Q1 2026 Preliminary Results: Revenue -65.5% YoY, Operating Profit -87.9% YoY — Hanmi Semiconductor

Summary

Preliminary Q1 2026 consolidated results show a sharp downturn, with revenue falling 38.7% QoQ and 65.5% YoY to KRW 50.9 billion. Operating profit collapsed 87.9% YoY to KRW 8.5 billion, while net income fell 65.2% YoY to KRW 19.0 billion. The pre-tax profit of KRW 25.1 billion held up better than operating profit, suggesting non-operating gains cushioned the bottom line. The steep declines reflect a meaningful slowdown in HBM-related TC bonder demand following the prior year's exceptional peak, and warrant close attention from investors.
