•GAAP diluted EPS was $6.16. Non-GAAP diluted EPS was $8.20, near the upper end of the guidance range. GAAP EPS was impacted by a $239.1 million impairment charge for goodwill and purchased intangible assets, or $1.76 per diluted share.

MILPITAS, Calif., January 30, 2025 - KLA Corporation (NASDAQ: KLAC) today announced financial and operating results for its second quarter of fiscal year 2025, which ended on December 31, 2024, and reported GAAP net income of $824.5 million and GAAP net income per diluted share of $6.16 on revenues of $3.08 billion.
“KLA’s December quarter results were above the midpoint of our guidance ranges despite navigating through the business impact of new U.S. government export controls released late in the quarter. These results supported a strong finish to calendar 2024 for KLA highlighted by relative revenue growth outperformance and strong profitability,” said Rick Wallace, president and CEO, KLA Corporation. “The return to growth at the leading-edge continues to gain momentum led by expanding AI and high-performance computing investments. KLA's differentiated portfolio of solutions aligns exceptionally well in helping enable our customers to navigate increasing technology complexity, growing design starts and larger semiconductor devices in an environment of rising semiconductor demand.”

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 three and six months ended December 31, 2024 as well as the three and six months ended December 31, 2023 included 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. 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.
8

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 and six months ended December 31, 2024 include the recognition of a deferred tax asset on foreign currency gains/losses resulting from new tax legislation. Discrete tax items in the three and six months ended December 31, 2023 included 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 included a tax impact relating to the amortization of the aforementioned tax benefit or similar tax benefits recorded in other periods.
