Penn Entertainment reported a better-than-expected quarterly profit on Wednesday, as visitors return to its casinos and demand for online sports betting rises.

Shares of the company rose 15% in premarket hours. The company late on Tuesday announced a $2 bln deal under which it would rebrand its sports betting business, which is increasingly lucrative in the United States, with Walt Disney’s ESPN as ESPN Bet. Shares of rival betting firm DraftKings were down 4.8%.

The company reported early Wednesday second-quarter net income that more than doubled, to $78.4 million. Revenue from Penn’s “Interactive segment,” which includes online sports betting, increased 66.2% in the second quarter ended June 30.

“The company experienced stable property level performance in the quarter with each month showing sequential improvement”, CEO Jay Snowden said in a statement.
