Not sure about those other stocks . But Nemaska submitted a plan to the Court to cancel their shares and issued new worthless shares that are still in accounts . And will be forever if the owner of the account does nothing with them . So I'm pretty sure the others submitted some type of plan to the Court to cancel shares . BioAmber had no plan. But if they did the same results would have happened.
Your shares are being exchanged (on a one-for-one basis for common shares of Residual Nemaska Lithium) as part of a reorganization of the Corporation and its affiliates. However, as indicated above, unfortunately there is no residual value for shareholders of Residual Nemaska Lithium in connection with the CCAA proceedings.
