NEW YORK, NY — June 7, 2011 — ABM Industries Incorporated (NYSE:ABM) today announced revenues for the second quarter of fiscal year 2011 of $1.06 billion, a 23.9% increase compared to second quarter of fiscal year 2010 revenues of $855.5 million. Income from continuing operations for the second quarter of fiscal year 2011 was $14.2 million, a 64.7% increase from $8.6 million in the second quarter of fiscal year 2010. Income from continuing operations per diluted share for the second quarter of fiscal year 2011 increased 63.9% to $0.26 compared to income from continuing operations per diluted share of $0.16 in the second quarter of fiscal year 2010. Income from continuing operations increased primarily as a result of a $4.7 million after-tax increase in Divisional operating profit in the second quarter of fiscal year 2011, driven by the companies acquired in 2010, and including a $2.3 million after-tax benefit from lower labor expense as a result of one less work day, partially offset by higher state unemployment insurance tax expense and fuel costs. In addition, the second quarter of fiscal year 2010 included a $2.7 million after-tax expense for a specific legal contingency. This combined benefit to the year-over-year increase in income from continuing operations in the second quarter of fiscal year 2011 was partially offset by a $1.9 million after-tax increase in interest expense compared to the year-ago quarter, primarily as a result of financing the Linc acquisition.

“The strength of our acquired businesses, combined with our continued focus on job profitability, drove second quarter results, which came in as expected,” said Henrik Slipsager, president and chief executive officer, ABM Industries Incorporated. “The quarter generated top and bottom line growth for the Company as we delivered our second consecutive quarter exceeding $1 billion in revenues and both income from continuing operations and adjusted income from continuing operations increased by double digits year-over-year. Revenue growth in the quarter was driven by the companies we acquired in 2010, which together contributed nearly $200 million. We also achieved slight organic growth, both year-over-year and sequentially. Adjusted income from continuing operations increased 26% to $15 million while adjusted income from continuing operations per diluted share increased 20% year-over-year to $0.28. The quarter also generated 43% growth in Adjusted EBITDA, which increased to $42 million compared to $29 million in the year-ago quarter.”

“As with last quarter, all four Divisions produced revenue increases year-over-year. The acquisitions of The Linc Group, L&R Parking companies and Diversco continue to increase the Company’s revenues and profitability while expanding our reach in key vertical markets. Engineering revenues increased by more than $135 million driven by The Linc Group, which also helped increase the Division’s operating profit by more than 36%. Linc Government Services, however, was impacted by the delay in passing a federal budget that postponed the start of existing projects and delayed bidding and awarding of new contracts.”

“Janitorial revenues grew through the combination of Diversco sales and strong revenue growth in the Northeast. Janitorial increased operating profit by more than 21% as a result of lower labor expense from one less work day in the quarter, which added $2.3 million after-tax, as well as the savings generated by the Division’s regional consolidation. Parking revenues increased about 37% on the strength of $43 million in sales from the L&R companies. Parking’s operating profit was down slightly as a result of a contract settlement and higher state unemployment insurance expenses in the quarter. Security revenues increased slightly with Diversco generating nearly $3 million. Security’s operating profit was essentially flat year-over-year.”

Slipsager concluded: “With the addition and successful integration of The Linc Group, Engineering continued to expand the number and scope of facility solutions we offer to reduce energy consumption and costs for clients ranging from colleges and universities to biotechnology centers and governments. Across all Divisions, we continued to win new business and expand existing businesses in key vertical markets, including financial services, health care, education, telecommunications, transportation and commercial real estate. We will continue to focus on and generate growth from the integrated facility services we deliver to our target vertical markets, leveraging our experience and expertise in meeting the distinct needs of these client sectors.”

Excluding items impacting comparability, adjusted income from continuing operations was $15.0 million, or $0.28 per diluted share, for the second quarter of fiscal year 2011. This compares to adjusted income from continuing operations of $11.9 million, or $0.23 per diluted share, in the second quarter of fiscal year 2010.

The Company’s adjusted EBITDA (earnings before interest, taxes, depreciation and amortization, and excluding discontinued operations and items impacting comparability) for the second quarter of fiscal year 2011 was $42.0 million, a 43.1% increase compared to $29.4 million in the second quarter of fiscal year 2010.

Net cash from continuing operations was $31.3 million in the second quarter of fiscal year 2011 compared to $50.0 million in the second quarter of fiscal year 2010. The decrease in net cash provided by operating activities was primarily related to the timing of both collections received from clients and payments made on vendor invoices as well as an increase in cash taxes paid as a result of the runoff in the utilization of tax assets acquired in the 2007 OneSource acquisition.

The Company reported revenues for the six months ended April 30, 2011 of $2.09 billion, a 21.1% increase compared to year-ago revenues of $1.73 billion. Income from continuing operations for the first six months of fiscal year 2011 was $22.6 million, or $0.42 per diluted share, compared to $21.5 million, or $0.41 per diluted share, for the first six months of fiscal year 2010. Adjusted income from continuing operations for the first half of fiscal year 2011 was $26.7 million, or $0.50 per diluted share, compared to $26.0 million, or $0.49 per diluted share, for the first six months of fiscal year 2010. Adjusted EBITDA for the first six months of fiscal year 2011 was $77.7 million, a 25.3% increase compared to $62.0 million for the first six months of fiscal year 2010.

The Company also announced that the Board of Directors has declared a third quarter cash dividend of $0.14 per common share payable on August 1, 2011 to stockholders of record on July 7, 2011. This will be ABM’s 181^st consecutive quarterly cash dividend.

Guidance

The Company reaffirmed its guidance and continues to estimate that income from continuing operations per diluted share for the full 2011 fiscal year will be in the range of $1.23 to $1.33 and adjusted income from continuing operations per diluted share, for the same period, of $1.43 to $1.53.

Cautionary Statement under the Private Securities Litigation Reform Act of 1995

This press release contains forward-looking statements that set forth management’s anticipated results based on management’s current plans and assumptions. Any number of factors could cause the Company’s actual results to differ materially from those anticipated. These factors include but are not limited to the following: (1) risks relating to our acquisition of Linc, including risks relating to reductions in government spending on outsourced services as well as payment delays, may adversely affect a significant portion of revenues generated by government contracts, and political and compliance risks, both domestically and abroad, may adversely impact our operations; (2) our acquisition strategy may adversely impact our results of operations; (3) intense competition can constrain our ability to gain business, as well as our profitability; (4) we are subject to volatility associated with high deductibles for certain insurable risks; (5) an increase in costs that we cannot pass on to clients could affect our profitability; (6) we provide our services pursuant to agreements which are generally cancelable by either party upon 30 to 90 days’ notice; (7) our success depends on our ability to preserve our long-term relationships with clients; (8) we incur significant accounting and other control costs that reduce profitability; (9 ) a decline in commercial office building occupancy and rental rates could affect our revenues and profitability; (10) deterioration in economic conditions in general could further reduce the demand for facility services and, as a result, reduce our earnings and adversely affect our financial condition; (11) financial difficulties or bankruptcy of one or more of our major clients could adversely affect results; (12) we are subject to risks relating to foreign currency fluctuations and foreign exchange exposure; (13) our ability to operate and pay our debt obligations depends upon our access to cash; (14) because we conduct our business through operating subsidiaries, we depend on those entities to generate the funds necessary to meet financial obligations; (15) that portion of our revenues which are generated from international operations are subject to political risks and changes in socio-economic conditions, laws and regulations, including labor, monetary and fiscal policies, which could negatively impact our ability to operate and grow our business in the international arena; (17) future declines or fluctuations in the fair value of our investments in auction rate securities that are deemed other-than-temporarily impaired could negatively impact our earnings; (18) uncertainty in the credit markets may negatively impact our costs of borrowings, our ability to collect receivables on a timely basis, and our cash flow; (19) any future increase in the level of debt or in interest rates can affect our results of operations; (20) an impairment charge could have a material adverse effect on our financial condition and results of operations; (21) we are defendants in several class and representative actions or other lawsuits alleging various claims that could cause us to incur substantial liabilities; (22) since we are an attractive employer for recent émigrés to this country and many of our jobs are filled by such, changes in immigration laws or enforcement actions or investigations under such laws could significantly adversely affect our labor force, operations and financial results as well as our reputation; (23) labor disputes could lead to loss of revenues or expense variations; (24) federal health care reform legislation may adversely affect our business and results of operations; (25) we participate in multi-employer defined benefit plans that could result in substantial liabilities being incurred; and (26) natural disasters or acts of terrorism could disrupt our services.

Additional information regarding these and other risks and uncertainties the Company faces is contained in the Company’s Annual Report on Form 10-K for the year ended October 31, 2010 and in other reports we file from time to time with the Securities and Exchange Commission.

Use of Non-GAAP Financial Information

To supplement ABM’s consolidated financial information, the Company has presented income from continuing operations, as adjusted for items impacting comparability, for the second quarter of fiscal years 2011 and 2010. The Company also presents guidance for fiscal year 2011, as adjusted. These adjustments have been made with the intent of providing financial measures that give management and investors a better understanding of the underlying operational results and trends and ABM’s marketplace performance. In addition, the Company has presented earnings before interest, taxes, depreciation and amortization and excluding discontinued operations and items impacting comparability (adjusted EBITDA) for the second quarter of fiscal years 2011 and 2010. Adjusted EBITDA is among the indicators management uses as a basis for planning and forecasting future periods. The presentation of these non-GAAP financial measures is not meant to be considered in isolation or as a substitute for financial statements prepared in accordance with generally accepted accounting principles in the United States.
