MORESCO’s Q1 FY2/27 results—and the stock’s 20% limit‑up reaction—offer a useful read on whether AI/DC infrastructure demand is actually fading. Expectations were low (0.88x P/B, small cap ¥22bn), yet the quarter was far stronger than what a “finished” AI trade would imply.

Markets are debating whether hyperscalers are slowing capex. If that were true, MORESCO—whose chemical coatings are used in HDDs for server and storage equipment—would not be posting profits that doubled or tripled. Their Q1 suggests the AI/DC buildout is still flowing through to niche upstream suppliers.

What MORESCO Does

A specialized chemical manufacturer with two pillars: automotive fluids and high‑barrier IT hardware materials. Its most strategic niche is HDD surface lubricants, where it is a major global supplier. Despite SSD adoption in consumer PCs, hyperscale data centers rely heavily on high‑capacity nearline HDDs for cost‑efficient cold/warm storage. As AI training expands dataset sizes, HDD demand rises, lifting MORESCO’s highest‑margin segment.

Q1 FY2/27 (Three Months Ended May 31, 2026)

Revenue grew 9.3%, but operating profit jumped 106% and net profit surged over 200%. The margin expansion reflects a sharp mix shift toward HDD lubricants tied to data center investment.

One caveat: management did not raise full‑year guidance. This may be conservatism rather than a signal of slowing demand, but it tempers how far one should extrapolate Q1 strength.

Conclusion

Large‑cap semiconductor names may be seeing normalization, but MORESCO’s results show that deeper in the supply chain, AI/DC infrastructure demand remains robust. Small, specialized suppliers often reveal the true state of the buildout more clearly than headline names.

The next real catalyst will be hyperscaler earnings later this month. Their AI/DC capex guidance will determine whether MORESCO’s Q1 reflects ongoing strength—or simply the tail end of prior spending.
