DELIVERING RESPONSIBLE

GROWTH AND TRANSPARENCY

2025 was a transformative year for Holcim. We launched our NextGen Growth 2030 strategy, and are implementing our vision to be the leading partner for sustainable construction.

Our NextGen Growth 2030 strategy aims to unlock significant growth and value creation for people, customers and shareholders, and indeed is already doing so as Holcim generated strong profitable growth for the full-year 2025.

Our strategy anticipates and addresses the powerful megatrends shaping the future of construction, such as population growth and urbanization, as we create value for people, customers and society.

This report demonstrates how Holcim's tax contributions are linked to this process. As a responsible global taxpayer, we contribute to the socio-economic development of communities across the world. We view our tax contributions as essential investments: tax transparency is not just a legal requirement, but is a core pillar of our corporate responsibility.

In 2025, we upheld our philosophy of paying taxes where economic value is created. This is the sixth consecutive year that we have issued this report, consistently meeting the highest

standards of transparency. We view our tax contributions as part of our value creation strategy, ensuring we reinforce our role as a reliable partner to our stakeholders and a leader in sustainable construction.
