This amendment No. 18 (“Amendment No. 18”) to Schedule 13D relates to the Schedule 13D filed on December 4, 2019 (as amended and supplemented prior to the filing of this Amendment No. 18, the “Schedule 13D”) by (i) Pershing Square Capital Management, L.P., a Delaware limited partnership (“Pershing Square”), (ii) PS Management GP, LLC, a Delaware limited liability company (“PS Management”), and (iii) William A. Ackman, a citizen of the United States (together with Pershing Square and PS Management, the “Reporting Persons”), relating to the Common Stock of Howard Hughes Holdings Inc., a Delaware corporation.

Capitalized terms used but not defined in this Amendment No. 18 shall have the meanings set forth in the Schedule 13D.

Except as specifically amended by this Amendment No. 18, the Schedule 13D is unchanged.

Item 1. Security and Issuer

Item 1 of the Schedule 13D is hereby replaced with the following information:

“This statement on Schedule 13D relates to the common stock, par value $0.01 per share (the “Common Stock”), of Howard Hughes Holdings Inc., a Delaware corporation (the “Issuer”). The principal executive offices of the Issuer are located at 9950 Woodloch Forest Drive, Suite 1100, The Woodlands, TX, 77380.

The Reporting Persons beneficially own 18,852,064 shares of Common Stock (the “Subject Shares”).

The Subject Shares represent approximately 37.5% of the outstanding shares of Common Stock, based on 50,259,345 shares of Common Stock outstanding as of May 1, 2024, as reported in the Issuer’s Form 10-Q filed on May 8, 2024 for the quarter ended March 31, 2024.”

Item 4. Purpose of Transaction

Item 4 of the Schedule 13D is hereby amended and supplemented by adding the following information:

“On October 5, 2023, the Issuer announced its intention to separate into two independent publicly traded companies. Seaport Entertainment Group Inc. (“Seaport Entertainment”), which is expected to be separated from the Issuer, will be comprised of the Issuer’s entertainment-related assets in New York City and Las Vegas, including the Seaport in Lower Manhattan, a 25% minority interest in Jean-Georges Restaurants as well as other partnerships, the Las Vegas Aviators Triple-A Minor League Baseball team and Las Vegas Ballpark, an interest in and to 80% of the air rights above the Fashion Show mall in Las Vegas and certain other assets and liabilities that the Issuer is expected to contribute to Seaport Entertainment prior to the separation.

On May 23, 2024, Seaport Entertainment filed with the Securities and Exchange Commission (the “SEC”) a registration statement on Form 10 for the registration of Seaport Entertainment common stock for purposes of listing that common stock on the New York Stock Exchange in connection with the separation of Seaport Entertainment from the Issuer.

Also on May 23, 2024, Seaport Entertainment filed with the SEC a registration statement on Form S-1 in connection with a proposed $175 million rights offering to Seaport Entertainment stockholders, which is expected to be commenced following the separation and distribution. In the Rights Offering, Seaport Entertainment would distribute, at no charge, to holders of its common stock, transferable subscription rights, which will entitle holders to purchase shares of Seaport Entertainment common stock.

In connection with the Rights Offering, the Reporting Persons are in serious discussions with Seaport Entertainment regarding a potential backstop agreement that investment funds affiliated with the Reporting Persons would enter into prior to the distribution. Pursuant to that agreement, if finalized, those funds would agree, severally and not jointly, to (i) exercise their pro rata subscription rights with respect to the Rights Offering and (ii) purchase on a pro rata basis any shares that are not purchased in the Rights Offering upon the expiration thereof at the Rights Offering price, at a purchase price of up to $175 million in the aggregate. To the extent that Seaport Entertainment stockholders fail to participate in the Rights Offering, the backstop agreement could result in investment funds affiliated with the Reporting Persons owning in aggregate a higher percentage of Seaport Entertainment’s common stock.

The Reporting Persons do not intend to disclose developments with respect to the foregoing, except as may be required by applicable law.”
