The Holiday Inn and Crown Plaza owner said it is on track to exceed 5% net room growth over the period, with the current pipeline at 289,000 rooms.
Group revenue available per room (revpar) in the third quarter was down 0.8%, with a 36% plunge in Hong Kong, expected to hit full-year financial results by US$5mln.
Comparable revpar was down 0.2% in the second quarter from the 0.3% growth in the first.
Mainland China and Americas dipped 2% and 0.6%, respectively, with US down 0.6% due to renovation activities and lower group business.
It was offset by 0.2% growth in Europe, Middle East, Asia and Africa, driven by continental Europe and the UK where London registered high international inbound demand.
“Despite the weaker RevPAR environment, and the challenges some of our markets are currently experiencing, we remain confident in our financial outcome for the rest of the year,” said chief executive Keith Barr.
Shares were down 2% to 4,627p in the early morning.
