EXPLANATORY NOTE

Introduction

In connection with the preparation of the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2024, the Audit Committee (the "Audit Committee") of the Board of Directors of the Company, after discussion with management and the Company's independent registered public accounting firm, Crowe LLP, concluded that the Company's audited consolidated financial statements as of December 31, 2023 and 2022 and for each year in the three year period ended December 31, 2023, and its unaudited consolidated financial statements as of and for the interim periods ended March 31, 2024 and 2023, June 30, 2024 and 2023 and September 30, 2024 and 2023 (collectively, the "Restated Financial Periods") should no longer be relied upon because of errors identified in such financial statements, as described below.

The errors relate to the Company’s accounting for loans originated pursuant to third-party loan origination programs. These programs go back as far as 2012. As part of these programs, the third-party providers offered various credit enhancements with respect to loans originated under the programs, including contributions to reserve accounts, yield maintenance and certain other payments. Historically, the Company accounted for all borrower payments and credit enhancement payments under these programs on a single unit, or net basis, with all such payments presented as interest income representing the Company’s effective yield on the portfolios. The Company has determined that these payments should instead be accounted for on a separate unit of account, or gross basis, with loan yields and interest income recorded at the gross borrower loan rate, credit losses and associated provisions for credit losses recorded on a gross basis over the life of the loans, and with all credit enhancement payments recorded separately as a credit enhancement derivative.

As a result of the above, the Company is restating the consolidated financial statements (i) as of and for the year ended December 31, 2023 and (ii) for the year ended December 31, 2022, as presented in the audited financial statements as of and for the year ended December 31, 2024 in this Annual Report on Form 10-K. The impact of the errors prior to January 1, 2022 has been adjusted through opening equity as of January 1, 2022 in the audited consolidated financial statements presented herein.

These financial statements include audited consolidated financial statements:

•As of and for the year ended December 31, 2024;

•As of and for the year ended December 31, 2023 (restated); and

•For the year ended December 31, 2022 (restated), excluding the consolidated balance sheet.

Additionally, to reflect the impact of the restatement, this Form 10-K includes consolidated financial statements as of and for the quarters and year-to-date periods ended March 31, 2024 and 2023, June 30, 2024 and 2023 and September 30, 2024 and 2023 (unaudited, restated).

This Form 10-K includes more information than normally would be included in an Annual Report on Form 10-K in order to provide a presentation of information related to the restatement of the periods listed above. See Note 25 - Restatement of Prior Period Financial Statements, in the accompanying Consolidated Financial Statements included in Part II, Item 8 for additional information, including the impact on the specific accounts.

Accordingly, with respect to such periods, investors and others should rely only on the financial information and other disclosures contained in this Form 10-K or in our future filings with the SEC, and not on the financial statements of any previously issued or filed reports, earnings releases or similar communications relating to the Restated Financial Periods and 2021.

Safe Harbor Statement Under the Private Securities Litigation Reform Act of 1995

This Annual Report on Form 10-K contains certain “forward-looking statements” within the meaning of, and are intended to be covered by the safe harbor provisions of, the Private Securities Litigation Reform Act of 1995. These forward-looking statements reflect our current views with respect to, among other things, future events and our financial performance. These statements are often, but not always, made through the use of words or phrases such as “may,” “might,” “should,” “could,” “predict,” “potential,” “believe,” “expect,” “continue,” “will,” “anticipate,” “seek,” “estimate,” “intend,” “plan,” “projection,” “goal,” “target,” “outlook,” “aim,” and “would” or the negative version of those words or other comparable words or phrases of a future or forward-looking nature. These forward-looking statements are not historical facts and are based on current expectations, estimates and projections about our industry, management’s beliefs and certain assumptions made by management, many of which, by their nature, are inherently uncertain and beyond our control. Accordingly, we caution you that any such forward-looking statements are not guarantees of future performance and are subject to risks, assumptions, estimates and uncertainties that are difficult to predict. Although we believe that the expectations reflected in these forward-looking statements are reasonable as of the date made, actual results may prove to be materially different from the results expressed or implied by the forward-looking statements.

A number of important factors could cause our actual results to differ materially from those indicated in these forward-looking statements, including those factors identified in Item 1A – "Risk Factors” or Item 7 – "Management’s Discussion and Analysis of Financial Condition and Results of Operations” or the following:
