Pershing Square Inc.

Item 7.01 Regulation FD Disclosure. On June 4, 2026, Pershing Square Inc. (the “Company”) announced the availability of its financial supplement (the “Financial Supplement”) for the quarter ended March 31, 2026 and the month ended April 30, 2026 on the Company’s website (https://www.pershingsquareinc.com). The Financial Supplement includes the Company’s key operating metrics and fee-related earnings and distributable earnings, which are non-GAAP measures, for the periods presented. The Company uses various key operating metrics to assess and monitor the operating performance of its business, and fee-related earnings and distributable earnings to evaluate its business and assess performance and amounts available for distribution or dividends. See the Appendix in the Financial Supplement for the definitions of these metrics and reconciliations of the non-GAAP financial measures to the most comparable GAAP financial measure. The Company is providing key operating metrics for the month ended April 30, 2026 in addition to the quarter ended March 31, 2026 in the Financial Supplement because it believes that this incremental information would be useful to investors in understanding its performance through the completion of the combined initial public offering of the common shares of beneficial interest of Pershing Square USA, Ltd. and the distribution and public listing of the common stock of the Company on the NYSE, which closed on April 30, 2026. Going forward, the Company intends to disclose a financial supplement for completed fiscal periods only. The Financial Supplement is furnished as Exhibit 99.1 to this Report and is hereby incorporated by reference in this Item 7.01. As provided in General Instruction B.2 of Form 8-K, the information and exhibit contained in this Form 8-K shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, nor shall they be deemed to be incorporated by reference in any filing under the Securities Act of 1933, as amended, except as shall be expressly set forth by specific reference in such a filing.
