A Private investment firm has finalized its acquisition of Massillon-based snack maker Shearer’s Foods.  The investment firm had announced its plans to acquire Shearer’s back in December.  Although terms of the deal have not been disclosed, national media outlets have reported the sale to be valued at around $3 billion. It’s unclear whether the acquisition will alter local operations in Massillon and Brewster.  The investment firm has declined to comment about its plans for those two locations.
