Dear friends of the company,

Metals for Progress: Driving Sustainable Growth

"Metals for Progress: Driving Sustainable Growth" - our company strategy clearly expresses that Aurubis views sustainability as an essential part of our Group's conduct and business activities. We are committed to the responsible handling of the resources we use to create value in the form of our metals - for an innovative and sustainable world. Because our products are the key to the mobility and energy transition, as well as to digitalization.

We feel it is essential to counteract the impacts of ongoing climate change through our business activities and to contribute to greater resource efficiency and better health protection. This objective is reflected in the ten principles related to human rights, labor, environmental protection, and anti-corruption that are part of the United Nations Global Compact (UNGC), which we have been party to since 2014.

Our Sustainability Report details just how sharp our sustainability focus is at Aurubis. As in previous years, this report is based on the internationally recognized standards of the Global Reporting Initiative (GRI). We have also linked our strategic topics to the UN Sustainable Development Goals (SDGs), goals that we are helping achieve.

As we expand our industry leadership role in sustainability, we are targeting nine action areas under theEconomy,People andEnvironment focus areas. We have defined concrete and ambitious targets for each of these action areas that we aim to achieve by 2030. This is how we are making our progress in sustainability transparent and quantifiable.

In the People sustainability area, we are demonstrating how, as a future-oriented employer, Aurubis creates an environment in which employees work together in trust and safety. We set great store in high-quality vocational training and continuing education, and foster diversity and social engagement. Just one of many examples of our progress in this area: To

raise employee awareness of human rights and anti-discrimination, we developed a Group-wide training concept that has already reached over 90 % of administrative staff.

The Environment sustainability area encompases the important goal of achieving carbon-neutral production well before 2050. At the end of 2019, Aurubis joined the UN Global Compact Business Ambition for 1.5°C, thereby pledging our commitment to work on science-based CO2 reduction targets. The Science Based Targets initiative (SBTi) validated these CO2 reduction targets in 2021, thus confirming that we are contributing to limiting global warming to 1.5°C in line with the Paris Climate Agreement. Our life cycle assessments show just how far down the path to carbon-neutral metal processing we have come, thanks to a wide range of measures: Today we are already producing many of our metals with less than half the global average CO2 footprint.

As a multimetal company, we source raw materials from many places around the globe. So responsibility in the supply chain is deeply rooted in the Economy sustainability area. To fulfill our due diligence for

a responsible and sustainable supply chain, all our business partners undergo our comprehensive Business Partner Screening based on the principles of the Organisation for Economic Cooperation and Development (OECD). As the most efficient and sustainable smelter network in the world, we believe it is important to offer comprehensive value chain solutions for the circular economy. With our multimetal recycling, we are making an important contribution to the efficient and environmentally friendly use of valuable resources. The construction of Aurubis Richmond, the largest multimetal recycling plant in the US with a processing capacity of 180,000 tons of valuable materials per year, is impressive proof of our approach.

At Aurubis, we are absolutely certain: With our metals, we will continue to shape the future and grow - as a sustainability leader in our industry. Aurubis will resolutely carry on down this path and we look forward to your continued support.
