Health insurance company Aetna Inc is said to have struck a deal to purchase Humana Inc for about $37 billion, or roughly $230 per Humana share, in a cash-and-stock deal.

Humana shareholders will get $125 in cash and 0.8375 Aetna shares for each share held, an about 23% premium to the stock's closing price on Thursday. Following the deal, Aetna's shareholders would own about 74% of the combined company.

Once done the new company will boast more than 33 million members, and bring in estimated revenue of about $115 billion per year. 56% of the revenue will be from government-sponsored programs like Medicare.
