The Robeco Gravis Digital Infrastructure Income strategy offers pure exposure to the most valuable physical assets that sustain the world of AI, ecommerce, gaming and social media, including data centers, communications towers and logistics hubs through a portfolio of listed securities. It is managed by a London-based team at Gravis, a boutique asset manager that specializes in real estate, infrastructure and clean energy. The new strategy shines a light on an under-invested real estate segment that is underpinned by the same mega trends driving investment in technology platforms, says Norris.
“The world has changed: the way we work, the way we shop, the way we play. And now everything is stored in the cloud. Humankind back in 2010 had created only one zettabyte of data. But then, explosive growth in social media and streaming came along and by 2020 we were at 60 zettabytes,” he says.

This has created demand for more and more data center capacity. “Tech platforms need this capacity in proximity to big populations, so they either build it themselves or rent it. But it’s becoming much harder to build due to the constraints on power supply and access to the hyper fast fiber optic networks, so the existing companies in this space are very well placed”, says Norris.
The same dynamic is driving the slow but steady rollout of 5G infrastructure worldwide, says Norris. “The acceleration in demand for data is staggering“ he says, pointing to the adoption cycle of novel platforms with ChatGPT reaching 100 million users in only two months1.

This places owners of telecommunications infrastructure in a sweet spot, says Norris. “With the towers, we invest in concrete and steel owners. When you get a tenant on it and the tenant is a mobile network operator, you have a profitable tower. And when they want to upgrade to 5G that just adds more dishes, which adds more rent,” he says.
This “picks and shovels” approach avoids many of the pitfalls of conventional commercial property investment. “There are no legacy buildings and there’s little exposure to the tech cycle. We own the space, not the servers or the dishes on towers, or the robotics in a logistics center. Even the electricity is almost always a pass-through cost.”
He says large tech platforms also invest in their own infrastructure but, because of the need for proximity to customers and limitations on new developments, they also rent space from the existing owners of data center sites and logistics facilities, where the requisite power access and fiber networks are already in place. “Some of the cloud providers are competitors to the companies we (the Robeco Gravis Digital Infrastructure strategy) own, but they are almost always customers too, renting prime space on long leases.”
Norris says the positive outlook for digital infrastructure is validated by the private equity activity in recent years, attracted by the same balance of reliable income and potential growth. “The difference with our strategy is that it’s a diverse set of best in class investments across the whole space, whereas investing via a private equity route you are probably exposed to more concentration in terms of specific assets, and thus more risk.” The strategy only invests in developed markets and uses a bottom-up fundamental approach to stock selection. In February 2024, it is composed of 28 different investments from a potential universe of more 80 listed entities that fit the investment criteria and sustainability requirements.
“We have a quality bias and very low churn rate, below 10%, and this helps us find that balance of regular income and capital appreciation,” he says. The strategy pays a quarterly dividend. “The businesses we focus on are regular dividend payers with next generation assets and that defensive nature is valuable in this environment” he says.

Norris underscores sustainability is part of the portfolio construction process. More than half of the portfolio must consist of sustainable investments making a positive contribution to the UN SDGs under the Robeco SDG Framework2. Moreover, the strategy is classified as Article 8 under SFDR. “In February 2024 that measure is at 65%. Best in class data center operators, like the companies we invest in, are trying to source more power from renewables while also improving their power usage efficiency.”
The strategy will vote in line with Robeco’s Engagement Policy and Proxy Voting Policy included in Robeco’s Stewardship Policy, and follow the Robeco exclusion policy.
