Use of Non-GAAP (Generally Accepted Accounting Principles) Financial Measures In addition to reporting financial results in accordance with generally accepted accounting principles, or GAAP, the Company provides adjusted EBITDA, adjusted income, adjusted EPS, free cash flow, organic revenue and acquired revenue which are non-GAAP financial measures. Adjusted EBITDA, adjusted income, and adjusted EPS exclude certain non-cash and other specified charges. The Company believes these non-GAAP financial measures are useful to help investors better understand its past financial performance and prospects for the future. However, these non-GAAP measures should not be considered in isolation or as a substitute for financial information provided in accordance with GAAP. Management believes these non-GAAP measures assist in providing a more complete understanding of the Company's underlying operational results and trends, and management uses these measures along with the corresponding GAAP financial measures to manage the Company's business, to evaluate its performance compared to prior periods and the marketplace, and to establish operational goals. A reconciliation of GAAP to non-GAAP financial results discussed in this presentation is contained in the Appendix hereto. © 2019 Mercury Systems, Inc. 2#3#4#5Mercury's financial profile demonstrates our unique strategy # of Companies 1,109 359 117 48 ALL NYSE AND NASDAQ U.S. LISTED COMPANIES WITH MARKET CAPITALIZATION BETWEEN $1B - $5B ● LTM EBITDA Margin >20% Revenue CAGR >10% 4-Year LTM Revenue Growth >20% TIER 2 DEFENSE INDEX 13% 4% 8% mercury systemsTM 23% Margin 29% Growth 38% Growth Notes: • LTM figures for Mercury are based on the trailing four fiscal quarters using information reported in Mercury's Form 10-Ks, Form 10-Qs and/or most recent earnings release.
