Arm Holdings Director Ronald Fisher Receives 1,531 RSUs Vesting in 2027

This Form 4 filing reports that Ronald D. Fisher, a director of Arm Holdings plc, received 1,531 restricted stock units (RSUs) on May 15, 2026. Each RSU represents the right to receive one Ordinary Share (held as an American Depositary Share) following vesting. The RSUs will fully vest on May 15, 2027, subject to Fisher's continued service on the Board of Directors. However, the ADSs will not be delivered until the termination of Fisher's board service, as he has elected to defer delivery. Following this transaction, Fisher holds a total of 5,802 RSUs. The transaction was reported by attorney-in-fact George Kanelos on May 19, 2026. This represents a standard equity compensation arrangement for non-employee directors.
