Kaohsiung, Taiwan, November 15, 2021. ASE Technology Holding Co., Ltd. (TAIEX: 3711, NYSE: ASX), the leading provider of semiconductor packaging, test and system assembly services, today announced that it has achieved the best overall performance on the Dow Jones Sustainability Indices (DJSI) – Semiconductors and Semiconductor Equipment Industry Group for the sixth consecutive year. The DJSI achievement is a firm recognition of ASE’s outstanding performance in sustainability in tandem with growth and innovation in a competitive global industry.

As the best-in-class company on the Semiconductors and Semiconductor Equipment Industry Group, ASE received the highest scores in 13* categories including customer relationship management, innovation management, risk and crisis management, privacy protection, environmental reporting, product stewardship, social reporting, human rights, and corporate citizenship and philanthropy. This year, a total of 65 companies were assessed in the Semiconductors and Semiconductor Equipment Industry Group and 9 of the companies including ASE made the cut on the 2021 DJSI World. The DJSI World index represents the top 10% of the largest 2,500 companies in the S&P Global Broad Market Index based on long-term economic, environmental and social criteria.

“Despite facing headwinds and the uncertainty of a prolonged Covid-19 pandemic since 2020, ASE managed to record healthy profits and a steady revenue growth of 21% in the first three quarters of the year,” said Jason Chang, Chairman and CEO, ASE Technology Holding. “It is an honor to be selected as a DJSI industry leader again on the 2021 index, and we will continue to play an active role contributing positively to the environment, economy and society,” he continued.

Charting a Low Carbon Future. As the threat of a climate crisis intensifies, ASE is aggressively reducing carbon emissions through the submission of targets to SBTi (Science Based Targets Initiative), committing to Net Zero emissions by 2050. Around the world, ASE has 11 factories powered completely by renewable energy. Overall, the company has increased its renewable energy use by 38% year on year, accounting for 18% of total energy consumption. ASE operates the largest semiconductor water recycling facility in Taiwan. The water recycling facility allows ASE to reuse each drop of water up to three times and surpass an accumulated volume of 20 million tons of water recycled.  

Creating a Quality Workplace. To mitigate the impact of Covid-19 on business operations, ASE continues to invest in technology and infrastructure to develop robust response and recovery mechanisms. The well-being of employees are top priorities at ASE and the company is committed to providing a quality environment that ensures their health and safety. In the early days of the pandemic, the company built a class 100K clean room facility to manufacture high quality medical-grade face masks for distribution to employees free of charge.

Promoting Social Cohesion. The ASE Cultural and Educational Foundation and the ASE Foundation for Environmental Sustainability are responsible for developing long-term social projects in line with ASE’s social involvement strategy through ‘environmental conservation’, ‘industry-academia collaboration’, ‘community engagement’ and ‘public advocacy’. Programs include installation of LED lights in schools, smart grid deployment in Shanlin Junior High, reforestation projects and elderly care activities. The acceleration in digital transformation has allowed ASE to extend the deployment of digital technologies into the public education realm. Recently, ASE has incorporated augmented reality (powered by a fast 5G mmWave network) at its Green Technology Education Center. The center uses AR to offer visitors an immersive experience that increases their understanding of ASE’s strategies in water recycling and water management.

‘At ASE, we are driving our global operations towards higher ESG standards in line with the company’s Integrate, Expand and Innovate strategies. We remain committed to leading the charge in improving the quality of life in a smart world and creating a better future for all,’ Jason Chang concluded.
