- NOS, S.G.P.S., S.A. (NOS) is a leading Portuguese telecommunications and entertainment company providing fixed and mobile telephony, high-speed internet access, cable and satellite television, voice over internet protocol services, and mobile broadband. The company offers premium pay-TV channels including TVCine and holds a 25% stake in Sport TV, alongside operating thematic channels through Dreamia, a joint venture with AMC Networks International Southern Europe; it also engages in video production and sales, film distribution via NOS Audiovisuais (formerly ZON Lusomundo), operation of Cinemas NOS (Portugal's largest cinema chain), advertising on pay-TV channels and cinemas, datacenter management, IT engineering and consultancy services, cloud computing, cybersecurity, data and AI solutions, and electronic communications network infrastructure development. NOS serves residential, personal, and business customers across all market segments in Portugal, with an extensive fiber-to-the-home (FTTH) network covering 5.7 million households and leading 5G deployment recognized for coverage, quality, and speed.
Founded in 1994 as TV Cabo and headquartered at Rua Actor Antonio Silva, no. 9, Lisbon, Portugal, NOS emerged from the 2013 merger of Zon Multimédia and Sonae's Optimus Telecommunications, rebranding fully to NOS in 2014. The company operates primarily in the telco segment (fixed and mobile TV, internet, voice, and data services) and audiovisuals segment (content production, cinema exhibition and distribution, pay-TV and video-on-demand rights acquisition), positioning itself as a key digital transformation partner through partnerships with global technology providers such as Microsoft, Hewlett Packard Enterprise, AWS, Adobe, Cisco, and Google. NOS is a subsidiary of ZOPT SGPS SA and maintains significant market share, approximately 32% in key areas, supported by ongoing investments in research and development as Portugal's top private R&D investor in its sector.
In recent developments, NOS completed the acquisition of 100% of Claranet Portugal for €152 million in early 2025 following clearance from the Portuguese Competition Authority, enhancing its enterprise offerings in cloud, workplace, cybersecurity, data & AI, and managed IT services with Claranet's over 900 employees and €205 million in 2024 revenues; this move builds on a strategic cooperation agreement with the Claranet Group and aligns with ambitions for disruptive growth in the business segment. The company reported record 2024 performance with revenue growth, profitability, cash generation, and market share gains, alongside accelerated digital transformation including AI-enabled platforms and customer interfaces. NOS continues to expand 5G and FTTH capabilities while reinforcing sustainability commitments, including carbon emission reductions and human rights policies across its ecosystem.
