Wynn Resorts ( WYNN -1.83% ) isn't the biggest operator in Macau, but it may have the most riding on its recovery, given that 76% of property EBITDA (a proxy for cash flow) came from Macau in 2019. The company has invested billions in Macau, racking up $11.4 billion of debt in the process, so it needs the region to recover soon.
