UBS Commercial Mortgage Trust 2018-C15 Reports Special Servicer Change

What Happened

• UBS Commercial Mortgage Trust 2018-C15 filed an 8-K on July 14, 2026 to report a change in special servicing for the Christiana Mall Mortgage Loan. Trimont LLC was removed as special servicer and Green Loan Services LLC was appointed as successor special servicer under the BBCMS 2018-CHRS Trust and Servicing Agreement (dated August 9, 2018). The Christiana Mall loan is part of a loan combination administered under that TSA.

Key Details

• The Christiana Mall Mortgage Loan represented approximately 1.5% of the issuing entity’s asset pool as of the cut-off date.
• The special servicer change is effective July 14, 2026; Green Loan will specially service the loan “if necessary” under the BBCMS 2018-CHRS TSA.
• Successor special servicer: Green Loan Services LLC (principal special servicing office: 1 Vanderbilt Ave, New York, NY 10017; phone: (212) 594-2700).
• The servicing appointment relates to the trust and servicing agreement filed as Exhibit 4.5 to the registrant’s Form 8-K on December 28, 2018.

Why It Matters

• This filing records a change in who handles special servicing duties for the Christiana Mall loan, which may affect how any workout, enforcement or special servicing actions would be managed.
• The loan is a small portion (~1.5%) of the trust’s pool, so the change is likely limited in portfolio impact. No financial terms, transfers of ownership, or borrower-level modifications were disclosed in the filing.
