In an era of intense business competition and rapid change, a strong organizational culture serves as a critical foundation for GC. The Company drives its corporate culture and GC SPIRIT 4 Core Behaviors as a shared mindset and way of working that unites everyone toward common goals and builds confidence both inside and outside the organization, starting from leadership-driven advocacy, continuous communication, and role modelling, so that employees at all levels understand and can apply these values in their work and daily lives, jointly propelling the organization toward its vision “To be a Leading Global Chemical Company for Better Living.”

In 2025, GC continued to reinforce its corporate culture among employees through the “GC StandOut 3DOs (Do Less, Do Now, Do More)” campaign, encouraging individuals to differentiate themselves by leveraging their own strengths, with management placing strong emphasis on embedding this culture through ongoing communication in various forums and through GMC in Action stories that convey the Company’s vision, mission, and strategic direction, while inspiring and role modelling for employees. The Company established a strong GC SPIRIT Committee and appointed Change Agents from each business line as employee representatives to drive the culture in a tangible manner, providing guidance for Change Agents to develop action plans to promote GC SPIRIT 4 Core Behaviors at department and business-line levels, and organizing quarterly Change Agent Chit-Chat sessions to facilitate exchange of perspectives and strengthen relationships among Change Agents.

The Company has designed its people management mechanisms to align with corporate values at every stage of the Employee Lifecycle, from recruitment and selection, onboarding, and 360-degree behavior evaluation involving supervisors, direct reports, peers, and relevant external stakeholders, ensuring that assessments reflect behavioral alignment with GC SPIRIT 4 Core Behaviors and recognize conduct that exemplifies the Company’s values.

Amid business challenges and the rollout of the GC StandOut campaign, employees demonstrated strong commitment by submitting new ideas via multiple channels and the GC StandOut Platform, and by actively participating in innovation initiatives and cross-functional collaboration to solve problems and create value-added projects for customers and the organization, such as process improvement projects to reduce costs, product enhancement or new product development initiatives aligned with market needs, and digital projects that increase operational efficiency. The Company also organized “GC StandOut X SEEK day: Together We Achieve More,” a major corporate event integrating GC SPIRIT 4 Core Behaviors, innovation, GRC (Governance, Risk, Compliance), safety, energy, environment, and knowledge management, providing a platform for employees to be recognized by management and colleagues, to showcase successful outcomes, and to be inspired to apply GC SPIRIT 4 Core Behaviors and the Culture Theme “GC StandOut #แตกต่างอย่างยั่งยืน” in driving initiatives that strengthen the Company’s long-term sustainability.

Accordingly, GC has set comprehensive performance appraisal criteria cover the following dimensions:

This also includes the determination of indicators that can create work commitment. GC annually conducts this type of the performance appraisals.

The assessment of the GC SPIRIT 4 Core Behaviors focuses on the ability to work as a team and creativity in line with the corporate culture.

Team-based Performance Appraisal

The system has been improved to allow Project Leader/Project Manager to directly evaluate the scores to promote an agile work format.

Agile Conversations

In addition to regular appraisals, GC also requires employees to discuss or “check-in” to share feedback in terms of work contents, goals and GC SPIRIT 4 Core Behaviors to track the progress and success of the task according to established goals as well as to provide the opportunity to discuss ways of self-development. The “check-in” is encouraged to be conducted on an ongoing/quarterly basis.

In cases of workforce reduction or termination, the Company provides written advance notice to affected employees in accordance with the Labour Protection Act B.E. 2541, with a minimum notice period of one full wage payment cycle before the effective termination date, or, where advance notice cannot be provided, wages in lieu of notice as prescribed by law. This approach ensures that employees have sufficient time to prepare and seek new employment opportunities and reflects the Company’s commitment to responsible and transparent employment practices.
