UMC today announced it placed in the top 5% in the 12th Corporate Governance Evaluation conducted by the Taiwan Stock Exchange (TWSE) and Taipei Exchange (TPEx). Since the evaluation was first introduced, UMC has consistently ranked in the top 5% for 12 consecutive years, placing it among a select group of companies to have maintained this distinction. The result reflects UMC’s ongoing efforts to strengthen its corporate governance framework.

The evaluation is based on four key pillars: protection of shareholders’ rights and interest, structure and operation of Board of Directors, information transparency, and sustainable development. UMC has actively taken steps to enhance diversity on its board of directors. The current board is composed of nine members with diverse professional backgrounds, with independent directors accounting for two-thirds of the board and female directors representing one-third. UMC has also established stock ownership guidelines for executives, strengthening the alignment of interests between management and shareholders.

UMC has been actively advancing sustainable development. In 2026, the company not only named to the Top 1% of the S&P Global Sustainability Yearbook, but also achieved the highest AAA rating in the MSCI ESG Ratings, demonstrating its leadership in environmental, social, and governance performance. UMC will continue to turn its sustainability commitments into concrete actions and set a benchmark for the industry.
