(“Century”) on the historical financial statements of Accel Entertainment, Inc. (“Accel”). On June 1, 2022, Accel completed the acquisition of all outstanding equity interests of Century in exchange for $158.7 million in cash, which includes the repayment of $113.2 million of Century’s debt, and $5.6 million in shares, representing 515,622 of Accel’s shares at a price of $10.83 per share, subject to adjustments related to cash and working capital at closing (the “Acquisition”). The unaudited pro forma condensed combined statement of operations for the year ended December 31, 2021 combines the historical audited consolidated statement of operations of Accel for the year ended December 31, 2021 and the historical unaudited statement of operations of Century for the year ended December 31, 2021, on a pro forma basis as if the business combination had been consummated on January 1, 2021. The unaudited pro forma condensed combined statement of operations for the three months ended March 31, 2022 combines the historical unaudited condensed consolidated statement of operations of Accel for the three months ended March 31, 2022 and the historical unaudited condensed statement of operations of Century for the three months ended March 31, 2022, on a pro forma basis as if the business combination had been consummated on January 1, 2021. The unaudited condensed consolidated balance sheet dated June 30, 2022 included in the Form 10-Q filed with the SEC on August 9, 2022 reflects the impact of the Acquisition, and as such, Article 11 of Regulation S-X does not require the presentation of a pro forma balance sheet. The unaudited pro forma condensed combined statement of operations give effect to the following: • The acquisition of Century and the impact of preliminary purchase accounting for the acquired assets and assumed liabilities; • The reclassification of certain Century historical financial information to conform to Accel presentation; • The impact of additional financing and the repayment of Century’s debt resulting from the Acquisition; • The related income tax effects of the pro forma adjustments. The unaudited pro forma condensed combined financial information was derived from and should be read in conjunction with the following historical financial statements and the accompanying notes: • The (a) historical audited consolidated financial statements of Accel as of and for the year ended December 31, 2021, included in Accel’s Annual Report on Form 10-K filed with the SEC on March 10, 2022 and incorporated by reference and (b) historical unaudited condensed consolidated statement of operations of Accel as of and for the three months ended March 31, 2022 included in Accel’s Quarterly Report on Form 10-Q filed with the SEC on May 4, 2022 and incorporated by reference; • The (a) historical audited financial statements of Century as of and for the fiscal year ended June 30, 2021 included elsewhere in this Form 8-K/A filed with the SEC on August 15, 2022 and (b) historical unaudited condensed financial statements of Century as of and for the nine months ended March 31, 2022 included elsewhere in this Form 8-K/A filed with the SEC on August 15, 2022 and incorporated herein by reference. Unaudited six month information ending June 30, 2021 from the historical audited financial statements of Century for the year ended June 30, 2021 is combined with six month information ending December 31, 2021 from the historical unaudited interim financial statements of Century to present a twelve month period. Unaudited three month information ending March 31, 2022 from the historical unaudited interim financial statements of Century is presented as a three month period. Additional information about the basis of presentation of this information is provided in Note 2 hereto. The unaudited pro forma condensed combined financial information has been prepared to illustrate the effect of the Acquisition as if it had been consummated on January 1, 2021. It has been prepared for informational purposes

only and is subject to a number of uncertainties and assumptions as described in the accompanying notes. The historical consolidated statement of operations has been adjusted in the unaudited pro forma condensed combined financial information to give effect to pro forma events described above. The unaudited pro forma adjustments to the historical consolidated statement of operations are based on currently available information, and in many cases are based on estimates and management’s preliminary valuation of the fair value of tangible and intangible assets acquired and liabilities assumed. The assumptions underlying the pro forma adjustments are described in the accompanying notes to these unaudited pro forma statements of operations. Management believes such assumptions are reasonable under the circumstances and reflect the best currently available estimates and judgments. The actual purchase accounting assessment may vary based on the final analysis of the valuation of assets acquired and liabilities assumed, particularly with regards to finite-lived intangible assets and deferred tax assets and liabilities, which could be material. Accel will finalize the accounting for the Acquisition as soon as practicable within the measurement period in accordance with ASC 805, but in no event later than one year from the Acquisition date. The unaudited pro forma condensed combined statement of operations may not be indicative of Accel’s future performance and do not necessarily reflect what Accel’s results of operations would have been had these transactions occurred at the beginning of the period presented. Further, the unaudited pro forma condensed combined statement of operations does not purport to project the future operating results or financial position of Accel following the completion of the Acquisition. Additionally, the unaudited pro forma statements of operations do not reflect any potential revenue enhancements, anticipated synergies, operating efficiencies, or cost savings that may be achieved related to these transactions, nor do they reflect any potential costs or expenditures that may be required to achieve any possible synergies.

Note 2. Basis of the Pro Forma Presentation The unaudited pro forma condensed combined financial information and related notes are prepared in accordance with Article 11 of Regulation S-X and are intended to show how the transaction might have affected the historical financial statements. The accompanying unaudited pro forma condensed combined statements of operations for the year ended December 31, 2021 and three months ended March 31, 2022 give pro forma effect to the acquisition as if it had been completed on January 1, 2021. The unaudited pro forma condensed combined statements of operations are based on the historical consolidated statements of operations of Accel and Century after giving effect to the Acquisition using the acquisition method of accounting, as well as certain reclassification and pro forma adjustments. Under this method of accounting, which is in accordance with U.S. GAAP, Accel is the accounting acquirer of Century and the purchase price for Century is allocated to the underlying assets acquired and liabilities assumed based on their respective fair values, with any excess purchase price allocated to goodwill. The preliminary purchase price allocation is reflected in the unaudited condensed financial statements of Century as of and for the three months ended June 30, 2022 included in Accel’s Quarterly Report on Form 10-Q filed with the SEC on August 9, 2022. The unaudited pro forma condensed combined financial information was derived from and should be read in conjunction with the following historical financial statements and the accompanying notes: • The (a) historical audited consolidated financial statements of Accel as of and for the year ended December 31, 2021, included in Accel’s Annual Report on Form 10-K filed with the SEC on March 10, 2022 and incorporated by reference and (b) historical unaudited condensed consolidated statement of operations of Accel as of and for the three months ended March 31, 2022 included in Accel’s Quarterly Report on Form 10-Q filed with the SEC on May 4, 2022 and incorporated by reference; • The (a) historical audited financial statements of Century as of and for the fiscal year ended June 30, 2021 included elsewhere in this Form 8-K/A filed with the SEC on August 15, 2022 and (b) historical unaudited condensed financial statements of Century as of and for the nine months ended March 31, 2022 included elsewhere in this Form 8-K/A filed with the SEC on August 15, 2022 and incorporated herein by reference. Unaudited six month information ending June 30, 2021 from the historical audited financial statements of Century for the year ended June 30, 2021 is combined with six month information ending December 31, 2021 from the historical unaudited interim financial statements of Century to present a twelve month period. Unaudited three month information ending March 31, 2022 from the historical unaudited interim financial statements of Century is presented as a three month period. Both Accel’s and Century’s historical consolidated statements of operations were prepared in accordance with U.S. GAAP and are presented in U.S. dollars. In addition, Century’s historical unaudited consolidated statement of operations have been adjusted for certain reclassifications. Reclassifications have been made to Century’s historical financial information to conform to Accel’s financial statement presentation. Such reclassifications had no effect on Century’s previously reported financial results. As part of the integration process, Accel will continue to review Century’s accounting policies, including any differences between Accel’s and Century’s historical presentation of the statements of operations under U.S. GAAP. Management may identify differences between the accounting policies of the two companies that, when conformed, could have a material impact on Accel’s

condensed combined statement of operations. See “Note 3 – Accounting Policies and Reclassification of Century Historical Statement of Operations” herein for additional information on the reclassifications. The pro forma adjustments presented in these unaudited pro forma condensed combined statements of operations represent management’s estimates based on information available as of the date of this Form 8-K/A and are subject to revision as further information is obtained. Accordingly, the pro forma adjustments for the business combination are preliminary and subject to further adjustment as additional information becomes available and the various analyses and other valuations are performed. Any adjustments may have a significant effect on total assets, total liabilities, total equity, operating expenses, and depreciation and amortization expenses and such results may be significant.
