YEAR 2024 IN REVIEW

2024 IS A YEAR OF RESILIENCE, TRANSFORMATION AND SUSTAINABILITY FOR TESSENDERLO GROUP

2024 is the year of resilience, transformation and sustainability for Tessenderlo Group. Thanks to the unwavering commitment and impact of our colleagues and the leadership of our Board of Directors and the Executive Committee, we have weathered a year of unprecedented challenges while laying the foundation that will enable further long-term growth.

Chairman of the Board of Directors - Wouter De Geest

We do business in a VUCA (volatile, uncertain, complex, ambiguous) world characterized by extraordinary global challenges.

The effects of the war in Ukraine continued to disrupt supply chains, drive up energy volatility and commodity costs. At the same time, geopolitical tensions in the Middle East and changing dynamics between the U.S. and China added further layers of complexity to the global landscape.

Climate change provided its own pressing challenges. For Europe, the energy situation remained precarious, as fluctuations in oil and gas prices impacted industrial activities. Tessenderlo Group has consistently demonstrated its adaptability and continued on his path for profitable growth.

Our commitment to sustainability remains steadfast. With the introduction of the Corporate Sustainability Reporting Directive (CSRD) regulations, we have proactively adapted to these new standards, ensuring that Environmental, Social, and Governance (ESG) principles are deeply embedded in our long-term strategy. At the same time, we recognize the importance of balancing sustainability efforts with maintaining our competitiveness and profitability. As we move forward, we also welcome efforts to reduce

the administrative burden associated with reporting requirements, enabling us to focus on driving meaningful impact while remaining agile in a competitive market.

As a collective and diverse board, together with the Executive Committee of Tessenderlo Group, we regularly meet in person at our headquarters or close to our production facilities to proactively address these challenging circumstances. Our collective resilience, agility and vision together with the passion of our global team will enable us to continue thriving in a world full of complexities.

CEO Tessenderlo Group - Luc Tack

2024 has tested our resilience and adaptability like never before. High market volatility and operational challenges defined the past year, but Tessenderlo Group emerged stronger and managed to balance immediate action with long-term strategic positioning.

Despite these obstacles, our operating performance remained robust. This success is due to our focus on operational excellence, our ability to respond quickly to our customers' needs and our strategic efforts, including

acquisitions and the launch of major growth initiatives. In January 2024, we also welcomed a new Executive Committee (ExCom) team, which brought fresh perspectives and energy to lead us into the future.

We looked ahead and laid the foundation for financial sustainable performance. This includes further developing our strategy, investing in automation and innovation, and strengthening relationships with our customers by striving for commercial excellence. Tessenderlo Group's adapt- ability, combined with a forward-looking vision, ensures that we are well positioned to meet both current challenges and future opportunities.

CTO Tessenderlo Group - Sandra Hoeylaerts

The shift toward a financially sustainable future focuses on automating processes and driving product and process innovation while also prioritizing the development of future-proof skills and competencies. At the same time, it emphasizes the well-being and safety of our colleagues.

In 2024, we invested fully in our people. Targeted training and development programs ensure that our employees have the tools and knowledge they need to excel in this rapidly changing world. Safety and well-being were key areas of focus, supported by initiatives to always put safety first and encourage a healthy and engaged workforce. The results of our recent engagement survey confirm our commitment to listen to and act on the voices of our employees. It underscores the importance of open dialogue with our workforce so that our transformation is guided by their voices.

Through our transformation efforts, Tessenderlo Group is building a future that is not only economically robust, but also socially and environmentally responsible.

CFO Tessenderlo Group - Miguel de Potter

Resilience and adaptability are only possible with a strong financial base. In 2024, we effectively managed key financial parameters to secure our ability to thrive in times of uncertainty.

Strategic capital allocation remained a priority. We balanced strategic investments in innovation and sustainability with shareholder returns through share repurchases and dividends. Strong cashflow management allowed us to remain agile and fund long-term growth initiatives.

Our commitment to good governance and ethics was strengthened by the implementation of enhanced compliance measures, including a whistle- blowing policy and an updated Code of Conduct. These initiatives reflect our commitment to transparency, integrity and building trust with our stakeholders and employees.

OPENING OF A STATE-OF-THE-ART FERTILIZER PLANT AND RECOGNITION FOR SUSTAINABLE AGRICULTURE

On Thursday November 21, 2024, Tessenderlo Kerley International proudly opened its new liquid fertilizer plant at the Chemelot site in Geleen (NL). The new plant, which produces ammonium thiosulphate (Thio-Sul®), a liquid fertilizer that supplies nitrogen and sulfur, plays a crucial role in the sustainable agriculture sector. The decision to build the new Thio-Sul® plant at Chemelot was a natural choice. Here, Tessenderlo Kerley is not only close to key customers in the Benelux, Germany and northern France, but also to the critical raw materials essential for the production process. The new, state- of-the-art production facility in Geleen strengthens our position as market leader and embodies our long-term commitment to sustainability, innovation and growth.

The homologation of Thio-Sul® by the French government as a nitrification inhibitor was also achieved in 2024, marking a significant step in sustainable farming. Official recognition highlights Thio-Sul®'s ability to reduce nitrate leaching and ammonia volatilization, enabling farmers to optimize nitrogen use, improve yields, and lower their carbon footprint. The research was done by our own research team in collaboration with the Auburn university. This milestone aligns with Tessenderlo Group's commitment

to sustainability and supporting the agriculture sector in achieving greener practices.

STRATEGIC ACQUISITION OF TIGER-SUL PRODUCTS

Tessenderlo Kerley, Inc. (Agriculture Segment), has acquired Tiger-Sul Products, LLC, a North-American provider of sulfur-based fertilizer products. The acquisition closed on November 6th, 2024. The acquisition enhances Tessenderlo Kerley's specialty fertilizer portfolio, aiming to deliver improved crop yields, greater control for farmers, and healthier soils for all. With this acquisition we also have our first production plant in Canada expanding our regional footprint in North-America.
