Taylor Made had something like $995 million in sales in 2015. A rudimentary means of calculating the value of a company is roughly 1x whatever the annual sales are. Fila bought Acushnet back in 2011 for roughly 2 billion, just for reference.... so even if you reduce the value price to 80 cents on the dollar, that's still well over a billion.
We know that he's got money, his net worth is around $825 million. If he was seriously considering purchasing the company outright - he'd need a couple of deep-pocket private investors, and I just don't see him assuming that type of financial risk.
The other aspect is that he was essentially Nike Golf... as great as he was all of those years, he still couldn't carry the brand in the end. Some will argue that Ben Hogan did okay for a while with his own brand, but it was still very much a niche market, in a very different economic era. It's worth noting that Hogan equipment has been bought and sold more than a few times over the years too. Last I heard - the only means someone can purchase new Hogan irons is via exclusive dealers, and even then they're special-order only - you can't buy a new set right off the rack. And when you think about that - they're pretty much going back to an era when that was the only way to purchase top-of-the-line golf equipment, going back to the 70's and 80's, direct from the manufacturer to the consumer.
Anyway... interesting to hear the rumor, but still very hard to imagine.
