InfraVia, Liberty Global and Telefónica acquire Substantial Group for £2 billion through their existing joint venture, nexfibre
- Transaction unlocks £3.5 billion* in international investment, underlining confidence in UK economy
- Acquisition creates sustainable, scaled network competition and wholesale choice in the UK
- Millions of UK consumers to benefit from faster access to full-fibre broadband
InfraVia, Liberty Global (NASDAQ:LBTYA, LBTYB, and LBTYK)) and Telefónica (TEF) have announced an agreement to acquire Substantial Group. Founded in 2019, Substantial Group, owned by investors Advencap, DigitalBridge and Soho Square Capital, is the UK's second largest alternative fibre provider, expected to have more than 3.4 million fibre premises and over 500,000 customers by completion. The acquisition will be made by the parties' joint venture company, nexfibre, and will unlock £3.5 billion of investment in the UK market.
The combination of nexfibre, Substantial Group's fibre network (Netomnia) and the customers on 2.1 million Virgin Media O2 premises (which will be upgraded to fibre by nexfibre), will create a scaled, financially secure challenger to BT Openreach, with a full fibre footprint of around 8 million premises by the end of 2027. When combined with the growing fibre footprint of Virgin Media O2, co-owned by Liberty Global and Telefónica, the two networks will collectively reach 20 million premises and give internet service providers a highly attractive wholesale alternative to the incumbent.
Infravia, Liberty Global and Telefónica are committing £1bn in new net funding for nexfibre to fund the transaction – made up of £850m from Infravia and £150m jointly from Liberty Global and Telefónica, with Virgin Media O2 committing traffic on 4.6m overlapping and adjacent homes.
In a joint statement, Vincent Levita, Founder & CEO, InfraVia Capital Partners, Mike Fries, Chairman & CEO, Liberty Global and Marc Murtra, Chairman & CEO, Telefónica said:
"By bringing our strengths together, we are creating a scaled and financially secure wholesale fibre challenger to BT Openreach - one that will enhance competition, strengthen the UK's digital infrastructure and deliver greater choice and quality for consumers and businesses.
"This transaction unlocks £3.5 billion in international investment and reflects our shared confidence in the UK as a highly attractive market for long‑term investment, supported by the government's economic policies. We are committed to accelerating full‑fibre coverage and helping ensure the UK remains competitive and ready for the future."
Rajiv Datta, CEO, nexfibre said:
"This transaction creates the largest alternative fibre platform in the UK, establishing the foundation for much-needed altnet consolidation, and sustainable wholesale competition. It will help drive innovation and deliver the economic and societal benefits that full fibre connectivity makes possible."
Jeremy Chelot, Group CEO, Substantial Group, said:
"This landmark transaction with nexfibre represents the natural evolution of the UK's fibre market. Consolidation has been inevitable, and this deal creates the scaled, sustainable platform needed to drive genuine wholesale competition. Importantly, our retail brand, YouFibre, will remain post-close, ensuring our customers continue to receive the same trusted service they know today, while benefiting from the financial strength and infrastructure scale this combination delivers. This is about building a stronger future for UK fibre."
