Note 9: Financial Instruments

Fair Value

The Company defines fair value as the price that would be received from selling an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. When determining the fair value measurements for assets and liabilities required or permitted to be recorded at fair value, the Company considers the principal or most advantageous market in which it would transact, and it considers assumptions that market participants would use when pricing the asset or liability.

A fair value hierarchy has been established that prioritizes the inputs to valuation techniques used to measure fair value. The level of an asset or liability in the hierarchy is based on the lowest level of input that is significant to the fair value measurement. Assets and liabilities carried at fair value are classified and disclosed in one of the following three categories:

Level 1: Valuations based on quoted prices in active markets for identical assets or liabilities with sufficient volume and frequency of transactions.

Level 2: Valuations based on observable inputs other than Level 1 prices such as quoted prices for similar assets or liabilities, quoted prices in markets that are not active for identical assets or liabilities, or model-derived valuations techniques for which all significant inputs are observable in the market or can be corroborated by observable market data for substantially the full term of the assets or liabilities.

Level 3: Valuations based on unobservable inputs to the valuation methodology that are significant to the measurement of fair value of assets or liabilities and based on non-binding, broker-provided price quotes and may not have been corroborated by observable market data.

The Company engages with pricing vendors to provide fair values for a majority of its Level 1 investments. The vendors provide either a quoted market price or use observable inputs without applying significant adjustments in their pricing. Significant observable inputs include interest rates and yield curves observable at commonly quoted intervals, volatility and credit risks. The fair value of derivative contracts is determined using observable market inputs such as the foreign currency rates, forward rate curves, currency volatility and interest rates and considers nonperformance risk of the Company and its counterparties.

The Company’s primary financial instruments include its cash, cash equivalents, long-term investments, accounts receivable, accounts payable, long-term debt and leases, and foreign currency related derivative instruments. The estimated fair value of cash, time deposits, accounts receivable, and accounts payable approximates their carrying value due to the short period of time to their maturities. The estimated fair values of lease obligations approximate their carrying value as the majority of these obligations are generally short-term in nature and have interest rates that reset upon renewal or modification. Refer to Note 14: Long Term Debt and Other Borrowings for additional information regarding the fair value of the Company’s senior notes.

Lam Research Corporation 2025 10-K 54

The Company accounts for its investment portfolio at fair value. Realized gains (losses) for investment sales are specifically identified. Management assesses the fair value of investments in debt securities that are not actively traded through consideration of interest rates and their impact on the present value of the cash flows to be received from the investments.

The Company evaluates its investments with fair value less than amortized cost by first considering whether the Company has the intent to sell the security or whether it is more likely than not that the Company will be required to sell the security before recovery of its amortized cost basis. In either such situation, the difference between fair value and amortized cost is recognized as a loss in the Consolidated Statement of Operations. Where such sales are not likely to occur, the Company considers whether a portion of the loss is the result of a credit loss. To the extent such losses are the result of credit losses, those amounts are recognized in the Consolidated Statement of Operations. All other differences between fair value and amortized cost are recognized in other comprehensive income. No such losses were recognized through the Consolidated Statement of Operations during the twelve months ended June 29, 2025, June 30, 2024, and June 25, 2023.

Investments

Investments are recorded within Prepaid expenses and other current assets in the Company’s Consolidated Balance Sheets. As of June 29, 2025 and June 30, 2024, the fair value, and associated unrealized loss positions, if any, of mutual funds and debt and equity investments were not material. Gross realized gains/(losses) from sales of investments were insignificant in fiscal years 2025, 2024, and 2023.

The financial instruments reported within Cash and cash equivalents in the Company’s Consolidated Balance Sheets as of June 29, 2025, and June 30, 2024 consisted of the following:

June 29,2025June 30,2024
(in thousands)
Money market funds (fair value measured on a recurring basis, level 1)$3,151,084$2,543,462

Time deposits1,577,3391,736,079
Total$6,390,659$5,847,856

Derivative Instruments and Hedging

The Company carries derivative financial instruments (“derivatives”) on its Consolidated Balance Sheets at their fair values. The Company enters into foreign currency forward contracts and foreign currency options with financial institutions with the primary objective of reducing volatility of earnings and cash flows related to foreign currency exchange rate fluctuations. In addition, the Company enters into interest rate swap arrangements to manage interest rate risk. The counterparties to these derivatives are large, global financial institutions that the Company believes are creditworthy, and therefore, it does not consider the risk of counterparty nonperformance to be material.

Cash Flow Hedges

As of June 29, 2025 and June 30, 2024, the fair value of outstanding cash flow hedges was not material. The effect of derivative instruments designated as cash flow hedges on the Company’s Consolidated Statements of Operations, including accumulated other comprehensive income, was not material as of and for the twelve months ended June 29, 2025 and June 30, 2024. As of June 29, 2025, the Company had an immaterial net gain or loss accumulated in other comprehensive income, net of tax, related to foreign exchange cash flow hedges and interest rate contracts which it expects to reclassify from other comprehensive income into earnings over the next 12 months. The total notional value of cash flow hedge instruments outstanding as of June 29, 2025 included $447.4 million of buy contracts and $323.6 million of sell contracts.

Balance Sheet Hedges

As of June 29, 2025 and June 30, 2024, the fair value of outstanding balance sheet hedges was not material. The effect of the Company’s balance sheet hedge derivative instruments on the Company’s Consolidated Statements of Operations were not material as of and for the twelve months ended June 29, 2025. The total notional value of balance sheet hedge instruments outstanding as of June 29, 2025 included $281.1 million of buy contracts and $121.5 million of sell contracts.

Concentrations of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist principally of cash and cash equivalents, trade accounts receivable, and derivative financial instruments used in hedging activities. Cash is placed on deposit at large, global financial institutions. Such deposits may be in excess of insured limits. Management believes that the financial institutions that hold the Company’s cash are creditworthy and, accordingly, minimal credit risk exists with respect to these balances.

Lam Research Corporation 2025 10-K 55

The Company’s overall portfolio of available-for-sale securities must maintain an average minimum rating of “AA-” or “Aa3” as rated by Standard and Poor’s, Fitch Ratings, or Moody’s Investor Services. To ensure diversification and minimize concentration, the Company’s policy limits the amount of credit exposure with any one financial institution or commercial issuer.

The Company is exposed to credit losses in the event of nonperformance by counterparties on foreign currency and interest rate hedge contracts that are used to mitigate the effect of exchange rate and interest rate fluctuations and on contracts related to structured share repurchase arrangements. These counterparties are large, global financial institutions and, to date, no such counterparty has failed to meet its financial obligations to the Company.

Credit risk evaluations, including trade references, bank references, and Dun & Bradstreet ratings, are performed on all new customers, and the Company monitors its customers’ financial condition and payment performance. In general, the Company does not require collateral on sales.

As of June 29, 2025, three customers accounted for approximately 19%,15% and 12% of accounts receivable, respectively. As of June 30, 2024, three customers accounted for approximately 16%,13%, and 13% of accounts receivable, respectively. No other customers accounted for 10% or more of accounts receivable. The Company’s balance and transactional activity for its allowance for doubtful accounts is not material as of and for the years ended June 29, 2025, June 30, 2024, and June 25, 2023. Refer to Note 19: Segment, Geographic Information, and Major Customers for additional information regarding customer concentrations.

Note 15: Leases

The Company leases certain office spaces, manufacturing and warehouse spaces, equipment, and vehicles. While the majority of the Company’s lease arrangements are operating leases, the Company has certain leases that qualify as finance leases.

Variable lease payments are expensed as incurred and are not included within the right of use asset and lease liability calculation. Variable lease payments primarily include costs associated with the Company’s third-party logistics arrangements that contain one or more embedded leases. Variable lease costs will fluctuate based on factory output and material receipt volumes. Variable lease costs for fiscal years 2025, 2024, and 2023 were $176.6 million, $176.6 million, and $227.7 million; respectively. Finance lease costs, including amortization of right of use assets and interest on lease liabilities; short-term rental expense for agreements less than one year in duration; and operating lease costs were immaterial for fiscal years 2025, 2024, and 2023, respectively.

The Company leases some of its administrative, research and development and manufacturing facilities, regional sales/service offices, and certain equipment under non-cancelable leases. Certain of the Company’s facility leases are for buildings located at its Tualatin, Oregon campus; and certain other facility leases provide the Company with options to extend the leases for additional periods or to purchase the facilities. Certain of the Company’s facility leases provide for periodic rent increases based on the general rate of inflation.

Lam Research Corporation 2025 10-K 60

The Company elected to exercise purchase options available under its finance leases for certain improved properties in Fremont and Livermore, California (the “California Facility Leases”) in the three months ended September 24, 2023. As a result, the Company released cash collateral in an aggregate of approximately $250 million of restricted cash that was reported in Other assets in the Company’s Consolidated Balance Sheet. Additionally, guarantees made to the lessor that each property would have a certain minimum residual value totaling $298.4 million as of June 25, 2023 in the aggregate were eliminated with the extinguishment of the California Facility Leases. As a result of the purchase of the improved properties, $250.5 million of additions were made to Property and equipment, net in the Company’s Consolidated Balance Sheets primarily comprised of land ($40.5 million) and buildings and improvements ($210.0 million).

Note 16: Deferred Compensation Plans

The Company has an unfunded, non-qualified deferred compensation plan whereby executives may defer a portion of their compensation. Participants earn a return on their deferred compensation based on their allocation of their account balance among various mutual funds. The Company controls the investment of these funds, and the participants remain general creditors of the Company. Participants are able to elect the payment of benefits on a specified date at least three years after the opening of a deferral sub-account or upon retirement. Distributions are made in the form of lump sum or annual installments over a period of up to 20 years as elected by the participant. If no alternate election has been made, a lump sum payment will be made upon termination of a participant’s employment with the Company. As of June 29, 2025, and June 30, 2024, the liability of the Company to the plan participants was $423.9 million and $385.5 million, respectively, which was recorded in Accrued expenses and other current liabilities and Other long-term liabilities on the Consolidated Balance Sheets. As of June 29, 2025, and June 30, 2024, the Company had investments in the aggregate amount of $438.8 million and $393.5 million, respectively, which correlate to the deferred compensation obligations, which were recorded in Other assets on the Consolidated Balance Sheets.

Note 17: Commitments and Contingencies

The Company has certain obligations to make future payments under various contracts; some of these are recorded on its balance sheet and some are not. Obligations that are recorded on the Company’s balance sheet include the Company’s operating and finance lease obligations. Obligations that are not recorded on the Company’s balance sheet include contractual relationships for purchase obligations and certain guarantees. The Company’s commitments relating to off-balance sheet agreements are included in the tables below. These amounts exclude $635.4 million of liabilities related to uncertain tax positions (see Note 7: Income Taxes for further discussion) as of the end of the fiscal year because the Company is unable to reasonably estimate the ultimate amount or time of settlement.

Other Guarantees

The Company has issued certain indemnifications to its lessors for taxes and general liability under some of its agreements. The Company has entered into insurance contracts that are intended to limit its exposure to such indemnifications. As of June 29, 2025, the Company had not recorded any liability on its Consolidated Financial Statements in connection with these indemnifications, as it does not believe that it is probable that any material amounts will be paid under these guarantees.

Generally, the Company indemnifies, under pre-determined conditions and limitations, its customers for infringement of third-party intellectual property rights by the Company’s products or services. The Company seeks to limit its liability for such indemnity to an amount not to exceed the sales price of the products or services subject to its indemnification obligations. The Company does not believe that it is probable that any material amounts will be paid under these guarantees.

The Company provides guarantees and standby letters of credit to certain parties as required for certain transactions initiated during the ordinary course of business. As of June 29, 2025, the maximum potential amount of future payments that the Company could be required to make under these arrangements and letters of credit was $218.8 million. The Company does not believe, based on historical experience and information currently available, that it is probable that any material amounts will be required to be paid.

In addition, the Company has entered into indemnification agreements with its directors, officers, and certain other employees, consistent with its Bylaws and Certificate of Incorporation; and under local law, the Company may be required to provide indemnification to its employees for actions within the scope of their employment. Although the Company maintains insurance contracts that cover some of the potential liability associated with these indemnification agreements, there is no guarantee that all such liabilities will be covered. The Company does not believe, based on historical experience and information currently available, that it is probable that any material amounts will be required to be paid under such indemnification agreements or statutory obligations.

Transition Tax Liability

On December 22, 2017, the “Tax Cuts & Jobs Act” was signed into law. Among other items, this U.S. tax reform assessed a one-time transition tax on earnings of certain foreign subsidiaries that were previously tax deferred. As a result, the Company recognized a total transition tax of $868.4 million and elected to pay the one-time tax over a period of 8 years, commencing in the twelve months ended June 30, 2019. During fiscal year 2023, this one-time tax was adjusted, resulting in a total tax liability increase of approximately $50.0 million, which was spread over the same 8-year period. The remaining obligation related to this arrangement totals $229.6 million and is expected to be paid in fiscal year 2026. The Company may choose to apply existing tax credits, thereby reducing the actual cash payment.

Warranties

The Company provides standard warranties on its systems. The liability amount is based on actual historical warranty spending activity by type of system, customer, and geographic region, modified for any known differences such as the impact of system reliability improvements. As of June 29, 2025, warranty reserves totaling $16.7 million were reported in Other long-term liabilities, and the remainder were included in Accrued expenses and other current liabilities in the Company’s Consolidated Balance Sheets.

Changes in the Company’s product warranty reserves were as follows:

Government Assistance

In the fiscal years ended June 29, 2025 and June 30, 2024, the Company received government assistance from various domestic and international governments in the form of cash grants or refundable tax credits. The Grants typically specify conditions that must be met in order for the Grants to be earned, such as employment or employee retention targets; completion of employee training; or the construction or acquisition of property and equipment and are often time-bound. If conditions are not satisfied or if the duration period for the arrangement is not met, the Grants are often subject to reduction, repayment, or termination.

During the fiscal years ended June 29, 2025 and June 30, 2024, the Company’s cash Grants were insignificant. During the fiscal years ended June 29, 2025 and June 30, 2024, the Company recognized immaterial reductions to the cost basis of acquired property and equipment related to refundable tax credits earned. This reduction in the cost basis of acquired property and equipment is recorded with a corresponding reduction to taxes payable and classified under Accrued expense and other current liabilities, or Other long-term liabilities, as appropriate, in the Consolidated Balance Sheets.

While the Company is not currently a party to any legal proceedings that it believes material, the Company is either a defendant or plaintiff in various actions that have arisen from time to time in the normal course of business, including intellectual property claims. The Company accrues for a liability when it is both probable that a liability has been incurred and the amount of the loss can be reasonably estimated. Judgment is required in both the determination of probability and the determination as to whether a loss is reasonably estimable. Based on current information, the Company does not believe that a material loss from known matters is probable and therefore has not recorded an accrual of any material amount for litigation or other contingencies related to existing legal proceedings.

Note 18: Stock Repurchase Program

In May 2024, the Board of Directors authorized the Company to repurchase up to an additional $10.0 billion of Common Stock; this authorization supplements the remaining balances from any prior authorizations. These repurchases can be conducted on the open market or as private purchases and may include the use of derivative contracts with large financial institutions, in all cases subject to compliance with applicable law. This repurchase program has no termination date and may be suspended or discontinued at any time.

Repurchases under the repurchase program were as follows during the periods indicated:

(2) Includes shares received at initial settlement of accelerated share repurchase agreements; see additional disclosures below regarding the Company’s accelerated share repurchase activity during the fiscal year.

(3) The Company’s net share repurchases are subject to a 1% excise tax under the Inflation Reduction Act. Excise tax incurred reduces the amount available under the repurchase program, as applicable, and is included in the cost of shares repurchased in the Consolidated Statement of Stockholders’ Equity and the calculation of the average price paid per share.

Accelerated Share Repurchase Agreements

On April 30, 2025, the Company entered into accelerated share repurchase agreements (the "April 2025 ASRs") withtwo financial institutions to repurchase a total of $500 million of Common Stock. The Company took an initial delivery of approximately 5.2 million shares, which represented 75% of the prepayment amount divided by our closing stock price on April 30, 2025. The total number of shares received under the April 2025 ASRs will be based upon the average daily volume weighted average price of the Company’s Common Stock during the repurchase period, less an agreed upon discount. Final settlement of the April 2025 ASRs will occur no later than September 8, 2025.

The Company recorded the April 2025 ASRs as equity transactions; as such, at the time of receipt, shares were included in treasury stock at fair market value as of the corresponding trade date. The Company reflects shares received as a repurchase of common stock in the weighted average common shares outstanding calculation for basic and diluted earnings per share.

Note 19: Segment, Geographic Information, and Major Customers

The Company operates inone reportable business segment: manufacturing and servicing of wafer processing semiconductor manufacturing equipment. The Company’s material operating segments qualify for aggregation due to their customer base and similarities in economic characteristics, nature of products and services, and processes for procurement, manufacturing, and distribution. The Company's chief operating decision maker (“CODM”) is the Company's Chief Executive Officer.

The Company's CODM utilizes segment gross margin as the measure of profit or loss to evaluate operating segment profitability and to assess the allocation of resources. Segment gross margin excludes both routine and non-routine expenses that are not allocated to the reportable segment, including, but not limited to, amortization of intangible assets acquired in certain business combinations, the change in value of the Company's elective deferred compensation-related liability, restructuring charges, impairment of long-lived assets, and transformational charges.

Segment results are derived from the Company's internal management reporting system utilizing policies that are substantially the same as those used for external reporting purposes. The CODM utilizes segment revenue growth in conjunction with segment gross margin metrics in comparing forecast to actual results as well as in benchmarking to the Company's peer group.

The Company's centralized manufacturing and support organizations, including global operations and certain administrative functions, provide support to its operating segments. Costs incurred by these organizations, as well as depreciation and amortization and equity-based compensation expense are allocated to cost of goods sold as overhead. Consequently, depreciation and amortization and equity-based compensation expense are not independently identifiable components within the segment’s results, and, therefore are not provided.

With the exception of goodwill, the Company does not identify assets by operating segment. Consequently, the CODM does not regularly review or receive discrete asset information by operating segment.

The table below reconciles the Company's reportable segment to income before income taxes:

The Company operates inseven geographic regions: United States, China, Europe, Japan, Korea, Southeast Asia, and Taiwan. For geographical reporting, revenue is attributed to the geographic location in which the customers’ facilities are located, while long-lived assets; which includes property and equipment, net, and recognized right of use assets reported in Other assets in the Consolidated Balance Sheets as of June 29, 2025 and June 30, 2024; are attributed to the geographic locations in which the assets are located.

Note 20: Restructuring Charges, Net

The Company records employee severance and separation costs that meet the requirements for recognition in accordance with the relevant guidance of ASC 420, Exit or Disposal Cost Obligations, or ASC 712, Compensation - Non-retirement Post-employment Benefits, as applicable. For involuntary termination benefits that are not provided under the terms of an ongoing benefit arrangement, the liability for the current fair value of expected future costs associated with a management-approved restructuring plan is recognized in the period in which the plan is communicated to the employees and the plan is not expected to change significantly. For ongoing benefit arrangements, inclusive of statutory requirements, employee termination costs are accrued when the existing situation or set of circumstances indicates that an obligation has been incurred, it is probable the benefits will be paid, and the amount can be reasonably estimated. Termination benefits associated with employees that elected to voluntarily terminate as part of the restructuring plan are recorded when the employee irrevocably accepts the offer and the amount can be reasonably estimated. If applicable, the Company records such costs into operating expense over the terminated employees’ future service period beyond any minimum or legally required retention period. The majority of restructuring charges that have been incurred but not yet paid are recorded in Accrued expenses and other current liabilities in the Consolidated Balance Sheets.

Lam Research Corporation 2025 10-K 65

During the fiscal year ended June 25, 2023, the Company initiated a restructuring plan designed to better align the Company’s cost structure with its outlook for the economic environment and business opportunities. Under the plan, through June 30, 2024, the Company terminated approximately 1,760 employees, incurring expenses related to employee severance and separation costs. Employee severance and separation costs are primarily related to severance, non-cash severance, including equity award compensation expense, pension and other termination benefits. Additionally, the Company made a strategic decision to relocate certain manufacturing activities to pre-existing facilities and incurred charges to move inventory and equipment and exit selected supplier arrangements.

No restructuring costs were recorded during the fiscal year ended June 29, 2025. During the fiscal year ended June 30, 2024, net restructuring costs of $43.4 million and $18.2 million were recorded in Restructuring charges, net - cost of goods sold, and Restructuring charges, net - operating expenses, respectively in the Consolidated Statements of Operations.

The restructuring plan was substantially completed as of June 30, 2024, and cumulative costs as of June 30, 2024 totaled $181.9 million. The restructuring liability reported as of June 30, 2024 totaling $1.1 million was substantially satisfied in the three months ended September 29, 2024.

Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Lam Research Corporation (the Company) as of June 29, 2025 and June 30, 2024, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended June 29, 2025, and the related notes (collectively referred to as the “consolidated financial statements”). In our opinion, the consolidated financial statements present fairly, in all material respects, the financial position of the Company at June 29, 2025 and June 30, 2024, and the results of its operations and its cash flows for each of the three years in the period ended June 29, 2025, in conformity with U.S. generally accepted accounting principles.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of June 29, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework), and our report dated August 11, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the financial statements that was communicated or required to be communicated to the audit committee and that: (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective or complex judgments. The communication of the critical audit matter does not alter in any way our opinion on the consolidated financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the account or disclosure to which it relates.

Inventory - Valuation
Description of the MatterThe Company’s inventories totaled $4.3 billion as of June 29, 2025, representing 20% of total assets. As explained in Note 2 to the consolidated financial statements, the Company assesses the valuation of all inventories including manufacturing raw materials, work-in-process, finished goods, and spare parts in each reporting period. Inventory in excess of management’s estimated usage requirement and obsolete inventory is written down to its estimated net realizable value if less than cost.Auditing management’s estimates for certain excess and obsolete inventory involved subjective auditor judgment because management’s assessment of whether a write down is required and the measurement of any excess of cost over net realizable value is judgmental and considers a number of qualitative factors that are affected by market and economic conditions outside the Company’s control.
How We Addressed the Matter in Our AuditWe evaluated and tested the Company’s processes and the design and operating effectiveness of internal controls addressing the identified audit risks. This included controls over management’s assessment of inventory valuation, including the development of forecasted usage of inventories and consideration of how factors outside of the Company’s control might affect management’s judgment related to the valuation of excess and obsolete inventory. Our audit procedures included, among others, evaluating the significant assumptions (e.g., forecasts related to the Company’s future manufacturing schedules, customer demand, technological obsolescence, and possible alternative uses) and the underlying data used in management’s excess and obsolete inventory valuation assessment. We evaluated inventory levels compared to forecasted demand, historical sales and specific product considerations. We also assessed the historical accuracy of management’s estimates.

Opinion on Internal Control Over Financial Reporting

We have audited Lam Research Corporation’s internal control over financial reporting as of June 29, 2025, based on criteria established in Internal Control—Integrated Framework issued by the Committee of Sponsoring Organizations of the Treadway Commission (2013 framework) (the COSO criteria). In our opinion, Lam Research Corporation (the Company) maintained, in all material respects, effective internal control over financial reporting as of June 29, 2025, based on the COSO criteria.

We also have audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the consolidated balance sheets of the Company as of June 29, 2025 and June 30, 2024, the related consolidated statements of operations, comprehensive income, stockholders’ equity and cash flows for each of the three years in the period ended June 29, 2025, and the related notes and our report dated August 11, 2025 expressed an unqualified opinion thereon.

Basis for Opinion

The Company’s management is responsible for maintaining effective internal control over financial reporting and for its assessment of the effectiveness of internal control over financial reporting included in the accompanying Management’s Report on Internal Control over Financial Reporting. Our responsibility is to express an opinion on the Company’s internal control over financial reporting based on our audit. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company 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 effective internal control over financial reporting was maintained in all material respects.

Our audit included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, testing and evaluating the design and operating effectiveness of internal control based on the assessed risk, and performing such other procedures as we considered necessary in the circumstances. We believe that our audit provides a reasonable basis for our opinion.

Definition and Limitations of Internal Control Over Financial Reporting

A company’s internal control over financial reporting is a process designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. A company’s internal control over financial reporting includes those policies and procedures that (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of the company; (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with generally accepted accounting principles, and that receipts and expenditures of the company are being made only in accordance with authorizations of management and directors of the company; and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use, or disposition of the company’s assets that could have a material effect on the financial statements.

Because of its inherent limitations, internal control over financial reporting may not prevent or detect misstatements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree of compliance with the policies or procedures may deteriorate.
