Longterm, your Advisor used the word "expect." That would seem to indicate he believes there is a good possibility of an announcement after the Shareholders meeting. He is likely using the public knowledge of AVXL, those extraordinary items to be voted on at Shareholder Meeting and the situations that are currently in play along with his 30 years of Biotech experience to make a 'Logical Deduction' that there is likely a situation that needs one or more of the items to be voted on before the 'development' can be finalized.
Here is one possible scenario which I think is at least somewhat likely:
Biogen (or less likely) another Company wants to do a collaboration with AVXL. However Biogen, since it will be providing capital to run trials wants an equity stake. Dr. Missling and the BOD do not want to risk losing control or to be unduly influenced by Biogen (or other company)so they made a deal for an equity stake but with Preferred shares with NO VOTING RIGHTS Therefore, this DEAL can not be announced until the preferred shares are authorized at the Shareholder Meeting. A corporation can not have common shares with no voting rights, it must be a separate class of shares according to Corporation and Security Laws.
This also solves the question of; Why the Preferred Shares?
'Expect' does not mean he has inside knowledge just his very logical deduction that they would not likely authorize Preferred Shares without some plan to use those. So the Announcement after the Shareholders Meeting should be related to the Preferred Shares in some manner.
