NEW YORK, Jan. 15, 2026 (GLOBE NEWSWIRE) -- SL Green Realty Corp. (NYSE:SLG), Manhattan’s largest office landlord, today announced that it has closed on the previously announced acquisition of Park Avenue Tower, located at 65 East 55th Street, for $730.0 million.

The acquisition was financed with a new, five-year, fixed rate $480.0 million mortgage that was executed in the CMBS market by Wells Fargo, with participation from JP Morgan and Bank of America. The mortgage carries a stated coupon of 5.30%, which SL Green has hedged to an effective rate of 5.25%.

“Closing on Park Avenue Tower with best-in-class financing fortifies our substantial presence on Park Avenue, the strongest office submarket in the country," said Harrison Sitomer, Chief Investment Officer at SL Green . "With this acquisition, the new financing, and the recent sale of a joint venture interest in 100 Park Avenue, we are well under way on the execution of our 2026 capital markets strategy.”

Located block-through between 55th and 56th Streets, Park Avenue Tower is a 36-story, 621,824 square foot, Class A office building designed by internationally acclaimed architect Helmut Jahn. Completed in 1986, it is one of the most modern assets in the submarket, with upgraded infrastructure and newly renovated interiors that, together with its distinctive architectural design, solidify its reputation as one of the most desirable addresses on Park Avenue.

Recent enhancements to Park Avenue Tower include a reimagined plaza by MdeAS Architects, high-end prebuilt office suites by Gensler, a world class lobby and well-appointed amenities by Gonzalez Architects. These upgrades elevate the building’s arrival experience and deliver a flexible, modern tenant environment, positioning the property as a top choice for leading financial institutions and hedge funds.
