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.

Sky has officially launched on CityFibre’s network, offering up to 5Gbps speeds, which may have more of a halo effect for Sky than driving direct adoption of these very high end packages.

Sky is critical to CityFibre’s wholesale model given its size, and it is a good sign that Sky is proving an enthusiastic wholesale customer, while it is likely to be wary of others.

CityFibre still needs to complete its planned financing round to kick off a wholesale-focused consolidation wave, which would ultimately be beneficial to all incumbents in ending irrational price competition from retail altnets.

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.
 

In a soft market for both consumer and B2B, service revenue trends continue to be dominated by in-contract price increase dynamics.

VodafoneThree’s launch signalled a cautious tone about prospects for mobile growth, presumably allowing for a degree of integration disruption.

VodafoneThree and VMO2 traded 79 MHz of usable spectrum, leaving VodafoneThree in a strong position spectrum-wise, albeit with some challenges given that its merger conditions reduce flexibility in its coverage approach.

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.
 

BT hit its FY25 guidance of a modest revenue decline coupled with modest EBITDA growth, and expects more of the same in FY26.

The highlight of the results was consumer broadband returning to subscriber growth despite the altnet onslaught; the lowlight was an increasing decline in Openreach broadband subscribers thanks to other Openreach customers (e.g. TalkTalk) not doing so well.

BT’s longer-term outlook and prospects for a dramatic cashflow turnaround remain strong, with Openreach net losses much more likely to improve than worsen over the next year, and further steps taken to divest/isolate erratic non-UK business segments.
 

Service revenue growth remained firmly negative at -1.0% in spite of inflation of +2.1%, as competition remains intense and pricing power weak.

Operators are guiding to a 2025 EBITDA performance that is broadly in-line with, or weaker than, their 2024 performance, with SFR choosing to abstain from guidance this year.

In-market consolidation cries are getting louder, with France, Italy and Germany the most obvious candidates.

Most regulations within the TAR26 condoc were continuations of the previous pro-investment regulations, albeit with little progress made on copper withdrawal, no extra help for the struggling altnets and a number of unexpected twists at the margin. 

Within the detail, the most significant hit is the return of cost-based price controls to some leased line charges, and across all of the proposed changes, Openreach has on balance fared worse than retail ISPs, albeit at a scale that is manageable within the BT Group.

Ofcom showed no inclination to offer any extra help to the struggling altnet industry, regarding its inefficiencies as being its own (and its investors’) problem, with consolidation the only sensible path forward for most.

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
