BT started its FY26 with robust financials. Revenue was slightly weak due to handsets and international, but EBITDA was slightly ahead of expectations, and operating metrics were strong.

The highlight was Openreach posting its lowest broadband line losses for over a year despite ongoing altnet pressure, and keeping revenue growth positive despite reduced inflationary price increases.

The altnet threat is still far from over, but it is encouraging that there are signs that it is beginning to wane as the sub-sector moves to a more rational wholesale model.

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.

Fixing an allocation quirk at BT pushed UK broadband revenue back into growth in Q1, albeit a very modest 0.8%, thanks to continued altnet growth and a very weak underlying market.

Broadband pricing is dipping down overall, but there is not yet evidence of pricing cuts targeted in altnet areas, a massive missed opportunity in our view.

The market will remain under pressure in the short term, but in the longer term altnet pressure will fall under all realistic consolidation scenarios.
 

The largest UK altnets are now all at or close to EBITDA positive, but still heavily cashflow negative even pre-interest costs and with paused builds, due to various below-the-line cash costs requiring continuous funding. EBITDA margins of as much as 35%+ are required to actually be cashflow breakeven.

Altnet economics are still challenging even if debts are fully written off, with a payback of more than 5 years on customer acquisition and connection costs alone.

The consolidation endgame is increasingly imminent, with the outcome likely to be a mix of CityFibre/VMO2 acquisitions, stand-alone niche players continuing, and abandoned assets, with the outcome for the rest of the sector more benign under any scenario than current trends.
 

The slowdown in telecoms traffic volume growth post-pandemic has persisted for far longer than a simple hangover effect would imply, and has spread from fixed broadband to mobile in many markets

The eventual emergence of the metaverse and/or AI-generated traffic may mitigate this trend, but it is hard to see growth ever returning to a sustained 30%+ per annum level, with around 10-15% likely to prove the new normal

While far from disastrous for telcos, it does have important implications, such as the need to structure pricing more carefully, focus on network quality over capacity, and be more wary of the threat (or opportunity) from MVNOs, FWA and satellite

The ‘big 4’ ISPs’ combined revenue remained in decline in Q4 2024 at -0.4%, partly due to a BT accounting quirk but mainly due to altnets gaining share

ARPU growth of 2% is roughly compensating for subscriber declines of 2%, but this ARPU growth is likely to weaken in 2025 as various boosts drop out

A recovery will come as the altnets slow in H2 2025 (if not before) due to their restrained expansion, which cannot come soon enough for the big ISPs

VMO2 had another mixed quarter to end a difficult 2024, with revenue growth improving but EBITDA growth falling, and other metrics mixed at best.

The company hopes to put this behind it with guidance for both revenue and EBITDA growth in 2025, a tough ask given current momentum.

Ultimately achieving or exceeding this may depend on altnet pressure receding, which we expect it to do, but perhaps more towards the end of the year than the beginning.

CityFibre has reported positive EBITDA in 2024, albeit at a slim 4% margin, and still needs further scale—and to successfully onboard its new wholesale customer Sky—to drive decent investment returns.

CityFibre’s organic build rate is dropping sharply as it (sensibly) looks set to rely on consolidation to achieve the required scale, with its organic build focused on Project Gigabit areas.

CityFibre remains well-positioned for consolidation, but this may take some time yet, with the altnet sector set to slow organic progress anyway in the interim.

The mid-sized UK altnets Zzoomm and FullFibre have agreed to merge, in what looks like an all-share merger of (nearly) equals, both of whom have been struggling to raise finance.

Why did they pick each other rather than the larger CityFibre/Netomnia/nexfibre options? Valuation may have been the key factor, but it has left them still vulnerably low scale with further consolidation necessary.

Much more consolidation is required for the sector to be sustainable in our view, and further financial distress may be required for realistic valuations to emerge.

Market revenue dipped into marginal decline in Q3, as both ARPU and sub growth weakened, both partly driven by the continued altnet onslaught
 

Backbook pricing effects will be of marginal help in the short term, but new customer pricing competition is still fierce, and households are still cash-strapped
 

In the longer term, pressure from the altnets should wane substantially as their roll-outs slow and they consolidate towards a wholesale model (or fail)
