UMC Files Capital Reduction, Sets Convertible Bond Price at NT$130.7
Taiwan chipmaker completes share cancellation tied to restricted stock awards and announces conversion terms for its second domestic convertible bond offering.
Capital Reduction Finalized
United Microelectronics Corporation (UMC) completed a capital reduction following the cancellation of restricted stock awards, according to a 6-K filing submitted August 14, 2026. The Taiwan-based chipmaker, with a market capitalization of approximately $47 billion, received regulatory approval on August 10 and completed the capitalization change registration the same day (6-K filing, 2026-08-14).
The capital reduction lowered UMC's paid-in capital from NT$125.77 billion to NT$125.70 billion, canceling 6,890,971 shares. Total shares outstanding decreased from 12.546 billion to 12.540 billion shares. The adjustment marginally increased book value per share from NT$35.38 to NT$35.40, calculated based on second-quarter 2026 consolidated financial statements reviewed by certified public accountants (6-K filing, 2026-08-14).
Convertible Bond Pricing Announced
UMC disclosed the conversion terms for its second domestic unsecured convertible corporate bond on August 14. The issuance became effective upon filing with Taiwan's Financial Supervisory Commission under FSC Letter No. 11503489291 dated July 17, 2026 (6-K filing, 2026-08-14).
The company set the conversion price at NT$130.7 per share, representing a premium of 104.98% over the base price. The base price of NT$124.5 per share was determined using the average closing price of UMC common shares over the one business day prior to the conversion price determination reference date of August 14 (6-K filing, 2026-08-14). At last close, UMC traded at NT$121, below both the base and conversion prices.
The convertible bond provides investors the option to convert debt into equity at the predetermined price, a common financing mechanism that allows companies to raise capital at lower interest rates while offering potential upside to bondholders.
Insider Activity Reported
The filing also included required disclosures regarding trading and pledging of UMC common shares by directors, executive officers, and 10% shareholders for July 2026. The document referenced changes between June 30 and July 31, 2026, though specific transaction details were not itemized in the filing excerpt (6-K filing, 2026-08-14).
Looking Ahead
According to MarginX data, UMC is scheduled to report August 2026 sales and trading statement results on September 4, followed by third-quarter 2026 earnings on October 28. The Federal Open Market Committee rate decision is set for September 16, which could influence semiconductor sector valuations.
The dual announcements reflect routine corporate housekeeping for the foundry operator, which competes in the global semiconductor manufacturing market alongside larger rivals. The capital reduction streamlines UMC's equity structure following the expiration or cancellation of restricted stock compensation, while the convertible bond offering provides an additional financing tool as the company navigates capital-intensive chip production cycles.
