Cash growth last year was financed by an increase in debt and a reduction in working capital, while almost all free cash flow was returned to shareholders through dividends and share buybacks. I expect that in the short term, an acquisition by Gilead would boost the stock, potentially by a lot, as earnings jump and the multiple improves. But over a period of say, five or 10 years, we can't know if Gilead 2.0 would be able to put up the same level of growth that its peers have, let alone what Celgene is already accomplishing.
