LEGACY FLAT PANEL DISPLAY TESTING EQUIPMENT

The flat panel display (FPD) testing equipment business has transitioned into a low-growth, low-share position within Micronics Japan. Revenue contribution is below 3% of consolidated sales in FY2025 after declining from double-digit percentages in prior decades. Market demand for legacy LCD and traditional FPD testers contracted by approximately -2.0% in 2025, reflecting industry maturation, panel maker consolidation, and migration of production to lower-cost regions. Micronics' relative market share in this segment is estimated at 9%, down from 25-30% historically. Operating margin has compressed to roughly 5.0%, and there are no major CAPEX projects planned; investments are limited to sustaining service and spare parts for the installed base.
