On July 13, 2020, the Registration Statement on Form S-1 (File
No. 333-239421) (the Registration Statement) relating to the initial public offering (the IPO) of Artius Acquisition Inc. (the Company) was
declared effective by the U.S. Securities and Exchange Commission, and the Company subsequently filed, on July 13, 2020, a registration statement on Form S-1 (File
No. 333-239841) pursuant to Rule 462(b) under the Securities Act of 1933, as amended, which was effective immediately upon filing. On July 16, 2020, the Company consummated the IPO of 72,450,000
units (the Units), including the issuance of 9,450,000 Units as a result of the underwriters exercise in full of their over-allotment option. Each Unit consists of one Class A ordinary share of the Company, par value
$0.0001 per share (Class A Ordinary Shares), and one-third of one redeemable warrant of the Company, each whole warrant entitling the holder thereof to purchase one
Class A Ordinary Share at an exercise price of $11.50 per share, subject to adjustment. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to the Company of $724,500,000.
On July 13, 2020, the Company effected a share recapitalization with respect to the Companys Class B ordinary shares, par
value $0.0001 per share, resulting in the Companys initial shareholders holding an aggregate of 18,112,500 founder shares.
Substantially concurrently with the closing of the IPO, the Company completed the private sale of 11,326,667 warrants (the Private
Placement Warrants) at a purchase price of $1.50 per Private Placement Warrant, to the Companys sponsor, Artius Acquisition Partners LLC (the Sponsor), generating gross proceeds to the Company of approximately
$16,990,000. The Private Placement Warrants are identical to the warrants sold as part of the Units in the IPO, except that, so long as they are held by the Sponsor or its permitted transferees: (i) they will not be redeemable by the Company
(except in certain redemption scenarios when the price per Class A Ordinary Share equals or exceeds $10.00 (as adjusted)), (ii) they (including the Class A Ordinary Shares issuable upon exercise of these warrants) may not, subject to
certain limited exceptions, be transferred, assigned or sold until 30 days after the completion of the Companys initial business combination, (iii) they may be exercised by the holders on a cashless basis, and (iv) they (including
the Class A Ordinary Shares issuable upon exercise of these warrants) are entitled to registration rights.
A total of $724,500,000,
comprised of proceeds from the IPO and the sale of the Private Placement Warrants, was placed in a U.S.-based trust account at JP Morgan Chase Bank, N.A., maintained by Continental Stock Transfer & Trust Company, acting as trustee. Except
with respect to interest earned on the funds in the trust account that may be released to the Company to pay its taxes, if any, the funds held in the trust account will not be released from the trust account until the earliest to occur of:
(i) the completion of the Companys initial business combination, (ii) the redemption of any public shares properly submitted in connection with a shareholder vote to amend the Companys amended and restated memorandum and
articles of association (A) to modify the substance or timing of its obligation to allow redemption in connection with its initial business combination or to redeem 100% of its public shares if the Company does not complete its initial business
combination within 24 months from the closing of the IPO or (B) with respect to any other provision relating to shareholders rights or pre-initial business combination activity and (iii) the
redemption of the Companys public shares if the Company has not completed its business combination within 24 months from the closing of the IPO, subject to applicable law.
