                 ESI Announces Second Quarter Results,
          Reports Strongest Shipments and Revenue Since 2001


    PORTLAND, Ore.--(BUSINESS WIRE)--Oct. 24, 2007--Electro Scientific
Industries, Inc. (NASDAQ:ESIO), a leading provider of world-class
photonic and laser micro-engineering systems, today announced results
for its fiscal 2008 second quarter, representing the three-month
period of July 1, 2007 through September 29, 2007. Due to the change
in the fiscal year, comparisons are made to the fourth quarter of
fiscal 2007, which was the last full three-month fiscal period for the
company. All results include the impact of the acquisition of New Wave
Research, Inc. (NWR) on July 20, 2007.

    Q2 2008 to Q4 2007 Comparisons

    Second quarter sales were $82.3 million, representing a 15%
increase from the fourth quarter and the highest quarterly revenue
level since fiscal 2001. Operating income for the quarter was $7.5
million, including the impact of $4.3 million of purchase accounting
adjustments related to the purchase of NWR. Excluding the impact of
purchase accounting adjustments, operating income was $11.8 million,
compared to $10.5 million for the fourth quarter of fiscal 2007.
Second quarter net income was $5.5 million, or $0.19 per diluted
share. Without the impact of purchase accounting, net income was $9.8
million, or $0.34 per diluted share, compared with net income of $7.9
million, or $0.27 per diluted share, in the fourth quarter.

    Second quarter orders were $74.4 million, up 3% compared with
$72.3 million in the fourth quarter of 2007. Orders exceeded $70
million for the third consecutive quarter and represented the highest
amount booked since the fourth quarter of 2004. Orders for the second
quarter reflected an increase from the fourth quarter in the passive
component and interconnect market segments. Semiconductor orders were
down from the fourth quarter due to the timing of customer purchases
in June.

    "The second quarter of 2008 represented another successful period
for ESI," noted Nick Konidaris, ESI president and CEO. "In addition to
achieving the highest quarterly shipment and revenue results since
2001, we recorded the highest order level since the fourth quarter of
2004. Our interconnect segment reported the second consecutive record
breaking quarter for orders and the passive component group achieved
the highest order levels since 2001. In our semiconductor segment, we
received multiple orders for our newest memory repair system, the 9850
UV. In late July, we concluded the purchase of NWR and the partial
quarter results from this acquisition contributed to the strong
success of the quarter."

    Gross margin for the second quarter was 45%, including the impact
of $1.1 million in purchase accounting charges to cost of goods sold.
Excluding the impact of purchase accounting, gross margin for the
second quarter was 46%, consistent with the fourth quarter of fiscal
2007.

    Operating expenses were $29.3 million including the impact of $3.2
million in purchase accounting charges. Approximately $2.8 million of
the purchase accounting charges consisted of the write-off of
in-process research and development. Excluding the impact of purchase
accounting, operating expenses for the quarter were $26.1 million,
compared to $22.8 million in the fourth quarter of fiscal 2007. The
increase in expense levels compared to the fourth quarter was due to
the addition of NWR.

    Second quarter interest and other income of $2.1 million was down
compared to the fourth quarter. The decline was primarily due to lower
average cash balances resulting from the purchase of NWR and the
impact of our stock repurchase program.

    Income tax expense for the second quarter was $4.1 million, an
effective tax rate of 42%. The increase in tax rate over fiscal 2007
was due to the impact of non-deductible purchase accounting charges.

    YTD Results

    Year to date results, which represent the period June 3, 2007 to
September 29, 2007, were as follows: orders totaled $99 million;
shipments were $104 million; and revenue was $99 million. Net income,
including purchase accounting adjustments, was approximately $7
million, or $0.24 per diluted share. These results include NWR
activity from the date of acquisition on July 20, 2007 through
September 29, 2007 as follows: orders of $6 million; shipments of $6
million; and revenue of $5 million.

    Financial Position Overview

    Cash and investments were $179 million, down $49 million from the
fourth quarter of fiscal 2007. The decrease was primarily the result
of the $36 million net cash investment for the acquisition of NWR and
$25 million in stock repurchases for the four month period. Cash
generated from operations was $8 million for the second quarter and
$12 million year-to-date.

    Accounts receivable were $56 million, including $5 million from
NWR, down slightly compared to the end of the fourth quarter.

    Inventories of $92 million increased $11 million from the fourth
quarter. Approximately half of the increase was due to the acquisition
of NWR inventory. The remaining increases were primarily due to the
ramp in activity surrounding demand for passive component and
interconnect products.

    Deferred revenue increased from the fourth quarter to $19 million
due to customer-specific acceptance criteria on orders that shipped
late in the quarter.

    Konidaris added, "For the third quarter, we expect shipments and
revenue to be approximately $73 to $83 million. The gross margin
percentage is expected to be approximately 44 percent due to changes
in product mix in the third quarter and the impact of purchase
accounting adjustments. Purchase accounting amortization is expected
to impact third quarter margins by $500 thousand. Excluding the impact
of purchase accounting, margins are estimated at approximately 45
percent. Operating expenses are expected to range from $26 to $28
million for the quarter, including $1 million of integration costs and
$500 thousand in purchase accounting amortization. We estimate net
interest and other income will be approximately $1.7 million. The
effective tax rate is anticipated to be approximately 37%, or 32%
excluding the impact of purchase accounting.

    "Although our business is cyclical in nature, our long-term focus
and investment in the development of new products and applications has
resulted in a more diversified business structure for ESI. We expect
demand for our new products in the semiconductor segment, particularly
from our dual beam IR and UV tools, will remain healthy in the
near-term. We expect demand for products in both our passive component
and interconnect & micro-machining groups to remain strong. In
addition, new product offerings from our New Wave division are
expected to further expand our growth potential going forward."

    The company will hold a conference call today at 5:00 p.m. Eastern
Time. The session will include a review of the financial results,
operational performance, business outlook, and a question and answer
