As at the date and time of the AGM, the total number of issued ordinary shares of the Company was 248,646,262 and the Company held 213,900 ordinary shares in treasury. The total number of voting rights for the ordinary shares was therefore 248,432,362. A vote withheld is not a vote in law and is not counted in the calculation of the proportion of votes ‘for’ or ‘against’ a resolution.

While Resolution 13, to approve the Directors’ Remuneration Policy, received support exceeding 90%, the Board notes that Resolution 14, to approve the annual report on directors' remuneration contained in the Directors' Remuneration Report, received approximately 70% support. Endeavour will therefore continue to engage with shareholders in the coming months and will publish an update on that engagement within six months of the AGM.

Copies of resolutions passed at the AGM, other than resolutions concerning ordinary business, will shortly be uploaded to the FCA’s National Storage Mechanism in accordance with Listing Rule 9.6.2 and available to view at: https://data.fca.org.uk/#/nsm/nationalstoragemechanism.
