Through sustained and systematic public welfare efforts, the Company continues to address societal needs and create substantial positive impact.

Annually, the service records over 360 uses and more than 360 service hours, while simultaneously supporting the employment of persons with disabilities and promoting employee health and well-being.

Employee Participation and Cross-Company Community Initiatives

In 2024 to 2025, Solid State System co-hosted the “Step by Step Billion Walk Challenge” with Cathay Life Insurance Group, encouraging employees to participate in health promotion and sustainability-related activities. The event incorporated competitions and incentive mechanisms to enhance participation and invited multiple companies to form a cross-company community initiative.

The event attracted approximately 273,000 participants who accumulated around 72 billion steps. NT$7 million was contributed to support two rural community development projects:
