AMC Theaters, the nation’s largest theater chain, announced Wednesday that it plans to reopen two-thirds of its US locations by September 3. More than 100 theaters will reopen by August 20. Shares of AMC surged more than 17% after the news. In June, the company said that the pandemic could push it into bankruptcy.
