Exhibit 99.1

 

The Subprime Source Since 1991 September 2025 Investor Presentation

SAFE HARBOR STATEMENT Forward - looking statements in this presentation include the Company’s expectations of growth and the Company's recorded figures representing allowances for remaining expected lifetime credit losses, its estimates of fair value (most significantly for its receivables accounted for at fair value), its provision for credit losses, its entries offsetting the preceding, and figures derived from any of the preceding. In each case, such figures are forward - looking statements because they are dependent on the Company’s estimates of losses to be incurred in the future. The accuracy of such statements may be adversely affected by various factors, which include the following: possible increased delinquencies; repossessions and losses on retail installment contracts; incorrect prepayment speed and/or discount rate assumptions; possible unavailability of qualified personnel, which could adversely affect the Company’s ability to service its portfolio; possible increases in the rate of consumer bankruptcy filings, which could adversely affect the Company’s rights to collect payments from its portfolio; other changes in government regulations affecting consumer credit; possible declines in the market price for used vehicles, which could adversely affect the Company’s realization upon repossessed vehicles; economic conditions in geographic areas in which the Company's business is concentrated; and our ability to generate sufficient operating and financing cash flows. Any or all of such factors also may affect the Company’s future financial results, as to which there can be no assurance. Any implication that the results of the most recently completed quarter are indicative of future results is disclaimed, and the reader should draw no such inference. Factors such as those identified above in relation to losses to be incurred in the future may affect future performance. 2
