Re: CONE Commercial Mortgage Trust 2026-ACD6 – Data File Procedures

We have performed the procedures described below on the specified attributes in an electronic data file entitled “CONE 2026-ACD6 Accounting Tape.xlsx” provided by the Company on June 23, 2026 (the “Data File”), containing information on one mortgage loan (the “Mortgage Loan”) and six related properties (the “Properties”) as of July 6, 2026 (the “Cut-off Date”), which we were informed is intended to be included as collateral in the offering by CONE Commercial Mortgage Trust 2026-ACD6, Commercial Mortgage Pass-Through Certificates, Series 2026-ACD6 (the “Certificates”). The Company is responsible for the specified attributes identified by the Company in the Data File.

The Specified Parties have agreed to and acknowledged that the procedures performed are appropriate to meet the intended purpose of assisting the Specified Parties in evaluating the accuracy of the specified attributes in the Data File. This report may not be suitable for any other purpose. No other parties have agreed to or acknowledged the appropriateness of these procedures for the intended purpose or any other purpose.

The procedures performed may not address all the items of interest to a user of this report and may not meet the needs of all users of this report and, as such, users are responsible for determining whether the procedures performed are appropriate for their purposes. We make no representation regarding the appropriateness of the procedures either for the intended purpose or for any other purpose.

Unless otherwise stated, the following definitions have been adopted in presenting our procedures and findings:

Prior to being provided the Data File, we received one or more earlier versions of the data file on which to perform our procedures. In performing those procedures, we identified differences which were communicated to the Company. The Data File represents the revised information reflecting resolution of differences communicated as determined appropriate by the Company. We performed the procedures on the Data File, and the results of those procedures are reflected herein.

The procedures we were instructed by the Company to perform and the associated findings are as follows:

A.   For the Mortgage Loan and Properties included in the Data File, we compared the Compared Attributes in the Data File (except for those with “Provided by the Company” in the “Source Document(s)” column of Attachment A) to the corresponding information included in the Loan Files. The Company indicated that the absence of any of the information in the Loan Files or the inability to agree the indicated information from the Data File to the Loan Files for each of the attributes identified, constituted an exception, except for those Compared Attributes with “Provided by the Company” in the “Source Document(s)” column of Attachment A. The document priority is the order provided by the Company, which is listed in the “Source Document(s)” column of Attachment A, with the highest priority document listed first.

B.   For the Mortgage Loan and Properties included in the Data File, we recomputed the Recomputed Attributes in the Data File using (i) the corresponding information contained in the Data File, and (ii) the Calculation Methodology.

We found such information to be in agreement without exception.

We were engaged by the Company to perform this agreed-upon procedures engagement. We conducted our engagement in accordance with attestation standards established by the American Institute of Certified Public Accountants, which involves us performing the specific procedures agreed to and acknowledged above and reporting on findings based on performing those procedures. We were not engaged to, and did not, conduct an examination or review, the objective of which would be the expression of an opinion or conclusion, respectively, on the specified attributes in the Data File. Accordingly, we do not express such an opinion or conclusion. Had we performed additional procedures, other matters might have come to our attention that would have been reported.

We are required to be independent of the Company and to meet our other ethical responsibilities, in accordance with the relevant ethical requirements related to our agreed-upon procedures engagement.

The procedures performed were applied based on the information included in the Data File and Provided Information, without verification or evaluation of such information by us; therefore, we express no opinion or any other form of assurance regarding (i) the reasonableness of the information provided to us by the Company, (ii) the physical existence of the Mortgage Loan and related Properties, (iii) the reliability or accuracy of the Provided Information which was used in our procedures, or (iv) matters of legal interpretation.

The procedures performed were not intended to address, nor did they address: (i) the conformity of the origination of the Mortgage Loan to stated underwriting or credit extension guidelines, standards, criteria or other requirements, (ii) the value of collateral securing the Mortgage Loan being securitized, (iii) the compliance of the originator of the Mortgage Loan with federal, state, and local laws and regulations, or (iv) any other factor or characteristic of the Mortgage Loan and related Properties that would be material to the likelihood that the issuer of the Certificates will pay interest and principal in accordance with applicable terms and conditions. The procedures performed were not intended to satisfy any criteria for due diligence published by the nationally recognized statistical rating organizations (“NRSROs”).

The terms of our engagement are such that we have no responsibility to update this report because of events and circumstances that may subsequently occur.

This report is intended solely for the information and use of the Specified Parties. It is not intended to be and should not be used by any other person or entity, including investors or the NRSROs, who are not identified in the report as the Specified Parties but may have access to this report as required by law or regulation.
