Frost funded the lion's share for the company for years and got warrants before they were able to raise traditional bank loans and lines of credit. The rest to a lesser extent did the same.
They keep loaning the company money at low interest and either hold their shares or to a minor degree, gift them to charities.
They wiped out prefered share classes and forced the conversion to common shares.
It's a perfect penny stock ownership story of insiders holding the same common shares as you and I own.
Even when the PPS jumped over $2, the insiders did not sell shares then.
Who would have known better to take advantage of the situation, and they did not.
