Insights

Corporate Governance Specialist

Director purchases under a Rule 10b5-1 plan increased indirect holdings to 3,021 shares.

The filing shows Scott Belsky acquired multiple tranches of Class A common stock on 10/01/2025 using a pre-arranged Rule 10b5-1 plan adopted May 29, 2025. Holdings are reported as indirect through the Belsky Family, 2018 Exempt Trust, which is consistent with non‑direct beneficial ownership structures commonly used by insiders.

This is a standard disclosure of scheduled insider purchases; the filing documents compliance with Section 16 reporting and offers per-trade weighted-average prices on request.

Insider Transactions Analyst

Multiple acquisitions totaled a reported increase resulting in 3,021 shares beneficially owned; trade prices ranged roughly $149.86–$161.14.

The Form 4 lists six purchase entries executed the same day with reported weighted-average prices for blocks (examples: $149.8587, $155.08, $161.14). The filer commits to provide detailed trade counts and prices upon request, which supports traceability of execution details.

These are purchases, not disposals, and are tied to an established 10b5-1 plan rather than ad hoc trades.
