Forward Looking Statements

This presentation contains both historical and forward-looking statements about ABM Industries Incorporated ("ABM") and its subsidiaries (collectively 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: The COVID-19 pandemic has had and is expected to continue having a negative effect on the global economy, and the United States economy, and it has disrupted and is expected to continue disrupting our operations and our clients' operations, which may adversely affect our business, results of operations, cash flows, and financial condition; our success depends on our ability to gain profitable business despite competitive market pressures; our business success depends on our ability to attract and retain qualified personnel and senior management and to manage labor costs; investments in and changes to our businesses, operating structure, financial reporting 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 international business involves risks different from those we face in the United States that could have an effect on our results of operations and financial condition; our use of subcontractors or joint venture partners to perform work under customer contracts exposes us to liability and financial risk; 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 may experience difficulties integrating Able Services and may not realize the growth opportunities and cost synergies that are anticipated from the Able acquisition; 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; 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; unfavorable developments in our class and representative actions and other lawsuits alleging various claims could cause us to incur substantial liabilities; 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; changes in general economic conditions, such as changes in energy prices, government regulations, or consumer preferences, could reduce the demand for facility services and, as a result, reduce our earnings and adversely affect our financial condition; future increases in the level of our borrowings or in 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, and terrorist attacks could disrupt our services; 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. We caution readers not to place undue reliance upon any such forward-looking statements, which speak only as of the date made. We undertake no obligation to publicly update any forward-looking statements, whether as a result of new information, future events, or otherwise, except as required by law.

Use of Non-GAAP Financial Information

To supplement ABM's consolidated financial information, the Company has presented income from continuing operations and income from continuing operations per diluted share as adjusted for items impacting comparability, for the fourth quarter and twelve months of fiscal years October 31, 2021 and 2020. 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 as well as ABM's operational performance. In addition, the Company has presented earnings before income from discontinued operations, net of taxes, interest, taxes, depreciation and amortization and excluding items impacting comparability (adjusted EBITDA) for the fourth quarter and twelve months of fiscal years 2021 and 2020. Adjusted EBITDA is among the indicators management uses as a basis for planning and forecasting future periods. Adjusted EBITDA margin is defined as adjusted EBITDA divided by revenue. We cannot provide a reconciliation of forward-lookingnon-GAAP adjusted EBITDA margin measures to GAAP due to the inherent difficulty in forecasting and quantifying certain amounts that are necessary for such reconciliation. The Company has also presented Free Cash Flow which is defined as net cash provided by operating activities less additions to property, plant and equipment. 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 accounting principles generally accepted in the United States of America. (See accompanying financial tables for supplemental financial data and corresponding reconciliations to certain GAAP financial measures.)
