    "I am pleased to report that earnings for the third quarter of
2007 are much better than we expected when we gave guidance to
investors in August, and that we nearly doubled the earnings reported
for the prior quarter on essentially the same revenue level," said Dr.
Robert J. Shillman, Cognex's Chairman and Chief Executive Officer.
"These positive results were due to several items in the quarter,
including a higher gross margin due to product mix, lower than planned
sales and marketing expenses and professional fees, a discrete tax
benefit, and a foreign exchange gain."

    Dr. Shillman continued, "In addition to the higher than expected
earnings we reported for the third quarter, I am also pleased to
report that some of the sales and marketing initiatives we put into
place earlier in the year are starting to gain traction. This is
likely to lead to higher revenue in the fourth quarter, both on a
sequential basis and year-on-year."

                        Details of the Quarter

    Statement of Operations Highlights - Third Quarter of 2007

    --  Revenue for the third quarter of 2007 decreased 6% from the
        third quarter of 2006 due to lower sales to the Semiconductor
        and Electronics and Surface Inspection markets, which more
        than offset an increase in sales to the Factory Automation
        market, primarily in Europe. On a sequential basis, revenue
        was flat as higher revenue from the Semiconductor and
        Electronics market and, to a lesser extent, the Factory
        Automation market, offset lower surface inspection revenue.
        The increase in Semiconductor and Electronics revenue is
        primarily due to an adjustment, which was reported by Cognex
        on August 15, 2007, that reduced second quarter revenue by
        $1,060,000 to correct for an overstatement in prior periods.

    --  Gross margin was 73% in the third quarter of 2007, 73% in the
        third quarter of 2006 and 67% in the second quarter of 2007.
        Gross margin was flat year-on-year in spite of the lower sales
        volume due to product mix. The increase in gross margin on a
        sequential basis is also due to product mix as well as a
        pre-tax charge of $2,126,000 for excess inventory in the
        second quarter that did not repeat in the third quarter.

    --  Research, Development & Engineering (R, D & E) spending in the
        third quarter of 2007 increased 9% from both the third quarter
        of 2006 and the prior quarter. The increase in R, D & E
        spending year-on-year is due to additional headcount and
        higher outside services, contract labor and patent-related
        costs, all of which are related to new product development.
        The sequential increase in R, D & E spending is due to higher
        outside services and patent-related costs in the third
        quarter, and the timing of the bonus accrual.

    --  Selling, General & Administrative (S, G & A) spending in the
        third quarter of 2007 increased 4% from the third quarter of
        2006 and decreased 1% on a sequential basis. The increase in
        S, G & A spending year-on-year is due to higher costs related
        to additional sales headcount, and the impact of foreign
        exchange rates on the company's international operations. S, G
        & A spending decreased on a sequential basis due to lower
        marketing costs, including seminars and tradeshows, which were
        partially offset by higher professional fees and the timing of
        the bonus accrual.

    --  Cognex reported a foreign currency gain of $353,000 in the
        third quarter of 2007, a loss of $282,000 in the third quarter
        of 2006 and a loss of $323,000 in the second quarter of 2007.
        The company recognizes foreign currency gains and losses on
        the revaluation and settlement of accounts receivable and
        payable balances that are reported in one currency and
        collected or paid in another.

    --  Investment and other income was $1,881,000 in the third
        quarter of 2007, $1,518,000 in the third quarter of 2006 and
        $1,938,000 in the prior quarter. Investment and other income
        increased year-on-year due to higher rental income and higher
        yields on invested balances, which were somewhat offset by a
        lower average invested balance as Cognex used cash to
        repurchase its common stock. The sequential decrease in
        investment and other income is due to a higher percentage of
        the invested balances being held in short-term accounts.

    --  The effective tax rate was 21% in the third quarter of 2007,
        18% in the third quarter of 2006 and 34% in the second quarter
        of 2007. Excluding the one-time discrete items described
        below, the tax rate would have been 26% in the second and
        third quarters of 2007, and 23% in the third quarter of 2006.
        The effective tax rate excluding discrete tax items increased
        year-on-year due to more of the company's profits being earned
        in higher tax jurisdictions than in the third quarter of 2006.

    The third quarter of 2007 includes a net tax benefit of $421,000
resulting primarily from the difference between taxes paid upon filing
the actual tax returns and the estimated expense recorded in 2006. The
second quarter of 2007 includes an unfavorable adjustment of $438,000
resulting from the filing of the actual amended tax returns arising
out of the Japanese tax audit settlement that occurred in the third
quarter of 2006. The third quarter of 2006 includes a net tax benefit
of $567,000 resulting from the unfavorable settlement of the Japanese
tax audit and the favorable impact of both the expiration of the
statute of limitations for a particular tax year and the adjustment of
estimates made based upon the filing of the actual tax returns for
2005.

    Balance Sheet Highlights - September 30, 2007

    --  Cognex's financial position at September 30, 2007 was very
        strong, with over $265,000,000, or $6.13 per outstanding
        share, in cash and investments and no debt. In the first nine
        months of 2007, Cognex generated positive cash flow from
        operations of approximately $35,000,000, paid out over
        $11,000,000 in dividends to shareholders, and spent over
        $32,600,000 to repurchase nearly 1,430,000 shares of its
        common stock on the open market.

    --  Days sales outstanding (DSO) for the third quarter of 2007 was
        64 days, and remains within the company's targeted range.

    --  Inventories at September 30, 2007, decreased by $535,000, or
        2%, from the end of 2006, and inventory turns in the third
        quarter were equivalent to 1.8 times per year. The impact of
        foreign exchange rates added approximately $1,400,000 to the
        inventory balance in the first nine months of 2007, of which
        approximately $1,000,000 was in the third quarter.

    Financial Outlook

    --  For the fourth quarter of 2007, Cognex expects revenue to be
        between $59 million and $62 million. Gross margin, including
        estimated stock option expense of $300,000, is expected to be
        in the low-to-mid-70% range. Operating expenses (R, D & E and
        S, G & A), including estimated stock option expense of
        $2,400,000, are expected to increase by between 5% and 10% on
        a sequential basis. The effective tax rate is expected to be
        26%. As a result of the above, earnings for the fourth quarter
        of 2007 are expected to be between $0.17 and $0.23 per diluted
        share.

    Non-GAAP Financial Measures

    Exhibit 2 of this press release includes a reconciliation of
certain financial measures from GAAP to non-GAAP. Cognex believes that
these non-GAAP financial measures are useful to investors because they
allow investors to more accurately assess and compare the company's
results over multiple periods and to evaluate the effectiveness of the
methodology used by management to review its operating results. In
particular, Cognex incurs expense related to stock options included in
its GAAP presentation of cost of revenue, research, development, and
engineering expenses (R,D&E), and selling, general and administrative
expenses (S,G&A). Cognex excludes these expenses for the purpose of
calculating non-GAAP adjusted gross margin, non-GAAP adjusted
operating income, non-GAAP adjusted net income and non-GAAP adjusted
earnings per share when it evaluates its continuing operational
performance and in connection with its budgeting process and the
allocation of resources, because these expenses have no current effect
on cash or the future uses of cash and they fluctuate as a result of
changes in Cognex's stock price. Cognex also excludes certain items if
they are one-time discrete events, such as those affecting cost of
revenue and the tax provision. Cognex does not intend for these
non-GAAP financial measures to be considered in isolation, nor as a
substitute for financial information provided in accordance with GAAP.
