Euronext includes Aperam in its new BEL® ESG stock market index

Luxembourg, 16 February 2023 (09:00 CET) - Aperam is proud to announce that we are now a member of the newly announced BEL® ESG stock market index .

Euronext today announced the launch of the BEL® ESG index, a new index identifying and tracking the companies within the BEL® 20 and the BEL® Mid indices that have demonstrated the best ESG practices.

The BEL® ESG Index is designed to facilitate the adoption of mainstream ESG investment solutions by investors. It is the fifth ESG Index variant for national blue-chip indices, following the launch of the CAC® 40 ESG (France), the MIB® ESG (Italy), the AEX® ESG (The Netherlands) and the OBX® ESG (Norway).

governance (ESG) performance. It is based on Sustainalytics' ESG data and structured according to Febelfin's Towards Sustainability label.

With this new index, Euronext aims to respond to the growing market demand for sustainable investment instruments. Investors can thus find their way to those companies that focus on a more sustainable future by combining economic results with sustainability considerations.

We view this as an important first recognition of our efforts in placing sustainability at the center of our strategy and providing transparent communication on our targets and practices.

Aperam fully integrates into its strategy the need for a more circular economy, as demonstrated with the creation of our new segment Recycling and Renewables and the acquisition of the former ELG (a major player in the global stainless scrap recycling market) in December 2021. Together with our FSC®-certified forestry it places sustainability at the heart of Aperam's strategy. We are committed to become carbon neutral by 2050, based on energy efficiency improvements and green energy production and sourcing.

Our annually published Sustainability Report (link) provides additional valuable insights to a variety of stakeholders.
