Walmart currently has a co-branded Medicare drug plan with Humana that steers patients to Walmart stores. The partnership offers a prescription drug plan that can save up to 20 percent in drug costs for customers. In June, the insurer announced it would partner with Walgreens, with its unit operating senior-focused primary care clinics inside two Walgreens stores in Kansas, a move some analysts said at the time ended any speculation over a deal with Walmart. Reuters reported in March that Walmart was in early talks with Humana about developing closer ties, with a possible acquisition on the table. "Both of them (ties to Walmart and Walgreens) are complementary," Broussard said, adding partnering with one does not restrict the other deal. Unlike its rivals, Humana has said it will focus on partnerships and smaller deals while cementing its dominance in the Medicare Advantage business, which powered a better-than- expected second quarter profit.
