Our Common Shares are listed on the Nasdaq Capital Market (“Nasdaq”) and began trading (regular way) on June 22, 2023 under the symbol “CISS”. On February 22, 2024, the closing sale price as reported on Nasdaq of the Common Shares was $0.12 per share. The public offering price of the Units will be determined between us and investors based on market conditions at the time of pricing, and may be at a discount to the then current market price of our Common Shares. The assumed public offering price and related Class C-1 Warrant and Class C-2 Warrant exercise prices used throughout this prospectus may not be indicative of the actual public offering price. The actual public offering price may be based upon a number of factors, including our history and our prospects, the industry in which we operate, our past and present operating results, the previous experience of our executive officers and the general condition of the securities markets at the time of this offering. There is no established trading market for the pre-funded warrants, Class C-1 Warrants, or Class C-2 Warrants and we do not expect an active trading market to develop. We do not intend to list the pre-funded warrants, Class C-1 Warrants, or Class C-2 Warrants on any securities exchange or other trading market. Without an active trading market, the liquidity of these securities will be limited.
