EMPIRE STATE REALTY TRUST ANNOUNCES THIRD QUARTER 2014 RESULTS

- Reports Core FFO of $0.25 Per Fully Diluted Share -

New York, New York, October 29, 2014 - Empire State Realty Trust, Inc. (NYSE: ESRT) (the “Company”), a real estate investment trust with office and retail properties in Manhattan and the greater New York metropolitan area, today reported operational and financial results for the third quarter 2014.

“We are very pleased with our performance in our first year as a public company. We have consistently stated and executed on the plans we set out prior to our IPO. In the third quarter we redeveloped and leased office and retail space to high quality tenants at very strong leasing spreads and continued towards the completion of our base building redevelopment at the Empire State Building. We added two quality assets with what we think is very good upside to our portfolio through the exercise of our options at 112 West 34th Street and 1400 Broadway, and meaningfully enhanced our balance sheet flexibility. Our third quarter leasing to high quality tenants at very strong positive spreads on new leases underscores the inherent opportunity in our ongoing redevelopment program. Looking ahead, Empire State Realty Trust is well positioned to continue delivering compelling built-in growth and drive value for all shareholders,” stated Anthony E. Malkin, Empire State Realty Trust’s Chairman, Chief Executive Officer, and President.
