· Issued by NIOX Group PLC via RNS

Summary by 6ix AI

NIOX Group plc has applied to cancel the block listings (pools of shares pre-approved for trading so they can be issued under employee share schemes) for three closed schemes covering 938,521 ordinary shares of £0.0008 each, as at September 30, 2026. All outstanding options under these schemes have been exercised or have lapsed.

Key details

  • The three schemes are the Circassia 2016 Performance Share Plan Scheme (499,514 unissued shares), the NIOX 2023 Deferred Share Bonus Plan (129,374) and the Circassia 2020 Save As You Earn Scheme (UK) (309,633). Save As You Earn is an employee share-savings scheme.
  • NIOX made no share issues under these three plans since its last block listing return on March 31, 2026, and says no further shares will be issued under these block listings.
  • In its interim return for six active schemes for April 1, 2026 to September 30, 2026, the unissued balance went from 7,224,317 shares to 4,432,457 shares.
  • Shares issued in that period were 122,000 under the NIOX 2020 Performance Share Plan Scheme, 205,704 under the NIOX 2022 Performance Share Plan Scheme and 2,464,156 under the NIOX 2023 Performance Share Plan Scheme.
  • NIOX shares trade on AIM, the London Stock Exchange's market for smaller companies, and the return is made under AIM rules.
