I can't speak to any other biotech stock paying a dividend other than Amgen. Amgen has been paying a dividend for many, many years. About 2% annually as of today. I invested back in 94-2000. Not very much but amazing how much it has grown. 3 - 2 for 1 splits. I don't want to sell cause its not in my Roth. Will deal with taxes way down the road when mandatory withdrawals begin. Been doing the DRIP with all out of Roth stocks. DRIP- Dividend Reinvestment Plan.

I am betting AMBS will pay dividends once they get the pipeline funded and they have plenty of revenue. They will get tons of help in the near future, IMHO, funding the pipeline.
