Cellnex Telecom: Still A Strong Buy Despite Higher Interest Rates

This is less a classic growth rerate than a duration trade with equity optionality. The core value driver is that contractual indexation keeps nominal cash flow from eroding, but the stock will only compound if financing costs stop outrunning that indexation; in other words, the spread between asset cash yield and debt cost matters more than headline revenue growth. The immediate reaction can linger for days, but the real catalyst path is 1-3 months: credit spreads, ECB rate expectations, and whether management can show the next refinancing window is absorbable without equity leakage.

The second-order winner is the tower/infrastructure complex; the second-order loser is the mobile operator tenant base. Indexed rents look benign in inflationary models, but they transfer margin pressure onto telecom operators, which can show up later as slower network spend, tougher renewal negotiations, or more aggressive sharing arrangements. That caps long-term tenancy growth, so the thesis is defensive rather than cyclical: the business can defend cash flow, but not necessarily accelerate it.

Contrarian view: the market may be overstating CPI linkage as a free hedge. If euro inflation keeps normalizing, reported growth decelerates while legacy higher coupons remain fixed, which can make leverage optics worse before per-share cash flow inflects. The thesis breaks if 2025 guidance is trimmed, refinancing spreads widen again, or asset sales become necessary to bridge maturities; those are the key falsifiers over 6-18 months.
