McBee executes a planned convert-and-sell of 481,245 CoreWeave shares under a Rule 10b5-1 plan.

Chief Development Officer Brannin McBee oversaw conversions of 481,245 shares of Class B into Class A at $0.00 per share on March 9, 2026. These conversions occurred directly and through a spouse, a 2022 irrevocable trust, and the Canis Major 2025 GRAT, reflecting movements from high-vote Class B into freely tradable Class A.

The filing then records open-market sales of 481,245 Class A shares at weighted average prices between about $71.02 and $74.48, designated as sales under a Rule 10b5-1 trading plan adopted on November 17, 2025. Such plans indicate these trades were pre-scheduled, which generally reduces the informational value of the timing.

After the transactions, McBee holds 248,664 Class A shares directly while still retaining multi-million-share positions in Class B directly and via related entities. This pattern resembles a routine liquidity event and portfolio rebalancing rather than a full exit, with overall impact depending on company-wide share counts not shown in this data.
