AI Laser Chip Momentum Builds, But Valuation and Backlog Risks Loom

What happened

Zacks reports Lumentum's AI laser chip business is gaining steam with record EML shipments, surging 200G demand, and expanding co-packaged optics opportunities. However, the latest DeepValue master report maintains a WAIT rating, noting that the stock at $1,030 already prices in a long-duration AI optics scarcity cycle, while the 10-Q explicitly states most customers lack long-term volume commitments and backlog is unreliable. The report highlights ASP erosion in Systems and a crowded narrative, with the next key checkpoint being FQ4'26 results (revenue $960M-$1.01B, non-GAAP op margin 35%-36%) to validate the ramp.

Implication

The positive news flow supports the bull case of sustained AI-driven demand, but the master report's caution about lack of contractual commitments, ASP pressure, and extreme valuation (EV/EBITDA ~760x) warrants patience. A clear catalyst for entry would be FQ4'26 results that meet or exceed guidance, confirming the trajectory. Until then, the risk of a guide-down in a crowded narrative trade outweighs the upside.

Thesis delta

The thesis remains WAIT, as the news of record EML shipments and 200G demand growth aligns with the bull scenario but does not resolve the core concerns of backlog reliability and pricing pressure. The need for observable confirmation from FQ4'26 results is unchanged, despite the positive momentum.
