Horizon Quantum (HQ) CFO Greg Gould — RSU Vesting, Partial Cash Settlement

What Happened

• Greg Gould, Chief Financial Officer of Horizon Quantum Holdings Ltd., had 3,437 restricted stock units (RSUs vest) on September 12, 2026. Those vested RSUs were converted into Class A ordinary shares at no cash cost (reported acquisition price $0.00).
• Of the vested shares, 1,272 were disposed to the company in a cash settlement for a reported proceeds amount of $19,360 (price per share $15.22). The vesting reflects the June 12, 2026 RSU grant.

Key Details

• Grant date and award: June 12, 2026 — Mr. Gould was granted 54,995 unvested RSUs (each represents a contingent right to one Class A ordinary share) at $0.00. The RSUs vest in 16 approximately equal quarterly installments, subject to continued employment.
• Vesting and settlement: September 12, 2026 — 3,437 RSUs vested. The filing reports an acquisition (conversion) of 3,437 shares and a disposition of 1,272 shares to the issuer for $15.22/share, totaling $19,360. The disposition reflects a cash settlement of part of the vested RSUs to cover withholding/taxes.
• Shares owned after transaction: The filing does not specify total shares Mr. Gould owned following these transactions.
• Filing: Form 4 filed September 15, 2026, reporting the June 12 grant and the September 12 vesting/settlement. The filing notes the cash settlement used the last reported sale price ($15.22) as of September 11, 2026.

Context

• These transactions are RSU vesting and a cash settlement to the issuer (common practice to satisfy tax withholding). This is not an open-market sale by the insider.
• The June 12 award is an equity compensation grant (A = award/grant; M = conversion/exercise of derivative; D = disposition to issuer for cash settlement). No cash purchase was made — the shares were issued upon vesting.
