BlackRock and IFM Enter Exclusive Talks for $25 Billion Stack APAC Data Center Portfolio

A consortium anchored by BlackRock and IFM Investors has entered exclusive negotiations to acquire Stack Infrastructure's Asia Pacific data center portfolio in a transaction valued at $25 billion. The deal, if closed, would represent one of the largest infrastructure acquisitions in the region this cycle and extends BlackRock's positioning in AI-adjacent real assets across high-growth compute markets.

Stack Infrastructure operates hyperscale data center facilities in Singapore, Tokyo, Seoul, and Sydney—markets where cloud service providers and AI labs are competing for scarce co-location capacity and power allocations. The APAC portfolio includes 14 operational facilities and six development sites, with aggregate IT load capacity exceeding 1.2 gigawatts once build-outs complete. Stack's customer base skews toward Tier 1 cloud providers under long-term contracts, with average remaining lease durations near 9.4 years and embedded annual escalators tied to local CPI or power costs. Exclusivity typically runs 60 to 90 days; sources familiar expect a definitive agreement before year-end if diligence confirms power supply commitments and development timelines.

The move matters because it signals infrastructure allocators are underwriting AI compute demand as secular rather than cyclical. BlackRock has deployed over $40 billion into digital infrastructure since 2021, including its $12.5 billion acquisition of Global Infrastructure Partners earlier this year, which held data center stakes across North America and Europe. IFM, the Melbourne-based pension fund manager with $200 billion under management, has been rotating out of toll roads and airports into power-intensive assets where contracts price in electricity pass-throughs. The Stack portfolio offers both: long-duration leases and exposure to markets where power costs are rising faster than legacy infrastructure can absorb. Singapore's land scarcity and Japan's nuclear restart timeline create supply constraints that keep utilization rates above 95 percent even as new capacity comes online.

Second-order effects warrant attention. If the consortium closes, it removes a consolidation target from the market and likely resets private-market valuation multiples for data center assets with contracted hyperscale tenants. Recent transactions in the sector have priced at 16 to 22 times forward EBITDA, depending on lease duration and power reliability. At $25 billion, the Stack APAC deal implies a multiple near the top of that range, assuming Stack's reported $1.4 billion in regional EBITDA. That sets a floor for competing portfolios in Southeast Asia and Australia, where DigitalBridge, Equinix, and smaller operators are evaluating sale processes. Allocators who missed earlier data center cycles may face steeper entry costs or longer development timelines if existing capacity gets locked into single-buyer portfolios.

Operators and allocators should watch three markers. First, whether the consortium secures binding commitments from local utilities for incremental power capacity at the six development sites; without firm allocations, those sites remain land plays rather than operating assets. Second, how quickly Stack's U.S. and European operations come to market; the parent company's shareholders, including private equity sponsors, may seek liquidity across all geographies if the APAC sale closes at favorable terms. Third, whether sovereign wealth funds in the Middle East or Asia counter-bid during exclusivity; Abu Dhabi's Mubadala and Singapore's GIC have both increased digital infrastructure allocations this year and may view the portfolio as strategic. Any competing offer would likely need to clear $27 billion to break exclusivity.

BlackRock's infrastructure desk now manages over $55 billion in hard assets, with data centers comprising nearly 40 percent of deployed capital. The Stack acquisition, if finalized, pushes that concentration past the threshold where sector-specific risk becomes portfolio-level risk—particularly if power costs or utilization rates move against underwriting assumptions in a synchronized slowdown.
