NOTES TO CONDENSED CONSOLI DATED FINANCIAL STATEMENTS (In thousands, except per share data and percentages) (Unaudited) NOTE 1. Basis of Presentation The accompanying interim unaudited Condensed Consolidated Financial Statements have been prepared by Onto Innovation Inc. (together with its consolidated subsidiaries, unless otherwise specified or suggested by the context, the “Company,” “Onto Innovation,” “we,” “our” or “us”) and in the opinion of management reflect all adjustments, consisting of normal recurring accruals, necessary for their fair presentation in accordance with accounting principles generally accepted in the United States of America (“U.S. GAAP”). Preparing financial statements requires management to make estimates and assumptions that affect amounts reported in the financial statements and accompanying notes. Actual amounts could differ materially from reported amounts. The interim results for the three months ended March 30, 2024 are not necessarily indicative of results to be expected for the entire year or any future periods. This interim financial information should be read in conjunction with the financial statements and the notes thereto included in the Company’s Annual Report on Form 10-K for the year ended December 30, 2023 (the “2023 Form 10-K”) filed with the Securities and Exchange Commission on February 26, 2024. The accompanying Condensed Consolidated Balance Sheet at December 30, 2023 has been derived from the audited consolidated financial statements included in the 2023 Form 10-K. The Company operates on a 52- or 53-week fiscal year ending on the Saturday closest to December 31. Our fiscal year ending December 28, 2024 (“fiscal year 2024”) is a 52-week fiscal year. The first quarter of the Company’s fiscal year 2024 ended on March 30, 2024, the second quarter ends on June 29, 2024 and the third quarter ends on September 28, 2024. Our fiscal year ended December 30, 2023 was a 52-week fiscal year. The first quarter of the fiscal year ended December 30, 2023 ended on April 1, 2023. Use of Estimates The preparation of financial statements in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities as of the date of the financial statements and the reported amounts of revenue and expenses during the reporting period. Estimates made by management include excess and obsolete inventory, fair value of assets acquired and liabilities assumed in a business combination, recoverability and useful lives of property, plant and equipment and identifiable intangible assets, recoverability of goodwill, recoverability of deferred tax assets, allowance for credit losses, liabilities for product warranty, share-based payments and liabilities for tax uncertainties. Actual results could differ from those estimates. These estimates and assumptions are based on historical experience and on various other factors which the Company believes to be reasonable under the circumstances. The Company may engage third-party valuation specialists to assist with estimates related to the valuation of financial instruments, assets and stock awards associated with various contractual arrangements. Such estimates often require the selection of appropriate valuation methodologies and significant judgment. Actual results could differ from these estimates under different assumptions or circumstances and such differences could be material. Adoption of Accounting Standards Recently Adopted or Effective There have been no recent accounting pronouncements or changes in accounting pronouncements during the three months ended March 30, 2024, as compared to the recent accounting pronouncements described in the Company’s Annual Report on Form 10-K for the fiscal year ended December 30, 2023, that are of significance, or potential significance to the Company. Updates Not Yet Effective In November 2023, the Financial Accounting Standards Board (“FASB”) issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures,” which expands disclosures about a public entity’s reportable segments and requires more enhanced information about a reportable segment’s expenses, interim segment profit or loss, and how a public entity’s chief operating decision maker uses reported segment profit or loss information 6 Table of Contents in assessing segment performance and allocating resources. The guidance is effective for financial statements issued for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company is required to adopt this standard in the fiscal year 2024 for the annual reporting period ending December 28, 2024, with retrospective disclosure of prior periods presented. The Company is currently in the process of evaluating the impact of adoption on its Consolidated Financial Statements. In December 2023, the FASB issued ASU 2023-09, “Income Taxes (Topic 740): Improvements to Income Tax Disclosures,” which requires public entities to disclose consistent categories and greater disaggregation of information in the rate reconciliation and for income taxes paid. It also includes certain other amendments to improve the effectiveness of income tax disclosures. The guidance is effective for financial statements issued for annual periods beginning after December 15, 2024, with early adoption permitted. The Company is required to adopt this standard prospectively in fiscal year 2025 for the annual reporting period ending December 27, 2025. The Company is currently in the process of evaluating the impact of adoption on its Consolidated Financial Statements. NOTE 2. Fair Value Measurements Fair Value of Financial Instruments The Company has evaluated the estimated fair value of financial instruments using available market information and valuations as provided by third-party sources. The use of different market assumptions and/or estimation methodologies could have a significant effect on the estimated fair value amounts. The carrying value of cash and cash equivalents, accounts receivable, accounts payable and accrued liabilities approximates fair value because of the short-term maturity of these instruments. Fair Value Hierarchy The Company applies a three-level valuation hierarchy for fair value measurements. This hierarchy prioritizes the inputs into three broad levels. Level 1 inputs are quoted prices (unadjusted) in active markets for identical assets or liabilities. Level 2 inputs are quoted prices for similar assets and liabilities in active markets or inputs that are observable for the asset or liability, either directly or indirectly through market corroboration, for substantially the full term of the asset or liability. Level 3 inputs are unobservable inputs based on management’s assumptions used to measure assets and liabilities at fair value. A financial asset’s or liability’s fair value measurement classification within the hierarchy is determined based on the lowest level input that is significant to the fair value measurement. The following tables provide the assets and liabilities carried at fair value measured on a recurring basis at March 30, 2024 and December 30, 2023: Fair Value Measurements Using Significant Other Observable Inputs (Level 2) March 30, 2024 December 30, 2023 Assets: Available-for-sale debt securities: Government notes and bonds $ 248,929 $ 195,800 Certificates of deposit 54,821 67,467 Commercial paper 123,344 99,635 Corporate bonds 122,944 101,401 Foreign currency forward contracts 202 — Total assets $ 550,240 $ 464,303 Liabilities: Foreign currency forward contracts $ — $ 1,370 Total Liabilities $ — $ 1,370 Available-for-sale debt securities classified as Level 2 are valued using observable inputs to quoted market prices, benchmark yields, reported trades, broker/dealer quotes or alternative pricing sources with reasonable levels of price transparency. The foreign currency forward contracts are primarily measured based on the foreign currency spot and forward 7 Table of Contents rates quoted by the banks or foreign currency dealers. Investment prices are obtained from third party pricing providers, which model prices utilizing the above observable inputs, for each asset class. See Note 3 for additional discussion regarding the fair value of the Company’s marketable securities. NOTE 3. Marketable Securities At March 30, 2024 and December 30, 2023, marketable securities are categorized as follows: Amortized Cost Gross Unrealized Holding Gains Gross Unrealized Holding Losses Fair Value March 30, 2024 Government notes and bonds $ 249,211 $ 90 $ 373 $ 248,928 Certificates of deposit 54,800 37 15 54,822 Commercial paper 123,380 15 50 123,345 Corporate bonds 122,896 177 130 122,943 Total marketable securities $ 550,287 $ 319 $ 568 $ 550,038 December 30, 2023 Government notes and bonds $ 195,733 $ 393 $ 326 $ 195,800 Certificates of deposit 67,377 93 3 67,467 Commercial paper 99,591 54 10 99,635 Corporate bonds 101,146 391 136 101,401 Total marketable securities $ 463,847 $ 931 $ 475 $ 464,303 The amortized cost and estimated fair value of marketable securities classified by the maturity date listed on the security, regardless of the Condensed Consolidated Balance Sheets classification, is as follows at March 30, 2024 and December 30, 2023: March 30, 2024 December 30, 2023 Amortized Cost Fair Value Amortized Cost Fair Value Due within one year $ 355,655 $ 355,387 $ 331,136 $ 330,937 Due after one through five years 145,917 145,936 132,711 133,366 Due after five through ten years 115 115 — — Due after ten years 48,600 48,600 — — Total marketable securities $ 550,287 $ 550,038 $ 463,847 $ 464,303 The Company has evaluated its investment policies and determined that all of its marketable securities, which are comprised of debt securities, are to be classified as available-for-sale. The Company’s available-for-sale debt securities are carried at fair value, with the unrealized gains and losses reported in Stockholders’ equity under the caption “Accumulated other comprehensive loss.” Gross realized gains and losses on available-for-sale securities are included in “Other income (expense), net” on the Condensed Consolidated Statements of Operations and were not material during the three months ended March 30, 2024 and December 30, 2023. The Company records credit losses for its available-for-sale debt securities when it intends to sell the securities, it is more-likely-than not that it will be required to sell the securities before a recovery, or when it does not expect to recover the entire amortized cost basis of the securities. The cost of securities sold is based on the specific identification method. The Company has determined that the gross unrealized losses on its marketable securities at March 30, 2024 and December 30, 2023 are temporary in nature. The Company regularly reviews its investment portfolio to identify and evaluate marketable securities that have indications of possible impairment from credit losses or other factors. Factors considered in determining whether an unrealized loss is considered to be a credit loss include the length of time and extent to which fair value has been less than the cost basis, credit quality and the Company’s ability and intent to hold the securities for a period of time sufficient to allow for any anticipated recovery in market value. 8 Table of Contents The following table summarizes the estimated fair value and gross unrealized holding losses of marketable securities, aggregated by investment instrument and period of time in an unrealized loss position, at March 30, 2024 and December 30, 2023: In Unrealized Loss Position For Less Than 12 Months In Unrealized Loss Position For Greater Than 12 Months Fair Value Gross Unrealized Losses Fair Value Gross Unrealized Losses March 30, 2024 Government notes and bonds $ 95,000 $ 200 $ 41,367 $ 173 Certificates of deposit 18,340 16 — — Commercial paper 88,615 50 — — Corporate bonds 48,457 98 6,270 31 Total $ 250,412 $ 364 $ 47,637 $ 204 December 30, 2023 Government notes and bonds $ 82,776 $ 325 $ 180 $ 1 Certificates of deposit 11,839 3 — — Commercial paper 20,121 10 — — Corporate bonds 20,268 103 5,999 33 Total $ 135,004 $ 441 $ 6,179 $ 34 See Note 2 for additional discussion regarding the fair value of the Company’s marketable securities. NOTE 4. Derivative Instruments and Hedging Activities The Company, when it considers it to be appropriate, enters into forward contracts to hedge the economic exposures arising from foreign currency denominated transactions. At March 30, 2024 and December 30, 2023, these contracts were denominated in euro, Chinese renminbi, Japanese yen, Korean won, Singapore dollars, and Taiwanese dollars. Foreign currency forward contracts are not designated as hedges for accounting purposes, and therefore, the change in fair value is recorded in “Other income (expense), net,” in the Condensed Consolidated Statements of Operations. The Company records its forward contracts at fair value in either prepaid expenses and other current assets or other current liabilities in the Condensed Consolidated Balance Sheets. The dollar equivalent of the U.S. dollar forward contracts and related fair values as of March 30, 2024 and December 30, 2023 were as follows: March 30, 2024 December 30, 2023 Notional amount $ 32,122 $ 51,551 Fair value of asset (liability) $ 202 $ ( 1,370 ) 9 Table of Contents NOTE 5.

Commitments and Contingencies Factoring The Company maintains arrangements under which eligible accounts receivable in Japan are sold without recourse to unrelated third-party financial institutions. The Company sold $ 3,447 of receivables during the three months ended March 30, 2024. These receivables were not included in the Condensed Consolidated Balance Sheets as the criteria for sale treatment had been met. There were no material gains or losses on the sale of such receivables. There were no amounts due from such third-party financial institutions at March 30, 2024. Intellectual Property Indemnification Obligations The Company has entered into agreements with customers that include limited intellectual property indemnification obligations that are customary in the industry. These guarantees generally require the Company to compensate the other party for certain damages and costs incurred as a result of third-party intellectual property claims arising from these transactions. The nature of the intellectual property indemnification obligations prevents the Company from making a reasonable estimate of the maximum potential amount it could be required to pay to its customers. Historically, the Company has not made any indemnification payments under such agreements and no amount has been accrued in the accompanying Condensed Consolidated Financial Statements with respect to these indemnification guarantees. Warranty Reserves The Company generally provides a warranty on its products for a period of 12 to 14 months against defects in material and workmanship. The Company estimates the costs that may be incurred during the warranty period and records a liability in the amount of such costs at the time revenue is recognized. The Company’s estimate is based primarily on historical experience. The Company periodically assesses the adequacy of its recorded warranty liabilities and adjusts the amounts as necessary. Warranty provisions are generally related to current period sales. Settlements of warranty reserves are generally associated with sales that occurred during the 12 to 14 months prior to the period-end. Changes in the Company’s warranty reserves are as follows: Three Months Ended March 30, April 1, 2024 2023 Balance, beginning of the period $ 9,380 $ 11,830 Accruals 2,761 2,551 Usage ( 2,903 ) ( 3,879 ) Balance, end of the period $ 9,238 $ 10,502 Warranty reserves are reported in the Condensed Consolidated Balance Sheets under the captions “Accrued liabilities” and “Other non-current liabilities.” Legal Matters From time to time, the Company is subject to legal proceedings and claims in the ordinary course of business. In the opinion of management, any potential liabilities resulting from any current disputes would not have a material adverse effect on the Company’s unaudited interim condensed consolidated financial statements. Line of Credit The Company has a credit agreement with a bank that provides for a line of credit which is secured by the marketable securities the Company has with the bank. The Company is permitted to borrow up to 70 % of the value of eligible securities held at the time the line of credit is accessed. The available line of credit as of March 30, 2024 was approximately $ 100 million with 12 Table of Contents an available interest rate of 7.1 %. The credit agreement is available to the Company until such time that either party terminates the arrangement at their discretion. The Company has not utilized the line of credit as of the date of this filing. NOTE 8. Revenue The following table represents a disaggregation of revenue by timing of revenue: Three Months Ended March 30, April 1, 2024 2023 Point-in-time $ 213,850 $ 186,374 Over-time 14,996 12,791 Total revenue $ 228,846 $ 199,165 See Note 14 for additional discussion of the Company’s disaggregated revenue in detail. Contract Liabilities The Company records contract liabilities when the customer has been billed in advance of the Company completing its performance obligations primarily with respect to liabilities related to service contracts and installation. For contracts that have a duration of one year or less, these amounts are recorded as current deferred revenue in the Condensed Consolidated Balance Sheets.

Share-Based Compensation Restricted Stock Unit Activity A summary of the Company’s restricted stock unit activity with respect to the three months ended March 30, 2024 is as follows: Number of Shares Weighted Average Grant Date Fair Value Nonvested at December 30, 2023 584 $ 85.41 Granted 84 $ 172.03 Vested ( 129 ) $ 79.37 Forfeited ( 3 ) $ 81.42 Nonvested at March 30, 2024 536 $ 100.50 Of the 536 nonvested shares outstanding at March 30, 2024, 454 are service-based RSUs and 82 are market-based PRSUs. The fair value of the Company’s service-based RSUs was calculated based on the fair market value of the Company’s stock at the date of grant. The fair value of the Company’s market-based PRSUs granted during fiscal years 2024 and 2023 was calculated 13 Table of Contents using a Monte Carlo simulation model at the date of the grant, resulting in a weighted average grant-date fair value per share of $ 251.51 and $ 100.79 , respectively. As of March 30, 2024 and December 30 2023, there was $ 32,081 and $ 26,559 of total unrecognized compensation cost related to restricted stock units granted under the Company’s stock plans, respectively. That cost is expected to be recognized over a weighted average period of 1.5 years and 1.4 years for March 30, 2024 and December 30, 2023, respectively. NOTE 10. Other Income (Expense), Net Other income (expense), net, is comprised of the following: Three Months Ended March 30, April 1, 2024 2023 Foreign currency exchange gains (losses), net $ 642 $ ( 307 ) Other 151 26 Total other income (expense), net $ 793 $ ( 281 ) NOTE 11. Income Taxes The following table provides details of income taxes: Three Months Ended March 30, April 1, 2024 2023 Income before income taxes $ 50,892 $ 32,202 Provision for income taxes $ 4,039 $ 3,134 Effective tax rate 8 % 10 % The income tax provision for the three months ended March 30, 2024 was computed based on the Company’s annual forecast of profit by jurisdiction and forecasted effective tax rate for the year. The increase in the Company’s income tax provision for the three months ended March 30, 2024 as compared to the three months ended April 1, 2023 was primarily due to an increase in quarterly earnings, offset by an increase in the excess benefits associated with equity compensation. The Company’s recorded effective tax rate for the periods presented is less than the U.S. statutory rate primarily due to projected FDII deductions, federal research and development tax credits, and excess tax benefits associated with equity compensation. The Company currently has a partial valuation allowance recorded against certain foreign and state net operating loss and credit carryforwards where the realizability of such deferred tax assets is substantially in doubt. Each quarter, the Company assesses the likelihood that it will be able to recover its deferred tax assets. The Company considers available evidence, both positive and negative, including forecasted earnings, in assessing its need for a valuation allowance. As a result of the Company’s analysis, it concluded that it is more likely than not that a portion of its deferred tax assets will not be realized. Therefore, the Company continues to provide a valuation allowance against certain deferred tax assets. The Company continues to monitor available evidence and may reverse some or all of its remaining valuation allowance in future periods, if appropriate. The Company has a recorded valuation allowance against a certain portion of its deferred tax assets of $ 13,960 at March 30, 2024 and December 30, 2023. The Organization for Economic Co-operation and Development (“OECD”) has been working on a Base Erosion and Profits Shifting project that, upon implementation, would change various aspects of the existing framework under which the Company’s tax obligations are determined in many of the countries in which we operate. In this regard, the OECD has proposed policies aiming to modernize global tax systems, including a country-by-country 15% minimum effective tax rate (“Pillar Two”) for multinational companies. Numerous countries have enacted, or are in the process of enacting, legislation to implement the Pillar Two model rules with a subset of the rules becoming effective during the current year, and the remaining rules becoming effective in later periods. At this point in time, the Company does not expect any material tax impact associated with Pillar Two rules in the countries where it operates. As these rules continue to evolve with new legislation and guidance, the Company will 14 Table of Contents continue to monitor and account for the enactment of Pillar Two and the potential impacts such rules may have on its effective tax rate and cash flows in future years.
