New York, New York, April 29, 2025 – Empire State Realty Trust, Inc. (NYSE: ESRT) is a NYC-focused REIT that owns and operates a portfolio of well-leased, top of tier, modernized, amenitized, and well-located office, retail, and multifamily assets. ESRT’s flagship Empire State Building, the “World's Most Famous Building,” features its iconic Observatory that was declared the #1 Attraction in the World – and the #1 Attraction in the U.S. for the third consecutive year– in Tripadvisor’s 2024 Travelers’ Choice Awards: Best of the Best Things to Do. The Company is a recognized leader in energy efficiency and indoor environmental quality. Today the Company reported its operational and financial results for the first quarter 2025. All per share amounts are on a fully diluted basis, where applicable.

First Quarter and Recent Highlights

Net Income of $0.05 per share.

Core Funds From Operations (“Core FFO”) of $0.19 per share, compared to $0.21 per share in the first quarter 2024.

Same-Store Property Cash Net Operating Income (“NOI”), which excludes lease termination fees, decreased 1.9% year-over-year. The first quarter change was primarily attributed to increases in operating expenses and real estate taxes and a decrease from the $1.5 million non-recurring revenue items recognized in the first quarter of 2024. These reductions in NOI were partially offset by higher cash rental revenue and tenant reimbursement income. Adjusted for non-recurring items, first quarter Same-Store Property Cash NOI increased +0.4%.

Signed approximately 229 thousand rentable square feet of office leases. In our Manhattan office portfolio, blended leasing spreads were +10.4%, the 15^th consecutive quarter of positive leasing spreads.

The Manhattan office portfolio is 93.0% leased and the total commercial portfolio is 92.5% leased as of March 31, 2025. The Manhattan office portfolio is 88.1% occupied and the total commercial portfolio is 87.9% occupied as of March 31, 2025. The Company’s leased percentage and occupancy guidance for the year remains unchanged. Consistent with the Company’s comments in its last earnings call, net absorption contracted sequentially in the first quarter and the Company expects occupancy and leased percentage to increase by year-end.

Empire State Building Observatory generated NOI of $15.0 million.

As of March 31, 2025, the Company’s property portfolio contained 7.9 million rentable square feet of office space, 0.8 million rentable square feet of retail space and 732 residential units, which were occupied and leased as shown below.
