Digital Realty Pays $3.5B to Blackstone for Virginia Data Center Stakes in Share-Heavy Deal

Digital Realty paid $3.5 billion to Blackstone for the private equity firm's 64 percent blended equity interest in three Northern Virginia data centers, closing a transaction structured as $2.3 billion in Digital Realty shares and $1.2 billion in cash. The assets sit in Ashburn, the densest data center corridor in North America, where availability for hyperscale and AI training capacity has compressed below 4 percent over the past eighteen months.

The deal consolidates Digital Realty's ownership in facilities it already operated as minority partner. Blackstone acquired the stakes through its 2019 purchase of a QTS Realty portfolio and its 2023 investment in Digital Realty's own development ventures. The transaction removes Blackstone from the cap table while leaving Digital Realty with full control over expansion timelines, tenant negotiations, and power procurement — critical levers as Northern Virginia's Dominion Energy grid faces allocation constraints that now push new capacity delivery windows past 2027 in some submarkets.

The $2.3 billion equity component dilutes existing Digital Realty shareholders by roughly 3.8 percent at current valuations, a structure that preserves balance sheet flexibility while signaling the REIT's reluctance to tap unsecured debt markets where investment-grade data center paper currently prices above 5.4 percent for ten-year money. Blackstone exits with liquid shares in a company trading near $172 per share, up 19 percent year-over-year, and avoids the mark-to-market complexity of holding illiquid stakes in assets now worth materially more than 2019 basis.

Northern Virginia remains the global epicenter for hyperscale deployment. Microsoft, Amazon Web Services, and Google collectively lease over 11 million square feet of data center space within a fifteen-mile radius of Ashburn, with Oracle and Meta adding another 2.6 million square feet under contract or in build-out. AI inference workloads — which demand lower latency and higher interconnection density than training clusters — are migrating toward these edge-adjacent hubs, where fiber routes terminate and peering costs collapse. Digital Realty's full ownership eliminates the governance friction that delayed two previous expansion phases at the acquired sites, where Blackstone's infrastructure fund mandates required quarterly return hurdles incompatible with speculative power reservations.

The transaction also clarifies Digital Realty's capital allocation posture heading into a year where data center REITs face $47 billion in aggregate refinancing across the sector. The company now owns outright the Virginia assets generating approximately $340 million in annualized NOI, based on disclosed occupancy and prevailing Northern Virginia lease rates of $185 per kilowatt per month. That income funds additional development without pro-rata distribution obligations to a minority partner, particularly relevant as Digital Realty has 1.2 gigawatts of expansion capacity queued across its Northern Virginia land bank.

Allocators should track Digital Realty's first earnings call post-close, expected mid-February, for updated guidance on FFO accretion and any announced pre-leasing commitments tied to the expanded capacity. Dominion Energy's April 2025 resource adequacy filing will clarify whether additional generation comes online in time to support builds scheduled for late 2026 delivery. Blackstone's liquidity event may also pressure peers still holding minority stakes in co-investment structures — particularly Equinix and CyrusOne vehicles where private capital partners face similar mark-to-market inflection points.

Digital Realty now controls the expansion pace at three facilities sitting on 180 acres with utilities infrastructure already permitted for 420 megawatts of additional IT load, a development pipeline worth roughly $2.8 billion at replacement cost in today's Northern Virginia construction environment.
