Acquiring money allows for expansion. When you examine all the things that Topgolf is doing to drive money to the bottom line, going public in some form brings in money faster than just using profits.
My guess is that WGT is an asset that does not perform the way Topgolf's other assets do in bringing money to the bottom line. Quite likely Topgolf has gotten what it wanted from the acquisition of WGT: that is technology and YuChiag Cheng.
Some of this would make for a reasonable assumption that WGT could be on the auction block.
