"To move from vision

to value, we must collaborate with all our

stakeholders to bring the best solutions to life."

Peter Vanacker,

Chief Executive Officer, LYB

Sustainability, at heart, is about reimagining the future. It's about looking at the status quo and envisioning how we can do better. It's about reinventing and revitalizing old ways of working. It's about creating that vision and translating it into genuine, tangible change.

At LYB, we believe value is created by being at the vanguard of that change. Through innovation and strategic execution, we are securing an early-mover advantage as a leader in the circular and low-carbon solutions market, driving sustainable growth while continuing to deliver from our core business, and actively addressing critical global issues: ending plastic waste, taking climate action, and supporting a thriving society.

Sustainability is central to our strategy

Our corporate strategy defines a roadmap for business transformation, ensuring we continue to deliver long-term value to our stakeholders. Sustainability is integral to this transformation. It is embedded deeply within the three pillars of our strategy, namely in how we:

These strategic pillars are designed to reinforce each other, creating a powerful engine for sustained success.

Investing in our Circular and Low Carbon Solutions (CLCS) business

We are already seeing encouraging results from our work to build a profitable CLCS business. With a full portfolio of high-performance solutions, technical and commercial expertise, and an asset base offering global scale and continuous innovation, we are rapidly becoming the partner of choice for brand owners. In 2024, we increased our recycled and renewable-based polymer volumes by 65% to more than 200,000 metric tons of polymers based on mechanical recycling, chemical recycling, and renewable feedstocks1. This means we are making good progress toward our 2030 goals of producing and marketing at least 2 million metric tons of recycled and renewable-based polymers a year and capturing more than $1 billion of CLCS incremental EBITDA2.

A personal highlight for me this year was laying the foundation stone of our first commercial-scale chemical recycling unit, MoReTec-1, in Cologne, Germany. This signifies our commitment to advancing the circularity of plastic materials on an industrial scale. This facility, set to begin operations in 2026,

is designed to convert hard-to-recycle plastic waste from the equivalent of approximately 1.2 million German citizens each year into valuable raw materials for new offerings. Additionally, we are studying the possibility for a second facility in Houston, U.S., with double the capacity of MoReTec-1.

Unlocking transformation from within

Transforming our business is possible because of the innovation and imagination of the people within LYB. We have already made big strides in transforming our culture through initiatives like the Value Enhancement Program (VEP), which empowers employees to pursue opportunities for continuous value creation. Since the inception of the VEP program, projects completed through this effort have unlocked more than $800M in recurring annual EBITDA3. In 2024, as a result of VEP and other projects, we reduced scope 1 and 2 carbon emissions by 200,000 metric tons, the equivalent of taking approximately 43,400 gasoline powered cars4 off the road a year.

The safety of our employees and contractors is a top priority and has always been a cornerstone of our culture. In 2024, we achieved an industry-leading total recordable incident rate (TRIR) of 0.127, marking our second-best year ever for TRIR. We also celebrated six sites with 10-plus years of no recordable injuries, and our APS segment had record-breaking safety performance, reducing incident rates by 39%, compared to 2023.

The need for collaboration

Transformation doesn't happen in a vacuum. To move from vision to value, we must collaborate with all our stakeholders to bring the best solutions to life. We will continue to engage in open and trustful dialogue across the value chain, positioning our company as a leader in translating the vision for a sustainable, circular economy into tangible change.

To close, I just want to say how much of a privilege it is to lead a team so committed to championing people, striving for excellence and shaping the future. I look forward to our coming successes, and creating lasting value for our shareholders and employees, customers and suppliers.
