• James Lusk to Head New Shared Services Center, Will Succeed George Sundby as CFO at Year-End
• Relocating Business Units to Gain Operating Efficiencies
• Executive Headquarters to Locate in New York in 2008

SAN FRANCISCO – March 12, 2007 – ABM Industries Incorporated (NYSE: ABM), a leading facility services contractor in the United States, today announced a series of operational and leadership initiatives reinforcing the Company’s commitment to increasing shareholder value and establishing a platform supporting significant long-term growth.

Central to the initiatives is the establishment of a Shared Services center consolidating certain of the Company’s back office functions in Houston, Texas. By integrating support functions, the new Shared Services unit will increase operating efficiencies and enhance the Company’s competitive position within the industry. It also represents an extension of ABM’s ongoing strategy to invest in its technology infrastructure.

James Lusk, an executive with experience directing implementation of a Shared Services unit at other companies, is joining ABM this month as Executive Vice President. Initially, Mr. Lusk will head the Shared Services implementation and effective December 31, 2007, he will succeed George B. Sundby as Executive Vice President and Chief Financial Officer.

In addition: the Company will locate its ABM Janitorial headquarters in Houston; its other business units will be concentrated in southern California; and, in 2008, its executive headquarters will locate in New York City.

“ABM is at an exciting juncture,” said ABM President and Chief Executive Officer Henrik Slipsager. “Building on our current momentum to position the Company to best meet both market dynamics and customer-driven demands, we are re-positioning the Company for competitiveness and expansion. By consolidating back office functions in a Shared Services center in Houston, concentrating our non-Janitorial operational units in southern California, and re-tooling our management organization – including locating our executive headquarters in New York closer to many of our major customers – we will gain operating efficiencies and be able to capitalize on growth opportunities. These actions are not expected to have a material impact on previously issued earnings guidance. 

“Jim Lusk brings a wealth of experience to help us achieve these new initiatives. He is a recognized thought leader in the area of corporate Shared Services and has implemented these types of programs successfully for other companies. Given ABM’s evolution, Jim is exactly the type of executive we’ll need to succeed in the next phase of our growth – a strategic adviser to the CEO and a partner to the business unit management.

“I’d like to thank George Sundby for his many contributions to ABM. George has played a substantial role in establishing ABM as an industry leader. In particular, I’d like to recognize his efforts in enhancing our finance and control environment and leading the Company’s response to Sarbanes-Oxley. We appreciate his willingness to continue serving the Company through the end of the year and his commitment to ensure a smooth transition. Understanding that he’s not prepared to relocate at this point, we wish George much success in his future endeavors.”
