Sands China, the Macau casino operator controlled by the American Sheldon Adelson, has not suffered any decline in revenue from high-stakes gamblers as the mainland's economic growth slows.
The firm's business is expected to be "very strong", and the second half is traditionally better than the first, chief executive Edward Tracy said. Mainland public holidays in the latter half of the year would boost growth, he said.
"We don't see anything on the horizon that's troubling," Tracy said.
Improved transport infrastructure on the mainland, including a high-speed rail network, will also have a positive effect, he said.
Shares of Sands China and rivals including Wynn Macau and Galaxy Entertainment dropped in Hong Kong trading earlier this week over concerns that slower economic growth on the mainland may hurt demand from high rollers in the world's largest gambling hub.
Sands China's sales are expected to rise by almost a third this year to US$8.56 billion, the average of 26 analyst estimates compiled in a survey.
