2025 SIMON® Annual Report

depreciation and amortization during the anticipated holding period plus its residual value is less than the carrying value of the property. To the extent impairment has occurred, we charge to income the excess of carrying value of the property over our estimate of its fair value. We also review our investments, including investments in unconsolidated entities, to identify and evaluate whether events or changes in circumstances indicate that the carrying amount of our investments may not be recoverable. We will record an impairment charge if we determine the fair value of the investments are less than their carrying value and such impairment is other-than-temporary. Our evaluation of changes in economic or operating conditions and whether an impairment is other-than- temporary may include developing estimates of fair value, forecasted cash flows or operating income before depreciation and amortization. We estimate undiscounted cash flows and fair value, if applicable, using observable and unobservable data such as operating income, hold periods, estimated capitalization rates, or relevant market multiples, leasing prospects and local market information and whether certain impairments are other-than-temporary. Changes in economic and operating conditions, including changes in the financial condition of our tenants, and changes to our intent and ability to hold the related asset, that occur subsequent to our review of recoverability of investment property and other investments could impact the assumptions used in that assessment and could result in future charges to earnings if assumptions regarding those investments differ from actual results. • To maintain Simon’s status as a REIT, Simon must distribute at least 90% of its REIT taxable income in any given year and meet certain asset and income tests. We monitor our business and transactions that may potentially impact Simon’s REIT status. In the unlikely event that we fail to maintain Simon’s REIT status, and available relief provisions do not apply, Simon would be required to pay U.S. federal income taxes at regular corporate income tax rates during the period Simon did not qualify as a REIT. If Simon lost its REIT status, it could not elect to be taxed as a REIT for four taxable years following the year during which qualification was lost unless its failure was due to reasonable cause and certain other conditions were met. As a result, failing to maintain REIT status would result in a significant increase in the income tax expense recorded and paid during those periods. • In the period of a significant acquisition of real estate, we make estimates as part of our valuation of the purchase price of asset acquisitions (including the components of excess investment in joint ventures) and business combinations to the various components of the acquisition based upon the fair value of each component. The most significant components of our real estate valuations are typically the determination of fair value to the buildings as-if-vacant, land and market value of in-place leases. In the case of the fair value of buildings and fair value of land and other intangibles, our estimates of the values of these components will affect the amount of depreciation or amortization we record over the estimated useful life of the property acquired or the remaining lease term. In the case of the market value of in-place leases, we make our best estimates of the tenants’ ability to pay rents based upon the tenants’ operating performance at the property, including the competitive position of the property in its market as well as sales psf, rents psf, and overall occupancy cost for the tenants in place at the acquisition date. Our assumptions affect the amount of future revenue that we will recognize over the remaining lease term for the acquired in-place leases. Results of Operations The following acquisitions, dispositions, and openings of consolidated properties affected our consolidated results in the comparative periods: • On November 17, 2025, we acquired a 100% interest in a retail property, Phillips Place, a 132,805 square foot center in Charlotte, North Carolina. • On October 31, 2025, we closed on the acquisition of the remaining 12% interest in TRG which we did not previously own. As a result of this acquisition, we obtained control of and consolidated TRG as of the acquisition date. TRG has an interest in 22 regional, super-regional, and outlet malls in the U.S. and Asia, 11 of which are now consolidated and 11 of which are accounted for under the equity method upon the acquisition. • On June 27, 2025, we acquired the remaining interest in the retail component and 100% of the parking component of Brickell City Centre, resulting in the consolidation of the retail component of this property. • On April 1, 2025, we acquired the remaining interest in Briarwood Mall from a joint venture partner, resulting in the consolidation of this property.
