Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

On October 1, 2026, Jennifer Johnson, the Executive Vice President and Chief Administrative Officer of Apartment Investment and Management Company (“Aimco” or the “Company”), notified the Company of her intent to resign, effective as of November 1, 2026 (the “Resignation Date”), from all positions held with the Company and its subsidiaries for “Good Reason” under the terms of the Company’s Executive Severance Policy, dated October 22, 2018, as amended (the “Executive Severance Policy”). The Company has accepted Ms. Johnson’s resignation for Good Reason based on the diminution in her responsibilities and duties in connection with the Plan of Sale and Liquidation approved by the Company's shareholders on February 6, 2026 (the “Plan of Sale and Liquidation”).

Ms. Johnson’s resignation on the Resignation Date will constitute a severance-qualifying resignation for Good Reason following a “Change in Control” (or similar term) under the Executive Severance Policy and the Company’s other compensation and benefit plans, which “Change in Control” (or similar term) is also occurring in connection with the sale or disposition of the Company’s assets pursuant to the Plan of Sale and Liquidation. She will therefore be eligible to receive the payments and benefits to which she is entitled under the Executive Severance Policy, the cash award letter agreement by and between Ms. Johnson and the Company, dated April 16, 2026, and the applicable equity award agreements to which she is party, in each case, subject to the terms and conditions thereof, including the execution and non-revocation of a standard release of claims in favor of the Company.

To ensure an orderly transition of her responsibilities, Ms. Johnson has agreed to remain available to Aimco as a consultant on an as-needed basis following the Resignation Date. Pursuant to the separation agreement entered into in connection with her resignation on October 1, 2026 (the “Separation Agreement”), Ms. Johnson will provide limited transitional services to Aimco until May 2, 2027, assisting with the transfer of her duties and providing strategic transitional advice on pending matters for up to ten (10) hours per month at an hourly rate of $750, plus reasonable expenses (the “Consulting Arrangement”). The Consulting Arrangement is terminable by either Ms. Johnson or Aimco for any reason or no reason upon thirty (30) days’ written notice.

The foregoing summary does not purport to be complete and is qualified in its entirety by reference to the full text of the Separation Agreement, a copy of which is attached hereto as Exhibit 10.1 and incorporated herein by reference.
