ITEM 2. UNREGISTERED SALES OF EQUITY S ECURITIES, USE OF PROCEEDS, AND ISSUER PURCHASES OF EQUITY SECURITIES Aimco Aimco’s Common Stock is listed and traded on the NYSE under the symbol “AIV”. On August 5, 2026, there were 145,236,898 shares of Common Stock outstanding, held by 840 stockholders of record. The number of holders does not include individuals or entities who beneficially own shares but whose shares are held of record by a broker or clearing agency but does include each such broker or clearing agency as one record holder. Unregistered Sales of Equity Securities From time to time, Aimco may issue shares of its Common Stock in exchange for OP Units, defined under the Aimco Operating Partnership heading below. Such shares are issued based on an exchange ratio of one share for each OP Unit. Aimco may also issue shares of its Common Stock in exchange for limited partnership interests in consolidated real estate partnerships. During the three months ended June 30, 2026, 1,524,343 shares of Common Stock were issued in exchange for OP Units. Such shares were issued in reliance on Section 4(a)(2) of the Securities Act of 1933, as amended. In addition to any issuances pursuant to transactions of the types discussed above, there were no unregistered sales of equity securities made by Aimco during the three months ended June 30, 2026. 39 Table of Contents Repurchases of Equity Securities On July 28, 2022, Aimco announced that its Board authorized Aimco to repurchase up to 15 million shares of its outstanding Common Stock. On November 6, 2023, Aimco announced that the Board authorized Aimco to repurchase up to an additional 15 million shares of its outstanding Common Stock, for a total of 30 million shares. As of June 30, 2026, Aimco was authorized to repurchase up to 16.2 million shares of its outstanding Common Stock. Subject to certain blackout restrictions, these repurchases may be made from time to time in the open market or in privately negotiated transactions. These share repurchase authorizations have no expiration date. Since Aimco's Board of Directors announced the expansion of its strategic review process on January 9, 2025, no shares of common stock have been repurchased by Aimco. Aimco Operating Partnership There is no public market for OP Units, and Aimco Operating Partnership has no intention of listing OP Units on any securities exchange. In addition, Aimco Operating Partnership’s Partnership Agreement restricts the transferability of OP Units. On August 5, 2026, there were 151,530,553 OP Units and equivalents outstanding (of which 145,236,898 were held by Aimco), that were held by 1,774 unitholders of record. Unregistered Sales of Equity Securities Aimco Operating Partnership did not issue any unregistered OP Units during the three months ended June 30, 2026. Repurchases of Equity Securities Aimco Operating Partnership’s Partnership Agreement generally provides that after holding OP Units for one year, limited partners other than Aimco have the right to redeem their OP Units for cash or, at Aimco’s election, shares of Aimco Common Stock on a one-for-one basis (subject to customary antidilution adjustments). During the three months ended June 30, 2026, 1,524,343 OP Units were redeemed in exchange for shares of Common Stock on a one-for-one basis and 2,196 OP Units were redeemed in exchange for cash at an aggregate weighted average price per unit of $4.15. The following table summarizes repurchases, or redemptions in exchange for cash, of the Aimco Operating Partnership’s equity securities held by third parties for the three months ended June 30, 2026: Fiscal Period Total Number of Units Repurchased Weighted Average Price Paid per Unit Total Number of Units Purchased as Part of Publicly Announced Plans or Programs Maximum Number of Units That May Yet Be Purchased Under Plans or Programs (1) April 1 - 30, 2026 — $ — NA NA May 1 - 31, 2026 — — NA NA June 1 - 30, 2026 2,196 4.15 NA NA Total 2,196 $ 4.15 (1) The terms of the Aimco Operating Partnership’s Partnership Agreement do not provide for a maximum number of units that may be repurchased, and other than the express terms of its Partnership Agreement, the Aimco Operating Partnership has no publicly announced plans or programs of repurchase. However, for Aimco to repurchase shares of its Common Stock, the Aimco Operating Partnership must make a concurrent repurchase of its OP Units held by Aimco at a price per unit that is equal to the price per share Aimco pays for its Common Stock. Dividend and Distribution Payments As a REIT, Aimco is required to distribute annually to holders of its Common Stock at least 90.0% of its “real estate investment trust taxable income,” which, as defined by the Code and United States Department of Treasury regulations, is generally equivalent to net taxable ordinary income. Aimco’s Board determines and declares Aimco’s dividends. In making a dividend determination, Aimco’s Board considers a variety of factors, including REIT distribution requirements, current market conditions, liquidity needs, and other uses of cash, such as deleveraging. In connection with the Plan of Sale and Liquidation, United States stockholders may receive one or more liquidating distributions. The amount of any liquidating distribution will be applied first to reduce a United States stockholder’s adjusted tax basis in its Common Stock, but not below zero. A United States stockholder’s adjusted tax basis in its Common Stock will generally be equal to the stockholder’s cost of its shares, reduced by any prior distributions that were treated as reductions in basis rather than taxable dividends. To the extent that distributions pursuant to the Plan of Sale and Liquidation exceed a United States stockholder’s basis in its Common Stock, the excess will constitute taxable gain and be recognized in the year in which the distribution is received. If the total amount of liquidating distributions received by a United States stockholder is less than the 40 Table of Contents adjusted tax basis of its shares, the United States stockholder will generally recognize a loss in the year in which the final liquidating distribution is received. However, a future abandonment of the Plan of Sale and Liquidation subsequent to the payment of liquidating distributions could complicate the tax consequences to our stockholders, as described in greater detail in our definitive proxy statement, filed with the SEC on January 2, 2026. The Board of Aimco Operating Partnership’s general partner determines and declares distributions on OP Units. Aimco, through a wholly-owned subsidiary, is the sole general partner of Aimco Operating Partnership. As of June 30, 2026, Aimco owned 95.1% of the legal interest in the OP Units of Aimco Operating Partnership and 95.8% of the dilutive economic interest of Aimco Operating Partnership. Aimco Operating Partnership holds all of our assets and manages the daily operations of our business. The distributions paid by Aimco Operating Partnership to Aimco are used to fund the dividends paid to Aimco's stockholders. Accordingly, the per share dividends Aimco pays to its stockholders generally equal the per unit distributions paid by Aimco Operating Partnership to holders of its OP Units. 41 Table of Contents ITEM 6.
