Michael R. McDonnell is CFO & EVP at BIOGEN INC. (BIIB). They have made 6 open-market trades across 3 companies since 2008, most recently 2025-05-15.
Unrated. We grade insiders only on stock they chose to buy on the open market. Grants, option exercises and vesting say nothing about timing, so they don't count — which is why someone can file often and still have no grade. It isn't a bad sign: unrated buys beat every graded tier below A.
0 open-market purchases, against 6 sales. Too few scored purchases to measure a record yet.
