5 Form 4 filings for NPKI between 2026-08-19 and 2026-11-03, from 5 filers. 4 discretionary (3 sales, 1 purchases), 1 routine grant or withholding filing. 4 of 5 carry a dollar total (3 stated, 1 computed as shares × price), summing to $342,335; 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 $9 to $14.
