### Footnotes:

(1) Includes 5,059 restricted stock units ("RSUs") granted to the Reporting Person on August 7, 2024 pursuant to the Issuer's 2024 Equity Incentive Plan (the "Plan"). Each RSU represents a contingent right to receive one share of the Issuer's common stock. These 5,059 RSUs will vest in two substantially equal installments on August 1, 2026 and August 1, 2027, subject to the Reporting Person's continued service with the Issuer or its subsidiaries through the vesting dates.

(2) On July 31, 2024 (the "Distribution Date"), Howard Hughes Holdings Inc. ("HHH") completed a pro rata spin-off distribution (the "Distribution") of all of its shares of common stock of the Issuer to the holders of record of HHH common stock as of the close of business on July 29, 2024 (the "Record Date"). In connection with the Distribution, pursuant to the terms of the Employee Matters Agreement, dated as of July 31, 2024, by and between HHH and the Issuer (the "EMA"), all outstanding equity awards with respect to HHH common stock held by the Reporting Person were equitably adjusted and converted into equity awards with respect to the Issuer's common stock, with such equitable adjustments determined based on (i) the volume weighted average per-share price of HHH common stock for the three trading-day period ending on the Distribution Date and (ii) the volume weighted average per-share price of the Issuer's common stock for the thirty trading-day period following the Distribution Date.

(3) Includes 4,638 shares of restricted stock of the Issuer that were granted to the Reporting Person upon the conversion of restricted stock of HHH held by the Reporting Person as of July 31, 2024 in connection with the Distribution, in accordance with the terms of the EMA. The shares of restricted stock of the Issuer were granted pursuant to the Plan in a manner intended to preserve the aggregate intrinsic value of the awards, on generally the same terms and conditions (including vesting schedules) as applicable to the corresponding shares of restricted stock of HHH. The shares of restricted stock of the Issuer will vest in two substantially equal installments on March 1, 2026 and March 1, 2027, subject to the Reporting Person's continued service with the Issuer or its subsidiaries through the vesting dates.

(4) Includes 4,538 RSUs granted to the Reporting Person on March 7, 2025 pursuant to the Plan. Each RSU represents a contingent right to receive one share of the Issuer's common stock. These 4,538 RSUs will vest in three substantially equal annual installments beginning on March 7, 2026, subject to the Reporting Person's continued service with the Issuer or its subsidiaries through the vesting dates.
