The Law Offices of Frank R. Cruz said class action lawsuits have been filed on behalf of shareholders of Blaize Holdings, Alibaba Group Holding Limited, Alarum Technologies and Replimune Group. Investors have until October 5, 2026, to file a lead plaintiff motion in each case. The allegations include improper revenue recognition and transactions at Blaize, undisclosed links between Alibaba and China’s Ministry of Industry and Information Technology and alleged AI-model distillation attacks, illegal activity by Alarum subsidiary NetNut involving customers’ home internet devices, and undisclosed regulatory and clinical-study deficiencies related to Replimune’s biologics license application. The firm said shareholders who suffered losses may contact it about their legal rights, while investors may also retain counsel of their choice, take no action and remain absent members of the classes.
