HYLAS 4 Launch Update

Avanti is pleased to announce that it has agreed a Launch Slot for its HYLAS 4 satellite with Arianespace beginning 1st March 2018. The intended launch configuration for this slot will enable additional fuel to be embarked upon HYLAS 4 enabling it to reach geostationary orbit approximately 90 days earlier than would otherwise be the case.

Therefore, assuming the current launch manifest is maintained, HYLAS 4 will achieve geostationary orbit at approximately the same time as the previously announced launch date. Consequently, HYLAS 4 revenues would be expected to flow from July 2018 as previously planned.

Furthermore, this configuration also provides a lower mission risk profile and enables sufficient fuel to be embarked to support the satellite for up to 19 years in orbit, an increase of 27% over previous expectations.

This announcement contains inside information.
