Bangkok Dusit Medical Services Plc (BGH), Thailand's largest hospital group, expects to increase revenue by 13% and add four more hospitals this year.
Chief executive Chatree Duangnet said the new locations will be in Thon Buri, Rayong, Khon Kaen and Phnom Penh.
BGH, which operates the Bangkok, Samitivej, BNH, Phyathai and Paolo Memorial hospitals among others, has steadily pursued acquisitions and expansion in recent years.
The company recently boosted its stake in Krungdhon Hospital Plc (KDH), the second-smallest hospital stock in the 14-member SET Health Care Service subindex, in Thon Buri to 45% from 25% in a move to capitalise on proliferating development in that district.
The company has made a tender offer to other shareholders to buy the remaining KDH shares.
BGH has also been expanding in the Northeast to capitalise on that region's expanding economy.
It recently opened Bangkok Hospital Udon Thani and Bangkok Hospital Khon Kaen.
Bangkok Hospital also operates in Nakhon Ratchasima's Muang and Pak Chong districts.
Mr Chatree said BGH will expand its network to 50 hospitals by 2015 from 31 now including KDH, with a Myanmar location planned ahead of the launch of the Asean Economic Community in 2016.
"Our plans for Myanmar have yet to be finalised, as we're waiting to see what that country will do in terms of health-related legislation," he said.
Phillip Securities said BGH took in an estimated 50.8 billion baht in revenue last year, up by 14.6% from 2011.
Mr Chatree said some new hospitals may record an operating loss in their first year, but he remains upbeat that revenue from existing hospitals will still see healthy growth of 10-12% this year.
Shares of BGH closed yesterday on the SET at 149.50 baht, down one baht, in trade worth 363 million baht.
