Innovation and Technology Doing the same for less: Normalised CapEx and cost reduction 1/ Improved space technologies X 2/ SES scale advantage DO Electrical propulsion Improved mass efficiency A More launcher options ☑ Re-usable rockets Reduced cost A Shorter time to space (w) Full digital processing Improved mass efficiency A Flexibility enhancement DIO Economies of scale Improved satellite efficiency enables to reduce number of primary satellite in global fleet GEO-MEO capital allocation flexibility Increased economies of scale Improved time to market Satellite life management Refuelling enhanced monetisation A Shorter life - reduced obsolescence SES SES's Normalised CapEx development EUR million 655 2017 100 Saving target 555* 2022 Normalised CapEx ■Saving target *Excludes scope change of SES-17 and 03b mPOWER Doing more for the same: Increase addressable markets HTS and hosted payloads, inclined satellites monetisation ▲ Benefit from recent innovations to add HTS payloads on video Satellites SES-12/SES-14/SES-15 ▲ De-risk investments with strong pre-commitments + video existing contracts + joined developments of HTS payloads with aero-connectivity provider ▲ Improved business cases with hosted payloads: allocate room and power to third party customers on SES satellites: leverage fleet, to offer low cost to space and short time-to-market (GOLD, WAAS, EGNOS) ▲ Improved asset monetization leveraging SES fleet, and offering mobility service with satellites reaching end of life (Inclined orbit) SES investor presentation I September 2018 MEO investments: 03b mPOWER in 2021 ▲ 7 super-power satellites will complement existing generation of 20 satellites ▲ Scalability: capable to serve up to 30,000 beams across 400M Km² ▲ Flexibility: beams 100% usable 100% of the time, directing connectivity only where it is needed Economics: Small, fast, easy-to-install equipment costs and time to service → Enhanced CapEx efficiency 03b mPOWER I Addressable market increased by 5x Current MEO 11
