Empire State Realty OP, L.P. 2025 Annual Report: Key Insights for Investors

Overview and Business Model

Empire State Realty OP, L.P. (the “Operating Partnership”) is the operating entity for Empire State Realty Trust, Inc., with a primary focus on owning, managing, operating, acquiring, repositioning, and disposing of office, retail, and multifamily properties—principally in New York City. The report covers the fiscal year ended December 31, 2025.

Key Highlights

• Strong Market Position and Tenant Demand: The company is benefiting from a “tenant flight to quality” trend as tenants seek landlords with robust balance sheets, low leverage, and a track record of investing in building improvements. The firm positions itself as a high-quality asset provider, offering compelling value and a strong tenant experience. This has led to high tenant retention, with 317 tenant expansions totaling 3.2 million square feet since the IPO.
• Well-Positioned Balance Sheet: The company’s financial strength differentiates it among brokers and tenants, allowing it to recycle and deploy capital efficiently. This financial flexibility is especially crucial in the current economic environment and may position the firm to capitalize on acquisition opportunities or weather market volatility.
• Focus on Sustainability and Energy Efficiency: Empire State Realty OP is recognized as a leader in sustainability, focusing on energy efficiency, emissions reduction, water use, waste reduction, indoor environmental quality, and healthy buildings. The company has published its “Empire Building Playbook” in partnership with NYSERDA and the Clinton Global Initiative, providing a technical and economic pathway for energy savings and emissions reductions. These initiatives reduce costs and may enhance the company’s competitive positioning.
• Revenue Streams: The firm derives most of its revenue from rents, rent escalations, tenant reimbursements, and other income from existing leases. Notably, the company believes that in-place lease rates are generally below current market rates, suggesting potential for future rental income growth as leases roll over.
• Business Segments: The company reports two segments: real estate (office, retail, and multifamily assets) and the Observatory segment (operating the 86th and 102nd floor observatories at the Empire State Building). This provides both stable rental income and tourism-driven revenue.
• Legal and Environmental Risk: The company emphasizes ongoing compliance with the Americans with Disabilities Act (ADA) and environmental regulations. While it does not report any current material violations, it acknowledges the potential for significant costs related to compliance or remediation.

Capital Structure and Securities

• Securities Registered: The company has multiple classes of “operating partnership units” including Series ES (NYSE Arca: BA) and Series 250 (NYSE Arca: FISK).
• Outstanding Units (as of February 24, 2026):
  • Series ES: 16,479,998 units
  • Series 60: 4,237,737 units
  • Series 250: 2,206,101 units

Regulatory and Governance Highlights

• SEC Filing Status: The company is a well-known seasoned issuer, a large accelerated filer, and is subject to all standard reporting requirements.
• Internal Controls: The registered public accounting firm has attested to the effectiveness of internal controls over financial reporting under Section 404(b) of the Sarbanes-Oxley Act.
• No Restatements or Shell Status: The report confirms there were no corrections of previously issued financial statements requiring restatements, and the company is not a shell company.

Potential Price-Sensitive Factors for Shareholders

• Rental Rate Reversion: The company highlights that many current leases are under market rates, indicating potential for significant rental income upside as leases are renewed at higher market rates.
• Balance Sheet Strength: Financial flexibility may allow the company to pursue acquisitions or withstand market downturns, impacting future growth and shareholder returns.
• Sustainability Leadership: Industry-leading sustainability initiatives may attract ESG-focused investors and tenants, potentially boosting asset values and share price.
• Segment Diversification: The Observatory segment provides non-traditional income, offering a hedge against pure office or retail market downturns.
• Legal and Environmental Compliance: While no current material issues are reported, ongoing compliance costs and potential future risks (e.g. environmental remediation) are flagged as areas for investor attention.

Conclusion

Empire State Realty OP, L.P. continues to focus on high-quality asset management, financial strength, and sustainability. Its positioning in the New York City market, diversified revenue streams, and forward-looking sustainability efforts provide a compelling value proposition for investors. The potential for rental rate increases as leases roll to market, combined with a strong balance sheet, may support future growth and share price appreciation.
