 at certain orbital positions, reduce satellite lifetime in the case of an incorrect orbit injection, reduce functionality of the satellite, result in total loss of a mission and, to the extent that there are no other satellites that can be readily redeployed to carry the traffic that we were contracted for, could result in delays in the onset of projected revenue streams or loss of revenue. In addition, since commercial agreements are signed ahead of launch and generally include provisions allowing a customer to terminate the agreement if such launch fails, is delayed or launch failures are not remedied before an agreed date, any launch failure or delay could cause SES to lose customers to competing satellite operators. Even where launch failures or delays are remedied, such failures or delays could damage SES’s reputation. Satellite launch and in-orbitinsurance policies generally do not compensate for lost revenue due to the loss of customers to competitors because of interruption to services or for consequential losses resulting from any launch delay or failure. The occurrence of launch failures and launch delays could therefore have a material adverse effect on SES’s business, financial condition and results of operations. SES’s satellites may experience in-orbitdestruction, damage or other failures or degradations in performance that could impair the satellites’ commercial performance. A satellite may suffer in-orbitfailures ranging from a partial impairment of its commercial capabilities to a total loss of the asset. Such failure may result in SES not being able to continue to provide service to some of its customers. Satellite malfunctions, commonly referred to as anomalies, can occur as a result of:

| • |     | the satellite manufacturer’s error, including an undetected design, manufacturing or assembly defect, or the 
 use of a new technology that proves to be faulty;                                                            |

Confidential Treatment Requested by SES Pursuant to 17 C.F.R. Section 200.83

| • |     | problems with the satellite’s power systems, including circuit failures or other array degradation causing 
 reductions in the power output of the solar arrays on the satellites;                                      |

| • |     | problems with the satellite’s control systems; or |

| • |     | general failures, including premature component failure. |

| • |     | certain of SES’s satellites have experienced, and may in the future experience, anomalies or failures, which 
 could lead to:                                                                                               |

| • |     | a degradation in commercial performance; |

| • |     | a reduction in transmission capacity; |

| • |     | a reduction in the satellite’s operational life; |
