Roadway Corp. is buying Arnold Industries Inc. for $21.75 per share in an all-cash deal that will add next-day delivery service to Roadway's existing freight operations. The deal is expected to close by the end of the year.

Roadway is the parent company of Roadway Express. It offers truckload and less-than-truckload freight services throughout North America. In addition to the logistics business, Arnold owns the truckload freight business Arnold Transportation Services and New Penn Motor Express, a next-day less-than-truckload carrier.
