NEW YORK, Jan. 06, 2026 (GLOBE NEWSWIRE) -- SL Green Realty Corp. (NYSE:SLG), Manhattan’s largest office landlord, and Rockpoint, a Boston-based real estate private equity firm, today announced a joint venture for the ownership of 100 Park Avenue through SL Green’s sale of a 49% interest to Rockpoint at a gross asset valuation of $425.0 million.

“We’re excited to begin our partnership with Rockpoint at 100 Park Avenue in a transaction that underscores the strength of high-quality office assets in premier locations in an improving Manhattan office market,” said Harrison Sitomer, Chief Investment Officer at SL Green.

“We have known the SL Green team for a long time and look forward to partnering to maintain and enhance 100 Park’s positioning as a highly desirable midtown office destination,” said Dan Domb, a Managing Member and Chief Operating Officer at Rockpoint. “Office has been a significant focus for Rockpoint throughout our 31-year history, we know the asset class extremely well and have always been disciplined about investing. As our first significant post-COVID office investment, 100 Park represents the kind of highly targeted opportunity that we find attractive today given the vibrancy of New York and the favorable supply/demand dynamics for high quality and extremely well-located properties like this one.”

Located steps away from Grand Central Terminal, 100 Park Avenue is a 36-story, 905,000-square-foot office tower in Midtown Manhattan. The building boasts a recently renovated amenity center on the second floor, offering a state-of-the-art lounge, golf simulator, game room, personal training studio, and conference rooms. Major tenants include Alphasights, which signed a 10-year lease for 192,630 square feet in March 2022, and Alvarez & Marsal Holdings, LLC, which signed a 15-year lease for 220,221 square feet in December 2024.

SL Green’s portfolio on Park Avenue includes the newly acquired Park Avenue Tower, One Vanderbilt Avenue, 500 Park Avenue, 450 Park Avenue, 280 Park Avenue, 245 Park Avenue and 125 Park Avenue.
