· 供应链分析
$LITE 财报电话会原文： “最让我夜里睡不着的事情是：基板。相比之下，反而没那么担心反应器和把合适的工具装进 fab，虽然这也不是完全没挑战。” 他们基本上是在直接说 $AXTI 是光子领域的瓶颈。 尤其如果 InP 基板会让 $LITE 的 CEO 睡不着觉的话。 我过去几个月一直在提这点：如果 AXT 控制基板供应，它就对 $LITE、$COHR 以及美国 AI 建设拥有很大的定价权。 我在 X 上看到了很多误读，说什么“和住友签了七年协议”。但他们说的明明是现在就已经有供应紧张。而且那份协议也不代表 7 年内供应就一定够，尤其当中国开始对日本供应链制造晶圆所需的上游原料 / 材料实施出口管制时更是如此。 这甚至还没算上光子产业真正开始放量。 我关于 $AXTI 瓶颈的论点正在实时兑现，而 $LITE 又给了我们新的确认：InP 基板就是瓶颈。
$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.
