1. What Happened? : Analyzing the Earnings Shock

Jeju Semiconductor reported revenue of KRW 98 billion (standalone basis, +15% YoY) in Q2 2025, maintaining its growth trajectory. However, gross profit margin plummeted to 19.6% compared to 34.8% in the same period last year. Operating income plunged by 61.8%, and net income swung to a significant loss of KRW -350.3 billion. The substantial losses incurred by its subsidiary, Ramsway, are cited as the primary cause.

2. Why Did This Happen? : Understanding the Downturn

The earnings decline is attributed to a combination of factors, including cost pressures across the semiconductor industry, intensifying price competition, and the poor performance of Ramsway. Ramsway’s losses, in particular, have had a devastating impact on Jeju Semiconductor’s consolidated results.

3. What’s Next? : Outlook and Investment Strategies

In the short term, a sharp decline in stock price and dampened investor sentiment are anticipated. However, the mid-to-long-term outlook hinges on the company’s ability to restructure its subsidiaries, enhance the competitiveness of its core products, and diversify its business portfolio. Investors should closely monitor Jeju Semiconductor’s future management strategies and efforts to improve performance.

4. Investor Action Plan

  • Short-term investors: Exercise caution due to increased stock volatility and make prudent investment decisions.
  • Long-term investors: Continuously monitor subsidiary restructuring, earnings improvement progress, and new business performance.
