First Quarter Business and Financial Highlights:<\/b><\/p>\n \n\u201cWe are pleased to see the positive customer response to several key initiatives, including the success of our new Dragonfly\u00ae G5 inspection system, the accelerating adoption of our Atlas\u00ae G6 OCD system for next-generation logic and memory devices, and the ramp of our extended factories that are closer to our customers in Asia. Collectively, these achievements enable us to provide increased value to customers while supporting their aggressive ramp plans,\u201d said Mike Plisinski, chief executive officer of Onto Innovation. \u201cBy expanding our process control suite to include unique surface charge metrology through the Semilab USA acquisition and a broad portfolio of advanced X-ray technologies through our partnership with Rigaku, we strengthen our ability to address customers\u2019 challenges of today, while collaborating with them to develop the solutions for tomorrow.\u201d<\/p>\n Operating Results:<\/b><\/p>\n \nThe results for the three months ended March 31, 2026, include non-GAAP financial measures, each of which is defined and reconciled to the most directly comparable GAAP measure later in the press release.<\/p>\n Three months ended March 31, 2026:<\/b><\/p>\n Revenue and Gross Margin:<\/b><\/p>\n Operating Income:<\/b><\/p>\n Net Income and Earnings per share:<\/b><\/p>\n Cash and investments:<\/b><\/p>\n \nThe Company generated cash from operations of approximately $26 million for the first quarter of 2026.

There will be a replay of the conference call available for one year on the Company\u2019s website at www.ontoinnovation.com<\/a>.<\/p>\n Discussion of Non-GAAP Financial Measures<\/b><\/p>\n \nIn addition to information regarding the Company\u2019s results as determined in accordance with generally accepted accounting principles in the United States (\u201cGAAP\u201d), the Company has provided in this release non-GAAP financial measures, including non-GAAP gross profit as a percentage of revenue, non-GAAP operating income, non-GAAP operating expenses, non-GAAP net income, non-GAAP diluted earnings per share and non-GAAP operating margin as a percentage of revenue, which exclude amortization of intangibles, merger and acquisition-related expenses and benefits, litigation expenses and benefits and other restructuring costs. Non-GAAP gross margin as a percentage of revenue, non-GAAP operating income, non-GAAP operating expenses, non-GAAP net income, non-GAAP diluted earnings per share and non-GAAP operating margin as a percentage of revenue can also exclude certain other gains and losses that are either isolated or cannot be expected to occur again with any predictability or otherwise are not representative of our ongoing operations, tax provisions\/benefits related to the previous items, and significant discrete tax events. We exclude the above items because they are outside of our normal operations and\/or, in certain cases, are difficult to forecast accurately for future periods.<\/p>\n \nWe utilize several different financial measures, both GAAP and non-GAAP, in analyzing and assessing the overall performance of our business, in making operating decisions, forecasting and planning for future periods, and determining payments under compensation programs. We consider the use of the non-GAAP measures to be helpful in assessing the performance of the ongoing operations of our business. We believe that disclosing non-GAAP financial measures provides useful supplemental data that, while not a substitute for financial measures prepared in accordance with GAAP, allows for greater transparency in the review of our financial and operational performance. We also believe that disclosing non-GAAP financial measures provides useful information to investors and others in understanding and evaluating our operating results and future prospects in the same manner as management and in comparing financial results across accounting periods and to those of peer companies. More specifically, management adjusts for the excluded items for the following reasons:<\/p>\n Amortization of intangibles:<\/i> we do not acquire businesses and assets on a predictable cycle. The amount of purchase price allocated to the purchased intangible assets and the term of amortization can vary significantly and are unique to each acquisition or purchase. We believe that excluding amortization of purchased intangible assets allows the users of our financial statements to better review and understand the historic and current results of our operations and also facilitates comparisons to peer companies.<\/p>\n Merger or acquisition related expenses and benefits:<\/i> we incur expenses or benefits with respect to certain items associated with our mergers and acquisitions, such as transaction and integration costs, change in control payments, adjustments to the fair value of assets, etc. We exclude such expenses or benefits as they are related to acquisitions and have no direct correlation to the operation of our ongoing business.<\/p>\n Restructuring and other<\/i>: we incur restructuring and impairment charges on individual or groups of employed assets, such as inventory or plant, property & equipment, which arise from unforeseen circumstances and\/or often occur outside of the ordinary course of our ongoing business. Although these events are reflected in our GAAP financials, these transactions may limit the comparability of our ongoing operations with prior and future periods.<\/p>\n Litigation expenses and benefits:<\/i> we may incur charges or benefits as well as legal costs in connection with litigation and other contingencies unrelated to our core operations. We exclude these charges or benefits, when significant, as well as legal costs associated with significant legal matters, because we do not believe they are reflective of ongoing business and operating results.<\/p>\n Income tax expense:<\/i> we estimate the tax effect of the items identified to determine a non-GAAP annual effective tax rate applied to the pretax amount to calculate the non-GAAP provision for income taxes. We also adjust for items for which the nature and\/or tax jurisdiction requires the application of a specific tax rate or treatment.<\/p>\n \nFrom time to time in the future, there may be other items excluded if we believe that doing so is consistent with the goal of providing useful information to investors and management.<\/p>\n \nThere are limitations in using non-GAAP financial measures because the non-GAAP financial measures are not prepared in accordance with GAAP and may be different from non-GAAP financial measures used by other companies. The non-GAAP financial measures are limited in value because they exclude certain items that may have a material impact on our reported financial results. The presentation of this additional information is not meant to be considered in isolation or as a substitute for the directly comparable financial measures prepared in accordance with GAAP. Investors should review the reconciliation of the non-GAAP financial measures to their most directly comparable GAAP financial measures as provided in the tables accompanying this press release.<\/p>\n Forward Looking Statements<\/b><\/p>\n \nThis press release contains forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995 (the \u201cAct\u201d) which include, but are not limited to, statements regarding Onto Innovation\u2019s business momentum and future growth; technology development, product introduction and acceptance of Onto Innovation\u2019s products and services; Onto Innovation\u2019s manufacturing practices and ability to deliver both products and services consistent with its customers\u2019 demands and expectations and strengthen its market position; Onto Innovation\u2019s expectations regarding the semiconductor market outlook, including customers\u2019 potential expansion plans; Onto Innovation\u2019s future quarterly financial outlook; as well as other matters that are not purely historical data.
