Market revenue growth sunk back to -3% in Q4 from -2% in Q3, with further backbook pricing and lockdown effects to blame .

Backbook pricing will improve with numerous price increases announced, but these will only start to take effect in Q2 2021.

Demand for broadband and ultrafast looks promising, but will also take time to filter through to revenue, with Q1 again lockdown-affected.

Ofcom’s full fibre regulation statement, released today, is largely as trailed, i.e. it allows BT’s Openreach considerable relaxation of wholesale pricing in return for building out full fibre.

On the longer-term regulatory prospects, Ofcom continues to be fair but more obtuse than it could and should be, unnecessarily dampening investor enthusiasm. Ofcom will decide on a case-by-case basis whether to allow Openreach to offer geographic/volume discounts, using slightly contradictory principles.

The publication and increased certainty may allow BT’s Openreach to extend its full fibre roll-out further, faster or even with external financing. The build plans of others will come under increasing question.

Virgin Media’s subscriber growth continues to be very strong, and it looks like next quarter’s price rise will (at worst) only stall, not stop, the renaissance.

ARPU was hit in Q4 by the postponed price rise, and it will likely remain in decline in 2021, with regulatory pricing pressure and lockdown effects still weighing, despite firm new customer pricing.

Nonetheless, accelerating subscriber growth is expected to drive group revenue growth positive again (helped by B2B growth), and Virgin Media’s main strategic problem—its fibre trilemma—looks like it will be dealt with after the merger with O2, expected to close mid-year.

BT’s December quarter results were mixed, with revenue growth improving but EBITDA growth worsening, and next quarter will be hit by the effects of lockdown 3 on mobile, with B2B likely to be hit by business failures following the end of furlough.

BT has maintained/nudged up its financial guidance regardless, and there are plenty of positive longer-term signs, with subscriber growth strong in the quarter, pricing pressure easing, and full fibre roll-out and adoption progressing nicely.

Overall, we expect the road to continue to be bumpy, but a recovery by 2022/23 still seems very plausible, ultimately driven by the wholesale and retail benefits of full fibre, and perhaps helped if it can get ‘Digital’ right, a particular challenge historically for BT.
