Disclosure Type: Provisional Earnings Release (Consolidated Financial Statements)

💡 3-Second Summary

JUSUNG ENGINEERING’s operating profit for the first quarter of 2025 surged by 382.3% year-on-year to KRW 33.9 billion, delivering a massive earnings surprise that far exceeded market estimates. On a quarter-on-quarter basis, operating profit rocketed by 1,655.1%, signaling a powerful and definitive financial turnaround.

📊 1. [Summary of Core Disclosure Content & Major Figures]

  • Revenue (Q1): KRW 120,846 million (+11.6% QoQ, +113.6% YoY)
  • Operating Profit (Q1): KRW 33,908 million (+1,655.1% QoQ, +382.3% YoY)
  • Profit Before Income Tax (Q1): KRW 34,895 million (+23.2% QoQ, +154.6% YoY)
  • Net Income (Q1): KRW 27,716 million (+25.7% QoQ, +72.3% YoY)
  • Revenue by Business Segment for Q1:
    • Semiconductor Segment: KRW 120,003 million (Accounting for 99.3% of total quarterly revenue, driving growth)
    • Solar & Display Segment: KRW 843 million

📈 2. [Expert Insight: Assessment of Impact on Stock Price]

  • Short-term Impact (Strong Upward Price Catalyst): This scorecard, showing a more than twofold increase in revenue and an operating profit surge of nearly 4.8 times YoY, will act as a powerful near-term bullish driver. Crucially, the vertical spike from a mere KRW 1.9 billion in Q4 2024 to KRW 33.9 billion in Q1 demonstrates that the temporary gap in revenue recognition has completely concluded.
  • Mid-to-Long-term Fundamentals: While these are preliminary figures pending final external verification, the velocity of this financial turnaround is undeniable. Shipment of flagship Atomic Layer Deposition (ALD) equipment brought in KRW 120 billion, effectively dominating the corporate mix. This serves as solid fundamental proof that tool integration for advanced global memory migration is hitting its stride.
  • Financial Viewpoint: The company displayed a textbook operational leverage effect, where the operating profit growth rate (+382.3%) significantly outpaced the top-line growth rate (+113.6%). As fixed manufacturing overheads were heavily diluted by scaled output, this indicates a structural upgrade in the firm’s fundamental profitability margins.
