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.

BT had a solid-but-mixed Q3, with revenue growth slightly weaker than expected, EBITDA growth slightly stronger, and subscriber net adds a touch weak across broadband, mobile and Openreach 

The outlook is buoyed by a likely altnet slowdown at some point in FY26, with this set to help subscriber numbers at Consumer/Openreach and pricing at Consumer

The main cloud is the potential effect of a merged Vodafone-Three challenging BT/EE for best network and boosting MVNOs, a challenge we feel is real but manageable for BT

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.

Starlink has unveiled its plans for its next-generation satellites, boasting dramatically more capacity than was anticipated, as it aims to bring gigabit speeds to its broadband users.

This rapid growth in capacity poses the risk of a more commercially aggressive Starlink. While this will amplify its impact on the broadband market, it remains a somewhat niche consumer proposition but with additional B2B appeal.

Amazon's Kuiper is gearing up to begin launching its own satellites. While its target of introducing service later this year is likely to slip, Kuiper will bring an important peer competitor to Starlink, and will be the first time that Amazon's retail and marketing heft enters the UK connectivity market.

Sky UK and Warner Bros. Discovery have reached a deal for the pay-TV platform to carry WBD's Max, non-exclusively, when it launches in early 2026. The ad-supported version will be bundled at no extra charge for Sky and Now subscribers

The non-exclusive nature of the deal appears to have invigorated Sky into a restructuring of its packages, essentially unbundling Sky Atlantic for the first time

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)

Under financial stress, most streaming platforms are increasingly focusing on third-party distribution. Thanks to bundling, top streamers like Netflix can increase the lifetime value of subscribers, while smaller streamers widen their reach.

Bundles of streamers may have some potential in the US, but in Europe—with Netflix not interested—they do not have the necessary scale.

This trend towards bundling favours incumbent pay-TV aggregators like Sky and Canal+, but in the longer run they face competition from tech video marketplaces.

BT Group was hit by an unexpected slowdown in Global/Portfolio non-UK corporate revenue in Q2, with this impacting quarterly and full year expected revenue by 2ppts.

EBITDA, cashflow and all other operational metrics were steady or improving, with Openreach particularly strong, and without the non-UK impact it would have been a solidly good if unspectacular quarter.

The fibre-driven cashflow turnaround plan is therefore still very much on track, with the expected altnet slowdown/consolidation an added potential bonus, and the Vodafone-H3G merger a manageable challenge.

The UK altnets collectively lost over £1bn in 2023, with most metrics unrealistically distant from what they need to be for a sustainable model, particularly the smaller retail-focused operators.

Consolidation is essential for survival, and CityFibre at least has a reasonable case for long term sustainability with a wholesale model and Sky as a customer, and looks the most viable altnet consolidator in our view, with VMO2/nexfibre able to pick up the pieces should the sector fail.

A lack of long-term viability and related financing difficulties will dramatically slow network roll-out, reducing the altnet pressure on the rest of the sector even if consolidation improves penetration levels.

In the next fixed line regulatory review—TAR 2026—Ofcom is likely to maintain light regulation on Openreach’s pricing levels, while also maintaining strict restrictions on its pricing structures, which both help altnets. 

On other matters, none of the interested parties (Openreach/altnets/ISPs) look like getting exactly what they want, but by and large the industry will likely get what it needs—regulatory stability with a broadly pro-investment slant.

The next TAR in 2031 is likely to be more dramatic, but by our estimates, even a full return to cost-based charging will not result in significant wholesale price cuts, which is likely to be a relief to longer term investors in BT and the altnets alike.
