Subject: Update on Origin Materials Inc. Merger and Recent SEC Statement

Dear Artius Acquisition Inc. PIPE Investors:

We are pleased to share with you that earlier today we filed Amendment No. 1 to our proxy statement/ prospectus with the Securities and Exchange Commission (the “SEC”) in connection with the proposed business combination between Artius Acquisition Inc. (“Artius”) and Micromidas, Inc., doing business as Origin Materials Inc. (“Origin Materials”), which was originally announced on February 17, 2021. With this filing, we have taken one more step towards the successful completion of the business combination and our goal of investing in Origin Materials’ disruptive platform technology to decarbonize the materials industry supply chain.

As we continue to move closer to holding our shareholder vote and completing the merger, we would like to provide you with an update on recent developments in Origin Materials’ business, including its entry into agreements with several new strategic partners that will result in an increase in its order book (including capacity reservations and customer options) from a previously disclosed $1 billion to $1.9 billion. We would also like to update you on the actions Artius has taken to restate its financial statements for the periods ended July 16, 2020, September 30, 2020 and December 31, 2020, in response to the April 12 statement of the SEC Staff on accounting and reporting considerations for warrants issued by SPACs.

Proxy Statement/Prospectus Amendment

Artius filed its preliminary proxy statement/prospectus with the SEC on March 8, 2021 and received comments from the SEC on April 5, 2021. Since then, Origin Materials and we have diligently worked together to respond to the SEC’s comments, and to address the implications of the SEC’s April 12 statement. With our filing of Amendment No. 1 to our proxy statement/prospectus, we are confident that we have addressed the SEC’s comments. We also believe we have addressed the issues raised in the April 12 SEC Staff statement by filing a Form 8-K regarding our previous financial statements on April 29, and an amended Form 10-K on April 30 (available on EDGAR today, May 3) containing our restated financial statements.

Origin Materials Business Highlights

Since the announcement of the proposed business combination on February 17, Origin Materials has continued to expand its strategic customer partnerships in order to meet demand for its carbon-negative materials. On April 19, 2021, Origin Materials announced that it increased its customer demand from offtake agreements (including customer options) and capacity reservations by 90% to $1.9 billion from the $1 billion previously disclosed, and has entered into the following new strategic customer partnerships:



April 27, 2021: Partnership with Mitsubishi Gas Chemical, Inc., a global leader in basic and fine chemicals and advanced materials, to industrialize and manufacture advanced chemicals and materials built on the Origin carbon-negative technology platform.



April 19, 2021: Strategic alliance with PrimaLoft, an advanced material technology company and a world leader in the development of high-performance insulations and fabrics, to develop carbon-negative insulating fiber for outdoor gear, bedding and apparel.


April 19, 2021: Partnership with Solvay, a global leader in chemicals and materials, to develop and industrialize advanced carbon-negative materials for the automotive industry.



April 12, 2021: Partnership with Packaging Matters, a packaging innovation leader, to develop advanced carbon-negative packaging solutions, building on an existing 10-year supply agreement.




April 6, 2021: Partnership with AECI Much Asphalt, the largest commercial asphalt producer in southern Africa, to develop novel, low-carbon asphalt built on the Origin carbon-negative technology platform.



April 5, 2021: Partnership with AECI Sans Technical Fiber, a leader in engineered thread for high-performance apparel and automotive applications, to develop carbon negative materials for apparel and automotive applications.

These new partnerships further validate Origin’s carbon-negative technology platform and demonstrate its ability to disrupt and decarbonize the materials industry supply chain, grow its business globally, and deliver long-term shareholder value.

Origin Materials has also continued to add key technical talent to the company with expertise in industrial chemical engineering, petrochemicals, solids processing and refining and renewable energy. In addition, Artius plans to bolster its post-combination board of directors by adding industry leaders from Clorox and Procter & Gamble who bring a proven track record in driving growth and innovation in world class CPG companies.

Financial Statements Restatement In Response to the April 12 SEC Staff Statement on SPAC Warrants

We have been working diligently with our accounting financial consultant, Calabrese Consulting, LLC, and our independent registered accounting firm, Marcum LLP, to correct a non-cash item reported in our financial statements for the periods ended July 16, 2020, September 30, 2020 and December 31, 2020. As a result, our previously issued financial statements have been restated to correct the classification of Artius’s outstanding warrants as equity instruments and instead record them as liabilities on our balance sheet and measured at fair value at inception and on a recurring basis. As mentioned above, on April 12, the Staff of the SEC released a statement relating to the accounting classification of warrants issued by SPACs, stating that warrant terms should be evaluated to determine if warrants were being properly classified by SPACs. We believe that this statement will result in most SPACs reclassifying their warrants as liabilities rather than equity instruments and recognizing non-cash liabilities and charges in their financial statements. As you are aware, our warrant terms were fully disclosed in our IPO prospectus and we do not believe that the accounting treatment of our warrants is relevant to the intrinsic value of Artius, or the value of the business of the post-combination company. However, like many other SPACs have or will, we have determined to restate our financial statements to align with the SEC Staff statement and record our warrants as liabilities. As a result of this change in the accounting treatment for our warrants, we were advised by our auditors that we also needed to change the allocation of certain expenses incurred in connection with our July 2020 initial public offering, which change is reflected in our restated financial statements for the period ending September 30, 2020. No other information in our prior financial statements has changed in response to the SEC Staff statement.

Moving Forward

In summary, despite the unexpected issuance of the SEC Staff statement on April 12, we continue to move the business combination forward and Origin Materials continues to expand its strategic partnership network, significantly increase customer demand, and add expertise to its management team and to the board of directors of the post-combination company. We will continue working towards the successful completion of our business combination, which will allow us to achieve our goal of delivering long-term value to our shareholders and investors. On behalf of our Board, I would like to thank you for your support of Artius Acquisition Inc. Please feel free to reach out to me at if you have any questions or if you would like to receive a business update from the management team of Origin Materials.
