inTEST REPORTS 2017 THIRD QUARTER FINANCIAL RESULTS

MOUNT LAUREL, NJ, November 2, 2017 - inTEST Corporation (NYSE American: INTT), an independent designer, manufacturer and marketer of thermal management products and semiconductor automatic test equipment (ATE) interface solutions, today announced financial results for the quarter ended September 30, 2017.

2017 Third Quarter Summary

“We again delivered solid financial results,” commented inTEST Executive Chairman, President & CEO Robert E. Matthiessen. “We marked the Company’s 32nd consecutive quarter of profitability, with GAAP earnings of $0.19 per diluted share and non-GAAP adjusted net earnings of $0.20 per diluted share. Third quarter revenue grew 9% sequentially and 60% year-over-year, and bookings increased 21% sequentially and 56% year-over-year. Excluding the impact of the acquisition of Ambrell, third quarter revenue declined 11% sequentially and increased 15% year-over-year, and bookings declined 9% sequentially and 1% year-over-year, reflecting the usual seasonal softening. We ended the quarter with a backlog of $11.3 million.”

Mr. Matthiessen added, “There is a natural ebb and flow to the test industry, with strength in the first half of the year typically balanced by seasonal declines in the second half of the year; and while the semiconductor market continues to be very healthy, with fab spending for 2017 and 2018 expected to be at historic levels, it remains a cyclical industry and is a market upon which we have strategically lessened our historic dependence. In the third quarter, 47% of net revenues were derived from non-ATE, compared with 26% a year ago, due in large part to the acquisition of Ambrell, which has also served to broaden our customer diversification and has increased our footprint in several growth markets. Ambrell’s induction heating technology complements our 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 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 and a stronger 2018.”

2017 Fourth Quarter Financial Outlook

inTEST expects that net revenues for the fourth quarter of 2017 will be in the range of $17.5 million to $18.5 million and that on a GAAP basis, net earnings per diluted share will range from $0.11 to $0.15. On a non-GAAP basis, adjusted net earnings per diluted share will range from $0.13 to $0.17. 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. These non-GAAP performance measures include adjusted net earnings and adjusted net earnings per diluted share. Adjusted net earnings is derived by adding acquired intangible amortization, adjusted for the related income tax expense, to net earnings and removing any change in the fair value of our contingent consideration liability from 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 investors with meaningful supplemental information regarding our baseline performance before acquired intangible amortization charges and changes in the estimate of future consideration that may be paid out related to prior acquisitions as these expenses or income items may not be indicative of our current core business or future outlook. These non-GAAP performance measures are used by management 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 net earnings per diluted share, which are discussed in this earnings release, is contained in the tables below. The non-GAAP performance measures discussed in this earnings release may not be comparable to similarly titled measures used by other companies. The presentation of non-GAAP measures is not meant to be considered in isolation, as a substitute for, or superior to, financial measures or information provided in accordance with GAAP.
