SEC filingUnited Microelectronics Corporation announced on 2026-05-15 that its cumulative share repurchases reached 3,780,000 common shares valued at NTD$406,598,693, exceeding the NTD$300 million disclosure threshold and representing 0.16% of issued shares.
This 6-K filing discloses a routine milestone in UMC’s ongoing share repurchase program: crossing the NTD$300 million cumulative value threshold on 2026-05-15. The repurchase of 3,780,000 common shares at an average price of NTD$107.57 reflects disciplined execution against the program’s objectives, with the company now holding 20,531,000 treasury shares (0.16% of issued shares). While the filing confirms progress, it does not disclose the original authorization size, remaining capacity, timeline for completion, or strategic rationale — all of which would be material for assessing capital allocation priorities. For investors, this represents a modest but concrete return of capital, consistent with UMC’s historical practice, though the scale remains small relative to market capitalization and does not signal a material shift in financial policy or earnings distribution strategy.
