Sumco corrects FY2025 third quarter presentation error

Sumco Corporation announced on November 14, 2025, a correction to its "Results for Third Quarter of FY2025 (Ended September 30, 2025)" presentation, originally filed on November 11, 2025. The error was identified in the bar chart titled "Depreciation and Capital Expenditure" on page 26 of the presentation materials.

The correction specifically addresses the vertical axis scale of the "Depreciation and Capital Expenditure" bar chart. The "before correction" chart showed a vertical axis scale up to 3,000 (billions of yen), while the "after correction" chart displays a revised scale up to 300 (billions of yen), indicating a tenfold overstatement in the original visual representation of these figures.

Despite the visual correction, the accompanying textual information remains consistent, stating that capital expenditure peaked in FY2023 and depreciation expenses are expected to peak in FY2026. The corrected presentation materials are available on the company’s website.
