WAG is taking a gamble on AB (60% of their biz is wholesale) 90% of pharmacy biz is in London.
No access to markets like France/Spain/Germany...
adam has a link to a nice article that talks about AB biz.
WAG is betting on purchasing synergy however, WAG doesnt realize generic manufacturers sell different labeled/ manufactured product in different countries based on FDA and EU laws.
I think funds will still own WAG shares but will be over weight CVS.
