O2’s Q4 results delivered market-leading service revenue growth of 3%, double-digit EBITDA growth, sustained strong net adds and low churn. 

With ARPU service revenue growth flat, all of the growth came from other service revenue including M2M (machine-to-machine) and MVNO; a lumpy category up by more than 40%. 

Following a period of strong outperformance, O2 will face some challenges in 2019: some cost inflation to mitigate and the risk of a churn increase following December’s outage although experience suggests this is likely to be short-lived.
 

Vodafone’s revenue trends took another step backwards this quarter (down almost 3% on our estimates) with its strongest markets (UK and Germany) weakening unexpectedly

The reiteration of their financial guidance and commitment to cost-reduction provides some reassurance although nothing in the results provides grounds for optimism; churn is not really falling and is not correlated to convergence

With the UK mobile market delivering its strongest growth in 7 years last quarter, these results may be a precursor for a more challenging outlook with Vodafone citing pressure from business pricing and out-of-bundle limits, and the outlook for RPI-linked price increases diminishing
