Maguire Scott Andrew 4

What Happened

• Scott Andrew Maguire, Chief Operating Officer of On Holding AG (ONON), had 3,771 restricted stock units (RSUs) vest and settle into shares on 2026-06-05 (acquired at $0). Portions of those shares (1,551; 1,699; and 521) were recorded as disposed on 2026-06-05 at $0 (derivative disposals, consistent with tax withholding or settlement mechanics). On 2026-06-08 he sold 1,534 shares in an open-market transaction at $36.08 for proceeds of $55,353.
• The activity includes both an award settlement (RSU vesting) and a subsequent open-market sale. Awards/withholdings are routine for compensation vesting; the open-market sale is a realized disposition of shares.

Key Details

• Transaction dates and prices:
  • 2026-06-05: 3,771 shares acquired on RSU settlement at $0 (F1–F2).
  • 2026-06-05: 1,551; 1,699; and 521 shares disposed at $0 (derivative disposals — likely tax withholding).
  • 2026-06-08: 1,534 shares sold open market @ $36.08, proceeds $55,353.
• Shares owned after the transactions: Not specified in the Form 4 filing.
• Notable footnotes: RSUs vest/settle at no cost (F1); each RSU equals one Class A share (F2). Grants referenced: 06/23/2025 (vests quarterly through 06/05/2028), 03/23/2026 and 04/01/2026 (vest quarterly through 03/05/2029) (F3–F5).
• Filing timeliness: The filing date is 2026-06-09. The 06/05 settlement was reported four days later, which may be outside the standard two-business-day Form 4 reporting window for that transaction.

Context

• These transactions reflect RSU vesting and routine settlement/withholding. The $0 disposals are consistent with shares withheld to satisfy tax obligations when RSUs vest (not market sales).
• The single open-market sale (1,534 shares for ~$55K) is a realized sale, not necessarily a signal of broader insider sentiment — purchases are typically more informative about bullishness.
• No 10% owner or 10b5-1 plan is indicated in the filing.
