Amrize Ltd (AMRZ) shares surged 5.10% in pre-market trading on Wednesday, following the release of its third-quarter earnings report late Tuesday. The company's financial results, particularly its revenue performance and improved full-year guidance, appear to have sparked investor enthusiasm.

For the quarter ended September 30, Amrize reported earnings per share (EPS) of $0.98, slightly below the $1.00 reported in the same quarter last year and missing analysts' expectations of $1.02. However, the company's revenue showed significant strength, coming in at $3.68 billion, up from $3.45 billion a year earlier and surpassing the FactSet analyst consensus of $3.49 billion.

Adding to the positive sentiment, Amrize raised its full-year 2025 revenue guidance. The company now expects revenue between $11.7 billion and $12.0 billion, an increase from its previous forecast of $11.4 billion to $11.8 billion. This upward revision aligns with analyst expectations, as FactSet-polled analysts were projecting annual revenue of $11.71 billion. The combination of strong quarterly revenue and an optimistic outlook for the year ahead appears to be driving the stock's pre-market rally.
