EGM means an extraordinary
general meeting: a shareholders’ meeting held outside the annual general meeting (AGM) to deal with specific or urgent business requiring member approval (for example, significant transactions, amendments to the constitution, capital raisings, or appointment/removal of directors).
The term is descriptive rather than statutory. In the UK, the Companies Act 2006 does not define “extraordinary general meeting” and treats such meetings simply as general meetings; the same is broadly true under Ireland’s Companies Act 2014. Nevertheless, “EGM” remains common in practice (including for listed companies) to distinguish a non‑AGM meeting.
An EGM can be called by the directors or requisitioned by members under legislation and the company’s articles. Notice, quorum, proxy and voting requirements are those for general meetings (including use of ordinary or special resolutions and, where permitted, shorter notice or hybrid/virtual participation). The label “EGM” has no independent procedural effect.
Usage and legal treatment are broadly consistent across England & Wales, Scotland, Northern Ireland and Ireland. In each jurisdiction, an EGM is simply a general meeting convened other than the AGM to obtain shareholder approval outside the annual cycle.
