ATI Inc's stock soared 5.12% during intraday trading on Thursday, following the release of better-than-expected first-quarter earnings and an upward revision of the company's full-year outlook.

The high-performance materials maker reported first-quarter adjusted earnings per share of $1.00, significantly exceeding the analyst consensus estimate of $0.88. While revenue of $1.15 billion slightly missed expectations, the strong earnings performance was driven by robust aerospace and defense demand, particularly for commercial jet engine products, along with margin expansion from favorable sales mix and pricing.

ATI raised its full-year 2026 adjusted EPS guidance to a range of $4.20 to $4.48, up from its previous outlook of $3.99 to $4.27, and also increased its adjusted free cash flow forecast. The company attributed the strong results to operational discipline and execution, with adjusted EBITDA climbing 19% year-over-year to $231.7 million.
