STC recorded a gain on sale of equity-method affiliate shares of 13,671 million yen as a special gain due to partial disposal of FST shares, and a special loss of 3,778 million yen was recorded related to the cessation of wafer production at the Miyazaki plant. Changes in the scope of consolidation mean the impact of FST on results requires attention. The full-year forecast has been revised to net sales of 439,500 million yen and net loss attributable to owners of the parent of -3,400 million yen.\n\n### Outlook and Key Impacts\nDemand for 300mm wafers is expected to remain at high levels, and the company will continue to upgrade production equipment and improve efficiency for wafers 200mm and smaller. Note that due to the change to equity method accounting for FST, FST's net sales and profits will not be included in consolidated results from 4Q onward. See notes for foreign exchange assumptions. In the short term, consolidated profit and loss may become more concentrated, but in the long term, stable demand for advanced products and cost reduction initiatives are key to recovery.","jir_financial_highlights":"Net Sales: 332,524 (9.2% increase YoY)\nOperating Income: -4,397\nOrdinary Income: -9,886\nQuarterly Net Income Attributable to Owners of Parent: -7,422\nTotal Equity: 565,506","jir_category":"","jir_hashtags":"#SUMCO, #Earnings, #SemiconductorWafers, #FinancialInformation","jir_key_figures":"Net Sales: 332,524 million yen (9.2% increase YoY)\nOperating Loss: -4,397 million yen\nOrdinary Loss: -9,886 million yen\nQuarterly Net Loss Attributable to Owners of Parent: -7,422 million yen\nFull-Year Net Sales Forecast: 439,500 million yen\nFull-Year Net Income Forecast: -9.72 yen\/share (per share)","jir_meta_title":"Sumco Corporation 2026 Fiscal Year Third Quarter Results | Sales Growth but Larger Losses","jir_meta_description":"Summary of Sumco Corporation's third quarter results for the fiscal year ending December 2026.
