“We continue to experience strong demand across our end markets, and by all measures 2017 was an outstanding year, further demonstrating our strong execution and operating leverage,” commented inTEST President & CEO James Pelrin. “Net revenue increased 66% and gross margin grew 120 basis points as a percentage of net revenue in 2017, compared to 2016. Increasing demand for our broad-based solutions across all of our business units fueled this growth; non-semi business drivers included solid advances in the automotive, telecom, and defense/aerospace markets, while our semiconductor test business was led by automotive sensors, mobility and the Internet of Things (IoT). We also marked the Company’s 8^th consecutive year of profitability, a metric of which we are very proud as it speaks to the discipline and dedication exhibited by every inTEST employee.”

Mr. Pelrin added, “We continue to see significant opportunities for growth. We are in an era of technological change, with disruptive technologies that are growing at higher rates than traditional markets, driven by a quest for manufacturing efficiencies, the flow of data, connectivity, and mobility. The automotive industry is one example where these technologies converge, providing opportunities for each inTEST business to meet the challenges inherent to the test and process industries. 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 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 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 weighted 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.
