NEW YORK (TheStreet) -- Shares of HCA (HCA - Get Report) are slumping by 4.3% to $77.72 on Tuesday morning, despite the company posting better-than-expected results for the 2016 first quarter.

Before the opening bell, the Nashville-based hospital operator reported adjusted earnings of $1.71 per share, exceeding analysts' expectations of $1.49 per share.

Same facility equivalent admissions increased by 1.3% during the period and same facility admissions rose by 1.6%.

Hospital operators have been helped in recent years by a higher number of insured patients under the Affordable Care Act, although analysts have estimated that the benefits to hospitals could moderate, the Wall Street Journal noted.
