Certain 6-Ks also incorporate by reference financial tables, interactive data files and other exhibits into the company’s shelf registration statements and equity compensation plans.
Investors can also review filings that describe capital markets activities, such as at-the-market (ATM) equity offering programs and changes to the ratio of American Depositary Shares (ADSs) to ordinary shares, which effectively function as reverse ADS splits. These documents outline the terms under which Chemomab may sell ADSs, the role of its sales agent, and related legal opinions.
