowings. Loan repayments are made through payroll deductions and are credited to the participant’s account. The repayment period may not be more than five years except for loans issued to purchase a principal residence, which may be repaid within fifteen years.

Forfeited Accounts—Forfeited nonvested accounts may be used to reduce future Company contributions or offset plan expenses.

In 2023 and 2022, the forfeiture balance at year end totaled $190,349 and $204,844, respectively. Subsequent to year end 2023 and 2022, $204,311 and $250,664 of the current forfeiture balance, respectively, was used to reduce Company contributions and is netted with the respective year’s contribution receivable balance.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Accounting—Each fund of the Plan is accounted for separately. The accounts of these funds are maintained, and the accompanying financial statements have been prepared, on the accrual basis of accounting.

Investments held by a defined contribution plan are required to be reported at fair value, except for fully benefit-responsive investment contracts. Contract value is the relevant measure for the portion of the net assets available for benefits of a defined contribution plan attributable to fully benefit-responsive investment contracts because contract value is the amount participants normally would receive if they were to initiate permitted transactions under the terms of the Plan.

6

Use of Estimates—The preparation of financial statements in conformity 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, liabilities and changes therein, and disclosure of contingent assets and liabilities. Actual results could differ from those estimates.

Valuation of Investments—Investments are reported at fair value other than the guaranteed investment contracts (“GICs”) included in the Stable Value Fund. GICs are stated at contract value, which is equivalent to cost plus reinvested interest. Purchases and sales of securities are recorded on a trade-date basis. Interest income is generally recorded on an accrual basis. Dividends are recorded on the ex-dividend date. Net appreciation (depreciation) in fair value of investments includes gains and losses on investments bought and sold, as well as held, during the year.

The value of all funds and the interests of participants under each fund are calculated on a daily basis based on the best information available, which may include estimated values. See Note 5 for discussion of fair value measurements.

Notes Receivable From Participants—Notes receivable from participants are measured at their unpaid principal balance plus any accrued but unpaid interest.

Expenses—Other than as described below, no fees are charged to participants for Plan administrative and operating expenses. Plan administrative and operating expenses are either paid directly by the Company or through revenue sharing by the Plan’s investment funds. The Company monitors the payments received by the Plan service providers to ensure that they are used properly for qualifying plan administrative and operating expenses. The Company reserves the right to initiate charges to participants for Plan administrative and operating costs in the future.

A participant’s account is charged a fee of $75.00 for each loan taken by the participant. If expedited mailing of a loan or distribution check is requested, an additional fee is charged to the participant’s account.

A participant who invests in the self-directed brokerage account is charged a $50.00 annual fee which is deducted quarterly ($12.50 per quarter) from the participant’s account. In addition, any mutual fund investment purchased or sold through the self-directed brokerage account may carry with it additional fees. The Empower Brokerage Fee Schedule provided to participants details such fees including a redemption fee of $50.00 for almost any mutual fund investment that is not held for at least 30 days.

A QDRO fee of $300.00 applies when the Plan is presented with a qualified domestic relations order for review and processing, and is deducted in equal portions from the accounts of the participant and the alternate payee.

Other fees primarily represent investment management advisory fees that are charged to individual participants who select this fee-based service. Fees for the aforementioned services are paid to Advised Assets Group, LLC.

Payment of Benefits—Payments are recorded when paid.

Participants may invest up to 50% of their total vested Plan account balance through the self-directed brokerage account.

The Plan has an investment contract with Goldman Sachs Asset Management through which both traditional and synthetic GICs can be held in the Plan’s Stable Value Fund. Traditional GICs are unsecured, general account obligations of insurance companies. The obligation is backed by the general account assets of the insurance company that writes the investment contract. The crediting rate on this product is typically fixed for the life of the investment. A separate account GIC is similar to a traditional GIC except investments are segregated in separate accounts maintained by an insurance company for the benefit of the investors. The total return of the segregated account assets supports the separate account GIC’s return. The crediting rate on this product will reset periodically but will not have an interest rate of less than 0%.

General fixed maturity synthetic GICs consist of an asset or collection of assets that are owned by the fund and a benefit-responsive, book value wrap contract purchased for the portfolio. The wrap contract provides book value accounting for the asset and assures that book value, benefit-responsive payments will be made for participant-directed withdrawals from the Stable Value Fund. The crediting rate of the contract is set at the start of the contract and typically resets monthly. The initial crediting rate is established based on the market interest rates at the time the initial asset is purchased but will not be less than 0%.

Constant duration synthetic GICs consist of a portfolio of securities owned by the fund and a benefit-responsive, book value wrap contract purchased for the portfolio. The wrap contract amortizes gains and losses of the underlying securities over the portfolio duration and assures that book value, benefit-responsive payments will be made for participant-directed withdrawals from the Stable Value Fund. The crediting rate on a constant duration synthetic GIC resets every month based on the book value of the contract and the market yield, market value and average duration of the underlying assets. The crediting rate aims at converging the book value of the contract and the market value of the underlying portfolio over the duration of the contract and therefore will be affected by movements in interest rates and/or changes in the market value of the underlying portfolio. The initial crediting rate is established based on the market interest rates at the time the underlying portfolio is first put together but will not be less than 0%.

Withdrawals and transfers resulting from certain events, including employer-initiated events and changes in the qualification of the Plan, may limit the ability of the Stable Value Fund to transact at book or contract value. These events may cause liquidation of all or a portion of a contract at market value. The Plan administrator does not believe that the occurrence of any event that would limit the Plan’s ability to transact at book or contract value is probable. All contracts are fully benefit-responsive.

The components of investments at contract value at December 31, 2023 and 2022 were $146,959,986 and $192,187,109 in Synthetic GICs, respectively, and $5,360,119 and $3,456,796 in cash and equivalents, respectively.

5. FAIR VALUE OF INVESTMENTS

The Plan estimates the fair value of investments using available market information and generally accepted valuation methodologies. Fair value is defined as the price that would be received to sell an asset or would be paid to transfer a liability in an orderly transaction between market participants at the measurement date. The inputs used to measure fair value are classified into three levels: Level 1, defined as observable inputs such as quoted prices in active markets; Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable; and Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions.

The following is a description of the valuation methodologies used for assets measured at fair value:

• Berkshire Hathaway Class B stock fund: Class B shares of Berkshire Hathaway (Symbol BRK-B) are valued at the closing price as reported on the New York Stock Exchange. The fund also consists of temporary investments in the State Street Government Short Term Fund for liquidity purposes and is therefore classified within Level 2 of the valuation hierarchy.

10

• Mutual funds: Valued at the net asset value (“NAV”) as reported on various stock exchanges and classified within Level 1 of the valuation hierarchy.

• Self-directed brokerage accounts: Valued at the NAV of underlying funds as reported on various stock exchanges and classified within Level 1 of the valuation hierarchy.

• Common collective trust funds: Valued using the NAV provided by the administrator of the trust and classified within Level 2 of the valuation hierarchy. The NAV is based on the value of the underlying assets owned by the trust, minus its liabilities, and then divided by the number of shares outstanding.

The methods described above may produce a fair value calculation that may not be indicative of net realizable value or reflective of future fair values. There have been no changes in the methodologies used from 2022 to 2023. Furthermore, while the Plan believes its valuation methods are appropriate and consistent with other market participants, the use of different methodologies or assumptions to determine the fair value of certain financial instruments could result in a different fair value measurement at the reporting date.

The following tables set forth by level, within the fair value hierarchy, the investments of the Plan reported at fair value held by the Plan Trust as of December 31, 2023 and 2022 (in thousands):

	2023
	Level 1		Level 2		Level 3		Total

	$	205,677	$	826,160	$	-	$	1,031,837

6. RISKS AND UNCERTAINTIES

The Plan holds 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.

7. PARTY-IN-INTEREST TRANSACTIONS

The Plan invests in Class B shares of Berkshire Hathaway within the Berkshire Hathaway Class B stock fund. A total of 6,519 and 24,858 Class B shares for 2023 and 2022, respectively, of Berkshire Hathaway at a cost of $1,963,254 and $7,452,979 respectively, were purchased within the fund. All purchased shares were acquired at the then current market value on the open market. In addition, during the years ended December 31, 2023 and 2022, the fund sold or distributed to participants 23,070 and 34,426 Class B shares, respectively, of Berkshire Hathaway and received proceeds of $7,459,094 and $10,277,529, respectively. The realized gains on these sales were $3,530,446 and $4,639,696 for 2023 and 2022, respectively.

Fees charged to individual participant accounts for loan initiations, QDROs and brokerage account maintenance and paid to the Trustee, during the years ended December 31, 2023 and December 31, 2022 were $37,133 and $21,770, respectively. Fees charged to individual participant accounts for investment advice service and paid to Advised Assets Group, LLC during the years ended December 31, 2023 and December 31, 2022 were $566,867and $585,459, respectively.

8. TAX EXEMPT STATUS

The Plan obtained its latest determination letter dated August 24, 2017, in which the Internal Revenue Service stated that the Plan, as then designed, was in compliance with the applicable requirements of Section 401 of the Internal Revenue Code. The Plan has been amended since receiving this determination letter. However, the Company believes that the Plan currently is designed and is being operated in compliance with the applicable requirements of the Internal Revenue Code. Therefore, no provision for income taxes has been included in the Plan’s financial statements.

The Plan administrator has analyzed the tax positions taken by the Plan and has concluded that, as of December 31, 2023, there are no uncertain positions taken or expected to be taken that would require such recognition or disclosure in the financial statements.

9. PLAN TERMINATION

The Plan was adopted with the expectation that it will continue indefinitely. The Company may, however, terminate the Plan at any time. In addition, the management of any subsidiary may withdraw such subsidiary from the Plan at any time. In the event of termination of the Plan, all participants immediately will become fully vested in the value of their account balances.
