FORWARD-LOOKING STATEMENTS

This presentation and the accompanying oral presentation have been prepared by Origin Materials, Inc. ("Origin") for informational purposes only and not for any other purpose. Certain statements included in this presentation that are not historical facts are forward-looking statements for purposes of the safe harbor provisions under the United States Private Securities Litigation Reform Act of 1995. Forward-looking statements generally are accompanied by words such as "believe," "may," "will," "estimate," "continue," "anticipate," "intend," "expect," "should," "would," "plan," "predict," "potential," "seem," "seek," "future," "outlook," and similar expressions that predict or indicate future events or trends or that are not statements of historical matters. These forward-looking statements include, but are not limited to, statements regarding Origin's business strategy, estimated total addressable market, access to traditional financing sources, budget and timelines to complete Origin 1 and Origin 2, commercial and operating plans, product development plans, anticipated growth and projected financial information. These statements are based on various assumptions, whether or not identified in this presentation, and on the current plans, objectives, estimates, expectations and intentions of the management of Origin and are not predictions of actual performance and inherently involve significant risks and uncertainties. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on as, a guarantee, an assurance, a prediction, or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Origin. These forward-looking statements are subject to a number of risks and uncertainties, including that Origin may be unable to successfully commercialize its products; the effects of competition on Origin's business; the uncertainty of the projected financial information with respect to Origin; disruptions and other impacts to Origin's business as a result of the COVID-19 pandemic and other global health or economic crises; changes in customer demand; and those factors discussed under the heading "Risk Factors," in the Quarterly Report on Form 10-Q for the quarter ended September 30, 2021. These filings, when available, are available on the investor relations section of our website at investors.originmaterials.com and on the SEC's website at www.sec.gov. If any of these risks materialize or our assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks of which Origin does not presently know, or that Origin currently believes are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Origin's expectations, plans, or forecasts of future events and views as of the date of this presentation. Origin anticipates that subsequent events and developments will cause its assessments to change. However, while Origin may elect to update these forward-looking statements at some point in the future, Origin specifically disclaims any obligation to do so except as required under applicable law. These forward-looking statements should not be relied upon as representing Origin's assessments of any date subsequent to the date of this presentation. Accordingly, undue reliance should not be placed upon the forward-looking statements.

It should not be relied upon as being indicative of future results. The assumptions and estimates underlying such projected financial information are inherently uncertain and are subject to many significant business, economic, competitive and other risks and uncertainties. Refer to "Forward-Looking Statements" above. Actual results may differ materially from the results presented in such projected financial information, and the inclusion of such information in this presentation should not be regarded as a representation by any person that the results reflected in such projections will be achieved.
