December 26, 2025

Dear Wesley,

As you know, in November 2025, the Board of Directors of Apartment Investment and Management Company (the “Company”) approved a plan of sale and liquidation (the “Plan of Sale and Liquidation”), conditioned on stockholder approval. It is expected that the Company will experience a change in control as a result of the asset sales that will occur as part of the Plan of Sale and Liquidation. Because your leadership is very important to the successful execution of our strategic plans, and in order to help mitigate the adverse impact on you of Sections 280G and 4999 of the Internal Revenue Code of 1986, as amended, in connection with a change in control, the Company is offering you (i) accelerated payment of your estimated 2025 annual cash bonus in the amount of $1,470,000 (the “Bonus Prepayment”) and (ii) a retention award in the amount of $5,250,000 (the “Retention Award”) in lieu of potential change in control severance benefits, to ensure that the Company will have the benefit of your continued employment and your strong commitment to the Company. As described further below, in light of the Retention Award, the Employment Agreement entered into by and between Aimco Development Company, LLC and you on October 27, 2021 (the “Employment Agreement”) is amended by this letter agreement (this “Agreement”) to remove certain provisions providing for enhanced change in control cash severance. Capitalized terms used and not otherwise defined in this Agreement shall carry the definitions ascribed to them in the Employment Agreement.

In order to receive the Bonus Prepayment and Retention Award, you must agree to the potential repayment provisions set forth in this Agreement, which could apply in certain limited circumstances. In addition, the Bonus Prepayment and the Retention Award remain subject to any applicable compensation clawback or recoupment policy of the Company.

Effective as of the date hereof, the Employment Agreement is hereby amended so that:

(i) Sections E(2)(a) and E(3)(a) are removed in their entirety and (ii) the definition of “Separation Amount” in Exhibit A to the Employment Agreement is removed and replaced in its entirely with the following definition:

The “Separation Amount” is estimated to be $[AMOUNT], equal to your estimated COBRA Severance Payment and your Pro-Rata Bonus, less applicable tax withholdings.

Provided that your employment with the Company has not previously been terminated due to your voluntary resignation, or termination by the Company for Cause, through the date on which the Bonus Prepayment is paid (the “Payment Date”), which will be no later than December 31, 2025, on the Payment Date the Company will pay you the Bonus Prepayment in the form of a lump sum cash payment, less applicable deductions and withholdings. In 2026, at the time the Company typically determines bonuses, it will determine the actual amount of your annual cash bonus for 2025 and will pay you any excess of such actual amount over your Bonus Prepayment (after taking into consideration individual performance factors, risk and/or compliance adjustments), less applicable deductions and withholdings.

Provided that your employment with the Company has not previously been terminated due to your voluntary resignation or termination by the Company for Cause, and subject to your subsequent compliance with the Release Requirement, on the Payment Date, the Company will pay you the Retention Award in the form of a lump sum cash payment, less applicable deductions and withholdings.

You agree that, if your employment terminates on or after the Payment Date under circumstances that would not otherwise result in the application of the repayment obligation pursuant to Section 5, then, in order to retain the Retention Award, within 45 days following your termination of employment, you will sign and return the release agreement attached hereto as Exhibit A. You acknowledge and agree that the Retention Award is conditioned on you timely signing and returning such release agreement and it becoming effective and irrevocable in accordance with its terms (the “Release Requirement”).

If you resign from employment with the Company for any reason, or the Company terminates your employment for Cause, in each case, on or before the date in 2026 upon which your 2025 annual bonus would otherwise be paid to you by the Company in the ordinary course of business, you agree to promptly (but in any event no later than 30 days following the date of your termination of employment) repay to the Company the after-tax amount of the Bonus Prepayment. If the Company terminates your employment without Cause prior to such date, you will have no obligation to repay to the Company any portion of the Bonus Prepayment.

If (i) you resign from employment with the Company for any reason prior to a Change in Control or (ii) the Company terminates your employment for Cause, in each case, prior to either (1) if the Plan of Sale and Liquidation is approved by the Company’s stockholders, the date of the final distribution to the Company’s stockholders pursuant to the Plan of Sale and Liquidation or (2) if the Plan of Sale and Liquidation is not approved by the Company’s stockholders, December 31, 2027, you agree to promptly (but in any event no later than 30 days following the date of your termination of employment) repay to the Company the after-tax amount of the Retention Award. If you resign from the Company following a Change in Control or the Company terminates your employment without Cause, in each case, prior to the applicable date, you will have no obligation to repay any portion of the Retention Award. For purposes of this Agreement, “Change in Control” shall have the meaning ascribed to such term in the Employment Agreement, except that prong (iii)(B) of such definition shall only be triggered upon a complete liquidation or dissolution of the

Company and shall not be triggered upon an agreement for the sale or disposition of all or substantially all of the assets of the Company to any person.

If your employment terminates on or after the Payment Date for any reason and the Release Requirement, to the extent applicable, is not satisfied, then you will, within 30 days after receipt of a request from the Company, repay to the Company the after-tax amount of the Retention Award.

You understand that to the extent applicable, the Bonus Prepayment and the Retention Award remain subject to any applicable compensation clawback or recoupment policy of the Company.

In the event that you do not fulfill any repayment obligation pursuant to this Section 5 during the specified repayment period, you agree that the Company will have the right to offset any such unpaid repayment obligation through the surrender and cancellation of vested shares of Company common stock held by you with a value (as determined by the Company) equal to the amount of such unpaid repayment obligation and, in furtherance of the foregoing, the Company will have the right to take all actions necessary or advisable, including directing any transfer agent, broker or other administrator agent to take all actions necessary or advisable, to effect such surrender and cancellation, and you will not object, and waive any and all rights with respect, to any such surrender and cancellation.

In accordance with the terms of the Employment Agreement, if you resign from employment with the Company with Good Reason, or the Company terminates your employment without Cause, you will be entitled to the Separation Amount (conditioned on you timely signing and returning the Separation Agreement attached as Exhibit A to the Employment Agreement and it becoming effective and irrevocable in accordance with its terms).

The validity, interpretation, construction and performance of this Agreement shall in all respects be governed by the laws of the State of Colorado, without reference to principles of conflict of law.

This Agreement is intended to comply with an exemption from Section 409A of the Code (to the extent applicable) and shall be interpreted, operated and administered accordingly.

This Agreement may be executed in one or more counterparts (including via facsimile and the electronic exchange of .pdf copies), each of which shall be deemed to be an original but all of which together will constitute one and the same agreement.
