(Reuters) - Aetna Inc
Aetna also raised its full-year earnings forecast to a range of $5.00 to $5.10 per share, excluding items.
Susquehanna Financial Group analyst Chris Rigg attributed the stronger-than-expected results mostly to higher underwriting margins, especially in the Medicare segment.
The company also was active in stock repurchases, so the share count was lower, he noted.
Second-quarter net earnings were $457.6 million, or $1.32 per share, compared with $536.7 million, or $1.39 per share, a year earlier.
Excluding items, earnings were $1.31 per share. On that basis, analysts on average were expecting $1.25, according to Thomson Reuters I/B/E/S.
Quarterly revenue rose to $8.83 billion from $8.32 billion, helped by higher premiums from the company's Medicare and commercial healthcare businesses.
Aetna shares closed at $36.67 on Monday on the New York Stock Exchange.
