Item 8.01 Other Events

On April 30, 2025, the Board of Directors (the “Board”) of the Company established a quarterly dividend level of $1.90 per share on the outstanding shares of the Company’s common stock, which represents the anticipated level at which dividends will be declared by the Board until the Board determines otherwise, beginning with the dividend expected to be declared in May 2025. The declaration and payment of future dividends is subject to the Board’s discretion and will depend on financial and legal requirements and other considerations.

Also, on April 30, 2025, the Board approved a new share repurchase program that authorizes the repurchase of up to $5 billion of shares of the Company’s common stock. This share repurchase program is in addition to the $2 billion share repurchase program announced in September 2023, which as of March 31, 2025, had approximately $457 million of repurchase authority remaining.

Under the repurchase programs, repurchases can be made using a variety of methods, which may include open market purchases, privately negotiated transactions, accelerated share repurchase programs, or otherwise, all in accordance with the requirements of the Securities and Exchange Commission and other applicable legal requirements. The specific timing, price and size of purchases will depend on prevailing stock prices, general economic and market conditions, and other considerations. The repurchase programs do not obligate the Company to acquire any particular amount of its common stock, and the repurchase programs may be suspended or discontinued at any time at the Company’s discretion.

The non-GAAP and supplemental information provided in this press release is a supplement to, and not a substitute for, KLA’s financial results presented in accordance with United States GAAP.

To supplement our Condensed Consolidated Financial Statements presented in accordance with GAAP, we provide certain non-GAAP financial information, which is adjusted from results based on GAAP to exclude certain gains, costs and expenses, as well as other supplemental information. The non-GAAP and supplemental information is provided to enhance the user’s overall understanding of our operating performance and our prospects in the future. Specifically, we believe that the non-GAAP information, including non-GAAP net income, non-GAAP net income per diluted share, non-GAAP gross margin and free cash flow, provides useful measures to both management and investors regarding financial and business trends relating to our financial performance by excluding certain costs and expenses that we believe are not indicative of our core operating results to help investors compare our operating performances with our results in prior periods as well as with the performance of other companies. The non-GAAP information is among the budgeting and planning tools that management uses for future forecasting. However, because there are no standardized or generally accepted definitions for most non-GAAP financial metrics, definitions of non-GAAP financial metrics are inherently subject to significant discretion (for example, determining which costs and expenses to exclude when calculating such a metric). As a result, non-GAAP financial metrics may be defined very differently from company to company, or even from period to period within the same company, which can potentially limit the usefulness of such information to an investor. The presentation of non-GAAP and supplemental information is not meant to be considered in isolation or as a substitute for results prepared and presented in accordance with United States GAAP. The following are descriptions of the adjustments made to reconcile GAAP net income to non-GAAP net income:

a.Acquisition-related charges primarily include amortization of intangible assets and write-offs due to abandonment of in-process research and development projects. Although we exclude the effect of amortization of all acquired intangible assets from these non-GAAP financial measures, management believes that it is important for investors to understand that such intangible assets were recorded as part of purchase price accounting arising from acquisitions, and such amortization of intangible assets related to past acquisitions will recur in future periods until such intangible assets have been fully amortized. Investors should note that the use of these intangible assets contributed to our revenues earned during the periods presented and are expected to contribute to our future period revenues as well.

b.Restructuring, severance and other charges primarily include costs associated with employee severance.

c.Impairment of goodwill and purchased intangible assets in the nine months ended March 31, 2025, the three and nine months ended March 31, 2024, and the three months ended December 31, 2024 include non-cash expense recognized as a result of the company's testing for goodwill impairment and long-lived assets impairment. The impairment charge in fiscal 2024 resulted from the downward revision of financial outlook for our PCB and Display reporting units, and the subsequent decision to exit the Company's Display business that was based on many factors, including the cancellation of a significant new technology project by a major customer in the third quarter of fiscal 2024. The impairment charge in fiscal 2025 resulted from the continued deterioration of the long-term forecast for our PCB business. Management believes that it is appropriate to exclude these impairment charges as they are not indicative of ongoing operating results and therefore limit

comparability. Management also believes excluding this item helps investors compare our operating performance with our results in prior periods as well as with the performance of other companies.

d.Income tax effect of non-GAAP adjustments includes the income tax effects of the excluded items noted above.

e.Discrete tax items in the three months ended March 31, 2025 include a deferred tax impact relating to the amortization of certain intellectual property as a result of an internal restructuring of ownership rights to better align with how our business operates. Discrete tax items in the nine months ended March 31, 2025 also include the recognition of a deferred tax asset on foreign currency gains/losses resulting from new tax legislation. Discrete tax items in the nine months ended March 31, 2024 include a one-time tax benefit resulting from changes made to our international structure to better align ownership of certain intellectual property rights with how our business operates. Discrete tax items in all periods presented include a tax impact relating to the amortization of the aforementioned tax benefits or similar tax benefits recorded in other periods.
