CRA INTERNATIONAL ANNOUNCES PRELIMINARY
SECOND-QUARTER FISCAL 2007 FINANCIAL RESULTS

Company Lowers Guidance for Fiscal 2007;
 Second-Quarter Conference Call to be Webcast on June 7, 2007

BOSTON, May 31, 2007 – CRA International (NASDAQ: CRAI), a worldwide leader in providing economic, financial, and management consulting services, today announced preliminary financial results for its second quarter ended May 11, 2007. 

Based on preliminary results, CRA expects to report revenue of approximately $88 million for the second quarter of fiscal 2007, compared with $84.0 million in the second quarter of fiscal 2006.  Net income for the second quarter of fiscal 2007 is expected to be approximately $6.7 million, or $0.53 per share, including a net tax benefit of approximately $1.4 million, or $0.11 per share, related to the conclusion of an advanced pricing agreement the Company entered into with the IRS offset by the effect of trapped losses in several locations.  This compares with net income of $6.7 million, or $0.55 per share, in the second quarter of fiscal 2006.

“Our second-quarter performance was below expectations due to a combination of factors,” said James C. Burrows, CRA International’s president and chief executive officer.  “Litigation-related revenues were affected by the settlement of certain large litigation projects, a slowdown in others, and delays in the initiation of new litigation cases during the quarter.  We anticipate stronger top-line performance in this sector during the second half of fiscal 2007.  The year-over-year decline in profitability for the second quarter was primarily attributable to lower-than-expected revenues, and to a lesser extent, certain costs incurred that represent investments in facilities and staff.”

Based on its second-quarter performance, the Company is revising its fiscal 2007 guidance.  For the year, the Company anticipates revenue growth in the 10 to 12 percent range, annual net income growth in the mid to high teens percent range, and EPS growth rate is now expected to be 12 to 17 percent over fiscal 2006.

The Company’s revised fiscal 2007 EPS estimate assumes an average diluted share count of 12.5 million shares for the year and a stock price of $52.51, which was derived from the average of the past 10 trading days ended May 30.  Deviations from this stock price will cause EPS to vary based on share dilution from CRA’s stock options and convertible bonds.
