EMPIRE STATE REALTY TRUST ANNOUNCES FIRST QUARTER 2016 RESULTS

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

- Leased 255,723 Square Feet of Office and Retail Space -

- Achieved a 50.9% Increase in Mark-To-Market Rent on New Manhattan Office Leases -

New York, New York, April 27, 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 first quarter of 2016.

“Our strong first quarter results, including a 10% increase in Core FFO per share over the prior year, reflect the successful execution of our strategy to consolidate, redevelop and re-lease space to larger, higher credit quality tenants at materially higher rents,” stated John B. Kessler, Empire State Realty Trust’s President and Chief Operating Officer. “In the face of solid leasing demand, our newly renovated space, coupled with our relatively low in-place expiring rents, achieved market-leading spreads on new Manhattan office and retail leases, which exceeded 50% and 110%, respectively, this quarter. Prospective tenants are attracted to our value price point at our well located, amenity-rich office buildings.”

“Observatory revenues increased 16.5% over the first quarter of last year, which can be attributed in parts to increased tourist visits, favorable weather conditions, the calendar shift of Easter weekend to the first quarter of 2016, and our revenue mix. Finally, our low-levered balance sheet remains strong and supports our strategy 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 past year and continue to maintain high levels of liquidity.”

The Observatory hosted approximately 719,000 visitors in the first quarter 2016 compared to 622,000 visitors in the first quarter 2015, an increase of 15.6%. A portion of this increase can be apportioned to the shift of the Easter weekend to the first quarter in 2016 from the second quarter in 2015. In the first quarter 2016, there were two bad weather days which fell on a weekend. This compares to the first quarter 2015, in which there were nine bad weather days which fell on weekends.

Balance Sheet

At March 31, 2016, there was no outstanding balance on the Company’s $800.0 million unsecured revolving credit facility.

At March 31, 2016, the Company had total debt outstanding of approximately $1.6 billion, with a weighted average interest rate of 4.14% per annum, and a weighted average term to maturity of 5.4 years.

During the quarter, the Company refinanced at a lower rate its 6.0% $20 million mortgage loan on its 10 Union Square East property. The new $50 million mortgage loan has a ten year term and bears interest at a fixed rate of 3.7%. The additional proceeds were used to reduce amounts outstanding under the Company’s unsecured revolving credit facility. The Company expensed $0.2 million of unamortized deferred finance costs and incurred a $0.4 million prepayment penalty, which will be offset by interest cost savings.
