2 Cautionary Statement Regarding Forward-Looking Statements This presentation may contain forward-looking statements (including within the meaning of the Private Securities Litigation Reform Act of 1995) concerning International Game Technology PLC and its consolidated subsidiaries (the “Company”) and other matters. These statements may discuss goals, intentions, and expectations as to future plans and strategies, transactions, trends, events, dividends, results of operations, and/or financial condition and measures, or otherwise, based on current beliefs of the management of the Company as well as assumptions made by, and information currently available to, such management. Forward-looking statements may be accompanied by words such as “aim,” “anticipate,” “believe,” “plan,” “could,” “would,” “should,” “shall”, “continue,” “estimate,” “expect,” “forecast,” “future,” “guidance,” “intend,” “may,” “will,” “possible,” “potential,” “predict,” “project” or the negative or other variations of them. These forward-looking statements speak only as of the date on which such statements are made and are subject to various risks and uncertainties, many of which are outside the Company’s control. Should one or more of these risks or uncertainties materialize, or should any of the underlying assumptions prove incorrect, actual results may differ materially from those predicted in the forward-looking statements and from past results, performance, or achievements. Therefore, you should not place undue reliance on such statements. Factors that could cause actual results to differ materially from those in the forward-looking statements include (but are not limited to) the various factors and risks described in the Company’s annual report on Form 20-F for the financial year ended December 31, 2022 and other documents filed or furnished from time to time with the SEC, which are available on the SEC’s website at www.sec.gov and on the investor relations section of the Company’s website at www.IGT.com. Except as required under applicable law, the Company does not assume any obligation to update these forward-looking statements. You should carefully consider these factors and other risks and uncertainties that may affect the Company’s business, including management’s discussion and analysis of potential or actual impacts to operations and financial performance. Nothing in this presentation is intended, or is to be construed, as a profit forecast or to be interpreted to mean that the financial performance of International Game Technology PLC for the current or any future financial years will necessarily match or exceed the historical published financial performance of International Game Technology PLC, as applicable. All forward-looking statements contained in this presentation are qualified in their entirety by this cautionary statement. All subsequent written or oral forward-looking statements attributable to International Game Technology PLC, or persons acting on its behalf, are expressly qualified in their entirety by this cautionary statement. Comparability of Results All figures presented in this presentation are prepared under U.S. GAAP, unless noted otherwise. Non-GAAP Financial Measures Management supplements the reporting of financial information, determined under GAAP, with certain non-GAAP financial information. Management believes the non-GAAP information presented provides investors with additional useful information, but it is not intended to nor should it be considered in isolation or as a substitute for the related GAAP measures. Moreover, other companies may define non-GAAP measures differently, which limits the usefulness of these measures for comparisons with such other companies. The Company encourages investors to review its financial statements and publicly-filed reports in their entirety and not to rely on any single financial measure. Adjusted EBITDA represents net income (loss) (a GAAP measure) before income taxes, interest expense, net, foreign exchange gain (loss), net, other non-operating expenses (e.g., DDI / Benson Matter provision, gains/losses on extinguishment and modifications of debt, etc.), net, depreciation, impairment losses, amortization (service revenue, purchase accounting, and non-purchase accounting), restructuring expenses, stock-based compensation, litigation expense (income), and certain other non- recurring items. Other non-recurring items are infrequent in nature and are not reflective of ongoing operational activities. For the business segments, Adjusted EBITDA represents segment operating income (loss) before depreciation, amortization (service revenue, purchase accounting, and non-purchase accounting), restructuring expenses, stock-based compensation, litigation expense (income), and certain other non-recurring items. Management believes that Adjusted EBITDA is useful in providing period- to-period comparisons of the results of the Company's ongoing operational performance. Adjusted EPS represents diluted earnings per share (a GAAP measure), excluding the effects of foreign exchange, impairments, amortization from purchase accounting, discrete tax items, and other significant non-recurring adjustments that are not reflective of on-going operational activities (e.g., DDI / Benson Matter provision, gains/losses on sale of business, gains/losses on extinguishment and modifications of debt, etc.). Adjusted EPS is calculated using diluted weighted-average number of shares outstanding, including the impact of any potentially dilutive common stock equivalents that are anti-dilutive to GAAP net income (loss) per share but dilutive to Adjusted EPS. Management believes that Adjusted EPS is useful in providing period-to-period comparisons of the results of the Company's ongoing operational performance. Net debt is a non-GAAP financial measure that represents debt (a GAAP measure, calculated as long-term obligations plus short-term borrowings) minus capitalized debt issuance costs and cash and cash equivalents, including cash and cash equivalents held for sale. Cash and cash equivalents, including cash and cash equivalents classified as held for sale, are subtracted from the GAAP measure because they could be used to reduce the Company’s debt obligations. Management believes that net debt is a useful measure to monitor leverage and evaluate the balance sheet. Net debt leverage is a non-GAAP financial measure that represents the ratio of Net debt as of a particular balance sheet date to Adjusted EBITDA for the last twelve months (“LTM”) prior to such date. Management believes that Net debt leverage is a useful measure to assess IGT's financial strength and ability to incur incremental indebtedness when making key investment decisions. Free cash flow is a non-GAAP financial measure that represents cash flow from operations (a GAAP measure) less capital expenditures (a component of investing cash flows) and payments on license obligations (a component of financing cash flows). Management believes free cash flow is a useful measure of liquidity and an additional basis for assessing IGT’s ability to fund its activities, including debt service and distribution of earnings to shareholders. Adjusted free cash flow is a non-GAAP financial measure that represents free cash flow excluding the net of tax cash payments in connection with material litigation (e.g. DDI / Benson Matter). To enhance investor understanding of the Company’s performance in comparison with the prior year, the Company excluded the net of cash impacts related to the settlement of the DDI / Benson Matter. Management believes adjusted free cash flow is a useful measure of liquidity and an additional basis for assessing IGT’s performance. Constant currency is a non-GAAP financial measure that expresses the current financial data using the prior-year/period exchange rate (i.e., the exchange rate used in preparing the financial statements for the prior year). Management believes that constant currency is a useful measure to compare period-to-period results without regard to the impact of fluctuating foreign currency exchange rates. A reconciliation of the non-GAAP measures to the corresponding amounts prepared in accordance with GAAP appears in the tables in this release. The tables provide additional information as to the items and amounts that have been excluded from the adjusted measures.
