'I want to be a grand­dad': Why John Maraganore left and where he (and Al­ny­lam) are go­ing

John Maraganore knew that peo­ple would be sur­prised when Al­ny­lam an­nounced his de­par­ture this morn­ing af­ter 19 years as CEO of the com­pa­ny. But he said it shouldn’t come as too much of a shock.

“Nine­teen years as a CEO lead­ing Al­ny­lam has been the great­est joy of my life, but 19 years has been a long time,” he said in an in­ter­view Thurs­day morn­ing. That’s “be­ing in the 24/7 op­er­a­tional mode of run­ning a com­pa­ny for 19 years.”
