Re: Registration Statement on Form S-3

Ladies and Gentlemen:

We refer to the Registration Statement on Form S-3 (the “Registration Statement”) being filed by Codexis, Inc., a Delaware corporation (the “Company”), with the Securities and Exchange Commission (the “SEC”) under the Securities Act of 1933, as amended (the “Securities Act”). The Registration Statement includes two prospectuses: (i) a base prospectus (the “Base Prospectus”); and (ii) a sales agreement prospectus (the “Sales Agreement Prospectus”) covering the issuance and sale from time to time of shares (the “Placement Shares”) of the Company’s common stock, $0.0001 par value per share (the “Common Stock”), having an aggregate offering price of up to $75,000,000 that may be sold under the Sales Agreement, dated May 2, 2024 (the “Sales Agreement”), between the Company and Cantor Fitzgerald & Co. (the “Agent”). The Registration Statement, including the Base Prospectus (as supplemented from time to time by one or more prospectus supplements) and the Sales Agreement Prospectus (as supplemented from time to time by one or more prospectus supplements), will provide for the registration by the Company of the sale of up to $200,000,000 aggregate offering price of:

 

  (a)

shares of Common Stock (the “Base Prospectus Shares”);

 

  (b)

shares of the Company’s preferred stock, $0.0001 par value per share (the “Preferred Stock”);

 

  (c)

debt securities of the Company (the “Debt Securities”);

 

  (d)

warrants of the Company to purchase Base Prospectus Shares, shares of Preferred Stock or Debt Securities (the “Warrants”);

 

  (e)

units (the “Units”), each consisting of two or more types of securities listed in clauses (a) through (d) above; and

 

  (f)

the Placement Shares.

The Base Prospectus Shares, the Preferred Stock, the Debt Securities, the Warrants, the Units and the Placement Shares are collectively referred to herein as the “Securities.”

Unless otherwise specified in the applicable prospectus supplement:

 

  (1)

the Debt Securities will be issued under an indenture (the “Indenture”) to be entered into between the Company and a trustee (the “Trustee”);

 

  (2)

the Warrants will be issued under a warrant agreement (the “Warrant Agreement”) to be entered into between the Company and a warrant agent (the “Warrant Agent”); and

in each case substantially in the form that has been or will be filed as one or more exhibits to the Registration Statement.

This opinion letter is being delivered in accordance with the requirements of Item 601(b)(5) of Regulation S-K under the Securities Act.

We have examined the Registration Statement, the exhibits thereto, the Sales Agreement, the amended and restated certificate of incorporation of the Company (the “Charter”), the amended and restated bylaws of the Company (the “Bylaws”), and the resolutions (the “Resolutions”) adopted by the board of directors of the Company (the “Board”) relating to the Registration Statement, the Sales Agreement and the issuance of the Placement Shares by the Company. We have also examined originals, or copies of originals certified to our satisfaction, of such agreements, documents, certificates and statements of the Company and others, and have examined such questions of law, as we have considered relevant and necessary as a basis for this opinion letter. We have assumed the authenticity of all documents submitted to us as originals, the genuineness of all signatures, the legal capacity of all persons and the conformity with the original documents of any copies thereof submitted to us for examination. As to facts relevant to the opinions expressed herein, we have relied without independent investigation or verification upon, and assumed the accuracy and completeness of, certificates, letters and oral and written statements and representations of public officials and officers and other representatives of the Company.
