Unsecured Credit Facility
On July 25, 2025 and as amended on January 9, 2026, the Company entered into the Fifth Amended and Restated Revolving Credit and Term Loan Agreement (the “Unsecured Credit Facility”) with Wells Fargo Bank, National Association, as Administrative Agent; Wells Fargo Securities, LLC and JPMorgan Chase Bank, N.A. as Joint Book Runners; Wells Fargo Securities, LLC, JPMorgan Chase Bank, N.A., PNC Capital Markets LLC, U.S. Bank National Association, The Bank of Nova Scotia, and BofA Securities, Inc., as Joint Lead Arrangers; and the other lenders named therein. The New Credit Facility provides for (i) a $1.5 billion unsecured revolving credit facility (the “Revolver”) and (ii) five individual unsecured term loan tranches. At closing, $73.4 million of term loans were repaid. The OP is the borrower under the Unsecured Credit Facility (in such capacity, the “Borrower”). A summary of the principal terms of the Unsecured Credit Facility and the Unsecured Credit Facility's effect on the Company's existing revolving credit term loan facilities is as follows:
•The Unsecured Credit Facility replaced the Company's prior revolving credit and term loan facility evidenced by that certain Fourth Amended and Restated Revolving Credit and Term Loan Agreement dated as of July 20, 2022 by and among the Company, the OP, Wells Fargo Bank, National Association, as Administrative Agent, and the other lenders identified therein, as amended (the “Prior Credit Facility”). All outstanding obligations due under the Prior Credit Facility were reallocated to the lenders under the Unsecured Credit Facility.
•The Company’s $1.5 billion Revolver was continued with a maturity extension from October 31, 2025 to July 25, 2029, with two six-month extension options. The Revolver includes a sublimit of $120 million for letters of credit.
•The previously funded $200 million term loan was continued with a maturity date of January 31, 2026 and three extension options totaling 16 months.
•The previously funded $150 million term loan was continued with a maturity date of June 1, 2026, with two extension options of six months each.
•The previously funded $300 million term loan was continued with a maturity date of October 31, 2025, with four extension options totaling 24 months.
•The previously funded $200 million term loan was continued with a maturity date of July 20, 2027, with two extension options of 12 months each.
•The previously funded $300 million term loan was continued with a maturity date of January 20, 2028, with one extension option of 12 months.
Revolving loans outstanding under the Unsecured Credit Facility bear interest at a floating rate equal to the daily simple Secured Overnight Financing Rate ("SOFR"), term SOFR or base rates, as applicable, plus an applicable margin. The applicable margin is determined based on the Borrower’s credit ratings and ranges from 0.725% per annum to 1.40% per annum (currently 0.84% per annum). Term loans outstanding under the Unsecured Credit Facility bear interest at a rate equal to Term SOFR rates plus an applicable margin. The applicable margin is determined based on the Borrower’s credit ratings and ranges from 0.80% per annum to 1.60% per annum (currently 0.94% or 1.04% per annum). In addition, the Borrower pays a facility fee on the Revolver commitments at a rate per annum determined based on the Borrower’s credit ratings and ranging from 0.125% per annum to 0.30% per annum (currently 0.20% per annum).
Except as set forth above, the principal terms of the Unsecured Credit Facility are substantially consistent with the terms of the Prior Credit Facility. Specifically, the Unsecured Credit Facility contains representations and warranties and affirmative and negative covenants that are customary for facilities of this size and type. These covenants include, among others: limitations on the incurrence of additional indebtedness; limitations on mergers, investments and acquisitions; limitations on dividends and redemptions of capital stock; limitations on transactions with affiliates; and requirements to comply with certain financial covenants, including a maximum consolidated leverage ratio, a maximum consolidated secured leverage ratio, a maximum consolidated unencumbered leverage ratio, a minimum fixed charge coverage ratio and a minimum unsecured coverage ratio.
Subsequent Activity
In February 2026, the Company entered into a commercial paper dealer agreement to issue short-term commercial paper notes up to $600.0 million, with maturities up to 364 days. The program is back-stopped by the Unsecured Credit Facility. The notes will be issued at par less a discount representing an interest factor, or if interest bearing, at par.
