1. DI Corp Q2 2025 Performance: What Happened?

DI Corp reported revenue of KRW 119.2 billion (+8% YoY), operating profit of KRW 12.2 billion (+23% YoY), and net profit of KRW 8.8 billion (+21% YoY), surpassing market projections. This strong performance was primarily driven by the booming semiconductor equipment division, fueled by the expanding DDR5/HBM market.

2. Why the Surge in Performance?

The semiconductor equipment division achieved remarkable results with KRW 229.3 billion in revenue and KRW 22.2 billion in operating profit. This represents a 183.6% YoY increase in revenue and a return to profitability. The growth is attributed to the surging demand for HBM and DDR5, driven by the AI and high-performance computing markets. DI Corp’s successful launch of Korea’s first HBM wafer tester solidified its market leadership. Their dominant 44% market share in the Burn-In Board market further strengthens their position.

3. Despite the Success, What are the Risks?

  • Struggling Other Divisions: The electronics and audio/visual divisions underperformed, raising concerns about profitability and the need for improvement.
  • Exit from the 2nd Battery Business: The decision to withdraw from the secondary battery market due to unfavorable market conditions raises questions about future growth drivers.
  • Financial Risks: The increasing debt ratio and exposure to exchange rate/interest rate fluctuations warrant careful consideration by investors.

4. What Should Investors Do?

While DI Corp’s robust growth in the semiconductor equipment sector provides positive momentum, investors should not overlook the underperforming divisions and financial risks. Careful monitoring of the company’s restructuring efforts and new business development is crucial for informed investment decisions.
