Upon further reading, I think this may actually have something to do with the securities to be issued on conversion of Convertible Notes.
Maybe just revisiting and correcting for the Tranche A issue we had from a few months back. I imagine today would have been a good opportunity for a few convertible notes to be converted, particularly considering the volumes. Would be good to get them out of the way quickly anyway.
That's my hunch, but happy to be corrected by someone that actually knows something about corporate law and compliance.
