Insights

Equity Ownership and Governance Analyst

Large insider conversion and sale of Class A shares by a major holder, with substantial Class B stake retained.

The reporting person, identified as a director and potential large holder, converted 12,500,000 shares of Class B Common Stock into Class A Common Stock on 12/05/2025 and then sold the same 12,500,000 Class A shares at $78 per share on that date. After these transactions, the Form shows 0 Class A shares held directly and 125,630,000 derivative securities (convertible Class B shares) still owned directly. This reflects a shift from direct Class A ownership to continued, sizable exposure through convertible Class B.

The Class B structure allows conversion into Class A on a one-to-one basis at any time, and it will automatically convert upon specified future triggers, including certain transfers, the seven-year anniversary of the IPO closing, or when the reporting person’s and permitted transferees’ Class B holdings fall below a defined threshold. The filing therefore confirms both current liquidity activity in Class A and ongoing control or influence potential via a large remaining Class B position. Key items to watch over the coming years are any further Class B-to-A conversions or transfers, and the timing of the automatic conversion triggers, especially the seven-year IPO anniversary and any reduction in the proportion of Class B held.
