Boss Michael E. 4

What Happened

• Michael E. Boss, Co-Regional Market Director at Alexandria Real Estate Equities, reported dispositions related to restricted stock on 2026-01-23. The filing shows a forfeiture of 1,759 shares (reported as a disposition at $0.00, value $0) and a tax-withholding disposition of 149 shares at $59.69 each (total value reported $8,894).

Context

• For retail investors: forfeitures and issuer tax-withholdings are administrative actions tied to restricted stock awards and do not reflect open-market selling or a discretionary decision to divest shares. They generally do not carry the same market-sentiment signal as voluntary insider purchases or open-market sales.
