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

Sky made a surprisingly weak start to 2019, with revenue growth decelerating to 1.9% (the first time below 4% since the European businesses merged in 2015), due to weaker ARPU trends

However, Sky expects improvement to follow, blaming one-off factors in the quarter. The ARPU weakness drove EBITDA down 11.3%, but this should bounce back across the rest of 2019 as football rights costs turn from a drag to a positive

Comcast highlighted collaborations with Sky across tech, advertising, content distribution and even news, stating it is on track to achieve the anticipated $500 million in annual synergies over the next couple of years

Market revenue growth accelerated to 3% in Q4, but it might never reach this level again, being helped by a never-to-be-repeated BT overlapping price rise

With price rises becoming more challenging in general, and superfast pricing under pressure in particular, maintaining/increasing ARPUs is becoming more difficult despite superfast volumes surging

Openreach’s ultrafast roll-out has accelerated, challenging Virgin Media and bringing the prospect of further price premia, but perhaps too late to be of significant benefit in 2019

Sky’s revenue growth under Comcast appears to have accelerated since it last reported as an independent company, largely driven by sports rights expansion in Italy, which also drove bumper subscriber growth in Q3 2018 

Sky UK likely enjoyed a steadier performance, helped by accelerating high speed adoption, a price rise in April, increased international sales, and improving premium channel adoption on third-party platforms

Comcast expects continued acceleration into 2019, with profitability taking a hit from increased sports rights in Italy in H1, but this is more than compensated for by reduced English Premier League rights costs in H2
