Q2 2026 Preliminary: Revenue ₩251B (+39% YoY), Operating Profit ₩130B (+51% YoY) — Hanmi Semiconductor

Summary

Hanmi Semiconductor posted preliminary Q2 2026 revenue of KRW 251.2 billion, up 39.5% year-over-year and a dramatic 393.4% quarter-over-quarter, after a very weak Q1 (KRW 50.9 billion). Operating profit surged to KRW 130.3 billion (+51.0% YoY, +1,441.4% QoQ), implying an operating margin of approximately 51.9% — exceptionally high for a capital-equipment and semiconductor-tooling business. The sharp sequential rebound signals a significant demand recovery in Q2. On a first-half cumulative basis, revenue of KRW 302.1 billion is still 7.7% below H1 2025 and cumulative operating profit of KRW 138.8 billion trails H1 2025 by 11.0%, reflecting the drag from the soft Q1. Net income figures were not provided in this preliminary filing; these figures are unaudited and subject to revision.
