Item 2.06. Material Impairments Consistent with the strategic asset sales plan outlined at BXP, Inc.’s September 2025 Investor Day, on May 27, 2026, a subsidiary of Boston Properties Limited Partnership (“BPLP”) entered into an agreement to sell certain property (the "Property") comprised of (1) the leasehold interest in the real property commonly known as Sumner Square, located at the corner of 17th and M Street, NW in Washington, DC, and (2) the improvements located thereon, consisting of three buildings ((a) 1615 M Street, NW, Washington, DC, (b) the Magruder Building, 1625 M Street, NW, Washington, DC and (c) the Sumner Annex, 1215 17th Street, NW, Washington, DC), for a gross purchase price of $63 million. BPLP is the entity through which BXP, Inc. (the “Company”) conducts substantially all of its business and owns, either directly or through subsidiaries, substantially all of its assets. BXP is the sole general partner of BPLP. Under the agreement, the buyer paid a non-refundable cash deposit of approximately $6 million that will be credited against the purchase price at closing. Because the carrying value of the Property exceeds the expected net proceeds from the contemplated sale, the Company and BPLP will recognize a non-cash impairment loss of approximately $18 million and $17 million, respectively, in the second quarter of 2026 in accordance with GAAP. The Company expects this impairment loss to reduce net income attributable to BXP, Inc. and net income attributable to BPLP per diluted share/unit for the second quarter and full year of 2026 by approximately $0.10 per diluted share/unit, but it will have no impact on Funds from Operations. There can be no assurance that the sale will be consummated on the terms currently contemplated or at all. Item 9.01. Financial Statements and Exhibits. (d) Exhibits.
