  • Microtunanotech: Will HBM Propel its Growth? 2025 Half-Year Earnings Analysis and Investment Strategy

    1. What Happened at Microtunanotech?

    Microtunanotech successfully entered the HBM and AI semiconductor testing markets in the first half of 2025. However, they faced challenges such as slowing sales growth, deteriorating profitability, and increasing inventories. In particular, the widening net loss has amplified investor concerns.

    2. Why These Results?

    Positive Factors:

    • Entry into the HBM and AI semiconductor market
    • Strong presence in the NAND market
    • Continuous R&D investment
    • Solid technological competitiveness and patent portfolio
    • Potential utilization of IPO funds

    Factors to Consider:

    • Deteriorating profitability and widening net loss
    • Slowing sales growth and declining foundry segment sales
    • Increasing inventories and slowing inventory turnover
    • Increasing debt ratio and issuance of convertible bonds
    • Delayed entry into the DRAM market

    Despite the expected recovery of the semiconductor market, intensifying competition and high customer demands remain ongoing challenges for Microtunanotech.

    3. What’s Next?

    In the short term, the stock price is likely to face downward pressure. However, if performance in the HBM and AI semiconductor markets becomes visible, a rebound in the stock price can be expected in the mid to long term. The key is whether profitability improves. It is crucial whether they can achieve a turnaround through sales growth and cost management efficiency.

    4. What Should Investors Do?

    The current investment opinion is ‘Hold’. Closely monitor HBM/AI probe card sales performance, profitability improvement, inventory management efficiency, speed of DRAM market entry, and changes in the macroeconomic and semiconductor industry conditions. It is important to make cautious investment decisions, considering both growth potential and short-term risks.

  • ISC Q2 2025 Earnings: Analyzing the Underperformance and Future Outlook

    ISC Q2 2025 Earnings: A Deeper Dive into the Underperformance

    ISC announced its Q2 2025 earnings on July 30, 2025. While reporting revenue of KRW 51.7 billion (YoY +62%), operating profit of KRW 13.7 billion (YoY +45%), and net income of KRW 11.5 billion (YoY +38%), the company fell short of market projections. Although revenue increased compared to the previous quarter, the growth rate of operating profit and net income slowed down.

    Unraveling the Factors Behind the Earnings Miss

    • Rising Raw Material Prices and Exchange Rate Fluctuations: Increasing prices of raw materials like gold, silicon, and conductive powder, coupled with fluctuations in the KRW/USD and KRW/EUR exchange rates, negatively impacted profitability.
    • Underwhelming Synergy from Post-Processing Business: The initial synergy from the post-processing equipment and materials business acquired in April did not meet expectations.
    • Potential Slowdown in Client Investments: Rising interest rates and bond yields in the US, Europe, and Korea may have dampened client investment sentiment.

    Identifying Opportunities Amidst the Challenges

    Despite short-term headwinds, ISC retains significant growth potential.

    • Leading Position in the AI Semiconductor Market: The continued growth of the AI semiconductor market remains a key driver for ISC’s long-term growth.
    • Growth Potential of the Post-Processing Business: Despite initial setbacks, the post-processing business holds promise for future growth.

    Action Plan for Investors

    Investors should be aware of potential short-term stock price volatility. A long-term investment perspective requires careful monitoring of raw material prices, client investment plans, and the performance of the post-processing business segment.

    Why did ISC’s Q2 2025 earnings fall short of expectations?

    A combination of factors contributed to the underperformance, including rising raw material prices, exchange rate fluctuations, underwhelming synergy from the post-processing business, and a potential slowdown in client investments.

    What is the outlook for ISC?

    The growth of the AI semiconductor market and the potential of the post-processing business are positive factors. However, uncertainties surrounding raw material prices and client investment plans necessitate ongoing monitoring.
