Details of the Quarter

Statement of Operations Highlights – First Quarter of 2013

• Revenue increased 4% from Q1 2012 and decreased 2% from Q4 2012. On a year-on-year basis, growth came from the factory automation market where revenue increased 7% to set a new quarterly revenue record of $63 million. On a sequential basis, revenue decreased as expected due to lower surface inspection revenue as compared to the near-record level reported for Q4 2012. Somewhat offsetting the decline in surface inspection revenue was higher SEMI revenue. In addition, factory automation revenue also increased, which is contrary to the typical Q4 to Q1 trend.
• Gross margin was 76% in Q1 2013 as compared to 75% reported for both Q1 and Q4 of 2012.
• Research, Development & Engineering (RD&E) spending increased 9% from Q1 2012 and 4% from Q4 2012. The increase, both year-on-year and sequentially, was due to the company’s investment in engineering personnel hired to accelerate the introduction of new products. In addition, the year-on-year increase includes higher spending on outside services for products under development. The sequential increase also includes higher stock option expense.

• Selling, General & Administrative (SG&A) spending increased 5% from Q1 2012 and 6% from Q4 2012. The increase year-on-year is due to Cognex’s sales force expansion, primarily in China. The sequential increase is due to higher personnel-related costs, particularly stock option expense, and demonstration equipment related to new product introductions.
• The tax rate was 16% in Q1 2013 compared to 21% in Q1 2012 and 24% in Q4 2012. Excluding discrete tax items, the tax rate was 19%, 21% and 21%, respectively (tax adjustments are summarized in Exhibit 2). The tax rate excluding tax adjustments decreased both year-on-year and sequentially due to a higher percentage of income being earned in lower-tax jurisdictions.

Balance Sheet Highlights – March 31, 2013

• Cognex’s financial position as of March 31, 2013, was very strong, with no debt and $413,652,000 in cash and investments.

Financial Outlook

• Cognex expects revenue for Q2 2013 to be between $83 million and $86 million. Gross margin is expected to continue in the mid-70% range. Operating expenses are expected to increase by approximately 3% on a sequential basis. The effective tax rate is expected to be 19%.

Non-GAAP Financial Measures

• Exhibit 2 of this news release includes a reconciliation of certain financial measures from GAAP to non-GAAP. Cognex believes these non-GAAP financial measures are helpful because they allow investors to more accurately compare Cognex results over multiple periods using the same methodology used by management in its budgeting process and in its review of Cognex’s operating results. In particular, non-GAAP presentations exclude the following: (1) stock option expense for the purpose of calculating non-GAAP adjusted operating income, non-GAAP adjusted net income and non-GAAP adjusted net income per share (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), (2) the impact of currency exchange rate fluctuations from non-GAAP revenue (because period-to-period comparisons are better understood by assuming constant exchange rates), and (3) certain one-time discrete events, such as tax adjustments. Cognex does not intend for 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. However, if a specific tax rate or tax treatment is required because of the nature of the item and/or the tax jurisdiction where the item was recorded, the tax effect is estimated by applying the relevant specific tax rate or tax treatment rather than the effective tax rate.
