SUMCO to reduce stake in Taiwanese subsidiary and shift to equity-method accounting
Monday, March 2, 2026 at 03:43 AM
Japanese silicon wafer manufacturer SUMCO has announced it will sell a portion of its shares in its Taiwanese subsidiary, Formosa SUMCO Technology. Following the sale, the subsidiary will transition to an equity-method affiliate. This move represents a shift in the capital structure and management of its manufacturing footprint in Taiwan.
Context
Japanese silicon wafer leader SUMCO will reduce its stake in its Taiwanese subsidiary, Formosa SUMCO Technology (FST), transitioning the unit to an equity-method affiliate. The company is selling approximately 13.4 million shares, a 1.7% stake, lowering its total voting rights from 45.6% to 43.9%. This restructuring is scheduled for completion by late March 2026 and changes how the group manages its critical Taiwanese manufacturing operations.
The move aims to enhance capital efficiency by deconsolidating FST's financials from SUMCO's balance sheet. While the subsidiary will no longer contribute to consolidated revenue, SUMCO will still record its share of the unit's net income. This shift provides the firm with greater financial flexibility to reallocate capital toward next-generation 300mm wafer production. The divestment helps SUMCO optimize its asset portfolio while maintaining a strategic presence in the Taiwanese semiconductor ecosystem.
