Designated Person financial
"notification of share transaction by a Designated Person (i.e. Directors or Executive Officers)"
A designated person is an individual or entity officially named to carry out specific duties or act on behalf of a company for legal, regulatory or communication purposes — think of them as the company’s appointed point person for a particular task. For investors, knowing who is designated matters because that person has the authority to receive official notices, make filings, handle compliance or speak for the company, which can affect how quickly issues are resolved and who is accountable if problems or insider-information questions arise.
Market Abuse Regulations regulatory
"on market abuse (Market Abuse Regulations), ArcelorMittal announces that notification"
A set of laws and rules designed to stop cheating and unfair tactics in financial markets, such as trading on secret information or manipulating prices. For investors, these regulations matter because they protect fair prices and confidence—like traffic laws that keep drivers honest so everyone can rely on the road—reducing the risk that market moves are driven by hidden or dishonest behavior rather than genuine supply and demand.
