CoreWeave, Inc. 4

Brannin McBee, Chief Development Officer of CoreWeave, Inc., converted Class B into Class A shares in two GRATs and then sold most of the resulting Class A stock, along with small additional sales from a family trust, at prices around $89–$93 per share on August 10, 2026.

On August 10, 2026, CoreWeave, Inc. Chief Development Officer Brannin McBee reported a series of insider transactions primarily involving trusts and GRAT vehicles he controls or is affiliated with. Two conversions of Class B Common Stock into Class A Common Stock occurred: 40,000 shares held by the Canis Major 2025 GRAT and 12,500 shares held by the Canis Minor 2025 GRAT were converted into an equal number of Class A shares. Immediately following these conversions, the Canis Major 2025 GRAT sold an aggregate 41,?000 shares of Class A Common Stock (in multiple tranches of 13,149, 14,765, 8,798, 2,876, 252, and 160 shares) at weighted average prices between approximately $88.70 and $93.50, fully reducing that GRAT’s reported Class A position from 40,000 shares to zero as of this part of the filing. The Canis Minor 2025 GRAT, after converting 12,500 Class B shares, sold a total of 12,?898 shares of Class A stock (4,110, 4,612, 2,750, 899, 79, and 50 shares) at similar weighted average price ranges, likewise taking its Class A balance from 12,500 to zero. In addition, the Canis Major SM Trust, an irrevocable trust benefiting the reporting person’s minor child, sold a small aggregate amount of Class A stock (164, 196, 106, 33, and 1 share) at prices between roughly $88.71 and $92.53, modestly trimming its holdings from 49,500 shares to 49,000 shares. All sales were executed under a Rule 10b5‑1 trading plan adopted on March 5, 2026, and many of the reported prices represent volume-weighted average prices for multiple trades within specified intraday ranges. McBee continues to report substantial indirect ownership of both Class B and, upon conversion, Class A shares through multiple GRATs and family trusts, including large positions in the Canis Major 2025 Family Trust LLC, Canis Minor 2025 Family Trust LLC, and 2026 GRAT entities.
