Forward - Looking Statement This presentation contains both historical and forward - looking statements. In this context, 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: (1) the extent to which changes to our business, operating structure, capital structure, or personnel relating to the implementation of our 2020 Vision strategi c t ransformation initiative are successful; (2) the effectiveness of our risk management and safety programs; (3) the extent to which changes in estimates of ultimate insurance losses could result in a material charge against our earnings; (4) our ability to preserve long - term client relationships; (5) our ability to attract and retain qualified personnel and senior management; (6) our success in identifying, acquiring, and integrating synergistic businesses; (7) our ability to continue to gain business despite competitive pressures; (8) the impact of costs that we cannot pass through to clients; (9) the effect of negative or unexpected tax consequences; (10) the achievement of expected benefits from our captive insurance company; (11) the impact of lo sses from accidents or other incidents at facilities in which we operate; (12) changes in energy prices and government regulations; (13) signific ant delays or reductions in appropriations for our government contracts; (14) potential failure of our joint venture partners to perform their obligations; (15) the effect of changes to federal health care reform legislation; (16) potential cyber - security breaches, information technology interruptions, data loss, or business continuity risks; (17) the effectiveness of managing operations in areas of military conflict; (18) the impact of a reduction in commercial office building occupancy; (19) the impact of deterioration in general economic conditions; (20) client - specific developments, such as financial difficulties or bankruptcy; (21) future increases in the level of our debt or in interest rates; ( 22) our ability to fund our operations and pay our debt obligations ; (23) impairment of goodwill and long - lived assets; (24) unfavorable developments in our class and representative actions and other lawsuits alleging various claims; (25) changes in immigration laws or enforcement actions or investigations under such laws; (26) the impact of liabilities associated with participation in multiemployer pension plans; ( 27) disruptions to our business through the actions of activist investors; and (28 ) weather conditions, catastrophic events and disasters, and terrorist attacks. The list of factors above is illustrative and by no means exhaustive. Additional information regarding these and other risks and uncertainties we face is contained in our Annual Report on Form 10 - K for the year ended October 31, 2015 and in other reports we file from time to time with the Securities and Exchange Commission (including all amendments to those reports ). 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. 10
