KBRA assigns preliminary ratings to four classes (seven tranches) of notes issued by Corporate One Auto Receivables Trust 2026-1 (“COART 2026-1”), a prime auto loan ABS transaction.

COART 2026-1 is the inaugural 144A offering arranged by Corporate One Federal Credit Union (“Corporate One”). Originally chartered in 1949, Corporate One is a member-owned, not for profit, federally charted, corporate credit union headquartered in Columbus, Ohio.

COART 2026-1 will issue four classes (seven tranches) of notes totaling $323.34 million. Credit enhancement consists of overcollateralization, excess spread, subordination (except for the Class D), and a reserve account funded at closing.

The collateral supporting the transaction is a pool of motor vehicle retail installment sales contracts that have been originated indirectly by three credit unions – Wright-Patt Credit Union ("WPCU"), Everwise Credit Union ("Everwise"), and Day Air Credit Union ("Day Air"). As of November 30, 2025, approximately 59.7% of the receivables balance was originated by WPCU, 29.9% by Everwise, and 10.5% by Day Air.

KBRA applied its Auto 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 transaction’s underlying collateral pool, the proposed capital structure and Corporate One’s historical static pool data. KBRA considered its operational review of Corporate One. Operative agreements and legal opinions will be reviewed prior to closing.
