Though the US-based Shelby Companies Limited (SCL) company oversaw relegation to League 1 - the first time the club have been out of the top two divisions since 1995 - they've caused a rebirth in response.
The club is first in League 1 - fourth points and two games in hand ahead of closet rivals Wycombe and are in the fourth round of the FA Cup as they host Premier League Newcastle United.
Although BSH retains 51% of the shares, Wagner said that Shelby will be "responsible for the operations of the club moving forward" and that "nothing about the way the transaction is structured will prevent us from achieving the long-term goals we have for the club.".
Since relegation in the 2010-11 season, the club have meandered in the Championship and met face with higher-ups negligence last season as they were relegated to League One.
Fellow Blues fan and former Microsoft executive Jeremy Dale, who helped broker the deal to bring American owners Knighthead to St Andrew's, has assumed the role of interim CEO since.
