UK altnets: CityFibre progresses, altnet consolidation set to accelerate

CityFibre has announced that its long-awaited £1.5 to £2.3 billion financing round is finally agreed, with it now able to use this money to fund its remaining organic build, integrating acquisitions, and covering operating losses until it reaches cashflow breakeven.

This capital raise will not be the first of many across the altnet sector in our view, as CityFibre’s business model is unique, and now partially dependent on the struggles of others to encourage consolidation.

CityFibre now has all the pieces in place to accelerate consolidation of the altnet sector, which will ultimately benefit the whole sector in ending unsustainable retail altnet competition.

Altnet losses expanded to £1.5bn in 2024, as EBITDA losses persisted and interest costs rose sharply, with ARPUs weakening and operating costs stubbornly high, and the increasing interest burden looking unpayable under any reasonable scenario.

Even the best performing altnets can barely make EBITDA breakeven, and not make sufficient margins to cover ongoing customer acquisition investment, resulting in a perpetual cash drain for their investors.

The impact on the rest of the sector is worsening in the short term as pricing falls, but this should accelerate the inevitable consolidation into a sustainable wholesale model under CityFibre and/or VMO2/nexfibre.

Broadband market revenue continued to decline by 1% in Q3, thanks to stagnant broadband volumes and weak ARPU growth. 

Pricing is declining at 5-10% per annum as a modest retail altnet slowdown is countered by TalkTalk losses moderating, and competitive pressure remains intense.

Recovery looks very much dependent on the retail altnets consolidating into a more sustainable wholesale model.
