APARTMENT INVESTMENT & MANAGEMENT CO

Redeemable noncontrolling interests consist of equity interests held by a limited partner in a consolidated real estate partnership that generally, after a specified holding period, has the right to require such partnership to redeem all or a portion of the noncontrolling interest in accordance with the partnership agreement. If a consolidated real estate partnership includes redemption rights that are not within our control, the noncontrolling interest is included as temporary equity.

Redeemable noncontrolling interests in consolidated real estate partnerships as of December 31, 2025, consists of the following:(i) a preferred equity interest that receives 8.0% preferred return per annum in an entity that owns a portfolio of operating apartment communities,(ii)a preferred equity interest accruing 9.7% preferred return per annum in a consolidated joint venture with a residential apartment community in lease-up, and (iii) a preferred equity interest accruing 14.5% preferred return per annum in an entity that owns a waterfront ground-up development. Capital contributions, distributions, and net income attributable to redeemable noncontrolling interests in consolidated real estate partnerships are determined in accordance with the relevant partnership agreements. These interests are presented as Redeemable noncontrolling interests in consolidated real estate partnerships in our Consolidated Balance Sheets as of December 31, 2025.

The assets of our consolidated real estate partnerships must first be used to settle the liabilities of the consolidated real estate partnerships. The consolidated real estate partnership’s creditors do not have recourse to the general credit of Aimco Operating Partnership.

The following table shows changes in our redeemable noncontrolling interests in consolidated real estate partnerships during the years ended December 31, 2025 , 2024, and 2023 (in thousands):

(1)In May 2025, we purchased all of the outstanding redeemable noncontrolling interest from our development partner in the Strathmore Square property for a cash purchase price of $5.0 million.

(2) In September 2024, we secured a $55.5 million preferred equity commitment from a third-party for the development of a luxury water-front rental development in Miami, Florida. Costs incurred were treated as a discount to Redeemable noncontrolling interests in consolidated real estate partnerships and are amortized using the effective interest method in accordance with GAAP.

Mezzanine Investment

In November 2019, Aimco Predecessor made afive-year, $275.0 million mezzanine loan to the partnership owning the “Parkmerced Apartments” located in southwest San Francisco (the “Mezzanine Investment”). The loan bears interest at a 10% annual rate, accruing if not paid from property operations. While legal ownership of the subsidiaries that originated and hold the Mezzanine Investment was retained by AIR following the Separation, AIR is obligated to pass payments received on the Mezzanine Investment to us, and we are obligated to indemnify AIR against any costs and expenses related thereto. We have the risks and rewards of ownership of the Mezzanine Investment.

Throughout the term of the Mezzanine Investment, we have performed an assessment to determine whether the fair value of the Mezzanine Investment is less than its net carrying value on an other-than-temporary basis. In 2023, we determined our Mezzanine Investment was incrementally impaired after considering various factors, including the mezzanine loan’s nearing maturity date and further decline in value of the real estate collateral. As a result, we recognized a non-cash impairment charge of $158.0 million to reduce the carrying value of the Mezzanine Investment tozero.

In June 2023, we closed on the sale of a 20% non-controlling participation in the Mezzanine Investment for $33.5 million. The partial sale and transfer of the financial interest did not qualify for sale accounting and therefore, we recorded the cash received from the purchaser as a liability, which is included in Accrued liabilities and other in our Consolidated Balance Sheets. Although the cash received is accounted for as a liability, no amount is due to the purchaser until after we receive $134.0 million plus an annualized return. While the Mezzanine Investment had not been repaid and was in maturity default as of December 31, 2025, we are precluded from derecognizing the liability until it has been extinguished in accordance with GAAP.

In connection with the participation sold, the purchaser also made a $4.0 million non-refundable payment for the option to acquire the remaining 80% in the Mezzanine Investment. The option expired unexercised in the quarter ended December 31, 2023. As a result, we recognized the non-refundable payment in Mezzanine investment income (loss), net in our Consolidated Statements of Operations.
