AECOM Joins Russell 3000 Index

LOS ANGELES--(BUSINESS WIRE)--June 25, 2007--AECOM Technology Corporation (NYSE: ACM), a leading provider of professional technical and management support services for government and commercial clients around the world, announced today that it has been selected to be included in the broad-market Russell 3000(R) Index. This inclusion was effective immediately prior to the close of trading on Friday, June 22, 2007, when the Russell Investment Group reconstituted its comprehensive set of U.S. and global equity indexes.

Membership in the Russell 3000, which remains in place for one year, means automatic inclusion in the large-cap Russell 1000(R) Index or small-cap Russell 2000(R) as well as the appropriate growth and value style indexes. Russell determines membership for its equity indexes primarily by objective, market-capitalization rankings and style attributes.

"AECOM's inclusion in the Russell 3000 Index is a significant milestone for us following the success of our recent initial public offering," said John M. Dionisio, AECOM president and chief executive officer. AECOM completed its IPO on May 10.

The Russell 3000 serves as the U.S. component to the Russell Global Index, which Russell launched earlier this year.

Russell indexes are widely used by investment managers and institutional investors for index funds and as benchmarks for both passive and active investment strategies. An industry-leading $4 trillion in assets currently are benchmarked to them.
