share, compared to a net loss of $6,451,000, or $0.15 per diluted

    "I am happy to report that in the third quarter, both revenue and
profits increased year-on-year and sequentially," said Dr. Robert J.
Shillman, Cognex's Chief Executive Officer and Chairman. "This is the
second quarter in a row that we reported favorable comparisons, and we
currently expect this positive trend to continue for our results in
Q4-03 as well. Although spending on capital equipment by manufacturing
companies remains tight, business continues to improve each quarter.
Irrespective of the pace of recovery, we intend to continue to use our
exceptionally strong balance sheet to pursue growth opportunities,
including acquisitions."

    Details of the Quarter

    Statement of Operations Highlights - Third Quarter of 2003

    --  Revenue for the third quarter of 2003 increased 22% over the
        comparable quarter in 2002 and 6% on a sequential basis. The
        year-on-year increase is due to higher sales to Original
        Equipment Manufacturer (OEM) customers in the semiconductor
        and electronics industries as well as to end-user customers
        across a variety of industries. The sequential increase is
        primarily due to higher sales to OEM customers in the
        semiconductor industry.

    --  Gross margin was 66% in the third quarter of 2003 compared to
        65% in the comparable quarter in 2002 and 67% in the prior
        quarter. Cost of revenue for the second and third quarters of
        2003 as well as the third quarter of 2002 includes a benefit
        of $569,000, $296,000 and $1,156,000, respectively, relating
        to an inventory reserve recorded in the fourth quarter of
        2001. Excluding this benefit, gross margin would have been 65%
        in the third quarter of 2003, 62% in the third quarter in
        2002, and 66% in the prior quarter. The increase in gross
        margin year-on-year is primarily due to the higher sales
        volume. The decline in gross margin on a sequential basis is
        due to pricing discounts given to certain customers as well as
        lower service revenue resulting from the timing of educational
        classes and consulting projects.

    --  Research, Development & Engineering (R, D & E) spending in the
        third quarter of 2003 decreased 7% from the comparable quarter
        in 2002. This decrease is primarily due to cost-cutting
        measures implemented by the company, including the workforce
        reduction announced by Cognex on August 1, 2002. R, D & E
        spending was essentially flat on a sequential basis.

    --  Selling, General & Administrative (S, G & A) spending in the
        third quarter of 2003 decreased 12% from the comparable
        quarter in 2002 primarily due to the company's cost-cutting
        measures. On a sequential basis, S, G & A spending was
        essentially flat with the prior quarter.

    --  Investment and other income was $1,145,000 in the third
        quarter of 2003 compared to $2,626,000 in the comparable
        quarter of 2002 and $1,615,000 in the prior quarter. The
        decrease year-on-year is primarily due to lower yields on
        investments. On a sequential basis, the decrease in investment
        and other income is due to losses realized in the third
        quarter as compared to gains in the second quarter.

    --  The foreign currency gain was $828,000 in the third quarter of
        2003 as compared to a gain of $109,000 in the comparable
        quarter of 2002 and a loss of $1,164,000 in the prior quarter.
        The company recognizes foreign currency gains and losses on
        the collection and translation of accounts receivable balances
        that are reported in one currency and collected in another.

    Balance Sheet Highlights - September 28, 2003

    --  Cognex's financial position remains very strong at September
        28, 2003, with nearly $300,000,000 in cash and investments and
        no debt. Cash and investments increased over $22,000,000 from
        the end of 2002. This increase is the net result of positive
        cash flow from operations and cash received from the exercise
        of employee stock options, less the payment of approximately
        $7,600,000 in the second quarter to acquire the Siemens
        Dematic AG's wafer identification business as well as the
        payment of approximately $2,600,000 in the third quarter for
        the company's first-ever dividend.

    --  Days sales outstanding (DSO) for the third quarter of 2003 was
        66 days, compared to 62 days in the prior quarter. DSO remains
        within the company's targeted range.

    --  Inventories at September 28, 2003 decreased 20% from the end
        of 2002, as inventory turns improved in the third quarter to a
        rate equivalent to 3.4 times per year from 2.4 times per year
        in the fourth quarter of 2002.

    Business Trends and Financial Outlook

    --  In the third quarter of 2003, bookings declined 4% on a
        sequential basis and the company's book-to-bill ratio was
        slightly below 1.0. This decrease was primarily due to the
        timing of orders received by the company's Surface Inspection
        Systems Division, which had record bookings in the first half
        of 2003. Cognex expects revenue for the fourth quarter of 2003
        to be between $39 million and $42 million. At that revenue
        level, gross margin is expected to be in the mid-60% range.
        Operating expenses (R, D & E and S, G & A) for the fourth
        quarter are expected to remain essentially flat on a
        sequential basis. The effective tax rate for the fourth
        quarter of 2003 is expected to be 31%. And, as a result of the
        above, earnings for the fourth quarter are expected to be
        between $0.11 and $0.14 per diluted share, excluding any
        benefit from the sale of previously reserved inventory.
