Sept 12 (Reuters) - Health insurer Centene Corp said it would buy privately held Fidelis Care for $3.75 billion to enter New York, the second largest managed care state by membership in the United States.
The company's stock rose 6.7 percent to $97 in aftermarket trading on Tuesday.
The acquisition would help Centene expand its government sponsored healthcare coverage with a leadership position in New York, the company said.
Fidelis Care, a not-for-profit corporation, offers affordable health insurance coverage to New York residents and has over 1.6 million members in the state as of June 30.
Centene said the deal, which is expected to close in the first quarter of 2018, would significantly improve the company's earnings per share.
