European mobile service revenue growth worsened slightly in Q2, dropping to -1.2% after three consecutive quarters at -0.8%. Southern Europe significantly outperformed the North, reversing the regional trend of recent years

EU roaming rate cuts and the increase in SIM-only subscriptions were the two main negative, albeit temporary, factors with the former particularly impacting northern European operators with heavy roaming exposure and the latter more varied in its impact across the EU5

Mobile service revenue growth was thus quite robust given these factors, helped by price firming in a number of markets. Looking forward, while the negative factors are likely to continue in the short-term they will drop out in two years in the case of roaming cuts, and SIM-only, whose impact is mostly profit-neutral to operators, will also reach an equilibrium in due course, and the market's overall resilience is encouraging

European mobile service revenue growth was flat at -0.8%, while underlying country movements were somewhat more dramatic. The key highlights were Italy returning to positive growth driven by pricing stability, and France showing worsening growth decline for the first time in over two years impacted by challenger telco pricing cuts

An assessment of these challenger telcos highlights a somewhat precarious position, as continued price aggression yields diminishing incremental gains, and they all remain some way from gaining the scale to achieve profitability

The only incentive for challengers to remain aggressive is as an encouragement for their competitors to buy them; increasing regulatory hurdles to consolidation would remove even this incentive, leaving price increases as their only rational route to profitability

T-Mobile and Orange’s plan to merge their UK businesses into a JV would create the UK’s largest mobile operator by some margin, and the enormous planned synergies of £545m per annum are actually quite unaggressive given the cost overlap

This achievement would be moderated by ‘integration leakage’, i.e. increased churn caused by customers leaving who were initially attracted by an aspect of one of the operators that disappears after integration, but the net result should still be positive for the JV

The remaining UK operators will benefit both from this churn and the reduction in competitive intensity associated with five players dropping to four. While all the operators may win, UK consumers might lose, with regulatory clearance thus still far from certain

Vodafone (and others) are reported to be interested in acquiring T-Mobile in the UK, but any such merger would be likely to face significant barriers from regulatory authorities

The planned merger of Vodafone and H3G in Australia has raised the question of what consolidation could occur in Europe, although a direct analogy is not appropriate because Vodafone is much weaker in Australia (#3 operator) than it is in the larger European countries, and so would face much more regulatory scrutiny in Europe

The only merger opportunities in the top five markets which would have a similar or lower theoretical impact on competition (and hence would theoretically be as easily approved) in the top five European countries would be T-Mobile and H3G in the UK, Wind and H3G in Italy, and any operator with Yoigo in Spain

There are massive cost savings to be had from in-market consolidation, with network, marketing and general administration costs all fully overlapping between operators. The non-merging players would also enjoy a period of less competitive intensity, which may last indefinitely
