Thesis
Disco Corporation (6146.T) is a critical enabler of AI infrastructure, providing precision equipment for advanced semiconductor packaging, including HBM and emerging hybrid bonding/PLP technologies. Strong Q1 performance driven by generative AI underscores its pivotal role in addressing midstream manufacturing bottlenecks. While near-term shipment timing and non-IC weakness present headwinds, long-term AI demand and advanced packaging trends support continued growth. (Updated: 2026-10-23)
Bull case
Continued robust demand for AI accelerators and High-Bandwidth Memory (HBM) is driving significant growth in Disco's IC-related shipments. The company achieved a record high in Q1, primarily fueled by generative AI, with substantial increases in both memory and OSAT segments. This indicates sustained high utilization of advanced packaging capacity, supporting favorable pricing and long-term customer commitments.
Disco is well-positioned for future growth through its progress in advanced packaging technologies like NAND hybrid bonding and Panel Level Packages (PLP). Some customers are already entering mass production for NAND hybrid bonding, and the number of PLP projects is increasing. These emerging technologies are expected to make factories busier in FY2026 and beyond, driving multi-year equipment demand.
Disco's specialized dicing, grinding, and polishing equipment are indispensable for the increasingly complex and precise requirements of advanced semiconductor manufacturing. The need for extremely thin DRAM dies for HBM stacking and reliable separation of semiconductor wafers makes Disco a critical bottleneck solution provider, benefiting from rising production difficulty and limited direct competition.
Bear case
Near-term shipment volatility and timing risks pose a challenge, with a projected large decrease in IC shipments for Q2. This is partly due to projects being pulled forward into Q1 and a reaction to the concentration of generative AI-related shipments. The outlook for the entire second half of the fiscal year, particularly Q4, remains difficult and unstable to forecast.
Weakness in non-IC segments, particularly power semiconductors, continues to be a drag on overall performance. The decline in power semiconductors is significant and is attributed to weak demand in the EV and automotive markets, with no recovery foreseen for Q2. This segment's underperformance offsets some of the strong growth in AI-related areas.
External factors such as foreign exchange rate fluctuations are negatively impacting profitability, with yen appreciation contributing to a lower gross profit margin in Q1 and an expected further decrease in Q2. Additionally, customers are returning to shorter project deadlines and are less willing to issue early purchase orders, suggesting a normalization of demand and potentially increased pricing pressure.
Bull / Bear Case
- Bear Case
- Near-term shipment volatility and timing risks present a significant challenge, with a projected large decrease in IC shipments for Q2 due to projects being pulled forward into Q1 and a concentration of generative AI-related shipments. The outlook for the entire second half of the fiscal year, particularly Q4, remains difficult and unstable to forecast. Persistent weakness in non-IC segments, especially power semiconductors, continues to be a drag on overall performance, attributed to weak demand in the EV and automotive markets, with no recovery foreseen for Q2. Additionally, customers are returning to shorter project deadlines and are less willing to issue early purchase orders, suggesting a normalization of demand and potentially increased pricing pressure. While the yen has weakened recently, the risk of unfavorable foreign exchange rate fluctuations impacting profitability remains a concern, as demonstrated by the Q1 gross profit margin decrease due to yen appreciation.
- Bull Case
- Disco Corporation is strategically positioned to capitalize on the robust and sustained demand for AI accelerators and High-Bandwidth Memory (HBM), which drove record Q1 shipments and is expected to lead to a strong rebound in Q3. The broader semiconductor industry outlook for 2026 forecasts significant growth in memory and AI chips, with AI infrastructure expansion projected to continue through 2029, ensuring multi-year equipment demand. Furthermore, Disco is making significant progress in advanced packaging technologies like NAND hybrid bonding, with some customers entering mass production, and Panel Level Packages (PLP), which are seeing increasing project discussions and are expected to make factories busier in FY2026 and beyond. The company's specialized dicing, grinding, and polishing equipment are indispensable for the increasingly complex and precise requirements of advanced semiconductor manufacturing, benefiting from rising production difficulty and limited direct competition.
- More Compelling & Why
- Bear. Disco Corporation's current trailing P/E ratio of approximately 69.22 is elevated, especially when considering the near-term shipment volatility and the persistent weakness in non-AI segments like power semiconductors. The strongest argument for the bear case is the significant projected Q2 decline in IC shipments and the unstable outlook for H2, which introduces considerable uncertainty against a premium valuation. This valuation appears to fully price in the long-term AI growth without adequately discounting the near-term headwinds and execution risks. My view would flip to bullish if the company demonstrates a clear and sustained rebound in IC shipments in Q3 and beyond, coupled with a stabilization or recovery in the power semiconductor segment, justifying the current growth stock valuation.

| 3 Things Management Is Most Focused On | Call Takeaway & Tone | Prior Quarter'S Y/Y Growth By Segment | 3 Things Analysts Most Pressed On (And Mgmt Responses) | Revenue Segments |
|---|---|---|---|---|
| 3 Things Management Is Most Focused On1. Leveraging Generative AI Demand: Management highlighted the significant increase in ICs, particularly memory and OSAT, driven by generative AI, which led to record-high Q1 shipments. They are focused on capturing this demand, while acknowledging shipment timing fluctuations. 2. Strategic Product Development and Market Penetration: Management is focused on the progress of strategic products like NAND hybrid bonding (entering mass production for some customers), PLP (increasing client discussions), and WMCM (monitoring capacity expansion needs). 3. Monitoring and Adapting to Market Shifts: Management is closely monitoring the recovery of power semiconductors, which are still sluggish due to weak EV and automotive demand, and adapting to the trend of shorter lead times for projects from customers. | Call Takeaway & ToneThe call presented a mixed to cautiously optimistic tone. Management reported record Q1 shipments driven by strong generative AI demand, leading to an upward revision in the full-year forecast. However, they also highlighted a projected Q2 decline in shipments due to timing and a continued slump in power semiconductors. The focus remains on capitalizing on AI-related growth and strategic product development while navigating market uncertainties, shorter customer lead times, and foreign exchange impacts on profitability. | Prior Quarter'S Y/Y Growth By SegmentOverall Net Sales for Q4 FY2024 increased by 55.77% year-over-year. Specific year-over-year growth percentages for individual revenue segments for the prior quarter (Q4 FY2024) were not explicitly provided in the available information. | 3 Things Analysts Most Pressed On (And Mgmt Responses)1. H2 Outlook and Order Trends: Analysts inquired about the direction for H2 (Q3 and Q4) and any changes compared to three months prior. Management responded that forecasting H2 is difficult, but Q3 is expected to be "a little more positive than Q2" due to fluctuating generative AI-related issues and some recovery in other applications like power semiconductors. They also noted a return to shorter project deadlines from customers. 2. Status of Strategic Products: Analysts pressed for updates on specific strategic products such as NAND hybrid bonding, WMCM, and PLPs. Management indicated progress in NAND bonding with some customers entering mass production, increasing project discussions for PLP, and monitoring capacity expansion for WMCM. 3. Profitability (Gross Margin & SG&A) and Generative AI Contribution: Analysts asked about the assumptions for Q2 gross margin and SG&A expenses, and the ratio of generative AI in Q2 shipments and consumables. Management explained that the Q1 gross profit margin decrease was largely due to foreign exchange rates (JPY appreciation), and Q2 is expected to see a further slight decrease due to yen appreciation. SG&A expenses are expected to be around JPY 27 billion for Q2, with performance-linked bonuses being a factor. They stated that specific generative AI ratios for Q2 and consumables are difficult to provide due to internal calculation complexities and shipment fluctuations. | Revenue SegmentsOverall Net Sales for Q1 FY2025 increased by 8.6% year-over-year. Shipments for ICs, primarily driven by generative AI, saw a significant increase and reached a record high for equipment sales as a whole. Non-ICs experienced a decrease, with power semiconductors showing a particularly large decline due to weak demand in EVs and automotive-related products. Shipment value of image sensors and non-semiconductor electronic components also slightly declined. Consumables, specifically SiC consumables, saw a clear year-over-year decrease. |

|---|---|---|---|---|---|---|---|
| About Expanding Eligible MarketThe company is making progress in NAND hybrid bonding, with some customers gradually entering the mass-production phase. The number of projects related to Panel Level Packages (PLP) is increasing, and the company is preparing to capture demand if the PLP market becomes firmly established. Various R&D activities are also underway for other advanced packages. | About CompetitionThere is considerable competition among OSAT (Outsourced Semiconductor Assembly and Test) companies, which can accelerate project preparations and shipments when a memory business is acquired. Customers are no longer intensely competing for equipment, indicating a return to a more traditional business environment without the previous 'overheated feeling'. | About The Broader IndustryThe semiconductor industry is experiencing a clear division, with a significant increase in ICs driven by generative AI, while non-ICs, particularly power semiconductors, are declining due to weak demand for EVs and automobile-related products. The memory market saw a substantial increase in Q1, especially in DRAM, with the ratio of DRAM to NAND being approximately 6:4 or 7:3, a trend influenced by the advent of HBM. The OSAT market is seeing strong performance in both memory and logic segments, including projects for regular smartphones. There's a trend of projects having shorter deadlines, and customers are less willing to issue early purchase orders. | Where Things Are HeadedShipments for ICs are expected to decrease significantly in Q2, partly due to projects being brought forward to Q1 and as a reaction to the concentration of generative AI-related shipments in Q1. A recovery in power semiconductors is not foreseen for Q2. The outlook for H2 is difficult to forecast, with Q3 expected to be slightly more positive than Q2, but Q4 remains unstable. The trend of generative AI-related products is expected to continue for several years, albeit with fluctuations. The company anticipates that PLP and hybrid bonding will contribute to making factories busier in FY2026 and beyond. | Updates On ThemeMidstream | Bullish-Leaning Quotes (Short)The amount was JPY111.1 billion in Q1, which means that we have achieved a record high for a quarter. significant increase in ICs, mainly related to generative AI. the trend of generative AI-related products will continue over a few years. NAND bonding... some customers are gradually entering the mass-production phase. PLP... number of projects we talk about with clients is also increasing. factories busier in FY2026 and onward. | Bearish-Leaning Quotes (Short)amount decreased in non-ICs, showing a clear division between the two. decline was particularly large in power semiconductors. still do not foresee a recovery in power semiconductors in Q2. large decrease in shipments for ICs in Q2, partly due to the advance mentioned earlier and partly as a reaction to the considerable concentration of shipments related to generative AI in Q1. quite difficult to forecast the entire H2. very unstable area regarding Q4. outlook for generative AI in general is difficult to foresee. | HiringThe company is not in a tight situation requiring manufacturing support from headquarters, as was the case during the COVID-19 pandemic. While the slowdown in power semiconductors has impacted some equipment operations, generative AI-related product areas, mainly grinders, have been busy. Overall, the factories have been generally busy. |
