Message From WHA Group CEO

In 2025, the global business landscape continues to face multifaceted challenges arising from geopolitical tensions, market volatility, rapid technological advancement, and increasing environmental challenges. Organizations are expected to leverage digital innovation to enhance efficiency, strengthen operational resilience, address climate impacts, and protect natural ecosystems in ways that contribute to nature-positive outcomes. In addition, nature-related issues are increasingly being integrated into core business strategies to support long-term sustainable growth.

Amid these challenges, WHA Group remains committed to driving sustainable growth as a tech-driven organization by integrating innovation and ESG principles into all dimensions of its operations. The Group has also announced its 5-year sustainability vision and strategic direction under the mission “WHA: WE SHAPE THE FUTURE,” including the establishment of clear targets and timelines. Furthermore, the Group aims to allocate investment toward sustainable businesses, including renewable energy, wastewater reclamation, and Mobilix, in order to integrate sustainability with business growth and create sustainable value in all dimensions.

The Group believes that long-term success must go hand in hand with community development and building relationships with stakeholders across all sectors. The Company implements five key social initiatives covering education development, health and quality of life, environment, careers and economic opportunities for communities, as well as activities related to traditions, religion, and culture. The Group emphasizes continuous engagement and communication to create measurable outcomes, strengthen trust, foster shared growth, and enhance Thailand’s social and economic resilience.

In 2025, the Group received recognition for sustainability performance through awards at both national and international levels, including the AAA rating in SET ESG Ratings and the SET Awards of Honor. In addition, the Group was selected as a member of the S&P Global Sustainability Yearbook for the fourth consecutive year and ranked among the Top 1% globally in the S&P CSA sustainability assessment for the Real Estate Management & Development industry for the second consecutive year.

As the Chairman of the Executive Committee and Group Chief Executive Officer, and on behalf of the Board of Directors and management, I would like to express my sincere appreciation to all stakeholders for their continued trust and support. These achievements are made possible through the dedication of our people and the collaboration of all sectors, enabling the Group to create sustainable value while contributing to Thailand’s future economic and social development. The Group remains committed to strengthening its core businesses and leveraging innovation and technology to develop green business models that create positive impacts on society and the environment under balanced good corporate governance. WHA Group firmly believes that it will continue to help shape a sustainable future for Thailand and the global community.
