Key takeaway

Digital Realty is buying African interconnection it already part-owns while US data-centre sites stall on tax and hardware.

Digital Realty raised its stake in Teraco, Africa's largest data-centre platform, from about 61% to 77% on 22 June, paying roughly $650m through new shares⁠¹. The same announcement added Columbia Capital, a US digital-infrastructure investor, for about $485m, and a $475m land parcel in Kansas City for a new hyperscale campus. Teraco runs the leading interconnect campuses in South Africa, Nigeria and Kenya, where regional networks physically meet.

Digital Realty is a real estate investment trust (REIT), a listed company that owns and leases data-centre property at scale. By raising the Teraco stake it is buying interconnection it already part-owns rather than joining the queue for constrained Western capacity, a contrast with Equinix, whose 3 GW pipeline sits in the same crowded US and European metros.

The money is going deeper into a frontier market precisely as US campuses stall on tax and transformer waits. Digital Realty is paying for reach rather than cheap power: Teraco's campuses are the points where South African, Nigerian and Kenyan carrier networks interconnect, and that position is hard to replicate and slow for a rival to build from scratch.

Deep Analysis

In plain English

Digital Realty is one of the world's largest data-centre companies, listed on the US stock market. Teraco is Africa's biggest data-centre and internet-exchange business, operating in South Africa, Nigeria, and Kenya. An internet exchange is a physical location where different internet networks connect to each other; whoever operates the exchange charges a fee for those connections. Digital Realty already owned 61% of Teraco. On 22 June it bought more shares to raise that to 77%, paying about $650m. In the same announcement it bought Columbia Capital, a US digital-infrastructure investment firm, for $485m, and bought land in Kansas City for a new large campus at a cost of $475m. The three moves together show Digital Realty building a position in markets where power and planning capacity is still available, since its existing facilities in constrained markets like Northern Virginia and Silicon Valley have a 3 GW pipeline that is already tight.

What could happen next?

Precedent
Digital Realty's 77% Teraco stake is the largest Western data-centre REIT holding in sub-Saharan Africa and signals that African internet-exchange infrastructure has reached the valuation threshold at which global institutional capital treats it as core infrastructure rather than emerging-market risk.
Consequence
Retaining the remaining 23% with Permira rather than moving to 100% suggests Digital Realty is managing South African regulatory exposure; a future move to full ownership will require ICASA clearance and potentially local-content commitments.

Source Landscape

This story draws on neutral-leaning sources

Primary parallel: Equinix's 2020 acquisition of a majority stake in MainOne, West Africa's submarine cable and data-centre operator, for $320m established the first major Western data-centre REIT stake in sub-Saharan Africa. Equinix subsequently consolidated to full ownership by 2022 after carrier-neutral interconnection demand exceeded MainOne's capacity and further expansion required strategic control.

Digital Realty's move from 61% to 77% in Teraco follows an identical trajectory: a minority stake that worked operationally is being converted to controlling-majority ahead of a Teraco capacity expansion that requires Digital Realty's balance sheet.

Counter-parallel: In contrast to the Equinix-MainOne path, Digital Realty has not moved to 100% ownership, leaving the remaining 23% of Teraco with the existing shareholders including Permira.

This restraint may reflect regulatory sensitivity: full foreign ownership of dominant telecom-interconnection infrastructure in South Africa requires sign-off from the Independent Communications Authority of South Africa (ICASA), which has previously conditioned such approvals on local-content requirements that could constrain operating margins.

Digital Realty's three-move announcement on 22 June totals approximately $1.6bn in capital deployment: $650m for the Teraco stake increase, $485m for Columbia Capital, and $475m for the Kansas City land parcel.

At Digital Realty's current enterprise value of roughly $50bn, this represents a 3% total capital deployment in a single announcement, signalling that Africa and secondary US markets are now valued at comparable opportunity to the hyperscale cluster markets (Northern Virginia, Silicon Valley) where Digital Realty's existing 3 GW pipeline is constrained.

Raising Teraco's stake from 61% to 77% for $650m implies a Teraco enterprise value of roughly $4.1bn, approximately 28x the 2025 EBITDA of $145m that Teraco has disclosed publicly.

That multiple is at the top of emerging-market infrastructure valuations, reflecting the scarcity value of Teraco's carrier-neutral interconnection position in South Africa: Teraco operates the dominant internet exchange point for sub-Saharan Africa, meaning any operator wanting low-latency African connectivity pays Teraco a recurring cross-connect fee that is essentially a toll on African internet traffic.

Different Perspectives

Chilean data-centre developers

Seven projects, one linked to Google, asked SEA this month for rulings that they fall outside full environmental review; four declared diesel-storage volumes just under the review-triggering tonnage, mirroring the mechanism Alto Jahuel used in July. The clustering suggests the threshold is being engineered, not sized to need.

An Coimisiun Pleanala

Ireland's planning appeals body refused the €1.5bn Killala data centre on 17 September, overturning Mayo County Council's 2025 grant for lack of a fixed grid-connection agreement and no corporate renewable power-purchase agreement. The ruling makes matched-power evidence, not planning consent alone, the deciding factor.

Housing Assembly and Foxglove

The two groups' 6 August appeal, filed through the Legal Resources Centre, kept Cape Town's approval of Equinix's data centre suspended through this window over missing water, emissions, noise and diesel-generator data. Deputy Mayor Eddie Andrews confirmed on 20-21 September that the suspension holds.

Brazil (President Lula, signing Redata)

Lula signed Lei 15.504 on 15 September, creating the Redata tax programme and keeping the Senate's water cap with no veto, while Aneel authorised Scala's AI City to join the national grid from January 2028. Brazil is recruiting capacity other markets are now turning away.

Aragon regional government (Eva Valle)

Aragon's economy chief Eva Valle said on 11 September that Spain's draft decree, requiring 80% hourly-matched renewables via a 10-year power-purchase agreement, is unmeetable by any project and threatens Blackstone, Azora and Microsoft builds already under way. Aragon holds 3,600 MW of granted grid access against 108 MW built.

Texas Governor Greg Abbott

Abbott ordered TCEQ on 21 September to halt every pending data-centre permit until projects pay their own way and complete ERCOT and Texas Water Development Board audits. Texas built the country's most permissive data-centre market; freezing it signals even that market has hit its grid limit.
