Looks like they're ultimately owned by Concord Bicycle Music now (as of '19). It gets confusing in terms of who owns/operates that entity. But as of now, Concord Records - as subsidiary of Concord Bicycle - owns 100% of Fania, Fantasy, Razor & Tie, Rounder & Sugar Hill, Savoy, Tams-Witmark, Telarc, Varese Sarabande, Victory, Wind Up, & Musart among others.
If anyone can make heads or tails of Concord Bicycle, have at it. It looks to me as if Concord Music might be used as an investment shell by Concord Bicycle. I say that b/c Concord Music went in with a bunch of other companies to invest in Quiyer, Inc. That appears to be some social media platform. If you read between the lines here, reissuing the back catalog isn't likely on anyone's mind at any of these companies.
