We have performed the procedures described below related to certain information with respect to a mortgage loan in connection with the proposed offering of certain classes of MP Trust 2026-WTRP, Commercial Mortgage Pass-Through Certificates, Series 2026-WTRP. Morgan Stanley & Co. LLC, Morgan Stanley Capital I Inc. and Morgan Stanley Mortgage Capital Holdings LLC (collectively, the “Company”) are responsible for the information provided to us, including the information set forth in the Data File (as defined herein).

The Company has agreed to the procedures and acknowledged that the procedures performed are appropriate to meet the intended purpose of evaluating the accuracy of certain information set forth in the Data File. Additionally, Barclays Capital Inc. and Barclays Capital Real Estate Inc. (collectively, with the Company, the “Specified Parties”) have agreed to the procedures and acknowledged that the procedures performed are appropriate for their purposes. This report may not be suitable for any other purpose. The procedures performed may not address all of the items of interest to a user of the report and may not meet the needs of all users of the report and, as such, users are responsible for determining whether the procedures performed are appropriate for their purposes. Consequently, we make no representations regarding the appropriateness of the procedures described below either for the purpose for which this report has been requested or for any other purpose.

We performed certain procedures on earlier versions of the Data File and communicated differences prior to being provided the final Data File which was subjected to the procedures described below.

Capitalized terms used but not defined herein are used with the meanings as described in “The Bond Market Association's Standard Formulas for the Analysis of Mortgage-Backed Securities and Other Related Securities.”

Procedures and Findings

On July 30, 2026, representatives of the Company provided us with a computer-generated mortgage loan data file and related record layout (the “Data File”) containing one mortgage loan (the “Mortgage Loan”) that is secured by one mortgaged property (collectively, with the Mortgage Loan, the “Mortgage Asset”).

From June 10, 2026 through July 30, 2026, representatives of the Company provided us with certain Source Documents (as defined in the attached Appendix A) related to the Mortgage Asset.

At your request, for the Mortgage Asset set forth on the Data File, we compared certain characteristics (the “Characteristics” as indicated on Appendix A), except for those Characteristics identified on Appendix A as “Identification purposes only - not applicable,” “None - Company Provided” or “Not applicable,” to

2

the corresponding information set forth on or derived from the corresponding Source Documents and found them to be in agreement.

******

We make no representations as to (i) the actual characteristics or existence of the underlying documents or data comprising the Mortgage Asset underlying the Data File or the conformity of their respective characteristics with those assumed for purposes of the procedures described herein, (ii) whether the Source Documents are comprehensive and valid instruments and reflect the current prevailing terms with respect to the Mortgage Asset, (iii) the existence or ownership of the Mortgage Asset or (iv) the reasonableness of any of the aforementioned assumptions, information or methodologies.

It should be understood that we make no representations as to questions of legal interpretation or as to the sufficiency for your purposes of the procedures enumerated in the preceding paragraphs. Also, such procedures would not necessarily reveal any material misstatement of the information referred to above. We have no responsibility to update this report for events and circumstances that occur subsequent to the date of this report.

We were engaged by the Company to perform this agreed-upon procedures engagement and conducted our engagement in accordance with attestation standards established by the American Institute of Certified Public Accountants (“AICPA”). An agreed-upon procedures engagement involves the practitioner performing specific procedures that the engaging party has agreed to and acknowledged to be appropriate for the purpose of the engagement and reporting on findings based on the procedures performed. We were not engaged to conduct, and did not conduct, an (i) audit conducted in accordance with generally accepted auditing standards or (ii) examination or a review engagement conducted in accordance with attestation standards established by the AICPA, the objective of which would be the expression of an opinion or conclusion, respectively, on the Data File. Accordingly, we do not express such an opinion or conclusion, or any other form of assurance, including reasonable assurance. Had we performed additional procedures, other matters might have come to our attention that would have been reported to you.

We are required to be independent of the Company and to meet our other ethical responsibilities, as applicable for agreed-upon procedures engagements set forth in the Preface: Applicable to All Members and Part 1 – Members in Public Practice of the Code of Professional Conduct established by the AICPA. Independence requirements for agreed-upon procedure engagements are less restrictive than independence requirements for audit and other attestation services.

None of the engagement, procedures or report was intended to address, nor did they address, the (i) conformity of the origination of the assets to stated underwriting or credit extension guidelines, standards, criteria or other requirements, (ii) value of collateral securing such assets or (iii) compliance of the originator of the assets with federal, state, and local laws and regulations.

None of the engagement, procedures or report were intended to satisfy, nor did they satisfy, any criteria for due diligence published by a nationally recognized statistical rating organization.

This report is intended solely for the use and information of the Specified Parties and is not intended to be and should not be used by anyone other than the Specified Parties.

Yours truly,
