NIOX Group plc
Exercise of Options, Director Dealing and TVR
17 April 2026
NIOX Group plc (the "Company") (AIM: NIOX) announces that on 16 April 2026 Ian Johnson, Jonathan Emms and Sarah Duncan (the "Directors") exercised share options in the Company. The options were awarded under the terms of the Company's Performance Share Plans.
These awards were satisfied by issuing 1,466,320 ordinary shares of 0.08 pence each in the Company ("Ordinary Shares"). The Ordinary Shares issued are subject to an existing block admission and rank pari passu with the Company's existing Ordinary Shares.
Furthermore, the Company notifies that Jonathan Emms and Sarah Duncan sold a sufficient number of Ordinary Shares to satisfy the tax liability and other costs arising on exercise. As a result, 489,885 Ordinary Shares were sold on behalf of those individuals at 56.4 pence per Ordinary Share.
Further details of the exercise and sale (together the "Transaction") are detailed below:
| Number of Ordinary Shares held prior to the Transaction | Number of share options exercised | Number of Ordinary Shares sold | Number of Ordinary Shares held subsequent to the Transaction | Total interest in the issued share capital |
Ian Johnson | 4,623,180 | 585,108 | - | 5,208,288 | 1.24% |
Jonathan Emms | 3,399,076 | 585,108 | 325,273 | 3,658,911 | 0.87% |
Sarah Duncan | 5,522 | 296,104 | 164,612 | 137,014 | 0.03% |
Total voting rights
Additionally, since the last total voting rights disclosure, certain employees exercised options over a total of 872,681 Ordinary Shares of 0.08p ("Ordinary Shares") under the Company's share option schemes.
Following this, the Company's issued share capital now consists of 420,413,454 Ordinary Shares, each carrying one voting right. This number 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 Company under the FCA's Disclosure and Transparency Rules.
