NEW YORK — Wal-Mart Stores Inc. wrapped up its tender offer for Japanese retailer The Seiyu Ltd., which resulted in raising the retail giant’s stake to 95.1 percent from 50.9 percent. The discounter also said it wants to acquire the remaining shares of the supermarket chain, which would delist Seiyu shares from the Tokyo Stock Exchange. The completed tender offer also gives Wal-Mart managerial control of the struggling company.
