Fitch Ratings analysts say they aren’t changing ratings for Wynn Resorts Ltd., Las Vegas Sands Corp. and MGM Resorts International despite a worse than expected situation in the lucrative Asian-gambling enclave of Macau that has dragged down finances. The ratings firm said Friday that they believe the three casino-hotel companies can withstand the pressures of Macau’s downturn which has been a result of a government crackdown on corruption leading to fewer high-roller gamblers visiting casinos.
