The $3.8 million from Mohegan Las Vegas was just a fraction of Mohegan Gaming’s $444.3 million collected this quarter from its network of casinos, including the flagship Mohegan Sun in Connecticut, Mohegan Pennsylvania and Resorts Atlantic City. Mohegan Gaming did not provide a 12-month revenue total for the casino that it has operated since March 2021 through a management agreement. The 60,000-square-foot gaming space saw a 42 percent revenue decline in the three months that ended Sept. But the record haul wasn’t because of the Mohegan Las Vegas casino, which is operated as part of Virgin Hotels.
