Soulbrain's thesis is 'a materials bottleneck riding the memory and leading-edge cycle.' With 70-100% domestic share in HF and phosphoric-acid etchants, it is effectively the sole supplier of core process materials to Samsung (3nm GAA etchant) and SK hynix (high-purity HF for HBM/3D NAND) — and because materials are consumable, revenue is recurring in proportion to fab utilization. The +193% in 2025 came from the HBM and leading-edge boom, and the -36% give-back in 2026 is a correction of that pre-pricing. The upside is structural: as processes grow more complex (3D NAND layer stacking, GAA), etch/clean steps multiply and material volumes rise; the downside variables are high-purity feedstock (HF, phosphoric acid) sourcing and concentration on Samsung/SK.
