This Amendment No. 22 relates to the common stock, par value $0.01 per share (“Common Stock”), of GGP Inc. (formerly General Growth Properties, Inc.), a Delaware corporation (the “Company”). Capitalized terms used but not defined in this Amendment No. 22 shall have the meanings ascribed to them in the Schedule 13D.

Item 2. Identity and Background.

Item 2 of the Schedule 13D is hereby amended to include the following:

(a) BPR Holding REIT I LLC (“BPR Holding”), a Delaware limited liability company, of which New BPI Subco is the sole managing member.

(b), (c) The principal business of BPR Holding is to serve as a holding company. The principal business address of BPR Holding is Brookfield Place, 250 Vesey Street, New York, NY 10281-1023.

Schedule LXXXV to this Amendment No. 22 sets forth the principal business address and principal occupation or employment of each executive officer of BPR Holding. Such persons shall be included in the definition of Scheduled Persons.

(d), (e) During the last five years, none of the Scheduled Persons of BPR Holding (i) has been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors) or (ii) has been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree, or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws.

(f) Schedule LXXXV to this Amendment No. 22 sets forth the citizenships of each of the Scheduled Persons of BPR Holding.

Item 3. Source and Amount of Funds or Other Consideration.

Item 3 of the Schedule 13D is hereby amended to incorporate by reference Item 4 of this Amendment No. 22.

Item 4. Purpose of the Transaction.

Item 4 of the Schedule 13D is hereby amended to include the following:

In connection with an internal reorganization of certain of Parent’s affiliates, (i) the sole member of each of the following Voting Parties was replaced with BPR Holding: Retail Mall (as hereinafter defined), New GGP Subco, BWP and New GGP Warrants (as hereinafter defined), and (ii) BPR Holding became a non-managing member of BRH Warrants. Each of the aforementioned Voting Parties continues to be an indirect wholly-owned subsidiary of Parent.

On July 26, 2018, the Company held the special meeting of the holders of Common Stock of the Company, at which the Company’s holders of record of Common Stock as of June 22, 2018 voted to approve the following matters: (i) the adoption of the Merger Agreement; (ii) the approval of the Charter Amendment; (iii) the approval of the Bylaws Amendment; and (iv) the approval of compensation that may become payable to the Company’s named executive officers in connection with the Transactions. Therefore, on July 27, 2018, the Company filed the Series B Designations with the Secretary of State of the State of Delaware, which authorized the issuance of the Series B Preferred Stock. Following the filing of the Series B Designations, the Class B Exchange occurred, in which the Voting Parties exchanged the 323,641,838 shares of Common Stock collectively owned by them, for an equal number of shares of Series B Preferred Stock, on the terms and subject to the conditions set forth in the Class B Exchange Agreement (which was previously filed as Exhibit 99.2 to Amendment No. 21).

Pursuant to the Series B Designations, in the event that the Merger Agreement is terminated in accordance with its terms prior to the time that at which the Charter Amendment is filed with and accepted by the Secretary of State of the State of Delaware, then each share of Series B Preferred Stock will be automatically, without any action by the Company or any holder, converted into one fully paid and non-assessable share of Common Stock, without the payment of any accrued and unpaid dividends.

Item 5. Interest in Securities of the Issuer.

Item 5(a)-(c) of the Schedule 13D is hereby amended in its entirety as follows:

(a)-(b) All calculations of percentages of beneficial ownership in this Item 5 and elsewhere in this Schedule 13D are based on the 958,391,980 shares of Common Stock reported by the Company as outstanding, as of May 3, 2018, in its quarterly report on Form 10-Q filed with the SEC on May 7, 2018.
