The increase in Product Test revenues of $8.2 million, or 10.2%, was driven by higher Defense/Aerospace sales. The decrease in Robotics revenues of $13.6 million, or 15.3%, was primarily due to lower sales of collaborative robotic arms. Revenues by country as a percentage of total revenues were as follows (1): For the Three Months Ended September 28, 2025 September 29, 2024 Taiwan 37 % 26 % China 17 13 United States 12 12 Korea 12 26 Europe 7 8 Malaysia 5 2 Philippines 3 2 Thailand 3 2 Japan 1 2 Singapore 1 2 Rest of World 2 5 100 % 100 % (1) Revenues attributable to a country are based on location of customer site. Gross Profit Our gross profit was as follows: For the Three Months Ended September 28, 2025 September 29, 2024 Dollar/Point Change (in millions) Gross profit $ 449.3 $ 436.5 $ 12.8 Percent of total revenues 58.4 % 59.2 % (0.8 ) Gross profit as a percent of revenue decreased by 0.8 points, primarily due to product mix in Semiconductor Test. 34 Selling and Administrative Selling and administrative expenses were as follows: For the Three Months Ended September 28, 2025 September 29, 2024 Dollar Change (in millions) Selling and administrative $ 169.1 $ 157.6 $ 11.5 Percent of total revenues 22.0 % 21.4 % The increase of $11.5 million in selling and administrative expenses was primarily driven by strategic investments in Semiconductor Test. Engineering and Development Engineering and development expenses were as follows: For the Three Months Ended September 28, 2025 September 29, 2024 Dollar Change (in millions) Engineering and development $ 124.8 $ 117.5 $ 7.3 Percent of total revenues 16.2 % 15.9 % The increase of $7.3 million in engineering and development expenses was primarily driven by strategic investments in Semiconductor Test. Restructuring and Other During the three months ended September 28, 2025, we recorded $4.8 million of severance charges, $3.6 million of which is related to headcount reductions in Robotics. During the three months ended September 28, 2025, we made $1.1 million of Robotics severance payments. We expect all Robotics severance payments to be made prior to the end of the third quarter of 2026. During the three months ended September 29, 2024, we recorded restructuring and other charges primarily related to $1.3 million of severance charges related to headcount reductions principally in Robotics. Interest and Other For the Three Months Ended September 28, 2025 September 29, 2024 Dollar Change (in millions) Interest income $ (3.2 ) $ (5.1 ) $ 1.9 Interest expense 1.3 0.8 $ 0.5 Other (income) expense, net (0.9 ) (2.7 ) $ 1.8 The decrease in interest income was driven primarily by lower cash balances in the current period. 35 Income (Loss) Before Income Taxes and Equity in Net Earnings of Affiliate For the Three Months Ended September 28, 2025 September 29, 2024 Dollar Change (in millions) Semiconductor Test $ 150.8 $ 167.4 $ (16.6 ) Product Test 15.9 13.2 2.7 Robotics (17.6 ) (24.2 ) 6.6 Corporate and Eliminations (1) (1.1 ) 2.6 (3.7 ) $ 148.1 $ 159.0 $ (10.9 ) (1) Included in Corporate and Eliminations are interest income, interest expense, net foreign exchange gains (losses), intercompany eliminations, severance charges, pension and postretirement plan actuarial gains (losses), acquisition and divestiture related expenses, and gain on sale of business. The decrease in income before income taxes and equity in net earnings of affiliate in Semiconductor Test was driven primarily by product mix and investments in strategic projects partially offset by higher volume. The increase in income before income taxes and equity in net earnings of affiliate in Robotics was primarily due to lower operating expenses primarily as a result of restructuring actions. Income Taxes The effective tax rate for the three months ended September 28, 2025, and September 29, 2024, was 15.8% and 7.8%, respectively. The increase in the effective tax rate from the three months ended September 29, 2024, to the three months ended September 28, 2025, is primarily attributable to decreases in benefits related to reserves for uncertain tax positions, tax credits and the international provision of the U.S. Tax Cuts and Jobs Act of 2017. These were partially offset by an increase in benefit from a projected shift in the geographic distribution of income. Nine Months 2025 Compared to Nine Months 2024 Revenues Revenues by our reportable segments were as follows: For the Nine Months Ended September 28, 2025 September 29, 2024 Dollar Change (in millions) Semiconductor Test $ 1,640.2 $ 1,563.2 $ 77.0 Product Test 247.5 237.2 10.3 Robotics 218.9 266.6 (47.7 ) $ 2,106.7 $ 2,067.0 $ 39.7 The increase in Semiconductor Test revenues of $77.0 million, or 4.9%, was driven primarily by higher sales in mobility and compute related to artificial intelligence applications. The decrease in Robotics revenues of $47.7 million, or 17.9%, was primarily due to lower sales of collaborative robotic arms. The increase in Product Test revenues of $10.3 million, or 4.3%, was primarily due to higher sales in Wireless Test. 36 Revenues by country as a percentage of total revenues were as follows (1): For the Nine Months Ended September 28, 2025 September 29, 2024 Taiwan 33 % 20 % China 17 11 United States 12 13 Korea 10 28 Europe 7 9 Malaysia 4 2 Philippines 4 2 Singapore 4 2 Japan 2 7 Thailand 2 2 Rest of World 5 4 100 % 100 % (1) Revenues attributable to a country are based on location of customer site.

During the nine months ended September 28, 2025, we made $9.2 million of Robotics severance payments. We expect all Robotics severance payments to be made prior to the end of the third quarter of 2026. Additionally, we recorded $2.0 million of acquisition and divestiture expenses related primarily to the Quantifi Acquisition and $1.5 million of charges related to lease terminations. During the nine months ended September 29, 2024, we recorded restructuring and other charges primarily related to $5.3 million of severance and other charges, related to headcount reductions of 87 people primarily in Robotics and Semiconductor Test, which included charges related to a voluntary early retirement program for employees meeting certain conditions, and $2.2 million of acquisition and divestiture expenses related to the Technoprobe transactions. Gain on Sale of Business During the nine months ended September 29, 2024, we recorded a gain of $57.5 million associated with the sale of DIS to Technoprobe.

In the period ended September 29, 2024, other (income) expense, net included the change in value of our call option purchased in connection with the acquisition of Technoprobe. The call option expired on May 23, 2024. Income (Loss) Before Income Taxes and Equity in Net Earnings of Affiliate For the Nine Months Ended September 28, 2025 September 29, 2024 Dollar Change (in millions) Semiconductor Test $ 402.4 $ 408.0 $ (5.6 ) Product Test 40.1 42.9 (2.8 ) Robotics (73.3 ) (56.1 ) (17.2 ) Corporate and Eliminations (1) (5.5 ) 56.4 (61.9 ) $ 363.7 $ 451.3 $ (87.6 ) (1) Included in Corporate and Eliminations are gain on sale of business, interest income, interest expense, net foreign exchange gains (losses), intercompany eliminations, severance charges, pension and postretirement plan actuarial gains (losses), acquisition and divestiture related expenses, and gain on sale of business. The decrease in income before income taxes and equity in net earnings of affiliate in Semiconductor Test was driven primarily by higher spending in selling and administrative and engineering and development, partially offset by higher sales in mobility and compute for artificial intelligence applications. The decrease in income before income taxes and equity in net earnings of affiliate in Robotics was primarily due to lower sales of collaborative robotic arms, partially offset by lower operating expenses. The decrease in income before income taxes and equity in net earnings of affiliate in Product Test was primarily due to strategic investments. 38 Income Taxes The effective tax rate for the nine months ended September 28, 2025, and September 29, 2024, was 13.8% and 12.0%, respectively. The increase in the effective tax rate from the nine months ended September 29, 2024, to the nine months ended September 28, 2025, is primarily attributable to decreases in benefits related to reserves for uncertain tax positions and tax credits partially offset by an increase in benefit from a projected shift in the geographic distribution of income. Contractual Obligations There have been no changes outside of the ordinary course of business to our contractual obligations as disclosed in our Annual Report on Form 10-K for the year ended December 31, 2024. Liquidity and Capital Resources Our cash, cash equivalents and marketable securities balances decreased by $296.4 million in the nine months ended September 28, 2025, to $427.4 million. Operating activities during the nine months ended September 28, 2025, provided cash of $392.8 million. Changes in operating assets and liabilities used cash of $48.6 million due to a $169.0 million increase in operating assets and a $120.5 million increase in operating liabilities. The increase in operating assets was primarily due to increases in accounts receivable, inventories, and prepayments and other assets of $111.8 million, $34.6 million, and $22.6 million, respectively. The increase in operating liabilities was due to increases in accounts payable and other liabilities and in deferred revenue and customer advances of $121.4 million and $25.7 million, respectively, partially offset by decreases in income taxes and retirement plans of $19.7 million and $7.0 million, respectively. Investing activities during the nine months ended September 28, 2025, used cash of $307.7 million due to $161.1 million used for the purchase of property, plant & equipment, $144.4 million used for the acquisition of businesses, $27.5 million used for the purchase of marketable securities, and $25.5 million used for the purchase of investments in businesses, partially offset by $41.6 million and $9.2 million in proceeds from the maturities and sales of marketable securities, respectively.

Operating activities during the nine months ended September 29, 2024, provided cash of $389.6 million. Changes in operating assets and liabilities used cash of $75.8 million due to a $7.3 million decrease in operating assets and a $83.1 million decrease in operating liabilities. The decrease in operating assets was primarily due to decreases in other assets and inventory of $61.4 million and $11.1 million, respectively, partially offset by a $65.3 million increase in accounts receivable, driven by higher sales in the third quarter. The decrease in operating liabilities was due to a $32.3 million decrease in accrued employee compensation, $25.9 million decrease in accounts payable, $18.9 million decrease in income taxes, $4.2 million decrease in retirement plans, and $5.5 million decrease in accrued other, partially offset by a $3.6 million increase in deferred revenue and customer advances.

In January 2025, May 2025 and August 2025, our Board of Directors declared a quarterly cash dividend of $0.12 per share. Dividend payments for the three and nine months ended September 28, 2025, were $19.0 million and $57.6 million, respectively. In January 2024, May 2024, and August 2024, our Board of Directors declared a quarterly cash dividend of $0.12 per share. Dividend payments for the three and nine months ended September 29, 2024, were $19.6 million and $57.0 million, respectively. During the nine months ended September 28, 2025, we repurchased 5.1 million shares of common stock for $518.7 million, which excludes related excise tax, at an average price of $102.01 per share. We intend to repurchase up to $1.0 billion of common stock in 2025 and 2026, subject to market conditions. The cumulative repurchases under the 2023 repurchase program as of September 28, 2025, were 10.8 million shares of common stock for $1,113.8 million, which excludes related excise tax, at an average price per share of $104.21. During the nine months ended September 29, 2024, we repurchased 0.5 million shares of common stock for $55.1 million, which excludes related excise tax, at an average price of $111.32 per share. While we have previously declared a quarterly cash dividend and authorized a share repurchase program, we may reduce or eliminate the cash dividend or share repurchase program in the future. Cash dividends and stock repurchases are subject to the discretion of our Board of Directors, which will consider, among other things, our earnings, capital requirements and financial condition. On May 1, 2020, we entered into a credit agreement (the "Credit Agreement") providing a three-year, senior secured revolving credit facility of $400.0 million. On December 10, 2021, the Credit Agreement was amended to extend the senior secured revolving credit facility to December 10, 2026. On October 5, 2022, the Credit Agreement was amended to increase the amount of the credit facility to $750.0 million from $400.0 million. On November 7, 2023, the Credit Agreement was amended to allow for the purchase of the shares of Technoprobe. On September 4, 2025, and September 19, 2025, we borrowed a combined $200.0 million under the Credit Agreement to fund out capital allocation strategy. As of October 30, 2025, there is $250.0 million outstanding from the Credit Facility. We believe our cash, cash equivalents, marketable securities and senior secured revolving credit facility will be sufficient to pay our quarterly dividend and meet our working capital and expenditure needs for at least the next twelve months. Inflation has not had a significant long-term impact on earnings. As of September 28, 2025, we were in compliance with all covenants under the Credit Agreement. Equity Compensation Plans In addition to our 1996 Employee Stock Purchase Program as discussed in Note M: “Stock-Based Compensation” in our 2024 Annual Report on Form 10-K, we have a 2006 Equity and Cash Compensation Incentive Plan (the “2006 Equity Plan”). The purpose of the 1996 Employee Stock Purchase Plan is to encourage stock ownership by all eligible employees of Teradyne. The purpose of the 2006 Equity Plan is to provide equity ownership and compensation opportunities in Teradyne to our employees, officers and directors. Both plans were approved by our shareholders. Recently Issued Accounting Pronouncements In December 2023, the FASB issued ASU 2023-09 – “Income Taxes (Topic 740): Improvements to Income Tax Disclosures” , which requires expanded disclosures relating to the tax rate reconciliation, income taxes paid, income (loss) before income tax expense (benefit) and income tax expense (benefit), requiring a greater disaggregation of information for each. The provisions of ASU 2023-09 are effective for fiscal years beginning after December 15, 2024. We will apply the amendments in this update on a prospective basis. This ASU will have no impact on results of operations, cash flows or financial condition. In November 2024, the FASB issued ASU 2024-03- "Income Statement - Reporting Comprehensive Income -Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses" , which requires disclosure of additional expense information on an annual and interim basis, including the amounts of inventory purchases, employee compensation, depreciation and intangible amortization included within each income statement expense caption. This standard is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The amendments in this update should be applied on a prospective basis, but retrospective application is permitted. We are currently evaluating the impact of this new standard. 40 In July 2025, the FASB issued ASU 2025-05 - "Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses for Accounts Receivable and Contract Assets" , which introduces a practical expedient related to the estimation of expected credit losses for current accounts receivable and current contract assets that arise from transactions accounted for under ASC 606. The practical expedient permits all entities to assume that current conditions as of the balance sheet date do not change for the remaining life of the asset. This standard is effective for fiscal years beginning after December 15, 2025, with early adoption permitted. The amendments in this update should be applied on a prospective basis, but retrospective application is permitted. We are currently evaluating the impact of this new standard and do not expect a material impact on the financial statements and related disclosures. Item 3: Quantitative and Qualitative Disclosures about Market Risks For “Quantitative and Qualitative Disclosures about Market Risk” affecting Teradyne, see Part 2 Item 7A, “Quantitative and Qualitative Disclosures about Market Risks,” in our Annual Report on Form 10-K filed with the SEC on February 20, 2025. There were no material changes in our exposure to market risk from those set forth in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024. Item 4: Controls and Procedures As of the end of the period covered by this report, our management, with the participation of our Chief Executive Officer and Chief Financial Officer, evaluated the effectiveness of our disclosure controls and procedures pursuant to Rule 13a-15(b) or Rule 15d-15(f) promulgated under the Exchange Act. Based upon that evaluation, our Chief Executive Officer and Chief Financial Officer concluded that, as of the end of the period covered by this report, our disclosure controls and procedures were effective in ensuring that material information required to be disclosed in the reports that we file or submit under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms, including ensuring that such material information is accumulated and communicated to our management, including our Chief Executive Officer and Chief Financial Officer, as appropriate to allow timely decisions regarding required disclosure. There have been no changes in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d-15(f) under the Exchange Act) during the three months ended September 28, 2025, that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. 41 PART II. OTHER INFORMATION Item 1: Legal Proceedings We are subject to various legal proceedings and claims which have arisen in the ordinary course of business such as, but not limited to, patent, employment, commercial and environmental matters. Teradyne believes that it has meritorious defenses against all pending claims and intends to vigorously contest them. While it is not possible to predict or determine the outcomes of any pending claims or to provide possible ranges of losses that may arise, Teradyne believes the potential losses associated with all of these actions are unlikely to have a material adverse effect on its business, financial position or results of operations. Item 1A: Risk Factors In addition to other information set forth in this Form 10-Q, including the risk discussed below, you should carefully consider the factors discussed in Part I, “Item 1A: Risk Factors” in our Annual Report on Form 10-K for the year ended December 31, 2024, filed with the SEC on February 20, 2025, which could materially affect our business, financial condition or future results. The risk factors described in our Annual Report on Form 10-K for the fiscal year ended December 31, 2024, remain applicable to our business. The risks described in our Annual Report on Form 10-K are not the only risks that we face. Additional risks and uncertainties not currently known to us or that we currently deem to be immaterial also may materially adversely affect our business, financial condition and/or operating results. 42 Item 2: Unregistered Sales of Equity Securities and Use of Proceeds In January 2023, Teradyne’s Board of Directors cancelled our 2021 repurchase program and approved a new repurchase program for up to $2.0 billion of common stock. During the nine months ended September 28, 2025, we repurchased 5.1 million shares of common stock for a total cost of $523.5 million at an average price of $102.01 per share. We record share repurchases at cost, which includes broker commissions and related excise taxes. During the nine months ended September 29, 2024, we repurchased 0.5 million shares of common stock for $55.1 million at an average price of $111.32 per share.
