Divestiture
Selling a business or brand, sometimes because a regulator requires it.
A divestiture is a sale of part of a business. Companies divest voluntarily to focus, to raise cash or to exit a category.
The more interesting kind is a remedy divestiture, required by a competition regulator as the price of clearing a merger. The regulator identifies markets where the combined company would be too strong and requires specific brands or plants to be sold to a credible independent buyer. This is why some brands have a different owner in one country than everywhere else: the United States rights to Corona belong to Constellation Brands because a court-approved settlement required AB InBev to sell them.
