Item 1.01Entry into a Material Definitive Agreement.

As previously reported, on August 15, 2025, 250 Seaport District, LLC (the “Seller”), a subsidiary of Seaport Entertainment Group Inc. (the “Company”), entered into a Purchase and Sale Agreement (the “Agreement”) with 250 Water Street Owner LLC (the “Buyer”) for the sale of a mixed-use development project located at 250 Water Street (“250 Water Street”). The Buyer is an affiliate of Tavros Holdings LLC, a privately owned real estate investment management and development firm based in New York City. The Buyer does not have any material relationship with the Company or its affiliates, other than in respect of the Agreement.

On December 15, 2025, the Seller and the Buyer entered into a First Amendment to the Agreement (the “Amendment”) to provide that, among other things and notwithstanding anything to the contrary contained in the Agreement, the date of the closing of the transactions contemplated under the Agreement (the “Closing Date”) will be January 28, 2026, and the Buyer will have no further right to extend or adjourn the Closing Date. The Buyer will have the right to request acceleration of the closing prior to such extended Closing Date; provided that the Seller will not be obligated to close prior to January 28, 2026.

As a result of the Buyer previously electing to exercise certain provisions in the Agreement to extend the date of the closing of the transactions contemplated under the Agreement, the sale price for 250 Water Street has been increased to a total of $152.0 million.  

Notwithstanding the foregoing, the sale of 250 Water Street is subject to certain closing conditions, which are not currently satisfied. Accordingly, there can be no assurances that the sale of 250 Water Street will be completed on the terms or timing described in this Current Report on Form 8-K, or at all.

The foregoing description of the Amendment is not complete and is qualified in its entirety by reference to the full text of the Amendment, which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated herein by reference.
