Key Details of the Tennant ($TNC) Class Action Investigation:

• Investigation Overview: Securities fraud related to Tennant's implementation and rollout of its new, company-wide enterprise resource planning ("ERP") system
• Stock Decline: February 24, 2026 – 23.4% Stock Drop

Why is Tennant Being Investigated for Securities Fraud?

Tennant manufactures industrial cleaning equipment, including large mechanical floor scrubbers and sweepers used in warehouses, retail stores, and other commercial facilities.

BFA is investigating whether Tennant made false and misleading statements to investors regarding the implementation and rollout of a large-scale ERP system. For instance, Tennant assured investors the project was "progressing as we've anticipated," was "on time and on budget," and that the launch of the ERP in its Asia-Pacific region had been "successful," with Tennant stating it had "mitigated disruptions and stabilized operations."

Why did Tennant's Stock Drop?

On February 24, 2026, Tennant revealed that the rollout of its new ERP system in North America caused severe operational disruptions, including that it was unable to process and ship customer orders following the launch of the system. As a result, Tennant lost roughly $30 million in sales and would need to spend more than $20 million in 2026 to remediate the issues, compared to roughly $5 million the company had planned to spend.

This news caused the price of Tennant stock to drop $19.28 per share, more than 23%, from a closing price of $82.30 per share on February 23, 2026, to $63.02 per share on February 24, 2026.
