Can you explain why not? I’m serious, not being snarky.
The company that buys up the Hostess brands already have employees and factories. It’s unlikely they’ll need the Hostess union workers or the Hostess owned plants.
Bakery X may already have a snack product line similar to Bakery Y. Bakery X would buy all property of Bakery Y to reduce competition. Could possibly at a later date re-release some products from Bakery Y as a limited time offer.
They might need some facilities, depending on who buys it, of course. Other companies will simply use their existing facilities and workers.
It could be that whoever owns it might part out the work to regional companies. Sort of the way Dr. Pepper is produced and distributed by Coke and Pepsi in different states (except Texas of course), even though its actually an independent company. (So is Big Red and it produces NONE of its own product).
I think that Little Debbie and BIMBO are two of the companies that might be interested in the trademarks and recipes.
