Nikkei 225 · #1 in EUV mask blanks
Hoya Corporation
No advanced chip is made without EUV lithography, and every EUV mask starts as a blank from Hoya (75%+) or AGC — Hoya owns the bottleneck at the very top of the lithography supply chain. Life Care (eyeglass lenses, endoscopes) fills 62% of revenue, but ~60% of profit (pretax JPY 192.3bn, 54% margin) comes from Information Technology, where AI logic capex and data-center HDDs' shift to glass substrates lifted the segment +14% in FY2026 and pushed group pretax profit +26% (JPY 327.7bn). What to watch now: two upside vectors — High-NA EUV and the HAMR glass transition — against the risk that Samsung/S&S Tech localization erodes the oligopoly premium.

Financials & Segments
- Total revenue · Revenue JPY 947.7bn (FY2026 ended Mar 2026, +9.4%); pretax profit JPY 327.7bn (+26.0%); net profit JPY 251.5bn; ROIC 21.1% — a year where Life Care carried revenue and IT drove the profit growth.
- Customer concentration · Profit concentrates in IT's two chokepoints (EUV blanks, HDD glass), with Life Care as the defensive counterweight. The key upside is High-NA EUV (Hoya is the only validated blank vendor) and the early innings of the HAMR glass transition; the key downside is Samsung/S&S Tech localizing blanks and eroding the oligopoly premium.
- Segments · Life Care - eyeglass lenses, contacts (eyecity), endoscopes (Pentax Medical) · Information Technology - mask blanks, HDD glass substrates, imaging
Revenue from
- Toppan (Tekscend Photomask) Medium confidence
Toppan (Tekscend) is a top-tier merchant photomask maker, yet it cannot make a single EUV mask from its own blanks — near-zero-defect blanks come only from the Hoya/AGC duopoly (Hoya EUV 75%+). Hoya thus sits one step further upstream than Toppan as 'the supplier to the mask makers,' owning the true bottleneck where margin accrues as leading-edge mask demand rises.Mentions EN MarketScreener Published Jun 12, 2026: HOYA target price consensus and analyst recommendationsConfirms EN HOYA Corporation Published Apr 30, 2026: HOYA Consolidated Financial Statements for the Year Ended March 31, 2026Mentions KO ETNews Published Jan 12, 2026: Samsung to adopt domestic EUV blank masks (reducing dependence on Japan's Hoya)Mentions EN Semiconductor Insight Published Aug 1, 2025: HOYA expands EUV photomask blank capabilities, strengthening the semiconductor supply chain - Western Digital Medium confidence
To push nearline HDD capacity past 32TB, WD must move to HAMR, and HAMR's 400-450C deposition is too hot for aluminum — glass substrates become mandatory, and Hoya effectively supplies that glass (100% of 2.5"). WD's capacity roadmap therefore is itself a structural demand that lifts Hoya content per drive — not a one-off but a multi-year volume-and-content tailwind tied to data-center storage growth.Confirms EN HOYA Corporation Published Apr 30, 2026: HOYA Consolidated Financial Statements for the Year Ended March 31, 2026Mentions EN Tom's Hardware Published May 15, 2025: HDD components maker Hoya describes 22TB & 24TB hard drives - Photronics Medium confidence
Photronics is the largest independent merchant mask maker but depends on external blanks, so every mask it ships to fabless and smaller foundries without captive mask shops flows directly into upstream Hoya blank demand. For Hoya, the more its customers' customers diversify, the more entrenched its bottleneck position becomes.Confirms EN HOYA Corporation Published Apr 30, 2026: HOYA Consolidated Financial Statements for the Year Ended March 31, 2026Mentions EN Semiconductor Insight Published Aug 1, 2025: HOYA expands EUV photomask blank capabilities, strengthening the semiconductor supply chain - Dai Nippon Printing (DNP) Medium confidence
DNP, which with Toppan anchors the global photomask market, likewise depends on Hoya/AGC for blanks — the essence of Hoya's oligopoly is that however fiercely the mask trio (Toppan, DNP, Photronics) compete downstream, upstream they are all Hoya's customers.Mentions KO ETNews Published Jan 12, 2026: Samsung to adopt domestic EUV blank masks (reducing dependence on Japan's Hoya)Mentions EN Semiconductor Insight Published Aug 1, 2025: HOYA expands EUV photomask blank capabilities, strengthening the semiconductor supply chain - Seagate Technology Medium confidence
Seagate's Mozaic (HAMR) platform cannot exist without glass substrates, and because Seagate long leaned on aluminum and in-house sourcing, its HAMR shift means fresh demand flowing to Hoya glass. With both major HDD makers converting to glass at once, Hoya's HDD line stands at the start of a transition, not at a cyclical trough.Confirms EN HOYA Corporation Published Apr 30, 2026: HOYA Consolidated Financial Statements for the Year Ended March 31, 2026Mentions EN Tom's Hardware Published May 15, 2025: HDD components maker Hoya describes 22TB & 24TB hard drives
Pays to
- Materials (synthetic quartz, low-thermal-expansion glass, Mo/Si sputter targets) Medium confidence
Hoya's vertical integration — it melts its own glass — keeps input-cost exposure low; it procures mainly synthetic quartz/special-glass materials and Mo/Si/Ru sputter targets for EUV multilayers, with quarterly raw-material cost just 12.8% of sales (JPY 31.8bn). That low materials dependence is the moat behind the IT segment's 54% margin.Mentions EN HOYA Corporation Published Apr 30, 2026: HOYA Consolidated Financial Statements for the Year Ended March 31, 2026 - Life Care COGS (lens materials, medical components, distribution) Medium confidence
Life Care's cost base (revenue JPY 590.7bn, +7.2%) is the opposite of IT's — a regulation- and distribution-heavy business with a higher cost ratio but low cyclicality, so the steady cash it throws off acts as the ballast that funds cyclical IT capacity investment and share buybacks.Mentions EN HOYA Corporation Published Apr 30, 2026: HOYA Consolidated Financial Statements for the Year Ended March 31, 2026
Investments
- Centennial Optical (Canada) High confidence
HOYA Vision Care's June 2025 acquisition of Centennial Optical (a Canadian ophthalmic distributor) is not a one-off deal but the execution of a 'Life Care x M&A' strategy — leveraging ~JPY 187.4bn net cash to grow annuity-like revenue in non-cyclical Life Care, a portfolio design meant to offset the swings in cyclical IT earnings.Confirms EN HOYA Vision Care Published Jun 15, 2025: HOYA Vision Care acquires Centennial Optical (Canada)

YTD as of 2026-07-10 · source: Yahoo Finance
Hoya's thesis is a 'bottleneck premium.' Oligopoly in EUV mask blanks (75%+ globally) and 2.5" HDD glass substrates (100%) yields a 54% IT-segment margin, and that segment — 37% of revenue — produces ~60% of group profit. Two growth vectors are both in early innings: AI logic capacity buildout pulling EUV/High-NA blank demand, and nearline HDDs' HAMR transition (WD, Seagate) lifting glass-substrate content per drive. Life Care (62% of revenue) is the low-growth, low-volatility cash source that funds capacity and M&A (e.g., Centennial), cushioning earnings swings. The key risk is a crack in the oligopoly as Samsung adopts S&S Tech's domestic EUV blanks from 2026; the graph exposure is whether Hoya's upstream position over Toppan/DNP/Photronics (blanks) and WD/Seagate (glass) holds.
