Item 1.01 Entry into a Material Definitive Agreement

Business Combination

Artius Acquisition Inc. is a blank check company incorporated as a Cayman Islands exempted company and formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Artius”). On February 16, 2021, Artius entered into an Agreement and Plan of Merger and Reorganization (the “Merger Agreement”) by and between Artius, Zero Carbon Merger Inc., a Delaware corporation and direct, wholly owned subsidiary of Artius (“Merger Sub”), and Micromidas, Inc., a Delaware corporation doing business as Origin Materials (“Micromidas”).

Pursuant to the Merger Agreement, (i) Artius will domesticate from a Cayman Islands exempted company to a Delaware corporation (the “Domestication”) and (ii) Merger Sub will merge with and into Micromidas with Micromidas continuing as the surviving entity and a wholly owned subsidiary of Artius (the “Merger” and together with the Domestication and the other transactions contemplated by the Merger Agreement, the “Business Combination”). In connection with the Domestication, Artius will change its name to “Origin Materials, Inc.” We refer to Artius following the Business Combination as “Origin.”

As a result of the Business Combination, each issued and outstanding Class A ordinary share and Class B ordinary share of Artius will convert into a share of Class A common stock of Origin (“Class A Common Stock”), and each issued and outstanding warrant to purchase Class A ordinary shares of Artius will be exercisable by its terms to purchase an equal number of shares of Class A Common Stock.

In connection with the Business Combination, Artius’s sponsor, Artius Acquisition Partners LLC (the “Sponsor”), agreed to subject 4,500,000 of its Class B ordinary shares (approximately 25% of the Class B ordinary shares held by the Sponsor) (the “Sponsor Vesting Shares”) to certain vesting and forfeiture provisions pursuant to the Sponsor Letter Agreement, as further described below under “Sponsor Letter Agreement”.

Conversion of Securities

The aggregate stock consideration to be distributed to Micromidas’s holders at the effective time of the Merger (the “Effective Time”) is 78,213,000 shares of Class A Common Stock, which is subject to certain downward adjustments pursuant to the Merger Agreement. At the Effective Time, by virtue of the Merger and without any action on the part of Artius, Merger Sub, Micromidas or the holders of any of Micromidas’s securities:

Earnout Consideration

As additional consideration for the Merger, after the Effective Time, Origin will issue to certain holders of Micromidas’s securities up to 25 million additional shares of Class A Common Stock (the “Earnout Shares”) as follows: (i) one third of the Earnout Shares will be issued when the volume weighted average price of Class A Common Stock (“VWAP”) equals or exceeds $15.00 for 10 consecutive trading days during the three year period following the closing of the Business Combination, (ii) one third of the Earnout Shares will be issued when VWAP equals or exceeds $20.00 for 10 consecutive trading days during the four year period following the closing of the Business Combination, and (iii) one third of the Earnout Shares will be issued when VWAP equals or exceeds $25.00 for 10 consecutive trading days during the five year period following the closing of the Business Combination.

Conditions to Closing

The Merger Agreement is subject to the satisfaction or waiver of certain customary closing conditions, including, among others, (i) the Artius Cash on Hand (as defined below) shall not be less than $525,000,000, (ii) approval of the business combination and related agreements and transactions by the respective stockholders of Artius and Micromidas, (iii) the consummation of a private placement pursuant to the Subscription Agreements (as defined below) for an aggregate purchase price of $200 million (the “PIPE Placement”), (iv) effectiveness of the registration statement on Form S-4 to be filed by Artius in connection with the Merger, (iii) expiration or termination of the waiting period under the Hart-Scott-Rodino Antitrust Improvements Act, (iv) receipt of conditional approval for listing on the Nasdaq the shares of Class A Common Stock to be issued in connection with the Closing, (v) that Artius have at least $5,000,001 of net tangible assets immediately after the Effective Time, (vi) the absence of any applicable law or order restraining, prohibiting or imposing any condition on the consummation of the Closing, (vii) the Investor Rights Agreement, the Subscription Agreements, the Company Transaction Support Agreements, any Additional Support Agreements, the Lock-Up Agreements and the Sponsor Letter Agreement (each as defined in the Merger Agreement) shall be in full force and effect and shall not have been rescinded by any of the parties thereto, and (viii) the directors and officers of Artius listed in the disclosure letter delivered by Micromidas to Artius concurrently with the execution of the Merger Agreement (the “Company Disclosure Letter”) shall have been removed from their respective positions or tendered their irrevocable resignations, effective as of the Effective Time.

“Artius Cash on Hand” means as of immediately prior to the Closing, an aggregate amount equal to the sum of the cash in the trust account established by Artius for the benefit of its public shareholders and certain other parties in connection with Artius’s initial public offering, net of any redemptions, plus the aggregate proceeds received by Artius from the PIPE Placement.

Covenants, Representations and Warranties

The Merger Agreement contains additional covenants, including, among others, providing for (i) the parties to conduct their respective businesses in the ordinary course in all material respects through the Closing, (ii) the parties to not solicit or enter into any agreements for certain alternative transactions, (iii) each party to prepare and deliver to the other party certain annual and interim financial statements, (iv) Artius and Micromidas to prepare and Artius to file a registration statement on Form S-4 and take certain other actions to obtain the requisite approval of the Artius stockholders of certain proposals regarding the Business Combination, and (v) the parties to use reasonable best efforts to obtain necessary approvals from governmental agencies. The Merger Agreement also contains customary representations and warranties by Artius, Merger Sub and Micromidas that do not survive the Closing.

Termination

The Merger Agreement may be terminated at any time prior to the Closing (i) by mutual written consent of Artius and Micromidas, (ii) by Artius, if certain approvals of the stockholders of Micromidas are not obtained within five business days after the registration statement on Form S-4 has been declared effective by the U.S. Securities and Exchange Commission (the “SEC”), or (iii) by either Artius or Micromidas in certain other circumstances set forth in the Merger Agreement including (a) if any applicable law is in effect making the consummation of the transactions contemplated by the Merger Agreement illegal or any final, non-appealable order is in effect permanently preventing the consummation of the transactions contemplated by the Merger Agreement, (b) in the event of certain uncured breaches by the other party, (c) if the required vote is not obtained at the meeting of the Artius stockholders, or (d) if the Closing has not occurred by August 31, 2021.

Certain Related Agreements

Subscription Agreements

Concurrently with the execution of the Merger Agreement, Artius entered into subscription agreements (the “Subscription Agreements”) with certain investors (the “PIPE Investors”), pursuant to which the PIPE Investors have agreed to purchase an aggregate of 20 million shares of Class A Common Stock for $10.00 per share in the PIPE Placement, for an aggregate purchase price equal to $200,000,000.

The Subscription Agreements for the PIPE Investors provide for certain registration rights. In particular, Artius is required to, within 15 business days after the Closing, submit to or file with the SEC a registration statement registering the resale of such shares. Additionally, Artius is required to use its commercially reasonable efforts to have the registration statement declared effective as soon as practicable after the filing thereof, but no later than the earlier of (i) the 60th calendar day following the filing date thereof (the “Effectiveness Deadline”), provided the Effectiveness Deadline shall be extended to the 90th calendar day following the filing date thereof if the registration statement is reviewed by, and comments thereto are provided from, the SEC, and Artius will use commercially reasonable efforts to have the registration statement declared effective within ten days of receipt of a SEC notice that the registration statement will not be “reviewed.” Artius must use commercially reasonable efforts to keep the registration statement effective until the earliest of: (i) two years from the date of effectiveness of the registration statement or (ii) the date the PIPE Investors no longer hold any registrable shares.

The Subscription Agreements will terminate with no further force and effect upon the earliest to occur of: (a) such date and time as the Merger Agreement is terminated in accordance with its terms; (b) the mutual written agreement of the parties to such Subscription Agreement; (c) if any of the conditions to closing set forth in such Subscription Agreement are not satisfied on or prior to the Closing and, as a result thereof, the transactions contemplated by the Subscription Agreement fail to occur; and (d) if the transactions contemplated by the Subscription Agreement are not consummated on or prior to August 31, 2021.

Sponsor Letter Agreement

Concurrently with the execution of the Merger Agreement, Artius entered into a sponsor letter agreement (the “Sponsor Letter Agreement”), by and between Artius and the Sponsor, pursuant to which the Sponsor agreed to, among other things, (i) vote in favor of the Artius Stockholder Voting Matters (as defined in the Merger Agreement), and (ii) pay any excess of Artius Transaction Expenses (as defined in the Merger Agreement) over the Artius Transaction Expense Cap (as defined in the Sponsor Letter Agreement).

In addition, pursuant to the Sponsor Letter Agreement, the Sponsor agreed to subject the 4.5 million Sponsor Vesting Shares to vesting and forfeiture as follows: (A) one third of the Sponsor Vesting Shares will vest when VWAP equals or exceeds $15.00 for ten consecutive trading days during the three year period following the Closing, (B) one third of the Sponsor Vesting Shares will vest when VWAP equals or exceeds $20.00 for ten consecutive trading days during the four year period following the Closing, and (C) one third of the Sponsor Vesting Shares will vest when VWAP equals or exceeds $25.00 for ten consecutive trading days during the five year period following the Closing. Sponsor Vesting Shares that remain unvested on the first business day after the fifth anniversary of the Closing date will be surrendered by Sponsor to Artius, without any consideration therefor.

Company Transaction Support Agreements

Concurrently with the execution of the Merger Agreement, Artius also entered into company transaction support agreements (the “Company Transaction Support Agreements”) by and among Artius, Micromidas and certain stockholders of Micromidas. Under the Company Transaction Support Agreements, such Micromidas stockholders agreed, as promptly as practicable following the effectiveness of the proxy statement/prospectus relating to the approval by Artius shareholders of the Merger, to execute and deliver a written consent with respect to the securities of Micromidas set forth in the Company Transaction Support Agreements adopting the Merger Agreement and approving the Merger. The securities of Micromidas owned by its stockholders who are party to the Company Transaction Support Agreements and subject to such agreements are sufficient to approve the adoption of the Merger Agreement.

Lock-Up Agreements

Concurrently with the execution of the Merger Agreement, the Sponsor, certain executive officers and directors of Micromidas and certain existing stockholders of Micromidas entered into a Lock-Up Agreement restricting, among other things, the transfer of Artius securities held by such contracting parties immediately following the Closing (the “Lock-Up Agreement”). Such restrictions begin at Closing and end on the earliest to occur of (i) the date that is 365 days after the date of the Closing, (ii) the first day after the date on which the closing price of the Class A Common Stock 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, and (iii) the date on which the Company completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction after the Closing date that results in all of the public stockholders of Artius having the right to exchange their shares of Class A Common Stock for cash, securities or other property.

Forward-Looking Statements Legend

This Current Report on Form 8-K contains certain “forward-looking statements” within the meaning of the Securities Act and the Exchange Act. Statements that are not historical facts, including statements about the pending Merger between Artius and Micromidas and the transactions contemplated thereby, and the parties’ perspectives and expectations, are forward-looking statements. Such statements include, but are not limited to, statements regarding the proposed transaction, including the anticipated cash available at Closing; the anticipated use of the combined company’s cash and cash equivalents; the benefits of the proposed transaction; integration plans; the combined company’s projected financial information and anticipated future financial condition and results of operations; Micromidas’s business strategy, estimated total addressable market, commercial operating plans, product development plans; and the expected timing of the transactions related to the Merger. The words “expect,” “believe,” “estimate,” “intend,” “plan” and similar expressions indicate forward-looking statements. These forward-looking statements are not guarantees of future performance and are subject to various risks and uncertainties, assumptions (including assumptions about general economic, market, industry and operational factors), known or unknown, which could cause the actual results to vary materially from those indicated or anticipated.

These forward-looking statements are subject to a number of risks and uncertainties, including the risks that: Micromidas, an early stage company, may not become profitable for many years; potential customers may withdraw from negotiations and indications of interest with Micromidas; Micromidas may fail to manage growth effectively; Micromidas’s indebtedness could increase its vulnerability to adverse economic and industry conditions, limit its ability to obtain additional financing, require the dedication of a substantial portion of its cash flow from operations to service its indebtedness, limit its flexibility in planning for, or reacting to, changes in its business and place Micromidas at a competitive disadvantage; Micromidas’s plants may not be completed in a timely or cost-effective manner; the design and construction of Micromidas’s proposed second production facility, Origin 2, may experience cost overruns and delays; Micromidas may not be able to secure government grants or subsidies to offset its operating costs and the costs of its research and development activities; the value of carbon credits associated with Micromidas’s products may decline; Micromidas could lose one or more of its significant customers; demand in the market for carbon-negative products may change; Micromidas may not be able to resolve the technological and logistical challenges associated with producing, marketing, selling and distributing renewable chemicals; Micromidas may lose market share to, or fail to gain market share from, its competitors; there could be a decrease in the availability or an increase in the price of Micromidas’s raw materials; changes in federal, state and local government laws, regulations and policies could cause the demand for bioplastics to decline and deter investment in the research and development of bioplastics; Micromidas may be unable to fund and make investments in developing intellectual property and other proprietary information to improve and scale its technological processes; Micromidas may have to defend against

claims of intellectual property infringement; Micromidas’s information technology systems may fail as Micromidas’s business grows; Micromidas’s may fail to retain key personnel or attract additional highly skilled employees; Micromidas and Artius may be unable to successfully or timely consummate the Merger, including as a result of any regulatory approvals that are not obtained, are delayed or are subject to unanticipated conditions that could adversely affect the combined company or the expected benefits of the Merger or if approval by the stockholders of Artius or Micromidas is not obtained; and the Merger may not result in the anticipated benefits; as well as the risks discussed in Artius’s final prospectus dated July 15, 2020 under the heading “Risk Factors,” and other documents Artius has filed, or will file, with the SEC, including a registration statement on Form S-4 that will include a proxy statement/prospectus. These risks and uncertainties may be amplified by the COVID-19 pandemic, which has caused significant economic uncertainty. If any of these risks materialize or underlying assumptions prove incorrect, actual results could differ materially from the results implied by these forward-looking statements. There may be additional risks that neither Artius nor Micromidas presently know, or that Artius or Micromidas currently believe are immaterial, that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements reflect Artius’s and Micromidas’s expectations, plans, or forecasts of future events and views as of the date of this Current Report on Form 8-K. Artius and Micromidas anticipate that subsequent events and developments will cause Artius’s and Micromidas’s assessments to change. Accordingly, you are cautioned not to place undue reliance on these forward-looking statements. Forward-looking statements relate only to the date they were made, and Artius, Micromidas and their affiliates undertake no obligation to update forward-looking statements to reflect events or circumstances after the date they were made except as required by law or applicable regulation.
