CHARLES RIVER ASSOCIATES (CRA) ANNOUNCES SECOND-QUARTER
FISCAL 2010 FINANCIAL RESULTS

Company Momentum Shifts Favorably as Non-GAAP Revenue

and Profitability Improve from First Quarter

BOSTON, June 10, 2010 — Charles River Associates (NASDAQ: CRAI), a worldwide leader in providing management, economic and financial consulting services, today announced financial results for its fiscal second quarter, the twelve weeks ended May 14, 2010.

Revenue for the second quarter of fiscal 2010 was $68.1 million, compared with $72.0 million for the second quarter of fiscal 2009 and $58.8 million in the first quarter of fiscal 2010. Non-GAAP revenue for the second quarter of fiscal 2010 was $66.3 million, compared with $69.3 million in the same period of fiscal 2009 and $57.8 million in the first quarter of fiscal 2010.

The net loss for the second quarter of fiscal 2010 was $1.5 million, or $0.14 per share, compared with net income of $1.2 million, or $0.11 per diluted share, in the second quarter of fiscal 2009, and net income of $266,000, or $0.02 per diluted share, in the first quarter of fiscal 2010. The net loss for the second quarter of fiscal 2010 included a pre-tax restructuring charge of $5.0 million and a pre-tax charge of $425,000 related to the repurchase of convertible bonds. Excluding these charges and the effect of the Company’s NeuCo subsidiary, non-GAAP net income for the second quarter of fiscal 2010 was $2.0 million, or $0.19 per diluted share, compared with non-GAAP net income of $3.0 million, or $0.28 per diluted share, in the second quarter of fiscal 2009, and $446,000, or $0.04 per diluted share, in the first quarter of fiscal 2010.

A complete reconciliation between GAAP and non-GAAP financial information for the second quarters of fiscal 2010 and fiscal 2009, the first quarter of fiscal 2010, and the first two quarters of fiscal 2010 and fiscal 2009 is provided in the financial tables at the end of this release.

The Company ended the second quarter with cash and equivalents and short-term investments of $80.0 million, compared with $113.3 million at the end of the first quarter of fiscal 2010. The difference primarily reflects the payment of the fiscal 2009 bonuses in the second quarter and $15 million related to the repurchase of the Company’s convertible bonds.

Comments on the Second Quarter

“CRA’s non-GAAP revenue for the second quarter grew 15% from the sequential first quarter, driven by positive contributions from several practices within our litigation and management consulting service offerings,” said Paul Maleh, CRA’s President and Chief Executive Officer. “Our ability to achieve double-digit sequential revenue growth is notable, considering that we executed a series of restructuring activities during the second quarter. We expect these restructuring activities will yield annualized savings of approximately $9.3 million. As a result of these actions and an increased demand for our services, utilization improved to 65% from 60% in the first quarter. Although this remains below our target utilization rate, several practices have responded positively to the challenging environment. Across the Company, we are focused on maintaining the momentum gained during the second quarter.”

“As a result, our non-GAAP operating margin increased to 6.5% from 3.2% in the first quarter of fiscal 2010,” Maleh said. “On a non-GAAP basis, second-quarter SG&A as a percentage of revenue declined to 22.2%, compared with 25.3% in the first quarter. Our non-GAAP SG&A costs were flat sequentially while adding $8.5 million of revenue in the quarter. We will continue to work at reducing our SG&A expense while improving the support services provided to our consultants.”

Outlook

“We believe the underlying fundamentals of our business have improved from the slow start we experienced at the beginning of the fiscal year,” said Maleh. “CRA is continuing to win new engagements across a number of practice areas, and the cost reduction and strategic initiatives we implemented over the past two years have strengthened the foundation of our business. Looking forward, however, the impact of these positive factors may be tempered by the uncertain economic environment, as clients continue to be hesitant about spending on major consulting projects and the pace of litigation-related activity remains sluggish.”

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 financial information. 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, non-cash expenses related to the repurchase of its convertible bonds, 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 second quarter of fiscal 2010, the Company has excluded certain restructuring costs, expenses related to the repurchase of its convertible bonds and NeuCo’s results. For the first quarter of 2010, the Company has excluded NeuCo’s results. For the second quarter of fiscal 2009, the Company has excluded certain restructuring costs, expenses related to the repurchase of its convertible bonds and NeuCo’s results.

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 periodic filings with the Securities and Exchange Commission.

(3) During the twelve weeks ended May 14, 2010, the Company repurchased $15.0 million of its convertible bonds at a discount, however, under FASB Accounting Standards Codification Topic 470-20, “Debt”, this resulted in a $0.4 million loss on a pre-tax basis.
