NORTH READING, Mass. – October 27, 2026 – Teradyne, Inc . (NASDAQ: TER) reported revenue of $1,306 million for the third quarter of 2026 of which $1,072 million was in Semiconductor Test, $138 million in Product Test, and $96 million in Robotics. On a GAAP-basis, net income attributable to Teradyne for the third quarter of 2026 was $342.4 million, or $2.17 per diluted share. On a non-GAAP basis, net income attributable to Teradyne for the third quarter of 2026 was $359.9 million, or $2.29 per diluted share, which excluded acquired intangible asset amortization, restructuring and other charges, and the related tax impact on non-GAAP adjustments. “Our wafer to data center strategy and the breadth of our portfolio sustained positive momentum in Q3,” said CEO Greg Smith. “Demand extended across the AI value chain, from memory and hard disk drive test to high-speed interconnect and robotics, driving results above the high end of our guidance. With multiple growth engines across test and robotics, we approach 2027 with a more diversified business and an expanding set of opportunities.” Guidance for the fourth quarter of 2026 is revenue of $1,250 million to $1,350 million, with GAAP net income attributable to Teradyne of $1.88 to $2.18 per diluted share and non-GAAP net income attributable to Teradyne of $1.95 to $2.25 per diluted share. Non-GAAP guidance excludes acquired intangible asset amortization and amortization on our investment in Technoprobe, as well as the related tax impact on non-GAAP adjustments.

In addition to disclosing results that are determined in accordance with GAAP, Teradyne also discloses non-GAAP results of operations that exclude certain income items and charges. These results are provided as a complement to results provided in accordance with GAAP. Non-GAAP income from operations and non-GAAP net income attributable to Teradyne excludes acquired intangible assets amortization, restructuring and other, ERP related expenses, inventory step-up, pension mark-to-market adjustment, pension actuarial gains and losses, discrete income tax adjustments, and the related tax impact on non-GAAP adjustments. GAAP requires that these items be included in determining income from operations and net income. Non-GAAP income from operations, non-GAAP net income, non-GAAP income from operations as a percentage of revenue, non-GAAP net income as a percentage of revenue, and non-GAAP net income per share are non-GAAP performance measures presented to provide meaningful supplemental information regarding Teradyne’s baseline performance before gains, losses or other charges that may not be indicative of Teradyne’s current core business or future outlook. These non-GAAP performance measures are used to make operational decisions, to determine employee compensation, to forecast future operational results, and for comparison with Teradyne’s business plan, historical operating results and the operating results of Teradyne’s competitors. Management believes each of these non-GAAP performance measures provides useful supplemental information for investors, allowing greater transparency to the information used by management in its operational decision making and in the review of Teradyne’s financial and operational performance, as well as facilitating meaningful comparisons of Teradyne’s results in the current period compared with those in prior and future periods.
