MEMPHIS, Tenn. — Fred’s Pharmacy posted its Q1 results Tuesday, and though the company swung to a roughly $36.5 million net loss, as its transformation continues, it’s seeing tangible results, particularly in pharmacy and front-end sales in renovated stores. The company also said that it is working with Rite Aid and Walgreens to bolster the case for the Federal Trade Commission to approve Walgreens’ acquisition of Rite Aid that, if approved, would make Fred’s the third-largest drug store chain in the United States
