Case Study: ArcelorMittal achieves streamlined SEC and European reporting with Workiva

ArcelorMittal Builds a Reporting Process as Strong as Steel

ArcelorMittal, the global steel and mining leader, needed a better way to meet complex regulatory requirements as a foreign private issuer—most pressingly SEC 20‑F XBRL tagging—while reducing manual work, improving usability and strengthening customer service across multiple filings and reports.

They adopted Workiva for its XBRL expertise and user‑friendly cloud platform, with role‑based training that sped adoption. The solution enabled real‑time collaboration with auditors and lawyers, linked European and SEC reports to eliminate duplicate work, simplified EDGAR filing and supported remote work during COVID‑19—cutting rework, emails and version issues and saving about a week during the annual reporting season.
