CRA INTERNATIONAL REPORTS FIRST QUARTER 
FISCAL 2006 FINANCIAL RESULTS

Revenue Increases 17.5 Percent on Strong Performance in Litigation;
Net Income Grows 22 Percent as Utilization Reaches 78 Percent

BOSTON, March 16, 2006 — CRA International, Inc. (Nasdaq: CRAI), a worldwide leader in providing economic, financial, and management consulting services, today reported financial results for its first quarter ended February 17, 2006.

Revenue for the first quarter of fiscal 2006 increased 17.5 percent to $72.5 million from $61.7 million for the first quarter of fiscal 2005.  Net income for the first quarter of fiscal 2006 was $5.6 million, or $0.47 per diluted share, compared with $4.6 million, or $0.43 per diluted share, in the comparable period last year.  Weighted average diluted shares outstanding used to calculate earnings per share in the first quarter of fiscal 2006 were 12.1 million, versus 10.8 million in the first quarter of fiscal 2005.

In fiscal 2006, CRA has begun to expense stock-based compensation in accordance with Financial Accounting Standards Board Statement No. 123R (“123R”).  Included in the Company’s first quarter of 2006 net income and diluted earnings per share amounts were approximately $700,000 and $0.06 per share, respectively, of stock-based compensation in accordance with 123R.

Comments on the First Quarter

“CRA’s first-quarter performance marked a positive start to 2006,” said James C. Burrows, CRA International’s president and chief executive officer.  “Strong contributions from our litigation practices combined with a modest increase in business consulting, resulted in overall revenue growth in the quarter of approximately 17.5 percent.  Growth in litigation was primarily driven by our Finance and Intellectual Property practices, while the growth rate of our Pharmaceuticals practice made it the top performer in business consulting.”

“We made significant progress toward achieving our fiscal 2006 utilization goal of 78 to 80 percent,” Burrows said.  “During the quarter, utilization continued its upward sequential trend as we achieved 78 percent compared with 76 percent in the fourth quarter and 74 percent in the third quarter of fiscal 2005.  This increase is particularly noteworthy given the traditional first-quarter effect on utilization that is associated with the winter holiday season.”

Outlook and Financial Guidance

“We are in a favorable position to extend our first-quarter momentum throughout fiscal 2006,” Burrows concluded.  “Based on market conditions and our current pipeline of business, we expect to experience growth across many of our litigation and business consulting practices.  As a result, we are reaffirming our previously provided fiscal 2006 outlook and financial guidance.”

The Company anticipates revenue growth for fiscal 2006 will be in the range of 18-20 percent.  In fiscal 2006, CRA expects a 29-30 cents-per-share impact from stock-based compensation.  CRA anticipates net income for the full year 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 $47.44, 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. The net income and EPS estimates for fiscal 2006 are based on an effective tax rate for the year of approximately 42-43 percent.
