SL GREEN REALTY Business Summary

SL Green Realty Corp. (NYSE: SLG) is a fully integrated real estate investment trust (REIT) and stands as Manhattan's largest office landlord, primarily focused on the acquisition, management, and value maximization of commercial properties in New York City. The company generates approximately 90% of its revenue through property rental income and escalations from a high-quality portfolio concentrated in Midtown Manhattan. Its secondary revenue streams include management and leasing fees, interest income from its debt and preferred equity investment platform, and ticket sales from SUMMIT One Vanderbilt, its flagship observation deck. SL Green operates through three primary business segments: Real Estate, Debt and Preferred Equity Investments, and SUMMIT. Within the competitive landscape, the firm contends with major REITs such as Vornado Realty Trust, BXP (formerly Boston Properties), and Empire State Realty Trust. SL Green distinguishes itself as the dominant market leader in the New York City office sector, maintaining a specialized, high-density focus on the Manhattan submarket compared to the more geographically diversified portfolios of its peers. Founded in 1980 by Stephen L. Green, who now serves as Chairman-Emeritus, the company is led by Chairman and CEO Marc Holliday, who also currently serves as Interim President. Holliday, who joined the firm in 1998 and holds a Master’s in Real Estate Development from Columbia University, has overseen the company’s growth into a dominant urban landlord. The executive leadership team includes Matthew DiLiberto as Chief Financial Officer, Harrison Sitomer as Chief Investment Officer, and Andrew Levine as Chief Legal Officer.

Alschuler Jr. and includes notable industry figures such as Peggy Lamb and Lauren Dillard, providing deep expertise in urban planning and global capital markets.
