  • Yesti IR Analysis: Will HBM Propel its Growth? 2025 Second Half Investment Strategy

    Yesti IR: What Happened?

    On August 26, 2025, Yesti presented its 2025 H1 earnings and updates on high-pressure annealing equipment and HBM-related equipment promotions. While semiconductor equipment sales increased by 45% YoY, overall revenue slightly decreased, and operating profit significantly declined.

    Why the Sluggish Performance?

    The decline in revenue and operating profit is primarily attributed to the slowdown in the display market, increased cost of goods sold, and higher R&D expenses. The possibility of decreased sales from a major client (Company A) further fuels concerns about future performance.

    What’s Next for Yesti?

    The growing demand for HBM and other AI chips presents a significant opportunity for Yesti. However, the company must address challenges related to its struggling display business and declining profitability. The equipment promotion updates and future strategies announced during the IR are crucial for investors.

    • Positive Factors: HBM market growth, technological competitiveness, and potential for overseas expansion
    • Negative Factors: Continued weakness in the display business, declining profitability, and macroeconomic uncertainties

    Investor Action Plan

    Carefully analyze the IR presentation and develop investment strategies from both short-term and long-term perspectives.

    • Short-term Investors: Be mindful of potential stock price volatility following the IR announcements. Prepare for both positive and negative scenarios.
    • Long-term Investors: Continuously monitor HBM market growth, Yesti’s technological competitiveness, potential for overseas expansion, and the success of its component internalization strategy. Pay close attention to changes in macroeconomic indicators.

    Effective risk management requires ongoing monitoring of risk factors, including the display business, profitability, and potential dilution effects.

    Frequently Asked Questions

    What is Yesti’s main business?

    Yesti manufactures semiconductor/display heat treatment and pressure process equipment, semiconductor process infrastructure components, and process components.

    What were the key takeaways from the IR?

    The key takeaways were the announcement of the 2025 H1 earnings and updates on high-pressure annealing equipment and HBM-related equipment promotions.

    What is the outlook for Yesti?

    Yesti is expected to benefit from the growth of the AI chip market, but faces challenges related to improving profitability and overcoming weakness in the display business.

  • ISC (095340) Semi-Annual Report Analysis: Q2 Earnings Miss Despite AI Chip Boom, Investment Strategy?

    What Happened? ISC Q2 Earnings Miss Market Expectations

    ISC announced its preliminary Q2 2025 earnings on August 14, 2025. Revenue, operating profit, and net profit all fell short of market consensus, posing a potential short-term negative impact on the stock price.

    Why the Underperformance? Slowdown in the General Memory Market

    The sluggish performance is linked to the slowdown in the general memory market. However, there are positive aspects. Q2 earnings grew by more than 50% compared to the previous quarter, and the growth of the AI semiconductor market still presents a significant opportunity for ISC.

    So, What Should Investors Do? Maintain ‘Buy’ Rating with a Mid-to-Long-Term Perspective

    Despite the short-term setback, ISC’s core competitiveness and potential benefits from the AI chip market growth make it an attractive investment in the mid-to-long term. Its dominant market share (90%) in the silicon socket sector and diversification through new business ventures support a positive outlook. The low debt-to-equity ratio (15.67%) also ensures financial stability.

    Investor Action Plan: Careful Monitoring and Risk Management are Essential

    • Maintain Buy (Mid-to-Long Term): Considering the AI semiconductor market growth and the potential of new businesses, maintain a buy rating with a mid-to-long-term perspective.
    • Risk Management: Monitor macroeconomic and industry risks, including interest rate fluctuations, exchange rate volatility, and intensified competition in the semiconductor market.
    • Monitor New Businesses: Closely watch for synergy with acquired companies and the materialization of tangible results.
    • Observe Earnings Trends: Check whether the company recovers its growth momentum in the coming quarters.

    Frequently Asked Questions

    What is ISC’s main business?

    ISC manufactures silicon sockets, essential components for testing semiconductor chips. They hold a leading position in the AI semiconductor test socket market with world-class technology and a 90% market share.

    Why were ISC’s Q2 earnings lower than expected?

    The slowdown in the general memory market impacted ISC’s performance. However, the growth of the AI semiconductor market remains a substantial opportunity.

    Should I invest in ISC?

    Despite the short-term underperformance, ISC remains an attractive investment from a mid-to-long-term perspective, given the potential benefits from AI market growth and new business expansions. However, investors should carefully consider risk factors such as interest rate fluctuations, exchange rate volatility, and intensified competition in the semiconductor market before making investment decisions.
