ELDORADO RESORTS REPORTS FIRST QUARTER 2020 RESULTS

Reno, Nevada (May 11, 2020) – Eldorado Resorts, Inc. (NASDAQ: ERI) (“Eldorado,” “ERI,” or “the Company”) today reported operating results for the first quarter ended March 31, 2020.

First Quarter 2020 and Recent Highlights:

Tom Reeg, Chief Executive Officer of Eldorado Resorts, commented, “Our first quarter operating performance through the end of February 2020 represented a very strong start to the year. For the first two months of 2020, revenues were up 6.6% and adjusted EBITDA was up 24.7%, driving strong margin growth of 390 basis points year over year. We were encouraged by the strength of the consumer and the pace of revenue growth for this two-month period. However, the strength in January and February was offset by COVID-19 related weakness due to the mandated closure of all our properties by March 18, 2020. As a result, Eldorado generated first quarter same-store net revenues of $473.1 million and EBITDA of $102.5 million, down 17.5% and 33.0% year over year, respectively.

“Our primary focus since the mandated closure of our properties has been the safety and well-being of our team members and guests. We responded quickly to reduce costs and preserve liquidity following the closures and ended the first quarter of 2020 with over $670 million of cash on the balance sheet after drawing $465 million on our revolver in March. Our full-time team members received four weeks of pay after operations were suspended and we will continue to pay team member health care benefits through June 30, 2020. Compensation for the executive team has been reduced as well.

“We remain actively engaged in satisfying the remaining steps to complete the Caesars transaction. Our teams also remain focused on the integration process and we remain excited about the long-term opportunity to create value for stakeholders of both companies.”

Balance Sheet and Liquidity

As of March 31, 2020, Eldorado had $3.0 billion of debt outstanding. Total cash and cash equivalents were $671.7 million, excluding restricted cash.

“We have a very strong liquidity position which will allow us to weather the short-term weakness due to COVID-19 mandated closure of our properties. In addition, we continue to expect the announced $230 million sale of our Kansas City and Vicksburg properties to Twin River to close in the current quarter following receipt of customary regulatory approvals,” said Bret Yunker, Chief Financial Officer.

Summary of 2020 First Quarter Regional Results

Results for Presque Isle Downs and Nemacolin are excluded from results of operations for the first quarter of 2019. Results for Mountaineer, Cape Girardeau and Caruthersville have also been excluded from results of operations for the first quarter of 2019 as they were divested to Century Casinos in December 2019. This presentation is intended to provide insights on same-store results and does not conform to GAAP or the Securities and Exchange Commission rules for pro forma presentation; however, we believe that this additional financial information will be helpful to investors in comparing current results with results of prior periods.

Reconciliation of GAAP Measures to Non-GAAP Measures

Adjusted EBITDA (defined below), a non-GAAP financial measure, has been presented as a supplemental disclosure because it is a widely used measure of performance and basis for valuation of companies in our industry and we believe that this non-GAAP supplemental information will be helpful in understanding the Company’s ongoing operating results. Management has historically used Adjusted EBITDA when evaluating operating performance because we believe that the inclusion or exclusion of certain recurring and non-recurring items is necessary to provide a full understanding of our core operating results and as a means to evaluate period-to-period results. Adjusted EBITDA represents operating income (loss) before depreciation and amortization, stock-based compensation, impairment charges, transaction expenses, severance expense, selling costs associated with the divestitures of properties, equity in income (loss) of unconsolidated affiliates, (gain) loss on the sale or disposal of property and equipment, and (gain) loss related to divestitures. Adjusted EBITDA also excludes the expense associated with our Master Lease with GLPI as the transaction was accounted for as a financing obligation and the associated expense is included in interest expense. Adjusted EBITDA is not a measure of performance or liquidity calculated in accordance with accounting principles generally accepted in the United States (“US GAAP”), is unaudited and should not be considered an alternative to, or more meaningful than, net income (loss) as an indicator of our operating performance. Uses of cash flows that are not reflected in Adjusted EBITDA include capital expenditures, interest payments, income taxes, debt principal repayments, payments under our Master Lease and certain regulatory gaming assessments, which can be significant. As a result, Adjusted EBITDA should not be considered as a measure of our liquidity. Other companies that provide EBITDA information may calculate EBITDA differently than we do. The definition of Adjusted EBITDA may not be the same as the definitions used in any of our debt agreements.
