The craft beer-maker was sold to Heineken International, the world's second-largest beer company. Lagunitas had already sold a 50-percent stake to Heineken in 2015.
The company has headquarters in Chicago's Douglas Park neighborhood and Petaluma, Calif.
Tony Magee, who founded Lagunitas, explained Thursday in a Tumblr post that the deal is about expanding the brand across the world.
