Analyst View
Lumentum's moat is real but narrow — it's built on technical depth and qualification lock-in, not on scale economics or brand loyalty. The key risk: a motivated, well-funded competitor (Chinese or otherwise) can close the technology gap given 3–4 years. The US manufacturing angle adds a geopolitical durability that the pure technical moat alone doesn't provide.
