(Reuters) - Health insurer UnitedHealth Group Inc has at least a tentative agreement to buy specialty pharmacy operator Genoa Health from private equity firm Advent International, news website Axios reported, citing a source familiar with the deal.

Genoa Chief Executive John Figueroa will move on and Chief Commercial Officer Mark Peterson will run the business for UnitedHealth, the report bit.ly/2MvSFW7 said.

Both UnitedHealth and Genoa Health were not immediately available for comments.

Bloomberg had reported bloom.bg/2Mxb0Ce on Tuesday that Advent International was in talk with potential buyers about selling Genoa Healthcare, citing people familiar with the matter.
