KBRA assigns preliminary ratings to three classes of notes issued by Navient Refinance Loan Trust 2026-C (“NAVRL 2026-C”), an asset-backed securitization collateralized by private education refinance loans. NAVRL 2026-C will issue three classes of notes totaling $682.80 million. Initial credit enhancement ranges from 15.27% for the Class A Notes to 8.00% for the Class C Notes. Credit enhancement consists of overcollateralization, subordination, and the senior and subordinate reserve accounts.

NAVRL 2026-C represents the sixth private education refinance loan ABS securitization sponsored by Navient Refinance Solutions, LLC (“Navient Refinance Solutions”) under the NAVRL platform, the third in 2026, and the 84th private education loan ABS transaction sponsored by Navient Solutions, LLC and its predecessor entities.

The NAVRL platform was established in 2025 for Navient's private education refinance loan securitizations. The transaction is collateralized by private education refinance loans originated by Earnest Operations LLC (“Earnest”) under the Earnest student loan refinancing program. Navient Holdings, Inc. (“Navient” or the “Company”) is a public company listed on the Nasdaq under the ticker symbol “NAVI,” following an internal reorganization completed on October 28, 2026.

As of October 5, 2026 (the “Statistical Cut-Off Date”), the collateral pool consisted of approximately $742.0 million of private education refinance loans, with a weighted average (“WA”) borrower credit score of 776, WA borrower income of approximately $202,938, and WA original and remaining terms of 163 and 160 months, respectively. Approximately 96.7% of the pool was in repayment.
