Shareholders of Fonix Plc

The most recently available shareholder data for Fonix Plc (dated 21 September 2026) discloses five shareholding entries. The largest is Ganton Limited, recorded holding approximately 35.5% of ordinary shares (35,535,666 shares of GBP 0.001 each); Ganton Limited is publicly identified as an investment vehicle of company co-founder and non-executive director William Neale. Other disclosed holders include Robert Weisz, the company’s co-founder and Chief Executive Officer, recorded at approximately 11.6%, Magnolia Capital Limited at approximately 2.3%, and Stephen George, recorded across two entries totalling approximately 1.5%. As an AIM-listed company, Fonix Plc’s complete shareholder base also includes institutional and retail holders not captured in this dataset; separate market-data sources report that institutional shareholders collectively hold a majority of the company’s shares.

Data availability

Availability is partial. The share-register data above is dated 21 September 2026, but the statutory Persons with Significant Control (PSC) register held at Companies House currently records no active PSC statement, a position in force since 23 June 2022 — the date on which Ganton Limited’s previously notified holding (more than 25% but not more than 50% of shares and voting rights) ceased to be registrable. This is an unreconciled discrepancy between the two sources; as a result, no current ultimate beneficial owner can be reliably confirmed from public filings, and the shareholding percentages above should be read as informational share-register data rather than a statutory beneficial-ownership disclosure.

Group Structure

Group structure of Fonix Plc

Fonix Plc is the ultimate parent of its group; no parent or controlling entity is disclosed above it. One verified direct subsidiary has been identified: Fonix GmbH, registered in Zug, Switzerland, wholly owned by Fonix Plc and established to support the company’s Swiss market entry. A same-named entity, Fonix Mobile Plc, is registered in Dublin, Ireland, and its incorporation date coincides with Fonix’s public announcement of its launch into the Irish market, but the Irish registry record does not itself disclose parent-company information, so this relationship is treated as probable rather than registry-confirmed. Information is dated 22 September 2026 and combines UK, Swiss and Irish registry data; further overseas entities may exist to support newer markets such as Portugal and France that are not yet reflected in public registry data.

Fonix GmbH Switzerland CHE-131.998.330 Direct subsidiary 100% (20,000 of 20,000 shares of CHF 1.00) Active 22 September 2026
Fonix Mobile Plc Ireland 909822 Possible relationship (unverified as subsidiary) Ownership percentage not disclosed Active (Normal) 22 September 2026

Recent structural changes

  • Fonix GmbH incorporated in Zug, Switzerland, 10 September 2025, as a wholly owned subsidiary to support Swiss market entry.
  • An entity named Fonix Mobile Plc was incorporated in Dublin, Ireland, 11 July 2022, coinciding with Fonix’s announced launch into the Republic of Ireland.

Data availability

Partial. The Swiss subsidiary relationship is confirmed directly by the Swiss commercial register, which names Fonix Plc (05836806, London) as sole shareholder of Fonix GmbH. The Irish entity’s own registry record does not disclose beneficial or parent-company information, so that relationship could not be independently confirmed from an official filing.
