All statements, other than statements of historical fact, contained in this presentation are forward-looking statements, including, but not limited to, statements regarding our strategy, prospects, plans, objectives, future operations, future revenue and earnings, projected margins and expenses, markets for our services, potential acquisitions or strategic alliances, financial position, and liquidity and anticipated cash needs and availability. The words “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would,” and similar expressions or the negatives thereof are intended to identify forward-looking statements. However, not all forward-looking statements contain these identifying words. These forward-looking statements represent our current reasonable expectations and involve known and unknown risks, uncertainties and other factors that may cause our actual results, performance and achievements, or industry results, to be materially different from any future results, performance or achievements expressed or implied by such forward-looking statements. We cannot guarantee the accuracy of the forward-looking statements, and you should be aware that results and events could differ materially and adversely from those contained in the forward-looking statements due to a number of factors including, but not limited to: the existing and potential future adverse impact of the COVID-19 pandemic on Accel Entertainment, Inc.’s (the “Company” or “Accel”) business, operations and financial condition, including as a result the suspensions of all video gaming terminal operations by the Illinois Gaming Board between March 16, 2020 and June 30, 2020 and between November 19, 2020 and January 23, 2021, which suspensions could be reinstated; Accel’s ability to operate in existing markets or expand into new jurisdictions; Accel’s ability to manage its growth effectively; Accel’s ability to offer new and innovative products and services that fulfill the needs of licensed establishment partners and create strong and sustained player appeal; Accel’s dependence on relationships with key manufacturers, developers and third parties to obtain gaming terminals, amusement machines, and related supplies, programs, and technologies for its business on acceptable terms; the negative impact on Accel’s future results of operations by the slow growth in demand for VGTs and by the slow growth of new gaming jurisdictions; Accel’s heavy dependency on its ability to win, maintain and renew contracts with licensed establishment partners; unfavorable economic conditions or decreased discretionary spending due to other factors such as epidemics or other public health issues (including COVID-19), terrorist activity or threat thereof, civil unrest or other economic or political uncertainties, that could adversely affect Accel’s business, results of operations, cash flows and financial conditions and other risks and uncertainties indicated from time to time in documents filed or to be filed with the Securities and Exchange Commission ("SEC"). Anticipated effects or benefits from the contemplated transaction may not ultimately occur, including expected revenues; effective integration of Century’s operations, establishments and terminals with our own; integration of new technology to our own portfolio; and, integration of player rewards programs into our own system or expansion of those rewards programs in other US markets. We cannot guarantee the accuracy of the forward-looking statements, and you should be aware that results and events could differ materially and adversely from those contained in the forward-looking statements due to a number of factors including, but not limited to the existing and potential future adverse impact of the COVID-19 pandemic on Century’s business, operations and financial condition, including as a result of any suspension of gaming operations in Nevada or Montana; our ability to expand effectively into Nevada and Montana; our ability to manage growth effectively; our ability to offer new and innovative products and services that fulfill the needs of Century’s establishment partners and create strong and sustained player appeal; Century’s dependence on relationships with key manufacturers, developers and third parties; the negative impact on Century’s future results of operations by the slow growth in demand for gaming terminals and by slow growth of gaming in Nevada and Montana; Century’s heavy dependency on its ability to win, maintain and renew contracts with licensed establishment partners; unfavorable economic conditions or decreased discretionary spending due to other factors such as epidemics or other public health issues (including COVID-19), terrorist activity or threat thereof, civil unrest or other economic or political uncertainties, that could adversely affect Accel’s or Century’s business, results of operations, cash flows and financial conditions and other risks and uncertainties. Accordingly, forward-looking statements, including any projections or analysis, should not be viewed as factual and should not be relied upon as an accurate prediction of future results. The forward-looking statements contained in this presentation are based on our current expectations and beliefs concerning future developments and their potential effects on the Accel. These forward-looking statements involve a number of risks, uncertainties (some of which are beyond our control), or other assumptions that may cause actual results or performance to be materially different from those expressed or implied by these forward-looking statements. These risks and uncertainties include, but are not limited to, those factors described in the sections entitled “Risk Factors” in the Quarterly Reports on Form 10-Q and in the Annual Report on Form 10-K filed by Accel with the SEC, as well as Accel’s other filings with the SEC. Except as required by law, we do not undertake publicly to update or revise these statements, even if experience or future changes make it clear that any projected results expressed in this presentation or future quarterly reports, press releases or company statements will not be realized. In addition, the inclusion of any statement in this presentation does not constitute an admission by us that the events or circumstances described in such statement are material. We qualify all of our forward-looking statements by these cautionary statements. In addition, the industry in which we operate is subject to a high degree of uncertainty and risk due to a variety of factors including those described in the section entitled “Risk Factors.” These and other factors could cause our results to differ materially from those expressed in this presentation. Industry and Market Data Unless otherwise indicated, information contained in this presentation concerning our industry and the markets in which we operate, including our general expectations and market position, market opportunity, and market size, is based on information from various sources, on assumptions that we have made that are based on those data and other similar sources, and on our knowledge of the markets for our services. This information includes a number of assumptions and limitations, and you are cautioned not to give undue weight to such information. In addition, projections, assumptions, and estimates of our future performance and the future performance of the industry in which we operate are necessarily subject to a high degree of uncertainty and risk due to a variety of factors, including those described in the Quarterly Reports on Form 10-Q and in the Annual Report on Form 10-K filed by Accel with the SEC, as well as Accel’s other filings with the SEC. These and other factors could cause results to differ materially from those expressed in the estimates made by third parties and by us. Use of Non-GAAP Financial Measures This presentation includes non-GAAP financial measures, including Adjusted EBITDA, Adjusted net income (loss), and Net Debt. Adjusted EBITDA is defined as net income plus amortization of route and customer acquisition costs and location contracts acquired; change in fair value of contingent earnout shares; change in fair value of warrants; stock-based compensation expense; other expenses, net; tax effect of adjustments; depreciation and amortization of property and equipment; emerging markets; interest expense; provision for income taxes; and loss on debt extinguishment. Adjusted net income is defined as net income (loss) plus amortization of route and customer acquisition costs and location contracts acquired; stock-based compensation expense; loss (gain) on change in fair value of contingent earnout shares; (gain) loss on change in fair value of warrants; other expenses, net; and tax effect of adjustments. Net Debt is defined as Debt, net of current maturities plus Current maturities of debt less Cash and cash equivalents. Management believes that these non-GAAP measures of financial results enhance the understanding of Accel’s underlying drivers of profitability and trends in Accel’s business and facilitate company-to-company and period-to period comparisons, because these non-GAAP financial measures exclude the effects of certain non-cash items or represent certain nonrecurring items that are unrelated to core performance. Management of Accel also believes that these non-GAAP financial measures are used by investors, analysts and other interested parties as measures of financial performance and to evaluate Accel’s ability to fund capital expenditures, service debt obligations and meet working capital requirements. See the slide entitled “Non-GAAP to GAAP Reconciliation” on page 11 for additional information. 2

Hold-per-day (HPD) is calculated by dividing the difference between cash deposited in all VGTs at each licensed establishment and tickets issued to players at each licensed establishment by the number of locations in operation each day during the period being measured. Then divide the calculated amount by the number of operating days in such period. Hold per day for the three months ended March 31, 2020, December 31, 2020, and March 31, 2021 is computed based on 76, 50, and 72, respectively, eligible gaming days (excludes 15, 42, and 18, respectively, non-gaming days due to the IGB mandated COVID-19 shutdowns). 2.
