They are spending $74M a quarter to build capacity they effectively already sold out through 2025.
Thesis: Lumentum controls the scarcity in the AI optical supply chain: 200G EMLs. While the street frets over the delay in vertical integration, the reality is bullish—internal capacity is so valuable they are choosing to sell it at a premium rather than consume it for their own transceivers. The margin expansion story isn't broken; it's just shifting from 'integration efficiency' to 'pricing power' on the component side. With a third hyperscaler locked and capacity on allocation through 2025, the volume ramp is de-risked.
Verdict: LONG — Conviction: HIGH
Catalyst: Q2/Q3 margin inflection as EML pricing power flows through the P&L, followed by the Thailand facility ramp hitting full utilization in mid-2025.
Key Risk: Execution failure on the Thailand cleanroom buildout or indium phosphide yield issues on the new 200G products could cap revenue despite demand.
The Tell: When asked why vertical integration was delayed, Lowe admitted: 'It makes more sense for us to buy those CW lasers and free up that EML capacity to ship to our customers.' They are literally too profitable/constrained on chips to use them in their own modules right now.
Friction Level: MODERATE_FRICTION — Bears see a capex hole and a capacity ceiling; Bulls see a scarcity premium and a locked-in revenue ramp to $500M.
