Leeno Industrial
The world's No.1 in IC test sockets and precision pins (Leeno Pin), a consumables-type essential-parts maker with roughly 70% share in wafer test pins. It supplies global customers including Samsung, SK hynix, TSMC and Qualcomm, with IC test sockets at 65.5% of revenue; its top three (anonymized) customers each exceed 10% of sales (KRW 203.1B combined), so customer concentration is a swing factor. Because sockets and pins wear out and are replaced with test volume, recurring demand grows as new-chip and HBM testing rises.

YTD as of 2026-07-10 · source: Yahoo Finance
The world's No.1 in test sockets and pins, a consumables-type essential-parts maker holding ~70% of the wafer test-pin market. Because sockets and pins wear out and are replaced with test volume, rising new-chip and HBM testing translates into recurring demand — the growth logic — and IC test sockets are 65.5% of revenue. Risks are customer concentration (the top three each above 10% of sales) and volatility that swings with test-investment cycles. Upstream on the graph the trigger is test volume at Samsung, SK hynix and TSMC, and this node is the consumables beneficiary of that volume.
