涉及标的： $AVGO$AXTI$COHR$GOOGL$LITE$MSFT
这是一份关于 $AXTI/中国 在衬底生产和激光级磷化铟方面导致整个 AI 基础设施建设出现单点故障的研究笔记。我并未对个别公司进行估值分析。但如果这一流程中断，$LITE、$COHR、$AVGO 乃至 $GOOGL、$MSFT 都将面临极端的延迟。如果你们感兴趣，我会另写一篇文章关于如何对关键材料瓶颈进行估值。基本上，如果 2024 年的积压订单为 5000 万美元，而总可寻址市场 (TAM) 为 1.5 亿美元。而现在，由于它是关键材料，如果谷歌愿意为此支付 50 倍的溢价（仅为保持生存而增加 BOM 成本的百分之几），那么原本 5000 万美元积压订单的估值逻辑就会转变为未来产能的 25 亿美元。
This is a research note on point failure of the entire AI buildout in $AXTI/China from both substrate production and laser-grade Indium Phosphide. I’m not doing valuation analysis on individual companies But if this flow stops, $LITE, $COHR, $AVGO to $GOOGL, $MSFT faces extreme delays. I’ll write something else about valuing critical material bottlenecks if you want. But basically if a backlog was $50m from 2024 and TAM was $150m. And now because it’s a critical material, if Google would be willing to pay 50 times that (only a few percent increase on BOM cost to stay alive), then the valuation math of that original $50m backlog -> $2.5B for future capacity changes.
