Insights

Equity analyst

Pre-planned insider sales funded by conversions, with large stakes retained.

Brannin McBee converted 143,750 Class B shares into Class A and sold the same number of Class A shares in multiple open-market trades. The reported weighted-average sale prices span the low-to-high $80 range per share, reflecting a sizable but structured liquidity event.

The transactions were executed under a Rule 10b5-1 trading plan adopted on November 17, 2025, indicating they were pre-scheduled rather than opportunistic. Following the sales, McBee still directly owns 248,664 Class A shares and 7,791,660 Class B shares, plus additional indirect Class B holdings via a 2022 irrevocable trust and his spouse. This suggests the sales represent a minority portion of his overall economic exposure, consistent with routine diversification rather than a major change in alignment.
