Test consumables · World No.1 in test sockets & pins
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 2026-09-04 · source: Yahoo Finance
Leeno Industrial operates across KOSDAQ, Test consumables, World No.1 in test sockets & pins. After +150.1% in 2025, it gave back -37.1% in 2026. The demand side (avg +45.9%) leads the stock (-37.1%), so customer moves come first here. Among connected nodes the furthest ahead is SK hynix (+81.6%) and the furthest behind is Qualcomm (+0.2%). If chain logic explains the gap, the laggard is the next propagation candidate; if not, the link itself deserves a second look. Because sockets and pins wear out and are replaced with test volume, recurring demand grows as new-chip and HBM testing rises.
