Teradyne Announces Fourth Quarter and Fiscal Year Results

NORTH READING, Mass. — (BUSINESS WIRE)—January 24, 2007 — Teradyne, Inc. reported sales of $263 million for the fourth quarter of 2006. Net income in the fourth quarter was $10.9 million, or $0.06 per diluted share, and $11.6 million or $0.06 per diluted share on a non-GAAP basis. Bookings for the fourth quarter were $287.5 million.

For fiscal 2006, sales were $1.38 billion. Net income for the year was $198.8 million or $1.01 per diluted share. Net income for the year from continuing operations was $202.6 million, or $1.03 per diluted share and $171.6 million, or $0.88 per diluted share on a non-GAAP basis. Bookings for the year were $1.29 billion.

“Despite continued low demand in the semiconductor test market in the fourth quarter, our results for the year as a whole were very solid,” said Michael Bradley, Teradyne president and CEO. “Our 2006 semiconductor test revenues grew significantly faster than the market, our Systems Test Group had very good performance and we achieved record free cash flow for the year. However, System On a Chip (SOC) test customers remain very cautious in the near-term as they digest their 2006 capacity additions.”

Sales in the first quarter of 2007 are expected to be between $245 million and $260 million, with earnings per diluted share between $0.00 and $0.03.

During the fourth quarter of 2006, Teradyne repurchased 2.1 million shares of its common stock for $28 million under its previously announced Stock Repurchase Program, bringing the total number of shares of common stock repurchased in fiscal 2006 to 10.6 million, for a total of $138 million.

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. Teradyne reports non-GAAP results in order to better assess and reflect operating performance. Management believes the non-GAAP measures help indicate Teradyne’s baseline performance before gains, losses or other charges that are considered by management to be outside Teradyne’s ongoing operating results. Teradyne believes these non-GAAP measures will aid investors’ overall understanding of its results by providing a higher degree of transparency for certain expenses and providing a level of disclosure that will help investors understand how Teradyne plans and measures its own business. A reconciliation of each GAAP to non-GAAP financial measure discussed in this press release is contained in the attached Exhibits and on the Teradyne website atwww.teradyne.com by clicking on “Investors” and then selecting the “GAAP to Non-GAAP Reconciliation” link. The presentation of non-GAAP measures is not meant to be

considered in isolation, as a substitute for, or superior to, financial measures or information provided in accordance with GAAP.

Safe Harbor Statement

The forward-looking statements included in this release are made only as of the date of publication and Teradyne undertakes no obligation to update the information set forth in this release.

This release contains forward-looking statements regarding expected future revenues and earnings, future market conditions and business prospects. Such statements are based on the current assumptions and expectations of Teradyne’s management and are neither promises nor guarantees. You can generally identify these forward-looking statements based on the context of the statements and by the fact that they use words such as “will,” “anticipate,” “expect,” “project,” “intend,” “plan,” “believe,” “target,” and other words and terms of similar meaning in connection with any discussion of future operating or financial performance. There can be no assurance that management’s estimates of our future results will be achieved. Important factors that could cause actual results to differ materially from those presently expected include: adverse changes in general economic or market conditions (including market demand for electronics and downturns in the semiconductor industry); the historically cyclical nature and volatility of the markets that we serve; the “hockey-stick” pattern of sales resulting in a disproportionately large percentage of total quarterly sales occurring in the last month and weeks of each quarter; the decision by customers to cancel or defer orders that previously had been accepted; reduced bookings; reductions or delays in capital investment by our customers; competitive pressures (including pricing and gross margin pressures); the risks of operating internationally (including political and economic instability and unexpected changes in legal and regulatory requirements and in policy changes affecting international markets); disruptions, delays or shortages in an adequate supply of raw materials, components or internal and external manufacturing capability; disruptions or delays in our supply chain; incoming quality of components or raw materials; insufficient or excess inventory; the effectiveness of our implementation of cost cutting and expense control measures (including facility consolidations, the centralization of certain shared services, seeking lower prices from suppliers and the outsourcing of selected manufacturing, information technology and engineering activities); the risks of potential environmental liability; any material litigation against Teradyne; the ability to attract and retain key employees; war or the threat of terrorist attacks; and other events, factors and risks previously and from time to time disclosed in our filings with the Securities and Exchange Commission, including, but not limited to, our annual report on Form 10-K for the fiscal year ended December 31, 2005 and our periodic reports on Forms 10-Q and 8-K.

GAAP to Non-GAAP Earnings Reconciliation

References by the Company to non-GAAP income from continuing operations and non-GAAP earnings per share refer to net income or earnings per share excluding restructuring and other, net, and certain inventory provisions, as well as adjustments to profit sharing and taxes due to these exclusions. GAAP requires that these items be included in determining Net Income/(Loss) and Net Income/(Loss) per share. Non-GAAP net income from continuing operations (which is the basis for non-GAAP earnings per share) gives an indication of Teradyne's baseline performance before gains, losses or other charges that are considered by management to be outside the Company's ongoing operating results. The Company believes these non-GAAP measures will aid investors' overall understanding of the Company's results by providing a higher degree of transparency for certain expenses and credits, through providing a level of disclosure that will help investors understand how the Company plans and measures its own business. However, the presentation of non-GAAP measures is not meant to be considered in isolation or as a substitute for, or superior to, financial information provided in accordance with GAAP.
