In corporate news, Samsung Electronics (KRX:005930) struck a last-minute deal with its labor union, and as a result of the agreement, it will distribute about 40 trillion won among its 78,000 employees in the semiconductors division.

Under the proposed terms, Samsung employees could receive average bonuses of about 513 million won, the news agency reported, based on its calculations using the projected 2026 operating profit.

The company reported average employee pay of 158 million won last year.

Under the tentative deal, which still requires labor union approval, the chipmaker will distribute 10.5% of profit as stock bonuses and an additional 1.5% in cash. The bonus program will run annually for 10 years, given that profit targets are achieved. Analysts estimate Samsung's operating profit could surge sevenfold to around 333 trillion won in 2026.

Shares of Samsung Electronics fell more than 2% at market close.
