Regent Hotel Singapore was opened 1988 as The Pavilion Inter-Continental Singapore, converted to Regent and managed by Four Seasons Hotel 1992. Following Regent's takeover by Carlson hotels in 1998, the hotel was rebranded as 'Regent Singapore, A Four Seasons Hotel' to distinguish it from other Regent hotels that were not managed by Four Seasons. Pontiac Land Group, of which the owner of the hotel, and Four Seasons, mutually agreed not to extend the management contract when it expired on 12/31/18. It was originally planned to have the hotel managed by Capella Hotel Group, an affiliate of Pontiac Land Group, yet a management contract with InterContinental Hotels Group was signed whereby the hotel stays within Regent's portfolio.
In March 2018, the InterContinental Hotel Group (IHG) announced that it has agreed to buy a 51% majority stake in Regent Hotels for $39 million and hopes to expand the brand's footprints to 40 hotels from the current six hotels.
