AGC's medium- to long-term growth opportunities in semiconductor materials are expanding, while the PTFE versus low-dielectric glass debate still awaits test results for confirmation

Overview

This report is an event commentary by J.P.Morgan's Japan equity research team on AGC's semiconductor-related business briefing. AGC held a semiconductor business briefing after the market close on June 2, emphasizing targets of about ¥100bn in semiconductor-related revenue for FY2025 and about ¥200bn for FY2030. The report believes AGC's medium- to long-term opportunities in semiconductor materials are expanding, with growth driven jointly by EUV mask blanks and CCL in Electronics, as well as process materials and fluorinated products in Performance Chemicals.

Core views

The core view is that AGC's semiconductor materials business not only has room for revenue growth, but may also contribute more significantly to overall profit than revenue growth alone due to high barriers to entry. In the Electronics segment, EUV mask blanks benefit from recovery at key customers and an expanding customer base, while the new ELL Series of CCL improves performance through a combination of internally developed resin and glass cloth. In the Performance Chemicals segment, high-barrier products such as FFKM, ETFE, CYTOP, and PTFE benefit from rising deposition and etch intensity. Regarding the PTFE versus low-dielectric glass debate, the report believes M10 deserves close attention because it combines electrical characteristics close to PTFE with better compatibility for board manufacturers, but the final choice remains undecided.

Analysis framework

The report uses an event commentary approach, summarizing the revenue targets, segment structure, product line progress, and industry chain material substitution debate disclosed in AGC's business briefing, while also evaluating the medium- to long-term opportunities and uncertainties in AGC's semiconductor materials business in light of the stock price reaction on the day, WFE demand expectations, and the testing timeline for backplane materials.

Methodology notes

• Event interpretationSummary of key points from the company business briefing

  Assess AGC's semiconductor business outlook based on revenue targets, segment drivers, product technology barriers, and industry demand assumptions.

  The report does not provide a new valuation model, but instead forms a positive view of the company's semiconductor materials business based on AGC management's briefing, product portfolio, and industry demand signals.

• Industry chain material comparisonComparison of PTFE and low-dielectric glass

  Compare the potential substitution relationship among PTFE, M9/M10 specification materials, and Low-Dk glass in backplane applications.

  The report believes the likelihood of adopting M9 has declined while M10 testing has accelerated; M10 has electrical characteristics close to PTFE and better compatibility with board manufacturers, but the final decision is expected only after testing concludes around August.

Asset mapping & comparison

Structured mapping from thesis to named assets (strengths, weaknesses, peers, risks).

• AGC (5201.T)

  Core subject of the report, with exposure to semiconductor materials and PTFE.

  Strengths

  Its product portfolio, including EUV mask blanks, CCL, FFKM, ETFE, CYTOP, and PTFE, has technical barriers; the semiconductor-related revenue target increases from about ¥100bn in FY2025 to about ¥200bn in FY2030.

  Weaknesses

  Details of part of Performance Chemicals revenue have not been disclosed; PTFE remains in the development and testing stage for backplane applications.

  Comparison

  After market discussion that PTFE could replace low-dielectric glass, AGC's stock rose 9% on the day, significantly outperforming a flat TOPIX.

  Risks

  The final material route remains undecided; if PTFE is not adopted or if back-end process materials scale more slowly than expected, revenue upside may be limited.

• Nittobo (3110.T)

  Comparable name related to low-dielectric glass Low-Dk2.

  Strengths

  Has exposure to low-dielectric glass.

  Weaknesses

  If the market shifts toward PTFE or other substitute materials, expectations for low-dielectric glass could come under pressure.

  Comparison

  On the day discussion of PTFE substitution intensified, Nittobo's stock fell about 10%.

  Risks

  The final adoption outcome for M10, PTFE, and Low-Dk glass still depends on testing and compatibility with board manufacturers.

• Nippon Electric Glass (5214.T)

  Comparable name related to low-dielectric glass Low-Dk2.

  Strengths

  Has exposure to low-dielectric glass.

  Weaknesses

  Short-term market sentiment is affected by the possibility of PTFE substitution.

  Comparison

  On the day discussion of PTFE substitution intensified, Nippon Electric Glass's stock fell about 10%.

  Risks

  If backplane material specifications shift toward solutions closer to PTFE characteristics, related low-dielectric glass exposure may face pressure on valuation and order expectations.

Key data

• Semiconductor-related revenue targetAbout ¥100bn in FY2025 and about ¥200bn in FY2030The company target implies about 15% CAGR and roughly doubling every five years.
• Historical revenue baselineAbout ¥50bn in FY2020 and about ¥100bn in FY2025The report states that AGC's semiconductor-related revenue has increased from about ¥50bn in FY2020 to about ¥100bn in FY2025.
• Current revenue mixAbout 65% from Electronics, with the remainder from Performance ChemicalsManagement plans for revenue in both segments to double over the next five years.
• EUV mask blanks salesMore than ¥40bn in FY2024, with FY2026 likely to set a new record highDriven by recovery at key customers and a broader customer base.
• WFE demand assumptionThe WFE market is expected to grow about 20% YoY or more in 2026-2027Rising deposition and etch intensity may cause demand growth for related equipment to outpace the overall WFE market.
• Same-day market reactionAGC rose 9%, while Nittobo and Nippon Electric Glass both fell about 10%, and TOPIX was flatReflecting changes in market expectations that PTFE may replace low-dielectric glass.
• Timing of material selectionThe final decision is expected to become clearer after around AugustThe report says ongoing testing may end around August.

Impact & implications

From an investment perspective, AGC is positioned as a beneficiary of expanding medium- to long-term growth opportunities in semiconductor materials, especially in EUV mask blanks, CCL, and high-barrier fluorinated materials. If back-end process materials such as glass core, co-packaged optics, and glass interposers scale up earlier than expected, AGC's five-year revenue doubling plan may have upside; however, the technical path among PTFE, M10, and low-dielectric glass has not yet been finalized, so the short-term stock price reaction may reflect substitution expectations more than confirmed orders.

Risks

• The final material choice among PTFE, M10, and Low-Dk glass for the Rubin Ultra backplane has not been determined and is expected to await test results around August.
• AGC's plan to double semiconductor revenue depends on simultaneous expansion of EUV mask blanks, CCL, and Performance Chemicals; if customer recovery or adoption of new applications is slower than expected, the growth pace may slow.
• The assumption that the WFE market will grow about 20% YoY or more in 2026-2027 is a key industry assumption; if semiconductor capital spending comes in below expectations, demand for process materials may be pressured.
• Disclosure on the revenue contribution details of Performance Chemicals sub-products such as FFKM is limited, creating a risk of insufficient information when assessing earnings elasticity.

What to watch

• The route choice among PTFE, M10, and Low-Dk glass after backplane material testing ends around August.
• Whether AGC's EUV mask blanks in FY2026 will surpass the FY2024 sales high of more than ¥40bn as expected.
• Customer adoption progress of AGC's new ELL Series CCL in 224G switch and router applications.
• Whether back-end process materials such as glass core, co-packaged optics, and glass interposers scale up earlier than expected.
• WFE market growth in 2026-2027 and the strength of demand for deposition and etch equipment.
