PART III — NARRATIVE

As previously disclosed by Apartment Investment and Management Company and Aimco OP L.P. (collectively, “Aimco” or the “Company”), on December 15, 2020, the Company completed the previously announced separation of its businesses (the “Separation”), creating two, separate and distinct, companies, Aimco and Apartment Income REIT Corp.

The Annual Report on Form 10-K for the year ended December 31, 2020 will be the Company’s first annual report subsequent to the Separation. Due to the timing of the Separation, the complexity associated with preparing the Company’s financial statements predominately on a carve out basis in accordance with US GAAP and the complexity of accounting for certain assets and liabilities obtained in the Separation, management of the Company has determined that it requires additional time to complete its review of the Company’s financial statements and other disclosures in the Form 10-K. The Company is therefore unable to file its 2020 Annual Report on Form 10-K within the prescribed time without unreasonable effort or expense. The Company intends to file its 2020 Form 10-K no later than the fifteenth calendar day after its prescribed due date.
