Insider activity — BSEMBioStem Technologies, Inc.

16 Form 4 filings for BSEM between 2026-08-20 and 2026-11-03, from 10 filers. 16 discretionary (0 sales, 16 purchases). 2 of 16 carry a dollar total (0 stated, 2 computed as shares × price), summing to $1,000,000; 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 $2 to $2.
