Voting Rights and Capital update

 

National Grid has been notified that 37,686 shares held in Treasury were today transferred to share scheme participants. Following this change, National Grid plc’s registered capital consists of 2,605,885,957 ordinary shares, of which 13,133,370 have been purchased in the market and registered as Treasury Shares; leaving a balance of 2,592,752,587 shares with voting rights.

 

The figure of 2,592,752,587 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 cancellation, or transfer to Treasury, of the shares involved (and any earlier repurchases which remain to be registered).
