How would a motion to issue more shares work?
I put up a motion and it is voted on by shareholders. 1 share = 1 vote. The
company details page lists that 66% of the vote has to agree in order to issue new shares.
Can the initial motion be created by anyone with at least 1 single share?
No.
How would the price be determined for the newly issue?
The market price would be a large influence.
Main concern is that if more shares will be available, are the newly issued shares simply granted automatically to the highest bidder(s) first at their respective bid prices?
The GLBSE matches trades by price, so a higher bid would be met first.
