SUMCO to Cut Stake in Taiwan Unit, Reclassify It as Equity-Method Affiliate

SUMCO Corporation ( (JP:3436) ) has provided an update.

SUMCO Corporation will reclassify its Taiwanese unit Formosa SUMCO Technology Corporation from a consolidated subsidiary to an equity-method affiliate by selling a 5.2% stake via the Taiwan securities market. The move will reduce the group’s voting rights from 43.2% to 38.0%, while maintaining a strong cooperative relationship and FST’s role as a major production and sales base for 300 mm and 200 mm wafers in Taiwan.

The change reflects SUMCO’s review of its capital relationship with joint venture partner Formosa Plastics Group and aligns FST’s status with its listed-company profile. The timing of completion and the resulting impact on SUMCO’s consolidated earnings for the year ending December 31, 2026 remain undetermined, leaving investors watching for subsequent disclosures on financial effects and governance implications.

The most recent analyst rating on (JP:3436) stock is a Hold with a Yen1517.00 price target. To see the full list of analyst forecasts on SUMCO Corporation stock, see the JP:3436 Stock Forecast page.
