JP Foodservice Inc. said it will buy Rykoff-Sexton Inc. for about $1.4 billion in stock and debt, creating the second-largest food wholesaler in the U.S.

JP Foodservice, which is acquiring a company twice its size in sales, said it will have annual revenue of about $5.2 billion after the purchase, with more than 130,000 restaurants, hotels and institutional buyers as customers.

The purchase will extend JP Foodservice’s reach into the western U.S. and into manufacturing.
