  ESI Announces Fiscal 2003 Third and Fourth Quarters and Full Year
         Results and Previous Periods Financial Restatements

    PORTLAND, Ore.--(BUSINESS WIRE)--Aug. 11, 2003--Electro Scientific
Industries, Inc. (Nasdaq:ESIOE) announced financial results for the
fiscal 2002 financial restatement, first and second quarter of fiscal
2003 financial restatement, third and fourth quarters of fiscal 2003
and fiscal year ended May 31, 2003. The company previously announced
the restated results on July 15, 2003. Updated financial results are
attached in a tabular format.
    Fourth quarter 2003 sales were $22.5 million, compared with last
year's fourth quarter sales of $40.4 million. Sales for the full year
were $136.9 million, compared with $162.9 million in fiscal 2002. The
net loss for the fourth quarter was $20.8 million, or $0.75 per
diluted share, compared with net loss of $8.5 million, or $0.31 per
diluted share, in the fourth quarter of fiscal 2002. The net loss for
the full year was $50.1 million, or $1.81 per diluted share, compared
with a net loss in fiscal 2002 of $17.8 million, or $0.65 per diluted
share. In the fourth quarter of 2003, the company recorded an
impairment charge in the value of certain long-term fixed assets for a
total of $10.1 million. This impairment charge was primarily related
to the Klamath Falls consumables manufacturing site.
    "Our year was very difficult, both in our external markets and in
our internal affairs," said Barry Harmon, president and chief
executive officer of ESI. "Now that we have completed the Audit
Committee investigation and reported our fiscal 2003 audited financial
results, the management team is focusing its attention on strategic
customer initiatives, operating plans and core business processes.
This work will clearly require an enormous effort as ESI recovers from
the impact of the accounting restatements and a prolonged trough in
the business cycle. That being said, we believe that the tone of our
business is improving during the first quarter of fiscal 2004. All
product groups are experiencing increased orders and the number of
active sales discussions are increasing, indicating that customer
capacity additions should occur at a faster rate than fiscal 2003."
    Cash and investments as of May 31, 2003, were $308 million, up $6
million over the prior year.
    Net orders for the latest quarter were $25.5 million, a decrease
of 18.2% compared with $31.2 million in the third quarter and a
decrease of 43.4% compared with $45.1 million in the fourth quarter of
fiscal 2002. Backlog was $11 million at May 31, 2003, as compared to
$22.6 million at June 1, 2002. The deferred revenue balance at May 31,
2003, was $13.2 million as compared to $5.3 million at June 1, 2002.
    In conjunction with the filing of a current report on Form 8-K,
which includes this press release, ESI also filed with the Securities
and Exchange Commission a Form 10-K/A for fiscal 2002; amendments to
its quarterly reports on Form 10-Q/A for the first and second quarters
of fiscal 2003; and its quarterly report on Form 10-Q for the third
quarter of fiscal 2003.

as defined within the Private Securities Litigation Reform Act of
1995. These statements include the prospect of customer capacity
additions in fiscal 2004. These statements are subject to risks and
uncertainties that could cause actual results to differ materially
