You need to understand the deal is closed, CVS does own Aetna. This cannot change as they own the company now. The issue is that the judge may block the integration of the 2 companies which means CVS Health would be forced to run the companies as separate entities and not mix the two together which is the intention of Larry. It would perhaps mean that those who are Aetna insured could not be forced to use CVS if at all. Regardless the company is owned by CVS.
Even though I found this post on another thread where it was posted by @WDmoQeQ-1uic , I see a lot of people don’t get the consequences of a potential blockage of the Aetna merger, so I thought it was worth reposting.
