What Happened

Ritchie Garth, a director of Arqit Quantum Inc. (ARQQ), reported multiple RSU exercises/conversions on April 1, 2026 and an open-market sale on April 2, 2026. The filing shows several RSU conversions (exercise/conversion, code M) recorded at $0.00 per share on April 1. On April 2 he sold 512 shares in the open market at $13.25 per share for total gross proceeds of approximately $6,782.

The filing includes zero-dollar derivative dispositions (also dated April 1), consistent with RSU conversions and related transfers noted in the footnotes.

Key Details

  • Primary sale: 512 shares sold on 2026-04-02 at $13.25 per share — proceeds ~$6,782. (Transaction code S)
  • RSU conversions: Multiple exercise/conversion entries on 2026-04-01 at $0.00 (transaction code M); specific line items reported: 250, 50, 250 and 501 shares. Matching zero-dollar derivative dispositions also reported on 2026-04-01.
  • Shares owned after transaction: Not specified in the provided filing excerpt.
  • Footnotes:
    • F1: RSUs convert one-for-one into ARQQ ordinary shares.
    • F2–F5: Describe varying RSU vesting schedules; F5 notes 501 RSUs vested on April 1, 2026.

Context

  • The "M" (exercise/conversion) entries reflect RSUs converting into common shares (at $0.00 per share). The filing also shows zero-dollar derivative disposals on the same date, which in similar filings often reflect transfers or tax-withholding related to vesting — the filing’s footnotes describe the vesting schedules.
  • The sale was an open-market disposition the day after the conversions; filings like this are routine reporting of insider vesting and subsequent sale and should be viewed as factual (not a direct statement of sentiment).
