Marston's plc is a British pub and hotel operator. Founded as a brewery by John Marston in 1834, it is listed on the London Stock Exchange. In 2020, the company shifted its main focus away from its original brewing operations, entering it into a venture with Carlsberg Group's UK operations as Carlsberg Marston's Brewing Company. In July 2024, Carlsberg bought out Marston's remaining 40% share, ending the company's 190 years of owning breweries. Wikipedia
