SL Green Announces Acquisition of 346 Madison Avenue

Premier Midtown Development Site

NEW YORK, Sept. 02, 2025 (GLOBE NEWSWIRE) — SL Green Realty Corp. (NYSE:SLG), Manhattan’s largest office landlord, today announced that it has entered into a contract to purchase 346 Madison Avenue and the adjacent site at 11 East 44th Street, for $160.0 million. The transaction is expected to close during the fourth quarter of 2025, subject to customary closing conditions.

“These assets are in an exceptional location just steps from One Vanderbilt. As we continue to prioritize well-located opportunities in our core sub-markets, these properties provide us the opportunity to pursue a world-class, ground-up new office development in the heart of the strongest office market in the country. We look forward to capitalizing on this unique investment to unlock its long-term value,” said Harrison Sitomer, Chief Investment Officer at SL Green.

The acquisition of the two adjoining buildings represents a strategic opportunity to create a best-in-class new building on a prominent development site in the heart of Midtown East. Combined, these properties can accommodate approximately 800,000 rentable square feet, pursuant to East Midtown rezoning. Tenant demand for new construction featuring forward thinking amenitization, column free floors, healthy workplace infrastructure and transit convenience remains robust and this site represents one of the finest opportunities to meet that demand.

Drew Isaacson and David Giancola of JLL advised on the transaction.
