Publication of inside information pursuant to Article 17 of Regulation (EU) No 596/2014 (MAR)

SES has decided to launch a buyback transaction for shares via acquisition of fiduciary depositary receipts (FDRs) to meet obligations under SES’s Equity Based Compensation Plan (EBCP). These FDRs will be repurchased on the basis of Article 430-15(3) of the law of 10 August 1915 on commercial companies, as amended, and will not be counted towards the 10% limit as authorized during the annual general meeting of shareholders held on April 2, 2026.

Under this share buyback transaction via acquisitions of FDRs, SES may acquire up to 2,967,519 FDRs (ISIN LU0088087324) at market price for an aggregate amount not exceeding EUR 31,158,949.50. The share buyback transaction via acquisition of FDRs is expected to be completed before the date of the next annual general meeting of shareholders or sooner if the maximum number of repurchased shares is reached earlier.

The buyback will be conducted in accordance with applicable rules and regulations, including the Market Abuse Regulation 596/2014 and the Commission Delegated Regulation (EU) 2016/1052. The buyback program will be executed by an independent intermediary, Société Generale. The timing of the buyback will depend on a variety of factors, including market conditions.
