2 Form 4 filings for ASPN between 2026-09-24 and 2026-10-01, from 2 filers. 1 discretionary (1 sales, 0 purchases), 1 routine grant or withholding filing. 2 of 2 carry a dollar total (1 stated, 1 computed as shares × price), summing to $58,092,679; 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.
