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 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, transaction costs associated with our acquisitions and dispositions, as well as intangible asset impairment charges. 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 including associated acceleration of recognition of certain stock-based and other compensation expenses, gains and losses from exiting non-core businesses and adjustments related to non-controlling interest. Restructuring, severance and other charges in the nine months ended March 31, 2023 included a gain on the sale of Orbograph, Ltd. (“Orbograph”), which was sold in the first quarter of fiscal 2023, partially offset by certain transaction bonuses triggered by the sale of Orbograph.
8

c.Impairment of goodwill and purchased intangible assets included non-cash expense recognized in the three months ended March 31, 2024 and December 31, 2023, following the downward revision of financial outlook for the PCB and Display reporting units in the second quarter of fiscal 2024 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. 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.Loss on extinguishment of debt during the nine months ended March 31, 2023 included a pre-tax loss on early extinguishment of the $500 million 4.650% Senior Notes due in November 2024.
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 nine months ended March 31, 2024 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. Discrete items in the nine months ended March 31, 2023 included an adjustment of the net benefit of the Orbotech Ltd. 2012 to 2018 Israel tax audit settlement, for which the net benefit includes the liability on the audit settlement less reductions in unrecognized tax positions and deferred tax assets and liabilities. Discrete tax items in the nine months ended March 31, 2023 also included a tax impact from the sale of Orbograph and a tax expense of $19.8 million from an internal restructuring.
