THIS ANNOUNCEMENT CONTAINS INSIDE INFORMATION FOR THE PURPOSES OF REGULATION 11 OF THE MARKET ABUSE (AMENDMENT) (EU EXIT) REGULATIONS 2019/310

 29 June 2023

SulNOx Group Plc (the "Company" or "SulNOx")

Exercise of Share Options

Holding in the Company

(Aquis Stock Exchange: SNOX)

The board of directors of the Company (the "Board") is pleased to announce that Tergeo Limited, a company controlled by Constantine Logothetis, has exercised the options notified earlier today to subscribe for 3,765,300 new ordinary shares of 2 pence each ("Ordinary Shares") at a price of 10 pence per share (the "New Shares"), raising £376,530. It is expected that the proceeds will be utilised for general working capital purposes.

Following the issue of the New Shares, including Ordinary Shares already held by Tergeo Limited, Mr Logothetis will have an interest in a total of 17,569,854 Ordinary Shares, equivalent to 16.31% of the Ordinary Shares, as enlarged by the New Shares.

The New Shares to be allotted will utilise SulNOx's existing unspent share issue authorities and are expected to be admitted to trading on the AQSE Growth Market on 6 July 2023 ("Admission").  On Admission, the Company will have 107,711,393 Ordinary Shares in issue, each with one voting right. The Company does not hold any shares in treasury and therefore the total number of voting rights in the Company is 107,711,393. This figure should be used by shareholders from Admission 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 Company under the FCA's Disclosure Guidance and Transparency Rules.
