Dadswell Charles 4

What Happened

• Charles Dadswell, Masimo's EVP and General Counsel, was granted 10,261 restricted stock units (RSUs) on March 6, 2026. The Form 4 reports the acquisition as a derivative award (price listed as $0 on the Form because RSUs are contingent grants rather than open-market purchases).

Key Details

• Transaction date: 2026-03-06 (reported on Form 4 filed 2026-03-10).
• Instrument: 10,261 RSUs (derivative award); Form shows $0 per share for reporting purposes.
• Vesting: The award vests ratably over four years — 25% on each anniversary of the March 6, 2026 grant date (per footnote).
• Shares owned after transaction: not disclosed in the provided filing details.
• Filing timeliness: Form 4 filed March 10, 2026; appears to be within the normal two-business-day SEC reporting window for Form 4s.
• Footnotes: F1 clarifies each RSU converts to one share upon vesting; F2 describes the four-year, 25% annual vesting schedule.

Context

• RSU grants are a common form of executive compensation and reflect company pay practices rather than an immediate buy or sell signal. These RSUs will convert into shares only as they vest over time, so there is no immediate change in free-floating shares from this grant.
