ARM CEO Rene A. Haas Receives RSU Award, Buys 64 Shares

What Happened

• Rene A. Haas, Chief Executive Officer of Arm Holdings plc (ARM), made two transactions reported on Form 4. On August 31, 2026 he acquired 64 ordinary shares (held as ADSs) under the Arm Employee Stock Purchase Plan at $108.33 per share for $6,933. On September 9, 2026 he was reported as receiving 425,000 restricted stock units (RSUs) (derivative award) granted earlier in May 2026 but conditioned on shareholder approval, which was obtained September 9, 2026. The RSU award was reported at $0 because it is contingent on performance milestones.

Key Details

• August 31, 2026: Purchased 64 Ordinary Shares (ADSs) under the Employee Stock Purchase Plan at $108.33/share — total $6,933. (Footnote F2)
• September 9, 2026: Reported grant of 425,000 RSUs (derivative award) priced at $0 (contingent award tied to milestones). (Footnotes F5–F6)
• Each RSU equals the right to 1 Ordinary Share (ADS). (F1, F5)
• Award mechanics: three tranches tied to market-cap milestones — $1.0T by 3/31/2029, $1.5T by 3/31/2030, $2.0T by 3/31/2031; 25% of the award for each interim milestone and 50% for the final milestone; missed interim amounts roll forward; if a milestone is achieved, vesting occurs April 1 two years after that milestone date and remains subject to continued employment. (F6)
• The filing notes a transfer on September 9, 2026 of 57,405 Ordinary Shares from Haas to a grantor retained annuity trust (of which he is trustee). The provided summary does not list a total post-transaction beneficial ownership figure. (F3–F4)
• Filing date: Form 4 filed Sep 10, 2026 reporting activity through Sep 9, 2026 — appears timely (generally due within two business days).

Context

• The 64-share purchase via the employee plan is a standard buy (direct purchase) and is a straightforward acquisition. Purchases can be viewed as a more direct signal of insider buying than grants, though small in dollar size here.
• The 425,000 RSUs are a long-term, performance-contingent award (derivative). Because vesting depends on hitting large market-cap milestones over multiple years and continued employment, these RSUs do not represent immediately tradable shares. They are intended as long-term incentive compensation, not an immediate market bet.
