Revenue reached $230.57 million, beating the $206.42 million consensus by 11.70% and more than doubling year-over-year at a 103.9% clip, while non-GAAP diluted EPS of $0.49 topped the $0.39 estimate by 25.61%. The outperformance was anchored by broad-based strength across signal conditioning, smart cable module, and switch fabric product lines as new AI platforms entered full production ramps, with Scorpio fabric switch design wins deepening at multiple hyperscaler customers. Management also announced plans to acquire aiXscale Photonics GmbH, positioning the deal as foundational to its next-generation optical connectivity strategy for large-scale AI systems. Looking ahead, the company guided Q4 revenue of $245 million to $253 million, with non-GAAP EPS of approximately $0.51, reflecting continued confidence in PCIe 6 momentum and expanding Taurus Ethernet SCM demand.
