$LITE Transcript from Conference Call: "The thing that keeps me up at night most is: Substrates. Less so sort of reactors and getting the right tools into the fab, although it’s not a zero challenge." They basically went out and said $AXTI is the bottleneck for photonics. Especially if InP substrates keeps $LITE's CEO up at night. I've been mentioning it for the past few months, if AXT they control the substrate supply, they have a lot of pricing power over $LITE to $COHR and America's AI buildout. I've seen a ton of misinterpretation on X saying: "Seven-year agreement with Sumitomo". But they literally said there was supply tightness Today. And the agreement doesn't mean there will be enough supply for 7 years, especially when China export controls start to kick in on upstream feedstock/materials required by Japanese supply chains to make then. This is before Photonics has even started to ramp up. My $AXTI bottleneck thesis is playing out real time and we got new confirmation from $LITE that InP substrates is a bottleneck.
