Zegona plots an exit from all 7,500 Vantage masts — €60m a year at stake, with BlackRock and KKR on the other side of the table

The Hispano-Luso Report

A quiet war is being fought over the Spanish airwaves… On one side: Vodafone España, controlled since 2024 by London-listed Zegona. On the other: Vantage Towers Spain — the mast company Vodafone itself created — and, standing behind it, two of the largest infrastructure investors on earth: BlackRock’s GIP and KKR.

The prize, per Expansión’s reporting from sources close to the process: Vodafone España intends to replace its principal tower supplier entirely — walking away from all of the roughly 7,500 sites Vantage provides — by migrating its network onto rivals’ masts. The savings target: cutting a €135 million annual tower bill by 45%, to around €75 million. Sixty million euros a year, every year, for a company whose new owner’s investment case is built on exactly this kind of surgery.

The revolt, in two contracts

The escape plan is already being executed in public, if you know what you’re reading. On 3 July, Cellnex announced a renewed agreement with Vodafone España: ten more years on the roughly 2,000 sites where Vodafone’s radios already sit — plus, buried in the extension, new Cellnex sites (fewer than 500, per sources) that will serve zones currently covered from Vantage masts.

Days later, per Expansión, came the bigger move: a 15-year agreement with American Tower Corporation — the world’s largest tower company, and since its acquisition of Telefónica’s masts, Spain’s biggest too, with more than 12,100 sites. ATC renewed the ~1,000 towers already serving Vodafone and extended the deal to roughly 2,000 additional sites earmarked to replace Vantage locations.

Add it up: some 5,500 towers now secured long-term with Vantage’s rivals. Between them, ATC and Cellnex operate more than 20,000 Spanish sites — capacity, Vodafone believes, to absorb most of the migration, with regional operators filling the gaps. The contracts are reportedly structured with minimum commitments and room to expand: an escape hatch built in stages.

Why the rent is so high — and why it’s so hard to cut

The economics underneath deserve a paragraph, because they explain every tower dispute in Europe. When telecoms operators sold their masts during the infrastructure gold rush, they extracted top prices from buyers — and the buyers’ maths only worked because the seller signed on as «anchor tenant» at premium rents, long-term. Spain hosted the era’s flagship deal: Telefónica’s Telxius selling some 31,000 towers to American Tower for €7.7 billion in 2021 — the same vehicle whose remaining subsea-cable business this Report covered being marketed to global buyers in our first edition. Vantage was born the same way: spun out of Vodafone, with GIP and KKR paying for 50% (via the Oak Holdings vehicle, alongside Vodafone Group’s retained half) at a valuation built on those contracted Spanish cash flows.

While Vodafone España sat inside the Vodafone family, the above-market rent was an internal transfer — nobody minded. The moment Zegona took the keys, it became a target. Zegona has spent two years demanding Vantage reprice to market. Vantage has not moved — and arguably cannot: a unilateral discount to its Spanish anchor tenant would detonate the assumptions its own shareholders paid for. BlackRock and KKR did not buy tower cash flows to watch them be renegotiated downward.

Hence the contractual trench warfare. Vodafone’s contract contains an exit window in November 2028 — notice already served, back in 2024 — but with an all-or-nothing clause standard in the industry: leave, and you must leave every site at once. That is Vantage’s armour. Migrating thousands of radio installations is slow, expensive and risky for coverage quality, and a few hundred strategic sites — built bespoke for major corporate and state clients — may have no practical substitute. The simplest outcome for everyone remains the one that hasn’t happened: Vantage blinks, cuts the rent, and the revolt is called off.

The chess move nobody’s pricing

Here is the layer that makes this more than a procurement dispute — and it concerns the most-discussed non-deal in Spanish telecoms: a Telefónica takeover of Vodafone España.

Network savings are among the biggest synergies in any telecoms merger: combine two operators, decommission one set of radios. But every tower Vodafone signs onto for 10 or 15 years is a tower its radios contractually cannot leave — meaning each of these agreements shrinks the network synergies a buyer could extract. The fixed-line version already happened: Vodafone’s 2.6 million broadband customers were transferred into the PremiumFiber joint venture with Masorange, effectively locked to that network for 28 years. If the ATC and Cellnex agreements expand to cover all 7,500 Vantage sites, the mobile version follows.

Read cynically — and this Report is paid to — Zegona is doing two things with one signature: cutting €60 million from its costs and dismantling the synergy case that would let Telefónica buy Vodafone España cheaply. A seller who reduces the buyer’s synergies isn’t sabotaging a sale; it’s negotiating the price early. Though one caveat cuts the other way: Telefónica is itself a major client of both ATC and Cellnex — contracts between friends can be rearranged.

What to watch

Three markers. Whether the ATC and Cellnex agreements expand toward full Vantage replacement — the signal that the revolt is real rather than leverage. Whether Vantage offers the discount that ends it. And November 2028, the all-or-nothing door. Between now and then, every tower contract signed in Spain is also a sentence in the negotiation over what Vodafone España is worth — and to whom.
