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 (NYSE: TNC) 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.
