Nestlé makes Kit Kat, except in America, where the Hershey Company makes it.
Rowntree's created Kit Kat and licensed its production in America to the Hershey Company.
When Nestlé acquired Rowntree's, it had to honor the Hershey Company's Kit Kat license.
So long as the Hershey Company is not sold, Nestlé cannot make Kit Kat in America.
Kit Kat is Nestlé's best-selling confectionery product globally, so of course it wants the Hershey Company to sell.
But whoever acquires the Hershey Company will not acquire Kit Kat, one of the Hershey Company's best-selling products, with it.
No Kit Kat decreases the Hershey Company's valuation.
As such, the Hershey Company is not incentivized to sell.
Nestlé should cut a 'Marvel Studios Sony Pictures Spider-Man' deal with the Hershey Company to make better Kit Kat in America.
