~~BMO~~CWCAM ~~Commercial~~and ~~Mortgage~~its ~~Securities~~affiliates ~~LLC (Depositor)~~are involved in the management, investment management and disposition of commercial real estate assets, which may include:

~~/s/~~· special ~~Paul~~servicing ~~Vanderslice Paul~~of ~~Vanderslice,~~commercial ~~Chief~~and ~~Executive~~multifamily ~~Officer~~real estate loans;

~~Date: March~~· commercial 3,real ~~2025~~estate property management and risk management and insurance services;

· commercial mortgage note and commercial real estate sale and disposition services; and

· investing in, managing, surveilling and acting as special servicer for commercial real estate assets including investment grade, non-investment grade and unrated securities issued pursuant to CRE, CMBS and CDO transactions.

CWCAM was organized in June 2005 and has acted as special servicer for commercial and multifamily loans and other servicing transactions since 2005. CWCAM is a wholly-owned subsidiary of CW Financial Services LLC. CWCAM and its affiliates own, manage and sell assets similar in type to the assets of the issuing entity. Accordingly, the assets of CWCAM and its affiliates may, depending on the particular circumstances including the nature and location of such assets, compete with the mortgaged real properties for tenants, purchasers, financing and so forth. On September 1, 2010, affiliates of certain Fortress Investment Group LLC managed funds purchased all of the membership interest of CW Financial Services LLC, the sole member of CWCAM.

As of December 31, 2023, CWCAM acted as special servicer with respect to 332 domestic CMBS pools containing approximately 10,778 loans secured by properties throughout the United States with a then current unpaid balance of $217 Billion. As of December 31, 2024, CWCAM acted as special servicer with respect to 336 domestic CMBS pools containing approximately 10,183 loans secured by properties throughout the United States with a then current unpaid balance of $211 Billion. As of December 31, 2025, CWCAM acted as special servicer with respect to 330 domestic CMBS pools containing approximately 9,300 loans secured by properties throughout the United States with a then current unpaid balance of $194.7 billion. As of March 31, 2026, CWCAM acted as special servicer with respect to 330 domestic CMBS pools containing approximately 9,250 loans secured by properties throughout the United States with a then current unpaid balance of $193.3 Billion. Those loans include commercial mortgage loans secured by the same types of income producing properties as those securing the underlying mortgage loans.

CWCAM has one primary office (Washington, D.C.) and provides special servicing activities for investments in various markets throughout the United States. As of March 31, 2026, CWCAM had 64 employees responsible for the special servicing of commercial real estate assets. As of March 31, 2026, within the CMBS pools described in the preceding paragraph, 147 assets were actually in special servicing. The assets owned, serviced or managed by CWCAM and its affiliates may, depending on the particular circumstances, including the nature and location of such assets, compete with the mortgaged real properties securing the underlying mortgage loans for tenants, purchasers, financing and so forth. CWCAM does not service or manage any assets other than commercial and multifamily real estate assets.

CWCAM has policies and procedures in place that govern its special servicing activities. These policies and procedures for the performance of its special servicing obligations are, among other things, in compliance with applicable servicing criteria set forth in Item 1122 of Regulation AB under the Securities Act, including managing delinquent loans and loans subject to the bankruptcy of the borrower. Standardization and automation have been pursued, and continue to be pursued, wherever possible so as to provide for continued accuracy, efficiency,

transparency, monitoring and controls. CWCAM reviews, updates and/or creates its policies and procedures throughout the year as needed to reflect any changing business practices, regulatory demands or general business practice refinements and incorporates such changes into its manual. Refinements within the prior three years include but are not limited to the improvement of controls and procedures implemented for property cash flow, wiring instructions and the expansion of unannounced property and employee audits.

CWCAM occasionally engages consultants to perform property inspections and to provide close surveillance on a property and its local market; it currently does not have any plans to engage sub-servicers to perform on its behalf any of its duties with respect to this transaction. CWCAM has made all advances required to be made by it under the servicing agreements on the commercial and multifamily mortgage loans serviced by CWCAM in securitization transactions.

CWCAM will not have primary responsibility for custody services of original documents evidencing the underlying mortgage loans. On occasion, CWCAM may have custody of certain of such documents as necessary for enforcement actions involving particular underlying mortgage loans or otherwise. To the extent that CWCAM has custody of any such documents, such documents will be maintained in a manner consistent with the Servicing Standard.

From time to time, CWCAM is a party to lawsuits and other legal proceedings as part of its duties as a special servicer (e.g., enforcement of loan obligations) and/or arising in the ordinary course of business. Other than as set forth in the following paragraphs, there are currently no legal proceedings pending, and no legal proceedings known to be contemplated by governmental authorities, against CWCAM or of which any of its property is the subject, that are material to the certificateholders.

On December 1, 2017, a complaint against CWCAM and others was filed in the United States District Court for the Southern District of New York styled as CWCapital Cobalt Vr Ltd. v. CWCapital Investments LLC, et al., No. 17-cv-9463 (the “Original Complaint”). The gravamen of the Original Complaint alleged breaches of a contract and fiduciary duties by CWCAM’s affiliate, CWCapital Investments LLC in its capacity as collateral manager for the collateralized debt obligation transaction involving CWCapital Cobalt Vr, Ltd. In total, there are 14 counts pled in the Original Complaint. Of those 14, 5 claims were asserted against CWCAM for aiding and abetting breach of fiduciary duty, conversion and unjust enrichment. On May 23, 2018, the Original Complaint was dismissed for lack of subject matter jurisdiction. On June 28, 2018, CWCapital Cobalt Vr Ltd. filed a substantially similar complaint in the Supreme Court of the State of New York, County of New York styled as CWCapital Cobalt Vr Ltd. v. CWCapital Investments LLC, et al., Index No. 653277/2018 (the “New Complaint”). The gravamen of the New Complaint is the same as the previous complaint filed in the United State District Court for the Southern District of New York. In total there are 16 counts pled in the New Complaint. Of those 16 counts, 5 claims were asserted against CWCAM for aiding and abetting breach of fiduciary duty, conversion and unjust enrichment, 1 count seeks a declaratory judgement that the plaintiff has the right to enforce the contracts in question and 1 count seeks an injunction requiring the defendants to recognize the plaintiff as the directing holder for the trusts in question. On January 11, 2019, the plaintiff dismissed with prejudice the declaratory judgment and injunction counts. The New Complaint and related summons was not served on the defendants until July 13, 2018 and July 16, 2018. The plaintiff’s motion for a preliminary injunction was denied by the court on July 31, 2018. On August 3, 2018, the defendants, including CWCAM, filed a motion to dismiss the New Complaint in its entirety. On August 20, 2019, the court entered an order granting defendants’ motion almost in its entirety, dismissing 11 of the 16 counts and partially dismissing 2 additional counts. Of the remaining counts, 2 are asserted against CWCAM for aiding and abetting breach of fiduciary duty and unjust enrichment. On September 19, 2019, CWCapital Cobalt Vr Ltd. filed a notice of appeal relating to the August 20, 2019 dismissal order and on September 26, 2019, filed an amended complaint against CWCI and CWCAM attempting to address deficiencies relating to certain of the claims dismissed by the August, 20, 2019 order. CWCI and CWCAM filed its Motion to Dismiss the amended complaint on October 28, 2019. The court heard argument on the Motion to Dismiss the amended complaint on January 22, 2020 and on October 23, 2020, the court granted the motion dismissing the amended claims. On November 30, 2020, CWCapital Cobalt Vr Ltd filed a notice of appeal relating to the October 23, 2020 dismissal order. On April 27, 2021, the First Department affirmed the dismissal as to claims against CWCAM that were part of the August 20, 2019 dismissal, but reversed the dismissal of two counts for breach of the Collateral Management Agreement against CWCI. CWCI sought leave to file an appeal of the decision. The plaintiff also sought leave to appeal the dismissal of the claims against CWCAM. Both requests for leave were denied by the First Department. On May 15, 2020, CWCI and CWCAM filed a motion to renew its motion to dismiss as to 4 of the remaining counts (including the remaining two counts against CWCAM for aiding and abetting breach of fiduciary duty and unjust enrichment), based on a decision entered by Judge Failla in a trust instruction proceeding in the US District Court for the Southern District of New York awarding summary judgment in favor of CWCAM. On September 7, 2021, the court denied the motion to renew. CWCI and CWCAM filed a notice of appeal, which they perfected by the filing of their opening brief on July 1, 2022. On November 15, 2022, the First Department affirmed the court’s denial of the motion to renew. On October 1, 2021, CWCI and CWCAM moved to reargue the denial of the motion to renew (or alternatively, the motion to dismiss) with respect to certain of Cobalt’s claims, including the remaining 2 claims against CWCAM, based on the First Department’s April 27, 2021 decision. On March 24, 2022, the court denied the relief sought in the motion to reargue. CWCI and CWCAM appealed the court’s decision on the motion to reargue and filed their opening brief on July 11, 2022. The appeal was dismissed as being non-appealable on August 30, 2022. Discovery (both fact and expert) concluded on March 1, 2024. CWCAM and CWCI filed a motion for summary judgment on March 29, 2024, seeking dismissal of all the claims in their entirety. On that same date, the plaintiff cross moved for summary judgment on one of the claims asserted against only CWCI. Oral argument on the parties’ summary judgment motions were heard on October 22, 2024. . On January 13, 2026, the court denied plaintiff’s motion for summary judgment and granted, in part, and denied, in part, the motion filed by CWCI and CWCAM. Specifically, the court dismissed the remaining two counts against CWCAM for aiding and abetting breach of fiduciary duty and unjust enrichment. With respect to CWCI, the court dismissed two counts against CWCI in their entirety and dismissed portions of one count against CWCI. The only three counts that survived and remain in the case are against CWCI. The court severed the dismissed claims from the surviving claims. On January 22, 2026, CWCI filed a notice of appeal. On February 17, the plaintiff filed a notice of appeal. On January 26, 2026, CWCI and CWCAM submitted an order to the court, requesting that it direct the clerk’s office to enter judgment on the dismissed claims and that CWCAM be dismissed as a defendant from the action. On February 20, 2026, the court entered that order. On April 22, 2026, the clerk’s office entered judgment dismissing CWCAM as a defendant from the action. CWCAM believes that it has performed its obligations under the related pooling and servicing agreements in good faith.

CWCAM may enter into one or more arrangements with any directing certificateholder, any Controlling Class certificateholder, any person with the right to appoint or remove and replace CWCAM as the special servicer, or any other person (or an affiliate or a third-party representative of one or more of the preceding) to provide for a discount and/or revenue sharing with respect to certain of the special servicer compensation in consideration of, among other things, the appointment (or continuance) of CWCAM as special servicer under the Pooling and Servicing Agreement and limitations on the right of such person to replace CWCAM as the special servicer.

No securitization transaction involving commercial or multifamily mortgage loans in which CWCAM was acting as special servicer has experienced an event of default as a result of any action or inaction performed by CWCAM as special servicer. The special servicer ratings of CWCAM are “STRONG” by S&P, “MOR CS1” by DBRS Morningstar and “CSS-“ by Fitch.

A description of additional material terms of the Pooling and Servicing Agreement regarding the role of the special servicer, including limitations on the special servicer’s liability under the Pooling and Servicing Agreement and terms regarding the special servicer’s removal, replacement, resignation or transfer, is included in the Prospectus with respect to the Issuing Entity, dated October 20, 2023 and filed with the Securities and Exchange Commission on October 24, 2023 under Commission File No. 333-255934-08.
