O2 has managed to deliver a solid financial performance over the past several quarters in spite of network constraints which are now resolved 

With signs that they are becoming more assertive in the market, and with continued brand strength and low churn, there is scope for that performance to hasten from here

Over the medium to long term, turnaround plans from the other MNOs could thwart outperformance by O2 but with an holistic culture of leading-edge marketing and innovation, we expect at least sustained solid results 

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
