Shorter notice than required for an AGM of a PLC is permitted with a minimum member support of:

In a Public Limited Company (PLC), the requirements regarding the notice period for an Annual General Meeting (AGM) are typically outlined in the company's articles of association and are governed by company law. Generally, a PLC is required to give a minimum notice of 21 days for an AGM unless the articles specify otherwise.

Shorter notice can be validly given if there is sufficient support from the members. The minimum level of support needed to legally shorten the notice period for holding an AGM is 95% of the members, which indicates a strong consensus is required among the shareholders to proceed without adhering to the standard notice period.

This high threshold is designed to protect the interests of all members by ensuring that a significant majority agrees to waive the standard notice period, thus minimizing the risk of disenfranchising shareholders who may require more time to prepare for the meeting or to consider the matters on the agenda. In contrast, lower percentages like those in the other options do not meet the legal requirements, ensuring that all members of the PLC engage effectively in governance and decision-making processes.
