CRA INTERNATIONAL REPORTS THIRD QUARTER FISCAL 2006
FINANCIAL RESULTS

Revenue Increase of 15.7 Percent Driven by Growth Across Practices,
Strength in International Business, and BBG Acquisition

BOSTON, September 28, 2006 — CRA International, Inc. (Nasdaq: CRAI), a worldwide leader in providing economic, financial, and management consulting services, today reported financial results for its third quarter of fiscal 2006, the sixteen weeks ended September 1, 2006.

Revenue for the third quarter of fiscal 2006 increased 15.7 percent to $107.0 million from $92.5 million for the third quarter of fiscal 2005. Net income for the third quarter of fiscal 2006 was $8.7 million, or $0.71 per diluted share, compared with $7.9 million, or $0.66 per diluted share, in the comparable period last year. Weighted average diluted shares outstanding used to calculate earnings per share in the third quarter of fiscal 2006 were 12.3 million, versus 12.0 million in the third quarter of fiscal 2005.

In fiscal 2006, CRA began to expense stock-based compensation in accordance with Financial Accounting Standards Board Statement No. 123R (“123R”). Included in the Company’s third quarter of fiscal 2006 net income and diluted earnings per share amounts were approximately $950,000 and $0.08 per share, respectively, of stock-based compensation.

Revenue for the first three quarters of fiscal 2006 was $263.6 million, an 18.9 percent increase from $221.7 million in the same period a year earlier. Net income for the first three quarters of fiscal 2006 was $21.1 million, a 17.3 percent increase from $18.0 million in the first three quarters of fiscal 2005. Earnings per diluted share were $1.73 in the first three quarters of fiscal 2006, compared with $1.58 in the first three quarters of fiscal 2005. Included in the Company’s first three quarters of fiscal 2006 net income and diluted earnings per share amounts were approximately $2.5 million and $0.21 per share, respectively, of stock-based compensation. Weighted average diluted shares outstanding used to calculate earnings per share in the first three quarters of fiscal 2006 were 12.2 million, versus 11.4 million in the first three quarters of fiscal 2005.

Comments on the Third Quarter

“CRA’s third-quarter performance reflects strong contributions from a number of our litigation and business consulting practices, resulting in overall revenue growth of nearly 16 percent,” said James C. Burrows, CRA International’s president and chief executive officer. “The diversity of our revenue base is a significant asset for CRA and enables us to take advantage of the changing dynamics within our functional practices and vertical markets. During the third quarter, we experienced considerable growth in our Competition and Finance practices, as well as in Transfer Pricing, which benefited from the Ballentine Barbera Group (“BBG”) acquisition earlier in the quarter. In addition, CRA’s share in NeuCo’s third-quarter loss was approximately $500,000. The NeuCo loss included a one-time charge attributable to a legal settlement incurred in connection with an acquisition made by NeuCo. As of this quarter, NeuCo is no longer consolidated in our financials.”

“We continued to see significant contributions from our international consulting businesses,” Burrows said. “Our results in the quarter demonstrate our ongoing success in generating demand for CRA’s services on a global basis.”

“Utilization in the third quarter of 2006 improved to 76 percent from 74 percent in the year ago period,” said Burrows. “In a quarter that is traditionally challenging due to the summer holiday season, we continued to be on track towards our goal of achieving fiscal 2006 utilization of 78 to 80 percent.”

Outlook and Financial Guidance

“For the fourth quarter of 2006, we anticipate that global, economic and legal trends will continue to stimulate demand for CRA’s broad range of specialized consulting expertise and our recognized staff of elite professionals,” Burrows said. “Based on this outlook and current market conditions, we expect continued growth across the majority of our practice areas.”

CRA continues to anticipate revenue growth for fiscal 2006 in the range of 18-20 percent. In fiscal 2006, CRA expects a 29-30 cents-per-share impact from stock-based compensation. Based on year-to-date results, CRA anticipates a slightly lower effective tax rate for the year compared to its prior guidance of approximately 42-43 percent. As a result of the expected slightly lower tax rate, CRA anticipates net income for the full year to be slightly above the high end of the previous guidance of $26.5 million to $27.5 million, or $2.18 to $2.27 per diluted share, including the impact of stock-based compensation.

Fiscal 2006 EPS assumes an average diluted share count of 12.2 million shares for the year and assumes a stock price of $46.05 for the remainder of the year, which was

derived from the average of the past 10 trading days. Deviations from this stock price will cause earnings per share to vary based on share dilution from CRA’s stock options and convertible bonds.
