Item 1.01. Entry into a Material Definitive Agreement.

On December 19, 2024, Barclays Commercial Mortgage Securities LLC (the “Depositor”) caused the issuance of the BBCMS Mortgage Trust 2024-5C31, Commercial Mortgage Pass-Through Certificates, Series 2024-5C31 (the “Certificates”), pursuant to a pooling and servicing agreement, dated and effective as of December 1, 2024 (the “Pooling and Servicing Agreement”), among the Depositor, as depositor, Midland Loan Services, a Division of PNC Bank, National Association, as master servicer, LNR Partners, LLC, as special servicer, Computershare Trust Company, National Association, as certificate administrator and as trustee, and Pentalpha Lender Surveillance LLC, as operating advisor and as asset representations reviewer.

The Certificates represent, in the aggregate, the entire beneficial ownership in BBCMS Mortgage Trust 2024-5C31 (the “Issuing Entity”), a common law trust formed on December 19, 2024 under the laws of the State of New York pursuant to the Pooling and Servicing Agreement. The assets of the Issuing Entity consist primarily of 39 commercial, multifamily, leased fee and/or manufactured housing community mortgage loans (the “Mortgage Loans”).

The Mortgage Loan secured by the mortgaged property identified as “Riverwalk West” on Exhibit B to the Pooling and Servicing Agreement (the “Riverwalk West Mortgage Loan”), which is an asset of the Issuing Entity, is part of a whole loan (the “Riverwalk West Whole Loan”) that also includes nine (9) additional pari passu promissory notes which are not assets of the Issuing Entity. Prior to June 30, 2025, the Riverwalk West Whole Loan was being serviced and administered pursuant to the Pooling and Servicing Agreement.

As of June 30, 2025, the Riverwalk West Whole Loan is being serviced and administered pursuant to a pooling and servicing agreement, dated as of June 1, 2025 (the “BMO 2025-5C11 Pooling and Servicing Agreement”), among BMO Commercial Mortgage Securities LLC, as depositor, Midland Loan Services, a Division of PNC Bank, National Association, as master servicer, LNR Partners, LLC, as special servicer, BellOak, LLC, as operating advisor and as asset representations reviewer, Computershare Trust Company, National Association, as certificate administrator, and Computershare Trust Company, National Association, as trustee.

The servicing terms of the BMO 2025-5C11 Pooling and Servicing Agreement applicable to the servicing of the Riverwalk West Mortgage Loan are substantially similar to the terms and conditions of the Pooling and Servicing Agreement applicable to the servicing of the other Mortgage Loans, but will differ in certain respects, as described under “Pooling and Servicing Agreement—Servicing of the Non-Serviced Mortgage Loans” in the Prospectus filed by the Issuing Entity pursuant to Rule 424(b)(2) with respect to the Certificates on December 6, 2024 (the “Prospectus”). The BMO 2025-5C11 Pooling and Servicing Agreement is attached hereto as Exhibit 4.1.
