Insights

Financial Analyst

TL;DR: Insider exercised options and sold shares under a pre-existing 10b5-1 plan; transactions are routine with no new corporate disclosures.

The Form 4 shows Michael Benkowitz exercising two option series (14,625 and 7,875 options) and the subsequent sale of resulting shares in multiple tranches at market prices between $405.54 and $419.63. Transactions were executed pursuant to a Rule 10b5-1 trading plan dated June 3, 2025, which provides an affirmative defense for scheduled trades. Shares are held in trusts where the reporting person is a beneficiary and exercises either shared or sole voting and investment power. The filing provides trade-level weighted-average prices and indicates willingness to provide full trade details on request.

Corporate Governance Expert

TL;DR: Transactions appear compliant with 10b5-1 procedures and reflect trust-held insider dispositions rather than ad hoc sales.

The disclosure identifies a Rule 10b5-1 plan as the mechanism for the option exercises and sales, reducing concerns about timing. Beneficial ownership is indirect via trusts with differing control arrangements: one trust where the reporting person and spouse are co-trustees and another where he has sole investment and voting power. The filing is signed under power of attorney and includes standard explanatory footnotes about weighted-average pricing across multiple trades.
