# Sharing the burden: tower sales and network partnerships
A carrier owns roughly 15,000 cell towers. On paper they are assets. In practice they are a drag: steel, concrete, land leases, diesel generators, and maintenance crews that soak up capital while earning a thin, boring return. So the carrier sells them to a specialist for cash, then rents them back. Overnight, billions move off the balance sheet and the company promises to keep paying rent for the next 15 years.
This is one of the most common financial maneuvers in modern telecom. Let us model exactly what happens to the numbers.
A tower is passive infrastructure. It does not differentiate one carrier from another. Customers pick a network for coverage and speed, not for who owns the steel.
Owning towers ties up capital that could fund spectrum (the licensed radio frequencies carriers use, bought at auction for billions) or 5G equipment. It also means the carrier carries the maintenance burden alone, even though a single tower can physically host antennas from three or four operators.
Enter the TowerCo: a company whose entire business is owning towers and renting space on them to multiple tenants. Its economics improve with every additional tenant, because the cost of the tower is largely fixed. A tower with three tenants earns roughly three rents against one set of costs. That is why TowerCos trade at higher valuation multiples than carriers.
Large independent TowerCos like American Tower, Cellnex in Europe, and Indus Towers in India built entire businesses on this logic.
A sale-and-leaseback is exactly what it sounds like: you sell an asset and immediately sign a lease to keep using it.
Here is our hypothetical carrier, "Meridian Mobile," spinning its towers into a wholly owned or joint-venture TowerCo, then either selling a stake or the whole thing.
Meridian moves its 15,000 towers into a subsidiary. Say the towers have a book value (the accounting value on the balance sheet) of 3 billion. An independent TowerCo values them higher, because it can add tenants Meridian never could. Suppose a buyer pays 6 billion.
Meridian receives 6 billion in cash. It books a gain versus book value. That cash typically goes to three places: paying down debt, funding 5G capital expenditurecapital expenditureCapital Expenditure (CapEx) is money spent to acquire, upgrade, or extend long-lived assets like equipment, property, or software that deliver value over multiple years.View full definition →, or returning money to shareholders through buybacks or dividends.
Meridian now signs a Master Lease Agreement (MLA): a long-term contract, often 10 to 15 years, committing it to pay rent per tower per year. This rent is the catch. Illustratively, if annual rent is 400 million, Meridian has swapped a one-time 6 billion inflow for a stream of fixed, contractual outflows.
The International Finance Corporation's primer on infrastructure finance is a useful free background read on how these long-lived asset structures are financed.
This is where finance students should slow down, because the accounting has a twist.
Before 2019, an operating lease stayed off the balance sheet entirely. You sold the tower, took the cash, and the rent was just an expense. Balance sheet looked much lighter. That was the whole appeal.
Then IFRS 16 (the international lease accounting standard) and the equivalent US standard ASC 842 changed the rules. Now almost every lease must appear on the balance sheet as:
So Meridian sells 6 billion of towers, but then books a multi-billion lease liability for the rent it owes. The balance sheet does not shrink as dramatically as it once did.
Three reasons survive the accounting change:
1. Cash is real. The 6 billion is genuine liquidity, usable today to cut expensive debt or fund the network.
2. Risk transfer. The TowerCo now owns the maintenance, the land lease renewals, and the obsolescence risk.
3. Multiple arbitrage. The market values tower cash flows more highly inside a TowerCo than inside a carrier. Separating them can unlock value even if the consolidated balance sheet looks similar.

Here is the trap that catches unwary analysts.
Before the sale, tower costs showed up as depreciation (spreading the tower's cost over its life) and maintenance. After the sale, under IFRS 16, the rent is split into depreciation of the right-of-use asset plus interest on the lease liability.
The effect: EBITDA looks better.

This is why serious telecom analysts watch EBITDA after leases (EBITDAaL), a metric that subtracts lease costs back out. It gives a truer picture.

Selling towers is passive sharing. The next move is active sharing of the network itself.
The RAN (Radio Access Network) is the active electronic gear: the antennas, radios, and baseband units that actually send and receive signals. It is expensive to build and maintain, especially for nationwide 5G.
Two carriers can share this in two ways:
RAN sharing sits in tension with competition law. If two of a country's three carriers share their entire network, are they still real competitors? Regulators (the government bodies overseeing telecom, such as Ofcom in the UK or the FCC in the US) often permit passive sharing readily but scrutinize active sharing, sometimes requiring carriers to keep spectrum and core networks separate.
The UK's "Beacon" arrangement between Vodafone and O2, and the "MBNL" arrangement between EE and Three, are real, long-running examples of network sharing joint ventures.
Active RAN sharing can meaningfully reduce network capital expenditurecapital expenditureCapital Expenditure (CapEx) is money spent to acquire, upgrade, or extend long-lived assets like equipment, property, or software that deliver value over multiple years.View full definition → and ongoing operating cost, because two carriers split the bill for one set of radios. Commonly cited estimates suggest active sharing can cut relevant network costs by a double-digit percentage, though the exact figure depends heavily on geography and deal terms.

After both moves, Meridian Mobile looks structurally different:
The strategic logic: telecom is becoming a business of spectrum and software, not steel. Carriers increasingly want to own what differentiates them and rent or share what does not.
Fixed obligations are safe in good times and dangerous in bad ones. A carrier that has sold its towers and locked into 15-year escalating rents has less flexibility if revenue falls. The buyer captured real value too; these deals are priced by sophisticated parties. There is no free money, only a reshaping of who bears which risk.
