KLA Corporation Reports Fiscal 2027 First Quarter Results

•Total revenues were $4.14 billion, above the midpoint of the guidance range of $4.0 billion +/- $200 million;

•GAAP diluted EPS was $1.18 and non-GAAP diluted EPS was $1.22, both above the midpoints of the respective guidance ranges;

•Cash flow from operating activities for the quarter and last twelve months were $1.53 billion and $4.51 billion, respectively, and free cash flow was $1.34 billion and $4.04 billion, respectively; and

•Capital returns for the quarter and last twelve months were $1.24 billion and $3.79 billion, respectively.

MILPITAS, Calif., October 28, 2026 - KLA Corporation (NASDAQ: KLAC) today announced financial and operating results for its first quarter of fiscal year 2027, which ended on September 30, 2026, and reported GAAP net income of $1.55 billion and GAAP net income per diluted share of $1.18 on revenues of $4.14 billion.

“KLA’s September quarter beat the midpoint of guidance across all key metrics, demonstrating the accelerated growth we expected for the second half of calendar 2026,” said Rick Wallace, president and CEO of KLA Corporation. “Process control, and KLA in particular, continues to be critical to the AI ecosystem buildout and benefits from numerous ongoing inflections, including increases in leading-edge designs across foundry and logic, device size and value, memory complexity and performance requirements, and the importance of advanced packaging. In addition, KLA’s process, PCB, and component inspection businesses are benefiting from the technology transitions and the rigorous performance requirements of high-performance computing, which further augments the company’s growth profile. KLA’s market-leading product portfolio and its associated services offerings remain well positioned to address these compelling opportunities as we approach the end of calendar 2026 and look forward to calendar 2027.”

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. Acquisition-related charges during the three months ended June 30, 2026 also include a discrete release of $11.6 million of interest on unrecognized tax positions recorded as part of purchase price accounting arising from acquisitions. 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.Income tax effect of non-GAAP adjustments includes the income tax effects of the excluded items noted above.

c.Pillar Two undertaxed profits rule taxes represents the impact of Undertaxed Profits Rule taxes arising from Pillar Two legislation. We expect these taxes to be temporary and reverse upon adoption of the Side-by-Side Safe Harbor provisions, which would exempt U.S.-parented groups from the Undertaxed Profits Rule.

d.Discrete tax items in the three months ended September 30, 2025 include the recognition of a deferred tax liability for withholding taxes on future remittance of previously taxed income as a result of new tax legislation. Discrete tax items in all periods presented include a tax impact relating to the amortization of tax benefits from internal restructuring or similar tax benefits recorded in other periods.
