- Reports Core FFO of $0.22 Per Fully Diluted Share -

New York, New York, July 30, 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 second quarter 2014.

“We are pleased with our second quarter leasing and Empire State Building Observatory performance. Leasing volume, quality of tenants, and rental spreads all met or exceeded our expectations. The Observatory had record attendance in June, and in the year to date we outpaced the financial performance of the comparable period in 2013. During the quarter we exercised our option to purchase the ground leaseholds at 112 West 34th Street and 1400 Broadway on which we subsequently closed on July 15, 2014. We believe the exercise of our options unlocks a source of additional potential future growth for the Company. After the transaction, we have maintained a strong, flexible balance sheet with strong credit metrics and meaningful capacity to support future growth. Our team continues to execute on behalf of shareholders at a very high level,” stated Anthony E. Malkin, Empire State Realty Trust’s Chairman, Chief Executive Officer, and President.
