CHARLES RIVER ASSOCIATES ANNOUNCES THIRD-QUARTER
FISCAL 2009 FINANCIAL RESULTS

BOSTON, October 1, 2009 – Charles River Associates (NASDAQ: CRAI), a worldwide leader in providing management, economic, and financial consulting services, today announced financial results for its fiscal third quarter, the 16 weeks ended September 4, 2009.

Revenue for the third quarter of fiscal 2009 was $89.3 million compared with $111.2 million for the third quarter of fiscal 2008. GAAP net income for the third quarter of fiscal 2009 was $2.9 million, or $0.27 per diluted share, compared with GAAP net income of $4.2 million, or $0.39 per diluted share, in the third quarter of fiscal 2008. Non-GAAP revenue for the third quarter of fiscal 2009 was $86.3 million, compared with $111.2 million for the third quarter of fiscal 2008. Non-GAAP net income was $3.4 million, or $0.31 per diluted share, compared with $3.5 million, or $0.32 per diluted share, in the third quarter last year. A complete reconciliation between revenue, net income and net income per share on a GAAP and non-GAAP basis for the third quarters of fiscal 2009 and fiscal 2008 is provided in the financial tables at the end of this news release.

Comments on the Third Quarter

“The ongoing uncertainty of the global recession negatively affected our third-quarter results,” said James C. Burrows, CRA’s President and Chief Executive Officer. “While it appeared that some of our key markets were beginning to loosen up at the end of the second quarter, the third quarter was a challenging and disappointing period. Many clients continued to restrict spending, and major litigation cases and consulting projects have stalled or are moving at a more deliberate pace. As a result, a number of our larger

practices did not meet our expectations this quarter. Consequently, our utilization rate in the third quarter declined to 69 percent from 71 percent in the sequential second quarter.”

“Although our overall results did not meet our expectations, we did experience positive performance in certain areas,” Burrows said. “For example, our Forensics and Labor & Employment practices improved year-over-year, and our Energy practice improved over the second quarter, partly due to opportunities presented by the economic downturn and global economic changes. While work in the chemicals sector has been particularly hard hit in recent quarters, third-quarter results were up on a sequential basis in our North American Global Industrial Consulting Practice. We experienced an uptick in demand in the U.S. for chemicals-related work, M&A activities, and the accelerated policy debate around climate change. In the Middle East, we experienced some unexpected delays in obtaining signed contracts for work that we had been awarded earlier; we now expect much of those revenues to be realized in the next few quarters.”

“During the quarter, we announced the acquisition of Marakon Associates, a leading strategy consulting firm known for its pioneering work in value-based management,” Burrows said. “The integration of Marakon has been proceeding smoothly and the practice’s contributions in the quarter were on plan. This acquisition has provided additional depth and scale to our capabilities, enabling us to broaden our client offerings in key markets. We look forward to further capitalizing on this important addition to CRA in the quarters ahead.”

“From a bottom-line perspective, we continued to tightly manage our expenses to better reflect client demand,” Burrows said. “Excluding the addition of the Marakon personnel, in the third quarter we reduced our total consultant headcount by 25 positions, even as we continue to make selective senior hires aimed at driving revenue growth. Factoring out the effect of the NeuCo consolidation on our results, we reduced SG&A in the third quarter by nearly $5 million on a year-over-year basis. We have significantly streamlined our operations during the past year and have greatly lowered our cost structure through organizational restructurings, practice divestitures and office closings. We concluded the third quarter of fiscal 2009 with $104.8 million in cash and equivalents.”

CRA’s tax rate for the third quarter was 51.8 percent on a GAAP basis and 36.0 percent on a non-GAAP basis as compared to 60.9 percent on a GAAP basis and 65.0 percent on a non-GAAP basis for the third quarter of 2008. The significantly improved non-GAAP tax rate reflects anticipated improved operating performance in Europe and the Middle East region, including Marakon’s positive contribution.

Accounting Review

The Company announced today that it has completed an independent, voluntary review of its accounting for acquisition related earn-out payments and no material corrections are required to its previously filed financial statements. For additional details, please see the Company’s Form 8-K report related to the matter, which was filed today.

Outlook

“Looking ahead, while long-term trends continue to favor CRA, we anticipate a challenging business environment in the near-term,” Burrows said. “We believe that our market positioning in the areas we serve is strong, and that our revenues will increase as general business conditions improve. We do expect that practices that have experienced good momentum in recent quarters will continue to grow. We are encouraged by the early contributions from Marakon and activity levels in our Middle East business, where project leads and proposal streams remain strong.”

“In the interim, we will continue to drive our three-pronged focus, which is to aggressively pursue top-line growth within each practice, enhance margins through continued cost controls and drive operating cash flow.” Burrows said. “We launched a new marketing initiative – a return to the Charles River Associates name for branding purposes – that will help us to raise further awareness of our Company.”

“We continue to be a preferred provider for the types of services we offer. However, in these challenging economic times, it may take some time for client demand to fully rebound in both our litigation and consulting practices. Nevertheless, our underlying fundamentals are solid, our reputation is strong and there continue to be sizeable long-term

opportunities for CRA. We believe as our markets normalize, global, economic and legal trends will stimulate long-term demand for CRA’s broad range of consulting services,” Burrows concluded.

NON-GAAP FINANCIAL MEASURES

In addition to reporting its financial results in accordance with U.S. generally accepted accounting principles, or GAAP, the Company has also provided in this release non-GAAP revenue, non-GAAP net income, non-GAAP net income per share, non-GAAP SG&A, and non-GAAP tax rate. The Company believes the use of non-GAAP measures in addition to GAAP measures is an additional useful method of evaluating its results of operations. The Company believes that presenting its financial results excluding these restructuring costs,

foreign currency exchange gain/loss attributable to the liquidation of the Company’s Australia and New Zealand-based operations, gain from convertible bond repurchases, and NeuCo’s results is important to investors and management because it is more indicative of its 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 expected results calculated in accordance with GAAP and reconciliations to those expected results should be carefully evaluated. The non-GAAP financial measures used by the Company may be calculated differently from, and therefore may not be comparable to, similarly titled measures used by other companies. Specifically, for the third quarter of fiscal 2009, the Company has excluded NeuCo’s results. For the third quarter of fiscal 2008, the Company excluded the foreign exchange gain attributable to the substantial liquidation of the Company’s New Zealand-based operations as well as NeuCo’s results.

Statements in this press release concerning the future business, operating results, estimated cost savings, and financial condition of the Company and statements using the terms “anticipates,” “believes,” “expects,” “should,” or similar expressions, are “forward-looking” statements as defined in the Private Securities Litigation Reform Act of 1995. These statements are based upon management’s current expectations and are subject to a number of factors and uncertainties. Information contained in these forward-looking statements is inherently uncertain and actual performance and results may differ materially due to many important factors. Such factors that could cause actual results to differ materially from any forward-looking statements made by the Company include, among others, the Company’s restructuring costs and attributable annual cost savings, changes in the Company’s effective tax rate, share dilution from the Company’s convertible debt offering and stock-based compensation, dependence on key personnel, attracting and retaining qualified consultants, dependence on outside experts, utilization rates, factors related to its acquisitions, including integration of personnel, clients, offices, and unanticipated expenses and liabilities, the risk of impairment write downs to the Company’s intangible assets, including goodwill, if the Company’s enterprise value declines below certain levels, risks associated with acquisitions it may make in the future,

risks inherent in international operations, the performance of NeuCo, changes in accounting standards, rules and regulations, changes in the law that affect its practice areas, management of new offices, the potential loss of clients, the ability of customers to terminate the Company’s engagements on short notice, dependence on the growth of the Company’s business consulting practice, the unpredictable nature of litigation-related projects, the ability of the Company to integrate successfully new consultants into its practice, general economic conditions, intense competition, risks inherent in litigation, and professional liability. Further information on these and other potential factors that could affect the Company’s financial results is included in the Company’s filings with the Securities and Exchange Commission. The Company cannot guarantee any future results, levels of activity, performance or achievement. The Company undertakes no obligation to update any of its forward-looking statements after the date of this press release.
