press release

**ArcelorMittal announces commencement of the second tranche of its 2025 to 2030 share buyback programme**

**30 June 2026, 10:15 CET**

Further to the announcement on 7 April 2025 of a new share buyback programme (https://corporate.arcelormittal.com/media/news/regulatory-news/arcelormittal-announces-the-commencement-of-a-new-share-buyback-program-over-the-period-2025-2030) covering the period from 2025 to May 2030 (the 'Programme'), ArcelorMittal (the 'Company') today announces the completion of the first tranche of the Programme and the commencement of a second tranche.

The first tranche of the Programme, under which 10 million shares were repurchased at an average purchase price of €49.32 per share, has now been completed in full. The repurchased shares are currently being held in treasury and will be cancelled in due course.

A second tranche of the Programme for up to 10 million shares will commence immediately, under the authorization given by the annual general meeting of shareholders of 6 May 2025.

As communicated at the launch of the Programme, share repurchases are being conducted in tranches through to May 2030. The actual amount of shares to be repurchased in the various tranches will continue to depend on the level of post-dividend free cash flow generated over the period (the Company's defined policy is to return a minimum of 50% of post-dividend annual free cash flow), the continued authorization by shareholders, and market conditions.

The shares acquired under the Programme are intended to:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Reduce ArcelorMittal's share capital;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;• Meet ArcelorMittal's obligations arising from employee share programmes.
