SABMiller's origins date back to the foundation of South African Breweries in 1895 as to serve a growing market of miners and prospectors in and around Johannesburg. Two years later, it became the first industrial company to list on the Johannesburg Stock Exchange. From the early 1990s onwards, the company increasingly expanded internationally, making several acquisitions in both emerging and developed markets. In 1999, it formed a new UK-based holding company, SAB plc, and moved its primary listing to London. In May 2002, SAB plc acquired Miller Brewing, forming SABMiller plc.
