New York, New York, October 31, 2018 - 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 third quarter of 2018.

“We continued to execute our long-term strategy to consolidate, redevelop and re-lease space to larger, higher credit quality tenants at higher rents and create long-term value for shareholders. During the quarter, we leased approximately 354,000 square feet of office and retail space that resulted in a spread of 27.3% on new Manhattan office and a 24.1% increase in mark-to-market rent portfolio-wide over previous fully escalated rents on new, renewal, and expansion leases. Our well-located, modernized office buildings continue to attract a diverse group of prospective tenants. Our value price point between trophy Class A and Class B properties positions us well to capture steady tenant demand,” stated John B. Kessler, Empire State Realty Trust’s President and Chief Operating Officer.

“Year-to-date, Observatory revenue increased 2.6% and Observatory net operating income increased 2.4%, as compared with the first nine months of 2017, driven primarily by improved pricing. We are pleased with the positive market response to our new Observatory entrance that opened in the third quarter and look forward to sharing more of the enhanced visitor experience as we complete our work by the end of 2019,” added Kessler. “We continue to manage our balance sheet to fund our redevelopment program and shareholder value enhancement opportunities.”

Significant Leases Executed During the Third Quarter 2018

Empire State Building

The Company continues to renovate and lease the 2.8 million rentable square foot Empire State Building, its flagship property.

During the third quarter 2018, the Company opened the new Observatory entrance, which is the first phase of a fully reimagined Observatory experience. The new entrance provides Observatory visitors with an enhanced visitor journey focused on key recallable moments that celebrate the authentic and iconic Empire State Building experience. The Company has improved the customer experience with new self-serve, digital ticketing kiosks and more efficient security screening. Furthermore, the new entrance reroutes approximately four million annual visitors from the Fifth Avenue entrance, which reduces congestion in the Fifth Avenue lobby and improves the value of the office and 34^th Street retail components of the Empire State Building.

5

During the third quarter 2018, the Company signed ten office leases at the Empire State Building, representing 61,886 rentable square feet in the aggregate.

Observatory revenue for the third quarter 2018 was $40.2 million, a 2.4% increase from $39.3 million in the third quarter 2017. The Observatory hosted approximately 1,168,000 visitors in the third quarter 2018 compared to 1,237,000 visitors in the third quarter 2017, a decrease of 5.6%. There were 11 bad weather days compared to 14 bad weather days in the third quarter 2017. For the third quarter 2018, the Company estimates that bad weather days resulted in approximately twenty four thousand less visitors than in the prior year period based upon the timing of the bad weather days.

Observatory revenue was $96.7 million for the nine months ended September 30, 2018, a 2.6% increase from $94.2 million for the nine months ended September 30, 2017. The 102nd floor observation deck was closed in the first quarter of 2018 for the scheduled replacement of original elevator machinery with a new, higher speed glass elevator. Adjusting for first quarter revenue from the 102^nd floor observation deck (which was $1.9 million in 2017), revenue would have increased 4.7% for the nine months ended September 30, 2018 as compared with the same period in 2017. For the nine months ended September 30, 2018, the Observatory hosted approximately 2,860,000 visitors, compared to 2,949,000 visitors for the same period in 2017, a decrease of 3.0%. For the nine months ended September 30, 2018, there were 37 bad weather days compared to 51 bad weather days in the nine months ended September 30, 2017.

Balance Sheet

At September 30, 2018, there was no outstanding balance under the Company’s $1.1 billion unsecured revolving credit facility and the Company’s $265 million term loan facility was fully drawn. The facilities have an accordion feature allowing for an additional increase in the maximum aggregate principal balance to $1.75 billion under certain circumstances. The Company held cash, cash equivalents and short-term investments of $629.7 million at September 30, 2018.
