“The fourth quarter of 2007 was a very good quarter for Cognex,” said Dr. Robert J. Shillman, the Chairman and Chief Executive Officer of Cognex. “I am pleased to say that revenue and earnings per share, excluding stock option expense, were at the highest level since the Internet bubble burst seven years ago. In addition, we set two new records for quarterly revenue; first in the Surface Inspection market, where we had revenue of $12 million in the fourth quarter, and second in the Factory Automation market, where revenue was $40 million and now represents our largest market.”

Dr. Shillman continued, “I am feeling more optimistic about our future today than I was at this point last year. We spent a great deal of time, effort and money in 2007 working on product development and realigning our sales force. As a result of both of those efforts, we expect to introduce a number of important new products in 2008, and our direct sales team and network of distributors are starting 2008 energized and focused on selling. It appears that 2008 will be a great year for Cognex.”

Details of the Quarter

Statement of Operations Highlights – Fourth Quarter of 2007

• Revenue for the fourth quarter of 2007 increased 12% from the fourth quarter of 2006, and 19% from the prior quarter due to higher sales to the Factory Automation and Surface Inspection markets, both of which set new records for quarterly revenue. Notably, the increase in Factory Automation revenue, both year-on-year and sequentially, was across a number of different industries with the largest increase in absolute dollars from Europe. The increase in Factory Automation and Surface Inspection was offset somewhat by a decline in the Semiconductor and Electronics Capital Equipment Market, which has been in a cyclical slowdown since early 2006.
• Gross margin was 73% in the fourth quarter of 2007, 72% in the fourth quarter of 2006 and 73% in the prior quarter. The increase in gross margin year-on-year is primarily due to the higher sales volume in the fourth quarter of 2007. Gross margin was flat on a sequential basis despite higher revenue due to product mix; a greater percentage of revenue in the fourth quarter of 2007 as compared to the third quarter came from the sale of surface inspection systems than from modular vision systems.

• Research, Development & Engineering (R, D & E) spending in the fourth quarter of 2007 increased 19% from the fourth quarter of 2006 and 11% from the prior quarter. The increase in R, D & E spending year-on-year is due to higher employee-related costs, contract labor and patent-related costs. The sequential increase is due to higher patent-related costs and stock option expense.
• Selling, General & Administrative (S, G & A) spending in the fourth quarter of 2007 increased 11% from both the fourth quarter of 2006 and the prior quarter. The increase in S, G & A spending, both year-on-year and sequentially, is due to higher costs related to additional sales headcount, professional fees, and the impact of foreign exchange rates on the company’s international operations. Higher stock option and marketing expenses also contributed to the increase on a sequential basis.
• Cognex reported foreign currency gains of $367,000 in the fourth quarter of 2007, $374,000 in the fourth quarter of 2006 and $353,000 in the prior quarter. 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 $2,110,000 in the fourth quarter of 2007, $1,581,000 in the fourth quarter of 2006 and $1,881,000 in the prior quarter. The increase, both year-on-year and sequentially, is due to higher yields on invested balances. Higher rental income in 2007 also contributed to the increase over the fourth quarter of 2006.
• The effective tax rate was 19% in the fourth quarter of 2007, 19% in the fourth quarter of 2006 and 21% in the third quarter of 2007. Excluding the items described below, the tax rate would have been 19% in the fourth quarter of 2007, 25% in the fourth quarter of 2006 and 26% in the prior quarter. The decrease, both year-on-year and sequentially, is primarily due to more of the company’s profits being earned in lower tax jurisdictions.

-- The fourth quarter of 2007 includes a benefit of approximately $1,500,000 resulting from a reduction in the effective tax rate for 2007 as more of the company's profits were earned in lower tax jurisdiction than expected. It also includes unfavorable adjustments of $1,350,000 for possible tax exposures recognized under FIN 48, and $191,000 for capital loss carry forwards that are not expected to be utilized.

-- The fourth quarter of 2006 includes favorable adjustments of approximately $700,000 due to adjusting an estimate of a tax audit settlement upon filing the actual tax return, and the retroactive reinstatement of the Research & Development tax credit.

-- 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 for 2006 and the estimated expense recorded for that year.

Balance Sheet Highlights – December 31, 2007

• Cognex’s financial position at December 31, 2007 was very strong, with approximately $268,000,000 in cash and investments and no debt. In 2007, Cognex generated positive cash flow from operations of more than $48,000,000, paid out approximately $15,000,000 in dividends to shareholders, and spent more than $32,000,000 to repurchase approximately 1,430,000 shares of its common stock on the open market.
• Days sales outstanding (DSO) for the fourth quarter of 2007 was 52 days, and remains within the company’s targeted range.
• Inventories at December 31, 2007, decreased by approximately $3,100,000, or 10%, from the end of 2006, and inventory turns in the fourth quarter were equivalent to 2.4 times per year. The impact of foreign exchange rates added approximately $2,000,000 to the inventory balance in 2007; excluding this impact, inventories would have decreased by more than $5,100,000, or 17%.

Financial Outlook

For the first quarter of 2008, Cognex expects revenue to be between $58 million and $61 million. Although this range is lower than the revenue reported for the fourth quarter of 2007, it represents a significant increase as compared to the first quarter of 2007. Gross margin is expected to be in the low-70% range. Operating expenses (R, D & E and S, G & A) are expected to be essentially flat on a sequential basis. The effective tax rate is expected to be 23%. As a result of the above, earnings for the first quarter of 2008 are expected to be between $0.13 and $0.18 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 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.
