Organization, Consolidation and Presentation of Financial Statements [Abstract]
BASIS OF PRESENTATION	BASIS OF PRESENTATION Basis of Presentation. For purposes of this report, “KLA,” the “Company,” “we,” “our,” “us” or similar references mean KLA Corporation and its majority-owned subsidiaries unless the context requires otherwise. The Condensed Consolidated Financial Statements have been prepared by us pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited interim Condensed Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for audited financial statements. The balance sheet as of June 30, 2024 was derived from the Company’s audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024, but does not include all disclosures required by GAAP for audited financial statements. The unaudited interim Condensed Consolidated Financial Statements reflect all adjustments (consisting only of normal, recurring adjustments) necessary for a fair statement of the financial position, results of operations, comprehensive income, stockholders’ equity and cash flows for the periods indicated. These Condensed Consolidated Financial Statements and notes, however, should be read in conjunction with Item 8 “Financial Statements and Supplementary Data” included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024. The Condensed Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The results of operations for the three and six months ended December 31, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year ending June 30, 2025. Management Estimates. The preparation of the Condensed Consolidated Financial Statements in conformity with GAAP 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 dates of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates. Reclassifications . The Company has reclassified certain prior period balances to conform to the current year presentation. These reclassifications did not impact any prior amounts of reported total assets, total liabilities, stockholders’ equity, results of operations or cash flows. Significant Accounting Policies. Except for the below additions to our accounting policies, there have been no material changes to our significant accounting policies summarized in Note 1 “Description of Business and Summary of Significant Accounting Policies” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024. Government Incentives. We occasionally receive incentives from governmental entities related to capital expenditures, expenses and other activities, primarily in the form of cash grants and tax credits. Government assistance is recognized when there is reasonable assurance that (1) the Company will comply with relevant conditions; and (2) the assistance will be received. Government incentives related to the acquisition or construction of property, plant and equipment are recognized as a reduction in the carrying amounts of the related assets and reduce depreciation expense over the useful lives of the assets. Incentives related to specific operating activities are offset against the related expense in the period the expense is incurred. Collaborative Arrangements. We assess joint development arrangements to determine whether they are in the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements. In our assessment, we evaluate whether such arrangements involve joint operating activities performed by parties that are both active participants in the activities and exposed to significant risks and rewards dependent on commercial success of the activities. This assessment is performed throughout the life of such arrangement with consideration given to the changes in the roles and responsibilities between the parties. During the quarter ended September 30, 2024, we entered into a joint development arrangement within the scope of ASC 808 to develop and commercialize a new product. Recent Accounting Pronouncements Recently Adopted None Updates Not Yet Effective In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“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 will adopt this update for our annual report for the fiscal year ending June 30, 2025. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures . The new guidance requires enhanced disclosures about income tax expenses. This standard update is effective for our annual reports beginning in the fiscal year ending June 30, 2026. Early adoption is permitted on a prospective basis. We are currently evaluating the impact of this ASU on our annual income tax disclosures. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40)

Revenue from Contract with Customer [Abstract]
REVENUE	REVENUE Contract Balances The following table represents the opening and closing balances of accounts receivable, net, contract assets and contract liabilities as of the indicated dates. As of As of (Dollar amounts in thousands) December 31, 2024 June 30, 2024 $ Change % Change Accounts receivable, net $ 2,334,977 $ 1,833,041 $ 501,936 27 % Contract assets $ 82,292 $ 69,259 $ 13,033 19 % Contract liabilities $ 1,927,747 $ 1,782,242 $ 145,505 8 % 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 six months ended December 31, 2024 was mainly due to $64.0 million of revenue recognized for which the payment is subject to conditions other than passage of time, partially offset by $51.0 million of contract assets reclassified to accounts receivable, net, as our right to consideration for these contract assets became unconditional. Contract assets are included in other current assets on our Condensed Consolidated Balance Sheets. The change in contract liabilities during the six months ended December 31, 2024 was mainly due to the recognition of revenue of $1.14 billion that was included in contract liabilities as of June 30, 2024, largely offset by an increase in the value of products and services billed to customers for which control of the products and services has not transferred to the customers. Contract liabilities are included in other current liabilities and other non-current liabilities on our Condensed Consolidated Balance Sheets. Remaining Performance Obligations As of December 31, 2024, we had $9.14 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 $542.9 million as disclosed in Note 4 “Financial Statement Components” and excludes contract liabilities of $1.93 billion as disclosed above. We expect to recognize approximately 67% to 72% of these performance obligations as revenue in the next 12 months, 20% to 25% in the subsequent 12 months and the remainder thereafter, but this estimate is subject to constant change. After the 2024 BIS Rules and 2025 BIS Rules, defined below, were promulgated, we reduced our RPO by an aggregate of approximately $430 million because we are currently unable to ship the products ordered by affected customers without an export license, of which approximately 50% was included in the RPO expected to be recognized as revenue in the following 12 months, as disclosed in our quarterly report on Form 10-Q for the quarter ended September 30, 2024. The amount of our RPO and timing of revenue recognition of our RPO are evaluated quarterly and are largely driven by multiple variables, many of which are beyond our control, such as: changes in regulations, 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 and supply chain constraints. 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. The U.S. government has tightened export controls for commodities, software, and technology (collectively, “items”) destined to People’s Republic of China (“China”) over the past several years. In addition, in October 2022, the U.S. government's Bureau of Industry and Security (“BIS”) of the U.S. Department of Commerce (“Commerce”) issued regulations (the “2022 BIS Rules”) 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 China, and for the provision of support by U.S. Persons to certain advanced integrated circuit (“IC”) fabs located in China. The regulations impose export license requirements effectively on all KLA items 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. Companies were added to the U.S. Entity List, a list of parties that are generally ineligible to receive U.S.-regulated items without prior licensing from the BIS. In October 2023, the U.S. government issued additional regulations that went into effect in November 2023 (the “2023 BIS Rules”). 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 previous 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. In January 2024, KLA, among other companies, submitted comments to the government regarding these regulations. Furthermore, in December 2024 and January 2025, the BIS again issued incremental regulations (the “2024 BIS Rules” and the “2025 BIS Rules,” respectively) adding even more companies to the U.S. Entity List and revising the definition of advanced DRAM, further restricting our ability to provide certain items and services to facilities in China producing advanced DRAM ICs. The regulations are very complex. 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. There can be no assurance that export licenses applied for by either us or our customers, now or in the future, will be granted.

FAIR VALUE MEASUREMENTS

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 7 “Debt” to our Condensed Consolidated Financial Statements 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 and, for goodwill, also annually. 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. The types of instruments valued based on quoted market prices in active markets include 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 include 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. Financial assets (excluding cash held in operating accounts and time deposits) and liabilities measured at fair value on a recurring basis, as of the dates indicated below, were presented on our Condensed Consolidated Balance Sheets as follows: Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs As of December 31, 2024 (In thousands) Total (Level 1) (Level 2) Assets Cash equivalents: Corporate debt securities $ 3,631 $ — $ 3,631 Money market funds and other 1,215,402 1,215,402 — U.S. Treasury securities 19,962 — 19,962 Marketable securities: Corporate debt securities 873,071 — 873,071 Municipal securities 56,018 — 56,018 U.S. Government agency securities 92,663 92,663 — U.S. Treasury securities 701,153 599,116 102,037 Equity securities 15,938 15,938 — Total cash equivalents and marketable securities (1) 2,977,838 1,923,119 1,054,719 Other current assets: Derivative assets 34,598 — 34,598 Other non-current assets: Executive Deferred Savings Plan 320,295 276,125 44,170 Total financial assets (1) $ 3,332,731 $ 2,199,244 $ 1,133,487 Liabilities Derivative liabilities $ (14,401) $ — $ (14,401) Total financial liabilities $ (14,401) $ — $ (14,401) ________________ (1) Excludes cash of $537.4 million held in operating accounts and time deposits of $265.1 million (of which $61.8 million were cash equivalents) as of December 31, 2024.

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 December 31, 2024, we had 200 investments in a gross 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. 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 2025, in connection with our annual strategic planning process, we noted a continued deterioration of the long-term forecast for our Printed Circuit Board (“PCB”) business, which is part of our PCB and Component Inspection reportable segment. In addition, in the second quarter of fiscal 2025, we completed an internal reorganization affecting the composition of reporting units within our Specialty Semiconductor Process and PCB and Component Inspection reportable segments. The downward revision of financial outlook for PCB and the reorganization of reporting units triggered goodwill impairment tests. The following table presents changes in goodwill carrying value by reportable segment during the six months ended December 31, 2024: (In thousands) Semiconductor Process Control Specialty Semiconductor Process PCB and Component Inspection Total Balances as of June 30, 2024 $ 753,018 $ 681,858 $ 580,850 $ 2,015,726 Goodwill impairment — — (230,400) (230,400) Foreign currency adjustments (29) — — (29) Balances as of December 31, 2024 $ 752,989 $ 681,858 $ 350,450 $ 1,785,297 As a result of our quantitative assessment before reorganization, we recorded a total goodwill impairment charge of $230.4 million in the PCB reporting unit, which is part of the PCB and Component Inspection reportable segment, in the three months ended December 31, 2024. No goodwill impairment was identified in the Specialty Semiconductor Process reportable segment. We assessed for impairment subsequent to the reorganization and noted no impairment. The goodwill balances of our new reporting units after reorganization were allocated on a relative fair value basis. 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 the 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 based on a perpetual nominal growth rate, which is based on projected long-range inflation and long-term industry projections. The discount rates are based on the weighted average cost of capital of comparable peer companies adjusted for the company-specific risk. The market approach estimates the fair value of the reporting unit by utilizing the market comparable method, which is based on revenue and earnings multiples from comparable companies. There can be no assurance that these estimates and assumptions will prove to be an accurate prediction of the future, and a downward revision of these estimates and/or assumptions would decrease the fair value of our reporting units, which could result in additional impairment charges in the future. During the second quarter of fiscal 2024, we identified an impairment indicator within our PCB and Component Inspection reportable segment due to the deterioration in long-term forecast for the PCB and Display businesses. As a result of our quantitative assessment, we recorded a total goodwill impairment charge of $192.6 million in the three months ended December 31, 2023. The fair values of the relevant reporting units were determined using the same approach described above. As of June 30, 2024, Goodwill is net of accumulated impairment losses of $277.6 million, $144.2 million and $70.5 million in the Semiconductor Process Control, Specialty Semiconductor Process and PCB and Component Inspection reportable segments, respectively. As of December 31, 2024, following the internal reorganization noted above, Goodwill is net of accumulated impairment losses of $277.6 million and $70.5 million in the Semiconductor Process Control and PCB and Component Inspection reportable segments, respectively. Purchased Intangible Assets The components of purchased intangible assets as of the dates indicated below were as follows: (In thousands) As of December 31, 2024 As of June 30, 2024 Category Gross Accumulated Net Gross Accumulated Net Existing technology $ 1,552,074 $ 1,138,143 $ 413,931 $ 1,552,074 $ 1,045,585 $ 506,489 Customer relationships 358,567 267,026 91,541 358,567 248,106 110,461 Trade name / Trademark 119,083 106,704 12,379 119,083 97,106 21,977 Order backlog and other 87,536 82,989 4,547 83,336 82,740 596 Intangible assets subject to amortization 2,117,260 1,594,862 522,398 2,113,060 1,473,537 639,523 In-process research and development 46,074 19,827 26,247 46,074 16,833 29,241 Total $ 2,163,334 $ 1,614,689 $ 548,645 $ 2,159,134 $ 1,490,370 $ 668,764 Purchased intangible assets are reviewed for impairment whenever events or changes in circumstances indicate that the carrying amount of an asset or asset group may not be fully recoverable. We identified an impairment indicator for the long-lived assets in our PCB and Component Inspection reportable segment during the second quarter of fiscal 2025 due to the downward revision of financial outlook for the PCB business as noted above. The internal reorganization described above was also considered a trigger for impairment analysis of the long-lived assets of the Specialty Semiconductor Process and PCB and Component Inspection reportable segments. In connection with the evaluation of goodwill impairment, we assessed tangible and intangible assets for impairment prior to performing the goodwill impairment tests. We first performed a recoverability test for each affected asset group by comparing projected undiscounted cash flows from the use and eventual disposition of each asset group to its carrying value. The tests indicated that the undiscounted cash flows of all asset groups in the Specialty Semiconductor Process reportable segment were sufficient to recover the carrying value of the asset groups. However, the tests indicated that the undiscounted cash flows were not sufficient to recover the carrying value of the asset groups in the PCB and Component Inspection reportable segment. 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. Determining the fair value involved the use of significant estimates and assumptions, including revenue forecasts, terminal growth rate, tax rate and a weighted average cost of capital adjusted for company-specific risk. We recorded a total purchased intangible assets impairment charge $8.7 million for the three months ended December 31, 2024. No impairment was identified for other long-lived asset groups of the Company in the three months ended December 31, 2024. As part of the evaluation of goodwill impairment in the PCB and Component Inspection reportable segment in the second quarter of fiscal 2024 noted above, the Company assessed long-lived assets for impairment prior to performing the goodwill impairment test. As a result, we recorded a total purchased intangible asset impairment charge $26.4 million for the three months ended December 31, 2023. Total impairment charges for goodwill and purchased intangible assets of $239.1 million and $219.0 million were recognized as separate charges and included in income (loss) from operations in the three months ended December 31, 2024 and December 31, 2023, respectively. Amortization expense for purchased intangible assets was $58.9 million and $115.6 million for the three and six months ended December 31, 2024, respectively, and $59.4 million and $122.7 million for the three and six months ended December 31, 2023, respectively. Based on the purchased intangible assets gross carrying amount recorded as of December 31, 2024, the remaining estimated annual amortization expense is expected to be as follows: Fiscal year ending June 30: Amortization (In thousands) 2025 (remaining six months) $ 104,749 2026 195,762 2027 123,250 2028 48,016 2029 35,130 2030 and thereafter 15,491 Total $ 522,398

The net proceeds were used for general corporate purposes, including repayment of outstanding indebtedness at or prior to maturity. Prior to February 2024, the following aggregate principal amounts of senior, unsecured long-term notes were issued in the following periods: $3.00 billion in June 2022 (the “2022 Senior Notes”), $750.0 million in February 2020 (the “2020 Senior Notes”), $1.20 billion in March 2019 (the “2019 Senior Notes”) and $2.50 billion in November 2014 (the “2014 Senior Notes”). These, along with the 2024 Senior Notes, are collectively referred to as the “Senior Notes.” In November 2024, we repaid $750.0 million of the 2014 Senior Notes that were due on November 1, 2024. 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 Senior Notes rank senior in right of payment to all of the Issuer's future subordinated indebtedness, equally in right of payment with all of the Issuer's existing and future unsecured and unsubordinated indebtedness, are effectively subordinated in right of payment to all of the Issuer's future secured indebtedness to the extent of the collateral securing such indebtedness and structurally subordinated in right of payment to all existing and future indebtedness and other liabilities of the Issuer's subsidiaries. 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. Based on the trading prices of the Senior Notes on the applicable dates, the fair value of the Senior Notes as of December 31, 2024 and June 30, 2024 was $5.46 billion and $6.26 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 December 31, 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 dated June 8, 2022 (“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 December 31, 2024, we had no outstanding 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 we 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 Rate (“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, if 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 (“KPI”) related to greenhouse gas emissions and renewable electricity usage. Our performance against these KPIs in calendar year 2023 resulted in reductions to the fees associated with our Revolving Credit Facility. As of December 31, 2024, we elected to pay interest on borrowings under the Revolving Credit Facility at the applicable Adjusted Term SOFR rate plus a spread of 82.5 bps and the applicable commitment fee on the daily undrawn balance of the Revolving Credit Facility was 5.5 bps. Under the Credit Agreement, the maximum leverage ratio 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 December 31, 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 December 31, 2024. For additional details, refer to Note 8 “Debt” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended 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, research and development (“R&D”), manufacturing, and storage and distribution. Our finance leases are not significant. 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 $11.9 million and $25.0 million for the three and six months ended December 31, 2024, respectively and $12.9 million and $25.2 million for the three and six months ended December 31, 2023, respectively. Expenses related to short-term leases, which were not recorded on the Condensed Consolidated Balance Sheets, were not material for the three and six months ended December 31, 2024 and 2023. As of December 31, 2024 and June 30, 2024, the weighted-average remaining lease term was 6.3 and 6.7 years, respectively, and the weighted-average discount rate for operating leases was 4.30% as of both December 31, 2024 and June 30, 2024. Supplemental cash flow information related to leases was as follows: Six Months Ended December 31, In thousands 2024 2023 Operating cash outflows from operating leases $ 21,258 $ 20,504 Right of use assets obtained in exchange for new operating lease liabilities $ 22,051 $ 38,513 Maturities of lease liabilities as of December 31, 2024 were as follows: Fiscal Year Ending June 30: (In thousands) 2025 (remaining six months) $ 25,517 2026 46,172 2027 35,043 2028 23,828 2029 20,644 2030 and thereafter 70,436 Total lease payments 221,640 Less imputed interest (31,414) Total $ 190,226

Share-Based Payment Arrangement [Abstract]
EQUITY AND LONG-TERM INCENTIVE COMPENSATION PLANS	EQUITY AND LONG-TERM INCENTIVE COMPENSATION PLANS 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 December 31, 2024, 10.0 million shares remained available for issuance under our 2023 Plan. In addition, we have an Employee Stock Purchase Plan (“ESPP”), which enables eligible employees to purchase our common stock. We also offer a cash-based long-term incentive program (“Cash LTI”) to eligible employees. For details of the 2023 Plan, ESPP and Cash LTI plans, refer to Note 10 “Equity, Long-Term Incentive Compensation Plans and Non-Controlling Interest” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024.

(2) Includes RSUs granted to senior management during the six months ended December 31, 2024 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”). This line item includes all such performance-based RSUs granted during the six months ended December 31, 2024 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 for the six months ended December 31, 2024 reflect the application of the 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 six months ended December 31, 2024. 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.

STOCK REPURCHASE PROGRAM

STOCK REPURCHASE PROGRAM	6 Months Ended

Equity [Abstract]
STOCK REPURCHASE PROGRAM	STOCK REPURCHASE PROGRAM Our Board of Directors has authorized a program that permits us to repurchase our common stock, including an increase in the authorized repurchase amount of $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. 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, the Inflation Reduction Act of 2022 introduced a 1% excise tax imposed on certain stock repurchases made after December 31, 2022 by publicly traded companies. 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 December 31, 2024, an aggregate of $963.2 million of authorization was available for repurchase under the stock repurchase program. Share repurchases for the indicated periods (based on the trade date of the applicable repurchase) were as follows: Three Months Ended December 31, Six Months Ended December 31, (In thousands) 2024 2023 2024 2023 Number of shares of common stock repurchased 979 848 1,719 1,804 Total cost of repurchases $ 655,973 $ 441,563 $ 1,226,909 $ 900,656

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 shares of common stock outstanding during the period. Diluted net income per share is calculated by using the weighted-average number of shares of common stock 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. The following table sets forth the computation of basic and diluted net income per share: (In thousands, except per share amounts) Three Months Ended December 31, Six Months Ended December 31, 2024 2023 2024 2023 Numerator: Net income $ 824,527 $ 582,534 $ 1,770,378 $ 1,323,909 Denominator: Weighted-average shares - basic, excluding unvested RSUs 133,327 135,539 133,730 135,976 Effect of dilutive RSUs and options 599 715 685 708 Weighted-average shares - diluted 133,926 136,254 134,415 136,684 Basic net income per share $ 6.18 $ 4.30 $ 13.24 $ 9.74 Diluted net income per share $ 6.16 $ 4.28 $ 13.17 $ 9.69 Anti-dilutive securities excluded from the computation of diluted net income per share 145 — 36 —

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 United States federal income tax examination for the fiscal years ended June 30, 2018, June 30, 2019 and June 30, 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. After the income tax examination in Israel described in Note 14 “Income Taxes” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024, we received a tax assessment for calendar year ended December 31, 2019 to fiscal year ended June 30, 2022. The assessment will be appealed. We believe our current unrecognized tax benefits are sufficient. It is possible that certain examinations may be concluded in the next 12 months. The timing and resolution of income tax examinations are uncertain. 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 In December 2021, the Organization for Economic Co-operation and Development’s (“OECD”) Inclusive Framework on Base Erosion and Profit Shifting (“BEPS”) released Global Anti-Base Erosion (“GloBE”) rules under Pillar Two. For the countries that have enacted legislation to adopt the Pillar Two GloBE rules, the provision requiring a 15% minimum effective tax rate on income earned in the respective countries is effective for us beginning in our current fiscal year. There was no material impact to our financial statements from this Pillar Two provision during the three and six months ended December 31, 2024. In November 2024, Singapore adopted the Pillar Two GloBE rules under the Multinational Enterprise (“Minimum Tax”) Act (“MMT Act”), which includes a domestic minimum tax of 15% for financial years beginning on or after January 1, 2025. We earn significant profits and currently benefit from tax incentives in Singapore, so it is likely the MMT Act will neutralize our current tax incentives when it is effective for us beginning in our fiscal year ending June 30, 2026. We will continue to evaluate the impact of the MMT Act to our future financial statements. The Pillar Two GloBE rules are deemed an alternative minimum tax so we will not recognize any deferred taxes for the estimated effects of the future minimum tax under current U.S. GAAP.

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 Condensed 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 Condensed 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 letters of credit (“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: Three Months Ended December 31, Six Months Ended December 31, (In thousands) 2024 2023 2024 2023 Receivables sold under factoring agreements $ 38,246 $ 49,072 $ 83,705 $ 94,679 Proceeds from sales of LC $ 33,359 $ 13,900 $ 35,337 $ 13,900 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. KLA may continue servicing the receivables that are sold. 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 approximately $2.31 billion as of December 31, 2024, a majority of which are 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 December 31, 2024, we have committed $136.2 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 $107.1 million, of which $71.9 million had been issued as of December 31, 2024, primarily to fund guarantees to customs authorities for value-added tax and other operating requirements of our consolidated subsidiaries worldwide. 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 Condensed 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 we 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 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 Condensed 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 forward contracts, generally to hedge the benchmark interest rate on portions of our Senior Notes prior to issuance (“Rate Lock Agreements”). 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. We recognized net gains of $0.8 million and $1.8 million in the three and six months ended December 31, 2024, respectively, for the amortization of the net of the Rate Lock Agreements that had been recognized in AOCI, which decreased the interest expense on a net basis. We recognized net gains of $0.9 million and $1.9 million in the three and six months ended December 31, 2023, respectively, for the amortization of the net of the Rate Lock Agreements that had been recognized in AOCI, which decreased the interest expense on a net basis. As of December 31, 2024, the aggregate unamortized portion of the fair value of the forward contracts for the Rate Lock Agreements was a $45.9 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 differences between changes 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.

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. Our operating segments are aggregated into reportable segments based on several factors including, but not limited to, customer base, homogeneity of products, technology, delivery channels and similar economic characteristics. We have three reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection. 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. 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 microelectromechanical systems (“MEMS”), radio frequency (“RF”) communication chips and power semiconductors for automotive and industrial applications. PCB and Component Inspection The PCB and Component Inspection segment enables electronic device manufacturers to inspect, test and measure PCBs, flat panel displays 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. In March 2024, we made the decision to exit the Display business by announcing we would end manufacturing of most Display products but 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: Three Months Ended December 31, Six Months Ended December 31, (In thousands) 2024 2023 2024 2023 Semiconductor Process Control: Revenues $ 2,755,743 $ 2,194,079 $ 5,330,894 $ 4,329,557 Segment gross profit 1,763,077 1,418,339 3,379,859 2,804,868 Specialty Semiconductor Process: Revenues 160,407 150,065 288,741 276,784 Segment gross profit 81,122 81,278 145,616 150,579 PCB and Component Inspection: Revenues 161,080 143,032 299,063 279,075 Segment gross profit 55,526 57,165 113,063 96,985 Totals: Revenues for reportable segments $ 3,077,230 $ 2,487,176 $ 5,918,698 $ 4,885,416 Segment gross profit $ 1,899,725 $ 1,556,782 $ 3,638,538 $ 3,052,432 The following table reconciles total reportable segment revenues to total revenues for the indicated periods: Three Months Ended December 31, Six Months Ended December 31, (In thousands) 2024 2023 2024 2023 Total revenues for reportable segments $ 3,077,230 $ 2,487,176 $ 5,918,698 $ 4,885,416 Corporate allocations and effects of changes in foreign currency exchange rates (379) (450) (306) (1,734) Total revenues $ 3,076,851 $ 2,486,726 $ 5,918,392 $ 4,883,682 The following table reconciles total segment gross profit to income before income taxes for the indicated periods: Three Months Ended December 31, Six Months Ended December 31, (In thousands) 2024 2023 2024 2023 Total segment gross profit $ 1,899,725 $ 1,556,782 $ 3,638,538 $ 3,052,432 Acquisition-related charges, corporate allocations and effects of changes in foreign currency exchange rates (1) 44,335 46,802 89,038 92,387 R&D 346,157 320,418 669,302 631,632 SG&A 267,081 237,244 518,123 476,889 Impairment of goodwill and purchased intangible assets 239,100 219,000 239,100 219,000 Interest expense 74,981 74,202 157,152 148,436 Other expense (income), net (44,458) (32,154) (85,393) (58,893) Income before income taxes $ 972,529 $ 691,270 $ 2,051,216 $ 1,542,981 __________________ (1) Acquisition-related charges primarily include amortization of intangible assets and other acquisition-related costs classified or presented as part of costs of revenues.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Basis of Presentation	Basis of Presentation. For purposes of this report, “KLA,” the “Company,” “we,” “our,” “us” or similar references mean KLA Corporation and its majority-owned subsidiaries unless the context requires otherwise. The Condensed Consolidated Financial Statements have been prepared by us pursuant to the rules and regulations of the U.S. Securities and Exchange Commission. Certain information and footnote disclosures normally included in financial statements prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) have been condensed or omitted pursuant to such rules and regulations. The unaudited interim Condensed Consolidated Financial Statements do not include all of the information and footnotes required by GAAP for audited financial statements. The balance sheet as of June 30, 2024 was derived from the Company’s audited Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024, but does not include all disclosures required by GAAP for audited financial statements. The unaudited interim Condensed Consolidated Financial Statements reflect all adjustments (consisting only of normal, recurring adjustments) necessary for a fair statement of the financial position, results of operations, comprehensive income, stockholders’ equity and cash flows for the periods indicated. These Condensed Consolidated Financial Statements and notes, however, should be read in conjunction with Item 8 “Financial Statements and Supplementary Data” included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2024. The Condensed Consolidated Financial Statements include the accounts of KLA and its majority-owned subsidiaries. All significant intercompany balances and transactions have been eliminated. The results of operations for the three and six months ended December 31, 2024 are not necessarily indicative of the results that may be expected for any other interim period or for the full fiscal year ending June 30, 2025.
Management Estimates	Management Estimates. The preparation of the Condensed Consolidated Financial Statements in conformity with GAAP 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 dates of the Condensed Consolidated Financial Statements and the reported amounts of revenues and expenses during the reporting periods. Actual results could differ from those estimates.
Reclassifications	Reclassifications . The Company has reclassified certain prior period balances to conform to the current year presentation. These reclassifications did not impact any prior amounts of reported total assets, total liabilities, stockholders’ equity, results of operations or cash flows.
Government Incentives	Government Incentives. We occasionally receive incentives from governmental entities related to capital expenditures, expenses and other activities, primarily in the form of cash grants and tax credits. Government assistance is recognized when there is reasonable assurance that (1) the Company will comply with relevant conditions; and (2) the assistance will be received. Government incentives related to the acquisition or construction of property, plant and equipment are recognized as a reduction in the carrying amounts of the related assets and reduce depreciation expense over the useful lives of the assets. Incentives related to specific operating activities are offset against the related expense in the period the expense is incurred.
Collaborative Arrangements	Collaborative Arrangements. We assess joint development arrangements to determine whether they are in the scope of Accounting Standards Codification (“ASC”) 808, Collaborative Arrangements.

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 will adopt this update for our annual report for the fiscal year ending June 30, 2025. In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740), Improvements to Income Tax Disclosures . The new guidance requires enhanced disclosures about income tax expenses. This standard update is effective for our annual reports beginning in the fiscal year ending June 30, 2026. Early adoption is permitted on a prospective basis. We are currently evaluating the impact of this ASU on our annual income tax disclosures.

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 7 “Debt” to our Condensed Consolidated Financial Statements 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 and, for goodwill, also annually.
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. The types of instruments valued based on quoted market prices in active markets include 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 include 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.
