National Grid plc (National Grid)
Voting Rights and Capital update
National Grid has today been notified that 91,376 shares held in Treasury were transferred to share scheme participants on 13 May. Following this change, and after transfers into treasury registered as part of the ongoing share repurchase programme, National Grid plc's registered capital at close of 14 May 2008 consists of 2,581,913,516 ordinary shares, of which 81,777,229 have been purchased in the market and registered as Treasury Shares; leaving a balance of 2,500,136,287 shares with voting rights.
The figure of 2,500,136,287 may be used by shareholders as the denominator for the calculations by which they will determine if they are required to notify their interest in, or a change to their interest in, National Grid plc under the FSA's 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).
