Taiwan Semiconductor Manufacturing Company Limited is slightly adjusting its previously declared cash dividend per share for the fourth quarter of 2025. The board had approved a total cash dividend of NT$155,595,147,126, equal to NT$6.0 per common share, on February 10, 2026, with payment scheduled for July 9, 2026. Because some shares from 2022, 2023 and 2024 restricted stock awards were reclaimed between the approval date and the dividend record date, the number of common shares outstanding changed slightly. As a result, the cash dividend for the fourth quarter of 2025 is now set at NT$6 per common share, which the company describes as a miniscule adjustment.
