On Thursday, Journal Register Company announced that it had been acquired by Alden Global Capital, a secretive hedge fund that specializes in “distressed opportunities,” such as companies emerging from bankruptcy — including newspaper groups. The acquisition may foreshadow additional moves by Alden, which is interested in two strategies to add value to its investments: (a) it wants its newspaper holdings to aggressively develop digital capabilities and revenues, and (b) it wants to see consolidation (mergers) among newspaper groups.
