Pony AI (PONY) VP Mo Luyi Exercises RSUs and Sells 12,425 Shares

What Happened

• Mo Luyi, Vice President of Pony AI (PONY), had restricted stock units (RSUs) vest and settle into a total of 25,006 Class A ordinary shares on 2026-09-25 (943 + 9,063 + 15,000 shares). A portion of the vested shares were surrendered/withheld to satisfy tax obligations (reported as derivative dispositions at $0). On 2026-09-28 she sold 12,425 shares in an open-market transaction at $7.10 per share, generating $88,265 in gross proceeds.
• This consisted of RSU vesting and routine share handling (tax withholding and a sell-to-cover); the open-market sale is not an outright investment purchase and is often routine following vesting.

Key Details

• Transaction dates and prices: RSU settlement on 2026-09-25 (25,006 shares). Open-market sale on 2026-09-28: 12,425 shares at $7.10 each, proceeds $88,265. Derivative dispositions reported at $0 to reflect shares withheld/surrendered for taxes.
• Shares owned after transaction: Not specified in the Form 4 provided.
• Relevant footnotes from the filing:
  • F1: RSUs vested and settled into Class A ordinary shares.
  • F2: The 12,425-share sale was pursuant to a mandatory, non‑discretionary sell‑to‑cover to satisfy income tax liabilities upon vesting.
  • F3–F6: Each RSU equals one Class A share; the awards were granted on 5/15/2023, 12/10/2023, and 12/4/2024 with standard multi‑year vesting schedules (25% at first anniversary, remainder vesting quarterly).
  • F7: The RSU grant cited has no expiration date.
• Filing timeliness: Transaction date listed as 2026-09-25; Form 4 was filed on 2026-09-29. Form 4s are generally required within two business days of the transaction, so this filing appears to have been submitted after that typical window.

Context

• These transactions reflect RSU vesting and related tax-handling (withholding and sell-to-cover) rather than a discretionary purchase or directional bet. When insiders sell shares immediately after vesting to cover taxes, it is routine compensation-related activity and not necessarily a signal about their view of the company’s prospects.
• For retail investors, purchases by insiders tend to be more informative than sell-to-cover sales; this filing documents compensation settlement and tax-related sales rather than a voluntary cash‑raise or large-scale divestiture.
