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 2026 10-K 59

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 28, 2026, June 29, 2025, and June 30, 2024.

Investments

Investments are recorded within Prepaid expenses and other current assets in the Company’s Consolidated Balance Sheets. As of June 28, 2026 and June 29, 2025, the fair value, and associated unrealized loss positions, if any, of mutual funds and equity investments were not material. Gross realized gains/(losses) from sales of investments were insignificant in fiscal years 2026, 2025, and 2024.

The financial instruments reported within Cash and cash equivalents in the Company’s Consolidated Balance Sheets as of June 28, 2026, and June 29, 2025 consisted of the following:

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 28, 2026 and June 29, 2025, 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 28, 2026 and June 29, 2025. As of June 28, 2026, 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 28, 2026 included $615.4 million of buy contracts and $438.5 million of sell contracts.

Balance Sheet Derivative Instruments

As of June 28, 2026 and June 29, 2025, the fair value of outstanding balance sheet derivative instruments was not material. The effect of the Company’s balance sheet derivative instruments on the Company’s Consolidated Statements of Operations were not material as of and for the twelve months ended June 28, 2026. The total notional value of balance sheet derivative instruments outstanding as of June 28, 2026 included $359.6 million of buy contracts and $576.2 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. To ensure diversification and minimize concentration, the Company’s policy limits the amount of credit exposure with any one financial institution.

Lam Research Corporation 2026 10-K 60

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 28, 2026, five customers accounted for approximately 20%,16%,15%,11%, and 10% of accounts receivable, respectively. As of June 29, 2025, three customers accounted for approximately 19%,15%, and 12% 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 28, 2026, June 29, 2025, and June 30, 2024. Refer to Note 19: Segment, Geographic Information, and Major Customers for additional information regarding customer concentrations.

Selected additional information regarding the Senior Notes outstanding as of June 28, 2026, is as follows:

Revolving Credit Facility

On March 12, 2014, the Company established an unsecured Credit Agreement. This agreement was amended on November 10, 2015 (the “Amended and Restated Credit Agreement”), October 13, 2017 (the “2nd Amendment”), February 25, 2019 (the “3rd Amendment”), June 17, 2021 (the “Second Amended and Restated Credit Agreement”), December 7, 2022 (“Amendment No.1 to Second Amended and Restated Credit Agreement”), and January 27, 2025 (the “Third Amended and Restated Credit Agreement”). The Third Amended and Restated Credit Agreement provides for a $2.00 billion revolving credit facility with a syndicate of lenders, along with an expansion option that will allow the Company, subject to certain requirements, to request an increase in the facility of up to an additional $750.0 million, for a potential total commitment of $2.75 billion. The facility matures on January 25, 2030.

Interest on amounts borrowed under the credit facility is, at the Company’s option, based on (1) a base rate, plus a spread of 0.00% to 0.10%, or (2) an adjusted term Secured Overnight Financing Rate, plus a spread of 0.70% to 1.10%, in each case plus a facility fee, with such spread and facility fee determined in accordance with the Third Amended and Restated Credit Agreement, and with the spread and facility fee based on the rating of the Company’s non-credit enhanced, senior unsecured long-term debt. Principal and any accrued and unpaid interest are due and payable upon maturity. Additionally, the Company will pay the lenders a quarterly commitment fee that varies based on the Company’s credit rating as described above. As of June 28, 2026, the Company hadno borrowings outstanding under the credit facility and was in compliance with all financial covenants.

Commercial Paper Program

In November 2017, the Company established a commercial paper program (the “CP Program”) under which the Company may issue unsecured commercial paper notes on a private placement basis up to a maximum aggregate principal amount of $1.25 billion. In July 2021, the Company amended the CP Program size to a maximum aggregate amount outstanding at any time of $1.50 billion. In March 2026, the CP Program size was further amended to a maximum aggregate amount outstanding at any time of $2.00 billion. The net proceeds from the CP Program may be used for general corporate purposes, including repurchases of the Company’s Common Stock from time to time under the Company’s stock repurchase program. Amounts available under the CP Program may be re-borrowed. The CP Program is backstopped by the Company’s Revolving Credit Arrangement. As of June 28, 2026, the Company hadno outstanding borrowings under the CP Program.

Interest Cost

The following table presents the amount of interest cost recognized relating to both the contractual interest coupon and amortization of the debt discount, issuance costs, and effective portion of interest rate contracts with respect to the Senior Notes, and the revolving credit facility during the fiscal years ended June 28, 2026, June 29, 2025, and June 30, 2024.

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.

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 provide the Company with options to extend the leases for additional periods, to purchase the facilities, or provide for periodic rent increases based on the general rate of inflation.

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 2026, 2025, and 2024 were $165.9 million, $176.6 million, and $176.6 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 2026, 2025, and 2024, respectively.

Supplemental cash flow information related to leases was as follows as of June 28, 2026, June 29, 2025, and June 30, 2024:

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 28, 2026, and June 29, 2025, the liability of the Company to the plan participants was $498.5 million and $423.9 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 28, 2026, and June 29, 2025, the Company had investments in the aggregate amount of $511.8 million and $438.8 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 $762.4 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.

Lam Research Corporation 2026 10-K 65

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 28, 2026, the Company had not recorded any liability on its Consolidated Financial Statements in connection with these indemnifications, as it does not believe, based on historical experience and information currently available, 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, based on historical experience and information currently available, 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 28, 2026, the maximum potential amount of future payments that the Company could be required to make under these arrangements and letters of credit was $275.1 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.

Purchase Obligations

Purchase obligations consist of non-cancelable significant contractual obligations either on an annual basis or over multi-year periods. The contractual cash obligations and commitments table presented below contains the Company’s minimum obligations at June 28, 2026, under these arrangements and others. For obligations with cancellation provisions, the amounts included in the following table were limited to the non-cancelable portion of the agreement terms or the minimum cancellation fee. Actual expenditures will vary based on the volume of transactions and length of contractual service provided.

The Company’s commitments related to these agreements as of June 28, 2026, were as follows:

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 was settled in fiscal year 2026.

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 28, 2026, warranty reserves totaling $19.7 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.

Lam Research Corporation 2026 10-K 66

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

Government Assistance

In the fiscal years ended June 28, 2026 and June 29, 2025, 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 28, 2026 and June 29, 2025, the Company’s cash Grants were insignificant. During the fiscal years ended June 28, 2026 and June 29, 2025, 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 $10.00 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:

(1) 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.

(2) Average price paid per share excludes the effect of accelerated share repurchase activities. See additional disclosure below regarding the Company’s accelerated share repurchase activity during the fiscal year.

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

Lam Research Corporation 2026 10-K 67

Accelerated Share Repurchase Agreements

On March 11, 2026, the Company entered into an accelerated share repurchase agreement (the “March 2026 ASR”) with a financial institution to repurchase a total of $200.0 million of Common Stock. The Company took an initial delivery of approximately 685 thousand shares, which represented 75% of the prepayment amount divided by the Company’s closing stock price on March 11, 2026. The total number of shares received under the March 2026 ASR was 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 March 2026 ASRs occurred in June 2026, resulting in the receipt of approximately 55 thousand additional shares, which yielded a weighted-average share price of $270.71 for the transaction period, including the effects of a 1% excise tax under the Inflation Reduction Act

On April 30, 2025, the Company entered into accelerated share repurchase agreements (the "April 2025 ASRs") withtwo financial institutions to repurchase a total of $500.0 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 the Company’s closing stock price on April 30, 2025. The total number of shares received under the April 2025 ASRs was 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 occurred in September 2025, resulting in the receipt of approximately 317 thousand additional shares, which yielded a weighted-average share price of $91.00 for the transaction period, including the effects of a 1% excise tax under the Inflation Reduction Act.

The Company recorded each of the 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.

Lam Research Corporation 2026 10-K 68

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

(1)Other COGS is primarily comprised of the capitalized cost of inventory sold, including both direct and indirect costs, but excludes installation and warranty expense and those items not allocated to the segment.

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 28, 2026 and June 29, 2025; are attributed to the geographic locations in which the assets are located.

Revenues and long-lived assets by geographic region were as follows:

Lam Research Corporation 2026 10-K 69

In fiscal year 2026, four customers accounted for approximately 16%,15%,12%, and 12% of total revenues, respectively. In fiscal year 2025, two customer accounted for approximately 17% and 15% of total revenues. In fiscal year 2024, one customer accounted for approximately 17% of total revenues, respectively. No other customers accounted for 10% or more of total revenues.

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.

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 28, 2026 or 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 associated restructuring liability was substantially satisfied in the three months ended September 29, 2024.

We have audited the accompanying consolidated balance sheet of Lam Research Corporation (the Company) as of June 28, 2026, the related consolidated statements of operations, comprehensive income, stockholders’ equity, and cash flows for the year then ended, and the related notes (collectively, the consolidated financial statements). We also have audited the Company’s internal control over financial reporting as of June 28, 2026, based on criteria established in Internal Control – Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission.

In our opinion, the consolidated financial statements referred to above present fairly, in all material respects, the financial position of the Company as of June 28, 2026, and the results of its operations and its cash flows for the year then ended, in conformity with U.S. generally accepted accounting principles. Also in our opinion, the Company maintained, in all material respects, effective internal control over financial reporting as of June 28, 2026 based on criteria established in Internal Control – Integrated Framework (2013)issued by the Committee of Sponsoring Organizations of the Treadway Commission.

Basis for Opinions

The Company’s management is responsible for these consolidated financial statements, 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 consolidated financial statements and an opinion on the Company’s internal control over financial reporting 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 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 audits to obtain reasonable assurance about whether the consolidated financial statements are free of material misstatement, whether due to error or fraud, and whether effective internal control over financial reporting was maintained in all material respects.

Our audit of the consolidated financial statements included performing procedures to assess the risks of material misstatement of the consolidated 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 consolidated 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 consolidated financial statements. Our audit of internal control over financial reporting included obtaining an understanding of internal control over financial reporting, assessing the risk that a material weakness exists, and testing and evaluating the design and operating effectiveness of internal control based on the assessed risk. Our audits also included performing such other procedures as we considered necessary in the circumstances. We believe that our audits provide a reasonable basis for our opinions.

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.

Critical Audit Matter

The critical audit matter communicated below is a matter arising from the current period audit of the consolidated 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 consolidated financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of a 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 accounts or disclosures to which it relates.

Evaluation of sufficiency of audit evidence over revenue

As discussed in Notes 2, 4, and 19 to the consolidated financial statements, the Company recorded $23,232,690 thousand in revenue for the year ended June 28, 2026. The Company generates revenue by designing, manufacturing, refurbishing, and servicing semiconductor processing equipment used in the fabrication of integrated circuits. The Company’s process to account for and recognize revenue differs across revenue streams.

We identified the evaluation of the sufficiency of audit evidence obtained over revenue as a critical audit matter. Evaluating the sufficiency of audit evidence required subjective auditor judgment due to the number of revenue streams and separate processes to account for and recognize revenue. This included determining the nature and extent of audit evidence obtained over each revenue stream.

The following are the primary procedures we performed to address this critical audit matter. We applied auditor judgment to determine the revenue streams over which procedures were performed as well as the nature and extent of such procedures. For revenue streams where procedures were performed, we:

•evaluated the design and tested the operating effectiveness of certain internal controls over the Company’s revenue recognition processes, including the Company’s controls over the accurate recording of revenue

•evaluated the Company’s revenue recognition accounting policies

•evaluated, for a sample of revenue transactions, (1) the accounting for consistency with the Company’s accounting policies, as applicable, including timing of revenue recognition, and (2) the recorded amounts by comparing them for consistency to underlying documentation, including the customer contracts.

In addition, we evaluated the sufficiency of audit evidence obtained by assessing the results of the procedures performed, including the appropriateness of the nature and extent of audit effort over revenue.
