Laura Kathleen Bartels, a reporting person for Arm Holdings plc, reported a sale of Arm securities that took place on June 2, 2026. The Form 4 was filed on June 4, 2026, and covers Arm’s ordinary shares, which are held in the form of American Depositary Shares, or ADSs. Each ADS represents one ordinary share of Arm, with each ordinary share having a nominal value of £0.001. Bartels sold 11,306 Arm ADSs at a weighted average price of $392.70 per share. Based on that average price, the transaction represented approximately $4.44 million in gross sale proceeds before any commissions, fees, or taxes. The filing notes that the shares were sold in multiple trades at prices ranging from $392.60 to $393.09. As is customary for weighted-average sale reporting, the filer stated that detailed trade-by-trade pricing information will be provided upon request to the SEC, Arm, or an Arm security holder. The filing does not provide additional derivative-security activity, such as option exercises, restricted stock vesting, or equity award conversions, and the provided text does not state Bartels’s remaining beneficial ownership after the sale. The report was signed on Bartels’s behalf by George Kanelos as attorney-in-fact. The key corporate-governance significance is that the filing discloses a recent insider-related sale of Arm ADSs at a high per-share price, giving investors visibility into trading activity by a company reporting person shortly after the transaction date.
