Tennant stock plunges 23% amid investigation over ERP system rollout issues.

Tennant Company faces a securities fraud investigation after its stock dropped 23.4% following severe operational disruptions caused by the rollout of a new ERP system in North America. The company lost about $30 million in sales and expects to spend over $20 million to fix the problems, far exceeding initial estimates. The investigation centers on whether Tennant misled investors by claiming the ERP implementation was on track and successful.
