Management Commentary

“Building on the momentum generated over the past several quarters, CRA delivered strong financial results in the second quarter of fiscal 2016 highlighted by the highest quarterly revenue in the past six years and a companywide utilization of 76%,” said Paul Maleh, CRA’s President and Chief Executive Officer.

“For the second quarter of fiscal 2016, we grew non-GAAP revenue by 9.2% to $82.5 million while driving non-GAAP Adjusted EBITDA margin to 17.3%,” Maleh said. “Our performance was led by more than 20% revenue growth year-over-year in each of our Auctions & Competitive Bidding, Energy, Finance, Intellectual Property, and Marakon practices. International operations also continued to deliver solid performance, led by our Antitrust & Competition Economics and Marakon practices.”

“We strive to be good stewards of the firm’s financial resources with a balanced capital allocation strategy,” Maleh said. “During the second quarter, we continued to invest in our business while repurchasing approximately 673,000 shares of common stock for approximately $16.2 million.”

Outlook and Financial Guidance

“We are growing our team of highly talented consultants and are well-positioned to capitalize on demand for CRA’s services,” Maleh said. “Positive trends in project lead flow and new project originations observed over the past year continued in the second quarter. While we are encouraged by our performance in the first half of fiscal 2016, we remain mindful that uncertainties around global economic conditions and short-term challenges arising from the integration of newly hired professionals can adversely impact our business in the quarters ahead.”

On a constant currency basis relative to fiscal 2015, CRA is affirming its previously provided fiscal 2016 guidance for non-GAAP revenue in the range of $312 million to $322 million and non-GAAP Adjusted EBITDA margin in the range of 15.8% to 16.6%.

CRA does not provide reconciliations of its non-GAAP revenue and Adjusted EBITDA margin guidance to the GAAP comparable financial measures because CRA is unable to estimate with reasonable certainty the financial results of its NeuCo subsidiary, the timing and amount of forgivable loans issued for talent acquisition, share-based compensation expense, unusual gains or charges, foreign exchange rates, and the resulting effect of these items on CRA’s taxes without unreasonable effort. These items are uncertain, depend on various factors, and may have a material effect on CRA’s results computed in accordance with GAAP. A reconciliation between the historical GAAP and non-GAAP financial measures presented in this release is provided in the financial tables at the end of this release, and further information regarding the non-GAAP measures presented in this release is provided below under the heading “Non-GAAP Financial Measures.”

NON-GAAP FINANCIAL MEASURES

In addition to reporting its financial results in accordance with U.S. generally accepted accounting principles, or GAAP, CRA has also provided in this release non-GAAP financial information. CRA believes that the use of non-GAAP measures in addition to GAAP measures is a useful method of evaluating its results of operations. CRA believes that presenting its financial results excluding the results of its NeuCo subsidiary, certain non-cash and/or non-recurring charges, and the other items identified below, and including presentations of Adjusted EBITDA and comparisons on a constant currency basis, are important to investors and management because they are more indicative of CRA’s ongoing operating results and financial condition. These non-GAAP financial measures should be considered in conjunction with, but not as a substitute for, the financial information presented in accordance with GAAP, and the results calculated in accordance with GAAP and

3

reconciliations to those results should be carefully evaluated. The non-GAAP financial measures used by CRA may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. Specifically, for the second quarter of fiscal 2016, the second quarter of fiscal 2015, the year-to-date period ended as of the second quarter of fiscal 2016, and its full 2016 fiscal year guidance, CRA has excluded NeuCo’s results, and for the year-to-date period ended as of the second quarter of 2015, CRA has excluded NeuCo’s results and a non-cash charge relating to an increased liability for a future contingent consideration payment relating to a prior acquisition. Also, in calculating “Adjusted EBITDA” from net income (loss) attributable to CRA for these fiscal periods and for purposes of the full 2016 fiscal year guidance for Adjusted EBITDA margin, CRA has excluded net income (loss) attributable to noncontrolling interest (net of tax), interest expense (income), net, provision for income taxes, other expense (income), net, and the following non-cash expenses: depreciation and amortization, share-based compensation expenses, and amortization of forgivable loans.

Finally, CRA believes that fluctuations in foreign currency exchange rates can significantly affect its financial results. Therefore, CRA provides a constant currency presentation to supplement disclosures regarding its results of operations and performance. CRA calculates constant currency amounts by converting its applicable fiscal period local currency financial results using the prior fiscal year’s corresponding period exchange rates. CRA has presented in this press release its GAAP and non-GAAP revenue, net income, and earnings per diluted share, and its Adjusted EBITDA, for the second quarter of fiscal 2016 on a constant currency basis relative to the second quarter of fiscal 2015, and its guidance for fiscal 2016 non-GAAP revenue and Adjusted EBITDA margin on a constant currency basis relative to fiscal 2015.

Statements in this press release concerning our future business, operating results and financial condition, including guidance on future non-GAAP revenue and non-GAAP Adjusted EBITDA margin, and statements regarding our capital allocation strategy, the future continuation of current trends, our future hiring, or our consultants’ ability to capitalize on demand for our services, and statements using the terms “looking  forward,” “expect,” “trends,” “believes,” “should,” or similar expressions, are “forward-looking” statements as defined in Section 21 of the Exchange Act. These statements are based upon our current expectations and various underlying assumptions.

factors and uncertainties. Our actual non-GAAP revenue and non-GAAP Adjusted EBITDA margin in fiscal 2016 on a constant currency basis relative to fiscal 2015 could differ materially from the guidance presented herein, and our actual performance and results may differ materially from the performance and results contained or implied by the other forward-looking statements made herein, due to many important factors. These factors include, but are not limited to, the loss of key employee consultants or non-employee experts; their failure to generate engagements for us; our inability to attract, hire or retain qualified consultants, or to integrate and utilize existing consultants and personnel; the unpredictable nature and risk of litigation-related projects; dependence on the growth of our management consulting practice; the change in demand for our services; the potential loss of clients; changes in the law that affect our practice areas; global economic conditions including less stable political and economic environments; civil disturbances or other catastrophic events that reduce business activity; foreign exchange rate fluctuations; intense competition; our attributable annual cost savings; changes in our effective tax rate; share dilution from our stock-based compensation; integration and generation of existing and new clients; unanticipated expenses and liabilities; the risk of impairment write downs to our intangible assets, including goodwill; risks associated with acquisitions (past, present, and future); risks inherent in international operations; changes in accounting standards, rules and regulations; integration and management of new and existing offices; the ability of clients to terminate engagements with us on short notice; our ability to collect on forgivable loans should any become due; general economic conditions; the performance of our NeuCo  subsidiary or the impact of the sale of its business; and professional and other legal liability. Further information on these and other potential factors that could affect our future business, operating results, and financial condition is included in our periodic filings with the Securities and Exchange Commission, including risks under the heading “Risk Factors.” We cannot guarantee any future results, levels of activity, performance, or achievement.
