ELDORADO RESORTS REPORTS FOURTH QUARTER NET REVENUE OF $428.2 MILLION, OPERATING INCOME OF $30.0 MILLION AND ADJUSTED EBITDA OF $91.1 MILLION

Reno, Nev. (February 22, 2018) – Eldorado Resorts, Inc. (NASDAQ: ERI) (“Eldorado,” “ERI,” or “the Company”) today reported operating results for the fourth quarter and full year ended December 31, 2017.

“Eldorado’s record fourth quarter results marked the conclusion of another active and productive year of growth for the Company in which we extended our success in expanding margins and growing financial results. Notably, the fourth quarter growth was broad based and reflects a continuation of the strong operating momentum we have generated since last May’s accretive acquisition of Isle of Capri,” said Gary Carano, Chairman and Chief Executive Officer of Eldorado. “Fourth quarter Adjusted EBITDA increased 16.3% to $91.1 million on essentially flat revenue reflecting a 300 basis point year-over-year improvement in our consolidated Adjusted EBITDA margin to 21.3%. Overall 14 of our 20 properties grew Adjusted EBITDA in the 2017 fourth quarter compared to the prior-year period, and for the full year 16 of our properties saw Adjusted EBITDA rise, which helped drive an 8.7% year-over-year increase in consolidated Adjusted EBITDA to $407.2 million despite a modest net revenue decline.

“We see a pathway toward meaningful additional margin expansion as we focus our operating strategies on practices that emphasize generating profitable revenue across the portfolio. Although we already surpassed our targeted $35 million of annual synergies from the Isle of Capri transaction, we are still in the early stages of rationalizing marketing and promotional spend across the enterprise and optimizing the acquired food and beverage operations. Isle of Capri Lake Charles is an example of one property that offers significant opportunity for improvement following the termination of the sale agreement for the property in the fourth quarter. We have identified significant cost reductions at the property based on our analysis of the operations of properties within our portfolio that have a similar revenue and competitive market profile. By deploying best practices across the portfolio, we also expect to generate further improvements in our legacy property operations.

“We continue to move forward with return-focused investments that improve our guests’ experiences and elevate our properties overall competitiveness in their markets. The comprehensive facility improvement program under way at our Reno Tri-Properties continues to drive higher visitation. To date, we have completed upgrades to nearly 1,000 hotel rooms and suites, updated food and beverage operations across the facilities with eight new or redesigned restaurants, cafes or bars now open, created new public spaces in all three properties and opened a new poker room and sports book. We believe that our spending in winter 2016 helped drive extremely strong results at the Reno Tri-Properties throughout the second half of the year. As a result of these strong returns, we have decided to accelerate additional investment in the Reno Tri-Properties in 2018, as we expect to spend $37.5 million of project capex in 2018 for further facility upgrades. We are similarly embarking on upgrades to the room product at our two Black Hawk properties beginning in late 2018 as we seek to capitalize on the strong economy of the Denver market.

“We entered 2018 with significant momentum and a comprehensive set of operating initiatives that will help us continue to grow our financial results. We believe that there are still many opportunities for Eldorado to build on our leading regional gaming platform which will help us further enhance shareholder value.”

Balance Sheet and Liquidity

At December 31, 2017, Eldorado had $134.6 million in cash and cash equivalents and $3.3 million in restricted cash. Outstanding indebtedness at December 31, 2017 totaled $2.2 billion, with no amounts outstanding on the Company’s revolving credit facility. Gross capital expenditures in the fourth quarter of 2017 and for the full year totaled $30.3 million and $83.5 million, respectively.

“We continue to improve our marketing and customer acquisition efficiencies and to lower costs across our entire property portfolio,” said Tom Reeg, President and Chief Financial Officer. “The 2017 fourth quarter results include a non-recurring, non-cash income tax benefit of $112.4 million resulting from the re-measurement of our deferred tax assets and liabilities as a result of the recently enacted Tax Cuts and Jobs Act. In addition, our annual free cash flow is expected to benefit from more than $40 million in

lower cash taxes over the next two years. The Tax Cuts and Jobs Act treatment of capital investment incentivizes us to bring high return growth projects online sooner and as a result, we expect full year capital expenditures of approximately $150 million, with approximately 50% allocated to project capex and 50% for maintenance capex.”

Operating loss was $(28.5) million compared to operating income of $14.9 million in the year-ago quarter. The operating loss for the South Region in the fourth quarter of 2017 includes total impairment charges of $38.0 million, including impairment charges of $13.2 million for Isle of Capri Lake Charles; $24.5 million for Lady Luck Casino Vicksburg; and $0.3 million for Isle of Capri Casino Lula.

In November 2017, Eldorado terminated the sale agreement for the property as the proposed buyer did not obtain required gaming approvals prior to the termination date.

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. Adjusted EBITDA represents operating income (loss) before depreciation and amortization, stock based compensation, transaction expenses, S-1 expenses, severance expense, income related to the termination of the Lake Charles sale, costs associated with the terminated Lake Charles sale, impairment charges, equity in income of unconsolidated affiliates, (gain) loss on the sale or disposal of property and equipment, and other regulatory gaming assessments, including the impact of the change in regulatory reporting requirements, to the extent that such items existed in the periods presented. 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.
