Non-linear revenue upside is real (AI-driven bandwidth intensity plus step-ups from switching systems and new optics architectures), but the current valuation already reflects a large part of that upside. My 5-year case assumes Lumentum grows into the valuation via execution (
backlog conversion, yield/quality, and mix) while the market gradually re-prices it from “scarcity upcycle” toward a more normal high-quality hardware
multiple as supply and competition respond.
