What Happened?

Shares of filtration equipment manufacturer Donaldson (NYSE:DCI) fell 11.6% in the afternoon session after the company reported fourth-quarter 2025 results where earnings per share (EPS) missed estimates and it lowered its full-year profit forecast.

Donaldson posted adjusted earnings of $0.83 per share, which missed Wall Street’s expectations of $0.89. Revenue of $896.3 million was roughly in line with estimates. While total sales grew 3% year-on-year, the company’s profitability weakened, driven by pressure on profit margins from operational inefficiencies. Specifically, its gross margin fell to 33.4% from 35.2% in the prior year’s quarter. Compounding the issue, Donaldson revised its outlook for the full year, lowering its guidance for adjusted earnings per share. The combination of the earnings miss and the reduced forecast led to the negative investor reaction.
