-1- ORIGIN MATERIALS, INC. PROXY STATEMENT FOR 2025 ANNUAL MEETING OF STOCKHOLDERS To Be Held at 7:30 a.m. Eastern Time on Tuesday, May 6, 2025 This Proxy Statement and the enclosed form of proxy are furnished in connection with the solicitation of proxies by our board of directors for use at the 2025 annual meeting of stockholders of Origin Materials, Inc., a Delaware corporation (“Origin” or the “Company”), and any postponements, adjournments or continuations thereof (the “Annual Meeting”). The Annual Meeting will be held on Tuesday, May 6, 2025 at 7:30 a.m. Eastern Time. To facilitate stockholder participation in the Annual Meeting, this year, the Annual Meeting will be held through a live webcast. In order to attend the Annual Meeting, you must register in advance at www.proxyvote.com prior to the deadline of 11:59 p.m. Eastern Time on May 5, 2025. After completing the registration, you will receive a confirmation email, which will include information about when you should expect to receive a unique link to gain access to the Annual Meeting. You will not be able to attend the meeting in person. The Notice of Internet Availability of Proxy Materials (the “Notice”) containing instructions on how to access this Proxy Statement and our annual report is first being mailed or available to stockholders on or about March 26, 2025 to all stockholders entitled to vote at the Annual Meeting. The information provided in the “question and answer” format below is for your convenience only and is merely a summary of the information contained in this Proxy Statement. You should read this entire Proxy Statement carefully. Information contained on, or that can be accessed through, our website is not intended to be incorporated by reference into this Proxy Statement and references to our website address in this Proxy Statement are inactive textual references only. What is Origin? Origin is a technology company with a mission to enable the world’s transition to sustainable materials. Our innovations include PET closures for an estimated global closures market opportunity of greater than $65 billion. Our PET closures enable fully-recyclable PET beverage containers and reduce waste through light- weighting, while providing enhanced performance such as greater oxygen and CO2 barrier properties that can increase shelf-life. Our furanics technologies include our furanics platform for transforming carbon into sustainable materials for a wide range of end products capable of addressing an estimated $1 trillion market opportunity, including food and beverage packaging, clothing, textiles, plastics, car parts, carpeting, tires, adhesives, soil amendments, and fuels. Our Products and Technologies PET Closures Technology Platform Our PET closures and technologies for producing them reflect our mission to enable the world's transition to sustainable materials, as well as our polymer expertise and platform development capability. We are are going to market with what we believe is the first commercially viable PET closure. We anticipate that our PET closure solutions can be transformative for packaging by designing for recycling circularity and improving the performance and sustainability of packaging. Our product candidates for markets include the PCO 1881 compliant PET closure and a tethered PET closure designed to comply with European cap tethering mandates and keep caps connected to bottles.

-2- Our first Origin CapFormer System, a PET closure manufacturing system, successfully completed its Factory Acceptance Test (“FAT”), which involves a series of tests performed on the system to ensure that the system meets the requirements and functions as intended, in September 2024. Since September 2024, our CapFormer System has produced caps for commercial qualification and has been delivered to our operations and manufacturing center in Reed City, Michigan, where it commenced commercial production in February 2025. We anticipate bringing online additional CapFormer Systems as part of our scale-up strategy. In February 2025, we announced that three new CapFormer lines were nearing completion, with eight total lines expected by the end of December 2025. Furanics Technologies Including Biomass Conversion Platform In addition to our closures business, we have developed a number of technologies related to furanics, a class of chemicals with properties enabling the production of widespread and valuable materials, like plastics. These include our proprietary technology for transforming biomass, or plant-based carbon, into versatile intermediate chemicals. These intermediate chemicals include chloromethylfurfural ("CMF") and hydrothermal carbon (“HTC”), which we collectively refer to as Furanic Intermediates, as well as oils and extractives and other co-products. We believe that products made using our furanics technology at sufficient scale and maturity can compete directly with petroleum-derived products on both performance and price while being sustainable and lowering the carbon footprint.

-3- CMF is a chemically flexible intermediate that can be converted into a variety of products, including numerous commodity and specialty chemicals. Applications include paraxylene (“PX”), which is a precursor to purified terephthalic acid (“PTA”) and subsequently PET; furandicarboxylic acid (“FDCA”), which can be converted into polyethylene furanoate (“PEF”). CMF target markets include food and beverage packaging, apparel, carpet fibers, adhesives, coatings and plasticizers. HTC is a diverse, high-potential material. Current applications of our HTC include a drop-in, energy-dense solid fuel. Our HTC product development pipeline includes carbon black replacement for tires, foams and dyes, paint and coating applications, and agriculture and soil products. Further, we believe oils and extractives could be used to produce cellulose-derived, low carbon intensity biofuels for transportation and marine fuel, industrial applications, and heat and power generation. We continue to perform development work related to our furanics technology. Origin 1, our plant in Sarnia, Ontario, Canada, is currently operating “on demand” with reduced staffing, while preserving our ability to generate product at small volumes sufficient to explore scale-up with strategic partners. This decision was made in alignment with our near-term focus on PET closures as our path to profitability and our asset light strategy for our future plant to further scale up furanics technology. For our future plan, we have explored a variety of plant designs and conducted testing and optimization of various feedstocks to generate data that could influence our scale-up strategy. Corporate History On June 25, 2021, Artius Acquisition Inc. (“Artius”) completed a merger with Micromidas, Inc. (“Legacy Origin,” now known as Origin Materials Operating, Inc., “Origin Operating”). Upon closing of the transactions (the “Business Combination”), Artius acquired 100% of the issued and outstanding common shares of Origin Operating in exchange for shares of common stock of Artius, and Origin Operating became a wholly owned subsidiary of Artius. Upon the closing of the Business Combination, we changed our name from Artius Acquisition Inc. to Origin Materials, Inc. The executive officers of Artius resigned, and the executive officers of Origin Operating were appointed to be the executive officers of Origin Materials, Inc. In addition, certain members of the Artius board of directors and Origin Operating board of directors resigned in connection with the Business Combination. What matters am I voting on? You will be voting on the following proposals: • the election of three Class I directors as named in this Proxy Statement to serve until our 2026 annual meeting of stockholders; • the ratification of the appointment of Deloitte as our independent registered public accounting firm for our fiscal year ended December 31, 2025; • the approval, on a non-binding, advisory basis, of the compensation of our named executive officers; and • any other business as may properly come before the Annual Meeting. As of the date of this Proxy Statement, we are not aware of any other matters that will be presented for consideration at the Annual Meeting. How does the board of directors recommend I vote on these proposals? Our board of directors recommends a vote: • “FOR” the election of Pia Heidenmark Cook, William J. Harvey, and Craig A. Rogerson as Class I directors; • “FOR” the ratification of the appointment of Deloitte as our independent registered public accounting firm for our fiscal year ended December 31, 2025; and

-4- • “FOR” the approval, on a non-binding, advisory basis, of the compensation of our named executive officers, as disclosed in this Proxy Statement. Who is entitled to vote? Holders of our common stock as of the close of business on March 10, 2025, the record date for the Annual Meeting (the “Record Date”), will be entitled to notice of and to vote at the Annual Meeting. Registered Stockholders. If on the Record Date, shares of our common stock are registered directly in your name with our transfer agent, you are considered the stockholder of record with respect to those shares and the Notice was provided to you directly by us. As the stockholder of record, you have the right to grant your voting proxy directly to the individuals listed on the proxy card or vote in person at the Annual Meeting. Throughout this Proxy Statement, we refer to these registered stockholders as “stockholders of record.” Street Name Stockholders. If on the Record Date, shares of our common stock are held on your behalf in a stock brokerage account, or by a bank, trustee or other nominee, you are considered the beneficial owner of shares held in “street name,” and the Notice was forwarded to you by your broker or nominee, who is considered the stockholder of record with respect to those shares. As the beneficial owner, you have the right to direct your broker, bank or other nominee as to how to vote your shares and are also invited to attend the Annual Meeting. However, since a beneficial owner is not the stockholder of record, you may not vote your shares of our common stock in person at the Annual Meeting unless you follow your broker or nominee’s procedures for obtaining a legal proxy. Your broker or nominee is obligated to provide you with instructions to vote before the Annual Meeting or to obtain a legal proxy if you wish to vote in person at the Annual Meeting. If your broker or nominee is participating in an online program that allows you to vote over the Internet or by telephone, your Notice or other voting instruction form will include that information. If what you receive from your broker or other nominee does not contain Internet or telephone voting information, please complete and return the paper form in the self-addressed, postage paid envelope provided by your broker or nominee. Throughout this Proxy Statement, we refer to stockholders who hold their shares through a broker, bank, trustee or other nominee as “street name stockholders.” A list of stockholders of record entitled to vote shall be available to any stockholder for any purpose relevant to the Annual Meeting for 10 days prior to the Annual Meeting upon request to the Office of the Corporate Secretary. Please send the request to Origin Materials, Inc., Attention: Secretary, 930 Riverside Parkway, Suite 10, West Sacramento, California 95605. What constitutes a quorum for the Annual Meeting? A quorum is required for stockholders to conduct business at the Annual Meeting. The presence, in person or represented by proxy, of the holders of a majority of the outstanding shares of our common stock is necessary to establish a quorum at the meeting. As of the close of business on the Record Date, there were 149,456,676 shares of our common stock outstanding. Shares present, in person or represented by proxy, including shares as to which authority to vote on any proposal is withheld, shares abstaining as to any proposal and broker non- votes (where a broker submits a properly executed proxy but does not have authority to vote a stockholder’s shares) on any proposal will be considered present at the meeting for purposes of establishing a quorum. How many votes do I have? In deciding all matters at the Annual Meeting, each stockholder will be entitled to one vote for each share of our common stock held by them on the Record Date. Stockholders are not permitted to cumulate votes with respect to the election of directors.

-5- How many votes are needed to approve each proposal? • Proposal No. 1: The election of directors requires a plurality vote of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote generally on the election of directors. “Plurality” means that the nominees who receive the largest number of votes cast “FOR” are elected as directors. Any shares not voted “FOR” a particular nominee (as a result of an abstention or a broker non-vote) will not be counted in such nominee’s favor and will have no effect on the outcome of the election. You may vote “For” or “WITHHOLD” on each of the nominees. • Proposal No. 2: The ratification of the appointment of Deloitte requires the affirmative vote of a majority of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote on the matter. “Majority” means the number of shares voted “FOR” must exceed the number of votes “AGAINST.” Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote “AGAINST.” Broker non-votes will have no effect on the outcome of this proposal. • Proposal No. 3: The determination, on a non-binding, advisory basis, of our stockholders’ preference regarding the compensation of our named executive officers requires a majority vote of the shares of our common stock present in person or represented by proxy at the Annual Meeting and entitled to vote on the matter. You may indicate whether you approve, on a non-binding advisory basis, of the compensation of our named executive officers, or you may “abstain” from voting on the proposal. “Majority” means the number of shares voted “FOR” must exceed the number of votes “AGAINST.” Abstentions are considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote “AGAINST.” Broker non-votes will have no effect on the outcome of this proposal. How do I vote? If you are a stockholder of record, there are three ways to vote: • By Internet: You may submit a proxy over the Internet by following the instructions at www.proxyvote.com, 24 hours a day, seven days a week, until 11:59 p.m. Eastern Time on May 5, 2025 (have your Notice or proxy card in hand when you visit the website); • By Toll-free Telephone: You may submit a proxy by calling 1-800-690-6903 24 hours a day, seven days a week, until 11:59 p.m. Eastern Time on May 5, 2025 (have your Notice or proxy card in hand when you call); or • By Mail: You may complete, sign and mail your proxy card (if you received printed proxy materials) which must be received by us by 11:59 p.m. Eastern Time on May 5, 2025. If you are a street name stockholder, you will receive voting instructions from your broker, bank or other nominee. You must follow the voting instructions provided by your broker, bank trustee or other nominee in order to instruct your broker or other nominee on how to vote your shares. Street name stockholders should generally be able to vote by returning an instruction card, by telephone or by Internet. However, the availability of telephone and Internet voting will depend on the voting process of your broker or other nominee. As discussed above, if you are a street name stockholder, you may not vote your shares in person at the Annual Meeting unless you obtain a legal proxy from your broker, bank, trustee or other nominee.

-6- Can I change my vote after submitting my proxy? Yes. If you are a stockholder of record, you can change your vote or revoke your proxy any time before date of the Annual Meeting in any one of the following ways: • You may enter a new vote by Internet or by telephone until 11:59 p.m. Eastern Time on May 5, 2025; • You may submit another properly completed, proxy card by mail with a later date, which must be received by us by 11:59 p.m. Eastern Time on May 5, 2025; or • You may send written notice that you are revoking your proxy to our Secretary at Origin Materials, Inc., 930 Riverside Parkway, Suite 10, West Sacramento, California 95605, which must be received by us by 11:59 p.m. Eastern Time on May 5, 2025. If you are a street name stockholder, your broker or nominee can provide you with instructions on how to change your vote. What is the effect of giving a proxy? Proxies are solicited by and on behalf of our board of directors. Our board of directors has designated John Bissell, Matt Plavan, and Joshua Lee as proxy holders. When proxies are properly dated, executed and returned, the shares represented by such proxies will be voted at the Annual Meeting in accordance with the instructions of the stockholder. If no specific instructions are given, however, the shares will be voted in accordance with the recommendations of our board of directors as described under “How does the board of directors recommend I vote on these proposals?” above. If any matters not described in this Proxy Statement are properly presented at the Annual Meeting, the proxy holders will use their own judgment to determine how to vote the shares. If the Annual Meeting is adjourned to a later date, the proxy holders can vote the shares on the new Annual Meeting date as well, unless you have properly revoked your proxy instructions before the new date, as described above. Why did I receive a Notice of Internet Availability of Proxy Materials instead of a full set of proxy materials? In accordance with the rules of the Securities and Exchange Commission (“SEC”), we have elected to furnish our proxy materials, including this Proxy Statement and our annual report, primarily via the Internet. The Notice containing instructions on how to access our proxy materials is first being mailed on or about March 26, 2025 to all stockholders entitled to vote at the Annual Meeting. Stockholders may request to receive all future proxy materials in printed form by mail or electronically by e-mail by following the instructions contained in the Notice. We encourage stockholders to take advantage of the availability of our proxy materials on the Internet to help reduce the environmental impact of our annual meetings of stockholders. How are proxies solicited for the Annual Meeting and who will bear the cost of this solicitation? Our board of directors is soliciting proxies for use at the Annual Meeting. All expenses associated with this solicitation will be borne by us. We will reimburse brokers or other nominees for reasonable expenses that they incur in sending our proxy materials to you if a broker or other nominee holds shares of our common stock on your behalf. In addition, our directors and employees may also solicit proxies in person, by telephone, or by other means of communication. Our directors and employees will not be paid any additional compensation for soliciting proxies. How may my brokerage firm or other nominee vote my shares if I fail to provide timely directions? Brokerage firms and other nominees, for example banks or agents, holding shares of our common stock in street name for their customers are generally required to vote such shares in the manner directed by their

-7- customers. In the absence of timely directions, your broker will have discretion to vote your shares on Proposal No. 2, a “routine” matter, but brokers and nominees cannot use their discretion to vote “uninstructed” shares with respect to matters that are considered “non-routine” under the rules of the New York Stock Exchange (“NYSE”). “Non-routine” matters are matters that may substantially affect the rights or privileges of stockholders, such as mergers, stockholder proposals, election of directors (even if not contested), executive compensation (including any advisory stockholder vote on executive compensation) and certain corporate governance proposals, even if management supported. Accordingly, your broker or nominee may not vote your shares on Proposals No. 1 or No. 3 without your instructions, but may vote your shares on Proposal No. 2. Where can I find the voting results of the Annual Meeting? We will announce preliminary voting results at the Annual Meeting. We will also disclose voting results on a Current Report on Form 8-K (“Form 8-K”) that we will file with the SEC within four business days after the Annual Meeting. If final voting results are not available to us in time to file a Form 8-K within four business days after the Annual Meeting, we will file a Form 8-K to publish preliminary results and will provide the final results in an amendment to the Form 8-K as soon as they become available. What is the deadline for stockholders to propose actions for consideration at next year’s annual meeting of stockholders or to nominate individuals to serve as directors? Stockholder Proposals Stockholders may present proper proposals for inclusion in our Proxy Statement and for consideration at the next annual meeting of stockholders by submitting their proposals in writing to our Secretary in a timely manner. For a stockholder proposal to be considered for inclusion in our Proxy Statement for our 2026 annual meeting of stockholders, our Secretary must receive the written proposal at our principal executive offices not later than November 26, 2025. In addition, stockholder proposals must comply with the requirements of Rule 14a-8 regarding the inclusion of stockholder proposals in company-sponsored proxy materials. Stockholder proposals should be addressed to: Origin Materials, Inc. Attention: Secretary 930 Riverside Parkway, Suite 10, West Sacramento, California 95605 Our amended and restated bylaws also establish an advance notice procedure for stockholders who wish to present a proposal before an annual meeting of stockholders but do not intend for the proposal to be included in our Proxy Statement. Our amended and restated bylaws provide that the only business that may be conducted at an annual meeting of stockholders is business that is (i) specified in our proxy materials with respect to such meeting, (ii) otherwise properly brought before such meeting by or at the direction of our board of directors, or (iii) properly brought before such meeting by a stockholder of record entitled to vote at the annual meeting who has delivered timely written notice to our Secretary, which notice must contain the information specified in our amended and restated bylaws. To be timely for our 2026 annual meeting of stockholders, our Secretary must receive the written notice at our principal executive offices: • not earlier than the close of business on January 6, 2026 and • not later than the close of business on February 5, 2026.

-8- In the event that we hold our 2026 annual meeting of stockholders more than 30 days before or more than 30 days after the one-year anniversary of the Annual Meeting, notice of a stockholder proposal that is not intended to be included in our Proxy Statement must be received no earlier than the close of business on the 120th day before our 2026 annual meeting of stockholders and no later than the close of business on the later of the following two dates: • the 90th day prior to our 2026 annual meeting of stockholders; or • the 10th day following the day on which public announcement of the date of our 2026 annual meeting of stockholders is first made. If a stockholder who has notified us of his, her or its intention to present a proposal at an annual meeting does not appear to present his, her or its proposal at such annual meeting, we are not required to present the proposal for a vote at such annual meeting. Nomination of Director Candidates You may propose director candidates for consideration by our Nominating and Corporate Governance Committee. Any such recommendations should include the nominee’s name and qualifications for membership on our board of directors and should be directed to our Secretary at the address set forth above. For additional information regarding stockholder recommendations for director candidates, see “Board of Directors and Corporate Governance—Stockholder Recommendations for Nominations to the Board of Directors.” In addition, our amended and restated bylaws permit stockholders to nominate directors for election at an annual meeting of stockholders. To nominate a director, the stockholder must provide the information required by our amended and restated bylaws and send timely notice to our Secretary in accordance with our amended and restated bylaws, which, in general, require that the notice be received by our Secretary within the time periods described above under “Stockholder Proposals” for stockholder proposals that are not intended to be included in a Proxy Statement. In addition to satisfying the foregoing requirements under our amended and restated bylaws, a stockholder who intends to solicit proxies in support of director nominees other than the Company’s nominees must comply with the additional requirements of Rule 14a-19(b) under the Exchange Act. Availability of Bylaws Our bylaws are part of our public filings on the SEC’s website at www.sec.gov. You may also contact our Secretary at our principal executive offices for a copy of the relevant bylaw provisions regarding the requirements for making stockholder proposals and nominating director candidates.

Ms. Cook received a Technical Licentiate degree and a M.Sc. in Environmental Management from the University of Lund, Sweden, and a M.Sc. in International Business Administration and Economics from Uppsala University, Sweden. We believe that Ms. Cook’s extensive experience in sustainability and corporate social responsibility qualifies her to serve as our director. William J.

Mr. Harvey received an MBA from the Darden School at the University of Virginia and a B.S. in Economics from Virginia Commonwealth University. We believe that Mr. Harvey’s broad experience as an executive and board member in the packaging and materials industries qualify him to serve as our director. Craig A. Rogerson became a member of Origin’s board of directors beginning on May 1, 2023. Mr. Rogerson has four decades of executive experience leading private and publicly held specialty chemical companies. He served as Chairman, President and Chief Executive Officer of Hexion Inc., a leading global

Mr. Rogerson holds a chemical engineering degree from Michigan State University, and continues to serve on the Michigan State University College of Engineering Alumni board and on the advisory board of the Michigan State University Chemical Engineering & Materials Science Department. We believe that Mr. Rogerson is qualified to serve on our board of directors given his extensive leadership experience with manufacturing companies. Continuing Directors For a biography of Mr. Bissell, please see the section above titled “—Executive Officers.” John Hickox joined the Company’s board of directors and was appointed Chair of the Audit Committee in March 2024 following a distinguished career spanning 40 years in auditing, accounting, FP&A, corporate governance, and executive leadership. Most recently, he assisted Kaizen Analytics, LLC in a contract COO capacity from June 2021 to April 2022. Mr. Hickox was a senior advisory partner at KPMG from May 2004 until he retired in September 2017, where he serviced a range of public clients (mid range to Fortune 10), including chemical and packaging industry clients, in the areas of Sarbanes-Oxley / regulatory compliance, internal audit / risk management, as well as spearheading the KPMG Americas Sustainability Practice, focusing on impactful corporate stewardship, strategy, reporting and profit maximization. From December 1997 to October 2002, Mr. Hickox served as an advisory partner at Ernst & Young where he served clients with their Internal Audit functions with a strong focus on operational improvement, as well as the lead partner on key accounts. Mr. Hickox received a B.B.A. in Accounting from Texas A&M University. We believe that Mr. Hickox’s experience in auditing, accounting, FP&A, corporate governance, and executive leadership, including advising companies in the chemical packaging industries, qualifies him to serve as our director. Jim Stephanou has served on Origin’s board of directors since June 2023. Mr. Stephanou is Chief Executive Officer for IPS (Integrated Project Services) and brings over thirty years of experience in manufacturing operations and engineering, including his current role as CEO of IPS, an engineering and construction services provider to the life sciences sector.

Mr. Stephanou joined Lyondell Basell Industries N.V. in 1988 and held a variety of supervisory positions with the company before being named Manager of Maintenance and Reliability in 2000. Mr. Stephanou holds a mechanical engineering degree from Drexel University. We believe that Mr. Stephanou’s experience in manufacturing operations and engineering qualifies him to serve as our director. Kathleen B. Fish has served on Origin’s board of directors since June 2021 and as Chair of the Compensation Committee since February 2023. Ms. Fish served as Chief Research, Development and Innovation Officer of Procter & Gamble, a consumer goods company, from February 2014 until December 2020.

Ms. Fish is currently a member of the board of directors of USA Swimming and has served on the board of directors of Balchem, an industrial gas company, since June 2021. Ms. Fish received a B.S. in Chemical Engineering from Michigan State University. We believe that Ms. Fish’s leadership experience in the consumer goods industry qualifies her to be on our board of directors. R. Tony Tripeny has served as Chair of Origin’s board of directors since March 2024, and has served as a member of Origin’s board of directors beginning May 1, 2023. Previously from May 1, 2023 through March 1, 2024, Mr. Tripeny also served as Chair of the Audit Committee. Mr. Tripeny brings over three decades of significant operational, strategy, and M&A experience, extensive knowledge of the manufacturing, technology, and materials science industries, and a background in international corporate finance. Since 2022, he has served as a director at Mesa Laboratories, Inc., a global leader in the design and manufacturing of life science tools and critical quality control solutions. Mr. Tripeny has also served the board of IperionX Ltd., a titanium metal and critical materials company, since March 2025.

Mr. Tripeny holds an economics degree from the University of Pennsylvania’s Wharton School of Business and is a member of the Financial Executives Institute and the Institute of Management Accounting. We believe that Mr. Tripeny’s leadership experience and knowledge of corporate finance qualify him to serve on our board of directors. Board Leadership Structure We believe that all members of our board of directors should have a voice in the affairs and the management of Origin. The board of directors believes that our stockholders are best served at this time by having a chairperson, who is an integral part of our board of directors structure and a critical aspect of effective corporate governance. Mr. Tripeny is the chairperson of our board of directors, and has served as such since March 1, 2024. Mr. Tripeny brings considerable skills and experience, as described above, to the role. While our Chief Executive Officer has primary responsibility for preparing the agendas for meetings of our board of directors, our chairperson has significant responsibilities, which are set forth in our bylaws, and include, in part: • Establishing the agenda for regular meetings of our board of directors; • Coordinating with the committee chairs regarding meeting agendas and information requirements, and presiding over portions of meetings of our board of directors at which the evaluation or compensation of the Chief Executive Officer is presented or discussed; • Coordinating the activities of the other directors, and performing such other duties as our board of directors may establish or delegate from time to time; and • Acting as principal liaison between the members of our board of directors and the Chief Executive Officer. The active involvement of our independent directors, combined with the qualifications and significant responsibilities of our chairperson and other directors, provide balance on our board of directors and promote strong, independent oversight of our management and affairs. Role of the Board of Directors in Risk Oversight One of the key functions of the board of directors is informed oversight of our risk management process. The board of directors does not anticipate having a standing risk management committee, but rather administers this oversight function directly through our board of directors as a whole, as well as through various standing committees of the board of directors that address risks inherent in their respective areas of oversight. In

-13- particular, the board of directors is responsible for monitoring and assessing strategic risk exposure and our Audit Committee has the responsibility to consider and discuss any major financial risk exposures and the steps our management will take to monitor and control such exposures, including guidelines and policies to govern the process by which risk assessment and management is undertaken. The Audit Committee monitors compliance with legal and regulatory requirements. The Compensation Committee assesses and monitors whether our compensation plans, policies and programs comply with applicable legal and regulatory requirements. Director Independence Our common stock is listed on Nasdaq. Under the listing standards of Nasdaq, independent directors must comprise a majority of a listed company’s board of directors, as affirmatively determined by the board of directors. In addition, the Nasdaq listing standards require that, subject to specified exceptions, each member of a listed company’s Audit, Compensation, and Nominating and Corporate Governance Committees be independent. Under the Nasdaq listing standards, a director will only qualify as an “independent director” if, in the opinion of that listed company’s board of directors, that director does not have a relationship that would interfere with the exercise of independent judgment in carrying out the responsibilities of a director. Audit committee members must also satisfy the additional independence criteria set forth in Rule 10A-3 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and the Nasdaq listing standards. Compensation Committee members must also satisfy the additional independence criteria set forth in Rule 10C- 1 under the Exchange Act and the Nasdaq. Our board of directors has undertaken a review of the independence of each of our directors. Based on information provided by each director concerning his or her background, employment and affiliations, our board of directors has determined that each of our current directors, Messrs. Harvey, Hickox, Rogerson, Stephanou, and Tripeny, and Mses. Cook and Fish, and our former directors, Mr. Drucker and Ms. Richardson who each served as a director during 2024, qualifies as “independent” as defined under the applicable Nasdaq rules. In making these determinations, our board of directors considered the current and prior relationships that each non-employee director has with the Company and all other facts and circumstances our board of directors deemed relevant in determining their independence, including the beneficial ownership of our capital stock by each non-employee director. Mr. Bissell is not deemed independent due to his position as our Chief Executive Officer, and our former director, Mr. Riley, who served as a director during 2024, was also not deemed independent due to his position as our Co-Chief Executive Officer. Family Relationships There are no family relationships between the board of directors and any of our executive officers. Board Meetings and Committees During our year ended December 31, 2024, our board of directors held six meetings (including regularly scheduled and special meetings). The Audit Committee met six times during the year ended December 31, 2024. The Compensation Committee met four times during the year ended December 31, 2024. The Nominating and Corporate Governance Committee met four times during the year ended December 31, 2024. Each director attended at least 75% of the aggregate of (i) the total number of meetings of our board of directors held during the period for which he or she has been a director and (ii) the total number of meetings held by all committees of our board of directors on which he or she served during the periods that he or she served. Committees of the Board of Directors The board of directors has established an Audit Committee, a Compensation Committee and a Nominating and Corporate Governance Committee. The composition and responsibilities of each of the committees of the

-14- board of directors are described below. Members serve on these committees until their resignation or until otherwise determined by the board of directors. The board of directors may establish other committees as it deems necessary or appropriate from time to time. Audit Committee The Audit Committee consists of John Hickox, Pia Heidenmark Cook, William J. Harvey, Craig A. Rogerson, and Jim Stephanou. Our board of directors has determined that each member of the Audit Committee satisfies the independence requirements under Nasdaq listing standards and Rule 10A-3(b)(1) of the Exchange Act. The chair of the Audit Committee is John Hickox. Our board of directors has determined that Messrs. Hickox and Rogerson are each an “audit committee financial expert” within the meaning of SEC regulations. Each member of the Audit Committee can read and understand fundamental financial statements in accordance with applicable requirements. In arriving at these determinations, our board of directors has examined each Audit Committee member’s scope of experience and the nature of their employment. The primary purpose of the Audit Committee is to discharge the responsibilities of the board of directors with respect to our corporate accounting and financial reporting processes, systems of internal control and financial statement audits, and to oversee our independent registered public accounting firm. Specific responsibilities of the Audit Committee include: • helping the board of directors oversee corporate accounting and financial reporting processes; • managing the selection, engagement, qualifications, independence and performance of a qualified firm to serve as the independent registered public accounting firm to audit our consolidated financial statements; • discussing the scope and results of the audit with the independent registered public accounting firm, and reviewing, with management and the independent accountants, our interim and year-end operating results; • developing procedures for employees to submit concerns anonymously about questionable accounting or audit matters; • reviewing related person transactions; • overseeing climate-related risks and opportunities and monitoring Origin’s compliance with Environmental Social Governance (“ESG”) and related legal and regulatory requirements impacting our accounting and financial reporting, including climate-related disclosures in our financial statements; • monitoring material risks relating to data privacy, technology and information security, including cybersecurity, threats and back-up of information systems and the Company’s processes for assessing, identifying, and managing such risks, as well as the Company’s internal controls and disclosure controls and procedures relating to cybersecurity incidents. • obtaining and reviewing a report by the independent registered public accounting firm at least annually that describes our internal quality control procedures, any material issues with such procedures, and any steps taken to deal with such issues when required by applicable law; and • approving or, as permitted, pre-approving, audit and permissible non-audit services to be performed by the independent registered public accounting firm.

-15- Our Audit Committee operates under a written charter that satisfies the applicable rules and regulations of the SEC and the Nasdaq listing standards. A copy of the charter of our Audit Committee is available on our website at www.originmaterials.com under “Investors – Governance – Governance Documents.” Compensation Committee Our Compensation Committee consists of Kathleen B. Fish, Craig A. Rogerson, and Jim Stephanou. The chair of the Compensation Committee is Ms. Fish. Our board of directors has determined that each member of the Compensation Committee is independent under the Nasdaq listing standards and a “non-employee director” as defined in Rule 16b-3 promulgated under the Exchange Act. The primary purpose of the Compensation Committee is to discharge the responsibilities of the board of directors in overseeing the compensation policies, plans and programs and to review and determine the compensation to be paid to executive officers, directors and other senior management, as appropriate. Specific responsibilities of the Compensation Committee will include: • reviewing and approving the compensation of the Chief Executive Officer, other executive officers and senior management; • reviewing and recommending to the board of directors the compensation of directors; • administering the equity incentive plans and other benefit programs; • reviewing, adopting, amending and terminating incentive compensation and equity plans, severance agreements, profit sharing plans, bonus plans, change-of-control protections and any other compensatory arrangements for the executive officers and other senior management; and • reviewing and establishing general policies relating to compensation and benefits of the employees, including the overall compensation philosophy. Our Compensation Committee operates under a written charter that satisfies the applicable rules and regulations of the SEC and the Nasdaq listing standards. A copy of the charter of our Compensation Committee is available on our website at www.originmaterials.com under “Investors – Governance – Governance Documents.” Compensation Committee Processes and Procedures The Compensation Committee meets periodically throughout the year to, among other responsibilities, manage and evaluate our executive compensation program, and generally determines, which may be subject to final board of directors approval, the principal components of compensation (base salary, performance bonus awards, and equity awards) for our executive officers on an annual basis. Typically, the Compensation Committee will meet at least twice annually and with greater frequency if necessary. The Compensation Committee meets from time to time in executive session. In addition, from time to time, various members of management and other employees as well as outside advisors or consultants may be invited by the Compensation Committee to make presentations, to provide financial or other background information or advice or to otherwise participate in Compensation Committee meetings. The Compensation Committee does not delegate authority to approve executive officer compensation. The Compensation Committee does not maintain a formal policy regarding the timing of granting equity awards to our executive officers and generally grants equity awards annually to executive officers , as well as at such other times as it determines appropriate, which typically includes when an executive officer is hired or promoted, and for retention or other purposes. The Compensation Committee typically grants equity awards on regularly scheduled dates that occur once a quarter. The Compensation Committee will continue to evaluate its equity grant practices as we continue to evolve and grow as a public company. The charter of the Compensation Committee grants the Compensation Committee full access to all books, records, facilities and personnel of the Company. Our Compensation Committee also works with and receives information and analyses from management, including within our legal, finance, and human resources

-16- departments, and our Chief Executive Officer, and considers such information and analyses in determining the structure and amount of compensation to be paid to our executive officers, including our named executive officers. Our Chief Executive Officer evaluates and provides to the Compensation Committee executive officer performance assessments and management’s recommendations and proposals regarding executive officer compensation programs and decisions affecting base salaries, equity compensation, and other compensation- related matters outside of the presence of any other named executive officers. However, our Compensation Committee retains the final authority to make all compensation decisions. While our Chief Executive Officer discusses his recommendations with the Compensation Committee, he may not participate in, or be present during, any deliberations or determinations of the Compensation Committee regarding his compensation. In addition, under the charter, the Compensation Committee has the authority to obtain, at the expense of the Company, advice and assistance from compensation consultants and internal and external legal, accounting or other advisors and other external resources that the Compensation Committee considers necessary or appropriate in the performance of its duties. The Compensation Committee has direct responsibility for the oversight of the work of any consultants or advisers engaged for the purpose of advising the Compensation Committee. In particular, the Compensation Committee has the sole authority to retain, in its sole discretion, compensation consultants to assist in its evaluation of executive and director compensation, including the authority to approve the consultant’s reasonable fees and other retention terms. Under the charter, the Compensation Committee may select, or receive advice from, a compensation consultant, legal counsel or other adviser to the Compensation Committee, other than in-house legal counsel and certain other types of advisers, only after taking into consideration six factors, prescribed by the SEC and Nasdaq, that bear upon the adviser’s independence; however, there is no requirement that any adviser be independent. During the year ended December 31, 2024, after taking into consideration the six factors prescribed by the SEC and Nasdaq described above, the Compensation Committee engaged Meridian Compensation Partners (“Meridian”) as its compensation consultant. The Compensation Committee requested that Meridian: • guide the Compensation Committee’s decision making with respect to executive compensation matters in light of the Company’s business strategy, pay philosophy, prevailing market practices, shareholder interests, and relevant regulatory mandates; • provide advice on the Company’s executive pay philosophy; • provide advice on the Company’s compensation peer group; • provide incentive plan design advice, for both annual and various long-term incentive vehicles and other compensation and benefit programs that meet Company objectives; • provide comprehensive competitive market studies as background against which the Compensation Committee can consider CEO and senior management base salary, annual bonus opportunity, long- term incentive awards, benefits, perquisites, and severance protections; • provide consulting and competitive market data on outside director compensation matters; and • apprise the Compensation Committee about emerging best practices and changes in the regulatory and corporate governance environment. As part of its engagement, Meridian developed and presented a comparative group of companies, performed analyses of competitive performance and compensation levels for that group, and presented recommendations to the Compensation Committee for its consideration. Following an active dialogue with Meridian, the Compensation Committee approved the recommendations.

-17- Nominating and Corporate Governance Committee Our Nominating and Corporate Governance Committee consists of William Harvey, Pia Heidenmark Cook, Kathleen B. Fish, and John Hickox. The chair of the Nominating and Corporate Governance Committee is William Harvey. Our board of directors has determined that each member of the Nominating and Corporate Governance Committee is independent under the Nasdaq listing standards. Specific responsibilities of the Nominating and Corporate Governance Committee include: • identifying and evaluating candidates, including the nomination of incumbent directors for re-election and nominees recommended by stockholders, to serve on the board of directors; • considering and making recommendations to the board of directors regarding the composition and chairmanship of the committees of the board of directors; • overseeing and advising the board of directors on our goals, strategies, and commitments related to sustainability and ESG matters other than those impacting our accounting and financial reporting, including climate risks and opportunities, human rights and human capital management, community and social impact, and diversity and inclusion; • developing and making recommendations to the board of directors regarding corporate governance guidelines and matters, including in relation to corporate social responsibility; and • overseeing periodic evaluations of the performance of the board of directors, including its individual directors and committees. Our Nominating and Corporate Governance Committee operates under a written charter that satisfies the applicable Nasdaq listing standards. A copy of the charter of our Nominating and Corporate Governance Committee is available on our website at www.originmaterials.com under “Investors – Governance – Governance Documents.” Board Diversity While we do not have a formal diversity policy in place, our Nominating and Corporate Governance Committee considers the diversity of our board of directors overall with respect to age, disability, gender identity or expression, ethnicity, military veteran status, national origin, race, religion, sexual orientation, and other backgrounds and experiences. Our Nominating and Corporate Governance Committee is committed to actively seeking out and will instruct any search firm it engages to identify, individuals who will contribute to the overall diversity of our board of directors to be included in the pool of candidates from which nominees to our board of directors are selected. Our board of directors monitors the mix of skills and experience of its directors to help ensure it has the necessary tools to perform its oversight function effectively. Our board of directors fully appreciates the value of a diversity of viewpoints, background and experiences as important to the selection of directors to enhance our board of director’s cognitive diversity and quality of dialogue in the boardroom. Considerations in Evaluating Director Nominees Our Nominating and Corporate Governance Committee uses a variety of methods for identifying and evaluating director nominees. In its evaluation of director candidates, our Nominating and Corporate Governance Committee will consider the current size and composition of our board of directors and the needs of our board of directors and the respective committees of our board of directors. Some of the qualifications that our Nominating and Corporate Governance Committee considers include, without limitation, issues of character, integrity, judgment, independence, area of expertise, corporate experience, length of service, potential conflicts of interest and other commitments. Nominees must also have the ability to offer advice and guidance to our Chief Executive Officer based on past experience in positions with a high degree of responsibility and be leaders in the companies or institutions with which they are affiliated. Director candidates must have sufficient time available in the judgment of our Nominating and Corporate Governance Committee to perform all board of

-18- director and committee responsibilities. Members of our board of directors are expected to prepare for, attend, and participate in all board of director and applicable committee meetings. Other than the foregoing, there are no stated minimum criteria for director nominees, although our Nominating and Corporate Governance Committee may also consider such other factors as it may deem, from time to time, are in our and our stockholders’ best interests. Our board of directors believes that it should be a diverse body, and our Nominating and Corporate Governance Committee considers a broad range of backgrounds and experiences. In making determinations regarding nominations of directors, our Nominating and Corporate Governance Committee may take into account the benefits of diverse viewpoints. Our Nominating and Corporate Governance Committee also considers these and other factors as it oversees the annual board of director and committee evaluations. After completing its review and evaluation of director candidates, our Nominating and Corporate Governance Committee recommends to our full board of directors the director nominees for selection. Stockholder Recommendations for Nominations to the Board of Directors Our Nominating and Corporate Governance Committee will consider candidates for director recommended by stockholders, so long as such recommendations comply with our amended and restated certificate of incorporation and amended and restated bylaws and applicable laws, rules and regulations, including those promulgated by the SEC. Our Nominating and Corporate Governance Committee will evaluate such recommendations in accordance with its charter, our amended and restated bylaws, our policies and procedures for director candidates, as well as the regular director nominee criteria described above. This process is designed to ensure that our board of directors includes members with diverse backgrounds, skills and experience, including appropriate financial and other expertise relevant to our business. Eligible stockholders wishing to recommend a candidate for nomination should contact our Secretary in writing. Such recommendations must include information about the candidate, a statement of support by the recommending stockholder, evidence of the recommending stockholder’s ownership of our common stock and a signed letter from the candidate confirming willingness to serve on our board of directors. Our Nominating and Corporate Governance Committee has discretion to decide which individuals to recommend for nomination as directors. Any nomination must comply with the requirements set forth in our bylaws and should be sent in writing to our Secretary at Origin Materials, Inc., 930 Riverside Parkway, Suite 10, West Sacramento, California 95605. To be timely for our 2026 annual meeting of stockholders, our Secretary must receive the nomination no earlier than January 6, 2026 and no later than February 5, 2026. In addition, stockholders who intend to solicit proxies in support of director nominees other than Origin’s nominees must also comply with the additional requirements of Rule 14a-19(b). Communications with the Board of Directors Interested parties wishing to communicate with our board of directors or with individual members of our board of directors may do so by writing to our board of directors or to the particular members of our board of directors, and mailing the correspondence to our Secretary at Origin Materials, Inc., 930 Riverside Parkway, Suite 10, West Sacramento, California 95605. Our Secretary, in consultation with appropriate members of our board of directors as necessary, will review all incoming communications and, if appropriate, such communications will be forwarded to the appropriate member or members of our board of directors, or if none is specified, to the Chairperson of our board of directors. Corporate Governance Guidelines and Code of Business Conduct and Ethics Our board of directors has adopted Corporate Governance Guidelines that address items such as the qualifications and responsibilities of our directors and director candidates and corporate governance policies and standards applicable to us in general. In addition, our board of directors has adopted a Code of Business

-19- Conduct and Ethics that applies to all of our employees, officers and directors, including our Chief Executive Officer, Chief Financial Officer, and other executive and senior financial officers. The full text of our Corporate Governance Guidelines and our Code of Business Conduct and Ethics is posted on the Corporate Governance portion of our website at www.originmaterials.com under “Investors – Governance – Governance Documents.” We will post amendments to our Code of Business Conduct and Ethics or waivers of our Code of Business Conduct and Ethics for directors and executive officers on the same website. Insider Trading Policy We have adopted an Insider Trading Policy governing the purchase, sale, and/or other dispositions of the Company’s securities by directors, officers and employees that is designed to promote compliance with insider trading laws, rules and regulations, as well as procedures designed to further the foregoing purposes. A copy of our insider trading policy is filed as an exhibit to our Annual Report on Form 10-K for our fiscal year ended December 31, 2024. In addition, it is the Company’s intent to comply with applicable laws and regulations relating to insider trading. Anti-Hedging and Pledging Policies Our board of directors has adopted an Insider Trading Policy governing the purchase, sale, and/or other dispositions of the Company’s securities by directors, officers and employees, that are reasonably designed to promote compliance with insider trading laws, rules and regulations, and listing standards applicable to the Company. Under our Insider Trading Policy, directors and executive officers, as well as other employees, are prohibited from engaging in the following activities with respect to the Company’s common stock: • Hedging their interest in Company shares by selling short or trading or purchasing “put” or “call” options on our common stock or engaging in similar transactions; and • Pledging any shares of our common stock without prior clearance from our Corporate Compliance Officer as outlined in our Insider Trading Policy. As of the date of this Proxy Statement, no shares of Company common stock were pledged by any director or executive officer. Director Compensation We have a non-employee director compensation policy pursuant to which our unaffiliated, non-employee directors are eligible to receive equity awards and annual cash compensation for service on our board of directors and committees of our board of directors. In light of considerations related to the Company’s then- current stock price, our board of directors amended the policy in May 2024 to reduce the grant date fair value of certain equity awards that non-employee directors were eligible to receive for calendar year 2024, as described below, with the grant date fair value of such equity awards automatically returning to the levels in effect immediately prior to such amendment for calendar years after 2024. Pursuant to our non-employee director compensation policy, each non-employee director is entitled to a $50,000 annual cash retainer. The members of the Audit Committee, Compensation Committee, and Nominating and Corporate Governance Committee are also entitled to an annual cash retainer of $10,000, $5,000, and $5,000, respectively, other than the chair of each such committee, who is instead entitled to an annual cash retainer of $20,000, $15,000, and $15,000, respectively. Each non-employee director may elect to forego receiving payment of all (but not less than all) of the foregoing cash compensation and instead receive fully vested restricted stock units with an equivalent grant date fair value. In addition to the cash compensation, each non-employee director who is first elected or appointed to the board of directors will also receive a one-time initial grant of restricted stock units with a grant date fair value of $150,000, to vest in three equal installments on the first, second and third anniversary of the grant date. Any non-employee director who is first elected or appointed to the board of directors on a date other than an annual stockholder meeting of the Company will be granted an additional number of restricted stock units with a grant date fair value of $130,000 (reduced to $85,000 for calendar year 2024 only), or, in the case of the chair of the

-20- board of directors, $205,000 (reduced to $160,000 for calendar year 2024 only), prorated to reflect the non- employee director’s partial service between the last annual stockholder meeting preceding the non-employee director’s election or appointment to the board of directors and the next annual stockholder meeting, and to vest in full on the earlier of the first anniversary of the grant date and the date of the Company’s next annual stockholder meeting. Each non-employee director continuing to serve as a non-employee director following a stockholder meeting occurring after June 25, 2021 will also receive an annual grant of restricted stock units with a grant date fair value of $130,000 (reduced to $85,000 for calendar year 2024 only), or, in the case of the chair of the board of directors, $205,000 (reduced to $160,000 for calendar year 2024 only). Each annual award will vest on the earlier of the first anniversary of the grant date and the Company’s next annual stockholder meeting.

-22- PROPOSAL NO. 1 ELECTION OF DIRECTORS Our board of directors is currently composed of eight members. In accordance with our amended and restated certificate of incorporation, our board of directors is divided into three staggered classes of directors. At the Annual Meeting, three Class I directors will be elected for a one-year term to succeed the three Class I directors whose term is then expiring. It is the Company’s policy to invite directors and nominees for director to attend the Annual Meeting, including virtually if applicable. All of the directors attended the 2024 Annual Meeting of Stockholders. Each director’s term continues until the election and qualification of his or her successor, or such director’s earlier death, resignation, or removal. Any increase or decrease in the number of directors will be distributed among the three classes so that, as nearly as possible, each class will consist of one-third of our directors. This classification of our board of directors may have the effect of delaying or preventing changes in control of our company, though the classification of our board ends with the next annual meeting of our stockholders, after which each of our directors will stand for election annually for a one-year term. Nominees Our Nominating and Corporate Governance Committee has unanimously nominated, and our board of directors has approved, Pia Heidenmark Cook, William J. Harvey, and Craig A. Rogerson as nominees for election as Class I directors at the Annual Meeting to hold office until the Company’s 2026 Annual Meeting of Stockholders and until a successor is elected and qualified or, if sooner, until the director’s death, resignation or removal. Ms. Cook joined our board of directors in June 2021. Mr. Harvey served as a member of the board of directors of Legacy Origin from June 2017 until the closing of the Business Combination in June 2021, and has served as a member of our board of directors since the closing of the Business Combination in June 2021. Mr. Rogerson joined our board of directors beginning on May 1, 2023. If elected, Ms. Cook and Messrs. Harvey and Rogerson will serve as Class I directors until our 2026 annual meeting of stockholders. Each of the nominees is currently a director of our company. For information concerning the nominees, please see the section titled “Board of Directors and Corporate Governance.” If you are a stockholder of record and you sign your proxy card or vote by telephone or over the Internet but do not give instructions with respect to the voting of directors, your shares will be voted “FOR” the election of Ms. Cook and Messrs. Harvey and Rogerson. If any nominee becomes unavailable for election as a result of an unexpected occurrence, our board of directors may designate a substitute nominee, in which event the persons named in the enclosed proxy will vote for the election of such substitute nominee, unless our board of directors chooses to reduce the number of directors serving on our board of directors. Each person nominated for election has consented to being named as a nominee in this Proxy Statement and has agreed to serve if elected. We have no reason to believe that any nominee will be unable to serve. Vote Required For the election of directors, the three nominees receiving the most “FOR” votes from the holders of shares present in person or virtually or represented by proxy and entitled to vote generally on the election of directors will be elected. Only votes “FOR” will affect the outcome. THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” EACH OF THE NOMINEES NAMED ABOVE.

-23- PROPOSAL NO. 2 RATIFICATION OF APPOINTMENT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM Our Audit Committee has appointed Deloitte & Touche LLP (“Deloitte”), independent registered public accountants, to audit our consolidated financial statements for our year ended December 31, 2025. During our year ended December 31, 2024, Deloitte & Touche LLP (“Deloitte”) served as our independent registered public accounting firm following the dismissal of Grant Thornton LLP in March 2023. Notwithstanding the appointment of Deloitte and even if our stockholders ratify the appointment, our Audit Committee, in its discretion, may appoint another independent registered public accounting firm at any time during our fiscal year if our Audit Committee believes that such a change would be in the best interests of the Company and our stockholders. At the Annual Meeting, our stockholders are being asked to ratify the appointment of Deloitte as our independent registered public accounting firm for our fiscal year ended December 31, 2025. Our Audit Committee is submitting the appointment of Deloitte to our stockholders because we value our stockholders’ views on our independent registered public accounting firm and as a matter of good corporate governance. Representatives of Deloitte will be present at the Annual Meeting, and they will have an opportunity to make a statement and will be available to respond to appropriate questions from our stockholders. If our stockholders do not ratify the appointment of Deloitte, our board of directors may reconsider the appointment. Change in Independent Registered Public Accounting Firm Dismissal of Grant Thornton LLP and Engagement of Deloitte & Touche LLP The Audit Committee conducted an evaluation process to determine the Company’s independent registered public accounting firm for the fiscal year ended December 31, 2023. The Audit Committee, with the assistance of our management, evaluated several independent registered public accounting firms as part of this process, reviewing the qualifications, the independence and, if a firm was deemed to be qualified and independent to warrant further evaluation, the range of fees associated with their services. On March 6, 2023, the Audit Committee approved the dismissal of Grant Thornton as our independent registered public accounting firm. Grant Thornton’s report on our consolidated financial statements as of and for the year ended December 31, 2022, which was included in our Annual Reports on Form 10-K for the fiscal years ended December 31, 2023 and 2022, and report on our internal control over financial reporting for the year ended December 31, 2022, which was included in our Annual Report on Form 10-K for the fiscal year ended December 31, 2022, did not contain an adverse opinion or disclaimer of opinion and were not qualified or modified as to uncertainty, audit scope or accounting principles. During the fiscal years ended December 31, 2023 and 2022, there were: (i) no disagreements within the meaning of Item 304(a)(1)(iv) of Regulation S-K between us and Grant Thornton on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which, if not resolved to Grant Thornton’s satisfaction, would have caused Grant Thornton to make reference thereto in Grant Thornton’s reports; and (ii) no “reportable events” within the meaning of Item 304(a)(1)(v) of Regulation S-K, except for the material weakness in our internal control over financial reporting previously reported in Part II, Item 9A “Controls and Procedures” in our Annual Report on Form 10-K for the year ended December 31, 2022. During the audit of our consolidated financial statements for the fiscal years ended December 31, 2019 and December 31, 2020, during the course of preparing for our business combination, and during the second quarter 2021 and third quarter 2021 interim reviews, we identified a material weakness in our internal controls over financial reporting. As discussed in our Annual Report on Form 10-K for the fiscal year ended December 31, 2021, we concluded that the identified material weakness has been remediated.

-24- We previously provided Grant Thornton with a copy of the disclosures regarding the dismissal reproduced in this Proxy Statement and received a letter from Grant Thornton addressed to the SEC stating that they agree with the above statements. This letter was filed as an exhibit to our Current Report on Form 8-K filed with the SEC on March 9, 2023. On March 6, 2023, the Audit Committee approved the appointment of Deloitte as our independent registered public accounting firm for the fiscal year ended December 31, 2023 based on an extensive review process considering, among other things, Deloitte’s ability to understand our business as its grows in scale and complexity. Preceding the engagement of Deloitte, neither we nor anyone acting on our behalf consulted with Deloitte regarding either: (i) the application of accounting principles to a specified transaction, either completed or proposed; or the type of audit opinion that might be rendered on our financial statements, and neither a written report nor oral advice was provided to us that Deloitte concluded was an important factor considered by us in reaching a decision as to the accounting, auditing or financial reporting issue; or (ii) any matter that was either the subject of a disagreement or a reportable event. Principal Accounting Fees and Services The following tables set forth the aggregate fees for professional audit services and other services rendered by Deloitte and Grant Thornton for the years ended December 31, 2024 and 2023. Deloitte 2024 2023 Audit Fees(1) $ 979,000 $ 1,007,000 Audit-Related Fees — — Tax Fees — — All Other Fees (2) 2,000 64,000 Total Fees $ 981,000 $ 1,071,000 Grant Thornton 2023 Audit Fees(1) $ 175,000 Audit-Related Fees — Tax Fees — All Other Fees — Total Fees $ 175,000

-25- ______________ (1) “Audit Fees” consist of fees billed for professional services rendered in connection with the audit of our consolidated financial statements, reviews of our quarterly consolidated financial statements and related accounting consultations and services that are normally provided by the independent registered public accountants in connection with statutory and regulatory filings or engagements for those fiscal years. (2) “All Other Fees” consists of fees billed for consulting services rendered in connection with tax incentives related to manufacturing site selection activities in 2023. It also includes product and subscription services. In our year ended December 31, 2024, there were no other professional services provided by Deloitte that would have required our Audit Committee to consider their compatibility with maintaining the independence of Deloitte. Audit Committee Policy on Pre-Approval of Audit and Permissible Non-Audit Services of Independent Registered Public Accounting Firm The Audit Committee has adopted an Audit Committee Pre-Approval Policy for Services of the Independent Registered Accounting Firm, or the Policy, which sets forth the procedures and the conditions pursuant to which services proposed to be performed by the independent registered public accounting firm may be pre-approved. Under the Policy, all audit, audit-related and tax services to be provided by the independent registered public accounting firm are subject to pre-approval by the Audit Committee. In addition, the Policy authorizes the chairperson of the Audit Committee to pre-approve services not prohibited by the Policy to be performed by our independent registered public accounting firm and associated fees up to $120,000, provided that the chairperson is required to report any decision to pre-approve such audit- related or non-audit services and fees to the full Audit Committee at its next regular meeting. All audit-related and non-audit related services performed by our independent registered public accounting firm in 2024 were pre-approved. Vote Required The ratification of the appointment of Deloitte as our independent registered public accounting firm requires the affirmative vote of a majority of the shares of our common stock present in person or by proxy at the Annual Meeting and entitled to vote on the matter. Abstentions will have the effect of a vote AGAINST the proposal and broker non-votes will have no effect. THE BOARD OF DIRECTORS RECOMMENDS A VOTE “FOR” THE RATIFICATION OF THE APPOINTMENT OF DELOITTE & TOUCHE LLP. REPORT OF THE AUDIT COMMITTEE The Audit Committee currently consists of John Hickox, Pia Heidenmark Cook, William Harvey, Craig Rogerson, and Jim Stephanou, all of whom are non-management directors. The Audit Committee is a committee of the board of directors comprised solely of independent directors as required by the Nasdaq listing standards and rules and regulations of the SEC. The Audit Committee operates under a written charter approved by the board of directors, which is available on the company’s website at www.originmaterials.com under “Investors – Corporate Governance”. The composition of the Audit Committee, the attributes of its members and the responsibilities of the Audit Committee, as reflected in its charter, are intended to be in accordance with applicable requirements for corporate audit committees. The Audit Committee reviews and assesses the adequacy of its charter and the audit committee’s performance on an annual basis. The Audit Committee has reviewed and discussed the audited financial statements for the year ended December 31, 2024 with management. The Audit Committee has discussed with the independent registered public accounting firm the matters required to be discussed by the applicable requirements of the Public Company Accounting Oversight Board (“PCAOB”) and SEC. The Audit Committee has received the written

-26- disclosures and the letter from the independent registered public accounting firm required by applicable requirements of the PCAOB regarding the independent accountants’ communications with the Audit Committee concerning independence and has discussed with the independent registered public accounting firm the accounting firm’s independence. Based on the foregoing, the Audit Committee recommended to the board of directors that the audited financial statements be included in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024 for filing with the SEC. Respectfully submitted by the members of the Audit Committee of the board of directors: John Hickox (Chair) Pia Heidenmark Cook William Harvey Craig Rogerson Jim Stephanou This report of the Audit Committee is not “soliciting material,” is not deemed “filed” with the SEC and is not to be incorporated by reference in any of our filings under the Securities Act of 1933, as amended, or the Exchange Act, whether made before or after the date hereof and irrespective of any general incorporation language in any such filing, except to the extent specifically incorporated by reference herein.

-27- PROPOSAL NO. 3 ADVISORY NON-BINDING VOTE TO APPROVE THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS Under Section 14A of the Exchange Act, our stockholders are entitled to vote to approve, on a non- binding advisory basis, the compensation of our named executive officers as disclosed in this Proxy Statement in accordance with SEC rules. As described in detail under the heading “Executive Compensation,” our executive compensation program is designed to drive and reward performance and align the compensation of our named executive officers with the long-term interests of our stockholders. Please read the compensation tables and narrative disclosure that follow under the section titled “Executive Compensation” for information about our executive compensation program. This proposal, commonly known as a “say-on-pay” proposal, gives our stockholders the opportunity to express their views on our named executive officers’ compensation as a whole. This vote is not intended to address any specific element of compensation, but rather the overall compensation of our named executive officers and the philosophy, policies, and practices described in this Proxy Statement. Our board and our Compensation Committee believe that these policies and practices are effective in implementing our compensation philosophy and achieving our compensation program goals. At the 2022 annual meeting of stockholders, our stockholders indicated, by a non-binding advisory vote, that they agreed with our Board’s recommendation that we solicit a non-binding advisory vote on the compensation of our named executive officers, commonly referred to as “say-on-pay,” every year. Our Board has adopted a policy that is consistent with that preference and, accordingly, we are holding a say-on-pay vote at this annual meeting. A “say-on-frequency” vote is required at least every six years and, as such, our next say- on-frequency vote will be no later than 2028. We are asking our stockholders to vote “FOR” the following resolution: “RESOLVED, that Origin’s stockholders hereby approve, on an advisory non-binding basis, the compensation paid to Origin’s named executive officers, as disclosed in the company’s Proxy Statement for the 2025 Annual Meeting of Stockholders, pursuant to the compensation disclosure rules of the SEC, including in the compensation tables and the narrative discussions that accompany the compensation tables under the section titled ‘Executive Compensation.’” Vote Required The approval of this advisory non-binding proposal requires the affirmative vote of a majority of the voting power of the shares of our common stock present in person or by proxy at the Annual Meeting and entitled to vote on the matter. Abstentions will be considered votes present and entitled to vote on this proposal, and thus, will have the same effect as a vote “AGAINST.” Broker non-votes will have no effect on the outcome of this proposal. As an advisory vote, the outcome of the vote on this proposal is not binding. However, our management team, our board, and our Compensation Committee, which is responsible for designing and administering our executive compensation program, value the opinions expressed by our stockholders, and will consider the outcome of this vote when making future executive compensation decisions. OUR BOARD RECOMMENDS THAT YOU VOTE “FOR” THE APPROVAL, ON AN ADVISORY NON-BINDING BASIS, OF THE COMPENSATION OF OUR NAMED EXECUTIVE OFFICERS, AS DISCLOSED IN THIS PROXY STATEMENT.

Executive Compensation Our Compensation Committee oversees the Company’s compensation and benefit plans, policies and programs, and administration of Company equity plans, and reviews and determines the compensation of the Company’s executive officers, directors, and senior management, as appropriate. Other Features of Our Compensation Program Employment Offer Letters Each of our named executive officers is an at-will employee other than Rich Riley, who ceased being an employee on December 31, 2024, and is currently an advisor to the Company, as described in more detail below under the section titled—“Separation and Advisory Agreement with Rich Riley.” Each named executive officer other than John Bissell, who is a co-founder and Chief Executive Officer of the Company, and other than Mr. Riley, who resigned as Co-Chief Executive Officer as of December 31, 2024 , is currently party to an offer letter setting forth his terms of employment as of the date of the offer letter, including title, initial salary, grant of initial equity award(s), eligibility to participate in our health and welfare benefit plans, and, for Mr. Riley only, his appointment to our board of directors. The base salaries and any equity awards of our named executive officers are reviewed annually by the Compensation Committee, except for Mr. Riley who resigned as Co-Chief Executive Officer as of December 31, 2024. Please see the section titled “Outstanding Equity Awards as of December 31, 2024” for additional information regarding the equity awards held by our named executive officers.

Rich Riley Rich Riley was the Company’s Co-Chief Executive Officer and a party to an offer letter dated October 28, 2020 prior to resigning effective December 31, 2024. Prior to resigning, Mr. Riley’s base salary was equal to $400,000. In connection with his resignation, Mr. Riley entered into a separation and advisory agreement with the Company, as described in more detail below under the section titled—“Separation and Advisory Agreement with Rich Riley.” Matt Plavan Matt Plavan is the Company’s Chief Financial Officer and Chief Operating Officer, and is party to an offer letter dated September 25, 2023.

Mr. Lee’s current annual base salary is equal to $290,000. Separation and Advisory Agreement with Rich Riley In connection with his resignation as Co-Chief Executive Officer, the Company and Mr. Riley entered into a separation and advisory agreement in December 2024, pursuant to which the Company will provide Mr. Riley with (i) cash severance equal to $600,000 (the equivalent of 18 months of base salary), paid on the Company’s normal payroll cycle over 18 months, and (ii) up to 18 months of health insurance premium payments. Pursuant to this agreement, Mr. Riley will provide the Company with advisory services from December 31, 2024 through January 2, 2026, during which period Mr. Riley’s equity awards will continue to vest. The severance benefits described above and the advisor arrangement, including continued vesting of Mr. Riley’s equity awards, are conditioned on Mr. Riley timely signing and not revoking a general release of claims in favor of the Company and satisfying certain other conditions. Clawback In October 2023, our Compensation Committee adopted an incentive compensation recoupment policy that complies with Nasdaq’s listing standards and SEC rules. The policy provides that, in the event we are required to prepare an accounting restatement, we will be required to recover incentive-based compensation received by any current or former executive officer based wholly or in part upon the attainment of a financial reporting measure that was erroneously awarded during the period of time specified in the recoupment policy. In addition, as a public company subject to the provisions of Section 304 of the Sarbanes-Oxley Act of 2002, if we are required as a result of misconduct to restate our financial results due to our material noncompliance with any financial reporting requirements under the federal securities laws, our Chief Executive Officer and Chief Financial Officer may be legally required to reimburse us for any bonus or other incentive-based or equity- based compensation they receive. Policies and Practices Related to the Grant of Certain Equity Awards Close in Time to the Release of Material Nonpublic Information The Company does not grant stock options, stock appreciation rights, or similar instruments with option- like features. Accordingly, the Company has no policies or practices to disclose pursuant to Item 402(x)(1) of Regulation S-K.

-32- Potential Payments upon Severance and Change in Control Rich Riley – Former Co- Chief Executive Officer Rich Riley, our former Co-Chief Executive Officer, is eligible to receive the severance benefits described above under the section titled—“Separation and Advisory Agreement with Rich Riley.” Matt Plavan – Chief Financial Officer and Chief Operating Officer Our Chief Financial Officer and Chief Operating Officer, Matt Plavan, received a one-time initial “Welcome” grant of 1,101,983 shares of RSUs under the Company’s 2021 Equity Incentive Plan (the “2021 Plan”), and pursuant to the Company’s then-current restricted stock agreement, and an “Annual” grant of 241,105 shares of RSUs. If Mr. Plavan is terminated for any reason except “Cause” (as defined by the 2021 Plan), he will become vested in shares equal to six months of his base salary and benefits coverage costs. If there is a “change-in-control” (as defined by the 2021 Plan), and Mr. Plavan is terminated for any reason except “Cause,” then the unvested portion of his Welcome grant will be deemed to have vested immediately prior to his termination date. In addition, in the event of a corporate transaction (as defined in the 2021 Plan), any equity awards granted to our named executive officers under our 2021 Plan, unless otherwise provided in the named executive officer’s award agreement or other written agreement with us, that are outstanding and not assumed, continued or substituted for by any surviving or acquiring entity will be accelerated in full (or, for performance-based awards with multiple vesting levels depending on the level of performance, vesting will accelerate at 100% of the target level) effective as of a date prior to the effective time of the corporate transaction (contingent upon the effectiveness of the corporate transaction), subject to the executive officers’ continuous service with the Company through the effective time of the corporate transaction. Health and Welfare Benefits Our named executive officers are eligible to participate in all of our benefit plans, including our medical, dental, vision, life, disability and accidental death and dismemberment insurance plans, and 401(k) plan, in each case generally on the same basis as other employees. We do not offer a pension plan or other qualified or non- qualified defined benefit or deferred compensation plans. Our Compensation Committee may elect to adopt such plans in the future if it determines that doing so is in our best interests. Perquisites We typically do not offer perquisites or personal benefits to our named executive officers other than telephone and internet stipends generally available to other employees. We may from time to time provide reasonable relocation or signing bonuses to our named executive officers as the Compensation Committee determines appropriate to assist such individuals to commence employment with us. Tax and Accounting Considerations As a general matter, the Compensation Committee reviews and consider, among other factors, the various tax and accounting implications of compensation programs we utilize.

Rule 10b5-1 Sales Plans Our directors and executive officers may adopt written plans, known as Rule 10b5-1 plans, in which they will contract with a broker to buy or sell shares of common stock on a periodic basis. Under a Rule 10b5- 1 plan, a broker executes trades pursuant to parameters established by the director or executive officer when entering into the plan, without further direction from them. The director or executive officer may amend a Rule 10b5-1 plan in some circumstances and may terminate a plan at any time. Our directors and executive officers also may buy or sell additional shares outside of a Rule 10b5-1 plan when they are not in possession of material nonpublic information, subject to compliance with the terms of our insider trading policy.

-34- Tabular Disclosure of Pay Versus Performance In accordance with Item 402(v) of Regulation S-K, we are providing the following disclosure regarding executive compensation for our principal executive officers (“PEOs”) and non-PEO named executive officers (“Non-PEO NEOs”) and Company performance for the fiscal years listed below. The Compensation Committee did not consider the pay versus performance disclosure below in making its pay decisions for any of the years shown. The table below presents the pay versus performance information for the named executive officers which have been calculated in a manner consistent with Item 402(v) of Regulation S-K.Use of the term “compensation actually paid” (or “CAP”) is required by the Securities and Exchange Commission’s (“SEC”) rules and as a result of the calculation methodology required by the SEC, such amounts differ from compensation actually received by the individuals for the fiscal years listed below.

For the portion of CAP that is based on year-end stock prices, the following prices were used: for 2024 $1.28, 2023 $0.84 and 2022 $4.61. (1) In the Company’s definitive proxy statement filed on March 22, 2024, the Company incorrectly disclosed that for fiscal year 2023 the Average Compensation Actually Paid to Non-PEO NEOs was $494,410,

HOUSEHOLDING OF ANNUAL MEETING MATERIALS The SEC has adopted rules that permit companies and intermediaries (such as banks and brokers) to satisfy the delivery requirements for proxy materials with respect to two or more stockholders sharing the same address by delivering a single copy of the Proxy Statement, Annual Report on Form 10-K or Notice of Internet Availability of Proxy Materials, as applicable, addressed to those stockholders. This process, which is commonly referred to as “householding,” potentially means extra convenience for stockholders and cost savings for companies. This year, a number of brokers with account holders who are our stockholders will be householding our proxy materials. A single Notice of Internet Availability of Proxy Materials will be delivered

-41- to multiple stockholders sharing an address unless contrary instructions have been received from the impacted stockholders. Once you have received notice from us (if you are a stockholder of record) or from your broker (if you are a beneficial owner) that we or they will be “householding” communications to your address, “householding” will continue until you are notified otherwise or until you revoke your consent. Upon oral or written request, we will deliver promptly a separate copy of the proxy materials to a stockholder at a shared address to which a single copy of proxy materials was delivered. If, at any time, you no longer wish to participate in “householding” and would prefer to receive separate proxy materials, including the Notice, or if you currently receive multiple copies and would like to request “householding” of your communications, please notify your broker or us. Direct your written request to us to Origin Materials, Inc., Attention: Investor Relations, 930 Riverside Parkway, Suite 10, West Sacramento, California 95605 or by telephone at (916) 231- 9329. In the event a stockholder that received multiple copies would like to receive only one copy for such stockholder’s household, such stockholder should contact their bank, broker, or other nominee record holder, or contact us at the above address or phone number.

If any of the following risks actually occur, our stock price, business, operating results and financial condition could be materially adversely affected. For more detailed descriptions of each risk factor, see item 1A titled “Risk Factors.” • We are an early stage company with a history of losses and our future profitability is uncertain. • Our business plan assumes we can secure substantial additional project financing and/or government incentives, which may be unavailable on favorable terms, if at all. • We have not yet produced any of our products in large commercial quantities. • Construction of manufacturing lines for production of our PET closures, or of additional plants beyond Origin 1, may not be completed in a timely-manner or completed in a cost-effective manner or at all. Any delays in or failure to finance and complete the construction of manufacturing facilities could severely impact the implementation and commercialization of our PET closures and furanics technologies. • We currently rely on, and plan to rely on, a limited number of manufacturing facilities to meet near-term customer demand for our PET closures and for our future intermediate chemical sales. • We rely on a limited number of customers for a significant portion of our near-term revenue. • Our industry is highly competitive, and we may lose market share to producers of products that can be substituted for our products, which may have an adverse effect on our results of operations and financial condition. • Increases or fluctuations in the costs of our raw materials may adversely affect our cost structure. • We are dependent on third-party suppliers and service providers, some of which are sole source suppliers, who may fail, and in some cases have failed, to deliver raw materials or equipment or fail to supply needed services at all or according to schedules, prices, quality, and volumes acceptable to us, or we may be unable to manage these supplies effectively. • We have entered into and may in the future enter into collaborations, strategic alliances, or licensing arrangements, which expose us and our intellectual property to competitive risks and limitations associated with third-party collaborations and that may not produce the benefits we anticipate. • Compliance with extensive environmental, health, and safety laws could require material expenditures, changes in our operations or site remediation. • Our business relies on proprietary information and other intellectual property, and our failure to protect our intellectual property rights could harm our competitive advantages with respect to the use, manufacturing, sale or other commercialization of our processes, technologies and products, which may have an adverse effect on our results of operations and financial condition. • We may face patent infringement and other intellectual property claims that could be costly to defend, result in injunctions and significant damage awards or other costs (including indemnification of third

4 parties or costly licensing arrangements, if licenses are available at all) and limit our ability to use certain key technologies in the future or require development of non-infringing products or technologies, which may cause us to incur significant unexpected costs, prevent us from commercializing our products and otherwise harm our business. • We rely on trade secrets to protect our technology, and our failure to maintain trade secret protection could limit our ability to compete. • Our management team has relatively limited experience operating a public company. • We previously identified a material weakness in our internal control over financial reporting that we have concluded has been remediated. However, we may identify additional material weaknesses in the future or fail to maintain effective internal control over financial reporting, which may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations.

5 Part I Item 1. Business Overview Origin is a technology company with a mission to enable the world’s transition to sustainable materials. Our innovations include PET closures for an estimated global closures market opportunity of greater than $65 billion. Our PET closures enable fully-recyclable PET beverage containers and reduce waste through light-weighting, while providing enhanced performance such as greater oxygen and CO2 barrier properties that can increase shelf- life. Our furanics technologies include our furanics platform for transforming carbon into sustainable materials for a wide range of end products capable of addressing an estimated $1 trillion market opportunity, including food and beverage packaging, clothing, textiles, plastics, car parts, carpeting, tires, adhesives, soil amendments, and fuels. Our Products and Technologies PET Closures Technology Platform Our PET closures and technologies for producing them reflect our mission to enable the world's transition to sustainable materials, as well as our polymer expertise and platform development capability. We are going to market with what we believe is the first commercially viable PET closure. We anticipate that our PET closure solutions can be transformative for packaging by designing for recycling circularity and improving the performance and sustainability of packaging. Our product candidates for markets include the PCO 1881 compliant PET closure and a tethered PET closure designed to comply with European cap tethering mandates and keep caps connected to bottles.

6 Our first Origin CapFormer System, a PET closure manufacturing system, successfully completed its Factory Acceptance Test (“FAT”), which involves a series of tests performed on the system to ensure that the system meets the requirements and functions as intended, in September 2024. Since September 2024, our CapFormer System has produced caps for commercial qualification and has been delivered to our operations and manufacturing center in Reed City, Michigan, where it commenced commercial production in February 2025. We anticipate bringing online additional CapFormer Systems as part of our scale-up strategy. In February 2025, we announced that three new CapFormer lines were nearing completion, with eight total lines expected by the end of December 2025. Furanics Technologies Including Biomass Conversion Platform In addition to our closures business, we have developed a number of technologies related to furanics, a class of chemicals with properties enabling the production of widespread and valuable materials, like plastics. These include our proprietary technology for transforming biomass, or plant-based carbon, into versatile intermediate chemicals. These intermediate chemicals include chloromethylfurfural (“CMF”) and hydrothermal carbon (“HTC”), which we collectively refer to as Furanic Intermediates, as well as oils and extractives and other co- products. We believe that products made using our furanics technology at sufficient scale and maturity can compete directly with petroleum-derived products on both performance and price while being sustainable and lowering the carbon footprint. CMF is a chemically flexible intermediate that can be converted into a variety of products, including numerous commodity and specialty chemicals. Applications include paraxylene (“PX”), which is a precursor to purified terephthalic acid (“PTA”) and subsequently PET; furandicarboxylic acid (“FDCA”), which can be converted into polyethylene furanoate (“PEF”). CMF target markets include food and beverage packaging, apparel, carpet fibers, adhesives, coatings and plasticizers. HTC is a diverse, high-potential material. Current applications of our HTC include a drop-in, energy-dense solid fuel. Our HTC product development pipeline includes carbon black replacement for tires, foams and dyes, paint and coating applications, and agriculture and soil products. Further, we believe oils and extractives could be used to produce cellulose-derived, low carbon intensity biofuels for transportation and marine fuel, industrial applications, and heat and power generation. We continue to perform development work related to our furanics technology. Origin 1, our plant in Sarnia, Ontario, Canada, is currently operating “on demand” with reduced staffing, while preserving our ability to generate product at small volumes sufficient to explore scale-up with strategic partners. This decision was made in alignment with our near-term focus on PET closures as our path to profitability and our asset light strategy for our future plant to further scale up furanics technology. For our future plant, we have explored a variety of plant

7 designs and conducted testing and optimization of various feedstocks to generate data that could influence our scale-up strategy. Market Opportunity We believe that our near-term and long-term addressable markets together exceed $1.0 trillion. • Approximately $65 billion immediate opportunity. We expect our PET closures to begin to address a greater than $65 billion global closures market. • Approximately $1 trillion+ long-term market opportunity. Our furanics technology produces versatile chemical “building blocks” that we anticipate, in the long term, can be converted into products to replace a broad range of chemicals and materials representing an addressable market that we believe is more than $1 trillion. These markets include polyesters for textiles, resin for packaging, solid fuels, activated carbon, carbon black for tires and polymer fillers, paints, coatings, soil additives, advanced polyesters, epoxies, plasticizers, polyurethanes, elastomers, emulsions and solvents. Our Addressable Markets Within the estimated $65 billion closures market, we believe there is strong and growing demand for solutions offering superior performance and sustainability characteristics, We believe there is particularly strong demand for those products that are designed for circularity, thus enabling the re-use and recycling of materials, as opposed to waste and downcycling. We designed our PET closures to outperform today’s incumbent HDPE and polypropylene caps in ways that can improve product shelf life without relying on custom polymers, which can compromise the purity of the recycling system. Our technology enables the lightest cap for a wide variety of containers, reducing plastic waste and improving sustainability. We expect to make PET closures in a wide variety of formats for not only beverage containers but food containers and others as well. Our furanics technologies and biomass conversion platform address the chemicals market broadly due to the flexible chemistry, low carbon footprint, and competitive unit economics of our intermediates. According to the International Energy Agency, the chemical sector is the largest industrial consumer of both oil and gas. Currently, organic chemicals are predominantly derived from fossil sources such as petroleum. These chemicals are used to produce a wide array of materials from paints to plastics, space suits to solar panels, and from medicines to electronics. Our furanics technology can enable companies to lower their overall CO2 emissions and meet their emissions reduction commitments by substituting decarbonizing Furanic Intermediates and their derivatives for all or a portion of the fossil-based content of materials in their supply chains. Competitive Landscape In the closures market, we anticipate potential competition from traditional HDPE and polypropylene cap producers and other companies who could develop and launch PET caps. Following the trend of lightweighting, competitors may continue to develop lighter weight caps. We expect our caps to be among the lightest of their kind; however, if alternative caps continue to become lighter, this could reduce our currently expected advantage with respect to this trait. We may also face competition from manufacturers of non-plastic containers. Apart from competition, we believe there are opportunities for cooperation with incumbent cap producers who could help commercialize and increase adoption of our PET closures.

8 For our furanics technologies and biomass conversion platform, we expect our products to compete with traditional, petroleum-based materials currently used in our target markets, as well as compete with alternatives to these materials that both established and new companies seek to produce. We expect to compete with global oil and petrochemical companies and large international diversified chemical companies. Several of these producers are seeking to develop materials from renewable sources that could compete with our products. Moreover, a number of established companies and new entrants have announced intentions to develop renewable alternatives for existing chemical products used in our near-term focus markets. Given our leading position in decarbonized materials, we also expect to compete with alternative technologies targeting different sources of emissions. These competitors include electric vehicles, renewable power generation, and food technology. While we do not anticipate competing directly for market share with producers of these technologies, we expect to compete for wallet share from customers looking to reduce overall carbon emissions throughout their supply chain and operations. Our Competitive Strengths We believe that our PET closure technology and products offer a breakthrough in performance and sustainability for packaging. Our competitive strengths related to that technology and product portfolio include: • Mono-Material Solution for Improved Recycling Circularity. Mono-material products are made with one type of material. They are typically easier to recycle than products made from multiple materials. For Origin PET closures, there is no need to separate caps from bottles during the recycling process, as there is with containers whose caps and bottles are made of different materials. We believe this could be especially valuable for tethered cap solutions. We are developing a tethered PET closure, which we anticipate will be the first commercially produced tethered PET closure. • Can Make Products Last Longer. We believe our caps have the potential to extend product shelf life because they are made from PET, which offers improved gas barrier properties compared with common cap materials HDPE (high-density polyethylene) and polypropylene, preventing oxygen from getting in and CO2 from getting out. • Enables Lighter Weight Products. Because PET offers improved mechanical properties compared with other common cap materials, less plastic is needed to achieve the same or better performance, such as gas barrier, when produced with our proprietary approach. Lighter weight caps provide an important advantage in a market in which our potential customers have publicly declared targets for reducing plastic consumption and efforts to make caps as light as possible, also known as “lightweighting.” • Expands Use of Recycled PET. Our caps can be made with any type of PET, whether virgin PET, bio- based PET, or recycled PET (“rPET”), without the need for custom polymers, enabling customers to produce containers with higher rPET content. • User Experience. Our PET closure provides a satisfying user experience, from its feel to the sound it makes when opened. This is key to product adoption because it meets the expectations of consumers and the world's leading food and beverage brands. Our PET caps offer aesthetically pleasing clarity and transparency, differentiating them from incumbent caps. • Cost Competitive. We expect that our patent-pending PET closures will have a commercially competitive cost basis when compared with HDPE and polypropylene, which to date no other PET cap has been able to achieve, despite past attempts within the industry. This competitive cost stems from Origin's our unique manufacturing system, technology, and process.

9 • Diverse Product Formats and Applications. Our manufacturing system for producing PET closures, which we call the Origin CapFormer System, is highly versatile, capable of producing many different formats of closures for a wide variety of food and beverage applications. Our first cap is the PCO compliant 1881 closure for beverages. We announced a tethered version of that closure in 2024. Future formats could include different beverage formats, food closures, and more, allowing us broad access to the $65 billion closures market. We believe that our furanics technology can replace petroleum as the foundational feedstock for the materials economy. Our competitive strengths related to that technology include: • Flexible platform enables drop-in solutions serving a large addressable market. We believe that our furanics technology is capable of helping to address a substantial global market that is just beginning to transition from petroleum-based materials to sustainable materials. Many of our products are drop- in replacements for traditional petrochemicals, enabling customers to use our products in their existing manufacturing processes to produce chemically and physically identical end products with little to no change in customer behavior. • Abundant, low-cost and historically price-stable feedstock. Our furanics technology can use timber and forest residues such as pine pulpwood, which is currently abundant and renewable, as its base-case feedstock. The feedstock for the pulp industry in North America is plentiful and the cost has historically been relatively low and stable compared with the cost of oil. The market for these wood-based feedstocks tends to be local due to relatively high transport costs, and therefore is insulated from typical commodity price volatility. Furthermore, pulpwood feedstock does not compete for use as a food source, insulating products made from such feedstock from demand price pressures faced by other agricultural-based renewable feedstocks such as corn and sugarcane. • Carbon Footprint. We believe our products can help enable prospective customers to achieve their net zero carbon emissions commitments by transitioning away from fossil-based materials towards

10 materials made with our furanics technology, which can use sustainable, non-food, plant-based feedstock. • High Barriers to Entry. Over more than a decade, we have generated a robust patent portfolio as well as critical trade secrets. We believe our competitors now significantly lag behind us and will be unable to replicate the efficiency, yield and quality of our process, as we expect to continue to improve our existing technology and processes. Business Strategy Our goal is to build a commercially successful business that can scale and meet current and future expected demand for sustainable and performance enhanced materials. As we advance and scale up our PET closures business, furanics technology, and other application development, we expect to introduce manufacturing capacity, which may include acquiring production lines or construction of chemical plants, that can produce sustainable materials and product applications. We also expect to continue to develop new materials and product applications, together with our partners, to maintain and increase our competitive advantages. Key elements of our strategy include: Near-term revenue generation through the sale of PET closures: • We are focusing our available human and cash resources on developing near-term, recurring revenues through our PET closures. We expect a majority of our near-term revenues to be derived from products sold into the closures markets. Scale-up of our closures business: • Growth levers include adding additional production lines, technology advancements that could increase throughput and efficiency per line, developing new formats including non-beverage formats, and developing additional product features such as tethers designed to keep caps connected to bottles. • Licensing Origin CapFormer Systems to commercial partners for the production of PET closures may also play a role in revenue generation.

11 Category leading innovation in PET: • We expect to develop a portfolio of products from our PET closure technology and manufacturing process. Research and development will enable continual improvement and the development and refinement of novel products from this technology platform. We expect to begin with the 1881 closure format and we expect to produce larger caps for different beverage types as well as food containers. Operational and manufacturing excellence: • We believe that our manufacturing excellence will drive continual improvements in process efficiency in the production of PET closures, through a combination of in-house expertise and strategic partners specializing in operations. PET closure manufacturing entails the procurement of PET sheet, processing sheet into closures with our CapFormer Systems, and the delivery of closures to customers who will apply our closures to bottles using commercial bottling lines. • We plan to continue to expand and develop new partnerships across the value chain. Our strategy includes, among other things, entering into strategic partnerships with subsystem manufacturers whose equipment is used in Origin CapFormer Systems. We will partner with organizations capable of providing us with best-in-class capabilities to efficiently build, ship, and assemble CapFormer Systems as well as operators who will assist in the production process. Development of furanics technology and biomass conversion platform for long-term revenue generation: • Origin 1 is a strategic asset which we plan to use to qualify higher-value applications for our intermediates CMF and HTC. Origin 1 commenced commercial-scale production in October 2023. • Future Origin biomass conversion plants are expected to focus on supplying products that serve our markets of interest. CMF applications could include the FDCA-based polymers PEF and PETF for advanced packaging, textiles, and other potential applications. Our current strategy for carrying out development work and technology scale-up beyond Origin 1 depends on near-term revenue from products like our PET closures and our ability to secure substantial financial support from strategic partners.

12 Raw Materials Supply The Origin CapFormer System can produce PET closures from any type of PET, whether virgin PET, rPET, bio- based PET, or blends of these, depending on customer preference. The ability to incorporate rPET into closures increases the amount of recycled content for products and supports customers' ability to make and claim 100% PET (or even rPET) containers, including the caps. Our raw materials are established commodities and we do not require custom polymers to produce our caps. We believe we will be able to source materials as needed to manufacture closures. Our furanics technology can produce building block chemicals from a variety of abundant, low-cost bio- feedstocks including wood residues and wood processing waste. Our process was designed to be able to take advantage of idled and aging pulp mills and may be co-located with such mills to secure access to existing site- specific feedstock supplies and skilled labor while lowering required capital investment. Research and Development Research and development is important to the success of our closures business. Origin’s innovation involves a new manufacturing process for PET closures that is different from the injection and compression molding methods traditionally used for HDPE and polypropylene closures. Different closure formats have different geometries and technical needs, including tolerances to pressure and temperature. We are advancing the practice of thermoforming to meet the performance demands of closures, performing research and development to define and refine the thermoforming process to meet the geometries, tolerances, and performance specifications of producing PET closures using our technologies. Our research and development enables technology advancements designed to increase line throughput and efficiency, develop new formats beyond beverages, and develop additional features such as tethers. At times, we perform research and development with third-party research organizations, strategic partners, and equipment subsystem manufacturers. Our first PET closure production line is located in Reed City, Michigan.

13 For our furanics technologies, including our biomass conversion platform, and related intermediates, we have been developing commercialization pathways focused on high-value applications. We operate an in-house laboratory and pilot-scale manufacturing facilities in West Sacramento, California and Sarnia, Ontario. Our furanics development work has a characteristically longer development cycle than our closures R&D. To further scale our furanics technologies, we are considering additional process development work or securing a financing partner in support of commercialization. Intellectual Property Our patent portfolio is comprised of 50 issued patents focused on the conversion of biomass to CMF and HTC and downstream derivatives thereof, and 28 issued patents focused on closures and their production. We intend to retain exclusive rights to commercially work its biomass to CMF and HTC pathways. We also rely on trade secrets, know-how and continuing technological innovation to develop and maintain our proprietary position. Patents. As of March 1, 2025, the issued patents in our portfolio are broken down as follows: Issued U.S. Utility Patents Furanics Closures 28 0 Issued Foreign Utility Patents Furanics Closures 22 0 Issued Foreign Design Patents Furanics Closures 0 28 The term of individual patents depends upon the legal term of the patents in countries in which they are obtained. In most countries, including the United States, the patent term is generally 20 years from the earliest date of filing a non-provisional patent application in the applicable country. In the United States, a patent’s term may, in certain cases, be lengthened by patent term adjustment, which compensates a patent holder for administrative delays by the United States Patent and Trademark Office (“USPTO”) in examining and granting a patent. A patent's term also may be shortened if the patent is terminally disclaimed over a commonly-owned patent or a patent naming a common inventor and having an earlier expiration date. As of March 1, 2025, our pending non-provisional applications are broken down as follows: Pending U.S. Utility Applications Furanics Closures 3 7 Pending U.S. Design Applications Furanics Closures

14 0 4 Pending Foreign Utility Applications Furanics Closures 16 19 Pending Foreign Design Applications Furanics Closures 0 41 Our furanics technology—biomass to CMF and HTC—is protected with patents, trade secrets, and know-how. We have 28 issued patents in the U.S. that will expire between 2031 and 2036 and 23 issued patents in foreign jurisdictions including Brazil, China, Europe, Japan, Korea, Mexico and Malaysia that will expire between 2031 and 2036. Our closures technology is protected with patents, trade secrets, and know-how. We have 26 issued design patents in foreign jurisdictions including Australia, Brazil, Canada, the United Kingdom, India, Korea, Turkey, and Taiwan that will expire between 2039 and 2049. Finally, we have 60 pending international applications directed to our closures technology in foreign jurisdictions including ARIPO, Australia, Brazil, Canada, China, Europe, India, Israel, Japan, Mexico, Saudi Arabia, South Africa, Taiwan, the United Kingdom, Trade secrets. We maintain a secure digital vault of our trade secrets with heightened confidentiality protections. Access to this vault is limited to a select group and is granted on a need-to-know basis. Further, the information in the vault is left strategically incomplete and requires corroboration from referenced internal documents to ensure that the entirety of any trade secret is known only by someone who has access to each such document. Our employees are required to participate in invention assignment and non-disclosure protocols to further ensure the protection of our trade secrets. Know-how. An important aspect of our intellectual property, in addition to our patent portfolio and trade-secrets, is the depth of understanding and proficiency we gained in the behavior of the Origin technology platform’s chemical reactions, the handling of feedstocks, and the process-ability of feedstocks given certain conditions. This know-how into our process and materials is carefully captured in many ways, such as by being photographed, videoed, measured, quantified, summarized, compared, and otherwise described. Within this information set, we have identified many key insights without which we believe a would-be competitor could not successfully operate in our industry or replicate our results.

15 Regulatory Several states like California, Maine, and New Jersey, as well as Canada and the European Union, have enacted or are considering “minimum recycled content” regulations mandating certain minimum post-consumer recycled content in certain types of packaging, including, specifically, plastic beverage containers. Legislative and regulatory measures to mandate or encourage waste reduction and recycling also have been considered, or are under consideration, in jurisdictions where we expect to produce or sell our products. These regulations may present new opportunities for sustainable products like our PET closures, which can be made from recycled PET and be recycled together with the PET containers on which they are used. PET closures may involve food contact and will be regulated by the U.S. Food and Drug Administration (the FDA), the European Food Safety Authority (EFSA) or government authorities in other jurisdictions. For example, our PET closures sold in the European Union are required to be tethered to the bottle or container based on recent regulatory requirements in the region. The production and sale of our chemicals and intermediates that we manufacture and use, including CMF and HTC, and our ongoing research and development activities require authorizations or exemptions under the Toxic Substances Control Act (“TSCA”) administered by the U.S. Environmental Protection Agency (the “EPA”) and the Canadian Environmental Protection Act (“CEPA”) administered by Health Canada and Environment and Climate Change Canada. Our production processes are subject to regulations and permit requirements relating to air emissions, wastewater discharges, waste generation and disposal, and other environmental matters. Employees and Workplace Culture Intentional Culture and Leadership. At Origin, our values inform our decision making and how we act. We are deliberate, open, and transparent about our dedication to our core purpose; to enable the world’s transition to sustainable materials. We have assembled an exceptional team of operations specialists, scientists, engineers, and business leaders to develop and execute our strategic plans. Human Capital. We believe that our ability to attract, retain and motivate exceptional employees is vital to our long-term competitive advantage. As such, our compensation practices, including long-term equity incentive plans, are designed to drive sustainable performance and align employee incentives with shareholder values. As of December 31, 2024, we had approximately 82 employees located in the United States and 27 employees in Canada, all of whom were full-time employees. None of our employees is subject to a collective bargaining agreement and we believe we have a good relationship with our employees. Corporate Information Origin was formerly known as Artius Acquisition Inc. (“Artius”). Artius was originally registered under the Companies Law of the Cayman Islands on January 24, 2020, as a special purpose acquisition company formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization, or other similar business combination with one or more target businesses. On June 25, 2021, we consummated a merger pursuant to that certain Agreement and Plan of Merger and Reorganization, dated as of February 16, 2021 (as amended by the letter agreement dated March 5, 2021, the “Merger Agreement”), by and among Artius, Zero Carbon Merger Sub Inc., a Delaware corporation and a direct, wholly owned subsidiary of Artius (the “Merger Sub”), and Micromidas, Inc., a Delaware corporation doing business as Origin Materials (“Legacy Origin”). Pursuant to the terms of the Merger Agreement, Artius effected a business combination with Legacy Origin through the merger of Merger Sub with and into Legacy Origin, with Legacy Origin as the surviving company and as our wholly-owned subsidiary. We refer to this as the “Merger” and, collectively with the other transactions

16 described in the Merger Agreement, the “Business Combination.” In connection with the closing of the Business Combination (such time is referred to herein as the “Effective Time”), we changed our name to Origin Materials, Inc. Unless the context indicates otherwise, references in this Annual Report to the “Company,” “Origin,” “we,” “us,” “our” and similar terms refer to Origin Materials, Inc. (f/k/a Artius Acquisition Inc.) and its consolidated subsidiaries (including Legacy Origin). References to “Artius” refer to the predecessor company prior to the consummation of the Business Combination. Additional Information Origin’s annual reports on Form 10-K, quarterly reports on Form 10-Q, current reports on Form 8-K, and all amendments to those reports are available free of charge on the Company’s website at https://investors.originmaterials.com as soon as reasonably practicable after such material is electronically filed with, or furnished to, the Securities and Exchange Commission. Item 1A. Risk Factors The following risk factors apply to our business and operations. These risk factors are not exhaustive, and investors are encouraged to perform their own investigation with respect to our business, financial condition and prospects. We may face additional risks and uncertainties that are not presently known to us, or that we currently deem immaterial, which may also impair our business. The following discussion should be read in conjunction with the consolidated financial statements and notes to such consolidated financial statements included elsewhere in this Annual Report and the “Management’s Discussion and Analysis of Financial Condition and Results of Operations” section of this Annual Report. Risks Related to Our Business We are an early stage company with a history of losses and our future profitability is uncertain. We have had a history of net losses due to our primary focus on research and development, plant construction, capital expenditures and early-stage commercial activities. Substantially all of our net losses since inception have resulted from our plant construction, research and development, and general and administrative costs associated with our operations. We have only recently begun generating revenue, and we expect that our net losses from operations will continue for the foreseeable future. Based on our estimates and projections, which are subject to significant risks and uncertainties, we expect our commercial scale production to be limited for several years and challenges with the design, construction, funding, and labor and equipment supply for our closures manufacturing lines and plants may further delay this timeline. Even as we commercialize and begin to generate revenue, we may not become profitable for many years, if at all. Our potential profitability is dependent upon many factors, including our ability to complete development of our closures manufacturing lines and effectively operate those lines, as well as our current Origin 1 plant, maintain an adequate supply chain, anticipate and react to demand for our products, manufacture our products on a commercial scale, secure additional customer commitments, and otherwise execute our growth plan. The rate at which we incur losses may be higher in future periods as we: • develop our PET closure business; • increase our spending on strategic partnerships;

17 • increase production at our Origin 1 plant; • increase our sales and marketing activities; and • expand our commercial production capabilities and incur costs associated with developing and commercializing our closures and furanics technologies. Because we will incur the costs and expenses from these efforts before receiving meaningful revenue, our losses in future periods could be significant. We may find that these efforts are more expensive than we currently estimate or that these efforts may not result in revenues, which would further increase our losses. We may not manage growth effectively. Our failure to manage growth effectively could harm our business, results of operations and financial condition. We anticipate that a period of expansion may be required to address potential growth. This expansion will place a significant strain on our management, operational and financial resources. To manage the growth of our operations and personnel, we must establish appropriate and scalable operational and financial systems, procedures and controls and establish and maintain a qualified finance, administrative and operations staff. We may be unable to hire, train, retain and manage the necessary personnel or to identify, manage and exploit potential strategic relationships and market opportunities. For example, our former co-Chief Executive Officer, Rich Riley, resigned from his position effective December 31, 2024. Our business plan assumes we can secure substantial additional project financing and/or government incentives, which may be unavailable on favorable terms, if at all. We expect to need substantial additional project financing and/or government incentives in order to execute our growth strategy and expand our manufacturing capability to advance our PET closures and furanics technology. We have not yet secured all such project financing and government incentives, and may not in the future, and they may not be available on commercially reasonable terms, if at all. In particular, our ability to obtain financing for the construction of future manufacturing lines and plants may depend, in part, on our ability to first enter into customer agreements that demonstrate sufficient demand to justify such construction. If we are unable to obtain such financing and/or government incentives, or secure sufficient customer agreements, on commercially reasonable terms, or at all, we will not be able to execute our growth strategy. To the extent that we raise additional capital through the sale of equity or convertible debt securities, your ownership interest will be diluted, and the terms of those securities may include liquidation or other preferences that adversely affect your rights as a common stockholder. Debt financing and preferred equity financing, if available, may involve agreements that include covenants limiting or restricting our ability to take specific actions, such as incurring additional debt, making acquisitions or capital expenditures or declaring dividends. Debt financing could also have significant negative consequences for our business, results of operations and financial condition, including, among others, increasing our vulnerability to adverse economic and industry conditions, limiting our ability to obtain additional financing, requiring the dedication of a substantial portion of our cash flow from operations to service our indebtedness, thereby reducing the amount of our cash flow available for other purposes, limiting our flexibility in planning for, or reacting to, changes in our business, and placing us at a possible competitive disadvantage compared to less leveraged competitors or competitors that may have better access to capital resources. If we raise additional funds through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties, we may have to relinquish valuable rights to our technologies, future revenue

18 streams, research programs or products, grant licenses on terms that may not be favorable to us, or make other concessions. If we are unable to raise additional funds through equity or debt financings or other arrangements when needed, we may be required to delay, limit, reduce or terminate our commercialization, research and development efforts or grant rights to third parties to market and/or develop products that we would otherwise prefer to market and develop ourselves. Government grants, incentives or subsidies, may have terms that limit or restrict certain of our planned operations, thereby requiring us to alter our operating plans and materially impacting our financial projections and projected results of operations. Government grants may also be terminated, modified or recovered under certain conditions without our consent. We are exposed to credit risk in our activities related to potential nonperformance by customers. In the normal course of our business, we provide payment terms to certain of our customers. As a result, our business could be adversely affected if our customers’ financial condition deteriorates and they are unable to repay us. This risk may increase if the general economic downturn continues and further affects a large number of our customers or if our customers fail to manage their business effectively or adequately disclose their financial condition to us. Certain of our suppliers, including suppliers of equipment used in some of our manufacturing facilities, have in the past and may in the future declare bankruptcy or become insolvent, which disrupted our supply chain and required us to identify alternative suppliers, and may again in the future resulting in delay and/or additional cost. In addition, certain of our supply chain activation vendors have failed to pay and/or expressed doubt about their ability to timely pay, or pay at all, amounts due to the Company. The Company manages the risk of customer default through a combination of due diligence, contractual terms, and a diversified customer base. The number of customers, as well as our ability to discontinue service, contributes to reduce credit risk with respect to accounts receivable. Despite such mitigation efforts, customer defaults may occur and we may be unable to recover all or any of the amounts due to the Company, or we may be forced to incur, and in one case in which a supply chain activation vendor accepted prepayments from us for product the vendor failed to deliver, have incurred, legal and other collection costs to recover such amounts. Our outstanding secured and unsecured indebtedness, ability to incur additional debt and the provisions in the agreements governing our current debt, and certain other agreements, could harm our business, financial condition, results of operations and prospects. Our debt service and similar obligations could have important consequences to us for the foreseeable future, including that our ability to obtain additional financing for capital expenditures, working capital or other general corporate purposes may be impaired and we may be or become substantially more leveraged than some of our competitors, which could place us at a relative competitive disadvantage and make us more vulnerable to changes in market conditions and governmental regulations. We are required to maintain compliance with covenants under our debt and similar agreements. There are and will be operating or financial restrictions and covenants in certain of our debt and similar agreements, including the promissory notes and prepayment agreements we are party to, as well as certain other agreements to which we are or may become a party. These limit, among other things, our ability to incur certain additional debt, create certain liens or other encumbrances and sell assets. These covenants could limit our ability to engage in activities that may be in our best long-term interests. Our failure to comply with certain covenants in these agreements could result in an event of default under the various debt and similar agreements, allowing lenders to accelerate

19 the maturity for the debt under these agreements and to foreclose upon any collateral securing the debt. Under such circumstances, we might not have sufficient funds or other resources to satisfy all of our obligations. Risks Related to Our Operations and Industry We have not yet produced any of our products in large commercial quantities. We have no experience in producing large quantities of our products. While we have succeeded in producing small amounts of our intermediate chemicals in our pilot plants and Origin 1 plant, as well as relatively small amounts of our PET closures, for customer evaluation, we have only relatively recently commenced commercial- scale production of our chemical intermediates and PET closures. There are significant technological and logistical challenges associated with producing, marketing, selling, and distributing products in the specialty chemicals and closures industries, including our products, and we may not be able to resolve all of the difficulties that arise in a timely or cost-effective manner, or at all. While we believe that we understand the engineering and process characteristics necessary to successfully build and operate additional planned facilities and scale up to larger and/or additional facilities, we may be unable to cost-effectively manage such construction and operation at a scale or quality consistent with customer demand in a timely or economical manner or at all. Construction of manufacturing lines for production of our PET closures, or of additional plants beyond Origin 1, may not be completed in a timely manner or completed in a cost-effective manner or at all. Any delays in or failure to finance and complete the construction of manufacturing facilities could severely impact the implementation and commercialization of our PET closures and furanics technologies. Our ability to implement our furanics technology platform and to satisfy our customer demand and contractual obligations depend, in part, on our ability to secure financing for and complete construction of several commercial scale plants and, in part, on our ability to secure debt financing for and to procure several manufacturing lines to produce our PET closures. In particular, we have not selected a site for any of our future planned furanics plants or many of our planned PET closures manufacturing lines. We may have difficulty finding sites with appropriate infrastructure and access to raw materials and skilled labor. With respect to future plants, we also do not have agreements with engineering, procurement or construction firms, or with some of the firms we expect to rely on for our PET closures supply chain. Consequently, we cannot predict on what terms such firms may agree to design and construct our future manufacturing facilities. Our business, financial condition, results of operations and prospects could be severely impacted, we may lose customers and customer demand, and we could face litigation if we are unable to construct these facilities and procure and set up our manufacturing lines within the planned timeframes, which are relevant to some of our customers' carbon reduction, sustainability, marketing, or other goals, or in a cost-effective manner, or at all due to a variety of factors. Such factors include, without limitation, a failure to acquire or lease property on which to build and operate our manufacturing facilities, a stoppage of construction as a result of epidemics, disruptions caused by the recent global sanctions imposed against Russia following its military intervention in Ukraine, a major supplier of certain metals such as nickel used in materials of construction, unexpected construction problems, permitting and other regulatory issues, severe weather, inflationary pressures, labor disputes, or issues with subcontractors or vendors, including payment disputes, which we have previously experienced.

20 The construction and commissioning of any new project is dependent on a number of contingencies some of which are beyond our control. There is a risk that significant unanticipated costs or delays could arise due to, among other things, errors or omissions, unanticipated or concealed project site conditions, including subsurface conditions and changes to such conditions, unforeseen technical issues or increases in plant and equipment costs, insufficiency of water supply and other utility infrastructure, inadequate contractual arrangements, or design changes and associated or additional technical development work related, for example, to new or different process steps or product streams, or changes in the scale of equipment or operations. Should these or other significant unanticipated costs or delays arise, this could have a material adverse impact on our business, financial performance and operations. No assurance can be given that construction will be completed on time or at all, or as to whether we will have sufficient funds available to complete construction. We currently rely on, and plan to rely on, a limited number of manufacturing facilities to meet near-term customer demand for our PET closures and for our future intermediate chemical sales. Our operating plan assumes that we will rely on a limited number of manufacturing facilities to meet customer demand and that these facilities will supply most of our products until additional facilities can be brought online. Adverse changes or developments affecting these facilities could impair our ability to produce our products. Any shutdown or period of reduced production at these facilities, which may be caused by regulatory noncompliance or other issues, as well as other factors beyond our control, such as severe weather conditions, natural disaster, fire, power interruption, work stoppage, disease outbreaks or pandemics, equipment failure or delay in supply delivery, would, among other things, significantly disrupt our ability to recognize revenue, execute our expansion plans, and meet our contractual obligations and customer demand. In addition, our facilities' equipment may be costly to replace or repair, and our equipment supply chains may be disrupted in connection with potential changes in tariffs and trade barriers (such as those recently imposed on China, Canada, and Mexico by the U.S. President as well as retaliatory tariffs and barriers imposed by those countries), pandemics, sanctions (such as those imposed against Russia following its military intervention in Ukraine), or other factors. In addition, certain of our suppliers, including of equipment used in some of our manufacturing facilities, have in the past and may in the future declare bankruptcy or become insolvent, which could disrupt our supply chain or require us to identify alternative suppliers, resulting in delay and/or additional cost. If any material amount of our equipment is damaged, we could be unable to predict when, if at all, we could replace or repair such equipment or find suitable alternative equipment, which could adversely affect our business, financial condition, results of operations and prospects. Performance guarantees may not be sufficient to cover damages or losses, or the guarantors under such guarantees may not have the ability to pay. We may be unable to obtain appropriate types or amounts of insurance, and any insurance coverage we have may be insufficient to cover all of our potential losses or continue to be available to us on acceptable terms, or at all. We may be delayed in procuring or be unable to procure necessary capital equipment. While much of the equipment we use to produce our products is currently widely available, we rely on outside companies to continue to manufacture the equipment necessary to produce our products. In addition, some equipment we use to produce our products requires significant lead time to manufacture. If our suppliers of manufacturing equipment are unable or unwilling to provide us, or if we experience significant delays in obtaining the necessary manufacturing equipment, or parts necessary to repair and maintain that equipment, our business, we may be unable to make our products and our results of operations and financial condition could be adversely affected. The repair, maintenance, or construction of our manufacturing equipment may also require a substantial portion of certain materials and supplies relative to the overall global supply of such materials and supplies. If we

21 are unable to secure an adequate supply of such materials and supplies on commercially reasonable terms, or at all, such repair, maintenance, or construction may be delayed or terminated. We rely on a limited number of customers for a significant portion of our near-term revenue. We currently have commercial arrangements with a limited number of customers from which we expect to derive a significant portion of near-term revenue. Our top two customers from product sales, in the aggregate, accounted for approximately 93% and 67% as of December 31, 2024 and 2023, respectively, of total accounts receivable outstanding balances and accounted for approximately 96% and 77% of total revenues for the years ended December 31, 2024 and 2023, respectively. Our business, results of operations, and financial condition may be harmed by the loss of one or more of our significant customers, a substantial reduction in their orders, their failure to enter into offtake agreements or purchase commitments that support necessary financing, or at all, or to purchase product, their unwillingness to extend contractual deadlines if we fail to meet production, product, or specification requirements, their inability to perform under their contracts or a significant deterioration in their financial condition. If we fail to perform under the terms of these agreements, the customers could seek to terminate the agreements and/or pursue damages against us, which could harm our business. Our products may not achieve market success, but will still require significant costs to develop, which could harm our business, financial condition, and results of operations. We believe that we must dedicate significant resources to develop and commercialize our products before knowing whether there will be market acceptance of our products. We may never commercialize the products we develop, and even if commercialized, the performance of these products is uncertain. For example, we currently have predominantly non-binding customer commitments for commercial quantities of our products. Some prospective customers are currently evaluating and testing our products prior to making large-scale purchase decisions. Other products we expect to develop have not yet started customer evaluation and testing. The successful commercialization of our products depends on our customers’ ability to commercialize the end- products that use our products, which may gain market acceptance slowly, if at all. Furthermore, the technology for our products is new, and the economic and physical performance, including their ultimate carbon footprint, recyclability, circularity, or other expected sustainability benefits, is uncertain. The market for our PET closures and for decarbonized materials made from our furanics technology, still is nascent and subject to significant risks and uncertainties. Market acceptance of our products will depend on numerous factors, many of which are outside of our control, including, among others: • public acceptance of such products; • our ability to produce products of consistent quality that offer functionality comparable or superior to existing or new products; • our ability to produce products fit for their intended purpose; • our ability to produce new products or customizations of existing products to match changes in public demand; • our ability to timely obtain necessary regulatory approvals for our products; • the speed at which potential customers qualify our products for use in their products;

22 • the pricing of our products compared to competitive and alternative products, including petroleum- based plastics or incumbent HDPE and polypropylene closures, as well as similar products made by different methods such as PET closures made using injection or compression molding methods; • the strategic reaction of companies that market competitive products or have intellectual property rights that may be necessary to produce our products economically, effectively, or at all; • our reliance on third parties who support or control distribution channels; and • general market conditions, including fluctuating demand for our products. Our industry is highly competitive, and we may lose market share to producers of products that can be substituted for our products, which may have an adverse effect on our results of operations and financial condition. The closures and specialty chemicals industries are highly competitive, and we face significant competition from incumbent HDPE and polypropylene closures businesses as well as incumbent injection and compression molding technologies, which have been widely adopted. Our furanics products are expected to compete with those of large established producers of fossil-based materials, recycled fossil-based materials, and a variety of current and future producers of low-carbon, biodegradable, or renewable resource-based materials. Many of our current competitors have longer operating histories, greater name recognition, larger customer bases and significantly greater financial, sales and marketing, manufacturing, distribution, technical and other resources than us. Recently, certain of our competitors in the closures industry, as well as others in the specialty chemicals industry, have announced products that may compete directly with our own. Our competitors may be able to adapt more quickly to new or emerging technologies, changes in customer requirements and changes in laws and regulations. In addition, current and potential competitors have established or may establish financial or strategic relationships among themselves or with existing or potential customers or other third parties. Accordingly, new competitors or alliances among competitors could emerge and rapidly acquire significant market share. Our competitors may also improve their relative competitive position by successfully introducing new products or products that can be substituted for our products, improving their manufacturing processes, or expanding their capacity or manufacturing capabilities. Further, if our competitors are able to compete at advantageous cost positions, this could make it increasingly difficult for us to compete in markets for less-differentiated applications. If we are unable to keep pace with our competitors’ product and manufacturing process innovations or cost position, it could harm our results of operations, financial condition and cash flows. The commercial success of our closures business may be influenced by the price of incumbent HDPE or polypropylene, and of closures made from these materials, relative to the price of PET, and of closures made from this material, while commercial success of our furanics technology may be influenced by the price of petroleum relative to the price of non-fossil feedstocks like forrest residues or old corrugated cardboard. Our commercial success may be influenced by the cost of HDPE or polypropylene relative to PET, as well as the relative price of closures made from these materials, while commercial success of our furanics technology could be influenced by the cost of our biomass-derived products relative to petroleum-based products. Negative impacts could result from changes in the relative prices of HDPE, polypropylene, and PET, and of closures made from these materials. Cheaper HDPE or polypropylene relative to PET could drive our customers to shift purchases away from our PET closures and toward closures made from HDPE or polypropylene, which they currently use in large numbers. The cost of petroleum-based products is in part based on the price of petroleum, which is subject

23 to historically fluctuating prices. Our furanics technology is designed to use biomass feedstocks such as timber and forest residues, which historically have experienced low volatility relative to petroleum. Increases in the price of bio-based feedstocks or decreases in the price of petroleum, or our use of bio-based feedstocks such as sugars or starches that may have higher volatility or cost than timber and forest residues, could make products derived from our furanics technology less competitive than their petroleum-based counterparts and require price reductions to stay attractive in the marketplace, harming our revenues. Increases or fluctuations in the costs of our raw materials may adversely affect our cost structure. The price of raw materials may be impacted by external factors, including uncertainties associated with war, terrorist attacks, weather and natural disasters, potential changes in tariffs and trade barriers (such as those recently imposed on China, Canada, and Mexico by the U.S. President as well as retaliatory tariffs and barriers imposed by those countries), health epidemics or pandemics (such as COVID-19), civil unrest, the effects of climate change or political instability, plant or production disruptions, strikes or other labor unrest, inflationary pressures, breakdown or degradation of transportation infrastructure used in the delivery of raw materials, changes in laws or regulations in any of the countries in which we have significant suppliers, or tariffs or other trade restrictions imposed on or by such countries. Our PET closures are designed to use PET, including recycled PET, as a raw material. Similarly, our furanics technology is designed to use biomass such as local timber and forest residues as raw materials. The cost of these raw materials is generally influenced by supply and demand factors, and our operating plans include assumptions that the materials we intend to use as feedstocks will be available at prices similar to historic levels with low volatility. As we continue to expand our production, we will increase our demand for PET to produce our PET closures, and of timber and forest residues to produce our chemical intermediates, which may alter the anticipated stability in the costs of our raw materials and potentially drive an increase in their cost. Additionally, we are not the only company seeking to convert timber and forest residuals into products that replace traditionally petroleum- derived equivalents. Positive momentum gained by other companies may impact the supply/demand balance. Our results of operations will be directly affected by the cost of raw materials and other inputs, like the amount and cost of steam in the manufacturing process. The cost of raw materials and energy, such as to produce the steam required during feedstock processing comprises a significant amount of our total cost of goods sold and, as a result, movements in the cost of raw materials, and in the cost of other inputs, will impact our profitability. Because a significant portion of our cost of goods sold is represented by these raw materials, our gross profit margins could be adversely affected by changes in the cost of these raw materials if we are unable to pass the increases on to our customers. If our raw material prices experience volatility, there can be no assurance that we can continue to recover raw material costs or retain customers in the future. As a result of our pricing actions, customers may become more likely to consider competitors’ products, some of which may be available at a lower cost. Significant loss of customers could adversely impact our results of operations, financial condition and cash flows.

24 We are dependent on third-party suppliers and service providers, some of which are sole source suppliers, who may fail, and in some cases have failed to deliver raw materials or equipment or fail to supply needed services at all or according to schedules, prices, quality and volumes that are acceptable to us, or we may be unable to manage these supplies effectively. Parts of our supply chain currently are dependent on a limited number, and in some cases a single, third-party supplier or service provider for key inputs, equipment, and services including for conversion of our chemical intermediates produced by our Origin 1 plant into downstream derivatives and applications and for production of our PET closures. We have not yet secured agreements with our preferred (or the only) supplier of some of these inputs, equipment, and services, and we may be unable to do so on a time frame or terms we find acceptable, or at all. Our reliance on few or single suppliers in a limited number of locations risks multiple supply chain vulnerabilities. For example, certain of our suppliers have in the past and may in the future declare bankruptcy or become insolvent, which could disrupt our supply chain or require us to identify alternative suppliers, resulting in delay and/or additional cost. The military conflict in Ukraine can exacerbate the risks to our supply chain to the extent our suppliers depend on raw materials, components, or parts from Russia or Ukraine including, for example, certain metals used in materials of construction. Finding substitute suppliers and service providers, to the extent they exist, may be expensive, time-consuming, or impossible and could interrupt or delay the supply of our products causing us to lose revenue and potentially harm our customer relationships or reputation and expose us to contractual remedies under our supply agreements. To the extent we do not have firm commitments from our third-party suppliers or service providers for a specific time period or capacity, quantity, and/or pricing, our suppliers may allocate capacity to their other customers, which could make that capacity unavailable to us when needed or at reasonable prices and prevent us from delivering our products on time or at all. For instance, if we are unable to timely obtain shipping services for our PET closures, we may need to store those closures for extended periods during which they could degrade or become unusable, forcing us to dispose of them and/or replace them at additional cost. Any of these occurrences could adversely affect our supply chain and cause serious harm to our business. We may be unable to secure agreements with local suppliers for the necessary amount of raw materials needed to produce our PET closures or Furanic Intermediates in certain circumstances. Additionally, if our suppliers do not accurately forecast and effectively allocate sufficient materials to us or if they are not willing to allocate sufficient supplies to us, it may reduce our access to raw materials needed for our manufacturing and require us to search for new suppliers. The unavailability of any raw materials could result in production delays, idle manufacturing facilities, product design changes and loss of access to important residues supporting our production, as well as impact our capacity to fulfill our obligations under our supply agreements. In addition, unexpected changes in business conditions, materials pricing, labor issues, wars, trade policies, natural disasters, epidemics or pandemics, trade and shipping disruptions, and other factors beyond our or our suppliers’ control could also affect these suppliers’ ability to deliver components to us or to remain solvent and operational. Additionally, we may be unsuccessful in our continuous efforts to negotiate with existing suppliers to obtain cost reductions and avoid unfavorable changes to terms, or source less expensive suppliers for certain materials, especially in light of the overall increases in supply and shipment pricing. Any of these occurrences may harm our business, prospects, financial condition and operating results.

25 If we are required to obtain alternate sources for raw materials, for example because a supplier is unwilling or unable to execute or perform under raw material supply agreements, if a supplier terminates its agreements with us, if a supplier is unable to meet increased demand as our commercial scale production expands, if we are unable to renew its contracts or if we are unable to obtain new long-term supply agreements to meet changing demand, we may not be able to obtain these raw materials in sufficient quantities, on economic terms, or in a timely manner, and we may not be able to enter into long-term supply agreements on terms as favorable to us, if at all. A lack of availability of raw materials could limit our production capabilities, require us to use alternate raw materials such as non-timber feedstocks that may be more expensive or have inferior carbon reduction or other performance characteristics, and prevent us from fulfilling customer orders, and therefore harm our results of operations and financial condition. As the scale of our manufacturing increases, we will also need to accurately forecast, purchase, warehouse and transport raw materials at high volumes to our manufacturing facilities internationally. If we are unable to accurately match the timing and quantities of raw material purchases to our actual needs or successfully implement inventory management and warehousing systems, we may incur unexpected production disruption, storage, transportation and write-off costs, which may harm our business and operating results. Maintenance, expansion and refurbishment of our facilities, the construction of new facilities and production lines, and the development and implementation of new manufacturing processes involve significant risks. Our facilities may require regular or periodic maintenance, upgrading, expansion, refurbishment or improvement. Any unexpected operational or mechanical failure, including failure associated with breakdowns and forced outages, could reduce our facilities’ production capacity below expected levels, which would reduce our production capabilities and ultimately our revenues. Unanticipated capital expenditures associated with maintaining, upgrading, expanding, repairing, refurbishing, or improving our facilities may also reduce our profitability. Our facilities may also be subject to unanticipated damage as a result of natural disasters, terrorist attacks or other events. If we make any major modifications to our facilities or those of third parties in our supply chain, such modifications likely would result in substantial additional capital expenditures and could prolong the time necessary to bring the facility online. We may also choose to refurbish or upgrade facilities based on our assessment that such activity will provide adequate financial returns. However, such activities require time for development and capital expenditures before commencement of commercial operations, and key assumptions underpinning a decision to make such an investment may prove incorrect, including assumptions regarding construction costs and timing, which could harm our business, financial condition, results of operations and cash flows. The development of new manufacturing facilities entails a number of risks and assumptions, including the ability to begin production within the cost and timeframe estimated and to attract a sufficient number of skilled workers to meet the needs of the new facility. For example, the anticipated costs of constructing our future plants are far higher than initially estimated and timelines have been delayed as a result of efforts to redesign the project to reduce those costs. Additionally, our assessment of the projected benefits associated with the construction of new manufacturing facilities, including production lines for our PET closures, is subject to a number of estimates and assumptions, which in turn are subject to significant economic, competitive and other uncertainties that are beyond our control. If we experience delays or increased costs, our estimates and assumptions are incorrect, or other unforeseen events occur, our business, ability to supply customers, financial condition, results of operations and cash flows could be adversely impacted.

26 Finally, we may not be successful or efficient in developing or implementing new production processes. Innovation in production processes involves significant expense and carries inherent risks. Such risks may include difficulties in designing, developing, implementing, and scaling up new process technologies, development and production timing delays, lower than anticipated manufacturing yields, product defects, and inability to consistently meet customers’ product specifications, performance and carbon intensity, or cost requirements, among others. Errors, defects in materials, operating permit and license delays, customer product returns, interruption in our supply of materials or resources, and disruptions at our facilities or those of our partners due to accidents, maintenance issues, or unsafe working conditions, all could affect the timing, efficiency, or success of our production processes. Such production issues can lead to increased costs and may affect our ability to meet product demand, which could adversely impact our business and results from operations. We may not be successful in finding future strategic partners for continuing development of our manufacturing facilities and feedstock opportunities, or tolling and downstream conversion of our products. We may seek to develop additional strategic partnerships to develop our manufacturing facilities, increase feedstock supply due to manufacturing constraints or capital costs required to develop our products and plants. We may not be successful in our efforts to establish such strategic partnerships or other alternative arrangements for our products, technology, or manufacturing facilities because our research and development pipeline may be insufficient, our products or manufacturing facility designs or processes may be deemed to be at too early of a stage of development for collaborative effort, or third parties may not view our products or manufacturing facilities as having the requisite potential to demonstrate commercial success. In particular, if we are unable to advance strategic partnerships to fund our development of closures manufacturing lines or plants in addition to our Origin 1, we may be delayed or may never be complete development and construction, which may adversely impact our operation and financial results. If we are unable to reach agreements with suitable collaborators on a timely basis, on acceptable terms, or at all, we may have to curtail the development of our products, delay commercialization or development of manufacturing facilities, reduce the scope of any sales or marketing activities or increase expenditures and undertake development or commercialization activities at our own expense. If we elect to fund development or commercialization activities on our own, we may need to obtain additional expertise and additional capital, which may not be available to us on acceptable terms or at all. If we fail to enter into collaborations and do not have sufficient funds or expertise to undertake the necessary development and commercialization activities, we may not be able to develop additional products or plants, and our business, financial condition, results of operations and prospects may be materially and adversely affected. We may rely heavily on future collaborative and supply chain partners. We have entered into, and may enter into, strategic partnerships to develop and commercialize our current and future research and development programs with other companies to accomplish one or more of the following: • obtain capital, equipment, and facilities; • obtain funding for research and development programs, product development programs, and commercialization activities; • obtain expertise in relevant markets; • obtain access to raw materials;

27 • obtain sales and marketing services or support; • obtain conversion services and other supply chain support; and/or • obtain access to intellectual property and ensure freedom to operate. We may not be successful in establishing or maintaining suitable partnerships, and we may not be able to negotiate collaboration agreements having terms satisfactory to us, or at all. Failure to make or maintain these arrangements or a delay or failure in a collaborative partner’s performance under any such arrangements could harm our business and financial condition. In addition, global supply chain disruptions have caused, and may continue to cause, delays in the shipment of goods, particularly those made in Asian countries. We have incurred, and may continue to incur, additional costs to expedite deliveries of such goods or to obtain substitute goods that are available to us sooner. Continued supply chain disruptions and our efforts to mitigate them may adversely impact our financial condition, results of operations, and cash flows. We have entered into and may in the future enter into collaborations, strategic alliances, or licensing arrangements, which expose us and our intellectual property to competitive risks and limitations associated with third-party collaborations and that may not produce the benefits we anticipate. We have entered, and may in the future enter, into license and collaboration arrangements for the development and production of some of our materials and products. In the future, we may enter into additional license and collaboration arrangements. Any collaboration we enter into is subject to numerous risks. Such risks may include, among others, collaborators’ significant discretion to determine the effort and resources they will apply to the collaboration, to delay or elect not to continue development of a product or process under the collaboration, or to develop, independently or with third parties, products or processes that compete directly or indirectly with our products or manufacturing processes. A collaborator’s development, sales, or marketing activities or other operations may not comply with applicable laws resulting in civil or criminal proceedings. In addition, we could grant exclusive rights to our collaborators that would prevent us from collaborating with others. Collaborators may not properly maintain or defend our intellectual property rights or may use our intellectual property or proprietary information in a way that gives rise to actual or threatened litigation that could jeopardize or invalidate our intellectual property or proprietary information or expose us to potential liability. Our collaborators may own or co-own intellectual property covering products that result from our collaboration with them, depriving us of the exclusive right to develop or commercialize such intellectual property. Disputes may arise with respect to the ownership of any intellectual property developed pursuant to our collaborations. Disputes between us and a collaborator may delay or terminate the development or commercialization of our products or result in costly litigation or arbitration that diverts management attention and resources. Termination of a collaboration may also result in a need for additional capital to pursue further development of the applicable current or future products.

28 We may seek to enter into additional collaborations, joint ventures, licenses and other similar arrangements for the development of our products, due to capital costs required to develop the product or potential manufacturing constraints. We may not be successful in our efforts to establish such collaborations for our products because our products may be deemed to be at too early of a stage of development for collaborative effort or third parties may not view our products as having the requisite potential to demonstrate a significant commercial opportunity. In addition, we face significant competition in seeking appropriate strategic partners, and the negotiation process can be time consuming and complex. Further, any future collaboration agreements may restrict us from entering into additional agreements with potential collaborators. We cannot be certain that, following a strategic transaction or license, we will achieve an economic benefit that justifies such transaction. Even if we are successful in our efforts to establish such collaborations, the terms that we agree upon may not be favorable to us, and we may not be able to maintain such collaborations. In addition, any potential future collaborations may be terminable by our strategic partners, and we may not be able to adequately protect our rights under these agreements. Furthermore, strategic partners may negotiate for certain rights to control decisions regarding the development of our products, and may not conduct those activities in the same manner as we do. Any termination of collaborations we enter into in the future, or any delay in the development of products under such collaborations, could delay the manufacturing and sales of our products, which could have a material adverse effect on our business, financial condition and results of operations. We may become subject to product liability claims that may not be covered by insurance and could require us to pay substantial sums. We are subject to an inherent risk of, and adverse publicity associated with, product liability and other liability claims, whether or not such claims are valid. In addition, our customers are subject to product liability claims, and could seek contribution from us. A successful product liability claim or series of claims against us could adversely impact the specialty chemicals or closures industries, our reputation or our financial condition or results of operations. Product liability insurance may not be available to us on commercially acceptable terms, or at all. Even if such insurance is available, product liability or other claims may exceed our insurance coverage limits. A successful product liability claim that exceeds our insurance coverage limits, for which we are not otherwise indemnified, could require us to pay substantial sums and could harm our business, financial condition or results of operations.

29 Climate change may impact the availability of our facilities and, in addition, we may incur substantial costs to comply with climate change legislation and related regulatory initiatives. Changing weather patterns and the increase in frequency of severe storms such as hurricanes and tornadoes could cause disruptions or the complete loss of our facilities or delay the construction of future facilities. In addition, climate change concerns, and changes in the regulation of such concerns, including greenhouse gas emissions, could also subject us to additional costs and restrictions, including increased energy and raw materials costs which could negatively impact our financial condition and results of operations. Climate change may also negatively impact our labor force by, for example, reducing the hours during which construction or other outdoor work can be performed safely in extreme hit or under conditions of poor air quality. In addition, climate change may negatively impact the availability of our feedstock, for example, by increasing the prevalence of certain pests harmful to the growth or quality of the biomass we use in our processes to produce Furanic Intermediates. The effects of climate change can not only adversely impact our operations, but also that of our suppliers and customers, and can lead to increased regulations and changes in consumer preferences, which could adversely affect our business, results of operations and financial condition. Unfavorable global economic conditions could adversely affect our business, financial condition and results of operations. Our results of operations could be adversely affected by general conditions in the global economy and in the global financial markets, including inflation and supply disruption. A domestic or global financial crisis can cause extreme volatility and disruptions in the capital and credit markets. A severe or prolonged economic downturn, which could result from an event like the COVID-19 pandemic or the global sanctions imposed against Russia following its military intervention in Ukraine, or inflation in fuel costs resulting from regional instability due to the military conflict in Israel and Gaza, could result in a variety of risks to our business, including our inability to purchase necessary supplies on acceptable terms, if at all, and our inability to raise additional capital when needed on acceptable terms, if at all. A weak or declining economy could strain our suppliers, possibly resulting in supply disruption, or cause delays in payments for our services by third-party payers or our collaborators. Any of the foregoing could harm our business and we cannot anticipate all of the ways in which the current economic climate and financial market conditions could adversely impact our business. See also “Risks Related to Government Regulation.” Our operating results may fluctuate significantly as a result of a variety of factors, many of which are outside of our control. We are subject to, among other things, the following factors that may negatively affect our operating results: • the announcement or introduction of new products by our competitors; • our ability to upgrade and develop our systems and infrastructure to accommodate growth; • our ability to attract and retain key personnel in a timely and cost-effective manner; • our ability to attract new customers and retain existing customers; • technical difficulties; • the amount and timing of operating costs and capital expenditures relating to the expansion of our business, operations and infrastructure;

30 • our ability to identify and enter into relationships with appropriate and qualified third-party providers of necessary testing and manufacturing services; • regulation by federal, state or local governments; and • general economic conditions, as well as economic conditions specific to the closures industry, and the chemicals, plastics, carbon products, and fuels industries, and other industries related to compostable or biodegradable substitutes for non-biodegradable plastics, as well as changes to commodity prices to which prices in some of our contracts are indexed. As a result of our limited operating history and the nature of the markets in which we compete, it is difficult for us to forecast our revenues or earnings accurately. We have based our anticipated future expense levels largely on our investment plans and estimates of future events, although certain of our expense levels will, to a large extent, become fixed. As a strategic response to changes in the competitive environment, we may from time to time make certain decisions concerning expenditures, pricing, service or marketing that could harm our business, results of operations and financial condition. Due to the foregoing factors, our revenues and operating results are difficult to forecast. Changes in tax laws or tax rulings could materially affect our financial position, results of operations, and cash flows. The tax regimes we are subject to or operate under, including income and non-income taxes, are unsettled and may be subject to significant change. Changes in tax laws, regulations, or rulings, or changes in interpretations of existing laws and regulations, could materially affect our financial position and results of operations. For example, the 2017 Tax Cuts and Jobs Act (the “Tax Act”) made broad and complex changes to the U.S. tax code. Future guidance from the IRS with respect to the Tax Act may affect us, and certain aspects of the Tax Act could be repealed or modified in future legislation. The Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) has already modified certain provisions of the Tax Act. More recently, the Inflation Reduction Act of 2022 (the “IRA”) includes provisions that will impact the U.S. federal income taxation of corporations, including imposing a minimum tax on the book income of certain large corporations and an excise tax on certain corporate stock repurchases that would be imposed on the corporation repurchasing such stock. In addition, it is uncertain if and to what extent various states will conform to the Tax Act, the CARES Act, the IRA, or any newly enacted federal tax legislation. The issuance of additional regulatory or accounting guidance related to the Tax Act could materially affect our tax obligations and effective tax rate in the period issued. In addition, many countries in Europe and a number of other countries and organizations, have recently proposed or recommended changes to existing tax laws or have enacted new laws that could significantly increase our tax obligations in the countries where we do business or require it to change the manner in which we operate our business. The Organization for Economic Cooperation and Development has been working on a Base Erosion and Profit Shifting Project, and issued a report in 2015, an interim report in 2018, and is expected to continue to issue guidelines and proposals that may change various aspects of the existing framework under which our tax obligations are determined in many of the countries in which we do business. Similarly, the European Commission and several countries have issued proposals that would change various aspects of the current tax framework under which we are taxed. These proposals include changes to the existing framework to calculate income tax, as well as proposals to change or impose new types of non-income taxes, including taxes based on a percentage of revenue.

31 As we expand the scale of our international business activities, these types of changes to the taxation of our activities could increase our worldwide effective tax rate, increase the amount of taxes imposed on our business, and harm our financial position. Such changes may also apply retroactively to our historical operations and result in taxes greater than the amounts estimated and recorded in our financial statements. Unanticipated changes in effective tax rates or adverse outcomes resulting from examination of our income or other tax returns could adversely affect our operating results and financial condition. We are subject to taxation in Canada and the United States with increasingly complex tax laws, the application of which can be uncertain. The amount of taxes we pay in these jurisdictions could increase substantially as a result of changes in the applicable tax principles, including increased tax rates, new tax laws or revised interpretations of existing tax laws and precedents, which could have an adverse impact on our liquidity and results of operations. In addition, the authorities in several jurisdictions could review our tax returns and impose additional tax, interest and penalties, which could have an impact on us and on our results of operations. We have previously participated in government programs with the Canadian federal government and Canadian provincial governments that provide investment tax credits based upon qualifying research and development expenditures. If Canadian taxation authorities successfully challenge such expenses or the correctness of such income tax credits claimed, our historical operating results could be adversely affected. As a public company, we will no longer be eligible for refundable tax credits under the Canadian federal Scientific Research and Experimental Development Program credits. Our future effective tax rates could be subject to volatility or adversely affected by a number of factors. Our future effective tax rates could be subject to volatility or adversely affected by a number of factors, including: • changes in the valuation of our deferred tax assets and liabilities; • expected timing and amount of the release of any tax valuation allowances; • tax effects of stock-based compensation; • costs related to intercompany restructurings; • changes in tax laws, regulations or interpretations thereof; or • future earnings being lower than anticipated in countries where we have lower statutory tax rates and higher than anticipated earnings in countries where we have higher statutory tax rates. We may conduct activities in other jurisdictions through our subsidiaries pursuant to transfer pricing arrangements and may in the future conduct operations in other jurisdictions pursuant to similar arrangements. If two or more affiliated companies are located in different countries, the tax laws or regulations of each country generally will require that transfer prices be the same as those between unrelated companies dealing at arms’ length. While we intend to operate in compliance with applicable transfer pricing laws, our transfer pricing procedures are not binding on applicable tax authorities. If tax authorities in any of these countries were to successfully challenge our transfer prices as not reflecting arm’s length transactions, they could require us to adjust our transfer prices and thereby reallocate our income to reflect these revised transfer prices, which could result in a higher tax liability to us.

32 Our ability to use net operating loss carryforwards and other tax attributes may be limited in connection with the Merger or other ownership changes. We have incurred losses during our history. To the extent that we continue to generate taxable losses, unused losses will carry forward to offset future taxable income, if any, until such unused losses expire, if at all. Under the Tax Act, as modified by the CARES Act, U.S. federal NOL carryforwards generated in taxable periods beginning after December 31, 2017, may be carried forward indefinitely, but the deductibility of such net operating loss carryforwards in taxable years beginning after December 31, 2020, is limited to 80% of taxable income. In addition, our NOL carryforwards are subject to review and possible adjustment by the IRS, and state tax authorities. Under Sections 382 and 383 of the Code, our federal net operating loss carryforwards and other tax attributes may become subject to an annual limitation in the event of certain cumulative changes in the ownership of our stock. An “ownership change” pursuant to Section 382 of the Code generally occurs if one or more stockholders or groups of stockholders who own at least 5% of a company’s stock increase their ownership (as measured by value) by more than 50 percentage points over their lowest ownership percentage within a rolling three-year period. Our ability to utilize our NOL carryforwards and other tax attributes to offset future taxable income or tax liabilities may be limited as a result of ownership changes, including potential changes in connection with the Merger or other transactions. Similar rules may apply under state tax laws. We have recorded a valuation allowance related to the majority of our NOL carryforwards and other deferred tax assets due to the uncertainty of the ultimate realization of the future benefits of those assets. Risks Related to Government Regulation Compliance with extensive environmental, health and safety laws could require material expenditures, changes in our operations or site remediation. We use hazardous materials in our production process, and our operations also produce hazardous waste. The manufacture, transportation and sale of our products can present potentially significant health and safety concerns and are also under increased public and governmental scrutiny. Our products are also used in a variety of applications that have specific regulatory requirements such as those relating to products that have contact with food or are used for medical applications. Accordingly, our operations are subject to environmental, health and safety laws and regulations at the international, national, state and local level in multiple jurisdictions. These laws and regulations govern, among other things, air emissions, wastewater discharges, solid and hazardous waste management and disposal, occupational health and safety, including dust and noise control, site remediation programs and chemical use and management. Many of these laws and regulations have become more stringent over time and the costs of compliance with these requirements may increase, including costs associated with any necessary capital investments. In addition, our manufacturing facilities will require operating permits that are subject to renewal and, in some circumstances, revocation. The necessary permits may not be issued or continue in effect, and renewals of any issued permits may contain significant new requirements or restrictions. The nature of the specialty chemicals industry exposes us to risks of liability due to the use, production, management, storage, transportation and sale of materials that are heavily regulated or hazardous and can cause contamination or personal injury or damage if released into the environment. Compliance with environmental laws and regulations generally increases the costs of transportation and storage of raw materials and finished products, as well as the costs of storage and disposal of wastes. We may incur substantial costs, including fines, damages, criminal or civil sanctions and remediation costs, or experience

33 interruptions in our operations for violations arising under environmental laws, regulations or permit requirements. In addition, the market for bioplastics, and for plastic products like our PET closures generally, is heavily influenced by applicable federal, state and local government laws, regulations and policies, such as the European Union's Single-Use Plastic Directive, which came into effect in July 2024, and minimum recycled content requirements for beverage bottle packaging in the European Union, Peru, South Africa, and certain states in the United States, as well as public perception. Changes in these laws, regulations and policies or how these laws, regulations and policies are implemented and enforced could cause the demand for our products to decline and deter investment in the research and development of such product. Concerns associated with bioplastics, including land usage, national security interests, deforestation, food crop usage, and other environmental concerns with bioplastics as well as plastic products generally, continue to receive legislative, industry and public attention. This attention could result in future legislation, regulation and/or administrative action that could adversely affect our business. Furthermore, various petrochemical products, including plastics like PET used in our closures products, have faced increased public scrutiny due to negative coverage of plastic waste in the environment, which has resulted in local, state, federal and foreign governments proposing and in some cases approving, restrictions or bans on the manufacture, consumption and disposal of certain petrochemical products. Although our biomass-derived chemical products and materials made from them are intended to replace petrochemical products, increased regulation on the use of such products or other products in the specialty chemicals industry, whatever their scope or form, could increase our costs of production, impact overall consumption of our products or result in misdirected negative publicity. Any inability to address these requirements and any regulatory or policy changes could harm our business, financial condition and results of operations. We are subject to U.S. and foreign anti-corruption and anti-money laundering laws and regulations. We could face criminal liability and other serious consequences for violations, which would harm our business. We are subject to the U.S. Foreign Corrupt Practices Act of 1977, as amended, the U.S. domestic bribery statute contained in 18 U.S.C. § 201, the U.S. Travel Act, the USA PATRIOT Act and possibly other anti-bribery and anti-money laundering laws in countries in which we conduct activities. Anti-corruption laws are interpreted broadly and prohibit companies and their employees, agents, contractors and other collaborators from authorizing, promising, offering or providing, directly or indirectly, improper payments or anything else of value to recipients in the public or private sector. We can also be held liable for the corrupt or other illegal activities of our employees, agents, contractors and other collaborators, even if we do not explicitly authorize or have actual knowledge of such activities. Any violations of the laws and regulations described above may result in substantial civil and criminal fines and penalties, imprisonment, the loss of export or import privileges, debarment, tax reassessments, breach of contract and fraud litigation, reputational harm and other consequences. Our operating plan may require us to source feedstock and supplies internationally, and foreign currency exchange rate fluctuations and changes to international trade agreements, tariffs, import and excise duties, taxes or other governmental rules and regulations could adversely affect our business, financial condition, results of operations and prospects. Our expansion model is global and we expect to need to source feedstock and supplies from suppliers around the world. In particular, we expect to source PET, including recycled PET, from suppliers local to our closures manufacturing lines, or to arrange for transport of PET to the site of those lines. Similarly, our furanics chemical manufacturing process is designed to use local timber and forest residues as our primary raw materials, which

34 must be sourced locally. For the Origin 1 plant, this means we will need to source feedstock, as well as other supplies, from Canadian suppliers or arrange for transport of such feedstock and supplies into Canada. The U.S. federal government or other governmental bodies may propose changes to international trade agreements, tariffs, taxes and other government rules and regulations, and may impose sanctions limiting trade with other countries. If foreign currency exchange rates fluctuate or any restrictions or significant increases in costs or tariffs or sanctions are imposed related to feedstock and supplies sourced to our plants as a result of amendments to existing trade agreements or otherwise, this may increase our supply and shipping costs, resulting in potential decreased margins. We may expand our operations to countries with unstable governments that are subject to instability, corruption, changes in rules and regulations and other potential uncertainties that could harm our business, financial condition, results of operations and prospects. The extent to which our margins could decrease in response to any future tariffs is uncertain. We continue to evaluate the impact of trade agreements, as well as foreign currency exchange rate fluctuations and other recent changes in foreign trade policy on our supply chain, costs, sales and profitability. In addition, pandemics such as COVID-19 may result in increased travel restrictions and the extended shutdown of certain businesses throughout the world, and prolonged closures in Canada, Europe, Asia and elsewhere may disrupt the operations of certain suppliers of feedstock and other supplies, which could, in turn, negatively impact our business, financial condition, results of operations and prospects. International trade disputes and the U.S. government’s trade policy could adversely affect our business. International trade disputes could result in tariffs and other protectionist measures that could adversely affect our business. Tariffs could increase the cost of our products and the components and raw materials that go into making them. These increased costs could adversely impact the gross margin that we earn on our products. Countries may also adopt other protectionist measures that could limit our ability to offer our products. The U.S. government has indicated its intent to adopt a new approach to trade policy and in some cases to renegotiate, or potentially terminate, certain existing bilateral or multi-lateral trade agreements. It has also initiated tariffs on certain foreign goods and has raised the possibility of imposing significant, additional tariff increases or expanding the tariffs to capture other types of goods. Although the tariffs that have been initiated to date have not had a material impact on our operating results, to the extent that significant additional tariffs are imposed, depending on the extent of such tariffs, they could have a material impact on our operating results. For example, the President indicated during his campaign that he would seek to impose a 25% tariff against all goods imported from Canada and Mexico, a 60% tariff on goods from China and a blank tariff of 10% to 20% on other imports to the U.S. On February 1, 2025, the President issued an Executive Order imposing tariffs on imports from Canada, Mexico, and China. The newly imposed tariffs have resulted in immediate threats of retaliatory tariffs against U.S. goods, some of which have now come into effect. These and other potential tariffs and trade restrictions may increase the prices of our products or those of our customers with which our products are used. This, in turn, could reduce demand for such products, or reduce our, or our customers’ margins, and adversely impact our, or their revenues, financial results, and ability to service debt. We import many components for our CapFormer systems from countries in Europe and a 10% to 20% tariff on imports of such components would increase the cost of CapFormers, adversely impacting our business, results of operations, financial condition and cash flows. Similarly, we currently have manufacturing operations in Canada to produce Furanic Intermediates, a 25% tariff on all imports from Canada would increase the cost of our Furanic Intermediates manufactured in Canada, which could and adversely impact our business, results of operations, financial condition and cash flows.

35 We cannot predict the extent to which the United States or other countries will impose quotas, duties, tariffs, taxes or other similar restrictions upon the import or export of our products in the future, nor can we predict future trade policy or the terms of any renegotiated trade agreements and their impact on our business. The adoption and expansion of trade restrictions, the occurrence of a trade war, or other governmental action related to tariffs or trade agreements or policies has the potential to adversely impact demand for our products, our costs, our consumers, our suppliers, and the U.S. economy, which in turn could have an adverse effect on our business, financial condition, results of operations and prospects. We are subject to ESG risks, including in relation to our counterparties, which may adversely affect our reputation and ability to retain employees and customers. Companies across many industries are facing increasing scrutiny related to their environmental, social and governance (ESG) practices and reporting, both in the United States and internationally, including risks related to climate, workforce and other sensitive matters., To the extent we share information about our ESG practices, we could be criticized for the accuracy, adequacy, or completeness of such disclosures. Further, we may experience backlash from customers, government entities, advocacy groups, employees, or other stakeholders who disagree with our actual or perceived positions, or with our lack of position on social, environmental, governance, political, public policy, economic, geopolitical, or other sensitive issues. Any perceived lack of transparency about these matters could harm our brand and reputation, our employees’ engagement and retention, and the willingness of our customers and partners to do business with us. We may be exposed to negative publicity based on the identity and activities of our customers and others with whom we do business, and the public’s view of our customers' and business partners' approach to ESG matters. Our management may incur additional costs and need to dedicate increased of time and attention to ESG matters and to comply with a rapidly changing landscape of regulations and expectations. For example, the President has recently issued an Executive Order mandating the United States' withdrawal from the Paris Agreement, and other climate-focused international agreements and commitments. Some states also have introduced or passed bills to restrict, regulate, or prohibit DEI initiatives. Our failure to comply with any applicable rules or regulations with respect to ESG matters could lead to penalties and adversely impact our access to capital and employee retention, and could impact third parties on whom we rely, adversely affecting our business, financial condition, or results of operations. For example, if our customers back away from carbon emission reduction or other sustainability goals in response to the President's Executive Orders, demand for our products may decline because environmental and sustainability benefits are part of the value proposition of those products. A decline in the value of carbon credits associated with our products, if any, could harm our results of operations, cash flow and financial condition. The value of our products may be dependent on the value of carbon credits, programs relating to low-carbon materials and products standards and other similar regulatory regimes or the implicit value of decarbonized materials. The value of these credits fluctuates based on market and regulatory forces outside of our control. There is a risk that the supply of low-carbon alternative materials and products outstrips demand, resulting in the value of carbon credits declining. Any such declines could mean that the economic benefits from our customers’ efforts to decarbonize their operations might not be realized. Any decline in the value of carbon credits associated with our products could harm our results of operations, cash flow and financial condition.

36 Risks Related to Our Intellectual Property Our business relies on proprietary information and other intellectual property, and our failure to protect our intellectual property rights could harm our competitive advantages with respect to the use, manufacturing, sale or other commercialization of our processes, technologies and products, which may have an adverse effect on our results of operations and financial condition. We intend to make significant capital investments into the research and development of proprietary information and other intellectual property as we develop, improve and scale our processes, technologies and products, and failure to fund and make these investments, or underperformance of the technology funded by these investments, could severely impact our business, financial condition, results of operations and prospects. If we fail to adequately protect our intellectual property rights, such failure could result in the reduction or loss of our competitive advantage. We may be unable to prevent third parties from using our proprietary information and other intellectual property without our authorization or from independently developing proprietary information and other intellectual property that is similar to ours, particularly in those countries where the laws do not protect our proprietary rights to the same degree as in the U.S or those countries where we do not have intellectual property rights protection. Some of our vendors have filed, and may in the future file, patent applications claiming intellectual property that we contend belongs to us. In some cases, we have been able to resolve disputes over such intellectual property amicably and in a manner that we believe will be beneficial to our business. There can be no guarantee we will be able to reach an amicable resolution of all such disputes or that the resolution, if any, will in fact be beneficial to our business. In some cases, litigation or arbitration may be necessary to resolve disputes over intellectual property, and we might be unable to continue working with vendors and other parties as a result of such disputes, all of which could cause significant cost and disruption to our business and fail to vindicate our claims to the intellectual property. The use of our proprietary information and other intellectual property by others could reduce or eliminate competitive advantages that we have developed, potentially causing us to lose sales or actual or potential customers, or otherwise harm our business. We have been, and may again be, involved in litigation and administrative actions to protect these rights, and such proceedings could be burdensome and costly, could result in counterclaims challenging our intellectual property (including validity or enforceability) or accusing us of infringement, and we may not prevail. Our patent applications and issued patents may be practiced by third parties without our knowledge. Our competitors may also attempt to design around our patents or copy or otherwise obtain and use our proprietary information and other intellectual property. Moreover, our competitors may already hold or have applied for patents in the U.S. or abroad that, if enforced, could possibly prevail over our patent rights or otherwise limit our ability to manufacture, sell or otherwise commercialize one or more of our products in the U.S. or abroad. With respect to our pending patent applications, we may not be successful in securing issued patents, or the claims of such patents may be narrowed, any of which may limit our ability to protect inventions that these applications were intended to cover, which could harm our ability to prevent others from exploiting our technologies and commercializing products similar to our products. In addition, the expiration of a patent can result in increased competition with consequent erosion of profit margins.

37 The applicable governmental authorities may not approve our pending service mark and trademark applications. A failure to obtain trademark registrations in the U.S. and in other countries could limit our ability to obtain and retain our trademarks in those jurisdictions. Moreover, third parties may seek to oppose our applications or otherwise challenge the resulting registrations. In the event that our trademarks are not approved or are successfully challenged by third parties, we could be forced to rebrand our products, which could result in loss of brand recognition and could require us to devote significant resources to rebranding and advertising and marketing new brands. The failure of our patents, trademarks, trade secrets, or confidentiality agreements to protect our proprietary information and other intellectual property, including our processes, apparatuses, technology, trade secrets, trade names and proprietary manufacturing expertise, methods and compounds, could have a material adverse effect on our business and results of operations. Some of our intellectual property has been or will be discovered, conceived or developed through research funded by the Canadian government and thus may be subject to federal regulations providing for certain rights for the Canadian government or imposing certain obligations on us, such as limitations on exploiting such intellectual property outside of Canada. Compliance with such regulations may limit our exclusive rights and ability to commercialize our products and technology outside of Canada. We may face patent infringement and other intellectual property claims that could be costly to defend, result in injunctions and significant damage awards or other costs (including indemnification of third parties or costly licensing arrangements, if licenses are available at all) and limit our ability to use certain key technologies in the future or require development of non-infringing products or technologies, which may cause us to incur significant unexpected costs, prevent us from commercializing our products and otherwise harm our business. The various markets in which we plan to operate are subject to frequent and extensive litigation regarding patents, trade secrets and other intellectual property rights. Many of our competitors have a substantial amount of intellectual property. We cannot guarantee that our processes and products do not and will not infringe issued patents (whether present or future) or other intellectual property rights belonging to others. From time to time, we may oppose third-party patents that we consider overbroad or otherwise invalid in order to maintain the necessary freedom to operate fully in our various business lines without the risk of being sued for patent infringement. If, however, the oppositions are unsuccessful, we could be liable for infringement or have to take other remedial or curative actions to continue our manufacturing and sales activities with respect to one or more products. We may also be subject to legal proceedings and claims in the ordinary course of our business, including claims of alleged infringement or misappropriation of the patents, trademarks, trade secrets and other intellectual property rights of third parties by us or our licensees in connection with their use of our products. Intellectual property litigation is expensive and time-consuming, regardless of the merits of any claim, and could divert our management’s attention from operating our business.

38 If we were to discover that our processes, technologies or products infringe or misappropriate the valid intellectual property rights of others, we might need to obtain licenses from these parties or substantially re-engineer our processes, technologies or products in order to avoid infringement. We may not be able to obtain the necessary licenses on acceptable terms, or at all, or be able to re-engineer our processes, technologies or products successfully. Moreover, if we or our licensees are sued for infringement or misappropriation and lose, we could be required to pay substantial damages, indemnify our licensees and/or be enjoined from using or selling the infringing processes, technologies or products. If we incur significant costs to litigate infringement or misappropriation claims or to obtain licenses, or if our inability to obtain required licenses prevents us from using or selling our processes, technologies or products, it could have a material adverse effect on our business and results of operations. We rely on trade secrets to protect our technology, and our failure to maintain trade secret protection could limit our ability to compete. We rely on trade secrets to protect some of our technology and proprietary information, especially where we believe patent protection is not appropriate or obtainable. We have security measures in place to safeguard our trade secrets database and limit the access to a need-to-know basis. However, trade secrets can be difficult to protect. The misappropriation or other compromise of our trade secrets may lead to a reduction or loss of our competitive advantages resulting from such trade secrets. Further, litigating a claim that a third party had misappropriated our trade secrets would be expensive and time consuming, and the outcome would be unpredictable. Moreover, if our competitors independently develop similar knowledge, methods and know-how, it will be difficult for us to enforce our rights and our business could be harmed. Our confidentiality agreements could be breached or may not provide meaningful protection for our trade secrets or proprietary manufacturing expertise. Adequate remedies may not be available in the event of an unauthorized use or disclosure of our trade secrets and manufacturing expertise. Violations by others of our confidentiality agreements and the loss of employees who have specialized knowledge and expertise could harm our competitive position resulting from the exclusive nature of such knowledge and expertise and cause our sales and operating results to decline as a result of increased competition. In addition, others may obtain knowledge of our trade secrets through independent development or other access by legal means. Other Risks Related to Our Business Our management team has relatively limited experience in operating a public company. Many of our executive officers have limited experience in the management of a publicly traded company subject to significant regulatory oversight and reporting obligations under federal securities laws. We may not have adequate personnel with the appropriate level of knowledge, experience and training in the accounting policies, practices or internal control over financial reporting required of public companies in the United States. It is possible that we will be required to expand our employee base and hire additional employees to support our operations as a public company, which will increase our operating costs in future periods.

39 We are dependent on management and key personnel, and our business could suffer if we fail to retain our key personnel or attract additional highly skilled employees. Our success depends on the specialized skills of our management team and key operating personnel. This may present particular challenges as we operate in a highly specialized industry sector, which may make replacement of our management team and key operating personnel difficult. A loss of our managers or key employees, or their failure to satisfactorily perform their responsibilities, could have an adverse effect on our business, financial condition, results of operations and prospects. For example, our former co-Chief Executive Officer, Rich Riley, resigned from his position effective December 31, 2024. Our future success will depend on our ability to identify, hire, develop, motivate and retain highly qualified personnel for all areas of our organization, particularly research and development, engineering, operations, and sales. Trained and experienced personnel are in high demand and may be in short supply. Many of the companies that we compete with for experienced employees have greater resources than us and may be able to offer more attractive terms of employment. In addition, we invest significant time and expense in training employees, which increases their value to competitors that may seek to recruit them. We may not be able to attract, develop and maintain the skilled workforce necessary to operate our business, and labor expenses may increase as a result of a shortage in the supply of qualified personnel, which could negatively impact our business, financial condition, results of operations and prospects. We may not realize the expected benefits from our recent workforce reduction, and it could result in total costs and expenses that are greater than expected and could disrupt our business. In September 2024, we implemented a reduction in our workforce. We may incur additional expenses not currently contemplated due to events associated with the reduction in force, and our restructuring activities may subject us to reputational risks and litigation risks and expenses. We may not fully realize the anticipated benefits and savings from this operational realignment due to unforeseen difficulties, disruptions, delays or unexpected costs, which could adversely affect our financial condition. The changes to our operations and the reduction in workforce may yield unintended consequences and costs, such as the loss of institutional knowledge and expertise, attrition beyond our intended reductions in force, and a reduction in morale among our remaining employees, all of which may have an adverse effect on our development activities, our business, results of operations or financial condition. If we are unable to realize the expected operational efficiencies, our business, results of operations and financial condition would be adversely affected. In addition, to the extent we do not realize such anticipated operational efficiencies, we may need to undertake workforce reductions or restructuring activities in the future. Furthermore, our reductions in force may be disruptive to our operations. If employees who were not affected by the reductions in force seek alternative employment, this could result in our seeking contractor support at unplanned additional expense or harm our productivity. Our workforce reductions could also harm our ability to attract and retain qualified management, technical and manufacturing personnel who are critical to our business. Any failure to attract or retain qualified personnel could prevent us from successfully developing our products. We may also discover that the reductions in workforce could make it difficult for us to pursue new opportunities and initiatives and require us to hire qualified replacement personnel, which may require us to incur additional and unanticipated costs and expenses. Our failure to successfully accomplish any of the above activities and goals may have a material adverse impact on our business, results of operations and financial condition. We previously identified a material weakness in our internal control over financial reporting that we have

40 concluded has been remediated. However, we may identify additional material weaknesses in the future or fail to maintain effective internal control over financial reporting, which may result in material misstatements of our consolidated financial statements or cause us to fail to meet our periodic reporting obligations. In connection with the audit of our consolidated financial statements for the fiscal years ended December 31, 2019 and December 31, 2020, during the course of preparing for the Merger, and during the second quarter 2021 and third quarter 2021 interim reviews, we identified a material weakness in our internal control over financial reporting. We implemented and continue to employ measures designed to improve our internal control over financial reporting, which remediated this material weakness in the fourth quarter of 2021. A material weakness is a deficiency, or a combination of deficiencies, in internal control over financial reporting such that there is a reasonable possibility that a material misstatement of its annual or interim financial statements will not be prevented or detected on a timely basis. If we are unable to successfully remediate any future material weaknesses in our internal control over financial reporting, or if we identify any additional material weaknesses, the accuracy and timing of our financial reporting may be adversely affected, we may be unable to maintain compliance with securities law requirements regarding timely filing of periodic reports in addition to applicable Nasdaq listing requirements, investors may lose confidence in our financial reporting and our stock price may decline as a result. We also could become subject to investigations by Nasdaq, the SEC or other regulatory authorities. As a public company, we are also required, pursuant to Section 404 of the Sarbanes-Oxley Act, to furnish a report by management on, among other things, the effectiveness of its internal control over financial reporting for our annual reports on Form 10-K to be filed with the SEC. This assessment needs to include disclosure of any material weaknesses identified by management in our internal control over financial reporting. We are required to disclose changes made in our internal control over financial reporting on a quarterly basis. Failure to comply with the Sarbanes-Oxley Act could potentially subject us to sanctions or investigations by the SEC, the applicable stock exchange or other regulatory authorities, which would require additional financial and management resources. In order to evaluate the effectiveness of internal control over financial reporting, as required by Section 404 of the Sarbanes-Oxley Act, management has conducted an assessment, including testing, using the criteria in Internal Control – Integrated Framework, issued by the Committee of Sponsoring Organizations of the Treadway Commission using the 2013 framework. Our system of internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of financial statements for external purposes in accordance with generally accepted accounting principles. Because of its inherent limitations, internal control over financial reporting may not prevent or detect all misstatements.

41 We and the third parties with whom we work are subject to stringent and changing U.S. and foreign laws, regulations, rules, contractual obligations, policies and other obligations related to data privacy and security. Our (or the third parties with whom we work) actual or perceived failure to comply with such obligations could lead to regulatory investigations or actions; litigation (including class action claims) and mass arbitration demands; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers or sales; and other adverse business consequences. In the ordinary course of business, we collect, receive, store, process, generate, use, transfer, disclose, make accessible, protect, secure, dispose of, transmit, and share (commonly known as processing) personal data and other sensitive information, including proprietary and confidential business data, trade secrets, and intellectual property. Our data processing activities subject us to various data privacy and security obligations, which can include laws, regulations, guidance, industry standards, external and internal privacy and security policies, contracts, and other obligations that govern the processing of personal data by us and on our behalf. In the United States, federal, state, and local governments have enacted numerous data privacy and security laws, including data breach notification laws, personal data privacy laws, and consumer protection laws (e.g., Section 5 of the Federal Trade Commission Act), and other similar laws (e.g., wiretapping laws). Numerous U.S. states have enacted comprehensive privacy laws that impose certain obligations on covered businesses, including providing specific disclosures in privacy notices and affording residents with certain rights concerning their personal data. Certain states also impose stricter requirements for processing certain personal data, including sensitive information, such as conducting data privacy impact assessments. For example, the California Consumer Privacy Act of 2018 (“CCPA”) imposes obligations on businesses to which it applies, such as providing specific disclosures in privacy notices and affording California residents certain rights related to their personal data. The CCPA also applies to personal data of consumers, business representatives, and employees who are California residents and provides for fines and allows private litigants affected by certain data breaches to recover significant statutory damages. In addition, the California Privacy Rights Act of 2020 (“CPRA”), expanded the CCPA, including by establishing a California Privacy Protection Agency to implement and enforce the CPRA. Similar laws are being considered in several other states, as well as the federal, state, and local levels in recent years, which could further complicate compliance efforts. Outside the United States, an increasing number of laws, regulations, and industry standards apply to data privacy and security. For example, the European Union’s General Data Protection Regulation (“EU GDPR”) and the United Kingdom’s GDPR (“UK GDPR”) impose strict requirements for processing the personal data of individuals located in the European Economic Area and the UK, respectively. For example, under the EU GDPR, government regulators may impose temporary or definitive bans on data processing, as well as fines of up to €20 million or 4% of annual global revenue, whichever is greater. The GDPR also allows for private litigation related to processing of personal data brought by classes of data subjects or consumer protection organizations authorized at law to represent their interests. Additionally, in Canada, the Personal Information Protection and Electronic Documents Act and various related provincial laws, as well as Canada’s Anti-Spam Legislation, apply to our operations. We also have customers in Asia, and may be subject to new and emerging data privacy regimes in Asia, such as China’s Personal Information Protection Law and Japan’s Act on the Protection of Personal Information. In addition, certain jurisdictions have enacted data localization laws and cross-border personal data transfer laws, which could make it more difficult to transfer information across jurisdictions (such as transferring or receiving personal data that originates in Europe or other jurisdictions). Existing mechanisms that may facilitate cross- border personal data transfers may change or be invalidated. Regulators in the United States such as the Department of Justice are also increasingly scrutinizing certain personal data transfers and have proposed and

42 enacted data localization requirements, for example, the Biden Administration’s executive order Preventing Access to Americans’ Bulk Sensitive Personal Data and United States Government-Related Data by Countries of Concern. We are also bound by contractual obligations related to data privacy and security, and our efforts to comply with such obligations may not be successful. We publish privacy policies, marketing materials, white papers, and other statements, such as statements related to compliance with certain certifications or self-regulatory principles, concerning data privacy and security. Regulators in the United States are increasingly scrutinizing these statements, and if these policies, materials or statements are found to be deficient, lacking in transparency, deceptive, unfair, misleading, or misrepresentative of our practices, we may be subject to investigation, enforcement actions by regulators or other adverse consequences. Obligations related to data privacy and security (and consumers' data privacy expectations) are quickly changing becoming increasingly stringent and creating uncertainty. Additionally, these obligations may be subject to differing applications and interpretations, which may be inconsistent or in conflict among jurisdictions. Preparing for and complying with these obligations requires us to devote significant resources (including, without limitation, financial and time-related resources). These obligations may necessitate changes to our information technologies, systems, and practices and to those of any third parties that process personal data on our behalf. In addition, these obligations may require us to change our business model. Although we endeavor to comply with all applicable data privacy and security obligations, we may at times fail (or be perceived to have failed) to do so. Moreover, despite our efforts, our personnel or third parties with whom we work may fail to comply with such obligations, which could negatively impact our business operations and compliance posture. For example, any failure by a third-party processor to comply with applicable law, regulations, or contractual obligations could result in material adverse effects, including inability to or interruptions in our ability to operate our business and proceedings against us by governmental entities or others. If we or the third parties with whom we work fail, or are perceived to have failed, to address or comply with data privacy and security obligations, we could face significant consequences. These consequences may include, but are not limited to, government enforcement actions (e.g., investigations, fines, penalties, audits, inspections, and similar); litigation (including class-related claims); additional reporting requirements and/or oversight; bans on processing personal data; and orders to destroy or not use personal data. Any of these events could have a material adverse effect on our reputation, business, or financial condition, including but not limited to: loss of customers; interruptions or stoppages in our business operations; inability to process personal data or to operate in certain jurisdictions; limited ability to develop or commercialize our products; expenditure of time and resources to defend any claim or inquiry; adverse publicity; or revision or restructuring of our operations. If our information technology systems or data, or those of third parties with whom we work, are or were compromised, we could experience adverse consequences resulting from such compromise, including but not limited to regulatory investigations or actions; litigation; fines and penalties; disruptions of our business operations; reputational harm; loss of revenue or profits; loss of customers; and other adverse consequences. In the ordinary course of our business, we and the third parties with whom we work process proprietary, confidential, and sensitive data, including personal data, intellectual property, and trade secrets (collectively, sensitive information).

43 Cyberattacks, malicious internet-based activity, and online and offline fraud are prevalent and continue to increase. These threats are becoming increasingly difficult to detect and come from a variety of sources, including traditional computer “hackers,” threat actors, personnel (such as through theft or misuse), sophisticated nation- states, and nation-state-supported actors. Some actors now engage and are expected to continue to engage in cyber-attacks, including without limitation nation-state actors for geopolitical reasons and in conjunction with military conflicts and defense activities. During times of war and other major conflicts, we and the third parties with whom we work may be vulnerable to a heightened risk of these attacks, including retaliatory cyber-attacks, that could materially disrupt our systems and operations, supply chain, and ability to produce, sell and distribute our products. We and the third parties with whom we work are subject to a variety of evolving threats, including but not limited to social-engineering attacks (including through deep fakes, which may be increasingly more difficult to identify as fake, and phishing attacks), malicious code (such as viruses and worms), malware (including as a result of advanced persistent threat intrusions), denial-of-service attacks credential stuffing, credential harvesting, personnel misconduct or error, ransomware attacks, supply-chain attacks, software bugs, server malfunctions, software or hardware failures, loss of data or other information technology assets, adware, telecommunications failures, earthquakes, fires, floods, attacks enhanced or facilitated by AI and other similar threats. Ransomware attacks, including those perpetrated by organized criminal threat actors, nation-states, and nation- state-supported actors, are becoming increasingly prevalent and severe – particularly for companies like ours that are engaged in manufacturing – and can lead to significant interruptions in our operations, loss of data and income, reputational harm, and diversion of funds. Extortion payments may alleviate the negative impact of a ransomware attack, but we may be unwilling or unable to make such payments due to, for example, applicable laws or regulations prohibiting such payments. Additionally, remote work has increased risks to our information technology systems and data, as our employees utilize network connections, computers and devices outside our premises or network, including working at home, while in transit and in public locations. Future or past business transactions (such as acquisitions or integrations) could also expose us to additional cybersecurity risks and vulnerabilities, as our systems could be negatively affected by vulnerabilities present in acquired or integrated entities’ systems and technologies. A security incident or other interruption could result in unauthorized, unlawful, or accidental acquisition, modification, destruction, loss, alteration, encryption, disclosure of, or access to our sensitive information. A security incident or other interruption could disrupt our ability (and that of third parties with whom we work) to provide our products. Furthermore, we may discover security issues that were not found during due diligence of such acquired or integrated entities, and it may be difficult to integrate companies into our information technology environment and security program. We rely on third-parties to operate critical business systems to process sensitive information in a variety of contexts, including, without limitation, third-party providers of cloud-based infrastructure, encryption and authentication technology, employee email, content delivery to customers, manufacturing processing, process orders and invoices, payments, inventory management and other functions. We also depend on these systems to respond to customer inquiries, support our overall internal control process, maintain property, plant and equipment records, and pay amounts due to vendors and other creditors. Our ability to monitor these third parties’ information security practices is limited, and these third parties may not have adequate information security measures in place. While we may be entitled to damages if a third party with whom we work fails to satisfy their privacy or security- related obligations to us, any award may be insufficient to cover our damages, or we may be unable to recover such award. In addition, supply-chain attacks have increased in frequency and severity, and we cannot guarantee that third parties’ infrastructure in our supply chain or that the third-parties with whom we work have not been compromised. We may share or receive sensitive information with or from third parties.

44 We may expend significant resources or modify our business activities in an effort to protect against security incidents. Certain data privacy and security obligations have required us to implement and maintain specific security measures, industry-standard or reasonable security measures to protect our information technology systems and sensitive information. While we have implemented security measures designed to protect against security incidents, there can be no assurance that these measures will be effective. We take steps to detect and remediate vulnerabilities in our information systems (such as our hardware and/or software, including that of third parties with whom we work). However, we may not be able to detect and remediate all vulnerabilities, including in a timely basis. Therefore, such vulnerabilities could be exploited and result in a security incident. These vulnerabilities pose material risks to our business. Despite our efforts to identify and remediate vulnerabilities, if any, in our information technology systems, our efforts may not be successful. Further, we may experience delays in developing and deploying remedial measures designed to address any such identified vulnerabilities. Applicable data privacy and security obligations may require us, or we may choose, to notify relevant stakeholders including affected individuals, customers, regulators, and investors, of security incidents or to take other actions, such as providing credit monitoring and identity theft protection services. Such disclosures and related actions are costly, and the disclosures or the failure to comply with such requirements could lead to adverse consequences. If we (or third parties with whom we work) experience a security incident or are perceived to have experienced a security incident, we may experience adverse consequences. These consequences may include: government enforcement actions (for example, investigations, fines, penalties, audits, and inspections); additional reporting requirements and/or oversight; restrictions on processing data (including personal data); litigation (including class-action claims); indemnification obligations; negative publicity; reputational harm; monetary fund diversions; interruptions in our operations (including availability of data); financial loss; and other similar harms. Security incidents and attendant material consequences may negatively impact our ability to grow and operate our business. Our contracts may not contain limitations of liability, and even where they do, there can be no assurance that limitations of liability in our contracts are sufficient to protect us from liabilities, damages, or claims related to our data privacy and security obligations. We cannot be sure that our insurance coverage will be adequate or sufficient to protect us from or to mitigate liabilities arising out of our data privacy and security practices, that such coverage will continue to be available on commercially reasonable terms or at all, or that such coverage will pay future claims. In addition to experiencing a security incident, third parties may gather, collect, or infer sensitive information about us from public sources, data brokers, or other means that reveals competitively sensitive details about our organization and could be used to undermine our competitive advantage or market position. Risks Related to Ownership of Our Shares Our Certificate of Incorporation provides, subject to limited exceptions, that the Delaware Court of Chancery is the sole and exclusive forum for certain stockholder litigation matters, which could limit our stockholders’ ability to obtain a chosen judicial forum for disputes with us or our directors, officers, employees or stockholders. Our Certificate of Incorporation requires, to the fullest extent permitted by law, that derivative actions brought in our name, actions against directors, officers and employees for breach of fiduciary duty and other similar actions may be brought in the Delaware Court of Chancery or, if that court lacks subject matter jurisdiction, another

45 federal or state court situated in the State of Delaware. Any person or entity purchasing or otherwise acquiring any interest in shares of our capital stock shall be deemed to have notice of and consented to the forum provisions in our Certificate of Incorporation. In addition, our Certificate of Incorporation provides that the federal district courts of the United States shall be the exclusive forum for the resolution of any complaint asserting a cause of action under the Securities Act. This choice of forum provision may limit a stockholder’s ability to bring a claim in a judicial forum of its choosing for disputes with us or any of our directors, officers, other employees or stockholders, which may discourage lawsuits with respect to such claims. Alternatively, if a court were to find the choice of forum provision contained in our Certificate of Incorporation to be inapplicable or unenforceable in an action, we may incur additional costs associated with resolving such action in other jurisdictions, which could harm our business, operating results and financial condition. Our charter documents and Delaware law could prevent a takeover that stockholders consider favorable and could also reduce the market price of our stock. Our Certificate of Incorporation and Bylaws contain provisions that could delay or prevent a change in control of us. These provisions could also make it more difficult for stockholders to elect directors and take other corporate actions. These provisions include: • initially providing for a classified Board with staggered, three-year terms; • authorizing our Board to issue Preferred Stock with voting or other rights or preferences that could discourage a takeover attempt or delay changes in control; • prohibiting cumulative voting in the election of directors; • providing that vacancies on our Board may generally be filled only by a majority of directors then in office, even though less than a quorum; • prohibiting the adoption, amendment or repeal of the Bylaws or the repeal of the provisions of our Certificate of Incorporation regarding the election and removal of directors without the required approval of at least two-thirds of the shares entitled to vote at an election of directors; • prohibiting stockholder action by written consent; • limiting the persons who may call special meetings of stockholders; and • requiring advance notification of stockholder nominations and proposals. These provisions may frustrate or prevent any attempts by our stockholders to replace or remove our current management by making it more difficult for stockholders to replace members of our Board, which is responsible for appointing the members of our management. In addition, the provisions of Section 203 of the General Corporation Law of the State of Delaware (“DGCL”) will govern us. These provisions may prohibit large stockholders, in particular those owning 15% or more of our outstanding voting stock, from merging or combining with us for a certain period of time without the consent of our Board. These and other provisions in our Certificate of Incorporation and our Bylaws under Delaware law could discourage potential takeover attempts, reduce the price investors might be willing to pay in the future for shares of our Common Stock and result in the market price of our Common Stock being lower than it would be without these provisions.

46 Claims for indemnification by our directors and officers may reduce our available funds to satisfy successful third-party claims against us and may reduce the amount of money available to us. Our Certificate of Incorporation and Bylaws provide that we will indemnify our directors and officers, in each case to the fullest extent permitted by Delaware law. In addition, as permitted by Section 145 of the DGCL, the Bylaws and its indemnification agreements that we entered into with our directors and officers provide that: • we will indemnify our directors and officers for serving us in those capacities or for serving other business enterprises at our request, to the fullest extent permitted by Delaware law. Delaware law provides that a corporation may indemnify such person if such person acted in good faith and in a manner such person reasonably believed to be in or not opposed to the best interests of the registrant and, with respect to any criminal proceeding, had no reasonable cause to believe such person’s conduct was unlawful; • we may, in our discretion, indemnify employees and agents in those circumstances where indemnification is permitted by applicable law; • we will be required to advance expenses, as incurred, to our directors and officers in connection with defending a proceeding, except that such directors or officers shall undertake to repay such advances if it is ultimately determined that such person is not entitled to indemnification; • we will not be obligated pursuant to our Bylaws to indemnify a person with respect to proceedings initiated by that person against us or our other indemnities, except with respect to proceedings authorized by our Board or brought to enforce a right to indemnification; • the rights conferred in the Bylaws are not exclusive, and we are authorized to enter into indemnification agreements with our directors, officers, employees and agents and to obtain insurance to indemnify such persons; and • we may not retroactively amend our Bylaw provisions to reduce our indemnification obligations to directors, officers, employees and agents. We do not intend to pay dividends for the foreseeable future. We have has never declared or paid any cash dividends on our capital stock and do not intend to pay any cash dividends in the foreseeable future. We expect to retain future earnings, if any, to fund the development and growth of our business. Any future determination to pay dividends on our capital stock will be at the discretion of our Board. In addition, our loan agreements contain restrictions on our ability to pay dividends. The market price and trading volume of our Common Stock has been and may be volatile and could decline significantly. The stock markets, including Nasdaq on which we have listed the shares of our Common Stock under the symbol “ORGN,” have from time to time experienced significant price and volume fluctuations. Even if an active, liquid and orderly trading market is sustained for our Common Stock, the market price of our Common Stock has been and may be volatile and could decline significantly. Our Common Stock experienced such a decline in August 2023. In addition, the trading volume in our Common Stock may fluctuate and cause significant price variations to occur. If the market price of our Common Stock declines significantly, you may be unable to resell your shares

47 at or above the market price of our Common Stock at which you purchased our Common Stock. We cannot assure you that the market price of Common Stock will not fluctuate widely or decline significantly in the future in response to a number of factors, including, among others, the following: • the realization of any of the risk factors presented in this Report; • actual or anticipated differences in our estimates, or in the estimates of analysts, for our revenues, results of operations, level of indebtedness, liquidity or financial condition; • additions and departures of key personnel; • failure to comply with the requirements of Nasdaq; • failure to comply with the Sarbanes-Oxley Act or other laws or regulations; • future issuances, sales, resales or repurchases or anticipated issuances, sales, resales or repurchases, of our securities; • publication of research reports about us; • the performance and market valuations of other similar companies; • commencement of, or involvement in, litigation involving us; • broad disruptions in the financial markets, including sudden disruptions in the credit markets; • speculation in the press or investment community; • actual, potential or perceived control, accounting or reporting problems; • changes in accounting principles, policies and guidelines; and • other events or factors, including those resulting from infectious diseases, health epidemics and pandemics, natural disasters, war, acts of terrorism or responses to these events. In the past, securities class-action litigation has often been instituted against companies following periods of volatility in the market price of their shares. This type of litigation could result in substantial costs and divert our management’s attention and resources, which could have a material adverse effect on us. In addition, litigation, including securities class action litigation, has often followed announcements of significant business transactions, such as the sale of a company or announcement of any other strategic transaction, or the announcement of negative events, such as negative earnings results. We are, and may in the future be, the target of this type of litigation. These events may also result in investigations by the Securities and Exchange Commission. Our quarterly operating results may fluctuate significantly and could fall below the expectations of securities analysts and investors due to seasonality and other factors, some of which are beyond our control, resulting in a decline in our stock price. Our quarterly operating results may fluctuate significantly because of several factors, including: • labor availability and costs for hourly and management personnel; • profitability of our products; • changes in interest rates;

48 • impairment of long-lived assets; • macroeconomic conditions, such as inflation and increasing interest rates, which may increase the risk of a potential recession; • negative publicity relating to products we serve; • changes in consumer preferences and competitive conditions; • expansion to new markets; and • fluctuations in commodity prices. If securities or industry analysts do not publish or cease publishing research or reports about us, our business, or our market, or if they change their recommendations regarding our Common Stock adversely, then the price and trading volume of our Common Stock could decline. The trading market for our Common Stock will be influenced by the research and reports that industry or securities analysts may publish about us, our business, our market, or our competitors. Accordingly, we must maintain confidence among current and future analysts, ratings agencies and other parties in our long-term financial viability and business prospects. Maintaining such confidence may be particularly complicated by certain factors including those that are largely outside of our control, such as limited operating history, market unfamiliarity, any delays in scaling manufacturing to meet demand and our eventual production and sales performance compared with the market expectations. If any of the analysts who may cover us change their recommendation regarding our Common Stock adversely, or provide more favorable relative recommendations about our competitors, the price of our Common Stock would likely decline. If any analyst who may cover us were to cease coverage of us, which occurred in November 2023 and may occur again in the future, or if any analyst fails to regularly publish reports on us, we could lose in the financial markets, which could cause our stock price or trading volume to decline. Future issuances of debt securities and equity securities may adversely affect us, including the market price of our Common Stock and may be dilutive to existing stockholders. In the future, we may incur debt or issue equity ranking senior to our Common Stock. Those securities will generally have priority upon liquidation. Such securities also may be governed by an indenture or other instrument containing covenants restricting its operating flexibility. Additionally, any convertible or exchangeable securities that we issue in the future may have rights, preferences and privileges more favorable than those of our Common Stock. Because our decision to issue debt or equity in the future will depend on market conditions and other factors beyond our control, we cannot predict or estimate the amount, timing, nature or success of our future capital raising efforts. As a result, future capital raising efforts may reduce the market price of our Common Stock and be dilutive to existing stockholders.

49 We have previously failed, and may again fail, to meet the listing standards of Nasdaq, resulting in our common stock being delisted, which could have a material adverse effect on its liquidity. Our Common Stock and the public warrants that were issued in connection with Artius’ initial public offering (the “Public Warrants”) are currently listed on Nasdaq. If we fail to continue to satisfy the continued listing requirements of Nasdaq, such as the corporate governance or public float requirements, or the minimum closing bid price requirement, Nasdaq will take steps to delist our common stock. In late 2023 and early 2024, the per share price of our common stock declined below the minimum bid price threshold required for continued listing. On January 4, 2024, we received a deficiency letter from the Listing Qualifications Department of the Nasdaq, notifying us that, for the last 30 consecutive business days, the closing bid price for our Class A common stock had closed below the minimum $1.00 per share required for continued listing on the Nasdaq pursuant to Nasdaq Listing Rule 5550(a)(2) (“Rule 5550(a)(2)”). In June 2024, our stock price resumed trading in excess of $1.00 per share for at least ten days, and we regained compliance with the minimum bid price requirement. There can be no assurance that we will remain in compliance with the minimum bid price requirement. There are many factors that may adversely affect our minimum bid price. Many of these factors are outside of our control. As a result, we may not be able to sustain compliance with Rule 5550(a)(2) in the long term. A failure to meet the requirements of the listing standards of Nasdaq may result in additional deficiency letters in the future. Any potential delisting of our common stock from the Nasdaq would likely result in decreased liquidity and increased volatility for our common stock and would adversely affect our ability to raise additional capital or to enter into strategic transactions, in addition to adversely impacting the perception of our financial condition and could cause reputational harm to investors and parties conducting business with us. Any potential delisting of our common stock from the Nasdaq would also make it more difficult for our stockholders to sell our common stock. Additionally, if our common stock is delisted from Nasdaq, the liquidity of our common stock would be adversely affected, the market price of our common stock could decrease, our ability to obtain sufficient additional capital to fund our operations and transactions in our common stock could lose federal preemption of state securities laws. Furthermore, there could also be a further reduction in our coverage by securities analysts and the news media and broker-dealers may be deterred from making a market in or otherwise seeking or generating interest in our common stock, which could cause the price of our common stock to decline further. Moreover, delisting may also negatively affect our clients’, customers’ and employees’ confidence in us and employee morale. Sales of a substantial number of shares of our common stock by our existing stockholders could cause the price of our common stock to decline. At any time, sales of a substantial number of shares of our common stock in the public market could occur, or there could be a perception in the market that the holders of a large number of shares of common stock intend to sell shares, and any such event could reduce the market price of our common stock. Substantially all of the shares of our common stock outstanding and shares issued upon the exercise of stock options outstanding under our equity incentive plans, subject to applicable securities law restrictions and excluding shares of restricted stock that will remain unvested, may be able to be sold in the public market. We are unable to predict the effect that sales may have on the prevailing market price of Common Stock and Public Warrants. To the extent our Warrants are exercised, additional shares of Common Stock will be issued, which will result in dilution to the holders of Common Stock and increase the number of shares eligible for resale in the public market. Sales, or the potential sales, of substantial numbers of shares in the public market by the selling securityholders could increase the volatility of the market price of Common Stock or adversely affect the market price of Common Stock.

50 There is no guarantee that the Warrants will be in the money at the time they become exercisable, and they may expire worthless. The exercise price for our Warrants is $11.50 per share of Common Stock. There is no guarantee that the Warrants will be in the money following the time they become exercisable and prior to their expiration, and as such, the Warrants may expire worthless. Our Warrants became exercisable on July 25, 2021. We may amend the terms of the Warrants in a manner that may be adverse to holders with the approval by the holders of at least 50% of the then-outstanding Public Warrants. As a result, the exercise price of your Warrants could be increased, the exercise period could be shortened and the number of shares of our Common Stock purchasable upon exercise of a Warrant could be decreased, all without your approval. Our Warrants are issued in registered form under the Warrant Agreement between the warrant agent and us. The Warrant Agreement provides that the terms of the Warrants may be amended without the consent of any holder to cure any ambiguity or correct any defective provision, but requires the approval by the holders of at least 50% of the then-outstanding Public Warrants to make any change that adversely affects the interests of the registered holders of Public Warrants. Accordingly, we may amend the terms of the Public Warrants in a manner adverse to a holder if holders of at least 50% of the then-outstanding Public Warrants approve of such amendment. Although our ability to amend the terms of the Public Warrants with the consent of at least 50% of the then-outstanding Public Warrants is unlimited, examples of such amendments could be amendments to, among other things, increase the exercise price of the Warrants, convert the Warrants into cash or stock (at a ratio different than initially provided), shorten the exercise period or decrease the number of shares of our Common Stock purchasable upon exercise of a Warrant. We may redeem unexpired Warrants prior to their exercise at a time that is disadvantageous to warrant holders, thereby making such Warrants worthless. We have the ability to redeem outstanding Warrants at any time after they become exercisable and prior to their expiration, at a price of $0.01 per Warrant, provided that the last reported sales price of our Common Stock equals or exceeds $18.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading-day period ending on the third trading day prior to the date on which we give proper notice of such redemption and provided certain other conditions are met. If and when the Warrants become redeemable by us, we may exercise our redemption right even if we are unable to register or qualify the underlying securities for sale under all applicable state securities laws. Redemption of the outstanding Warrants could force you (a) to exercise your Warrants and pay the exercise price therefor at a time when it may be disadvantageous for you to do so, (b) to sell your Warrants at the then-current market price when you might otherwise wish to hold your Warrants or (c) to accept the nominal redemption price which, at the time the outstanding Warrants are called for redemption, is likely to be substantially less than the market value of your Warrants. In addition, we may redeem your Warrants after they become exercisable for a number of shares of Common Stock determined based on the redemption date and the fair market value of our Common Stock. Any such redemption may have similar consequences to a cash redemption described above. In addition, such redemption may occur at a time when the Warrants are “out-of-the-money,” in which case, you would lose any potential embedded value from a subsequent increase in the value of our Common Stock had your Warrants remained outstanding.

51 We may issue additional shares of Common Stock or other equity securities without shareholder approval, which would dilute shareholders’ ownership interests and may depress the market price of the Common Stock. As of December 31, 2024 we have Warrants outstanding to purchase an aggregate of 35,476,627 shares of Common Stock. Pursuant to the Merger Agreement, we may issue up to 25,000,000 shares of our Common Stock as Earnout Shares. In addition, pursuant to the 2021 Equity Incentive Plan and the ESPP, we may issue an aggregate of up to 36,392,293 shares of Common Stock, which amount is subject to increase from time to time. We may also issue additional shares of Common Stock or other equity securities of equal or senior rank in the future in connection with, among other things, future acquisitions or repayment of outstanding indebtedness, without stockholder approval, in a number of circumstances. The issuance of additional shares or other equity securities of equal or senior rank would have the following effects: • existing stockholders’ proportionate ownership interest in us will decrease; • the amount of cash available per share, including for payment of dividends in the future, may decrease; • the relative voting strength of each previously outstanding share of Common Stock may be diminished; and • the market price of the Common Stock may decline. Item 1B. Unresolved Staff Comments None. Item 1C. Cybersecurity Risk management and strategy We have implemented and maintain information security processes designed to identify, assess, and manage material risks from cybersecurity threats to our critical computer networks, third-party hosted services, communications systems, hardware and software, and our critical data, including intellectual property and confidential information that is proprietary, strategic, or competitive in nature (“Information Systems and Data”). Our VP of Technology and Director of IT, together with our managed service provider (“MSP”), are responsible for helping to identify, assess and manage the Company’s cybersecurity threats and risks by monitoring and evaluating our threat environment using, among other things, manual processes, automated tools, internal audits, threat and vulnerability assessments, evaluating threats reported to us, evaluating our and our industry’s risk profile, and subscribing to reports and services that identify cybersecurity threats. Depending on the environment, we implement and maintain various technical, physical, and organizational measures, processes, standards, and policies designed to manage and mitigate material risks from cybersecurity threats to our information systems and data. These include, for example, an incident response plan and team, data encryption, risk assessments, network security and access controls, physical security, asset management, tracking, and disposal, systems monitoring, employee training including tabletop exercises and other simulated cybersecurity threats, and cybersecurity insurance. In addition, to oversee and identify any risks associated with our use of third-party service providers, we review Service Organization Controls (“SOC”) reports of such third- party service providers when onboarding the provider and annually thereafter. We also maintain proper essential information sharing and access controls, aiding in the secure exchange of information between us and our third- party service providers.

52 Assessment and management of material risks from cybersecurity threats are integrated into the Company’s overall risk management processes. For example, the Director of IT coordinates with our VP of Technology and representatives of the Company’s departments and teams to evaluate the Company’s risk profile and identify and mitigate cybersecurity threats. Our General Counsel evaluates material risks from cybersecurity threats and reports to both the Company’s executive management team and the Audit Committee of the Board of Directors. We also use third-party service providers to assist us from time to time to identify, assess, and manage material risks from cybersecurity threats, including for example cybersecurity consultants, data backup and recovery providers, cyber insurers, and legal counsel. For a description of the risks from cybersecurity threats that may materially affect the Company and how they may do so, see our risk factors under Part 1. Item 1A. Risk Factors in this Annual Report on Form 10-K. Governance Our Board of Directors (the “Board”) addresses the Company’s cybersecurity risk management as part of its general oversight function and has delegated to the Audit Committee primary responsibility for monitoring the Company’s cybersecurity risk management processes, including mitigation of cybersecurity threats. Our cybersecurity risk assessment and management processes are implemented and maintained by certain members of the Company’s management. In particular, the VP of Technology and Director of IT are responsible for hiring appropriate personnel and helping to integrate cybersecurity risk considerations into the Company’s overall risk management strategy, and communicating key priorities to relevant personnel, helping prepare for cybersecurity incidents, approving cybersecurity processes and technologies, and reviewing security assessments and other security-related reports. In addition, the General Counsel provides regular reports to the Audit Committee concerning the Company’s cybersecurity posture and significant threats and risks and the processes to address them. Our security incident response plan (“SIRP”) is designed to escalate certain cybersecurity incidents to members of the Company’s executive management team depending on the circumstances. Our VP of Technology, Director of IT, General Counsel, and MSP, along with relevant department heads, work with our incident response team to help the Company mitigate and remediate cybersecurity incidents of which they are notified. The SIRP provides for escalation of potentially material cybersecurity incidents to the Audit Committee. Item 2. Properties Our corporate headquarters, pilot-scale plant and research and development laboratories are located in West Sacramento, California, where we occupy approximately 41,443 square feet of office, plant and laboratory space. Our leases for this facility will expire on December 31, 2033. We believe that the facility that we currently lease is adequate for our needs for the immediate future and that, should it be necessary, we can lease additional space to accommodate any future growth. We also own a production facility in Sarnia, Ontario, Canada. This facility, Origin 1, is on approximately two acres of land and contains a construction trailer complete with approximately 5,402 square feet of office space. The land is owned by our wholly owned subsidiary, Origin Materials Canada Pioneer Limited and the offices are leased by our wholly owned subsidiary, Origin Materials Canada Polyesters Limited.

53 We purchased of approximately 183 acres in Geismar, Louisiana in third quarter 2022 in the amount of $8.5 million. The Company has concluded it will not construct an Origin 2 plant on the land owned in Geismar during the third quarter of 2024. As such, the Company obtained the approval from the Board to sell the property. The property is currently listed for sale, and it is the Company's intention to complete the sale of the land within the next 12 months. Item 3. Legal Proceedings Please see Note 16 “Commitments and Contingencies” in the notes to the consolidated financial statements in Item 8 of this Annual Report, which is incorporated herein by reference. Item 4. Mine Safety Disclosures Not applicable.

54 Part II Item 5. Market for Registrant’s Common Equity, Related Stockholder Matters and Issuer Purchases of Equity Securities Market Information Our Common Stock and Public Warrants are listed on NASDAQ under symbols “ORGN” and “ORGNW”, respectively. Holders As of close of business on March 7, 2025, there were 32 holders of record of our Common Stock and 1 holder of record for our Public Warrants. The actual number of holders of our Common Stock and Public Warrants is greater than the number of record holders, and includes holders who are beneficial owners, but whose shares or warrants are held in street name by brokers or other nominees. Dividend Policy We have never declared or paid any dividends and do not anticipate paying any dividends on our common stock in the foreseeable future. Recent Sales of Unregistered Equity Securities None. Issuer Purchases of Equity Securities None. Item 6. Reserved Item 7. Management’s Discussion and Analysis of Financial Condition and Results of Operations Overview Origin is a technology company with a mission to enable the world’s transition to sustainable materials. Our innovations include PET closures for an estimated global closures market opportunity of greater than $65 billion. Our PET closures enable fully-recyclable PET beverage containers and reduce waste through light-weighting, while providing enhanced performance such as greater oxygen and CO2 barrier properties that can increase shelf- life. Our furanics technologies include our furanics platform for transforming carbon into sustainable materials for a wide range of end products capable of addressing an estimated $1 trillion market opportunity, including food and beverage packaging, clothing, textiles, plastics, car parts, carpeting, tires, adhesives, soil amendments, and fuels. Our PET closures and technologies for producing them reflect our mission to enable the world's transition to sustainable materials, as well as our polymer expertise and platform development capability. We are going to market with what we believe is the first commercially viable PET closure. We anticipate that our PET closure

55 solutions can be transformative for packaging by designing for recycling circularity and improving the performance and sustainability of packaging. Our product candidate for markets include the PCO 1881 compliant PET closure and a tethered PET closure designed to comply with European cap tethering mandates and keep caps connected to bottles. Our first Origin CapFormer System, a PET closure manufacturing system, successfully completed its FAT, which involves a series of tests performed on the system to ensure that the system meets the requirements and functions as intended, in September 2024. Since September 2024, our CapFormer System has produced caps for commercial qualification and has been delivered to our operations and manufacturing center in Reed City, Michigan, where it commenced commercial production in February 2025. We anticipate bringing online additional CapFormer Systems as part of our scale-up strategy. In February 2025, we announced that three new CapFormer lines were nearing completion, with eight total lines expected by December 2025. In addition to our closures business, we have developed a number of technologies related to furanics, a class of chemicals with properties enabling the production of widespread and valuable materials, like plastics. These include our proprietary technology for transforming biomass, or plant-based carbon, into versatile intermediate chemicals. These intermediate chemicals include CMF and HTC, which we collectively refer to as Furanic Intermediates, as well as oils and extractives and other co-products. We believe that products made using our furanics technology at sufficient scale and maturity can compete directly with petroleum-derived products on both performance and price while being sustainable and lowering the carbon footprint. The following discussion and analysis should be read in conjunction with our consolidated financial statements and the related notes appearing elsewhere in this Annual Report. This discussion may contain forward-looking statements based upon current expectations that involve risks and uncertainties. Our actual results may differ materially from those anticipated in these forward-looking statements as a result of various factors, including those set forth in the sections titled “Cautionary Note Regarding Forward-Looking Statements” and “Risk Factors” as set forth elsewhere in this Annual Report. Unless the context otherwise requires, references in this section to “Legacy Origin”, “Origin”, “the Company”, “we”, “us” and “our” refer to the business and operations of Legacy Origin and its consolidated subsidiaries prior to the Merger and to Origin Materials, Inc. and its consolidated subsidiaries, following the closing of the Merger. Business Environment and Trends Our business and financial performance depend on worldwide economic conditions. We face global macroeconomic challenges, particularly in light of increases and volatility in interest rates, uncertainty in markets, inflationary trends, navigating complex and evolving regulatory frameworks, and the dynamics of the global trade environment. We continue to observe market uncertainty, civil unrest, global sanctions, bank failures, inflationary pressures, supply constraints and labor shortages in the past few quarters, and the potential changes in tariffs and trade barriers on major trading partners of the US including Canada and Mexico. In addition, several companies have announced products that may compete with our PET closures and biomass-derived chemicals and materials. These market dynamics, which we expect will continue into the foreseeable future, have and may continue to impact our business and financial results, including costs and revenues. Historically, demand for PET closures has been strong. However, no company has yet been able to successfully commercialize a PET closure at meaningful scale because of, among other factors, technical challenges inherent in making caps from PET cost-effectively in a way that customers have been willing to accept. We have approached the problem of PET closure production differently, including with novel applications of thermoforming and slit and fold technologies, as well as key proprietary design elements. Our solution does not

56 entail the use of custom polymers. As a result, we are going to market with what we believe is the first commercially viable PET closure. Our PET closures can enable our customers to fulfill sustainability and performance objectives including lighter packaging weights, increased recycled content, enhanced container recyclability, and improved product shelf life due to the superior gas barrier properties of PET compared with HDPE and polypropylene. Leading food and beverage companies increasingly embrace the vision of the circular economy, which seeks to minimize waste and keep valuable materials in circulation. Our PET closures offer clear value propositions for companies competing in this environment. We believe demand for our PET closures is likely to continue to exceed supply for the foreseeable future. Our commercial strategy will focus on increasing PET closure production capacity and expanding our PET closure technology into new product types and packaging markets including food and home goods. Product development continues to progress quickly as we engage with technical, strategic, and supply chain partners. Key Factors and Trends Affecting Our Operating Results We are in the early stages of generating revenue. We believe that our performance and future success depend on several factors that present significant opportunities for us but also pose risks and challenges, including those discussed below and under “Risk Factors” appearing elsewhere in this Annual Report. Basis of Presentation We currently conduct our business through one operating segment and our historical results are reported under accounting principles generally accepted in the United States of America (“U.S. GAAP”) and in U.S. Dollars. Upon commencement of commercial operations, we expect to expand our operations substantially, including in the United States and Canada, and as a result, we expect our future results to be sensitive to foreign currency transaction and translation risks and other financial risks that are not reflected in our historical financial statements. As a result, we expect that the financial results we report for periods after we begin commercial operations will not be comparable to the financial results included in this Annual Report. Components of Results of Operations We are in the relatively early stages of recognizing revenue and our historical results may not be indicative of our future results for reasons that may be difficult to anticipate. Accordingly, the drivers of our future financial results, as well as the components of such results, may not be comparable to our historical or projected results of operations. Revenues We evaluate financial performance and make resource allocation decisions based upon the results of our single operating and reportable segment. We generally procure, will produce, and sell product to be utilized in the manufacturing of finished products, for which we recognize revenue upon shipment. Our service contracts generally pay us at the commencement of the agreement and then at additional intervals as outlined in each contract. We recognize revenue as we satisfy the related performance obligations. Cost of Revenues

57 Cost of revenues for product sales consists primarily of cost associated with the purchase of finished goods. Cost of revenues for service agreements is based on the actual cost incurred, which mainly consists of the direct cost from vendors and overhead costs such as payroll and benefit related to our employees who provide the services to customers. Research and Development Expenses To date, our research and development expenses have consisted primarily of development of a new manufacturing process for PET closures that is different from the injection and compression molding methods traditionally used for HDPE and polypropylene closures. Different closure formats have different geometries and technical needs, including tolerances to pressure and temperature. We are advancing the practice of thermoforming to meet the performance demands of closures. For our furanics technologies, including our biomass conversion platform, and related intermediates, We have been developing commercialization pathways focused on high-value applications. Our furanics development work has a characteristically longer development cycle than our closures R&D. Our research and development expenses also include personnel-related costs like stock-based compensation and professional fees. General and Administrative Expenses General and administrative expenses consist primarily of personnel-related costs, including stock-based compensation and professional fees, including, the costs of accounting, audit, legal, regulatory and tax compliance. Other Income (Expenses) Our other income (expenses) consists of income from governmental grant programs, interest expenses for notes payable and other liabilities, interest and investment income (expenses) on marketable securities, realized gain or loss on marketable securities, investment fee, and gain or loss related to changes in the fair value of derivative assets and liabilities. We expect to incur incremental income (expenses) for the fair value adjustments of these assets and liabilities at the end of each reporting period. (Loss) Gain in Fair Value of Common Stock Warrants Liability The (loss) gain in fair value of common stock warrants liability consists of the change in fair value of the Warrants (the Public Warrants together with the Private Placement Warrants, the “Common Stock Warrants” or “Warrants”). We expect to incur incremental income (expenses) for the fair value adjustments for the outstanding common stock warrants liability at the end of each reporting period or through the exercise of the warrants. (Loss) Gain in Fair Value of Earnout Liability The (loss) gain in fair value of earnout liability consists of the change in fair value of the future contingent equity shares related to the Merger. We recognize incremental income (expense) for the fair value adjustments of the outstanding liability at the end of each reporting period. Income Tax (Expenses) Benefits Our income tax (provision) benefit consist of an estimate for U.S. federal, state, and foreign income taxes based on enacted rates, as adjusted for allowable credits, deductions, uncertain tax positions, changes in deferred tax assets and liabilities, and changes in the tax law. We maintain a valuation allowance against the full value of our

58 U.S. federal and state, net deferred tax assets and certain foreign net deferred tax assets because we believe the recoverability of the tax assets is not more likely than not. We have released the valuation allowance previously recorded against some of the foreign net deferred tax assets as we believe it is more likely than not they will be recovered.

59 Results of Operations Comparison of the years ended December 31, 2024 and 2023 The following table summarizes our results of operations with respect to the items set forth in such table for the years ended December 31, 2024 and 2023 together with the change in such items in dollars and as a percentage.

60 Year Ended December 31, (in thousands) 2024 2023 Variance $ Variance % Revenues: Products $ 31,279 $ 23,896 $ 7,383 31 % Services 3 4,909 (4,906) (100) % Total revenues 31,282 28,805 2,477 9 % Cost of revenues (exclusive of depreciation and amortization shown separately below) 30,864 23,591 7,273 31 % Operating expenses: Research and development 18,554 21,351 (2,797) (13) % General and administrative 40,766 35,382 5,384 15 % Depreciation and amortization 10,715 3,363 7,352 219 % Impairment of assets 15,246 — 15,246 100 % Total operating expenses 85,281 60,096 25,185 42 % Loss from operations (84,863) (54,882) (29,981) 55 % Other income (expenses): Investment income 6,783 6,303 480 8 % Interest expenses (371) (131) (240) 183 % Gain in fair value of derivatives 290 69 221 320 % (Loss) gain in fair value of common stock warrants liability (3,225) 29,531 (32,756) (111) % (Loss) gain in fair value of earnout liability (703) 40,983 (41,686) (102) % Other (expenses) income, net (939) 838 (1,777) (212) % Total other income, net 1,835 77,593 (75,758) (98) % (Loss) income before income tax (provision) benefit (83,028) 22,711 (105,739) (466) % Income tax (provision) benefit (669) 1,087 (1,756) (162) % Net (loss) income $ (83,697) $ 23,798 $ (107,495) (452) %

61 Revenues Revenues increased $2.5 million, or 9%, during the year ended December 31, 2024 compared to 2023. The increase in product revenue is primarily generated by our supply chain activation program. For additional information regarding our supply chain activation program, see Note 4 - Revenues to the consolidated financial statements in Item 8 of this Annual Report. Cost of Revenues Cost of revenues increased $7.3 million, or 31%, during the year ended December 31, 2024 compared to 2023. The increase is primarily attributable to the purchases associated with our supply chain activation program. Research and Development Expenses Research and development expenses decreased $2.8 million, or (13)%, during the year ended December 31, 2024 compared to 2023. The changes are mainly attributable to $1.1 million decrease in insurance and facilities expenses as Origin 1 is currently operating “on demand” with reduced staffing, $0.9 million payroll reduction related to the reduction in force in September 2024, $0.1 million decrease in stock-based compensation, $0.2 million decrease in professional fees, and $0.2 million decrease in software and licenses fees. General and Administrative Expenses General and administrative expenses increased $5.4 million, or 15%, during the year ended December 31, 2024 compared to 2023. The increase is primarily driven by the operation costs related to Origin 1 including $2.3 million increase in equipment, maintenance and repairs, $2.1 million increase in insurance and facilities, $2.0 million increase in payroll expenses and $1.1 million increase in stock-based compensation, partially offset by a $3.0 million decrease in professional fees. A significant portion of costs incurred during 2023 were capitalized as part of the development of Origin 1 and the costs to operate and maintain the plant are included in general and administrative expenses in 2024. Depreciation and Amortization Expenses Depreciation and amortization expenses increased $7.4 million, or 219%, during the year ended December 31, 2024 compared to 2023. The increase is mainly driven by the completion of Origin 1 during the fourth quarter of 2023. Impairment of Assets Impairment of assets increased $15.2 million, or 100%, during the year ended December 31, 2024 compared to 2023. The increase is comprised of the impairment loss of $12.3 million related to the capitalized costs specific

62 to the Louisiana site for Origin 2 that were deemed not recoverable and a $2.9 million write-down of other current assets to fair market value of purchased product. Changes in Fair Value of Derivatives, Common Stock Warrants Liability, and Earnout Liability We recognized an aggregate loss related to the changes in fair values of derivative, common stock warrant liability, and earnout liability of $3.6 million during the year ended December 31, 2024 compared to an aggregate gain of $70.6 million in 2023. The aggregate loss related to the change in fair values decreased $74.2 million. The decrease related to the change in fair value of earnout liability of $41.7 million is the result of the revaluation of the earnout liability with the fair value of such liability increasing during the year ended December 31, 2024 as compared to decreasing in 2023. The $32.8 million decrease related to the change in fair value of common stock warrant liability is the result of an increase in the fair value of the common stock warrants during the year ended December 31, 2024 as compared to a decrease in 2023. The movement in these instruments’ fair values are driven by the value of our stock price. This decrease was offset by the increase of $0.3 million in the gain from change in fair value of derivative associated with our foreign currency exchange purchases or sales. Other (Expenses) Income, Net Other (expenses) income, net increased $1.8 million, or (212)%, from other expenses of $0.9 million during the year ended December 31, 2024 compared to other income of $0.8 million in 2023. The increase in other expenses is mainly driven by the $0.9 million realized loss on marketable securities during the year ended December 31, 2024 as compared to the realized gain of $0.9 million in 2023. Income Tax (Provision) Benefit Income tax provision increased $1.8 million, or (162)%, during the year ended December 31, 2024 compared to 2023. The increase is driven by the tax on income generated by the Canadian entities as a result of the establishment of intercompany transfer pricing. Non-GAAP Measures To provide investors with additional information in connection with our results as determined in accordance with U.S. GAAP, we disclose Adjusted Earnings before Interest, Taxes, Depreciation, and Amortization (“Adjusted EBITDA”) as a non-GAAP measure. Adjusted EBITDA is a key metric used by management and our board to assess our financial performance. Adjusted EBITDA is also frequently used by analysts, investors, and other interested parties to evaluate companies in our industry, when considered alongside other U.S. GAAP measures. We use Adjusted EBITDA to supplement U.S. GAAP measures of performance to evaluate the effectiveness of our business strategies, make budgeting decisions and compare our performance against that of other companies using similar measures. This measure is not a financial measure calculated in accordance with U.S. GAAP, and it should not be considered as a substitute for net income, operating income, or any other measure calculated in accordance with U.S. GAAP, and may not be comparable to similarly titled measures reported by other companies. Adjusted EBITDA We believe that the presentation of Adjusted EBITDA is appropriate to provide additional information to investors about our operating profitability adjusted for certain non-cash items, non-routine items that we do not expect to continue at the same level in the future, as well as other items that are not core to our operations. Further, we believe Adjusted EBITDA provides a meaningful measure of operating profitability because we use it for evaluating our business performance, making budgeting decisions, and comparing our performance against that of other peer companies using similar measures.

63 We define Adjusted EBITDA as net income or loss adjusted for certain non-cash and non-recurring items, including (i) stock-based compensation, (ii) depreciation and amortization, (iii) impairment of assets, (iv) investment income, (v) interest expenses, (vi) change in fair value of derivatives, (vii) change in fair value of common stock warrants liability, (viii) change in fair value of earnout liability, (ix) other expenses (income), net, (x) income tax expenses (benefits) and (xi) cash severance.

Liquidity and Capital Resources Sources of Liquidity Since inception, we have financed our operations principally from the sales and issuances of common stock, and governmental grant programs. We had $102.9 million in cash, cash equivalents, and marketable securities as of December 31, 2024, and we believe that this balance will be able to fund its planned operations for at least the twelve months following the filing of this Annual Report on Form 10-K. We may need substantial additional

64 financing to increase the manufacturing lines for the growth of our closures business. Our ability to obtain financing may depend on our ability to first enter into customer agreements sufficient to demonstrate sufficient demand to justify the additional manufacturing lines. Our cash equivalents are invested primarily in U.S. Treasury money market funds and our marketable securities are primarily U.S. government and agency securities, corporate bonds, asset-backed securities, foreign government and agency securities, and municipal bonds. We began generating revenue from our business operations in 2023. Our ability to successfully develop the products, commence commercial operations and expand the business will depend on many factors, including our ability to meet the working capital needs, the availability of equity or debt financing and, over time, our ability to generate cash flows from operations. We will require a significant amount of cash for capital expenditures as we invest in manufacturing lines for our PET closures business. In addition to our cash on hand, we anticipate that we will need substantial additional project financing, including from strategic partners, and government incentives to meet our financial projections, execute our growth strategy and expand our manufacturing capability. We may also enter into additional strategic partnerships to finance the development of closures manufacturing lines. Our ability to obtain financing for the construction of future Origin manufacturing facilities may depend in part on our ability to first enter into customer agreements sufficient to demonstrate adequate demand to justify the capital expenditure. We may also raise additional capital through equity offerings or debt financings, as well as through collaborations, strategic alliances or marketing, distribution or licensing arrangements with third parties. Our future capital requirements will depend on many factors, including actual costs of our manufacturing lines or plants, changes in the costs in our supply chain, expanded operating activities and our ability to secure customers. If our financial projections are inaccurate, we may need to seek additional equity or debt financing from outside sources, which may not be available on acceptable terms, if at all. If we are unable to raise additional capital when required, our business, financial condition and results of operations would be harmed. We expect to continue to incur operating losses in the near term as our operating and capital expenses are needed to support the growth of the business. We expect that our general and administrative expenses will continue to increase as we develop our PET closures business, increase our spending on strategic partnerships, increase our sales and marketing activities, produce materials and operate as a public company. Indebtedness As of December 31, 2024 and 2023, we had $14.4 million and $7.3 million of indebtedness under a Canadian government program, respectively, of which $8.1 million and zero was received during the years ended December 31, 2024 and 2023, respectively. Additionally, as of December 31, 2024, we had liability balances consisting of $1.7 million notes payable, long-term, $3.8 million notes payable, short-term, $0.1 million unpaid accrued interest recorded in other liabilities, current, and a $2.5 million customer prepayment recorded in other liabilities, current. As of December 31, 2023, we had liability balances consisting of $3.5 million notes payable, long-term, $1.7 million notes payable, short-term, $0.8 million unpaid accrued interest recorded in other liabilities, current, $5.7 million other liabilities, long-term with unpaid accrued interest and a $2.5 million customer prepayment recorded in other liabilities, long-term.

65 In November 2016, Legacy Origin received a $5.0 million prepayment from a legacy stockholder for product from Origin 1 pursuant to an “Offtake Agreement,” a type of agreement that generally provided for binding take- or-pay commitments to purchase certain annual volumes of product from our planned manufacturing facilities at specified prices, subject to satisfaction of certain conditions precedent. The prepayment was to be credited against the purchase of products over the term of the agreement. The prepayment was secured by a promissory note to be repaid in cash in the event that the prepayment could not be credited against the purchase of product, for example, if Origin 1 were never constructed. The promissory note was collateralized substantially by Origin 1 and other assets of Origin Materials Canada Pioneer Limited. In May 2019, Legacy Origin and the legacy stockholder amended the Offtake Agreement and promissory note. The amendment added accrued interest of $0.2 million to the principal balance of the prepayment and provided for the prepayment amount to be repaid in three annual installments rather than being applied against the purchase of product from Origin 1. On August 1, 2022, the Company and the legacy stockholder amended the promissory note to provide for repayment in three installments consisting of both principal and interest (at 3.5% per annum) of $2.7 million on September 1, 2024, $1.9 million on September 1, 2025, and $1.8 million on September 1, 2026 and to allow the legacy stockholder to offset amounts owed for the purchase of product from Legacy Origin’s Origin 1 facility against amounts due under the promissory note. At December 31, 2024 the outstanding note principal balance was $3.5 million of which $1.7 million was included in notes payable, long-term and $1.8 million was included in notes payable, short-term and the outstanding accrued interest of less than $0.1 million was included in other liabilities, current. At December 31, 2023, the outstanding note principal balance was $5.2 million of which $3.5 million was included in notes payable, long-term and $1.7 million was included in notes payable, short-term and the outstanding accrued interest of $0.8 million was included in other liabilities, current.

66 In November 2016, Legacy Origin received a $5.0 million prepayment from a legacy stockholder for product from Origin 1 pursuant to an Offtake Agreement. The prepayment was to be credited against the purchase of products from Origin 1 over the term of the Offtake Agreement, specifically by applying a credit to product purchases each month over the first five years of operation of Origin 1 up to 150% of the prepayment amount— i.e., $7.5 million. The application of the credit to purchases would continue until the foregoing amount was fully repaid. The prepayment is secured by a note to be repaid in cash in the event the prepayment cannot be credited against the purchase of product, for example, if Origin 1 were never constructed. The note is collateralized substantially by Origin 1 and other assets of Origin Materials Canada Pioneer Limited. If repaid in cash, the note bears an annual interest rate of the three-month Secured Overnight Financing Rate (“SOFR”) plus 0.25% (4.94% at December 31, 2024) and matures five years from the commercial operation date of Origin 1. In February 2024, the Company and the legacy stockholder amended the agreement to provide for repayment with interest accrual in three installments consisting of approximately $2.2 million on March 1, 2024, $1.6 million on September 1, 2024, and $2.1 million on March 1, 2025 instead of applying a credit to product purchases under the Offtake Agreement. As a result, the principal amounts outstanding under the agreement were reclassified from other liabilities, long-term to notes payable, short-term and the accrued interest was reclassified from other liabilities, long-term to other liabilities, current during the year ended December 31, 2024. The outstanding principal of $2.0 million at December 31, 2024 was recorded in notes payable, short-term and less than $0.1 million accrued interest outstanding was recorded in other liabilities, current. At December 31, 2023, the total amount outstanding was $5.1 million and accrued interest outstanding was $0.6 million recorded in other liabilities, long-term. Prepayments In September 2019, Legacy Origin entered into a $5.0 million prepayment agreement with a counterparty for the purchase of products from Origin 2. The prepayment is to be made in two equal installments: the first $2.5 million was in October 2019 and the remaining $2.5 million is due within 30 days of the customer confirming that a sample from Origin 1 meets the customer’s specifications. We and the customer agreed to work in good faith to execute an Offtake Agreement, the agreed terms of which are set forth in the prepayment agreement, whereby 100% of the prepayment will be applied against future purchases. The prepayment agreement provides the customer a capacity reservation of up to a specified annual volume of product from Origin 1 for a term of ten years, pursuant to the terms of an Offtake Agreement. At December 31, 2024 and 2023, the total amount outstanding on this agreement was $2.5 million. On February 5, 2024, the parties entered into a memorandum of understanding (“MOU”) by which they agreed that the counterparty would be released from its obligation to pay the remaining $2.5 million of the prepayment and that Legacy Origin would refund the first $2.5 million within a certain period after reporting in its Quarterly Report on Form 10-Q that its cash on hand has crossed a specified threshold. In November 2024, the parties entered into a second MOU providing for the return of the counterparty's first prepayment, without regard to cash on hand, termination of the prepayment agreement, and a waiver of each party's rights, claims, and demands associated with that agreement. Under the second MOU, the Company anticipates returning the prepayment on or about March 10, 2025 and provides for the payment of interest at an annual rate of 14.6% if such prepayment is returned later. As such, the $2.5 million was reclassified from other liabilities, long-term to other liabilities, current on the consolidated balance sheets as of December 31, 2024.

67 Cash Flows for the Year Ended December 31, 2024 Compared to the Year Ended December 31, 2023 The following table shows a summary of cash flows for the years ended December 31, 2024 and 2023: Year ended December 31, (in thousands) 2024 2023 Net cash used in operating activities $ (50,830) $ (60,355) Net cash provided by investing activities 28,559 26,232 Net cash provided by financing activities 3,556 146 Effects of foreign exchange rate changes on the balance of cash and cash equivalents, and restricted cash (480) 1,131 Net decrease in cash, cash equivalents and restricted cash $ (19,195) $ (32,846) Cash Used in Operating Activities Net cash used in operating activities for the year ended December 31, 2024 was $50.8 million. Non-cash expenses recognized that were added back to the net loss of $83.7 million include $15.2 million impairment loss, $10.7 million depreciation and amortization, $10.1 million stock-based compensation and $3.2 million change in fair value of common stock warrants liability. These adjustments were partially offset by the $3.4 million increase in accounts receivable and other receivables, $4.8 million increase in other long-term assets, and $3.6 million decrease in accrued expenses. Net cash used in operating activities for the year ended December 31, 2023 was $60.4 million. Non-cash income recognized for the $41.0 million change in the fair value of earnout liability and $29.5 million for the change in fair value of common stock warrants liability were deducted from net income of $23.8 million, in addition to the $15.2 million increase in accounts and other receivables and the $12.8 million increase in other long-term assets. These adjustments were partially offset by additions for non-cash charges of $9.4 million for stock-based compensation and $3.4 million for depreciation and amortization, as well as $5.9 million for the increase in accrued expenses. Cash Provided by Investing Activities Net cash provided by investing activities was $28.6 million for the year ended December 31, 2024, compared to net cash provided by investing activities of $26.2 million over the same period in 2023. The change was primarily related to the decrease in license prepayment of $7.9 million and decrease in purchases of property, plant and equipment of $93.2 million due to the completion of Origin 1 during the fourth quarter of 2023. These adjustments were offset by the increase in net purchases of marketable securities of $44.7 million and the decrease in maturities of marketable securities of $54.1 million.

68 Cash Provided by Financing Activities Net cash provided by financing activities was $3.6 million for the year ended December 31, 2024, compared to net cash provided by financing activities of $0.1 million over the same period in 2023. The change was primarily related to the proceeds from Canadian Government Research and Development Program of $8.1 million which was partially offset by the payment of $4.8 million on the notes payable. Material Cash Requirements from Known Contractual and Other Obligations Our material cash requirements from known contractual and other obligations as of December 31, 2024 consisted of: • Operating lease liabilities that are included on our consolidated balance sheets consists of future non- cancelable minimum rental payments under operating leases for our office space, research and development space, and leases of various office equipment, and warehouse space. Operating lease liabilities of $0.3 million are short term and the remaining $3.9 million is long-term. For additional information regarding our operating lease liabilities, see Note 15 “Leases” to the consolidated financial statements in Item 8 of this Annual Report. • In the near-term, we anticipate making payments related to the repayment agreement associated with the notes payable. The remaining repayment in the amount of $1.9 million is due on September 1, 2025, and $1.8 million is due on September 1, 2026 (inclusive of accrued but unpaid interest). However, the prepayment could be used to credit against the purchase of products over the term of the Offtake Agreement. For additional information regarding this repayment, see Note 7 “Notes Payable” to the consolidated financial statements in Item 8 of this Annual Report. • We amended the agreement with another customer in February 2024 to provide for repayment in three installments. We paid the first two installments, and the remaining repayment amount, including both principal and accrued interest of $2.1 million, is due on March 1, 2025. Unlike the repayment agreement above, this prepayment cannot be repaid by means of a credit against the purchase of products. For additional information regarding this repayment, see Note 7 “Notes Payable” to the consolidated financial statements in Item 8 of this Annual Report. • We have a prepayment agreement with a counterparty for $2.5 million due within 30 days of the customer confirming that a sample from Origin 1 meets the customer’s specifications. On February 5, 2024, the parties to the prepayment agreement entered into a memorandum of understanding (“MOU”) by which they agreed that the counterparty would be released from its obligation to pay the remaining $2.5 million of the prepayment and that Legacy Origin would refund the first $2.5 million within a certain period after reporting in its Quarterly Report on Form 10-Q that its cash on hand has crossed a specified threshold. In November 2024, we entered into a second MOU providing for the return of the counterparty's first prepayment, without regard to cash on hand, termination of the prepayment agreement, and a waiver of each party's rights, claims, and demands associated with that agreement. Under the second MOU, we anticipate returning the prepayment on or about March 10, 2025 and provides for the payment of interest at an annual rate of 14.6% if such prepayment is returned later. As such, the $2.5 million was reclassified from other liabilities, long-term to other liabilities, current on the consolidated balance sheets as of December 31, 2024. For additional information regarding this

69 repayment, see Note 8 “Other Liabilities” to the consolidated financial statements in Item 8 of this Annual Report. • The operating cost of Origin 1 and our ongoing operating loss are expected to be funded through a combination of Company cash and marketable securities in addition to substantial project financing and government incentives. Critical Accounting Policies and Estimates Our financial statements have been prepared in accordance with U.S. GAAP. In the preparation of these consolidated financial statements, we are required to use judgment in making estimates and assumptions that affect the reported amounts of assets and liabilities and the disclosure of contingent assets and liabilities as of the date of the financial statements, as well as the reported expenses incurred during the reporting periods. On an ongoing basis, we evaluate our estimates and assumptions. Our actual results may differ from these estimates under different assumptions or conditions. We consider an accounting judgment, estimate or assumption to be critical when (1) the estimate or assumption is complex in nature or requires a high degree of judgment and (2) the use of different judgments, estimates and assumptions could have a material impact on the consolidated financial statements. Our significant accounting policies are described in Note 2 “Summary of Significant Accounting Policies” to our consolidated financial statements included in Item 8 of this Annual Report. We have the critical accounting policies and estimates which are described below. Revenue Recognition We recognize revenue in accordance with Accounting Standards Codification (“ASC”) 606, Revenue from Contracts with Customers (“ASC 606”). The core principle of ASC 606 requires that an entity recognize revenue to depict the transfer of promised goods or service to customers in an amount that reflects the consideration to which we expect to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under our product revenue and service agreements, we perform the following steps: 1. Identifying the contract with a customer; 2. Identifying the performance obligations in the contract; 3. Determining the transaction price; 4. Allocating the transaction price to the performance obligations; and 5. Recognizing revenue when, or as, the performance obligations are satisfied. We account for a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Non-cancellable purchase orders received from customers to deliver a specific quantity of product, when combined with our order confirmation, in exchange for future consideration, create enforceable rights and obligations on both parties and constitute a contract with a customer. Our service agreements are customized, specified, and often include various stages at which transaction prices are agreed to. These service agreements often include multiple performance obligations within each stage. We identify each performance obligation at contract inception and allocate the consideration to each distinct performance obligation based on the stand-alone selling price of each performance obligation. Our services are

70 tailored to each individual customer and the stand-alone selling prices are not directly observable. As our service agreements include customers that are not in similar geographic markets and for different services, therefore we use the expected cost plus margin approach to estimate the stand-alone selling price for each of our performance obligations. We recognize revenue from the service agreements over the period during which the services are performed and recognize the associated costs as they are incurred. In general, we recognize revenue when, or as, our performance obligations under the terms of a contract with our customer are satisfied. We consider this to be is a critical accounting policy and estimate. Impairment of Long -Lived Assets Long-lived assets are assessed for potential impairment in accordance with U.S. GAAP. We review our long-lived assets, including property, plant and equipment, operating lease right-of-use (“ROU”) assets, intangible assets and other long-term assets, for impairment whenever there is evidence that events and circumstances related to our financial performance and economic environment indicate the carrying amount of the assets may not be recoverable. When impairment indicators are identified, we test for impairment using undiscounted projected cash flows or the estimated fair value based on the best information available. The estimate of undiscounted cash flows is based upon, among other things, certain assumptions about future operating performance, growth rates and other factors. Estimates of undiscounted cash flows may differ from actual cash flows due to, among other things, technological changes, economic condition, changes to the business model or changes in operating performance. If the total of the expected undiscounted future net cash flows or the estimated fair value for the asset group is less than the carrying amount of the asset group, a loss is recognized for the difference between the estimated fair value and carrying amount of the asset group. Significant management judgment is required in forecasting future operating results used in the preparation of the projected cash flows and fair value estimates and our estimates may differ from the actual results. Should different conditions prevail, material write downs of our long-lived assets could occur. While we believe that the assumptions and estimates utilized were appropriate based on the information available to management, different assumptions, judgments and estimates could materially affect our impairment assessments for our long-lived assets. Therefore, we consider this to be a critical accounting estimate. Recent Accounting Pronouncements See Note 3 “Recent Accounting Pronouncements” to the consolidated financial statements in Item 8 of this Annual Report for more information about recent accounting pronouncements, the timing of their adoption, and our assessment, to the extent we have made one, of their potential impact on our financial condition and results of operations and cash flows. Item 7A. Quantitative and Qualitative Disclosures About Market Risk As a “smaller reporting company” as defined by Item 10 of Regulation S-K, we are not required to provide the information required by Item 305 of Regulation S-K.

72 REPORT OF INDEPENDENT REGISTERED PUBLIC ACCOUNTING FIRM To the stockholders and the Board of Directors of Origin Materials, Inc. Opinion on the Financial Statements We have audited the accompanying Consolidated Balance Sheets of Origin Materials, Inc. and subsidiaries (the “Company”) as of December 31, 2024 and 2023, the related Consolidated Statements of Operations and Comprehensive (Loss) Income, Stockholders’ Equity and Cash Flows, for each of the two years in the period ended December 31, 2024, 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, 2024 and 2023, and the results of its operations and its cash flows for each of the two years in the period ended December 31, 2024, in conformity with accounting principles generally accepted in the United States of America. 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 Public Company Accounting Oversight Board (United States) (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. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. 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. Critical Audit Matter The critical audit matter communicated below is a matter arising from the current-period audit of the financial statements that was communicated or required to be communicated to the audit committee and that (1) relates to accounts or disclosures that are material to the financial statements and (2) involved our especially challenging, subjective, or complex judgments. The communication of critical audit matters does not alter in any way our opinion on the financial statements, taken as a whole, and we are not, by communicating the critical audit matter below, providing a separate opinion on the critical audit matter or on the accounts or disclosures to which it relates.

73 Property, Plant and Equipment, Net — Impairment of Long-Lived Assets — Refer to Notes 2 and 6 to the financial statements Critical Audit Matter Description The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If indicators of impairment exist, management identifies the asset group which includes the potentially impaired long-lived asset at the lowest level at which there are separate, identifiable cash flows. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset group and its eventual disposition or its estimated fair value based on the best information available. If the total of the expected undiscounted future net cash flows or the estimated fair value for the asset group is less than the carrying amount of the asset group, a loss is recognized for the difference between the estimated fair value and carrying amount of the asset group. During the year ended December 31, 2024, the Company determined that indicators of impairment existed for its Origin 1 and Origin 2 asset groups. The significant assumptions used by the Company to determine the undiscounted cash flows expecting to result from the use of the Origin 1 asset group included additional capital expenditure requirements, projected revenue, and general operating costs. The Company’s significant estimates to determine the fair value of the Origin 2 asset group included the estimated fair value of land using appraisal information and the estimated fair value of costs capitalized to construction in progress. We identified the Company’s review of the long-lived assets of the Origin 1 and Origin 2 asset groups for impairment as a critical audit matter because forecasting future operating results used in the preparation of the projected undiscounted cash flows and making fair value estimates in the determination of recoverability of the long-lived assets required significant management judgment. This required a high degree of auditor judgment and an increased extent of effort when performing audit procedures to evaluate the reasonableness of estimates and assumptions related to the additional capital expenditure requirements, projected revenue, and general operating costs for the Origin 1 asset group and the fair value estimates of land and costs capitalized to construction in progress for the Origin 2 asset group. How the Critical Audit Matter Was Addressed in the Audit Our audit procedures related to management’s estimates and assumptions used in determining additional capital expenditure requirements, projected revenue, and general operating costs for the Origin 1 asset group and fair value estimates of land and costs capitalized to construction in progress for the Origin 2 asset group included the following, among others: • We evaluated the reasonableness of management’s estimates and assumptions used in the determination of the undiscounted cash flows expecting to result from the use of the Origin 1 asset group, including additional capital expenditure requirements, projected revenue, and general operating costs by: ◦ Performing corroborative inquiries with individuals in operations, including individuals responsible for developing the data used by management in making the significant estimates and assumptions.

74 ◦ Evaluating the reasonableness of the additional capital expenditure requirements, projected revenue, and general operating costs by comparing the assumptions used to external market sources, information regarding the Company’s planned future strategies, and results from other areas of the audit. ◦ Developing a range of estimates for the undiscounted cash flows and comparing them to those determined by the Company. • We evaluated the reasonableness of management’s estimates and assumptions used in the fair value estimates of land and costs capitalized to construction in progress for the Origin 2 asset group by: ◦ Performing corroborative inquiries with individuals in operations, including individuals responsible for developing the data used by management in making the significant estimates and assumptions. ◦ Comparing the historical cost data in the fair value estimates to the Company’s underlying accounting records. ◦ Evaluating the appraisal information used by management to estimate the fair value of land. ◦ Evaluating the reasonableness of the estimates of the percentage of internal and external capitalized costs determined to be recoverable as part of determining the fair value of costs capitalized to construction in progress for Origin 2 by comparing the assumptions used to historical data and information regarding the Company's planned future strategy. ◦ Developing an estimate of the percentage of internal and external costs determined to be recoverable and comparing them to those determined by the Company. /s/ DELOITTE & TOUCHE LLP Sacramento, California March 13, 2025 We have served as the Company's auditor since 2023.

81 ORIGIN MATERIALS, INC. NOTES TO CONSOLIDATED FINANCIAL STATEMENTS 1. Organization and Business Unless the context otherwise requires, references in these notes to “Origin”, “the Company”, “we”, “us” and “our” and any related terms are intended to mean Origin Materials, Inc. and its consolidated subsidiaries. In June 2021, Artius Acquisition Inc. (“Artius”), a special purpose acquisition company, completed a merger with Micromidas, Inc., a Delaware corporation (now known as Origin Materials Operating, Inc. (“Legacy Origin”)). Pursuant to the terms of the Merger Agreement (the agreement formalizing the business combination between Artius and Legacy Origin), Legacy Origin became a wholly-owned subsidiary of Artius (the “Merger”) and Artius changed its name to Origin Materials, Inc. (together with its subsidiaries, the “Company”). The Company is a technology company with a mission to enable the world's transition to sustainable materials. Origin has developed multiple sustainable and performance-enhanced solutions for improving recycling and circularity, including our polyethylene terephthalate (“PET”) closures, as well as low-carbon material solutions for a wide variety of products and applications. The Company’s furanics technology can transform sustainable feedstocks, such as sustainably harvested wood, agricultural waste, wood waste and corrugated cardboard, into materials and products that are currently made from fossil feedstocks, such as petroleum and natural gas. Origin announced its PET closures business in August 2023 after several years of application development related to its furanics technologies. Origin's announced products include the PCO 1881 compliant PET closure and a tethered PET closure designed to comply with European cap tethering mandates and keep caps connected to bottles. Origin has announced several manufacturing partnerships with machine subsystem suppliers, including slit and fold specialists and a provider of visual inspection systems. Mass production partnerships are in place in Europe and North America. Origin's first PET closure manufacturing system successfully completed its Factory Acceptance Test, which involves a series of tests performed on the system to ensure that the system meets the requirements and functions as intended, in September 2024. The Company achieved the mechanical completion of its first furanics manufacturing plant in Ontario, Canada (“Origin 1”). The plant is currently operating on demand with reduced staffing, while preserving Origin's ability to generate product at small volumes sufficient to explore scale-up with strategic partners.

82 2. Summary of Significant Accounting Policies Basis of Presentation The Company’s consolidated financial statements have been prepared in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) as determined by the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) and pursuant to the regulations of the U.S. Securities and Exchange Commission (“SEC”). Use of Estimates The preparation of the consolidated financial statements in accordance with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of commitments and contingencies at the date of the financial statements as well as reported amounts of revenues, costs and expenses during the reporting periods. Estimates made by the Company include, but are not limited to, allowance for credit losses, valuation of the earnout liability, carrying amount and useful lives of property, plant and equipment and intangible assets, impairment assessments, stock-based compensation expense and probabilities of achievement of performance conditions on performance-based stock (“PSU”) awards, among others. The Company bases these estimates on historical experience and on various other assumptions that it believes are reasonable under the circumstances, the results of which form the basis for making judgments about the carrying amounts of assets and liabilities that are not readily apparent from other sources. Actual results could differ materially from those estimates. Principles of Consolidation The consolidated financial statements have been prepared in accordance with U.S. GAAP and applicable rules and regulations of the SEC and include the accounts of the Company and its wholly-owned subsidiaries. All intercompany accounts and transactions have been eliminated in consolidation. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk are primarily cash, cash equivalents, marketable securities and accounts receivable. The Company maintains its cash and cash equivalents at financial institutions insured by the Federal Deposit Insurance Corporation (“FDIC”) up to $250,000 per institution. As the account balances at each institution periodically exceed the FDIC insurance coverage, there is a concentration of credit risk related to amounts in excess of such coverage. While the Company has not experienced losses of these deposits to date, future disruptions of financial institutions where we bank or have credit arrangements, or disruptions of the financial services industry in general, could adversely affect our ability to access our cash and cash equivalents. If we are unable to access our cash and cash equivalents as needed, our financial position and ability to operate our business could be adversely affected. The Company's marketable securities consists of investment-grade securities diversified among security types that are held at financial institutions that management believes to be of high credit quality. The Company records the provision for credit losses within general and administrative expenses on the consolidated statements of operations and comprehensive (loss) income, up to the amount of total outstanding accounts receivable to date. Our top two customers from product sales, in the aggregate, accounted for approximately 93% and 67% as of December 31, 2024 and 2023, respectively, of total accounts receivable

83 outstanding balances and accounted for approximately 96% and 77% of total revenues for the years ended December 31, 2024 and 2023, respectively. Cash and Cash Equivalents The Company considers all highly liquid investments with an initial maturity of three months or less at the date of purchase to be cash equivalents. Cash equivalents are comprised of money market funds. Marketable Securities The Company’s investment policy requires the Company to purchase investments that are consistent with the classification of available-for-sale securities. The Company does not buy and hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity, and return. The Company considers all of its marketable debt securities as available for use in current operations, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the consolidated balance sheets. Securities are classified as available for sale and are carried at fair value, with the change in unrealized gains and losses reported as a separate component on the consolidated statements of operations and comprehensive (loss) income until realized. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. Securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of the excess, if any, is caused by expected credit losses. Expected credit losses on securities are recognized in other (expenses) income, net on the consolidated statements of operations and comprehensive (loss) income, and any remaining unrealized gains and losses are included in accumulated other comprehensive loss on the consolidated statements of stockholders’ equity. For the purposes of computing realized and unrealized gains and losses, the cost of securities sold is based on the specific-identification method. Amortization of discounts and premiums, net, and interest on securities classified as available for sale are included as a component of investment income within other income (expenses). The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include agency mortgage-backed securities, corporate fixed income securities infrequently traded, and other securities, which primarily consist of sovereign debt, U.S. government agency securities, loans, and state and municipal securities. Derivative Financial Instruments The Company enters into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk related to marketable securities. The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in the British Pound Sterling and Australian Dollar. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with marketable securities. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. Outstanding foreign currency derivative contracts in asset and liability positions are recorded at fair value on the consolidated balance sheets within prepaid expenses and other current assets and derivative liability, respectively.

84 Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized in the change in fair value of derivatives within other income (expenses). While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties. Fair Value of Financial Instruments The Company applies the fair value measurement accounting standard whenever other accounting pronouncements require or permit fair value measurements. Fair value is defined in the accounting standard as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy under current accounting guidance prioritizes the inputs to valuation techniques used to measure fair value into three broad levels (Level 1, Level 2, and Level 3). Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability and reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk) in a principal market. Accounts Receivable and Unbilled Receivable, net Accounts receivables are recorded at their estimated net realizable value, and we do not typically charge interest. The allowance for credit losses, known as the Current Expected Credit Losses model, is our best estimate of the amount of probable credit losses associated with our accounts receivable. We determine the allowance based on current conditions, and reasonable and supportable forecasts. Past-due balances and an evaluation of the potential risk of loss associated with the accounts are reviewed individually for collectability. We charge off account balances against the allowance after we have exhausted all means of collection and we consider the potential for recovery to be remote. Our accounts receivable generally have net 30 to net 90-day payment terms, and we usually receive consideration in accordance with the payment terms of the contract. Unbilled receivables arise when the timing of our billing to customers differs from the timing of revenue recognition for the obligations performed. Accounts receivable and unbilled receivable, net consisted of the following as of: (in thousands) December 31, 2024 December 31, 2023 Accounts receivable $ 20,409 $ 15,204 Allowance for credit losses (1,230) — Unbilled receivable — 924 Accounts receivable and unbilled receivable, net $ 19,179 $ 16,128

85 Other Receivables Other receivables consist of amounts due from foreign governmental entities related to the Canadian harmonized sales tax and goods and services tax for goods and services transacted in Canada, and amounts due from cash collateral held by others for foreign currency derivative contracts. Inventory Inventory is stated at the lower of cost or net realizable value. Cost is determined using a weighted-average cost approach, assuming full absorption of direct and indirect manufacturing costs, or based on cost of purchasing from our vendors. If inventory costs exceed expected net realizable value due to obsolescence or lack of demand, valuation adjustments are recorded for the difference between the cost and the expected net realizable value. Inventory consisted of the following as of: (in thousands) December 31, 2024 December 31, 2023 Finished goods $ — $ 24 Raw materials 827 888 Spare parts 39 — Total $ 866 $ 912 Property, Plant, and Equipment Additions to property, plant, and equipment are recorded at cost and depreciated or amortized using the straight- line method over the estimated economic useful lives of the respective assets. The estimated useful lives of assets are as follows: Computer equipment and software 3 years Lab equipment 5 years Furniture, fixtures, and machinery 5 years Leasehold improvements 1-5 years Land improvements and infrastructure 20 years Manufacturing equipment and pilot plant 25 years Land is non-amortizing. Computer equipment and software includes an immaterial amount of internal use software. Major additions and improvements are capitalized, while replacements, repairs, and maintenance that do not extend the life of an asset are charged to expenses. Upon retirement or sale, the cost of assets disposed and the related accumulated depreciation or amortization are removed from the accounts and any resulting gain or loss is charged to income or loss from operations. Costs incurred to acquire, construct or install property, plant, and equipment during the construction stage of a capital project and costs capitalized in conjunction with major improvements that have not yet been placed in service are

86 recorded as construction in progress, and accordingly are not currently being depreciated. The Company capitalizes stock-based compensation expenses and interest cost incurred on funds used to construct property, plant and equipment. Intangible Assets Intangible assets are recorded at cost and are amortized using the straight-line method over the estimated useful lives of the respective assets, ranging from 7 to 15 years. The cost of servicing the Company’s patents is expensed as incurred. Upon retirement or sale, the cost of intangible assets is disposed of and the related accumulated amortization is removed from the accounts. Intangible assets consisted of the following as of: (in thousands) December 31, 2024 December 31, 2023 Patents $ 381 $ 413 Less accumulated amortization (308) (292) Total intangible assets $ 73 $ 121 The weighted average remaining useful life of the patents was 2.41 years as of December 31, 2024. For the years ended December 31, 2024 and 2023, amortization expense was immaterial and annual amortization expense over the remaining useful life is not expected to be material. Held for sale classification Assets are classified as held for sale when management having the authority to approve the action commits to a plan to sell the assets, the sale is probable to occur during the next 12 months at a price that is reasonable in relation to its current fair value and certain other criteria are met. The assets classified as held for sale are recorded at the lower of its carrying amount or estimated fair value less cost to sell. When the proceeds expected to be received from the sale exceed the carrying amount of the assets, a gain is recognized when the sale closes. Assets classified as held for sale are presented separately on the face of the consolidated balance sheets. (See Note 6 for additional details) Impairment of Long-Lived Assets The Company reviews its long-lived assets for impairment whenever events or changes in circumstances indicate that the carrying amounts of the assets may not be fully recoverable. If indicators of impairment exist, management identifies the asset group which includes the potentially impaired long-lived asset, at the lowest level at which there are separate, identifiable cash flows. The determination of recoverability is based on an estimate of undiscounted cash flows expected to result from the use of an asset group and its eventual disposition or its estimated fair value based on the best information available. If the total of the expected undiscounted future net cash flows or the estimated fair value for the asset group is less than the carrying amount of the asset group, a loss is recognized for the difference between the estimated fair value and carrying amount of the asset group. During the year ended December 31, 2024, the Company determined that indicators of impairment existed for the Origin 1 asset group. The significant assumptions used by the Company to determine the undiscounted cash flows expecting to result from the use of Origin 1 included additional capital expenditure requirements, projected revenue, and general operating costs. The Company determined that the estimated undiscounted cash flows were

87 greater than the carrying amount of the long-lived assets related to the Origin 1 asset group. As such, the Company concluded that there was no impairment for the Origin 1 asset group as of December 31, 2024. During the year ended December 31, 2024, the Company determined that indicators of impairment existed for the Origin 2 asset group as it concluded it would not construct a plant on the land owned in Geismar, Louisiana. The Company determined the estimated fair value of the land using appraisal information and determined the estimated fair value of the costs capitalized to construction in progress equated to the costs incurred to date that were not specific to the Geismar, Louisiana land. As a result of the analysis, the Company determined that the estimated fair value of the Origin 2 asset group was $43.1 million, and recorded an impairment charge of $12.3 million to impairment of assets on the consolidated statements of operations and comprehensive (loss) income for the year ended December 31, 2024. Management believes the Origin 2 asset group's remaining costs capitalized to construction in progress of $31.8 million and land held for sale of $11.3 million approximate the total fair value of the asset group as of December 31, 2024. Common Stock Warrants Liability The Company assumed 24,149,960 public warrants (the “Public Warrants”) and 11,326,667 private placement warrants (the “Private Placement Warrants”, and the Public Warrants together with the Private Placement Warrants, the “Common Stock Warrants” or “Warrants”) upon the Merger, all of which were issued in connection with Artius’ initial public offering and entitle each holder to purchase one share of Class A common stock at an exercise price of at $11.50 per share. As of December 31, 2024 and 2023, 24,149,960 Public Warrants and 11,326,667 Private Placement Warrants are outstanding. The Public Warrants are publicly traded and are exercisable for cash unless certain conditions occur, such as the failure to have an effective registration statement related to the shares issuable upon exercise or redemption by the Company under certain conditions, at which time the Public Warrants may be cashless exercised. The Private Placement Warrants are transferable, assignable or salable in certain limited exceptions. The Private Placement Warrants are exercisable for cash or on a cashless basis, at the holder’s option, and are non-redeemable so long as they are held by the initial purchasers or their permitted transferees. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will cease to be Private Placement Warrants, and become Public Warrants and be redeemable by the Company and exercisable by such holders on the same basis as the other Public Warrants. There were no Private Placement Warrants that became Public Warrants through December 31, 2024. The Company evaluated the Common Stock Warrants under ASC 815-40, Derivatives and Hedging-Contracts in Entity’s Own Equity (“ASC 815-40”), and concluded they do not meet the criteria to be classified in stockholders’ equity. Specifically, the exercise of the Common Stock Warrants may be settled in cash upon the occurrence of a tender offer or exchange that involves 50% or more of our Class A stockholders. Because not all of the voting stockholders need to participate in such tender offer or exchange to trigger the potential cash settlement and the Company does not control the occurrence of such an event, the Company concluded that the Common Stock Warrants do not meet the conditions to be classified in equity. Since the Common Stock Warrants meet the definition of a derivative under ASC 815, the Company recorded these Warrants as liabilities on the consolidated balance sheets at fair value, with subsequent changes in their respective fair values recognized in the gain in fair value of common stock warrant liabilities within the consolidated statements of operations and comprehensive (loss) income at each reporting date. The Public Warrants were publicly traded and thus had an observable market price to estimate fair value, and the Private Placement Warrants were effectively valued similar to the Public Warrants, as described in Note 5.

88 Earnout Liability The Company has recorded an earnout liability related to future contingent equity shares related to the Merger (Note 9 for additional details). The Company recorded these instruments as liabilities on the consolidated balance sheets at fair value, with subsequent changes in their respective fair values recognized in earnings at each reporting date. Leases We determine if an arrangement is a lease at inception. Where an arrangement is a lease, we determine if it is an operating lease or a finance lease. The Company has leases for office space and equipment, some of which have escalating rentals during the initial lease term and during subsequent optional renewal periods. The Company accounts for its leases under ASC 842, Leases. The Company recognizes an ROU asset and lease liability for leases based on the net present value of future minimum lease payments. Lease expense is recognized on a straight-line basis over the non-cancelable lease term and renewal periods that are considered reasonably certain to be exercised. Certain operating leases contain options to extend the lease. The Company included the periods covered by these options as we are reasonably certain to exercise the options for all leases. For leases with the option to extend on a month-to-month basis after the defined extension periods, the Company is reasonably certain to extend for the same term as related leases. As such, lease terms for all leased assets located at the same locations have the same end dates. Rent deposits relating to leases are included within other long-term assets on the consolidated balance sheets. Variable lease costs include operating expenses for the shared common area, and the amount is based on an annual estimate of the actual common area expenses from the preceding year and are payable monthly. The Company elected the accounting policy election to account for lease and nonlease components as a single lease component for all asset classes. Further, the Company elects to recognize lease payments on short-term leases in profit or loss on a straight-line basis over the lease term for all asset classes, excluding such leases from recognition requirements under ASC 842. To calculate the ROU assets and lease liabilities, the Company uses the discount rate implicit in lease agreements when available. When the implicit discount rates are not readily determinable, the Company uses the incremental borrowing rate, determined as of the later of the date of adoption for ASC 842, date of lease inception or date of lease modification. This rate is determined for individual leases based on available information regarding jurisdiction, lease term, and asset class. Further, the interest environment was considered, including analysis of benchmark rates from promissory notes, credit curve yields for bonds, and synthetic curves based on discount margin spreads. Revenue Recognition Our revenues are from product sales and service agreements. The majority of our contracts with customers typically contain multiple products and services. We account for individual products and services separately if they are distinct—that is, if a product or service is separately identifiable from other items in the contract and if a customer can benefit from it on its own or with other resources that are readily available to the customer. The Company recognizes revenue in accordance with ASC 606, Revenue from Contracts with Customers (“ASC 606”). The core principle of ASC 606 requires that an entity recognize revenue to depict the transfer of promised goods or service to customers in an amount that reflects the consideration to which the Company expects to be entitled in exchange for those goods or services. In determining the appropriate amount of revenue to be recognized as we fulfill our obligations under our product revenue and service agreements, we perform the

89 following steps: 1. Identifying the contract with a customer; 2. Identifying the performance obligations in the contract; 3. Determining the transaction price; 4. Allocating the transaction price to the performance obligations; and 5. Recognizing revenue when, or as, the performance obligations are satisfied. We account for a contract with a customer when there is approval and commitment from both parties, the rights of the parties are identified, payment terms are identified, the contract has commercial substance and collectability of consideration is probable. Non-cancellable purchase orders received from customers to deliver a specific quantity of product, when combined with our order confirmation, in exchange for future consideration, create enforceable rights and obligations on both parties and constitute a contract with a customer. Our service agreements are customized, specified, and often include various stages at which transaction prices are agreed to. These service agreements often include multiple performance obligations within each stage. We identify each performance obligation at contract inception and allocate the consideration to each distinct performance obligation based on the stand-alone selling price of each performance obligation. Our services are tailored to each individual customer and the stand-alone selling prices are not directly observable. As our service agreements include customers that are not in similar geographic markets and for different services, therefore the Company uses the expected cost plus margin approach to estimate the stand-alone selling price for each of our performance obligations. We recognize revenue from the service agreements over the period during which the services are performed and recognize the associated costs as they are incurred. In general, we recognize revenue when, or as, our performance obligations under the terms of a contract with our customer are satisfied. For product sales, this happens when we transfer control of our products and risk of loss to the customer or when title passes upon shipment. Revenue is measured as the amount of consideration we expect to receive in exchange for transferring our products. Taxes collected from customers and remitted to governmental authorities are excluded from revenues. The Company recognizes its revenue from direct product sales which is recognized at a point in time when the performance obligation is satisfied upon delivery of the product. For service agreements, the timing of satisfying performance obligations may differ from the timing of the invoicing of customers and the receipt of customer payments. The Company records a receivable prior to payment if there is an unconditional right to payment. Alternatively, when payment precedes the provision of the related services, the Company records contract liability (deferred revenue) until the performance obligations are satisfied. Revenue is recorded in an amount that reflects that consideration we expect to be entitled to in exchange for those goods or services. We have elected to treat shipping and handling activities as fulfillment costs. Cost of revenues Cost of revenues for product sales consists primarily of cost associated with the purchase of finished goods. Cost of revenues for service agreements is based on the actual cost incurred, which mainly consists of the direct cost from vendors and overhead costs such as payroll and benefit related to our employees who provide the services to customers.

90 Research and Development Cost Costs related to research and development are expensed as incurred. Stock-Based Compensation The Company has issued common stock awards under three equity incentive plans. Origin measures stock options and other stock-based awards granted to employees, directors and other service providers based on their fair value on the date of grant and recognizes compensation expenses of those awards over the requisite service period, which is generally the vesting period of the respective award. In addition, the Company capitalizes stock-based compensation related to employees whose costs are necessary to bring the asset to its intended use. For awards with performance conditions, compensation is recorded once there is sufficient objective evidence the performance conditions are considered probable of being met. Origin applies the straight-line method of expense recognition to all awards with only service-based vesting conditions. Origin estimates the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model and the grant date closing stock price for restricted stock unit (“RSU”) awards and PSU awards. The Black-Scholes option-pricing model requires the use of highly subjective assumptions including: • Expected term – The expected term of the options is based on the simplified method, which takes into consideration the grant’s contractual life and vesting period and assumes that all options will be exercised between the vesting date and the contractual term of the option which averages an award’s vesting term and its contractual term. • Expected volatility – The Company uses the trading history of various companies in its industry sector in determining an estimated volatility factor. • Expected dividend – The Company has not declared common stock dividends and does not anticipate declaring any common stock dividends in the foreseeable future. • Forfeiture – The Company estimates forfeitures based on historical activity and considers voluntary and involuntary termination behavior as well as analysis of actual historical option forfeitures, netting the estimated expense by the derived forfeiture rate. • Risk-free interest rate – The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with the same or substantially equivalent remaining term. Workforce Reduction Costs In September 2024 and November 2023, we announced workforce reductions of approximately 28% and 30%, respectively, of our workforce to realign with our refined corporate strategy. This organizational realignment reflects the deferral of research programs with longer-term economic impacts and the acceleration of higher margin revenue opportunities. Workforce reduction costs primarily consisted of severance and benefits costs associated with the workforce reduction (see Note 12 for additional details). Income Taxes Deferred income taxes are determined using the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the

91 differences are expected to reverse. A valuation allowance is recorded when the expected recognition of a deferred income tax asset is considered to be unlikely. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters as a component of income tax expense. Functional Currency Translation The functional currency of the Company’s wholly-owned Canadian subsidiaries is the Canadian dollar, whereby their assets and liabilities are translated at period-end exchange rates except for non-monetary capital transactions and balances, which are translated at historical rates. All income and expense amounts of the Company are translated at average exchange rates for the respective period. Translation gains and losses are not included in determining net (loss) income but are accumulated in a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in the determination of net (loss) income in the period in which they occur. These amounts are included in other (expenses) income, net, on the consolidated statements of operations and comprehensive (loss) income. Comprehensive (Loss) Income The Company’s comprehensive (loss) income consists of net (loss) income and Other comprehensive income (loss). Foreign currency translation gains or losses and unrealized gains or losses on available-for-sale marketable debt securities are included in the Company’s Other comprehensive income (loss). Basic and Diluted Net (Loss) Income Per Share Basic net (loss) income per common share is calculated by dividing the net (loss) income attributable to common stockholders by the weighted-average number of common shares outstanding during the period, without consideration of potentially dilutive securities. Diluted net (loss) income per share is computed by dividing the net (loss) income attributable to common stockholders by the weighted-average number of common stock and potentially dilutive securities outstanding for the period. For the purposes of the diluted net (loss) income per share calculation, common stock options, RSU awards, performance stock awards, warrants, earnout shares, and Sponsor Vesting Shares (as defined in Note 9) are considered to be potentially dilutive securities. For the periods presented that the Company has reported a net loss, diluted net loss per common share is the same as basic net loss per common share for those periods. Reclassification Certain amounts on the consolidated statement of cash flows for the year ended December 31, 2023 have been condensed to conform with the current presentation for the year ended December 31, 2024.

92 3. Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, Segment Reporting (“Topic 280”) - Improvements to Reportable Segment Disclosures, which amends the existing segment reporting guidance (Topic 280) to improve reportable segment disclosure requirements, primarily through enhanced disclosures about significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”) and included within each reported measure of segment profit or loss, an amount for other segment items by reportable segment and a description of its composition, the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. All disclosure requirements of ASU 2023-07 are required for entities with a single reportable segment. The Company adopted the new standard for the year ended December 31, 2024 for annual and retrospective reporting periods with all interim disclosures to begin in the first quarter of the year ending December 31, 2025. The adoption of the standard had no material impact on the Company’s financial position, results of operations or cash flows, but did result in new and expanded segment disclosures. The Company has included such disclosures in Note 13. Recently Issued Accounting Pronouncements Not Yet Adopted as of December 31, 2024 In December 2023, the FASB issued ASU 2023-09, Income Taxes (“Topic 740”) - Improvements to Income Tax Disclosures, which modifies the rules on income tax disclosures to require entities to disclose (1) specific categories in the rate reconciliation, (2) the income or loss from continuing operations before income tax expense or benefit (separated between domestic and foreign) and (3) income tax expense or benefit from continuing operations (separated by federal, state and foreign). ASU 2023-09 also requires entities to disclose their income tax payments to international, federal, state and local jurisdictions, among other changes. The guidance should be applied on a prospective basis however a retrospective application is permitted. The guidance is effective for the Company for annual periods beginning after December 15, 2024. The Company adopted the new standard as of January 1, 2025. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements, other than additional disclosures in our notes to the consolidated financial statements. In November 2024, the FASB issued ASU 2024-03, Income Statement-Reporting Comprehensive Income- Expense Disaggregation Disclosures (Subtopic 220-40), to enhance the transparency and decision usefulness of financial information presented in the income statement by requiring disaggregated information about certain income statement expense line items. ASU 2024-03 is effective for annual periods beginning after December 15, 2026, and interim reporting periods beginning after December 15, 2027, and early adoption is permitted. The Company does not expect that the adoption of this guidance will have a material impact on its consolidated financial statements, other than additional disclosures in our notes to the consolidated financial statements. The Company has determined that all other recently issued accounting pronouncements will not have a material impact on the Company’s consolidated financial statements or do not apply to its operations. 4. Revenues We recognize revenues when, or as, our performance obligations under the terms of a contract with our customer are satisfied (see Note 2 for additional details). We generally procure, will produce, and sell product to be utilized

93 in the manufacturing of finished products, for which we recognize revenue upon shipment. Currently, the majority of our revenue is generated from the supply chain activation program in which the Company purchases materials from various vendors and sells them to our customers for a moderate margin as we establish the logistics and invoicing capabilities for our own products. Our service contracts generally pay us at the commencement of the agreement and then at additional intervals as outlined in each contract. We recognize contract liabilities for such payments and then recognize revenue as we satisfy the related performance obligations. To the extent collectible revenue recognized under this method exceeds the consideration received, we recognize contract assets for such unbilled consideration. We recognize revenue from the service agreements over the period during which the services are performed. The Company did not receive payment before the provision of services for the years ended December 31, 2024 and 2023. Therefore, deferred revenue was zero as of December 31, 2024 and 2023. 5. Fair Value Measurement The Company’s financial assets and liabilities subject to fair value measurements on a recurring basis and the level of inputs used for such measurements were as follows: Fair Value as of December 31, 2024 (in thousands) Level 1 Level 2 Level 3 Total Assets: Cash equivalents $ 46,953 $ — $ — $ 46,953 Marketable securities — 46,613 — 46,613 Derivative asset — 15 — 15 Total fair value $ 46,953 $ 46,628 $ — $ 93,581 Liabilities: Common stock warrants (Public) $ 3,108 $ — $ — $ 3,108 Common stock warrants (Private Placement) — 1,458 — 1,458 Earnout liability — — 2,486 2,486 Total fair value $ 3,108 $ 1,458 $ 2,486 $ 7,052

94 Fair Value as of December 31, 2023 (in thousands) Level 1 Level 2 Level 3 Total Assets: Cash and cash equivalents $ 75,502 $ — $ — $ 75,502 Marketable securities — 82,761 — 82,761 Total fair value $ 75,502 $ 82,761 $ — $ 158,263 Liabilities: Common stock warrants (Public) $ 913 $ — $ — $ 913 Common stock warrants (Private Placement) — 428 — 428 Earnout liability — — 1,783 1,783 Derivative liability — 300 — 300 Total fair value $ 913 $ 728 $ 1,783 $ 3,424 The Company performs routine procedures such as comparing prices obtained from independent sources to ensure that appropriate fair values are recorded. The cash equivalents and Public Warrants are categorized as Level 1 instruments as the fair value was determined based on the unadjusted quoted prices are available in active markets for identical assets or liabilities as of the reporting date. The marketable securities, derivative asset and derivative liability are categorized as Level 2 instruments as the estimated fair value was determined based on the estimated or actual bids and offers of the marketable securities in an over-the-counter market on the last business day of the year. The Private Placement Warrants are classified within Level 2 because the transfer of Private Placement Warrants to anyone outside of certain permitted transferees of Artius Acquisition Partners LLC (the “Sponsor”) would result in the Private Placement Warrants having substantially the same terms as the Public Warrants, the Company determined that the fair value of each Private Placement Warrant is consistent with that of a Public Warrant. Accordingly, the Private Placement Warrants are classified as Level 2 financial instruments. The value of the earnout liability is classified as Level 3 measurements under the fair value hierarchy, as these liabilities have been valued based on significant inputs not observable in the market (see Note 9 for additional details). A loss of $0.7 million and a gain of $41.0 million for the years ended December 31, 2024 and 2023, respectively, was recorded on the consolidated statements of operations and comprehensive (loss) income in the (loss) gain in fair value of earnout liability.

95 The following table summarizes the activities for the earnout liability for the years ended: (in thousands) December 31, 2024 December 31, 2023 Balance at beginning of year $ 1,783 $ 42,533 Loss (gain) in fair value of earnout liability 703 (40,983) Other — 233 Balance at end of year $ 2,486 $ 1,783 As of December 31, 2024 and 2023, the carrying values of accounts receivable and unbilled receivable, other receivables, accounts payable, and accrued expenses approximate their respective fair values due to their short- term nature. We have determined the fair value of notes payable and Canadian government research and development program liability approximates the carrying value due to the standard terms of the arrangement including but not limited to the amount borrowed, the term, and the interest rate. Marketable Securities The Company’s marketable securities that are measured at fair value on a recurring basis and are categorized using the fair value hierarchy. Amortized cost net of unrealized gain (loss) is equal to fair value. The following table summarizes the marketable securities by major security type as follows: As of December 31, 2024 (in thousands) Amortized Cost Unrealized Gains Unrealized Losses Fair Value Corporate bonds $ 3,741 $ 30 $ — $ 3,771 Asset-backed securities 36,309 39 (1,349) 34,999 U.S. government and agency securities 7,829 14 — 7,843 Total marketable securities $ 47,879 $ 83 $ (1,349) $ 46,613

96 As of December 31, 2023 (in thousands) Amortized Cost Unrealized Gains Unrealized Losses Fair Value Corporate bonds $ 21,869 $ 26 $ (847) $ 21,048 Asset-backed securities 52,199 26 (2,289) 49,936 U.S. government and agency securities 11,706 — (270) 11,436 Foreign government and agency securities 372 — (31) 341 Total marketable securities $ 86,146 $ 52 $ (3,437) $ 82,761 The realized gains and losses are included in other (expenses) income, net in the consolidated statements of operations and comprehensive (loss) income. We sold marketable securities for proceeds of $1,751.5 million and $3,605.2 million for the years ended December 31, 2024 and 2023, respectively. As a result of those sales, we realized a loss of $0.9 million and a gain of $1.0 million for the years ended December 31, 2024 and 2023, respectively. We regularly review our available- for-sale marketable securities in an unrealized loss position and evaluate the current expected credit loss by considering factors such as historical experience, market data, issuer-specific factors, and current economic conditions. The aggregate fair value of the marketable securities in an unrealized loss position was $26.6 million and $73.2 million as of December 31, 2024 and 2023, respectively. The unrealized losses were attributable to changes in interest rates that impacted the value of the investments, and not related to increased credit risk. Accordingly, we have not recorded an allowance for credit losses associated with these investments. The contractual maturities of the investments classified as marketable securities are as follows: As of December 31, 2024 (in thousands) Mature within one year Mature after one year through two years Mature over two years Fair Value Corporate bonds $ — $ 2,869 $ 902 $ 3,771 Asset-backed securities — — 34,999 34,999 U.S. government and agency securities 5,984 — 1,859 7,843 Total marketable securities $ 5,984 $ 2,869 $ 37,760 $ 46,613

97 As of December 31, 2023 (in thousands) Mature within one year Mature after one year through two years Mature over two years Fair Value Corporate bonds $ 20,756 $ 292 $ — $ 21,048 Asset-backed securities 238 1,806 47,892 49,936 U.S. government and agency securities 8,929 — 2,507 11,436 Foreign government and agency securities 341 — — 341 Total marketable securities $ 30,264 $ 2,098 $ 50,399 $ 82,761 Derivative Asset and Liabilities The Company entered into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk related to certain marketable securities denominated in foreign currency. Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other income (expenses). For the years ended December 31, 2024 and 2023, the Company recognized a net gain of $0.3 million and $0.1 million, respectively, on the fair value adjustment of the foreign currency derivative contracts. The notional amount of foreign currency derivative contracts as of December 31, 2024 and 2023 was $1.2 million and $14.7 million, respectively.

98 6. Property, Plant and Equipment Property, plant, and equipment consisted of the following as of: (in thousands) December 31, 2024 December 31, 2023 Land $ 56 $ 11,356 Land improvements and infrastructure 58,452 62,930 Manufacturing equipment and pilot plant 111,053 116,754 Computer equipment and software 2,726 1,629 Lab equipment 3,496 3,468 Furniture, fixtures, and machinery 372 1,094 Leasehold improvements 4,765 — Total 180,920 197,231 Less accumulated depreciation and amortization (17,332) (8,136) Construction in progress 40,331 54,023 Total property, plant, and equipment, net $ 203,919 $ 243,118 For the years ended December 31, 2024 and 2023, depreciation and amortization expense totaled $10.7 million and $3.3 million, respectively. During the years ended December 31, 2024 and 2023, the Company capitalized zero and $1.5 million, respectively, of interest cost into property, plant and equipment related to Origin 1, and also capitalized, zero and $2.3 million, respectively, of stock-based compensation related to employees whose costs were necessarily incurred to bring the asset to its intended use. Interest and stock-based compensation costs capitalization ceased during the fourth quarter of 2023 as Origin 1 was completed. As of December 31, 2024, the land purchased in Geismar, Louisiana in 2022 met the criteria to be presented as asset held for sale. It is the Company's intention to complete the sale of the land within the next 12 months. The carrying value of $11.3 million, classified as land held for sale, was included in total current assets in the consolidated balance sheets.

7 7. Notes Payable Legacy Origin received a $5.0 million prepayment from a legacy stockholder for product from Origin 1 pursuant to one of these Offtake Agreements, which Legacy Origin entered into in November 2016. The prepayment was to be credited against the purchase of products over the term of the Offtake Agreement. The prepayment was secured by a promissory note (the “Promissory Note”) to be repaid in cash in the event that the prepayment could not be credited against the purchase of product, for example, if Origin 1 was never constructed. The Promissory Note was collateralized substantially by Origin 1 and other assets of Origin Materials Canada Pioneer Limited. In May 2019, Legacy Origin and the legacy stockholder amended the Offtake Agreement and Promissory Note. The amendment added accrued interest of $0.2 million to the principal balance of the prepayment and provided for the prepayment amount to be repaid in three annual installments rather than being applied against the purchase of product from Origin 1. On August 1, 2022, the Company and the legacy stockholder further amended and restated the Promissory Note with an aggregate principal amount of $5.2 million, which is the sum of the original principal with accrued interest prior to the amendment. As a result of the amendment, the repayment dates were revised and to allow the legacy stockholder to offset amounts owed for the purchase of product from the Company’s Origin 1 facility against amounts due under the Promissory Note. A repayment of $2.7 million was paid during 2024, $1.9 million is due on September 1, 2025, and $1.8 million is due on September 1, 2026 (inclusive of accrued but unpaid interest of 3.5% per annum). At December 31, 2024, the outstanding note principal balance was $3.5 million, of which $1.7 million was included in notes payable, long-term, and $1.8 million in notes payable, short-term, and unpaid accrued interest of less than $0.1 million was recorded in other liabilities, current. At December 31, 2023, the total note principal outstanding was $5.2 million, of which $3.5 million was included in notes payable, long-term, and $1.7 million in notes payable, short-term, and unpaid accrued interest of $0.8 million was recorded in other liabilities, current. In addition, the amendment reflected the legacy stockholder’s exercise of its option to enter into a new Offtake Agreement to buy a specified annual amount of product from Origin 2 for an initial term of up to 10 years. Legacy Origin received a $5.0 million prepayment from a legacy stockholder for product from Origin 1 pursuant to an Offtake Agreement entered into in November 2016. The agreement was amended in 2019 and added the accrued interest of $0.1 million to the principal balance. As a result, the aggregate principal amount became $5.1 million. The prepayment was to be credited against the purchase of products from Origin 1 over the term of the Offtake Agreement, specifically, by applying a credit to product purchases each month over the first five years of operation of Origin 1 up to $7.5 million, which is equal to 150% of the prepayment amount. If product purchases are not sufficient to recover the advances, the application of the credit to purchases as payment of the advances would continue until fully repaid. The prepayment is secured by an agreement that was to be repaid in cash in the event the prepayment cannot be credited against the purchase of product, for example, if Origin 1 were never constructed. The agreement is collateralized substantially by Origin 1 and other assets of Origin Material Canada Pioneer Limited. If repaid in cash, the agreement bears an annual interest rate of the three-month Secured Overnight Financing Rate (“SOFR”) plus 0.25% (4.94% at December 31, 2024) and matures five years from the commercial operation date of Origin 1, which is defined by the plant's actual production of a certain volume of product as well as its capacity to produce a certain annual volume of product. In February 2024, the Company and the legacy stockholder amended the agreement to provide for repayment with interest accrual in three installments consisting of approximately $2.2 million on March 1, 2024, $1.6 million on September 1, 2024, and $2.1 million on March 1, 2025 instead of applying a credit to product purchases under the Offtake Agreement. As a result, the principal amounts outstanding under the agreement were reclassified from other liabilities, long-term to notes payable, short-term and the accrued interest was reclassified from other liabilities, long-term to other liabilities, current during the year ended December 31, 2024. The outstanding principal of $2.0 million at

8 December 31, 2024 was recorded in notes payable, short-term and less than $0.1 million accrued interest outstanding was recorded in other liabilities, current. The remaining outstanding balance, with interest, was paid in March 2025. At December 31, 2023, the total amount outstanding of $5.1 million and accrued interest outstanding of $0.6 million was recorded in other liabilities, long-term. 8. Other Liabilities In September 2019, Legacy Origin entered into a $5.0 million prepayment agreement with a counterparty for the purchase of products from Origin 1. The prepayment is to be made in two equal installments: the first $2.5 million was paid in October 2019 and the remaining $2.5 million is due within 30 days of the customer confirming that a sample from Origin 1 meets the customer’s specifications. The Company and customer agreed to work in good faith to execute an Offtake Agreement, the agreed terms of which are set forth in the prepayment agreement, whereby 100% of the prepayment will be applied against future purchases. The prepayment agreement provides the customer a capacity reservation of up to a specified annual volume of product from Origin 1 for a term of ten years, pursuant to the terms of an Offtake Agreement. At December 31, 2024 and 2023, the total amount outstanding on this agreement was $2.5 million. On February 5, 2024, the parties entered into a MOU by which they agreed that the counterparty would be released from its obligation to pay the remaining $2.5 million of the prepayment and that the Company would refund the first $2.5 million within a certain period after reporting in its Quarterly Report on Form 10-Q that its cash and cash equivalents has fallen below a specified threshold. In November 2024, the parties entered into a second MOU providing for the return of the counterparty's first prepayment, without regard to cash on hand, termination of the prepayment agreement, and a waiver of each party's rights, claims, and demands associated with that agreement. The $2.5 million prepayment was included in other liabilities, current as of December 31, 2024 and in other liabilities, long-term as of December 31, 2023. We returned the prepayment on February 28, 2025. 9. Earnout Liability As additional consideration for the Merger, within ten business days after the occurrence of a “Triggering Event,” as defined below, the Company shall issue or cause to be issued to each Legacy Origin stockholder a certain number of shares of the Company Class A Common Stock. The number of such shares is equal to the product of (i) the number of shares of Company Common Stock, Company Series A Preferred Stock, Company Series B Preferred Stock, Company Series C Preferred Stock, and the net number of shares of Company Capital Stock that would be issuable in respect of “Vested Company Options” in the event such options were exercised (on a net exercise basis with respect to only the applicable exercise price, immediately prior to the “Closing” and settled in the applicable number of shares of Company Common Stock, rounded down to the nearest whole share) held by such Legacy Origin stockholder as of immediately prior to the “Effective Time”; and (ii) the “Earnout Exchange Ratio” (such issued shares of Artius Class A Common Stock, collectively, the “Earnout Shares”), where “Vested Company Options,” “Closing,” “Effective Time,” and “Earnout Exchange Ratio” have the meanings set forth in the Merger Agreement. The Company cannot be required to issue more than 25,000,000 Earnout Shares in the aggregate. Additionally, such Earnout Shares will also become issuable in the event the Company enters into a definitive agreement with respect to an Artius Sale (as defined in the Merger Agreement) on or before the fifth anniversary of the Closing Date. A Triggering Event is defined as the following: (a) the volume weighted average price of Common Stock (“VWAP”) equaling on exceeding $15.00 for ten consecutive trading days during the three year period following the closing date of June 25, 2021, ending June 25, 2024;

76 (b) the VWAP equaling or exceeding $20.00 for ten consecutive trading days during the four year period following the closing date, ending June 25, 2025; or (c) the VWAP equaling or exceeding $25.00 for ten consecutive trading days during the five year period following the closing date, ending June 25, 2026. A Sponsor Letter Agreement was delivered in connection with the Merger such that 4,500,000 of the shares held by Sponsor (“Sponsor Vesting Shares”) shall be subject to forfeiture based on the same vesting requirements as the Earnout Shares. The first Triggering Event was not met by its June 25, 2024 deadline and 1,500,000 shares were cancelled. As a result, there were 3,000,000 Sponsor Vesting Shares remaining and the value of Sponsor Vesting Shares in the earnout liability balance was reduced accordingly. These shares shall not be transferred prior to the date in which they vest. Dividends and other distributions with respect to Sponsor Vesting Shares shall be set aside by the Company and shall be paid to the Sponsor upon the vesting of such Sponsor Vesting Shares. The Company evaluated the earnout liability under ASC 815-40, Derivatives and Hedging-Contracts in Entity’s Own Equity (“ASC 815-40”), and concluded they do not meet the criteria to be classified in stockholders’ equity. Specifically, there are contingent exercise provisions and settlement provisions that exist. Holders may receive differing amounts of shares depending on the company’s stock price or the price paid in a change of control. All remaining shares would be issuable (or the forfeiture provisions would lapse) upon any change of control involving the Company and all remaining shares would be issuable (or the forfeiture provisions would lapse) upon a bankruptcy or insolvency of the company. This means that settlement is not solely impacted by the share price of the Company (that is, the share price observed in or implied by a qualifying change-in-control event), but also by the occurrence of a qualifying change-in-control event. This causes the arrangement to not be indexed to the Company’s own shares and liability classification is appropriate. The Company records these instruments as liabilities on the consolidated balance sheets at fair value, with subsequent changes in their respective fair values recognized in earnings at each reporting date. The earnout liability was fair valued using a Monte Carlo open- ended model. The inputs used for the model were a dividend yield of 0% and 0%, volatility of 136% and 108%, and interest rate of 4.12% and 4.04% at December 31, 2024 and 2023, respectively. 10. Canadian Government Research and Development Program Liability In April 2019, the Company entered into a contribution agreement related to the research and development and construction associated with the operation of Origin 1 in which the Company will participate in a Canadian government research and development program (the “R&D Agreement”). Pursuant to the R&D Agreement, the Company will receive funding for eligible expenditures incurred through March 31, 2023 up to the lesser of approximately 18.48% of eligible costs and $23.0 million (in Canadian dollars). The funding will be repaid over 15 years after completion of Origin 1, commencing no sooner than the third fiscal year of consecutive revenues from a commercial plant, but no later than March 2028. The maximum amount to be repaid by the Company under the R&D Agreement is 1.25 times the actual funding received, subject to the following repayment ceiling formula. Once begun, repayments will be paid annually by April of each year through March 31, 2037. Payments will be determined by a formula of the funded amount based on the fiscal year gross business revenue, as defined in the R&D Agreement. The Company received $8.1 million and zero for the years ended December 31, 2024 and 2023, respectively, related to the eligible expenditures incurred before March 31, 2023.

77 11. Common Stock Warrants As of December 31, 2024 and 2023, there are 35,476,627 warrants outstanding. As part of Artius’s initial public offering, 24,149,960 Public Warrants were sold. The Public Warrants entitle the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustments. The Public Warrants may be exercised only for a whole number of shares of Common Stock. No fractional shares will be issued upon exercise of the Public Warrants. The Public Warrants will expire on June 25, 2026 at 5:00p.m., New York City time, or earlier upon redemption or liquidation. The Public Warrants are listed on the Nasdaq under the symbol “ORGNW.” The Company may redeem the Public Warrants when exercisable, in whole and not in part, at a price of $0.01 per warrant, so long as the Company provides not less than 30 days’ prior written notice of redemption to each warrant holder, and if, and only if, the reported last sale price of the Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date the Company sends the notice of redemption to the warrant holders. Simultaneously with Artius’s initial public offering, Artius consummated a private placement of 11,326,667 Private Placement Warrants with the Sponsor. The Private Placement Warrant is exercisable for one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. The Private Placement Warrant expires on June 25, 2026 or earlier upon redemption or liquidation. The Private Placement Warrants are identical to the Public Warrants, except that: (1) the Private Placement Warrants and the shares of Class A Common Stock issuable upon exercise of the Private Placement Warrants are not transferable, assignable or salable until the earliest to occur of: (i) 365 days after the date of the Closing; (ii) the first day after the date on which the closing price of the Public Shares (or any successor securities thereto) equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30- trading day period commencing at least 150 days after the date of the Closing; or (iii) the date on which Artius completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of Artius’s Public Shareholders having the right to exchange their Public Shares (or any successor securities thereto) for cash, securities or other property, subject to certain limited exceptions, (2) the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except if the reference value equals or exceeds $10.00 and is less than $18.00 (as described above), so long as they are held by the initial purchasers or their permitted transferees, and (3) the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will be entitled to registration rights. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable under all redemption scenarios by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company concluded the Public Warrants and Private Placement Warrants, or Common Stock Warrants, meet the definition of a derivative under ASC 815 and are recorded as liabilities. Upon consummation of the Merger, the fair value of the Common Stock Warrants was recorded on the consolidated balance sheets. The fair value of the Common Stock Warrants was remeasured as of December 31, 2024 and 2023 (see Note 5 for additional details), and a loss of $3.2 million and a gain of $29.5 million, respectively, was recorded on the consolidated statements of operations and comprehensive (loss) income.

78 12. Stockholders’ Equity Common Stock Holders of the Common Stock are entitled to dividends when, as, and if, declared by the Board, subject to the rights of the holders of all classes of stock outstanding having priority rights to dividends. As of December 31, 2024, the Company had not declared any dividends. The holder of each share of Common Stock is entitled to one vote. Employee Stock Purchase Plan The Company maintains an Employee Stock Purchase Plan (“ESPP”). The ESPP permits participants to purchase shares of our Common Stock with the purchase price of the shares at a price determined by our Board, which shall not be less than 85% of the lower of the fair market value of our Common Stock on the first day of an offering or on the date of purchase. Initially, following adoption of the ESPP, the maximum number of shares of our Common Stock that may be issued under the ESPP was 1,846,710. The ESPP contains an “evergreen” share reserve feature that automatically increases the number of shares of Common Stock reserved for issuance under the plan on January 1 of each year for a period of ten years commencing on January 1, 2022 and ending on (and including) January 1, 2031 in an amount equal to the lesser of (1) one percent (1%) of the fully-diluted shares of our Common Stock on December 31st of the preceding calendar year, (2) 3,693,420 of Common Stock, or (3) such lesser number of shares as determined by our Board. As of December 31, 2024, the number of shares available for issuance under the ESPP was 5,639,944. Our Board made the decision not to increase the number of shares of Common Stock reserved for issuance under the ESPP as of January 1, 2024 as no stock has been offered or issued to employees under the ESPP to date. Shares subject to purchase rights granted under the ESPP that terminate without having been exercised in full will not reduce the number of shares available for issuance under the ESPP. Equity Incentive Plans The Company maintains the following equity incentive plans: the 2010 Stock Incentive Plan, the 2020 Equity Incentive Plan, and the 2021 Equity Incentive Plan, each as amended (together, the “Stock Plans”). Upon closing of the Merger, awards under the 2010 Stock Incentive Plan and 2020 Equity Incentive Plan were converted at the Exchange Ratio, which has the meaning set forth in the Merger Agreement, and the 2021 Equity Incentive Plan was adopted and approved. Origin may grant a wide variety of equity securities under the Stock Plans, including incentive stock options, nonstatutory stock options, stock appreciation rights, restricted stock awards, RSU awards, PSU awards, and other awards. The Company has granted incentive stock options, RSU awards, and PSU awards under the Stock Plans. Under the Stock Plans, options must be issued at exercise prices no less than the estimated fair value of the stock on the date of grant and are exercisable for a period not exceeding 10 years from the date of grant. Options granted to employees under the Stock Plans generally vest 25% one year from the vesting commencement date and 1/36th per month thereafter, although certain arrangements call for vesting over other periods. Options granted to non- employees under the Stock Plan vest over periods determined by the Board (generally immediate to four years). RSU awards granted to employees under the 2021 Equity Incentive Plan require a service period of three years and generally vest 33.3% annually over the three-year service period. Under the Stock Plans, the fair value of RSU awards and PSU stock awards are determined to be the grant date closing stock price. For awards with

79 performance-based conditions, compensation is recorded once there is sufficient objective evidence the performance conditions are considered probable of being met. The PSU stock awards are subject to vesting based on a performance-based condition and a service-based condition. The PSU stock awards will vest in a percentage of the target number of shares between 0% and 300%, depending on the extent the performance conditions are achieved. Initially, following adoption of the 2021 Equity Incentive Plan, there were 18,467,109 shares of Common Stock reserved for issuance under the Stock Plans. The 2021 Equity Incentive Plan contains an “evergreen” share reserve feature that automatically increases the number of shares of Common Stock reserved for issuance under the plan on January 1 of each year for a period of ten years commencing on January 1, 2022 and ending on (and including) January 1, 2031 in an amount equal to five percent (5%) of the fully-diluted Common Stock on December 31 of the preceding year unless our Board acts prior to January 1 to increase the share reserve by a lesser amount. The number of shares added to the share reserve on January 1 of a given year is reduced automatically to the extent necessary to avoid causing the share reserve to exceed fifteen percent (15%) of the fully-diluted Common Stock on December 31 of the preceding year. As of December 31, 2024, the number of shares available for issuance under the 2021 Equity Incentive Plan was 30,040,212. On January 1, 2025, the number of shares of Common Stock reserved for issuance under the 2021 Equity Incentive Plan was automatically increased by 712,137 shares pursuant to the 2021 Equity Incentive Plan’s “evergreen” provision to a total of 30,752,349 shares. As of December 31, 2024, there were 6,602,495 shares available for grant. The following tables summarize stock option activity under the Stock Plans for the year ended December 31, 2024: Outstanding Options Weighted Average Exercise Price Weighted Average Remaining Contractual Life (in years) Aggregate intrinsic value (in thousands) Balance as of December 31, 2023 5,478,010 $ 0.17 6.05 Exercised (1,074,085) 0.22 Forfeited / canceled (445,518) 0.14 Expired (40,433) 0.17 Balance as of December 31, 2024 3,917,974 $ 0.17 5.52 Vested and expected to vest at December 31, 2024 3,917,974 $ 0.17 5.52 $ 4,36 8 Vested and exercisable at December 31, 2024 2,837,690 $ 0.17 5.40 $ 3,13 6

80 The total intrinsic value of the options exercised for the years ended December 31, 2024 and 2023 was $0.5 million and $2.5 million, respectively. The intrinsic value of options exercised during each fiscal year is calculated as the difference between the market value of the stock at the time of exercise and the exercise price of the stock option. As of December 31, 2024, the Company had stock-based compensation of $0.1 million, related to unvested stock options not yet recognized that is expected to be recognized over an estimated weighted average period of 1.6 years. The following table summarizes the RSU activity for the year ended December 31, 2024: Outstanding Weighted- average grant date fair value Unvested balance at December 31, 2023 10,927,261 $ 1.94 Granted - RSU awards 8,464,852 0.96 RSU awards vested and converted to shares (3,293,611) 2.26 Forfeited - RSU awards (1,958,692) 2.06 Unvested balance December 31, 2024 14,139,810 $ 1.23 The RSU awards entitle the holder upon vesting to be issued on a future date the number of shares of Common Stock that is equal to the number of restricted stock units subject to the RSU awards. The total fair value of shares vested for the years ended December 31, 2024 and 2023 was $4.6 million and $2.7 million, respectively. The number of RSU awards vested during 2024 and 2023 was 3,994,567 and 1,919,853, respectively, of which the issuance of 294,142 and 165,956 common shares has been deferred at the election of the participant during 2024 and 2023, respectively. The common shares for the deferred RSUs will be released sixty days following the participant's departure from the Company. The common shares for an additional 406,814 RSU awards vested

81 during 2024 will be issued in 2025. The common shares for an additional 40,734 RSU awards vested during 2023 and issued in 2024. The vesting period for RSU awards is generally three years. Total remaining compensation expense for RSU awards to be recognized under the 2021 Equity Incentive Plan is $14.9 million as of December 31, 2024, which is expected to be recognized over an estimated weighted average period of 1.5 years. The following table summarizes the PSU award activity for the year ended December 31, 2024: Outstanding Weighted- average grant date fair value Unvested balance at December 31, 2023 2,118,843 $ 5.77 Forfeited - PSU awards (528,616) 7.02 Unvested balance December 31, 2024 1,590,227 $ 5.33 The Company issued 455,368 PSU awards during 2023. For the year ended December 31, 2024, the performance conditions for the PSU awards granted in 2023 was met, therefore PSU award stock-based compensation expenses of $0.1 million was recorded. For the year ended December 31, 2023, the performance conditions for all of the outstanding PSU awards were not probable of being met, therefore no PSU stock-based compensation expenses were recorded. As of December 31, 2024, there were 1,490,818 unvested PSU awards subject to certain performance criteria for vesting. The maximum amount of stock-based compensation expenses for the unvested PSU awards, assuming maximum performance, is $7.9 million. Total remaining compensation expenses for PSU awards will be recognized over the requisite service periods once the performance-based conditions are met or deemed to be probable. As discussed in Note 2, the Company effected workforce reductions in September 2024 and November 2023. The Board authorized certain changes to the stock-based awards in connection with the workforce reduction plan to allow accelerated vesting of a portion of affected employees’ unvested stock-based awards. The Company recorded a total workforce reduction charge of $0.6 million and $0.2 million in the years ended December 31, 2024 and 2023, respectively. The charge consists of severance and benefits costs, inclusive of cash expenditures for employee separation costs of $0.5 million in each of the years ended December 31, 2024 and 2023 and non- cash stock-based compensation expenses of $0.1 million and $(0.3) million, respectively. The cash expenditures and non-cash stock based compensation expense for employee separation costs were recorded in general and administrative and research and development expenses for the years ended December 31, 2024 and 2023 on the consolidated statements of operations and comprehensive (loss) income and a portion of 2023 charges were capitalized within construction in progress on the consolidated balance sheets.

82 For the years ended December 31, 2024 and 2023, stock-based compensation expenses of $7.7 million and $6.5 million, respectively, was recognized in general and administrative expenses in the consolidated statements of operations and comprehensive (loss) income, and stock-based compensation expense of $2.4 million and $2.9 million, respectively, was recognized in research and development expenses in the consolidated statements of operations and comprehensive (loss) income. 13. Segment Reporting Operating segments are identified as components of an enterprise for which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) for purposes of making decisions regarding resource allocation and evaluating financial performance. As of the year ended December 31, 2024, the Company has determined that its Chief Executive Officer and Chief Financial Officer/Chief Operating Officer are the CODMs. The CODMs review the consolidated results of operations when making decisions about allocating resources and assessing the performance of the Company as a whole as the Company is still in an early stage of business. The Company does not distinguish between markets or segments for the purpose of internal reporting. Accordingly, the Company has determined that it operates in a single operating and single reportable segment at the consolidated entity level. The CODMs uses net (loss) income and loss from operations as the key performance measures to make key operating decisions. Revenues are based on the location where services are provided and products are sold. All of the Company’s revenues are attributable to the U.S. for the periods presented. Reported segment net (loss) income and loss from operations for the Company’s single reportable segment are shown in the consolidated statements of operations and comprehensive (loss) income. The following table presents the significant segment expenses that are regularly provided to the CODMs: (in thousands) December 31, 2024 December 31, 2023 Operating expenses: Personnel Expense $ 22,274 $ 19,871 Other Expense 63,007 40,225 Total operating expenses $ 85,281 $ 60,096 The personnel expense represents payroll expenses excluding stock-based compensation. The other expense represents research and development excluding personnel expense, general and administrative excluding personnel expense, depreciation and amortization expense, and impairment of assets.

84 The federal, state, and foreign income and deferred tax (provision) benefit are summarized as follows for the years ended: (in thousands) December 31, 2024 December 31, 2023 Current Federal $ — $ — State (29) (20) Foreign — (139) Total current tax (provision) benefit (29) (159) Deferred Federal — — State — — Foreign (640) 1,246 Total deferred tax (provision) benefit (640) 1,246 Total income tax (provision) benefit $ (669) $ 1,087 Deferred income taxes reflect the net tax effects of temporary differences between the carrying amounts of assets and liabilities for financial reporting purposes and the amounts used for income tax purposes, and operating losses and tax credit carryforwards.

85 The tax effects of significant items comprising the Company’s deferred taxes are as follows as of: (in thousands) December 31, 2024 December 31, 2023 Deferred tax assets Net operating loss carryforwards $ 45,734 $ 34,076 Available for sale marketable securities 288 825 Lease liabilities 945 1,050 Other 263 51 Fixed assets and intangibles — 445 Capitalized research and development costs 7,715 4,456 Stock Compensation 1,636 2,806 Total deferred tax assets 56,581 43,709 Valuation allowance (53,775) (41,420) Deferred tax liabilities ROU asset (835) (1,012) Other — (16) Fixed assets and intangibles (1,350) — Total deferred tax liabilities (2,185) (1,028) Net deferred tax assets $ 621 $ 1,261 ASC 740 requires that the tax benefit of net operating losses, temporary differences and credit carryforwards be recorded as an asset to the extent that management assesses that realization is more likely than not. Realization of the future tax benefits is dependent on the Company’s ability to generate sufficient taxable income within the carryforward period. Regarding the Origin US entities, the Company is in a significant cumulative loss position and has provided a valuation allowance against the US net deferred tax assets. Origin Canada is recognizing income and is projecting future taxable income sufficient to offset all its deferred tax assets. Therefore, some of the deferred tax assets in Canada are being recognized in 2023. The valuation allowance increased by $12.4 million and $9.1 million for the years ended December 31, 2024 and 2023, respectively.

86 At December 31, 2024, we had federal net operating loss carryforwards of approximately $159.8 million to offset future federal taxable income, with $44.9 million available through 2037. We have state net operating loss carryforward of $100.6 million, available through 2044. The Company plans to evaluate its R&D credits in the future and amend prior year federal an California tax returns to claim credits, which will carryforward to offset future income tax liability. The effective tax rate of the Company’s income tax (provision) benefit differs from the federal statutory rate as follows for the years ended: December 31, 2024 December 31, 2023 (in thousands, except percentages) Amount Percent Amount Percent Statutory rate $ 17,436 (21.0) % $ (4,769) (21.0) % State tax (1,764) 2.1 % 2,761 12.2 % Foreign tax — — % (139) (0.6) % Valuation allowance (12,843) 15.5 % (10,629) (46.8) % Other (321) 0.4 % (98) (0.5) % Warrants and other equity items (825) 1.0 % 14,808 65.3 % Foreign rate differential (78) 0.1 % (128) (0.6) % Stock-based compensation (2,274) 2.7 % (719) (3.2) % Total $ (669) 0.8 % $ 1,087 4.8 % Under certain provisions of the Internal Revenue Code of 1986, as amended, a portion of the federal and state net operating loss carryforwards may be subject to an annual utilization limitation as a result of a change in ownership of the Company. Federal and California tax laws impose significant restrictions on the utilization of net operating loss carryforwards in the event of a change in ownership of the Company, as defined by Internal Revenue Code Section 382 (“Section 382”). The Company has experienced ownership changes as defined by IRC Section 382 and the impact of those changes has been reflected in the consolidated financial statements. In addition, in the future the Company may experience ownership changes, which may limit the utilization of net operating loss carryforwards or other tax attributes. There were no unrecognized tax benefits in the years ended December 31, 2024 and 2023. The Company files income tax returns in the United States, various US states, and Canada. All tax years remain open in all jurisdictions. The Company is not currently under examination by income tax authorities in federal, state or other foreign jurisdictions. The Company does not anticipate any significant changes within 12 months of this reporting date of its uncertain tax positions.

During the third and fourth quarters of 2024, the Company entered into multiple purchase agreements with various vendors to purchase equipment to fulfill a near-term demand for our PET closures. Pursuant to the agreements, the Company committed to purchase the equipment with installment payments. The Company made payments totaling of $6.3 million as of December 31, 2024 and recorded the amount in property, plant, and equipment, net on the consolidated balance sheets. The Company is obligated to make additional payments toward the remaining balances of up to approximately $7.3 million subject to the achievement of certain milestones.

89 In April 2023, the Company entered into an agreement for conversion of materials produced by Origin 1 into certain derivatives. Pursuant to the agreement, the Company agreed to purchase conversion services for a certain minimum quantity of product on a take-or-pay basis for a term of 5 years beginning in 2025 for an aggregate total cost of $33.0 million. Accordingly, the Company is obligated to purchase not less than $5.0 million during 2025 and a minimum of $7.0 million each of 2026 through 2029.

The agreement automatically renews for an additional year unless either party gives advance notice of an intention not to renew. In addition, either party may terminate the agreement in the event of the other party’s insolvency or breach of a material term. The Company recorded the advance payments of $16.6 million and $11.5 million as of December 31, 2024 and 2023, respectively, in other long-term assets on the consolidated balance sheets. In February 2023, the Company entered into a nonexclusive patent license agreement for use in connection with production at a specific licensed facility. The license expires upon cessation of production at that facility. The Company made a nonrefundable $5.0 million deposit in 2022 toward securing the license and, as a result of signing the license agreement, made an additional nonrefundable payment of $7.9 million during 2023 and may make additional payments depending on the achievement of certain milestones. The total payment of $12.9 million is included in other long-term assets on the consolidated balance sheets as of December 31, 2024 and 2023. The Company also entered into a conditional offtake agreement under which, subject to certain conditions being met, the licensor was to supply the Company with a certain amount of the same type of products to be produced at the licensed facility in order to accelerate market development for these products and related applications. The Company gave notice of termination of the conditional offtake agreement in January 2025. In July 2017, the Company entered into a nonexclusive patent license agreement for $0.1 million, which expires upon expiration of the last to expire of the licensed patents. Under this agreement, the Company will pay less than $0.1 million minimum royalty payments per year and, if the Company develops and sells certain products based on the licensed patents. Certain products that Origin is currently developing and anticipates selling are expected to utilize these patents. In December 2016, the Company entered into a patent license agreement for $0.5 million, which expires upon expiration of the last to expire of the licensed patents. Under this agreement, if the Company manufactures specific products at Origin 1 based on the patents and sells those products, the Company would pay a royalty up to a cumulative $0.5 million. Thereafter, no further payments will be due for any production at Origin 1. If production of products based on the licensed patents occurs at other facilities, the Company will pay an upfront license fee royalty and a variable royalty based on production at that subsequent facility, capped at an aggregate $10.0 million per such facility. Certain products that the Company is currently developing, if sold, are expected to utilize these patents. The company does not currently anticipate such sales. No payments have been made under this agreement through December 31, 2024. In November 2016, the Company entered into a nonexclusive patent license agreement, which expires upon expiration of the patent. Under this agreement, if the Company produces products based on the patent, the Company will pay an annual royalty upon commencement of operations on Origin 1 which will not exceed $1.0 million cumulatively. The pipeline of Company products and sales are not currently expected to be subject to this patent. The annual royalty payments are less than $0.1 million. The Company terminated the license effective April 26, 2024.

90 In September 2011, the Company entered into a nonexclusive patent license agreement, which expires upon expiration of the patent. Under this agreement, if the Company develops and sells specific products based on the patent, the Company would pay a royalty up to $2.0 million per year and $10.0 million in the aggregate. Certain products that the Company is currently developing, if sold, are expected to utilize these patents. The company does not currently anticipate such sales. There were $0.1 million and no payments made for the years ended December 31, 2024 and 2023, respectively. In June 2011, the Company entered into a nonexclusive patent license agreement, which expires upon expiration of the licensed patent. Under this agreement, the Company pays less than $0.1 million royalty fee annually and if the Company develops and sells specific products based on the patent, 0.4% of net sales. The pipeline of Company products and sales are not currently expected to be subject to this patent. We enter into supply and service arrangements in the normal course of business. Supply arrangements are primarily for fixed-price manufacture and supply. Service agreements are primarily for the development of manufacturing processes and certain studies. Commitments under service agreements are subject to cancellation at our discretion which may require payment of certain cancellation fees. The timing of completion of service arrangements is subject to variability in estimates of the time required to complete the work. Contingencies At times there may be claims and legal proceedings generally incidental to the normal course of business that are pending or threatened against the Company. Since August 2023, the Company has been litigating a putative securities class action in the Eastern District of California against the Company and certain of its officers alleging violations of the federal securities laws in connection with the Company's announcement on August 9, 2023, that it expected the timeline for construction of its Origin 2 project to be delayed (In re Origin Materials, Inc. Sec. Litig., No. 2:23-cv-01816-WBS-JDP (E.D. Cal.)). The Court has appointed a lead plaintiff. The Court has ruled twice on motions to dismiss the Complaint, most recently granting it in part and denying it in part. At this preliminary stage in the litigation, the Company cannot predict any particular outcome or financial impact thereof, if any. In March 2025, two shareholders each filed a derivative complaint in the Eastern District of California against certain of the Company’s current and former directors, with the Company as a nominal defendant. The cases are Thomas Kaspar v. John Bissell, et al., Case No. 2:25-at-00326 (E.D. Cal. Mar. 7, 2025) and Travis Tanasse v. John Bissell, et al., Case No. 2:25-at-00331 (E.D. Cal. Mar. 10, 2025). The complaints allege breaches of fiduciary duty and related state and federal claims in connection with the same August 9, 2023 announcement by the Company that is at issue in the In re Origin Materials, Inc. Sec. Litig. case. As relief, purportedly on behalf of the Company, each plaintiff seeks unspecified damages, fees and costs, and governance changes. At this preliminary stage in the litigation, the Company cannot predict any particular outcome or financial impact thereof, if any.

91 17. Basic and Diluted Net (Loss) Income Per Share The following table sets forth the computation of basic and diluted net (loss) income per share attributable to common stockholders. Basic net (loss) income per share is computed by dividing net (loss) income for the period by the weighted-average number of common shares outstanding during the period, which excludes Sponsor Vesting Shares which are legally outstanding, but subject to return to the Company. Diluted net (loss) income per share is computed by dividing net (loss) income for the period by the weighted-average common shares outstanding during the period, plus the dilutive effect of the stock options and RSU awards, as applicable pursuant to the treasury stock method. The following table sets forth the computation of basic and diluted net (loss) income per share: (In thousands, except for share and per share amounts) December 31, 2024 December 31, 2023 Numerator: Net (loss) income attributable to common stockholders—Basic $ (83,697) $ 23,798 Net (loss) income attributable to common stockholders—Diluted $ (83,697) $ 23,798 Denominator: Weighted-average common shares outstanding—Basic (1) 143,192,630 139,718,385 Stock options — 2,872,491 RSU awards — 67,547 Weighted-average common shares outstanding—Diluted (1) 143,192,630 142,658,423 Net (loss) income per share—Basic $ (0.58) $ 0.17 Net (loss) income per share—Diluted $ (0.58) $ 0.17 (1) Excludes weighted-average Sponsor Vesting Shares subject to return of 3,727,397 and 4,500,000 shares for the years ended December 31, 2024 and 2023, respectively.

92 Diluted net (loss) income per share reflects the potential dilution of securities that could dilute share in the earnings of an entity. The following potentially dilutive securities for common stock were outstanding and excluded from diluted net (loss) income per share as they are subject to performance or market conditions that were not achieved as follows: December 31, 2024 December 31, 2023 Options to purchase common stock 1,058,231 1,481,531 PSU awards 1,590,227 2,018,934 Earnout shares 25,000,000 25,000,000 Sponsor vesting shares 3,000,000 4,500,000 The following outstanding shares of out-of-the-money options and potentially dilutive securities were excluded from the computation of diluted net (loss) income per share attributable to common stockholders for the periods presented because including them would have been antidilutive: December 31, 2024 December 31, 2023 Options to purchase common stock 2,859,743 41,357 Warrants to purchase common stock 35,476,627 35,476,627 RSU awards 14,139,810 — Item 9. Changes in and Disagreements with Accountants on Accounting and Financial Disclosures None. Item 9A. Controls and Procedures Limitations on Effectiveness of Controls and Procedures In designing and evaluating our “disclosure controls and procedures,” as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), and “internal controls over financial reporting,” as such term is defined in Rule 13a-15(f) under the Exchange Act, our management, including our Chief Executive Officer and Chief Financial Officer, believe that our disclosure controls and procedures and our internal control over financial reporting are designed to provide reasonable assurance of achieving their objectives and are effective at the reasonable assurance level. Our management does not expect that our disclosure controls and procedures or our internal control over financial reporting will prevent

93 all errors and all instances of fraud. A control system, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the control system are met. Further, the design of a control system must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all control systems, no evaluation of controls can provide absolute assurance that all control deficiencies and instances of fraud, if any, have been detected. The design of any system of controls also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. Evaluation of Disclosure Controls and Procedures Our management, under the direction of our Chief Executive Officer and Chief Financial Officer, has evaluated the effectiveness of the design and operation of our disclosure controls and procedures as of the period covered by this Annual Report on Form 10-K. Based on this evaluation, our management, including our Chief Executive Officer and Chief Financial Officer, has concluded that, as of December 31, 2024, our disclosure controls and procedures were effective at the reasonable assurance level. Management’s Annual Report on Internal Control Over Financial Reporting Our management is responsible for establishing and maintaining adequate internal control over financial reporting. Our management, under the supervision and with the participation of our Chief Executive Officer and Chief Financial Officer, conducted an evaluation of the effectiveness of our internal control over financial reporting as of December 31, 2024. In making this evaluation, our management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission in Internal Control—Integrated Framework (2013). Based upon the results of its evaluation, our management concluded that, as of December 31, 2024, our internal control over financial reporting was effective. This annual report does not include an attestation report of the Company’s registered public accounting firm regarding internal control over financial reporting. The Company’s internal control over financial reporting was not subject to attestation by the Company’s registered public accounting firm as we are a non-accelerated filer. Our management will continue to monitor and evaluate the effectiveness of its disclosure controls and procedures, as well as its internal control over financial reporting, on an ongoing basis, and is committed to taking further action and implementing additional improvements, as necessary and as funds allow. Our management believes that there are no material inaccuracies or omissions of material fact and, to the best of its knowledge, believes that the consolidated financial statements included in this annual report present fairly, in all material respects, our financial position, results of operations, and cash flows for the periods presented in conformity with accounting principles generally accepted in the United States. Changes in Internal Control Over Financial Reporting There has been no change in our internal control over financial reporting (as defined in Rules 13a-15(f) and 15d- 15(f) under the Exchange Act) during the fourth quarter of the fiscal year ended December 31, 2024 that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
