Iridium NEXT Iridium Proprietary and Confidential 6 “All Systems Go” for satellite constellation replenishment $2.2 billion contract signed with Thales Alenia Space in June Coface guarantees for 90 percent of $1.8 financing package; syndication with major banks nearly completed Primary launch partner (SpaceX) under contract Renewed constellation management contract with The Boeing Company Opportunity for hosted payloads up to 50 kg Example = AMPERE program = collaborative public-private initiative with Johns Hopkins APL, The Boeing Company, Iridium and NSF to use magnetic sensors on existing Iridium satellites for measuring magnetic storm activity

Network Reliability Iridium Proprietary and Confidential 7 Cross-linked satellite constellation allows traffic to be rerouted in the event of an anomaly or outage on any given satellite Ground infrastructure has built-in redundancy for all key functions Quality of Service (QoS) performance indicators constantly monitored by network operations team

Network Reliability Iridium Proprietary and Confidential 8 Existing satellite constellation is projected to provide satisfactory service through deployment of Iridium NEXT Radiation resistant orbits, extensive radiation shielding for critical satellite components Extended battery life due to lower-than-design traffic loads Ample fuel on each satellite – burn rates minimal for station keeping Seven spares parked in orbit for rapid activation when needed Independent studies conducted during due diligence for Coface finance guarantees reveal that Iridium can continue to provide commercially acceptable service with a partial constellation
