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 ~~September~~December 3031, 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. ~~There~~Except for the below change, 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, 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.

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

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 ~~three~~six months ended ~~September~~December 3031, 2025 was mainly due to $6584.85 million of ~~revenue~~contract ~~recognized~~assets ~~for~~reclassified ~~which~~to ~~the~~accounts ~~payment~~receivable, isnet, ~~subject~~as our right to ~~conditions~~consideration ~~other~~for ~~than~~these ~~passage~~contract ofassets ~~time~~became unconditional, partially offset by $4772.27 million of ~~contract~~revenue ~~assets~~recognized ~~reclassified~~for towhich ~~accounts~~the ~~receivable,~~payment ~~net,~~is assubject ~~our right~~ to ~~consideration~~conditions ~~for~~other ~~these~~than ~~contract~~passage ~~assets~~of ~~became unconditional~~time. Contract assets are included in other current assets on our Condensed Consolidated Balance Sheets.

The change in contract liabilities during the ~~three~~six months ended ~~September~~December 3031, 2025 was mainly due ~~to the recognition of revenue of $738.7 million that was included in contract liabilities as of June 30, 2025, largely offset by~~ an increase in the value of products and services billed to customers for which control of the products and services has not transferred to the customers, 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 ~~September~~December 3031, 2025, which equals our contract liabilities, and when the Company expects to recognize the amounts as revenue:

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.

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.

(1)We have a non-qualified deferred compensation plan (known as the “Executive Deferred Savings Plan” or “EDSP”) under which certain employees and non-employee directors may defer a portion of their compensation. The expense associated with changes in the EDSP liability included in selling, general and administrative (“SG&A”) was $186.24 million and $183.03 million in the three months ended ~~September~~December 3031, 2025 and 2024, respectively, and was $24.6 million and $21.3 million during the six months ended December 31, 2025 and 2024, respectively. The amount of net gains associated with changes in the EDSP assets included in SG&A expense was $186.2 million and $173.95 million in the three months ended ~~September~~December 3031, 2025 and 2024, respectively, and was $24.4 million and $21.4 million during the six months ended December 31, 2025 and 2024, respectively.

Our investment portfolio includes both corporate and government securities that have a maximum maturity of three years. The longer the duration of these securities, the more susceptible they are to changes in market interest rates and bond yields. As yields increase, those securities with a lower yield-at-cost show a mark-to-market unrealized loss. Most of our unrealized losses are due to changes in market interest rates and bond yields. We believe that we have the ability to realize the full value of all these investments upon maturity. As of ~~September~~December 3031, 2025, we had 5043 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.

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 ~~three~~six months ended ~~September~~December 3031, 2025:

(In thousands)	Semiconductor Process Control		Specialty Semiconductor Process		Printed Circuit Board ("“PCB"”) and Component Inspection		Total

Balances as of December 31, 2025	$	759,967	$	681,272	$	349,358	$	1,790,597

As of ~~September~~December 3031, 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.

AsDuring the second quarter of ~~September~~fiscal 302026, ~~2025,~~the ~~there~~Company ~~have~~changed ~~been~~the noannual ~~significant~~goodwill ~~events~~impairment ortesting ~~circumstances~~date ~~affecting~~for all reporting units from February 28 to December 31 to better align with the ~~valuation~~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 ~~subsequent~~as those decisions are reached. This will also enable us to use the ~~annual~~most ~~assessment~~current ~~performed~~information available in the ~~third~~assessment ~~quarter~~process. ofThe change in the ~~fiscal~~measurement ~~year~~date ~~ended~~did ~~June~~not 30delay, ~~2025~~accelerate or avoid recognition of an impairment charge. ~~For~~Each ~~additional~~quarter ~~details,~~the ~~refer~~Company evaluates impairment indicators to ~~Note~~determine 7,whether ~~“Goodwill~~a ~~and~~triggering ~~Purchased~~event ~~Intangible~~has ~~Assets”~~occurred which would warrant a quantitative assessment to ~~our~~determine ~~Consolidated~~whether ~~Financial~~there ~~Statements~~has ~~included~~been inan ~~the~~impairment. ~~Company's~~We ~~Annual~~have ~~Report~~applied this change on ~~Form~~a ~~10-K~~prospective basis for the fiscal year ~~ended~~ending June 30, ~~2025~~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

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:

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 ~~September~~December 3031, 2025, there were no impairment indicators for purchased intangible assets.

16In 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.

Senior Notes and Debt Redemption

The original discounts on the senior, unsecured long-term notes listed in the table above (collectively, “Senior Notes”) are being amortized over the life of the debt. 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

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 ~~September~~December 3031, 2025 and June 30, 2025 was $5.6355 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 ~~September~~December 3031, 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 ~~September~~December 3031, 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 ~~September~~December 3031, 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 ~~September~~December 3031, 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 ~~September~~December 3031, 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.

As of ~~September~~December 3031, 2025, 9.43 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.

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 ~~September~~December 3031, 2025, an aggregate of $43.4794 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:

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:

21Our 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.

Table of Contents

Our effective tax rate was lower than the U.S. federal statutory rate during the three months ended September 30, 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.

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 September 30,
	Three Months Ended December 31,				Six Months Ended December 31,
(In thousands)	2025		2024		2025		2024

Proceeds from sales of LC	$	182,~~226~~768	$	133,~~978~~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 $2.5075 billion as of ~~September~~December 3031, 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 ~~September~~December 3031, 2025, we have committed $116.60 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 $~~129~~164.87 million, of which $94132.82 million had been issued as of ~~September~~December 3031, 2025, primarily to fund ~~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 September 30, 2025.25

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.

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.

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.

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 ~~September~~December 3031, 2025, the aggregate unamortized portion of the fair value of the forward contracts for the Rate Lock Agreements was a $4342.79 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.

NOTE 16 – SEGMENT REPORTING AND GEOGRAPHIC INFORMATION

ASC 280, Segment Reporting, establishes standards for reporting information about operating segments. Operating segments are defined as components of an enterprise about which separate financial information is evaluated regularly by the chief operating decision maker (“CODM”) in deciding how to allocate resources and in assessing performance. Our CODM is our Chief Executive Officer.

Our operating segments are aggregated into reportable segments based on several factors including, but not limited to, customer base, homogeneity of products, technology, delivery channels and similar economic characteristics. We have three reportable segments: Semiconductor Process Control; Specialty Semiconductor Process; and PCB and Component Inspection.

Semiconductor Process Control

The Semiconductor Process Control segment offers a comprehensive portfolio of inspection, metrology and data analytics products, and related services, which helps 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.

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.

The following is a summary of results for each of our three reportable segments for the indicated periods:

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 2324% of our total revenues in the ~~first~~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.

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.

~~The~~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 ~~believe~~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 ~~September 30~~December 31, 2025 compared to the three months ended ~~September 30~~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.

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.

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.

Excluding the goodwill impairment charge during the six months ended December 31, 2024, the effective tax rate during the six months ended December 31, 2025 was higher compared to the six months ended December 31, 2024 primarily due to a decrease in the proportion of earnings generated in jurisdictions with tax rates lower than the U.S. statutory rates and a decrease in the proportion of U.S. earnings eligible for the Foreign Derived Intangible Income deduction, partially offset by a decrease in our Global Intangible Low-Taxed Income.

Our future effective income tax rate depends on various factors, such as tax legislation, the geographic composition of our pre-tax income, the amount of our pre-tax income as business activities fluctuate, non-deductible expenses incurred in connection with acquisitions, R&D credits as a percentage of aggregate pre-tax income, non-taxable or non-deductible increases or decreases in the assets held within our Executive Deferred Savings Plan, the tax effects of employee stock activity and the effectiveness of our tax planning strategies. We also continue to monitor the adoption of Pillar Two relating to the global minimum tax in each of our tax jurisdictions to evaluate its impact on our effective income tax rate. For some of the jurisdictions that have adopted Pillar Two in their tax legislation, it was effective for us beginning in our fiscal year ended June 30, 2025.

Cash, Cash Equivalents and Marketable Securities

As of ~~September~~December 3031, 2025, our cash, cash equivalents and marketable securities totaled $45.6821 billion, compared to the $4.49 billion balance as of June 30, 2025. Refer to below discussions of sources and uses of cash during the ~~three~~six months ended ~~September~~December 3031, 2025. As of ~~September~~December 3031, 2025, $1.125 ~~million~~billion of our $45.6821 billion of cash, cash equivalents and marketable securities were held by our foreign subsidiaries and branch offices. We have recorded appropriate provisions for income or withholding taxes that may result from future repatriations of this balance.

Cash Flows Provided by Operating Activities

We typically finance our liquidity requirements through cash generated from our operations. Net cash provided by operating activities during the ~~three~~six months ended ~~September~~December 3031, 2025 was $12.1653 billion compared to $~~995~~1.284 ~~million~~billion during the ~~three~~six months ended ~~September~~December 3031, 2024. This increase was primarily due to an increase in customer and other collections of approximately $~~515~~1.2 ~~million~~billion primarily driven by higher shipments and a decrease in income tax payments of $55 million; partially offset by increases in accounts payable payments of approximately $~~230~~460 million and employee-related payments of approximately $55100 million.

Cash Flows Used in Investing Activities

Net cash used in investing activities during the ~~three~~six months ended ~~September~~December 3031, 2025 was $~~410~~522.07 million compared to $~~171~~442.07 million of net cash provided during the ~~three~~six months ended ~~September~~December 3031, 2024. This increase in cash used was primarily due to increases in net purchases of available-for-sale securities of $~~206~~931.48 million, and capital expenditures of $3548.57 million, partially offset by a $16.8 million increase in proceeds from capital-related government assistance.

Cash Flows Used in Financing Activities

Net cash used in financing activities during the ~~three~~six months ended ~~September~~December 3031, 2025 was $~~881~~1.863 ~~million~~billion compared to $~~837~~2.742 ~~million~~billion during the ~~three~~six months ended ~~September~~December 3031, 2024. This ~~increase~~decrease in cash used was primarily due to a $750.0 million debt repayment during the six months ended December 31, 2024 and a decrease in common stock repurchases of $124.7 million, partially offset by increases in payment of dividends and dividend equivalents of $5578.98 million and tax withholding payments related to vested and released restricted stock units (“RSU”) of $811.90 million~~, partially offset by a decrease in common stock repurchases of $22~~.~~3 million.~~

Stock Repurchases

The shares of common stock repurchased under our stock repurchase program have reduced our basic and diluted weighted-average shares outstanding for the ~~three~~six months ended ~~September~~December 3031, 2025 and 2024. The total amount of stock repurchases during the ~~three~~six months ended ~~September~~December 3031, 2025 and 2024 were $~~545.~~1.09 ~~million~~billion and $~~567~~1.422 ~~million~~billion, respectively. The stock repurchase program is intended, in part, to mitigate the potential dilutive impact related to our equity incentive plans and shares issued in connection with our Employee Stock Purchase Program as well as to return excess cash to our stockholders. As of ~~September 30~~December 31, 2025, an aggregate of $43.4794 billion was available for repurchase under our stock repurchase program, which reflects an increase in the authorized repurchase amount of $5.00 billion in the fourth quarter of fiscal 2025.

Cash Dividends

During the three months ended ~~September~~December 3031, 2025, our Board of Directors declared a regular quarterly cash dividend of $1.90 per share on our outstanding common stock, which was paid on ~~September~~December 32, 2025 to our stockholders of record as of the close of business on ~~August~~November 1817, 2025. During the same period in fiscal year ended June 30, 2025, our Board of Directors declared and paid a regular quarterly cash dividend of $1.4570 per share on our outstanding common stock. The total amount of regular quarterly cash dividends and dividend equivalents paid during the three months ended ~~September~~December 3031, 2025 and 2024 was $~~254~~249.07 million and $~~198~~226.18 million, respectively. The total amount of regular quarterly cash dividends and dividend equivalents paid during the six months ended December 31, 2025 and 2024 was $503.7 million and $424.9 million, respectively. The amount of accrued dividend equivalents payable for regular quarterly cash dividends on unvested RSUs with dividend equivalent rights as of ~~September~~December 3031, 2025 and June 30, 2025 was $1113.87 million and $13.3 million, respectively. These amounts will be paid upon vesting of the underlying unvested RSUs as described in Note 9 “Equity and Long-term Incentive Compensation Plans” to our Condensed Consolidated Financial Statements.

As of ~~September~~December 3031, 2025, we had an aggregate principal amount of senior, unsecured notes totaling $5.95 billion (collectively, “Senior Notes”) with due dates ranging from fiscal 2029 through fiscal 2063. For additional information on these Senior Notes, see Note 7 “Debt” to our Condensed Consolidated Financial Statements. As of ~~September~~December 3031, 2025, we were in compliance with all of our covenants under the Indenture associated with the Senior Notes.

~~Revolving Credit Facility~~44

Table of Contents

~~Credit Agreement, the~~ Revolving Credit Facility may be increased by an amount up to $500.0 million in the aggregate. As of September 30, 2025, we had no outstanding borrowings under the Revolving Credit Facility. We were in compliance with all covenants under the Credit Agreement as of September 30, 2025 (the net leverage ratio was 0.57 to 1.00, compared to a maximum net leverage ratio of 3.25 to 1.00 on a quarterly basis covering the trailing four consecutive fiscal quarters for each fiscal quarter). Considering our current liquidity position, short-term financial forecasts and ability to prepay the Revolving Credit Facility, if necessary, we expect to continue to be in compliance with our financial covenants at the end of our fiscal year ending June 30, 2026.

We have in place a Credit Agreement (“Credit Agreement”) for an unsecured Revolving Credit Facility (“Revolving Credit Facility”) with a maturity date of July 3, 2030 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 $500.0 million in the aggregate. As of December 31, 2025, we had no outstanding borrowings under the Revolving Credit Facility. We were in compliance with all covenants under the Credit Agreement as of December 31, 2025 (the net leverage ratio was 0.56 to 1.00, compared to a maximum net leverage ratio of 3.25 to 1.00 on a quarterly basis covering the trailing four consecutive fiscal quarters for each fiscal quarter). Considering our current liquidity position, short-term financial forecasts and ability to prepay the Revolving Credit Facility, if necessary, we expect to continue to be in compliance with our financial covenants at the end of our fiscal year ending June 30, 2026.

For additional information on the Revolving Credit Facility, see Note 7 “Debt” to our Condensed Consolidated Financial Statements.

Material Cash Requirements

For details regarding our debt and other material cash commitments, refer to Note 7 “Debt” and Note 14 “Commitments and Contingencies,” respectively, to our Condensed Consolidated Financial Statements. For additional details regarding our material cash requirements, refer to “Material Cash Requirements” in the “Liquidity and Capital Resources” section of Part II, Item 7 “Management'’s Discussion and Analysis of Financial Condition and Results of Operations” in our Annual Report Form on 10-K for the fiscal year ended June 30, 2025.

Off-Balance Sheet Arrangements

As of ~~September~~December 3031, 2025, we did not have any off-balance sheet arrangements that have or are reasonably likely to have a current or future effect on our financial position, changes in financial condition, revenues and expenses, results of operations, liquidity, capital expenditures or capital resources that are material to investors. Refer to Note 14 “Commitments and Contingencies” to our Condensed Consolidated Financial Statements for information related to indemnification obligations.

Working Capital

Working capital was $67.8528 billion as of ~~September~~December 3031, 2025, which represents an increase of $~~238~~668.23 million compared to our working capital of $6.61 billion as of June 30, 2025. As of ~~September~~December 3031, 2025, our principal sources of liquidity consisted of $45.6821 billion of cash, cash equivalents and marketable securities, as well as $1.50 billion availability under our Revolving Credit Facility. Our liquidity may be affected by many factors, some of which are based on the normal ongoing operations of the business, spending for business acquisitions, and other factors such as uncertainty in the global and regional economies and the semiconductor, semiconductor-related and electronic device industries. Although cash requirements will fluctuate based on the timing and extent of these factors, we believe that cash generated from operations, together with the liquidity provided by existing cash and cash equivalents balances, marketable securities and our Revolving Credit Facility, will be sufficient to satisfy our liquidity requirements associated with working capital needs, capital expenditures, cash dividends, stock repurchases and other contractual obligations for at least the next 12 months.

Credit Ratings

Our credit ratings as of ~~September~~December 3031, 2025 are summarized below:


Rating Agency			Rating
Fitch Inc.			A
Moody’s Investors Service			A2
S&P Global Ratings			A-

Factors that can affect our credit ratings include changes in our operating performance, the economic environment, conditions in the semiconductor and semiconductor capital equipment industries, our financial position, material acquisitions and changes in our business strategy.

ITEM 4 CONTROLS AND PROCEDURES

Evaluation of Disclosure Controls and Procedures and Related CEO and CFO Certifications

Evaluation of Disclosure Controls and Procedures

We conducted an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures (as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act (“Disclosure Controls”) as of the end of the period covered by this Quarterly Report on Form 10-Q (this “Report”) required by Exchange Act Rules 13a-15(b) or 15d-15(b). The Disclosure Controls evaluation was conducted under the supervision and with the participation of our management, including our Chief Executive Officer (“CEO”) and Chief Financial Officer (“CFO”). Based on this evaluation, the CEO and CFO have concluded that, as of the end of the period covered by this Report, our Disclosure Controls were effective at a reasonable assurance level.

Attached as exhibits to this Report are certifications of the CEO and CFO that are required in accordance with Rule 13a-14 of the Exchange Act. This Controls and Procedures section includes the information concerning the controls evaluation referred to in the certifications, and it should be read in conjunction with the certifications for a more complete understanding of the topics presented.

Definition of Disclosure Controls

Disclosure Controls are controls and procedures designed to reasonably ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act, such as this Report, is recorded, processed, summarized and reported within the time periods specified in the U.S. Securities and Exchange Commission’s rules and forms. Disclosure Controls are also designed to provide reasonable assurance that such information is accumulated and communicated to our management, including our CEO and CFO, as appropriate to allow timely decisions regarding required disclosure. Our Disclosure Controls include components of our internal control over financial reporting, which consists of control processes designed to provide reasonable assurance regarding the reliability of our financial reporting and the preparation of financial statements in accordance with generally accepted accounting principles in the United States of America. To the extent that components of our internal control over financial reporting are included within our Disclosure Controls, they are included in the scope of our annual controls evaluation.

Limitations on the Effectiveness of Disclosure Controls

Our management, including our CEO and CFO, does not expect that our Disclosure Controls or internal control over financial reporting will prevent all error and fraud. A control system, no matter how well designed and operated, can provide only reasonable, not absolute, assurance that the control system’s objectives will be met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits of controls must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control issues and instances of fraud, if any, within the Company have been detected. These inherent limitations include the realities that judgments in decision making can be faulty and that breakdowns can occur because of simple errors or mistakes. Controls can also be circumvented by the individual acts of some persons, by collusion of two or more people, or by management override of the controls. The design of any system of controls is based in part on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving our stated goals under all potential future conditions. Over time, controls may become inadequate because of changes in conditions or deterioration in the degree of compliance with policies or procedures. Because of the inherent limitations in a cost-effective control system, misstatements due to error or fraud may occur and not be detected.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting identified in connection with the evaluation required by Rule 13a-15(d) and 15d-15(d) of the Exchange Act that occurred during the most recent fiscal quarter covered by this Report that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.

PART II. OTHER INFORMATION

ITEM 1. LEGAL PROCEEDINGS

The information set forth above under Note 13 “Litigation and Other Legal Matters” to our Condensed Consolidated Financial Statements in Item 1 of Part 1 is incorporated herein by reference.

ITEM 1A. RISK FACTORS

Other than the risk factors listed below, there have been no material changes in our risk factors since our Annual Report on Form 10-K for the fiscal year ended June 30, 2025. Refer to “Risk Factors” contained in Part I Item 1A of our Annual Report on Form 10-K for our fiscal year ended June 30, 2025 for a complete description of our risk factors. Any of these risks, as well as risks unknown to us or that we believe are currently immaterial, could have a material adverse impact on our business, financial condition or results of operations.

Over the past several years, there have been a variety of rules and regulations issued by Commerce that have had an impact on our ability to sell certain products and provide certain services to certain customers in China. These rules and regulations may significantly harm our business, results of operations, financial condition and cash flows in future periods, unless we are able to obtain required licenses.

We maintain significant operations outside the United States, and existing and evolving trade restrictions imposed by the U.S. and other governments could significantly disrupt our global operations. The U.S. government has tightened export controls for commodities, software, and technology (collectively, “items”) destined to China over the past several years. These controls have included, for example, restrictions on exporting certain items to military end users and for military end uses, the addition of numerous entities to the U.S. Entity List (a list of parties that are generally ineligible to receive U.S.-regulated items without prior licensing from Commerce), and the creation of new licensing requirements that apply to the export, re-export, and transfer of certain foreign-made items that are the direct product of U.S. origin technology or produced by a plant or major component of a plant that itself is the direct product of U.S. origin technology and which are destined to Huawei or its affiliates and other specified companies on the U.S. Entity List, and other facilities in China where the production of advanced node IC occurs.

In October 2022, Commerce published the 2022 BIS Rules (the “2022 BIS Rules”) that introduced restrictions related to semiconductor, semiconductor manufacturing, supercomputer, and advanced computing items and end uses. These rules impose restrictions on our ability to sell, ship and support certain equipment and otherwise conduct business with certain counterparties, primarily including China-based companies involved in advanced semiconductor manufacturing. Further, the 2022 BIS Rules impose restrictions on the activities of U.S. persons with respect to certain items that are not subject to the Export Administration Regulations (“EAR”), which departs from Commerce’s typical practice of controlling items that are subject to the EAR, and could further restrict our ability to conduct business in China. In October 2023, Commerce issued the 2023 BIS Rules (the “2023 BIS Rules”) 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 certain D1, D4 and/or D5 countries in Supplement No. 1 of Part 740 of the U.S. EAR, including China. The 2023 BIS Rules adjust the parameters included in the 2022 BIS Rules that determine whether an advanced computing chip is restricted and impose new measures to address risks of circumvention of the controls established by the 2022 BIS Rules.

In December 2024 and January 2025, Commerce again issued incremental 2024 BIS Rules and 2025 BIS Rules, adding even more companies to the U.S. Entity List and revising the definition of advanced DRAM, further restricting our ability to provide certain items and services to facilities in China producing advanced DRAM ICs.

In September 2025, Commerce released an interim final rule that further expands export control restrictions and licensing requirements for foreign entities 50% or more directly or indirectly owned by one or more listed parties on the U.S. Entity List, Military End-User List, and certain entities on the Specially Designated Nationals and Block Persons ~~(“SDN)”~~ List, which Commerce has labeled the “Affiliates Rule”.” The new rule increases compliance requirements with the EAR by imposing on exporters, re-exporters, and transferors of items subject to the EAR a responsibility to know the ownership of the parties to a transaction. ~~The~~In ~~Affiliates~~November ~~Rule~~2025, isthe ~~effective~~BIS ~~immediately,~~suspended ~~though~~the itAffiliates isRule ~~not~~for ~~yet~~one ~~considered~~year ~~final~~until November 2026.

Commerce may continue to add China-based entities to the U.S. Entity List and impose other end use or end user export restrictions, which could disrupt or prevent our product shipment, and further disrupt our revenue recognition, business operations and our ability to support our customers in China.

These rules and regulations may significantly harm our business unless we are able to obtain required licenses. We will continue to apply for export licenses, when required, in an effort to avoid disruption to our and our customers’ operations, but

4247

Table of Contents

there can be no assurance that export licenses applied for by either us or our customers, now or in the future, will be granted. To the extent Commerce does issue licenses to us or to our customers, such licenses may have a short duration or require us to satisfy various conditions. If pending and future export license applications are not granted, or additional restrictions are imposed, or if regulators adopt new interpretations of existing regulations, the potential impact on us could be material by disrupting our supply chain and product shipment, impairing our ability to complete product development in a timely manner, or our ability to support existing customers of covered products or supply customers of covered products outside the impacted regions, and requiring us to transition certain operations out of one or more of the identified countries. Failure to obtain export licenses has harmed and could continue to harm our backlog, requiring us to return substantial deposits received from customers in China for purchase orders, and/or further limiting our ability to meet our contractual obligations and sell our products or provide services to our customers in China. In addition, the U.S. export restrictions on semiconductors and semiconductor technology to China and Chinese customers may reduce the need for our products and make it easier for our China-based competitors to develop and sell their own products and take market share from us.

We may lose revenue in future periods related to anticipated sales to customers in China unless we are able to replace their orders with other customer orders for which either an export license has been obtained or is not required. Our revenue from sales of products and provision of services to customers in China was 33%, 43% and 27% for fiscal years 2025, 2024 and 2023, respectively, and future revenue from China as a percentage of our overall revenue may decline as a result of the current and future Commerce rules and regulations.

Additionally, the Chinese government has adopted, and may further adopt, new regulations, in response to U.S. government actions, which could adversely affect our ability to do business in China.

We have faced delays and could face additional delays or denials in the export of our tools by regulatory agencies for national security or other regulatory concerns in the countries in which we do business, which could negatively affect our results of operations and timing of revenue recognition. We have controls and procedures designed to maintain compliance with U.S. and other applicable export control laws and regulations; however, we cannot guarantee that such controls and procedures will be successful in preventing violations or allegations of violations, of increasingly complex and often conflicting regulations worldwide. The complexity and evolving nature of the rules and regulations, and the fact that Commerce or other relevant regulators might adopt interpretations of regulations that differ from those of the Company, increase our risk of non-compliance.

Any violations by us of applicable export laws and regulations could result in significant civil and criminal penalties, including fines and criminal proceedings against the Company or responsible employees, a denial of export privileges, suspension or debarment. Our employees, customers, suppliers or other third parties with whom we work may also engage in conduct for which the Company might be held responsible. We could face significant compliance, litigation or settlement costs and diversion of management’s attention from our business as a result. Further, the Company may be subject to negative publicity or reputational harm, resulting in reduced demand for our products, employee attrition and other negative impact on our business, results of operations, financial condition and cash flows.

A change in our effective tax rate can have a significant adverse impact on our business.

We earn profits in, and are therefore potentially subject to taxes in, the U.S. and numerous foreign jurisdictions, including Singapore and Israel, the countries in which we earn the majority of our non-U.S. profits. Due to economic, political or other conditions, tax rates in those jurisdictions may be subject to significant change. A number of factors may adversely impact our future effective tax rates, such as the jurisdictions in which our profits are determined to be earned and taxed; changes in the tax rates imposed by those jurisdictions; expiration of tax holidays in certain jurisdictions that are not renewed; the resolution of issues arising from tax audits with various tax authorities; changes in the valuation of our deferred tax assets and liabilities; adjustments to estimated taxes upon finalization of various tax returns; increases in expenses not deductible for tax purposes, including write-offs of acquired in-process research and development and impairment of goodwill in connection with acquisitions; changes in available tax credits; changes in stock-based compensation expense; changes in tax laws or the interpretation of such tax laws; changes in generally accepted accounting principles; and the repatriation of earnings from outside the U.S. for which we have not previously provided for U.S. taxes. A change in our effective tax rate can materially and adversely impact our results from operations.

In addition, changes to U.S. tax laws will significantly impact how U.S. multinational corporations are taxed on U.S. and foreign earnings. On July 4, 2025, the enactment of the One Big Beautiful Bill Act (“OBBBA”) provides for several permanent changes to the ~~United~~U. ~~States~~S. tax code including, among other items, modifying the Global Intangible Low-Taxed Income (“GILTI”) and Foreign-Derived Intangible Income (“FDII”) rules that were included in the Tax Cuts and Jobs Act, which was enacted into law on December 22, 2017.

The OBBBA renames GILTI to Net Controlled Foreign Corporation (“CFC”) Tested Income (“NCTI”) and modifies the percentage of foreign earnings under the GILTI regime that is taxable in the U.S. from 50% to 40% for tax years beginning after December 31, 2025. It also renames FDII to Foreign-Derived Deduction Eligible Income (“FDDEI”) and modifies the percentage of U.S. earnings under the FDII regime that is not subject to tax in the U.S. from 37.5% to 33.34% for tax years 48

Table of Contents

On August 16, 2022, the enactment of the Inflation Reduction Act (“IRA”) introduced a corporate alternative minimum tax (“CAMT”) that was effective for us beginning in the quarter ended September 30, 2023. The CAMT applies a 15% minimum income tax rate on certain large corporations. Although we were not subject to the CAMT in our fiscal year ended June 30, 2025, the enactment of the OBBBA and interpretations of such law may result in our subjection to CAMT liability in future periods, which can have a material and adverse impact to our future effective tax rate.

Numerous countries are evaluating their existing tax laws due, in part, to recommendations made by the Organization for Economic Co-operation and Development’s (“OECD”) Base Erosion and Profit Shifting (“BEPS”) project. The OECD continues to advance its work under the BEPS 2.0 initiative to develop the framework for Pillar Two, which aims to implement a global minimum tax of 15%. Many countries have enacted or drafted legislation using the Pillar Two framework to propose domestic tax laws requiring a minimum tax rate of 15% (“top-up tax”) on income earned in the respective countries. ~~One country that has adopted Pillar Two legislation is Singapore, where KLA earns significant profits and currently benefits from tax incentives granted by the Singapore Economic Development Board.~~ The tax liability from top-up tax may have a material and adverse impact to our effective tax rate ~~beginning in the quarter ending September 30, 2026~~.

Our business would be harmed if we do not receive parts sufficient in number and performance to meet our production requirements and product specifications in a timely and cost-effective manner.

We use a wide range of materials in the production of our products, including custom electronic and mechanical components, and we use numerous suppliers to supply these materials. Generally, we do not have guaranteed supply arrangements with our suppliers. Because of the variability and uniqueness of customers’ orders, we do not maintain an extensive inventory of materials for manufacturing. Through our business interruption planning, we seek to minimize the risk of production and service interruptions and/or shortages of key parts by, among other things, monitoring the financial stability of key suppliers, identifying (but not necessarily qualifying) possible alternative suppliers and maintaining appropriate inventories of key parts. Although we make reasonable efforts to ensure that parts are available from multiple suppliers, certain key parts are available only from a single supplier or a limited group of suppliers. Also, key parts we obtain from some of our suppliers incorporate the suppliers’ proprietary IP; in those cases, we are increasingly reliant on third parties for high-performance, high-technology components, which reduces the amount of control we have over the availability and protection of the technology and IP that is used in our products. In addition, if certain of our key suppliers experience liquidity issues and are forced to discontinue operations, which is a heightened risk, especially during economic downturns, it could affect their ability to deliver parts and could result in delays for our products. Similarly, especially with respect to suppliers of high-technology components, our suppliers themselves have increasingly complex supply chains, and delays or disruptions at any stage of their supply chains may prevent us from obtaining parts in a timely manner and result in delays for our products, or our suppliers might pass on the cost of inflation to us while we are unable to adjust pricing with our own customers. In April 2025, the Chinese government imposed export controls on seven of the seventeen elements classified as rare earth elements. In October 2025, the Chinese government imposed additional restrictions and licensing requirements on certain rare earth elements, some of which became effective immediately on the announcement date and other portions of the regulations become effective in November 2025. The Chinese government imposed export controls on an additional five rare earth elements and certain license requirements for items made outside of China that incorporate controlled rare earth elements. It is estimated that China controls about 70% of the worldwide mining of rare earth elements, 90% of the separation and processing of those elements and 93% of the magnets manufactured from those elements. Rare earth elements are critical to certain components contained in our products. If our suppliers are unable to provide the components necessary to make our products because of restrictions placed on their access to rare earth elements or products derived from rare earth elements, our business, financial condition and results of operations could be materially harmed. Our operating results and business may be adversely impacted if we are unable to obtain parts to meet our production requirements and product specifications, or if we are able to do so only on unfavorable terms. Furthermore, a supplier may discontinue production of a particular part for any number of reasons, including the supplier’s financial condition or business operational decisions, which would require us to purchase, in a single transaction, a large number of such discontinued parts in order to ensure that a continuous supply of such parts remains available to our customers. Such “end-of-life” parts purchases could result in significant expenditures by us in a particular period, and, ultimately, any unused parts may result in a significant inventory write-off, either of which could have an adverse impact on our financial condition and results of operations for the applicable periods.

Recently, a few large suppliers have discontinued manufacturing certain DRAM chips that are incorporated in a number of our products, and the resulting shortage has caused a dramatic increase in the prices to

Table of Contents

acquire these chips. Our efforts to procure these chips also contributed to an increase in purchase commitments in the second quarter of fiscal 2026. We estimate that the additional costs to procure these DRAM chips will have an adverse impact on our gross margin in calendar 2026. If we are unable to acquire adequate supply of such chips or acquire them in a timely or cost-controlled manner, our results of operations could be harmed.
