HCA Healthcare reported that recent hurricanes had and will have negative impacts on results, and shares slumped about 10% Friday afternoon. The insurer posted third-quarter earnings per share of $4.88, with revenue rising 8% to $17.49 billion. Both missed consensus forecasts. HCA says it 'incurred additional expenses and experienced loss of revenues estimated at $50 million, or $0.15 per diluted share,' associated with Hurricane Helene's impact on hospitals in Florida, Georgia and North Carolina.
