KBRA downgrades the ratings of seven classes of certificates and affirms all other outstanding ratings of UBS 2018-C12, a $630.3 million CMBS conduit transaction. The rating actions follow a surveillance review of the transaction, which has exhibited a worsening in pool performance since KBRA's last ratings change in June 2025 including an increase in realized and projected losses. The rating changes also reflect the likelihood of interest shortfalls continuing to reach higher in the capital stack as the special servicer works out the challenged assets in the pool.

As of the July 2026 remittance period, there are six specially serviced assets (20.2% of the pool balance), of which one(3.0%) is REO, two (5.3%) are in foreclosure, and one (7.0%) is 60 days delinquent. KBRA identified 11 K-LOCs (26.3%),including the specially serviced assets. Of the K-LOCs, eight (21.2%) have estimated losses. The K-LOCs are depicted in the table below.
