Chambers and Gilfillan have been looking to sell their 47 per cent stake in the organization for several months. It's believed Gallacher is looking to buy their percentage, along with an additional piece from Vanderbeek, who is expected to stay on board in a minority role.
According to Forbes' latest NHL team valuations, the Devils rank 19th among NHL teams in current value ($205 million), and posted an all-time high in annual revenue, net of arena debt payments, of $122 million, thanks in large part to running the Prudential Center and hosting approximately 150 non-hockey events per year.
Gallacher, the owner of the WHL's Portland Winterhawks, is the chairman of the Athabasca Oil Sands Corporation, as well as president and CEO of Avenir Capital Corporation.
According to two sources familiar with pending sale, Gallacher recently received an extension on his exclusive negotiating period. An announcement is expected as early as January 2013.
The Devils' expected sale comes in the middle of Collective Bargaining Agreement negotiations between the NHL and the NHLPA, which took another hit this past week when talks broke off in New York.
NHL Deputy Commissioner Bill Daly and NHLPA Special Counsel Steve Fehr spoke earlier today, but no formal talks are currently scheduled.
The NHL has declined to comment on the subject.
Gallacher came close to buying the Dallas Stars a few years ago before losing out to fellow-Canadian Tom Gagliardi.
