So let's say we have 300M shares OS, 100M owned by entity, and 2nd entity that wants to buy remaining 200M AS. They would have 40%, the other entity 25% and the remaining 35% in retail and other hands. No certainty for owning majority for party wanting to buy 200M.
However after a 5 to 1 RS they could buy 251M shares and own 51% of shares and be guaranteed majority.
