Prysmian Group and Fincantieri agreed to acquire Xtera in a deal that reshapes the submarine telecom supply chain. The two companies signed an agreement to acquire Xtera through a joint venture led by Prysmian with an 80% stake, while Fincantieri holds 20%. The transaction values Xtera at an enterprise value of $65 million and is expected to close in Q1 2026, subject to regulatory approvals.
The acquisition positions Prysmian as a global player in submarine telecom systems, extending its established leadership in submarine energy cables into regional and long-haul fiber-optic networks. Xtera, headquartered in London with R&D operations in the UK and Texas, brings turnkey system integration capabilities, proprietary technologies, and a track record delivering subsea telecom projects worldwide. Prysmian and Fincantieri also plan to expand their collaboration beyond the acquisition, combining cable manufacturing, installation vessels, monitoring, and new security-focused underwater services.
Security and resilience emerge as central themes of the combined offering. Prysmian’s monitoring assets and cable production expertise will integrate with Fincantieri’s capabilities in unmanned underwater systems, guard vessels, and subsea security solutions. The companies point to growing demand from hyperscalers, data center operators, and incumbent telecom providers as AI-driven traffic growth accelerates investment in regional and transoceanic submarine connectivity.
- Joint venture structure: Prysmian (80%), Fincantieri (20%)
- Target: Xtera Topco Limited, a UK- and US-based turnkey submarine telecom systems provider
- Enterprise value: $65 million
- Expected close: Q1 2026, subject to regulatory approvals
- Strategic focus: end-to-end submarine telecom systems, including manufacturing, installation, monitoring, and security
- Market drivers: hyperscalers, data centers, AI-driven traffic growth, and long-haul connectivity demand
Raul Gil, EVP Transmission at Prysmian, said: “Thanks to the acquisition of Xtera we have made a significant leap forward in submarine telecoms, where growth is accelerating driven by the adoption of AI. As the market leader in submarine energy cables, we will now be competitive in delivering regional and long-haul telecom connections globally.”
🌐 Analysis
Prysmian is the world’s largest cable manufacturer and the clear market leader in submarine energy cables, with vertically integrated capabilities spanning R&D, fiber and cable manufacturing, advanced monitoring systems, and a globally deployed fleet of cable-laying vessels. Over the past decade, Prysmian has steadily expanded beyond energy into optical fiber and submarine telecom manufacturing, supplying critical infrastructure for long-haul and regional networks that underpin cloud, hyperscale, and international connectivity. Fincantieri, meanwhile, is one of the world’s largest shipbuilding groups and a strategic supplier of complex naval, offshore, and subsea platforms, with growing emphasis on underwater systems, autonomous vehicles, surveillance, and security technologies. Its expertise lies not only in vessel construction but in systems integration across defense, offshore energy, and subsea environments—capabilities increasingly relevant as submarine cables are recognized as strategic national assets. Together, Prysmian and Fincantieri form an industrial pairing that spans the full physical lifecycle of subsea infrastructure, from cable design and manufacturing to installation, protection, monitoring, and security. Their joint venture approach reflects a broader shift in the submarine market toward integrated, resilience-focused solutions, driven by geopolitical concerns, rising data center traffic, and hyperscaler demand for secure, high-capacity global connectivity.

Xtera occupies a distinctive position in the submarine telecom market as one of a small number of companies capable of delivering end-to-end subsea fiber systems at global scale, while remaining far smaller and more focused than the traditional Tier-1 system vendors. Its roots trace back to Xtera Communications, which built deep expertise in long-span optical transmission and subsea amplification before restructuring and re-emerging under H.I.G. Capital ownership in 2017. Since then, Xtera has concentrated on regional and long-haul submarine systems for governments, telecom operators, and private network owners, emphasizing open architectures, cost efficiency, and rapid execution. With roughly €130 million in revenue generated by a workforce of about 60 people, the company operates with unusually high revenue per employee, reflecting its role as a system architect and integrator rather than a vertically integrated manufacturer. The planned acquisition by Prysmian and Fincantieri effectively plugs Xtera’s system design, integration, and terminal expertise into a much larger industrial platform spanning cable manufacturing, installation vessels, monitoring, and subsea security—marking a strategic shift toward a fully integrated “one-stop shop” model for submarine telecom infrastructure as hyperscalers and AI-driven data center traffic accelerate demand for new subsea capacity.
