News Release Details

BOSTON--(BUSINESS WIRE)--June 16, 2005--CRA International, Inc. (NASDAQ: CRAI), a globally known leader in providing economic, financial, and management consulting services, today announced that its U.K. subsidiary has completed the acquisition of Economics of Competition & Litigation Limited (formerly known as Lexecon Ltd). As part of the transaction, approximately 30 former Lexecon Ltd consultants and academic experts have joined CRA.

Under the terms of the agreement, CRA acquired the former Lexecon Ltd business for a purchase price of GBP 8.4 million (approximately US$15.2 million), consisting of GBP 6.3 million (US$11.4 million) in cash and GBP 2.1 million (US$3.8 million) in loan notes to be exchanged for restricted shares of CRA stock. Additional purchase consideration may be payable if specific performance targets are met. The firm recorded trailing-twelve-months revenues of approximately GBP 7.4 million (US$13.5 million). CRA expects the acquisition to be accretive.

The firm is a leading provider of competition economics in Europe. It has been involved in many of the high-profile cases of the past several years, including Airtours, GE/Honeywell, Tetra/Sidel, Microsoft and Oracle/Peoplesoft. With its London headquarters and an established Brussels office, the firm is currently advising on major matters before the European Commission, the Court of First Instance, and the competition and regulatory authorities of several Member States, as well as on major cases in South Africa, Hong Kong, and Singapore, among others.

The former Lexecon Ltd business also has an expanding commercial litigation practice, a further growth opportunity for CRA International. CRA's capability in this area was enhanced by its April 2005 acquisition of Lee & Allen, a leading U.K.-based forensic accounting and financial dispute resolution firm.

"This acquisition provides CRA with a stronger foundation for growth in the expanding economic consulting market in Europe, and provides additional expansion opportunities in South Africa," said James C. Burrows, President and CEO of CRA International. "As a result of this acquisition and our recent addition of Lee & Allen, CRA now has the largest independent litigation support practice in Europe. We look forward to capitalizing on the more commanding global presence we now have in litigation support and competition economics."
