CVS Health's $69 billion acquisition of Aetna will change the pharmacy and health-care industries alike. The deal creates the first health-care triple threat, combining CVS's pharmacy and pharmacy benefit manager platform with Aetna's insurance business.

The threat to pharmacies — or those that own them — is the way in which the two will leverage Aetna's network of 46 million members to drive traffic to CVS stores. Aetna subscribers will be able to pick up prescription medicine in CVS stores while receiving pharmacy and medical services. Eventually, they may also be able to find a lower co-pays only CVS.
