Materiality Assessment

Step 1
Identify the stakeholders
Undertake stakeholder identification based on past experiences and industry characteristics to identify stakeholders.
Step 2
Collect sustainability topics
Based on the company’s industry characteristics and internal topics of concern, and with reference to the GRI Standards, domestic and international sustainability trends, industry benchmarks, and peer information, common industry topics were identified through an intersection analysis to determine the company’s key sustainability issues.
Step 3
Assessing the significance of impacts
Through workshops and questionnaires, the Sustainable Development Team and senior management rated sustainability issues. The assessment covered the positive/negative impacts of the issues on the economy, environment, and people (including human rights). For each issue, both the “likelihood of positive/negative occurrence” and the “extent of impact” were evaluated to determine the overall impact level.
Step 4
Establish material substantiality topics
Based on the ranking of impact intensity in Phase 3, the top 8 issues were selected as the Company’s Material Topics.

Forging Resilience Amid Change, with Dual Engines Driving a Sustainable Future
For most companies, 2025 remained a challenging year. The global industrial environment continued to evolve, with escalating geopolitical risks, accelerating supply chain restructuring, and increasingly stringent energy transition and green trade regulations, confronting companies with an unprecedentedly complex landscape. For Win Win Precision Technology, these changes are not only external pressures, but also an important reminder: to achieve long-term development, a company cannot focus solely on short-term revenue and orders, but must build a solid foundation and continuously strengthen its fundamentals.

Throughout our journey, we have always believed that prudent management is not about being conservative, but about continuing to make sound and long-term choices amid change. We continue to deepen our semiconductor and new energy businesses as two engines of growth. On the one hand, we meet the semiconductor industry's strong demand for precision manufacturing and stable supply; on the other hand, we actively participate in the global energy transition through solar modules and green energy solutions. The two business groups may appear to be developing independently, but in fact share the same core values: quality, trust, and long-term commitment.

2025 was also an important milestone in deepening our sustainable governance. With the formal establishment of the Sustainability Office, the Company promotes various sustainability initiatives in a more systematic manner. For us, ESG is not merely about the results of reports or evaluations, but a management capability that can be developed over the long term and continuously improved. We have gradually integrated efforts that were previously dispersed across various departments, covering GHG inventory, energy management, information security, supply chain management, talent development, and employee well-being. These efforts cannot be accomplished overnight, but as long as we stay on the right path and continue to build on our progress, they will ultimately be transformed into genuine corporate competitiveness.

In terms of product and market strategies, we continue to uphold high quality and high reliability. Facing intensifying competition in the global PV market, the Company continues to deepen its presence in premium markets such as Europe and Australia, while building long-term customer trust through its own brand WINAICO. The next-generation Back Contact high-efficiency modules launched in 2025 not only improved product efficiency, but also reflected our emphasis on long-term stability, resilience to extreme weather, and customer value. The faster the market changes, the more customers need reliable products and partners. This is precisely why we continue to invest in technology and quality.

Looking back on the past year, the Company's efforts have gradually begun to yield results. We participated in the 12th (2025) Corporate Governance Evaluation for the first time and achieved a ranking in the 21% to 35% range. This is not only a recognition, but also a new starting point. At the same time, the Company continued to maintain SA8000 and ISO 50001 certifications, strengthening its commitment to human rights, labor conditions, and energy management; it also received recognition at the Taiwan Corporate Sustainability Awards (TCSA) and the Excellence in Corporate Social Responsibility, demonstrating strong external recognition of our sustainability practices. More importantly, we continue to translate sustainability into tangible value for customers. In response to international regulations and carbon information disclosure requirements, the Company has obtained Environmental Product Declaration (EPD) certification to help customers more accurately understand product environmental information and strengthen our role as a responsible and trusted supply chain partner. Sustainability is not an abstract concept, but is concretely implemented in products, processes, quality, delivery, and customer relationships.

Talent has always been the most important foundation of the Company. In a rapidly changing environment, corporate competitiveness comes not only from equipment and systems, but also from a team of partners who are willing to learn, take responsibility, and solve problems. Therefore, we continue to optimize mechanisms for attracting, developing, and retaining talent, strengthen education and training and cross-departmental collaboration, enable employees to grow through practical experience, and allow the organization to continuously enhance its resilience amid challenges.

Looking ahead, sustainability is not only a corporate responsibility, but also a key factor in whether we can continue to earn customer trust and market recognition. We will continue to deepen the integration of ESG and business strategies, steadily advancing key initiatives step by step across corporate governance, product innovation, environmental management, the supply chain, and talent development. Facing an uncertain external environment, we do not pursue short-term visibility, but are committed to building corporate value that can stand the test of time.
Win Win Precision Technology will continue to uphold the core spirit of "ethical governance, innovation and continuous improvement, and shared well-being and prosperity," advancing steadily amid change, forging resilience through challenges, and moving toward a more enduring future with sustainability as a driving force. We will also work together with employees, customers, suppliers, and all stakeholders to build trust through sound governance, create value through responsible actions, and jointly build a sustainable enterprise characterized by resilience, trust, and long-term value.

Chairman and CEO,
Win Win Precision Technology Co., Ltd.
