(“Origin” or the “Company”); (ii) stockholder Randell Yaden (“Yaden,” together with Plaintiffs, “Settling Stockholders”) who served a litigation demand on behalf of the Origin, dated March 4, 2025, on the Company’s Board of Directors (the “Demand” and, together with the Action, the “Derivative Matters”); (iii) individual defendants John Bissell, Pia Heidenmark Cook, Kathleen B.

This Stipulation is intended by the Settling Parties to fully, finally, and forever resolve, discharge and settle the Released Claims (as defined in paragraph 1.20 below), subject to approval of the United States District Court for the Eastern District of California (the “Court”).1 I. FACTUAL AND PROCEDURAL BACKGROUND Origin is a Delaware corporation, headquartered in West Sacramento, California, specializing in developing and commercializing sustainable materials to replace traditional petroleum-based materials used in various industries. The Company utilizes a proprietary technology to convert biomass into environmentally friendly alternatives to conventional plastics for use in food and beverage packaging, textiles, adhesives, and other applications. ¶ 2.2 The Derivative Matters arise from, inter alia, allegations that the Individual Defendants breached their fiduciary duties as officers and directors of Origin by making materially and/or permitting the issuance of materially false and misleading statements and failing to disclose that the Company was experiencing purported operational issues and delays in the planned buildout and intended use of two manufacturing plants, Origin 1 and Origin 2. ¶¶ 5, 141. A. The Demand On March 4, 2025, stockholder Yaden served a Demand on the Company’s Board of Directors (the “Board”) alleging claims based, inter alia, on the failure to disclose various purported operational issues and the statements regarding Origin 1 and Origin 2. Following this, Counsel for Stockholder and Defendants executed a stipulation to stay the Demand on May 6, 2025. 1 Capitalized words or terms used herein, unless otherwise defined, shall have the meanings ascribed to them in Section V.1. herein titled “Definitions.” 2 “¶__” refers to paragraphs of the Complaint in Kaspar v. Bissell, et al., Case No. 2:25-cv- 00777-WBS-JDP (E.D. Cal.), ECF No. 1.

The Actions On March 7, 2025, Plaintiff Kaspar filed a Verified Shareholder Derivative Complaint against the Individual Defendants (the “Kaspar Action”), asserting claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, abuse of control, waste of corporate assets, and violations of Section 14(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) in connection with an alleged failure to disclose various purported operational issues and the statements concerning Origin 1 and Origin 2. ¶¶ 172-201. On March 10, 2025, Plaintiff Tanasse filed a Verified Shareholder Derivative Complaint against the Individual Defendants (the “Tanasse Action”), asserting claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, and violations of Section 14(a) of the Exchange Act in connection the statements concerning Origin 1 and Origin 2. The Court related the cases and reassigned the Kaspar and Tanasse Actions to Senior District Judge William B. Shubb and Magistrate Judge Jeremy D. Peterson. ECF No. 16. On June 6, 2025, the Court consolidated the Kaspar and Tanasse Actions, appointed Rigrodsky Law, P.A. and Kuehn Law, PLLC as Co-Lead Counsel for Plaintiffs in the consolidated action, and stayed the consolidated action pending a final decision on any summary judgment motion filed by the defendants in In re Origin Materials, Inc. Securities Litigation, Case No. 2:23-cv-01816-WBS- JDP (E.D. Cal.) (the “Securities Class Action”), ECF No. 19. C. Settlement Negotiations In or around July 2025, the Settling Parties commenced negotiations regarding a possible resolution of the claims asserted in the Derivative Matters. In connection therewith, the Settling Stockholders reviewed the Company’s existing corporate governance and prepared a settlement demand which was sent to Defendants on July 23, 2025. Thereafter, the Settling Parties engaged in numerous discussions concerning potential resolution of the Derivative Matters, during which Defendants shared certain confidential information concerning the Company’s operations and financial condition with Settling Stockholders’ Counsel. In addition, the Settling Parties exchanged numerous draft settlement

STIPULATION AND AGREEMENT OF SETTLEMENT 4 Case No.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 proposals informed, in part, by that confidential information. After several weeks of arm’s-length negotiations between counsel, the Settling Parties ultimately reached an agreement to resolve the Derivative Matters (the “Settlement”) through the adoption, implementation, and/or maintenance of corporate governance reforms and cost reduction measures (the “Reforms”) set out in Exhibit A hereto. The Reforms directly address, and seek to remediate, the alleged governance deficiencies that enabled the wrongdoing alleged in the Derivative Matters. If implemented, the Reforms will significantly bolster the Company’s corporate governance policies and practices, substantially enhance the Board’s risk oversight responsibilities and capabilities, and reduce costs for the Company in the near term. Only after agreeing on the Reforms and principal terms of the Settlement did the Settling Parties begin negotiating the attorneys’ fees and expenses to be paid to Settling Stockholders’ Counsel in consideration of the substantial benefits achieved for the Company and its current stockholders through the pendency, prosecution, and settlement of the Derivative Matters and the efforts of counsel for the Settling Stockholders (“Fee and Expense Amount”). After numerous rounds of negotiations, on October 6, 2025, the Settling Parties ultimately agreed to a Fee and Expense Amount in an amount to be approved by the Court but not exceeding $700,000, reflecting the substantial benefits achieved for the Company and its current stockholders through the Derivative Matters. II. SETTLING STOCKHOLDERS’ CLAIMS AND THE BENEFITS OF SETTLEMENT Settling Stockholders and Settling Stockholders’ Counsel believe that the claims asserted in the Derivative Matters have merit, however, they recognize and acknowledge the expense and delay that would result from further litigation to prosecute the Derivative Matters through trial and any possible appeals. Settling Stockholders and Settling Stockholders’ Counsel have also taken into account the risk and uncertainty inherent in all litigation, especially in complex shareholder derivative litigation. Balancing the significant and immediate benefits provided by the Settlement against the speculative possibility that further litigation may result in a one-time

STIPULATION AND AGREEMENT OF SETTLEMENT 5 Case No.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 monetary payment to the Company of uncertain value, as well as the real risk that Company could recover nothing at all, after significant additional costs, delay, and disruption to the Company, Settling Stockholders and Settling Stockholders’ Counsel have determined that the Settlement is in the best interests of Origin and Current Origin Stockholders. III. DEFENDANTS’ DENIAL OF WRONGDOING AND LIABILITY Each Individual Defendant has denied and continues to deny that he or she has committed or attempted to commit any violations of law, any breaches of fiduciary duty owed to Origin, or any wrongdoing whatsoever, and expressly maintains, that at all relevant times, he or she acted in good faith and in a manner that he or she reasonably believed to be in the best interests of the Company and its stockholders. Defendants further deny that the Settling Stockholders, the Company, or its stockholders suffered any damage or were harmed as a result of any act, omission, or conduct by the Individual Defendants as alleged in the Derivative Matters or otherwise. Defendants further assert, among other things, that the Settling Stockholders lack standing to litigate derivatively on behalf of the Company because the Settling Stockholders have not yet pleaded, and cannot properly plead, that a demand on the Board would be futile. Nonetheless, Defendants believe that the Settlement is in the best interests of the Company, its stockholders, and its employees. Defendants have also taken into account the expense, uncertainty, and risks inherent in any litigation, especially in complex cases like the Derivative Matters or other shareholder derivative action(s) or books and records actions, and that the Settlement would, among other things: (a) bring to an end the expenses, burdens, and uncertainties associated with the continued litigation of the claims asserted in the Derivative Matters; (b) put to rest those claims and the underlying Derivative Matters; and (c) avoid disruption of the Individual Defendants’ duties or the Company’s operations due to the pendency and defense of the Derivative Matters. Therefore, Defendants have determined that it is desirable and beneficial that the Derivative Matters, and all of the Settling Parties’ disputes related thereto, be fully and finally settled in the manner and upon the terms and conditions set forth in this Stipulation. Pursuant to the terms set forth below, this Stipulation (including all of the Exhibits

STIPULATION AND AGREEMENT OF SETTLEMENT 6 Case No.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 hereto) shall in no event be construed as or deemed to be evidence of an admission or concession by Defendants with respect to any claim of fault, liability, wrongdoing, or damage whatsoever. Each Individual Defendant has further asserted, and continues to assert, that at all material times, the Individual Defendant acted in good faith and in a manner that she or he reasonably believed to be in the best interests of the Company and its stockholders. IV. INDEPENDENT BOARD APPROVAL OF THE SETTLEMENT Origin’s Board of Directors (the “Board”), including each of the independent, nondefendant members of the Board, advised by counsel and acting by unanimous resolution and in exercise of their business judgment, acknowledges that the Settlement confers substantial benefits upon the Company and its stockholders and that the adoption, implementation, and maintenance of the Reforms are in the best interests of the Company and its stockholders. V.

The costs of any such allocation, mediation or arbitration shall be borne solely by Settling Stockholders’ Counsel and allocated by agreement or as finally determined by the Mediator.

EXHIBIT A

1 1. Duration a. Unless otherwise specified, Origin Materials, Inc. (“Origin” or the “Company”) shall adopt and implement the following governance provisions (the “Reforms”) no later than sixty (60) days after a judgment approving the settlement of the Derivative Action (defined below) is entered by the Court, and after the expiration of the time for any appeals therefrom (“Final Settlement Approval”), and shall maintain such Reforms for a period no less than three years. 2. Updates to the Board’s Oversight Functions a. Any prospective financial guidance to be provided to the market and/or publicly disclosed by the Company, including projected revenue, income, expenses, liabilities, losses, margins, and/or other material information required to be disclosed by the United States Securities and Exchange Commission (the “SEC”) in Origin’s public filings, will be reviewed by the Board (or a committee designated by the Board) prior to disclosure. The Board and/or its designated committee shall review the detailed basis for each element of the financial guidance with the Company’s management and approve the issuance of such financial guidance prior to public dissemination. The Board shall memorialize its approval of the financial guidance prior to its release in the Board’s minutes and in a resolution finding that the guidance has a good faith basis. b. Any and all operational information, including information relating to enterprise risk, as well as projections or non-financial metrics, to be provided to the market, or otherwise publicly disclosed by the Company, will be reviewed by the Board (or a committee designated by the Board) prior to disclosure. The Board and/or its designated committee shall work with management, including with the management-level Disclosure Committee, to review the detailed basis for each element of the operational information and/or projections with the Company’s management and approve the issuance of such operational information, projections, and/or non-financial metrics, prior to public dissemination. The Board shall memorialize its approval of the operational information, projections, and/or non-financial metrics prior to its release in the Board’s minutes and in a resolution finding that the information and guidance have a good faith basis. c. If, subsequent to issuance or public dissemination, the Board becomes aware of information or events that materially affect or alter any financial guidance, operational information, projections, or non-financial metrics provided by the Company, the Board shall ensure that a corrective statement or disclosure is promptly issued and publicly disseminated by the Company. d. The Board, or a committee designated by the Board, will evaluate the internal controls related to the review and approval of material contracts and adopt new policies, if needed. e. Each member of the Board shall attend a National Association of Corporate Directors (“NACD”) Certified Program or similar program(s) within one year after Final Settlement Approval and every three years thereafter. Newly elected

2 Board members must attend a program within one year of joining the Board. 3. Creation of a Board Operational Excellence Committee a. The Company shall establish a Board-level Operational Excellence Committee (the “OEC”). The Company shall adopt a Charter for the OEC, which has been drafted by the parties and which shall be available on the Company’s website. b. The purpose of the OEC is not to overlap with any other Committee of the Board, but instead to ensure that the Company’s manufacturing capabilities and processes conform to its target production goals as expressed in public statements. As part of its evaluation, the OEC will consider the production capabilities of the Company, and/or any of its partners, including the sufficiency of its technological, human labor, and equipment necessary to meet any stated production goals. c. The OEC shall be comprised solely of Independent Directors and persons who have no financial or other material interest in any matter to be reviewed. d. Members of the OEC should each have a background and experience appropriate and applicable to their charged responsibilities. e. The approval of the OEC shall be required prior to, or contemporaneously with, any public statement made or authorized by the Company referencing its production capabilities, goals, or targets. The OEC shall not grant any such approval without first fully considering the Company’s abilities to meet any such goals or targets and determining that any authorized public statement is true and accurate. f. In performing its review, the OEC shall be allowed to retain, at the Company’s expense, industry consultants and outside legal counsel as appropriate. 4. Amendments to Audit Committee Responsibilities a. The Company shall adopt a revised Audit Committee Charter substantially in the form provided in Exhibit B, which the parties have drafted and which materially enhances the Audit Committee’s risk oversight responsibilities. b.

Such training will include, but not be limited to, regular continuing education with regard to applicable rules and regulations and related changes or trends and identifying and managing risk.

3 5. Maintaining a Management Disclosure Committee a. The Company shall maintain a management-level Disclosure Committee which, in coordination with the Board and/or its designated committee, shall be responsible for ensuring that the Company’s significant public statements, including SEC filings, press releases and other public statements, are reviewed for accuracy, integrity, and compliance with applicable laws and regulations, as well as generally accepted accounting principles (“GAAP”) and non-GAAP requirements, protocols and procedures. b. The Disclosure Committee membership shall be enhanced by the addition of the Chief Executive Officer (“CEO”). In addition, its members will consist of, at least, the Company’s Chief Financial Officer (“CFO”), CCO, and Director of Marketing Communications (or the employee with the most closely analogous role, should the title change). c. The Disclosure Committee shall also be supplemented by a Board Liaison, selected by the Board from among independent directors. The Board Liaison shall participate in Disclosure Committee proceedings at least once a year, in connection with the preparation of the Company’s annual report on SEC Form 10-K, or more frequently, as appropriate. d.

The Board shall implement and maintain a Public Statements Policy. Among other things, the purpose of the Public Statements Policy is to avoid the publication of

4 false and/or misleading statements or material omissions by Company officers, directors, and/or employees. The newly established Public Statements Policy shall be disseminated to Company officers, directors, employees, and shareholders and published on the Company’s Investor Relations website. 6. Creation of a Chief Compliance Officer a. The Company shall create the formal executive position of Chief Compliance Officer (“CCO”) who shall be charged with the responsibility of overseeing the Company’s corporate governance policies, fostering a culture of compliance and ethics, maintaining a system for accurate public and internal disclosures, and reporting and investigating compliance and ethics concerns to the Board and/or its designated committee. b. The CCO shall implement and/or maintain a robust internal risk training program for all officers, directors, and senior employees of the Company. Such training will include, but not be limited to, regular continuing education with regard to applicable rules and regulations and related changes or trends and identifying and managing risk. c. The CCO shall ensure that all officers, directors, and senior employees re-certify, on an annual basis, their knowledge and compliance with the Code of Business Conduct and Ethics, and further, to confirm that they are not aware of any acts which they believe are not compliance with this Code and applicable laws and regulations. 7. Creation of a Management Product and Technology Committee a. The Company shall establish a management-level Product and Technology Committee (“PTC”) and adopt a charter formally creating and establishing the responsibilities of the PTC. The PTC will evaluate and assess its Charter and its performance annually or upon the occurrence of certain material events. Any changes to the PTC’s Charter must be approved by a majority vote of the PTC. b. The PTC shall be responsible for overseeing the key technological initiatives, including the design, development, implementation, and maintenance of the Company’s core products, and the remediation of problems, issues, and/or related challenges concerning technological initiatives and core products. c. The PTC shall be composed of, at least the VP of R&D or their functional equivalent, or in the absence of a VP of R&D or functional equivalent, the Chief Technology Officer or their functional equivalent, who shall serve as chair until a successor is appointed, and at least two additional appropriate personnel of the Company, selected by the chair with the advice and input from other functional leaders including the VP of Technology, VP of Manufacturing, and the VP of

5 Sales and Business Development, or their functional equivalents. The members of the PTC shall select a chair, to succeed the VP of R&D or Chief Technology Officer, or their functional equivalents, as applicable. d. The PTC’s responsibilities shall include at least the following: i. Meet with the relevant technology teams at least once quarterly, at which time each team shall report to the PTC on the team’s activities, progress, challenges, and developments as they relate to technology and the products for which funding has been approved. ii. Assist the newly constituted Management-level Disclosure Committee with the review and disclosure of material information concerning the performance, capabilities, or other technical details of the Company’s technology and products to ensure that the Company’s public statements about its products comply with applicable laws and regulations. iii. In the event of a material problem with any of the Company’s technology or products: 1. investigate the facts and circumstances leading to the problem; 2. prepare for distribution to the Board and the OEC a suitable briefing that details the investigative process employed by the PTC, and any remedial measures implemented or to be implemented; and 3. inform and consult with the Disclosure Committee if the problem affects, or is likely to affect, the accuracy of any previous public statement disseminated by the Company. iv. In the performance of its duties and responsibilities, the PTC shall appropriate access to Company books, records, facilities, and personnel. v. The PTC shall meet at least quarterly and additionally as necessary or appropriate, and in particular upon the occurrence of an unusual or material event involving the performance of the Company’s products that may require the filing of a Form 8-K report by the Company. Minutes shall be kept of each meeting of the PTC and shall be made available to the members of the Board upon request. 8. Executive Reports a. At each regularly scheduled Board meeting, the Company’s CFO (or designee) shall provide a written briefing regarding the Company’s financial condition and business prospects, including a discussion of the cause of material increases in expenses and liabilities, if any, or material decreases in revenues and earnings, if

6 any. b.

Cost Reduction Initiatives a. The Board will adopt the following measures designed to minimize costs for the Company in the near term: i. All equity awards to officers previously made in connection with milestones associated with the Origin 2 facility will be canceled within 60 days of the Effective Date, and the Company will ensure they are not offset in other forms of compensation; ii.

Updates on Whistleblower Policy a. The Company’s Code of Business Conduct and Ethics provides that the Company does not tolerate retaliation against whistleblowers. To protect and incentivize employees with legitimate concerns regarding the Company’s management, the Board shall require management to maintain a written whistleblower policy (the “Whistleblower Policy”) that will: i. Encourage interested parties to bring forward ethical and legal violations and/or a reasonable belief that ethical and legal violations have occurred to the Audit Committee Chair, the Disclosure Committee, the CCO, Human Resources, the Legal Department, and/or a whistleblower telephone number or website to be established by the Company so that action may be taken to resolve the problem. These complaints shall be reviewed by the CCO and Disclosure Committee and, in the case of complaints raising issues material to the Company’s operations or financial condition, the Audit Committee, in consultation with and under the supervision of the Company’s legal counsel, and presented to the full Board. ii. Effectively communicate that the Company is serious about adherence to

7 its corporate governance policies and that whistleblowing is an important tool in achieving this goal. b. The Whistleblower Policy must require periodic notification to employees, independent contractors, and vendors of the Company of the following: i. Company executives are subject to criminal penalties, including imprisonment, for retaliation against whistleblowers; ii. Whistleblower complaints may be directed to the Audit Committee Chair and the CCO, in addition to the head of Human Resources, the head of the Legal Department, and the whistleblower telephone number or website, and the complaints may be handled by these parties anonymously and, to the extent permitted, in confidence; c. If a whistleblower brings their complaint to an outside regulator or other governmental entity, they will be protected by the terms of the Whistleblower Policy just as if they directed the complaint to the Audit Committee Chair, CCO, Human Resources, Legal Department, and/or the whistleblower phone number or website; d. If an employee is subject to an adverse employment decision as a result of whistleblowing, the employee may file a complaint with the Department of Labor within ninety (90) days of the alleged violation (a failure to report such claims within the 90-day window does not foreclose any other available legal remedy); and e. It is both illegal and against the Company’s policy to discharge, demote, suspend, threaten, retaliate, intimidate, harass, or in any manner discriminate against whistleblowers.

RESPONSIBILITIES The Committee’s responsibility is one of oversight. The members of the Audit Committee are not employees of the Company, and they do not perform, or represent that they perform, the functions of management or the Auditors. The Committee relies on the expertise and knowledge of management and the Auditors in carrying out its oversight responsibilities. The management of the Company is responsible for preparing accurate and complete financial statements in accordance with generally accepted accounting principles (“GAAP”), preparing periodic reports and for establishing and maintaining appropriate accounting principles and financial reporting policies and satisfactory internal control over financial reporting. The Auditors are responsible for auditing the Company’s annual consolidated financial statements and the effectiveness of the Company’s internal control over financial reporting and reviewing the Company’s quarterly financial statements. It is not the responsibility of the Committee to prepare or certify the Company’s financial statements, guarantee the audits or reports of the Auditors or ensure that the financial statements or periodic reports are complete and accurate, conform to GAAP or otherwise comply with applicable laws.

Evaluation and Retention of Auditors. To evaluate the performance of the Auditors, to assess their qualifications (including their internal quality control procedures and any material issues raised by that firm’s most recent internal quality control review or any investigations by regulatory authorities) and to determine whether to retain, or to terminate, the engagement of the existing Auditors, or to appoint and engage a different independent registered public accounting firm, which retention shall be subject only to ratification by the Company’s stockholders (if the Committee or Board elects to submit such retention for ratification by the stockholders). 2. Communication Prior to Engagement. Prior to engagement of any prospective Auditors, to review a written disclosure by the prospective Auditors of all relationships between the prospective Auditors, or their affiliates, and the Company, or persons in financial oversight roles at the Company, that may reasonably be thought to bear on independence, and to discuss with the prospective Auditors the potential effects of such relationships on the independence of the prospective Auditors, consistent with Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence (“Rule 3526”), of the Public Company Accounting Oversight Board (United States) (the “PCAOB”). 3.

Settling Stockholders; defendants John Bissell, Pia Heidenmark Cook, Kathleen B. Fish, William Harvey, Craig A. Rogerson, Jim Stephanou, R. Tony Tripeny, Rich Riley, Karen Richardson, Benno O. Dorer, and Charles Drucker (the “Individual Defendants”); and nominal defendant Origin Materials, Inc. (“Origin” or the “Company,” together with the Individual Defendants, the “Defendants”) (Settling Stockholders and Defendants are collectively referred to herein as the “Settling Parties”) have agreed upon terms to settle the Derivative Matters and, through counsel, have signed a written Stipulation and Agreement of Settlement (“Stipulation”) memorializing those settlement terms. On January 20, 2026, at 1:30 p.m., at the Robert T. Matsui United States Courthouse, 501 I Street, Sacramento, CA 95814, Courtroom 5, the Honorable William B. Shubb will hold a hearing (the “Settlement Hearing”) in the Action. For more details on the Settlement Hearing, including how to attend and object to the Settlement, see Sections VI and VII below. II. SUMMARY OF THE ACTION A. Description of Allegations in the Action Origin is a Delaware corporation, headquartered in West Sacramento, California, specializing in developing and commercializing sustainable materials to replace traditional petroleum-based materials used in various industries. The Company utilizes a proprietary technology to convert biomass into environmentally friendly alternatives to conventional plastics for use in food and beverage packaging, textiles, adhesives, and other applications. Origin produces various chemicals, including a carbon-negative chloromethylfurfural (“CMF”), which can be converted into, inter alia: (i) paraxylene (“PX”), a material that can replace non-sustainable chemicals used in the production of polyethylene terephthalate (“PET”), which is widely used in textiles and plastic bottles; and (ii) furandicarboxylic acid (“FDCA”), a chemical which can be used to produce polyethylene furanoate (“PEF”), a biobased alternative to PET.

NOTICE OF PENDENCY AND PROPOSED SETTLEMENT OF DERIVATIVE ACTION 4 CASE NO.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 On February 17, 2021, the Company announced its intention to invest in two substantial capital projects. Specifically, the Company would be building two commercial-scale plants, referred to as “Origin 1” and “Origin 2.” Origin 1 was expected to be operational by the end of 2022. Origin 2, a significantly larger manufacturing plant, was expected to be operational by mid-2025 and to supply the majority of the Company’s products from 2025 until 2027. The Derivative Matters arise from allegations that the Individual Defendants breached their fiduciary duties as officers and directors of Origin by making and/or permitting the issuance of materially false and/or misleading statements and failing to disclose that: (i) the Company was experiencing chemical fouling issues “at every step” of the process of converting CMF to PX at commercial scale; (ii) the fouling issues were causing substantial delays during the FEL 2 phase of the Origin 2 project; (iii) the Individual Defendants had been planning internally to scale down production of PX at Origin 2 or to shift focus toward another product; (iv) the Individual Defendants had been planning internally to split construction of Origin 2 into two phases; (v) the Company entered into a deal with Avantium N.V. (“Avantium”) to produce FDCA at Origin 2 to compensate for the Company’s difficulties associated with producing PX at scale; (vi) contrary to the timeline repeatedly disseminated by the Individual Defendants, Avantium advised that it would take several years before Origin 2 could become operational with respect to production of FDCA; (vii) despite representations concerning the oversight responsibilities of the Board and its committees, neither adequately monitored the accuracy of the public statements issued on behalf of, or concerning, the Company; (viii) Origin’s internal controls over legal compliance, including all laws and regulations governing the content of the Company’s public disclosures, were inadequate; and (ix) as a result of the foregoing, positive statements concerning the Company’s business, operations, and prospects were materially misleading and lacked a reasonable basis at all relevant times. Settling Stockholders alleged that Origin disclosed that Origin 2 would no longer produce PET derived from PX and would instead focus on producing PEF derived from FDCA, and that construction of Origin 2 would be broken up into two phases, with phase 1 expected to be operational by late-2026 or 2027 and phase 2 expected to be operational by 2028, on August 9,

Thereafter, the price of Origin stock continued to decline, closing at just $0.99 per share on October 31, 2023, an additional 68% decline from the stock’s August 10, 2023 closing price. As a result, a securities fraud class action was filed against the Company and certain of its officers in the case captioned: In re Origin Materials, Inc. Securities Litig., Case No. 2:23-cv-01816-WBS-JDP (E.D. Cal.) (“Securities Class Action”). On March 4, 2025, stockholder Yaden served a Demand on the Company’s Board of Directors (the “Board”), requesting it to “investigate and commence legal proceedings against … former and/or current directors, executive officers and agents of the Company … for breach of fiduciary duties, gross mismanagement, corporate waste, unjust enrichment, and aiding and abetting.” Following this, in an effort to conserve the Company’s resources, counsel for Stockholder and Defendants discussed staying the Demand pending the resolution of an anticipated motion for summary judgment in the Securities Class Action. After negotiating the material terms of the stay, Stockholder and Defendants reached an agreement and executed a stipulation to stay the Demand on May 6, 2025. On March 7, 2025, Plaintiff Kaspar filed a Verified Shareholder Derivative Complaint against the Individual Defendants, asserting claims for breach of fiduciary duty, aiding and abetting breach of fiduciary duty, unjust enrichment, abuse of control, waste of corporate assets, and violations of Section 14(a) of the Securities Exchange Act of 1934 (the “Exchange Act”) (the “Kaspar Action”). On March 10, 2025, Plaintiff Tanasse filed a Verified Shareholder Derivative Complaint against the Individual Defendants, asserting claims for breach of fiduciary duties, unjust enrichment, waste of corporate assets, and violations of Section 14(a) of the Exchange Act (the “Tanasse Action”). On June 5, 2025, the Court consolidated the Kaspar and Tanasse Actions, appointed Rigrodsky Law, P.A. and Kuehn Law, PLLC as Co-Lead Counsel, and stayed the Action.

B. The Settlement Negotiations In or around July 2025, the Settling Parties commenced negotiations regarding a possible resolution of claims asserted in the Derivative Matters. In connection therewith, the Settling Stockholders reviewed the Company’s existing corporate governance and prepared a settlement proposal which was sent to Defendants’ Counsel for Defendants to review on July 23, 2025. Thereafter, the Settling Parties engaged in numerous discussions concerning potential resolution of the Derivative Matters, during which Defendants shared certain confidential information concerning the Company’s operations, financial condition, and business prospects with Settling Stockholders’ Counsel. In addition, the Settling Parties exchanged numerous draft settlement proposals informed, in part, by that confidential information. After several weeks of arm’s-length negotiations between counsel, the Settling Parties ultimately reached an agreement to resolve the Derivative Matters through the adoption, implementation, and/or maintenance of corporate governance reforms and cost reduction measures (the “Reforms”) set out in Exhibit A to the Stipulation. The Reforms directly address, and seek to remediate, the alleged governance deficiencies that enabled the wrongdoing alleged in the Derivative Matters. If implemented, the Reforms will significantly bolster the Company’s corporate governance policies and practices, substantially enhance the Board’s risk oversight responsibilities and capabilities, and reduce costs for the Company in the near term. III. TERMS OF THE PROPOSED DERIVATIVE SETTLEMENT The proposed Settlement, as set forth fully in the Stipulation, requires the Company to adopt, implement, and/or maintain the Reforms that are set out in Exhibit A to the Stipulation. The Reforms shall be maintained for a minimum period of three (3) years from the date of adoption as provided in the Stipulation.

NOTICE OF PENDENCY AND PROPOSED SETTLEMENT OF DERIVATIVE ACTION 7 CASE NO.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 The members of Origin’s Board, including the independent, non-defendant directors, acting by unanimous resolution and in exercise of their business judgment, acknowledges that the Reforms confer substantial benefits upon the Company and its stockholders and that the adoption, implementation, and maintenance of the Reforms are in the best interests of the Company and its stockholders. Defendants also agree that the pendency, prosecution, and settlement of the Derivative Matters and the efforts of counsel for the Settling Stockholders were a material and substantial cause of adoption and implementation of the Reforms which confer substantial benefits on Origin and its stockholders. This summary should be read in conjunction with, and is qualified in its entirety by reference to, the text of the Stipulation, which has been filed with the Court. IV. ATTORNEYS’ FEES AND EXPENSES After the Settling Parties reached an agreement in principle on the material substantive terms to resolve the Derivative Matters, the Settling Parties commenced negotiations regarding the amount of attorneys’ fees and expenses to be paid to Settling Stockholders’ Counsel in consideration of the substantial benefits achieved for the Company and its current stockholders through the pendency, prosecution, and settlement of the Derivative Matters and the efforts of counsel for the Settling Stockholders (“Fee and Expense Amount”). After numerous rounds of negotiations, on October 6, 2025, the Settling Parties agreed to a Fee and Expense Amount in an amount to be approved by the Court but not exceeding $700,000, reflecting the substantial benefits for the Company and its current stockholders through the Derivative Matters. V. REASONS FOR THE SETTLEMENT The Settling Parties believe that the Settlement and each of its terms are fair, reasonable, and in the best interests of the Company and its stockholders, and that the Settlement, including the Reforms, confers substantial and material benefits upon the Company and its stockholders. A. Why Did Settling Stockholders Agree to Settle? Settling Stockholders and Settling Stockholders’ Counsel believe that the claims asserted in the Derivative Matters have merit and that their investigations support the claims asserted.

NOTICE OF PENDENCY AND PROPOSED SETTLEMENT OF DERIVATIVE ACTION 8 CASE NO.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 However, and without conceding the merit of any of Defendants’ defenses or the lack of merit of any of their own allegations, based upon their thorough investigation and evaluation of the relevant evidence, substantive law, procedural rules, and their assessment of the interests of Origin and Current Origin Stockholders, Settling Stockholders and Settling Stockholders’ Counsel have determined that the guarantee of the immediate and substantial benefits to Origin and Current Origin Stockholders provided by the Settlement outweigh the speculative possibility that further litigation may result in a one-time monetary payment to the Company of uncertain value, as well as the real risk that Company could recover nothing at all, after significant additional costs, delay, and disruption to the Company. Settling Stockholders and Settling Stockholders’ Counsel have determined that the Settlement is in the best interests of Origin and Current Origin Stockholders. Settling Stockholders’ Counsel is based upon an investigation relating to the claims and the underlying events alleged in the Derivative Matters, including, but not limited to: (i) reviewing and analyzing Origin’s public filings with the SEC, press releases, announcements, transcripts of investor conference calls, and news articles; (ii) reviewing and analyzing the investigations in publicly-available pleadings against Origin related to the allegations in the Derivative Matters; (iii) reviewing and analyzing the allegations contained in the related Securities Class Action; (iv) researching the applicable law with respect to the claims asserted (or which could be asserted) in the Derivative Matters and the potential defenses thereto; (vi) researching the existing corporate governance policies and practices of the Company; and (vii) is informed by the confidential information concerning the Company’s operations, financial condition, and business prospects provided to Settling Stockholders’ Counsel during settlement negotiations. B. Why Did the Defendants Agree to Settle? Each Individual Defendant has denied and continues to deny that he or she has committed or attempted to commit any violations of law, any breaches of fiduciary duty owed to Origin, or any wrongdoing whatsoever, and expressly maintains, that at all relevant times, he or she acted in good faith and in a manner that he or she reasonably believed to be in the best interests of the Company and its stockholders. Defendants further deny that the Settling Stockholders, the Company, or its

NOTICE OF PENDENCY AND PROPOSED SETTLEMENT OF DERIVATIVE ACTION 9 CASE NO.: 2:25-CV-00777-WBS-JD 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16 17 18 19 20 21 22 23 24 25 26 27 28 stockholders suffered any damage or were harmed as a result of any act, omission, or conduct by the Individual Defendants as alleged in the Derivative Matters or otherwise. Defendants further assert, among other things, that the Settling Stockholders lack standing to litigate derivatively on behalf of the Company because the Settling Stockholders have not yet pleaded, and cannot properly plead, that a demand on the Board would be futile. Nonetheless, Defendants believe that the Settlement is in the best interests of the Company, its stockholders, and its employees. Defendants have also have taken into account the expense, uncertainty, and risks inherent in any litigation, especially in complex cases like the Derivative Matters or other shareholder derivative action(s) or books and records actions, and that the Settlement would, among other things: (a) bring to an end the expenses, burdens, and uncertainties associated with the continued litigation of the claims asserted in the Derivative Matters; (b) put to rest those claims and the underlying Derivative Matters; and (c) avoid disruption of the Individual Defendants’ duties due to the pendency and defense of the Derivative Matters. Therefore, Defendants have determined that it is desirable and beneficial that the Derivative Matters, and all of the Settling Parties’ disputes related thereto, be fully and finally settled in the manner and upon the terms and conditions set forth in this Stipulation. Pursuant to the terms set forth below, this Stipulation (including all of the Exhibits hereto) shall in no event be construed as or deemed to be evidence of an admission or concession by Defendants with respect to any claim of fault, liability, wrongdoing, or damage whatsoever. Each Individual Defendant has further asserted, and continues to assert, that at all material times, the Individual Defendant acted in good faith and in a manner that she or he reasonably believed to be in the best interests of the Company and its stockholders. VI. SETTLEMENT HEARING On January 20, 2026, at 1:30 p.m., at the Robert T. Matsui United States Courthouse, 501 I Street, Sacramento, CA 95814, Courtroom 5, the Honorable William B. Shubb will hold the Settlement Hearing in the Action. At the Settlement Hearing, the Court will consider, pursuant to Federal Rule of Civil Procedure 23.1, whether (i) the terms of the Stipulation should be approved as fair, reasonable, and adequate; (ii) this Notice fully satisfies the requirements of Federal Rule of

The Court may: (i) approve the Settlement, with such modifications as may be agreed to by counsel for the Settling Parties consistent with such Settlement, without further notice to Current Origin Stockholders; (ii) continue or adjourn the Settlement Hearing from time to time, by oral announcement at the hearing or at any adjournment thereof, without further notice to Current Origin Stockholders; and (iii) conduct the Settlement Hearing remotely without further notice to Current Origin Stockholders.
