Two families that own major Hispanic-oriented grocery store chains throughout the Southwest got approval from a federal judge Tuesday to purchase the struggling Pro's Ranch Market chain's 11 stores out of bankruptcy, Dow Jones Daily Bankruptcy Review reported today. After reviewing the purchase offer at a court hearing, Bankruptcy Judge Sarah Sharer Curley said that she would approve it, according to Pro's Ranch Market attorney Frederick Petersen. The buyers' offer is worth about $53.6 million, according to court documents.
