SES (company)

SES S.A. is a Luxembourgish communications satellite operator supplying video and data connectivity worldwide to broadcasters, content and internet service providers, mobile and fixed network operators, governments and institutions.

SES owns and operate over 70 satellites in two different orbits: geostationary orbit (GEO) and medium Earth orbit (MEO). These include European Astra TV satellites, the O3b and O3b mPOWER data satellites and others with names including AMC, Ciel, NSS, Quetzsat, YahSat and SES.

In April 2024, SES announced the acquisition of satellite services provider, Intelsat to create a more competitive multi-orbit satellite operator. The transaction is expected to complete regulatory approvals in 2025. The acquisition was first cleared by the UK Competition and Markets Authority in May 2025.

Based in Betzdorf, Luxembourg, and founded in 1985 as Société Européenne des Satellites, the company was renamed SES Global in 2001 and has been simply "SES" since 2006. The company's stock is listed on the Luxembourg Stock Exchange and Euronext Paris with the ticker symbol SESG and is a component of the LuxX, CAC Next 20 and Euronext 100 stock market indexes.

A book, High Above, telling the story of the founding of SES and the development of its first Astra satellites was published in 2010 to mark the company's 25th Anniversary, and was followed by Even Higher in 2012 and Beyond Frontiers in 2016.
