Important Information Forward-Looking Statements This presentation contains forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934, as amended. All statements, other than statements of historical fact, contained in this presentation are forward-looking statements, including, but not limited to, any statements regarding our estimates of number of gaming terminals, locations, revenues, Adjusted EBITDA, and capital expenditures. The words “predict,” “estimated,” “anticipates,” “believes,” “estimates,” “expects,” “intends,” “may,” “plans,” “projects,” “will,” “would,” “continue,” and similar expressions or the negatives thereof are intended to identify forward looking statements. 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: Accel's ability to successfully integrate its business with the business of Century and realize the full benefits of the Century acquisition; 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 fulf ill the needs of location 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 gaming terminals and by the slow growth of new gaming jurisdictions; Accel’s heavy dependency on its ability to win, maintain and renew contracts with location partners; unfavorable macroeconomic conditions or decreased discretionary spending due to other factors such as increased interest rates, increased inflation, actual or perceived instability in the U.S. and global banking systems, high fuel rates, recessions, epidemics or other public health issues, 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”). 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 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 section entitled “Risk Factors” 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 or other presentations or future quarterly reports, 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” 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 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 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, and Net Debt. Adjusted EBITDA is defined as net income plus amortization of intangible assets and route and customer acquisition costs; (gain) loss on change in fair value of contingent earnout shares; stock-based compensation expense; other expenses, net; tax effect of adjustments; depreciation and amortization of property and equipment; interest expense; emerging markets; and income tax expense. Adjusted net income is defined as net income plus amortization of intangible assets and route and customer acquisition costs; (gain) loss on change in fair value of contingent earnout shares; stock-based compensation expense; 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 9 for additional information. 2

Accel at a Glance 1. Calculated as Net Gaming Revenue in the period divided by the number of operational days. There were 217 and approximately 347 operational days for the years ended December 31, 2020 and 2021, respectively. 2. Calculated as of June 30, 2023. Net Debt is a non-GAAP financial measure that may not be comparable to other similarly titled measures of other companies. Accel does not consider this Non-GAAP measure in isolation or as an alternative to similar financial measures determined in accordance with GAAP. For more information with respect to this Non-GAAP financial measure, see page 2 “Use of Non-GAAP Financial Measures,” and for a reconciliation of this measure to its most directly comparable GAAP measure, see page 9 "Non-GAAP to GAAP Reconciliation.” 3. On November 22, 2021, the Company’s Board of Directors approved a share repurchase program of up to $200 million of shares of its Class A-1 common stock. The timing and actual number of shares repurchased will depend on a variety of factors, including price, general business and market conditions, and alternative investment opportunities. Under the repurchase program, repurchases can be made from time to time using a variety of methods, including open market purchases or privately negotiated transactions, in compliance with the rules of the United States SEC and other applicable legal requirements. The repurchase program does not obligate the Company to acquire any particular amount of shares, and the repurchase program may be suspended or discontinued at any time at the Company’s discretion. As of June 30, 2023, the Company has purchased a total of 9,709,175 shares under the plan at a cost of $100 million, of which 887,174 shares at a cost of $8 million were purchased during the quarter ended June 30, 2023.

Historical Financial Summary 7 $ in millions 1. Cost of Revenue consists of (i) taxes on net gaming revenue that is payable to the appropriate jurisdiction, (ii) licenses, permits and other fees required for the operation of gaming terminals and other equipment, (iii) location revenue share, which is governed by local governing bodies and location contracts, (iv) ATM and amusement commissions payable to locations, (v) ATM and amusement fees, and (vi) costs associated with the sale of gaming terminals. 2. Adjusted EBITDA and Adjusted Net Income are non-GAAP financial measures that may not be comparable to other similarly titled measures of other companies. Accel does not consider these non-GAAP measures in isolation or as an alternative to similar financial measures determined in accordance with GAAP. 3. (Loss) gain on change in fair value of contingent earnout shares represents a non-cash fair value adjustment at each reporting period end related to the value of these contingent shares. Upon achieving such contingency, shares of Class A-2 common stock convert to Class A-1 common stock resulting in a non-cash settlement of the obligation. 4.

Non-GAAP to GAAP Reconciliation 9 1. Amortization of intangible assets and route and customer acquisition costs consist of upfront cash payments and future cash payments to third-party sales agents to acquire the location partners that are not connected with a business acquisition, as well as the amortization of other intangible assets. We amortize the upfront cash payment over the life of the contract, including expected renewals, beginning on the date the location goes live, and recognize non-cash amortization charges with respect to such items. Future or deferred cash payments, which may occur based on terms of the underlying contract, are generally lower in the aggregate as compared to established practice of providing higher upfront payments, and are also capitalized and amortized over the remaining life of the contract. Future cash payments do not include cash costs associated with renewing customer contracts as we do not generally incur significant costs as a result of extension or renewal of an existing contract. Location contracts acquired in a business combination are recorded at fair value as part of the business combination accounting and then amortized as an intangible asset on a straight-line basis over the expected useful life of the contract of 15 years. “Amortization of intangible assets and route and customer acquisition costs” aggregates the non-cash amortization charges relating to upfront route and customer acquisition cost payments and location contracts acquired, as well as the amortization of other intangible assets. 2. Stock-based compensation consists of options, restricted stock units, and performance-based restricted stock units. 3. Loss (gain) on change in fair value of contingent earnout shares represents a non-cash fair value adjustment at each reporting period end related to the value of these contingent shares. Upon achieving such contingency, shares of Class A-2 common stock convert to Class A-1 common stock resulting in a non-cash settlement of the obligation. 4. Other expenses, net consists of (i) non-cash expenses including the remeasurement of contingent consideration liabilities, (ii) non-recurring lobbying and legal expenses related to distributed gaming expansion in current or prospective markets, and (iii) other non-recurring expenses. 5. Calculated by excluding the impact of the non-GAAP adjustments from the current period tax provision calculations. 6. Emerging markets consist of the results, on an Adjusted EBITDA basis, for non-core jurisdictions where our operations are developing. Markets are no longer considered emerging when we have installed or acquired at least 500 gaming terminals in the jurisdiction, or when 24 months have elapsed from the date we first install or acquire gaming terminals in the jurisdiction, whichever occurs first. We currently view Iowa and Pennsylvania as emerging markets. Prior to April 2023, Nebraska was considered an emerging market. Prior to July 2022, Georgia was considered an emerging market..
