Amid the severe challenges of global climate change and the rapid evolution of the technology industry, Ennostar remains committed to its vision: “Advancing optoelectronic innovation with light; illuminating the world's future through smart sustainability.” In 2025, we not only continued to innovate in optoelectronic technology, but also embedded sustainability as a driver of the Group's growth, allowing every ray of light to become a source of energy for shared social prosperity and environmental sustainability.

Strengthening Governance and Fulfilling Our Sustainability Commitments

Governance is the cornerstone of sustainable development. In 2025, Ennostar remained among the top 5% in the Corporate Governance Evaluation and received the Platinum Award in the Sustainability Report category of the TCSA Taiwan Corporate Sustainability Award. We firmly believe that ethical management and long-term value creation are inseparable. By closely linking senior executive compensation to ESG performance indicators, we embed our commitment to carbon reduction and energy conservation into every level of organizational decision-making. At the same time, we actively invest in green technology R&D. The Group has accumulated 6,024 granted patents, and green patent proposals accounted for 80%, demonstrating our firm commitment to solving environmental issues through technological innovation.

Protecting the Environment and Accelerating Carbon Reduction

In climate action, Ennostar has moved beyond carbon reduction alone toward building resilience. We are honored to have received CDP's highest “A” leadership rating for Climate Change for two consecutive years. In 2025, our near-term emissions reduction targets were validated by the Science Based Targets initiative (SBTi). We committed to reducing Scope 1 and Scope 2 emissions by 50.4% by 2032. By 2025, cumulative emissions reductions were nearly 50% compared with the 2022 base year, primarily because the Group's China sites had achieved 100% renewable electricity use. In addition, the process-water recycling rate at Ennostar's factories in Taiwan exceeded 80%, addressing resource pressures through tangible action and setting a benchmark for the circular economy.

Advancing Shared Prosperity and Empowering Future Talent

A company's value comes not only from its operating results, but also from how it gives back to the communities where it operates. In 2025, Ennostar invested NT$7.75 million in education and training, reaching a cumulative 60,913 participants, and o icially launched a unified learning platform. The one-stop portal integrates learning resources and provides employees with a more flexible and diverse environment for self-directed learning. In social engagement, we continued to deepen our “STAR Strategy,” extending our e orts to optoelectronics science education and local public-interest initiatives. Since 2022, charitable procurement has accumulated to NT$2.74 million. This is more than one-way giving; it creates economic connections through which we and local communities co-create mutual benefit. Ennostar believes that true strength lies not in the growth of a single enterprise, but in enabling partners to advance together; and true innovation is not limited to technological breakthroughs, but also turns optoelectronics knowledge into a force that empowers the next generation.

Looking Ahead: Moving Forward with Light - More Than a Commitment, It Is Action

The journey toward sustainability has no finish line, only milestones of continuous evolution. We thank every partner who has traveled with us and helped us leave a solid footprint in 2025. Looking ahead, we will continue to place “light” at the core, leading the industry toward an inclusive ecosystem that is smarter, lower-carbon, and more people-centered. We aspire not only to lead the optoelectronics field, but also to become a pivotal force in safeguarding the future.
