Exhibit 99.1

Cognex Reports Record Results for Fiscal Year 2011

NATICK, Mass.--(BUSINESS WIRE)--February 9, 2012--Cognex Corporation (NASDAQ: CGNX) today announced that the company set new records in 2011 for annual revenue, net income and net income per share. Selected financial data for the quarter and year ended December 31, 2011 are compared to the fourth quarter of 2010, the third quarter of 2011, and the year ended December 31, 2010 in Table 1 below.

• In looking at the year-on-year comparisons, it should be noted that the quarter and year ended December 31, 2010 included $6.5 million of service revenue from a single factory automation customer contract that had been deferred for several years until the contract was completed. Excluding that contract, revenue for the quarter and year ended December 31, 2011 increased year-on-year by 7% and 13%, respectively. A reconciliation of revenue from GAAP to non-GAAP is shown in Exhibit 2.

“Cognex had another outstanding year in 2011,” said Dr. Robert J. Shillman, Chairman of Cognex. “We set new records for annual revenue, net income and earnings per share. Growth was driven by sales of our machine vision products in both the factory automation and surface inspection markets; in fact, we set new records for annual revenue in each of those markets. And we were highly profitable in 2011, reporting operating margins of 27% and net margins of 22%, even with the significant investments we made in new product development and expansion of our sales team.”

“We ended 2011 on a very good note,” said Robert J. Willett, Chief Executive Officer of Cognex. “Our continued strong execution in factory automation resulted in record quarterly revenue from that market in the fourth quarter. Growth was strongest in the Americas, in particular from automotive and ID products customers, and in China. We also set a new quarterly revenue record in the surface inspection market, substantially exceeding the prior record. Much of that growth came from the paper industry.”

“We believe that Cognex is well positioned as we enter 2012 to deliver on our strategic initiatives,” continued Mr. Willett. “However, that fact may not be obvious in our first quarter revenue outlook for 2012. We’ve detailed the primary reasons why in the Financial Outlook section of this press release.”

Details of the Quarter

Statement of Operations Highlights – Fourth Quarter of 2011

• Revenue for the fourth quarter of 2011 decreased 1% from the fourth quarter of 2010. However, revenue increased 7% year-on-year excluding the $6.5 million service revenue in Q4-10 mentioned above. Revenue for the fourth quarter of 2011 increased 5% from the prior quarter. Revenue growth, both year-on-year and sequentially, came from the factory automation and surface inspection markets, both of which set new quarterly revenue records. Growth in factory automation and surface inspection was partially offset by lower revenue from the semiconductor and electronics market (SEMI).
• Gross margin was 75% in the fourth quarter of 2011, 72% in the fourth quarter of 2010, and 76% in the prior quarter. Gross margin increased year-on-year due to improved product margins, and product sales representing a greater percentage of revenue. Gross margin decreased on a sequential basis due to surface inspection systems representing a greater percentage of company revenue.

• Research, development and engineering (RD&E) spending in the fourth quarter of 2011 increased 16% from the fourth quarter of 2010, and decreased 2% from the prior quarter. The increase year-on-year is due to investments in engineering personnel and materials to accelerate new product introductions.
• Selling, general and administrative (SG&A) spending in the fourth quarter of 2011 increased 7% from the fourth quarter of 2010, and 10% from the prior quarter. The increase year-on-year is due to sales force expansion and higher stock option expense. The increase on a sequential basis is also due to sales force expansion and stock option expense as well as higher commissions and the timing of year-end audit fees.
• The tax rate was 12% in the fourth quarter of 2011, compared to 14% in the fourth quarter of 2010 and 21% in the prior quarter. Excluding various tax adjustments, the tax rate was 20% in the current fourth quarter and in the fourth quarter of 2010, and 23% in the prior quarter. A reconciliation of the tax rate from GAAP to non-GAAP is shown in Exhibit 2.

Balance Sheet Highlights – December 31, 2011

• Cognex’s financial position as of December 31, 2011 was very strong, with no debt and $357,440,000 in cash and investments. In the fourth quarter of 2011, Cognex paid out $4,217,000 in dividends to shareholders.
• Inventories as of December 31, 2011 increased by $5,381,000, or 24%, from the end of 2010 in support of the higher level of business in 2011. Also contributing to the increase were strategic purchases and preparation for planned new product introductions.

Financial Outlook

• For Q1-12, Cognex expects revenue to be between $74 million and $77 million, gross margin to be at approximately the same level as reported for Q4-11, and operating expenses to be essentially flat on a sequential basis. The effective tax rate is expected to be 21%.
• Revenue for Q1-12 is expected to be essentially flat to up 4% from Q1-11 due to growth in factory automation and surface inspection. This is expected to be offset by significantly lower revenue from the semiconductor, electronics and solar industries due to a continued market downturn. Cognex also anticipates a negative impact from foreign exchange rates.
• Looking at Q1-12 on a sequential basis, revenue is expected to decrease by 8% to 12% from Q4-11. Cognex expects factory automation revenue to decline as it typically does from Q4 to Q1, surface inspection revenue to be lower than the record level in Q4-11, and a continued decline in SEMI.

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 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, the GAAP presentation of cost of revenue, RD&E and SG&A expenditures includes stock option expense. Cognex excludes these expenses for the purpose of calculating non-GAAP adjusted operating income, non-GAAP adjusted net income and non-GAAP adjusted net income 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 revenue from certain customers and tax adjustments. 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.

• The tax effect of items identified in the reconciliation is estimated by applying the effective tax rate to the pre-tax amount, unless the nature of the item and/or the tax jurisdiction in which the item has been recorded requires application of a specific tax rate or tax treatment. In that case, the tax effect of such items is estimated by applying such specific tax rate or tax treatment.
