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
