Item 1.01. Entry into a Material Definitive Agreement.

On May 13, 2025, Barclays Commercial Mortgage Securities LLC (the “Depositor”) caused the issuance of the BBCMS Mortgage Trust 2025-5C34, Commercial Mortgage Pass-Through Certificates, Series 2025-5C34 (the “Certificates”), pursuant to a pooling and servicing agreement, dated and effective as of May 1, 2025 (the “Pooling and Servicing Agreement”), among Barclays Commercial Mortgage Securities LLC, as depositor, Trimont LLC, as master servicer, Argentic Services Company LP, as special servicer, Computershare Trust Company, National Association, as certificate administrator and as trustee, and Pentalpha Surveillance LLC, as operating advisor and as asset representations reviewer.

The Certificates represent, in the aggregate, the entire beneficial ownership in BBCMS Mortgage Trust 2025-5C34 (the “Issuing Entity”), a common law trust formed on May 13, 2025 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 37 commercial, multifamily and/or manufactured housing community mortgage loans (the “Mortgage Loans”).

The Mortgage Loan secured by the mortgaged property identified as “NJ Asden Portfolio” on Exhibit B to the Pooling and Servicing Agreement (the “NJ Asden Portfolio Mortgage Loan”), which is an asset of the Issuing Entity, is part of a whole loan (the “NJ Asden Portfolio Whole Loan”) that also includes two (2) additional pari passu promissory notes which are not assets of the Issuing Entity. Prior to May 16, 2025, the NJ Asden Portfolio Whole Loan was being serviced and administered pursuant to the Pooling and Servicing Agreement.

As of May 16, 2025, the NJ Asden Portfolio Whole Loan is being serviced and administered pursuant to a pooling and servicing agreement, dated as of May 1, 2024 (the “BMO 2025-5C10 Pooling and Servicing Agreement”), between BMO Commercial Mortgage Securities LLC, as depositor, Midland Loan Services, a Division of PNC Bank, National Association, as master servicer, Rialto Capital Advisors, LLC, as special servicer, Park Bridge Lender Services LLC, as operating advisor and as asset representations reviewer, Citibank, N.A., as certificate administrator, and Wilmington Savings Fund Society, FSB, as trustee.

The servicing terms of the BMO 2025-5C10 Pooling and Servicing Agreement applicable to the servicing of the NJ Asden Portfolio 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 April 29, 2025. The BMO 2025-5C10 Pooling and Servicing Agreement is attached hereto as Exhibit 4.1.
