Tennant Company (TNC) Investigation:

The investigation is focused on the propriety of Tennant’s disclosures about the progress of its efforts to modernize its North America ERP system and related challenges, if any.

As recently as November 4, 2025, Tennant touted the success of its Asia Pacific ERP modernization and instilled confidence in investors about its North America ERP system modernization. At the time, the company was well into its fourth quarter.

Investors’ expectations were dashed on February 24, 2026, when Tennant reported dismal Q4 and FY 2025 financial results.

The company’s GAAP net income for 2025 came in at just $43.8 million, a whopping year-over-year decrease of about 47%. Worse, during Q4 2025, Tennant sustained a net loss that was 166% downward move from its net income for the year earlier period.

During the related earnings call, management revealed that during the first week of November the North America ERP go-live “introduced severe functionality issues that limited our ability to enter orders, ship products, and service our customers.” Management further said, “[i]n North America, we lost three, four weeks of machine order entry and parts shipping capability.”

Tennant management quantified the adverse financial impact: “[t]hese dynamics, combined with our limited ability to operate plants at normal capacity, resulted in an estimated $30 million impact on net sales.” Management also revealed that the Q4 challenges will continue into early 2026.

The market swiftly reacted, erasing about $343 million of Tennant’s market capitalization.

“We’re investigating precisely when Tennant knew of serious problems with its North America ERP and whether it may have concealed information crucial to investors’ decisions,” said Reed Kathrein, the Hagens Berman partner leading the investigation.
