ATI Inc's stock soared 5.42% during Tuesday's pre-market session following the release of its fourth-quarter 2025 financial results and forward-looking guidance.

The high-performance materials producer reported adjusted earnings per share of $0.93 for Q4 2025, beating the analyst consensus estimate of $0.88. This represents a 17.7% increase from the $0.79 per share reported in the same period last year. While quarterly revenue of $1.18 billion slightly missed the $1.19 billion estimate, the earnings beat and positive outlook drove investor optimism.

The company also provided Q1 2026 adjusted EPS guidance of $0.83 to $0.89, aligning with analyst expectations. This positive outlook, combined with the Q4 earnings beat, fueled the pre-market rally as investors responded to the company's stronger-than-expected performance and future prospects.
