ABM INDUSTRIES ANNOUNCES FIRST QUARTER FISCAL 2007 FINANCIAL RESULTS

Company Achieves First Quarter Record Net Income of $8.7 Million
Up 118.1% on Record Sales of $703.5 Million

SAN FRANCISCO, CA — March 5, 2007 — ABM Industries Incorporated (NYSE:ABM), a leading facility services contractor in the United States, today reported net income for the first quarter of fiscal 2007 of $8.7 million ($0.18 per diluted share), up 118.1%, compared to $4.0 million ($0.08 per diluted share) for the prior year first quarter. Sales and other income for the first quarter of fiscal 2007 were $703.5 million, up 5.5% from $666.6 million in the first quarter of fiscal 2006.

Net income of $8.7 million for first quarter of 2007 included a net after-tax benefit of approximately $0.5 million ($0.01 per diluted share) comprised of a $4.2 million ($2.5 million after-tax) benefit from the reduction of the Company’s self insurance reserves related to prior years’ insurance claims that was partially offset by $2.0 million ($1.2 million after-tax) of additional share-based compensation expense due to the acceleration of price vested employee stock options and a $1.4 million ($0.8 million after-tax) litigation-related contingent loss provision. The first quarter of 2006 included an additional $3.0 million ($1.8 million after-tax) of professional fees related to the Sarbanes-Oxley internal controls certification requirement compared to the first quarter of fiscal 2007.

“ABM’s strong first quarter performance reflects the demand for our high quality building services and is evidence of the hard work and dedication of our entire organization,” commented Henrik Slipsager, ABM’s president and chief executive officer. “All business segments showed top-line growth due to a combination of sales from new customers and expanded services for existing customers, and operating profits improved in our janitorial, parking, security and lighting operations. Janitorial had an outstanding quarter as they continued to experience growth in both tag work and owner-occupied sales. Our Parking business benefited from higher lease and fixed allowance revenues and, as anticipated, our Lighting business was driven by the backlog for special projects.”

Mr. Slipsager continued, “We ended the first quarter with approximately $91 million in cash and cash equivalents, approximately $324 million in working capital and no debt. Based on our strong balance sheet and sound strategy, we believe that we are well positioned to continue to expand our existing lines of business in fiscal 2007 through organic growth and acquisitions. We continue to focus on expanding our new business and are committed to using our financial and management resources to further our position as a leading national service provider.”

Guidance
The Company expects net income for the second quarter to be $0.28 to $0.32 per diluted share, including a pre-tax gain of approximately $5 million on the sale of one of the Company’s off-airport parking leases and a pre-tax expense of $1.9 million from the vesting of additional price-vested employee stock options. The Company is increasing its fiscal 2007 guidance of net income to $1.04 to $1.08 per diluted share on a GAAP-basis and in the range of $1.12 to $1.16 per diluted share on a non-GAAP basis, the difference being the additional expenses for certain costs associated with the Company’s implementation of new IT systems.

A reconciliation of non-GAAP operating earnings guidance for Q1 and the remainder of the fiscal year ending October 31, 2007 is included in the tables below titled: “Reconciliation of Consolidated GAAP to Consolidated Non-GAAP.”

References by the Company to non-GAAP income and non-GAAP earnings per share refer to net income or earnings per share excluding the effect of certain costs associated with the Company’s investment in information technology systems. Non-GAAP net income (which is the basis for non-GAAP earnings per share) gives an indication of ABM’s baseline performance before this cost, which the Company considers to be outside the Company’s ongoing operating results. The Company believes these non-GAAP measures will aid investors’ overall understanding of the Company’s results by providing a higher degree of transparency for certain expenses, through providing a level of disclosure that will help investors understand how the Company plans and measures its own business. However, the presentation of non-GAAP measures is not meant to be considered in isolation or as a substitute for financial information provided in accordance with GAAP.
