Helios Towers Hits 8% Revenue Growth in 2025

Africa is about to add a billion people. This isn't a distant abstraction — it's the demographic reality shaping every infrastructure investment decision on the continent right now. For Helios Towers, it's the tailwind behind a 2025 performance that quietly tells a more interesting story than the headline numbers suggest.

The company posted 8% revenue growth for the full 2025 financial year, driven not by building more towers, but by filling the ones it already has. That distinction matters enormously in the tower business.

The Numbers Behind the Growth

Helios operates close to 15,000 towers across nine African markets — Tanzania, DRC, Congo Brazzaville, Ghana, South Africa, Senegal, Madagascar, and Malawi. In 2025, it added 2,538 net new tenants, bringing its total tenant count to 31,944, a 9% increase year-over-year.

The real story isn't tenant volume — it's what those tenants cost Helios to acquire. Most of them came through colocation: mobile network operators adding equipment to existing structures rather than demanding new builds. This keeps capital expenditure contained while revenue scales.

CEO Tom Greenwood noted that the company achieved its 2.2x tenancy ratio target a full year ahead of schedule. One year early is worth pausing on. In infrastructure development — where timelines routinely slip — hitting a major strategic milestone early signals genuine operational tightening, not just favorable market conditions.

Why Tenancy Ratios Are the Real Scorecard

For anyone unfamiliar with tower economics, the tenancy ratio is the number of paying tenants per tower. A tower with one tenant covers its operating costs and little else. Add a second tenant, and you've dramatically improved the unit economics because the fixed costs — land lease, power, maintenance, security — don't double. Add a third, and the margin expansion is substantial.

Helios moved its ratio from 2.05 to 2.17 in a single year. That 0.12 improvement across nearly 15,000 towers translates to meaningful incremental revenue with minimal incremental cost. This is the core engine of towerco profitability, and Helios is running it well.

CFO Manish Dhillon put it plainly at MWC 2026 in Barcelona: "No towerco really wants to build for one tenant, and no MNO will arguably want that either, because it's the highest cost to do so. If you're looking to maximize that fixed cost, you want to maximize multiple companies."

That's not just a talking point — it's the structural reason why colocation strategies dominate every serious towerco's growth playbook.

Impact 2030: Betting on 5G and a Bigger Continent

Helios' new five-year strategy, Impact 2030, has a clear numerical target: push the tenancy ratio to 2.5 by 2030. From 2.17 today, that's a 0.33 improvement over five years — achievable, but it requires consistent execution across nine distinct regulatory and competitive environments.

The strategy rests on two pillars. First, 5G densification. Greenwood was candid during the earnings call: most of Helios' markets have been in a 4G buildout phase, with some markets still completing that cycle. 5G changes the physics of the business. Higher frequency bands require more antenna sites, which means mobile operators need more tower space — and more colocation opportunities for Helios.

"Some of the markets have now started 5G, and the ones that haven't, we expect to probably in the next two years," Greenwood said. "A big part of that is the 5G cycle for most of our markets, which we're really excited about, and we're already working with our key customers in terms of planning that."

The insider reality here: 5G densification in African markets will look different from what happened in the US or Europe. Urban centers in Lagos, Nairobi, Kinshasa, and Accra will see significant activity, but rural coverage — where much of Africa's population growth will concentrate — will depend heavily on whether operators can justify the economics. That's where the colocation model becomes not just attractive but essential. Shared infrastructure lowers the cost-per-covered-population enough to make rural 5G commercially viable in ways standalone builds simply can't.

Africa's Population Boom Is the Long Runway

Africa's current population sits just under 1.6 billion. By 2050, UN projections put that number at approximately 2.5 billion — nearly a billion new potential mobile subscribers over 25 years. Dhillon made the business case at MWC: "Those people will want to be connected and want to use mobile, and so that means your addressable market is always growing. You need to develop the infrastructure and the networks to make sure you can facilitate that."

This demographic argument is real, but it comes with important nuance. Population growth doesn't automatically translate to ARPU growth. Many of the markets Helios serves have low average revenue per user, which constrains how aggressively mobile operators invest in network expansion. The colocation model partially solves this by spreading the infrastructure cost across multiple operators — making it viable to build where a single-tenant model would stall.

Helios is also looking at AI-enabled site management as part of its forward strategy. Dhillon flagged the use of climate data across the tower portfolio to monitor weather conditions — wind loads, flooding risk — in real time. At scale across 15,000 sites in geographically diverse markets, that kind of predictive maintenance capability isn't just operational efficiency. It's a competitive differentiator when pitching to MNO customers who need guaranteed uptime.

Where Helios Goes From Here

One notable signal from the earnings call: M&A is off the table as a near-term priority. After an acquisition-heavy run in recent years — which is how Helios built its nine-market footprint — the company is now in execution mode. Dhillon was direct: "M&A is lower down in the priority rankings. We don't need to do M&A to get growth. We have more than enough of it in our markets."

That's a disciplined position for a company that could easily justify expansion into new markets given its operational track record. It also suggests Helios believes the organic opportunity in its existing portfolio is large enough to absorb capital and management attention through 2030 without chasing new geographies.

The path from 2.17 to 2.5 tenants per tower won't be linear. 5G rollout timelines in Africa will be uneven, regulatory environments will create friction in some markets, and currency dynamics across nine countries add complexity to any revenue forecast. But the structural thesis — more people, more devices, shared infrastructure, fixed-cost leverage — is as durable as infrastructure economics get.

Helios hit its last target a year early. The market will be watching to see if Impact 2030 runs on the same clock.
