("Idox" or "the Group")

Vesting of LTIP

Idox plc (AIM: IDOX), a leading supplier of specialist information management solutions and services, announces that the Board has revised the vesting date of Richard Kellett-Clarke's 2016 award under the Company's long term incentive plan to 14 March 2018. The award has now vested in full and has been satisfied by the issue of 1,900,000 ordinary shares of 1 pence each ("Ordinary Shares" and "LTIP Shares") to Mr Kellett-Clarke. The LTIP Shares are subject to lock in until 9 November 2019, however sufficient shares may be sold to discharge the tax liability arising. There are no other awards outstanding under the 2016 long term incentive plan.

Application will be made to the London Stock Exchange for the 1,900,000 new Ordinary Shares, which will rank pari passu with the existing shares in issue, to be admitted to trading on AIM and admission is expected to become effective on or around 21 March 2018.

Following the issue of the new Ordinary Shares, the Company's total issued share capital is 416,364,265  Ordinary Shares. The Company holds 1,491,219 Ordinary Shares in treasury. Therefore the total number of Ordinary Shares in issue excluding shares held in treasury is 414,873,046. The above figure of 414,873,046 Ordinary Shares may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
