Anheuser-Busch said Wednesday it’s investing $1 billion over the next two years to modernize its U.S. facilities.

Nearly half that amount will go to the company’s 12 major U.S. breweries, including its 169-year-old flagship brewery in St. Louis. Anheuser-Busch said it will spend $100 million for new can lines and $100 million on solar panel installation and other sustainability measures.

Anheuser-Busch, a subsidiary of Belgium-based AB InBev, said the investment will be spread across facilities in 26 states. The company has more than 120 facilities in the U.S.
