Recent news highlights significant silicon photonics orders and a strategic pivot toward AI infrastructure, driving investor optimism despite insider selling activity.
Outlook remains growth-focused with FY27 revenue guidance of 160-200% expansion, though high valuation (P/S 65.13) and customer concentration pose risks. Analyst consensus leans neutral with 33% buy ratings, while technical indicators suggest near-term support at $97 with resistance at $107. The stock's AI-driven backlog expansion supports bullish sentiment despite current negative cash flow.

Revenue grew to $4.01B in 2025, with a net income margin of 20.25%, though valuation multiples remain elevated with a P/E of 273.32.
The outlook is positive due to AI-driven growth in licensing and royalties, with management targeting $25B revenue by FY31.
