SL Green Realty Corp. and SL Green Operating Partnership, L.P. have jointly filed their annual report on Form 10-K for the fiscal year ended December 31, 2025. The company, a self-managed real estate investment trust (REIT), primarily focuses on commercial properties, especially office spaces, in the New York metropolitan area, particularly Manhattan. As of June 30, 2025, the aggregate market value of the common stock held by non-affiliates was approximately $3.9 billion. As of February 13, 2026, there were 71,031,183 shares of SL Green Realty Corp.'s common stock outstanding.
The company's financial performance for 2025 showed a significant increase in rental revenue, reaching $680.1 million compared to $606.0 million in 2024, representing a 12.2% increase. This growth was primarily attributed to recent property consolidations and acquisitions. However, SUMMIT Operator revenue decreased to $122.3 million from $133.2 million in the previous year, reflecting a decline of 8.2%. The company's net loss was $(96.9) million, a significant decrease compared to the net income of $30.2 million in 2024. This shift was influenced by increased interest expenses, higher depreciation and amortization, and losses from unconsolidated joint ventures.
Strategic developments during the year included the acquisition of 346 Madison Avenue and 500 Park Avenue, as well as increasing its interest in 100 Park Avenue and 800 Third Avenue. Conversely, the company strategically disposed of a 5.0% interest in One Vanderbilt Avenue and a 49.0% joint venture interest in 100 Park Avenue. These transactions aimed to optimize the portfolio and generate capital for reinvestment. The company also announced plans to expand the SUMMIT experience to Paris, France, expected to open in 2027, and is evaluating other international and domestic locations.
Key operational developments included signing 199 Manhattan office leases covering 2,568,551 square feet and increasing same-store Manhattan office occupancy to 93.0%. The company's debt and preferred equity investments had a book value of $168.4 million as of December 31, 2025. The company employed 1,289 employees as of December 31, 2025. The company's near-term absolute Scope 1 and Scope 2 emissions reduction targets have been approved by the SBTi; however, the company is shifting away from using the SBTi-validated targets to focus on a more locally tailored decarbonization strategy. In 2026, the Company will measure performance towards a Net-Zero Operations goal (Scope 1 & 2) by 2050, which is aligned with Urban Land Institute’s (ULI) Greenprint Framework.
Looking ahead, SL Green aims to maximize stockholder returns through strategic leasing, property management, acquisitions, development, and debt investments. The company intends to maintain a liquid balance sheet and access diversified capital sources. However, the report also acknowledges potential risks, including declines in demand for office space, competition for tenants, and the impact of economic and geopolitical conditions. The company also faces risks associated with climate change and compliance with environmental regulations, particularly in New York City.
