RE: IQE's mcap: $200m. Competitor trades at $3 billion10 Mar 2026 15:09
IQE is the world's largest independent manufacturer of epitaxial wafers — the precision-layered semiconductor wafers that other companies use to make lasers, photodetectors, RF chips, and power devices.
IQE and Landmark are direct competitors at the same level. Both buy substrates from AXT/Sumitomo and sell finished epi-wafers to device makers.
The staggering gap: IQE has 3-4x more production capacity than Landmark but trades at a fraction of Landmark's market cap.
