I imagine these meetings would take place on-site at the corporation in question and would mostly provide factual information similar to an actual RL shareholder meeting.
1. Our stock has risen/fallen x points this quarter. We anticipate earning/losses etc. because of z.
2. Our CorpSec team has dealt with x security events this quarter.
3. We plan to introduce x new product and are currently working on y so far unnamed projects that we plan to release in the next z quarters.
4. Any questions?
A simple format like the above with an opportunity for upper management PC's to publicly gloat about achievements while denying failures seems a solid foundation of a platform. I'm not asking for full open kimono transparency but rather some deeper player responsibilities into how corporations release information and more opportunity to publicly peacock the corporate lifestyle/theme.
