10 Form 4 filings for REGN between 2026-08-12 and 2026-11-03, from 7 filers. 10 discretionary (2 sales, 8 purchases). 10 of 10 carry a dollar total (6 stated, 4 computed as shares × price), summing to $16,258,348; a multi-transaction filing without a stated total contributes only its largest transaction, so the sum is a floor and the true figure is higher. Prices ran $377 to $869.
