New York, New York, February 22, 2017 - 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 2016.

“We are pleased with our strong fourth quarter and full year 2016 results. We continue to consolidate, redevelop and re-lease space to larger, higher credit quality tenants at materially higher rents and create value. During 2016, we leased 992,000 square feet of office and retail space which resulted in market-leading spreads on both new Manhattan office and total portfolio leases of 50.6% and 32.7%, respectively. Current and prospective tenants continued to be attracted to our modernized spaces within well-located, amenity-rich office buildings,” stated John B. Kessler, Empire State Realty Trust’s President and Chief Operating Officer.

“Observatory revenues grew 11.2% year-over-year to record level driven by increased tourist visits, improved revenue mix and favorable weekend weather conditions. We also grew and added to the flexibility of our low-levered balance sheet during the year with a $622 million investment by an affiliate of the Qatar Investment Authority and the expansion of our line of credit to $1.1 billion. As we look forward in 2017, we remain committed to unlock the embedded growth within our portfolio and the added liquidity, strength, and flexibility in our balance sheet positions us to fund future growth opportunities and create long-term value for our shareholders,” added Kessler.
