ERP Failure Wipes Out 23.4% of Tennant's Value
Shares of Tennant Company (NYSE: TNC) plummeted 23.4% on February 24, 2026, erasing significant shareholder value in a single trading session. The stock closed at $63.02, a drop of $19.28 from its previous close of $82.30. The sharp decline was a direct market reaction to the company's full-year 2025 financial results, announced the prior day, which fell far short of analyst expectations.
Tennant reported revenue of $291.6 million and earnings per share (EPS) of $0.48, missing consensus estimates by $28.85 million and $1.22, respectively. Management attributed the underperformance to the disastrous implementation of a new company-wide enterprise resource planning (ERP) system in North America, which created what it termed "unexpected challenges that constrained operating capacity."
Botched System Rollout Causes $30M Sales Loss
The failed ERP launch caused severe operational disruptions for the industrial cleaning equipment manufacturer. The company disclosed it was unable to properly process and ship customer orders, citing specific logistical hurdles like "manufacturing scheduling issues," "prolonged customer delays," and "order-management and fulfillment disruptions."
These operational failures translated into a direct financial impact, costing Tennant approximately $30 million in lost sales. Compounding the problem, the company now anticipates spending over $20 million in 2026 to remediate the system's issues, a fourfold increase from the roughly $5 million originally budgeted for the project's expenses.
Securities Fraud Probe Follows Misleading Statements
In the wake of the stock's collapse, law firms including Bleichmar Fonti & Auld LLP and The Portnoy Law Firm have initiated investigations into Tennant for potential violations of federal securities laws. The probes center on whether the company made false and misleading statements to investors leading up to the public disclosure of the ERP system's failure.
Investigators are scrutinizing prior management assurances that the project was "progressing as we’ve anticipated," was "on time and on budget," and that a related launch in its Asia-Pacific region had been "successful." These positive characterizations now appear to directly contradict the severe operational breakdown and financial damage revealed in the February 23 financial report, forming the basis for the potential class-action lawsuits.
