Lowey Dannenberg, P.C. is Investigating Tennant Company (NYSE: TNC) for Potential Violations of the Federal Securities Laws

Law firm Lowey Dannenberg is investigating Tennant Company for potential federal securities violations following the company's February 2026 disclosure of severe operational disruptions from its ERP system rollout in North America. The disruptions caused approximately $30 million in lost sales and required an additional $20 million in remediation costs. The revelation contradicted prior investor assurances that the project was on track, resulting in a 23% stock price decline from $82.30 to $63.02 per share.
