Whirlpool's stock experienced a significant 7.26% plunge in post-market trading following the release of its disappointing fourth-quarter financial results and below-expectations guidance for 2026.

The appliance maker reported quarterly revenue of $4.098 billion, missing the analyst consensus estimate of $4.269 billion. Adjusted earnings per share came in at $1.10, falling short of the $1.52 to $1.57 estimates. Sales declined in key regions, with North American revenue decreasing 0.9% and Latin American revenue falling 4.6%, primarily driven by lower sales volumes and aggressive discounting during the Black Friday period.

The company's 2026 guidance also contributed to investor concerns, with Whirlpool forecasting GAAP earnings per share of approximately $6.25, below Wall Street's projection of $6.73 per share. Management cited a negative macroeconomic environment in Argentina and aggressive competition in Brazil as additional headwinds affecting margins.
