Digital Realty (DLR) Q4 2025 earnings review
Record High-Margin Bookings Drive Acceleration into 2026
Digital Realty ended FY25 with robust momentum, delivering 14% YoY revenue growth and record bookings in its high-margin '0-1 MW plus Interconnection' segment ($96 million). While Core FFO per share dipped slightly sequentially to $1.86 (from $1.89), it grew 7.5% YoY. Management introduced strong FY26 guidance with a Core FFO midpoint of $7.95, implying continued ~7.5% growth, supported by a substantial $817 million backlog and favorable pricing dynamics.
🐂 Bull Case
The '0-1 MW + Interconnection' segment hit a record $96 million in bookings (DLR share), accelerating from $85 million in Q3 and $76 million a year ago. This enterprise-focused segment typically commands higher yields than hyperscale deals.
Renewal spreads remain healthy at +6.1% on a cash basis (+12.0% GAAP). With occupancy ticking up to 84.7% and supply remaining constrained in key power-starved markets, pricing leverage remains with the landlord.
🐻 Bear Case
The backlog of signed-but-not-commenced leases declined sequentially for the second quarter, dropping to $817 million from $852 million in Q3 and $919 million in Q1. While still high historically, the downward trend suggests commencements are outpacing new hyperscale signings.
The 2026 outlook calls for $3.25-$3.75 billion in development CapEx. With net debt-to-Adjusted EBITDA at 4.9x and significant debt maturities managed via refinancing at higher rates (e.g., replacing 2.5% notes with ~4% notes), capital costs remain a headwind.
⚖️ Verdict: 🟢
Bullish. The strategic pivot to the 0-1 MW segment is paying off with record results, diversifying the revenue mix away from lumpy hyperscale deals. The 2026 guidance floor of $7.90 suggests confidence in the ~7-8% growth algorithm despite interest rate headwinds.
Key Themes
Enterprise & Interconnection Strength
The '0-1 MW plus Interconnection' category is becoming the primary growth engine. Bookings reached a record $96 million (DLR share) in Q4, comprised of $77 million in 0-1 MW and $19 million in interconnection. This segment grew consistently throughout 2025, validating the 'full spectrum' strategy.
Debt Refinancing Headwinds
Interest expense rose to $116.5 million in Q4 from $104.7 million a year ago. The company repaid €1.075 billion of 2.500% notes early but issued €1.4 billion of new notes at significantly higher rates (3.750% and 4.250%). This 'repricing' of the debt stack creates a drag on FFO growth despite strong operational NOI.
Backlog Visibility
Despite a sequential dip, the $817 million backlog provides immense revenue visibility for 2026. The lag between signing and commencement averaged 8 months in Q4. This backlog supports the 2026 revenue guidance of $6.6-$6.7 billion.
Private Capital Strategy Maturation
DLR continues to leverage private capital to fund growth without blowing out leverage. In Q4, they contributed an incremental 40% interest in 5 data centers to a fund, raising $427 million. They also formed a JV in Israel. This 'capital recycling' is essential to fund the $3.5B+ annual capex requirement.
Hyperscale Lumpiness
While the 0-1 MW segment surged, the >1 MW segment (hyperscale) bookings were $65 million (DLR share), down from $76 million in Q3 and $172 million in Q1. This highlights the inherent lumpiness of large-deal signings, contributing to the sequential decline in the total backlog.
Other KPIs
Decelerating sequentially (-1% QoQ) but strong YoY (+14%). The sequential dip contrasts with the revenue growth, potentially driven by transaction/integration expenses which spiked to $36M in Q4.
Stable/Decelerating. Down from $1.89 in Q3 but up from $1.73 in 24Q4. FY25 total was $7.39, beating the original guidance and landing just above the high end of the Q3 updated guidance range ($7.32-$7.38).
Stable. Effectively flat vs Q3 (84.8%) and up from 84.1% a year ago. Management guides for +50-100 bps improvement in 2026.
Guidance
Accelerating/Stable. The midpoint ($7.95) represents ~7.6% growth over FY25's $7.39. This maintains the high-single-digit growth trajectory established in 2025.
Accelerating. Implies ~9% YoY growth at the midpoint vs FY25 revenue of $6.11 billion. Supported by backlog conversion and renewal pricing.
Accelerating. Midpoint ($3.65B) implies ~10.6% growth over FY25's $3.30B, suggesting margin expansion.
Stable. The range centers around the 7% mark, consistent with the 6.1% achieved in 25Q4 and 7.3% in 25Q2, indicating continued pricing power.
Key Questions
Backlog Erosion Trend
The backlog has declined for two consecutive quarters ($919M -> $852M -> $817M). Is this purely a function of faster commencements, or are hyperscale signings slowing down due to power constraints or digestion?
Hyperscale vs. Enterprise Mix
With record 0-1MW bookings but lighter >1MW activity in Q4, is the company strategically pivoting away from hyperscale deals, or is this just quarterly lumpiness? How does this mix shift impact development yields?
Transaction Expenses
Transaction and integration expenses were $36M in Q4 and $185M for the full year. What constitutes these ongoing high costs, and should we expect this run-rate to continue into 2026?
