Direct greenhouse gas emissions from the UK telecoms sector equate to around 0.1-0.3% of the UK total. Most operators have set targets to reach net zero across their direct emissions in the next 10-20 years, with the move to electric vehicles an obvious win.

Network upgrades to 5G and fibre have the potential to cut emissions from electricity by a factor of 10, and consolidation offers further decarbonisation upside.

The industry could enable emissions savings in other sectors equivalent up to 30x its own by averting the need to travel and through IoT applications, with the latter requiring careful commercial assessment given the financial constraints in the industry.

VMO2 ended 2023 with strong ARPU and EBITDA growth, meeting its (revised) guidance for the full year, but saw receding subscriber momentum across both fixed and mobile.

2024 will be much tougher across the industry and for VMO2 in particular, with its revenue expected to be flat at best, and waning boosts from price rises and synergies coupled with a series of technical factors shrinking EBITDA.

The company has promised new commercial initiatives in 2024, and thereafter we see strong potential in it maximizing the use of its network and retail arms via breaking the long-standing lock between them, although the formation of NetCo is neither a necessary nor sufficient step for this.

There are various reasons why the mobile virtual network operators (MVNOs) have been adding many more subscribers than the mobile network owners over the past couple of years, including the cost-of-living crisis, and the expansion in their addressable market from the shift to online.

MVNOs' bargaining power to secure favourable rates has also improved sharply, with Lyca Mobile's move to the EE network indicative of their strengthened hand.

While some factors in their favour may wane over time, the prospective Vodafone/Three merger would be a marked positive, with the imperative on the operators to fill at least 25-50% additional capacity.

BT’s Q3 was robust in financial terms, delivering revenue growth of 3% and EBITDA growth of 1%, both in-line/ahead of analyst expectations.

Strong broadband ARPU and accelerating FTTP performance at Openreach were the highlights, a weakening BT Business and continued Openreach broadband losses were the main concerns.

This year’s guidance should be easily met, next year’s will be trickier given lower price rises due in April, but the long-term plan of a massive cashflow turnaround when the FTTP build ends is still well on-track.

Service revenue growth was broadly flat this quarter as some unwinding of price increases was compensated by a pickup in roaming revenues.

Vodafone has made some progress on its turnaround plan: it has sold its ailing Spanish unit; is rumoured to be in talks about a deal in Italy; and its German business is (just) back to growth (for now).

We expect muted guidance for 2024 with lower prospective price increases for most, inflated cost bases, and continued consolidation uncertainty.

BT continued to perform well financially in Q2, with revenue and EBITDA growth remaining robust, and full year cashflow guidance nudged up.

ARPU growth remained robust across fixed, mobile and Openreach, but subscriber growth was weaker, especially in mobile and Openreach, and this will become more of a concern if it persists.

Maintaining growth across retail divisions will be a challenge as the price rise effect wanes, especially in weak economic conditions, and while Openreach’s FTTP roll-out is going well, full success is still not assured.

With a difficult price rise adjustment now behind it, VMO2’s subscriber momentum is much improved, in part aided by accelerated network expansion.

Backbook pricing remains under pressure on the fixed network with revenues down 1.2% in spite of sizeable price rises and footprint expansion—upcoming OTS may exacerbate this issue.

VMO2 has thus far only countered the downside of the UK’s fibre revolution. A new approach to branding and expansion of its addressable market are upside opportunities—with the ultimate potential to even deliver improvements on its previous position.

Mobile service revenue growth finally got close to the rate of inflation this quarter, doubling to 7.5% as the operators benefitted from mid-teen price rises.

Growth will wane from here with expected revenue growth of 6% this calendar year and 3% next, with ongoing cost-inflation pressures.

H3G looks set to fare better than others on the top-line in 2024 but its profitability is looking somewhat irredeemable, with negative cashflow even with more normalised capex.

While VMO2's fixed price rises this year were always going to be quite tricky, the 1ppt boost to revenue growth was nonetheless disappointing on the back of price rises of 14%.

Both mobile and EBITDA performances were better, but H2 EBITDA growth will need to be considerably stronger to get to guidance levels, which will be all the more challenging with the loss of the Lycamobile MVNO.

With the erosion of VMO2's differentiators of split contracts and broadband speeds, growth at VMO2 will require addressing new parts of the market—both geographically and across the customer range.

BT got its financial year off to a strong start in Q1, with Group revenue and EBITDA growth of 4%/5% both well on track to hit guidance of merely 'growth'.

Price rises across broadband, mobile and Openreach all landed well, driving strong ARPU growth of 5%/9%/10% respectively, but subscriber growth was likely weak, mainly reflecting a tough environment.

Growth is set to wane across the year as consumer price rise boosts start to re-contract out, leaving Openreach as the main growth driver for as long as the economic environment remains challenging.
