Shares of Tennant Company fell over 20% on February 24, 2026, after the company reported Q4 results that missed analyst expectations and issued FY26 guidance below consensus estimates. Tennant disclosed that net sales declined year over year and that adjusted earnings fell sharply, citing operational disruptions related to its Enterprise Resource Planning system transition that negatively impacted production, margins and volumes. The company also projected continued pressure into 2026, signaling a slower recovery than investors anticipated. Block & Leviton is investigating.
