inTEST REPORTS 2018 SECOND QUARTER FINANCIAL RESULTS

MOUNT LAUREL, NJ, August 2, 2018 - 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 second quarter ended June 30, 2018.

2018 Second Quarter Summary

2018 Six Month Year-to-Date Summary

“Second quarter operating results were exceptionally strong, driven by orders for our broad-based solutions across test and industrial manufacturing,” commented inTEST President & CEO James Pelrin. “Net revenues of $21.1 million increased 12% sequentially and exceeded our guidance. Gross margin increased from 50% in the first quarter to 52%, coming in at the high end of our guidance, and net earnings per diluted share increased and exceeded our guidance. Net earnings of $0.39 increased by $0.35 sequentially, and adjusted net earnings of $0.34 increased by $0.12. The robust demand associated with the semiconductor industry, with automotive sensors, mobility technologies and Internet of Things (IoT), continues to benefit our semiconductor test business, while non-semi business drivers included solid demand from automotive, industrial and defense/aerospace markets.”

Mr. Pelrin added, “We continue to expand our customer base in the markets we serve, while growing inTEST’s footprint in additional thermal test and industrial markets. Looking forward, our long-term drivers remain squarely in place and we see solid opportunities as we take advantage of robust markets where we have a strong focus: semi with its super cycle, IoT, automotive including electric vehicle, optical transceiver and consumer markets. We will continue to direct our resources in these key markets to further grow market share and broaden our customer base.

“Our leadership in thermal continues to increase, with greater opportunities at Ambrell from our OEM partners and end-user projects. In our iTS business we expect continued solid bookings in the semiconductor, defense/aerospace and telecommunications markets, as well as additional demand driven by increased investment by a key industrial energy customer. We expect demand for our semi related products to remain brisk, benefitting both the iTS and EMS divisions.”

Mr. Pelrin concluded, “With the momentum of inTEST’s solid performance in the first half of the year, our commitment to focus resources in growth market areas, and the overall positive global economic climate, we are creating the conditions for our long-term success and a strong 2018.”

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, adjusted net earnings per diluted share and adjusted EBITDA. 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 weighted average shares outstanding. Adjusted EBITDA is derived by adding interest expense, income tax expense, depreciation and 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. These results are provided as a complement to results provided in accordance with GAAP. Adjusted net earnings, adjusted net earnings per diluted share and adjusted EBITDA 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 from net earnings and net earnings per diluted share to adjusted net earnings and adjusted net earnings per diluted share and from net earnings to adjusted EBITDA, 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.
