Simon Property Group, Inc. Simon Property Group, L.P. Notes to Consolidated Financial Statements (Dollars in thousands, except share, per share, unit and per unit amounts and where indicated as in millions or billions)

In December 2023, the FASB issued ASU 2023-09, “Income Taxes,” which provides improvements to annual income tax disclosures by enhancing the transparency and decision usefulness of the material provided. The standard is effective for us for fiscal years beginning after December 15, 2024 on a prospective basis. Refer to the Income Taxes disclosure in Note 3. In November 2024, the FASB issued ASU 2024-03, “Income Statement – Reporting Comprehensive Income – Expense Disaggregation Disclosures,” to improve the disclosures about a public business entity’s expenses by providing more detailed information about the types of expenses in commonly presented expense captions. The standard will be effective for us for fiscal years beginning after December 15, 2026 and interim periods within fiscal years beginning after December 15, 2027. We are currently evaluating the impact that the adoption of this new standard will have on our consolidated financial statements and footnotes. In December 2025, the FASB issued ASU 2025-11, “Interim Reporting,” which is intended to improve the navigability of the required interim reporting disclosures and clarifies when that guidance is applicable. The amendments in the ASU will be effective for us for interim reporting periods within annual reporting periods beginning after December 15, 2027. We are currently evaluating the impact that the adoption of these amendments will have on our footnotes. 4. Real Estate Acquisitions and Dispositions We acquire interests in properties to generate both current income and long-term appreciation in value. We acquire interests in individual properties or portfolios of real estate companies that meet our investment criteria and sell properties which no longer meet our strategic criteria. Unless otherwise noted below, gains and losses on these transactions are included in (Loss) gain on acquisition of controlling interest, sale or disposal of, or recovery on, assets and interests in unconsolidated entities and impairment, net in the accompanying consolidated statements of operations and comprehensive income. We capitalize asset acquisition costs and expense costs related to business combinations, as well as disposition related costs as they are incurred. We incurred a minimal amount of transaction expenses during 2025, 2024, and 2023. Refer to Note 6 for disclosure of unconsolidated joint venture acquisitions and dispositions. Our acquisition and disposition activity for the periods presented are as follows: 2025 Acquisitions On November 17, 2025, we completed the acquisition of a 100% interest in a retail property, Phillips Place, located in Charlotte, North Carolina. The cash consideration including working capital was $143.8 million. Upon acquisition, we recorded $133.3 million of investment property. The property is unencumbered. We accounted for this transaction as an asset acquisition. On October 31, 2025, we closed on the acquisition of the remaining 12% interest in TRG which we did not previously own in exchange for approximately 5.06 million units in the Operating Partnership. 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. The 11 consolidated properties are now reported within our Real estate segment in Note 11. This acquisition aligns with our strategy of owning high-quality assets, unlocking operational synergies and driving further innovation. The acquisition was accounted for as a business combination requiring a remeasurement of our previously held 88% noncontrolling equity interest to fair value, which resulted in the recognition of a non-cash gain of $2.858 billion in the fourth quarter of 2025, which is included in gain (loss) on acquisition of controlling interest, sale, or disposal of, or recovery on, assets and interests in unconsolidated entities and impairment, net in the consolidated statement of operations and comprehensive income and the assets acquired and liabilities assumed were recognized at their acquisition date fair value. The fair value of our previously held 88% noncontrolling equity interest was measured based primarily on the value implied by our most recent previous purchase of noncontrolling equity interests in TRG discussed in Note 6. We have not yet finalized the valuation of the assets acquired and liabilities assumed as of December 31, 2025.
