SulNOx announces that the Company's issued share capital as at the date of this announcement comprises 107,711,393 ordinary shares of 2 pence each with one voting right per share ("Ordinary Shares"). The Company does not hold any shares in treasury and therefore the total number of Ordinary Shares with voting rights in the Company is 107,711,393.  This does not include the shares yet to be admitted to trading following the Exercise of Share Options notified above.

The above figure of 107,711,393 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, the share capital of the Company under the FCA's Disclosure Guidance and Transparency Rules.
