            NEXTEST ANNOUNCES SECOND QUARTER FISCAL YEAR 2007 RESULTS

    SAN JOSE, Calif., Feb. 1 /PRNewswire-FirstCall/ -- Nextest Systems
Corporation (Nasdaq: NEXT), a leader in the manufacture of automatic test
equipment (ATE) for low-cost semiconductor manufacturing, today reported
financial results for its fiscal second quarter ended December 23, 2006.

    Revenue for the quarter ended December 23, 2006 was $17,930,000, down 33
percent from the September 2006 quarter revenue of $26,859,000 and down 8
percent from the December 2005 quarter revenue of $19,425,000. Net income for
the quarter was $2,215,000, compared with net income of $4,784,000 in the
previous quarter and net income of $1,682,000 in the December 2005 quarter.

    Net income available to common stockholders for the quarter ended December
23, 2006 was $2,215,000, or $0.12 per diluted share, compared with net income
available to common stockholders of $4,784,000, or $0.25 per diluted share in
the September 2006 quarter and net loss available to common stockholders of
$95,000, or $0.01 per diluted share in the December 2005 quarter. The December
2005 quarter included accretion of the then-outstanding Series B preferred stock
in the amount of $1,777,000.

    New orders for the quarter ended December 23, 2006 were $25.5 million.
Backlog at the end of the quarter was $16.7 million.

    Nextest has signed a 10-year lease on a new 128,000 sq ft building in San
Jose for a period that ends on December 31, 2016.

    Robin Adler, chairman and CEO of Nextest, commented, "Despite the soft
business conditions in the semiconductor market, our bookings were $25.5
million, which represents a positive book-to-bill ratio. In the flash memory
sector, while bit output continued to grow, severe price declines forced flash
manufacturers to extract additional productivity from existing installed bases
of test equipment, slowing investment in additional test capacity. Sharply
declining prices, however, increase demand for flash memory. We are encouraged
by our growth prospects in flash and in the other markets that we address."

    Third Quarter Fiscal 2007 Outlook

    Net revenue in the third quarter of fiscal 2007 is expected to be between
$18 million and $22 million, with earnings per diluted share of between $ 0.03
and $0.10. The fully diluted share count is estimated to be approximately 19
million at the end of the third quarter.
