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

In China, Alibaba and Tencent compete for food delivery to expand access to a fast-growing source of mobile user data, using their chat and wallet super apps to funnel customers to their food delivery apps

In the West, the rivalry is direct between the food delivery apps – Just Eat, Uber Eats, and Deliveroo – and the costs of last-mile delivery dissuade challengers

In the UK, Amazon will change the game if it succeeds in its proposed purchase of a minority stake in Deliveroo, which Uber failed to buy last year. Progress on the merger of Amazon and Deliveroo is suspended by the regulator

Launched to the world in September 2017, TikTok is the first Chinese app to pose a serious threat to Western social media companies as it attracts hundreds of millions of Generation Z users around the globe

Privately-owned parent company Bytedance earned $7 billion in online advertising revenues in 2018 and is valued at $75 billion, placing it ahead of Uber as the world’s most valuable internet start-up, with an IPO likely this year

Bytedance’s goal of earning half its revenue outside China by 2022 is far from certain. In order to hit the target, TikTok will need to attain super scale with best-in-class revenue per user, an unlikely combination

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
