1. LB Semicon’s H1 2025 Results: Key Events

Following the merger with LB Lusem in February 2025, LB Semicon entered the secondary battery materials market. However, the company reported an operating loss of ₩7.3 billion for the first half of 2025. Q2 2025 results were also below expectations, with revenue at ₩115.6 billion (-5% vs. guidance) and operating loss at ₩3.3 billion (-227% vs. guidance).

2. Reasons for Underperformance: What Went Wrong?

LB Semicon’s underperformance stems from a combination of factors, including a sluggish semiconductor market, low utilization rates in the secondary battery recycling segment, and increased merger-related expenses. High customer concentration (A: 32.13%, B: 42.70%) adds to earnings volatility.

3. LB Semicon’s Future: Opportunities and Threats

  • Opportunities: Business diversification through the LB Lusem merger, growing demand for advanced packaging driven by AI and HBM markets.
  • Threats: Intense competition from global OSAT companies, high debt ratio, customer concentration, macroeconomic uncertainty.

4. Investor Action Plan: What Should You Do?

  • Short-term: Closely monitor earnings recovery and progress in stabilizing financial structure.
  • Long-term: Focus on the growth potential of the secondary battery business and the company’s competitiveness in advanced packaging technology. Pay attention to new customer acquisition and overseas expansion strategies.
