SAFE HARBOR STATEMENT Forward - looking statements in this presentation include the Company’s expectations of growth and the Company's allowances for credit losses, fair value estimates, provision for credit losses, and related figures. In each case, such figures are forward - looking statements because they depend on the Company’s estimates of future losses. Actual results may differ due to various factors including: increased delinquencies, repossessions, and losses; incorrect prepayment speed or discount rate assumptions; competition or the loss of dealer relationships or qualified personnel; reduced availability or increased cost of warehouse and securitization funding, including due to interest rate or capital market conditions; increases in consumer bankruptcy filings; changes in government regulations affecting consumer credit; declines in used vehicle prices; economic conditions in geographic areas in the Company's principal markets; and our ability to generate sufficient operating and financing cash flows. Any or all such factors also may affect the Company’s future financial results, as to which there can be no assurance. Results of the most recent quarter are not necessarily indicative of future results. Additional risks are described in the Company's filings with the Securities and Exchange Commission, including its most recent Annual Report on Form 10 - K and subsequent Quarterly Reports on Form 10 - Q. The Company undertakes no obligation to update any forward - looking statement, except as required by law. 2 Company Overview and Investor Presentation - September 2026
