SES S.A. is a Luxembourgish satellite operator and one of the world’s largest providers of satellite communications services. Following its July 2025 acquisition of Intelsat for $3.1 billion, SES operates a fleet of approximately 120 satellites across geostationary orbit (GEO) and medium Earth orbit (MEO), serving broadcasters, telecommunications companies, airlines, maritime operators, and governments worldwide. The Luxembourg government retains a significant ownership stake in SES through Cassa Depositi e Prestiti-style mechanisms.
SES was founded in 1985 as Société Européenne des Satellites, Europe’s first private satellite operator. The initiative emerged from the Luxembourg government’s desire to establish the small nation as a global player in telecommunications—building on its legacy in commercial broadcasting through Radio Luxembourg (later RTL). Former Prime Minister Pierre Werner, who served as the company’s chairman from 1989 to 1996, was instrumental in bringing the project to fruition despite opposition from France and Germany.
The company’s first satellite, Astra 1A, launched on December 11, 1988, and revolutionized European television by enabling direct-to-home (DTH) satellite broadcasting. Early customers included Rupert Murdoch’s Sky TV and German broadcasters like Pro7, Sat.1, and RTL. SES pioneered the concept of “co-location”—positioning multiple satellites at the same orbital slot to increase channel capacity and reliability. Through decades of global expansion and acquisitions, SES transformed from a European broadcaster into a multi-orbit operator serving networks, mobility, and government sectors. The 2016 acquisition of O3b Networks added medium Earth orbit capabilities, and the 2025 Intelsat acquisition created a combined entity with pro forma revenue of €3.7 billion.
SES History
1985–1988
Founding & First Satellite
SES is founded on March 26, 1985, as Société Européenne des Satellites, with support from the Luxembourg government. The initiative builds on Luxembourg’s commercial broadcasting heritage (Radio Luxembourg/RTL) and aims to establish Europe’s first private satellite operator. Former Prime Minister Pierre Werner plays a key role in overcoming opposition from France and Germany. On December 11, 1988, SES launches its first satellite, Astra 1A, to the 19.2° East orbital position. Early customers include Sky TV (Rupert Murdoch), Pro7, Sat.1, and RTL.
1990–1998
European Dominance & IPO
By 1990, Astra satellites broadcast to 14 million cable and DTH viewers across Europe. SES pioneers “co-location”—positioning multiple satellites at the same orbital slot (up to eight at 19.2° East) for backup and increased capacity. German dish liberalization (1991) drives rapid growth, making Germany Astra’s largest market. In 1996, SES pioneers digital satellite transmission with France’s Canal+ after the Astra 1E launch. The 1998 launch of Astra 2A at 28.2° East establishes the UK/Ireland orbital position. SES goes public on the Luxembourg Stock Exchange (1998), trading as SESG.
1999–2001
Global Expansion Begins
SES embarks on aggressive international expansion beyond Europe, diversifying from TV broadcasting into telecommunications, broadband, and government services. Key acquisitions include: 34.13% stake in Hong Kong’s AsiaSat (1999), 50% of Nordic Satellite AB/SES Sirius (2000), 19.99% stake in Brazil’s Star One (2000), and 28.75% of Argentina’s Nahuelsat (2001). The pivotal 2001 acquisition of GE Americom from General Electric (valued at approximately $6 billion) establishes SES in the North American market. SES Global is formed as the parent company with two operating units: SES Astra (Europe) and SES Americom (Americas). The combined fleet reaches 41 GEO satellites—the world’s largest.
2005–2009
Further Consolidation
SES lists on Paris Euronext (2005) and acquires: stakes in Canada’s Ciel and Mexico’s QuetzSat (2005), German services provider ND SatCom (2006), and New Skies Satellites (2006), adding six satellites and coverage across Asia, Middle East, and Africa. In 2007, SES divests AsiaSat and Star One stakes as GE exits SES. SES Americom and SES New Skies merge into SES World Skies (2009). The same year, SES forms YahLive joint venture with Middle East operator Yahsat and makes its first investment in O3b Networks—a project to build a medium Earth orbit constellation serving “the Other 3 billion” (underserved populations).
2010–2014
Brand Unification
SES acquires remaining SES Sirius stake (100%) and in-orbit satellite Protostar-2 (renamed SES-7). In 2011, the company restructures under a single brand—SES—consolidating SES Astra and SES World Skies under unified management. Major satellite launches include: SES-4 (50th satellite, 2012), SES-5 (2012), Astra 2F (next-generation UK/Ireland, 2012), and SES-6 (2013). In April 2014, longtime CEO Romain Bausch (1995–2014) steps down after overseeing the company’s transformation from a four-satellite European DTH provider into a global operator with 50+ satellites. Karim Michel Sabbagh succeeds him.
2013–2019
O3b & Medium Earth Orbit
The first O3b MEO satellites launch in 2013, providing high-throughput, low-latency broadband to remote regions. SES increases its O3b stake and completes full acquisition in 2016 for approximately $730 million, making SES a multi-orbit operator. The O3b constellation reaches 20 first-generation satellites by April 2019. In 2017, SES-10 launches aboard the first flight-proven (reused) SpaceX Falcon 9 booster—a milestone for commercial satellite launches. SES develops the next-generation O3b mPOWER system, with launches beginning in 2021. Steve Collar becomes CEO (2018).
2019–2024
Connectivity & Transformation
SES broadcasts first 8K demonstration content via satellite in Europe (May 2019). The company pivots toward high-growth “Networks” segments (mobility, government, enterprise) as traditional video/media faces structural decline. O3b mPOWER satellite launches begin (December 2021), with commercial services starting in 2024. In June 2023, CEO Steve Collar steps down; Adel Al-Saleh (former T-Systems CEO) appointed in October 2023, taking office February 2024. GovSat partnership with Luxembourg government expands defense satellite capabilities. Revenue for 2024 reaches approximately €2 billion (pre-Intelsat).
2024–2025
Intelsat Acquisition
In April 2024, SES announces acquisition of Intelsat for $3.1 billion (€2.8 billion) cash plus contingent value rights. The deal closes on July 17, 2025, after regulatory approvals from UK CMA, European Commission, and US FCC. The combined company operates approximately 120 satellites (90 GEO, ~30 MEO) with pro forma revenue of €3.7 billion and a gross backlog exceeding €8 billion. SES expects €2.4 billion (NPV) in synergies with annual run rate of €370 million. FY 2025 reported revenue reaches €2.94 billion. The Networks segment (aviation, maritime, government) now accounts for ~62% of revenue, with aviation growing 145% year-over-year.
Key Figures
Pierre Werner (1913–2002)
Pierre Werner, who served as Prime Minister of Luxembourg from 1959 to 1974 and again from 1979 to 1984, was instrumental in establishing SES. As a visionary proponent of Luxembourg’s economic diversification, Werner championed the satellite project as a way to establish the small nation in global telecommunications—building on Luxembourg’s broadcasting legacy through Radio Luxembourg (later RTL).
The satellite initiative faced fierce opposition from France and Germany, who tried to block Luxembourg’s plans. Werner persisted, and though SES was formally established in 1985 (during the subsequent Santer government), it was Werner’s groundwork that made it possible. After leaving politics in 1984, Werner served as Chairman of the Board of SES from 1989 to 1996, overseeing the company’s transformation into a global operator. He became Honorary Chairman in 1996.
Werner is also remembered for the 1970 “Werner Report,” which outlined plans for European Economic and Monetary Union—a precursor to the euro. He died on June 24, 2002, in Luxembourg.
Romain Bausch (CEO 1995–2014)
Romain Bausch served as President and CEO of SES from 1995 to April 2014, a transformative 19-year tenure during which the company evolved from a regional European direct-to-home satellite provider into one of the world’s leading global satellite operators.
Under Bausch’s leadership, SES expanded from four satellites serving Europe to a fleet of more than 50 satellites providing coverage across the Americas, Europe, Africa, Middle East, and Asia-Pacific. Key achievements included the acquisition of GE Americom (2001), New Skies Satellites (2006), and the initial investment in O3b Networks (2009) that would later make SES a multi-orbit operator.
Following his tenure as CEO, Bausch continued to serve SES as a non-executive Director and was elected Chairman of the Board in 2015.

FAQs
What does SES stand for?
SES originally stood for “Société Européenne des Satellites” (French for “European Satellite Company”), reflecting its founding in Luxembourg in 1985 as Europe’s first private satellite operator. The company was renamed SES Global in 2001 after acquiring GE Americom, and has operated simply as “SES” since 2006. Today, the letters no longer officially represent an acronym—the company uses just “SES” as its brand name.
Who owns SES?
SES is a publicly traded company listed on the Paris Euronext and Luxembourg Stock Exchange (ticker: SESG). The Luxembourg government retains a significant stake through state investment mechanisms, and the company’s founding statutes provide Luxembourg with certain governance protections. Following the Intelsat acquisition, the combined entity remains headquartered in Luxembourg with a major presence in the United States. The Luxembourg government continues its partnership through initiatives like GovSat (defense satellite services).
What is O3b?
O3b is SES’s medium Earth orbit (MEO) satellite constellation, providing high-throughput, low-latency connectivity to regions underserved by traditional infrastructure. The name stands for “the Other 3 billion”—referencing the approximately three billion people who lacked reliable internet access when the project was conceived. SES initially invested in O3b Networks in 2009 and acquired full ownership in 2016 for approximately $730 million. The first-generation O3b constellation (20 satellites) operated at approximately 8,000 km altitude. The next-generation O3b mPOWER system began commercial service in 2024, offering flexible, software-defined capacity.
Why did SES acquire Intelsat?
SES acquired Intelsat in July 2025 for $3.1 billion to create a stronger multi-orbit satellite operator capable of competing against SpaceX’s Starlink and other emerging competitors. The combined company operates approximately 120 satellites with pro forma revenue of €3.7 billion and expects €2.4 billion (NPV) in synergies. The acquisition expanded SES’s spectrum portfolio, ground infrastructure, and customer base—particularly in aviation, government, and maritime connectivity. Together, SES and Intelsat represent “100 years of combined industry leadership.”
What is the Astra satellite system?
Astra is the brand name for SES’s European geostationary satellite fleet, primarily serving direct-to-home television broadcasting. The first Astra satellite (Astra 1A) launched on December 11, 1988, to the 19.2° East orbital position. SES pioneered “co-location” by positioning multiple Astra satellites at the same orbital slot—at one point, eight satellites shared 19.2° East—providing backup and increased channel capacity. Key orbital positions include 19.2° East (continental Europe), 28.2° East (UK/Ireland), and 23.5° East (Eastern Europe). The Astra system broadcasts thousands of television channels to over 180 million homes across Europe.
