Canadian Government Research and Development Program Liability	3 Months Ended
	Mar. 31, 2026
Research and Development [Abstract]
Canadian Government Research and Development Program Liability	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 received funding for eligible expenditures incurred through March 31, 2023 up to the lesser of approximately 18.5% 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 repayment ceiling formula. In October 2025, the Company entered into an amendment for the R&D Agreement (the “R&D Agreement Amendment”). Pursuant to the R&D Agreement Amendment, the first annual repayment amount will be due on April 30, 2027, with subsequent annual repayment amounts due on or before April 30th of each year through 2041, or until such time as the maximum amount to be repaid is reached, whichever comes first. The annual repayment amounts will be determined using a formula that considers the repayment rate and changes of the fiscal year gross business revenue, as defined in the R&D Agreement Amendment. The Company received the remaining payment related to the eligible expenditures incurred before March 31, 2023 in 2025 and does not expect any subsequent payment.

Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (“Topic 326”) – Measurement of Credit Losses for Accounts Receivable and Contract Assets, to provide a practical expedient for all entities to address the challenges encountered when applying the guidance in Topic 326, Financial Instruments – Credit losses, to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606, Revenue from Contracts with Customers. All entities may elect a practical expedient that assumes the current conditions as of the balance sheet date do not change the remaining life of the asset to reduce the complexity in developing the reasonable and supportable forecasts as part of estimating expected credit losses. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, and early adoption is permitted. The Company adopted the new standard as of September 30, 2025. The adoption of the standard had no material impact on its unaudited condensed consolidated financial statements. 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 standard became effective on January 1, 2025 and will be effective for the Company for annual periods beginning after December 15, 2024. Accordingly, the standard was adopted on a prospective basis for the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The adoption of the standard did not have any material impact on the Company’s financial position, results of operations or cash flows, other than additional disclosures, which were included in the Company's annual consolidated financial statements for the year ending December 31, 2025. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual 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 unaudited condensed consolidated financial statements and disclosures. 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 within annual 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 unaudited condensed consolidated financial statements, other than additional disclosures in the notes to the unaudited condensed consolidated financial statements. The Company has determined that all other recently issued accounting pronouncements will not have a material impact on the Company’s unaudited condensed consolidated financial statements or do not apply to its operations.

Common Stock Warrants	Mar. 31, 2026
Assumed Common Stock Warrants [Abstract]
Common Stock Warrants	Common Stock Warrants As of March 31, 2026 and December 31, 2025 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 1/30th of one share of common stock at a price of $11.50 per share, subject to adjustments. The Public warrant holders will need to exercise 30 warrants for an aggregate exercise price of $345.00 to receive one share of common stock. No fractional shares will be issued upon the 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 Capital Market 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 $540.00 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 holders will need to exercise 30 warrants for an aggregate exercise price of $345.00 to receive one share of common stock. No fractional shares will be issued upon the exercise of the Private Placement Warrants. 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 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 $360.00 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 $300.00 and is less than $540.00 (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 unaudited condensed consolidated balance sheets. The fair value of the Common Stock Warrants was remeasured at each reporting period (see Note 5 for additional details), and a gain of $0.1 million and $2.8 million during the three months ended March 31, 2026 and 2025, respectively, was recorded on the unaudited condensed consolidated statements of operations and comprehensive loss.

Fair Value Disclosures [Abstract]

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 March 31, 2026
(in thousands)	Level 1		Level 2		Level 3		Total
Assets:
Cash equivalents	$	3,993	$	—	$	—	$	3,993

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 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 period. 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). Zero and a gain of $2.5 million during the three months ended March 31, 2026 and 2025, respectively, was recorded on the unaudited condensed consolidated statements of operations and comprehensive loss in the gain in fair value of earnout liability.

The value of the convertible notes, net of issuance costs is classified as a Level 3 measurements under the fair value hierarchy, as these liabilities have been valued based on significant inputs that are both observable and unobservable in the market. The Company utilized the Black-Scholes Merton model to estimate the fair value of the convertible notes. The key inputs and assumptions used in the Black-Scholes Merton model, including volatility and risk-free rate, were utilized to estimate the fair value of the associated liability (see Note 8 for additional details).

The following table summarizes the activities for the earnout liability during the three months ended March 31, 2026 and 2025:


	Three Months Ended March 31,
(in thousands)		2026		2025
Balance at beginning of period		$	24	$	2,486
Gain in fair value of earnout liability		—		(2,462)

Balance at end of period		$	24	$	24

As of March 31, 2026 and December 31, 2025, the carrying values of accounts receivable, other receivables, accounts payable, and accrued expenses approximate their respective fair values due to their short-term nature. The Company has 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.

Nonrecurring Fair Value Measurements

The Company estimates the value of certain long-lived assets associated with suspension of the furanics platform development and land held of sale using Level 3 measurements under the fair value hierarchy due to the absence of observable market prices and significant reliance on management judgment and estimation techniques. These assets include:

•Assets meeting the held for sale classification that are actively being marketed for sale. We utilized an estimated fair market based on a portion of the land sold previously, including costs to sell, as there were no observable market prices available. We expect to complete the sale of land in fiscal year 2026.

•Origin 1 plant which included property, plant, and equipment, net, that do not meet the held for sale classification but are capable of being sold through alternate use purposes. These assets were evaluated for recoverability and the impairment loss was measured using an orderly liquidation valuation approach. The impairment loss was recognized as the difference between the estimated liquidation value and the net book value of the assets as of March 31, 2026 and December 31, 2025. There have been no significant changes in the estimated net realizable value for the remaining assets as of March 31, 2026 and December 31, 2025.

The table below presents the nonrecurring fair value measurements of these long-lived assets, categorized within the fair value hierarchy:


	Fair Value as of March 31, 2026
(in thousands)	Level 1		Level 2		Level 3		Total
Assets:

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 March 31, 2026
(in thousands)	Amortized Cost		Unrealized Gains		Unrealized Losses		Fair Value

Corporate bonds	$	2,584	$	9	$	(1)	$	2,592

Total marketable securities	$	21,109	$	19	$	(583)	$	20,545

The realized gains and losses are included in other income (expenses), net in the unaudited condensed consolidated statements of operations and comprehensive loss.

The Company sold marketable securities for proceeds of $132.8 million and $282.4 million during the three months ended March 31, 2026 and 2025, respectively. As a result of those sales, the Company realized a gain of $0.1 million and a loss of $0.1 million during the three months ended March 31, 2026 and 2025, respectively. The Company regularly reviews its available-for-sale marketable securities in an unrealized loss position and evaluates 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 $10.5 million and $10.8 million as of March 31, 2026 and December 31, 2025, 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, the Company has 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 March 31, 2026
(in thousands)	Mature within one year		Mature after one year through two years		Mature over two years		Fair Value

Corporate bonds	$	1,195	$	1,397	$	—	$	2,592

Derivative Assets 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). The Company recognized zero and a net loss of less than $0.1 million during the three months ended March 31, 2026 and 2025, on the fair value adjustment of the foreign currency derivative contracts. The notional amount of foreign currency derivative contracts as of March 31, 2026 and December 31, 2025 was zero.

Earnings Per Share [Abstract]

Basic and Diluted Net Loss Per Share

The following table sets forth the computation of basic and diluted net loss per share attributable to common stockholders. Basic net loss per share is computed by dividing net loss 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 per share is computed by dividing net loss 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 per share:


(In thousands, except for share and per share amounts)	Three Months Ended March 31,
		2026		2025
Numerator:
Net loss attributable to common stockholders—Basic		$	(17,650)	$	(26,441)
Net loss attributable to common stockholders—Diluted		$	(17,650)	$	(26,441)
Denominator:
Weighted-average common shares outstanding—Basic (1)		5,377,854		4,895,078


Weighted-average common shares outstanding—Diluted (1)		5,377,854		4,895,078

Net loss per share—Basic		$	(3.28)	$	(5.40)
Net loss per share—Diluted		$	(3.28)	$	(5.40)

(1)Excludes weighted-average Sponsor Vesting Shares subject to return of 50,000 and 100,000 shares for each of the three months ended March 31, 2026 and 2025, respectively.

Diluted net loss 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 per share as they are subject to performance or market conditions that were not achieved as follows:


	Three Months Ended March 31,
		2026	2025
Options to purchase common stock		35,274	35,274
Performance-based stock awards		33,750	70,808
Earnout shares		833,333	833,333
Sponsor Vesting Shares		50,000	100,000

The following outstanding shares of potentially dilutive securities were excluded from the computation of diluted net loss per share attributable to common stockholders for the periods presented because including them would have been antidilutive:


	Three Months Ended March 31,
		2026	2025
Options to purchase common stock		192,955	95,218
Warrants to purchase common stock		1,182,554	1,182,554

Summary of Significant Accounting Policies (Policies)	Mar. 31, 2026
Accounting Policies [Abstract]
Basis of Presentation	Basis of Presentation The Company’s unaudited condensed 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	Use of Estimates The preparation of the unaudited condensed 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 convertible debt, 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 unit (“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.
Unaudited Condensed Consolidated Financial Statements	Unaudited Condensed Consolidated Financial Statements The December 31, 2025 unaudited condensed consolidated balance sheet was derived from the annual audited consolidated financial statements included in the Company's Form 10-K as filed with the SEC on March 27, 2026 (the “Form 10-K”). The accompanying unaudited condensed consolidated balance sheet as of March 31, 2026, the unaudited condensed consolidated statements of operations and comprehensive loss, and stockholders’ equity for the three months ended March 31, 2026 and 2025, the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2026 and 2025, and the notes to such unaudited condensed consolidated financial statements are unaudited. These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and the applicable rules and regulations of the SEC for interim financial information. As permitted under those rules, we condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements. The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in management’s opinion, include all adjustments consisting of only normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of March 31, 2026 and its results of operations for the three months ended March 31, 2026 and 2025 and cash flows for the three months ended March 31, 2026 and 2025. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full fiscal year or any other period. These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited annual financial statements and notes thereto for the year ended December 31, 2025 included in the Form 10-K.
Principles of Consolidation	Principles of Consolidation The unaudited condensed 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	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 the Company’s ability to access our cash and cash equivalents. If the Company is unable to access its cash and cash equivalents as needed, its financial position and ability to operate its business could be adversely affected. The Company’s marketable securities consist 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 unaudited condensed consolidated statements of operations and comprehensive loss, up to the amount of total outstanding accounts receivable to date.
Held for Sale Classification	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 within 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 their 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 unaudited condensed consolidated balance sheets.
Impairment of Long-Lived Assets	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. The decision was made to indefinitely suspend all further furanics platform development and plant operations for Origin 1. As a result, during the year ended December 31, 2025, the Company determined that indicators of impairment existed for the Origin 1 asset group. We evaluated the fair value of the Origin 1 asset group under an orderly liquidation approach as the primary valuation methodology, with corroborative consideration given to an alternative use undiscounted cash flow and eventual disposition approach. The fair value of the Origin 1 asset group was approximated at $18.0 million. As such, the Company recorded an impairment charge of $134.5 million. The Company determined that indicators of impairment existed for Origin 2 asset group, as well, with the decision to indefinitely suspend the furanics platform development. The Company concluded the carrying costs of the labor, benefits and external engineering fees that had been capitalized to construction in progress for the Origin 2 asset group were no longer recoverable. As such, the Company recorded an impairment charge of $31.4 million to impairment of assets on the unaudited condensed consolidated statements of operations and comprehensive loss for the year ended December 31, 2025. In addition, the Company had entered into a nonexclusive patent license agreement for use in connection with the production of Origin 2 and made nonrefundable payments totaling $12.9 million in prior years towards securing a license. The Company believes that the payments made towards the license agreement are no longer recoverable and recorded an impairment charge of $12.9 million to impairment of assets on the unaudited condensed consolidated statements of operations and comprehensive loss for the years ended December 31, 2025.
Common Stock Warrants Liability	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 common stock at an exercise price of at $11.50 per share; however, warrant holders will need to exercise 30 warrants for an aggregate exercise price of $345.00 to receive one share of common stock. No fractional shares will be issued upon the exercise of the warrants. As of March 31, 2026, 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 March 31, 2026. 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 50.0% or more of the Company’s 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 unaudited condensed consolidated balance sheets at fair value, with subsequent changes in their respective fair values recognized in the gain in fair value of common stock warrants liability within the unaudited condensed consolidated statements of operations and comprehensive loss 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.
Revenue Recognition	Revenue Recognition The Company’s revenues are from product sales and service agreements. The majority of the Company’s contracts with customers typically contain multiple products and services. The Company accounts 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 services 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 the Company fulfills its obligations under its product revenue and service agreements, the Company performs 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. The Company accounts 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 the Company’s order confirmation, in exchange for future consideration, create enforceable rights and obligations on both parties and constitute a contract with a customer. The Company’s 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. The Company identifies each performance obligation at contract inception and allocates the consideration to each distinct performance obligation based on the stand-alone selling price of each performance obligation. The Company’s services are tailored to each individual customer and the stand-alone selling prices are not directly observable. Because the Company’s service agreements include customers that are not in similar geographic markets and for different services, the Company uses the expected cost plus margin approach to estimate the stand-alone selling price for each of its performance obligations. The Company recognizes revenue from the service agreements over the period during which the services are performed and recognizes the associated costs as they are incurred. In general, the Company recognizes revenue when, or as, its performance obligations under the terms of a contract with its customer are satisfied. For product sales, this happens when the Company transfers control of its products and risk of loss to the customer or when title passes upon shipment. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring its 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 the Company expects to be entitled to in exchange for those goods or services. The Company has elected to treat shipping and handling activities as fulfillment costs.
Basic and Diluted Net Loss Per Share	Basic and Diluted Net Loss Per Share Basic net loss per common share is calculated by dividing the net loss 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 per share is computed by dividing the net loss 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 per share calculation, common stock options, restricted stock unit (“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.
Recent Accounting Pronouncements	Recent Accounting Pronouncements In July 2025, the FASB issued ASU 2025-05, Financial Instruments – Credit Losses (“Topic 326”) – Measurement of Credit Losses for Accounts Receivable and Contract Assets, to provide a practical expedient for all entities to address the challenges encountered when applying the guidance in Topic 326, Financial Instruments – Credit losses, to current accounts receivable and current contract assets arising from transactions accounted for under Topic 606, Revenue from Contracts with Customers. All entities may elect a practical expedient that assumes the current conditions as of the balance sheet date do not change the remaining life of the asset to reduce the complexity in developing the reasonable and supportable forecasts as part of estimating expected credit losses. ASU 2025-05 is effective for annual reporting periods beginning after December 15, 2025, and interim reporting periods within those annual reporting periods, and early adoption is permitted. The Company adopted the new standard as of September 30, 2025. The adoption of the standard had no material impact on its unaudited condensed consolidated financial statements. 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 standard became effective on January 1, 2025 and will be effective for the Company for annual periods beginning after December 15, 2024. Accordingly, the standard was adopted on a prospective basis for the Company's Annual Report on Form 10-K for the year ended December 31, 2025. The adoption of the standard did not have any material impact on the Company’s financial position, results of operations or cash flows, other than additional disclosures, which were included in the Company's annual consolidated financial statements for the year ending December 31, 2025. In December 2025, the FASB issued ASU 2025-11, Interim Reporting (Topic 270): Narrow-Scope Improvements, which is intended to improve the navigability of the guidance in ASC 270, Interim Reporting, and clarify when it applies. Under the amendments, an entity is subject to ASC 270 if it provides interim financial statements and notes in accordance with GAAP. ASU 2025-11 also addresses the form and content of such financial statements, interim disclosures requirements, and establishes a principle under which an entity must disclose events since the end of the last annual reporting period that have a material impact on the entity. ASU 2025-11 is effective for interim reporting periods within annual 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 unaudited condensed consolidated financial statements and disclosures. 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 within annual 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 unaudited condensed consolidated financial statements, other than additional disclosures in the notes to the unaudited condensed consolidated financial statements. The Company has determined that all other recently issued accounting pronouncements will not have a material impact on the Company’s unaudited condensed consolidated financial statements or do not apply to its operations.
Segment Reporting	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 quarter ended March 31, 2026, the Company has determined that its Chief Executive Officer and Chief Financial Officer/Chief Operating Officer are the CODMs. The CODMs review the unaudited condensed 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 use net loss 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 and loss from operations for the Company’s single reportable segment are shown in the unaudited condensed consolidated statements of operations and comprehensive loss.

Income Tax Disclosure [Abstract]
Income Taxes	Income Taxes The provision for income taxes is recorded at the end of each interim period based on the Company’s best estimate of its effective income tax rate expected to be applicable for the full fiscal year, adjusted for any discrete items during the quarter. The Company has recorded an income tax provision of zero and less than $0.1 million during the three months ended March 31, 2026 and 2025, respectively, related to foreign income taxes in Canada. Other than Canadian income taxes, there is no provision for income taxes because the U.S. Company has incurred operating losses since inception. The Company’s effective income tax rate was zero and (0.22)% for the three months ended March 31, 2026 and 2025, respectively. The Company continues to maintain a full valuation allowance on its net deferred tax assets in the U.S. and Canada.

- Definition

The entire disclosure for income tax.

Stockholders' Equity

3 Months Ended

Mar. 31, 2026

Stockholders' Equity Note [Abstract]

Stockholders' Equity

Stockholders’ Equity

Common Stock

Holders of the common stock are entitled to dividends when, as, and if, declared by the board of directors (the “Board”), subject to the rights of the holders of all classes of stock outstanding having priority rights to dividends. As of March 31, 2026, 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 85.0% 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 the Company’s common stock that could be issued under the ESPP was 61,557. 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 (1.0%) of the fully-diluted shares of the Company’s common stock on December 31st of the preceding calendar year, (2) 123,114 of common stock, or (3) such lesser number of shares as determined by the Board. As of December 31, 2025, the number of shares available for issuance under the ESPP was 187,998. The Board made the decision not to increase the number of shares of common stock reserved for issuance under the ESPP as of January 1, 2026 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 25.0% 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 awards are determined to be the grant date closing stock price. For awards with performance-based conditions, compensation is recorded once there is sufficient objective evidence the performance conditions are considered probable of being met. The PSU awards are subject to vesting based on a performance-based condition and a service-based condition. The PSU awards will vest in a percentage of the target number of shares between 0% and 300.0%, depending on the extent the performance conditions are achieved.

Initially, following adoption of the 2021 Equity Incentive Plan, there were 615,570 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 (5.0%) of the fully-diluted common stock on December 31 of the preceding year unless the 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 (15.0%) of the fully-diluted common stock on December 31 of the preceding year. As of December 31, 2025, the number of shares available for issuance under the 2021 Equity Incentive Plan was 1,025,078 which exceeded fifteen percent of the fully-diluted common stock on January 1, 2026, therefore the share was not automatically increased pursuant to the 2021 Equity Incentive Plan’s “evergreen” provision. As of March 31, 2026, there were 195,956 shares available for grant.

The following tables summarize stock option activity under the Stock Plans for the period ended March 31, 2026:


(In thousands, except for share and per share amounts)	Outstanding Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)
Balance as of December 31, 2025	81,827	$	4.80	4.77
Granted	157,001	4.50

Forfeited / canceled	(10,599)	4.20

Balance as of March 31, 2026	228,229	$	4.62	8.22








Vested and expected to vest at March 31, 2026	181,692	$	4.46	9.17
Vested and exercisable at March 31, 2026	181,692	$	4.46	9.17

As of March 31, 2026, the aggregate intrinsic value of the options expected to vest and exercisable were zero as the market value of the stock was less than the exercise price of the stock option. The total intrinsic value of the options exercised was zero and less than $0.1 million during the three months ended March 31, 2026 and 2025, respectively. The intrinsic value of options exercised during each reporting period 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. The total fair value of options vested during the three months ended March 31, 2026 and 2025 was zero and less than $0.1 million, respectively. As of March 31, 2026, the Company had stock-based compensation of less than $0.6 million, related to unvested stock options not yet recognized that is expected to be recognized over an estimated weighted average period of 1.1 years.

The following table summarizes the RSU award activity for the period ended March 31, 2026:


	Unvested outstanding	Weighted-average grant date fair value		Vested-deferred outstanding	Weighted-average grant date fair value		Total
Balance at December 31, 2025	281,401	$	28.20	38,824	$	28.20	320,225
Granted - RSU awards	111,410	5.67		—	—		111,410
RSU awards vested and converted to shares	(8,750)	37.19		(3,461)	37.19		(12,211)
RSU awards vested and deferred	(3,063)	37.19		3,063	37.19		—
Forfeited - RSU awards	(73,191)	24.88		—	—		(73,191)
Balance at March 31, 2026	307,807	$	20.93	38,426	$	20.93	346,233

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 was $0.1 million and $0.4 million during the three months ended March 31, 2026 and 2025, respectively. As of March 31, 2026 the unvested-deferred outstanding balance of 38,426 RSU awards has been deferred at the election of the participant. The common shares for the deferred RSUs will be released sixty days following the participant’s departure from the Company.

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 $4.4 million as of March 31, 2026, which is expected to be recognized over an estimated weighted average period of 1.2 years.

The following table summarizes the PSU award activity for the period ended March 31, 2026:


	Outstanding	Weighted-average grant date fair value
Unvested balance at December 31, 2025	41,636	$	50.40
Granted - PSU awards	12,242	4.68
PSU awards vested and converted to shares	(7,495)	26.34
Forfeited - PSU awards	(12,633)	78.29
Unvested balance at March 31, 2026	33,750	$	35.65

The performance conditions for the PSU awards granted in 2023 were met and for the PSU awards granted in 2025 were partially met, therefore PSU stock-based compensation expense of $50.8 thousand and $72.2 thousand was recorded during the three months ended March 31, 2026 and 2025, respectively. The performance conditions for the remaining outstanding PSU awards granted in 2021 were not probable of being met, therefore no PSU stock-based compensation expense was recorded for such awards during the three months ended March 31, 2026 and 2025. The maximum amount of stock-based compensation expense for the unvested PSU awards, assuming maximum performance, is $1.2 million as of March 31, 2026. Total remaining stock-based 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.

During the three months ended March 31, 2026 and 2025, stock-based compensation expense of $0.7 million and $1.8 million, respectively, was recognized in general and administrative expenses, and $0.3 million and $0.5 million, respectively, was recognized in research and development expenses on the unaudited condensed consolidated statements of operations and comprehensive loss.

Earnout Liability	3 Months Ended
Earnout Liability	Mar. 31, 2026
Earnout Liability Disclosure [Abstract]
Earnout Liability	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 833,333 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 or exceeding $450.00 for ten consecutive trading days during the three year period following the closing date of June 25, 2021, ending June 25, 2024; (b)the VWAP equaling or exceeding $600.00 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 $750.00 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 150,000 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 and second Triggering Events were not met by the respective June 25, 2024 and June 25, 2025 deadlines, and the number of Sponsor Vesting Shares valued in the Earnout Liability balance were reduced accordingly. The 50,000 shares that expired on June 25, 2025 were cancelled on July 1, 2025. The remaining 50,000 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 unaudited condensed 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%, volatility of 100%, and interest rate of 3.92% at each of March 31, 2026 and December 31, 2025.

Organization, Consolidation and Presentation of Financial Statements [Abstract]
Organization and Business	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. In September 2024, Origin’s first PET closure manufacturing system (“CapFormer”) successfully completed its Factory Acceptance Test (“FAT”), which involves a series of tests performed on the system to ensure that it meets our requirements and functions as intended. Due to absent near-term financing, the decision was made to indefinitely suspend all further furanics platform development and plant operations for Origin 1 in February 2026. Reverse Stock Split On February 17, 2026, the Company held a special meeting of stockholders at which its stockholders approved the amendment of its amended and restated certificate of incorporation to effect a reverse split of its common stock at a ratio in the range of one-for-two to one-for-fifty, such ratio to be determined in the discretion of its board of directors. On March 4, 2026, the Company's board of directors approved the filing of a certificate of amendment with the Secretary of State of the State of Delaware to effect a one-for-thirty reverse stock split of its outstanding common stock. On March 19, 2026, the Company filed the certificate of amendment with the Secretary of State of Delaware to effect the reverse split. All issued and outstanding common stock, options to purchase common stock, and per share amounts contained in the unaudited condensed consolidated financial statements have been retroactively adjusted to reflect the reverse stock split for all periods presented. The Company’s publicly traded warrants will continue to trade on the Nasdaq Capital Market under the symbol “ORGNW” with an exercise price of $11.50 per share; however, warrant holders will need to exercise 30 warrants for an aggregate exercise price of $345.00 to receive one share of common stock. No fractional shares will be issued upon the exercise of the warrants. Plan of Dissolution On April 28, 2026, the Board of Directors (the “Board”) of the Company unanimously approved the dissolution and liquidation of the Company pursuant to a plan of complete liquidation and dissolution (the “Plan of Dissolution”), subject to stockholder approval. In connection with the approval of the Plan of Dissolution, the Board also approved a reduction-in-force, which the Company implemented on May 1, 2026 to enable the Company to maximize shareholder value through the orderly sale of its technology and assets followed by dissolution and wind down. If its stockholders authorize the Plan of Dissolution, the Company plans to file a Certificate of Dissolution with the Secretary of the State of Delaware in the second quarter of 2026. Liquidity and going concern As reflected in the unaudited condensed consolidated financial statements, the Company had $32.6 million in cash, cash equivalents, and marketable securities as of March 31, 2026. The Company has experienced net losses and negative cash flows from operating activities since its inception and had an accumulated deficit of $305.5 million as of March 31, 2026. The Company has incurred a net loss and net cash used in operating activities of $17.7 million and $4.9 million, respectively, for the three months ended March 31, 2026. In accordance with Accounting Standards Codification, or ASC, 205-40, Going Concern, the Company evaluated whether there are conditions and events, considered in the aggregate, that raise substantial doubt about its ability to continue as a going concern within one year after the date that these unaudited condensed consolidated financial statements are issued on May 14, 2026. The Company has determined that its cash, cash equivalents, and marketable securities as of March 31, 2026 would be insufficient to fund its operations which raises substantial doubt regarding the Company's ability to continue as a going concern. The Company intends to implement the Plan of Dissolution which will result in the dissolution and liquidation of the Company. As the Plan of Dissolution has not yet been brought to a vote of or approved by the Company's stockholders, the Company concluded that the liquidation basis of accounting should not be applied as of the balance sheet date. Accordingly, the accompanying unaudited condensed consolidated financial statements are prepared in accordance with generally accepted accounting principles applicable to a going concern, which contemplates the realization of assets and the satisfaction of liabilities in the normal course of business. The Company’s unaudited condensed consolidated financial statements have been prepared assuming that the Company will continue as a going concern and do not include any adjustments relating to the recoverability and classification of recorded asset amounts or the amounts and classification of liabilities that might result from the outcome of this uncertainty.

Accounting Policies [Abstract]

Summary of Significant Accounting Policies

Basis of Presentation

The Company’s unaudited condensed 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 unaudited condensed 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 convertible debt, 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 unit (“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.

Unaudited Condensed Consolidated Financial Statements

The December 31, 2025 unaudited condensed consolidated balance sheet was derived from the annual audited consolidated financial statements included in the Company's Form 10-K as filed with the SEC on March 27, 2026 (the “Form 10-K”). The accompanying unaudited condensed consolidated balance sheet as of March 31, 2026, the unaudited condensed consolidated statements of operations and comprehensive loss, and stockholders’ equity for the three months ended March 31, 2026 and 2025, the unaudited condensed consolidated statements of cash flows for the three months ended March 31, 2026 and 2025, and the notes to such unaudited condensed consolidated financial statements are unaudited.

These unaudited condensed consolidated financial statements have been prepared in accordance with U.S. GAAP and the applicable rules and regulations of the SEC for interim financial information. As permitted under those rules, we condensed or omitted certain footnotes or other financial information that are normally required by GAAP for annual financial statements.

The unaudited condensed consolidated financial statements have been prepared on the same basis as the annual audited consolidated financial statements and, in management’s opinion, include all adjustments consisting of only normal recurring adjustments necessary for the fair presentation of the Company’s financial position as of March 31, 2026 and its results of operations for the three months ended March 31, 2026 and 2025 and cash flows for the three months ended March 31, 2026 and 2025. The results of operations for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the full fiscal year or any other period.

These unaudited condensed consolidated financial statements should be read in conjunction with the Company’s audited annual financial statements and notes thereto for the year ended December 31, 2025 included in the Form 10-K.

Principles of Consolidation

The unaudited condensed 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 the Company’s ability to access our cash and cash equivalents. If the Company is unable to access its cash and cash equivalents as needed, its financial position and ability to operate its business could be adversely affected. The Company’s marketable securities consist 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 unaudited condensed consolidated statements of operations and comprehensive loss, up to the amount of total outstanding accounts receivable to date. The Company’s top two customers from product sales, in the aggregate, accounted for 100% of total accounts receivable outstanding balances each as of March 31, 2026 and December 31, 2025, and accounted for 100% and 99% of total revenue for the three months ended March 31, 2026 and 2025, respectively.

Accounts Receivable Net

Accounts receivable net consisted of the following as of:


(in thousands)	March 31, 2026		December 31, 2025
Accounts receivable	$	10,810	$	13,877
Allowance for credit losses	(5,448)		(828)

Accounts receivable net	$	5,362	$	13,049

The Company assesses collectability by reviewing accounts receivable on a general basis where similar characteristics exist. In determining the amount of the allowance for credit losses, the Company considers historical collectability based on past due status, the age of the accounts receivable balances, credit quality of the Company’s customers based on ongoing credit evaluations, discussions with the customers, and other factors that may affect the Company’s ability to collect from customers. The increase in allowance for credit losses is based on updated estimates of collectability as of March 31, 2026.

Inventory

Inventory consisted of the following as of:


(in thousands)	March 31, 2026		December 31, 2025
Finished goods	$	49	$	49
Raw materials	594		594
Spare parts	39		41
Total	$	682	$	684

Intangible Assets

Intangible assets consisted of the following as of:


(in thousands)	March 31, 2026		December 31, 2025
Patents	$	362	$	367
Less accumulated amortization	(338)		(335)
Total intangible assets	$	24	$	32

The remaining useful life of the patent was 0.80 years as of March 31, 2026. For the three months ended March 31, 2026 and 2025, 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 within 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 their 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 unaudited condensed consolidated balance sheets. (See Note 6 for additional details)

In April 2025, the Company sold 35 of the total 183 acres of land held for sale for proceeds of $2.2 million, which approximates the carrying value.

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.

The decision was made to indefinitely suspend all further furanics platform development and plant operations for Origin 1. As a result, during the year ended December 31, 2025, the Company determined that indicators of impairment existed for the Origin 1 asset group. We evaluated the fair value of the Origin 1 asset group under an orderly liquidation approach as the primary valuation methodology, with corroborative consideration given to an alternative use undiscounted cash flow and eventual disposition approach. The fair value of the Origin 1 asset group was approximated at $18.0 million. As such, the Company recorded an impairment charge of $134.5 million.

The Company determined that indicators of impairment existed for Origin 2 asset group, as well, with the decision to indefinitely suspend the furanics platform development. The Company concluded the carrying costs of the labor, benefits and external engineering fees that had been capitalized to construction in progress for the Origin 2 asset group were no longer recoverable. As such, the Company recorded an impairment charge of $31.4 million to impairment of assets on the unaudited condensed consolidated statements of operations and comprehensive loss for the year ended December 31, 2025.

In addition, the Company had entered into a nonexclusive patent license agreement for use in connection with the production of Origin 2 and made nonrefundable payments totaling $12.9 million in prior years towards securing a license. The Company believes that the payments made towards the license agreement are no longer recoverable and recorded an impairment charge of $12.9 million to impairment of assets on the unaudited condensed consolidated statements of operations and comprehensive loss for the years ended December 31, 2025.

Convertible Notes

In November 2025, the Company entered into a securities purchase agreement (the “Purchase Agreement”) with an institutional purchaser, providing for the issuance in tranches of senior secured convertible notes (the “Convertible Notes”) with a principal face amount of up to $100.0 million and a 10.0% original issue discount, as discussed in Note 8. The Convertible Notes bear no interest rate (except upon event of default) and, unless earlier converted or redeemed, will mature on the date that is the thirty-month anniversary of the last day of the month in which the closing with respect to the applicable Convertible Notes occurs. The Convertible Notes will be convertible, at any time at the holder’s option, into shares of the Company’s common stock, par value $0.0001 per share, at an initial conversion price per share of $0.62616 (the “Conversion Shares”) and $18.78 (after the reverse stock split), which conversion price is subject to adjustment pursuant to the terms of the Convertible Notes. The conversion price is subject to customary adjustments upon any stock dividend, stock split, stock combination, reclassification, recapitalization, or similar transaction that proportionately decreases or increases the price of our common stock.

The Company has elected to account for the Convertible Notes at fair value under the fair value option, under which the Convertible Notes are initially measured at fair value and subsequently remeasured during each reporting period. Changes in fair value will be reflected within loss in fair value of convertible notes on the unaudited condensed consolidated statements of operations and comprehensive loss, except for the portions, if any, related to the instrument specific credit risk which would be recorded in other comprehensive (loss) income. Please see note 8 for further discussion.

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 common stock at an exercise price of at $11.50 per share; however, warrant holders will need to exercise 30 warrants for an aggregate exercise price of $345.00 to receive one share of common stock. No fractional shares will be issued upon the exercise of the warrants. As of March 31, 2026, 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 March 31, 2026.

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 50.0% or more of the Company’s 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 unaudited condensed consolidated balance sheets at fair value, with subsequent changes in their respective fair values recognized in the gain in fair value of common stock warrants liability within the unaudited condensed consolidated statements of operations and comprehensive loss 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.

Revenue Recognition

The Company’s revenues are from product sales and service agreements. The majority of the Company’s contracts with customers typically contain multiple products and services. The Company accounts 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 services 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 the Company fulfills its obligations under its product revenue and service agreements, the Company performs 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.

The Company accounts 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 the Company’s order confirmation, in exchange for future consideration, create enforceable rights and obligations on both parties and constitute a contract with a customer.

The Company’s 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. The Company identifies each performance obligation at contract inception and allocates the consideration to each distinct performance obligation based on the stand-alone selling price of each performance obligation. The Company’s services are tailored to each individual customer and the stand-alone selling prices are not directly observable. Because the Company’s service agreements include customers that are not in similar geographic markets and for different services, the Company uses the expected cost plus margin approach to estimate the stand-alone selling price for each of its performance obligations. The Company recognizes revenue from the service agreements over the period during which the services are performed and recognizes the associated costs as they are incurred.

In general, the Company recognizes revenue when, or as, its performance obligations under the terms of a contract with its customer are satisfied. For product sales, this happens when the Company transfers control of its products and risk of loss to the customer or when title passes upon shipment. Revenue is measured as the amount of consideration the Company expects to receive in exchange for transferring its 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 the Company expects to be entitled to in exchange for those goods or services. The Company has elected to treat shipping and handling activities as fulfillment costs.

Basic and Diluted Net Loss Per Share

Basic net loss per common share is calculated by dividing the net loss 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 per share is computed by dividing the net loss 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 per share calculation, common stock options, restricted stock unit (“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.

Segment Reporting [Abstract]

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 quarter ended March 31, 2026, the Company has determined that its Chief Executive Officer and Chief Financial Officer/Chief Operating Officer are the CODMs. The CODMs review the unaudited condensed 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 use net loss 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 and loss from operations for the Company’s single reportable segment are shown in the unaudited condensed consolidated statements of operations and comprehensive loss.

The following table presents the significant segment expenses that are regularly provided to the CODMs:


	Three Months Ended March 31,
(in thousands)		2026		2025
Total revenues		$	477	$	5,430

Debt Disclosure [Abstract]
Convertible Notes	Notes Payable 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 provides 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, which was amended through August 2022. The prepayment was to be credited against the purchase of products over the term of the Offtake Agreement and 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. The repayment in the amount of $2.7 million and $1.9 million were paid on September 1, 2024 and 2025, respectively, and $1.8 million is due on September 1, 2026 (inclusive of accrued but unpaid interest of 3.5% per annum). At March 31, 2026, the total remaining note principal outstanding balance was $1.7 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, 2025, the total remaining note principal outstanding balance was $1.7 million in notes payable, short-term, and unpaid accrued interest of less than $0.1 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. In September 2025, Origin Closures, LLC, a wholly-owned subsidiary of the Company, executed a Secured Promissory Note (the “Note”) with Starlinger & Co Gesellschaft m.b.H. (“Starlinger”), one of the Company’s manufacturers, in the principal amount of €9.5 million (approximately $11.2 million based on the exchange rate in effect on September 22, 2025) to finance the purchase of certain equipment used to produce PET sheet. The Note is effective as of October 7, 2025, the date that Starlinger executed and delivered the Note to the Company. Interest under the Note accrues at a rate of 10.6% per annum and the Note is to be repaid in semi-annual installments of principal and interest on the last day of April and October, respectively, beginning in April 2026 and continuing until fully repaid in October 2029. At March 31, 2026, the total note principal outstanding balance was $10.4 million, of which $2.7 million was recorded in notes payable, short-term and $7.7 million was recorded in notes payable, long-term with $1.1 million accrued interest outstanding was recorded in other liabilities, current. At December 31, 2025, the outstanding principal of $7.2 million, of which $2.8 million was recorded in notes payable, short-term and $4.4 million was recorded in notes payable, long-term with $0.1 million accrued interest outstanding was recorded in other liabilities, current. Convertible Notes In November 2025, the Company entered into the Purchase Agreement with an institutional purchaser, providing for the issuance in tranches of the Convertible Notes with a principal face amount of up to $100.0 million and a 10.0% original issue discount. The Convertible Notes bear no interest rate (except upon event of default) and, unless earlier converted or redeemed, will mature on the date that is the thirty-month anniversary of the last day of the month in which the closing with respect to the applicable convertible notes occurs. The Convertible Notes will be convertible, at any time at the holder’s option, into shares of the Company’s common stock, par value $0.0001 per share, at an initial conversion price per share of $0.62616 (the “Conversion Shares”) and $18.78 (after the reverse stock split), which conversion price is subject to adjustment pursuant to the terms of the Convertible Notes. The conversion price is subject to customary adjustments upon any stock dividend, stock split, stock combination, reclassification, recapitalization, or similar transaction that proportionately decreases or increases the price of our common stock. At the initial closing, the Company issued $16.7 million in aggregate principal amount of Convertible Notes and received $15.0 million, net with the original issue discount. The outstanding balance of the Convertible Notes was $7.0 million and $15.0 million as of March 31, 2026 and December 31, 2025, respectively. The Company utilized the Black-Scholes Merton model to value the Convertible Notes. The key inputs and assumptions used in the valuation model, including the risk-free interest rate and the expected volatility of the price of the underlying stock, were utilized to estimate the fair value of the associated liability. The Company measures the fair value at each reporting period, with changes in fair value recorded within loss in fair value of convertible notes on the unaudited condensed consolidated statements of operations and comprehensive loss. The Company recognized a loss of $1.9 million which included 8% premium for the convertible notes cash repayment of $0.6 million in the changes in fair values of convertible debt during three months ended March 31, 2026. The Company was in compliance with all financial covenants as of March 31, 2026.

Revenues	3 Months Ended
Revenues	Mar. 31, 2026
Revenue from Contract with Customer [Abstract]
Revenues	Revenues The Company recognizes revenues when, or as, its performance obligations under the terms of a contract with its customer are satisfied (see Note 2 for additional details). The Company generally procures, will produce, and sells product to be utilized in the manufacturing of finished products, for which it recognizes revenue upon shipment. Currently, the majority of the Company’s revenue is generated from the supply chain activation program in which the Company purchases materials from various vendors and sells them to its customers for a moderate margin as it establishes the logistics and invoicing capabilities for its own products. The Company’s service contracts generally pay the Company at the commencement of the agreement and then at additional intervals as outlined in each contract. The Company recognizes contract liabilities for such payments and then recognizes revenue as it satisfies the related performance obligations. To the extent collectible revenue recognized under this method exceeds the consideration received, the Company recognizes contract assets for such unbilled consideration. The Company recognizes 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 during the three months ended March 31, 2026 and 2025. Therefore, deferred revenue was zero.

- Definition

The entire disclosure of revenue from contract with customer to transfer good or service and to transfer nonfinancial asset. Includes, but is not limited to, disaggregation of revenue, credit loss recognized from contract with customer, judgment and change in judgment related to contract with customer, and asset recognized from cost incurred to obtain or fulfill contract with customer. Excludes insurance and lease contracts.

Commitments and Contingencies	3 Months Ended
Commitments and Contingencies	Mar. 31, 2026
Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments The Company entered into multiple purchase agreements with various vendors to purchase equipment to fulfill a near-term demand for its PET closures during 2024. Pursuant to the agreements, the Company committed to purchase the equipment with installment payments. The Company made payments totaling $41.8 million through March 31, 2026, and has recorded the amount in property, plant, and equipment, net on the unaudited condensed consolidated balance sheets. The Company is obligated to make additional payments toward the remaining balances of up to approximately $18.1 million subject to the achievement of certain milestones. 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 March 31, 2026. 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 no and $0.1 million payments for the annual royalties made during the three months ended March 31, 2026 and 2025, respectively. The Company enters 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 United States District Court for the Eastern District of California (the “Court”) 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.)). 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 alleged 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 has sought unspecified damages, fees and costs, and governance changes. In October 2025, the Company entered into binding agreements to settle the putative shareholder class action lawsuit and the related derivative litigation. On January 7, 2026, the Court granted preliminary approval of the settlement of the securities class action, and on January 20, 2026, the Court granted final approval of the settlement of the derivative litigation.

Subsequent Events [Abstract]
Subsequent Events	Subsequent Events On April 28, 2026, the Board of Directors of the Company approved a reduction in workforce, which was effective on May 1, 2026, This reduced Origin's workforce by approximately 59%, while maintaining the necessary support for the Plan of Dissolution, resulting in approximately $14.0 million decrease in annual operating expenses. Origin anticipates that it will incur approximately $2.1 million in restructuring charges in connection with the workforce reduction, consisting of cash expenditures for severance and benefits costs. Origin expects to incur the majority of expenses related to the workforce reduction by the end of the second quarter of 2026. These estimated charges are subject to a number of assumptions, including legal requirements in various jurisdictions, and actual results may differ materially from these estimates. The Company may incur additional costs not currently contemplated due to events that may occur as a result of, or that are associated with, the workforce reduction. In connection with the reduction-in-force above, John Bissell has stepped down as Chief Executive Officer, effective May 1, 2026. Mr. Bissell will continue to serve on the Board of Directors. Matt Plavan, our Chief Financial Officer and Chief Operating Officer has been appointed Interim Chief Executive Officer, effective May 1, 2026. On May 14, 2026, the Board of Directors of the Company approved a Management Incentive Plan (a "MIP") in connection with the Plan of Dissolution. The purpose of the MIP is to establish a performance-based incentive bonus opportunity that aligns the interests of key employees with those of the Company's stockholders. The MIP rewards participants only to the extent that proceeds realized from the sale of specified Company assets exceed designated minimum value thresholds.

Notes Payable	3 Months Ended
Notes Payable	Mar. 31, 2026
Debt Disclosure [Abstract]
Notes Payable	Notes Payable 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 provides 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, which was amended through August 2022. The prepayment was to be credited against the purchase of products over the term of the Offtake Agreement and 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. The repayment in the amount of $2.7 million and $1.9 million were paid on September 1, 2024 and 2025, respectively, and $1.8 million is due on September 1, 2026 (inclusive of accrued but unpaid interest of 3.5% per annum). At March 31, 2026, the total remaining note principal outstanding balance was $1.7 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, 2025, the total remaining note principal outstanding balance was $1.7 million in notes payable, short-term, and unpaid accrued interest of less than $0.1 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. In September 2025, Origin Closures, LLC, a wholly-owned subsidiary of the Company, executed a Secured Promissory Note (the “Note”) with Starlinger & Co Gesellschaft m.b.H. (“Starlinger”), one of the Company’s manufacturers, in the principal amount of €9.5 million (approximately $11.2 million based on the exchange rate in effect on September 22, 2025) to finance the purchase of certain equipment used to produce PET sheet. The Note is effective as of October 7, 2025, the date that Starlinger executed and delivered the Note to the Company. Interest under the Note accrues at a rate of 10.6% per annum and the Note is to be repaid in semi-annual installments of principal and interest on the last day of April and October, respectively, beginning in April 2026 and continuing until fully repaid in October 2029. At March 31, 2026, the total note principal outstanding balance was $10.4 million, of which $2.7 million was recorded in notes payable, short-term and $7.7 million was recorded in notes payable, long-term with $1.1 million accrued interest outstanding was recorded in other liabilities, current. At December 31, 2025, the outstanding principal of $7.2 million, of which $2.8 million was recorded in notes payable, short-term and $4.4 million was recorded in notes payable, long-term with $0.1 million accrued interest outstanding was recorded in other liabilities, current. Convertible Notes In November 2025, the Company entered into the Purchase Agreement with an institutional purchaser, providing for the issuance in tranches of the Convertible Notes with a principal face amount of up to $100.0 million and a 10.0% original issue discount. The Convertible Notes bear no interest rate (except upon event of default) and, unless earlier converted or redeemed, will mature on the date that is the thirty-month anniversary of the last day of the month in which the closing with respect to the applicable convertible notes occurs. The Convertible Notes will be convertible, at any time at the holder’s option, into shares of the Company’s common stock, par value $0.0001 per share, at an initial conversion price per share of $0.62616 (the “Conversion Shares”) and $18.78 (after the reverse stock split), which conversion price is subject to adjustment pursuant to the terms of the Convertible Notes. The conversion price is subject to customary adjustments upon any stock dividend, stock split, stock combination, reclassification, recapitalization, or similar transaction that proportionately decreases or increases the price of our common stock. At the initial closing, the Company issued $16.7 million in aggregate principal amount of Convertible Notes and received $15.0 million, net with the original issue discount. The outstanding balance of the Convertible Notes was $7.0 million and $15.0 million as of March 31, 2026 and December 31, 2025, respectively. The Company utilized the Black-Scholes Merton model to value the Convertible Notes. The key inputs and assumptions used in the valuation model, including the risk-free interest rate and the expected volatility of the price of the underlying stock, were utilized to estimate the fair value of the associated liability. The Company measures the fair value at each reporting period, with changes in fair value recorded within loss in fair value of convertible notes on the unaudited condensed consolidated statements of operations and comprehensive loss. The Company recognized a loss of $1.9 million which included 8% premium for the convertible notes cash repayment of $0.6 million in the changes in fair values of convertible debt during three months ended March 31, 2026. The Company was in compliance with all financial covenants as of March 31, 2026.
