UK mobile service revenue growth was -0.1% in Q4, a 0.6ppt improvement from the previous quarter. This was helped by some modest price firming, continued strong data growth, and some inflation in handset prices

EE was the strongest growing operator after being the weakest just 12 months ago, with its efforts to improve customer service, network performance and perceptions of network performance starting to pay off. H3G had a strong H2, with strong customer additions while not sacrificing ARPU, although it is still clearly taking steps to manage capacity demand. O2 had another solid performance with a modest improvement in service revenue growth, and Vodafone suffered from weak ARPU primarily due to pricing pressure in the business market

The outlook for market service revenue growth is fairly positive, with ARPU-enhancing pricing moves in evidence, supported by continuing strong data volume growth, and existing customer price increases due to take effect from Q2 2017

Snap is going public: its filing shows widening losses and slowing user growth, calling into question its ability to reach profitability and justify the ~$20 billion valuation it is seeking

Long term, the company hopes to capture the large brand advertising budgets it expects will leave TV as linear viewing declines. But how it plans to do so is unclear, as it has shown little interest in connected TVs, and the ad model for augmented reality – Snap’s focus – is a long way off

Most of all, investors are being asked to trust in the ability of Snap’s founders – who will retain full control of the company – to continually innovate products which will attract users and advertisers

Virgin Media successfully ramped up its network extension in Q4, passing more than double the homes in the previous quarter, and above the rate required to meet 2017 expectations

Net customer additions were, however, relatively weak, entirely due to extra churn caused by the price increase implemented in the quarter. The price increase’s effect on ARPU and revenue growth was muted by ARPU discounting for new customers, leaving revenue growth broadly unchanged

Subscriber growth has already improved in early 2017, and is likely to continue to improve through the year. The discounted ARPU impact will be more sustained, but robust revenue growth is still likely throughout the year
