EXHIBIT 99.1 FOR IMMEDIATE RELEASE Contact: Bruce Wright (investment community) (408) 571-3000 x7050 Roberta Emerson (media) (408) 571-3000 x7037 TENCOR INSTRUMENTS REPORTS FIRST QUARTER OPERATING RESULTS Milpitas, Calif. -- April 23, 1997 -- Tencor Instruments (Nasdaq:TNCR) today announced operating results for the first quarter ended March 31, 1997. Net income for the quarter was $13.3 million compared with $20.3 million a year ago. Revenues were $94.6 million compared with $106.3 million for the first quarter last year, which was during the peak of the semiconductor equipment industry cycle. Earnings per share were 41 cents, compared with 64 cents in the same quarter last year. However, net income increased 3.1 percent and revenues rose 4.5 percent from the quarter ended December 31, 1996. "During the first quarter, we continued to see an improvement in bookings, rising from the low point we saw in the third quarter of last year," noted Jon D. Tompkins, chairman, president and chief executive officer. "Bookings increased 46 percent to $107 million from the prior quarter, due in part to record orders for the Surfscan AIT and Surfscan SP1, our flagship wafer inspection systems. This increase in bookings raised book-to-bill for the quarter to 1.14-to-1 and grew backlog to $145 million." "In January we added to our line of products for the data storage industry, introducing the Tencor HRP-100, a high resolution surface profiler which was specifically designed for use in the manufacture of disk drives and thin film heads," said Tompkins. Revenues from outside the United States represented 63 percent of total revenues during the March 1997 quarter, comparable with the 64 percent reached in the March quarter one year ago. _____________________________________________________________________________ |Except for statements of historical fact, the statements in this press | |release are forward-looking statements.
