Centene Corp (NYSE:CNC) shares were rising Wednesday as the company announced that it was acquiring Fidelis.

The two health care providers will trade under the CNC ticker symbol following the acquisition of Fidelis, which will cost Centene $3.75 billion. The latter is the largest Medicaid manager care plan provider in the country.

The dear will help Centene bring in Fidelis’ business, which includes health insurance plans to New York state residents, amounting to 1.6 million people’s plans. Fidelis will become the combined company’s new health plan in the state.

Centene will have a larger presence in four more major states around the nation, including California, Florida, New York and Texas. The plans offered by Centene are the private-market option for Medicaid recipients.

“We think there is tremendous potential here,” said Michael Neidorff, Centene chairman and CEO, on a conference call with investors Tuesday. “Centene’s and Fidelis Care’s missions are fully aligned in terms of promoting health through high quality, accessible care and services for all and advocating for health policy that accords true dignity and respect for all people, especially the underserved.”

Fidelis’ state plans include Medicaid offerings, as well as Qualified Health Plans, Child Health Plus and Essential Plan. The company also offers national programs in Medicare Advantage, Dual Advantage and Managed Long Term Care.

“We have a strong mission… [and] a good strong business is good mission, ” said Rev. Patrick Frawley, Fidelis Care CEO. “I’m confident this acquisition will be [for] the good of our shared mission.”

CNC stock soared 6.5% on the news.
