KBRA assigns ratings to four classes of notes issued by Upstart Securitization Trust 2025-4 (“UPST 2025-4”), a $480 million consumer loan ABS securitization collateralized by unsecured consumer loans. UPST 2025-4 represents the 48th ABS securitization collateralized by unsecured consumer loans originated through the online platform operated by Upstart Network, Inc. (“Upstart” or the “Company”), a 100% owned subsidiary of the publicly traded entity Upstart Holdings, Inc. (NASDAQ: UPST).

The ratings reflect initial credit enhancement levels of 60.40% for the Class A-1 and Class A-2 notes, 46.65% for the Class B notes, 35.80% for the Class C notes and 20.50% for the Class D notes. Credit enhancement consists of overcollateralization, excess spread, a non-declining cash reserve account and subordination (except for the Class D notes). The collateral pool of UPST 2025-4 includes approximately $600.0 million of unsecured consumer loans where approximately 88.8% of the pool has an original term of 60 months.

KBRA applied its Consumer Loan ABS Global Rating Methodology, as well as its Global Structured Finance Counterparty Methodology and ESG Global Rating Methodology as part of its analysis of the portfolio pool data, underlying collateral pool and capital structure. KBRA considered its operational reviews of Upstart, as well as periodic update calls with the Company. Operative agreements and legal opinions were reviewed prior to closing
