Ladies and Gentlemen:

This letter (this “Agreement”) constitutes the agreement between (a) Oportun Financial Corporation (“Company”) and (b) ▇▇▇▇▇▇▇ Capital Management LLC (“▇▇▇▇▇▇▇”) and each of the other related Persons (as defined below) set forth on the signature pages to this Agreement (each, a “▇▇▇▇▇▇▇ Signatory,” and, collectively, the “▇▇▇▇▇▇▇ Signatories”). Company and the Findell Signatories are collectively referred to as the “Parties.” The ▇▇▇▇▇▇▇ Signatories and each Affiliate (as defined below) and Associate (as defined below) of each ▇▇▇▇▇▇▇ Signatory are collectively referred to as the “▇▇▇▇▇▇▇ Group.”

1. Board Matters.

(a) Director Appointment. Effective as of the date of this Agreement, Company’s Board of Directors (the “Board”) and any applicable committees of the Board will take all action necessary (including increasing the size of the Board) to appoint ▇▇▇▇▇▇ ▇▇▇▇▇▇ (the “New Director”) as a Class III director with a term expiring at Company’s 2028 annual meeting of stockholders (the “2028 Annual Meeting”), with such appointment to be effective one day after the date of Company’s 2025 annual meeting of stockholders (the “2025 Annual Meeting”).

(b) Committee Membership. Subject to applicable law, rule or regulation (including the applicable rules and regulations of the SEC and Nasdaq (each as defined below)), Company agrees that, during the Restricted Period (as defined below), the New Director will be given the same due consideration for membership on any committees of the Board as any other independent director, including any new committee(s) and subcommittee(s) that may be established.

(c) Compliance with Laws and Company Policies. The ▇▇▇▇▇▇▇ Signatories acknowledge that the New Director will be governed by the same laws, policies, procedures, processes, codes, rules, standards and guidelines applicable to members of the Board, including Company’s corporate governance guidelines, code of business conduct and ethics, ▇▇▇▇▇▇▇ ▇▇▇▇▇▇▇ policy, Regulation FD policy and related party transactions policy, in each case, in effect and as amended from time to time (collectively, the “Company Policies”). The Findell Signatories acknowledge that, unless otherwise informed by Company in writing, (a) they do not have the right to receive confidential information concerning the Company from the New Director; and (b) neither Company nor the Board has authorized the New Director to share any such confidential information with any member of the ▇▇▇▇▇▇▇ Group.

(d) No Fiduciary Restriction. Notwithstanding anything to the contrary in this Agreement, Company acknowledges and agrees that nothing in this Agreement will prohibit the New Director, during the New Director’s service as a director of Company, from acting in the New Director’s capacity as a director of Company or from complying with the New Director’s fiduciary duties as a director of Company (including voting on any matter submitted for consideration by the Board, participating in deliberations or discussions of the Board, and making suggestions or raising any issues or recommendations to the Board).

(e) Other Board Changes. Company agrees that at or before Company’s 2026 annual meeting of stockholders (the “2026 Annual Meeting”), one person who joined the Board before February 7, 2024, will have retired from the Board and will not be standing for election as a member of the Board at such annual meeting.

(f) Replacement of New Director. If the New Director (or any Replacement Nominee (as defined below) who has replaced the New Director) is no longer serving on the Board due to death or disability or resigns as a director or otherwise ceases to be a director at any time prior to the conclusion of the 2026 Annual Meeting for any reason and (ii) at such time the ▇▇▇▇▇▇▇ Group beneficially owns shares of Company’s common stock (which shares are determined to be Net Long Shares (as defined below)) representing in the aggregate at least such number of shares of Company’s common stock equal to the Threshold Amount (as defined below), then the ▇▇▇▇▇▇▇ Signatories may identify and propose a replacement therefor (and will consider in good faith any proposed replacements suggested by Company), which the Board will, in good faith, accept or reject, and if there is such a rejection, the ▇▇▇▇▇▇▇ Signatories will have the right to continue to identify and propose replacement candidates until a replacement is mutually agreed upon by Company and the ▇▇▇▇▇▇▇ Signatories (any such replacement, a “Replacement Nominee”). Any Replacement Nominee must (A) be reasonably acceptable to the Board; (B) be qualified to serve as a member of the Board under all Company Policies and applicable legal and regulatory requirements; (C) meet the independence requirements with respect to Company of the listing rules of Nasdaq and all applicable rules of the SEC; (D) have complied with Company’s procedures for new director candidates (including the full completion of a directors and officers questionnaire, undergoing a customary background check, and participating in interviews with the members of the Nominating, Governance and Social Responsibility Committee and the Board); (E) have no material relationship with any member of the ▇▇▇▇▇▇▇ Group (as determined in good faith by the Board); (F) not previously have been nominated or designated to serve as a director of Company or any other Person by any member of the ▇▇▇▇▇▇▇ Group; (G) not be a former director or officer of Company; and (H) serve on no more than a total of three other public company boards. Upon becoming a member of the Board, the Replacement Nominee will succeed to all of the rights and privileges, and will be bound by the terms and conditions, of this Agreement applicable to the New Director and will (subject to meeting the requirements for service on such committees pursuant to Company Policies, the listing rules of Nasdaq and applicable rules of the SEC) be promptly appointed to any committees on which the New Director served.

2. Withdrawal of the Proxy Contest and Related Matters.

(a) Withdrawal of Nominations. The ▇▇▇▇▇▇▇ Group agrees that automatically and without any additional action by any Party, upon the execution of this Agreement by all of the Parties, ▇▇▇▇▇▇▇ Capital Partners LP will be deemed to have irrevocably withdrawn (i) its

(b) Termination of Solicitation. Upon execution of this Agreement, the ▇▇▇▇▇▇▇ Signatories hereby irrevocably agree to take, and to cause all other Restricted Persons (as defined below) to take, all necessary actions to immediately and irrevocably:

(i) cease any and all solicitation and other activities in connection with the Nomination Notice and the 2025 Annual Meeting other than actions in accordance with this Agreement (for the avoidance of doubt, it being understood and agreed that the Findell Signatories will vote, or cause to be voted, all Voting Securities (as defined below) beneficially owned by the ▇▇▇▇▇▇▇ Group at the 2025 Annual Meeting in accordance with paragraph 5); and

(ii) modify, disable and not permit to be re-enabled the website “▇▇▇.▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇▇.▇▇▇” and delete or disable any other social media posts made by or on behalf of any Restricted Person (including any posts made to any accounts on LinkedIn, Facebook, Instagram, TikTok, Snapchat, X (formerly known as Twitter) and YouTube) related, directly or indirectly, to Company, the Nomination Notice and/or the 2025 Annual Meeting.

(c) Cooperation. At the request of the Company, the Findell Signatories agree that they will, and will cause the other Restricted Persons to, directly or indirectly, reasonably cooperate with Company to ensure stockholders vote in accordance with the Board’s recommendations on all proposals to be voted on at the 2025 Annual Meeting and at each annual or special meeting of Company’s stockholders (including any adjournments, postponements or other delays thereof) or in connection with any action by written consent during the Restricted Period.

(d) No Further Actions. The ▇▇▇▇▇▇▇ Signatories irrevocably agree that they will not, and will cause the other Restricted Persons not to, directly or indirectly, (i) take any further action in connection with the solicitation of proxies with respect to the Nomination Notice or otherwise concerning the 2025 Annual Meeting (other than in connection with paragraph 2(a), paragraph 2(c) or paragraph 5); or (ii) vote, cause to be voted or otherwise use any proxies received from any other stockholders of Company in connection with the Nomination Notice or the 2025 Annual Meeting (which proxies the ▇▇▇▇▇▇▇ Signatories will cause to be discarded).

3. Governance Matters. Company covenants that it will not change any of Company’s proposals to be considered by stockholders at the 2025 Annual Meeting, as set forth in Company’s definitive proxy statement filed with the SEC on May 28, 2025.

4. Director Benefits. The New Director will be entitled to the same director benefits as other non-employee members of the Board, including (a) compensation for such director’s service as a director and reimbursement of such director’s expenses incurred after joining the Board, in each case on the same basis as all other non-employee directors of Company; (b) equity-

-3-

based compensation grants and other benefits, if any, on the same basis as all other non-employee directors of Company; and (c) the same rights of indemnification and directors’ and officers’ liability insurance coverage as the other non-employee directors of Company as such rights may exist from time to time.

5. Voting Commitment. During the Restricted Period, at each annual or special meeting of Company’s stockholders (including any adjournments, postponements or other delays thereof) or in connection with any action by written consent, the ▇▇▇▇▇▇▇ Signatories will cause all Voting Securities that are beneficially owned by the ▇▇▇▇▇▇▇ Group and that the ▇▇▇▇▇▇▇ Group has the right to vote to be (a) present for quorum purposes (if applicable) and (b) voted or consented (i) in favor of the election of each person recommended by the Board for election as a director; (ii) against any proposals or resolutions to remove any member of the Board; and (iii) in accordance with the recommendation of the Board on all other proposals or business that may be the subject of stockholder action at such meeting or action by written consent, except that (A) if Institutional Shareholder Services Inc. (“ISS”) and Glass Lewis & Co., LLC (“Glass Lewis”) recommend a vote inconsistent with the recommendation of the Board with respect to any proposals or business (other than the election or removal of directors) at such meeting or action by written consent, then each member of the ▇▇▇▇▇▇▇ Group will be permitted to vote in accordance with such ISS and Glass Lewis recommendation; and (B) each member of the ▇▇▇▇▇▇▇ Group will be permitted to vote in its sole discretion on any proposal with respect to an Extraordinary Transaction (as defined below). The Findell Signatories will use commercially reasonable efforts (including by calling back loaned out shares) to ensure that the ▇▇▇▇▇▇▇ Group has voting power for any Voting Securities owned by the ▇▇▇▇▇▇▇ Group on the record date for each annual or special meeting of Company’s stockholders (including any adjournments, postponements or other delays thereof) or action by written consent.

Company has not taken any actions with respect to any matters related to this Agreement that require disclosure on a Current Report on Form 8-K prior to the date of this Agreement that have not previously been disclosed.

17. Specific Performance; Fees. Each Party acknowledges and agrees that money damages may not be a sufficient remedy for any breach (or threatened breach) of this Agreement by it and that, in the event of any breach or threatened breach of this Agreement, (a) the Party seeking specific performance will be entitled to seek injunctive and other equitable relief, without proof of actual damages; (b) the Party against whom specific performance is sought will not plead in defense that there would be an adequate remedy at law; and (c) the Party against whom specific performance is sought agrees to waive any applicable right or requirement that a bond be posted. Such remedies will not be the exclusive remedies for a breach of this Agreement and will be in addition to all other remedies available at law or in equity. If a Party institutes any legal suit, action, or proceeding against the other Party to enforce this Agreement (or obtain any other remedy regarding any breach of this Agreement) or arising out of or relating to this Agreement, including contract, equity, tort, fraud, and statutory claims, the prevailing Party in the suit, action, or proceeding is entitled to receive, and the non-prevailing Party will pay, in addition to all other

-13-

remedies to which the prevailing Party may be entitled, the reasonable and documented costs and expenses incurred by the prevailing Party in conducting the suit, action, or proceeding, including actual attorneys’ fees and expenses, even if not recoverable by law.

18. Entire Agreement; Binding Nature; Assignment; Waiver. This Agreement constitutes the only agreement between the Parties with respect to the subject matter of this Agreement and it supersedes all prior agreements, understandings, negotiations and discussions, whether oral or written. This Agreement binds, and will inure to the benefit of, the Parties and their respective successors and permitted assigns. No Party may assign or otherwise transfer either this Agreement or any of its rights, interests, or obligations under this Agreement without the prior written approval of the other Party. Any purported transfer requiring consent without such consent is void. No amendment, modification, supplement or waiver of any provision of this Agreement will be effective unless it is in writing and signed by the affected Party, and then only in the specific instance and for the specific purpose stated in such writing. Any waiver by any Party of a breach of any provision of this Agreement will not operate as or be construed to be a waiver of any other breach of such provision or of any breach of any other provision of this Agreement. The failure of a Party to insist upon strict adherence to any term of this Agreement on one or more occasions will not be considered a waiver or deprive that Party of the right to insist upon strict adherence to that term or any other term of this Agreement in the future.

19. Severability. If any provision of this Agreement is held invalid or unenforceable by any court of competent jurisdiction, then the other provisions of this Agreement will remain in full force and effect. Any provision of this Agreement that is held invalid or unenforceable only in part or degree will remain in full force and effect to the extent not held invalid or unenforceable, and this Agreement will otherwise be construed so as to effectuate the original intention of the Parties reflected in this Agreement. The Parties further agree to replace such invalid or unenforceable provision of this Agreement with a valid and enforceable provision that will achieve, to the extent possible, the purposes of such invalid or unenforceable provision.

20. Governing Law; Forum. This Agreement is governed by and will be construed in accordance with the laws of the State of Delaware. Each of the Parties (a) irrevocably and unconditionally consents to the exclusive personal jurisdiction and venue of the Court of Chancery of the State of Delaware and any appellate court thereof (unless the federal courts have exclusive jurisdiction over the matter, in which case the United States District Court for the District of Delaware and any appellate court thereof will have exclusive personal jurisdiction); (b) agrees that it will not challenge such personal jurisdiction by motion or other request for leave from any such court; (c) agrees that it will not bring any action relating to this Agreement or otherwise in any court other than the such courts; and (d) waives any claim of improper venue or any claim that those courts are an inconvenient forum. The Parties agree that mailing of process or other papers in connection with any such action or proceeding in the manner provided in paragraph 23 or in such other manner as may be permitted by applicable law, will be valid and sufficient service thereof.

21. Waiver of Jury Trial. EACH OF THE PARTIES, AFTER CONSULTING OR HAVING HAD THE OPPORTUNITY TO CONSULT WITH COUNSEL, KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVES ANY RIGHT THAT SUCH PARTY MAY HAVE TO A TRIAL BY JURY IN ANY LITIGATION BASED UPON OR ARISING

-14-

OUT OF THIS AGREEMENT OR ANY COURSE OF CONDUCT, DEALING, STATEMENTS (WHETHER ORAL OR WRITTEN), OR ACTIONS OF ANY OF THEM. No Party will seek to consolidate, by counterclaim or otherwise, any action in which a jury trial has been waived with any other action in which a jury trial cannot be or has not been waived.

22. No Third Party Beneficiaries. Except as provided in this Agreement, this Agreement is solely for the benefit of the Parties and is not enforceable by any other Person. No Party may assign its rights or delegate its obligations under this Agreement, whether by operation of law or otherwise, and any assignment in contravention hereof will be null and void.

Each Party and its counsel cooperated and participated in the drafting and preparation of this Agreement, and any and all drafts of this Agreement exchanged among the Parties will be deemed the work product of all of the Parties and may not be construed against any Party by reason of its drafting or preparation. Accordingly, any rule of law or any legal decision that would require interpretation of any ambiguities in this Agreement against any Party that drafted or prepared it is of no application and is expressly waived by each of the Parties, and any controversy over interpretations of this Agreement will be decided without regard to events of drafting or preparation.

25. Counterparts. This Agreement and any amendments to this Agreement may be executed in one or more textually identical counterparts, all of which will be considered one and the same agreement and will become effective when one or more counterparts have been signed by each of the Parties and delivered to the other Parties, it being understood that all Parties need not sign the same counterpart. Any such counterpart, to the extent delivered by fax or .pdf, .tif, .gif, .jpg or similar attachment to electronic mail or by an electronic signature service (any such delivery, an “Electronic Delivery”), will be treated in all manner and respects as an original executed counterpart and will be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party may raise the use of an Electronic Delivery to deliver a signature, or the fact that any signature or agreement or instrument was transmitted or communicated through the use of an Electronic Delivery, as a defense to the formation of a contract, and each Party forever waives any such defense, except to the extent that such defense relates to lack of authenticity.
