1. YC Q2 Earnings: What Happened?

YC announced its Q2 2025 earnings on August 14, 2025. Revenue reached ₩80.4 billion, exceeding the ₩71 billion market consensus by 13%. However, operating profit and net income were ₩4.3 billion and ₩3.5 billion, respectively, falling short of expectations by 61.3% and 71.1%. Essentially, while sales increased, YC’s ability to generate profit significantly declined.

2. Why the Profit Slump?

Several factors could be contributing to the decline in profitability, including increased cost of goods sold, higher SG&A expenses, or unexpected one-time costs. The semiconductor equipment industry is characterized by high fixed costs, which can significantly impact profitability when revenue fluctuates. The semi-annual report suggests overall market downturn and customer inventory adjustments also played a role.

3. What’s Next for YC?

Positive Factors:

  • Growth in the high-performance memory market (HBM, DDR5)
  • Increased investments from key customers like Samsung Electronics and SK Hynix
  • Continued R&D investment

Negative Factors:

  • Potential for continued profit decline
  • Exchange rate volatility and geopolitical risks
  • Uncertainty surrounding new business ventures

4. What Should Investors Do?

Short-Term Outlook: Given the current profit slump, a sell or hold strategy is recommended in the short term.
Mid-to-Long-Term Outlook: If YC presents concrete plans for profit improvement and shows signs of a turnaround, investors can reconsider a buy strategy. Closely monitor Q3 earnings, exchange rate fluctuations, new business performance, and customer investment plans.
