CVS on Sunday night said that it will acquire health insurer Aetna for around $69 billion in cash and stock. Four big questions that remain unanswered by this evening's press release:
1. What will be the relationship between CVS and those covered by Aetna insurance? For example, will an Aetna customer be required to purchase medications within the CVS network, or use urgent care facilities for services that can be handled by CVS MinuteClinic? If not, will there be surcharges for going to a rival pharmacy?
