Lumentum Is Winning AI Stock's Next Big Infrastructure Bottleneck
Lumentum Holdings (LITE) reported fiscal Q4 revenue of $1B, up 109% YoY, with adjusted EPS at $3.23. Guidance for Q1 suggests 134% YoY revenue growth to $1.25B. NVIDIA invested $2B in Lumentum for optical components crucial for AI data centers, highlighting supply-demand imbalances. Analysts predict strong growth but note risks like AI spending slowdowns.
How this was made

The 30-second read
Why it matters
The earnings beat and aggressive guidance suggest a strong demand tailwind, likely prompting a re‑rating by analysts and increased buying pressure.
