Post Brexit, Vodafone has followed EE's lead in reintroducing roaming fees for some mobile packages. We expect Virgin Media O2 and the MVNOs to follow suit, with H3G's approach more uncertain.

This move is somewhat inevitable as current arrangements leave operators exposed to up to €75 of monthly wholesale charges, and even more as legacy EU wholesale deals expire.

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.

BT’s revenue growth bounced back by 3ppts in Q1, and EBITDA growth surged into positive territory for the first time since 2018, enjoying significant bounceback as it lapped the start of the pandemic.

Some aspects of the bounce are temporary, but some business lines are yet to recover at all, and there are positive signs of an underlying return to sustainable growth across much of BT.

Openreach’s momentum continues to grow with much more to come, and VMO2’s switch to full fibre reduces a long-term upside but introduces no significant new downside in our view.

Vodafone’s growth this quarter was a touch disappointing; the annualistion of the COVID hit was a clear boost but no evidence of any tailwinds. The 1.1% growth in the European markets should be the real focus for investors.

We see some evidence of positive initiatives from Vodafone such as its new EVO tariffs in the UK but it still has much to prove on operating momentum, especially in Germany.

There are signs that Vodafone is slow-pedalling in some markets and with demanding EBITDA targets and with leverage still finely balanced, we expect this focus on profitability to continue. The UK may be a special case.

Openreach's new FTTP discount plan is focused purely on higher speed price discounts in return for accelerated adoption, with no further elements to disadvantage altnet new entrants.

The price discounts are, however, very aggressive and get more so over time, and allow Openreach CPs to undercut Virgin Media and retail altnets on gigabit pricing while still making strong margins.

The extra discounts do limit an upside for Openreach, but they should also stimulate FTTP take-up, promote market share gain from Virgin Media and altnets, and discourage further competitive build.

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.

Vodafone’s additional investment to boost a growth story that isn’t yet delivering failed to impress investors who value cashflow much more than promises for tomorrow, particularly given Vodafone’s track record with restructuring plans and product development.

It’s a surprising time to be splashing the cash with leverage still finely balanced and riding on Vodafone delivering a 10ppt turnaround in EBITDA growth next year vs last. Commercial activity looks set to continue to be dominated by EBITDA promises.

Selling a stake in Vantage Towers (temporarily) solved a leverage problem, but is creating a control problem, with the uncertain level of its future capex adding to investor concerns.

After a strong post-pandemic rebound, Sky has the opportunity to leverage its strong reputation with consumers to meet the challenge posed by new competitors and the studios’ direct-to-consumer transition, establishing Sky Q as the ultimate gatekeeper of video subscription homes.

Sports rights costs in Germany and Italy have been cut significantly, while Sky’s spend on UK Premier League rights will decrease in real terms. Savings will ease the financing of the shift to original content, which, associated with owner Comcast’s NBCU output, anchors the aggregation strategy.

Fibre deployment in the UK and Italy presents a subscriber and revenue growth opportunity, and underpins the gradual shift away from satellite to online content distribution.

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.
