EXHIBIT 99.1 Cognex Corporation Announces Delay in Second Quarter Earnings Release Date and Conference Call NATICK, Mass.--(BUSINESS WIRE)--July 25, 2007--Cognex Corporation (NASDAQ: CGNX) announced today that its earnings release for the second quarter of 2007 has been delayed due to a voluntary internal review of irregularities that it discovered in certain transactions originating at its Japanese subsidiary. Immediately upon this discovery, the company reported this matter to Cognex's Audit Committee, which then instructed the company to hold an internal review and to report its findings to them. The Audit Committee also appointed outside counsel (who then engaged forensic accounting professionals), and it directed them to conduct a full, thorough and independent investigation of the problem and to report its findings to the Audit Committee. The independent counsel has not yet completed its investigation, but to the company's knowledge, it has not uncovered any financial irregularities other than those discovered by the company's internal review, which are listed below: -- In the fourth quarter of 2006, there were improper orders which generated approximately $757,000 in revenue, $644,000 in operating income, and $483,000 in net income (or $0.01 per diluted share). -- In the first quarter of 2007, there were improper orders which generated approximately $303,000 in revenue, $262,000 in operating income, and $194,000 in net income (with no change in net income per diluted share). In addition, and as a result of its internal review, Cognex has reversed the $400,000 order for DataMan(TM) handheld ID readers that the company announced on June 14, 2007. The company, its Audit Committee, its current auditors and the independent counsel are all working diligently to resolve this matter. Cognex does not intend to issue any other public statements regarding this matter until the independent counsel completes its investigation.
