iRobot stock tanks after company files for bankruptcy: Roomba maker iRobot sought Chapter 11 protection as debt, Chinese competition, and a 46% Vietnam tariff crushed margins. The firm plans a buyout by Picea Robotics, wiping out shareholders despite $682 million in 2024 revenue. Shares fell from $4.32 on Friday to around $0.97 in premarket trading, wiping out nearly all remaining equity value. The company confirmed that common shareholders will receive no recovery if the court approves the restructuring plan. The company says customer support, apps, and product service will continue without disruption.
