Yum Brands, which owns KFC and Taco Bell, beat Wall Street estimates for third-quarter revenue and profit on Wednesday.
Strong sales at KFC and Taco Bell more than made up for further weakness at Pizza Hut, sending its shares up as much as five per cent.
Competition between big U.S. fast food chains has intensified as Yum, McDonald's and Domino's Pizza try to lure cash conscious customers with dollar menus, discounts and new breakfast items.
