NORTH READING, Mass. – January 25, 2017 –Teradyne, Inc. (NYSE: TER) reported revenue of $380 million for the fourth quarter of 2016 of which $271 million was in Semiconductor Test, $50 million in System Test, $34 million in Industrial Automation, and $26 million in Wireless Test. GAAP net income for the fourth quarter was $66.3 million or $0.33 per share. On a non-GAAP basis, Teradyne’s net income in the fourth quarter was $64.6 million, or $0.32 per diluted share, which excluded acquired intangible asset amortization, pension actuarial gains, restructuring and other charges, non-cash convertible debt interest, discrete income tax adjustments, and included the related tax impact on non-GAAP adjustments.

Orders in the fourth quarter of 2016 were $628 million of which $524 million were in Semiconductor Test, $47 million in System Test, $34 million in Industrial Automation, and $23 million in Wireless Test.

“We closed 2016 with record fourth quarter orders as tester demand for 2017 mobile device production pulled bookings into Q4, automotive device test demand remained strong, and Universal Robots delivered another quarter of record orders,” said CEO and President Mark Jagiela. “For the full year, we grew company revenue 7%, non-GAAP earnings per share 19%, and returned $195 million to shareholders through share repurchases and dividends.

“As we look into 2017, we expect continued steady demand in our core test businesses and greater than 50% growth to continue at Universal Robots. On the capital return front, our proven operating model, strong balance sheet and positive long term outlook support our plan to repurchase a minimum of $200 million of Teradyne shares in 2017 and increase the dividend to $0.07 per quarter.”

Teradyne’s Board of Directors declared a quarterly cash dividend of $0.07 per share, payable on March 20, 2017 to shareholders of record as of the close of business on February 24, 2017.

Guidance for the first quarter of 2017 is revenue of $420 million to $450 million, with GAAP net income of $0.28 to $0.34 per diluted share and non-GAAP net income of $0.33 to $0.40 per diluted share. Non-GAAP guidance excludes acquired intangible asset amortization, non-cash convertible debt interest and includes the related tax impact on non-GAAP adjustments.

Non-GAAP Results

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 exclude goodwill and intangible asset impairment charges, acquired intangible asset amortization, non-cash convertible debt interest, pension actuarial gains and losses, fair value inventory step-up related to Universal Robots, discrete income tax adjustments, restructuring and other, and a gain from the sale of an equity investment. 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 and 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 gross margin excludes inventory step-up and pension actuarial gains and losses. GAAP requires that these items be included in determining gross margin. Non-GAAP gross margin dollar amount and percentage are non-GAAP performance measures that management believes provide useful supplemental information for management and the investor. Management uses non-GAAP gross margin as a performance measure for Teradyne’s current core business and future outlook and for comparison with Teradyne’s business plan, historical gross margin results and the gross margin 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.
