Shared metric table

Live market metrics plus reported quarterly revenue and profit QoQ rows.

Green and red only apply where direction is meaningful. Quarterly revenue and profit cells inherit the sign of the reported QoQ change, which can swing sharply when the prior quarter included a one-time item.

AI datacenter optics

Why it could benefit

  • Optical interconnect is becoming a bigger AI datacenter constraint as cluster size and bandwidth rise.
  • Lumentum adds exposure to the photonics layer rather than just the switch or accelerator.
  • That makes it useful if the next wave of AI bottlenecks shifts from compute to connectivity and optics.

Moat / edge

  • Photonics and optical-component expertise in a demanding market.
  • Positioning in a layer of the stack that becomes harder to ignore as systems scale.
  • Strategic relevance if large AI platforms push harder into optical networking.

What to watch

  • Cloud and AI optics demand versus telecom weakness.
  • Product mix and margin recovery.
  • How quickly optical buildouts become material in AI infrastructure.

Key risks

  • Optics can still be timing-sensitive and program-dependent.
  • The company has other end markets that can muddy the AI signal.
