Atkore Inc. (ATKR) witnessed a sharp decline of 19.71% in its stock price during intraday trading on Tuesday, February 4, 2025. The plummet came after the company reported disappointing first-quarter fiscal 2025 results that missed analysts' estimates and lowered its full-year guidance.

For the quarter ended December 27, 2024, Atkore reported net sales of $661.6 million, falling short of the consensus estimate of around $680 million. The company's operating income of $67.9 million also lagged behind analysts' expectations of approximately $75 million.

Atkore's Q1 adjusted net income per diluted share came in at $1.63, missing the FactSet consensus estimate of $1.55. The company's net income for the quarter was $46.3 million, significantly lower than the $138.4 million reported in the same period last year.

In addition to the weaker-than-anticipated Q1 performance, Atkore also revised its full-year 2025 guidance. The company now expects its adjusted EBITDA to be in the range of $375 million to $425 million, down from its previous guidance. Atkore also lowered its adjusted net income per diluted share outlook to $5.75 - $6.85, compared to its previous guidance of $7.80 - $8.90.

The disappointing Q1 results and lowered full-year guidance seem to have rattled investors, leading to the sharp sell-off in Atkore's stock on Tuesday. The company's shares were down as much as 19.71% in intraday trading, reflecting investor concerns over the weaker-than-expected performance and uncertain outlook.
