 the manner described above. Based on the assumptions described above under the section of this prospectus captioned “— Certain Assumptions,” the estimated aggregate amounts that would become payable to Intelsat’s current executive officers in respect of their unvested RSUs is $787,747, and unvested MC PSUs is $32,629,683. Potential Severance Payments Upon a Qualifying Termination Prior to or Following the Closing Employment Agreements Intelsat entered into employment agreements with each of its current executive officers (the “Executive Agreements”) that generally provide that if an executive officer is terminated by Intelsat without cause or by the executive officer for good reason, then the executive officer will receive:

| • |     | a lump sum payment equal to 1.5 times (2 times for Mr. Wajsgras) the sum of the executive officer’s                    
 then-current base salary, plus the executive officer’s annual target bonus for the fiscal year of the termination; and |

| • |     | Mr. O’Brien and Mr. Wajsgras will also receive COBRA coverage at active employee rates for 18 
 months.                                                                                       |

Severance benefits are subject to the executive officer timely executing and not revoking a
release of claims in favor of Intelsat and its affiliates and their respective predecessors and successors and the executive officer’s continued compliance with the restrictive covenant obligations.

Under the terms of the Share Purchase Agreement, the parties have agreed that, in recognition of the anticipated impact of the consummation of
the Transactions on the authorities, duties and responsibilities of each of Messrs. Wajsgras and O’Brien and Ms. Bryan (the “Designated Executives”), each Designated Executive will have Good Reason (as defined in the Intelsat
plan applicable to such Designated Executive) effective as of the Closing, subject to continued employment or service with Intelsat or its subsidiaries through the Closing, and, to the extent such individuals terminate employment within 60 days
following the Closing Date, each such Designated Executive will be deemed to have experienced a severance-eligible termination of employment effective as of the date of such termination of employment under the terms of the applicable Intelsat plan,
including such individual’s Executive Agreement. Notwithstanding the foregoing, Ms. Bryan and Mr. O’Brien may (but are not obligated to) individually agree in writing with SES to waive their respective right to resign for
“Good Reason” under clause (i)
