Told you all...AZ is a PC company. Always has been, always will be. Why would a biotech lower itself to AZ's level. Took AZ's $60m 3 years ago and drops them today. AZ, can I get a few million? Worth asking because they're dumb enough to give it.
If you own stock in this company, sell it. If you work for this company, start looking for another job now. If you once worked here and found a way out, take some time to celebrate your positive life change.
