Insights

Securities Analyst

TL;DR: Insider exercised options and sold the resulting shares; meaningful sale size but retained significant indirect holdings.

The Form 4 documents a routine option exercise of 199,848 shares at $21.995 and a contemporaneous sale of the same number of shares at a weighted average of $110.4323, executed in multiple trades between $109.55 and $110.94. The exercise relates to an option grant dated 05/18/2019 exercisable through 05/18/2028. Post-transaction beneficial ownership totals 325,543 shares comprised of direct and multiple indirect holdings across GRATs and a family trust. The report was filed individually by the reporting person and executed by a POA. For investors, this is a disclosed insider liquidity event but the filing does not provide proceeds or tax details.

Corporate Governance Expert

TL;DR: The disclosure is complete and procedural; transactions appear consistent with option exercise and sale protocols.

The Form 4 clearly identifies the reporting person as SR VP & CFO and lists the nature of indirect holdings by vehicle (GRATs and family trust). The filing includes explanatory notes that the sale price is a weighted average and that some shares transferred from a 2024 GRAT since the last Form 4. Signature by a POA on 08/25/2025 is indicated. There are no governance red flags in the document itself; it records a standard executive exercise-and-sell transaction with remaining beneficial ownership disclosed.
