TERADYNE ANNOUNCES FOURTH QUARTER RESULTS


     BOSTON--(BUSINESS WIRE)--Jan. 15, 2002--Teradyne, Inc. (NYSE: TER) reported
sales of $220.2 million for the fourth quarter of 2001, and a net loss of $75.6
million, or $0.42 per share, excluding special charges. Including special
charges, the net loss was $112.6 million ($0.63 per share). Gross bookings for
the quarter were $212 million, and net bookings after cancellations totaled $127
million.

     Teradyne Chairman George Chamillard stated that while Teradyne's fourth
quarter results were in line with earlier guidance, 2001 was sobering, and that
the challenges faced by Teradyne are likely to continue. He noted that "in view
of the mixed messages we are receiving from the market place, we don't see an
imminent upturn." Chamillard stated that in the face of this situation, Teradyne
anticipates that revenue for the first quarter of 2002 will be between $200
million and $250 million and losses will be in the range of $0.40 to $0.50 per
share, excluding special charges.

     "Our focus in recent months", said Chamillard, "has been on cost control,
cash management and positioning our businesses for the upturn. We will continue
to focus on those areas. We will also continue to lower our time to market and
our costs to produce the new products that we believe our customers will
demand."

     Teradyne will be conducting its conference call tomorrow, January 16, 2002,
at 8:00 a.m. EST. The call will be webcast at Teradyne's web site.

SAFE HARBOR STATEMENT

     Statements in this release, other than historical performance, include
forward-looking statements relating to future financial performance made under
the Safe Harbor provisions of the Private Securities Litigation Reform Act of
1995. These forward-looking statements include statements regarding our revenue
and profit expectations and future business strategies and market opportunities,
as well as statements regarding the possible future direction of the U.S.
economy. These statements are neither promises nor guarantees, but involve risks
and uncertainties that may cause actual results to differ materially from
expectations. In particular, our business is dependent on the current and
anticipated market demand for electronics, which has been impacted by the
economic slowdown that began in the latter portions of 2000. The uncertainty
regarding the future growth rate of worldwide economies has caused many
companies to reduce capital investment and may cause further reduction of such
investments in the future. These reductions have been particularly severe in the
electronics and semiconductor industry which Teradyne serves and have
contributed to Teradyne incurring losses in recent periods and may contribute to
further losses. In addition, the markets which Teradyne serves have historically
been quite cyclical and may continue to be so. Further, our backlog has and may
continue to be adversely affected as customers determine whether to defer or
cancel orders which previously had been accepted. All of these factors could
result in further decreased revenues. Our business is also affected by our
ability to develop and ship new and sometimes more complex products to address
changing customer needs, by new offerings by competitors and by intense
competition throughout the world in each of our operating segments from
competitors having substantial resources available for the engineering,
manufacturing, marketing and distribution of their products. The current
economic decline and the resulting oversupply could increase the possibility of
intensified price competition in certain markets and result in the need to lower
our prices, which could result in decreased revenues. In addition, our
acquisition of GenRad, Inc. during 2001 and any future acquisitions or
divestitures could affect our ability to manage and maintain our business.
Further, as a result of our issuance of $400 million aggregate principal amount
of convertible senior notes in October 2001, together with the approximately $45
million mortgage financing which we completed in December 2001, we have
substantially increased our debt service obligations and ratio of debt to total
capitalization. If our cash flow should be insufficient to meet these
obligations, we might have to reduce or curtail certain activities of our
business. Finally, our ongoing expense control measures may not have the
intended effect on our future financial results. These measures could have
long-term negative effects on our business by reducing our pool of technical
talent, decreasing improvements in our products and making it more difficult for
us to respond to large customer orders if the economy does not recover. Readers
should not place undue reliance on any such forward-looking statements, which
speak only as of the date they are made, and Teradyne undertakes no obligation
to update the information contained in this release. For further information
regarding risks and uncertainties associated with Teradyne's business, please
refer to Teradyne's filings with the Securities and Exchange Commission,
including, but not limited to, Teradyne's annual report on Form 10-K and
quarterly reports on Form 10-Q. Any forward-looking statements should be
considered in light of all these factors.
