The strong beat and raised guidance, coupled with an early FY2027 outlook of 30%+ growth, confirm the AI-driven demand cycle for optical networking. Traders should watch for continued momentum in cloud provider spending and potential upside to FY2027 guidance when formally issued next quarter. The $2.9B convertible debt refinancing at 0% coupon enhances financial flexibility and supports the growth narrative.
