Exhibit 99.1

Cognex Reports Third Quarter Results

NATICK, Mass.--(BUSINESS WIRE)--October 29, 2012--Cognex Corporation (NASDAQ: CGNX) today announced its financial results for the third quarter of 2012. Selected financial data for the quarter and nine months ended September 30, 2012, are compared to the second quarter of 2012, the third quarter of 2011 and the first nine months of 2011 in Table 1 below.

A reconciliation of certain financial measures from GAAP to non-GAAP is shown in Exhibit 2.

“In view of the pull back in spending by manufacturers, we are quite pleased that third quarter revenue was in line with our expectations and that we reported a high level of profitability (operating margin was 27% and net margin was 22%),” said Dr. Robert J. Shillman, Chairman of Cognex. “While these results were good, it is frustrating to see our momentum dampened by the slowing global economy.”

“We performed well during what is typically a seasonally soft quarter for Cognex,” said Robert J. Willett, Chief Executive Officer of Cognex. “Despite total revenue being flat year-on-year, factory automation revenue grew 4% over the third quarter of 2011 (9% in constant currency), helped by our continued strong performance in ID products and in China.”

Details of the Quarter

Statement of Operations Highlights – Third Quarter of 2012

• Revenue for the third quarter of 2012 was flat with the third quarter of 2011 and decreased 5% from the prior quarter. Factory automation, the company’s largest market segment, performed better than expected in what is typically a seasonally soft quarter, increasing 4% year-on-year and remaining flat on a sequential basis. Growth year-on-year in factory automation was offset by lower revenue from the semiconductor and electronics capital equipment market (SEMI). Revenue declined on a sequential basis primarily due to lower SEMI revenue. Surface inspection revenue, which is impacted by the timing of deliveries, installations and revenue deferrals, decreased 1% year-on-year and 8% on a sequential basis.
• Gross margin was 76% in all periods presented.
• Research, Development & Engineering (RD&E) spending in the third quarter of 2012 decreased 6% from the third quarter of 2011 and 3% from the prior quarter. The company’s investment in engineering personnel hired to accelerate new product introductions was more than offset by a lower bonus accrual and the impact of currency exchange rates on the company’s international operations. RD&E decreased on a sequential basis due to higher employee vacation time and the timing of outside services for products under development.

• Selling, General & Administrative (SG&A) spending in the third quarter of 2012 increased 2% from the third quarter of 2011 and decreased 5% from the prior quarter. SG&A increased year-on-year due to sales force expansion offset by a lower bonus accrual and the impact of currency exchange rates. The sequential decrease is due to the timing of marketing initiatives, lower stock option expense and higher employee vacation time.
• Investment and other income was $692,000 in the third quarter of 2012, $761,000 in the third quarter of 2011 and $1,702,000 in the prior quarter. The decrease year-on-year is due to lower yields on investments offset by a higher average invested balance. The sequential decrease is due to gains of approximately $1,000,000 recognized in the prior quarter on the sale of euro-denominated investments.
• The tax rate was 19% in the third quarter of 2012 compared to 21% in both the third quarter of 2011 and the prior quarter. Excluding tax adjustments, the tax rate was 21% in the third quarter of 2012 and 23% in the third quarter of 2011. The decrease year-on-year is primarily because a higher percentage of income in the third quarter of 2012 was earned in lower tax jurisdictions.

Balance Sheet Highlights – September 30, 2012

• Cognex’s financial position as of September 30, 2012, was very strong, with no debt and $415,938,000 in cash and investments. Cognex paid out $4,721,000 in dividends to shareholders in the third quarter of 2012.

Financial Outlook

• Cognex expects revenue for Q4-12 to be between $78 million and $81 million. Gross margin is expected to continue in the mid-70% range. Operating expenses are expected to increase by up to 5% on a sequential basis, primarily as a result of lower employee vacation time. And the effective tax rate is expected to be 21% before discrete tax items.

Non-GAAP Financial Measures

• Exhibit 2 of this press release includes a reconciliation of certain financial measures from GAAP to non-GAAP. Cognex believes these non-GAAP financial measures are useful because they allow investors to more accurately assess and compare Cognex 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 the impact of 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.
