Exhibit 99.1

INDEX TO UNAUDITED PRO FORMA FINANCIAL INFORMATION OF

SIGNIFICANT EQUITY METHOD INVESTEE

CAESARS GROWTH PARTNERS, LLC

EXPLANATORY NOTE

Caesars Growth Partners, LLC (“CGP”), a Delaware limited liability company was formed as a joint venture between Caesars Acquisition Company (the “Company”), a Delaware corporation, and certain subsidiaries of Caesars Entertainment Corporation, a publicly held diversified casino entertainment and hospitality services provider. The Company’s primary asset is its membership interest in CGP, which is regarded as a significant equity method investment of the Company following a series of transactions including, among other things, the Company’s purchase of all of the voting membership units of CGP on October 21, 2013 (the “Formation Transactions”) which are more fully described in Note 1 of CGP’s Notes to Pro Forma Consolidated Condensed Financial Statements.

On September 23, 2016, Caesars Interactive Entertainment, Inc. (“CIE”), a Delaware corporation, an indirect subsidiary of CGP, completed the previously announced sale of CIE’s social and mobile games business (the “SMG Business”), pursuant to the Stock Purchase Agreement by and among CIE, Alpha Frontier Limited (the “Purchaser”), a Cayman Islands exempted company and, solely for certain limited purposes described therein, CGP and CIE Growth, LLC, a Delaware limited liability company, dated as of July 30, 2016 (the “Sale”).

CAC does not consolidate CGP into its financial statements. Instead, CAC accounts for its investment in CGP using the Hypothetical Liquidation at Book Value (“HLBV”) form of the equity method of accounting. Under the HLBV form of equity method accounting, we record our interest in the CGP entity based upon our contractual claim on CGP’s accounting balance sheet pursuant to the mandatory liquidation provisions of the CGP Operating Agreement. Under this approach, our income or loss that we recognize in any period will represent the increase or decrease in our claim on CGP’s balance sheet assuming a hypothetical liquidation at the end of that reporting period when compared with our claim on CGP’s balance sheet assuming a hypothetical liquidation at the beginning of that reporting period, after removing any contributions or distributions. CAC’s earnings from CGP for the periods presented herein were equal to our preferred return of 10.5% of capital invested by CGP.

Based upon the fact that CAC does not consolidate CGP and that CAC has recorded income on its equity method investment based upon a minimum guaranteed return, we believe that there would be no appropriate adjustments to the historical financial statements of CAC to reflect the completion of the Sale on a pro forma basis. However, given the significance of CGP to the investors of CAC, we have provided pro forma financial statements of CGP herein.

The following unaudited pro forma financial information includes the consolidated condensed balance sheet for CGP as of June 30, 2016 and the consolidated condensed statements of operations of CGP for the six months ended June 30, 2016, for the years ended December 31, 2015 and 2014, and for the period from October 22, 2013 through December 31, 2013. The unaudited pro forma consolidated condensed balance sheet illustrates the financial position of CGP as if the Sale had occurred on the balance sheet date. The unaudited pro forma consolidated condensed statements of operations illustrate the results of operations of CGP as if the Sale had occurred on October 22, 2013 and were carried forward through each of the aforementioned periods presented.

The unaudited pro forma consolidated condensed financial information is presented for illustrative purposes only and is not intended to represent or be indicative of CGP’s results of operations or financial position that would have been reported had the Sale been completed as of the dates presented, and should not be taken as a representation of CGP’s future results of operations or financial condition. The pro forma adjustments were prepared as of September 23, 2016 based on information available at the time of preparation and reflect certain assumptions that CGP believes are reasonable under the circumstances. Accordingly, the pro forma adjustments are preliminary and subject to revision and the actual amounts ultimately reported could differ from these estimates. The following unaudited pro forma consolidated condensed financial information should be read in conjunction with CGP’s historical audited consolidated financial statements and the accompanying notes thereto, which are included as an exhibit to the Company’s Annual Report on Form 10-K for the period ending December 31, 2015 pursuant to Rule 3-09 of Regulation S-X under the Securities Exchange Act of 1934, as amended.
