The Humana-backed primary care provider has closed its initial public offering after its share price more than doubled post-IPO.

Oak Street Health, the US-based primary care provider backed by health system owner Humana, closed its initial public offering at approximately $377m yesterday.

The company floated on Thursday last week pricing more than 15.6 million shares on the New York Stock Exchange at $21 each to raise $328m.

Oak Street’s shares closed at $44.00 on Monday, giving it a market capitalisation of about $10.6bn, before the underwriters bought more than 2.3 million more shares through the over-allotment option.
