ITEM 8.01 Other Events.

On August 12, 2025, the Operating Partnership entered into an underwriting agreement (the “Underwriting Agreement”) with BBVA Securities Inc., J.P. Morgan Securities LLC, TD Securities (USA) LLC and Wells Fargo Securities, LLC, as representatives of the underwriters named therein (collectively, the “Underwriters”), in connection with the public offering of $700,000,000 aggregate principal amount of the Operating Partnership’s 4.375% notes due 2030 (the “2030 Notes”) and $800,000,000 aggregate principal amount of the Operating Partnership’s 5.125% notes due 2035 (the “2035 Notes” and, together with the 2030 Notes, the “Notes”). The Underwriting Agreement contains representations and warranties and covenants that are customary for transactions of this type. In addition, the Operating Partnership has agreed to indemnify the Underwriters against certain liabilities on customary terms. The Underwriters have performed, and expect in the future to perform, investment banking and advisory services for which they have received, and may continue to receive, customary fees and expenses, and affiliates of the Underwriters have performed, and expect in the future to perform, commercial lending services, for the Operating Partnership and its affiliates from time to time.

The Notes were issued on August 19, 2025 pursuant to the Operating Partnership’s Indenture (the “Base Indenture”), dated as of November 26, 1996, between the Operating Partnership and The Bank of New York Mellon Trust Company, N.A. (as successor to The Chase Manhattan Bank), as trustee (the “Trustee”), as amended and supplemented by the Forty-Seventh Supplemental Indenture, dated as of August 19, 2025 (the “Forty-Seventh Supplemental Indenture” and, together with the Base Indenture, the “Indenture”), between the Operating Partnership and the Trustee, setting forth the terms of the Notes.

The 2030 Notes bear interest at a rate of 4.375% per annum and mature on October 1, 2030. The 2035 Notes bear interest at a rate of 5.125% per annum and mature on October 1, 2035. Interest on the 2030 Notes and the 2035 Notes is payable semi-annually in arrears on April 1 and October 1, beginning April 1, 2026 (each, an “Interest Payment Date”). Interest will be paid to holders of record of such Notes registered at the close of business on the fifteenth calendar day preceding the related Interest Payment Date.

The Operating Partnership may redeem the Notes of any series at its option at any time, in whole or from time to time in part, on not less than 10 and not more than 60 days’ prior written notice mailed to the holders of the Notes to be redeemed. The Notes of each series will be redeemable at a price equal to the principal amount of such Notes being redeemed, plus unpaid interest accrued to, but not including, the date of redemption and a “make-whole” premium calculated under the Forty-Seventh Supplemental Indenture with respect to the 2030 Notes and the 2035 Notes (unless the 2030 Notes are redeemed on or after September 1, 2030, or the 2035 Notes are redeemed on or after July 1, 2035, in which case no “make-whole” premium will be payable).

The Notes will be subject to customary events of default, including, among other things, nonpayment, failure to comply with the other agreements in the Indenture for a period of 90 days after notice, and certain events of bankruptcy, insolvency and reorganization.

The foregoing descriptions are qualified in their entirety by the Underwriting Agreement and the Forty-Seventh Supplemental Indenture (including the forms of notes attached thereto) which are filed as Exhibits 1.1 and 4.1 to this Current Report on Form 8-K, respectively, and are incorporated by reference herein. The Form of 2030 Notes is filed as Exhibit 4.2 and the Form of 2035 Notes is filed as Exhibit 4.3 to this Current Report on Form 8-K, and each is incorporated by reference herein. A copy of the Underwriting Agreement is attached hereto as Exhibit 1.1 and a copy of the Forty-Seventh Supplemental Indenture is attached hereto as Exhibit 4.1.
