ITEM 8.01 Other Events

At the Meeting, the Company’s shareholders approved a proposal to redomesticate, by conversion, the Company from a corporation organized under the laws of the State of Delaware (the “Delaware Corporation”) to a corporation organized under the laws of the State of Indiana (the “Indiana Corporation”) by means of a plan of conversion (the “Plan of Conversion”, and such redomestication, the “Redomestication”), as described in the Company’s Definitive Proxy Statement for the Meeting (as supplemented by certain additional materials filed with the SEC on May 5, 2025, the “Proxy Statement”). Additionally, the limited partners of the Company’s operating partnership, Simon Property Group, L.P. (the “Operating Partnership”), separately approved a redomestication by conversion from a limited partnership formed under the laws of the State of Delaware (the “Delaware OP”) to a limited partnership formed under the laws of the State of Indiana (the “Indiana OP”) by means of a plan of conversion (the “OP Plan of Conversion”, and such redomestication, the “OP Redomestication”).

On May 14, 2025, the Company filed (i) a certificate of conversion with the Secretary of State of the State of Delaware and (ii) articles of domestication with the Secretary of State of the State of Indiana, pursuant to which the Redomestication became effective on May 15, 2025, at 12:01 a.m. Eastern Time (the “Effective Time”). At the Effective Time:

Additionally, on May 14, 2025, the Operating Partnership filed (i) a certificate of conversion with the Secretary of State of the State of Delaware and (ii) articles of domestication with the Secretary of State of the State of Indiana, pursuant to which the OP Redomestication became effective on May 15, 2025, at 12:02 a.m. Eastern Time (the “OP Effective Time”). At the OP Effective Time:

Neither the Redomestication nor the OP Redomestication resulted in any change in the headquarters, business, jobs, management, properties, location of any of our offices or facilities, number of employees, obligations, assets, liabilities, or net worth (other than as a result of the costs related to the Redomestication and OP Redomestication). Neither the Redomestication nor the OP Redomestication materially affected any of the Company’s or the Operating Partnership’s material contracts with any third parties, and the Company’s or the Operating Partnership’s, as applicable, rights and obligations under those material contractual arrangements continue to be the rights and obligations of the Company and the Operating Partnership, as applicable, after the Redomestication and OP Redomestication.

At the Effective Time, (i) each outstanding share of common stock, par value $0.0001 per share, of the Delaware Corporation (the “Delaware Common Stock”) automatically converted into one outstanding share of common stock, par value $0.0001 per share, of the Indiana Corporation (the “Indiana Common Stock”), (ii) each outstanding share of Class B common stock, par value $0.0001 per share, of the Delaware Corporation automatically converted into one outstanding share of Class B common stock, par value $0.0001 per share, of the Indiana Corporation, and (iii) each outstanding share of 8 3/8% Series J Cumulative Redeemable Preferred Stock, par value $0.0001 per share, of the Delaware Corporation automatically converted into one outstanding share of 8 3/8% Series J Cumulative Redeemable Preferred Stock, par value $0.0001 per share, of the Indiana Corporation (the “Indiana Series J Preferred Stock”). Shareholders do not have to exchange their existing stock certificates for new stock certificates. At the Effective Time, each outstanding restricted stock unit or right to acquire shares of Delaware Common Stock will continue in existence and automatically become a restricted stock unit or right to acquire an equal number of shares of Indiana Common Stock under the same terms and conditions. The Indiana Common Stock continues to be traded on the New York Stock Exchange (the “NYSE”) under the symbol “SPG”, and the Indiana Series J Preferred Stock continues to be traded on the NYSE under the symbol “SPGJ”.

At the OP Effective Time, (i) each outstanding unit of limited partnership interest of the Delaware OP automatically converted into one outstanding unit of limited partnership interest of the Indiana OP, and (ii) each outstanding long-term incentive plan interest of the Delaware OP automatically converted into one outstanding long-term incentive plan interest of the Indiana OP.

Certain rights of the Company’s shareholders were changed as a result of the Redomestication. A more detailed description of the Plan of Conversion, Indiana Charter, Indiana Bylaws, and the effects of the Redomestication is set forth in the Proxy Statement under “Proposal 4: Approval of the Redomestication of the Company to the State of Indiana by Conversion”, which description is incorporated herein by reference.

Copies of the (i) Plan of Conversion, (ii) OP Plan of Conversion, (iii) Indiana Charter, (iv) Indiana Bylaws, (v) Indiana Certificate of Limited Partnership, and (vi) Ninth Amended and Restated Partnership Agreement are filed as Exhibits 2.1, 2.2, 3.1, 3.2, 3.3, and 3.4, respectively, to this Current Report on Form 8-K and are incorporated herein by reference.
