FOR IMMEDIATE RELEASE

MTR GAMING GROUP REPORTS SECOND QUARTER 2014 RESULTS

CHESTER, WV — August 8, 2014 — MTR Gaming Group, Inc. (NasdaqGS: MNTG) today announced financial results for the second quarter and six months ended June 30, 2014.

Second Quarter 2014 Results

For the second quarter of 2014, the Company’s total net revenues were $124.9 million, a decrease of 4.9% compared to $131.4 million in the same period of 2013.  Adjusted EBITDA in the second quarter of 2014 was $25.6 million, a decrease of 7.0% from the prior-year period, and adjusted EBITDA margin was 20.5%, a decrease of 40 basis points from the prior-year period.

“Our second quarter results were once again affected by a challenging regional operating environment,” said Joseph L. Billhimer, President and Chief Operating Officer of MTR Gaming Group, Inc.  “We were pleased with the continued strong performance of our Scioto Downs gaming facility, which has been a stellar performer since its opening in mid-2012 despite the increase in competition since that time.  Our Mountaineer and Presque Isle Downs operations were affected in the second quarter by another round of increased competition from Ohio’s expanding gaming market.  Looking ahead, our management teams remain focused on our core fundamental day-to-day operations as we evaluate the changing competitive environment in each of our markets and prepare for one more round of competitors opening in our region.”

The Company reported a net loss of $1.2 million for the second quarter of 2014, or $0.04 per diluted share, compared to net income of $2.4 million, or $0.08 per diluted share, in the same period of 2013.  Excluding $0.4 million in strategic transaction costs associated with MTR Gaming’s impending merger with Eldorado HoldCo LLC (“Eldorado”), the net loss in the second quarter of 2014 would have been $0.8 million, or $0.03 per diluted share.

Net revenues at Scioto Downs increased 2.3% to $38.4 million in the second quarter of 2014 compared to $37.6 million in the second quarter of 2013.  The property saw adjusted EBITDA increase to $13.0 million from $12.6 million in the comparable quarter of 2013, while the adjusted EBITDA margin at Scioto Downs increased to 33.8% compared to 33.6% in the prior-year quarter despite an increase in the amounts contributed to purses for racing by 1.5%.

Net revenues at Mountaineer Casino, Racetrack & Resort decreased 5.7% to $48.8 million in the second quarter of 2014 compared to $51.7 million in the second quarter of 2013.  Revenues from slots and table games decreased by $2.1 million and $0.6 million,

respectively, compared to the same quarter of 2013.  The property saw adjusted EBITDA decrease to $8.8 million from $9.9 million in the comparable quarter of 2013, while the adjusted EBITDA margin at Mountaineer decreased to 18.0% compared to 19.1% in the prior-year quarter.

Net revenues at Presque Isle Downs & Casino decreased 10.4% to $37.7 million in the second quarter of 2014 compared to $42.1 million in the second quarter of 2013.  Revenues from slots and table games decreased by $3.9 million and $0.4 million, respectively, compared to the same quarter of 2013.  The property generated adjusted EBITDA of $5.9 million compared to $7.4 million in the same quarter of 2013, while the adjusted EBITDA margin decreased to 15.5% compared to 17.6% in the prior-year quarter.

The decrease in the Company’s net revenues and adjusted EBITDA for the second quarter of 2014 was primarily attributable to additional gaming competition from Ohio, as well as continued competitive pressure from existing casinos in that market.

Corporate overhead costs totaled $2.1 million during the second quarter of 2014, exclusive of $0.4 million in costs associated with strategic initiatives, compared to $2.4 million in the prior-year period.

Six Month Results

For the first half of 2014, MTR’s total net revenues decreased 5.7% to $239.7 million from $254.1 million in the first half of 2013.  Adjusted EBITDA of $46.1 million decreased 12.2% from $52.4 million in the same period last year.  The 2014 year-to-date net loss was $7.4 million, or $0.26 per diluted share, compared to net income of $1.6 million, or $0.06 per diluted share, in the prior-year period.  Excluding $0.9 million in strategic transaction costs associated with MTR Gaming’s impending merger with Eldorado, the net loss in the first half of 2014 would have been $6.5 million, or $0.23 per diluted share.

See attached tables, including a reconciliation of net loss, a GAAP financial measure, to adjusted EBITDA, as well as the calculation of adjusted EBITDA margin, each of which are non-GAAP financial measures.

Balance Sheet and Liquidity

MTR Gaming-Eldorado Merger Developments

The Company’s previously announced strategic business combination with Eldorado pursuant to which the Company and Eldorado will become wholly-owned subsidiaries of Eclair Holdings Company (“ERI”), which will be renamed “Eldorado Resorts, Inc.”, remains subject to certain conditions and approvals, including regulatory approvals from gaming regulators in Pennsylvania, registration and listing of ERI shares and customary

closing conditions.  The proposed combination has been approved by MTR stockholders and gaming regulators in West Virginia, Nevada, Louisiana and Ohio.  The transaction is expected to close in the third quarter of 2014.  For more information about these milestones and other conditions and approvals required, please see the Registration Statement on Form S-4 and applicable amendments (File No. 333-192086) filed by Eclair Holdings Company with the Securities and Exchange Commission, as well as other relevant documents concerning the proposed combination.

Reconciliation of GAAP Measures to Non-GAAP Measures

Adjusted EBITDA represents earnings (losses) before interest expense (income), income taxes, depreciation and amortization, gain (loss) on the sale or disposal of property, other regulatory gaming assessment costs, loss on asset impairment, project-opening costs, strategic transaction costs, loss on debt modification and extinguishments and equity in loss of unconsolidated joint venture, to the extent that such items existed in the periods presented.  Adjusted EBITDA margin represents the calculation of adjusted EBITDA divided by net revenues. Adjusted EBITDA and adjusted EBITDA margin are not measures of performance or liquidity calculated in accordance with generally accepted accounting principles (“GAAP”), are unaudited and should not be considered as an alternative to, or more meaningful than, net income (loss) or operating margin as indicators of our operating performance, or cash flows from operating activities, as a measure of liquidity. Adjusted EBITDA and adjusted EBITDA margin have been presented as supplemental disclosures because they are widely used measures of performance and basis’ for valuation of companies in our industry. Management of the Company uses adjusted EBITDA and adjusted EBITDA margin as primary measures of the Company’s operating performance and as components in evaluating the performance of operating personnel.  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. Moreover, other companies that provide EBITDA and/or adjusted EBITDA information may calculate EBITDA and/or adjusted EBITDA differently than we do. A reconciliation of GAAP net income (loss) to adjusted EBITDA, as well as the calculation of adjusted EBITDA margin, is included in the financial tables accompanying this release.
