General Meeting Details

Further to the announcement of 24 June 2021 and posting of a circular to the Company's shareholders convening a general meeting in accordance with Chapter 9.6 of the Listing Rules and section 656 if the Companies Act 2006, this announcement acts as an update regarding the General Meeting arrangements in light of the changing COVID-19 situation.

COVID-19

Since the publication of the notice of the General Meeting, the Board has continued to closely monitor the COVID-19 pandemic. From 19 July 2021, the UK Government will relax the COVID-19 restrictions, including those relating to social distancing and, as a consequence, it is legally permissible for shareholders to attend the General Meeting in person. No change is proposed to the place of the General Meeting which will be held at Nunn Close, The County Estate, Huthwaite, Sutton-in-Ashfield, Nottinghamshire NG17 2HW at 10.00 am on 20 July 2021. However, given the ongoing uncertainty around COVID-19 and rising cases, the Company's shareholders are encouraged not to attend the General Meeting in person and to appoint the Chair of the General Meeting or the Company Secretary as their proxy in advance. For further information about proxy voting, please see the Notice of General Meeting on the Company's website: https://nmcn.com/investors/. Shareholders must return their form of proxy to the Company's registrars by no later than 10.00 am on 16 July 2021.

Any shareholder who nonetheless wishes to attend the General Meeting in person is asked to register their intention to do so as soon as practicable by emailing [email protected]. Such shareholders should be made aware that the Company has decided to maintain its existing COVID-19 policy requiring the wearing of face masks, social distancing and other relevant precautions on the Company premises beyond 19th July 2021.

Shareholders are reminded that if they have any questions which they would otherwise have wished to ask in person at the General Meeting that they can raise those questions with the Board in advance of the meeting by contacting the Company at [email protected].

You may not use any electronic address provided in this announcement to communicate with the Company for any purposes other than those expressly stated.
