Vesting of shares under the 2014 Performance Share Plan (PSP)

Awards over ordinary shares of €0.0005 in Inmarsat plc under the Performance Share Plan made in March 2014 vested on 19 March 2017.

Vesting of the award was dependent on 3-year TSR vs the FTSE350 (excluding Investment Trusts) and 3-year EBITDA growth, measured over the three years to 31 December 2016 and weighed equally.  A vesting outcome of 30% of the element for TSR (or 15% out of 100% of the total award) and 66% of EBITDA (or 33% out of the total award) vesting occurred and therefore 48% of the total award vested.

Mr Sukawaty received his share award when he held an executive position in the Company and the number of shares that vested was subject to a time pro rata reduction.

The PSP is not a HM Revenue & Customs approved plan and on vesting, income tax and social security deductions become payable by the individual. 

The share price at which shares were sold on 20 March 2017 was £7.9206 per share.  Where shares have been retained they will be added to the existing number of ordinary shares for the relevant individual.
