JPMorgan Raises Disco Target Price to JPY 83,000, Maintains Neutral Rating

Overview

JPMorgan released an earnings model update report on Japanese semiconductor equipment manufacturer Disco (6146.T). While maintaining a 'Neutral' rating, analysts significantly raised the target price to JPY 83,000 (previously JPY 70,000). This adjustment is primarily based on clients' upward revisions of capacity expectations for HBM (High Bandwidth Memory) and packaging, as well as the company's high market share in grinding and dicing equipment related to generative AI. The report projects a 20% CAGR in operating profit for FY2025-2028, but notes that the currently elevated valuation limits upside potential for a rating upgrade.

Core views

Significant Upward Revision to Earnings Forecasts: JPMorgan updated its earnings model based on the latest developments. For FY2026 (ending March 2026), although sales assumptions related to packaging were slightly lowered (due to minor price assumption adjustments), volume assumptions were increased, resulting in a fine-tuning of the operating profit forecast from JPY 251bn to JPY 245bn (+32% YoY). More notably, for FY2027, reflecting clients' upgraded outlook for HBM and packaging capacity, the operating profit forecast was significantly raised from JPY 276bn to JPY 303bn (+24% YoY). Additionally, FY2028 forecasts were introduced for the first time, with operating profit expected at JPY 321bn (+6% YoY). Technology-Driven Growth Logic: The report emphasizes that medium-to-long-term demand growth from generative AI applications is the core driver. Disco holds an extremely high market share in grinders and dicers used for generative AI applications. Technologically, the firm focuses on near-term opportunities from NAND hybrid bonding and BSPDN (Backside Power Delivery Network), while remaining bullish on the long-term development of PLP (Panel Level Packaging) and HBM hybrid bonding. These technological advancements are expanding the company's Key Knowledge Market (KKM). Valuation vs. Rating Trade-off: Despite the improved earnings outlook, JPMorgan maintains a 'Neutral' rating, primarily due to already high valuations. The new target price of JPY 83,000 is derived from FY2027 EPS estimates and a P/E multiple of approximately 41x. This multiple is about one standard deviation above the company's 10-year historical average P/E (approx. 28x). Analysts believe that assigning a certain valuation premium is justified given the improved growth prospects in the back-end process equipment market, but the current stock price has already priced in most of the positive factors.

Analysis framework

This report employs a typical 'bottom-up' fundamental analysis approach, combining industry cycle assessment with company-specific technology trend analysis. Firstly, revenue drivers (volume and price) are revised by tracking capital expenditure plans and capacity outlooks of downstream customers (such as OSATs and memory chip manufacturers), particularly focusing on the latest developments in HBM and advanced packaging. Secondly, segmented technology market analysis is applied to decompose the company's growth into penetration rate increases and equipment replacement demands across different technology domains (e.g., NAND hybrid bonding, BSPDN, PLP), thereby assessing medium-to-long-term growth potential. Finally, relative valuation (P/E Band) is used for pricing. Analysts compare the currently projected P/E ratio with the company's historical valuation range, determining a reasonable valuation premium level by calculating the historical mean and standard deviation to arrive at the target price. This method accounts for enhanced growth while remaining vigilant against overvaluation risks.

Methodology notes

• Valuation MethodPE/PEG valuation

  Valuation pricing based on historical P/E mean and standard deviation

  The research report uses the company's 10-year average P/E (approx. 28x) as a baseline and adds one standard deviation (reaching approx. 41x) to reflect the valuation premium under high-growth expectations. This is a common relative valuation technique used to judge whether stock prices are overheated during high-prosperity cycles.

• Industry Analysis FrameworkSupply-demand framework

  Downstream capacity expansion transmitting to upstream equipment demand

  The analytical logic follows the industrial chain transmission path: 'Downstream customers (HBM/packaging plants) raise capacity expectations -> Increase CapEx -> Upstream equipment makers (Disco) see order and revenue growth.' This is the core supply-demand logic in semiconductor equipment industry analysis.

• Industry Analysis FrameworkProduct life cycle

  Equipment renewal cycle driven by new technologies (e.g., hybrid bonding)

  The report focuses on the transition of new technologies like NAND hybrid bonding and BSPDN from introduction to growth phases. These technological shifts create demand for new types of grinding/dicing equipment, thereby extending or reshaping the product lifecycle curve.

Asset mapping & comparison

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

• Disco (6146.T)

  Beneficiary: As a global leader in grinding and dicing equipment required for generative AI, directly benefits from HBM and advanced packaging capacity expansion.

  Strengths

  Extremely high market share in critical process equipment; high profit margins; benefits from multiple technology drivers (NAND hybrid bonding, BSPDN, etc.).

  Weaknesses

  Valuation already at historical highs, partially pricing in future growth; capacity expansion could become a bottleneck.

  Comparison

  Compared to peers, it possesses stronger monopoly power in precision processing equipment, but also commands a higher valuation premium.

  Risks

  Slowdown in generative AI demand; semiconductor cycle downturn; loss of market share.

Impact & implications

For Disco, sustained strong demand for HBM and advanced packaging provides high-certainty support for its performance over the next two to three years. However, the market has already largely priced in this high growth (the stock has seen significant YTD gains, and valuation is in the upper range of historical levels). For investors, although fundamentals remain positive, short-term upside may be limited, and caution is warranted regarding valuation correction risks arising from any slowdown in demand growth or macroeconomic recession. The report notes that further expansion of generative AI demand or accelerated growth in the power semiconductor equipment market could present upside surprises; conversely, downside risks exist if the semiconductor sector enters a downturn or if demand recovery for end products (e.g., smartphones) is delayed.

Risks

• Slowdown in generative AI-related demand
• Margin dilution due to product mix shift toward mass production needs
• Semiconductor market entering a downturn
• Reduction in client strategic investments due to severe economic recession
• Delayed recovery in demand for end products such as smartphones
• Loss of market share

What to watch

• Further expansion of generative AI-related demand
• Growth pace of the power semiconductor SPE market
• Whether investment recovery by OSATs and other clients occurs earlier than expected
• Signs of recovery in demand for end products like smartphones
• Progress of the company's capacity expansion plans
• Sales trends of high-margin consumables
