CRA INTERNATIONAL REPORTS SECOND-QUARTER

FISCAL 2005 FINANCIAL RESULTS

Revenue Increases Nearly 48 Percent on Organic Growth and Acquisitions;
Net Income Grows 36 Percent, as Consultant Utilization Reaches 81 Percent

BOSTON, June 9, 2005 — CRA International, Inc. (Nasdaq: CRAI), an internationally known leader in providing economic, financial, and management consulting services, today reported financial results for the second quarter of fiscal 2005, ended May 13, 2005.

Second-quarter fiscal 2005 revenue increased nearly 48 percent to $67.4 million from $45.7 million for the second quarter of fiscal 2004.  Net income for the second quarter of fiscal 2005 increased approximately 36 percent to $5.5 million, or $0.49 per diluted share, from $4.0 million, or $0.38 per diluted share, in the second quarter of fiscal 2004.  CRA International’s effective tax rate for the second quarter of fiscal 2005 was 44 percent compared with 43 percent in the second quarter of fiscal 2004.  Weighted average diluted shares outstanding used to calculate earnings per share in the second quarter of fiscal 2005 were 11.2 million, versus 10.7 million in the second quarter of fiscal 2004.

Revenue for the first two quarters of fiscal 2005 was $129.2 million, a 53 percent increase from $84.2 million in the same period a year earlier.  Net income for the first two quarters of fiscal 2005 was $10.1 million, a 53 percent increase from $6.6 million in the first two quarters of fiscal 2004.  Earnings per diluted share were $0.92 in the first two quarters of fiscal 2005 compared with $0.62 in the first two quarters of fiscal 2004.  Weighted average diluted shares outstanding used to calculate earnings per share in the first two quarters of fiscal 2005 were 11.0 million, versus 10.7 million in the first two quarters of fiscal 2004.

Comments on the Second Quarter

James C. Burrows, CRA International’s president and CEO, said, “Continued strength in underlying demand within our end markets, as well as contributions from our fiscal 2004 acquisitions, drove year-over-year revenue growth in nearly all of our litigation and business consulting practices in the second quarter, particularly among our largest practices.  During the quarter, four of CRA’s five largest practices recorded substantial growth, and the fifth maintained its revenue rate, from the prior-year period.  Reflecting a significant improvement in the profitability of our foreign offices and our tax planning efforts, our effective tax rate was 44 percent in the second quarter, compared with 47 percent in the first quarter.”

“During the quarter, we took additional steps to strengthen our London operations as a foundation for further penetration into Europe and other international markets.  The acquisition of Lee & Allen added 43 consultants to our roster and enhanced our ability to capitalize on consulting opportunities in Europe, Africa, and Asia.  As this acquisition occurred only 2½ weeks before our quarter-end, it did not have a material impact on our Q2 results, but it will contribute to revenues and earnings in the second half of the year.  Our expected completion of the acquisition of the former Lexecon Ltd consulting firm will reinforce our European initiative,” continued Burrows.

“CRA enjoyed strong performance from an operational perspective in the second quarter as well, with robust demand driving utilization of 81 percent, consistent with the second quarter of 2004.  Maintaining year-over-year utilization in the second quarter is a significant accomplishment considering our high level of acquisition activity in the past year and the related integration requirements.  This increase in utilization was enabled by strong organic growth in the neighborhood of 20 percent.  As a result of our utilization level and revenue growth, CRA achieved operating margins of 15.4 percent in the second quarter, in line with our long-term target of 15 percent or better,” said Burrows.

Outlook and Financial Guidance

Burrows concluded, “We believe the fundamental business trends in the markets we serve will provide sustainable demand for our consulting services for the remainder of fiscal 2005 and for the foreseeable future.  As a result, we now are raising our 2005 guidance for revenue and earnings per share growth to the 35-40 percent range from 30-35 percent, and for income from operations and net income to the 40-45 percent range from 30-35 percent.  In preparing our EPS guidance, in order to estimate potential share dilution, we utilized a stock price of approximately $55.50, which was the average closing price of the 10 trading days through June 8.  Deviations from this price will cause our earnings per share to vary based on the amount of share dilution from our stock options and convertible bonds.  Our revised guidance does not include the anticipated acquisition of the former Lexecon Ltd business.”
