This Form 144 from MPM Asset Management LLC, an institutional shareholder, signals an intent to sell an additional 20,608 shares. While the individual proposed sale is modest, it is part of a broader, ongoing liquidation by the MPM group, which has sold over $180,000 worth of shares in the past two days. This persistent selling by a major institutional investor is a significant negative signal, especially given the company's recent disclosure of substantial doubt about its ability to continue as a going concern and a 64% workforce reduction. Investors should view this as a lack of confidence from a key shareholder during a critical period for the company.
