21 Appendix 21

22 Explanation of Use of Non - GAAP Measures 22 Wireless Telecom Group, (the “Company”), reports its financial results in accordance with generally accepted accounting principles (“GAAP”) . Management believes, however, that certain non-GAAP financial measures used in managing the Company’s business may provide users of this financial information with additional meaningful comparisons between current results and prior reported results . Certain of the information set forth herein constitutes non-GAAP financial measures within the meaning of Regulation G adopted by the Securities and Exchange Commission . We have presented herein a reconciliation of these measures to the most directly comparable GAAP financial measure . The non-GAAP measures presented herein may not be comparable to similarly titled measures presented by other companies . The foregoing measures do not serve as a substitute and should not be construed as a substitute for GAAP performance, but provide supplemental information concerning our performance that our investors and we find useful . The Company defines EBITDA as its net earnings before interest, taxes, depreciation and amortization . “Adjusted EBITDA” is EBITDA excluding our stock compensation expense, restructuring charges, acquisition expenses, integration expenses, the one - time non - cash inventory impairment charges, unrealized and realized foreign exchange gains and losses, and other non - recurring costs and includes cash received in 2018 related to revenue that would have been recognized in 2018 but for the adoption of ASU 606 . A reconciliation of net income to non - GAAP Adjusted EBITDA set forth on pages 22 - 23 above . The Company views Adjusted EBITDA as an important indicator of performance, consistent with the manner in which management measures and forecasts the Company’s performance . We believe Adjusted EBITDA is an important performance metric because it facilitates the analysis of our results, exclusive of certain non-cash items and non - recurring items, including items which do not directly correlate to our business operations . The Company believes that Adjusted EBITDA metrics provide qualitative insight into our current performance ; we use these measures to evaluate our results, the performance of our management team and our management’s entitlement to incentive compensation ; and we believe that making this information available to investors enables them to view our performance the way that we view our performance and thereby gain a meaningful understanding of our core operating results, in general, and from period to period .
