TL;DR

LITE (Lumentum) extended its sold-out window from end of 2027 to ALL of 2028. They make the EML lasers that power every 800G and 1.6T optical transceiver going into AI data centers — 50%+ global market share with no alternative supply chain. NVDA already put $2B into LITE with non-cancelable purchase agreements. CEO calls it "the bottleneck right now for the industry."

Key Tickers

Key Takeaways

• LITE is THE bottleneck for AI data center networking. Every 800G and 1.6T optical transceiver needs their EML lasers.
• 50%+ global market share in high-speed EMLs per Bank of America — no near-term alternative supply chain
• NVDA invested $2B in non-cancelable purchase agreements through end of decade — not LOIs, binding commitments
• Sold-out through all of 2028 — demand is exceeding even a 12-fold capacity expansion at their Tokyo factory
• New capex target $100M-$250M — actively scouting additional factory sites in Japan
• CEO quote: "the bottleneck right now for the industry" — this is the kind of supply constraint that drives pricing power

Integration Notes

• LITE is already in our monster scan at +131.6% 3M — this tweet explains WHY it's parabolic
