Hospital Corp. of America said it has completed a $564-million stock repurchasing plan. The offer to buy back 12 million of its common stock at $47 a share expired at midnight Monday. “This puts us in one of the strongest financial positions we’ve ever been in in the history of the company,” HCA spokesman Victor L. Campbell said. Campbell said the repurchase stems from HCA’s massive reorganization last year, in which the Nashville, Tenn.-based health-care chain sold many of its smaller, community-based facilities.
