Q1 2026 Quarterly Report (31st Fiscal Year)
LEENO Industrial filed its Q1 2026 quarterly report covering January 1 to March 31, 2026. Total revenue mix shows IC Test Sockets contributing 64.10% of sales (KRW 63.9 billion, with KRW 59.6 billion from exports and KRW 4.3 billion domestic), while LEENO PINs accounted for 24.65% (KRW 24.6 billion, KRW 18.8 billion exports and KRW 5.8 billion domestic). The company continues to leverage its 40+ years of expertise in semiconductor test consumables and is expanding into medical device components for ultrasound diagnostic equipment. Standard items like company overview, history, capital changes, and share details are omitted per quarterly reporting rules and will appear in semi-annual/annual reports. Strong export-driven revenue concentration in semiconductor test sockets indicates continued tailwind from global memory and non-memory chip testing demand.

Notes

Leeno Industrial is the global leader in pogo-pin style test probes used in semiconductor final test and burn-in, with high market share in non-memory test sockets. Demand is leveraged to advanced packaging and HBM/AI chip test intensity, though high customer concentration in Korean memory makers and Apple/Qualcomm-linked fabless chips is a key risk.

Q1 2026 Preliminary Results: Revenue +27.2% YoY, Operating Profit +35.4% YoY

LEENO Industrial reported strong preliminary Q1 2026 results, with revenue of KRW 99.77 billion, up 27.2% year-over-year and 17.7% quarter-over-quarter. Operating profit jumped 35.4% YoY to KRW 47.30 billion, reflecting an operating margin of approximately 47.4%, indicating robust pricing power and demand for its semiconductor test sockets and probe pins. Net income rose 37.7% YoY to KRW 40.40 billion. The double-digit sequential and YoY growth across all profit lines suggests accelerating demand from advanced semiconductor packaging and HBM-related testing, a positive read-through for the broader Korean semiconductor equipment supply chain.
