Lowey Dannenberg P.C. is investigating Tennant Company for potential violations of federal securities laws. The investigation follows Tennant's February 24, 2026 disclosure that its new ERP system rollout in North America caused severe operational disruptions, including an inability to process and ship customer orders, resulting in roughly $30 million in lost sales and requiring more than $20 million in remediation spending in 2026, compared to a planned $5 million. This came after the company had repeatedly assured investors the project was on time and on budget and that the Asia-Pacific launch had been successful. The news caused Tennant's stock to drop $19.28 per share, or more than 23%, from $82.30 to $63.02 in one day. The law firm is urging investors who suffered losses to contact them or check eligibility on its case management platform.
