Photronics vs US Dollar/Korean Won FX Spot Rate: why the prices moved differently

• ▲

  Q3 beat shows core business still growing Photronics reported fiscal Q3 revenue of $216 million and adjusted earnings of $0.50 per share, both above analyst expectations. High-end IC work hit a record 44% of IC revenue, showing demand for advanced photomasks remains strong. This is the main reason the stock jumped 27% before fading.

  The Q3 earnings beat is the biggest new positive force behind PLAB's move this period.

• ▼

  Design-release delays and geopolitics widen Q4 guidance Management guided Q4 revenue to a wide $207-$227 million range, citing product delays, high fab usage, memory costs, and geopolitical uncertainty slowing design releases. The midpoint is barely above last year, and the high end of EPS guidance is below Q4 2025. This uncertainty is why the initial 27% gain faded to about 4%.

  The wide, soft Q4 guidance is the key new negative that capped the stock's rally.

  Tech-driven capital inflows and exporter dollar selling lift the won South Korea's won has been the best-performing Asian currency, gaining over 9% this quarter, as tech-related capital inflows and exporters converting dollar revenues (including SK Hynix's $26.5B repatriation) boosted demand for the won.

  Retail investors buy US stocks, a counterweight to won strength In July, South Korean retail investors bought 4.6 billion dollars of US stocks, the most in six months, as the domestic market slumped.

  It is the main real counterweight that could slow or reverse the won's rise.
