Is Toto (WC manufacturer) actually a solid AI-adjacent play, or is it already priced in?

Hey all, long time lurker I came across an interesting angle on (TOTO.T) yes, the luxury bidet company. Apparently, they also manufacture advanced ceramics used to hold silicon wafers during ultra-cold semiconductor fabrication. As AI memory chips get more complex, this type of mterials tech becomes more critical. Some numbers I saw:

~10% of revenue tied to this segment ~40% of operating profit coming from it ~60% up in the last year

The thesis is that while everyone focuses on GPUs, the real edge might be in materials science and semiconductor supply chain niches.

My question: From a fundamentals perspective, does this look like a high-quality, under-the-radar compounder? Or is the AI narrative already fully priced in after the recent run-up?

Would love thoughts on: Margins sustainability Competitive moat in advanced ceramics Valuation vs growth Cyclicality exposure to semis

And last, but not least, is this a clever picks-and-shovels play… or just pure momentum?
