Voting rights and capital – update

 

National Grid plc’s registered ordinary share capital as at close of 29 February 2008 consisted of 2,581,913,516 shares, of which 54,432,175 have been purchased in the market and registered as treasury shares, leaving a balance of 2,527,481,341 shares with voting rights.

 

The figure of 2,527,481,341 may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interests in, or a change to their interest in, National Grid plc under the Disclosure and Transparency Rules.

 

Note: This notification confirms actual capital as recorded on the register at the above date, allowing for changes recorded since the last notification. National Grid is currently undertaking a share repurchase programme. Where repurchases are made, separate covering announcements will, as required, identify numbers being repurchased and the supporting details indicate resultant share capital after market settlement and transfer to Treasury, or cancellation, of the shares involved (and any earlier repurchases which remain to be registered).
