Lumentum's FY2026 revenue soars 83%, driven by AI data center optical tech demand.

Lumentum Holdings Inc. reported a strong FY2026 with revenue reaching $3.01 billion, up 83.2% year-over-year, and Q4 revenue doubling to $1.006 billion. The company is shifting from telecom equipment to becoming a key supplier of optical components for AI-driven data centers, including lasers and photonic circuits. This growth is fueled by rising demand for AI cluster technologies, making Lumentum's products increasingly essential. Despite a headline accounting loss, the company trades at a low valuation relative to its earnings growth, presenting a buy opportunity for investors.
