Dadswell Charles 4

What Happened
Charles Dadswell, Executive Vice President and General Counsel of Masimo (MASI), shows two derivative dispositions on June 10, 2026 totaling 22,147 units (11,886 + 10,261). No cash price is reported on the Form 4 because these were not open-market sales but adjustments related to the merger with Danaher: Masimo RSUs were assumed by Danaher and converted into Danaher RSUs per the merger agreement, so the Masimo RSU awards were disposed/cancelled and converted rather than sold for cash.

Key Details

• Transaction date: June 10, 2026 (effective date of the merger); Form 4 filed June 12, 2026 (timely).
• Reported dispositions: 11,886 and 10,261 derivative units (total 22,147). Price: N/A (no cash sale reported). Transaction code: D (Disposition to the issuer).
• Conversion mechanics: Per the merger agreement, Masimo RSUs were assumed by Danaher and converted using the formula $180.00 ÷ $183.33 (resulting in a slightly smaller number of Danaher RSUs per Masimo RSU).
• Awards affected: These dispositions represent the unvested portions of RSU grants from Oct 22, 2025 and Mar 6, 2026 (both vest ratably over four years).
• Shares owned after transaction: Not specified on the filing.
• Filing timeliness: Filed June 12, 2026 for June 10 transactions — appears timely (no late-filing flag in the report).

Context
These transactions are derivative adjustments tied to the corporate merger, not open-market sales or purchases; no cash proceeds or trading intent are indicated. For retail investors, note this is a corporate-action conversion of equity awards (RSUs) into the acquiror’s awards per the merger terms, and does not necessarily reflect the insider’s view of the stock.
