Total Revenue vs. Adjusted EBITDA Margin1 Adjusted EBITDA is a non-GAAP financial measure. See Appendix for a reconciliation to the most comparable GAAP financial measure. Includes loss of two large clients. Today, no client represents >5% of service revenue (quarterly period ended September 30, 2015). Utilization 65.5% 75.6% 75.8% 71.5% 72.4% 76.7% 71.4% 1% change in Utilization = ~$1.5M change in service revenue 2 This presentation is © 2015 Edgewater Technology, Inc. – All Rights Reserved

Free Cash Flow1 Generation / Minimal Cap Ex Strong Cash Flow Free cash flow is a non-GAAP financial measure and is calculated as operating cash flow minus capital expenditures. See Appendix for a reconciliation to the most comparable GAAP financial measure. Free cash flow divided by enterprise value (reflective of the Company’s market capitalization, pricing as of the balance sheet date, less cash and cash equivalents). See Appendix for a calculation of this non-GAAP measure. Free cash flow in 2012 reflects the receipt of $3.25M in connection with a sale of IP to Microsoft. 1.4% Cash Flow Yield² Capital–Light Model Disciplined DSO Management This presentation is © 2015 Edgewater Technology, Inc. – All Rights Reserved

Edgewater 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 and certain of the information presented by the Company from time to time may constitute 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. As noted below, the foregoing measures have limitations and 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. Edgewater views Adjusted EBITDA and Free Cash Flow as important indicators of performance, consistent with the manner in which management measures and forecasts the Company’s performance. We believe Adjusted EBITDA measures are important performance metrics because they facilitate the analysis of our results, exclusive of certain non-cash items, including items which do not directly correlate to our existing business, providing specialty IT services. For instance, the exit of our former significant unrelated operations in 2000 and 2001 created significant net operating loss carry-forwards and deferred tax assets, and the tax provisions that we take under GAAP, for which there is no corresponding federal tax payment obligation for us, and the adjustments that we make to our deferred tax asset, based on the prospects and anticipated future profitability of our ongoing operations, can be significant and can obscure, either significantly, or in part, period-to-period changes in our core operating results. Likewise, we incur direct transaction costs related to acquisitions which are expensed in our GAAP financial statements. Our Adjusted EBITDA calculation excludes the effects of direct acquisition-related costs to facilitate an understanding of comparative period-to-period changes in our core operating results. Similarly, we incurred, and have excluded from our Adjusted EBITDA calculation, costs associated with the Fullscope Embezzlement Issue as we believe that the non-recurring nature of the costs associated with this issue makes comparison of our current and historical financial results difficult. Non-GAAP Financial Measures This presentation is © 2015 Edgewater Technology, Inc. – All Rights Reserved

We believe Free Cash Flow measures are important performance metrics because they provide us with a useful assessment of our liquidity and capital resources. The GAAP measure most directly comparable to Free Cash Flow is cash flow from operations. We use Free Cash Flow for the purpose of determining the amount of cash available for investment in our business, funding strategic acquisitions, repurchasing stock and other purposes. Our Free Cash Flow calculation is the result of cash flow from operations, less purchases of property and equipment. Because Free Cash Flow addresses the effect of capital expenditures that are not reflected in GAAP cash flow from operations, we believes that Free Cash Flow provides a useful assessment of our liquidity and capital resources. We believe that Adjusted EBITDA and Free Cash Flow metrics provide qualitative insight into our current performance; we use these measures to evaluate our results, performance of our management team and our management’s entitlement to incentive compensation (with respect to Adjusted EBITDA); 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.

Reconciliation to Non-GAAP Measures Adjusted EBITDA is a Non-GAAP financial measure and is not intended to be a financial measure that should be regarded as an alternative to, or more meaningful than, GAAP Net Income (Loss). The Adjusted EBITDA measure presented may not be comparable to similarly titled measures presented by other companies. Adjusted EBITDA is defined as net income less interest income and other, net, plus taxes, depreciation and amortization, stock-based compensation expense, adjustments to contingent consideration earned, goodwill impairment charges, direct acquisition costs, the Fullscope Embezzlement Issue costs and lease abandonment charges.
