Biogen has great benefits- unlike regeneron- Depends on your current happiness with your manager and if the new manager would be better- money will be a wash and they Don't have RSU's or ESPP.
Not true ~ they have great benefits (almost equal to Biogen) and they also grant Stock when signing on and annually. Additionally, they are paying BIG sign on bonus. They also have a robust pipeline and your initial stock award alone could bring you $250,000 in the near future. I hope the Biogen HR department got all the information they need above
Be careful comparing Biogen with Regeneron when it comes to stock. REGN is WAY over its reasonable valuation now (P/E approaching 150; and that's just one metric that's way off) The PCSK9 market is not going to be easy; several competitors, heavy managed care/pharmacy benefit company influence, and a company that is arrogant beyond belief. Read their CP board to hear the experience of recent candidates, INCLUDING some that actually got hired. The grass is not always greener. BIIB has a great future pipeline and your really need to tread lightly before leaving there. The frustrations with the organization at BIIB are common to a lot of companies.
Their P/E is off? Way off of what? You can't compare P/E of mature developed product portfolio (Biogen) with $8b revenue to Regeneron's $1-2b. Learn and understand financial metrics before using them in your analysis. Their P/E of 150 is based large off of as yet unrealized earnings. We have a more mature portfolio, and earnings stream. Once (if) Regeneron's MABs gain approval, earnings will grow, adjusting their P/E accordingly. Also, CP is far from representing an accurate cross section of employees. It's a blank canvas for the discontented, doesn't capture those that are happy of fulfilled.
