On June 23, 2021, in connection with an extraordinary general meeting of shareholders (the “Special Meeting”), shareholders of Artius Acquisition Inc. (the “Company” or “Artius”) approved the Origin Materials, Inc. 2021 Equity Incentive Plan (the “2021 Plan”), which initially makes available a maximum number of shares of Origin Materials, Inc.’s (“Origin Materials, Inc.” refers to Artius after consummation of the Business Combination, as defined below) common stock equal to 10% of the fully-diluted shares of common stock of Origin Materials, Inc. outstanding immediately following consummation of the Business Combination (the “Closing”). Additionally, the number of shares of Origin Materials, Inc. common stock reserved for issuance under the 2021 Plan will automatically increase on January 1 of each year, starting on January 1, 2022 and ending on and including January 1, 2031, in an amount equal to the lesser of (i) 5% of the aggregate number of shares of Origin Materials, Inc. common stock outstanding (or issuable upon conversion or exercise of outstanding instruments) on the final day of the immediately preceding calendar year, (ii) such smaller number of shares as is determined by Origin Material’s board of directors, or (iii) a lesser number of shares of Origin Materials, Inc. common stock that would not result in the share reserve exceeding 15% of the fully-diluted shares of Origin Materials, Inc. common stock as of the final day of the immediately preceding calendar year. The maximum number of shares of Origin Materials, Inc. common stock that may be issued pursuant to the exercise of incentive stock options granted under the 2021 Plan will be a number of shares equal to 300% of the initial share reserve described above. A summary of the 2021 Plan is included in the Company’s definitive proxy statement/prospectus (the “Proxy Statement/Prospectus”) filed with the U.S. Securities and Exchange Commission (“SEC”) on May 27, 2021 and mailed to shareholders on or about June 1, 2021, and is incorporated by reference, which summary is qualified in all respects by the full text of the 2021 Plan, included as Annex H to the Proxy Statement/Prospectus.

On June 23, 2021, in connection with the Special Meeting, shareholders of Artius approved the Origin Materials, Inc. 2021 Employee Stock Purchase Plan (the “ESPP”), which initially makes available for sale a maximum number of shares of Origin Materials, Inc’s common stock equal to 1% of the total number of shares of Origin Materials, Inc. common stock issued and outstanding (or issuable upon conversion or exercise of outstanding instruments) as of immediately after Closing. Additionally, the number of shares of Origin Materials, Inc. common stock reserved for issuance under the ESPP will automatically increase on January 1 of each year, starting on January 1, 2022 and ending on and including January 1, 2031, in an amount equal to the lesser of (i) 1% of the aggregate number of shares of Origin Materials, Inc. common stock outstanding (or issuable upon conversion or exercise of outstanding instruments) on the final day of the immediately preceding calendar year, (ii) a number of shares equal to 200% of the initial share reserve described above or (iii) such smaller number of shares as is determined by Origin Materials, Inc.’s board of directors. A summary of the ESPP is included in the Company’s Proxy Statement/Prospectus and is incorporated by reference, which summary is qualified in all respects by the full text of the ESPP, included as Annex I to the Proxy Statement/Prospectus.

On June 23, 2021, Artius convened the Special Meeting held in connection with the Company’s previously announced business combination (the “Business Combination”) with Micromidas, Inc., a Delaware corporation doing business as Origin Materials (“Micromidas”), pursuant to the Agreement and Plan of Merger and Reorganization, dated as of February 16, 2021 (as amended by the letter agreement dated March 5, 2021, and as further amended or modified from time to time, the “Merger Agreement”), by and among Artius, Micromidas and Zero Carbon Merger Sub Inc., a Delaware corporation and a direct, wholly-owned subsidiary of Artius (“Merger Sub”). Each proposal voted on at the Special Meeting is described in greater detail in the Proxy Statement/Prospectus.

As of the close of business on May 19, 2021, the record date for the Special Meeting, there were an aggregate of 72,450,000 Class A ordinary shares of Artius, par value $0.0001 per share, and 18,112,500 Class B ordinary shares of Artius, par value $0.0001 per share (the Class A and Class B together, the “Artius Ordinary Shares”), outstanding, each of which was entitled to one vote at the Special Meeting. At the Special Meeting, a total of 58,972,042 Artius Ordinary Shares, representing approximately 65.11% of the outstanding ordinary shares entitled to vote, were present virtually or by proxy, constituting a quorum.

Each of the proposals voted on at the Special Meeting was approved by the Company’s shareholders, and the voting results are set forth below.

1. The Domestication Proposal – To approve by special resolution under Cayman Islands law, assuming the Transaction Proposal is approved and adopted, the change of Artius’s corporate structure and domicile (the “Domestication”) by way of continuation from an exempted company incorporated under the laws of the Cayman Islands to a corporation incorporated under the laws of the State of Delaware (such proposal, the “Domestication Proposal”).

2. The Transaction Proposal – To approve by ordinary resolution under Cayman Islands law and adopt the Merger Agreement and the transactions contemplated thereby. Upon consummation of the transactions contemplated by the Merger Agreement, including the Domestication, Merger Sub will be merged with and into Micromidas, the separate existence of Merger Sub shall cease, and Micromidas will survive and become a wholly-owned subsidiary of Artius (such proposal, the “Transaction Proposal”).

3. The Issuance Proposal – To approve by ordinary resolution under Cayman Islands law, for the purposes of complying with the applicable listing rules of the Nasdaq Listed Company Manual, the issuance of more than 20% of Artius’s issued and outstanding voting power to Micromidas stockholders in connection with the Business Combination (such proposal, the “Issuance Proposal”).

4. The Interim Charter Proposal – To approve and adopt by special resolution under Cayman Islands law the amendment and restatement of the Amended and Restated Memorandum and Articles of Association of Artius by the deletion in their entirety and the substitution in their place of the proposed Interim Certificate of Incorporation and Bylaws, as defined in the Proxy Statement/Prospectus, which if approved, would be in effect as of the Domestication and prior to the effective time of the Merger (the “Effective Time”), and as of the Domestication respectively (such proposal, the “Interim Charter Proposal”). Copies of the proposed Interim Certificate of Corporation and the Bylaws are attached to the Proxy Statement/Prospectus as Annex C and Annex D, respectively.

5. The Charter Proposal – To approve and adopt by special resolution under Cayman Islands law the amendment and restatement of the proposed Interim Certificate of Corporation that is in effect immediately prior to the Effective Time by the deletion in its entirety and the substitution in its place of the proposed Certificate of Incorporation of Artius, which, if approved, would take effect at the Effective Time (such proposal, the “Charter Proposal”). A copy of the Certificate of Incorporation is attached to the Proxy Statement/Prospectus as Annex E.

6. The Organizational Documents Proposal – To approve and adopt eight separate proposals with respect to certain material differences between the existing organizational documents of Artius and the proposed Interim Certificate of Incorporation, the proposed Certificate of Incorporation and the proposed Bylaws of Artius (such proposal, the “Organizational Documents Proposal”). The vote to approve the Organizational Documents Proposal is an advisory vote, and therefore, is not binding on Artius, Micromidas, the board of directors of Artius or the board of directors of Micromidas.

7. The Equity Incentive Plan Proposal – To approve by ordinary resolution under Cayman Islands law the 2021 Plan and any form award agreements thereunder, a copy of which is attached to the Proxy Statement/Prospectus as Annex H (such proposal, the “Equity Incentive Plan Proposal”).
