The sale of the Boston Celtics was finalized on Tuesday, with private equity mogul Bill Chisholm taking over control of the NBA’s most-decorated franchise from a group led by Wyc Grousbeck that had owned them for more than two decades.

Five months have passed since an investment group led by Bill Chisholm agreed to purchase the Celtics from the Grousbeck family at a valuation of $6.1 billion.

Pagliuca told the Globe in March that he would be on the lookout for opportunities with other professional sports franchises.
