theoretical voting rights financial
"Total number of theoretical voting rights (1): 93,921,863"
Theoretical voting rights are the share of control an investor would have if all possible sources of additional shares—such as stock options, warrants and convertible bonds—were turned into ordinary shares. Investors care because this “what-if” number shows potential dilution of current owners and the maximum voting power others could gain, helping assess control risk and how future actions might change company decisions, like a snapshot of ownership if every coupon were cashed in.
exercisable voting rights financial
"Total number of exercisable voting rights (2): 93,903,288"
Exercisable voting rights are the actual, usable votes attached to a security or position that allow the holder to influence company decisions at shareholder meetings—for example electing the board or approving mergers. They matter to investors because the number of votes someone can cast determines who controls the company and its strategy, similar to having usable tickets at a town meeting rather than placeholders, and can affect share value, takeover risk and how much influence minority holders have.

Universal Registration Document regulatory
"Risk Factors section of the Universal Registration Document filed with the French Financial Markets Authority"
A universal registration document is a single, comprehensive filing that collects a publicly traded company's key disclosures — such as business description, financial statements, risk factors, governance and legal information — into one place for regulators and investors. Think of it as a detailed owner’s manual and scorecard combined: it saves time when the company issues new shares or bonds and helps investors compare, check risks, and make informed decisions without hunting through many separate reports.
Autorité des Marchés Financiers regulatory
"article 223-16 of the French stock-market authorities (Autorité des Marchés Financiers, or “AMF”) General Regulation"
Autorité des marchés financiers is the French-language name for an independent government agency that supervises and enforces rules for securities markets, financial firms, and investor protection. It matters to investors because it requires companies to publish accurate information, polices fraud and insider trading, and can suspend trading or impose penalties—acting like a referee and safety inspector to help markets stay fair and reliable and to give investors confidence and recourse.

(1) The total number of theoretical voting rights (or “gross” voting rights) is used as the basis for calculating the crossing of shareholding thresholds. In accordance with Article 223-11 of the AMF General Regulation, this number is calculated on the basis of all shares to which voting rights are attached, including shares whose voting rights have been suspended. No voting rights attached to AGAP 2016 and AGAP 2017.
(2) The total number of exercisable voting rights (or “net” voting rights) is calculated without taking into account the shares held in treasury by the Company, with suspended voting rights.
