Photronics' real story is node migration showing up in its mask mix, not its FX-flattered EPS beat. High-end IC masks, 28nm and smaller, rose 28% to $68.5M while mainstream masks fell 9%, lifting high-end to a record 44% of IC revenue; it is the only high-end-capable commercial mask maker in the US. Heavier capex in Allen, Texas and Korea will hit margins first as depreciation. If high-end holds above 44% next quarter, the shift is a trend; a drop toward the high 30s would make it catch-up. x.com
