SIMON PROPERTY GROUP, INC.

Shareholders of Simon Property Group, Inc.

Simon Property Group, Inc. is a widely held NYSE-listed company, so no complete shareholder register is published. The authoritative disclosure is the beneficial-ownership table in the definitive proxy statement filed on 1 April 2026, which lists every person or group known to the company to beneficially own more than 5% of any class of its voting securities as at 16 March 2026.

The MSA Group figure is not an ordinary free-float holding: it comprises 2,210,610 outstanding common shares, 26,941,191 common shares issuable on exchange of operating-partnership units, and all 8,000 outstanding shares of Class B common stock, and its percentage assumes exchange of units by that holder alone. Class B common stock is the class that carries the family position — it is held under a voting trust and entitles its holders to elect up to four directors. The proxy records that Melvin Simon & Associates, Inc. is owned 30.94% by trusts for the benefit of Herbert Simon, 3.04% by a trust for the benefit of David Simon, and by certain other shareholders.

The Vanguard Group, Inc. reported nil beneficial ownership as at 13 March 2026, its Schedule 13G/A attributing the change to an internal realignment on 12 January 2026 after which certain subsidiaries and business divisions report on a disaggregated basis. Its previous Schedule 13G/A of 13 February 2024 had reported 45,707,505 shares. As at 31 January 2026 there were 324,945,274 common shares and 8,000 Class B shares outstanding, with 957 holders of record of the common stock.

Ultimate beneficial ownership

No ultimate beneficial owner can be identified from the filings. No holder disclosed in the 2026 proxy statement reaches a controlling position, and the largest disclosed holdings — BlackRock and State Street — are institutional asset managers reporting on behalf of managed funds and accounts rather than owners in their own right. The MSA Group holding at 8.29% is the only disclosed position that carries board-appointment rights, through the 8,000 Class B shares, but it is below any conventional beneficial-ownership threshold and is held across a company, several trusts and voting trusts rather than by one person. No further ownership chain that would allow an effective percentage to be calculated is published.

Data availability

Major shareholders only. United States disclosure captures reportable positions above 5% under Sections 13(d) and 13(g) of the Securities Exchange Act of 1934 together with the annual proxy table; there is no public register of all shareholders, and the absence of a holder from these filings is not evidence that the holding does not exist.

The 20 shareholder rows stored on this profile do not reconcile with the filings and have not been used. Their percentages sum to 99.99%, which makes each one that row’s share of the 20-row sample rather than of the company: measured against the 324,945,274 shares in issue, the stored quantities give Vanguard Group Inc 14.37% (stored as 21.60%), BlackRock 11.56% (stored as 17.39%) and State Street Corporation 6.70% (stored as 10.07%). The rows also double-count, listing “Vanguard Group Inc” alongside five individual Vanguard funds whose holdings sit inside it; the Vanguard Group Inc row is stale as to the entity as well as the figure, for the reason set out above; and the MSA Group, the Simon family position and the Class B common stock are absent from the stored data altogether.

Directors and officers of Simon Property Group, Inc.

Thirteen directors were elected at the annual meeting held on 13 May 2026. Eleven were elected by the holders of voting shares and all eleven are independent under the New York Stock Exchange listing standards: Glyn F. Aeppel (director since 2016), Martin J. Cicco (2026), Larry C. Glasscock (2010), Nina P. Jones (2024), Reuben S. Leibowitz (2005), Randall J. Lewis (2023), Gary M. Rodkin (2015), Peggy Fang Roe (2021), Stefan M. Selig (2017), Daniel C. Smith, Ph.D. (2009) and Marta R. Stewart (2018). Two further directors, Eli Simon and Richard S. Sokolov (Vice Chairman, director since 1996), were elected by the trustee of the voting trust holding the Class B common stock and are not independent. A third Class B seat was vacant at the date of the proxy statement.

The executive officers named in the Form 10-K filed on 25 February 2026 were David Simon, Eli Simon, John Rulli (Chief Administrative Officer), Steven E. Fivel (General Counsel and Secretary), Brian J. McDade (Executive Vice President and Chief Financial Officer), Adam J. Reuille (Senior Vice President and Chief Accounting Officer), Donald G. Frey (Treasurer and Executive Vice President) and Kevin M. Kelly (Assistant General Counsel and Assistant Secretary). That list has since changed, as set out below.

Recent officer changes

• Death of the Chairman, Chief Executive Officer and President. David Simon, who had chaired the board since 2007, served as chief executive since 1995 and as president since 2019, and was one of the three Class B directors, died on 22 March 2026. The company announced it on 23 March 2026. The voting trustee had not exercised its right to fill the resulting Class B vacancy as at 1 April 2026.
• New chief executive and non-executive chairman, effective 23 March 2026. The board appointed Eli Simon as Chief Executive Officer and President; he continues as Chief Operating Officer, a role he has held since 2025, and as a director. Larry C. Glasscock, an independent director, was appointed Non-Executive Chairman of the Board on the same date and continues on the Audit and Governance and Nominating Committees.
• New independent director, effective 5 February 2026. Martin J. Cicco, formerly Head of Real Estate Advisory at Evercore and Global Head of Real Estate Investment Banking at Merrill Lynch, joined the board and stood for election for the first time in May 2026.

Two earlier departures are recorded in the same filings: Herbert Simon retired from the board effective 4 February 2025 and Allan Hubbard retired effective 14 May 2025.

Data availability

Full for current officers, partial for historical detail. U.S. securities filings give the board, the executive officers, their roles, ages and the year each director joined, but they do not publish individual appointment or resignation dates for executive officers, and no U.S. federal filing discloses a director’s or officer’s nationality — nationality is therefore not disclosed for every person named here and must not be inferred from the Indianapolis business address. Indiana’s state business register is the registry of record for the entity but does not publish a full officer list.

The 30 officer rows stored on this profile are unreliable and were not used. Every row is marked ACTIVE, only one carries an appointment date, and David Simon is still shown as an active Chairman, CEO and President six months after his death. Several people appear twice, once under a state-filing role such as “Governor” and once under an executive title, and four job titles are truncated to “Dire”, “Secr”, “Pres” and “Assi”. Two rows — “C T Corporation System” and a corrupted “C Orporaion Sysem” — are registered agents rather than officers, and one locality field reads “33 INDIANAPOLIS”. Of the eleven independent directors, only Glyn F. Aeppel appears at all, with her role truncated.

Group structure of Simon Property Group, Inc.

Simon Property Group, Inc. has no parent. It is the top company of its group and is structured as an umbrella partnership REIT (UPREIT), and understanding that is the key to reading anything published about it, because two separate registrants share the name. Simon Property Group, Inc. is the listed REIT (NYSE: SPG, Commission File No. 001-14469). Simon Property Group, L.P. is a separate registrant — an Indiana limited partnership, Commission File No. 001-36110, CIK 0001022344 — which owns, directly or indirectly, substantially all of the group’s real estate and other assets, conducts substantially all of its business, and incurs all of its debt. The two file a single combined Form 10-K but remain distinct legal persons, and figures should be attributed to whichever entity the filing names.

Simon Property Group, Inc. is the sole general partner of the partnership and had an approximate 85.4% ownership interest in it at 31 December 2025, the remaining 14.6% being held by limited partners whose units are exchangeable for common shares or cash. The 10-K states that Simon Property Group, Inc. itself conducts no business other than acting as general partner and issuing equity, and has no material assets or liabilities other than its investment in the partnership.

Verified corporate relationships

Exhibit 21.1 to the 2025 Form 10-K names a further eight significant subsidiaries with their jurisdictions: Simon Property Group (Illinois), L.P. (Illinois); Simon Property Group (Texas), L.P. (Texas); M.S. Management Associates, Inc. (Delaware); Simon Property Group Administrative Services Partnership, L.P. (Delaware); Kravco Simon Investments, L.P. (Pennsylvania); Premium Outlet Partners, L.P. (Delaware); SPG Mayflower, LLC (Delaware); The Simon Realty Group, LLC (Delaware); and Simon Services, Inc. (Delaware). The exhibit states that it omits subsidiaries that were not, in the aggregate, significant subsidiaries at 31 December 2025, so it is not a complete list of the group.

Recent structural changes

• 31 October 2025 — acquisition of the remaining interest in The Taubman Realty Group, LLC. Simon had held an 88% non-controlling interest in TRG from 2020; on 31 October 2025 it acquired the outstanding 12%, issuing 4,980,693 operating-partnership units as part of the consideration and recognising a non-cash gain of $2.9 billion on remeasuring its previously held interest. Eleven former TRG properties are now accounted for as equity-method investments.
• 15 May 2025 — redomestication of both entities from Delaware to Indiana. Certificates of conversion were filed in Delaware and articles of domestication in Indiana on 14 May 2025; the company’s conversion took effect at 12:01 a.m. Eastern Time on 15 May 2025 and the operating partnership’s at 12:02 a.m. The company states that neither conversion changed its headquarters, business, properties, assets, liabilities or net worth.
• 21 July 2025 — incorporation of a UK subsidiary. Simon International Administrative Services Limited was incorporated in England and Wales with a registered office at 2 Sheraton Street, London W1F 8BH, and Simon Property Group, Inc. was entered on the same date as its person with significant control.

Data availability

Partial. United States disclosure requires only significant subsidiaries to be listed, and Exhibit 21.1 gives jurisdictions but no registration numbers and no ownership percentages, so most intra-group holdings cannot be quantified from public filings; the UK subsidiary is the exception, because the Companies House register of persons with significant control states a control band and a notification date.

The corporate-structure tree stored on this profile holds 172 nodes and is broadly consistent with the group, but it should be read with care. It carries no ownership percentage on any node. It lists Simon Property Group, L.P. twice as a direct child of the company, under two different identifiers, where there is one such partnership. It records The Simon Realty Group, LLC as a Michigan entity where Exhibit 21.1 states Delaware. The identifier on the company’s own node is an Indiana business identifier created on the 2025 redomestication, not a 1993-era record. The Taubman entities beneath “Silver Merger Sub 1, LLC” reflect the 2020 acquisition vehicle rather than any current holding chain.
