EMPIRE STATE REALTY TRUST ANNOUNCES FOURTH QUARTER 2015 RESULTS

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

New York, New York, February 22, 2016 - 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 its operational and financial results for the fourth quarter of 2015.

“We are pleased with our strong fourth quarter and full year 2015 results, including a 9% increase in full year Core FFO per share, which reflect the successful execution of our strategy to consolidate, redevelop and re-lease space to larger, higher credit quality tenants. During 2015, we leased approximately 1.2 million square feet of office and retail space, which represents 54% growth from the prior year. Most importantly, our leasing team achieved rent spreads in excess of 73.5% on the total portfolio and over 43% on new leases signed in our Manhattan office portfolio. Additionally, we overcame challenging New York City tourist trends and the opening of One World Trade Center’s observatory and produced full year revenue from our Observatory that was slightly in excess of the prior year,” stated John B. Kessler, Empire State Realty Trust’s President and Chief Operating Officer.

Mr. Kessler continued, “Finally, our well-capitalized, low-levered balance sheet, with limited near term debt maturities, enables us to support our future growth plans. In the coming years, we will continue to unlock the embedded, de-risked growth within our portfolio and create long term value for our shareholders, with whom our management team remains highly aligned. We had limited new net borrowings during the year and continue to maintain high levels of liquidity.”
