Hope it helps!!!

first two answers are close, but not quite there.

I'm adding another suggestion because I disagree with shareholders meeting. There are two types of meeting, the annual general meeting (AGM), which has to be held every year to approve the annual accounts, and the extraordinary general meeting (EGM) which is called when certain items have to be discussed/approved, and can therefore occur several times per year as required. Therefore, all meetings are general meetings (attended by the shareholders)

Following Amara's recommendation, I made a Google search and this is what I found out for "General Meetings":

"The KAS meets on the first Friday of every month at 7:00 p.m. at the Kalamazoo Area Mathematics and Science Center (KAMSC). Meeting days and times may vary, please check the Schedule of Events page before attending a meeting".

or

" The aim for the meeting formats is to have three different formats occurring over a cycle of three months. These will be guest speaker / forum discussion / beginners session .

The dates for the upcoming 2001 meetings are as follows:

Wednesday 19 September
Session 1: Peter Lowe on Cosmology in the 20th Century.
Session 2: Video on An Astronauts' View of Earth. "

As you might see, nothing to do with "Asambleas", or Shareholders' Meetings, where only shareholders and very special guests such as an Examiner, are allowed to attend.

I also found "General Shareholders' Meetings" or "Special Shareholders' Meetings" which stands for Ordinary and Extraordinary Shareholders' Meetings but again, this term is not under question. Only the "Asamblea" term is, which certainly means "Shareholders' Meetings".

I concluded that "General Meetings" stand for public meetings and here, we are talking about the corporate affairs of a corporation.

Hope to have clarified all doubts.

I have no doubts that one can say shareholders' meeting or shareholders meeting or meeting of the shareholders, with or without apostrophes (pedantic question, but at least with general you don't have that problem), however I shall continue to use "general meeting" for GB English, which is all I do. If you look a little closer, there are lots of hits for annual and extraordinary general meetings in the search, which was my previous point, and in this context, I really don't think that anyone would be confused about what is being talked about (i.e. the possibility of it being a "general meeting" that has nothing to do with shareholders).
I hope that has clarfiied any doubts, but just in case I AGREE that you can say shareholders meeting, I'm just pointing out another (in my opinion valid) possibility. When it comes to finance/business there are LOTS of differences in GB/US usuage, and for the sake of the glossary, we should not only put them, but accept them.

From the Longman Dictionary of Business English

company meeting: a meeting of the members (shareholders) of a company. The holding of these meetings is governed by law: every meeting must be properly convened (called) by giving due notice to everyone having a right to be present; it must be properly constituted (composed) with a quorum (minimum number) of members and a chairman. There are several kinds of company meeting. Syn. shareholders' meeting
annual/ordinary general meeting
extraordinary general meeting
statutory meeting In Britain the 1st meeting held after the company commences business

Therefore, as I said before, apart from the first meeting, all are general meetings, either AGM or EGM. The Web continues to return more results than shareholders
