Key Terms

abs financial

Asset-backed securities (ABS) are financial instruments that bundle many individual loans or receivables—such as car loans, credit-card balances or equipment leases—and sell slices of the bundle to investors. Like slicing a loaf of bread into pieces to share, ABS let investors buy a portion of the cash flows from many borrowers, so their credit quality, payment speed and default rates directly affect the income, risk and liquidity investors receive.

overcollateralization financial

Overcollateralization is the practice of pledging assets worth more than the amount of debt they secure, creating a built-in safety cushion for lenders or bond investors if the underlying assets lose value. Think of it like leaving a larger-than-required security deposit: it lowers the chance investors suffer losses, can improve credit ratings, and usually means lower yields or stricter terms for borrowers because the investment is safer.

excess spread financial

Excess spread is the extra interest income left over after a pool of loans or receivables pays the interest owed to bondholders, servicing fees and expected losses. Think of it as the monthly margin a business keeps after paying suppliers and operating costs — it acts as the first cushion that absorbs losses and supports payments to investors, so larger excess spread reduces investor risk and can boost the safety or return of a securitized deal.

subordination financial

Subordination is the ranking of claims on a company’s assets and payments so that some creditors or investors get paid after others; think of it as a line where subordinated holders stand behind senior holders. It matters to investors because being lower in line means higher risk of losing money if the company can’t meet obligations, which typically requires a higher return or interest to compensate for that added risk.

cutoff date financial

A cutoff date is the specific calendar day a company uses as the deadline to determine who is eligible for a corporate action such as a dividend, vote, stock split, rights offer, or share exchange. Think of it as a snapshot or RSVP deadline: anyone listed as a shareholder by that date gets the benefit or the right, so it directly affects which investors participate and how they should time trades.

NEW YORK--(BUSINESS WIRE)-- KBRA assigns preliminary ratings to four classes of notes issued by Upstart Securitization Trust 2026-3 (“UPST 2026-3”), a $320.005 million consumer loan ABS securitization collateralized by unsecured consumer loans and auto secured personal loans. UPST 2026-3 represents the 51st ABS securitization collateralized by 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 preliminary ratings reflect initial credit enhancement levels of 64.75% for the Class A-1 and Class A-2 notes, 51.05% for the Class B notes, 40.70% 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). As of the June 18, 2026 cutoff date, the collateral pool of UPST 2026-3 will include approximately $400.0 million of loans where auto secured personal loans comprise approximately 2.0% of the pool.

KBRA applied its Consumer Loan ABS Global Rating Methodology as well as its Global Structured Finance Counterparty 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 will be reviewed prior to closing.
