Update on Court Hearing and Timetable of Principal Events

Following discussions with the Court with respect to the time it may need to prepare for and hear representations by interested parties, Inmarsat announces that it has rescheduled the 12 November Court Hearing. It will now take place on 28 and 29 November 2019.

Currency Election Deadline

The new deadline for making a valid Currency Election is hereby extended to 6.00 p.m. (London time) on 28 November 2019. If the Court Hearing does not conclude on 28 November 2019, Inmarsat will make an announcement to extend the deadline for making a valid Currency Election to 6.00 p.m. on 29 November 2019. Any Currency Election which has been validly made by any Inmarsat Shareholder will remain active.

Any Inmarsat Shareholders who wish to make, amend or withdraw a Currency Election should read Part 7 of the Scheme Document. Unless a valid Currency Election is received by the Currency Election deadline, Inmarsat Shareholders will receive their Cash Consideration under the Scheme in US dollars.

Updated Timetable of Principal Events

An updated timetable of principal events is set out at the end of this announcement. As noted above, the Court Hearing has been listed for two days. It is possible, however, that the Court hands down its judgment on 28 November 2019. Therefore, the timetable below shows the expected timing of events for the following scenarios: (i) the Court Hearing concludes and the Court hands down its judgment on 28 November 2019; and (ii) the Court Hearing concludes and the Court hands down its judgment on 29 November 2019.

A further announcement will be made by Inmarsat on 28 November 2019 to provide an update on the progress of the Court Hearing.

If any further changes to the below timetable are required, an updated timetable will be announced by Inmarsat through a Regulatory Information Service in due course.

(1) These dates assume the Court Hearing concludes and the Court hands down its judgment on 28 November 2019.

(2) These dates assume the Court Hearing concludes and the Court hands down its judgment on 29 November 2019.

(3) This date may be extended to such date as Inmarsat and Bidco may, with the consent of the Panel, agree and the Court (if required) may allow.

Unless otherwise defined, all capitalised terms in this announcement shall have the meaning given to them in the Scheme Document dated 18 April 2019.
