Amendment Description	Eldorado Resorts, Inc. (“ERI”, the “Company,” “we,” “us” or “our”) filed its Annual Report on Form 10-K for the fiscal year ended December 31, 2019 (“Form 10-K”) with the U.S. Securities and Exchange Commission (the “SEC”) on February 28, 2020 and, on April 29, 2020, filed Amendment No. 1 to the Form 10-K solely to revise Part III of the report to include the information previously omitted from the Form 10-K. Due to printer error, the incorrect version of Amendment No. 1 was filed. This Amendment No. 2 to the report is being filed to correct the printer error and to file the version that was approved by the Company. This Amendment No. 2 to the report continues to speak as of the date of filing of the report, and except as expressly set forth herein we have not updated the disclosures contained in this Amendment No. 2 to the report to reflect any events that occurred at a date subsequent to the filing of the report. Pursuant to Rule 12b-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), this Amendment No. 2 also contains new certifications of the Company’s principal executive officer and principal financial officer pursuant to Section 302 of the Sarbanes-Oxley Act of 2002. Because no financial statements are included in this Amendment No. 2 and this Amendment No. 2 does not contain or amend any disclosure with respect to Items 307 or 308 of Regulation S-K promulgated by the SEC under the Exchange Act, paragraphs 3, 4 and 5 of the Section 302 certifications have been omitted. In addition, because no financial statements are included in this Amendment No. 2, new certifications of the Company’s principal executive officer and principal financial officer pursuant to Section 906 of the Sarbanes-Oxley Act of 2002 are not required to be included with this Amendment.
