KeyBank National Association

As of August 29, 2025, KeyBank replaced Rialto as special servicer (the “Special Servicer”) and assumed all of the duties, responsibilities, and liabilities of the Special Servicer under the Pooling and Servicing Agreement. In its capacity as Special Servicer, KeyBank will be responsible for the servicing and administration of the Specially Serviced Mortgage Loans and REO Properties, and in certain circumstances, will review, evaluate and/or provide or withhold consent as to certain major decisions and other transactions relating to the Mortgage Loans when such Mortgage Loans are not Specially Serviced Mortgage Loans, pursuant to the Pooling and Servicing Agreement.

KeyBank is a wholly-owned subsidiary of KeyCorp. KeyBank maintains a servicing office at 11501 Outlook Street, Suite 300, Overland Park, Kansas 66211.

KeyBank also services newly-originated commercial mortgage loans and mortgage loans acquired in the secondary market for issuers of commercial and multifamily mortgage-backed securities, financial institutions and a variety of investors and other third parties. Based on the aggregate outstanding principal balance of loans being serviced as of December 31, 2024, the Mortgage Bankers Association of America ranked KeyBank the third largest commercial mortgage loan servicer for loans related to commercial mortgage-backed securities in terms of total master and primary servicing volume.

KeyBank is approved as the master servicer, primary servicer, and special servicer for commercial mortgage-backed securities rated by Moody’s, S&P, Fitch, and Morningstar DBRS, a credit rating affiliate of DBRS, Inc (“Morningstar DBRS”). Moody’s does not assign specific ratings to servicers. KeyBank is on S&P’s Select Servicer list as a U.S. Commercial Mortgage Master Servicer and as a U.S. Commercial Mortgage Special Servicer, and S&P has assigned to KeyBank the rating of “Strong” as a master servicer, primary servicer, and special servicer. Fitch has assigned to KeyBank the ratings of “CMS1” as a master servicer, “CPS1-” as a primary servicer, and “CSS1-” as a special servicer. Morningstar DBRS has assigned to KeyBank the rankings of “MOR CS1” as master servicer, “MOR CS1” as primary servicer, and “MOR CS1” as special servicer. S&P’s, Fitch’s, and Morningstar DBRS’s ratings of a servicer are based on an examination of many factors, including the servicer’s financial condition, management team, organizational structure, and operating history.

KeyBank’s servicing system utilizes a mortgage-servicing technology platform with multiple capabilities and reporting functions. This platform allows KeyBank to process mortgage servicing activities including: (i) performing account maintenance; (ii) tracking borrower communications; (iii) tracking real estate tax escrows and payments, insurance escrows and payments, replacement reserve escrows and operating statement data and rent rolls; (iv) entering and updating transaction data; and (v) generating various reports. KeyBank generally uses the CREFC^® format to report to trustees and certificate administrators of commercial mortgage-backed securities (CMBS) transactions and maintains a website (www.key.com/key2cre) that provides access to reports and other information to investors in CMBS transactions where KeyBank is the servicer or the special servicer.

KeyBank maintains the accounts it uses in connection with servicing commercial mortgage loans. The following table sets forth the ratings assigned to KeyBank’s deposits and debt obligations.

KeyBank believes that its financial condition will not have any material adverse effect on the performance of its duties under the Pooling and Servicing Agreement and, accordingly, will not have any material adverse impact on the performance of the Mortgage Loans or the performance of the Certificates.

KeyBank has developed policies, procedures and controls for the performance of its master servicing and special servicing obligations in compliance with applicable servicing agreements, servicing standards and the servicing criteria set forth in Item 1122 of Regulation AB. These policies, procedures and controls include, among other things, procedures to (i) notify borrowers of payment delinquencies and other loan defaults, (ii) work with borrowers to facilitate collections and performance prior to the occurrence of a servicing transfer event, (iii) if a servicing transfer event occurs as a result of a delinquency, loss, bankruptcy or other loan default, transfer the subject loan to the special servicer, and (iv) manage delinquent loans and loans subject to the bankruptcy of the borrowers.

KeyBank’s servicing policies and procedures for the servicing functions it will perform under the Pooling and Servicing Agreement for assets of the same type included in this transaction are updated periodically to keep pace with the changes in the CMBS industry. For example, KeyBank has, in response to changes in federal or state law or investor requirements, (i) made changes in its insurance monitoring and risk-management functions as a result of the Terrorism Risk Insurance Act of 2002, as amended and (ii) established a website where investors and mortgage loan borrowers can access information regarding their investments and mortgage loans. Otherwise, KeyBank’s servicing policies and procedures have been generally consistent for the last three years in all material respects.

KeyBank is, as the Special Servicer, generally responsible for the special servicing functions with respect to the Mortgage Loans and any REO Property. KeyBank may from time to time perform some of its servicing obligations under the Pooling and Servicing Agreement through one or more third-party vendors that provide servicing functions such as tracking and reporting of flood zone changes, performing UCC searches, filing UCC financing statements and amendments, appraisals, environmental assessments, property condition assessments, property management, real estate brokerage services and other services necessary in the routine course of acquiring, managing and disposing of any REO Property. KeyBank will, in accordance with its internal procedures and applicable law, monitor and review the performance of any third-party vendors retained by it to perform servicing functions, and KeyBank will remain liable for its servicing obligations under the Pooling and Servicing Agreement as if KeyBank had not retained any such vendors.

KeyBank will not have primary responsibility for custody services of original documents evidencing the Mortgage Loans. KeyBank may from time to time have custody of certain of such documents as necessary for enforcement actions involving the Mortgage Loans or otherwise. To the extent that KeyBank has custody of any such documents for any such servicing purposes, such documents will be maintained in a manner consistent with the Servicing Standard.

No securitization transaction involving commercial or multifamily mortgage loans in which KeyBank was acting as primary servicer or special servicer has experienced a servicer event of default as a result of any action or inaction of KeyBank as primary servicer or special servicer, as applicable, including as a result of KeyBank’s failure to comply with the applicable servicing criteria in connection with any securitization transaction. KeyBank has made all advances required to be made by it under its servicing agreements for commercial and multifamily mortgage loans.

From time to time KeyBank is a party to lawsuits and other legal proceedings as part of its duties as a loan servicer and otherwise arising in the ordinary course of its business. KeyBank does not believe that any lawsuits or legal proceedings that are pending at this time would, individually or in the aggregate, have a material adverse effect on its business or its ability to service the Mortgage Loans pursuant to the Pooling and Servicing Agreement.

KeyBank is not aware of any lawsuits or legal proceedings, contemplated or pending, by governmental authorities against KeyBank at this time.

The Depositor, the Underwriters, the Initial Purchasers, any borrower Affiliate, the Master Servicer, the Trustee and the Certificate Administrator may maintain banking and other commercial relationships with KeyBank and its affiliates.

The Special Servicer may enter into one or more arrangements with the Directing Certificateholder or any other person who has the right to remove, or vote to remove, the Special Servicer, to provide for a discount and/or revenue sharing with respect to certain Special Servicer compensation. The Directing Certificateholder, a Controlling Class Certificateholder and/or other persons or Certificateholders who have the right to remove, or vote to remove, the Special Servicer may further consider any such economic arrangements with the Special Servicer or a prospective replacement special servicer in entering into any decision to appoint or replace such party from time to time, and such considerations would not be required to take into account the best interests of any Certificateholder.

KeyBank or its affiliates may now or in the future own certain classes of certificates. Any such party will have the right to dispose of such certificates at any time.
