The company reported quarterly earnings of $1.74 per share, topping the $1.61 consensus estimate by 7.41%, while revenue rose to $2.05 billion from $1.53 billion a year earlier and came in above the $1.99 billion analyst forecast. Coherent also issued stronger-than-expected first-quarter guidance, projecting adjusted EPS of $1.85 to $2.05 versus the $1.77 analyst estimate and revenue of $2.2 billion to $2.4 billion versus the $2.14 billion consensus. CEO Jim Anderson said fiscal 2026 delivered record revenue, significant margin expansion and non-GAAP EPS growth that was more than twice the pace of revenue growth, adding that the company is entering fiscal 2027 with strong customer demand, expanding production capacity and several new growth platforms starting to ramp.
