- Global RIM: Revenue grew 6.3% to $5.29 billion; Adjusted EBITDA margin improved 10 basis points to 44.7%.
- Global Data Center: Revenue surged 29.6% to $803.4 million due to lease commencements and improved pricing; Adjusted EBITDA margin expanded 620 basis points to 51.8%.

Guidance, Outlook, and Risks
- Outlook: Management expects continued total revenue and Adjusted EBITDA growth in 2026, driven by new product offerings, cross-selling, and market expansion. Organic storage rental revenue growth is expected to be driven by revenue management in Global RIM and lease commencements in Data Centers.
- Capital Expenditures: Total capital expenditures for 2026 are expected to be approximately $2.2 billion, with $2.05 billion allocated to growth investments (primarily data centers) and $150 million to recurring expenditures.
- Dividends: The company declared a quarterly dividend of $0.8640 per share in February 2026. As a REIT, the company is required to distribute at least 90% of taxable income.
- Key Risks:
- Cybersecurity: Attacks on IT systems could damage reputation and operations; the company maintains a robust NIST-based security program.
- REIT Qualification: Failure to maintain REIT status would subject the company to corporate income tax rates.
- Indebtedness: High leverage limits flexibility and increases interest expense sensitivity to rate hikes.
- Technology Shifts: Customer migration from physical records to digital storage could impact traditional storage volumes.
- Geopolitical/Currency: Operations in 61 countries expose the company to currency fluctuations and geopolitical instability.
Investor Verification Checklist
- Debt Covenants: Verify compliance with the net total lease adjusted leverage ratio (4.9x actual vs. 7.0x max) and fixed charge coverage ratio (2.5x actual vs. 1.5x min).
- Foreign Currency Impact: Assess the sustainability of operations given the $105.6 million foreign currency transaction loss in 2025 and the company's hedging strategies.
- Data Center Utilization: Confirm the 97% lease-up rate of existing 488 MW capacity and the timeline for revenue recognition on the 852 MW under construction.
- Project Matterhorn ROI: Monitor the realization of cost synergies and revenue growth following the completion of the $574.4 million transformation program.
- Goodwill Impairment: Review the Asset Lifecycle Management (ALM) reporting unit, which held $780.3 million in goodwill and was tested for impairment with a 93.7% excess fair value margin.
