Non-GAAP Financial Measures This press release includes FFO, FFO per share, Real Estate FFO, Real Estate FFO per share and domestic and portfolio NOI growth which are financial performance measures not defined by generally accepted accounting principles in the United States (“GAAP”).

EARNINGS RELEASE Forward-Looking Statements Certain statements made in this press release may be deemed “forward-looking statements” within the meaning of the Private Securities Litigation Reform Act of 1995. Although Simon believes the expectations reflected in any forward-looking statements are based on reasonable assumptions, Simon can give no assurance that its expectations will be attained, and it is possible that Simon’s actual results may differ materially from those indicated by these forward-looking statements due to a variety of risks, uncertainties and other factors.

EARNINGS RELEASE Simon Property Group, Inc. Footnotes to Unaudited Financial Information Notes: (A) Excess investment represents the unamortized difference of our investment over equity in the underlying net assets of the related partnerships and joint ventures shown therein. The Company generally amortizes excess investment over the life of the related assets. (B) The Unaudited Joint Venture Combined Statements of Operations do not include any operations or our share of net income or excess investment amortization related to our investments in Klépierre, our other platform investments and our previously held equity investment in TRG prior to the October 31, 2025 transaction. Amounts included in Footnote D below exclude our share of related activity for our investments in Klépierre, our other platform investments and our previously held equity investment in TRG prior to the October 31, 2025 transaction. For further information on Klépierre, reference should be made to financial information in Klépierre’s public filings and additional discussion and analysis in our Form 10-K. (C) This report contains measures of financial or operating performance that are not specifically defined by GAAP, including FFO, FFO per share, Real Estate FFO and Real Estate FFO per share. FFO is a performance measure that is standard in the REIT business. We believe FFO provides investors with additional information concerning our operating performance and a basis to compare our performance with those of other REITs. We also use these measures internally to monitor the operating performance of our portfolio. Our computation of these non-GAAP measures may not be the same as similar measures reported by other REITs. We determine FFO based upon the definition set forth by the National Association of Real Estate Investment Trusts (“NAREIT”) Funds From Operations White Paper –2018 Restatement. Our main business includes acquiring, owning, operating, developing, and redeveloping real estate in conjunction with the rental of retail real estate. Gains and losses of assets incidental to our main business are included in FFO. We determine FFO to be our share of consolidated net income computed in accordance with GAAP, excluding real estate related depreciation and amortization, excluding gains and losses from the sale, disposal or property insurance recoveries of, or any impairment related to, depreciable retail operating properties, plus the allocable portion of FFO of unconsolidated joint ventures based upon economic ownership interest, and all determined on a consistent basis in accordance with GAAP. However, you should understand that FFO does not represent cash flow from operations as defined by GAAP, should not be considered as an alternative to net income determined in accordance with GAAP as a measure of operating performance, and is not an alternative to cash flows as a measure of liquidity. (D) Includes our share of: – Gain on land sales of $0.0 million and $18.5 million for the three months ended September 30, 2026 and 2025, respectively, and $1.8 million and $19.7 million for the nine months ended September 30, 2026 and 2025, respectively. – Straight-line adjustments increased income by $20.8 million and $16.0 million for the three months ended September 30, 2026 and 2025, respectively, and $45.7 million and $21.9 million for the nine months ended September 30, 2026 and 2025, respectively. – Amortization of fair market value of leases increased income by $2.4 million and $0.3 million for the three months ended September 30, 2026 and 2025, respectively, and $3.0 million and $0.9 million for the nine months ended September 30, 2026 and 2025, respectively.

NON-GAAP PRO-RATA FINANCIAL INFORMATION The following pro-rata financial information is not, and is not intended to be, a presentation in accordance with GAAP. The non-GAAP pro-rata financial information aggregates our proportionate economic ownership of each asset in our property portfolio that we do not wholly own. The amounts in the column labeled “Our Share of Joint Ventures” were derived on a property-by-property or entity-by-entity basis by applying to each line item the ownership percentage interest used to arrive at our share of the net operations for the period consistent with the application of the equity method of accounting to each of our unconsolidated joint ventures. A similar calculation was performed for the amounts in the column labeled “Noncontrolling Interests,” which represents the share of consolidated assets and net income or loss attributable to any noncontrolling interest. We do not control the unconsolidated joint ventures and the presentations of the assets and liabilities and revenues and expenses do not represent our legal claim to such items. The operating agreements of the unconsolidated joint ventures generally provide that partners may receive cash distributions (1) to the extent there is available cash from operations, (2) upon a capital event, such as a refinancing or sale or (3) upon liquidation of the venture. The amount of cash each partner receives is based upon specific provisions of each operating agreement and varies depending on factors including the amount of capital contributed by each partner and whether any contributions are entitled to priority distributions. Upon liquidation of the joint venture and after all liabilities, priority distributions and initial equity contributions have been repaid, the partners generally would be entitled to any residual cash remaining based on their respective legal ownership percentages. We provide pro-rata financial information because we believe it assists investors and analysts in estimating our economic interest in our unconsolidated joint ventures when read in conjunction with the Company’s reported results under GAAP. The presentation of pro-rata financial information has limitations as an analytical tool. Some of these limitations include: • The amounts shown on the individual line items were derived by applying our overall economic ownership interest percentage determined when applying the equity method of accounting and do not necessarily represent our legal claim to the assets and liabilities, or the revenues and expenses; and • Other companies in our industry may calculate their pro-rata interest differently than we do, limiting the usefulness as a comparative measure. Because of these limitations, the pro-rata financial information should not be considered in isolation or as a substitute for our financial statements as reported under GAAP. We compensate for these limitations by relying primarily on our GAAP results and using the pro-rata financial information only supplementally.

(1) Represents our venture partners’ share of operations from consolidated properties. (2) Our Total Share of income from unconsolidated entities excludes our share of net results related to our investment in Klépierre, RGG, Catalyst, Jamestown, and our previously held equity investment in TRG up to the October 31, 2025 transaction. (3) Represents limited partners’ interest in the Operating Partnership.

Materials and Website Supplemental information on our third quarter 2026
performance is available at investors.simon.com. This information has also been
furnished to the SEC in a current report on Form 8-K. We routinely post
important information online on our investor relations website,
investors.simon.com. We use this website, press releases, SEC filings, quarterly
conference calls, presentations and webcasts to disclose material, non-public
information in accordance with Regulation FD. We encourage members of the
investment community to monitor these distribution channels for material
disclosures. Any information accessed through our website is not incorporated by
reference into, and is not a part of, this document. Non-GAAP Financial Measures
This press release includes FFO, FFO per share, Real Estate FFO, Real Estate FFO
per share and domestic and portfolio NOI growth which are financial performance
measures not defined by generally accepted accounting principles in the United
States (“GAAP”). Real Estate FFO is FFO of the operating partnership less other
platform investments and loss (gain) due to disposal, exchange, or revaluation
of equity interests, in each case, net of tax; and unrealized losses (gains) in
fair value of publicly traded equity instruments and derivative instrument, net.
Reconciliations of these non-GAAP financial measures to the most directly
comparable GAAP measures are included in Simon’s supplemental information for
the quarter. FFO and NOI growth are financial performance measures widely used
in the REIT industry. Our definitions of these non-GAAP measures may not be the
same as similar measures reported by other REITs.

EARNINGS RELEASE Forward-Looking Statements Certain statements made in this
press release may be deemed “forward-looking statements” within the meaning of
the Private Securities Litigation Reform Act of 1995. Although Simon believes
the expectations reflected in any forward-looking statements are based on
reasonable assumptions, Simon can give no assurance that its expectations will
be attained, and it is possible that Simon’s actual results may differ
materially from those indicated by these forward-looking statements due to a
variety of risks, uncertainties and other factors. Such factors include, but are
not limited to: the intensely competitive market environment in the retail real
estate industry and the retail industry, including e-commerce, as well as
evolving consumer preferences and purchasing habits; the inability to renew
leases and relet vacant space at existing properties on favorable terms; the
inability to collect rent due to the bankruptcy or insolvency of tenants or
otherwise; the potential loss of anchor stores or major tenants; an increase in
vacant space at our properties; the loss of key management personnel; changes in
economic and market conditions that may adversely affect the general retail
environment, including but not limited to those caused by inflation, the impact
of tariffs and global trade disruptions on us to the extent impacting our
tenants, recessionary pressures, wars, escalating geopolitical tensions as a
result of the war in Ukraine and the conflicts in the Middle East, and supply
chain disruptions; the potential for violence, civil unrest, criminal activity
or terrorist activities, or inappropriate or unacceptable behavior by visitors,
at our properties; the availability of comprehensive insurance coverage;
security breaches that could compromise our information technology or
infrastructure; risks associated with artificial intelligence, including
generative artificial intelligence technologies, and the evolving regulatory
environment applicable to those technologies; changes in market rates of
interest; our international activities subjecting us to risks that are different
from or greater than those associated with our domestic operations, including
changes in foreign exchange rates; the impact of our substantial indebtedness on
our future operations, including covenants in the governing agreements that
impose restrictions on us that may affect our ability to operate freely; any
disruption in the financial markets that may adversely affect our ability to
access capital for growth and satisfy our ongoing debt service requirements; any
change in our credit rating; our continued ability to maintain our status as a
REIT; changes in tax laws or regulations that result in adverse tax
consequences; risks associated with the acquisition, development, redevelopment,
expansion, leasing and management of properties; the inability to lease newly
developed properties on favorable terms; risks relating to our joint venture
properties, including guarantees of certain joint venture indebtedness; the
effects of climate change; environmental liabilities; natural or other
disasters; uncertainties regarding the impact of pandemics, epidemics or public
health crises, and the associated governmental restrictions on our business,
financial condition, results of operations, cash flow and liquidity; and general
risks related to real estate investments, including the illiquidity of real
estate investments. Simon discusses these and other risks and uncertainties
under the heading “Risk Factors” in its annual and quarterly periodic reports
filed with the SEC. Simon may update that discussion in subsequent other
periodic reports, but except as required by law, Simon undertakes no duty or
obligation to update or revise these forward-looking statements, whether as a
result of new information, future developments, or otherwise. About Simon Simon

EARNINGS RELEASE Simon Property Group, Inc. Footnotes to Unaudited Financial
Information Notes: (A) Excess investment represents the unamortized difference
of our investment over equity in the underlying net assets of the related
partnerships and joint ventures shown therein. The Company generally amortizes
excess investment over the life of the related assets. (B) The Unaudited Joint
Venture Combined Statements of Operations do not include any operations or our
share of net income or excess investment amortization related to our investments
in Klépierre, our other platform investments and our previously held equity
investment in TRG prior to the October 31, 2025 transaction. Amounts included in
Footnote D below exclude our share of related activity for our investments in
Klépierre, our other platform investments and our previously held equity
investment in TRG prior to the October 31, 2025 transaction. For further
information on Klépierre, reference should be made to financial information in
Klépierre’s public filings and additional discussion and analysis in our Form
10-K. (C) This report contains measures of financial or operating performance
that are not specifically defined by GAAP, including FFO, FFO per share, Real
Estate FFO and Real Estate FFO per share. FFO is a performance measure that is
standard in the REIT business. We believe FFO provides investors with additional
information concerning our operating performance and a basis to compare our
performance with those of other REITs. We also use these measures internally to
monitor the operating performance of our portfolio. Our computation of these
non-GAAP measures may not be the same as similar measures reported by other
REITs. We determine FFO based upon the definition set forth by the National
Association of Real Estate Investment Trusts (“NAREIT”) Funds From Operations
White Paper –2018 Restatement. Our main business includes acquiring, owning,
operating, developing, and redeveloping real estate in conjunction with the
rental of retail real estate. Gains and losses of assets incidental to our main
business are included in FFO. We determine FFO to be our share of consolidated
net income computed in accordance with GAAP, excluding real estate related
depreciation and amortization, excluding gains and losses from the sale,
disposal or property insurance recoveries of, or any impairment related to,
depreciable retail operating properties, plus the allocable portion of FFO of
unconsolidated joint ventures based upon economic ownership interest, and all
determined on a consistent basis in accordance with GAAP. However, you should
understand that FFO does not represent cash flow from operations as defined by
GAAP, should not be considered as an alternative to net income determined in
accordance with GAAP as a measure of operating performance, and is not an
alternative to cash flows as a measure of liquidity. (D) Includes our share of:
– Gain on land sales of $0.0 million and $18.5 million for the three months
ended September 30, 2026 and 2025, respectively, and $1.8 million and $19.7
million for the nine months ended September 30, 2026 and 2025, respectively. –
Straight-line adjustments increased income by $20.8 million and $16.0 million
for the three months ended September 30, 2026 and 2025, respectively, and $45.7
million and $21.9 million for the nine months ended September 30, 2026 and 2025,
respectively. – Amortization of fair market value of leases increased income by
$2.4 million and $0.3 million for the three months ended September 30, 2026 and
2025, respectively, and $3.0 million and $0.9 million for the nine months ended
September 30, 2026 and 2025, respectively.

operational and balance sheet information as of September 30, 2026 for the
Company and the Operating Partnership. Certain statements made in this
Supplemental Package may be deemed “forward-looking statements” within the
meaning of the Private Securities Litigation Reform Act of 1995. Although we
believe the expectations reflected in any forward-looking statements are based
on reasonable assumptions, we can give no assurance that our expectations will
be attained, and it is possible that our actual results may differ materially
from those indicated by these forward-looking statements due to a variety of
risks, uncertainties and other factors. Such factors include, but are not
limited to: the intensely competitive market environment in the retail real
estate industry and the retail industry, including e-commerce, as well as
evolving consumer preferences and purchasing habits; the inability to renew
leases and relet vacant space at existing properties on favorable terms; the
inability to collect rent due to the bankruptcy or insolvency of tenants or
otherwise; the potential loss of anchor stores or major tenants; an increase in
vacant space at our properties; the loss of key management personnel; changes in
economic and market conditions that may adversely affect the general retail
environment, including but not limited to those caused by inflation, the impact
of tariffs and global trade disruptions on us to the extent impacting our
tenants, recessionary pressures, wars, escalating geopolitical tensions as a
result of the war in Ukraine and the conflicts in the Middle East, and supply
chain disruptions; the potential for violence, civil unrest, criminal activity
or terrorist activities, or inappropriate or unacceptable behavior by visitors,
at our properties; the availability of comprehensive insurance coverage;
security breaches that could compromise our information technology or
infrastructure; risks associated with artificial intelligence, including
generative artificial intelligence technologies, and the evolving regulatory
environment applicable to those technologies; changes in market rates of
interest; our international activities subjecting us to risks that are different
from or greater than those associated with our domestic operations, including
changes in foreign exchange rates; the impact of our substantial indebtedness on
our future operations, including covenants in the governing agreements that
impose restrictions on us that may affect our ability to operate freely; any
disruption in the financial markets that may adversely affect our ability to
access capital for growth and satisfy our ongoing debt service requirements; any
change in our credit rating; our continued ability to maintain our status as a
REIT; changes in tax laws or regulations that result in adverse tax
consequences; risks associated with the acquisition, development, redevelopment,
expansion, leasing and management of properties; the inability to lease newly
developed properties on favorable terms; risks relating to our joint venture
properties, including guarantees of certain joint venture indebtedness; the
effects of climate change; environmental liabilities; natural or other
disasters; uncertainties regarding the impact of pandemics, epidemics or public
health crises, and the associated governmental restrictions on our business,
financial condition, results of operations, cash flow and liquidity; and general
risks related to real estate investments, including the illiquidity of real
estate investments. We discuss these and other risks and uncertainties under the
heading “Risk Factors” in our annual and quarterly periodic reports filed with
the SEC. We may update that discussion in subsequent other periodic reports,
but, except as required by law, we undertake no duty or obligation to update or
revise these forward-looking statements, whether as a result of new information,
future developments, or otherwise. Any questions, comments or suggestions
regarding this Supplemental Information should be directed to Tom Ward, Senior
Vice President of Investor Relations (tom.ward@simon.com or 317.685.7330).

This report contains measures of financial or operating performance that are not
specifically defined by generally accepted accounting principles (GAAP) in the
United States, including FFO, FFO per share, Real Estate FFO, Real Estate FFO
per share, funds available for distribution, net operating income (NOI),
domestic property NOI and portfolio NOI. FFO and NOI are performance measures
that are standard in the REIT business. We believe FFO, Real Estate FFO and NOI
provide investors with additional information concerning our operating
performance and a basis to compare our performance with the performance of other
REITs. We also use these measures internally to monitor the operating
performance of our portfolio. Our computation of these non-GAAP measures may not
be the same as similar measures reported by other REITs. The non-GAAP financial
measures used in this report should not be considered as alternatives to net
income as a measure of our operating performance or to cash flows computed in
accordance with GAAP as a measure of liquidity nor are they indicative of cash
flows from operating and financial activities. Reconciliations of other non-GAAP
measures used in this report to the most-directly comparable GAAP measure are
included in the tables on Reconciliations of Non-GAAP Financial Measures and in
the Earnings Release for the latest period.

outlots in the calculation. (2) Base Minimum Rent PSF is the average base
minimum rent charge in effect for the reporting period for all tenants that
would qualify to be included in Ending Occupancy as defined above. (3) For the

NON-GAAP PRO-RATA FINANCIAL INFORMATION The following pro-rata financial
information is not, and is not intended to be, a presentation in accordance with
GAAP. The non-GAAP pro-rata financial information aggregates our proportionate
economic ownership of each asset in our property portfolio that we do not wholly
own. The amounts in the column labeled “Our Share of Joint Ventures” were
derived on a property-by-property or entity-by-entity basis by applying to each
line item the ownership percentage interest used to arrive at our share of the
net operations for the period consistent with the application of the equity
method of accounting to each of our unconsolidated joint ventures. A similar
calculation was performed for the amounts in the column labeled “Noncontrolling
Interests,” which represents the share of consolidated assets and net income or
loss attributable to any noncontrolling interest. We do not control the
unconsolidated joint ventures and the presentations of the assets and
liabilities and revenues and expenses do not represent our legal claim to such
items. The operating agreements of the unconsolidated joint ventures generally
provide that partners may receive cash distributions (1) to the extent there is
available cash from operations, (2) upon a capital event, such as a refinancing
or sale or (3) upon liquidation of the venture. The amount of cash each partner
receives is based upon specific provisions of each operating agreement and
varies depending on factors including the amount of capital contributed by each
partner and whether any contributions are entitled to priority distributions.
Upon liquidation of the joint venture and after all liabilities, priority
distributions and initial equity contributions have been repaid, the partners
generally would be entitled to any residual cash remaining based on their
respective legal ownership percentages. We provide pro-rata financial
information because we believe it assists investors and analysts in estimating
our economic interest in our unconsolidated joint ventures when read in
conjunction with the Company’s reported results under GAAP. The presentation of
pro-rata financial information has limitations as an analytical tool. Some of
these limitations include: • The amounts shown on the individual line items were
derived by applying our overall economic ownership interest percentage
determined when applying the equity method of accounting and do not necessarily
represent our legal claim to the assets and liabilities, or the revenues and
expenses; and • Other companies in our industry may calculate their pro-rata
interest differently than we do, limiting the usefulness as a comparative
measure. Because of these limitations, the pro-rata financial information should
not be considered in isolation or as a substitute for our financial statements
as reported under GAAP. We compensate for these limitations by relying primarily
on our GAAP results and using the pro-rata financial information only
supplementally.
