Furthermore, Realtek received the Bosch Global Supplier Award in the “Materials and Components” category, making it one of the few suppliers worldwide to be honestly listed as one of Bosch′s top global suppliers for leading technologies and services.

For the past thirty-nine years, Realtek has been committed to sound and ethical management. Through meticulous corporate management and strategic planning, we implement corporate governance by integrating various professional units within the organization. This ensures that all aspects of our operations align with our responsibilities for sustainable development. Our practices include implementing legal compliance, information security management, and risk management, enhancing the transparency of information disclosure, safeguarding shareholder rights, strengthening the functions of the Board, respecting and protecting human rights, and maintaining active communication with our stakeholders on various ESG issues. Corporate governance and ethical integrity are the cornerstones of our pursuit of corporate sustainability and represent our core responsibilities.We will continue our diligent efforts to report on our progress and achievements.

Fulfilling the Green Commitment
While pursuing revenue and profit growth, Realtek also actively supports international netzero emission initiatives. Realtek has signed the commitment letter for the Science Based Targets initiative (SBTi) and, in alignment with its guidelines, established science-based reduction targets. These targets are scheduled for submission to the SBTi for review in 2026. Through rigorous target setting and execution, the company aims to achieve net-zero emissions by 2050. Regarding the use of renewable energy, we are actively planning and implementing green power generation projects. We have installed solar power systems at Hsinchu Office 1, Office 2, and Office 3 to reduce the environmental impact of our operations. Furthermore, we have set a goal to achieve RE50 by 2030 and have voluntarily committed to achieving 100% renewable energy across the entire Group and net-zero emissions by 2050.

For green products, Realtek incorporates energysaving and environmental principles into the design process. This approach drives innovation and supports steady growth and profitability, while simultaneously reducing product power consumption and increasing durability. By minimizing energy and resource consumption throughout the product lifecycle, we make a tangible contribution to global energy conservation and carbon reduction initiatives. To foster a culture of environmental sustainability and realize our goals, we actively promote environmental advocacy and provide training, leveraging systematic management to ensure company-wide consensus on environmental responsibility.

Talent Strategy and Corporate Culture
Realtek is in a knowledge and technology intensive semiconductor IC design industry, where talent and intellectual property are the most important resources. These are the driving force behind the company′s advancement and cornerstones for deepening our sustainable competitiveness. Over the years, Realtek has continuously pursued talent development strategies to enhance innovation and optimize the organizational competitiveness to respond to short-, medium-, and long-term operational and strategic development needs. Realtek′s talent development strategy is built on the core philosophy of “selfconfidence and trust in people,” creating an open learning and mutually trusting work environment. Internally, we have established a dual-track development system for both technical integration and management, providing high-potential employees with crossdepartmental rotation opportunities and facilitating the development of a robust pipeline of senior leaders. In terms of talent cultivation and development, we use the six major field academies of Realtek Corporate University to develop sustainable education and training plans, covering organizational development learning and employee self-breakthrough education and training structures, cultivating all employees' knowledge, skills, attitudes, and the core qualities of sustainable innovation and organizational culture. In terms of improving work life, Realtek integrates various employee welfare matters to afford a friendly workplace environment, promote high-quality organizational environment renovation, create team collaboration and vitality. To encourage employees to actively contribute to the company′s success, Realtek launched the Employee Stock Purchase Plan in the first half of 2025. This initiative is designed to motivate employees, strengthen organizational engagement, and enable them to grow alongside the company while sharing in its business success. In addition, Realtek provides employees health care services and environmental testing projects, and conduct an annual employee engagement survey to progressively drive various improvement initiatives to create a safe and reliable working environment.

Realtek′s corporate culture is defined by self-confidence and trust in people, teamwork, innovation, and vitality. Self-confidence is derived from professionalism; trust in people is manifested through sharing, belief in the team, and helping others. Teamwork stems from coordinating with and supporting the team spontaneously of their own volition. Innovation involves actively pursuing leading-edge breakthroughs and actively creating new values, new fields, and new opportunities. Vitality is about proactivity and passion. We believe this organizational culture provides Realtek employees with a shared vision and direction, enabling the organization to focus and align its efforts, and build a unique and sustainable competitive advantage.

Social Care and Sustainability Outlook – Co-prosperity with the Global Community
Fulfilling corporate social responsibility is one of Realtek′s established operational goals. We continuously invest in planned social care projects that address diversity, inclusion, and specific needs, and integrate resources such as funds, manpower and supplies to practice corporate social citizenship participation. Realtek continues to advance the “Realtek Charity and Sustainability Three-Year Plan,” a new shared-value sustainability initiative, and, through the concerted efforts of all Realtek employees and stakeholders, actively promotes social participation to create shared prosperity for society. In 2025, Realtek invested more than NT$13 million to support charitable and public welfare activities. In terms of public welfare project planning, Realtek reaffirmed the commitment to rural education development and children′s reading projects, fostering the pursuit of knowledge and creating learning opportunities. In addition, Realtek actively supports domestic performing arts groups, as well as the cultivation of artistic and cultural talents, promoting the development of local arts and culture. Realtek also continues to collaborate with its partner, the Old Tree Environmental Protection Foundation, sponsoring the “Happy Storyteller – Love Trees Campus Co-Learning Program." Centered on ecological education and stories of old trees, the program held more than 30 tree-conservation and nature-knowledge education sessions in 2025, engaging over 1,500 student attendances in total. Together, these efforts stimulate and create positive influence in corporate citizenship and hold far-reaching significance.

Last but not least, Realtek understands the expectations and needs of various stakeholders and employs them to plan a blueprint for sustainable development. We will adhere to the positive, rigorous and prudent approach, continue to promote sustainable development, and achieve sustainable operation through practical actions. We would like to express our gratitude to our partners for their continuous interest to Realtek, and to work with us to support global sustainable development initiatives.

Realtek remains committed to contributing wholeheartedly to both corporate and global sustainable development, embedding sustainability thinking into the mindset of every member of the organization. By integrating the organization-wide participation with operational policies and objectives, we work together to achieve and advance Realtek′s sustainability goals and commitments!
