Explanatory Note

This Amendment No. 1 on Form 8-K/A (this “Amendment”) amends the Current Report on Form 8-K furnished by Calyxt, Inc. (the “Company”) to the Securities and Exchange Commission (the “SEC”) on August 2, 2018 (the “Form 8-K”). Due to clerical errors, the Form 8-K inadvertently included (i) an outdated address for the Company’s principal executive offices and (ii) an incorrect conformed signature. The original signature for the Form 8-K was obtained from Federico Tripodi, the Company’s Chief Executive Officer, prior to the submission of the Form 8-K. This Amendment is furnished solely to correct such clerical errors by providing the correct address for the Company’s new principal executive offices and correcting the signature page. Other than as specifically set forth in this Amendment with respect to the cover page and signature page, no other modifications to the Form 8-K are being made by this Amendment. The text of Item 2.02 and the press release attached as an exhibit are unchanged from the Form 8-K.

On August 1, 2018, Calyxt, Inc. (the “Company”) announced its financial results for the quarter ended June 30, 2018. The full text of the press release issued in connection with the announcement is furnished as Exhibit 99.1 to this Current Report on Form 8-K. 

The information in Item 2.02 of this Form 8-K (including Exhibit 99.1) shall not be deemed “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended, or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference under the Securities Act of 1933, as amended, except as expressly set forth by specific reference in such a filing, regardless of any general incorporation language in any such filing, unless the Company expressly sets forth in such filing that such information is to be considered “filed” or incorporated by reference therein.
