Race Beneath the Waves: Subsea Cable Consolidation Heats Up

EXA Infrastructure’s Aqua Comms deal signals a faster push toward owning critical subsea routes as data demand and resilience take center stage

20 Jan 2026

EXA Infrastructure has completed its acquisition of undersea cable operator Aqua Comms, marking another step in the consolidation of critical digital infrastructure as global demand for data continues to rise.

The transaction closed on December 31 after receiving regulatory approvals and meeting standard closing conditions. Financial terms were not disclosed. However, disclosures by Digital 9 Infrastructure, the former owner, referred to net proceeds of about $46mn to $48mn.

Undersea cables carry the vast majority of international internet traffic, supporting cloud computing, financial trading, streaming services and corporate networks. Control of these routes has moved from being a background utility to a source of strategic advantage, particularly as data volumes increase and geopolitical scrutiny intensifies.

Aqua Comms operates several key subsea cables linking Ireland with North America, the UK and mainland Europe. These routes form part of one of the world’s most heavily used digital corridors. By adding them to its existing terrestrial and subsea network, EXA Infrastructure has expanded its footprint across the North Atlantic.

The deal reflects a broader shift in the connectivity market. Large customers are placing greater emphasis on network resilience, route diversity and operational simplicity, rather than on raw bandwidth alone. Operators that own both subsea and land-based networks can reduce reliance on third parties and offer more integrated services.

Infrastructure investors are also reassessing their portfolios. Established subsea networks are costly and time-consuming to build, making them attractive assets for buyers with long-term capital as owners rotate holdings or seek to release cash.

The transaction comes amid increased regulatory attention on digital infrastructure, particularly assets that underpin national economies and cross-border data flows. Deals involving subsea cables are now more likely to face detailed review before completion.

Despite challenges linked to integration and regulation, demand for international connectivity continues to grow, driven by cloud adoption, artificial intelligence and expanding global data traffic. The acquisition of Aqua Comms underlines how competition beneath the seabed is intensifying, reshaping ownership of the networks that support the digital economy.
