In April, Walmart decided to close all 51 of its health clinics and shut its virtual healthcare operations, saying it could not see them as a sustainable business model to continue. The report added that some of the talks have involved health insurance companies, including Fortune 50 firm Humana. Although it is unclear whether any of the talks are ongoing, Walmart has made it clear through the process that it is attempting to recoup some of its massive investment in the clinics through a sale or other takeover arrangement, the report added.
