Demand cascade: GPU compute → optical bandwidth → transceivers → InP substrates
The market discovered the GPU layer first (NVDA). Then the networking layer (AVGO, MRVL). Then the transceiver layer (LITE re-rating from telecom to AI infra). AXTI is the next layer down — the substrate underneath the transceiver. Same demand driver, less analyst coverage, 4x move in 3 months but analyst PTs ($28-35) still lag the stock ($48.86). Either the Street is behind or the stock is ahead. The InP capacity doubling in 2026 is the key variable.
All InP manufacturing is in China. US export licenses required for shipments. Q4 2025 revenue dropped from $28M to $23M due to permit delays. A single batch delay = missed quarter. Escalation of US-China tensions could add InP to stricter control lists. This is binary risk that doesn't correlate with demand.
