Description of Business and Organization | Description of Business and Organization As used in these consolidated financial statements, unless the context otherwise requires, “we,” “us,” “our,” and the “Company,” mean Empire State Realty OP, L.P. and its consolidated subsidiaries. Empire State Realty OP, L.P. (the "Operating Partnership") is the entity through which Empire State Realty Trust, Inc. (NYSE: ESRT) conducts all of its business and owns (either directly or through subsidiaries) substantially all of its assets. ESRT is a NYC-focused real estate investment trust ("REIT") that owns and operates a portfolio of well-leased, top of tier, modernized, amenitized, and well-located office, retail, and multifamily assets.

The Company is a recognized leader in energy efficiency and indoor environmental quality. As of June 30, 2026, our portfolio was comprised of approximately 7.5 million rentable square feet of office space, 0.8 million rentable square feet of retail space and 743 residential units, which are located in New York City. Our office portfolio included 9 properties (including one long-term ground leasehold interest), all of which are located in Manhattan. Additionally, we have entitled land in Stamford, Connecticut that can support the development of either office or residential per local zoning. We were organized as a Delaware limited partnership on November 28, 2011 and commenced operations upon completion of the initial public offering of ESRT’s Class A common stock and related formation transactions on October 7, 2013 (the "Offering"). ESRT's Class A common stock, par value $0.01 per share, is listed on the New York Stock Exchange under the symbol "ESRT."
