I’ll try to keep this post as short as possible, so I’ll just give you the big picture of the company. Cellnex is a “TowerCo,” similar to AMT (American Tower Corp), and it is the largest player in Europe.
What is a TowerCo? Simply put, they manage the infrastructure that allows you to have mobile data. They are not telcos (like Verizon, AT&T, or T-Mobile); instead, they own the towers themselves, the physical metal infrastructure. The MNOs (like Verizon, AT&T, or T-Mobile) own and operate the antennas in the tower.
**You might ask: what makes TowerCos attractive?**
**Depreciation vs. Maintenance Capex:**
Although assets are depreciated over roughly 20 years for accounting purposes, the physical infrastructure remains useful for much longer. As a result, depreciation is largely an accounting adjustment rather than a true reflection of ongoing maintenance costs.
**High Margins:**
Consequently, RLFCF margins (free cash flow after leases, interest, and maintenance capex) are around 45%.
**Long-term Contracts:**
Cellnex holds long-term contracts with an average duration of 20 years, linked to inflation (65% CPI-linked and 35% with fixed annual escalators of 1–2%).
**Why is Cellnex an opportunity right now?:**
Essentially, because its current committed capex makes it appear as though the company has no free cash flow. However, these commitments will gradually decline through 2025–2029 until they become residual. At that point, roughly 60% of RLFCF should surface (in addition to other, non-committed expansion capex that might be dedicated to buybacks).
**A Brief History of the Company:**
Cellnex emerged during the boom of the European TowerCo sector around 2013. For years, it pursued aggressive growth by acquiring as many towers as possible through debt and equity dilution, eventually becoming the largest player in Europe.
Starting in 2021, as interest rates began to rise, the company was forced to pivot from “growth mode” to “harvest mode.”
In 2023, Chris Hohn (a quality-focused investor with \~20% annualized returns) acquired a 10% stake and reshaped the board. The new strategy is straightforward: allow free cash flow to materialize and then return it to shareholders through buybacks and dividends.
**Valuation:**
To regain investment-grade ratings from Fitch and S&P, the company sold assets, notably its operations in Austria and Ireland, at 20–24x EBITDA. Meanwhile, Cellnex itself trades at roughly 12x EBITDA and at a \~10% RLFCF yield. The company can grow top-line organically at 3–5% while growing the bottom line at 6–9%.
**Why the market isn’t noticing:**
This is probably the core issue of the thesis: nothing meaningful is likely to happen over the next 2–5 years. Even though the company has started share buybacks and initiated a dividend with the cash flow that is beginning to emerge, these are not perceived as strong catalysts.
For example, JPMorgan cut its price target from €44 (with the stock trading at €26) to €31, simply because analysts tend to anchor their price targets to where they expect the stock to trade over the following year. They explicitly stated that “there will be no positive catalysts,” and in the short term, they are right.
The key point is that over a 2–5 year horizon, either the company will massively shrink its share count through buybacks or the market will re-rate the business, but this will unfold over a very long time horizon.
**Debt, organic growth, and threats:**
You might be alarmed when you see debt at 6.4x EBITDA, but this is normal in this sector. They have 20 years of guaranteed free cash flow and are backed by physical assets. You don’t have to take my word for it, just look at the bond market:
Risk-free yield (German 5- and 10-year bonds): \~2.42% and \~2.82%
Cellnex refinancing (January 2026)
5-year bond: 3.000%
10-year bond: 3.875%
Spreads: 58 bps and 105 bps, respectively
As you can see, the bond market clearly views this as a safe investment.
**Threats**
There are two main ones:
**Low Earth Orbit (LEO) satellites (SpaceX and AST SpaceMobile).**
I mention this mainly to address concerns rather than as a real risk. None of the companies involved, ASTS, SpaceX, the telcos themselves, or the tower companies, see satellites as a viable replacement for towers. This is even less of a threat to Cellnex in Europe, which is a much denser continent compared to North America or Africa. Satellites tend to make sense only where building a tower was never economical in the first place.
**Consolidation of MNOs (the European equivalents of Verizon, AT&T, and T-Mobile).**
The European market is far more fragmented (typically 2–4 players per country), and consolidation might appear to be a risk, but it really isn’t:
1. Regulators will not allow consolidation beyond a certain point.
1. Regulators are forcing 5G investment as a condition for consolidation.
1. Real case: this has already happened in Spain. The result? Cellnex renegotiated the agreement (allowing the removal of 3,000 redundant antennas) in exchange for an extension of the contract until 2048, with the same annual value (simply shifted into the future, which is irrelevant since it is CPI-linked), and compensated by higher investment in 5G.
**Organic growth****:**
Their costs are entirely fixed. In other words, a tower can host up to three antennas, but the costs are the same whether there are one, two, or three antennas from other MNOs. Part of the value comes from this (which implies operating leverage), through what are known as co-locations, i.e. adding another MNO’s antenna to the same tower.
On the other hand, 5G investment in Europe lags significantly behind China and the US. The growth in mobile data usage and AI will require greater investment to support higher network capacity, densification, and performance.
Overall, organic topline growth is expected to be modest, around 3–5%, while bottom-line growth should be higher, in the range of 6–9%.
That’s about it. There are more things to cover, but this is the basic investment thesis. I’m happy to answer any questions you may have.
