Revenue rose to $369 million, from $88.4 million a year ago, the company said. Analysts polled by FactSet had expected Oscar to report a GAAP loss of 53 cents a share on sales of $598 million. Its membership grew 29%, it said. "We achieved very attractive first-quarter growth, while simultaneously lowering our medical loss ratio and administrative cost ratio year-over-year," Chief Executive Mario Schlosser said in a statement. Shares of Oscar ended the regular trading day down 7.4%. Oscar went public in March.
