SAN FRANCISCO — March 13, 2006 — ABM Industries Incorporated (NYSE:ABM), announced today that for the first quarter ended January 31, 2006, the Company now expects income from continuing operations will be approximately $0.07 per diluted share. For full-year 2006, the Company anticipates income from continuing operations will be in the range of $0.85 to $0.95 per diluted share.

The revised outlook for 2006 reflects lower than expected first quarter results, anticipated future losses from a security service business acquired in 2004 and second quarter 2006 professional fees associated with an ongoing independent investigation of accounting errors and related controls in the security segment conducted under the supervision of the Audit Committee of ABM’s Board of Directors. 

“With the exception of Security, our operating performance remains solid and so far this fiscal year we’ve seen revenue growth in our four largest operating segments,” said Henrik Slipsager, ABM’s president and chief executive officer. “Our new guidance largely reflects a lower outlook in the Security service segment in 2006 and the second quarter 2006 costs associated with the Audit Committee’s ongoing investigation of the recent accounting errors and related controls in the security segment. 

“We’re also reviewing programs to improve our financial control environment and help reduce the Company’s audit and certification costs through centralized processes,” Slipsager concluded.
