Accounting Policies [Abstract]
DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES	DESCRIPTION OF BUSINESS AND SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES Description of Business and Principles of Consolidation. KLA Corporation and its majority-owned subsidiaries (“KLA” or the “Company” and also referred to as “we,” “our,” “us” or similar references) is a supplier of process equipment, process control equipment, and data analytics products for a broad range of industries, including semiconductors and printed circuit boards (“PCB”). We provide advanced process control and process-enabling solutions for manufacturing and testing wafers and reticles, integrated circuits (“IC”), advanced packaging, light-emitting diodes, power devices, compound semiconductor devices, microelectromechanical systems (“MEMS”), data storage and PCBs as well as general materials research. We also provide comprehensive support and services across our installed base. Our extensive portfolio of inspection, metrology and data analytics products, and related services, helps IC manufacturers achieve target yield throughout the entire semiconductor fabrication process, from research and development (“R&D”) to final volume production. We develop and sell advanced vacuum deposition and etching process tools, which are used by a broad range of specialty semiconductor customers. We enable electronic device manufacturers to inspect, test and measure PCBs and ICs to verify their quality, deposit a pattern of desired electronic circuitry on the relevant substrate and perform three-dimensional shaping of metalized circuits on multiple surfaces. Our advanced products, coupled with our unique yield management software and services, allow us to deliver the solutions our semiconductor and PCB customers need to achieve their productivity goals by significantly reducing their risks and costs and improving their overall profitability and return on investment. Headquartered in Milpitas, California, we have subsidiaries both in the U.S. and key markets throughout the world. The Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. Comparability. Certain reclassifications have been made to the prior year’s Consolidated Financial Statements to conform to the current year presentation. The reclassifications did not have material effects on the prior year’s Consolidated Balance Sheets, Statements of Operations, Comprehensive Income and Cash Flows. Management Estimates. The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in applying our accounting policies that affect the reported amounts of assets and liabilities (and related disclosure of contingent assets and liabilities) at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Cash Equivalents and Fixed Income Marketable Securities . All highly liquid debt instruments with original or remaining maturities of less than three months at the date of purchase are cash equivalents. Fixed income marketable securities are generally classified as available-for-sale for use in current operations, if required, and are reported at fair value, with unrealized gains and non-credit related unrealized losses, net of tax, presented as a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income (loss).” All realized gains and losses are recorded in earnings in the period of occurrence. The specific identification method is used to determine the realized gains and losses on investments. We regularly review the available-for-sale debt securities in an unrealized loss position and evaluate the current expected credit loss by considering available information relevant to the collectability of the security, such as historical experience, market data, issuer-specific factors including credit ratings, default and loss rates of the underlying collateral and structure and credit enhancements, current economic conditions and reasonable and supportable forecasts. There were no credit losses on available-for-sale debt securities recognized in the years ended June 30, 2024, 2023 and 2022. If we do not expect to recover the entire amortized cost of the security, the amount representing credit losses, defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the debt security, is recorded as an allowance for credit losses with an offsetting entry to net income, and the amount that is not credit-related is recognized in other comprehensive income (loss) (“OCI”). If we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its entire amortized cost basis, we first write off any previously recognized allowance for credit losses with an offsetting entry to the security’s amortized cost basis. If the allowance has been fully written off and fair value is less than amortized cost basis, we write down the amortized cost basis of the security to its fair value with an offsetting entry to net income. Investments in Equity Securities. We hold equity securities in publicly and privately held companies for the promotion of business and strategic objectives. Equity securities in publicly held companies, or marketable equity securities, are measured and recorded at fair value on a recurring basis. Equity securities in privately held companies, or non-marketable equity securities, are accounted for at cost, less impairment, plus or minus observable price changes in orderly transactions for identical or similar securities of the same issuer. Non-marketable equity securities are subject to a periodic impairment review; however, since there are no open-market valuations, the impairment analysis requires significant judgment. This analysis includes assessment of the investee’s financial condition, the business outlook for its products and technology, its projected results and cash flow, financing transactions subsequent to the acquisition of the investment, the likelihood of obtaining subsequent rounds of financing and the impact of any relevant contractual equity preferences held by us or the others. Non-marketable equity securities are included in “Other non-current assets” on the balance sheet. Realized and unrealized gains and losses resulting from changes in fair value or the sale of our marketable and non-marketable equity securities are recorded in Other expense (income), net. Variable Interest Entities. We use a qualitative approach in assessing the consolidation requirement for variable interest entities. The approach focuses on identifying which enterprise has the power to direct the activities that most significantly impact the variable interest entity’s economic performance and which enterprise has the obligation to absorb losses or the right to receive benefits from the variable interest entity. In the event we are the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity will be included in our Consolidated Financial Statements. We have concluded that none of our equity investments require consolidation based on our most recent qualitative assessment. Inventory Valuation. Inventories are stated at the lower of cost or net realizable value using standard costs that approximate actual costs on a first-in, first-out basis. The carrying value of product inventory is reduced for estimated obsolescence equal to the difference between its cost and the estimated net realizable value based on assumptions about future demand for meeting our product manufacturing plans. The carrying value of service inventory is reduced for estimated obsolescence equal to the difference between its cost and the estimated net realizable value based on assumptions about future demand to meet our customers’ support requirements. Demonstration units are stated at their manufacturing cost and written down to their net realizable value. The Company’s policy is to assess the valuation of all inventories including manufacturing raw materials, work-in-process, finished goods and spare parts in each reporting period. The estimate of net realizable value of inventory is impacted by assumptions regarding general semiconductor market conditions, manufacturing schedules, technology changes, new product introductions and possible alternative uses, and require us to use significant judgment that may include uncertain elements. Actual demand may differ from forecasted demand, and such differences may have a material effect on recorded inventory values. Our manufacturing overhead standards for product costs are calculated assuming full absorption of forecasted spending over projected volumes, adjusted for excess capacity. Abnormal inventory costs such as costs of idle facilities, excess freight and handling costs and spoilage are recognized as current period charges. Allowance for Credit Losses. A majority of our accounts receivable are derived from sales to large multinational semiconductor and electronics manufacturers throughout the world. We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as selling, general and administrative (“SG&A”) expense in the Consolidated Statements of Operations. We assess collectability by reviewing accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when we identify specific customers with known disputes or collectability issues. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance. Our assessment considered estimates of expected credit and collectability trends. The credit losses recognized on accounts receivable were not significant as of June 30, 2024 and 2023 . Volatility in market conditions and evolving credit trends are difficult to predict and may cause variability that may have a material impact on our allowance for credit losses in future periods. Property and Equipment. Property and equipment are recorded at cost, net of accumulated depreciation. Depreciation of property and equipment is based on the straight-line method over the estimated useful lives of the assets. The following table sets forth the estimated useful life for various asset categories: Asset Category Range of Useful Lives Buildings 30 to 50 years Leasehold improvements Shorter of 15 years or lease term Machinery and equipment 2 to 10 years Office furniture and fixtures 7 years Construction-in-process assets are not depreciated until the assets are placed in service. Depreciation expense for the fiscal years ended June 30, 2024, 2023 and 2022 was $181.7 million, $154.2 million and $122.2 million, respectively. Leases . Under Accounting Standards Codification (“ASC”) 842, Leases, a contract is or contains a lease when we have the right to control the use of an identified asset for a period of time. We determine if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to, and the agreement creates enforceable rights and obligations. The commencement date of the lease is the date that the lessor makes an underlying asset available for our use. On the commencement date, leases are evaluated for classification and assets and liabilities are recognized based on the present value of lease payments over the lease term. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The right of use (“ROU”) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments and any lease incentives. Variable lease payments, consisting primarily of reimbursement of costs incurred by lessors for common area maintenance, real estate taxes and insurance, are not included in the lease liability and are recognized as they are incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate at lease commencement to measure ROU assets and lease liabilities. The incremental borrowing rate used by us is based on baseline rates and adjusted by the credit spreads commensurate with our secured borrowing rate, over a similar term. We used the incremental borrowing rate on June 30, 2019 for all leases that commenced on or prior to that date. Operating lease expense is generally recognized on a straight-line basis over the lease term. We have elected the practical expedient to account for the lease and non-lease components as a single lease component for the majority of our asset classes. For leases with a term of one year or less, we have elected not to record the ROU asset or liability. Goodwill, Purchased Intangible Assets and Impairment Assessment. Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. We assess goodwill for impairment annually during our third fiscal quarter or whenever events or changes in circumstances indicate the carrying value may not be fully recoverable. We have the option to perform a qualitative assessment prior to necessitating a quantitative impairment test. In the qualitative assessment, if we determine that it is more likely than not that the fair value of a reporting unit is less than the carrying value, a quantitative test is then performed, which involves comparing the estimated fair value of a reporting unit to its carrying value including goodwill. If goodwill is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value. Refer to Note 7 “Goodwill and Purchased Intangible Assets” for information related to determining the fair value of a reporting unit. Purchased intangible assets that are not considered to have an indefinite useful life are amortized over their estimated useful lives, which generally range from six months to nine years. The carrying values of our intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying value of an asset or asset group may not be recoverable. Impairment of Long-Lived Assets. Long-lived assets are tested for impairment whenever events or changes in circumstances indicate that their carrying amounts may not be recoverable. Events or changes in circumstances that could affect the likelihood that we will be required to recognize an impairment charge for the long-lived assets primarily include declines in our operating cash flows from the use of these assets. We determine whether long-lived assets are recoverable based on the forecasted undiscounted future cash flows that are expected to be generated by the lowest-level associated asset grouping. If the undiscounted cash flows used in the recoverability test are less than the long-lived assets’ carrying value, we recognize an impairment loss for the amount that the carrying value exceeds the fair value. We determine the fair value of long-lived assets using the income approach, primarily by applying the relief-from-royalty or multi-period excess-earnings methods, when deemed appropriate. Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash equivalents, short-term marketable securities, trade accounts receivable and derivative financial instruments used in hedging activities. We invest in a variety of financial instruments, such as, but not limited to, certificates of deposit, corporate debt and municipal securities, U.S. Treasury and Government agency securities, and equity securities and, by policy, we limit the amount of credit exposure with any one financial institution or commercial issuer. We have not experienced any material credit losses on our investments. A majority of our accounts receivable are derived from sales to large multinational semiconductor and electronics manufacturers located throughout the world, with a majority located in Asia. In recent years, our customer base has become increasingly concentrated due to corporate consolidations, acquisitions and business closures, and to the extent that these customers experience liquidity issues in the future, we may be required to reserve for potential credit losses with respect to trade receivables. We perform ongoing credit evaluations of our customers’ financial condition and generally require little to no collateral to secure accounts receivable. We maintain an allowance for potential credit losses based upon expected collectability risk of all accounts receivable. In addition, we may utilize letters of credit (“LC”) or non-recourse factoring to mitigate credit risk when considered appropriate. We are exposed to credit loss in the event of non-performance by counterparties on the foreign exchange contracts that we use in hedging activities and in certain factoring transactions. These counterparties are large international financial institutions, and, to date, no such counterparty has failed to meet its financial obligations to us under such contracts. The following customers each accounted for more than 10% of total revenues, primarily in the Semiconductor Process Control segment, for the indicated periods: Year Ended June 30, 2024 2023 2022 Taiwan Semiconductor Manufacturing Company Limited Taiwan Semiconductor Manufacturing Company Limited Taiwan Semiconductor Manufacturing Company Limited Samsung Electronics Co., Ltd. Samsung Electronics Co., Ltd. The following customers each accounted for more than 10% of net accounts receivable as of the dates indicated below: As of June 30, 2024 2023 Taiwan Semiconductor Manufacturing Company Limited Taiwan Semiconductor Manufacturing Company Limited Samsung Electronics Co., Ltd. Foreign Currency. The functional currencies of our foreign subsidiaries are primarily the local currencies, except as described below. Accordingly, all assets and liabilities of these foreign operations are translated to U.S. dollars at current period end exchange rates, and revenues and expenses are translated to U.S. dollars using average exchange rates in effect during the period. The gains and losses from foreign currency translation of these subsidiaries’ financial statements are recorded directly into a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income (loss).” Our manufacturing subsidiaries in Singapore, Israel, Germany, and the United Kingdom use the U.S. dollar as their functional currency. Accordingly, monetary assets and liabilities in non-functional currency of these subsidiaries are remeasured using exchange rates in effect at the end of the period. Revenues and costs in local currency are remeasured using average exchange rates for the period, except for costs related to those balance sheet items that are remeasured using historical exchange rates. The resulting remeasurement gains and losses are included in the Consolidated Statements of Operations as incurred. Derivative Financial Instruments. We use financial instruments, such as foreign exchange contracts including forward and options transactions, to hedge a portion of, but not all, existing and forecasted foreign currency denominated transactions. The purpose of our foreign exchange hedging program is to manage the effect of exchange rate fluctuations on certain foreign currency denominated revenues, costs and eventual cash flows. The effect of exchange rate changes on foreign exchange contracts is expected to offset the effect of exchange rate changes on the underlying hedged items. We also use forward contracts to hedge the risk associated with the variability of cash flows due to changes in the benchmark interest rate of the intended debt financing (“Rate Lock Agreements”). We believe these financial instruments do not subject us to speculative risk that would otherwise result from changes in currency exchange rates or interest rates. All of our derivative financial instruments are recorded at fair value based upon quoted market prices for comparable instruments adjusted for risk of counterparty non-performance. For derivative instruments designated and qualifying as cash flow hedges of forecasted foreign currency denominated transactions or debt financing, the effective portion of the gains or losses is reported in Accumulated other comprehensive income (loss) (“AOCI”) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We elected to include time value for the assessment of effectiveness on all forward transactions designated as cash flow hedges. The change in fair value of the derivative is recorded in AOCI until the hedged transaction is recognized in earnings. The assessment of effectiveness of options contracts designated as cash flow hedges excludes time value. The initial value of the component excluded from the assessment of effectiveness is recognized in earnings over the life of the derivative contract. Any differences between change in the fair value of the excluded components and the amounts recognized in earnings are recorded in AOCI. For foreign exchange contracts that are designated and qualify as a net investment hedge in a foreign operation and that meet the effectiveness requirements, the net gains or losses attributable to changes in spot exchange rates are recorded in cumulative translation within AOCI. The remainder of the change in value of such instruments is recorded in earnings using the mark-to-market approach. Recognition in earnings of amounts previously recorded in cumulative translation is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operations. For foreign exchange contracts that are not designated as hedges, gains and losses are recognized in Other expense (income), net. We use foreign exchange contracts to hedge certain foreign currency denominated assets or liabilities. The gains and losses on these derivative instruments are largely offset by the changes in the fair value of the assets or liabilities being hedged. Revenue Recognition. We primarily derive revenue from the sale of process control and process-enabling solutions for the semiconductor and related electronics industries, maintenance and support of all these products, installation and training services and the sale of spare parts. Our portfolio includes yield enhancement and production solutions for manufacturing wafers and reticles, ICs, packaging, PCBs and flat panel displays (“FPD”), as well as comprehensive support and services across our installed base. Our solutions are generally not sold with a right of return, nor have we experienced significant returns from or refunds to our customers. We account for a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Our revenues are measured based on consideration stipulated in the arrangement with each customer, net of any sales incentives and amounts collected on behalf of third parties, such as sales taxes. The revenues are recognized as separate performance obligations that are satisfied by transferring control of the product or service to the customer. Our arrangements with our customers include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. A product or service is considered distinct if it is separately identifiable from other deliverables in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The transaction consideration, including any sales incentives, is allocated between separate performance obligations of an arrangement based on the stand-alone selling price (“SSP”) for each distinct product or service. Management considers a variety of factors to determine the SSP, such as historical stand-alone sales of products and services, discounting strategies and other observable data. From time to time, our contracts are modified to account for additional, or to change existing, performance obligations. Our contract modifications are generally accounted for prospectively. Product Revenue We recognize revenue from product sales at a point in time when we have satisfied our performance obligation by transferring control of the product to the customer. We use judgment to evaluate whether control has transferred by considering several indicators, including whether: • We have a present right to payment; • The customer has legal title; • The customer has physical possession; • The customer has significant risk and rewards of ownership; and • The customer has accepted the product, or whether customer acceptance is considered a formality based on history of acceptance of similar products (for example, when the customer has previously accepted the same tool, with the same specifications, and when we can objectively demonstrate that the tool meets all of the required acceptance criteria, and when the installation of the system is deemed perfunctory). Not all of the indicators need to be met for us to conclude that control has transferred to the customer. In circumstances in which revenue is recognized prior to the product acceptance, the fair value of revenue associated with our performance obligations to install the product is deferred and recognized as revenue at a point in time, once installation is complete. We enter into volume purchase agreements with some of our customers. We adjust the transaction consideration for estimated credits and incentives earned by our customers. These credits are estimated based upon the forecasted and actual product sales for any given period and agreed incentive rate. The estimate is reviewed for material changes and updated at each reporting period. We offer perpetual and term licenses for software products. The primary difference between perpetual and term licenses is the duration over which the customer can benefit from the use of the software, while the functionality and the features of the software are the same. Software is generally bundled with post-contract customer support (“PCS”), which includes unspecified software updates that are made available throughout the entire term of the arrangement. Revenue from software licenses is recognized at a point in time, when the software is made available to the customer. Revenue from PCS is deferred at contract inception and recognized ratably over the service period, or as services are performed. Services Revenue The majority of product sales include a standard 12-month warranty that is not separately paid for by the customers. The customers may also purchase an extended warranty for periods beyond the initial period as part of the initial product sale. We have concluded that the standard 12-month warranty as well as any extended warranty periods included in the initial product sales are separate performance obligations for most of our products. The estimated fair value of warranty services is deferred and recognized ratably as revenue over the warranty period, as the customer simultaneously receives and consumes the benefits of warranty services provided by us. Additionally, we offer product maintenance and support services, which the customer may purchase separately from the standard and extended warranty offered as part of the initial product sale. Revenue from separately negotiated maintenance and support service contracts is also recognized over time based on the terms of the applicable service period. Revenue from services performed in the absence of a maintenance contract, including training revenue, is recognized when the related services are performed. We also sell spare parts, revenue from which is recognized when control over the spare parts is transferred to the customer. Significant Judgments Our contracts with our customers often include promises to transfer multiple products and services. Each product and service is generally capable of being distinct within the context of the contract and represents a separate performance obligation. Determining the SSP for each distinct performance obligation and allocation of consideration from an arrangement to the individual performance obligations and the appropriate timing of revenue recognition are significant judgments with respect to these arrangements. We typically estimate the SSP of products and services based on observable transactions when the products and services are sold on a stand-alone basis and those prices fall within a reasonable range. We typically have more than one SSP for individual products and services due to the stratification of these products by customers and circumstances. In these instances, we use information such as the size of the customer, geographic region, as well as customization of the products in determining the SSP. In instances where the SSP is not directly observable, we determine the SSP using information that includes market conditions, entity-specific factors, including discounting strategies, information about the customer or class of customer that is reasonably available and other observable inputs. While changes in the allocation of SSP between performance obligations will not affect the amount of total revenue recognized for a particular contract, any material changes could impact the timing of revenue recognition, which could have a material effect on our financial position and results of operations. Although our products are generally not sold with a right of return, we may provide other credits or sales incentives, which are accounted for either as variable consideration or material right, depending on the specific terms and conditions of the arrangement. These credits and incentives are estimated at contract inception and updated at the end of each reporting period if and when additional information becomes available. As outlined above, we use judgments to evaluate whether or not the customer has obtained control of the product and consider several indicators in evaluating whether or not control has transferred to the customer. Not all of the indicators need to be met for us to conclude that control has transferred to the customer. Contract Assets/Liabilities The timing of revenue recognition, billings and cash collections may result in accounts receivable, contract assets, and contract liabilities (deferred revenue) on our Consolidated Balance Sheets. A receivable is recorded in the period we deliver products or provide services when we have an unconditional right to payment. Contract assets primarily relate to the value of products and services transferred to the customer for which the right to payment is not just dependent on the passage of time. Contract assets are transferred to accounts receivable when rights to payment become unconditional. A contract liability is recognized when we receive payment or have an unconditional right to payment in advance of the satisfaction of performance. The contract liabilities represent (1) deferred product revenue related to the value of products that have been shipped and billed to customers and for which control has not been transferred to the customers, and (2) deferred service revenue, which is recorded when we receive consideration, or such consideration is unconditionally due, from a customer prior to transferring services to the customer under the terms of a contract. Deferred service revenue typically results from warranty services, and maintenance and other service contracts. Contract assets and liabilities related to rights and obligations in a contract are recorded net in the Consolidated Balance Sheets. Research and Development Costs. R&D costs are expensed as incurred. Shipping an

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Contract Balances The following table represents the opening and closing balances of accounts receivable, contract assets and contract liabilities for the indicated periods. As of As of As of (In thousands, except for percentages) June 30, 2024 June 30, 2023 June 30, 2022 Change in Fiscal 2024 Change in Fiscal 2023 Accounts receivable, net $ 1,833,041 $ 1,753,361 $ 1,811,877 $ 79,680 5 % $ (58,516) (3) % Contract assets $ 69,259 $ 117,137 $ 114,747 $ (47,878) (41) % $ 2,390 2 % Contract liabilities $ 1,782,242 $ 1,245,007 $ 1,007,324 $ 537,235 43 % $ 237,683 24 % Our payment terms and conditions vary by contract type, although terms generally include a requirement of payment of 70% to 90% of total contract consideration within 30 to 60 days of shipment, with the remainder payable within 30 days of acceptance. The change in contract assets during the fiscal year ended June 30, 2024 was mainly due to $104.1 million of contract assets reclassified to net accounts receivable as our right to consideration for these contract assets became unconditional, partially offset by $56.8 million of revenue recognized for which the payment is subject to conditions other than the passage of time. Contract assets are included in other current assets on our Consolidated Balance Sheets. The change in contract liabilities during the fiscal year ended June 30, 2024 was mainly due to the value of products and services billed to customers for which control of the products and services has not transferred to the customers, partially offset by the recognition in revenue of $963.5 million that was included in contract liabilities as of June 30, 2023. The change in contract liabilities during the fiscal year ended June 30, 2023 was mainly due to the value of products and services billed to customers for which control of the products and services has not transferred to the customers, partially offset by the recognition in revenue of $819.0 million that was included in contract liabilities as of June 30, 2022. Contract liabilities are included in current and non-current liabilities on our Consolidated Balance Sheet. Remaining Performance Obligations As of June 30, 2024, we had $9.83 billion of remaining performance obligations (“RPO”), which represents our obligation to deliver products and services, and primarily consists of sales orders where written customer requests have been received. This amount includes customer deposits of $745.7 million as disclosed in Note 4 “Financial Statement Components” and excludes contract liabilities of $1.78 billion as disclosed above. We expect to recognize approximately 59% to 64% of these performance obligations as revenue in the next 12 months, 29% to 34% in the subsequent 12 months and the remainder thereafter, but this estimate is subject to constant change. The timing of revenue recognition of our RPO is evaluated quarterly and is largely driven by multiple variables, many of which are beyond our control, such as: the readiness of customer fabs, end market needs for capacity, changes in the estimated versus actual start time of customers’ projects, timing of delivery and installation dates, supply chain constraints and changes in regulations. Our customers are currently purchasing equipment from us with lead times that are longer than our historical experience. As customers try to balance the evolution of their technological, production or market needs with the timing and content of orders placed with us, there is elevated risk of order modifications, pushouts or cancellations. In addition, in October 2022, the U.S. government issued regulations that imposed new export licensing requirements for certain U.S. semiconductor and high-performance computing technology (including wafer fab equipment), for the use of such technology for certain end uses in the People’s Republic of China (“China”), and for the provision of support by U.S. Persons to certain advanced IC fabs located in China. The regulations impose export license requirements effectively on all KLA products and services to customers located in China that fabricate certain advanced logic, NAND and DRAM ICs. KLA is also restricted from providing certain U.S. origin tools, software and technology to certain wafer fab equipment manufacturers located in China, absent an export license. In October 2023, the U.S. government issued additional regulations that went into effect in November 2023. These additional rules are designed to update export controls on advanced computing semiconductors and semiconductor manufacturing equipment, as well as items that support supercomputing applications and end-uses, to arms embargoed countries, including China. They adjust the parameters included in the existing regulations that determine whether an advanced computing chip is restricted and impose new measures to address risks of circumvention of the controls established in October 2022. The regulations are very complex and, in January 2024, KLA, among other companies, submitted comments to the government regarding these regulations. We are taking appropriate measures to comply with all government regulations, and will continue to apply for export licenses, when required, to avoid disruption to our customers’ operations. While some export licenses have been obtained by us or our customers, there can be no assurance that export licenses applied for by either us or our customers, now or in the future, will be granted. Practical expedients We apply the following practical expedients in accordance with ASC 606, Revenue from Contracts with Customers: • We account for shipping and handling costs as activities to fulfill the promise to transfer goods, instead of a promised service to our customer. • We have elected to not adjust the promised amount of consideration for the effects of a significant financing component as we expect, at contract inception, that the period between when we transfer a promised good or service to a customer and when the customer pays for that good or service will generally be one year or less. • We have elected to expense costs to obtain a contract as incurred because the expected amortization period is one year or less. Refer to Note 19 “Segment Reporting and Geographic Information” for information related to revenue by geographic region as well as significant product and service offerings.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	12 Months Ended

Fair Value Disclosures [Abstract]
FAIR VALUE MEASUREMENTS	FAIR VALUE MEASUREMENTS Our financial assets and liabilities are measured and recorded at fair value, except for our debt and certain equity investments in privately held companies. Equity investments without a readily available fair value are accounted for using the measurement alternative. The measurement alternative is calculated as cost minus impairment, if any, plus or minus changes resulting from observable price changes. See Note 8 “Debt” for disclosure of the fair value of our Senior Notes, as defined in that Note. Our non-financial assets, such as goodwill, intangible assets, and land, property and equipment, are assessed for impairment when an event or circumstance indicates that an other-than-temporary decline in value may have occurred. Fair Value of Financial Instruments. We have evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. The fair value of our cash equivalents, accounts receivable, accounts payable and other current assets and liabilities approximate their carrying amounts due to the relatively short maturity of these items. Fair Value Hierarchy. The authoritative guidance for fair value measurements establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2 Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities. Level 3 Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. There were no transfers between Level 1, Level 2 and Level 3 fair value measurements during the years ended June 30, 2024 and June 30, 2023. The types of instruments valued based on quoted market prices in active markets included money market funds, certain U.S. Treasury securities, U.S. Government agency securities and equity securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs included corporate debt securities, municipal securities and certain U.S. Treasury securities. The market inputs used to value these instruments generally consist of market yields, reported trades and broker/dealer quotes. Such instruments are generally classified within Level 2 of the fair value hierarchy. The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants generally are large financial institutions. Our foreign currency contracts’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy. The fair values of contingent consideration payable, the majority of which were recorded in connection with business combinations, were classified as Level 3 and estimated using significant inputs that were not observable in the market. See Note 6 “Business Combinations and Dispositions” for additional information. Financial assets (excluding cash held in operating accounts and time deposits) and liabilities measured at fair value on a recurring basis as of the date indicated below were presented on our Consolidated Balance Sheets as follows: As of June 30, 2024 (In thousands) Total Quoted Prices Significant Little or No Assets Cash equivalents: Corporate debt securities $ 2,312 $ — $ 2,312 $ — Money market funds and other 1,585,832 1,585,832 — — U.S. Treasury securities 35,158 — 35,158 — Marketable securities: Corporate debt securities 771,920 — 771,920 — Municipal securities 41,159 — 41,159 — U.S. Government agency securities 105,874 105,874 — — U.S. Treasury securities 716,148 476,230 239,918 — Equity securities 25,566 25,566 — — Total cash equivalents and marketable securities (1) 3,283,969 2,193,502 1,090,467 — Other current assets: Derivative assets 36,503 — 36,503 — Other non-current assets: EDSP 303,365 272,816 30,549 — Total financial assets (1) $ 3,623,837 $ 2,466,318 $ 1,157,519 $ — Liabilities Derivative liabilities $ (15,683) $ — $ (15,683) $ — Total financial liabilities $ (15,683) $ — $ (15,683) $ — __________________ (1) Excludes cash of $287.6 million held in operating accounts and time deposits of $932.4 million (of which $66.2 million were cash equivalents) as of June 30, 2024.

(2) Excludes equity marketable securities. Our investment portfolio includes both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. Most of our unrealized losses are due to changes in market interest rates, and bond yields. We believe that we have the ability to realize the full value of all these investments upon maturity. As of June 30, 2024, we had 409 investments in an unrealized loss position.

Goodwill and Intangible Assets Disclosure [Abstract]
GOODWILL AND PURCHASED INTANGIBLE ASSETS	GOODWILL AND PURCHASED INTANGIBLE ASSETS Goodwill Goodwill represents the excess of the purchase price over the fair value of the net tangible and identifiable intangible assets acquired in business combinations. As of June 30, 2024, we have three reportable segments, five operating segments and six reporting units. The following table presents the carrying value of goodwill and the movements by reporting unit during the fiscal years ended June 30, 2024 and 2023: (In thousands) Wafer Inspection and Patterning Global Service and Support ( “ GSS ” ) Specialty Semiconductor Process PCB and Display PCB Display Component Inspection Total Balances as of June 30, 2022 Goodwill $ 1,003,307 $ 25,908 $ 826,037 $ 985,441 $ — $ — $ 13,575 $ 2,854,268 Accumulated impairment losses (277,570) — (144,179) (112,470) — — — (534,219) 725,737 25,908 681,858 872,971 — — 13,575 $ 2,320,049 Activity for the year ended June 30, 2023 Acquired goodwill 6,776 — — — — — — 6,776 Goodwill disposal from sale of business (1) — — — (42,622) — — — (42,622) Goodwill adjustments (5,337) — — — — — — (5,337) Foreign currency adjustment (46) — — — — — — (46) Balances as of June 30, 2023 Goodwill 1,004,700 25,908 826,037 942,819 — — 13,575 2,813,039 Accumulated impairment losses (277,570) — (144,179) (112,470) — — — (534,219) 727,130 25,908 681,858 830,349 — — 13,575 2,278,820 Activity for the year ended June 30, 2024 Goodwill impairment — — — (192,600) — (70,474) (263,074) Reallocation due to change in reporting units — — — (637,749) 567,275 70,474 — Foreign currency adjustments (20) — — — — — — (20) Balances as of June 30, 2024 Goodwill 1,004,680 25,908 826,037 — 567,275 70,474 13,575 2,507,949 Accumulated impairment losses (277,570) — (144,179) — — (70,474) — (492,223) $ 727,110 $ 25,908 $ 681,858 $ — $ 567,275 $ — $ 13,575 $ 2,015,726 _________________ (1) Refer to the Business Dispositions section of Note 6 “Business Combinations and Dispositions” for more information on the sale of Orbograph. Goodwill is not subject to amortization but is tested for impairment annually during the third fiscal quarter, as well as whenever events or changes in circumstances indicate that the carrying value may not be recoverable. During the second quarter of fiscal 2024, we noted a significant deterioration of the long-term forecast for our PCB and manufacturing flat and flexible panel displays (“Display”) businesses, which are a part of our PCB and Display operating segment, as the company initiated its annual strategic planning process. The downward revision of financial outlook for the PCB and Display businesses triggered a goodwill impairment test. In addition, in the second quarter of fiscal 2024, we began to evaluate strategic options for our Display business. Effective from the second quarter of fiscal 2024, our PCB and Display operating segment is comprised of two reporting units, 1) PCB and 2) Display while, prior to the change, the PCB and Display operating segment represented a single reporting unit. As a result of our quantitative assessment, we recorded a total goodwill impairment charge of $192.6 million fo r the PCB and Display reporting unit in the quarter ended December 31, 2023. The goodwill balances of the new PCB and Display reporting units were determined based on their relative fair values. We assessed for impairment subsequent to the reporting unit change and noted no impairment. To determine the fair value of a reporting unit, we utilized income and market approaches and applied a weighting of 75 percent and 25 percent , respectively. The income approach is estimated through discounted cash flow analysis. The estimated fair value of this reporting unit was computed by adding the present value of the estimated annual discounted cash flows over a discrete projection period to the residual value of the business at the end of the projection period. This valuation technique requires us to use significant estimates and assumptions, including long-term growth rates, discount rates and other inputs. The estimated growth rates for the projection period are based on our internal forecasts of anticipated future performance of the business. The residual value is estimated using a perpetual nominal growth rate, which is based on projected long-range inflation and long-term industry projections. The discount rates are calculated as the weighted average cost of capital of comparable peer companies, adjusted for company-specific risk. The market approach estimates the fair value of the reporting unit by utilizing the market comparable method, which uses revenue and earnings multiples from comparable companies. We performed the required annual goodwill impairment testing for all reporting units as of February 29, 2024, and concluded that goodwill was not impaired, except for the Display reporting unit. As a result of this qualitative assessment, we determined that it was not necessary to perform a quantitative assessment for the reporting units subject to testing other than Display. In March 2024, we made the decision to exit the Display business by announcing the end of manufacturing of most Display products by December 31, 2024, but we will continue to provide services to the installed base of Display products for existing customers. The exit of the business does not qualify as a discontinued operation under the relevant accounting guidance, but the decision triggered a quantitative impairment assessment for the Display reporting unit, which resulted in a total goodwill impairment charge of $70.5 million in the quarter ended March 31, 2024. To determine the fair value of the reporting unit, we utilized an income approach estimated through a discounted cash flow analysis, by adding the present value of the estimated annual discounted cash flows over a discrete projection period. This valuation technique requires us to use significant estimates and assumptions, including discount rates and internal forecasts of the anticipated future performance of the business. The discount rates are calculated as the weighted average cost of capital of comparable peer companies, adjusted for company-specific risk. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future. We performed the required annual goodwill impairment test as of February 28, 2023 and concluded that goodwill was not impaired. As a result of our qualitative assessments, we determined that it was not necessary to perform a quantitative assessment at that time. There have been no significant events or circumstances affecting the valuation of goodwill subsequent to the assessment performed in the third quarter of the fiscal year ended June 30, 2024. The next annual assessment of goodwill by reporting unit is scheduled to be performed in the third quarter of the fiscal year ending June 30, 2025.

In connection with the evaluation of the goodwill impairment in the PCB and Display reporting unit during the second quarter of fiscal 2024, due to the downward revision of financial outlook for the businesses as noted above, the Company assessed tangible and intangible assets for impairment prior to performing the goodwill impairment test. The Company first performed a recoverability test for each asset group identified in the PCB and Display operating seg ment by comparing projected undiscounted cash flows from the use and eventual disposition of each asset group to its carrying value. This test indicated that the undiscounted cash flows were not sufficient to recover the carrying value of the asset groups. We then compared the carrying value of the individual long-lived assets within those asset groups against their fair value in order to measure the impairment loss. As a result of this assessment, we recorded a total purchased intangible asset impairment charge $26.4 million . No impairment was identified for other long-lived assets in the three months ended December 31, 2023. The total impairment charges for goodwill and purchased intangible assets of $219.0 million during the three months ended December 31, 2023, as well as the goodwill impairment charge of $70.5 million in the three months ended March 31, 2024, were recognized as separate charges and included in income (loss) from operations. As of June 30, 2024 and 2023, there were no impairment indicators for purchased intangible assets.

The net proceeds will be used for general corporate purposes, including repayment of outstanding indebtedness at or prior to maturity. In June 2022, we issued $3.00 billion aggregate principal amount of senior, unsecured notes (the “2022 Senior Notes”) as follows: $1.00 billion of 4.650% senior, unsecured notes due July 15, 2032; $1.20 billion of 4.950% senior, unsecured notes due July 15, 2052; and $800.0 million of 5.250% senior, unsecured notes due July 15, 2062. A portion of the net proceeds of the 2022 Senior Notes was used to complete a tender offer in July 2022 for $500.0 million of our 2014 Senior Notes due 2024 including associated redemption premiums, accrued interest and other fees and expenses. The redemption resulted in a pre-tax net loss on extinguishment of debt of $13.3 million for the fiscal year ended June 30, 2023. The remainder of the net proceeds was used for share repurchases and for general corporate purposes. In February 2020, March 2019 and November 2014, we issued $750.0 million, $1.20 billion and $2.50 billion, respectively (the “2020 Senior Notes,” “2019 Senior Notes” and “2014 Senior Notes,” respectively, and, collectively with the 2024 and 2022 Senior Notes, the “Senior Notes”) aggregate principal amount of senior, unsecured notes. In July 2022, February 2020, October 2019 and November 2017, we repaid $500.0 million, $500.0 million, $250.0 million and $250.0 million of the Senior Notes, respectively. The original discounts on the Senior Notes are being amortized over the life of the debt. Interest is payable as follows: semi-annually on February 1 and August 1 of each year for the 2024 Senior Notes; semi-annually on January 15 and July 15 of each year for the 2022 Senior Notes; semi-annually on March 1 and September 1 of each year for the 2020 Senior Notes; semi-annually on March 15 and September 15 of each year for the 2019 Senior Notes; and semi-annually on May 1 and November 1 of each year for the 2014 Senior Notes. The relevant indentures for the Senior Notes (collectively, the “Indenture”) include covenants that limit our ability to grant liens on our facilities and enter into sale and leaseback transactions. In certain circumstances involving a change of control followed by a downgrade of the rating of a series of Senior Notes by at least two of Moody’s Investors Service, S&P Global Ratings and Fitch Inc., unless we have exercised our rights to redeem the Senior Notes of such series, we will be required to make an offer to repurchase all or, at the holder’s option, any part, of each holder’s Senior Notes of that series pursuant to the offer described below (the “Change of Control Offer”). In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of Senior Notes repurchased plus accrued and unpaid interest, if any, on the Senior Notes repurchased, up to, but not including, the date of repurchase. The fair value of the Senior Notes as of June 30, 2024 and 2023 was $6.26 billion and $5.69 billion, respectively. While the Senior Notes are recorded at cost, the fair value of the long-term debt was determined based on quoted prices in markets that are not active; accordingly, the long-term debt is categorized as Level 2 for purposes of the fair value measurement hierarchy. As of June 30, 2024, we were in compliance with all of our covenants under the Indenture associated with the Senior Notes. Revolving Credit Facility: We have in place a Credit Agreement (“Credit Agreement”) for an unsecured Revolving Credit Facility (“Revolving Credit Facility”) having a maturity date of June 8, 2027 that allows us to borrow up to $1.50 billion. Subject to the terms of the Credit Agreement, the Revolving Credit Facility may be increased by an amount up to $250.0 million in the aggregate. As of June 30, 2024 and 2023, there were no borrowings under the Revolving Credit Facility. We may borrow, repay and reborrow funds under the Revolving Credit Facility until the maturity date, at which time may exercise two one-year extension options with the consent of the lenders. We may prepay outstanding borrowings under the Revolving Credit Facility at any time without a prepayment penalty. Borrowings under the Revolving Credit Facility can be made as Term Secured Overnight Financing (“SOFR”) Loans or Alternate Base Rate (“ABR”) Loans, at the Company’s option. In the event that Term SOFR is unavailable, any Term SOFR elections will be converted to Daily Simple SOFR, as long as it is available. Each Term SOFR Loan will bear interest at a rate per annum equal to the applicable Adjusted Term SOFR rate, which is equal to the applicable Term SOFR rate plus 10 bps that shall not be less than zero, plus a spread ranging from 75 bps to 125 bps, as determined by the Company’s credit ratings at the time. Each ABR Loan will bear interest at a rate per annum equal to the ABR plus a spread ranging from 0 bps to 25 bps, as determined by the Company’s credit ratings at the time. We are also obligated to pay an annual commitment fee on the daily undrawn balance of the Revolving Credit Facility, which ranges from 4.5 bps to 12.5 bps, subject to an adjustment in conjunction with changes to our credit rating. The applicable interest rates and commitment fees are also subject to adjustment based on the Company’s performance against certain environmental sustainability key performance indicators related to greenhouse gas emissions and renewable electricity usage. Our performance against these key performance indicators in calendar year 2022 resulted in reductions to the fees associated with our Revolving Credit Facility. As of June 30, 2024, we elected to pay interest on borrowings under the Revolving Credit Facility at the applicable Adjusted Term SOFR plus a spread of 85 bps and the applicable commitment fee on the daily undrawn balance of the Revolving Credit Facility was 6 bps. Under the Credit Agreement, the maximum leverage ratio as described in the Credit Agreement, on a quarterly basis, is 3.50 to 1.00, covering the trailing four consecutive fiscal quarters for each fiscal quarter, which may be increased to 4.00 to 1.00 for a period of time in connection with a material acquisition or a series of material acquisitions. As of June 30, 2024, our maximum allowed leverage ratio was 3.50 to 1.00. We were in compliance with all covenants under the Credit Agreement as of June 30, 2024.

Leases [Abstract]
LEASES	LEASES We have operating leases for facilities, vehicles and other equipment. Our facility leases are primarily used for administrative functions, R&D, manufacturing, and storage and distribution. Our finance leases are not material. Our existing leases do not contain significant restrictive provisions or residual value guarantees; however, certain leases contain provisions for the payment of maintenance, real estate taxes or insurance costs by us. Our leases have remaining lease terms ranging from less than one year to 28 years, including periods covered by options to extend the lease when it is reasonably certain that the option will be exercised. Lease expense was $54.6 million, $41.8 million and $36.6 million for the fiscal years ended June 30, 2024, 2023 and 2022, respectively. Expense related to short-term leases, which are not recorded on the Consolidated Balance Sheets, was not material for the fiscal years ended June 30, 2024 and 2023. As of both June 30, 2024 and 2023, the weighted-average remaining lease term was 6.7 years, and the weighted-average discount rate was 4.30% and 3.36%, as of June 30, 2024 and 2023, respectively. Supplemental cash flow information related to leases was as follows: Year Ended June 30, (In thousands) 2024 2023 Operating cash outflows from operating leases $ 41,405 $ 47,294 ROU assets obtained in exchange for new operating lease liabilities $ 62,505 $ 115,377 Maturities of lease liabilities as of June 30, 2024 were as follows: Fiscal Year Ending June 30: Amount 2025 $ 43,565 2026 38,395 2027 30,962 2028 21,694 2029 18,918 2030 and thereafter 70,637 Total lease payments 224,171 Less imputed interest (34,663) Total $ 189,508 As of June 30, 2024, we did not have any material leases that had not yet commenced.

Share-Based Payment Arrangement [Abstract]
EQUITY, LONG-TERM INCENTIVE COMPENSATION PLANS AND NON-CONTROLLING INTEREST	EQUITY, LONG-TERM INCENTIVE COMPENSATION PLANS AND NON-CONTROLLING INTEREST Equity Incentive Program On August 3, 2023, our Board of Directors adopted the KLA Corporation 2023 Incentive Award Plan (the “2023 Plan”), which replaced our 2004 Equity Incentive Plan (the “2004 Plan”) for grants of equity awards occurring on or after November 1, 2023. The new plan was approved by our stockholders at the annual meeting of stockholders held on November 1, 2023. As of June 30, 2024, we were able to issue new equity incentive awards, such as RSUs and stock options, to our employees, consultants and members of our Board of Directors under our 2023 Plan, with 10.2 million shares available for issuance. Any 2004 Plan and 2023 Plan awards of RSUs, performance shares, performance units or deferred stock units are counted against the total number of shares issuable under the 2023 Plan share reserve, or previously under the 2004 Plan reserve, as two shares for every one share subject thereto. In addition, the plan administrator has the ability to grant “dividend equivalent” rights in connection with awards of RSUs, performance shares, performance units and deferred stock units before they are fully vested. The plan administrator, at its discretion, may grant a right to receive dividends on the aforementioned awards, which may be settled in cash or our stock subject to meeting the vesting requirement of the underlying awards. All grants during the fiscal years ended June 30, 2024, 2023 and 2022 included dividend equivalent rights. Assumed Equity Plans As of the Orbotech Ltd. (“Orbotech”) Acquisition on February 20, 2019 (“Acquisition Date”), we assumed outstanding equity incentive awards under Orbotech equity incentive plans (the “Assumed Equity Plans”). The awards under the Assumed Equity Plans, previously issued in the form of stock options and RSUs, were generally settled as follows: a) Each award of Orbotech’s stock options and RSUs that was outstanding and vested immediately prior to the Acquisition Date (collectively, the “Vested Equity Awards”) was canceled and terminated and converted into the right to receive the purchase consideration in respect of such Vested Equity Awards as of the Acquisition Date and, in the case of stock options, less the exercise price. b) Each award of Orbotech’s stock options and RSUs that was outstanding and unvested immediately prior to the Acquisition Date was assumed by us (each, an “Assumed Option” and “Assumed RSU,” and collectively the “Assumed Equity Awards”) and converted to stock options and RSUs exercisable for the number of shares of our common stock based on the exchange ratio defined in the acquisition agreement. The Assumed Equity Awards generally retain all of the rights, terms and conditions of the respective plans under which they were originally granted, including the same service-based vesting schedule, applicable thereto. As of the Acquisition Date, the estimated fair value of the Assumed Equity Awards was $55.0 million, of which $13.3 million was recognized as goodwill and the balance of $41.7 million was recognized as stock-based compensation (“SBC”) expense over the remaining service period of the Assumed Equity Awards. The fair value of the Assumed Equity Awards for services rendered through the Acquisition Date was recognized as a component of the merger consideration, with the remaining fair value related to the post-combination services being recorded as SBC over the remaining vesting period. At the Acquisition Date, a total of 14,558 and 518,971 shares of our common stock underlay the Assumed Options and RSUs, respectively, and had an estimated weighted-average fair value of $53.3 and $104.5 per share, respectively. All Assumed Options were fully exercised as of June 30, 2020 and all Assumed RSUs were fully vested as of June 30, 2023. Equity Incentive Plans - General Information The following table summarizes the combined activity under our equity incentive plans: (In thousands) Available For Grant (1)(4) Balances as of June 30, 2021 10,253 RSUs granted (2) (1,152) RSUs granted adjustment (3) 39 RSUs canceled 102 Balances as of June 30, 2022 9,242 RSUs granted (2) (1,601) RSUs canceled 120 Balances as of June 30, 2023 7,761 Plan shares increased 3,250 RSUs granted (2) (849) RSUs canceled 78 Balances as of June 30, 2024 10,240 __________________ (1) The number of RSUs reflects the application of the award multiplier of 2.0x as described above. (2) Includes RSUs granted to senior management with performance-based vesting criteria (in addition to service-based vesting criteria for any of such RSUs that are deemed to have been earned) (“performance-based RSU”). As of June 30, 2024, it had not yet been determined the extent to which (if at all) the performance-based vesting criteria had been satisfied. Therefore, this line item includes all such performance-based RSUs granted during the fiscal year, reported at the maximum possible number of shares that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum levels and all applicable service-based criteria are fully satisfied (0.2 million shares, 0.6 million shares and 0.2 million shares for the fiscal years ended June 30, 2024, 2023 and 2022, respectively, reflecting the application of the 2.0x multiplier described above). (3) Represents the portion of RSUs granted with performance-based vesting criteria and reported at the actual number of shares issued upon achievement of the performance vesting criteria during the fiscal years ended June 30, 2024, 2023, and 2022. (4) No additional stock options, RSUs or other awards will be granted under the Assumed Equity Plans. The fair value of stock-based awards is measured at the grant date and is recognized as an expense over the employee’s requisite service period. The fair value for RSUs granted with “dividend equivalent” rights is determined using the closing price of our common stock on the grant date. The fair value for market-based RSUs is estimated on the grant date using a Monte Carlo simulation model with the following assumptions: expected volatilities ranging from 27.8% to 28.1%, based on a combination of implied volatility from traded options on our common stock and the historical volatility of our common stock; dividend yield ranging from 2.4% to 2.5%, based on our current expectations for our anticipated dividend policy; risk-free interest rate ranging from 2.3% to 2.4%, based on the implied yield available on U.S. Treasury zero-coupon issues with terms equal to the contractual terms of each tranche; and an expected term that takes into consideration the vesting term and the contractual term of the market-based award. The awards are amortized over service periods of three four The following table shows SBC expense for the indicated periods: Year Ended June 30, (In thousands) 2024 2023 2022 SBC expense by: Costs of revenues $ 35,942 $ 29,101 $ 21,108 R&D 60,124 44,702 27,618 SG&A 116,629 97,621 78,192 Total SBC expense $ 212,695 $ 171,424 $ 126,918 SBC capitalized as inventory as of June 30, 2024 and 2023 was $21.5 million and $16.7 million, respectively. Restricted Stock Units The following table shows the activity and weighted-average grant date fair value for RSUs during the fiscal year ended June 30, 2024: Shares (In thousands) (1) Weighted-Average Outstanding RSUs as of June 30, 2023 (2) 1,715 $ 312.40 Granted (2) 424 $ 584.49 Vested and released (633) $ 229.02 Forfeited (39) $ 366.93 Outstanding RSUs as of June 30, 2024 (2) 1,467 $ 424.66 __________________ (1) Share numbers reflect actual shares subject to awarded RSUs. Under the terms of the 2004 Plan for grants prior to November 1, 2023 or the terms of the 2023 Plan for grants on or after November 1, 2023, the number of shares subject to each award reflected in this number is multiplied by 2.0x to calculate the impact of the award on the share reserve under the respective plan. (2) Includes performance-based RSUs. As of June 30, 2024, it had not yet been determined the extent to which (if at all) the performance-based criteria had been satisfied. Therefore, this line item includes all such RSUs, reported at the maximum possible number of shares (i.e., 0.1 million shares for the fiscal year ended June 30, 2024) that may ultimately be issuable if all applicable performance-based criteria are achieved at their maximum. The RSUs granted by us generally vest (a) with respect to awards with only service-based vesting criteria, over periods ranging from two three The following table shows the weighted-average grant date fair value per unit for the RSUs granted, aggregate grant date fair value of RSUs vested, and tax benefits realized by us in connection with vested and released RSUs for the indicated periods: (In thousands, except for weighted-average grant date fair value) Year Ended June 30, 2024 2023 2022 Weighted-average grant date fair value per unit $ 584.49 $ 385.98 $ 353.27 Grant date fair value of vested RSUs $ 144,888 $ 107,217 $ 74,794 Tax benefits realized by us in connection with vested and released RSUs $ 47,315 $ 25,989 $ 23,634 As of June 30, 2024, the unrecognized SBC expense balance related to RSUs was $428.2 million, excluding the impact of estimated forfeitures, and will be recognized over a weighted-average remaining contractual term and an estimated weighted-average amortization period of 1.5 years. The intrinsic value of outstanding RSUs as of June 30, 2024 was $1.21 billion. Cash LTI Compensation As part of our employee compensation program, we issue Cash LTI awards to many of our employees. Executives and non-employee members of the Board of Directors do not participate in the Cash LTI Plan. During the fiscal years ended June 30, 2024 and 2023, we approved Cash LTI awards of $51.4 million and $67.1 million, respectively. Cash LTI awards issued to employees under the Cash LTI Plan will vest in three or four equal installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each anniversary of the grant date over a three Employee Stock Purchase Plan Our ESPP provides that eligible employees may contribute up to 15% of their eligible earnings toward the semi-annual purchase of our common stock. The ESPP is qualified under Section 423 of the Internal Revenue Code. The employee’s purchase price is derived from a formula based on the closing price of the common stock on the first day of the offering period versus the closing price on the date of purchase (or, if not a trading day, on the immediately preceding trading day). The offering period (or length of the look-back period) under the ESPP has a duration of six months, and the purchase price with respect to each offering period beginning on or after such date is, until otherwise amended, equal to 85% of the lesser of (i) the fair market value of our common stock at the commencement of the applicable six-month offering period or (ii) the fair market value of our common stock on the purchase date. We estimate the fair value of purchase rights under the ESPP using a Black-Scholes model. The fair value of each purchase right under the ESPP was estimated on the date of grant using the Black-Scholes model and the straight-line attribution approach with the following weighted-average assumptions: Year Ended June 30, 2024 2023 2022 Stock purchase plan: Expected stock price volatility 32.2 % 42.7 % 38.2 % Risk-free interest rate 5.3 % 2.5 % 0.1 % Dividend yield 1.1 % 1.6 % 1.2 % Expected life (in years) 0.50 0.50 0.50 The following table shows total cash received from employees for the issuance of shares under the ESPP, the number of shares purchased by employees through the ESPP, the tax benefits realized by us in connection with the disqualifying dispositions of shares purchased under the ESPP and the weighted-average fair value per share for the indicated periods: (In thousands, except for weighted-average fair value per share) Year Ended June 30, 2024 2023 2022 Total cash received from employees for the issuance of shares under the ESPP $ 144,934 $ 124,731 $ 113,015 Number of shares purchased by employees through the ESPP 320 418 419 Tax benefits realized by us in connection with the disqualifying dispositions of shares purchased under the ESPP $ 2,623 $ 1,916 $ 1,853 Weighted-average fair value per share based on Black-Scholes model $ 125.04 $ 89.52 $ 94.35 The ESPP shares are replenished annually on the first day of each fiscal year by virtue of an evergreen provision. The provision allows for share replenishment equal to the lesser of 2.0 million shares or the number of shares that we estimate will be required to be issued under the ESPP during the forthcoming fiscal year. As of June 30, 2024, a total of 2.3 million shares were reserved and available for issuance under the ESPP. Quarterly cash dividends On May 31, 2024, we paid a quarterly cash dividend of $1.45 per share on the outstanding shares of our common stock to stockholders of record as of the close of business on May 15, 2024. The total amount of regular quarterly cash dividends and dividend equivalents paid during the fiscal years ended June 30, 2024 and 2023 was $773.0 million and $732.6 million, respectively. The amount of accrued dividend equivalents payable related to unvested RSUs with dividend equivalent rights was $11.8 million and $12.2 million as of June 30, 2024 and 2023, respectively. These amounts will be paid upon vesting of the underlying RSUs. Refer to Note 21 “Subsequent Events” to the Consolidated Financial Statements for additional information regarding the declaration of our quarterly cash dividend announced subsequent to June 30, 2024. Non-controlling Interests As of June 30, 2022, we owned approximately 94% of the outstanding equity interest of Orbograph, which was a non-core business engaged in the development and marketing of character recognition solutions to banks, financial and other payment processing institutions and healthcare providers. On August 11, 2022, we sold our interest in Orbograph; for further details, refer to Note 6 “Business Combinations and Dispositions” to our Consolidated Financial Statements.

STOCK REPURCHASE PROGRAM

STOCK REPURCHASE PROGRAM	12 Months Ended

Equity [Abstract]
STOCK REPURCAHSE PROGRAM	STOCK REPURCHASE PROGRAM Our Board of Directors has authorized a program that permits us to repurchase our common stock, including increases in the authorized repurchase amount of $2.00 billion in the first quarter of fiscal 2022, $6.00 billion in the fourth quarter of fiscal 2022, and $2.00 billion in the first quarter of fiscal 2024. The stock repurchase program has no expiration date and may be suspended at any time. The intent of the program is, in part, to mitigate the potential dilutive impact related to our equity incentive plans and shares issued in connection with our ESPP as well as to return excess cash to our stockholders. Any and all share repurchase transactions are subject to market conditions and applicable legal requirements. On June 23, 2022, the Company executed accelerated share repurchase agreements (“ASR Agreements”) with two financial institutions to repurchase shares of our common stock in exchange for an upfront payment of $3.00 billion. The Company received initial deliveries totaling approximately 6.5 million shares of common stock in the fourth quarter of fiscal 2022, which represented 70% of the prepayment amount at the then prevailing market price of the Company’s shares of common stock. The initial shares delivered were retired immediately upon settlement and treated as repurchases of the Company’s common stock for purposes of earnings per share calculations. The total number of shares received under the ASR Agreements was based on the volume-weighted average price of the Company’s common stock during the term of the ASR Agreements, less an agreed-upon discount. Final settlement of the ASR Agreements occurred during the three months ended December 31, 2022, resulting in the delivery of 2.4 million additional shares, which yielded an average share price of $333.88 for the entire transaction. Under the authoritative guidance, share repurchases are recognized as a reduction to retained earnings to the extent available, with any excess recognized as a reduction of capital in excess of par value. In addition, as explained further in Note 14 “Income Taxes,” the Inflation Reduction Act of 2022 (“IRA”) introduced a 1% excise tax imposed on certain stock repurchases by publicly traded companies made after December 31, 2022. The excise tax is recorded as part of the cost basis of treasury stock repurchased after December 31, 2022 and, as such, is included in stockholders’ equity. As of June 30, 2024, an aggregate of approximately $2.18 billion was available for repurchase under our stock repurchase program. Share repurchase transactions for the indicated periods (based on the trade date of the applicable repurchase), with fiscal 2022 excluding the $0.90 billion portion of the ASR upfront payment that was recorded as an unsettled forward contract in fiscal 2022, were as follows: (In thousands) Year Ended June 30, 2024 2023 2022 Number of shares of common stock repurchased 3,032 5,844 11,768 Total cost of repurchases $ 1,742,501 $ 1,329,714 $ 3,962,267

NET INCOME PER SHARE

NET INCOME PER SHARE	12 Months Ended

Earnings Per Share [Abstract]
NET INCOME PER SHARE	NET INCOME PER SHARE Basic net income per share is calculated by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share is calculated by using the weighted-average number of common shares outstanding during the period, increased to include the number of additional shares of common stock that would have been outstanding if the shares of common stock underlying our outstanding dilutive RSUs had been issued. The dilutive effect of outstanding RSUs is reflected in diluted net income per share by application of the treasury stock method. In addition, the shares delivered under the ASR Agreements discussed in Note 11 “Stock Repurchase Program” in the fourth quarter of fiscal 2022 and second quarter of fiscal 2023 resulted in a reduction of outstanding shares used to determine our weighted-average common shares outstanding for purposes of calculating basic and diluted earnings per share for those respective fiscal years.

Retirement Benefits [Abstract]
EMPLOYEE BENEFIT PLANS	EMPLOYEE BENEFIT PLANS We have a profit sharing program for eligible employees, which distributes a percentage of our pre-tax profits on a quarterly basis. In addition, we have an employee savings plan that qualifies as a deferred salary arrangement under Section 401(k) of the Internal Revenue Code. Since January 1, 2019, the employer match is the greater of 50% of the first $8,000 of an eligible employee’s contributions or 50% of the first 5% of eligible compensation contributed plus 25% of the next 5% of compensation contributed. The total expenses under the profit sharing and 401(k) programs amounted to $39.4 million, $37.3 million, and $33.3 million in the fiscal years ended June 30, 2024, 2023 and 2022, respectively. We have no defined benefit plans in the U.S. In addition to the profit sharing plan and the U.S. 401(k), several of our foreign subsidiaries have retirement plans for their full-time employees, several of which are defined benefit plans. Consistent with the requirements of local law, our deposited funds for certain of these plans are held with insurance companies, with third-party trustees or in government-managed accounts. The assumptions used in calculating the obligation for the foreign plans depend on the local economic environment. We apply authoritative guidance that requires an employer to recognize the funded status of each of our defined benefit pension and post-retirement benefit plans as a net asset or liability on its balance sheets. Additionally, the authoritative guidance requires an employer to measure the funded status of each of its plans as of the date of its year-end statement of financial position. The benefit obligations and related assets under our plans have been measured as of June 30, 2024 and 2023. Summary data relating to our foreign defined benefit pension plans, including key weighted-average assumptions used, is provided in the following tables: Year Ended June 30, (In thousands) 2024 2023 Change in projected benefit obligation: Projected benefit obligation as of the beginning of the fiscal year $ 113,136 $ 124,585 Service cost 4,494 3,807 Interest cost 2,177 1,689 Contributions by plan participants 65 70 Actuarial gain (2,341) (7,686) Benefit payments (4,752) (4,837) Plan amendment impact — 191 Settlements impact (1,433) (931) Foreign currency exchange rate changes and other, net (6,101) (3,752) Projected benefit obligation as of the end of the fiscal year $ 105,245 $ 113,136 Year Ended June 30, (In thousands) 2024 2023 Change in fair value of plan assets: Fair value of plan assets as of the beginning of the fiscal year $ 45,930 $ 43,593 Employer contributions 9,514 8,396 Foreign currency exchange rate changes and other, net (1,863) (827) Settlements impact (1,433) (931) Actual return on plan assets 1,542 (1,064) Benefit and expense payments (3,295) (3,237) Fair value of plan assets as of the end of the fiscal year $ 50,395 $ 45,930 As of June 30, (In thousands) 2024 2023 Underfunded status $ 54,850 $ 67,206 As of June 30, (In thousands) 2024 2023 Plans with accumulated benefit obligations in excess of plan assets: Accumulated benefit obligation $ 67,349 $ 65,992 Projected benefit obligation $ 105,245 $ 108,084 Plan assets at fair value $ 50,395 $ 40,648 Year Ended June 30, 2024 2023 2022 Weighted-average assumptions (1) : Discount rate 1.5% - 3.9% 0.9% - 3.0% 0.9% - 3.0% Expected rate of return on assets 1.5% - 3.9% 0.9% - 2.6% 0.9% - 3.0% Rate of compensation increases 3.0% - 5.0% 3.0% - 5.0% 2.3% - 5.0% __________________ (1) Represents the weighted-average assumptions used to determine the benefit obligation. The assumptions for expected rate of return on assets were developed by considering the historical returns and expectations of future returns relevant to the country in which each plan is in effect and the investments applicable to the corresponding plan. The discount rate for each plan was derived by reference to appropriate benchmark yields on high-quality corporate bonds, allowing for the approximate duration of both plan obligations and the relevant benchmark index. The following table presents losses recognized in AOCI before tax related to our foreign defined benefit pension plans: As of June 30, (In thousands) 2024 2023 Unrecognized prior service cost $ 10,360 $ 10,733 Unrealized net loss 9,662 12,932 Amount of losses recognized $ 20,022 $ 23,665 The components of our net periodic cost relating to our foreign subsidiaries’ defined benefit pension plans are as follows: Year Ended June 30, (In thousands) 2024 2023 2022 Components of net periodic pension cost: Service cost (1) $ 4,494 $ 3,807 $ 5,054 Interest cost 2,177 1,678 1,003 Return on plan assets (961) (426) (528) Amortization of prior service cost 853 873 671 Amortization of net loss 221 698 1,406 Loss due to settlement/curtailment 68 85 38 Foreign currency exchange rate changes — — (19) Net periodic pension cost $ 6,852 $ 6,715 $ 7,625 __________________ (1) Service cost is reported in Cost of revenues, R&D and SG&A expenses Other expense (income) Fair Value of Plan Assets Fair value is 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. The three levels of inputs used to measure fair value of plan assets are described in Note 3 “Fair Value Measurements.” The foreign plans’ investments are managed by third-party trustees consistent with the regulations or market practice of the country where the assets are invested. We are not actively involved in the investment strategy, nor do we have control over the target allocation of these investments. These investments made up 100% of total foreign plan assets in the fiscal years ended June 30, 2024 and 2023. The expected aggregate employer contribution for the foreign plans during the fiscal year ending June 30, 2025 is $2.6 million. The total benefits to be paid from the foreign pension plans are not expected to exceed $6.9 million in any year through the fiscal year ending June 30, 2034. Foreign plan assets measured at fair value on a recurring basis consisted of the following investment categories as of June 30, 2024 and 2023, respectively: As of June 30, 2024 (In thousands) Total Quoted Prices in Significant Other Cash and cash equivalents $ 35,811 $ 35,811 $ — Bonds, equity securities and other investments 14,584 — 14,584 Total assets measured at fair value $ 50,395 $ 35,811 $ 14,584 As of June 30, 2023 (In thousands) Total Quoted Prices in Significant Other Cash and cash equivalents $ 32,114 $ 32,114 $ — Bonds, equity securities and other investments 13,816 — 13,816 Total assets measured at fair value $ 45,930 $ 32,114 $ 13,816 Concentration of Risk We manage a variety of risks, including market, credit and liquidity risks, across our plan assets through our investment managers. We define a concentration of risk as an undiversified exposure to one of the above-mentioned risks that increases the exposure of the loss of plan assets unnecessarily. We monitor exposure to such risks in the foreign plans by monitoring the magnitude of the risk in each plan and diversifying our exposure to such risks across a variety of instruments, markets and counterparties. As of June 30, 2024, we did not have concentrations of plan asset investment risk in any single entity, manager, counterparty, sector, industry or country.

This provision was first effective for the Company in the year ending June 30, 2023. As of June 30, 2024, we had U.S. federal, state and foreign net operating loss (“NOL”) carry-forwards of $6.5 million, $11.8 million and $221.5 million, respectively. We also had foreign capital loss carry-forwards of $8.6 million as of June 30, 2024. The U.S. federal NOL carry-forwards will expire at various dates beginning in 2025 through 2042. The utilization of NOLs created by acquired companies is subject to annual limitations under Section 382 of the Internal Revenue Code. However, it is not expected that such annual limitation will significantly impair the realization of these NOLs. The state NOLs will expire at various dates beginning in 2028 through 2036. Foreign NOLs and capital loss carry-forwards will be carried forward indefinitely. State credits of $366.6 million will also be carried forward indefinitely. The net deferred tax asset valuation allowance was $289.5 million and $259.2 million as of June 30, 2024 and 2023, respectively. The change was primarily due to an increase in the valuation allowance related to state credit carry-forwards generated in the fiscal year ended June 30, 2024. The valuation allowance is based on our assessment that it is more likely than not that certain deferred tax assets will not be realized in the foreseeable future. Of the valuation allowance as of June 30, 2024, $285.4 million was related to federal and state credit carry-forwards. The remainder of the valuation allowance was related to state and foreign NOL carry-forwards. As of June 30, 2024, we intend to indefinitely reinvest $185.9 million of cumulative undistributed earnings held by certain non-U.S. subsidiaries. If these undistributed earnings were repatriated to the U.S., the potential deferred tax liability associated with the undistributed earnings would be approximately $39 million. We benefit from tax holidays in Singapore where we manufacture certain of our products. These tax holidays are on approved investments. The tax holidays in Singapore are scheduled to expire in five The reconciliation of the U.S. federal statutory income tax rate to our effective income tax rate was as follows: Year ended June 30, 2024 2023 2022 Federal statutory rate 21.0 % 21.0 % 21.0 % GILTI 3.7 % 3.4 % 2.0 % Goodwill impairment 1.7 % — % — % Net change in tax reserves 1.1 % — % 2.0 % State income taxes, net of federal benefit 0.3 % 0.2 % 0.3 % Restructuring — % — % (11.2) % Effect of SBC — % 0.1 % (0.2) % R&D tax credit (1.6) % (1.5) % (1.1) % Foreign derived intangible income (5.9) % (5.7) % (4.0) % Effect of foreign operations taxed at various rates (6.6) % (7.1) % (4.2) % Other (0.3) % 0.2 % 0.2 % Effective income tax rate 13.4 % 10.6 % 4.8 % A reconciliation of gross unrecognized tax benefits was as follows: Year Ended June 30, (In thousands) 2024 2023 2022 Unrecognized tax benefits at the beginning of the year $ 213,092 $ 217,927 $ 149,642 Increases for tax positions taken in current year 40,209 44,590 49,311 Increases for tax positions taken in prior years 23,291 434 20,917 Decreases for settlements with taxing authorities — (45,042) — Decreases for tax positions taken in prior years (26,766) (3,929) (267) Decreases for lapsing of statutes of limitations (4,119) (888) (1,676) Unrecognized tax benefits at the end of the year $ 245,707 $ 213,092 $ 217,927 The amounts of unrecognized tax benefits that would impact the effective tax rate were $244.6 million, $199.0 million and $205.0 million as of June 30, 2024, 2023 and 2022, respectively. The amounts of interest and penalties recognized during the years ended June 30, 2024, 2023 and 2022 were expenses (benefits) of $8.3 million, $(20.2) million and $11.5 million, respectively. Our policy is to include interest and penalties related to unrecognized tax benefits within Other expense (income), net. The amounts of interest and penalties accrued as of June 30, 2024 and 2023 were $41.1 million and $32.6 million, respectively. In the normal course of business, we are subject to examination by tax authorities throughout the world. We are subject to U.S. federal income tax examinations for all years beginning from the fiscal year ended June 30, 2018 and are under U.S. federal income tax examination for the fiscal years ended June 30, 2018, 2019 and 2020. We are subject to state income tax examinations for all years beginning from the fiscal year ended June 30, 2020. We are also subject to examinations in other major foreign jurisdictions, including Singapore and Israel, for all years beginning from the calendar year ended December 31, 2019 and are under audit in Israel for the period from January 1, 2019 to June 30, 2022. We have changed our year end in Israel to a fiscal year ending June 30. In August 2022, Orbotech executed a settlement agreement with the Israel Tax Authority (“ITA”) in resolution of tax examinations for fiscal years 2012 through 2014 and 2015 through 2018. The settlement agreement included a payment of approximately $25.7 million, including interest, to the ITA. In addition, Orbotech paid approximately $16.2 million to the ITA related to previous “tax exempt” earnings under the historical Approved or Beneficial Enterprises regimes. The current year election to pay tax on the previous exempt earnings was made under the Temporary Order issued in the Israel Budget, which allows for a reduced tax rate on such earnings. Approximately $5.7 million of the settlement payment related to the amount of R&D expenses eligible for deduction during the above referenced years was refunded to Orbotech in January 2023. We believe that we may recognize up to $16.5 million of our existing unrecognized tax benefits within the next 12 months as a result of the lapse of statutes of limitations. It is possible that certain income tax examinations may be concluded in the next 12 months. Given the uncertainty around the timing of the resolution of these ongoing examinations, we are unable to estimate the full range of possible adjustments to our unrecognized tax benefits within the next 12 months. Legislative Developments President Biden signed into law the CHIPS and Science Act of 2022 (“CHIPS Act,” where “CHIPS” stands for Creating Helpful Incentives to Produce Semiconductors) on August 9, 2022. The CHIPS Act provides for various incentives and tax credits among other items, including the Advanced Manufacturing Investment Credit (“AMIC”), which equals 25% of qualified investments in an advanced manufacturing facility that is placed in service after December 31, 2022. There was no material impact to our financial statements from the AMIC provision. President Biden also signed into law the IRA on August 16, 2022. The IRA has several provisions including a 15% corporate alternative minimum tax (“CAMT”) for certain large corporations that have at least an average of $1.0 billion of adjusted financial statement income over a consecutive three-tax-year period. The CAMT was effective for us beginning in our fiscal year ending June 30, 2024 and there was no tax impact to our financial statements from the CAMT provision. The IRA also introduced a 1% excise tax imposed on certain stock repurchases by publicly traded companies made after December 31, 2022. We began recording the excise tax as part of the cost basis of treasury stock repurchased after December 31, 2022. Other than the AMIC and the excise tax imposed on certain stock repurchases as mentioned above, we are currently evaluating the applicability and impact of the other provisions in the IRA and the CHIPS Act on our Consolidated Financial Statements including our future cash flows. California Governor Newsom approved the 2024-25 California State Budget on June 27, 2024, which includes a provision to suspend the use of all net operating losses and limits the use of R&D tax credits to $5 million for tax years 2024 through 2026. This provision will be effective in our fiscal years ending June 30, 2025 through June 30, 2027. We do not expect these modifications to have any impact to our Consolidated Financial Statements.

Loss Contingency, Information about Litigation Matters [Abstract]
LITIGATION AND OTHER LEGAL MATTERS	LITIGATION AND OTHER LEGAL MATTERS We are named, from time to time, as a party to lawsuits and other types of legal proceedings and claims in the normal course of our business. Actions filed against us include commercial, intellectual property (“IP”), customer, and labor and employment related claims, including complaints of alleged wrongful termination and potential class action lawsuits regarding alleged violations of federal and state wage and hour and other laws. In general, legal proceedings and claims, regardless of their merit, and associated internal investigations (especially those relating to IP or confidential information disputes) are often expensive to prosecute, defend or conduct and may divert management’s attention and other company resources. Moreover, the results of legal proceedings are difficult to predict, and the costs incurred in litigation can be substantial, regardless of outcome. We believe the amounts provided in our Consolidated Financial Statements are adequate in light of the probable and estimated liabilities. However, because such matters are subject to many uncertainties and the ultimate outcomes are not predictable, there can be no assurances that the actual amounts required to satisfy alleged liabilities from the matters described above will not exceed the amounts reflected in our Consolidated Financial Statements or will not have a material adverse effect on our results of operations, financial condition or cash flows.

Commitments and Contingencies Disclosure [Abstract]
COMMITMENTS AND CONTINGENCIES	COMMITMENTS AND CONTINGENCIES Factoring. We have factoring agreements with financial institutions to sell certain of our trade receivables and promissory notes from customers without recourse. We do not believe we are at risk for any material losses as a result of these agreements. In addition, we periodically sell certain LC, without recourse, received from customers in payment for goods and services. The following table shows total receivables sold under factoring agreements and proceeds from sales of LC for the indicated periods: Year Ended June 30, (In thousands) 2024 2023 2022 Receivables sold under factoring agreements $ 254,889 $ 328,933 $ 250,983 Proceeds from sales of LC $ 22,242 $ 69,247 $ 151,924 Factoring and LC fees for the sale of certain trade receivables were recorded in Other expense (income), net and were not material for the periods presented. Purchase Commitments. We maintain commitments to purchase inventory from our suppliers as well as goods, services, and other assets in the ordinary course of business. Our liability under these purchase commitments is generally restricted to a forecasted time-horizon as mutually agreed between the parties. This forecasted time-horizon can vary among different suppliers. Our estimate of our significant purchase commitments primarily for material, services, supplies and asset purchases is $2.17 billion as of June 30, 2024, a majority of which will be due within the next 12 months. Actual expenditures will vary based upon the volume of the transactions and length of contractual service provided. In addition, the amounts paid under these arrangements may be less in the event that the arrangements are renegotiated or canceled. Certain agreements provide for potential cancellation penalties. Cash LTI Plan. As of June 30, 2024, we have committed $143.1 million for future payment obligations under our Cash LTI Plan. Cash LTI awards issued to employees under the Cash LTI Plan vest in three or four equal installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each anniversary of the grant date over a three Guarantees and Contingencies. We maintain guarantee arrangements available through various financial institutions for up to $83.9 million, of which $49.9 million had been issued as of June 30, 2024, primarily to fund guarantees to customs authorities for value-added tax and other operating requirements of our consolidated subsidiaries in Europe, Israel and Asia. Indemnification Obligations. Subject to certain limitations, we are obligated to indemnify our current and former directors, officers and employees with respect to certain litigation matters and investigations that arise in connection with their service to us. These obligations arise under the terms of our certificate of incorporation, bylaws, applicable contracts, and Delaware and California law. The obligation to indemnify generally means that we are required to pay or reimburse the individuals’ reasonable legal expenses and possibly damages and other liabilities incurred by several of our current and former directors, officers and employees in connection with these matters. For example, we have paid or reimbursed legal expenses incurred in connection with the investigation of our historical stock option practices and the related litigation and government inquiries. Although the maximum potential amount of future payments we could be required to make under the indemnification obligations generally described in this paragraph is theoretically unlimited, we believe the fair value of this liability, to the extent estimable, is appropriately considered within the reserve we have established for currently pending legal proceedings. We are a party to a variety of agreements pursuant to which we may be obligated to indemnify the other party with respect to certain matters. Typically, these obligations arise in connection with contracts and license agreements or the sale of assets, under which we customarily agree to hold the other party harmless against losses arising therefrom, or provide customers with other remedies to protect against, bodily injury or damage to personal property caused by our products, non-compliance with our product performance specifications, infringement by our products of third-party IP rights and a breach of warranties, representations and covenants related to matters such as title to assets sold, validity of certain IP rights, non-infringement of third-party rights, and certain income tax-related matters. In each of these circumstances, payment by us is typically subject to the other party making a claim to and cooperating with us pursuant to the procedures specified in the particular contract. This usually allows us to challenge the other party’s claims or, in case of breach of IP representations or covenants, to control the defense or settlement of any third-party claims brought against the other party. Further, our obligations under these agreements may be limited in terms of amounts, activity (typically at our option to replace or correct the products or terminate the agreement with a refund to the other party), and duration. In some instances, we may have recourse against third parties and/or insurance covering certain payments made by us. In addition, we may, in limited circumstances, enter into agreements that contain customer-specific commitments on pricing, tool reliability, spare parts stocking levels, response time and other commitments. Furthermore, we may give these customers limited audit or inspection rights to enable them to confirm that we are complying with these commitments. If a customer elects to exercise its audit or inspection rights, we may be required to expend significant resources to support the audit or inspection, as well as to defend or settle any dispute with a customer that could potentially arise out of such audit or inspection. To date, we have made no significant accruals in our Consolidated Financial Statements for this contingency. While we have not in the past incurred significant expenses for resolving disputes regarding these types of commitments, we cannot make any assurance that it will not incur any such liabilities in the future. It is not possible to predict the maximum potential amount of future payments under these or similar agreements due to the conditional nature of our obligations and the unique facts and circumstances involved in each particular agreement. Historically, payments made by us under these agreements have not had a material effect on our business, financial condition, results of operations or cash flows.

DERIVATIVE INSTRUMENTS AND HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	12 Months Ended

Derivative Instruments and Hedging Activities Disclosure [Abstract]
DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES The authoritative guidance requires companies to recognize all derivative instruments, including foreign exchange contracts and rate lock agreements (collectively “derivatives”) as either assets or liabilities at fair value on the Consolidated Balance Sheets. In accordance with the accounting guidance, we designate foreign currency forward transactions and options contracts and interest rate forward transactions as cash flow hedges. In accordance with the accounting guidance, we also designate certain foreign currency exchange contracts as net investment hedge transactions intended to mitigate the variability of the value of certain investments in foreign subsidiaries. Our foreign subsidiaries operate and sell our products in various global markets. As a result, we are exposed to risks relating to changes in foreign currency exchange rates. We utilize foreign exchange contracts to hedge against future movements in foreign currency exchange rates that affect certain existing and forecasted foreign currency denominated sales and purchase transactions, such as the Japanese yen, the euro, the pound sterling and the new Israeli shekel. We routinely hedge our exposures to certain foreign currencies with various financial institutions in an effort to minimize the impact of certain currency exchange rate fluctuations. These foreign exchange contracts, designated as cash flow hedges, generally have maturities of less than 18 months. Cash flow hedges are evaluated for effectiveness monthly, based on changes in total fair value of the derivatives. If a financial counterparty to any of our hedging arrangements experiences financial difficulties or is otherwise unable to honor the terms of the foreign currency hedge, we may experience material losses. Since fiscal 2015, we have entered into five sets of Rate Lock Agreements to hedge the benchmark interest rate on portions of our Senior Notes prior to issuance. Upon issuance of the associated debt, the Rate Lock Agreements were settled and their fair values were recorded within AOCI. The resulting gains and losses from these transactions are amortized to interest expense over the lives of the associated debt. As of June 30, 2024, the aggregate unamortized portion of the fair value of the Rate Lock Agreements was a $47.7 million net gain. For derivatives that are designated and qualify as cash flow hedges, the effective portion of the gains or losses is reported in AOCI and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. For derivative contracts executed after adopting the new accounting guidance in fiscal 2019, the election to include time value for the assessment of effectiveness is made on all forward contracts designated as cash flow hedges. The change in fair value of the derivative is recorded in AOCI until the hedged item is recognized in earnings. The assessment of effectiveness of options contracts designated as cash flow hedges exclude time value. The initial value of the component excluded from the assessment of effectiveness is recognized in earnings over the life of the derivative contract. Any difference between change in the fair value of the excluded components and the amounts recognized in earnings are recorded in AOCI. For derivatives that are designated and qualify as a net investment hedge in a foreign operation and that meet the effectiveness requirements, the net gains or losses attributable to changes in spot exchange rates are recorded in cumulative translation within AOCI. The remainder of the change in value of such instruments is recorded in earnings using the mark-to-market approach. Recognition in earnings of amounts previously recorded in cumulative translation is limited to circumstances such as complete or substantially complete liquidation or sale of the net investment in the hedged foreign operations. For derivatives that are not designated as hedges, gains and losses are recognized in Other expense (income), net. We use foreign exchange contracts to hedge certain foreign currency denominated assets or liabilities. The gains and losses on these derivative instruments are largely offset by the changes in the fair value of the assets or liabilities being hedged. Derivatives in Hedging Relationships: Foreign Exchange Contracts and Rate Lock Agreements The gains (losses) on derivatives in cash flow and net investment hedging relationships recognized in OCI for the indicated periods were as follows: Year Ended June 30, (In thousands) 2024 2023 2022 Derivatives Designated as Cash Flow Hedging Instruments: Rate lock agreements: Amounts included in the assessment of effectiveness $ 415 $ — $ 82,969 Foreign exchange contracts: Amounts included in the assessment of effectiveness $ 9,176 $ 30,153 $ 21,940 Amounts excluded from the assessment of effectiveness $ 146 $ (128) $ 43 Derivatives Designated as Net Investment Hedging Instruments: Foreign exchange contracts (1) $ 3,459 $ 3,626 $ 3,815 ________________ (1) No amounts were reclassified from AOCI into earnings related to the sale of a subsidiary.

Segment Reporting [Abstract]
SEGMENT REPORTING AND GEOGRAPHIC INFORMATION	SEGMENT REPORTING AND GEOGRAPHIC INFORMATION ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer. We have three reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection. The reportable segments are determined based on several factors including, but not limited to, customer base, homogeneity of products, technology, delivery channels and similar economic characteristics. Semiconductor Process Control The Semiconductor Process Control segment offers a comprehensive portfolio of inspection, metrology and data analytics products, and related services, which helps IC manufacturers achieve target yield throughout the entire semiconductor fabrication process, from R&D to final volume production. Our differentiated products and services are designed to provide comprehensive solutions that help our customers accelerate development and production ramp cycles, achieve higher and more stable semiconductor die yields and improve their overall profitability. This reportable segment is comprised of two operating segments, Wafer Inspection and Patterning and GSS. Specialty Semiconductor Process The Specialty Semiconductor Process segment develops and sells advanced vacuum deposition and etching process tools, which are used by a broad range of specialty semiconductor customers, including manufacturers of MEMS, radio frequency communication chips, and power semiconductors for automotive and industrial applications. This reportable segment is comprised of one operating segment. PCB and Component Inspection The PCB and Component Inspection segment enables electronic device manufacturers to inspect, test and measure PCBs, FPDs and ICs to verify their quality, pattern the desired electronic circuitry on the relevant substrate and perform three-dimensional shaping of metalized circuits on multiple surfaces. This reportable segment is comprised of two operating segments, PCB and Component Inspection. In March 2024, we made the decision to exit the Display business by announcing the end of manufacturing of most Display products by December 31, 2024, but we will continue to provide services to the installed base of Display products for existing customers. The CODM assesses the performance of each operating segment and allocates resources to those segments based on total revenues and segment gross profit and does not evaluate the segments using discrete asset information. Segment gross profit excludes corporate allocations and effects of changes in foreign currency exchange rates, amortization of intangible assets, amortization of inventory fair value adjustments, and transaction costs associated with our acquisitions related to costs of revenues. The following is a summary of results for each of our three reportable segments for the indicated periods. Year Ended June 30, (In thousands) 2024 2023 2022 Semiconductor Process Control: Revenues $ 8,733,556 $ 9,324,190 $ 7,924,822 Segment gross profit $ 5,629,302 $ 5,957,573 $ 5,167,679 Specialty Semiconductor Process: Revenues $ 528,701 $ 543,398 $ 456,579 Segment gross profit $ 282,910 $ 281,942 $ 242,520 PCB and Component Inspection: Revenues $ 552,491 $ 631,604 $ 832,176 Segment gross profit $ 158,960 $ 221,251 $ 378,964 Totals: Revenues for reportable segments $ 9,814,748 $ 10,499,192 $ 9,213,577 Segment gross profit $ 6,071,172 $ 6,460,766 $ 5,789,163 The following table reconciles total reportable segment revenue to total revenue for the indicated periods: Year Ended June 30, (In thousands) 2024 2023 2022 Total revenues for reportable segments $ 9,814,748 $ 10,499,192 $ 9,213,577 Corporate allocations and effects of changes in foreign currency exchange rates (2,501) (3,136) (1,694) Total revenues $ 9,812,247 $ 10,496,056 $ 9,211,883 The following table reconciles total segment gross profit to total income before income taxes for the indicated periods: Year Ended June 30, (In thousands) 2024 2023 2022 Total segment gross profit $ 6,071,172 $ 6,460,766 $ 5,789,163 Acquisition-related charges, corporate allocations and effects of changes in foreign currency exchange rates (1) 186,998 183,017 169,721 R&D 1,278,981 1,296,727 1,105,254 SG&A 969,509 986,326 860,007 Impairment of goodwill and purchased intangible assets 289,474 — — Interest expense 311,253 296,940 160,339 Loss on extinguishment of debt — 13,286 — Other expense (income), net (155,075) (104,720) 4,605 Income before income taxes $ 3,190,032 $ 3,789,190 $ 3,489,237 __________________ (1) Acquisition-related charges primarily include amortization of intangible assets and other acquisition-related costs classified or presented as part of Costs of revenues.

Accounting Policies [Abstract]
Description of Business and Principles of Consolidation	Description of Business and Principles of Consolidation. KLA Corporation and its majority-owned subsidiaries (“KLA” or the “Company” and also referred to as “we,” “our,” “us” or similar references) is a supplier of process equipment, process control equipment, and data analytics products for a broad range of industries, including semiconductors and printed circuit boards (“PCB”). We provide advanced process control and process-enabling solutions for manufacturing and testing wafers and reticles, integrated circuits (“IC”), advanced packaging, light-emitting diodes, power devices, compound semiconductor devices, microelectromechanical systems (“MEMS”), data storage and PCBs as well as general materials research. We also provide comprehensive support and services across our installed base. Our extensive portfolio of inspection, metrology and data analytics products, and related services, helps IC manufacturers achieve target yield throughout the entire semiconductor fabrication process, from research and development (“R&D”) to final volume production. We develop and sell advanced vacuum deposition and etching process tools, which are used by a broad range of specialty semiconductor customers. We enable electronic device manufacturers to inspect, test and measure PCBs and ICs to verify their quality, deposit a pattern of desired electronic circuitry on the relevant substrate and perform three-dimensional shaping of metalized circuits on multiple surfaces. Our advanced products, coupled with our unique yield management software and services, allow us to deliver the solutions our semiconductor and PCB customers need to achieve their productivity goals by significantly reducing their risks and costs and improving their overall profitability and return on investment. Headquartered in Milpitas, California, we have subsidiaries both in the U.S. and key markets throughout the world. The Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated.
Comparability	Comparability. Certain reclassifications have been made to the prior year’s Consolidated Financial Statements to conform to the current year presentation. The reclassifications did not have material effects on the prior year’s Consolidated Balance Sheets, Statements of Operations, Comprehensive Income and Cash Flows.
Management Estimates	Management Estimates. The preparation of the Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in applying our accounting policies that affect the reported amounts of assets and liabilities (and related disclosure of contingent assets and liabilities) at the date of the Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Cash Equivalents and Fixed Income Marketable Securities	Cash Equivalents and Fixed Income Marketable Securities . All highly liquid debt instruments with original or remaining maturities of less than three months at the date of purchase are cash equivalents. Fixed income marketable securities are generally classified as available-for-sale for use in current operations, if required, and are reported at fair value, with unrealized gains and non-credit related unrealized losses, net of tax, presented as a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income (loss).” All realized gains and losses are recorded in earnings in the period of occurrence. The specific identification method is used to determine the realized gains and losses on investments. We regularly review the available-for-sale debt securities in an unrealized loss position and evaluate the current expected credit loss by considering available information relevant to the collectability of the security, such as historical experience, market data, issuer-specific factors including credit ratings, default and loss rates of the underlying collateral and structure and credit enhancements, current economic conditions and reasonable and supportable forecasts. There were no credit losses on available-for-sale debt securities recognized in the years ended June 30, 2024, 2023 and 2022. If we do not expect to recover the entire amortized cost of the security, the amount representing credit losses, defined as the difference between the present value of the cash flows expected to be collected and the amortized cost basis of the debt security, is recorded as an allowance for credit losses with an offsetting entry to net income, and the amount that is not credit-related is recognized in other comprehensive income (loss) (“OCI”). If we have the intent to sell the security or it is more likely than not that we will be required to sell the security before recovery of its entire amortized cost basis, we first write off any previously recognized allowance for credit losses with an offsetting entry to the security’s amortized cost basis. If the allowance has been fully written off and fair value is less than amortized cost basis, we write down the amortized cost basis of the security to its fair value with an offsetting entry to net income.

Investments in Equity Securities	Investments in Equity Securities. We hold equity securities in publicly and privately held companies for the promotion of business and strategic objectives. Equity securities in publicly held companies, or marketable equity securities, are measured and recorded at fair value on a recurring basis. Equity securities in privately held companies, or non-marketable equity securities, are accounted for at cost, less impairment, plus or minus observable price changes in orderly transactions for identical or similar securities of the same issuer. Non-marketable equity securities are subject to a periodic impairment review; however, since there are no open-market valuations, the impairment analysis requires significant judgment. This analysis includes assessment of the investee’s financial condition, the business outlook for its products and technology, its projected results and cash flow, financing transactions subsequent to the acquisition of the investment, the likelihood of obtaining subsequent rounds of financing and the impact of any relevant contractual equity preferences held by us or the others. Non-marketable equity securities are included in “Other non-current assets” on the balance sheet. Realized and unrealized gains and losses resulting from changes in fair value or the sale of our marketable and non-marketable equity securities are recorded in Other expense (income), net.
Variable Interest Entities	Variable Interest Entities. We use a qualitative approach in assessing the consolidation requirement for variable interest entities. The approach focuses on identifying which enterprise has the power to direct the activities that most significantly impact the variable interest entity’s economic performance and which enterprise has the obligation to absorb losses or the right to receive benefits from the variable interest entity. In the event we are the primary beneficiary of a variable interest entity, the assets, liabilities, and results of operations of the variable interest entity will be included in our Consolidated Financial Statements. We have concluded that none of our equity investments require consolidation based on our most recent qualitative assessment.
Inventory Valuation	Inventory Valuation. Inventories are stated at the lower of cost or net realizable value using standard costs that approximate actual costs on a first-in, first-out basis. The carrying value of product inventory is reduced for estimated obsolescence equal to the difference between its cost and the estimated net realizable value based on assumptions about future demand for meeting our product manufacturing plans. The carrying value of service inventory is reduced for estimated obsolescence equal to the difference between its cost and the estimated net realizable value based on assumptions about future demand to meet our customers’ support requirements. Demonstration units are stated at their manufacturing cost and written down to their net realizable value. The Company’s policy is to assess the valuation of all inventories including manufacturing raw materials, work-in-process, finished goods and spare parts in each reporting period. The estimate of net realizable value of inventory is impacted by assumptions regarding general semiconductor market conditions, manufacturing schedules, technology changes, new product introductions and possible alternative uses, and require us to use significant judgment that may include uncertain elements. Actual demand may differ from forecasted demand, and such differences may have a material effect on recorded inventory values. Our manufacturing overhead standards for product costs are calculated assuming full absorption of forecasted spending over projected volumes, adjusted for excess capacity. Abnormal inventory costs such as costs of idle facilities, excess freight and handling costs and spoilage are recognized as current period charges.
Allowance for Credit Losses	Allowance for Credit Losses. A majority of our accounts receivable are derived from sales to large multinational semiconductor and electronics manufacturers throughout the world. We maintain an allowance for credit losses for expected uncollectible accounts receivable, which is recorded as an offset to accounts receivable and changes in such are classified as selling, general and administrative (“SG&A”) expense in the Consolidated Statements of Operations. We assess collectability by reviewing accounts receivable on a collective basis where similar risk characteristics exist and on an individual basis when we identify specific customers with known disputes or collectability issues. The estimate of expected credit losses considers historical credit loss information that is adjusted for current conditions and reasonable and supportable forecasts. The allowance for credit losses is reviewed on a quarterly basis to assess the adequacy of the allowance. Our assessment considered estimates of expected credit and collectability trends. The credit losses recognized on accounts receivable were not significant as of June 30, 2024 and 2023 . Volatility in market conditions and evolving credit trends are difficult to predict and may cause variability that may have a material impact on our allowance for credit losses in future periods.
Property and Equipment	Property and Equipment. Property and equipment are recorded at cost, net of accumulated depreciation. Depreciation of property and equipment is based on the straight-line method over the estimated useful lives of the assets. The following table sets forth the estimated useful life for various asset categories: Asset Category Range of Useful Lives Buildings 30 to 50 years Leasehold improvements Shorter of 15 years or lease term Machinery and equipment 2 to 10 years Office furniture and fixtures 7 years
Leases	Leases . Under Accounting Standards Codification (“ASC”) 842, Leases, a contract is or contains a lease when we have the right to control the use of an identified asset for a period of time. We determine if an arrangement is a lease at inception of the contract, which is the date on which the terms of the contract are agreed to, and the agreement creates enforceable rights and obligations. The commencement date of the lease is the date that the lessor makes an underlying asset available for our use. On the commencement date, leases are evaluated for classification and assets and liabilities are recognized based on the present value of lease payments over the lease term. The lease term used to calculate the lease liability includes options to extend or terminate the lease when it is reasonably certain that the option will be exercised. The right of use (“ROU”) asset is initially measured as the amount of lease liability, adjusted for any initial lease costs, prepaid lease payments and any lease incentives. Variable lease payments, consisting primarily of reimbursement of costs incurred by lessors for common area maintenance, real estate taxes and insurance, are not included in the lease liability and are recognized as they are incurred. As most of our leases do not provide an implicit rate, we use our incremental borrowing rate at lease commencement to measure ROU assets and lease liabilities. The incremental borrowing rate used by us is based on baseline rates and adjusted by the credit spreads commensurate with our secured borrowing rate, over a similar term. We used the incremental borrowing rate on June 30, 2019 for all leases that commenced on or prior to that date. Operating lease expense is generally recognized on a straight-line basis over the lease term. We have elected the practical expedient to account for the lease and non-lease components as a single lease component for the majority of our asset classes. For leases with a term of one year or less, we have elected not to record the ROU asset or liability.
Goodwill, Purchased Intangible Assets and Impairment Assessment	Goodwill, Purchased Intangible Assets and Impairment Assessment. Goodwill represents the excess of the purchase price in a business combination over the fair value of the net tangible and intangible assets acquired. We assess goodwill for impairment annually during our third fiscal quarter or whenever events or changes in circumstances indicate the carrying value may not be fully recoverable. We have the option to perform a qualitative assessment prior to necessitating a quantitative impairment test. In the qualitative assessment, if we determine that it is more likely than not that the fair value of a reporting unit is less than the carrying value, a quantitative test is then performed, which involves comparing the estimated fair value of a reporting unit to its carrying value including goodwill. If goodwill is considered to be impaired, the amount of any impairment is measured as the difference between the carrying value and the fair value. Refer to Note 7 “Goodwill and Purchased Intangible Assets” for information related to determining the fair value of a reporting unit.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets.
Concentration of Credit Risk	Concentration of Credit Risk. Financial instruments that potentially subject us to significant concentrations of credit risk consist primarily of cash equivalents, short-term marketable securities, trade accounts receivable and derivative financial instruments used in hedging activities. We invest in a variety of financial instruments, such as, but not limited to, certificates of deposit, corporate debt and municipal securities, U.S. Treasury and Government agency securities, and equity securities and, by policy, we limit the amount of credit exposure with any one financial institution or commercial issuer. We have not experienced any material credit losses on our investments. A majority of our accounts receivable are derived from sales to large multinational semiconductor and electronics manufacturers located throughout the world, with a majority located in Asia. In recent years, our customer base has become increasingly concentrated due to corporate consolidations, acquisitions and business closures, and to the extent that these customers experience liquidity issues in the future, we may be required to reserve for potential credit losses with respect to trade receivables. We perform ongoing credit evaluations of our customers’ financial condition and generally require little to no collateral to secure accounts receivable. We maintain an allowance for potential credit losses based upon expected collectability risk of all accounts receivable. In addition, we may utilize letters of credit (“LC”) or non-recourse factoring to mitigate credit risk when considered appropriate. We are exposed to credit loss in the event of non-performance by counterparties on the foreign exchange contracts that we use in hedging activities and in certain factoring transactions. These counterparties are large international financial institutions, and, to date, no such counterparty has failed to meet its financial obligations to us under such contracts.
Foreign Currency	Foreign Currency. The functional currencies of our foreign subsidiaries are primarily the local currencies, except as described below. Accordingly, all assets and liabilities of these foreign operations are translated to U.S. dollars at current period end exchange rates, and revenues and expenses are translated to U.S. dollars using average exchange rates in effect during the period. The gains and losses from foreign currency translation of these subsidiaries’ financial statements are recorded directly into a separate component of stockholders’ equity under the caption “Accumulated other comprehensive income (loss).” Our manufacturing subsidiaries in Singapore, Israel, Germany, and the United Kingdom use the U.S. dollar as their functional currency. Accordingly, monetary assets and liabilities in non-functional currency of these subsidiaries are remeasured using exchange rates in effect at the end of the period. Revenues and costs in local currency are remeasured using average exchange rates for the period, except for costs related to those balance sheet items that are remeasured using historical exchange rates. The resulting remeasurement gains and losses are included in the Consolidated Statements of Operations as incurred.
Derivative Financial Instruments	Derivative Financial Instruments. We use financial instruments, such as foreign exchange contracts including forward and options transactions, to hedge a portion of, but not all, existing and forecasted foreign currency denominated transactions. The purpose of our foreign exchange hedging program is to manage the effect of exchange rate fluctuations on certain foreign currency denominated revenues, costs and eventual cash flows. The effect of exchange rate changes on foreign exchange contracts is expected to offset the effect of exchange rate changes on the underlying hedged items. We also use forward contracts to hedge the risk associated with the variability of cash flows due to changes in the benchmark interest rate of the intended debt financing (“Rate Lock Agreements”). We believe these financial instruments do not subject us to speculative risk that would otherwise result from changes in currency exchange rates or interest rates. All of our derivative financial instruments are recorded at fair value based upon quoted market prices for comparable instruments adjusted for risk of counterparty non-performance. For derivative instruments designated and qualifying as cash flow hedges of forecasted foreign currency denominated transactions or debt financing, the effective portion of the gains or losses is reported in Accumulated other comprehensive income (loss) (“AOCI”) and reclassified into earnings in the same period or periods during which the hedged transaction affects earnings. We elected to include time value for the assessment of effectiveness on all forward transactions designated as cash flow hedges. The change in fair value of the derivative is recorded in AOCI until the hedged transaction is recognized in earnings. The assessment of effectiveness of options contracts designated as cash flow hedges excludes time value. The initial value of the component excluded from the assessment of effectiveness is recognized in earnings over the life of the derivative contract. Any differences between change in the fair value of the excluded components and the amounts recognized in earnings are recorded in AOCI. For foreign exchange contracts that are designated and qualify as a net investment hedge in a foreign operation and that meet the effectiveness requirements, the net gains or losses attributable to changes in spot exchange rates are recorded in cumulative translation within AOCI. The remainder of the change in value of such instruments is recorded in earnings using the mark-to-market approach. Recognition in earnings of amounts previously recorded in cumulative translation is limited to circumstances such as complete or substantially complete liquidation of the net investment in the hedged foreign operations. For foreign exchange contracts that are not designated as hedges, gains and losses are recognized in Other expense (income), net. We use foreign exchange contracts to hedge certain foreign currency denominated assets or liabilities. The gains and losses on these derivative instruments are largely offset by the changes in the fair value of the assets or liabilities being hedged.
Revenue Recognition	Revenue Recognition. We primarily derive revenue from the sale of process control and process-enabling solutions for the semiconductor and related electronics industries, maintenance and support of all these products, installation and training services and the sale of spare parts. Our portfolio includes yield enhancement and production solutions for manufacturing wafers and reticles, ICs, packaging, PCBs and flat panel displays (“FPD”), as well as comprehensive support and services across our installed base. Our solutions are generally not sold with a right of return, nor have we experienced significant returns from or refunds to our customers. We account for a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Our revenues are measured based on consideration stipulated in the arrangement with each customer, net of any sales incentives and amounts collected on behalf of third parties, such as sales taxes. The revenues are recognized as separate performance obligations that are satisfied by transferring control of the product or service to the customer. Our arrangements with our customers include various combinations of products and services, which are generally capable of being distinct and accounted for as separate performance obligations. A product or service is considered distinct if it is separately identifiable from other deliverables in the arrangement and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The transaction consideration, including any sales incentives, is allocated between separate performance obligations of an arrangement based on the stand-alone selling price (“SSP”) for each distinct product or service. Management considers a variety of factors to determine the SSP, such as historical stand-alone sales of products and services, discounting strategies and other observable data. From time to time, our contracts are modified to account for additional, or to change existing, performance obligations. Our contract modifications are generally accounted for prospectively. Product Revenue We recognize revenue from product sales at a point in time when we have satisfied our performance obligation by transferring control of the product to the customer. We use judgment to evaluate whether control has transferred by considering several indicators, including whether: • We have a present right to payment; • The customer has legal title; • The customer has physical possession; • The customer has significant risk and rewards of ownership; and • The customer has accepted the product, or whether customer acceptance is considered a formality based on history of acceptance of similar products (for example, when the customer has previously accepted the same tool, with the same specifications, and when we can objectively demonstrate that the tool meets all of the required acceptance criteria, and when the installation of the system is deemed perfunctory). Not all of the indicators need to be met for us to conclude that control has transferred to the customer. In circumstances in which revenue is recognized prior to the product acceptance, the fair value of revenue associated with our performance obligations to install the product is deferred and recognized as revenue at a point in time, once installation is complete. We enter into volume purchase agreements with some of our customers. We adjust the transaction consideration for estimated credits and incentives earned by our customers. These credits are estimated based upon the forecasted and actual product sales for any given period and agreed incentive rate. The estimate is reviewed for material changes and updated at each reporting period. We offer perpetual and term licenses for software products. The primary difference between perpetual and term licenses is the duration over which the customer can benefit from the use of the software, while the functionality and the features of the software are the same. Software is generally bundled with post-contract customer support (“PCS”), which includes unspecified software updates that are made available throughout the entire term of the arrangement. Revenue from software licenses is recognized at a point in time, when the software is made available to the customer. Revenue from PCS is deferred at contract inception and recognized ratably over the service period, or as services are performed. Services Revenue The majority of product sales include a standard 12-month warranty that is not separately paid for by the customers. The customers may also purchase an extended warranty for periods beyond the initial period as part of the initial product sale. We have concluded that the standard 12-month warranty as well as any extended warranty periods included in the initial product sales are separate performance obligations for most of our products. The estimated fair value of warranty services is deferred and recognized ratably as revenue over the warranty period, as the customer simultaneously receives and consumes the benefits of warranty services provided by us. Additionally, we offer product maintenance and support services, which the customer may purchase separately from the standard and extended warranty offered as part of the initial product sale. Revenue from separately negotiated maintenance and support service contracts is also recognized over time based on the terms of the applicable service period. Revenue from services performed in the absence of a maintenance contract, including training revenue, is recognized when the related services are performed. We also sell spare parts, revenue from which is recognized when control over the spare parts is transferred to the customer. Significant Judgments Our contracts with our customers often include promises to transfer multiple products and services. Each product and service is generally capable of being distinct within the context of the contract and represents a separate performance obligation. Determining the SSP for each distinct performance obligation and allocation of consideration from an arrangement to the individual performance obligations and the appropriate timing of revenue recognition are significant judgments with respect to these arrangements. We typically estimate the SSP of products and services based on observable transactions when the products and services are sold on a stand-alone basis and those prices fall within a reasonable range. We typically have more than one SSP for individual products and services due to the stratification of these products by customers and circumstances. In these instances, we use information such as the size of the customer, geographic region, as well as customization of the products in determining the SSP. In instances where the SSP is not directly observable, we determine the SSP using information that includes market conditions, entity-specific factors, including discounting strategies, information about the customer or class of customer that is reasonably available and other observable inputs. While changes in the allocation of SSP between performance obligations will not affect the amount of total revenue recognized for a particular contract, any material changes could impact the timing of revenue recognition, which could have a material effect on our financial position and results of operations. Although our products are generally not sold with a right of return, we may provide other credits or sales incentives, which are accounted for either as variable consideration or material right, depending on the specific terms and conditions of the arrangement. These credits and incentives are estimated at contract inception and updated at the end of each reporting period if and when additional information becomes available. As outlined above, we use judgments to evaluate whether or not the customer has obtained control of the product and consider several indicators in evaluating whether or not control has transferred to the customer. Not all of the indicators need to be met for us to conclude that control has transferred to the customer. Contract Assets/Liabilities The timing of revenue recognition, billings and cash collections may result in accounts receivable, contract assets, and contract liabilities (deferred revenue) on our Consolidated Balance Sheets. A receivable is recorded in the period we deliver products or provide services when we have an unconditional right to payment. Contract assets primarily relate to the value of products and services transferred to the customer for which the right to payment is not just dependent on the passage of time. Contract assets are transferred to accounts receivable when rights to payment become unconditional. A contract liability is recognized when we receive payment or have an unconditional right to payment in advance of the satisfaction of performance. The contract liabilities represent (1) deferred product revenue related to the value of products that have been shipped and billed to customers and for which control has not been transferred to the customers, and (2) deferred service revenue, which is recorded when we receive consideration, or such consideration is unconditionally due, from a customer prior to transferring services to the customer under the terms of a contract. Deferred service revenue typically results from warranty services, and maintenance and other service contracts. Contract assets and liabilities related to rights and obligations in a contract are recorded net in the Consolidated Balance Sheets.
Research and Development Costs	Research and Development Costs. R&D costs are expensed as incurred.
Shipping and Handling Costs	Shipping and Handling Costs. Shipping and handling costs are included as a component of cost of sales.
Accounting for Stock-Based Compensation Plans	Accounting for Stock-Based Compensation Plans. We account for stock-based awards granted to employees for services based on the fair value of those awards. The fair value of stock-based awards is measured at the grant date and is recognized as expense over the employee’s requisite service period. The fair value for restricted stock units (“RSU”) granted without “dividend equivalent” rights is determined using the closing price of our common stock on the grant date, adjusted to exclude the present value of dividends which are not accrued on the RSUs. The fair value for RSUs granted with “dividend equivalent” rights is determined using the closing price of our common stock on the grant date. The award holder is not entitled to receive payments under dividend equivalent rights unless the associated RSU award vests (i.e., the award holder is entitled to receive credits, payable in cash or shares of common stock, equal to the cash dividends that would have been received on the shares of our common stock underlying the RSUs had the shares been issued and outstanding on the dividend record date, but such dividend equivalents are only paid subject to the recipient satisfying the vesting requirements of the underlying award). Compensation expense for RSUs with performance metrics is calculated based upon expected achievement of the metrics specified in the grant, or when a grant contains a market condition, the grant date fair value using a Monte Carlo simulation. The Monte Carlo simulation incorporates estimates of the potential outcomes of the market condition on the grant date fair value of each award. Additionally, we estimate forfeitures based on historical experience and revise those estimates in subsequent periods if actual forfeitures differ from the estimated amounts. The fair value for our Employee Stock Purchase Plan (“ESPP”) is determined using a Black-Scholes valuation model for purchase rights. The Black-Scholes option-pricing model requires the input of assumptions, including the option’s expected term and the expected price volatility of the underlying stock. The expected stock price volatility assumption is based on the market-based historical implied volatility from traded options of our common stock.
Accounting for Cash-based Long-Term Incentive Compensation	Accounting for Cash-Based Long-Term Incentive Compensation. Cash-based long-term incentive (“Cash LTI”) awards issued to employees under our Cash Long-Term Incentive Plan (“Cash LTI Plan”) vest in three or four equal installments, with one-third or one-fourth of the aggregate amount of the Cash LTI award vesting on each yearly anniversary of the grant date over a three
Accounting for Non-qualified Deferred Compensation Plan	Accounting for Non-qualified Deferred Compensation Plan. We have a non-qualified deferred compensation plan (known as the “Executive Deferred Savings Plan” (“EDSP”)) under which certain executives and non-employee directors may defer a portion of their compensation. Participants are credited with returns based on their allocation of their account balances among measurement funds. We control the investment of these funds, and the participants remain general creditors of ours. We invest these funds in certain mutual funds and such investments are classified as trading securities in the Consolidated Balance Sheets. Investments in trading securities are measured at fair value in the statement of financial position. Unrealized holding gains and losses for trading securities are included in earnings. Distributions from the EDSP commence following a participant’s retirement or termination of employment or on a specified date allowed per the EDSP provisions, except in cases where such distributions are required to be delayed in order to avoid a prohibited distribution under Internal Revenue Code Section 409A. Participants can generally elect for the distributions to be paid in a lump sum or quarterly cash payments over a scheduled period for up to 15 years and are allowed to make subsequent changes to their existing elections as permissible under the EDSP provisions. The liability associated with the EDSP is included as a component of other current liabilities in the
Income Taxes	Income Taxes. We account for current and deferred income taxes in accordance with the authoritative guidance, which requires that the income tax impact is to be recognized in the period in which the law is enacted. Current income tax expense represents taxes paid or payable for the current period. Deferred tax assets and liabilities are recognized using enacted tax rates for the future tax impact of temporary differences between the financial statement and tax bases of recorded assets and liabilities. A valuation allowance is recorded to reduce deferred tax assets when it is more likely than not that a tax benefit will not be realized based on historical and projected future taxable income over the periods in which the temporary differences are expected to be recovered or settled. We record income taxes on the undistributed earnings of foreign subsidiaries unless the subsidiaries’ earnings are considered indefinitely reinvested outside the U.S. Our income taxes will be greater if some or all of the indefinitely reinvested earnings are taxable when distributed to the U.S. In accordance with the authoritative guidance on accounting for uncertainty in income taxes, we recognize liabilities for uncertain tax positions based on the two-step process. The first step is to evaluate the tax position for recognition by determining if the weight of available evidence indicates that it is more likely than not that the position will be sustained in audit, including resolution of related appeals or litigation processes, if any. The second step is to measure the tax benefit as the largest amount that is more than 50% likely of being realized upon ultimate settlement. Global Intangible Low-Taxed Income. The Tax Cut and Jobs Act includes provisions for Global Intangible Low-Taxed Income (“GILTI”) wherein U.S. taxes on foreign income are imposed in excess of a deemed return on tangible assets of foreign corporations. This income is effectively taxed at a 10.5% tax rate in general. We elect to account for GILTI as a component of current period tax expense and not recognize deferred tax assets and liabilities for the basis differences expected to reverse as a result of GILTI provisions.
Business Combinations	Business Combinations. We allocate the fair value of the purchase price of our acquisitions to the tangible assets acquired, liabilities assumed, and intangible assets acquired, including in-process research and development (“IPR&D”), based on their estimated fair values at acquisition date. The excess of the fair value of the purchase price over the fair values of these net tangible and intangible assets acquired is recorded as goodwill. Management’s estimates of fair value are based upon assumptions believed to be reasonable, but our estimates and assumptions are inherently uncertain and subject to refinement. As a result, during the measurement period, which will not exceed one year from the acquisition date, we record adjustments to the assets acquired and liabilities assumed with the corresponding offset to goodwill. After the conclusion of the measurement period or final determination of the fair value of the purchase price of our acquisitions, whichever comes first, any subsequent adjustments are recorded to our Consolidated Statements of Operations. The fair value of IPR&D is initially capitalized as an intangible asset with an indefinite life and assessed for impairment thereafter whenever events or changes in circumstances indicate that the carrying value of the IPR&D assets may not be recoverable. Impairment of IPR&D is recorded to R&D expenses. When an IPR&D project is completed, the IPR&D is reclassified as an amortizable purchased intangible asset and amortized to costs of revenues over the asset’s estimated useful life. Acquisition-related expenses are recognized separately from the business combination and are expensed as incurred.
Net Income Per Share	Net Income Per Share. Basic net income per share is calculated by dividing net income available to common stockholders by the weighted-average number of common shares outstanding during the period. Diluted net income per share is calculated by using the weighted-average number of common shares outstanding during the period increased to include the number of additional shares of common stock that would have been outstanding if the dilutive potential shares of common stock had been issued. The dilutive effect of RSUs and options is reflected in diluted net income per share by application of the treasury stock method. The dilutive securities are excluded from the computation of diluted net loss per share when a net loss is recorded for the period as their effect would be anti-dilutive.
Contingencies and Litigation	Contingencies and Litigation.
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted In October 2021, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2021-08, Business Combinations (Topic 805), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. The new guidance requires companies to apply revenue guidance to recognize and measure contract assets and contract liabilities from contracts with customers acquired in a business combination at carrying value. Under the prior business combination guidance, such assets and liabilities were recognized by the acquirer at fair value on the acquisition date. We adopted this update beginning in the first quarter of our fiscal year ending June 30, 2024 on a prospective basis. The impact of adopting this update will depend on the magnitude of contract assets and contract liabilities acquired in future acquisitions. Updates Not Yet Effective In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280), Improvements to Reportable Segment Disclosures . The new guidance requires enhanced disclosures about significant segment expenses. This standard update is effective for our annual reports beginning in the fiscal year ending June 30, 2025 and interim period reports beginning in the first quarter of the fiscal year ending June 30, 2026. Early adoption is permitted on a retrospective basis. We are currently evaluating the impact of this ASU on our segment disclosures. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures
Fair Value Measurement	Our financial assets and liabilities are measured and recorded at fair value, except for our debt and certain equity investments in privately held companies. Equity investments without a readily available fair value are accounted for using the measurement alternative. The measurement alternative is calculated as cost minus impairment, if any, plus or minus changes resulting from observable price changes. See Note 8 “Debt” for disclosure of the fair value of our Senior Notes, as defined in that Note. Our non-financial assets, such as goodwill, intangible assets, and land, property and equipment, are assessed for impairment when an event or circumstance indicates that an other-than-temporary decline in value may have occurred.
Fair Value of Financial Instruments	Fair Value of Financial Instruments. We have evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. The fair value of our cash equivalents, accounts receivable, accounts payable and other current assets and liabilities approximate their carrying amounts due to the relatively short maturity of these items. Fair Value Hierarchy. The authoritative guidance for fair value measurements establishes a fair value hierarchy that prioritizes the inputs to valuation techniques used to measure fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). The three levels of the fair value hierarchy are described below: Level 1 Valuations based on quoted prices in active markets for identical assets or liabilities that the entity has the ability to access. Level 2 Valuations based on quoted prices for similar assets or liabilities, quoted prices in markets that are not active, or other inputs that are observable or can be corroborated by observable data for substantially the full term of the assets or liabilities. Level 3 Valuations based on inputs that are supported by little or no market activity and that are significant to the fair value of the assets or liabilities. A financial instrument’s level within the fair value hierarchy is based on the lowest level of any input that is significant to the fair value measurement. There were no transfers between Level 1, Level 2 and Level 3 fair value measurements during the years ended June 30, 2024 and June 30, 2023. The types of instruments valued based on quoted market prices in active markets included money market funds, certain U.S. Treasury securities, U.S. Government agency securities and equity securities. Such instruments are generally classified within Level 1 of the fair value hierarchy. The types of instruments valued based on other observable inputs included corporate debt securities, municipal securities and certain U.S. Treasury securities. The market inputs used to value these instruments generally consist of market yields, reported trades and broker/dealer quotes. Such instruments are generally classified within Level 2 of the fair value hierarchy. The principal market in which we execute our foreign currency contracts is the institutional market in an over-the-counter environment with a relatively high level of price transparency. The market participants generally are large financial institutions. Our foreign currency contracts’ valuation inputs are based on quoted prices and quoted pricing intervals from public data sources and do not involve management judgment. These contracts are typically classified within Level 2 of the fair value hierarchy.
