Waste Management

• The Group adheres to a management policy of reduction and environmental protection, striving to reduce waste generation and pollution to minimize environmental impact. In Taiwan, the parent company operates in a general office building. Most waste consists of general domestic waste, with no industrial waste. In 2024, as all waste was handled collectively by the building’s management, the total amount of general domestic waste could not be recorded.
  
• In China, the waste is currently handled through qualified third-party partners under contractual agreements to ensure waste is disposed of in compliance with regulations. In its production process, the Group’s subsidiary Amertek Computer needs to clean motherboards and fixtures and uses an environmental tower to recover organic solvents. Cardboard, plastic, pallets, brittle trays, board edges, and organic solvent waste are all properly recycled by third-party partners to reduce environmental impact. All waste from Prime Technology is also processed by licensed third-party partners, with no negative environmental impact. The quantities of waste generated are presented in the table below.

Water Resource Management

• The Group is committed to improving water use efficiency, with tap water as the main source. Through annual monitoring of water consumption and water use intensity, management strategies and conservation targets are formulated, and water-saving measures are actively promoted. In 2024, the Group commissioned third-party testing of discharge water, and the results were normal.
  
• In 2024, the total water withdrawal of Taiwan and China operations was 173,754.36 cubic meters, including 10,413.99 cubic meters in Taiwan and 163,340.37 cubic meters in China. Prime Technology saved 12.6 cubic meters of water through its wastewater filtration and reuse system.
  
• According to the World Resources Institute’s (WRI) Water Risk Atlas tool, the Group’s water withdrawal areas are classified as medium-to-low water stress, with no high-water-stress areas. These results demonstrate the Group’s commitment to water resource management and the ongoing improvement of water use efficiency.
  
• The total water withdrawal of Taiwan and China operations are presented in the table below.

	2023	2024
Taiwan water withdrawal (cubic meters)	9,849.00	10,413.99
China water withdrawal (cubic meters)	258,197.70	163,340.37
Total (cubic meters)	268,046.70	173,754.36

Note 1: Based on water bill conversion, 1 water unit = 1 cubic meter = 0.001 thousand cubic meters = 0.001 million liters.

Note 2: Annual total water withdrawal in Taiwan only includes FIC and Ubiqconn. Prime Base Inc.’s total water withdrawal in 2024 was 4,359.40 cubic meters. As no 2023 water withdrawal data is available for Prime Base Inc., it is not included in the comparison.
