The filing focuses exclusively on share repurchase activity and does not provide standard financial metrics such as revenue, profit, cash flow, margins, debt, or liquidity.
- Repurchase Program Ceiling: NTD 16,214,828,000
- Shares Repurchased in Period: 12,717,000 shares

Material Changes
The primary material event is the conclusion of the share repurchase period originally scheduled from September 3, 2025, to November 1, 2025. The company executed the repurchase through October 31, 2025, but did not fully utilize the authorized monetary ceiling or reach the target share count of 15,000,000 shares for this specific tranche.
Management Commentary and Risks
Reason for Non-Completion: Management stated that the repurchase was not fully executed due to a phased strategy designed to protect shareholder interests and account for market mechanisms. The company adjusted its buying activity based on stock price fluctuations within the authorized range of NTD 16.80 to NTD 32.00.
Procedural Note: The announcement was issued after market close on the last trading day because the final scheduled date of the repurchase period (November 1, 2025) fell on a holiday.
Investor Verification Checklist
