AXTI · AXT, Inc.

AI capex projected to reach $3-4 trillion annually by 2030, benefiting companies controlling key AI supply chain nodes like photonics, lasers, epiwafers, neoclouds, and memory.

Share issuance considered predatory; plan to sell all AXTI positions if it passes.

AXTI is a quasi-monopoly in a critical AI supply chain material, now on White House shortage list and highlighted in US-China trade talks.

InP substrate shortage is a bottleneck for AI infrastructure, making AXT a key upstream chokepoint benefiting from photonics ramp.

Nippon Chemical Industries is a critical supplier of red phosphorus for InP substrates used in photonics for AI, posing a single point of failure risk.

Highlighting risks to hyperscalers' AI capex due to debt, potential rate cut delays, and supply chain disruptions from geopolitical tensions, as well as broader vulnerability of US AI and robotics programs due to reliance on China and Russia for rare earths and critical materials.

Multiple semiconductor material companies with unique bottlenecks/monopolies offer asymmetric upside: LPKFF (glass substrates, laser etching, low MC), MTRN (Beryllium monopoly), LPTH (multi-sector bottleneck), AXTI (InP bottleneck in AI).

Export restrictions on AXTI pose threat to US AI buildout; hyperscalers need 3 years to engineer around, so dependency remains.

Supply chain bottleneck in China-based substrate production and laser-grade Indium Phosphide (AXTI) could cause extreme delays in AI buildout, making capacity extremely valuable. Valuation math suggests backlog could be worth multiples if material becomes critical.

Coherent ($COHR) faces supply chain risk: it depends on merchant market for 6N InP polycrystal feedstock; if suppliers like Vital Materials or $AXTI cut off, its laser/transceiver business halts, bottlenecking hyperscaler buildout.

AXTI faces significant risk due to low valuation despite being a critical AI supply chain supplier

Equity dilution from float doubling poses significant risk to AXTI and IREN shareholders.

AXTI benefits from a supply bottleneck in InP substrates and feedstock for hyperscalers, making traditional valuation metrics (P/S, P/E) irrelevant.

Points out a supply chain bottleneck for AXTI related to InP substrates from China and supplier dependencies.

Japanese export controls on InP substrates threaten photonics supply chain, potentially straining LITE and others, but AXTI capacity expansion and pricing premiums could offset.

Photonic supply chain bottlenecks represent an investment opportunity similar to HBM bottlenecks, as hyperscalers hoard materials and acquire capacity. Focus on vertically integrated players like AXTI and upstream suppliers like Sumitomo and Dowa.

The 2026 photonics supercycle and most upstream bottleneck thesis is playing out as AXT hits $100+ even amid a 10% drop.
