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, 2023 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, 2023, 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, 2023. 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 nine months ended March 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, 2024. 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. 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, 2023. 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

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) March 31, 2024 June 30, 2023 $ Change % Change Accounts receivable, net $ 1,625,257 $ 1,753,361 $ (128,104) (7) % Contract assets $ 87,621 $ 117,137 $ (29,516) (25) % Contract liabilities $ 1,716,767 $ 1,245,007 $ 471,760 38 % Our payment terms and conditions vary by contract type, although the terms generally include a requirement of payment of 70% to 90% of total contract consideration within 30 to 60 days of product shipment, with the remainder payable within 30 days of acceptance. The change in contract assets during the nine months ended March 31, 2024 was mainly due to $98.5 million of contract assets reclassified to accounts receivable, net, as our right to consideration for these contract assets became unconditional, partially offset by $69.2 million of revenue recognized for which the payment is subject to conditions other than passage of time. Contract assets are included in other current assets on our Condensed Consolidated Balance Sheets. The change in contract liabilities during the nine months ended March 31, 2024 was mainly due to 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, partially offset by recognition in revenue of $884.0 million that was included in contract liabilities as of June 30, 2023. Contract liabilities are included in current and non-current liabilities on our Condensed Consolidated Balance Sheets. Remaining Performance Obligations As of March 31, 2024, we had $9.90 billion of remaining performance obligations, 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 $677.0 million as disclosed in Note 4 “Financial Statement Components” and excludes contract liabilities of $1.72 billion as described above. We expect to recognize approximately 40% to 45% of these performance obligations as revenue beyond the next 12 months, but this estimate is subject to constant change. 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 integrated circuit (“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.

FAIR VALUE MEASUREMENTS

FAIR VALUE MEASUREMENTS	9 Months Ended
	Mar. 31, 2024
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” 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. 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 nine months ended March 31, 2024. 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. 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” to our Condensed Consolidated Financial Statements 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 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 Little or No Market Activity Inputs As of March 31, 2024 (In thousands) Total (Level 1) (Level 2) (Level 3) Assets Cash equivalents: Corporate debt securities $ 1,517 $ — $ 1,517 $ — Money market funds and other 1,091,385 1,091,385 — — U.S. Treasury securities 35,606 — 35,606 — Marketable securities: Corporate debt securities 765,619 — 765,619 — Municipal securities 40,127 — 40,127 — U.S. Government agency securities 93,208 93,208 — — U.S. Treasury securities 725,509 435,647 289,862 — Equity securities 29,260 29,260 — — Total cash equivalents and marketable securities (1) 2,782,231 1,649,500 1,132,731 — Other current assets: Derivative assets 35,838 — 35,838 — Other non-current assets: Executive Deferred Savings Plan 297,915 265,969 31,946 — Total financial assets (1) $ 3,115,984 $ 1,915,469 $ 1,200,515 $ — Liabilities Derivative liabilities $ (16,716) $ — $ (16,716) $ — Contingent consideration payable (67) — — (67) Total financial liabilities $ (16,783) $ — $ (16,716) $ (67) ________________ (1) Excludes cash of $457.6 million held in operating accounts and time deposits of $1.05 billion (of which $262.1 million were cash equivalents) as of March 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 March 31, 2024, we had 341 investments in a gross unrealized loss position.

Business Combination and Asset Acquisition [Abstract]
BUSINESS COMBINATIONS AND DISPOSITIONS	BUSINESS COMBINATIONS AND DISPOSITIONS Business Combinations On August 9, 2022, we acquired a privately held company, primarily to secure the supply of materials for existing products, for aggregate purchase consideration of $32.7 million, payable in cash. We allocated the purchase consideration as follows: $30.0 million to identifiable intangible assets, $2.3 million to net tangible assets, $6.5 million to deferred tax liabilities and $6.8 million to goodwill. The goodwill was assigned to the Wafer Inspection and Patterning reporting unit. The purchase consideration included a $3.7 million holdback to satisfy general warranties and representations that was paid in full in February 2024. We have included the financial results of the acquisition in our Condensed Consolidated Financial Statements from the acquisition date, and these results were not material to our Condensed Consolidated Financial Statements. The goodwill recorded as a result of the above acquisition was not deductible for tax purposes. As of March 31, 2024, we had $0.1 million contingent consideration recorded for completed acquisitions. Business Dispositions As of June 30, 2022, we owned approximately 94% of the outstanding equity interest in Orbograph Ltd. (“Orbograph”), 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 9, 2022, we acquired the non-controlling interest in Orbograph. On August 11, 2022, we sold our entire interest in Orbograph to a portfolio company of a private equity firm for total consideration of $110.0 million and net cash proceeds from the transaction of $75.4 million. We recognized a pre-tax gain from the sale of $29.7 million, which was recorded as part of other expense (income), net. Included in the sale were $26.5 million in tangible assets, $30.5 million in liabilities and $61.2 million in goodwill and intangible assets. For additional details of business combinations, refer to Note 6 “Business Combinations and Dispositions” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2023.

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. In testing goodwill for impairment, we utilize a qualitative assessment to evaluate whether it is more likely than not that the fair value of a reporting unit is less than its carrying amount. When performing the qualitative assessment, we consider the following factors: stock price or market capitalization, changes in the industry and competitive environment, budget-to-actual revenue and profitability performance from the prior year and projected revenue and profitability trends for future years at our reporting units. If our qualitative assessment indicates that goodwill impairment is more likely than not, we perform a quantitative assessment by comparing the carrying value to the fair value of the reporting units. If the fair value is determined to be less than the carrying value, the amount of impairment is computed as the excess of the carrying value over the estimated fair value, not to exceed the carrying value of goodwill. Any impairment charges could have a material adverse effect on our operating results and net asset value in the quarter in which we recognize the impairment charge. 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 (“Display”). 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 based on 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. The next annual goodwill impairment assessment by reporting unit is scheduled to be performed in the third quarter of the fiscal year ending June 30, 2025. During the second quarter of fiscal 2024, we noted a significant deterioration of the long-term forecast for our Printed Circuit Board (“PCB”) and 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 three months 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. The following table presents changes in goodwill carrying value by reporting unit during the nine months ended March 31, 2024: (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, 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 nine months ended March 31, 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 (19) — — — — — — (19) Balances as of March 31, 2024 Goodwill 1,004,681 25,908 826,037 — 567,275 70,474 13,575 $ 2,507,950 Accumulated impairment losses (277,570) — (144,179) — — (70,474) — (492,223) $ 727,111 $ 25,908 $ 681,858 $ — $ 567,275 $ — $ 13,575 $ 2,015,727 Purchased Intangible Assets The components of purchased intangible assets as of the dates indicated below were as follows: (In thousands) As of March 31, 2024 As of June 30, 2023 Category Range of Useful Lives (in years) Gross Accumulated Net Gross Accumulated Net Existing technology 4-8 $ 1,552,074 $ 999,639 $ 552,435 $ 1,536,826 $ 841,815 $ 695,011 Customer relationships 4-9 358,567 238,925 119,642 358,567 205,037 153,530 Trade name / Trademark 4-7 119,083 93,447 25,636 116,583 78,749 37,834 Order backlog and other <1-7 83,336 82,689 647 85,836 82,264 3,572 Intangible assets subject to amortization 2,113,060 1,414,700 698,360 2,097,812 1,207,865 889,947 In-process research and development 46,074 16,833 29,241 61,322 15,966 45,356 Total $ 2,159,134 $ 1,431,533 $ 727,601 $ 2,159,134 $ 1,223,831 $ 935,303 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. Impairment indicators primarily include declines in our operating cash flows from the use of these assets. As of March 31, 2024 , in connection with the Company's decision to exit the Display business, as described above, an immaterial amount of purchased intangible assets were abandoned. There were no other impairment indicators for purchased intangible assets in the three months ended March 31, 2024. 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 of $26.4 million. No impairment was identified for other long-lived assets in the three months ended December 31, 2023. Total impairment charges for goodwill and purchased intangible assets of $219.0 million were recognized during the three months ended December 31, 2023, as a separate charge and included in income (loss) from operations. Amortization expense for purchased intangible assets for the periods indicated below was as follows: Three Months Ended March 31, Nine Months Ended March 31, (In thousands) 2024 2023 2024 2023 Amortization expense - Costs of revenues $ 44,849 $ 45,446 $ 137,024 $ 135,958 Amortization expense - SG&A 12,916 19,656 43,411 59,912 Amortization expense - Research and development — 31 — 93 Total $ 57,765 $ 65,133 $ 180,435 $ 195,963 Based on the purchased intangible assets gross carrying amount recorded as of March 31, 2024, the remaining estimated annual amortization expense is expected to be as follows: Fiscal year ending June 30: Amortization (In thousands) 2024 (remaining three months) $ 58,837 2025 218,639 2026 197,846 2027 125,517 2028 48,849 2029 and thereafter 48,672 Total $ 698,360

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 Senior Notes due November 1, 2024 including associated redemption premiums, accrued interest and other fees and expenses. The transaction resulted in a pre-tax net loss on extinguishment of debt of $13.3 million for the three months ended September 30, 2022. The remainder of the net proceeds were used for share repurchases and for general corporate purposes. Prior to June 2022, the following aggregate principal amounts of senior, unsecured long-term notes were issued in the following periods: $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 and the 2022 Senior Notes, are collectively referred to as the “Senior Notes.” 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. Based on the trading prices of the Senior Notes on the applicable dates, the fair value of the Senior Notes as of March 31, 2024 and June 30, 2023 was $6.39 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 March 31, 2024, we were in compliance with all of our covenants under the Indenture associated with the Senior Notes. Revolving Credit Facility As of March 31, 2024, we have in place a renegotiated 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 March 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 2022 resulted in reductions to the fees associated with our Revolving Credit Facility. As of March 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 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 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 March 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 March 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, 2023.

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 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 29 years, including periods covered by options to extend the lease when it is reasonably certain that the option will be exercised. Lease expense was $13.3 million and $38.5 million for the three and nine months ended March 31, 2024, respectively and $10.1 million and $29.2 million for the three and nine months ended March 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 nine months ended March 31, 2024 and 2023. As of March 31, 2024 and June 30, 2023, the weighted-average remaining lease term was 6.8 and 6.7 years, respectively, and the weighted-average discount rate for operating leases was 4.24% and 3.36%, respectively.

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 March 31, 2024, 10.6 million shares remained available for issuance under our 2023 Plan. For details of the 2004 Plan, 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, 2023.

(2) Includes RSUs granted to senior management during the nine months ended March 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 nine months ended March 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 nine months ended March 31, 2024 reflects the application of the multiplier described above). 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 following table shows stock-based compensation expense for the indicated periods: Three Months Ended March 31, Nine Months Ended March 31, (In thousands) 2024 2023 2024 2023 Stock-based compensation expense by: Costs of revenues $ 9,803 $ 8,596 $ 25,554 $ 20,189 R&D 16,430 13,289 42,211 30,437 SG&A 30,449 26,245 86,309 70,891 Total stock-based compensation expense $ 56,682 $ 48,130 $ 154,074 $ 121,517 Stock-based compensation capitalized as inventory as of March 31, 2024 and June 30, 2023 was $21.4 million and $16.7 million, respectively.

The intrinsic value of outstanding RSUs as of March 31, 2024 was $1.04 billion. Cash-Based Long-Term Incentive Compensation We have adopted a cash-based long-term incentive (“Cash LTI”) program (“Cash LTI Plan”) for many of our employees as part of our employee compensation program. Executives and non-employee members of the Board of Directors do not participate in the Cash LTI Plan. During the nine months ended March 31, 2024 and 2023, we approved Cash LTI awards of $0.1 million and $0.2 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 Employee Stock Purchase Plan (“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, until otherwise amended, is equal to 85% of the lesser of (i) the fair market value of our common stock at the commencement of the applicable 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: Three Months Ended March 31, Nine Months Ended March 31, 2024 2023 2024 2023 Stock purchase plan: Expected stock price volatility 31.6 % 43.8 % 32.2 % 42.7 % Risk-free interest rate 5.5 % 3.9 % 5.3 % 2.5 % Dividend yield 1.0 % 1.4 % 1.1 % 1.6 % Expected life (in years) 0.5 0.5 0.5 0.5 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) Three Months Ended March 31, Nine Months Ended March 31, 2024 2023 2024 2023 Total cash received from employees for the issuance of shares under the ESPP $ — $ — $ 48,433 $ 33,793 Number of shares purchased by employees through the ESPP — — 118 134 Tax benefits realized by us in connection with the disqualifying dispositions of shares purchased under the ESPP $ 711 $ 616 $ 2,407 $ 1,540 Weighted-average fair value per share based on Black-Scholes model $ 131.15 $ 97.32 $ 125.17 $ 89.81 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 March 31, 2024, a total of 2.5 million shares were reserved and available for issuance under the ESPP. Quarterly Cash Dividends On March 1, 2024, we paid a quarterly cash dividend of $1.45 per share to stockholders of record as of the close of business on February 19, 2024. The total amount of regular quarterly cash dividends and dividend equivalents paid during the three months ended March 31, 2024 and 2023 was $197.2 million and $180.9 million, respectively. The total amount of regular quarterly cash dividends and dividend equivalents paid during the nine months ended March 31, 2024 and 2023 was $575.5 million and $553.0 million, respectively. The amount of accrued dividend equivalents payable for regular quarterly cash dividends on unvested RSUs with dividend equivalent rights as of March 31, 2024 and June 30, 2023 was $12.4 million and $12.2 million, respectively. These amounts will be paid upon vesting of the underlying RSUs. Non-Controlling Interest

STOCK REPURCHASE PROGRAM

STOCK REPURCHASE PROGRAM	9 Months Ended
	Mar. 31, 2024
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, as explained further in Note 13 “Income Taxes,” the Inflation Reduction Act of 2022 (“IRA”) introduced a 1% excise tax imposed on certain stock repurchases made after December 31, 2022 by publicly traded companies.

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 attributable to KLA: (In thousands, except per share amounts) Three Months Ended March 31, Nine Months Ended March 31, 2024 2023 2024 2023 Numerator: Net income attributable to KLA $ 601,541 $ 697,837 $ 1,925,450 $ 2,702,623 Denominator: Weighted-average shares - basic, excluding unvested RSUs 134,954 137,865 135,638 140,349 Effect of dilutive RSUs and options 902 780 790 724 Weighted-average shares - diluted 135,856 138,645 136,428 141,073 Basic net income per share attributable to KLA $ 4.46 $ 5.06 $ 14.20 $ 19.26 Diluted net income per share attributable to KLA $ 4.43 $ 5.03 $ 14.11 $ 19.16 Anti-dilutive securities excluded from the computation of diluted net income per share — 12 1 226

INCOME TAXES	INCOME TAXES The following table provides details of income taxes: Three Months Ended March 31, Nine Months Ended March 31, (Dollar amounts in thousands) 2024 2023 2024 2023 Income before income taxes $ 702,008 $ 800,683 $ 2,244,989 $ 3,013,684 Provision for income taxes $ 100,467 $ 102,846 $ 319,539 $ 310,987 Effective tax rate 14.3 % 12.8 % 14.2 % 10.3 % Our effective tax rate is lower than the U.S. federal statutory rate during the three months ended March 31, 2024 primarily due to the proportion of earnings generated in jurisdictions with tax rates lower than the U.S. statutory rate and the proportion of U.S. earnings eligible for the Foreign Derived Intangible Income deduction. Our effective tax rate is lower than the U.S. federal statutory rate during the nine months ended March 31, 2024 primarily due to the proportion of earnings generated in jurisdictions with tax rates lower than the U.S. statutory rate and the proportion of U.S. earnings eligible for the Foreign Derived Intangible Income deduction. 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 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, 2019. 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. 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 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 during the nine months ended March 31, 2024. President Biden also signed into law the IRA on August 16, 2022. The IRA has several new 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 the quarter ended September 30, 2023 and we are not expecting to have any tax impact from the CAMT for the fiscal year ending June 30, 2024. The IRA also introduced a 1% excise tax imposed on certain stock repurchases made after December 31, 2022 by publicly traded companies. We began recording the excise tax as part of the cost basis of treasury stock repurchased after December 31, 2022. Other than the AMIC, the CAMT 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 Condensed Consolidated Financial Statements including our future cash flows.

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 March 31, Nine Months Ended March 31, (In thousands) 2024 2023 2024 2023 Receivables sold under factoring agreements $ 85,541 $ 107,140 $ 180,220 $ 288,599 Proceeds from sales of LC $ 8,342 $ — $ 22,242 $ 69,247 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 approximately $2.1 billion as of March 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 March 31, 2024, we have committed $163.3 million for future payment obligations under our Cash LTI Plan. The calculation of compensation expense related to the Cash LTI Plan includes estimated forfeiture rate assumptions. 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 $83.1 million, of which $48.6 million had been issued as of March 31, 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, our 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 HEDG

DERIVATIVE INSTRUMENTS AND HEDGING ACTIVITIES	9 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 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 $0.9 million and $2.8 million in the three and nine months ended March 31, 2024, respectively, and net gains of $0.9 million and $2.8 million in the three and nine months ended March 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 March 31, 2024, the aggregate unamortized portion of the fair value of the forward contracts for the Rate Lock Agreements was a $48.7 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 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 AND GEOGRAPHI

SEGMENT REPORTING AND GEOGRAPHIC INFORMATION	9 Months Ended
	Mar. 31, 2024
Segment Reporting [Abstract]
SEGMENT REPORTING AND GEOGRAPHIC INFORMATION	SEGMENT REPORTING AND GEOGRAPHIC INFORMATION Accounting Standards Codification 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, Display 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 microelectromechanical systems (“MEMS”), radio frequency (“RF”) communication chips and power semiconductors for automotive and industrial applications. This reportable segment is comprised of one operating segment. PCB, Display and Component Inspection The PCB, Display 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. This reportable segment is comprised of two operating segments, PCB and Display and Component Inspection. 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.

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, 2023 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, 2023, 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, 2023. 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 nine months ended March 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, 2024.
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.
Reclassification	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.
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 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” 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.
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 nine months ended March 31, 2024. 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.
