SIMON PROPERTY GROUP INC /DE/

1. Organization

Simon Property Group, Inc. is an Indiana corporation that operates as a self-administered and self-managed real estate investment trust, or REIT, under the Internal Revenue Code of 1986, as amended, or the Internal Revenue Code. REITs will generally not be liable for U.S. federal corporate income taxes as long as they distribute not less than 100% of their REIT taxable income. Simon Property Group, L.P. is our majority-owned Indiana partnership subsidiary that owns directly or indirectly all of our real estate properties and other assets. According to the amended and restated Operating Partnership’s partnership agreement, the Operating Partnership is required to pay all expenses of Simon. In these condensed notes to the consolidated financial statements, unless stated otherwise or the context otherwise requires, references to "Simon" mean Simon Property Group, Inc. and references to the "Operating Partnership" mean Simon Property Group, L.P. References to "we," "us" and "our" mean collectively Simon, the Operating Partnership and those entities/subsidiaries owned or controlled by Simon and/or the Operating Partnership. Unless otherwise indicated, these condensed notes to consolidated financial statements apply to both Simon and the Operating Partnership.

As of June 30, 2025, we owned or held an interest in 194 income-producing properties in the United States, which consisted of 92 malls,70 Premium Outlets,14 Mills, six lifestyle centers, and 12 other retail properties in 37 states and Puerto Rico. We also own an 88% noncontrolling interest in the Taubman Realty Group, LLC, or TRG, which has an interest in 22 regional, super-regional, and outlet malls in the U.S. and Asia. Internationally, as of June 30, 2025, we had ownership in 38 Premium Outlets, Designer Outlets, and Luxury Outlet properties primarily located in Asia, Europe, and Canada. As of June 30, 2025, we also owned a 22.4% equity stake in Klépierre SA, or Klépierre, a publicly traded, Paris-based real estate company which owns, or has an interest in, shopping centers located in 14 countries in Europe.

2. Basis of Presentation

The accompanying unaudited consolidated financial statements include the accounts of all controlled subsidiaries, and all significant intercompany amounts have been eliminated. Due to the seasonal nature of certain operational activities, the results for the interim periods are not necessarily indicative of the results to be expected for the full year.

These consolidated financial statements have been prepared in accordance with the instructions to Form 10-Q and include all of the information and disclosures required by accounting principles generally accepted in the United States (GAAP) for interim reporting. Accordingly, they do not include all of the disclosures required by GAAP for complete financial statements. In the opinion of management, all adjustments necessary for a fair presentation (including normal recurring accruals) have been included. The consolidated financial statements in this Form 10-Q should be read in conjunction with the audited consolidated financial statements and related notes contained in the combined 2024 Annual Report on Form 10-K of Simon and the Operating Partnership. Certain reclassifications considered necessary for a fair presentation have been made to the prior period financial statements in order to conform to the current year presentation. These reclassifications have not changed the results of operations.

We consolidate properties that are wholly-owned and properties where we own less than 100% but we control such property. Control of a property is demonstrated by, among other factors, our ability to refinance debt and sell the property without the consent of any other partner or owner and the inability of any other partner or owner to replace us.

We also consolidate a variable interest entity, or VIE, when we are determined to be the primary beneficiary. Determination of the primary beneficiary of a VIE is based on whether an entity has (1) the power to direct activities that most significantly impact economic performance of the VIE and (2) the obligation to absorb losses or the right to receive benefits of the VIE that could potentially be significant to the VIE. Our determination of the primary beneficiary of a VIE considers all relationships between us and the VIE, including management agreements and other contractual arrangements. There have been no changes during 2025 in previous conclusions about whether an entity qualifies as a VIE or whether we are the primary beneficiary of any previously identified VIE. During the periods presented, we did not provide financial or other support to any identified VIE that we were not contractually obligated to provide, except as discussed in Note 6.

Investments in partnerships and joint ventures represent our noncontrolling ownership interests. We account for these unconsolidated entities using the equity method of accounting. We initially record these investments at cost and we subsequently adjust for net equity in income or loss, which we allocate in accordance with the provisions of the applicable partnership or joint venture agreement, cash contributions and distributions, and foreign currency fluctuations, if applicable. The allocation provisions in the partnership or joint venture agreements are not always consistent with the legal ownership interests held by each general or limited partner or joint venture investee primarily due to partner preferences. We separately report investments in partnerships and joint ventures for which accumulated distributions have exceeded investments in and our share of net income of the partnerships and joint ventures within cash distributions and losses in partnerships and joint ventures, at equity in the consolidated balance sheets. The net equity of certain partnerships and joint ventures is less than zero because of financing or operating distributions that are usually greater than net income, as net income includes non-cash charges for depreciation and amortization.

As of June 30, 2025, we consolidated 134 wholly-owned properties and 20 additional properties that are less than wholly-owned, but which we control or for which we are the primary beneficiary. We apply the equity method of accounting to the other 78 properties (the joint venture properties) and our investments in Klépierre, TRG, and our other platform investments. We manage the day-to-day operations of 47 of the 78 joint venture properties, but have determined that our partner or partners have substantive participating rights with respect to the assets and operations of these joint venture properties. Our investments in joint ventures in Japan, South Korea, Indonesia, Mexico, Malaysia, Thailand, Canada, Spain, and the United Kingdom comprise 25 of the remaining 31 properties. These international properties and TRG are managed by joint ventures in which we share control.

Preferred distributions of the Operating Partnership are accrued at declaration and represent distributions on outstanding preferred units of partnership interests, or preferred units, and are included in net income attributable to noncontrolling interests. We allocate net operating results of the Operating Partnership after preferred distributions to limited partners and to Simon based on the partners’ respective weighted average ownership interests in the Operating Partnership. Net operating results of the Operating Partnership attributable to limited partners are reflected in net income attributable to noncontrolling interests. Simon’s weighted average ownership interest in the Operating Partnership was 86.5% and 87.0% for the six months ended June 30, 2025 and 2024, respectively. As of June 30, 2025 and December 31, 2024, Simon’s ownership interest in the Operating Partnership was 86.6% and 86.5%, respectively. We adjust the noncontrolling limited partners’ interests at the end of each period to reflect their interest in the net assets of the Operating Partnership.

Preferred unit requirements in the Operating Partnership’s accompanying consolidated statements of operations and comprehensive income represent distributions on outstanding preferred units and are recorded when declared.

3. Significant Accounting Policies

Cash and Cash Equivalents and Short-term Investments

We consider all highly liquid investments purchased with an original maturity of 90 days or less to be cash and cash equivalents. Cash equivalents are carried at cost, which approximates fair value. Cash equivalents generally consist of commercial paper, bankers’ acceptances, Eurodollars, repurchase agreements, and money market deposits or securities. Financial instruments that potentially subject us to concentrations of credit risk include our cash and cash equivalents and our trade accounts receivable. We place our cash and cash equivalents with institutions of high credit quality. However, at certain times, such cash and cash equivalents are in excess of Federal Deposit Insurance Corporation and Securities Investor Protection Corporation insurance limits.

We classify short-term investments, which consist of time-deposits with original maturities in excess of 90 days as available-for-sale. Short-term investments are reported at fair value and reviewed periodically for allowances for credit losses and impairment. When evaluating the investments, we review factors such as the extent to which the fair value of the security is less than the amortized cost basis, adverse conditions specifically related to the security, the financial condition of the issuer, the Company’s intent to sell, and whether it would be more likely than not that the Company would be required to sell the investments before the recovery of their amortized cost basis.

Equity Instruments and Debt Securities

Equity instruments and debt securities consist primarily of equity instruments, our deferred compensation plan investments, the debt securities of our captive insurance subsidiary, and certain investments held to fund the debt service requirements of debt

previously secured by investment properties. At June 30, 2025 and December 31, 2024, we had equity instruments with readily determinable fair values of $34.4 million and $89.9 million, respectively. Changes in the fair value of these equity instruments are recorded in unrealized (losses) gains in fair value of publicly traded equity instruments and derivative instrument, net in our consolidated statements of operations and comprehensive income. At June 30, 2025 and December 31, 2024, we had equity instruments without readily determinable fair values of $433.9 million and $408.9 million, respectively, for which we have elected the measurement alternative. We regularly evaluate these investments for any impairment in their estimated fair value, as well as any observable price changes for an identical or similar equity instrument of the same issuer, and determined that no material adjustment in the carrying value was required for the three or six months ended June 30, 2025 and 2024.

Our deferred compensation plan equity instruments are valued based upon quoted market prices. The investments have a matching liability as the amounts are fully payable to the employees that earned the compensation. Changes in value of these securities and changes to the matching liability to employees are both recognized in earnings and, as a result, there is no impact to consolidated net income.

At June 30, 2025 and December 31, 2024, we held debt securities of $109.1 million and $133.4 million, respectively, in our captive insurance subsidiary. The types of securities included in the investment portfolio of our captive insurance subsidiary are typically U.S. Treasury or other U.S. government securities as well as corporate debt securities with maturities ranging from less thanone year toten years. These securities are classified as available-for-sale and are valued based upon quoted market prices or other observable inputs when quoted market prices are not available. The amortized cost of debt securities, which approximates fair value, held by our captive insurance subsidiary is adjusted for amortization of premiums and accretion of discounts to maturity. Changes in the values of these securities are recognized in accumulated other comprehensive loss until the gain or loss is realized or until any unrealized loss is deemed to be other-than-temporary. We review any declines in value of these securities for other-than-temporary impairment and consider the severity and duration of any decline in value. To the extent an other-than-temporary impairment is deemed to have occurred, an impairment is recorded and a new cost basis is established.

Our captive insurance subsidiary is required to maintain statutory minimum capital and surplus as well as maintain a minimum liquidity ratio. Therefore, our access to these securities may be limited.

Fair Value Measurements

Level 1 fair value inputs are quoted prices for identical items in active, liquid and visible markets such as stock exchanges. Level 2 fair value inputs are observable information for similar items in active or inactive markets, and appropriately consider counterparty creditworthiness in the valuations. Level 3 fair value inputs reflect our best estimate of inputs and assumptions market participants would use in pricing an asset or liability at the measurement date. The inputs are unobservable in the market and significant to the valuation estimate. We haveno investments for which fair value is measured on a recurring basis using Level 3 inputs.

We have equity instruments with readily determinable fair values that are valued using Level 1 inputs. We have foreign currency forward contracts, interest rate cap and swap agreements that are valued using Level 2 inputs. We also have a bifurcated embedded derivative option that was a component of the €750.0 million exchangeable bonds issued in November 2023. This instrument is classified as primarily having Level 3 inputs and is further discussed in Note 3, within the Derivative Financial Instruments subsection and in Note 7.

Note 7 includes a discussion of the fair value of debt measured using Level 2 inputs. Notes 3, 4, and 6 include discussions of the fair values recorded in purchase accounting using Level 2 and Level 3 inputs. Level 3 inputs to our purchase accounting and impairment analyses include our estimations of fair value, net operating results of the property, capitalization rates and discount rates.

Noncontrolling Interests

Simon

Details of the carrying amount of our noncontrolling interests are as follows:

Net income attributable to noncontrolling interests (which includes nonredeemable and redeemable noncontrolling interests in consolidated properties, limited partners’ interests in the Operating Partnership and preferred distributions payable by the Operating Partnership on its outstanding preferred units) is a component of consolidated net income. In addition, the individual components of other comprehensive income (loss) are presented in the aggregate for both controlling and noncontrolling interests, with the portion attributable to noncontrolling interests deducted from comprehensive income attributable to common stockholders.

Our evaluation of the appropriateness of classifying the Operating Partnership’s common units of partnership interest, or units, held by Simon and the Operating Partnership's limited partners within permanent equity considered several significant factors. First, as a limited partnership, all decisions relating to the Operating Partnership’s operations and distributions are made by Simon, acting as the Operating Partnership’s sole general partner. The decisions of the general partner are made by Simon's Board of Directors or management. The Operating Partnership has no other governance structure. Secondly, the sole asset of Simon is its interest in the Operating Partnership. As a result, a share of common stock of Simon, or common stock, if owned by the Operating Partnership, is best characterized as being similar to a treasury share and thus not an asset of the Operating Partnership.

Limited partners of the Operating Partnership have the right under the Operating Partnership’s partnership agreement to exchange their units for shares of common stock or cash, as selected by Simon as the sole general partner. Accordingly, we classify units held by limited partners in permanent equity because Simon may elect to issue shares of common stock to limited partners exercising their exchange rights rather than using cash. Under the Operating Partnership’s partnership agreement, the Operating Partnership is required to redeem units held by Simon only when Simon has repurchased shares of common stock. We classify units held by Simon in permanent equity because the decision to redeem those units would be made by Simon.

Net income attributable to noncontrolling interests (which includes nonredeemable and redeemable noncontrolling interests in consolidated properties) is a component of consolidated net income.

Accumulated Other Comprehensive Income (Loss)

Simon

The total accumulated other comprehensive income (loss) related to Simon’s currency translation adjustment was ($283.7) million and ($250.2) million as of June 30, 2025 and December 31, 2024, respectively.

The reclassifications out of accumulated other comprehensive income (loss) consisted of the following:

The total accumulated other comprehensive income (loss) related to the Operating Partnership’s currency translation adjustment was ($327.8) million and ($289.1) million as of June 30, 2025 and December 31, 2024, respectively.

The reclassifications out of accumulated other comprehensive income (loss) consisted of the following:

Derivative Financial Instruments

We record all derivatives on our consolidated balance sheets at fair value. The accounting for changes in the fair value of derivatives depends on the intended use of the derivative, whether we have designated a derivative as a hedge and whether the hedging relationship has satisfied the criteria necessary to apply hedge accounting. We may use a variety of derivative financial instruments in the normal course of business to selectively manage or hedge a portion of the risks associated with our indebtedness and interest payments. Our objectives in using interest rate derivatives are to add stability to interest expense and to manage our exposure to interest rate movements. To accomplish this objective, we primarily use interest rate swaps and caps. We require that hedging derivative instruments be highly effective in reducing the risk exposure that they are designated to hedge. We formally designate any instrument that meets these hedging criteria as a hedge at the inception of the derivative contract. We haveno credit-risk-related hedging or derivative activities.

As of June 30, 2025, we had the following outstanding interest rate derivatives related to managing our interest rate risk:

As of December 31, 2024, we had the following outstanding interest rate derivatives related to managing our interest rate risk:

The carrying value of our interest rate swap and cap agreements, at fair value, are included in deferred costs and other assets and other liabilities. As of June 30, 2025, we had interest rate swap and cap agreements with combined asset balances of $3.5 million and combined liability balances of $2.7 million. As of December 31, 2024, we had interest rate swap and cap agreements with combined asset balances of $8.3 million and combined liability balances of $2.2 million.

Our exposure to market risk due to changes in interest rates primarily relates to our long-term debt obligations. We manage exposure to interest rate market risk through our risk management strategy by a combination of interest rate protection agreements to effectively fix or cap a portion of variable rate debt.

We may enter into treasury lock agreements as part of an anticipated debt issuance. Upon completion of the debt issuance, the fair value of these instruments that had been recorded as part of accumulated other comprehensive income (loss) is amortized to interest expense over the life of the debt agreement.

The unamortized gain on our treasury locks and terminated hedges recorded in accumulated other comprehensive income (loss) was $37.9 million and $40.8 million as of June 30, 2025 and December 31, 2024, respectively. Within the next 12 months, we expect to reclassify to earnings approximately $5.8 million of gains related to terminated interest rate swaps from the current balance held in accumulated other comprehensive income (loss).

We are also exposed to foreign currency risk on financings of certain foreign operations. Our intent is to offset gains and losses that occur on the underlying exposures, with gains and losses on the derivative contracts hedging these exposures. We do not enter into either interest rate protection or foreign currency rate protection agreements for speculative purposes.

We are also exposed to fluctuations in foreign exchange rates on financial instruments which are denominated in foreign currencies, primarily in Yen and Euro. Related to our Euro exposures, we use currency forward contracts, cross currency swap contracts and foreign currency denominated debt to manage our exposure to changes in foreign exchange rates on certain Euro-denominated receivables and net investments. Currency forward contracts involve fixing primarily the Euro:USD exchange rate for delivery of a specified amount of foreign currency on a specified date. The currency forward contracts are typically cash settled in U.S. dollars for their fair value at or close to their settlement date.

We had the following Euro:USD forward contracts designated as net investment hedges at June 30, 2025 and December 31, 2024 (in millions):

Asset balances in the above table are included in deferred costs and other assets. Liability balances in the above table are included in other liabilities.

We have designated certain derivative and nonderivative instruments as net investment hedges. Accordingly, we report the changes in fair value in other comprehensive income (loss). For the six months ended June 30, 2025 and 2024, we recorded gains of $164.5 million and $60.7 million, respectively, in the cumulative translation adjustment section of the other comprehensive income (loss). Changes in the value of these instruments are offset by changes in the underlying hedged Euro-denominated joint venture investments.

The total accumulated other comprehensive income (loss) related to Simon’s derivative activities, including our share of other comprehensive income (loss) from unconsolidated entities, was $27.3 million and $57.9 million as of June 30, 2025 and December 31, 2024, respectively. The total accumulated other comprehensive income (loss) related to the Operating Partnership’s derivative activities, including our share of other comprehensive income (loss) from unconsolidated entities, was $31.6 million and $66.9 million as of June 30, 2025 and December 31, 2024, respectively.

The exchange option of our exchangeable bonds is valued as a derivative liability using an option pricing model that incorporates the observed period ending price of the exchangeable bonds and secondary market prices of comparable unsecured senior notes without an exchange feature. The key assumptions utilized are the period ending share-price of Klépierre, share-price implied volatility, the EUR risk-free rate, Klépierre expected dividend yield, time to maturity, and the comparable spread to the EUR risk-free rate of unsecured senior notes without an exchange feature.

The fair value of the option is recorded in other liabilities in the consolidated balance sheets and changes to the value of the option are recognized in the consolidated statements of operations and comprehensive income in unrealized (losses) gains in fair value of publicly traded equity instruments and derivative instrument, net.

The key inputs into the option model for the exchange option within the exchangeable bonds as of June 30, 2025 and December 31, 2024 were as follows:

The option is measured at fair value on a recurring basis. As of June 30, 2025 and December 31, 2024 the values of the option were$190.5 million and$60.0 million, respectively.

New Accounting Pronouncements

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting,” which provides improvements to reportable segment disclosures, primarily through enhanced disclosures about significant segment expenses. The standard became effective for us for fiscal years beginning after December 15, 2023 and is effective for interim periods within fiscal years beginning after December 15, 2024. Refer to Note 11.

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 will be effective for us for the fiscal years beginning after December 15, 2024 on a prospective basis. We are currently evaluating the impact that the adoption of the new standard will have on our consolidated financial statements and footnotes.

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.

4. Real Estate Acquisitions and Dispositions

Unless otherwise noted, gains and losses on property transactions are included in 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 the six months ended June 30, 2025 and 2024.

2025 Acquisitions

On June 27, 2025, we acquired the remaining 75% interest in the retail component and 100% of the parking component of Brickell City Centre, resulting in the consolidation of the retail component which had previously been accounted for under the equity method. The cash consideration for this transaction, including working capital, was $497.7 million. Cash acquired was $24.0 million. Upon consolidation, we recorded $544.6 million of investment property and lease intangible assets. The property is unencumbered. We accounted for this transaction as an asset acquisition and these non-cash investing activities are excluded from our consolidated statement of cash flows.

On April 1, 2025, we acquired the remaining 50% interest in Briarwood Mall from a joint venture partner, resulting in the consolidation of this property. The cash consideration for this transaction, including working capital, was $9.2 million. Cash acquired was $14.7 million. Upon consolidation, we recorded $168.6 million of investment property. The property is subject to a $165 million 3.29% fixed rate mortgage loan.

The property was subject to a $160.8 million 8.10% variable rate mortgage loan. This mortgage loan was paid off prior to December 31, 2024. We accounted for this transaction as an asset acquisition and these non-cash investing and financing activities are excluded from our statement of cash flows.

On February 6, 2024, we acquired an additional interest in Miami International Mall from a joint venture partner, resulting in the consolidation of this property. The cash consideration for this transaction was de minimis. Upon consolidation, we recorded $102.5 million of investment property. The property is subject to a $158.0 million 6.92% fixed rate mortgage loan. We accounted for this transaction as an asset acquisition and these non-cash investing and financing activities are excluded from our statement of cash flows.

2024 Dispositions

During 2024, we disposed of our interests intwo consolidated retail properties. The combined proceeds from these transactions were $55.2 million, resulting in a net loss of $67.2 million.

5. Per Share and Per Unit Data

We determine basic earnings per share and basic earnings per unit based on the weighted average number of shares of common stock or units, as applicable, outstanding during the period and we consider any participating securities for purposes of

applying the two-class method. We determine diluted earnings per share and diluted earnings per unit based on the weighted average number of shares of common stock or units, as applicable, outstanding combined with the incremental weighted average number of shares or units, as applicable, that would have been outstanding assuming all potentially dilutive securities were converted into shares of common stock or units, as applicable, at the earliest date possible. The following tables set forth the components of basic and diluted earnings per share and basic and diluted earnings per unit.

Simon

For the six months ended June 30, 2025, potentially dilutive securities include units that are exchangeable for common stock and long-term incentive performance units, or LTIP units, granted under our long-term incentive performance programs that are convertible into units and exchangeable for common stock. No securities had a material dilutive effect for the six months ended June 30, 2025 and 2024. We have not adjusted net income attributable to common stockholders and weighted average shares outstanding for income allocable to limited partners or units, respectively, as doing so would have no dilutive impact. We accrue dividends when they are declared.

For the six months ended June 30, 2025, potentially dilutive securities include LTIP units. No securities had a material dilutive effect for the six months ended June 30, 2025 and 2024. We accrue distributions when they are declared.

6. Investment in Unconsolidated Entities and International Investments

Real Estate Joint Ventures and Investments

Joint ventures are common in the real estate industry. We use joint ventures to finance properties, develop new properties and diversify our risk in a particular property or portfolio of properties. As discussed in note 2, we held joint venture interests in 78 properties as of June 30, 2025.

Certain of our joint venture properties are subject to various rights of first refusal, buy-sell provisions, put and call rights, or other sale or marketing rights for partners which are customary in real estate joint venture agreements and the industry. We and our partners in these joint ventures may initiate these provisions (subject to any applicable lock up or similar restrictions), which may result in either the sale of our interest or the use of available cash or borrowings, or the use of limited partnership interests in the Operating Partnership, to acquire the joint venture interest from our partner.

We may provide financing to joint venture properties primarily in the form of interest bearing loans. As of June 30, 2025 and December 31, 2024, we had construction loans and other advances to these related parties totaling $56.1 million and $59.6 million, respectively, which are included in deferred costs and other assets in the accompanying consolidated balance sheets.

Taubman Realty Group

During the fourth quarter of 2024, we acquired an additional 4% ownership in TRG for approximately $266.7 million by issuing 1,572,500 units in the Operating Partnership, bringing our noncontrolling ownership interest in TRG to 88%. Substantially all our investment has been determined to relate to investment property. Our investment includes 6.38% Series A Cumulative Redeemable Preferred Units for $362.5 million issued to us. The transaction did not include or result in any change to the rights and obligations or decision-making authority of the members of the TRG partnership. Under the terms of the TRG partnership agreement, there is no change to the governance, decision-making or other rights of members unless our ownership in the TRG partnership exceeds 92.0%. As with all of our unconsolidated investments, we continuously reassess our consolidation conclusions both in terms of any contractual changes, as well as by evaluating how the members substantively conduct their rights and obligations contained within the relevant partnership agreements.

The table below represents summary financial information of TRG.

Other Platform Investments

During the fourth quarter of 2024, J.C. Penney completed an all-equity transaction where it acquired the retail operations of SPARC Group, resulting in the recognition of a non-cash pre-tax gain, our share of which was $100.5 million. The combined business was renamed Catalyst post transaction. In connection with this transaction, we recorded deferred taxes of $25.1 million. As of June 30, 2025, we own a 31.3% noncontrolling interest in Catalyst. Additionally, we continue to hold a 33.3% noncontrolling interest in SPARC Holdings, the former owner of SPARC Group, which now primarily holds a 25% interest in Catalyst. During 2025, Catalyst recognized a net pre-tax gain on merger-related activities primarily because of the deconsolidation of Forever 21, our share of which was $80.5 million, which is included in Gain due to disposal, exchange, or revaluation of equity interests, net in the consolidated statement of operations and comprehensive income.

During the first quarter of 2024, we and a partner funded a loan to SPARC Group, our share of which was $100.0 million, which constituted a reconsideration event and the resulting determination that SPARC Group was a VIE. As we did not have power to direct the activities that most significantly impact the economic performance of SPARC Group, we were not the primary beneficiary and continued to account for our investment under the equity method. In the second quarter of 2024, we were reimbursed $50.0 million by a venture partner, reducing our loan receivable to $50.0 million and equalizing all partners’ loans to the venture. We had previously provided a guarantee to SPARC Group’s lenders of $50.0 million, however as a result of the Catalyst transaction discussed above, this guarantee has been cancelled and, accordingly, we have determined SPARC Group is no longer a VIE.

During the second quarter of 2024, we participated in the formation of a joint venture, Phoenix Retail, LLC, to acquire the Express Retail Company and operate Express and Bonobos direct-to-consumer businesses in the United States, from the previous owner on June 21, 2024, in a bankruptcy proceeding. There wasno cash consideration transferred for our 39.4% noncontrolling interest and non-cash consideration was de minimis.

During the first quarter of 2024, we sold all of our remaining interest in Authentic Brands Group, or ABG, for cash proceeds of $1.2 billion, resulting in a pre-tax gain of $414.8 million, which is included in gain on disposal, exchange, or revaluation of equity interests, net, in the consolidated statement of operations. In connection with this transaction, we recorded tax expense of $103.7 million, which is included in income and other tax benefit expense in the consolidated statement of operations and comprehensive income.

As of June 30, 2025, we own a 45% noncontrolling interest in Rue Gilt Groupe and a 50% noncontrolling legal ownership interest in Jamestown.

The table below represents combined summary financial information, after intercompany eliminations, of our other platform investments.

European Investments

At June 30, 2025, we owned 63,924,148 shares, or approximately 22.4%, of Klépierre, which had a quoted market price of $39.27 per share.

Mortgage Debt

Total mortgage indebtedness was $5.3 billion and $5.0 billion at June 30, 2025 and December 31, 2024, respectively.

Covenants

Our unsecured debt agreements contain financial covenants and other non-financial covenants. The Credit Facilities contain ongoing covenants relating to total and secured leverage to capitalization value, minimum earnings before interest, taxes, depreciation, and amortization, or EBITDA, and unencumbered EBITDA coverage requirements. Payment under the Credit Facilities can be accelerated if the Operating Partnership or Simon is subject to bankruptcy proceedings or upon the occurrence of certain other events. If we were to fail to comply with these covenants, after the expiration of the applicable cure periods, the debt maturity could be accelerated or other remedies could be sought by the lender, including adjustments to the applicable interest rate. As of June 30, 2025, we were in compliance with all covenants of our unsecured debt.

At June 30, 2025, our consolidated subsidiaries were the borrowers under 36 non-recourse mortgage notes secured by mortgages on 39 properties and other assets, includingtwo separate pools of cross-defaulted and cross-collateralized mortgages encumbering a total offive properties. Under these cross-default provisions, a default under any mortgage included in the cross-defaulted pool may constitute a default under all mortgages within that pool and may lead to acceleration of the indebtedness due on each property within the pool. Certain of our secured debt instruments contain financial and other non-financial covenants which are specific to the properties that serve as collateral for that debt. If the applicable borrower under these non-recourse mortgage notes were to fail to comply with these covenants, the lender could accelerate the debt and enforce its rights against their collateral. At June 30, 2025, the applicable borrowers under these non-recourse mortgage notes were in compliance with all covenants where non-compliance could individually or in the aggregate, giving effect to applicable cross-default provisions, have a material adverse effect on our financial condition, liquidity or results of operations.

Fair Value of Debt

The carrying value of our variable-rate mortgages and other loans approximates their fair values. We estimate the fair values of consolidated fixed rate mortgages using cash flows discounted at current borrowing rates and other indebtedness using cash flows discounted at current market rates. We estimate the fair values of consolidated fixed rate unsecured notes using quoted market prices, or, if no quoted market prices are available, we use quoted market prices for securities with similar terms and maturities. The book value of our consolidated fixed rate mortgages and unsecured indebtedness including commercial paper was

$24.4 billion and $24.0 billion as of June 30, 2025 and December 31, 2024, respectively. The fair values of these financial instruments and the related discount rate assumptions as of June 30, 2025 and December 31, 2024 are summarized as follows:

8. Equity

During the six months ended June 30, 2025, Simon issued 116,558 shares of common stock totwo limited partners of the Operating Partnership in exchange for an equal number of units pursuant to the partnership agreement of the Operating Partnership. During the six months ended June 30, 2025, the Operating Partnership redeemed 36,591 units from three limited partners for $6.4 million. These transactions increased Simon’s ownership interest in the Operating Partnership.

On February 8, 2024, Simon's Board of Directors authorized a new common stock repurchase plan which immediately replaced the existing repurchase plan. Under the plan, Simon may repurchase up to $2.0 billion of its common stock during thetwo-year period commencing on February 8, 2024 and ending on February 8, 2026 in the open market or in privately negotiated transactions as market conditions warrant. As of June 30, 2025, no shares had been repurchased under the plan. As Simon repurchases shares under the plan, the Operating Partnership repurchases an equal number of units from Simon.

We paid a common stock dividend of $2.10 per share for the second quarter of 2025, and $4.20 per share for the six months ended June 30,2025. We paid common stock dividends of $3.95 per share for the six months ended June 30,2024. The Operating Partnership paid distributions per unit for the same amounts. On August 4, 2025, Simon’s Board of Directors declared a quarterly cash dividend for thethird quarter of 2025 of $2.15 per share, payable on September 30, 2025 to shareholders of record on September 9, 2025. Thedistribution rate on units is equal to the dividend rate on common stock.

Temporary Equity

Simon

Simon classifies as temporary equity those securities for which there is the possibility that Simon could be required to redeem the security for cash irrespective of the probability of such a possibility. As a result, Simon classifiesone series of preferred units in the Operating Partnership and noncontrolling redeemable interests in properties in temporary equity. Each of these securities is discussed further below.

Limited Partners’ Preferred Interest in the Operating Partnership and Noncontrolling Redeemable Interests in Properties. The redemption features of the preferred units in the Operating Partnership contain provisions which could require the Operating Partnership to settle the redemption in cash. As a result, this series of preferred units in the Operating Partnership remains classified outside permanent equity. The remaining interests in a property or portfolio of properties which are redeemable at the option of the holder or in circumstances that may be outside Simon’s control are accounted for as temporary equity. The carrying amount of the noncontrolling interest is adjusted to the redemption amount assuming the instrument is redeemable at the balance sheet date. Changes in the redemption value of the underlying noncontrolling interest are recorded within accumulated deficit in the consolidated statements of equity in issuance of unit equivalents and other. There wereno noncontrolling interests

redeemable at amounts in excess of fair value as of June 30, 2025 and December 31, 2024. The following table summarizes the preferred units in the Operating Partnership and the amount of the noncontrolling redeemable interests in properties as follows:

Stock-Based Compensation

Our long-term incentive compensation awards under our stock-based compensation plans primarily take the form of LTIP units, restricted stock units, and restricted stock. The substantial majority of these awards are market condition or performance-based, and are based on various market, corporate and business unit performance measures as further described below. The expense related to these programs, net of amounts capitalized, is included within home and regional office costs and general and administrative costs in the accompanying statements of operations and comprehensive income. LTIP units are a form of limited partnership interest issued by the Operating Partnership, which are subject to the participant maintaining employment with us through certain dates and other conditions as described in the applicable award agreements. Awarded LTIP units not earned in accordance with the conditions set forth in the applicable award agreements are forfeited. Earned and fully vested LTIP units are equivalent to units of the Operating Partnership. Participants are entitled to receive distributions on the awarded LTIP units, as defined, equal to 10% of the regular quarterly distributions paid on a unit of the Operating Partnership. As a result, we account for these LTIP units as participating securities under the two class method of computing earnings per share. These are granted under The Simon Property Group, L.P. 2019 Stock Incentive Plan, or the 2019 Plan.

The grant date fair values of any LTIP units that are market-based awards are estimated using a Monte Carlo model, and the resulting fixed expense is recorded regardless of whether the market condition criteria are achieved if the participant performs the required service period. The grant date fair values of the market-based awards are being amortized into expense over the performance period, which is the grant date through the date at which the awards, if earned, become vested. The expense of the performance-based award is recorded over the performance period, which is the grant date through the date at which the awards, if earned, become vested, based on our assessment as to whether it is probable that the performance criteria will be achieved during the applicable performance periods. The grant date fair values of any restricted stock unit awards are recognized as expense over the vesting period.

In connection with rent deferrals or other accruals of unpaid rent payments, if we determine that rent payments are probable of collection, we will continue to recognize lease income on a straight-line basis over the lease term along with associated tenant receivables. However, if we determine that such deferred rent payments or other accrued but unpaid rent payments are not probable of collection, lease income will be recorded on the cash basis, with the corresponding tenant receivable and deferred rent receivable balances charged as a direct write-off against lease income in the period of the change in our collectability determination. Additionally, our assessment of collectability incorporates information regarding a tenant’s financial condition that is obtained from available financial data, the expected outcome of contractual disputes and other matters, and our communications and negotiations with the tenant.

When a tenant seeks to reorganize its operations through bankruptcy proceedings, we assess the collectability of receivable balances. Our ongoing assessment incorporates, among other things, the timing of a tenant’s bankruptcy filing and our expectations of the assumptions by the tenant in bankruptcy proceedings of leases at the Company’s properties on substantially similar terms.

Litigation

We are involved from time-to-time in various legal and regulatory proceedings that arise in the ordinary course of our business, including, but not limited to, commercial disputes, environmental matters, and litigation in connection with transactions such as acquisitions and divestitures. We believe that current proceedings will not have a material adverse effect on our financial condition, liquidity or results of operations. We record a liability when a loss is considered probable and the amount can be reasonably estimated.

Lease Commitments

As of June 30, 2025, we are subject to ground leases that cover all or a portion of 23 of our consolidated properties with termination dates extending through 2090, including periods for which exercising an extension option is reasonably assured. These ground leases generally require us to make fixed annual rental payments, or a fixed annual rental payment plus a percentage rent component based upon the revenues or total reported sales of the property. In addition, we have several regional office locations that are subject to leases with termination dates ranging from 2025 to 2034. These office leases generally require us to make fixed annual rental payments plus pay our share of common area, real estate taxes, and utility expenses. Some of our ground and office leases include escalation clauses. All of our lease arrangements are classified as operating leases. We incurred ground lease expense and office lease expense, which are included in other expense and home office and regional expense, respectively, as follows:

Minimum lease payments due under these leases for years ending December 31, excluding applicable extension options and renewal options unless reasonably certain of exercise and any sublease income, are as follows:

Guarantees of Indebtedness

Joint venture debt is the liability of the joint venture and is typically secured by the joint venture property, which is non-recourse to us. In addition to the guarantee disclosed in Note 6, as of June 30, 2025 and December 31, 2024, the Operating Partnership guaranteed joint venture related mortgage indebtedness of$122.0 million and$109.8 million, respectively. Mortgages guaranteed by the Operating Partnership are secured by the property of the joint venture which could be sold in order to satisfy the outstanding obligation and which has an estimated fair value in excess of the guaranteed amount.

Concentration of Credit Risk

Our U.S. Malls, Premium Outlets, and The Mills rely upon anchor tenants to attract customers; however, anchors do not contribute materially to our financial results as many anchors own their spaces. No customer or tenant accounts for 5% or more of our consolidated revenues.

11. Segments and Geographic Locations

Our primary business is the ownership, development and management of premier shopping, dining, entertainment and mixed-use destinations, which consist primarily of malls, Premium Outlets, and The Mills. We identify our operating segments based on how our chief operating decision maker (“CODM”) allocates resources, assesses performance, and makes decisions. Our CODM is our President and Chief Executive Officer who is actively involved in all aspects of the portfolio operations. We have aggregated our consolidated real estate operations, including malls, Premium Outlets, The Mills, and our consolidated international real estate operations intoone reportable segment because they have similar economic characteristics and we provide similar products and services to similar types of, and in many cases, the same, tenants. Revenue earned from these segment operations represents substantially all of lease income reported on the consolidated statements of operations and comprehensive income, all of which is generated from external customers, with the exception of eliminations made to remove our share of lease income earned from tenants in which we have an ownership interest. The primary financial measure the CODM uses to measure the operating performance of the consolidated real estate operations is net operating income (“NOI”), which is reconciled to consolidated net income below. The Company believes that NOI is helpful to investors as a measure of operating performance because it is a direct measure of the actual operating results of the Company’s properties and because it is a widely recognized measure of the performance of REITs providing a relevant basis for comparison among REITs. Non-segment revenue includes Management Fees and Other revenues, described earlier in Note 3, and the majority of Other income, which primarily includes interest income and miscellaneous activities such as land sales, dividends received from certain investments and other activities as disclosed through these notes to the extent material, as well as eliminations. None of our unconsolidated investments meet the materiality threshold required for separate reporting as a reportable segment, though we have included disclosures related to the activities of these investments in Note 6. Approximately 95% of total consolidated assets, with the exception of our investment in Klépierre, TRG and other unconsolidated entities and certain other assets, are attributable to our real estate segment.

As of June 30, 2025 and 2024, approximately 9.3% and 7.1%, respectively, of our consolidated long-lived assets were located outside the United States and as of June 30, 2025 and 2024, approximately 5.1% and 4.3%, respectively, of our consolidated total revenues were derived from assets located outside the United States. Substantially all of our capital expenditures reported in the consolidated statements of cash flows relate to our segment operations.

The following table reconciles our reportable segment to net income:
