The Meeting Chairman has to go through the full agenda and allow for discussion from the floor. There will be votes on all the items and those who have been assigned proxies of others will have to substantiate their representation claims and vote their proxies.
An independent form like a trust company usually tabulates votes and often does not give an official count for days, although tentative vote totals will likely be known at the meeting itself.
The meeting does not start until 1pm EDT, apparently:
