Safe harbor Forward-Looking Statements This presentation contains forward-looking statements within the meaning of the “safe harbor” provisions of the Private Securities Litigation Reform Act of 1995. These statements are subject to risks and uncertainties. All statements other than statements of historical fact or relating to present facts or current conditions included in this presentation are forward-looking statements. Forward-looking statements give our current expectations and projections relating to our financial condition, results of operations, plans, objectives, future performance and business. You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “anticipate,” “estimate,” “expect,” “project,” “seek,” “plan,” “intend,” “believe,” “will,” “may,” “could,” “continue,” “likely,” “should,” and other words. The forward-looking statements contained in this presentation are based on assumptions that we have made in light of our industry experience and our perceptions of historical trends, current conditions, expected future developments and other factors that we believe are appropriate under the circumstances. These statements are not guarantees of performance or results. These assumptions and our future performance or results involve risks and uncertainties (many of which are beyond our control). Important factors that could cause actual results to differ materially from those in the forward-looking statements include regional, national or global political, economic, business, competitive, market and regulatory conditions and the following: our inability to successfully leverage our existing client base by expanding the volume of claims reviewed and cross-selling additional solutions; improvements to healthcare claims and retail billing processes reducing the demand for our solutions or rendering our solutions unnecessary; healthcare spending fluctuations; our clients declining to renew their agreements with us or renewing at lower performance fee levels; inability to develop new clients; delays in implementing our solutions; system interruptions or failures, including cyber-security breaches, identity theft or other disruptions that could compromise our information; our failure to innovate and develop new solutions for our clients; our failure to comply with applicable privacy, security and data laws, regulations and standards; changes in regulations governing healthcare administration and policies, including governmental restrictions on the outsourcing of functions such as those that we provide; loss of a large client; consolidation among healthcare payers or retailers; slow development of the healthcare payment accuracy market; negative publicity concerning the healthcare payment industry or patient confidentiality and privacy; significant competition for our solutions; our inability to protect our intellectual property rights, proprietary technology, information, processes and know-how; compliance with current and future regulatory requirements; declines in contracts awarded through competitive bidding or our inability to re-procure contracts through the competitive bidding process; our failure to accurately estimate the factors upon which we base our contract pricing; our inability to manage our growth; our inability to successfully integrate and realize synergies from the merger of Connolly Superholdings, Inc. and iHealth Technologies, Inc. in May 2014 or any future acquisitions or strategic partnerships; our failure to maintain or upgrade our operational platforms; our failure to renew our Medicare Recovery Audit Contractor program contracts or if the terms of the Medicare RAC program contracts are substantially changed; our rebranding may not be successful; litigation, regulatory or dispute resolution proceedings, including claims or proceedings related to intellectual property infringements; our inability to expand our retail business; our inability to manage our relationships with information suppliers, software vendors or utility providers; fluctuation in our results of operations; changes in tax rules; risks associated with international operations; our inability to realize the book value of intangible assets; our success in attracting and retaining qualified employees and key personnel; general economic, political and market forces and dislocations beyond our control risks related to our substantial indebtedness and holding company structure; volatility in bank and capital markets; our status as a controlled company and as an emerging growth company; and provisions in our amended and restated certificate of incorporation.. Additional factors or events that could cause our actual performance to differ from these forward-looking statements may emerge from time to time, and it is not possible for us to predict all of them. Should one or more of these risks or uncertainties materialize, or should any of our assumptions prove incorrect, our actual financial condition, results of operations, future performance and business may vary in material respects from the performance projected in these forward-looking statements. Any forward-looking statement made by us in this presentation speaks only as of the date on which it is made. We undertake no obligation to publicly update or revise any forward-looking statement, whether as a result of new information, future developments or otherwise, except as may be required by law. Market data and industry information used throughout this presentation are based on management’s knowledge of the industry and the good faith estimates of management. We also relied, to the extent available, upon management’s review of independent industry surveys and publications and other publicly available information prepared by a number of third party sources. All of the market data and industry information used in this presentation involves a number of assumptions and limitations, and you are cautioned not to give undue weight to such estimates. Although we believe that these sources are reliable, we cannot guarantee the accuracy or completeness of this information, and we have not independently verified this information. While we believe the estimated market position, market opportunity and market size information included in this presentation are generally reliable, such information, which is derived in part from management’s estimates and beliefs, is inherently uncertain and imprecise. Projections, assumptions and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described above. These and other factors could cause results to differ materially from those expressed in our estimates and beliefs and in the estimates prepared by independent parties. Non-GAAP Financial Measures We present Adjusted EBITDA and Free Cash Flow to help us describe our operating performance. Our presentation of Adjusted EBITDA and Free Cash Flow are intended as a supplemental measures of our performance that are not required by, or presented in accordance with, U.S. generally accepted accounting principles (“GAAP”). Adjusted EBITDA should not be considered as an alternative to operating income (loss), net income (loss), earnings per share or any other performance measures derived in accordance with U.S. GAAP as measures of operating performance or operating cash flows or as measures of liquidity. Our presentation of Adjusted EBITDA and Free Cash Flow should not be construed to imply that our future results will be unaffected by these items. See the Appendix to this presentation for a reconciliation of Adjusted EBITDA to net income (loss). 2
