Vantage Towers, which owns 68,000 masts across nine European countries, is eyeing a spring listing in Frankfurt that would arm CEO Vivek Badrinath with the firepower to pay for takeovers with its own shares.

In an interview, Badrinath said his primary focus would be to strengthen Vantage's position in existing markets. But the former Orange executive also acknowledged interest expressed by the French operator in possible towers cooperation.

Europe lagged the United States by 20 years in reshaping its industry to split infrastructure from mobile operators, with just 42% of its towers run by specialist companies compared to 90% in the United States.

"There is 10 years of growth ahead," Badrinath said. "So it's a good time to build, structure, strengthen and invest."

Vodafone, Europe's largest mobile player with 116 million customers, is the first big operator to float a towerco and hopes that Vantage could fetch a market valuation of more than 18 billion euros (16.5 billion pounds).

Because towers generate long-term revenue streams that are tied to inflation and expected to grow as new 5G networks expand, they are gaining favour as an asset class in a world of low investment returns.

They can also support high debt - Vantage targets a leverage ratio of four times and says it has 'headroom' of a further 1 billion euros to do deals.

Spain's Cellnex is already rolling up regional tower assets in deals backed by debt and equity issuance, recently buying 24,000 towers from Hong Kong's CK Hutchison for 10 billion euros.

FILL-IN ACQUISITIONS

Badrinath said his plan did not require mergers and acquisitions to work out, but added: "If we want to do something bigger because it appears, that's something we would look at."

He would be interested in fill-in acquisitions in the markets where Vantage is already either the number one or number two player.

Badrinath would also consider bigger deals to go 'off footprint' into new markets. He noted Orange CEO Stephane Richard's recent comments to the Financial Times that the French group was open to towers cooperation, while adding that no talks were taking place.

Relations with Deutsche Telekom's towers unit were also good in Germany, Vantage's largest market and where the company is headquartered.

Vantage is still working to fold CTIL, its UK joint venture with Telefonica's O2, into the business, said Badrinath: "I am optimistic of getting it in the right time frame. But it's not done until it's done."
