Do you perhaps know how this works legally? I'm curious. Did their contracts under Epic say something in the lines of, "on the event of ownership change your contracts are null and void" just like that?
M&A transactions can get pretty complicated for exactly these reasons; frequently, they disassemble the entire set of assets for sale and divvy them up across one or more buyers, who will pick and choose what they want and then reconstitute whatever they have purchased to their desired degree.
