Keppel DC REIT and Keppel Ltd Buy 90% of Two Tokyo Data Centres in $1.2 Bn Deal

Keppel DC REIT and its sponsor, Singapore-based Keppel Ltd, have agreed to acquire a 90% effective interest in two hyperscale data centres in Greater Tokyo for JPY190 Bn ($1.2 Bn). The transaction deepens the Singapore-listed entities’ exposure to Japan, where a severely constrained power grid is rapidly driving up the premium for operational digital infrastructure.

The deal spans Tokyo Data Centre 4 and Tokyo Data Centre 5, both located in the technology hub of Inzai City. Keppel DC REIT will hold an 88.62% effective stake in each facility, while Keppel Ltd will hold 1.38% via its local subsidiary, Keppel Japan KK. The existing global operator will retain the remaining 10% to ensure management continuity and aligned economic interests.

The transaction is slated for completion in the fourth quarter of 2026.

The co-investment should make the deal an interested person transaction under SGX rules, given Keppel Ltd’s control over the entity that runs the real estate investment trust. The same classification was applied last year when the two entities jointly acquired Tokyo Data Centre 3.

The JPY190 Bn headline price reflects the assets’ 100% valuation and represents a 2.1% discount to their JPY194 Bn appraised value. Keppel DC REIT’s share of the purchase consideration amounts to approximately JPY168.4 Bn (S$1.37 Bn).

The trust intends to bankroll the buyout through a mix of new equity and yen-denominated debt. It plans to raise at least S$600 Mn via a private placement of new units priced between S$2.096 and S$2.142 each, with issuance slated for September 10. The final placement price had not been set as of September 1.

The management expects the acquisition to be immediately accretive to distribution per unit (DPU). On a pro forma basis, had the transaction closed on January 1, 2025, FY25 DPU would have risen 2.6% to 10.649 Singapore cents, up from 10.381 cents.

The two freehold, fully fitted colocation facilities are 100% occupied by four investment-grade internet enterprise and IT services clients, three of which are entirely new tenants for the REIT. While contracted rents include an annual escalation clause averaging 2.8%, the manager estimates that current passing rents sit at least 30% below prevailing market rates.

The combination of full occupancy and significantly under-rented assets supports the transaction’s core commercial logic and positions it for substantial organic revenue growth upon lease renewals.

Buying What Is Hard to Build

The primary constraint shaping Tokyo’s data centre economics is access to grid power availability, not a lack of demand.

Tokyo’s data centre inventory surpassed 1 GW in the first quarter of 2026. Yet vacancy rates compressed to 6% despite substantial capacity additions over the previous 12 months, according to CBRE data. The real estate advisor points to power availability as the single largest bottleneck for future pipeline development, even as hyperscale cloud adoption and artificial intelligence deployments accelerate.

This power crunch is acutely visible in Inzai, the Chiba Prefecture technology cluster where Keppel’s targeted assets sit. Property consultancy JLL notes that planned power capacity across parts of Greater Tokyo is already heavily allocated, with Inzai facing strict grid constraints heading towards 2030 despite slated substation expansions. Consequently, operational sites with secured electricity supply are commanding a steep valuation premium.

These supply dynamics shift the financial calculation of buying operational data centres over greenfield development.

While new construction projects offer potential development upside, they require sourcing scarce land, securing grid connections, deploying upfront capital and waiting years for initial cash flows. In contrast, Keppel is acquiring two fully baked assets with power access, operational infrastructure and a steady stream of paying tenants already locked in.

The transaction allows the trust to expand its footprint in Asia’s top digital market while sidestepping the severe execution and timeline risks of ground-up construction.

Under-Rented Leases Lock In Organic Growth

The transaction’s structural upside is embedded in the asset lease profiles. Tokyo Data Centre 4 has a weighted average lease expiry (WALE) of about 4.5 years, while Tokyo Data Centre 5 has a longer runway of 10.6 years. This staggered maturity gives the trust a dual advantage: stable, long-term income visibility from one asset and near-term exposure to lease expirations at the other, where rents can be marked to market.

This staggered structure is highly lucrative given that Keppel estimates the assets’ current passing rents sit at least 30% below prevailing market rates.

To be sure, this reversionary potential does not guarantee future windfall profits. Actual rental spikes will hinge strictly on the timing of contract expirations, tenant renewal negotiations and broader macroeconomic conditions at the point of reset.

However, the steep rental discount provides a clear path to earnings growth without expanding physical capacity. The trust is securing a defensive baseline of contracted income and embedded 2.8% annual escalations, coupled with a highly asymmetric call option on Tokyo’s market rents as leases roll over.

This intrinsic organic upside clarifies the transaction’s funding math, specifically how Keppel DC REIT can execute an equity issue of roughly 11% of its unit base via its S$600 Mn placement and still deliver immediate, pro forma DPU accretion to unitholders.

Japan Moves From Diversification to Core Market

The transaction reshapes Keppel DC REIT’s geographic footprint, establishing Japan as a cornerstone market. Its assets under management are set to reach about S$7.6 Bn from S$6.3 Bn, expanding the portfolio by nearly a fifth in a single transaction. Japan’s contribution to the portfolio’s rental income will surge to roughly 23% from just 9% as of June 30, positioning the country as the trust’s second-largest market behind Singapore, which retains a dominant 60% share.

This expansion comes as Keppel recalibrates its data centre exposure elsewhere in Asia. In Indonesia, Salim Group recently bought out Keppel’s stake in their former IndoKeppel joint venture, taking full ownership of the business now operating as IndoData.

The pivot into Japan has occurred at a rapid clip. Keppel DC REIT only entered the country in 2024, closing its JPY82.1 Bn acquisition of Tokyo Data Centre 3, also located in Inzai, in November 2025. This latest transaction significantly advances that strategy.

The geographic concentration aligns with broader market realities. Greater Tokyo and Greater Osaka together command roughly 90% of Japan’s total data centre capacity, according to JLL. Keppel describes Japan as the largest data centre hub in Asia Pacific excluding China. The property consultancy expects accelerating AI utilisation to intensify pressure on power grids even as new developments attempt to come online.

For Keppel, doubling down on Japan presents a clear trade-off. It maximises exposure to a market where secular demand and grid constraints should defend asset valuations and rental growth. But it also makes the trust more dependent on Japan performing exactly as expected.

The acquisition will also diversify Keppel DC REIT’s tenant base. Three of the four customers at the two Tokyo data centres are new to the portfolio, reducing the REIT’s dependence on its largest client. That client’s share of total rental income is expected to fall to around 38.2% from 43.5% after the deal is completed.

Why Fresh Equity Is Necessary

Keppel DC REIT enters the transaction with a relatively clean balance sheet. Aggregate leverage stood at 34% as of June 30, and its first-half cost of debt was a modest 2.6%.

However, the trust’s debt headroom relative to the manager’s internal 40% leverage threshold was approximately S$673 Mn, less than half of the S$1.37 Bn required for its share of the acquisition. Fully debt-funding the transaction within that self-imposed limit was mathematically impossible. Doing so would also have devoured a large portion of the roughly S$2.1 Bn in absolute headroom available before hitting the regulatory ceiling of 50%.

Consequently, the private placement serves a more immediate purpose than merely preserving financial flexibility. It provides the core capital required for the transaction without pushing the trust towards leverage boundaries that management deliberately seeks to avoid.

Pairing this newly raised equity with yen-denominated debt also creates a natural balance sheet hedge against currency fluctuations, aligning the funding liabilities with the rental income generated by the Japanese assets.

Yet the decision to issue equity carries an inherent friction. Expanding the unit base dilutes existing unitholders unless the newly acquired earnings can outpace the expanded share count.

This dynamic is why management’s pro forma DPU accretion figure of 2.6% is the fundamental pillar of the transaction’s investment case. It indicates that the asset bundle—with its full occupancy, built-in rental escalations and baseline yields—is robust enough to override the dilutive impact of the equity issuance, provided the underlying projections hold.

Ultimately, Keppel is asking its investor base to co-fund a significantly larger operational footprint in Japan, using equity to keep the trust’s risk profile firmly within its conservative leverage boundaries.

This Deal Is Really About Scarcity

The acquisition comes against the inevitable backdrop of the artificial intelligence boom, but secular AI demand alone does not explain why Keppel is paying $1.2 Bn for two existing facilities. Data centre demand can spike exponentially and still yield poor investment returns if supply scales fast enough to match it.

Tokyo’s structural reality is different. Real estate advisor CBRE identifies power availability as the principal bottleneck to new development, noting that available capacity across major Asia-Pacific digital hubs plunged 43% YoY in the first quarter of 2026 to just 248.4 MW, with any space coming online being aggressively absorbed. With Tokyo’s vacancy rate compressed to 6%, existing powered capacity has become exceptionally difficult to replicate at short notice.

Consequently, Keppel is not just buying immediate contracted revenue and future rental reversion; it is buying infrastructure whose most critical and elusive input—electricity—is already locked in.

But the transaction case is not without friction. Management’s 30% discount estimate may not fully materialise into future rent hikes, financing costs remain exposed to macroeconomic shifts and a significantly larger footprint in Japan introduces geographic concentration risk.

However, the investment thesis does not require every hyperbolic AI demand forecast to come true. Keppel is securing operational infrastructure in a market protected by high barriers to entry, where competing supply cannot easily be added and where passing rents have significant headroom.

This makes the deal less of a speculative wager on headline AI growth, and more of a structural play on the exact asset AI is making scarce—data centre capacity that is already powered, occupied, and nearly impossible to reproduce.
