Opinion on the Financial Statements

We have audited the accompanying consolidated balance sheets of Oportun Financial Corporation and subsidiaries (the "Company") as of December 31, 2023 and 2022, the related consolidated statements of operations, changes in stockholders' equity, and cash flows, for each of the two years in the period ended December 31, 2023, and the related notes (collectively referred to as the "financial statements"). In our opinion, the financial statements present fairly, in all material respects, the financial position of the Company as of December 31, 2023 and 2022, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2023, in conformity with accounting principles generally accepted in the United States of America.

We have also audited, in accordance with the standards of the Public Company Accounting Oversight Board (United States) (PCAOB), the Company's internal control over financial reporting as of December 31, 2023, based on criteria established in Internal Control — Integrated Framework (2013) issued by the Committee of Sponsoring Organizations of the Treadway Commission and our report dated March 15, 2024, expressed an unqualified opinion on the Company's internal control over financial reporting.

Basis for Opinion

These financial statements are the responsibility of the Company's management. Our responsibility is to express an opinion on the Company's financial statements based on our audits. We are a public accounting firm registered with the PCAOB and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion.

Fair Value of Financial Instruments — Fair Value Estimate of Unsecured Personal Loans — Refer to Notes 2 and 14 to the financial statements

Critical Audit Matter Description

The Company’s loans receivable at fair value were valued as Level 3 financial instruments. The Company estimates the fair value of the Level 3 loans receivable using a discounted cash flow model based on estimated future cash flows, which considers unobservable inputs that require significant judgment. The model uses inputs that are not observable and inherently judgmental and reflect management’s best estimates of the assumptions a market participant would use to calculate fair value.

We identified the Company’s fair value estimate of unsecured personal loans as a critical audit matter because of the subjective process in determining significant inputs used to estimate the fair value. Auditing management’s estimate of unsecured personal loans receivable at fair value involved exercising subjective and complex judgments, required specialized skills and knowledge, and required an increased extent of audit effort, including obtaining audit evidence of the data sources used to estimate fair value and understanding the assumptions applied and the nature of significant inputs utilized.

How the Critical Audit Matter Was Addressed in the Audit

Our audit procedures related to the Company’s fair value estimate of unsecured personal loans receivable included the following, among others:

•We tested the effectiveness of management’s controls covering the overall estimate and the review of the accuracy and completeness of the underlying unsecured personal loan data utilized in the model calculations.

•We tested the accuracy and completeness of the source information derived from the Company’s loan data, which is used in the valuation model.

•We evaluated the valuation model and related assumptions, including significant unobservable inputs, and underlying loan data used by management.

•With the assistance of our fair value specialists, we developed independent estimates of the unsecured personal loans receivable at fair value and compared our estimates to the Company’s estimates.
