Stockholders' Equity

Stockholders' Equity Note [Abstract]

Stockholders' Equity

Stockholders’ Equity

As of March 31, 2022, 1,010,000,000 shares, $0.0001 par value per share are authorized, of which, 1,000,000,000 shares are designated as Common Stock and 10,000,000 shares are designated as Preferred Stock.

Common Stock

Holders of the Common Stock are entitled to dividends when, as, and if, declared by the Board, subject to the rights of the holders of all classes of stock outstanding having priority rights to dividends. As of March 31, 2022, the Company had not declared any dividends. The holder of each share of Common Stock is entitled to one vote. There were 141,418,989 and 141,418,989 shares of Common Stock (including 4,500,000 Sponsor Vesting Shares not indexed to equity) outstanding as of March 31, 2022 and December 31, 2021, respectively.

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 of directors, which shall not be less than 85% of the lower of the fair market value of our Common Stock on the first day of an offering or on the date of purchase.

Initially, following adoption of the ESPP, the maximum number of shares of our Common Stock that may be issued under the ESPP was 1,846,710. The ESPP contains an “evergreen” share reserve feature that automatically increases the number of shares of Common Stock reserved for issuance under the plan on January 1 of each year for a period of ten years commencing on January 1, 2022 and ending on (and including) January 1, 2031 in an amount equal to the lesser of (1) one percent (1%) of the fully-diluted shares of our Common Stock on December 31st of the preceding calendar year, (2) 3,693,420 of Common Stock, or (3) such lesser number of shares as determined by our board of directors. On January 1, 2022, the number of shares of Common Stock reserved for issuance under the ESPP was automatically increased by 1,875,780. As a result, as of March 31, 2022, the number of shares available for issuance under the ESPP was 3,722,490. 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.

To date no stock has been offered or issued to employee's 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 Plans, each as amended (together, the “Stock Plans”). Upon closing of the Business Combination, awards under the 2010 Stock Incentive Plan and 2020 Equity Incentive Plan were converted at the Exchange Ratio 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, performance-based stock awards, and other awards. The Company has granted incentive stock options, RSU awards, and performance 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 Plan generally vest 25% one year from the vesting commencement date and 1/36th per month thereafter, although certain arrangements call for vesting over other periods. Options granted to non-employees under the Stock Plan vest over periods determined by the Board (generally immediate to four years). RSU awards granted to employees under the 2021 Equity Incentive Plan require a service period of three years and generally vest 33.3% annually over the three-year service period. Under the Stock Plans, the fair value of RSU awards and performance-based stock 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

performance-based stock awards are subject to vesting based on a performance-based condition and a service-based condition. The performance-based stock awards will vest in a percentage of the target number of shares between 0% and 300%, depending on the extent the performance conditions are achieved. At March 31, 2022, the Company determined the performance conditions are not probable of being met, therefore no stock compensation was accrued.

Initially, following adoption of the 2021 Equity Incentive Plan, there were 18,467,109 shares of Common Stock reserved for issuance under the Stock Plans. The 2021 Equity Incentive Plan contains an “evergreen” share reserve feature that automatically increases the number of shares of Common Stock reserved for issuance under the plan on January 1 of each year for a period of ten years commencing on January 1, 2022 and ending on (and including) January 1, 2031 in an amount equal to five percent (5%) of the fully-diluted Common Stock on December 31 of the preceding year unless our board acts prior to January 1 to increase the share reserve by a lesser amount. The number of shares added to the share reserve on January 1 of a given year is reduced automatically to the extent necessary to avoid causing the share reserve to exceed fifteen percent (15%) of the fully-diluted Common Stock on December 31 of the preceding year. On January 1, 2022, the number of shares of Common Stock reserved for issuance under the 2021 Equity Incentive Plan was automatically increased by 9,378,902 shares pursuant to the 2021 Plan’s “evergreen” provision. As a result, as of March 31, 2022, there were 27,846,011 shares of Common Stock reserved under the Stock Plans.

The following tables summarize the activity under the Stock Plans:


	Outstanding Options	Weighted Average Exercise Price		Weighted Average Remaining Contractual Life (in years)
Balance at December 31, 2021	7,892,857	$	0.19	7.31

Vested and expected to vest at March 31, 2022	7,775,437

During the quarter ended March 31, 2022, the Company did not grant any stock options. As of March 31, 2022 and December 31, 2021, there were 20,070,574 and 7,667,247 awards, respectively, available for grant under the Stock Plans. As of March 31, 2022 and December 31, 2021 there were 4,231,608 and 4,130,184 exercisable options, respectively. The aggregate intrinsic value of options vested and expected to vest at March 31, 2022 is $49.7 million. As of March 31, 2022, the Company had stock-based compensation of $7.0 million related to unvested stock options not yet recognized that are expected to be recognized over an estimated weighted average period of 2.3 years.

The Company issued 2,920,732 of performance and market-based stock options during 2020. During the quarter ended March 31, 2021, the Company modified the vesting schedule of 529,119 of these performance and market based stock options such that vesting at 1/48th per month would commence upon signing of the Business Combination. The Company entered into the Merger Agreement on February 16, 2021 resulting in the commencement of expense recognition related to these 529,119 options during the quarter ended March 31, 2021. During the three months ended March 31, 2021, stock compensation expense related to these performance and market based stock options was $2.9 million. For the remaining 2,391,613 performance and market-based stock options, expense commenced on the close date of the Merger, June 25, 2021, as that is the date when the performance condition was achieved.

RSU award and performance-based stock award activity for the three months ended March 31, 2022 was as follows:


	Restricted Stock Outstanding
	Outstanding	Weighted-average grant date fair value
Balance at December 31, 2021	2,907,005	7.35
Granted - RSU awards	221,040	5.33
Granted - performance-based stock awards	372,000	5.33
Balance March 31, 2022	3,500,045	7.05
Expected to vest	990,545

The RSU awards, which upon vesting entitle the holder 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. As of March 31, 2022, the performance conditions for the granted performance-based stock awards were not probable of being met, therefore no performance award stock compensation has been recorded. No RSU awards or performance-based stock awards vested during three months ended March 31, 2022. No RSU awards or performance-based stock awards were outstanding at March 31, 2021. Total remaining compensation expense for RSU awards to be recognized under the 2021 Equity Incentive Plan is $6.0 million as of March 31, 2022 and will be amortized on a straight-line basis over the remaining vesting periods of approximately three years for RSU awards. Total remaining compensation expense for performance-based stock awards to be recognized under the 2021 Equity Incentive Plan is $17.7 million as of March 31, 2022 and will be recognized over the requisite service periods once the performance-based conditions are deemed to be probable.

During the three months ended March 31, 2022 and 2021, stock compensation expense of $0.7 million and $0.5 million, respectively, was recognized in general and administrative expenses on the unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). During the three months ended March 31, 2022 and 2021 stock compensation expense of $0.2 million and $0.1 million, respectively, was recognized in research and development expenses on the unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).

Consortium Agreement	Consortium Agreement The Company has entered into consortium agreements with counterparties to collaborate on development of a process to commercialize bio-based, decarbonizing materials for application on an industrial scale at a competitive price. The agreements expire once performance of the research and development program has been completed. At the time the consortium agreements were entered into, several of the counterparties were related parties (Note 11). In 2020, an additional counterparty, that is an unrelated party, was added to the consortium agreement. During three months ended March 31, 2022 and 2021, the Company received $0.0 million and $0.5 million, respectively under the consortium agreement which was recorded as other income, net in the Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).

Other Liabilities Disclosure [Abstract]
Other Liabilities, Long-term	Other Liabilities, Long-termIn September 2019, the Company entered into a $5.0 million prepayment agreement with a counterparty for the purchase of products from Origin 2. The prepayment is to be made in two equal installments: the first $2.5 million was in October 2019 and the remaining $2.5 million is due within 30 days of the customer confirming that a sample from Origin 1 meets the customer’s specifications. The Company and customer agreed to work in good faith to execute an Offtake Agreement, the agreed terms of which are set forth in the prepayment agreement, whereby 100% of the prepayment will be applied against future purchases. The prepayment agreement provides the customer a capacity reservation of up to a specified annual volume of product from Origin 1 for a term of ten years, pursuant to the terms of an Offtake Agreement. At March 31, 2022 and December 31, 2021, the total amount outstanding on this agreement was $2.5 million.

Related Party Transactions	3 Months Ended
Related Party Transactions	Mar. 31, 2022
Related Party Transactions [Abstract]
Related Party Transactions	Related Party Transactions Consortium Agreements In December 2016, the Company entered into a consortium agreement (Note 9) with two Legacy Origin Series B preferred stock investors to collaborate on development of a process to commercialize bio-based, decarbonizing materials for application on an industrial scale at a competitive price. Under the consortium agreement, the Company received $0.5 million. The agreement expires once performance of the research and development program has been completed. In August 2018, the agreement was amended, whereby a Legacy Origin Series C preferred stock investor (the “Legacy Origin Series C Investor”, and collectively with the two Legacy Origin Series B investors, the “Legacy Origin Investors”) was added to the agreement and committed to invest $1.5 million of research and development in the consortium. As of March 31, 2022, the Legacy Origin Series C Investor had not invested any funds in the consortium. Offtake Agreements The Company maintains four separate offtake supply agreements with Legacy Origin stockholders or affiliates of Legacy Origin stockholders (the “Offtake Agreements”). Pursuant to the Offtake Agreements, the Company will construct manufacturing plants with specific capacity and product quality requirements within certain timeframes for the manufacture of product for sale to the counterparties to the agreements, and the counterparties will make minimum annual purchases at a set price, subject to adjustments, all as defined in the agreements. The Offtake Agreements allow the customers to terminate the agreements if specified construction and product delivery requirements are not satisfied. For example, under two of these agreements, if Origin 1 has not commenced commercial operation by December 31, 2021 or Origin has not delivered specified product volume from Origin 1 by September 30, 2022, then the customer may terminate the agreement and any outstanding secured promissory notes resulting from advance payments made to Origin will become due immediately (see Note 12). These outstanding obligations, together with accrued interest, totaled an aggregate of $11.0 million and $10.9 million as of March 31, 2022 and December 31, 2021 respectively (see Note 12). These agreements also require the Company to pay liquidated damages up to an aggregate of $0.9 million if Origin 1 has not commenced commercial operation by December 31, 2021 or the Company has not delivered specified product volume from Origin 1 by September 30, 2021. In November 2021, one counterparty agreed to waive compliance with the milestones and their right to liquidated damages until June 30, 2022 and in December 2021 the other counterparty agreed to waive compliance with the milestones and their right to liquidated damages through March 31, 2022. If the liquidated damage deferral is not further extended by this counterparty, the liquidated damages would begin to accrue on April 1, 2022 in accordance with the agreement. A third offtake agreement can be terminated by the counterparty if commercial operation or delivery of product from Origin 1 has not occurred by December 31, 2022. The Company believes enforcement of the liquidated damages provisions is not probable and expects to secure amendments to these offtake agreements pursuant to its ongoing discussions with these customers. However, the Company cannot guarantee that it will be successful in amending these offtake agreements. One of the Offtake Agreements provides the counterparty the option, exercisable within 1 year of the first delivery of product from Origin 1, to enter into a contract to purchase a range of quantities of product from Origin 2 for a maximum term of 10 years. If the option is exercised and the Company directly or indirectly constructs Origin 2, the Company must either enter into an agreement with the counterparty within 90 days or pay a fee. There are no impacts to these unaudited condensed consolidated financial statements from this stipulation. Stockholder Convertible Notes Payable In November 2019, the Company entered into secured convertible note agreements (“Bridge Notes”) with certain Legacy Origin preferred stockholders, whereby the Company can borrow up to $6.0 million. The Bridge Notes bore an annual interest rate of 10% and matured on March 31, 2021, unless converted. If the Company issues shares of a new series of preferred stock prior to maturity, the outstanding principal and unpaid accrued interest will convert at 70% of the per share price of the new series of preferred stock. Upon a liquidation event, as defined in the agreements, the Company would be required to repay purchasers in cash an amount equal to 200% of the outstanding principal amount plus the outstanding principal and accrued interest. The Bridge Notes were collateralized by substantially all of the Company’s assets. The conversion and liquidation features were deemed to be derivatives under ASC 815 (see Note 6) and separately measured and recognized from the Bridge Notes through a debt discount. In January 2021, the Company amended the Bridge Notes to extend the maturity date from March 31, 2021 to September 30, 2021. The amendment also added a SPAC transaction to the conversion provision such that the Bridge Notes convert if the Company issues at least $50 million of shares of a new series of preferred stock or closes a SPAC transaction (each a “Qualified Financing”) prior to maturity. In a Qualified Financing that is a preferred stock issuance, the notes convert at 70% of the cash price paid per share for the preferred shares. In a Qualified Financing that is a SPAC transaction, the notes convert at the lesser of (i) 70% of the per share value attributed to the shares of the Company’s common stock as set forth in the Merger Agreement or (ii) the per share value that would be attributed to the Company’s common stock assuming a pre-transaction valuation of the Company in connection with the SPAC transaction of $700 million. These notes fully converted into the Company common stock upon consummation of the Business Combination (see Note 4). In February 2021 the Company issued $10.0 million of new, unsecured convertible notes (the “Convertible Notes”). The Convertible Notes bore an annual interest rate of 8% and matured on September 30, 2021, unless converted. If the Company issues at least $50 million worth of shares of a new series of preferred stock prior to maturity or closes a SPAC transaction (each a “Qualified Financing”), the outstanding principal and unpaid accrued interest will convert at 80% of the per share price of the new series of preferred stock or, in the case of a SPAC transaction, at 80% of the per share value attributed to the shares of the Company’s common stock as set forth in the Merger Agreement. Upon a Change of Control (other than a Qualified Financing), as defined in the Convertible Notes, the Company will repay purchasers in cash an amount equal to the outstanding principal and accrued interest plus a repayment premium equal to 100% of the outstanding principal amount of the notes. Debt issuance costs are recorded against the outstanding payable balance. These notes fully converted into the Company common stock upon consummation of the Business Combination (see Note 4). Legacy Stockholder Note In November 2016, the Company received a $5 million prepayment from a Legacy Origin stockholder for product from Origin 1 pursuant to an Offtake Agreement (see Note 11). The prepayment was to be credited against the purchase of products over the term of the Offtake Agreement. The prepayment was secured by a promissory note (the “Promissory Note”) to be repaid in cash in the event that the prepayment could not be credited against the purchase of product, for example, if Origin 1 was never constructed. The Promissory Note was collateralized substantially by Origin 1 and other assets of Origin Material Canada Pioneer Limited. In May 2019, the Company and legacy stockholder amended the Offtake Agreement and Promissory Note. The amendment added accrued interest of $0.2 million to the principal balance of the prepayment and provided for the prepayment amount to be repaid in three annual installments rather than being applied against the purchase of product from Origin 1. The Promissory Note would bear interest at 3.50% per annum and be repaid in three installments of $2.2 million, $2.1 million, and $2.1 million (inclusive of accrued but unpaid interest) on December 20, 2024, December 19, 2025, and December 18, 2026, respectively. At March 31, 2022 and December 31, 2021, the total debt outstanding was $5.2 million. Legacy Related Party Other Liabilities, Long-term In November 2016, the Company received a $5 million prepayment from a legacy stockholder for product from Origin 1 pursuant to an Offtake Agreement (see Note 11). The prepayment is to be credited against the purchase of products from Origin 1 over the term of the Offtake Agreement. Specifically, repayment is effected by applying a credit to product purchases each month over the first five years of operation of Origin 1 up to $7.5 million, which is equal to 150% of the prepayment amount. If product purchases are not sufficient to recover the advances, the application of the credit to purchases as payment of the advances will continue until fully repaid. The prepayment is secured by a note to be repaid in cash in the event the prepayment cannot be credited against the purchase of product, for example, if Origin 1 is never constructed.

Earnings Per Share [Abstract]

Basic and Diluted Net Income (Loss) Per Share

The following table sets forth the computation of basic and diluted net income (loss) per share attributable to common stockholders, which excludes Sponsor Vesting Shares which are legally outstanding, but subject to return to the Company. Basic net income (loss) per share is computed by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period. Diluted net income (loss) per share is computed by dividing net income (loss) for the period by the weighted-average number of common shares outstanding during the period, plus the dilutive effect of the stock options, RSU awards, and convertible preferred stock warrants, as applicable pursuant to the treasury stock method, and the convertible notes, as applicable pursuant to the if-converted method.

Commitments and Contingencies Disclosure [Abstract]
Commitments and Contingencies	Commitments and Contingencies Commitments In connection with the closing of the Business Combination, the Company entered into the Investor Rights Agreement on June 25, 2021 (the “Investor Rights Agreement”), pursuant to which the holders of Registrable Securities (as defined therein) became entitled to, among other things, customary registration rights, including demand, piggy-back and shelf registration rights. The Investor Rights Agreement also provides that the Company will pay certain expenses relating to such registrations and indemnify the registration rights holders against (or make contributions in respect of) certain liabilities which may arise under the Securities Act. On July 15, 2021, the Company registered the Registrable Securities for resale pursuant to a registration statement on Form S-1, as amended (File No. 333-257931) that became effective on July 30, 2021. In May 2018, the Company executed operating and maintenance agreements for certain services, to facilitate the development and thus bring Origin 1 to the condition necessary for its intended use, commencing in different periods between July 2018 and September 2019, and all generally for five-year periods. The agreements are generally automatically extended for one-year periods thereafter. The agreements include annual fixed payments subject to escalation clauses at the beginning of each calendar year, as defined in the agreement. The minimum fixed payments are $0.4 million (in Canadian dollars) per year over the fixed term. Certain of the agreements include quantities that are based on volumes, as defined in the applicable agreements. The Company is also responsible for applicable taxes under these agreements. During the three months ended March 31, 2022 and 2021, the total amount capitalized into Property, Plant and Equipment, Net under the agreement was $0.1 million. In May 2019, the Company also concurrently executed a take-or-pay steam supply agreement commencing by October 1, 2019, through December 31, 2022, whereby the Company will receive up to 25% for the first year and 50% thereafter of the steam generated, up to 140,000 MMBTUs per year. The price paid for the steam is based on a fixed amount plus the supplier’s cost of natural gas, as defined in the agreement. During the three months ended March 31, 2022 and 2021, the total amount capitalized into Property, Plant and Equipment, Net under the agreement was $0.1 million. In May 2018, the Company entered into a joint development agreement (the “JDA”) with a legacy stockholder to evaluate alternative uses for one of the Company’s products. The term of the JDA is the later of (i) 3 years from the JDA effective date and (ii) the final expected development program completion date as specified in the JDA. There were no expenses under this agreement for the three months ended March 31, 2022 or 2021. Patent licenses In July 2017, the Company entered into a patent license agreement for $0.1 million, which expires in December 2025 upon expiration of the last to expire of the licensed patents. Under this agreement, the Company will pay minimum royalty payments of $5,000 per year and, if the Company develops and sells certain products based on the licensed patents, up to a maximum of $25,000 per year. Certain products that Origin is currently developing and anticipates selling are expected to utilize these patents. In December 2016, the Company entered into a patent license agreement for $0.5 million, which expires upon expiration of the last to expire of the licensed patents. Under this agreement, if the Company develops and sells specific products based on the patents, the Company would pay a royalty up to a cumulative $0.5 million from Origin 1, whereby no further payments will be due for any production at Origin 1. If production of those products occurs at subsequent 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 million per facility. Certain products that the Company is currently developing and anticipates selling are expected to utilize these patents. No payments were made during the three months ended March 31, 2022 or 2021. In November 2016, the Company entered into a patent license agreement for $0.0 million, which expires upon expiration of the patent. Under this agreement, if the Company produces products based on the patent, the Company will pay an annual royalty upon commencement of operations on Origin 1 of $0.0 million up to a cumulative $1.0 million. The pipeline of Company products and sales are not currently expected to be subject to this patent. No payments were made during the three months ended March 31, 2022 or 2021. In August 2015, the Company entered into a 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 and anticipates selling are expected to utilize these patents. No payments were made during the three months ended March 31, 2022 or 2021. In June 2011, the Company entered into a nonexclusive patent license agreement, which expires upon expiration of the licensed patent. Under this agreement, the Company pays a royalty of $5,000 annually and if the Company develops and sells specific products based on the patent, 0.4% of net sales. The pipeline of Company products and sales are not currently expected to be subject to this patent. 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. Although the Company cannot predict the outcome of these matters when they arise, in the opinion of management, any liability arising from them will not have a material adverse effect on the consolidated financial position, results of operations, or liquidity of the Company. At March 31, 2022 and December 31, 2021, there were no claims or legal proceedings.

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 will receive funding for eligible expenditures through March 31, 2023 up to the lesser of approximately 18.48% of eligible costs and $23 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 the fifth year following the earlier of (i) the year in which the Company completes construction of Origin 1 or (ii) March 2023. The maximum amount to be repaid by the Company under the R&D Agreement is 1.25 times the actual funding received, subject to the following repayment ceiling formula. Repayment of the funding will be reduced by 50% if the Company begins construction before December 31, 2024 of one or more commercial plants that operate in Canada, with costs exceeding $500 million (in Canadian dollars), and the plants being constructed and operational within 30 months of the final investment decision, as defined in the R&D Agreement. Once begun, repayments will be paid annually by April of each year through March 31, 2037. Payments will be determined by a formula of the funded amount based on the fiscal year gross business revenue, as defined in the R&D Agreement. The Company recorded a liability of $6.9 million and $6.8 million at March 31, 2022 and December 31, 2021, respectively, on the Condensed Consolidated Balance Sheets in Canadian government research and development program liability.

Business Combination and Asset Acquisition [Abstract]
Business Combination	Business Combination On June 25, 2021, Artius and Micromidas, Inc. (now known as Origin Materials Operating Inc., "Legacy Origin") completed the Business Combination pursuant to the Merger Agreement with Legacy Origin surviving the merger as a wholly owned subsidiary of Artius, which became Origin Materials, Inc. Cash proceeds from the Business Combination totaled approximately $467.5 million, which included funds held in Artius’s trust account and the completion of the concurrent PIPE and Backstop Financing. In accordance with the terms and subject to the conditions of the Merger Agreement, at the effective time of the Merger, (i) all shares of Legacy Origin’s Series A, Series B, and Series C Preferred Stock, and Common Stock (collectively, “Legacy Origin Stock”) issued and outstanding immediately prior to the effective time of the Merger were converted into the right to receive their pro rata portion of shares of Company Common Stock (the “Common Stock”) issued as Merger consideration; (ii) holders of Legacy Origin’s Convertible Notes Payable, plus accrued interest also received shares of Company Common Stock; (iii) each option exercisable for Legacy Origin Stock that was outstanding immediately prior to effective time of the Merger was assumed and continues in full force and effect on the same terms and conditions as were previously applicable to such options, subject to adjustments to exercise price and number of shares Common Stock issuable upon exercise based on the final conversion ratio calculated in accordance with the Merger Agreement. Additionally, as part of the consideration transferred, stockholders of Legacy Origin and Artius were given the right to additional shares in the Company. These shares vest to the holder upon the share price of the Company reaching certain targets over a future period (“Earnout Shares”, see Note 13). The Company accounted for the Business Combination as a reverse recapitalization, which is the equivalent of Legacy Origin issuing stock for the net assets of Artius, accompanied by a recapitalization, with Artius treated as the acquired company for accounting purposes. The determination of Artius as the “acquired” company for accounting purposes was primarily based on the fact that subsequent to the Business Combination, Legacy Origin will comprise all of the ongoing operations of the combined entity, a majority of the governing body of the combined company and Legacy Origin’s senior management will comprise all of the senior management of the combined company. The net assets of Artius were stated at historical cost with no goodwill or other intangible assets recorded. Reported results from operations included herein prior to the Business Combination are those of Legacy Origin. The shares and corresponding capital amounts and loss per share related to Legacy Origin’s outstanding convertible preferred stock and Common Stock prior to the Business Combination have been retroactively restated to reflect the conversion ratio established in the Merger Agreement (1.00 Legacy Origin share for approximately 2.11 shares of the Company, the "Exchange Ratio").

The following table sets forth a summary of the activities of the Company’s redeemable convertible preferred stock warrant liability and embedded components of the stockholder convertible notes payable, which represents a recurring measurement that is classified within Level 3 of the fair value hierarchy wherein fair value is estimated using significant unobservable inputs:


Redeemable Convertible Preferred Stock Warrants	Three Months Ended March 31,
(in thousands)	2022		2021
Beginning warrants liability balance	$	—	$	19,233
Change in fair value of warrants liability	—		48,109

Ending warrant liability balance	$	—	$	67,342

Embedded Derivative - Stockholder Convertible Notes Payable	Three Months Ended March 31,
(in thousands)	2022		2021
Beginning derivative liability balance	$	—	$	1,239
Change in fair value of derivative liability	—		391
Additional derivative liability	—		2,197
Ending derivative liability balance	$	—	$	3,827

The Company performs routine procedures such as comparing prices obtained from independent sources to ensure that appropriate fair values are recorded. 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. All of the Company’s cash, cash equivalents, restricted cash, marketable securities and foreign currency derivative contracts are classified within Level 1 or Level 2 because the Company’s cash, cash equivalents, restricted cash, marketable securities and foreign currency derivative contracts are valued using quoted market prices or alternative pricing sources and models utilizing observable market inputs. 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 redeemable convertible preferred stock warrants liability and the derivative liability are 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.

As of March 31, 2022 and December 31, 2021, the carrying values of cash and cash equivalents, accounts payable and accrued liabilities approximate their respective fair values due to their short-term nature.

Marketable Securities

The following table summarizes, by major security type, 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 as of March 31, 2022 and December 31, 2021. The fair value as of March 31, 2022 and December 31, 2021 are as follows:

Any realized gains and losses and interest income are included in other income on the consolidated statements of operations and comprehensive income (loss).

During the three months ended March 31, 2022, we sold marketable securities for proceeds of $1,240.8 million and realized a loss of $(0.5) million as a result of those sales. We regularly review our available-for-sale marketable securities in an unrealized loss position and evaluate the current expected credit loss by considering factors such as historical

experience, market data, issuer-specific factors, and current economic conditions. The aggregate fair value of the marketable securities in unrealized loss position was $351.2 million and $346.3 million as of March 31, 2022 and December 31, 2021, respectively, none of which have been in the continuous unrealized loss for more than twelve months. The unrealized losses were attributable to changes in interest rates that impacted the value of the investments, and not increased credit risk. Accordingly, we have not recorded an allowance for credit losses associated with these investments.

The contractual maturities of the investments classified as marketable securities are as follows (in millions):


	As of March 31, 2022
(in thousands)	Mature within one year		Mature after one year through two years		Mature over two years		Fair Value

Redeemable Convertible Preferred Stock Warrant Liability

At March 31, 2021, the fair value of the preferred stock warrants was determined using the probability-weighted expected return method which estimates the fair value of the warrants through an analysis of future values for the Company, assuming various future outcomes. At March 31, 2021, due to the increasing likelihood of the merger, the Black-Scholes option pricing model was not necessary.

Derivative Asset and Liability

Beginning in the year ended December 31, 2021, the Company entered into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk related to marketable securities. Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized as other income (expense). During the three months ended March 31, 2022 and 2021, the Company recognized a net loss of $0.8 million and $0.0 million, respectively, on the fair value adjustment of the foreign currency derivative contracts.

There is no provision for income taxes because the Company has incurred operating losses since inception. The Company’s effective income tax rate was 0% for the three months ended March 31, 2022 and 2021 and the realization of any deferred tax assets is not more likely than not.

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 the post-Business Combination Origin Materials, Inc. and its consolidated subsidiaries. The Company’s mission to help enable the world’s transition to sustainable materials by replacing petroleum-based materials with decarbonized materials in a wide range of end products, such as food and beverage packaging, clothing, textiles, plastics, car parts, carpeting, tires, adhesives, soil amendments and more. The Company’s technology can convert 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. The Company’s products are intended to compete directly with petroleum-derived products on both performance and price, as well as provide a significant unit cost advantage over products made from other low-carbon feedstocks. The Company is currently developing and constructing its first manufacturing plant in Ontario, Canada ("Origin 1"), which is expected to become operational in 2022. The Company is also currently in the planning phase for the construction of a significantly larger manufacturing plant ("Origin 2"), with which is expected to become operational in 2025. On June 25, 2021 (the “Closing Date”), Artius Acquisition Inc. (“Artius”), a special purpose acquisition company, consummated the Merger Agreement and other Related Agreements (the “Merger Agreement”) dated February 16, 2021, by and among Artius, Zero Carbon Merger Sub Inc., a Delaware corporation and a wholly owned subsidiary of Artius (“Merger Sub”), and Micromidas, Inc. a Delaware corporation (now known as Origin Materials Operating Inc., ("Legacy Origin")). Pursuant to the terms of the Merger Agreement, a business combination between Artius and Legacy Origin was effected through the merger of Merger Sub with and into Legacy Origin, with Legacy Origin surviving as the surviving company and as a wholly-owned subsidiary of Artius (the “Merger” and, collectively with the other transactions described in the Merger Agreement, the “Business Combination”). On the Closing Date, Artius changed its name to Origin Materials, Inc. (collectively with its subsidiaries, the “Company”). For additional information on the Business Combination, please refer to Note 4, Business Combination, to these condensed consolidated financial statements.

PPP Loan	PPP LoanIn April 2020, the Company executed a promissory note (the “PPP Note”) evidencing an unsecured loan in the amount of $0.9 million under the Paycheck Protection Program (the “PPP Loan”). The Paycheck Protection Program (or “PPP”) was established under the Coronavirus Aid, Relief, and Economic Security Act (the “CARES Act”) and is administered by the U.S. Small Business Administration (“SBA”). The PPP Loan has been made through First Republic Bank (the “Lender”). The PPP Loan had a two-year term and bore interest at a rate of 1.00% per annum, accruing upon funding. Unless the PPP Loan is forgiven, the Company was required to make monthly payments of principal and interest to the Lender. The Company did not seek forgiveness of the PPP loan. The PPP Note contained customary events of default relating to, among other things, payment defaults, providing materially false and misleading representations to the SBA or Lender, or breaching the terms of the PPP Loan documents. The occurrence of an event of default may result in the immediate repayment of all amounts outstanding, collection of all amounts owing from the Company, or filing suit and obtaining judgment. Under the terms of the CARES Act, PPP Loan recipients can apply for and be granted forgiveness for all or a portion of the loan granted under the PPP. Such forgiveness will be determined, subject to limitations, based on the use of loan proceeds for payment of payroll costs and any payments of mortgage interest, rent, and utilities. The PPP Loan was paid in full during the year ended December 31, 2021.

Recent Accounting Pronouncements	3 Months Ended
Recent Accounting Pronouncements	Mar. 31, 2022
Recent Accounting Pronouncements [Abstract]
Recent Accounting Pronouncements	Recent Accounting Pronouncements Recently Adopted Accounting Pronouncements In August 2020, the FASB issued Accounting Standards Update ("ASU") 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. The guidance is effective for fiscal years beginning on or after December 15, 2021, with early adoption permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company adopted the new standard as of January 1, 2022. The adoption of the standard had no material impact. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended and supplemented by subsequent ASUs (collectively, “ASU 2020-04”), which provides practical expedients for contract modifications and certain hedging relationships associated with the transition from reference rates that are expected to be discontinued. This guidance is applicable for borrowing instruments, which use LIBOR as a reference rate, and is effective immediately, but is only available through December 31, 2022. The Company adopted the new standard as of January 1, 2022. The adoption of the standard had no material impact on the Company’s financial results. In November 2021, the FASB issued ASU 2021-10, Government Assistance ("Topic 832"), Disclosures by Business Entities about Government Assistance. The FASB issued this update to increase the transparency of government assistance including the disclosure of (1) the types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements. The main provisions of this update require the following disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy: (i) Information about the nature of the transactions and the related accounting policy used to account for the transactions (ii) The line items on the balance sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement line item (iii.) Significant terms and conditions of the transactions, including commitments and contingencies. The amendments in this update are effective for the Company in the annual period beginning after December 15, 2021. Early application of the amendments is permitted. The Company has elected to adopt on January 1, 2022. The adoption of the standard had no impact on the Company’s financial results. See Note 3 and Note 14 for required disclosures. Recently Issued Accounting Pronouncements Not Yet Adopted In October 2021, the FASB issued ASU 2021-08, Business Combinations ("Topic 805"), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This update improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to (1) recognition of an acquired contract liability; and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. Specifically, the update requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC Topic 606, Revenue from Contracts with Customers. The amendments in this update are effective for the Company in the fiscal year beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption of the amendments is permitted, including adoption in an interim period. The Company does not believe the adoption of this standard will have a material effect on its consolidated financial statements. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging ("Topic 815") ("ASU 2022-01"). This update clarifies the guidance in Topic 815 on fair value hedge accounting of interest rate risk for portfolios and financial assets. Among other things, the amended guidance established the “last-of-layer” method for making the fair value hedge accounting for these portfolios more accessible and renamed that method the “portfolio layer” method. ASU 2022-01 is effective January 1, 2023 and is not expected to have a significant impact on the Company's consolidated financial statements.

Leases [Abstract]
Leases	LeasesThe Company leases office space and research and development space in Sacramento, California and Sarnia, Ontario under noncancelable lease agreements and leases various office equipment, warehouse space, and temporary fencing. The operating leases have remaining lease terms of one to nine years. Certain operating leases contain options to extend the lease.

As such, lease terms for all leased assets located at the same locations have the same end dates. Rent deposits relating to leases are included within other long-term assets on the Condensed Consolidated Balance Sheets.

Earnout Liability	3 Months Ended
Earnout Liability	Mar. 31, 2022
Earnout Liability Disclosure [Abstract]
Earnout Liability	Earnout Liability As additional consideration for the Merger, within ten (10) Business Days after the occurrence of a Triggering Event, the Company shall issue or cause to be issued to each Legacy Origin and Artius stockholder the number of shares of the Company Class A Common Stock 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”). Notwithstanding anything to the contrary herein, in no event shall Artius be required to issue more than 25,000,000 Earnout Shares in the aggregate. A Triggering Event is defined as the following: (a)the volume weighted average price of Common Stock ("VWAP") equaling on exceeding $15.00 for ten (10) consecutive trading days during the three (3) year period following the Closing Date; (b)the VWAP equaling or exceeding $20.00 for ten (10) consecutive trading days during the four (4) year period following the Closing Date; or (c)the VWAP equaling or exceeding $25.00 for ten (10) consecutive trading days during the five (5) year period following the Closing Date. A Sponsor Letter Agreement was delivered in connection with the Merger such that 4,500,000 million of the shares held by Sponsor (“Sponsor Vesting Shares”) shall be subject forfeiture based on the same vesting requirements as the Earnout Shares. These shares shall not be transferred prior to the date in which they vest. Dividends and other distributions with respect to Sponsor Vesting Shares shall be set aside by the Company and shall be paid to the Sponsor upon the vesting of such Sponsor Vesting Shares. The Company evaluated the Earnout Liability under ASC 815-40, Derivatives and Hedging-Contracts in Entity’s Own Equity (“ASC 815-40”), and concluded they do not meet the criteria to be classified in stockholders’ equity. Specifically, there are contingent exercise provisions and settlement provisions that exist. Holders may receive differing amounts of shares depending on the company’s stock price or the price paid in a change of control. It is noted that 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 recorded these instruments as liabilities on the condensed consolidated balance sheet 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 63%, and interest rate of 0.87%. At March 31, 2022 and December 31, 2021 the balance of the earnout liability was $112.5 million and $127.8 million, respectively. A gain of $15.2 million was recorded in the three months ended March 31, 2022 Condensed Consolidated Statement of Operations and Comprehensive Income (Loss) for the change in the fair market value of the liability.

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”).

Pursuant to the Merger Agreement, the merger between Merger Sub and Legacy Origin was accounted for as a reverse recapitalization in accordance with U.S. GAAP (the “Reverse Recapitalization”). Under this method of accounting, Artius was treated as the “acquired” company and Legacy Origin is treated as the acquirer for financial reporting purposes.

Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Legacy Origin issuing stock for the net assets of Artius, accompanied by a recapitalization. The net assets of Artius are stated at historical cost, with no goodwill or other intangible assets recorded.

Legacy Origin was determined to be the accounting acquirer based on the following predominant factors:

•the Company’s Board of Directors (the “Board”) and management are primarily composed of individuals associated with Legacy Origin;

•Legacy Origin’s senior management comprise the senior management roles of the Company and are responsible for the day-to-day operations;

•the Company assumed the “doing business as” name of Legacy Origin; and

•The intended strategy and operations of the Company continue Legacy Origin’s current strategy and operations as a carbon negative materials company with a mission to enable the world’s transition to sustainable materials.

The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization are those of Legacy Origin. The shares and corresponding capital amounts and losses per share, prior to the Business Combination, have been retroactively restated based on shares reflecting the Exchange Ratio (as defined below) established in the Business Combination.

Use of Estimates

The preparation of the 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 expenses during the reporting periods. Estimates made by the Company include, but are not limited to, those related to the valuation of common stock and valuation of convertible preferred stock warrants prior to the Business Combination, valuation of the earnout liability, valuation of assumed common stock warrants liability, carrying amount and useful lives of property and equipment and intangible assets, impairment assessments, marketable securities, stock-based compensation expense, probabilities of achievement of performance conditions on performance stock 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 Interim Condensed Consolidated Financial Statements

The accompanying interim Condensed Consolidated Balance Sheet as of March 31, 2022, the interim Condensed Consolidated Statements of Operations and Comprehensive Income (Loss), the interim Condensed Consolidated Statements of Stockholders’ Equity and Accumulated Other Comprehensive Income (Loss), and the interim Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2022 and 2021, are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in management’s opinion, include all adjustments consisting of only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of March 31, 2022 and its results of operations and cash flows for the three months ended March 31, 2022 and 2021. The financial data and the other financial information disclosed in the notes to these condensed consolidated financial statements related to the three-month periods are also unaudited. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full fiscal year or any other period.

These unaudited interim 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, 2021 included the Company’s Form 10-K as filed with the SEC on March 1, 2022.

Principles of Consolidation

The unaudited interim 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, Origin Materials Canada Holding Limited, Origin Materials Canada Polyesters Limited, Origin Material Canada Pioneer Limited, Origin Materials Canada Research Limited, Origin Materials Operating, Inc, Origin US Megasite Holding, LLC, Origin US Megasite I, LLC, Origin US Megasite Development, LLC, and Origin US Megasite Operating, LLC. 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, and marketable securities. The Company maintains its cash, cash equivalents, and marketable securities accounts with a financial institution where, at times, deposits exceed federal insurance limits. Management believes that the Company is not exposed to significant credit risk as the Company’s deposits are held at financial institutions that management believes to be of high credit quality. The Company has not experienced any losses on these deposits.

Cash and Cash Equivalents and Restricted Cash

The Company considers all highly liquid investments with an initial maturity of three months or less at the date of purchase to be cash equivalents. The Company maintains such funds in cash deposits and money market accounts.

Restricted cash consists of cash held in a control account as collateral for the Company’s credit card services, escrow services, and standby letter of credit. These restricted cash balances have been excluded from cash and cash equivalents balance and are included within other current assets in the Condensed Consolidated Balance Sheets based on the respective maturity dates.

The Company entered into an escrow agreement on September 27, 2019 for $1.3 million, whereby the funds would be used for construction and transportation services in connection with Origin 1. At March 31, 2022 and December 31, 2021, the escrow account had a balance of $0.3 million.

The Company has a standby letter of credit, whereby the funds may be used for the completion of work, services, and improvements in connection with Origin 1. The standby letter of credit matures and automatically renews in October of each year. At March 31, 2022 and December 31, 2021, the standby letter of credit was $0.2 million.

Cash, cash equivalents, and restricted cash consisted of the following (in thousands):


	March 31, 2022		December 31, 2021
Cash and cash equivalents	$	57,941	$	46,637
Restricted cash	$	490	$	490
Total cash, cash equivalents, and restricted cash	$	58,431	$	47,127

Marketable Securities

The Company’s investment policy is consistent with the definition of available-for-sale securities. The Company does not buy and hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity, and return. The Company considers all of its marketable debt securities as available for use in current operations, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the consolidated balance sheets. Securities are classified as available for sale and are carried at fair value, with the change in unrealized gains and losses, net of tax, reported as a separate component on the consolidated statements of comprehensive income until realized. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. Securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of the excess, if any, is caused by expected credit losses. Expected credit losses on securities are recognized in other income (expense), net on the consolidated statements of operations and comprehensive loss, and any remaining unrealized losses, net of taxes, are included in accumulated other comprehensive loss in the consolidated statement of stockholders' equity. For the purposes of computing realized and unrealized gains and losses, the cost of securities sold is based on the specific-identification method. Interest on securities classified as available for sale is included as a component of interest income within other income (expense).

The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include agency mortgage-backed securities, corporate fixed income securities infrequently traded, and other securities, which primarily consist of sovereign debt, U.S. government agency securities, loans, and state and municipal securities.

Derivative Financial Instruments

The Company evaluated the stockholder convertible notes payable in accordance with ASC 815, Derivatives and Hedging and determined that the embedded components of these contracts qualify as a derivative to be separately accounted for as a liability. The Company records the fair value of the embedded components in accordance with ASC 815, Derivatives and Hedging. The fair value of the derivatives was calculated using a model that estimated the value that would be paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value of the derivative liabilities is revalued on each balance sheet date with a corresponding gain or loss recorded in the Consolidated Statements of Operations and Comprehensive Income (Loss).

The Company enters into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk related to marketable securities. The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in the British Pound Sterling and Australian Dollar. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with marketable securities. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. Outstanding foreign currency derivative contracts are recorded at fair value on the consolidated balance sheets.

Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized in the change in fair value of derivatives within other (income) expense. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties. The notional amount of foreign currency derivative contracts as of March 31, 2022 and December 31, 2021 was $29.2 million and $63.7 million, respectively.

Fair Value of Financial Instruments

The Company applies the fair value measurement accounting standard whenever other accounting pronouncements require or permit fair value measurements. Fair value is defined in the accounting standard as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy under current accounting guidance prioritizes the inputs to valuation techniques used to measure fair value into three broad levels (Level 1, Level 2, and Level 3).

Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability and reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk) in a principal market.

The carrying amounts of working capital balances approximate their fair values due to the short maturity of these items. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest rate, currency, or credit risks arising from its financial instruments. The fair value of debt approximates its carrying value based on prevailing market rates.

The fair values of the assumed common stock warrants which are publicly traded are level 1 inputs. The fair value of the assumed common stock warrants which are not publicly traded, cash equivalents, marketable securities, and foreign currency derivative contracts are level 2 inputs as the Company uses quoted market prices or alternative pricing sources and models utilizing observable market inputs. The earnout liability, derivative liability and redeemable convertible preferred stock warrant liability were estimated using Level 3 inputs.

Other Receivables

Other receivables consist of amounts due from foreign governmental entities related to the Canadian harmonized sales tax (HST) and goods and services tax (GST) for goods and services transacted in Canada, and amounts due from cash collateral held by others for foreign currency derivative contracts.

AgriScience Grant

In January 2019, the Company entered into an agreement in which it will participate in the AgriScience Program Cluster Component grant through the Canadian Agricultural Partnership, whereby the Company will receive reimbursements for eligible expenditures up to approximately $2.7 million (in Canadian dollars) through March 2022. Grants are received through reimbursements from the Canadian government and recognized, upon completion of scope of services on a quarterly basis. Grants are recognized as a reduction of property, plant, and equipment or expense based on the nature of the cost the grant is reimbursing. During the three months ended March 31, 2022 and 2021 the Company received $0.0 million in grants, recorded in other income.

Property, Plant, and Equipment

Property, plant, and equipment are recorded at cost and depreciated or amortized using the straight-line method over the estimated useful lives of the respective assets. Existing useful lives range from three to five years. Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or the lease term. Major additions and improvements are capitalized, while replacements, repairs, and maintenance that do not extend the life of an asset are charged to operations. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation or amortization are removed from the accounts. Costs incurred to acquire, construct or install property, plant, and equipment during the construction stage of a capital project and costs capitalized in conjunction with major improvements that have not yet been placed in service are recorded as construction in progress, and accordingly are not

currently being depreciated. The Company capitalizes interest cost incurred on funds used to construct property, plant and equipment. The estimated useful lives of assets are as follows:


Computer Equipment			3 years
Office Furniture			5 years
Machinery and Equipment			5 years
Leasehold Improvements			1-5 years

Intangible Assets

Intangible assets are recorded at cost and are amortized using the straight-line method over the estimated useful lives of the respective assets, ranging from 7 to 15 years. The cost of servicing the Company’s patents is expensed as incurred. Upon retirement or sale, the cost of intangible assets is disposed of and the related accumulated amortization is removed from the accounts.

Impairment of Long-Lived Assets

The Company reviews its long-lived assets, including property, equipment, software and intangibles, 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. If the total of the expected undiscounted future net cash flows for the asset group is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and carrying amount of the asset. For the three month period ended March 31, 2022 and 2021, no impairment was identified.

Government Loans

Government loans are classified as a noncurrent liability and recorded at amortized cost. Forgiveness of the balances due is recorded through earnings and occurs when there is confirmation from the governmental authority that the Company has complied with the conditions for forgiveness attached to the loan.

Debt Issuance Costs

The costs incurred in connection with the issuance of debt obligations, principally financing and legal costs, are capitalized. These costs are accreted over the term of the debt using the interest method. During the three months ended March 31, 2022 and 2021, accretion expense for debt issuance cost were immaterial.

Redeemable Convertible Preferred Stock Warrants Liability

Free-standing warrants issued by Legacy Origin for the purchase of shares of its convertible preferred stock were classified as liabilities on the accompanying balance sheets at fair value using an Option-Pricing Model. Prior to the Business Combination, the liability recorded was adjusted for changes in the fair value at each reporting date and recorded as interest expense in the accompanying unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As a result of the Business Combination, the Legacy Origin warrants each converted into a warrant to purchase shares of the Company’s Common Stock converted at the Exchange Ratio. The fair value of the warrants upon consummation of the Business Combination (see Note 4), is adjusted based on the price of the underlying Common Stock, was reclassified to additional paid-in capital.

Assumed Common Stock Warrants Liability

The Company assumed 24,150,000 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 “Assumed Common Stock Warrants”) upon the Business Combination, all of which were issued in connection with Artius’ initial public offering and entitle each holder to purchase one share of Class A Common Stock at an exercise price of at $11.50 per share. As of March 31, 2022, 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 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.

The Company evaluated the Assumed 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 Assumed Common Stock Warrants may be settled in cash upon the occurrence of a tender offer or exchange that involves 50% or more of our Class A stockholders. Because not all of the voting stockholders need to participate in such tender offer or exchange to trigger the potential cash settlement and the Company does not control the occurrence of such an event, the Company concluded that the Assumed Common Stock Warrants do not meet the conditions to be classified in equity. Since the Assumed Common Stock Warrants meet the definition of a derivative under ASC 815, the Company recorded these warrants as liabilities on the Condensed Consolidated Balance Sheets at fair value, with subsequent changes in their respective fair values recognized in the change in fair value of Assumed Common Stock Warrant liabilities within the Condensed Consolidated Statements of Operations and Comprehensive Income (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 6.

Earnout Liability

The Company has recorded an earnout liability related to future contingent equity shares related to the Business Combination (Note 13). The Company recorded these instruments as liabilities on the Condensed Consolidated Balance Sheet at fair value, with subsequent changes in their respective fair values recognized in earnings at each reporting date.

Leases

The Company has operating leases for office space and equipment, some of which have escalating rentals during the initial lease term and during subsequent optional renewal periods. The Company accounts for its leases under ASC 842, Leases. The Company recognizes a right-of-use asset and lease liability for operating leases based on the net present value of future minimum lease payments. Lease expense is recognized on a straight-line basis over the non-cancelable lease term and renewal periods that are considered reasonably certain.

Research and Development Cost

Costs related to research and development are expensed as incurred.

Stock-Based Compensation

The Company has issued common stock awards under three equity incentive plans. Origin measures stock options and other stock-based awards granted to employees, directors and other service providers based on their fair value on the date of grant and recognizes compensation expenses of those awards over the requisite service period, which is generally the vesting period of the respective award. For awards with performance conditions, compensation is recorded once there is sufficient objective evidence the performance conditions are considered probable of being met. Origin applies the straight-line method of expense recognition to all awards with only service-based vesting conditions. Origin estimates the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model and the grant date closing stock price for RSU awards and performance awards. The Black-Scholes option-pricing model requires the use of highly subjective assumptions including:

•Expected term – The expected term of the options is based on the simplified method, which takes into consideration the grant’s contractual life and vesting period and assumes that all options will be exercised between the vesting date and the contractual term of the option which averages an award’s vesting term and its contractual term.

•Expected volatility – The Company uses the trading history of various companies in its industry sector in determining an estimated volatility factor.

•Expected dividend – The Company has not declared common stock dividends and does not anticipate declaring any common stock dividends in the foreseeable future.

•Forfeiture – The Company estimates forfeitures based on historical activity and considers voluntary and involuntary termination behavior as well as analysis of actual historical option forfeitures, netting the estimated expense by the derived forfeiture rate.

•Risk-free interest rate – The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with the same or substantially equivalent remaining term.

Income Taxes

Deferred income taxes are determined using the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when the expected recognition of a deferred income tax asset is considered to be unlikely.

The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters as a component of income tax expense.

Functional Currency Translation

The functional currency of the Company’s wholly-owned subsidiaries is the Canadian dollar, whereby their assets and liabilities are translated at period-end exchange rates except for nonmonetary capital transactions and balances, which are translated at historical rates. All income and expense amounts of the Company are translated at average exchange rates for the respective period. Translation gains and losses are not included in determining net loss but are accumulated in a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in the determination of net loss in the period in which they occur. These amounts are included in other income, net, of the unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).

Comprehensive Income (Loss)

The Company’s comprehensive income or loss consists of net income or loss and other comprehensive income (loss). Foreign currency translation gains or losses and unrealized gains or losses on available-for-sale marketable debt securities are included in the Company’s other comprehensive income (loss).

Basic and Diluted Net Income (Loss) Per Share

Basic net income (loss) per common share is calculated by dividing the net income (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 income (loss) per share is computed by dividing the net income (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 income (loss) per share calculation, the convertible preferred stock, common stock options, RSU awards, performance stock awards, convertible preferred stock warrants, common stock warrants, convertible notes, earnout shares, and Sponsor Vesting Shares (as defined below) are considered to be potentially dilutive securities. Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The two-class method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. All series of the Company’s convertible preferred stock are considered to be participating securities because, in addition to cumulative dividends, all holders are entitled to receive a non-cumulative dividend on a pari passu basis in the event that a dividend is paid on the common stock. The two-class method requires income or loss available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to share in undistributed earnings as if all income or loss for the period had been distributed. The holders of the convertible preferred stock do not have a contractual obligation to share in the Company’s losses. Accordingly, the Company’s net income (loss) is attributed entirely to common stockholders. 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.

Reclassifications

Certain amounts in prior periods have been reclassified to conform with the report classifications of the three months ended March 31, 2022, noting the Company has reflected the reverse recapitalization pursuant to the Business Combination as of and for the three months ended March 31, 2021, within the unaudited condensed financial statements.

Segment Reporting

The Company operates in a single segment. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing performance. The Company has determined that its Co-Chief Executive Officers are the CODM. To date, the Company’s CODM has made such decisions and assessed performance at the Company level.

As of March 31, 2022 and December 31, 2021, the Company had $73.8 million and $60.6 million, respectively, of assets located outside of the United States.

Assumed Common Stock Warrants [Abstract]
Assumed Common Stock Warrants	Assumed Common Stock Warrants As of March 31, 2022 there are 35,476,627 warrants outstanding. As part of Artius’s initial public offering, 24,150,000 Public Warrants were sold. The Public Warrants entitle the holder thereof to purchase one share of Common Stock at a price of $11.50 per share, subject to adjustments. The Public Warrants may be exercised only for a whole number of shares of Common Stock. No fractional shares will be issued upon exercise of the warrants. The Public Warrants will expire on June 25, 2026 at 5:00p.m., New York City time, or earlier upon redemption or liquidation. The Public Warrants are listed on the Nasdaq under the symbol “ORGNW”. The Company may redeem the Public Warrants when exercisable, in whole and not in part, at a price of $0.01 per warrant, so long as the Company provides not less than 30 days’ prior written notice of redemption to each warrant holder, and if, and only if, the reported last sale price of the Common Stock equals or exceeds $18.00 per share for any 20 trading days within a 30-trading day period ending on the third trading day prior to the date the Company sends the notice of redemption to the warrant holders. Simultaneously with Artius’s initial public offering, Artius consummated a private placement of 11,326,667 Private Placement Warrants with the Sponsor. The Private Placement Warrant is exercisable for one share of Class A Common Stock at a price of $11.50 per share, subject to adjustment. The Private Placement Warrants are identical to the Public Warrants, except that: (1) the Private Placement Warrants and the shares of Class A Common Stock issuable upon exercise of the Private Placement Warrants are not transferable, assignable or salable until the earliest to occur of: (i) 365 days after the date of the Closing; (ii) the first day after the date on which the closing price of the Public Shares (or any successor securities thereto) equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the date of the Closing; or (iii) the date on which Artius completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of Artius’s Public Shareholders having the right to exchange their Public Shares (or any successor securities thereto) for cash, securities or other property, subject to certain limited exceptions, (2) the Private Placement Warrants will be exercisable on a cashless basis and be non-redeemable, except if the reference value equals or exceeds $10.00 and is less than $18.00 (as described above), so long as they are held by the initial purchasers or their permitted transferees, and (3) the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will be entitled to registration rights. If the Private Placement Warrants are held by someone other than the initial purchasers or their permitted transferees, the Private Placement Warrants will be redeemable under all redemption scenarios by the Company and exercisable by such holders on the same basis as the Public Warrants. The Company concluded the Public Warrants and Private Placement Warrants, or Assumed Common Stock Warrants, meet the definition of a derivative under ASC 815 and are recorded as liabilities. Upon consummation of the Business Combination, the fair value of the Assumed Common Stock Warrants was recorded on the Condensed Consolidated Balance Sheet. The fair value of the Assumed Common Stock Warrants was remeasured on the March 31, 2022 and December 31, 2021 Condensed Consolidated Balance Sheets at $54.6 million and $52.9 million, respectively, with a loss of $1.8 million recorded in the three months ended March 31, 2022 Condensed Consolidated Statement of Operations and Comprehensive Income (Loss).

Risks and Liquidity	Mar. 31, 2022
Risks And Liquidity [Abstract]
Risks and Liquidity	Risks and Liquidity Prior to the Business Combination, the Company primarily financed its operations through the sale of convertible preferred stock, common stock, borrowings under convertible promissory notes and borrowings under loan agreements. The Company now believes that the Business Combination has provided substantial liquidity and that its $427.7 million of cash and cash equivalents, restricted cash, and marketable securities will enable it to fund its planned operations for at least twelve months from the issuance date of these condensed consolidated financial statements. Beginning in March 2020, the COVID-19 pandemic and the measures imposed to contain this pandemic have disrupted and are expected to continue to impact the Company’s business. The magnitude of the impact of the COVID-19 pandemic on the Company’s productivity, results of operations and financial position, and its disruption to the Company’s business and timeline, will depend in part, on the length and severity of these restrictions and on the Company’s ability to conduct business in the ordinary course. We continue to monitor the rapidly evolving conditions and circumstances, as well as guidance from international and domestic authorities, including public health authorities, and we may need to take additional actions based on their recommendations. There is considerable uncertainty regarding the impact on our business stemming from current measures and potential future measures that could restrict access to our facilities, limit manufacturing and support operations and place restrictions on our workforce and suppliers. The measures implemented by various authorities related to the COVID-19 outbreak have caused us to change our business practices including those related to where employees work, the distance between employees in our facilities, limitations on in-person meetings between employees and with customers, suppliers, service providers and stakeholders, as well as restrictions on business travel to domestic and international locations or to attend trade shows, investor conferences and other events. In February 2022, Russia began a military intervention in Ukraine. In response, global sanctions were imposed against Russia. These sanctions and the global ramifications could impact the costs and timing of construction of the Origin 1 and Origin 2 plants.

Summary of Significant Accounting Policies (Policies)	Mar. 31, 2022
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”). Pursuant to the Merger Agreement, the merger between Merger Sub and Legacy Origin was accounted for as a reverse recapitalization in accordance with U.S. GAAP (the “Reverse Recapitalization”). Under this method of accounting, Artius was treated as the “acquired” company and Legacy Origin is treated as the acquirer for financial reporting purposes. Accordingly, for accounting purposes, the Reverse Recapitalization was treated as the equivalent of Legacy Origin issuing stock for the net assets of Artius, accompanied by a recapitalization. The net assets of Artius are stated at historical cost, with no goodwill or other intangible assets recorded. Legacy Origin was determined to be the accounting acquirer based on the following predominant factors: •the Company’s Board of Directors (the “Board”) and management are primarily composed of individuals associated with Legacy Origin; •Legacy Origin’s senior management comprise the senior management roles of the Company and are responsible for the day-to-day operations; •the Company assumed the “doing business as” name of Legacy Origin; and •The intended strategy and operations of the Company continue Legacy Origin’s current strategy and operations as a carbon negative materials company with a mission to enable the world’s transition to sustainable materials. The consolidated assets, liabilities and results of operations prior to the Reverse Recapitalization are those of Legacy Origin. The shares and corresponding capital amounts and losses per share, prior to the Business Combination, have been retroactively restated based on shares reflecting the Exchange Ratio (as defined below) established in the Business Combination.
Use of Estimates	Use of Estimates The preparation of the 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 expenses during the reporting periods. Estimates made by the Company include, but are not limited to, those related to the valuation of common stock and valuation of convertible preferred stock warrants prior to the Business Combination, valuation of the earnout liability, valuation of assumed common stock warrants liability, carrying amount and useful lives of property and equipment and intangible assets, impairment assessments, marketable securities, stock-based compensation expense, probabilities of achievement of performance conditions on performance stock 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 Interim Condensed Consolidated Financial Statements	Unaudited Interim Condensed Consolidated Financial Statements The accompanying interim Condensed Consolidated Balance Sheet as of March 31, 2022, the interim Condensed Consolidated Statements of Operations and Comprehensive Income (Loss), the interim Condensed Consolidated Statements of Stockholders’ Equity and Accumulated Other Comprehensive Income (Loss), and the interim Condensed Consolidated Statements of Cash Flows for the three months ended March 31, 2022 and 2021, are unaudited. The unaudited interim condensed consolidated financial statements have been prepared on the same basis as the audited annual consolidated financial statements and, in management’s opinion, include all adjustments consisting of only normal recurring adjustments necessary for the fair statement of the Company’s financial position as of March 31, 2022 and its results of operations and cash flows for the three months ended March 31, 2022 and 2021. The financial data and the other financial information disclosed in the notes to these condensed consolidated financial statements related to the three-month periods are also unaudited. The results of operations for the three months ended March 31, 2022 are not necessarily indicative of the results to be expected for the full fiscal year or any other period. These unaudited interim 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, 2021 included the Company’s Form 10-K as filed with the SEC on March 1, 2022.
Principles of Consolidation	Principles of Consolidation The unaudited interim 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, Origin Materials Canada Holding Limited, Origin Materials Canada Polyesters Limited, Origin Material Canada Pioneer Limited, Origin Materials Canada Research Limited, Origin Materials Operating, Inc, Origin US Megasite Holding, LLC, Origin US Megasite I, LLC, Origin US Megasite Development, LLC, and Origin US Megasite Operating, LLC. 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, and marketable securities. The Company maintains its cash, cash equivalents, and marketable securities accounts with a financial institution where, at times, deposits exceed federal insurance limits. Management believes that the Company is not exposed to significant credit risk as the Company’s deposits are held at financial institutions that management believes to be of high credit quality. The Company has not experienced any losses on these deposits.
Cash and Cash Equivalents and Restricted Cash	Cash and Cash Equivalents and Restricted Cash The Company considers all highly liquid investments with an initial maturity of three months or less at the date of purchase to be cash equivalents. The Company maintains such funds in cash deposits and money market accounts. Restricted cash consists of cash held in a control account as collateral for the Company’s credit card services, escrow services, and standby letter of credit. These restricted cash balances have been excluded from cash and cash equivalents balance and are included within other current assets in the Condensed Consolidated Balance Sheets based on the respective maturity dates.
Marketable Securities	Marketable Securities The Company’s investment policy is consistent with the definition of available-for-sale securities. The Company does not buy and hold securities principally for the purpose of selling them in the near future. The Company’s policy is focused on the preservation of capital, liquidity, and return. The Company considers all of its marketable debt securities as available for use in current operations, including those with maturity dates beyond one year, and therefore classifies these securities within current assets on the consolidated balance sheets. Securities are classified as available for sale and are carried at fair value, with the change in unrealized gains and losses, net of tax, reported as a separate component on the consolidated statements of comprehensive income until realized. Fair value is determined based on quoted market rates when observable or utilizing data points that are observable, such as quoted prices, interest rates and yield curves. Securities with an amortized cost basis in excess of estimated fair value are assessed to determine what amount of the excess, if any, is caused by expected credit losses. Expected credit losses on securities are recognized in other income (expense), net on the consolidated statements of operations and comprehensive loss, and any remaining unrealized losses, net of taxes, are included in accumulated other comprehensive loss in the consolidated statement of stockholders' equity. For the purposes of computing realized and unrealized gains and losses, the cost of securities sold is based on the specific-identification method. Interest on securities classified as available for sale is included as a component of interest income within other income (expense). The nature of these financial instruments include instruments for which quoted prices are available but traded less frequently, instruments whose fair value has been derived using a model where inputs to the model are directly observable in the market, or can be derived principally from or corroborated by observable market data, and instruments that are fair valued using other financial instruments, the parameters of which can be directly observed. Level 2 financial instruments include agency mortgage-backed securities, corporate fixed income securities infrequently traded, and other securities, which primarily consist of sovereign debt, U.S. government agency securities, loans, and state and municipal securities.
Derivative Financial Instruments	Derivative Financial Instruments The Company evaluated the stockholder convertible notes payable in accordance with ASC 815, Derivatives and Hedging and determined that the embedded components of these contracts qualify as a derivative to be separately accounted for as a liability. The Company records the fair value of the embedded components in accordance with ASC 815, Derivatives and Hedging. The fair value of the derivatives was calculated using a model that estimated the value that would be paid to transfer the liability in an orderly transaction between market participants at the measurement date. The fair value of the derivative liabilities is revalued on each balance sheet date with a corresponding gain or loss recorded in the Consolidated Statements of Operations and Comprehensive Income (Loss). The Company enters into foreign currency derivative contracts with financial institutions to reduce foreign exchange risk related to marketable securities. The Company uses forward currency derivative contracts to minimize the Company’s exposure to balances primarily denominated in the British Pound Sterling and Australian Dollar. The Company’s foreign currency derivative contracts, which are not designated as hedging instruments, are used to reduce the exchange rate risk associated primarily with marketable securities. The Company’s derivative financial instruments program is not designated for trading or speculative purposes. Outstanding foreign currency derivative contracts are recorded at fair value on the consolidated balance sheets. Foreign currency derivative contracts are marked-to-market at the end of each reporting period with gains and losses recognized in the change in fair value of derivatives within other (income) expense. While the contract or notional amount is often used to express the volume of foreign currency derivative contracts, the amounts potentially subject to credit risk are generally limited to the amounts, if any, by which the counterparties’ obligations under the agreements exceed the obligations of the Company to the counterparties.
Fair Value of Financial Instruments	Fair Value of Financial Instruments The Company applies the fair value measurement accounting standard whenever other accounting pronouncements require or permit fair value measurements. Fair value is defined in the accounting standard as the price that would be received to sell an asset or paid to transfer a liability in an orderly transaction between market participants at the measurement date. The fair value hierarchy under current accounting guidance prioritizes the inputs to valuation techniques used to measure fair value into three broad levels (Level 1, Level 2, and Level 3). Level 1 inputs are unadjusted quoted prices in active markets for identical assets or liabilities that the Company has the ability to access at the measurement date. Level 2 inputs are inputs other than quoted prices included within Level 1 that are observable for the asset or liability, either directly or indirectly. Level 3 inputs are unobservable inputs for the asset or liability and reflect the Company’s own assumptions about the assumptions that market participants would use in pricing the asset or liability (including assumptions about risk) in a principal market. The carrying amounts of working capital balances approximate their fair values due to the short maturity of these items. Unless otherwise noted, it is management’s opinion that the Company is not exposed to significant interest rate, currency, or credit risks arising from its financial instruments. The fair value of debt approximates its carrying value based on prevailing market rates. The fair values of the assumed common stock warrants which are publicly traded are level 1 inputs. The fair value of the assumed common stock warrants which are not publicly traded, cash equivalents, marketable securities, and foreign currency derivative contracts are level 2 inputs as the Company uses quoted market prices or alternative pricing sources and models utilizing observable market inputs. The earnout liability, derivative liability and redeemable convertible preferred stock warrant liability were estimated using Level 3 inputs.
Other Receivables	Other Receivables Other receivables consist of amounts due from foreign governmental entities related to the Canadian harmonized sales tax (HST) and goods and services tax (GST) for goods and services transacted in Canada, and amounts due from cash collateral held by others for foreign currency derivative contracts.
AgriScience Grant	AgriScience Grant In January 2019, the Company entered into an agreement in which it will participate in the AgriScience Program Cluster Component grant through the Canadian Agricultural Partnership, whereby the Company will receive reimbursements for eligible expenditures up to approximately $2.7 million (in Canadian dollars) through March 2022. Grants are received through reimbursements from the Canadian government and recognized, upon completion of scope of services on a quarterly basis. Grants are recognized as a reduction of property, plant, and equipment or expense based on the nature of the cost the grant is reimbursing.
Property, Plant, and Equipment	Property, Plant, and Equipment Property, plant, and equipment are recorded at cost and depreciated or amortized using the straight-line method over the estimated useful lives of the respective assets. Existing useful lives range from three to five years. Leasehold improvements are amortized using the straight-line method over the shorter of their estimated useful lives or the lease term. Major additions and improvements are capitalized, while replacements, repairs, and maintenance that do not extend the life of an asset are charged to operations. Upon retirement or sale, the cost of assets disposed of and the related accumulated depreciation or amortization are removed from the accounts. Costs incurred to acquire, construct or install property, plant, and equipment during the construction stage of a capital project and costs capitalized in conjunction with major improvements that have not yet been placed in service are recorded as construction in progress, and accordingly are not currently being depreciated. The Company capitalizes interest cost incurred on funds used to construct property, plant and equipment.
Intangible Assets	Intangible Assets Intangible assets are recorded at cost and are amortized using the straight-line method over the estimated useful lives of the respective assets, ranging from 7 to 15 years. The cost of servicing the Company’s patents is expensed as incurred. Upon retirement or sale, the cost of intangible assets is disposed of and the related accumulated amortization is removed from the accounts.
Impairment of Long-Lived Assets	Impairment of Long-Lived Assets The Company reviews its long-lived assets, including property, equipment, software and intangibles, 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. If the total of the expected undiscounted future net cash flows for the asset group is less than the carrying amount of the asset, a loss is recognized for the difference between the fair value and carrying amount of the asset.
Government Loans	Government Loans Government loans are classified as a noncurrent liability and recorded at amortized cost. Forgiveness of the balances due is recorded through earnings and occurs when there is confirmation from the governmental authority that the Company has complied with the conditions for forgiveness attached to the loan.
Debt Issuance Costs	Debt Issuance Costs The costs incurred in connection with the issuance of debt obligations, principally financing and legal costs, are capitalized. These costs are accreted over the term of the debt using the interest method.
Redeemable Convertible Preferred Stock Warrants Liability	Redeemable Convertible Preferred Stock Warrants Liability Free-standing warrants issued by Legacy Origin for the purchase of shares of its convertible preferred stock were classified as liabilities on the accompanying balance sheets at fair value using an Option-Pricing Model. Prior to the Business Combination, the liability recorded was adjusted for changes in the fair value at each reporting date and recorded as interest expense in the accompanying unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss). As a result of the Business Combination, the Legacy Origin warrants each converted into a warrant to purchase shares of the Company’s Common Stock converted at the Exchange Ratio. The fair value of the warrants upon consummation of the Business Combination (see Note 4), is adjusted based on the price of the underlying Common Stock, was reclassified to additional paid-in capital.
Assumed Common Stock Warrants Liability	Assumed Common Stock Warrants Liability The Company assumed 24,150,000 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 “Assumed Common Stock Warrants”) upon the Business Combination, all of which were issued in connection with Artius’ initial public offering and entitle each holder to purchase one share of Class A Common Stock at an exercise price of at $11.50 per share. As of March 31, 2022, 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 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. The Company evaluated the Assumed 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 Assumed Common Stock Warrants may be settled in cash upon the occurrence of a tender offer or exchange that involves 50% or more of our Class A stockholders. Because not all of the voting stockholders need to participate in such tender offer or exchange to trigger the potential cash settlement and the Company does not control the occurrence of such an event, the Company concluded that the Assumed Common Stock Warrants do not meet the conditions to be classified in equity. Since the Assumed Common Stock Warrants meet the definition of a derivative under ASC 815, the Company recorded these warrants as liabilities on the Condensed Consolidated Balance Sheets at fair value, with subsequent changes in their respective fair values recognized in the change in fair value of Assumed Common Stock Warrant liabilities within the Condensed Consolidated Statements of Operations and Comprehensive Income (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 6.
Earnout Liability	Earnout Liability The Company has recorded an earnout liability related to future contingent equity shares related to the Business Combination (Note 13). The Company recorded these instruments as liabilities on the Condensed Consolidated Balance Sheet at fair value, with subsequent changes in their respective fair values recognized in earnings at each reporting date.
Leases	Leases The Company has operating leases for office space and equipment, some of which have escalating rentals during the initial lease term and during subsequent optional renewal periods. The Company accounts for its leases under ASC 842, Leases. The Company recognizes a right-of-use asset and lease liability for operating leases based on the net present value of future minimum lease payments. Lease expense is recognized on a straight-line basis over the non-cancelable lease term and renewal periods that are considered reasonably certain.
Research and Development Cost	Research and Development Cost Costs related to research and development are expensed as incurred.
Stock-Based Compensation	Stock-Based Compensation The Company has issued common stock awards under three equity incentive plans. Origin measures stock options and other stock-based awards granted to employees, directors and other service providers based on their fair value on the date of grant and recognizes compensation expenses of those awards over the requisite service period, which is generally the vesting period of the respective award. For awards with performance conditions, compensation is recorded once there is sufficient objective evidence the performance conditions are considered probable of being met. Origin applies the straight-line method of expense recognition to all awards with only service-based vesting conditions. Origin estimates the fair value of each stock option grant on the date of grant using the Black-Scholes option-pricing model and the grant date closing stock price for RSU awards and performance awards. The Black-Scholes option-pricing model requires the use of highly subjective assumptions including: •Expected term – The expected term of the options is based on the simplified method, which takes into consideration the grant’s contractual life and vesting period and assumes that all options will be exercised between the vesting date and the contractual term of the option which averages an award’s vesting term and its contractual term. •Expected volatility – The Company uses the trading history of various companies in its industry sector in determining an estimated volatility factor. •Expected dividend – The Company has not declared common stock dividends and does not anticipate declaring any common stock dividends in the foreseeable future. •Forfeiture – The Company estimates forfeitures based on historical activity and considers voluntary and involuntary termination behavior as well as analysis of actual historical option forfeitures, netting the estimated expense by the derived forfeiture rate. •Risk-free interest rate – The Company bases the risk-free interest rate on the implied yield currently available on U.S. Treasury zero-coupon issues with the same or substantially equivalent remaining term.
Income Taxes	Income Taxes Deferred income taxes are determined using the asset and liability method. Under this method, deferred income tax assets and liabilities are determined based on differences between the financial reporting and tax bases of assets and liabilities and are measured using the enacted tax rates and laws that will be in effect when the differences are expected to reverse. A valuation allowance is recorded when the expected recognition of a deferred income tax asset is considered to be unlikely. The Company recognizes the tax benefit from an uncertain tax position only if it is more likely than not that the tax position will be sustained on examination by the tax authorities, based on the technical merits of the position. The tax benefit is measured based on the largest benefit that has a greater than 50% likelihood of being realized upon ultimate settlement. The Company recognizes interest and penalties related to income tax matters as a component of income tax expense.
Functional Currency Translation	Functional Currency Translation The functional currency of the Company’s wholly-owned subsidiaries is the Canadian dollar, whereby their assets and liabilities are translated at period-end exchange rates except for nonmonetary capital transactions and balances, which are translated at historical rates. All income and expense amounts of the Company are translated at average exchange rates for the respective period. Translation gains and losses are not included in determining net loss but are accumulated in a separate component of stockholders’ equity. Foreign currency transaction gains and losses are included in the determination of net loss in the period in which they occur. These amounts are included in other income, net, of the unaudited Condensed Consolidated Statements of Operations and Comprehensive Income (Loss).
Comprehensive Income (Loss)	Comprehensive Income (Loss) The Company’s comprehensive income or loss consists of net income or loss and other comprehensive income (loss). Foreign currency translation gains or losses and unrealized gains or losses on available-for-sale marketable debt securities are included in the Company’s other comprehensive income (loss).
Basic and Diluted Net Income (Loss) Per Share	Basic and Diluted Net Income (Loss) Per Share Basic net income (loss) per common share is calculated by dividing the net income (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 income (loss) per share is computed by dividing the net income (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 income (loss) per share calculation, the convertible preferred stock, common stock options, RSU awards, performance stock awards, convertible preferred stock warrants, common stock warrants, convertible notes, earnout shares, and Sponsor Vesting Shares (as defined below) are considered to be potentially dilutive securities. Basic and diluted net income (loss) per share attributable to common stockholders is presented in conformity with the two-class method required for participating securities. The two-class method determines net income (loss) per share for each class of common and participating securities according to dividends declared or accumulated and participation rights in undistributed earnings. All series of the Company’s convertible preferred stock are considered to be participating securities because, in addition to cumulative dividends, all holders are entitled to receive a non-cumulative dividend on a pari passu basis in the event that a dividend is paid on the common stock. The two-class method requires income or loss available to common stockholders for the period to be allocated between common and participating securities based upon their respective rights to share in undistributed earnings as if all income or loss for the period had been distributed. The holders of the convertible preferred stock do not have a contractual obligation to share in the Company’s losses. Accordingly, the Company’s net income (loss) is attributed entirely to common stockholders. 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.
Reclassifications	Reclassifications Certain amounts in prior periods have been reclassified to conform with the report classifications of the three months ended March 31, 2022, noting the Company has reflected the reverse recapitalization pursuant to the Business Combination as of and for the three months ended March 31, 2021, within the unaudited condensed financial statements.
Segment Reporting	Segment Reporting The Company operates in a single segment. Operating segments are identified as components of an enterprise about which separate discrete financial information is available for evaluation by the chief operating decision maker (“CODM”) in making decisions regarding resource allocation and assessing performance. The Company has determined that its Co-Chief Executive Officers are the CODM. To date, the Company’s CODM has made such decisions and assessed performance at the Company level.
Recently Adopted Accounting Pronouncements and Recently Issued Accounting Pronouncements Not Yet Adopted	Recently Adopted Accounting Pronouncements In August 2020, the FASB issued Accounting Standards Update ("ASU") 2020-06, Accounting for Convertible Instruments and Contracts in an Entity’s Own Equity, which simplifies the accounting for certain financial instruments with characteristics of liabilities and equity, including convertible instruments and contracts in an entity’s own equity. The guidance is effective for fiscal years beginning on or after December 15, 2021, with early adoption permitted, but no earlier than fiscal years beginning after December 15, 2020. The Company adopted the new standard as of January 1, 2022. The adoption of the standard had no material impact. In March 2020, the FASB issued ASU 2020-04, Reference Rate Reform ("Topic 848"): Facilitation of the Effects of Reference Rate Reform on Financial Reporting, as amended and supplemented by subsequent ASUs (collectively, “ASU 2020-04”), which provides practical expedients for contract modifications and certain hedging relationships associated with the transition from reference rates that are expected to be discontinued. This guidance is applicable for borrowing instruments, which use LIBOR as a reference rate, and is effective immediately, but is only available through December 31, 2022. The Company adopted the new standard as of January 1, 2022. The adoption of the standard had no material impact on the Company’s financial results. In November 2021, the FASB issued ASU 2021-10, Government Assistance ("Topic 832"), Disclosures by Business Entities about Government Assistance. The FASB issued this update to increase the transparency of government assistance including the disclosure of (1) the types of assistance, (2) an entity’s accounting for the assistance, and (3) the effect of the assistance on an entity’s financial statements. The main provisions of this update require the following disclosures about transactions with a government that are accounted for by applying a grant or contribution accounting model by analogy: (i) Information about the nature of the transactions and the related accounting policy used to account for the transactions (ii) The line items on the balance sheet and income statement that are affected by the transactions, and the amounts applicable to each financial statement line item (iii.) Significant terms and conditions of the transactions, including commitments and contingencies. The amendments in this update are effective for the Company in the annual period beginning after December 15, 2021. Early application of the amendments is permitted. The Company has elected to adopt on January 1, 2022. The adoption of the standard had no impact on the Company’s financial results. See Note 3 and Note 14 for required disclosures. Recently Issued Accounting Pronouncements Not Yet Adopted In October 2021, the FASB issued ASU 2021-08, Business Combinations ("Topic 805"), Accounting for Contract Assets and Contract Liabilities from Contracts with Customers. This update improves the accounting for acquired revenue contracts with customers in a business combination by addressing diversity in practice and inconsistency related to (1) recognition of an acquired contract liability; and (2) payment terms and their effect on subsequent revenue recognized by the acquirer. Specifically, the update requires that an entity (acquirer) recognize and measure contract assets and contract liabilities acquired in a business combination in accordance with ASC Topic 606, Revenue from Contracts with Customers. The amendments in this update are effective for the Company in the fiscal year beginning after December 15, 2022, including interim periods within those fiscal years. Early adoption of the amendments is permitted, including adoption in an interim period. The Company does not believe the adoption of this standard will have a material effect on its consolidated financial statements. In March 2022, the FASB issued ASU 2022-01, Derivatives and Hedging ("Topic 815") ("ASU 2022-01"). This update clarifies the guidance in Topic 815 on fair value hedge accounting of interest rate risk for portfolios and financial assets. Among other things, the amended guidance established the “last-of-layer” method for making the fair value hedge accounting for these portfolios more accessible and renamed that method the “portfolio layer” method. ASU 2022-01 is effective January 1, 2023 and is not expected to have a significant impact on the Company's consolidated financial statements.
