NATICK, Mass.--(BUSINESS WIRE)--July 31, 2017--Cognex Corporation (NASDAQ: CGNX) today announced its financial results for the second quarter of 2017 (ended July 2, 2017). Table 1 below shows selected financial data for Q2-17 compared to Q2-16, Q1-17 and the first six months of 2017 compared to the first six months of 2016. A reconciliation of certain financial measures from GAAP to non-GAAP is shown in Exhibit 2 of this news release.

*Table 1 excludes the results of discontinued operations, which relate to the company’s Surface Inspection Systems Division (SISD) that was sold on July 6, 2015.

Details of the Quarter

Statement of Operations Highlights – Second Quarter of 2017

• Revenue for Q2-17 grew 17% from Q2-16 and 28% from Q1-17. Growth year-on-year across a number of industries was partially offset by lower revenue from the consumer electronics industry. On a sequential basis, the largest contributions came from consumer electronics and logistics.
• Gross margin was 78% for Q2-17, 76% for Q2-16 and 79% for Q1-17. Gross margin increased year-on-year due to cost efficiencies related to higher sales volume and an inventory charge in Q2-16 that did not repeat.
• Research, Development & Engineering (RD&E) expenses increased 19% from Q2-16 and 3% from Q1-17. RD&E increased both year-on-year and sequentially due to higher employee-related costs, including the addition of new engineering personnel from the company’s recent acquisitions.
• Selling, General & Administrative (SG&A) expenses increased 23% from Q2-16 and 13% from Q1-17. SG&A increased both year-on-year and sequentially primarily due to higher personnel-related costs. Investments were principally in the sales organization, but also included additions to G&A to support future growth. Commissions, bonus accrual and travel costs increased as a result of higher headcount and growth in the business. Higher stock option expense and spending related to the new ERP system also contributed to the year-on-year increase.
• Investment and other income was $1,969,000 in Q2-17, $1,669,000 in Q2-16 and $2,282,000 in Q1-17. Investment income increased both year-on-year and sequentially, primarily as a result of higher yields on invested balances. Offsetting the increase in Q2-17 is an expense associated with changes to the fair value of contingent consideration related to recent acquisitions. In Q2-16 and Q1-17, the change in fair value generated income.
• The effective tax rate was 9% in Q2-17, 17% in Q2-16 and (16%) in Q1-17. Excluding discrete tax items, the rate was 18% in all periods presented (tax adjustments are summarized in Exhibit 2). Notably, Q1-17 and Q2-17 included a discrete tax benefit of $13 million ($0.15 per share) and $6 million ($0.07 per share), respectively, related to the exercise of employee stock options.

Balance Sheet Highlights – July 2, 2017

• Cognex’s financial position as of July 2, 2017 was very strong, with $765 million in cash and investments and no debt. Cash and investments increased by $20 million from the end of 2016, mainly as the result of $91 million in cash generated from operations and $35 million in cash received from the exercise of employee stock options. Offsetting those increases were $14 million in dividends paid to shareholders, payments of $26 million for recent acquisitions and $62 million spent to repurchase 732,000 shares of Cognex’s common stock. Cognex intends to continue to repurchase shares of its common stock in Q3-17, subject to market conditions and other relevant factors.
• Accounts receivable as of July 2, 2017 increased by $23 million, or 42%, from the end of 2016 due to the substantial revenue increase in Q2-17.
• Inventories increased by $9.5 million, or 35%, from the end of 2016 to support future expected growth.
• The increases as of July 2, 2017 in deferred costs (which are included in Other Assets on the balance sheet in Exhibit 3) and deferred revenue were due to the company’s progress in fulfilling certain purchase orders that are expected to be recognized as revenue largely in Q3.

Financial Outlook – Third Quarter of 2017

• Revenue for Q3-17 is expected to be between $250 million and $260 million. This range represents a substantial increase both year-on-year and sequentially due to higher anticipated revenue from the consumer electronics industry. Cognex believes that the majority of larger consumer electronics orders in 2017 will be recognized as revenue in Q3 as compared to 2016, when they were more evenly split between Q2 and Q3.
• Gross margin is expected to be in the mid-to-high 70% range, closer to the midpoint of the range as compared to the higher end reported in Q2-17.
• Operating expenses are expected to increase by approximately 10% on a sequential basis due to continued investments in growth activities and costs associated with the company’s recent acquisitions.
• The effective tax rate is expected to be 18% before discrete tax items.

• 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 that management employs 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, net income and earnings 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), and (2) certain one-time discrete events, such as tax adjustments. Cognex does not intend for non-GAAP financial measures to be considered in isolation, or 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.
