Consolidated Financial Statements (Unaudited) NOTE 1 – BASIS OF PRESENTATION Basis of Presentation. For purposes of this report, “KLA,” “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, 2025 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, 2025, 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, 2025. 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, 2025 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, 2026. 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 change, there have been no 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, 2025. Change in Annual Impairment Testing Date . During the second quarter of fiscal 2026, the Company changed the annual goodwill impairment testing date for all reporting units from February 28 to December 31 to better align with the timing of our budgeting and strategic planning process. We believe that the change in our annual impairment test date is preferable as it allows us to evaluate any potential impact strategic decisions may have on the recoverability of goodwill as those decisions are reached. This will also enable us to use the most current information available in the assessment process. The change in the annual impairment testing date did not delay, accelerate or avoid an impairment charge. For additional details, refer to Note 6 “Goodwill and Purchased Intangible Assets” to our Condensed Consolidated Financial Statements. Recent Accounting Pronouncements Recently Adopted 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 ended June 30, 2025, and interim period reports beginning in the first quarter of the fiscal year ending June 30, 2026. We adopted ASU 2023-07 starting with our annual report for the fiscal year ended June 30, 2025, for annual reporting and from July 1, 2025, for interim periods on a retrospective basis. 8 Table of Contents In September 2025, the FASB issued ASU 2025-06, Intangibles - Goodwill and Other - Internal-Use Software (Subtopic 350-40): Targeted Improvements to the Accounting for Internal-Use Software. The new guidance removes all references to prescriptive and sequential software development stages or project stages throughout Subtopic 350-40. Therefore, an entity is required to start capitalizing software costs when management has authorized and committed to funding the software project and it is probable that the project will be completed, and the software will be used to perform the function intended. The standard update is effective for our annual and interim reports beginning in the first quarter of our fiscal year ending June 30, 2028. Early adoption is permitted as of the beginning of an annual reporting period. We adopted ASU 2025-06 for our first quarter of the fiscal year ending June 30, 2026 using a prospective transition approach, and the effect was immaterial to our Consolidated Financial Statements. Updates Not Yet Effective 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. The amendments in this ASU will be applied on a prospective basis. Adoption of this new guidance will result in expanded disclosures in the Notes to the Consolidated Financial Statements. In November 2024, the FASB issued ASU 2024-03, Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses . The new guidance requires enhanced disclosures about certain expenses in the notes to the financial statements to provide enhanced transparency into the expense captions presented on the face of the income statement. In 2025, the FASB issued ASU 2025-01 which clarifies the effective date for entities that do not have an annual reporting period that ends on December 31st. The Company is required to adopt this standard for our annual reports beginning in the fiscal year ending June 30, 2028, and interim period reports beginning in the first quarter of the fiscal year ending June 30, 2029. Early adoption is permitted. The amendments in this ASU should be applied either on a prospective or retrospective basis. We are currently evaluating the impact of this ASU on our disclosures. In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (Topic 326), Measurement of Credit Losses for Accounts Receivable and Contract Assets. The new guidance allows companies to apply a practical expedient when estimating credit losses on current accounts receivable and contract assets. The standard update is effective for our annual and interim reports beginning in the first quarter of our fiscal year ending June 30, 2027. Early adoption is permitted for periods in which financial statements have not yet been issued or made ready for issuance. The amendments in this ASU should be applied on a prospective basis. We are currently evaluating the impact of adopting this guidance on our Consolidated Financial Statements. In December 2025, the FASB issued ASU 2025-10, Government Grants (Topic 832): Accounting for Government Grants Received by Business Entities. The new guidance establishes the accounting for a government grant received by a business entity, including guidance for a grant related to an asset and a grant related to income. The new guidance also requires disclosures, including the nature of the government grant received, the accounting policies used to account for the grant, and significant terms and conditions of the grant unless legally prohibited from being disclosed. The standard update is effective for our annual and interim reports beginning in the fiscal year ending June 30, 2030. Early adoption is permitted in both interim and annual reporting periods in which the financial statements have not yet been issued or made available for issuance. If adopted in an interim reporting period, it must be adopted as of the beginning of the annual reporting period that includes that interim reporting period. The amendments in this ASU should be applied using a modified prospective, modified retrospective, or retrospective approach. We are currently evaluating the impact of this guidance on our Consolidated Financial Statements. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements. The new guidance clarifies interim disclosure requirements and the applicability of Topic 270. The standard update is effective for our annual and interim reports beginning in the fiscal year ending June 30, 2029. Early adoption is permitted. The amendments in this ASU can be applied either prospectively or retrospectively to any or all periods presented in the financial statements. We are currently evaluating the impact of this guidance on our interim reporting. In December 2025, the FASB issued ASU 2025-12, Codification Improvements . The new guidance adds clarification, corrects errors, or makes minor improvements. The standard update is effective for our annual and interim reports beginning in the fiscal year ending June 30, 2028. Early adoption is permitted. The amendments in this ASU can be applied either prospectively or retrospectively to the beginning of the earliest period presented in the financial statements. We are currently evaluating the impact of this guidance on our on our Consolidated Financial Statements. 9 Table of Contents NOTE 2 – REVENUE 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, 2025 June 30, 2025 $ Change % Change Accounts receivable, net $ 2,073,581 $ 2,263,915 $ ( 190,334 ) ( 8 ) % Contract assets $ 93,117 $ 105,081 $ ( 11,964 ) ( 11 ) % Contract liabilities $ 1,727,891 $ 1,713,689 $ 14,202 1 % 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, 2025 was mainly due to $ 84.5 million of contract assets reclassified to accounts receivable, net, as our right to consideration for these contract assets became unconditional, partially offset by $ 72.7 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 six months ended December 31, 2025 was mainly due 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, largely offset by the recognition as revenue of $ 1.04 billion that was included in contract liabilities as of June 30, 2025. Contract liabilities are included in current liabilities and non-current liabilities, classified as deferred system revenue or deferred service revenue, on our Condensed Consolidated Balance Sheets. The following table represents the transaction price for contracts that have not yet been recognized as revenue as of December 31, 2025, which equals our contract liabilities, and when the Company expects to recognize the amounts as revenue: (Dollar amounts in thousands) Less than 12 months 12 to 24 months 24 months or greater Total Contract liabilities $ 1,457,342 $ 183,822 $ 86,727 $ 1,727,891 NOTE 3 – 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 recorded at fair value only if an impairment is recognized in the current period. We assess for impairment whenever events or changes in circumstances indicate that the carrying value of an asset may not be recoverable. For goodwill, we assess for impairment 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. 10 Table of Contents 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. 11 Table of Contents 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, 2025 (In thousands) Total (Level 1) (Level 2) Assets Cash equivalents: Corporate debt securities $ 11,517 $ — $ 11,517 Money market funds and other 2,029,446 2,029,446 — U.S. Treasury securities 2,993 — 2,993 Marketable securities: Corporate debt securities 1,123,698 — 1,123,698 Municipal securities 38,236 — 38,236 U.S. Government agency securities 114,233 114,233 — U.S. Treasury securities 1,161,326 1,116,331 44,995 Equity securities 16,874 16,874 — Total cash equivalents and marketable securities (1) 4,498,323 3,276,884 1,221,439 Other current assets: Derivative assets 52,505 — 52,505 Other non-current assets: Executive Deferred Savings Plan 369,933 278,880 91,053 Total financial assets (1) $ 4,920,761 $ 3,555,764 $ 1,364,997 Liabilities Derivative liabilities $ ( 8,219 ) $ — $ ( 8,219 ) Total financial liabilities $ ( 8,219 ) $ — $ ( 8,219 ) ________________ (1) Excludes cash of $ 307.3 million held in operating accounts and time deposits of $ 401.9 million (of which $ 100.9 million were cash equivalents) as of December 31, 2025. 12 Table of Contents Quoted Prices in Active Markets for Identical Assets Significant Other Observable Inputs As of June 30, 2025 (In thousands) Total (Level 1) (Level 2) Assets Cash equivalents: Municipal securities $ 6,120 $ — $ 6,120 Corporate debt securities 1,498 — 1,498 Money market funds and other 1,531,022 1,531,022 — U.S. Government agency securities 9,955 — 9,955 U.S. Treasury securities 9,981 — 9,981 Marketable securities: Corporate debt securities 960,148 — 960,148 Municipal securities 51,453 — 51,453 U.S. Government agency securities 106,881 106,881 — U.S. Treasury securities 877,578 802,682 74,896 Equity securities 23,962 23,962 — Total cash equivalents and marketable securities (1) 3,578,598 2,464,547 1,114,051 Other current assets: Derivative assets 59,503 — 59,503 Other non-current assets: Executive Deferred Savings Plan 349,530 336,090 13,440 Total financial assets (1) $ 3,987,631 $ 2,800,637 $ 1,186,994 Liabilities Derivative liabilities $ ( 28,615 ) $ — $ ( 28,615 ) Total financial liabilities $ ( 28,615 ) $ — $ ( 28,615 ) ________________ (1) Excludes cash of $ 437.8 million held in operating accounts and time deposits of $ 478.2 million (of which $ 82.5 million were cash equivalents) as of June 30, 2025.

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, 2025, we had 43 investments in a gross unrealized loss position. The following table summarizes the fair value and gross unrealized losses of our investments that were in an unrealized loss position as of the dates indicated below.

Realized gains and losses on available-for-sale securities for the three and six months ended December 31, 2025 and 2024 were immaterial. The costs for our equity marketable securities were $ 22.9 million as of both December 31, 2025, and June 30, 2025. Unrealized gains and losses for our equity marketable securities for the three and six months ended December 31, 2025 and 2024 were immaterial. NOTE 6 – 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. The following table presents changes in goodwill carrying value by reportable segment during the six months ended December 31, 2025: (In thousands) Semiconductor Process Control Specialty Semiconductor Process Printed Circuit Board (“PCB”) and Component Inspection Total Balances as of June 30, 2025 $ 759,885 $ 681,858 $ 350,450 $ 1,792,193 Foreign currency adjustments 82 ( 586 ) ( 1,092 ) ( 1,596 ) Balances as of December 31, 2025 $ 759,967 $ 681,272 $ 349,358 $ 1,790,597 As of December 31, 2025, and June 30, 2025, 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. Goodwill is not subject to amortization but is tested for impairment annually, 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. During the second quarter of fiscal 2026, the Company changed the annual goodwill impairment testing date for all reporting units from February 28 to December 31 to better align with the timing of our budgeting and strategic planning process. We believe this change is preferable because it allows us to evaluate any potential impact strategic decisions may have on the recoverability of goodwill as those decisions are reached. This will also enable us to use the most current information available in the assessment process. The change in the measurement date did not delay, accelerate or avoid recognition of an impairment charge. Each quarter the Company evaluates impairment indicators to determine whether a triggering event has occurred which would warrant a quantitative assessment to determine whether there has been an impairment. We have applied this change on a prospective basis for the fiscal year ending June 30, 2026 since the impact is not material to our financial statements. We performed the required annual goodwill impairment testing for all reportable segments as of December 31, 2025, and concluded that goodwill was not impaired. As a result of our qualitative assessment, we determined that it was not necessary to perform the quantitative assessment. 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 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. As a result of our quantitative assessment before reorganization, we recorded a total goodwill impairment charge of $ 230.4 million in the former PCB reporting unit, which was part of the PCB and Component Inspection reportable 17 Table of Contents segment, in the second quarter of fiscal 2025. 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 weighting of 75 percent and 25 percent, respectively. The income approach is estimated through discounted cash flow analysis. This valuation technique requires us to use significant estimates and assumptions, including long-term growth rates, discount rates and other inputs. 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. Purchased Intangible Assets Changes in the gross carrying amount of intangible assets result from changes in foreign currency exchange rates and acquisitions. The components of purchased intangible assets as of the dates indicated below were as follows: (In thousands) As of December 31, 2025 As of June 30, 2025 Category Gross Carrying Amount Accumulated Amortization and Impairment Net Amount Gross Carrying Amount Accumulated Amortization and Impairment Net Amount Existing technology $ 1,556,782 $ 1,298,518 $ 258,264 $ 1,555,688 $ 1,222,520 $ 333,168 Customer relationships 358,499 301,549 56,950 359,555 285,274 74,281 Trade name / Trademark 119,416 118,019 1,397 119,409 113,210 6,199 Order backlog and other 91,352 84,992 6,360 89,309 84,419 4,890 Intangible assets subject to amortization 2,126,049 1,803,078 322,971 2,123,961 1,705,423 418,538 In-process research and development 44,874 19,827 25,047 46,074 19,827 26,247 Total $ 2,170,923 $ 1,822,905 $ 348,018 $ 2,170,035 $ 1,725,250 $ 444,785 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. If impairment indicators are present, we are required to perform a recoverability test by comparing the sum of the estimated undiscounted future cash flows attributable to these long-lived assets to their carrying value. As of December 31, 2025, there were no impairment indicators for purchased intangible assets. In connection with the evaluation of the goodwill impairment in the PCB and Component Inspection reportable segment during the second quarter of fiscal 2025, due to the continued deterioration of financial outlook for the businesses and internal reorganization both 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 Component Inspection reportable segment 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 $ 8.7 million. No impairment was identified for other long-lived assets in the second quarter of fiscal 2025. Total impairment charges for goodwill and purchased intangible assets of $ 239.1 million were recognized as separate charges and included in income (loss) from operations in the three months ended December 31, 2024. Amortization expense for purchased intangible assets was $ 49.3 million and $ 98.6 million for the three and six months ended December 31, 2025, respectively, and $ 58.9 million and $ 115.6 million for the three and six months ended December 31, 2024, respectively. 18 Table of Contents Based on the purchased intangible assets gross carrying amount recorded as of December 31, 2025, the remaining estimated annual amortization expense is expected to be as follows: Fiscal year ending June 30: Amortization (In thousands) 2026 (remaining six months) $ 92,022 2027 129,064 2028 49,163 2029 35,606 2030 14,800 2031 and thereafter 2,316 Total $ 322,971 The expected amortization expense is an estimate. Actual amounts of amortization may differ from estimated amounts due to additional intangible asset acquisitions, changes in foreign currency exchange rates, impairment of intangible assets and other events.

Interest is payable semi-annually as follows: on January 15 and July 15 of each year for the Senior Notes due July 15, 2032, 2052, and 2062; on February 1 and August 1 of each year for the Senior Notes due February 1, 2034; on March 1 and September 1 of each year for the Senior Notes due March 1, 2050; on March 15 and September 15 of each year for the Senior Notes due March 15, 2029, and 2049; and on May 1 and November 1 of each year for the Senior Notes due November 1, 2034. The Senior Notes rank senior in right of payment to all of KLA Corporation’s future subordinated indebtedness, equally in right of payment with all of our existing and future unsecured and unsubordinated indebtedness, are effectively subordinated in right of payment to all of our 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 19 Table of Contents 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 (“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, 2025 and June 30, 2025 was $ 5.55 billion and $ 5.54 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, 2025, we were in compliance with all of our covenants under the Indenture associated with the Senior Notes. Revolving Credit Facility On July 3, 2025, we entered into a revolving credit facility (“Revolving Credit Facility”) with a maturity date of July 3, 2030 that allows us to borrow up to $ 1.50 billion, pursuant to the terms set forth in the credit agreement (“Credit Agreement”). Subject to the terms of the Credit Agreement, the Revolving Credit Facility may be increased by an amount up to $ 500.0 million in the aggregate. As of December 31, 2025, we had no outstanding borrowings under the Revolving Credit Facility. Under the Revolving Credit Facility, we may borrow, repay and reborrow funds until the maturity date, which may be extended following the exercise of no more than 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, as long as it is available. Each Term SOFR Loan will bear interest at a rate per annum equal to the applicable Adjusted Term SOFR rate, which is equal to the applicable Term SOFR rate plus a spread ranging from 62.5 bps to 100.0 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, 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 4.0 bps to 10.0 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 2024 resulted in reductions to the fees associated with our Revolving Credit Facility. As of December 31, 2025, the applicable commitment fee on the daily undrawn balance of the Revolving Credit Facility was 5.5 bps. Under the Revolving Credit Facility, the maximum net leverage ratio on a quarterly basis is 3.25 to 1.00, covering the trailing four consecutive fiscal quarters for each fiscal quarter, which may be increased to 3.75 to 1.00 for a period of time in connection with a material acquisition or a series of material acquisitions. As of December 31, 2025, our maximum allowed net leverage ratio was 3.25 to 1.00. We were in compliance with all covenants under the Credit Agreement as of December 31, 2025. NOTE 8 – 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 27 years, including periods covered by options to extend the lease when it is reasonably certain that the option will be exercised. 20 Table of Contents Lease expense was $ 14.3 million and $ 27.9 million for the three and six months ended December 31, 2025, respectively, and $ 11.9 million and $ 25.0 million for the three and six months ended December 31, 2024, 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, 2025 and 2024. As of December 31, 2025 and June 30, 2025, the weighted-average remaining lease term was 5.8 and 6.2 years, respectively, and the weighted-average discount rate for operating leases was 3.83 % and 4.06 % as of December 31, 2025 and June 30, 2025, respectively. Supplemental cash flow information related to leases was as follows: Six Months Ended December 31, In thousands 2025 2024 Operating cash outflows from operating leases $ 27,322 $ 21,258 Right of use assets obtained in exchange for new operating lease liabilities $ 40,673 $ 22,051 Maturities of lease liabilities as of December 31, 2025 were as follows: Fiscal Year Ending June 30: (In thousands) 2026 (remaining six months) $ 30,311 2027 57,569 2028 38,354 2029 32,022 2030 29,555 2031 and thereafter 63,601 Total lease payments 251,412 Less imputed interest ( 28,062 ) Total $ 223,350 As of December 31, 2025, we did not have material leases that had not yet commenced. NOTE 9 – EQUITY AND LONG-TERM INCENTIVE COMPENSATION PLANS As of December 31, 2025, 9.3 million shares remained available for issuance under the KLA Corporation 2023 Incentive Award Plan (“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, 2025.

(4) 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, 2025. The RSUs granted by us generally vest as follows, in each case subject to the recipient remaining employed by us as of the applicable vesting date: (i) with respect to awards with only service-based vesting criteria, over periods ranging from two to four years ; and (ii) with respect to awards with both performance-based and service-based vesting criteria, over periods ranging from three to four years . The RSUs granted to the independent members of the Board of Directors vest annually. As of December 31, 2025, the unrecognized SBC expense balance related to RSUs was $ 493.9 million, excluding the impact of estimated forfeitures, and will be recognized over an estimated weighted-average amortization period of 1.3 years. The intrinsic value of outstanding RSUs as of December 31, 2025 was $ 1.43 billion. 22 Table of Contents NOTE 10 – 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 $ 5.00 billion in the fourth quarter of fiscal 2025. 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, 2025, an aggregate of $ 3.94 billion 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) 2025 2024 2025 2024 Number of shares of common stock repurchased 460 979 1,083 1,719 Total cost of repurchases $ 537,553 $ 655,973 $ 1,101,953 $ 1,226,909 NOTE 11 – 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, 2025 2024 2025 2024 Numerator: Net income $ 1,145,682 $ 824,527 $ 2,266,722 $ 1,770,378 Denominator: Weighted-average shares - basic, excluding unvested RSUs 131,278 133,327 131,517 133,730 Effect of dilutive RSUs and options 731 599 688 685 Weighted-average shares - diluted 132,009 133,926 132,205 134,415 Basic net income per share $ 8.73 $ 6.18 $ 17.24 $ 13.24 Diluted net income per share $ 8.68 $ 6.16 $ 17.15 $ 13.17 Anti-dilutive securities excluded from the computation of diluted net income per share 4 145 3 36 23 Table of Contents NOTE 12 – INCOME TAXES The following table provides details of income taxes: Three Months Ended December 31, Six Months Ended December 31, (Dollar amounts in thousands) 2025 2024 2025 2024 Income before income taxes $ 1,330,303 $ 972,529 $ 2,639,779 $ 2,051,216 Provision for income taxes $ 184,621 $ 148,002 $ 373,057 $ 280,838 Effective tax rate 13.9 % 15.2 % 14.1 % 13.7 % Our effective tax rate was lower than the U.S. federal statutory rate during the three and six months ended December 31, 2025 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, 2022 and are under U.S. federal income tax examination for the fiscal year ended June 30, 2018. We have completed the federal income tax examination for the fiscal years ended 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, 2021. 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. We are under audit in Israel for calendar year ended December 31, 2019 to the fiscal year ended June 30, 2022 and received a tax assessment from the Israel Tax Authority. 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 January 2026, the Organization for Economic Co-operation and Development’s (“OECD”) introduced two new Pillar Two safe harbors which are expected to be available for fiscal years beginning on or after January 1, 2026: (1) the Side-by-Side Safe Harbor (“SBSSH”) for multinational entities headquartered in the jurisdictions with both eligible domestic and worldwide tax systems, and (2) the Ultimate Parent Entity (“UPE”) Safe Harbor for multinational entities with a UPE located in a jurisdiction that has only an eligible domestic tax system. The U.S. is an eligible jurisdiction for the SBSSH. We are not expecting a material tax impact to our Condensed Consolidated Financial Statements when countries begin to enact legislation to adopt the SBSSH provisions. In December 2025, Israel adopted the Pillar Two Global Anti-Base Erosion (“GLoBE”) rules under the Multinational Enterprise (“Minimum Tax”) Act, which includes a domestic minimum tax of 15% that will be effective for us beginning in the fiscal year ending June 30, 2027. The Pillar Two GloBE rules are deemed an alternative minimum tax so we did not recognize any deferred taxes for the estimated effects of the future minimum tax under current GAAP. We are not expecting a material tax impact to our Condensed Consolidated Financial Statements. On July 4, 2025, President Trump signed into law the One Big Beautiful Bill Act (“OBBBA”), also known as the Tax Relief for American Families and Workers Act of 2025. The OBBBA provides for several permanent changes to the U.S. tax code among other items, including modifying the Global Intangible Low-Taxed Income and Foreign-Derived Intangible Income rules from the Tax Cuts and Jobs Act; restoring full expensing for domestic research expenses; and reinstating 100% bonus depreciation provisions. ASC 740, Income Taxes, requires that the tax effects of changes in tax rates and laws be recognized in the period in which the legislation is enacted. The OBBBA provisions will result in an increase to our cash flows from operating activities and an increase to our effective tax rate in our fiscal year ending June 30, 2026. The effective tax rate changes have been reflected in the consolidated financial statements for the three and six months ended December 31, 2025, and did not have a material impact to our Condensed Consolidated Financial Statements. In November 2024, Singapore adopted the Pillar Two GloBE rules under the Minimum Tax Act, which includes a domestic minimum tax of 15% that is effective for us in the current fiscal year. There was no material impact to our Condensed Consolidated Financial Statements during the three and six months ended December 31, 2025. The Pillar Two GloBE rules are deemed an alternative minimum tax so we did not recognize any deferred taxes for the estimated effects of the future minimum tax under current GAAP. California Governor Newsom approved the 2024-25 California State Budget on June 27, 2024, which includes a provision to suspend the use of all net operating losses and limits the use of R&D tax credits to $5 million for tax years 2024 24 Table of Contents through 2026. This provision is effective in our fiscal years ended June 30, 2025 through June 30, 2027. There was no material tax impact to our Condensed Consolidated Financial Statements during the three and six months ended December 31, 2025. In December 2021, the OECD’s Inclusive Framework on Base Erosion and Profit Shifting released GloBE rules under Pillar Two. For the countries that have enacted legislation to adopt the Pillar Two GloBE rules, the provisions requiring a 15% minimum effective tax rate on income earned in the respective countries and a global 15% minimum effective top-up tax are effective for us beginning in our fiscal year ended June 30, 2025. There was no material tax impact to our Condensed Consolidated Financial Statements from these Pillar Two provisions during the three and six months ended December 31, 2025. NOTE 13 – 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. NOTE 14 – 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) 2025 2024 2025 2024 Receivables sold under factoring agreements $ 70,425 $ 38,246 $ 176,792 $ 83,705 Proceeds from sales of LC $ 2,768 $ 33,359 $ 20,994 $ 35,337 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 $ 2.75 billion as of December 31, 2025, 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, 2025, we have committed $ 116.0 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 - or four-year period. In order to receive payments under a Cash LTI award, participants must remain employed by us as of the applicable award vesting date. Guarantees, Contingencies and Other. We maintain guarantee arrangements available through various financial institutions for up to $ 164.7 million, of which $ 132.2 million had been issued as of December 31, 2025, primarily to fund 25 Table of Contents guarantees to customs authorities for value-added tax and other operating requirements of our consolidated subsidiaries worldwide. In January 2025, we entered into a long-term virtual power purchase agreement to purchase a portion of the output generated from a solar energy project for a fixed price. As part of this agreement, we will also receive renewable energy credits commensurate with the power we acquire. These credits can be applied against our greenhouse gas emissions, accelerating the progress towards our goals of 100 % renewable electricity across our global operations by 2030, reduction of our Scope 1 and 2 emissions from our 2021 baseline by 50 % by 2030 and achievement of net zero Scope 1 and Scope 2 emissions by 2050. This agreement had no material impact on our results of operations, financial condition or cash flows during the quarter ended December 31, 2025. 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. NOTE 15 – 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. 26 Table of Contents 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 12 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 (collectively, “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. As of December 31, 2025, the aggregate unamortized portion of the fair value of the forward contracts for the Rate Lock Agreements was a $ 42.9 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 on a straight-line basis over the lives of the associated derivative contracts. 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.

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 integrated circuit (“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. 30 Table of Contents The CODM uses total segment revenues and segment profit (loss) to assess performance and allocate resources (including employees, financial or capital resources), primarily during the annual strategic long-term planning and budgeting process. The CODM considers changes in market conditions, technology constraints and the competitive environment when making decisions about allocating resources to segments. The CODM does not evaluate segments using discrete asset information because asset allocation is not managed at the segment level and assets are not tracked by segment in a way that it is meaningful for decision-making. Segment profit (loss) represents segment income (loss) before income taxes, and excludes interest expense, other expense (income), net, restructuring costs, effects of changes in foreign currency exchange rates, and other corporate expenses.

EXECUTIVE SUMMARY We are a leading supplier of process control and yield management solutions and services for the semiconductor and related electronics industries. Our broad portfolio of inspection and metrology products, and related service, software and other offerings, support R&D and manufacturing of integrated circuits (“IC”), wafers and reticles. Our products, services and expertise are used by our customers to measure, detect, analyze and resolve critical and nanometric level product defects, helping them to manage manufacturing process challenges and to obtain higher finish product yields at lower cost. We also offer advanced technology solutions to address various manufacturing needs of printed circuit boards (“PCB”), specialty semiconductor devices and other electronic components, including advanced packaging, light-emitting diode (“LED”), power devices, compound semiconductor, and data storage industries, as well as general materials research. In addition, our services business has grown consistently year-over-year and accounted for approximately 24% of our total revenues in the second quarter of fiscal 2026. Our services revenue, which is generated largely from recurring “subscription-like” contracts, increases the value of our contract offerings and extension of system lifetimes resulting from growth in legacy semiconductor markets. 35 Table of Contents We are organized into three reportable segments as follows: • Semiconductor Process Control: a comprehensive portfolio of inspection, metrology and data analytics products as well as related service offerings that help IC manufacturers achieve target yields throughout the semiconductor fabrication process, from R&D to final volume production. • Specialty Semiconductor Process: advanced vacuum deposition and etching process tools used by a broad range of specialty semiconductor customers. • PCB and Component Inspection: a range of inspection, testing and measurement, and direct imaging for patterning products used by manufacturers of PCBs, advanced packaging, microelectromechanical systems (“MEMS”) and other electronic components. As we close calendar year 2025, the semiconductor industry continues to experience significant market expansion and diversification. High-performance computing and data centers, fueled by widespread adoption of AI, are driving industry growth. We expect this momentum to continue into calendar year 2026. AI is a technology inflection point driving innovation and demand at the leading edge, and we believe our portfolio of products is uniquely positioned to support leading-edge demand and the ongoing AI buildout. Our semiconductor customers generally operate in one or both of the major semiconductor device manufacturing markets: memory and foundry/logic. End-market demand drivers that are expected to continue to benefit KLA in the long term include adoption of extreme ultraviolet lithography (“EUV”) in high volume manufacturing for Logic and DRAM memory (including high-bandwidth memory), which drives new process control requirements and growth in key markets for KLA. Demand for advanced semiconductor technologies, particularly evident in the 2-nanometer node, which is seeing higher levels of investment and process control intensity, continues to drive investments in AI. Increasing complexity and value of semiconductor packages, particularly for AI and high-performance computing applications, is also driving significant growth in our advanced packaging business. The digitization of all industries, including 5G markets, advances in healthcare and industrial applications, together with the increasing adoption of electric vehicles and intelligence in automobiles, are powering leading-edge design node technology investments and capacity expansions. While we continue to invest in technological innovation, factors such as delays from customers in adopting new chips and technology methods could impact process control capital intensity. Pushouts or cancellations of deliveries to our customers could cause earnings volatility, due to the timing of revenue recognition as well as increased risk of inventory-related charges. Geopolitical factors, such as government regulations and tariffs, have had an adverse impact on our results of operations. However, despite these headwinds, our gross margin and overall financial performance improved in the three months ended December 31, 2025 compared to the three months ended December 31, 2024. Looking ahead to calendar year 2026, while we expect continued revenue growth, escalating costs for DRAM chips used in the Company’s image computers is likely to negatively impact our gross margin. We are continuously assessing the aggregate potential impact of government regulations and tariffs on our financial results and operations. See Part II, Item 1A “Risk Factors” below, and also Part I, Item 1A “Risk Factors” in our Annual Report on Form 10-K for our fiscal year ended June 30, 2025 for more information regarding how such actions by the U.S. government or another country could significantly impact our ability to provide our products and services to existing and potential customers, especially in China, and adversely affect our business, financial condition and results of operations. The following table sets forth some of our key quarterly unaudited financial information: (Dollar amounts in thousands, except net income per share) Three Months Ended December 31, 2025 September 30, 2025 June 30, 2025 March 31, 2025 December 31, 2024 Total revenues $ 3,297,146 $ 3,209,696 $ 3,174,741 $ 3,063,029 $ 3,076,851 Costs of revenues $ 1,271,210 $ 1,243,070 $ 1,207,286 $ 1,175,689 $ 1,221,461 Gross margin 61.4% 61.3% 62.0% 61.6% 60.3% Net income (1)(2) $ 1,145,682 $ 1,121,040 $ 1,202,849 $ 1,088,416 $ 824,527 Diluted net income per share (3) $ 8.68 $ 8.47 $ 9.06 $ 8.16 $ 6.16 __________________ (1) For the explanation why our net income increased to $1.15 billion in the three months ended December 31, 2025 compared to the three months ended December 31, 2024, refer to the “Results of Operations” section below, as the change is a result of movements in various income statement line items. 36 Table of Contents (2) Our net income for the three months ended December 31, 2024 included pre-tax goodwill and purchased intangible assets impairment charges of $239.1 million. For additional details, refer to Note 6 “Goodwill and Purchased Intangible Assets” in the Notes to the Consolidated Financial Statements and Note 7 “Goodwill and Purchased Intangible Assets” to our Consolidated Financial Statements included in our Annual Report on Form 10-K for the fiscal year ended June 30, 2025. (3) Diluted net income per share is computed independently for each of the quarters presented based on the weighted-average fully diluted shares outstanding for each quarter. Therefore, the sum of quarterly diluted net income per share information may not equal annual (or other multiple-quarter calculations of) diluted net income per share. We continue to focus on returning cash to our investors, making $547.8 million in share repurchases and paying $249.7 million in dividends in the three months ended December 31, 2025. We increased the dividend in the fourth quarter of fiscal 2025 to $1.90 per share per quarter, which was our 16th consecutive annual dividend increase. Refer to the “Liquidity and Capital Resources” section below for more information on our strong cash flow generation and strategy of returning excess cash to our stockholders. CRITICAL ACCOUNTING ESTIMATES The preparation of our Condensed Consolidated Financial Statements in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions in applying our accounting policies that affect the reported amounts of assets, liabilities, revenues and expenses, and related disclosure of contingent assets and liabilities. We base these estimates and assumptions on historical experience and evaluate them on an ongoing basis to ensure that they remain reasonable under current conditions. Actual results could differ from those estimates. There have been no material changes in our critical accounting estimates since our Annual Report on Form 10-K for the fiscal year ended June 30, 2025. Refer to “Management’s Discussion and Analysis of Financial Condition and Results of Operations” contained in Part II, Item 7 of our Annual Report on Form 10-K for our fiscal year ended June 30, 2025 for a complete description of our critical accounting estimates. Recent Accounting Pronouncements For a description of recent accounting pronouncements, including those recently adopted and the expected dates of adoption as well as estimated effects, if any, on our Condensed Consolidated Financial Statements of those not yet adopted, see Note 1 “Basis of Presentation” to our Condensed Consolidated Financial Statements. 37 Table of Contents RESULTS OF OPERATIONS Revenues and Gross Margin Our business is affected by the concentration of our customer base and our customers’ capital equipment procurement schedules as a result of their investment plans. Our product revenues in any particular period are impacted by the amount of new orders we receive during that period and, depending upon the duration of manufacturing and installation cycles, in the preceding periods. Revenue is also impacted by average customer pricing, customer revenue deferrals associated with volume purchase agreements, the effect of fluctuations in foreign currency exchange rates, increased trade restrictions and the availability of government incentives for semiconductor capital investments. Service revenues are generated from product maintenance and support services, as well as billable time and material service calls made to our customers. The amount of our service revenues is typically a function of the number of systems installed at our customers’ sites and the utilization of those systems, but it is also impacted by other factors, such as our rate of service contract renewals, the types of systems being serviced and fluctuations in foreign currency exchange rates. A significant portion of our revenues continues to be generated in Asia, where a substantial portion of the world’s semiconductor manufacturing capacity is located, and we expect that trend to continue.
