Barry’s Jewelers plans to buy 72 stores.

The Duarte, Calif., company, which went public last April, said it agreed to purchase 63 Mission Jewelers stores in the Southwest and Southeast from Zale Corp. and nine jewelry stores in Oklahoma and Texas from a privately owned company. The stores, to be bought for an undisclosed amount of cash, will bring the company total to 209. The company also disclosed that it expects net income per share for the fiscal year ending May 31 to be 20% to 35% below the 87 cents a share in the previous year. Terry L. Burman, president, blamed the lower earnings on delays in installing a management information system and on higher-than-expected delinquency accounts.
