What Happened
Laura Kathleen Bartels, Chief Accounting Officer of ARM, had restricted stock units (RSUs) vest and completed conversion/exercise steps on May 15, 2026. Several derivative conversions (3,588; 862; and 2,308 ADSs) were processed and, to satisfy tax withholding on vesting, 3,383 ADSs were withheld/sold at $209.16 per ADS for proceeds of $707,588. In addition, Bartels received new RSU awards totalling 86,215 RSUs (16,645 and 69,570 RSUs) granted effective May 15, 2026.

Key Details

  • Transaction date: May 15, 2026; Form 4 filed May 19, 2026 (filed 4 days after the transactions; Form 4s are generally due within 2 business days).
  • Sale/withholding: 3,383 ADSs withheld/ disposed at $209.16 each for $707,588 (tax withholding). Transaction code F (payment of exercise price or tax liability).
  • Exercises/conversions: Derivative conversions/exercises processed for 3,588; 862; and 2,308 ADSs (transaction code M). Some exercise/conversion items reported with $0 cash value (derivative conversion to shares).
  • Grants: Two new RSU awards granted effective May 15, 2026 totaling 86,215 RSUs (transaction code A; $0.00 per share because these are awards).
  • Footnotes of note:
    • F1: ARM ordinary shares are held as ADSs; 1 ADS = 1 ordinary share.
    • F2–F5/F7–F8: Vesting schedules: these awards were granted in 2023–2026 with standard time-based vesting (some earlier awards fully vested May 15, 2026).
    • F6: Ordinary shares were withheld to satisfy tax withholding requirements on RSU vesting.
  • Shares owned after the transactions: not stated in the provided filing.

Context

  • This was primarily a vesting/tax-withholding event, not an open-market sale or purchase by the insider. When RSUs vest, companies commonly withhold or sell a portion of shares to cover taxes — that's what's reported here (routine corporate administration).
  • For retail investors: awards and vesting are routine compensation events; the only cash flow reported is the tax-withholding disposal of 3,383 ADSs for ~$707.6k.
  • The filing date suggests the Form 4 was submitted a few days after the transaction date; investors may note the timing but this type of filing typically documents routine vesting and withholding rather than discretionary trading.
