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 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 attributable to KLA, non-GAAP net income per diluted share attributable to KLA, 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 attributable to KLA to non-GAAP net income attributable to KLA:
a.Acquisition-related charges primarily include amortization of intangible assets and other acquisition-related adjustments including adjustments for the fair valuation of inventory and backlog, and transaction costs associated with our acquisitions, primarily Orbotech.
b.Restructuring, severance and other charges primarily include costs associated with employee severance, acceleration of certain stock-based compensation arrangements, and other exit costs.
c.Goodwill impairment included non-cash expense recognized as a result of KLA’s annual testing for goodwill impairment performed in the third quarter of the prior fiscal year. The impairment charge resulted from the downward revision of financial outlook for the acquired Orbotech business as well as the impact of elevated risk and macroeconomic slowdown driven by the COVID-19 pandemic.
8


d.Loss on extinguishment of debt included a pre-tax loss on early extinguishment of the $500 million 4.125% Senior Notes due in November 2021.
e.Income tax effect of non-GAAP adjustments includes the income tax effects of the excluded items noted above.
f.Discrete tax items in the three and twelve months ended June 30, 2021 include tax expense from an increase in deferred tax liability on purchased intangibles relating to an increase in the United Kingdom statutory income tax rate, partially offset by a net tax benefit from an internal restructuring and a reduction in unrecognized tax benefits. Discrete tax items in the three months ended March 31, 2021 primarily relate to a tax benefit due to a decrease in deferred tax liability on purchased intangibles relating to a decrease in the effective income tax rate in Israel. Discrete tax items in the three months and twelve months ended June 30, 2020 include a tax benefit from an internal restructuring and a decrease in deferred tax liability for an unrealized gain on investments held for sale by subsidiaries of the acquired Orbotech business.
