The company reported 4Q25 revenue of $1.6 billion (+14% year-over-year) and Core FFO of $1.86 per share (Constant-Currency Core FFO: $1.81), alongside renewal cash spreads of 6.1% (12.0% on a GAAP basis). Digital Realty ended 2025 with $817 million of annualized GAAP base rent backlog at its share, and it introduced 2026 Core FFO guidance of $7.90–$8.00 per share on both a reported and constant-currency basis.
Operationally, Digital Realty emphasized capacity expansion and booking momentum tied to cloud and AI demand. The earnings presentation cites ~3 GW of in-place IT capacity, 769 MW under construction, 90 MW delivered in 4Q25, and 135 MW of net new starts in the quarter, plus “>5 GW” of future development capacity.

🌐 Analysis: Digital Realty’s emphasis on smaller-to-midscale deployments (0–1 MW) plus interconnection aligns with the architecture shift toward distributed AI inference, enterprise private AI, and hybrid connectivity patterns that pull more cross-connect density into colocation hubs. The backlog and multi-year capacity pipeline suggest operators will keep prioritizing power-and-land control and faster delivery cycles as hyperscalers and large enterprises compete for constrained grid capacity in key metros.
