The Company had 13,226,773 ordinary shares of 1 pence each in issue (and there were 537,700 shares held in treasury) at the voting record time for the AGM. Therefore, the total voting rights in the Company for the purpose of the AGM comprised 12,689,073 votes.

The Board acknowledges the failure to pass resolutions 13, 14 and 15 (which are special resolutions). The Board still considers the flexibility afforded by these authorities to be in the best interests of the Company and its shareholders and it will continue to consider its approach on this matter and engage with shareholders as appropriate. The Board also notes that these have each previously received support at past AGMs.

The Board further acknowledges that resolutions 2, 5 and 12 received over 20% of votes against. The Board consulted with certain shareholders ahead of the AGM, and believes that the Chairman, as re-elected at today's AGM, possesses a good mix of skills and experience necessary to chair the Board and oversee the Company and deliver its strategy. We appreciate the support from most of our shareholders and will continue our engagement over the year ahead on the matters covering these resolutions.

The Board intends to host a shareholder forum to discuss questions received ahead of the AGM as soon as reasonably practicable and a further announcement will be made in respect of this in due course.
