Entegris Inc. (ENTG) shares plummeted 5.68% in pre-market trading on Thursday as the semiconductor materials supplier issued lower-than-expected earnings guidance for the first quarter of 2025, overshadowing a strong fourth-quarter performance.

The company reported fourth-quarter non-GAAP earnings of $0.84 per diluted share, surpassing analyst estimates of $0.78. Net sales rose 4.6% year-over-year to $849.8 million, beating expectations of $823.1 million. However, Entegris' outlook for the first quarter fell short, with projected adjusted earnings per share of $0.64 to $0.71, below the consensus estimate of $0.74.

Entegris CEO Bertrand Loy acknowledged the limited visibility beyond advanced logic and AI-driven applications, stating, "We have yet to see evidence of a significant broad-based semiconductor market rebound." Despite the cautious outlook, the company remains focused on delivering strong market outperformance and profitability while investing in critical areas to improve long-term competitiveness.
