Cautionary Statement under the Private Securities Litigation Reform Act of 1995

This press release contains both historical and forward-looking statements about ABM Industries Incorporated (referred to as “ABM,” “we,” “us,” “our,” or the “Company”). We make forward-looking statements related to future expectations, estimates and projections that are uncertain, and often contain words such as “anticipate,” “believe,” “could,” “estimate,” “expect,” “forecast,” “intend,” “likely,” “may,” “outlook,” “plan,” “predict,” “should,” “target,” or other similar words or phrases. These statements are not guarantees of future performance and are subject to known and unknown risks, uncertainties, and assumptions that are difficult to predict. For us, particular uncertainties that could cause our actual results to be materially different from those expressed in our forward-looking statements include: our success depends on our ability to gain profitable business despite competitive market pressures; our results of operations can be adversely affected by labor shortages, turnover, and labor cost increases; we may not be able to attract and retain qualified personnel and senior management we need to support our business; investments in and changes to our businesses, operating structure, or personnel relating to our ELEVATE strategy, including the implementation of strategic transformations, enhanced business processes, and technology initiatives may not have the desired effects on our financial condition and results of operations; our ability to preserve long-term client relationships is essential to our continued success; our use of subcontractors or joint venture partners to perform work under customer contracts exposes us to liability and financial risk; our international business involves risks different from those we face in the United States that could negatively impact our results of operations and financial condition; decreases in commercial office space utilization due to hybrid work models and increases in office vacancy rates could adversely affect our financial condition; negative changes in general economic conditions, such as recessionary pressures, high interest rates, durable and non-durable goods pricing, changes in energy prices, or changes in consumer goods pricing, could reduce the demand for services and, as a result, reduce our revenue and earnings and adversely affect our financial condition; we may experience

breaches of, or disruptions to, our information technology systems or those of our third-party providers or clients, or other compromises of our data that could adversely affect our business; our ongoing implementation of new enterprise resource planning (“ERP”) and related boundary systems could adversely impact our ability to operate our business and report our financial results; acquisitions, divestitures, and other strategic transactions could fail to achieve financial or strategic objectives, disrupt our ongoing business, and adversely impact our results of operations; we manage our insurable risks through a combination of third-party purchased policies and self-insurance, and we retain a substantial portion of the risk associated with expected losses under these programs, which exposes us to volatility associated with those risks, including the possibility that changes in estimates to our ultimate insurance loss reserves could result in material charges against our earnings; our risk management and safety programs may not have the intended effect of reducing our liability for personal injury or property loss; unfavorable developments in our class and representative actions and other lawsuits alleging various claims could cause us to incur substantial liabilities; we are subject to extensive legal and regulatory requirements, which could limit our profitability by increasing the costs of legal and regulatory compliance; a significant number of our employees are covered by collective bargaining agreements that could expose us to potential liabilities in relation to our participation in multiemployer pension plans, requirements to make contributions to other benefit plans, and the potential for strikes, work slowdowns or similar activities, and union organizing drives; our business may be materially affected by changes to fiscal and tax policies; negative or unexpected tax consequences could adversely affect our results of operations; future increases in the level of our borrowings and interest rates could affect our results of operations; impairment of goodwill and long-lived assets could have a material adverse effect on our financial condition and results of operations; if we fail to maintain proper and effective internal control over financial reporting in the future, our ability to produce accurate and timely financial statements could be negatively impacted, which could harm our operating results and investor perceptions of our Company and as a result may have a material adverse effect on the value of our common stock; our business may be negatively impacted by adverse weather conditions; catastrophic events, disasters, pandemics, and terrorist attacks could disrupt our services; and actions of activist investors could disrupt our business. For additional information on these and other risks and uncertainties we face, see ABM’s risk factors, as they may be amended from time to time, set forth in our filings with the Securities and Exchange Commission, including our most recent Annual Report on Form 10-K and subsequent filings. We urge readers to consider these risks and uncertainties in evaluating our forward-looking statements.
