Teradyne Reports Fourth Quarter and Fiscal Year 2023 Results

NORTH READING, Mass. – January 30, 2024 – Teradyne, Inc. (NASDAQ: TER) reported revenue of $671 million for the fourth quarter of 2023 of which $431 million was in Semiconductor Test, $86 million in System Test, $25 million in Wireless Test and $129 million in Robotics. GAAP net income for the fourth quarter was $117 million or $0.72 per diluted share. On a non-GAAP basis, Teradyne’s net income in the fourth quarter was $127 million, or $0.79 per diluted share, which excluded pension actuarial losses, acquired intangible asset amortization, restructuring and other charges, and included the related tax impact on non-GAAP adjustments.

“We closed out 2023 with Q4 revenue and profit in line with our guidance as strong demand for memory test systems and 50% quarterly growth of Robotics revenue offset weakening demand for System-on-a-Chip (SOC) test systems,” said Teradyne CEO Greg Smith. “Looking into the new year, we expect low tester utilization will impact demand in the first half of the year but anticipate the full year Semiconductor test demand to incrementally improve from 2023. In Robotics, after expected seasonal weakness in Q1, we project consistent quarterly growth powered by new products, new applications and improvements in our global distribution channels.”

Guidance for the first quarter of 2024 is revenue of $540 million to $590 million, with GAAP net income of $0.19 to $0.35 per diluted share and non-GAAP net income of $0.22 to $0.38 per diluted share. Non-GAAP guidance excludes acquired intangible asset amortization and includes the related tax impact on non-GAAP adjustments.

Non-GAAP income from operations and non-GAAP net income exclude acquired intangible assets amortization, restructuring and other, pension actuarial gains and losses, stock compensation modification expense, discrete income tax adjustments, and includes 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. Non-GAAP diluted shares include the impact of Teradyne’s call option on its shares. 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.
