Blum owns of 5,367,726 shares according to the April 18th filing. And no, as erroneously posted, you don't multiply that figure times 3 for the 3 Blum companies. Blum owns of 5,367,726 shares. Period.
As of last SEC filing on 4/18, the total is 17,779 + 5,367,726+ 5,418,329 = 10,803,834 shares.
My bad. You're right.
