Indium-phosphide substrate supplier — the upstream wafer that every InP laser diode (every 100G+ datacom transceiver, every 1.6T module of the next cycle) is fabricated on. Q1 26 printed a +80% EPS surprise on +38.7% YoY revenue and the gross-margin inflection (29.9% vs -6.1% YoY) is the kind of operating leverage that confirms a structural tightness. But the stock has rocketed from a 52-week low of $1.38 to an ATH of $134 — a 100x move — and entering at $124 with that history is hazardous. Tier B because the bottleneck is real but the entry is not. AXT is a Beijing-listed-and-headquartered (US ADR) compound-semiconductor wafer supplier — they grow indium-phosphide (InP), gallium-arsenide (GaAs) and germanium boules and slice them into the substrates that III-V foundries pattern. InP is the relevant AI bottleneck: it is the substrate of choice for the high-speed laser diodes that drive 800G, 1.6T and beyond datacom optics. The InP supply chain is genuinely tight — there are only three credible suppliers globally (AXT, Sumitomo Electric, JX Nippon), Chinese InP capacity has been export-controlled, and the AI datacom demand inflection has stripped the safety-stock buffer out of the c…
