Management Commentary

  • “We achieved an all‑time high for quarterly revenue, adjusted EBITDA, and AFFO driven by strength across our business.” — CEO William L. Meaney .
  • “We are capitalizing on robust data center industry demand… we have high confidence in sustaining our data center revenue growth… underwritten by our pre‑leasing backlog, strong pipeline, as well as 450 megawatts… to be energized over the next 18–24 months.” — CEO .
  • “Adjusted EBITDA was an all‑time record… up $92 million, or 16% year‑on‑year… $10 million ahead of the projection we provided on our last call, driven by operational strength and productivity.” — CFO Barry Hytinen .
  • On the Treasury contract: “It will be linear with slight growth… there is a seasonality aspect with tax season… we’ve begun staffing and clearance to be ready for spring 2026.” — CEO .

Q&A Highlights

  • Treasury digitization contract (up to $714M/5 years): revenue will be seasonal (tax season), with ramp beginning into 2026; outcome range depends on volumes and form mix .
  • ALM dynamics: enterprise‑led growth with profitability expansion; some component pricing tailwinds (memory/HDD) but vary by part; expecting strong Q4 organic growth again .
  • Data center pipeline: hyperscalers refocusing on inference/cloud buildouts; 250MW energizing next 18 months (450MW over 24 months); 2026+ growth visibility solid, including London/Virginia/Madrid/Miami .
  • RIM outlook: continued mid‑single‑digit revenue management, low churn, improving retention; FX a sequential headwind embedded in Q4 guidance .

Estimates Context

  • Revenue: $1.754B actual vs $1.753B consensus* — slight beat. Values retrieved from S&P Global.*
  • Adjusted EPS: $0.54 actual vs $0.53 consensus* — beat by ~$0.01. Values retrieved from S&P Global.*
  • Street likely to lift FY Adj. EPS/AFFO per share modestly given Q3 upside and stronger Q4 run‑rate implied by commencements and reiterated guide .

Key Takeaways for Investors

  • Mix shift supports premium multiple: Data center (52.6% margin) and ALM are driving two‑thirds of consolidated growth and expanding margins; this underpins medium‑term double‑digit EBITDA growth .
  • Dividend growth is sustainable: low‑60s AFFO payout ratio and reiterated FY AFFO guide, plus balance sheet at 5.0x within target, support ongoing returns .
  • Near‑term catalysts: Q4 commencements (36MW) and leasing updates; further proof points on DXP/Treasury execution and enterprise ALM wins .
  • Watch GAAP noise: FX on intercompany balances and higher interest expense can obscure strong underlying cash/Adj. metrics; focus on Adj. EBITDA/AFFO trajectory .
  • Capex intensity remains high but pre‑leased: development is heavily pre‑leased to high‑credit hyperscalers, de‑risking returns across 1.3GW roadmap .
  • RIM durability intact: rising utilization and retention >93% with consistent revenue management continue to fund growth and stabilize cycles .
  • Risk checks: power cost pass‑through dynamics (non‑profit generating on power revenue), development execution/timing, and component pricing volatility within ALM .
