Digital Realty (DLR) Q1 2026 earnings review
Record Leasing Masks Decelerating Renewal Spreads and Rising Build Costs
Digital Realty delivered a blockbuster first quarter of 2026, highlighted by the largest hyperscale lease in company history. Total operating revenue reached $1.64B (up 16% YoY) and Core FFO surged 15% YoY to $2.04 per share, driving a full-year guidance raise. The company recorded a staggering $423M in DLR-share bookings, obliterating prior run rates and swelling the DLR-share backlog to $1.0B. However, beneath the explosive volume growth lies a margin friction point: cash renewal spreads are decelerating, and development CapEx guidance was hiked by $250M at the midpoint as labor and infrastructure costs escalate.
🐂 Bull Case
Total backlog (100% share) sits at a record $1.8 billion, with DLR-share bookings accelerating violently to $423M in the quarter. The 'largest lease in history' secures massive forward cash flows.
Despite a massive $3.5B+ capital deployment pipeline, DLR drove Net Debt to Adjusted EBITDA down to 4.7x (from 5.1x a year ago), utilizing robust ATM equity issuance ($1.3B in Q1) to fund growth efficiently.
🐻 Bear Case
Cash renewal spreads decelerated to 5.0% from 6.1% in Q4 and 8.0% in Q3. This directly contradicts the prevailing narrative of infinite pricing leverage in a supply-constrained market.
Development CapEx guidance was raised by $250 million on the lower and upper bounds. The race to scale AI infrastructure is resulting in elevated labor, materials, and power grid access costs.
⚖️ Verdict: 🟢
Bullish. The absolute volume of the hyperscale demand pipeline and the successful defense of the balance sheet—improving leverage metrics while absorbing massive CapEx—outweighs the near-term margin headwinds from build inflation and moderating renewal spreads.
Key Themes
AI Inference Driving Hyperscale Breakout
Accelerating. Hyperscale demand is driving an outright explosion in bookings. DLR-share bookings printed at $423M in Q1, a massive leap from the ~$135M to $242M quarterly range seen throughout 2025. This was anchored by the largest single hyperscale lease in company history, validating the thesis that mixed-density AI inference workloads are moving toward connected metro environments rather than remaining isolated in remote training campuses.
Decelerating Re-leasing Spreads
Decelerating. A notable data point contradicting the 'unlimited pricing power' narrative: cash rental rates on renewal leases increased by only 5.0% in 26Q1. This represents a sequential deceleration from 6.1% in 25Q4, and a stark drop from the 8.0% peak achieved in 25Q3. While management previously blamed segment mix (0-1MW vs >1MW), the persistent downward trajectory warrants close monitoring.
0-1 MW & Interconnection Segment Resilience
Stable. The enterprise-focused 0-1 megawatt plus interconnection segment contributed $98M in Q1 at DLR's share. This is higher than the $90M record celebrated in 25Q2, proving that enterprise digital transformation and hybrid cloud adoption provide a consistent, high-margin, fast-turnaround secondary engine underneath the lumpy hyperscale business.
Rising CapEx and Macro Strain
Accelerating. The cost of growth is getting steeper. Management raised FY26 Development CapEx guidance to $3.5B - $4.0B (up from initial $3.25B - $3.75B). This reflects the macro reality of labor shortages, supply chain inflation, and the costs associated with upgrading facilities for high-density liquid cooling. Furthermore, management explicitly acknowledged growing NIMBYism and grid strain in Tier-1 metros, which threatens development timelines.
Capital Formation and Deleveraging
Accelerating. Rather than blowing out leverage to fund this CapEx supercycle, DLR is tapping alternative capital. The company issued 7.3 million shares via its ATM program in Q1 for $1.3B, maintaining a pristine 4.7x Net Debt-to-Adjusted EBITDA ratio. Combining public equity with their U.S. Hyperscale Data Center Fund allows DLR to capture unprecedented demand without endangering the balance sheet.
Interest Expense Headwinds Persist
Stable. Despite falling base rates, the refinancing of low-coupon legacy debt continues to bleed cash. DLR retired €1.075 billion in 2.5% debt in late 2025, replacing it with higher-yielding green bonds. Total interest expense remained high at $116.4M in 26Q1, actively pressuring bottom-line GAAP profitability even as Core FFO expands.
Other KPIs
Accelerating. The backlog of signed-but-not-commenced leases spiked from $817M in Q4 2025 to $1.0B in Q1 2026. This guarantees significant, locked-in revenue growth stretching into late 2026 and 2027 as these facilities come online.
Accelerating improvement. Down from 4.9x in Q4 2025 and 5.1x a year ago (Q1 2025). Achieving this level of deleveraging while simultaneous printing $400M+ in quarterly bookings and hiking development CapEx is a masterclass in capital allocation.
Guidance
Accelerating. Upward revision from the initial $7.90 - $8.00 guide. The midpoint ($8.05) implies roughly 8.9% growth over FY25's actual $7.39, signaling strong conviction in flow-through from recent hyperscale deals.
Accelerating. Raised by $50M from prior guidance. The midpoint ($6.70B) implies a healthy +10.3% YoY growth vs FY25, supported by the massive $1B active DLR-share backlog.
Accelerating. Increased by $250M at the midpoint. While necessary to fulfill the record pipeline, this highlights the immense capital intensity required to play in the AI infrastructure space.
Key Questions
Margin Friction in Re-leasing
Cash renewal spreads have decelerated for two consecutive quarters, hitting 5.0% in Q1. Is this entirely a function of 0-1MW vs >1MW mix, or are hyperscale clients demanding better pricing on legacy renewals in exchange for signing massive new footprint deals?
CapEx vs Return Profile
With development CapEx guidance raised by $250M, how are escalating labor and power equipment costs impacting your expected stabilized yields? Are you able to pass 100% of these cost inflations through to the customer in the initial lease rate?
AI Inference vs Training Split
The record hyperscale lease was a major win. Roughly what percentage of your forward pipeline is now explicitly geared toward AI inference deployments in metro markets vs traditional cloud availability zone expansion?
NIMBYism and Delivery Timelines
You acknowledged growing community pushback and grid strain. Are you seeing measurable delays in permitting or power delivery for your 2026/2027 pipeline, and does the $1.0B backlog carry penalty risks for delayed commencement?
