01 Other Events

Item 8.01 Other Events. As previously reported, on August 5, 2025, certain subsidiaries of Apartment Investment and Management Company ("Aimco") and Aimco OP L.P. (collectively, the "Company" or "Seller") entered into one Agreement of Purchase and Sale (the "Agreement") with HGI Acquisitions, LLC (the "Purchaser"). The Purchaser is not affiliated with the Seller. Under the terms of the Agreement, the Seller agreed to sell to the Purchaser, five properties located in suburban Boston (Massachusetts, New Hampshire, and Rhode Island) (the "Boston Portfolio") for an aggregate purchase price of $740 million. On September 9, 2025, the Company completed the sale of four of the five properties located in suburban Boston to the Purchaser for an aggregate purchase price of $490 million with the fifth property closing at a later date to accommodate the assumption of the property loan pursuant to the terms of the Agreement. On September 15, 2025, the Company filed a Current Report on Form 8-K (the "Original Form 8-K"), which included the unaudited pro forma financial information of these four properties. On October 3, 2025, the Company completed the sale of the fifth property, Royal Crest Estates (Nashua), located in suburban Boston to the Purchaser for a gross purchase price of $250 million. In connection with the final phase of the Boston Portfolio sale, $173.4 million of non-recourse property debt was assumed by the Purchaser. The Company plans to use the incremental net proceeds from the sale, paid in cash, to reduce leverage and for general corporate purposes. While the disposition of Royal Crest Estates (Nashua) is individually insignificant, the Company is filing this amendment on Form 8-K/A to amend the Original Form 8-K to voluntarily add the unaudited pro forma financial information of the fifth property.
