Calyxt, Inc. (NASDAQ: CLXT) ("Calyxt" or the "Company"), a plant-based synthetic biology company, today announced the placement to an institutional investor in an underwritten offering of 3,880,000 shares of its common stock, pre-funded warrants to purchase up to 3,880,000 shares of its common stock, and common warrants to purchase up to 7,760,000 shares of its common stock (the "Offering"). The shares of common stock and the pre-funded warrants are each being sold in combination with corresponding common warrants, with one common warrant to purchase one share of common stock for each share of common stock or each pre-funded warrant sold. The pre-funded warrants will have an exercise price of $0.0001 per share of common stock and the common warrants will have an exercise price of $1.41 per share of common stock.  The pre-funded warrants will be immediately exercisable and remain exercisable until exercised, while the common warrants will be exercisable six months after the date of issuance and will have a term of five years from the date of exercisability. The aggregate public offering price for each share of common stock or each pre-funded warrant and, in each case, an accompanying common warrant is $1.41. All securities to be sold in the Offering were sold by the Company.

The Company expects to close the Offering on or about February 23, 2022, subject to the satisfaction of customary closing conditions. The gross proceeds from the Offering are expected to be approximately $10.9 million, assuming none of the accompanying common warrants issued in the Offering are exercised. The Company intends to use the net proceeds from the Offering for enhancing the capabilities of its BioFactory production system and increasing its capacity to produce at larger scales, continuing to build out its PlantSpring technology platform and artificial intelligence / machine learning capabilities, furthering customer relationships, and for working capital and general corporate purposes.

There is no established public trading market for the pre-funded warrants or the common warrants and the Company does not expect a market to develop. Additionally, the Company does not intend to apply for the listing of the pre-funded warrants or the common warrants on any national securities exchange or other nationally recognized trading system.
