Mobile sector returns are low, particularly for smaller-scale operators, with H3G earning less than its cost of capital. Regulatory initiatives, spectrum auctions and 5G look set to worsen this picture as H3G strives to gain viable scale

Back-book pricing is crucial to the returns of fixed challengers. Regulatory intervention is likely to lead to a waterbed effect in the fixed sector and exacerbate challenges in mobile

New entrant business case in full fibre is limited to de facto monopoly opportunities. There is the potential for BT’s returns to increase markedly if it gets full fibre right but new entrants’ inferior economics are unlikely to offer sufficient investor appeal

UK mobile market service revenue grew by 1.7% in Q2, up from 1.3% in the previous quarter, a disappointing result in the context of boosts from both IFRS 15 accounting and the annual price rises in the quarter

O2 was the star performer this quarter, with its service revenue growth leaping ahead to claim the top spot. BT/EE’s service revenue growth declined on an underlying basis, with weak contract net adds over the last six months catching up with it, and H3G and Vodafone were slightly improved and steady respectively excluding some one-off effects

Next quarter, the impact from the EU roaming cuts will annualise out, providing a substantial fillip to all operators. Ceteris paribus, this would put market growth in the vicinity of 4%, a figure not reached for years

The UK mobile market is growing strongly – we estimate revenues by 5% and EBITDA by 8% in 2017 – excluding one-off regulatory drags and the loss of non-profit-generating handset revenue

Regulatory price cuts end in mid-2018, and the handset effect will disappear from all reported figures from April 2018, leaving scope for very positive headline growth next year – considerably better than its European comparators and the sluggish UK fixed market

The outlook for the UK mobile industry is the best it has been in a decade, with significant growth in data demand, price increases, some supply constraints, rational competition, and major regulatory drags rapidly fading

Mobile service revenue growth dipped this quarter but this was likely entirely due to the predictable (and predicted) impact of the abolition of EU roaming surcharges.  On an underlying basis, growth improved

BT/EE extended its lead in both service revenue and contract subscriber growth terms. EE’s substantial investments in network quality and customer service have driven returns to scale, and its multi-brand approach is working well

Contrasting with the returns to scale seen at EE, TalkTalk’s MVNO has suffered the reverse of this, unable to break-even despite peaking at just shy of 1 million customers, and deciding to retreat to an agency model.  Sky Mobile is performing respectably well in context, but may be headed for scale issues itself
