1. What Happened? : OI Solutions H1 2025 Performance Analysis

OI Solutions achieved consolidated revenue of KRW 29.9 billion in H1 2025, demonstrating explosive growth of 92.1% YoY. This success can be attributed to strategic expansion into new markets such as FTTH, CATV/MSO, Telecom, and Datacenter. However, operating loss of KRW 9.7 billion and net loss of KRW 10.7 billion highlight the ongoing challenge of improving profitability.

2. Why These Results? : Reasons for Growth and Losses

Key drivers of revenue growth include successful entry into new markets and vertical integration from core optical components to optical transceivers. Conversely, the losses stem from increased investment in new markets, rising R&D expenses, higher labor costs, and low module utilization rate (31.2%).

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

While revenue growth is expected to continue in the short term, profitability improvement may take time. In the long term, OI Solutions is expected to strengthen competitiveness through new market development and technology internalization, benefiting from 5G advancements and next-generation communication technologies. However, rising debt ratio, inventory management, and potential losses from securities holdings pose risks.

4. What Should Investors Do? : Action Plan

OI Solutions holds high growth potential, but short-term profitability remains uncertain. Investors should closely monitor key points like performance in new markets, profitability improvement trends, and tangible R&D outcomes, considering a long-term investment perspective.
