It is a brewery in Munich that is owned by Anheuser-Busch InBev.
Here's the relevant part of the Wikipedia entry on Lowenbrau:
In 1975, Miller Brewing acquired the North American rights to Löwenbräu. Miller began brewing Löwenbräu with an Americanized recipe, and exports of Munich Löwenbräu to North America ceased.In 1999, the North American rights to Löwenbräu passed to the Labatt Brewing Company, which began to brew Löwenbräu in Canada for both the Canadian and US markets with the same recipe used in Germany.
Labatt's production of Löwenbräu ended in 2002 and exports of Munich Löwenbräu to North America resumed, although on a much smaller scale than had been the case before the Miller deal.
In 1997, Löwenbräu merged with Spaten-Franziskaner-Bräu to form the Spaten-Löwenbräu-Gruppe, which was sold to Interbrew in 2003.
In 2004, Interbrew merged with AmBev to form InBev, which in 2005 acquired Anheuser-Busch to form Anheuser-Busch InBev.
Proposals to relocate the Löwenbräu brewery out of the Munich city center have failed, despite the company's international ownership. Today, Löwenbräu has one of the oldest beer gardens in Munich.
