Exhibit 99.1

SERIES ES, 60 AND 250 OPERATING PARTNERSHIP UNITS TO TRADE ON NYSE ARCA

ESRT CLASS A COMMON STOCK UNAFFECTED

New York, New York, October 10, 2013 — Empire State Realty Trust, Inc. (NYSE:ESRT) (the “Company”), a leading real estate investment trust with office and retail properties in Manhattan and the greater New York metropolitan area, today announced that it has commenced the process to transfer Series ES (NYSE:ESBA), 60 (NYSE:OGCP) and 250 (NYSE:FISK) listed operating partnership units to the NYSE Arca, Inc. (“Arca”). The operating partnership units are expected to begin trading on Arca on October 11, 2013; their ticker symbols are unchanged.

The operating partnership units are entitled to the same distributions on a per unit basis as ESRT Class A shares. However, they are non-voting securities with significantly less trading volume than ESRT Class A shares. An operating partnership unit is exchangeable for cash or shares of Class A common stock, on a one-to-one basis, at the Company’s election generally commencing on October 1, 2014.

ESRT has 82,225,000 shares of Class A common stock listed on the NYSE under the ticker ESRT. This announcement does not impact these Class A shares. The trading characteristics of the listed operating partnership units since they began trading led the NYSE and the Company to determine they were better suited to be listed on Arca.
