NEW YORK — Restaurant Brands International says it’ll pay $1.8 billion for Popeyes, bringing the fried chicken chain under the same corporate umbrella as Burger King and Tim Hortons. The move fits Restaurant Brands’ strategy of taking over well-known fast-food chains that it believes have the potential for wider expansion. The deal gives Popeyes shareholders $79 per share, a 19 percent premium from its closing price on Friday. Restaurant Brands was created after Burger King, controlled by Brazilian investment firm 3G Capital, bought Tim Hortons in 2014.
