Vodafone and H3G have finally announced their long-trailed merger plans, with weaker-than-expected financials and the focus squarely on the superiority of a combined network.

We view the hailed synergy estimates of £700m per year as achievable but the merged entity will need to deliver other positive financial filips to get returns above its cost of capital.

The approval case for the merger is that: it makes the operators a stronger competitive force; prices won't rise; a combined network will be superior, and that the status quo is unsustainable in any case.

The combination of 5G, AI, IoT and big data were evangelised at MWC as generating massive scope for the transformation of multiple industries. 

That much is probably true, but it is the tech and consultancy companies who will likely receive the benefits, with connectivity revenue likely to be modest.

For the operators, 5G brings more capacity much needed for hungry smartphone users, and perhaps the opportunity to transform themselves into a leaner operating model.
