Iofina plc

("Iofina" or the "Company")

Grant of Share Options

Iofina (AIM: IOF), specialists in the exploration and production of iodine and iodine specialty chemical derivatives, announces that it has, effective from 13 June 2018, adopted an updated share option plan for the incentivisation and retention of key personnel. The Company adopted its initial share option plan in 2008 (the "2008 Plan"), the terms of which have not been previously amended or otherwise updated. The Company's board of directors (the "Board") considered it to be the appropriate time to review the terms of the 2008 Plan to assess whether any changes should be made to the terms to reflect the Company's current strategy and update any obsolete federal and/or regulatory references. The Board resolved to update the 2008 Plan to ensure it remains fit for purpose. The updated share option plan of the Company is to be known as the "Iofina plc 2018 Stock Option Plan" (the "2018 Plan").

The Company further announces that it granted on 13 June 2018, in aggregate, 1,980,000 share awards in the form of options over ordinary shares in the capital of the Company ("Ordinary Shares") under the 2018 Plan (the "2018 Options"). As at today's date, the options represent approximately 1.55 per cent. of the current issued share capital of the Company.

The 2018 Options will be exercisable at a price of 16.2 pence per Ordinary Share (being the closing price on 12 June 2018), with 50 per cent. vesting one year from the date of grant and the remaining 50 per cent. vesting two years from the date of grant. The 2018 Options are exercisable at any time prior to (and including) the day falling on the tenth anniversary of grant. In the event that any option holder leaves the Company, they will have a period of 90 days within which to exercise any vested options failing which they will lapse (the "90 Days Condition").

The grant of options under the 2018 Plan is part of the Company's long-term incentive arrangements designed to align the interests of the shareholders and certain executives.

There remain outstanding 985,000 share awards in the form of options over Ordinary Shares granted on 2 July 2011 under the 2008 Plan (the "2008 Options"), representing approximately 0.77 per cent. of the current issued share capital of the Company. The 2008 Options are exercisable at 30 pence per Ordinary Share and are exercisable up to (and including) 2 July 2021. The 90 Days Condition is also applicable to the 2008 Options.

The 2018 Options and the 2008 Options represent, in aggregate, approximately 2.33 per cent. of the current issued share capital of the Company.

In accordance with the requirements of the EU Market Abuse Regulation the 2018 Options have been granted to PDMRs under the 2018 Plan.

The total options granted over Ordinary Shares under the 2008 Plan and the 2018 Plan are detailed below.
