Yesterday,Amgen had briefing and in one question,an analyst asked about their cash,ability to raise cash for M&A. The reply was Amgen has good credit rating and comfortable cash generation.
Obviously ,there were no direct question on Onyx--except the one above.
But comments on R&D indicated worries for next few years for a block buster.The need for an acquisition to fill the medium term problem were obvious. I think Amgen will clinch the onyx deal eventually.
