Insights

Securities Analyst

TL;DR: Insider executed large planned sales under a 10b5-1 plan on 09/18/2025; remaining indirect holdings remain material.

John Colgrove, a director and the company’s Chief Visionary Officer, reported multiple Class A share dispositions tied to a Rule 10b5-1 trading plan adopted January 7, 2025. The filing itemizes two weighted-average sale prices: $87.23 (77,569 shares) and $87.68 (22,431 shares), and a separate reported disposition of 6,478,148 shares. Significant indirect holdings remain via The Colgrove Family Charitable Remainder Trust and multiple family trusts, indicating continued exposure to company equity despite the sales. For investors, planned insider selling of this scale is noteworthy but the 10b5-1 disclosure clarifies intent and timing were prearranged.

Corporate Governance Expert

TL;DR: Sales were processed under an established 10b5-1 plan, reducing ambiguity about insider timing but representing substantial share dispositions.

The Form 4 confirms the transactions were effected pursuant to a Rule 10b5-1 trading plan for The Colgrove Family Charitable Remainder Trust. Using a 10b5-1 plan provides the reporting person an affirmative defense against certain allegations of insider trading because the plan pre-dates the reported trades. The filing also details ongoing indirect ownership through several trusts, which is relevant for assessing long-term aligned ownership and governance influence.
