Many possibilities
a large partner or customer who wants to own a license and requires very large growth would be a good way to take the company to the larger size level quickly and also allows for long time holders and founders to sell some shares and enjoy the money a bit and start to manage their taxes in Canada which requires years of steady income drawing to minimize taxes or mabye a trust or something would be established to stretch it out.
Sankar bought 20M shares more than he ever expected when Jacobs sold out the bulk of his holdings since he wasn't going to be involved anymore, very much, since 2005-6.
So i think Sankar would be happy to sell some of this shares in the 3-5 dollar range as that's still a fair value to the buyer if things work out as planned in the years ahead.
