DLR · Q4 2025 Earnings

Digital Realty

Reported February 5, 2026

30-second summary

SENTIMENT: Constructive Digital Realty closed FY2025 with $6.11B revenue (+10.1% YoY, above the raised $6.025–$6.075B band) and Core FFO/share of $7.39, just above the high end of the raised $7.32–$7.38 guide and +10% YoY. Constant-Currency Core FFO/share of $7.29 landed inside the raised $7.25–$7.30 band. Q4 bookings of $175M at DLR share ($400M at 100% share), record backlog of $1.4B at 100% share ($817M at DLR share), and 84.7% occupancy keep the demand story intact. The FY2026 Core FFO guide of $7.90–$8.00 implies +6.9% to +8.3% YoY off the $7.39 base (midpoint ~8%, as management framed it); management adds that on a normalized/constant-currency basis they "anticipate total revenue and adjusted EBITDA growth of more than 10% in 2026."

Management tone

Narrative arc: Record 0-1MW mix → Backlog-driven raises → Connectivity moat and verbal 10% commit → Power scarcity codified as durable moat.

The most material multi-quarter shift is from "power as constraint" to "power as the defining structural moat." Two quarters ago power was framed as alignment risk on late-2026/2027 deliveries; last quarter it became "harder to build in these locations for a growing list of reasons"; this quarter management codifies it: "power became the industry's primary constraint…customers are prioritizing operators with verified visibility into the future supply of power and a track record of on-time or even accelerated delivery." That is the language of pricing power as a permanent moat, not a cyclical advantage.

The AI narrative has compressed from "future opportunity" to "scheduled inflection." Q2 framed enterprise AI as "patient" and "modest"; Q3 made the metro-inference thesis explicit; this quarter management puts inference on the 12-month calendar: "With inference expected to scale in 2026, we see continued expansion of these private AI exchange use cases as a durable driver of interconnection demand." Inference is no longer a TAM story — it is a 2026 revenue lever. The signal is that interconnection growth (already +9.8% YoY this quarter, with bookings up 22% YoY for the segment) should accelerate, not decelerate, into the FY2026 guide.

Customer diversity has been promoted from anecdote to streak. Last quarter management cited "seven consecutive quarters where our largest signing is from a different hyperscaler." This quarter, that streak extends to "seven straight consecutive quarters" — and the framing pivots from defensive (rebutting concentration-risk objections) to offensive (evidence of breadth of demand). The fact that this is now a recurring talking point suggests management views customer diversity as the second leg of the moat alongside power.

On near-term visibility, management is shifting the disclosure lens. Beginning next quarter, occupancy and other key metrics will be reported on an IT load basis rather than square feet — same-capital occupancy on IT load is ~91% and total portfolio ~89%, both up 50+ bps YoY. This reframes a metric that has looked flat on the square-foot basis into a more flattering trajectory and aligns reporting with how the business is now managed. Combined with the "more than 10% normalized" framing on FY2026 growth, the tone is confident but increasingly reliant on adjusted/normalized presentations to fully telegraph the underlying momentum.

Recurring themes management leaned on this quarter:

Power as primary constraint and competitive moatInference workloads scaling in 2026 as durable demand driverDiversity of hyperscaler demand across geographies and customer baseEnterprise AI adoption and 5-15 MW contiguous block emergencePrivate capital strategy enabling competitive funding advantageInterconnection and network effects as core differentiation

Risks management surfaced:

Labor and supply chain tightness impacting build costs and timelinesIndustry-wide nimbyism and regulatory pushback on data centers affecting grid relianceCompetitive capacity supply arriving in 2027-2028Fixed-rate renewals in greater-than-megawatt portfolio limiting escalation upsideCurrency headwinds (160 bps interest expense increase from euro bond redemption)

Answers to last quarter's watch list

Backlog progression toward $900M+. DLR-share backlog declined to $817M from prior quarter levels as $209M of commencements outpaced $175M of new signings — but total backlog at 100% share reached a record ~$1.4B, which management explicitly elevated as "a better representation." Bookings of $175M DLR share / $400M at 100% share were strong. Status: Resolved positively on aggregate basis; mixed on DLR-share trajectory
Q4 cash renewal spreads versus the raised +5.75–6.25% band. Cash spreads printed +6.1%, landing inside the raised band. FY2025 cash spreads of +6.7% surpassed the high end of guidance. The FY2026 guide of +6–8% effectively brackets the Q4 print.
Resolved positively
Initial 2026 guidance vs the verbal 10% commitment. The printed FY2026 revenue guide of $6.60–$6.70B implies +8.0–9.7% YoY off the $6.11B base. Core FFO of $7.90–$8.00 implies +6.9–8.3% (midpoint ~8%). Management's "more than 10%" framing applies on a normalized/constant-currency basis. The reported-basis math sits below the verbal trajectory, though the higher FY2025 base (vs original Feb-2025 guide ~500bps below) absorbs some of that gap.
Continue monitoring
2026 CapEx guidance vs the $3.0B FY2025 actual. Net development CapEx guided to $3.25–$3.75B, a step-up of roughly $500M at the midpoint, consistent with management's commitment to lean into the runway. The dispositions/JV capital line of $500M–$1B confirms private-capital recycling will offset balance-sheet strain — particularly with the $3.225B closed-end fund now essentially fully raised.
Resolved positively
Occupancy trajectory from 84.8%. Square-foot occupancy ticked down 10bps to 84.7%, but management is transitioning disclosure to IT load basis where total portfolio is ~89% (up 50+ bps YoY). The FY2026 guide of +50–100bps on the IT load metric signals continued improvement. Status: Resolved positively under the new framework

What to watch into next quarter

Q1 bookings and the DLR-share vs 100%-share backlog gap — with management explicitly elevating the 100%-share view, watch whether DLR-share backlog rebuilds from $817M or whether the gap widens further as private-capital partners absorb more of the development pipeline

Whether management can reconcile the "more than 10% normalized" prepared-remarks framing with the printed +8% midpoint — either via a Q1 guide raise or via clearer constant-currency vs reported bridging

Q1 cash renewal spreads — FY2025 printed +6.7%; the +6–8% FY2026 band brackets that, but watch whether the mix of 0-1MW (lower spreads) vs >1MW (8.1% in Q4) shifts the print toward the high or low end

Inference-driven interconnection growth — management explicitly committed to inference scaling in 2026 and interconnection bookings stepped up 22% YoY in 2H25; watch whether interconnection & other revenue accelerates from the current +9.8% YoY

The IT-load occupancy disclosure transition — first full quarter under the new framework will set the baseline for the +50–100bps FY2026 commitment

Labor and supply chain pressure — management called labor "getting challenging more challenging by the day"; watch whether development yields hold at the 10%+ guide and whether the 160bps euro bond refi headwind shows up cleanly in Q1 interest expense
