ELDORADO RESORTS REPORTS SECOND QUARTER NET REVENUE OF $456.8 MILLION,

OPERATING INCOME OF $77.4 MILLION AND RECORD ADJUSTED EBITDA OF $118.0 MILLION

Reno, Nev. (August 2, 2018) – Eldorado Resorts, Inc. (NASDAQ: ERI) (“Eldorado,” “ERI,” or “the Company”) today reported operating results for the second quarter ended June 30, 2018. Separately, Eldorado also announced that at a meeting earlier today, the Illinois Gaming Board approved the Company’s pending acquisition of the Grand Victoria Casino in Elgin, IL.

“In the second quarter, Adjusted EBITDA rose at 16 of our 20 properties as all four of our property reporting segments generated year-over-year gains including double digit Adjusted EBITDA growth in our East, West and South segments,” said Gary Carano, Chairman and Chief Executive Officer of Eldorado. “On a consolidated basis, second quarter Adjusted EBITDA rose 12.7% to $118.0 million, as our property level Adjusted EBITDA margin rose 290 basis points to 27.5% and our consolidated Adjusted EBITDA margin increased 300 basis points to 25.8%.

“Our strong margin growth, including property level and consolidated Adjusted EBITDA margin growth in every quarter since our May 2017 acquisition of Isle of Capri, reflects the benefit of our focus on disciplined marketing and promotion, advertising, food and beverage and labor expense management. Our record results also reflect success in driving better customer experiences across our property portfolio through an emphasis on market-leading guest services and targeted return-focused property enhancement projects. With the bulk of our planned major capital investments and enhancements complete in Reno, our recent rebranding of the three-property operations across six contiguous city blocks as ‘THE ROW’ has been met with an enthusiastic response from our guests. THE ROW leverages our integrated design and property enhancements and amplifies the convenience, amenities, entertainment and quality of Eldorado Resort Casino, Silver Legacy Resort Casino Reno and Circus Circus Reno. Our recent investments in the Reno market have resulted in revenue improvements with growth in high margin, non-gaming revenue channels. This fall THE ROW will open the The Spa at Silver Legacy, a 21,000 square foot spa that will offer our guests the largest relaxation, beauty, fitness and retail treatment facility in northern Nevada.

“Additional projects scheduled to be completed over the balance of this year include the renovation of approximately 400 rooms at Silver Legacy and the opening of Brew Brothers restaurants at Isle Casino Waterloo and Isle of Capri Casino Boonville. Following the opening of the two new Brew Brothers locations, the successful microbrew concept will be featured at five of our properties. In addition, renovations to all 402 rooms at our Black Hawk properties will begin at the end of the year and are expected to be completed in the first quarter of 2019.

“We are pleased with our 2018 results to date and expect that the Grand Victoria Casino and pending Tropicana Entertainment acquisitions, combined with the strong operations of our existing properties, will position us for additional growth in the future as we continue to pursue opportunities to create additional value for shareholders.”

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, transaction expenses, severance expense, costs associated with the Presque Isle Downs, Vicksburg and Lake Charles sales, impairment charges, equity in income of unconsolidated affiliates, (gain) loss on the sale or disposal of property and equipment, and other non-cash regulatory gaming assessments. 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 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.

Eldorado will host a conference call at 4:30 p.m. ET today. Senior management will discuss the financial results and host a question and answer session. The dial in number for the audio conference call is 719/325-4778, conference ID 6220773 (domestic and international callers).
