CRA INTERNATIONAL REPORTS THIRD QUARTER FISCAL 2007
FINANCIAL RESULTS

Domestic and International Demand Drives 16% Revenue Growth;

Net Income Flat on Office Openings and Increased Costs

BOSTON, Mass., September 27, 2007 — CRA International, Inc. (Nasdaq: CRAI), a worldwide leader in providing economic, financial, and management consulting services, today reported financial results for its fiscal third quarter, the sixteen weeks ended August 31, 2007.

Revenue for the third quarter of fiscal 2007 increased 16.2 percent to $124.3 million from $107.0 million for the third quarter of fiscal 2006. Net income for the third quarter of fiscal 2007 was $8.6 million, or $0.72 per diluted share, compared with net income of $8.7 million, or $0.71 per diluted share, in the comparable period of fiscal 2006. Weighted average diluted shares outstanding used to calculate earnings per share in the third quarter of fiscal 2007 were 12.0 million versus 12.3 million in the third quarter of fiscal 2006.

Revenue for the first three quarters of fiscal 2007 was $295.9 million, a 12.3 percent increase from $263.6 million in the same period a year earlier. Net income for the first three quarters of fiscal 2007 was $22.3 million, a 5.7 percent increase from $21.1 million in the first three quarters of fiscal 2006. Earnings per diluted share were $1.81 in the first three quarters of fiscal 2007, compared with $1.73 in the first three quarters of fiscal 2006. Weighted average diluted shares outstanding used to calculate earnings per share in the first three quarters of fiscal 2007 were 12.3 million, versus 12.2 million in the first three quarters of fiscal 2006.

Comments on the Third Quarter

“We are pleased that third-quarter revenue increased more than 16 percent led by significant contributions in several of our U.S.-led practice areas including Competition, Transfer Pricing, and Finance,” said James C. Burrows, CRA’s president and chief executive officer. “The growth was almost entirely organic. In particular, we were pleased to see our overall Finance platform rebound from a challenging second quarter. Within our business consulting group, our Energy &

Environment and Chemicals & Petroleum practices were our top performers during the quarter, contributing to CRA’s continued strong international growth.”

“Overall hiring in the quarter was successful, as we attracted a number of industry experts in their respective fields,” Burrows said. “In conjunction with some of these hirings, we made the strategic decision to focus on internally generated growth and to invest in additional offices beyond our original plan for 2007. During the quarter, CRA opened an office in Hamburg, Germany and two new domestic offices in Tallahassee and Austin. Based on the demand for our services, we determined that these offices, which raise our operating costs in the near-term, were necessary investments in our long-term growth through expanded service offerings in our Labor and Employment, Financial Markets, and Chemicals & Petroleum practices, respectively. Our occupancy costs increased approximately $1.8 million during the quarter as compared to the third quarter of 2006, reflecting our new offices, the relocation of our London facilities, which we moved into during the quarter, and an expansion of our New York office.”

“In addition to the expenses related to these office openings and other infrastructure investments, our bottom-line was hindered by the combination of several factors,” said Burrows. “First, we incurred a $245,000 charge related to a software write-off. Second, we recorded a foreign exchange rate loss of approximately $225,000 in the quarter. And lastly, our indirect travel expenses, which essentially represent a marketing investment, increased by nearly $1 million as compared to the third quarter of 2006. As a result of these higher costs, earnings were flat compared to the same period of 2006.”

“A 1.9 percentage point increase in client reimbursable expenses as a percent of revenue from the third quarter of 2006 lowered our gross margin and operating income percentages in the third quarter of 2007,” Burrows said. “Client reimbursable expenses carry little to no mark-up for the Company.”

“Our utilization rate in the third quarter of 2007 showed a modest improvement over the sequential second quarter increasing to 76 percent despite the summer holiday season,” Burrows said. “We remain on track towards our annual goal of achieving fiscal 2007 utilization of 76 to 78 percent. We expect to be at the low end of the range based on year-to-date utilization of 76 percent.”

During the quarter, the Company bought back approximately 915,000 shares under its previously announced stock repurchase program.

Outlook and Financial Guidance

“For the fourth quarter of fiscal 2007, we expect continued strong demand for our services across our three business platforms and a return to more normalized margins,” said Burrows. “Based on this outlook and current market conditions, we continue to anticipate revenue growth in the

range of 10 to 12 percent for the year. We expect to achieve the high end of this range. Our previous guidance reflected annual net income growth in the mid to high teens percent range, and an EPS growth rate in the range of 12 to 18 percent over fiscal 2006. We expect to be at the low end of the range for net income growth and the middle part of the range for EPS growth.”

The Company’s fiscal 2007 EPS growth estimate assumes an average diluted share count of 12.1 million shares for the year (assuming no further stock repurchases in 2007) and a stock price of $48.66, which was derived from the average of the past 10 trading days. Deviations from this stock price will cause EPS to vary based on share dilution from CRA’s stock options and convertible bonds.
