inTEST Executive Chairman, President and Chief Executive Officer Robert E. Matthiessen commented, "We are very pleased with our results for the second quarter. On the heels of an exceptionally strong first quarter, second quarter revenue increased 33% year-over-year, excluding the impact of the additional net revenues from the acquisition of Ambrell, and we marked the Company's 31st consecutive quarter of profitability."

Mr. Matthiessen added, "We are seeing immediate benefits from the recently closed acquisition. Ambrell's induction heating technology complements our current thermal technologies and firmly establishes our position in industrial markets with a diverse customer base in a broader manufacturing space, including in many emerging markets, consumer product packaging, fiber-optic, automotive and other markets. We are well positioned to capture market share in the markets we serve, while expanding inTEST's footprint in additional thermal test and industrial markets. As we head into the second half of 2017, we anticipate seasonal declines, consistent with our peers, given the strength in the test industry in the first part of this year. As we continue to execute on our differentiated product strategy, we believe the conditions for our long-term success remain firmly in place and we are solidly on track for a strong 2017."

2017 Third Quarter Financial Outlook
inTEST expects that net revenues for the third quarter of 2017 will be in the range of $17.5 million to $18.5 million and that on a GAAP basis, earnings per diluted share will range from $0.12 to $0.16. This outlook is based on the Company's current views with respect to operating and market conditions and customers' forecasts, which are subject to change.

Non-GAAP Results
In addition to disclosing results that are determined in accordance with GAAP, we also disclose non-GAAP performance measures.

Adjusted net earnings is derived by adding acquired intangible amortization to net earnings. Adjusted net earnings per diluted share is derived by dividing adjusted net earnings by diluted average shares outstanding. These results are provided as a complement to results provided in accordance with GAAP. Adjusted net earnings and adjusted net earnings per diluted share are non-GAAP performance measures presented to provide meaningful supplemental information regarding our baseline performance before acquired intangible amortization charges that may not be indicative of our current core business or future outlook. These non-GAAP performance measures are used to make operational decisions, to forecast future operational results, and for comparison with our business plan, historical operating results and the operating results of our peers. A reconciliation of net earnings and net earnings per diluted share to adjusted net earnings and adjusted earnings per diluted share, which are discussed in this earnings release, is contained in the tables that follow. The non-GAAP performance measures discussed in this earnings release may not be comparable to similarly titled measures used by other companies.
