Benefitfocus announced this week at its largest ever user group meeting the addition of property insurance products to its BenefitsPlace portfolio, which doubles its addressable market, Piper Jaffray analyst Sean Wieland tells investors in a research note. Improved customer satisfaction and investments in the platform give the company a competitive advantage, and "should drive growth for years to come," says the analyst. He estimates every 1% of eligible lives who purchase auto could generate over $6M in transaction revenue for Benefitfocus. The addition of property and casualty further strengthens its value proposition to clients and partners, says Wieland. He keeps an Overweight rating on the shares with a $59 price target.
