Pennon Group's Issued Share Capital and Treasury Share Position at 31 October 2026

The announcement, signed by Emma Hough, Interim Group General Counsel and Company Secretary, confirms that Pennon Group's issued share capital as at 31 October 2026 totals 692,245,048 ordinary shares, each carrying a nominal value of 61.05 pence. Of these, 5,628 shares are held in treasury and therefore carry no voting rights. Subtracting the treasury shares from the total issued capital yields the confirmed voting rights figure of 692,239,420. This distinction between issued share capital and voting shares is significant for regulatory compliance purposes, as treasury shares do not count towards shareholder notification thresholds under FCA rules.

How Shareholders Must Use the 692,239,420 Denominator Under FCA Transparency Rules

Under FCA Disclosure Guidance and Transparency Rule 5.6.1 R, listed companies are required to publish their total voting rights at the end of each calendar month in which a change occurs, enabling shareholders to calculate their proportional interests accurately. The confirmed denominator of 692,239,420 must be used by any shareholder determining whether their holding has crossed, or is approaching, a notifiable threshold. Investors whose interests in Pennon Group plc meet or exceed applicable percentage thresholds are required to submit a notification to both the company and the FCA under the DTR regime.
