We compared Characteristics 2. through 14. to the corresponding information set forth on or derived from the lease agreement, work order notice of commencement or any amendments thereto (collectively, the “Lease Agreement”).

At the instruction of Deutsche Bank, on behalf of the Company, we accessed the “Standard & Poor's Financial Services LLC Website” (https://www.standardandpoors.com) on August 18, 2025. Using the tenant name (as set forth on the Lease Agreement), we compared Characteristic 15. to the corresponding information set forth on Standard & Poor's Financial Services LLC Website.

In addition to the procedures described above, we compared the Tenant Lease’s kw ramp schedule, space and power MRR ramp schedule and pricing ramp schedule, each as set forth on the Data File, to the corresponding information set forth on or derived from the Lease Agreement, for the period beginning May 31, 2025 through the related lease expiration date, and found them to be in agreement.

The tenant lease documents described above and any other related documents used in support of the Characteristics were provided to us by, or on behalf of, the Company and are collectively referred to hereinafter as the “Lease Documents.” We were not requested to perform, and we did not perform, any procedures with respect to the preparation or verification of any of the information set forth on the Lease Documents and we make no representations concerning the accuracy or completeness of any of the information contained therein. In certain instances, our procedures were performed using data imaged facsimiles or photocopies of the Lease Documents. In addition, we make no representations as to whether the Lease Documents are comprehensive or valid instruments or reflect the current prevailing terms with respect to the Tenant Lease.

Agreed-Upon Procedures’ Findings
