Bangkok Basketball Holdings were the second team to join the league. The team will be the second Thai team, after the defending champions Chang Thailand Slammers.[2] The third team to join the league was SSA Saigon Heat organised by the Saigon Sports Academy. The Heat are the first international basketball team to represent Vietnam.[3]
The Brunei Barracudas, a team that has failed to make it to the playoffs in the league's first two seasons, has decided not participate in the 2012 season. While no reason was given, the team has heavily relied on its starting five, who are all imports, to play the game in its entirety.[4]
Six of the eight teams participated in the To Be Number One Basketball Challenge held in Bangkok in benefit of the victims of the 2011 Thailand floods. The San Miguel Beermen defeated the AirAsia Philippine Patriots to win the championship.[5] In 2012, the Beermen, the Patriots and the Qatari team Al -Jaysh will participate in another preseason tournament at the Ynares Sports Arena in Pasig.[6]
