(1) According to Art. 223- 11 of the AMF General Regulations the theoretical (or gross) number of voting rights is used on the basis of all shares with voting rights, including shares temporarily deprived of voting rights (treasury shares, liquidity contract treasury shares), but excluding shares which have no voting rights (preferred shares).

(2) The net number of voting rights (or voting rights “exercisable at a Shareholders’ Meeting”) is calculated by excluding shares without voting rights. It is provided for public information.

The by-laws of Vallourec contain a provision imposing an obligation to declare crossing thresholds in addition to those relating to legal thresholds.
