treasury shares financial

"Following the share buybacks detailed above, the Company holds in total 19,224,908 treasury shares"

Treasury shares are a company’s own stock that it has repurchased and keeps on its books instead of canceling or leaving in the hands of outside investors. Think of them like coupons a business puts back in a drawer: they don’t vote or receive dividends while held, but they can be reissued later for employee pay or fundraising. For investors this matters because buybacks change the number of shares that count toward earnings and ownership, can boost per‑share metrics, and use corporate cash that might otherwise go to growth or dividends.

market abuse regulation regulatory

"The purpose of these transactions under article 5(2) of Regulation (EU) 596/2014 (the Market Abuse Regulation)"

Market abuse regulation consists of laws and rules designed to prevent dishonest or manipulative practices in financial markets. It aims to ensure fair and transparent trading, so investors can trust that markets operate honestly, much like rules that keep a game fair. By reducing unfair advantages, it helps protect investor confidence and promotes healthy, efficient markets.

lei regulatory

"LEI: 213800Z8NOHIKRI42W10"

A Legal Entity Identifier (LEI) is a unique 20-character code assigned to a company or organization that participates in financial markets, like a corporate passport number. It helps investors and regulators unambiguously identify counterparties across databases and transactions, reducing confusion much like using a vehicle identification number to track a car’s history; clearer identification improves transparency, risk monitoring, and regulatory reporting.

isin financial

"ordinary shares of STMicroelectronics (ISIN: NL0000226223)"

A 12-character International Securities Identification Number (ISIN) is a unique code that acts like a passport for a specific stock, bond or other tradable security so it can be identified worldwide. Investors and systems use it to ensure they are buying, selling and tracking the exact same instrument across exchanges and data feeds, which prevents costly mix-ups and makes portfolio reporting, settlement and regulatory checks simpler and more reliable.
