1. What Happened?

On August 20, 2025, a pre-market after-hours block trade saw 450,000 shares of KOSES, totaling ₩5.1 billion, change hands. The purchase by other corporations and the sale by foreign investors are open to various interpretations.

2. Why Did This Happen?

After-hours block trades often reflect large capital movements or strategic decisions by specific investors rather than fundamental changes in a company. It’s difficult to determine whether this transaction relates to KOSES’s business report amendment (regarding the supply contract with Enovix Corporation for secondary battery equipment) or simply profit-taking. The recent growth of the secondary battery market and KOSES’s contract with Enovix are positive factors, but the poor performance in 2024 remains a concern.

3. What’s Next?

In the short term, purchases by other corporations could positively impact the stock price, but the poor 2024 performance and market uncertainties could exert downward pressure. In the long term, the growth of the secondary battery business, the fulfillment of the Enovix contract, and improvements in profitability will determine the stock’s direction. The rise in the KRW/USD exchange rate could be positive for USD-based sales.

4. What Should Investors Do?

  • Avoid being swayed by short-term price fluctuations and focus on KOSES’s fundamentals and growth potential.
  • Continuously monitor the progress of the Enovix contract, the achievement of 2025 earnings forecasts, and efforts to improve performance in the semiconductor business segment.
  • Be mindful of risk factors such as intensifying competition in the secondary battery market, investment fluctuations by major clients, and fluctuations in exchange rates and the macroeconomic environment.
