As we expected, UK mobile operators are beginning to introduce EU roaming tariffs, with EE taking the first major leap in the hope that others will follow.

This move is somewhat inevitable as current arrangements leave operators exposed to up to €75 of monthly wholesale charges.

We don't envisage a return to the days of super-normal returns from roaming, but it is nonetheless conducive to much-needed price inflation in the sector.

The last lockdown caused service revenues to dip again to -7% in spite of some easing of roaming pressure and the annualisation of some early pandemic weakness.

The heralded, elevated in-contract price rises will fail to drive higher growth this year due to lower inflation—we estimate zero impact at BT/EE relative to 2020 and a reduction in revenue momentum of around 0.5ppts for each of the other operators.

The annualisation of the first lockdown is the most meaningful upside from here with a boost of around 5-7ppts possible. However, some pandemic upsides will also unwind, notably lower churn and enhanced B2B demand with the latter vulnerable to the end of furlough support and the economy.

Market revenue growth improved to -1.4% in Q1 2021, a partial recovery being better than at any point in 2020, but still worse than at any point in 2019.

Next quarter the sports channel suspensions will lap out, driving strong (but temporary) year-on-year growth.

Longer-term revenue growth recovery will need backbook pricing pressure relief, which will start in Q2, and demand for ultrafast broadband.

The highlight of what seems set to be O2’s final results as a standalone company is OIBDA growth of almost 8% in spite of a drag from weaker net adds.

It has also been a good quarter for O2 strategically with preliminary merger approval and contiguous 5G spectrum although that may be matched by its peers in subsequent deals given H3G’s openness to negotiation.

The annualisation of COVID impacts as well as an improving mobility picture will provide a significant boost to trends, although the roaming drag seems unlikely to reverse any time soon and O2’s relative growth will suffer from lower in-contract price rises than peers this spring.

BT ended a very challenging 2020/21 financial year with its worst quarter yet for EBITDA growth, as the third national lockdown impacted mobile, offices, pubs/clubs and installation revenue streams

There are many turnaround drivers ahead though, including price rises, backbook effects annualising, lockdown effect reversals, and full fibre benefits, but returning to revenue growth by the end of the year still looks challenging

The acceleration and expansion of fibre build is very positive in our view, but BT has given no guidance on the future benefits aside from capex returning to normal levels, which is doing it no favours with investors

Virgin Media’s subscriber boom continued into 2021, despite a marked price rise in Q1, benefiting from lockdown and continued demand for higher speed broadband.

ARPU remained weak in Q1, suppressing revenue growth, but this will recover (somewhat) in Q2 as the price rise takes effect, countering the current disconnect between volume and revenue growth.

The merger with O2 is set to complete in June, with much operational pre-merger preparation already done, but the key strategic questions appear yet to be decided.

A move away from premium sport is long overdue from BT, with there having proved to be little strategic, 'halo' or other cross-over benefit to its core broadband and mobile businesses.

BT Sport has managed to dramatically increase its pricing since launch, with little evidence of significant net subscriber leakage, which has driven 'standalone' profitability and allows a partial or full sale.

A sale would not likely cover BT's full losses to date, but a partner could enhance the value of the asset, and an eventual full sale would reduce risk for BT and enable it to fully focus on its broadband and mobile core businesses.

Spectrum auction assignment stages are normally fairly dull and routine, but due to the two-part nature of the 5G auctions, and the critical importance of proximity and contiguity, this is not the case with 5G.

The assignments won, combined with the Vodafone/O2 deal, ensures that all the operators enjoy at least 80MHz of (essential) proximity, but only O2 gets (nice-to-have) contiguity.

Further swaps could ensure contiguity for all, but this requires H3G to co-operate, which is in its absolute, but not relative, best interests.

Europe’s larger MNOs are falling over each other to demonstrate support for OpenRAN, which has become a primarily operator-driven standards initiative, with governments also firmly behind it.

This is driven by a desire to improve equipment interoperability from the current de facto monolithic standards, improve supplier diversity, and ultimately drive down cost.

While some movement towards interoperability is perhaps overdue, OpenRAN is not a panacea, and some trade-offs between price, performance, supplier diversity and reliability have to be accepted.

The sector rebounded slightly in the quarter to December thanks to a seasonal improvement in the roaming drag, although the partial lockdown tempered the recovery.

We await imminent news on spectrum trading, and there may also be some licence fee reductions as a consequence of the lower prices in the recent 5G auction.

While the sector is likely to continue to struggle into Q1, the outlook is much brighter thereafter thanks to the annualisation and even reversal of some lockdown effects, and to higher price increases from the spring.
