Selection of New Suppliers
Simplo Technology adopts a rigorous review mechanism when selecting new suppliers. Suppliers with good market reputation and environmental management systems can be directly included in the list of new qualified suppliers; those who do not meet the criteria will be required to make improvements within a specified period and can only be formally included in the list after passing the reassessment.
In 2024, both of the 2 new suppliers filled out the ESG selfassessment form and were selected in accordance with the Supplier Management/Evaluation and Assessment Procedures. This demonstrates that the Company continues to apply high standards of sustainability criteria in the initial screening process for suppliers, ensuring that the supply chain is environmentally and socially responsible at the source.

According to the audit results, they were divided into three levels of red, yellow, and green, and they were managed according to different levels. In the 2024 audit results, there were no red-light disqualified manufacturers.

These issues included overtime work violations, incorrect calculation of social security contribution base, inaccurate personal protective equipment allocation and fitting, and blocked emergency exits or evacuation routes. Regarding the non-compliant issues, suppliers have been requested to provide improvement plans and their implementation is being monitored to ensure all deficiencies are effectively addressed. In response to common deficiencies among suppliers, we have planned to conduct relevant courses to provide guidance and assistance for their improvement.
