Near-monopoly on production-grade T-Glass - the low-CTE / low-dielectric glass cloth that reinforces AI-server IC substrates and high-layer-count PCBs; one of ~three producers worldwide (with Taiwan Glass + Taishan) and dominant on the top tier.
The materials-layer bottleneck of AI chip packaging that almost nobody covers.
2026-08-05 print: Q1 FY3/2027 beat-and-raise - full-year profit guidance lifted (~+15%) to a record-high outlook on strong Special Glass / T-Glass demand. 68% the next session and sits ~56% below its ¥6,580 June high: a sell-the-news de-rate on a crowded, parabolic AI-substrate trade.
Reported fundamentals confirmed the thesis; positioning did not.
- Structural bottleneck, not a fad: T-Glass lines full since H2 2023; top-tier glass $80-100/kg; substrate / PCB makers wait in line. End-demand pulled by $NVDA, $MSFT, $GOOGL, $AMZN; courted by Apple.
- Post-crash valuation reset: ~12.7x trailing earnings, ~35% net margin, ~27% ROE, low-debt balance sheet (~¥341/sh cash) - cheap optics for the growth profile after the -56% de-rate.
- Multi-year scarcity window: the ¥150B Fukushima capacity-triple does not fully relieve supply until 2027-28.
- The bull thesis IS the shortage - and management is actively un-bottlenecking it (¥150B Fukushima triple + Nan Ya handling ~20% of output by 2027). T-Glass de-rates from scarce specialty toward tight commodity once supply catches demand.
No major news in the last 7 days for 3110 - only listicles and opinion pieces, which we filter out by default. .
- Trailing multiple flatters: reported FY26 net (¥41.8B, +225% YoY) carried ~¥37B of one-off items, so true earnings power is lower and the "cheap" trailing P/E overstates the margin of safety even after the Aug 5 raise.
- TSE / JPY name: FX + access friction, one round lot = 100 shares (~$1.8k), no clean public-equity proxy (Nittobo IS the pure-play).
Taxonomy note: belongs in a future "AI Substrate / Glass-Cloth" bottleneck bubble (with Taiwan Glass + the CCL / ABF-substrate names). Mapped to semi-equipment as the closest existing home until that bubble has >=3-4 constituents.
