Albertson's LLC has had a transformative year. The private-equity owned company is investing in trying to elevating its growth trajectory. A significant step in this direction was made when the group acquired the remaining Albertsons stores - and rights to the Albertsons name - from SuperValu, along with the Jewel-Osco, Acme, Shaw's and Star Market chains. Last week's acquisition of United Supermarkets builds on that foundation and comes as further evidence the firm, and its financial backers, are committed to driving growth through M&A.
