Union Bank stock falls 2.14 percent as profit rises

Union Bank stock traded at TWD 20.55 on September 29, 2026, while second-quarter net income reached TWD 2,110.32 million. Six-month profit rose to TWD 3,618.16 million.

Union Bank stock traded at TWD 20.55 on the Taiwan Stock Exchange on September 29, 2026, down 2.14 percent from the prior close of TWD 21.00. The move came as the market weighed stronger first-half earnings against a share price still below its 52-week high of TWD 24.90.

Second-quarter profit accelerates

MarketScreener reported on August 31, 2026, that Union Bank of Taiwan posted second-quarter net income of TWD 2,110.32 million, up from TWD 1,449.68 million a year earlier. That represents a 45.57 percent increase and gives the earnings story a clear numerical edge over the stock's daily decline.

Second-quarter net interest income also rose to TWD 2,681.82 million from TWD 2,322.91 million, a 15.46 percent increase. Diluted earnings per share reached TWD 0.34, compared with TWD 0.20 in the same quarter of the prior year, according to MarketScreener.

First-half numbers set the benchmark

For the six months ended June 30, 2026, net interest income reached TWD 5,249.18 million versus TWD 4,545.52 million a year earlier. Six-month net income climbed to TWD 3,618.16 million from TWD 2,656.03 million, an increase of 36.23 percent, while diluted earnings per share rose to TWD 0.67 from TWD 0.46.

The comparison matters because the latest half-year figures show growth across both interest income and bottom-line profit. For investors, the key tension is visible in the same session: earnings improved materially, yet the share price fell 2.14 percent and volume reached 4,374,365 shares.

Stock remains below yearly high

Union Bank of Taiwan's reference price stood 17.47 percent below the 52-week high of TWD 24.90 and TWD 3.76 above the 52-week low of TWD 16.79 on September 29, 2026. Its market capitalization was TWD 94.6 billion, leaving the stock's valuation story tied to whether the reported earnings growth can outweigh short-term price pressure.
