Nitto Denko Corporation
6988.TMEDIUMCore · Weight: 6%· Data as of 2026-06-07
Investment Thesis
HOLD — CORRECTED THESIS (prior T-glass attribution was incorrect). Nitto Denko (6988.T) makes semiconductor process tapes and optical films — NOT T-glass (T-glass is made by Nittobo/3110.T, a separate company). Real moat: (1) NF735 plasma dicing tape for HBM + 2.5D/3D chip packaging at TSMC and Samsung — direct AI infrastructure exposure; (2) IBM JDA (Sep 2025) for advanced chiplet packaging polymeric materials — R&D-stage upside; (3) Dominant OLED/LCD polarizing films (~71% global oligopoly with Sumitomo Chemical + LG Chem) for Apple/Samsung. FY2025 (ended Mar 2026): Revenue ¥1,028.2B (+1.4%), OP ¥183.6B (-1.1%), NI ¥133.5B, FCF ¥84.7B. FY2027 guidance: Revenue ¥1,065B (+3.6%), OP ¥193B (+5.1%). Dividend raised ¥60→¥64. Valuation attractive: Forward PE 11.35x, P/B ~2.0x, Morningstar fair value ~¥5,179 vs market ~¥3,115.
Risk
1) CHINA EXPORT CONTROL RISK: On China watch list for export controls. Asia-Pacific ~60% of revenue. Formal restrictions on semiconductor tape exports to Chinese chipmakers would be a material negative. HIGH severity. 2) ROE below target: 12.2% vs 15% company target; FCF declined ¥102.8B→¥84.7B YoY — capex rising. 3) LCD polarizer margin compression: Chinese competitors (Shengbo) scaling aggressively. Apple exploring polarizer-free OLED (long-term). 4) Optronics segment headwind: LCD polarizer pricing pressure continues; OLED shift helps but slower. 5) Note: Prior thesis citing T-glass has been CORRECTED — actual thesis is semiconductor process tapes.
Monitoring Trigger
UPGRADE trigger: If semiconductor tape revenue (within Optronics segment) exceeds 25% of total OR IBM JDA produces commercial product announcement — ADD to 8%. TRIM trigger: China formally restricts Nitto semiconductor material exports → EXIT (downside >20%). WATCH: ROE recovery toward 15% target — if fails for 3+ consecutive quarters, reassess position.

Initial DD
CRITICAL CORRECTION: T-glass thesis was wrong — Nittobo (3110.T) makes T-glass, not Nitto Denko (6988.T). Thesis corrected to semiconductor process tapes (NF735 for HBM/2.5D/3D) + optical films + IBM JDA. FY2025: Rev ¥1,028.2B (+1.4%), OP ¥183.6B (-1.1%), FCF ¥84.7B, div raised ¥60→¥64. FY2027 guidance Rev ¥1,065B. Supply chain expanded to 5 entries.

|---|---|---|---|
| confirmed | Apple | Optical polarizing films (NPF) for iPhone/iPad OLED/LCD displays | Nitto Denko on Apple renewable energy supplier commitment list. Top-3 global polarizer maker (~71% oligopoly share with Sumitomo Chemical + LG Chem). Primary film for Apple iPhone displays.[source](2025-ongoing) |
| confirmed | IBM Research (Albany NanoTech) | Polymeric materials for advanced chiplet packaging (warpage, thermal, crosstalk) | JDA signed September 9, 2025. Focus: materials for warpage reduction, thermal management, crosstalk suppression in AI chiplet packages. Commercial upside if R&D succeeds.[source](2025-09-09) |
| probable | Samsung (HBM + Pyeongtaek) | NF735 plasma dicing tape for HBM3/HBM3E and 2.5D/3D packaging | NF735 series launched May 2024 for HBM and 2.5D/3D applications. Samsung Pyeongtaek produces HBM for Nvidia AI GPUs. Volume production at this node cited in secondary sources. Not confirmed by primary Nitto/Samsung PR.[source](2024-present) |
| probable | TSMC | Dicing tapes, back-grinding tapes, DAF films for advanced node backend processes | Nitto holds oligopoly position in wafer process tapes. NF735 plasma dicing tape reportedly in use at selected TSMC backend lines. TSMC is the world's largest advanced chip foundry.[source](2024-present) |
| probable | Samsung Display | Optical polarizing films (circular polarizers, retardation films) for OLED panels | Samsung Display is the world's largest OLED producer. Nitto is a leading circular polarizer film supplier. Not confirmed by direct named PR.[source](ongoing) |
