CoreWeave, Inc. 4

Brannin McBee, Chief Development Officer of CoreWeave, Inc., converted and sold through related trusts an aggregate of 49,500 shares of CoreWeave Class A Common Stock (via conversion of Class B shares) for roughly $5.2 million in pre-planned open-market transactions while retaining significant indirect holdings.

On August 17, 2026, CoreWeave, Inc. Chief Development Officer Brannin McBee reported a series of insider transactions largely involving conversions of Class B Common Stock into Class A Common Stock held through three related entities (Canis Major 2024 Irrevocable Trust LLC, Canis Major 2025 GRAT, and Canis Minor 2025 GRAT) and immediate open-market sales of the resulting Class A shares under a Rule 10b5-1 trading plan. The Canis Major 2024 Irrevocable Trust converted 3,000 Class B shares into Class A and then sold all 3,000 Class A shares in multiple tranches at weighted-average prices between approximately $101.90 and $109.65, leaving that trust with no remaining Class A shares from this block but 3,000 Class A shares shown as indirectly owned post-conversion in the derivative section. The Canis Major 2025 GRAT converted 40,000 Class B into Class A shares, then sold 36,000 of those Class A shares across nine tranches at weighted-average prices from about $101.90 to $109.65, leaving 4,000 Class A shares from this converted block in the GRAT and a total of 40,000 indirectly owned Class A shares reported after the transaction. The Canis Minor 2025 GRAT similarly converted 12,500 Class B into Class A, then sold 10,500 Class A shares in nine tranches at weighted-average prices in the same general range, leaving 2,000 Class A shares from this block and a total of 12,500 Class A shares indirectly owned post-transaction. Across these trusts, the filing reflects substantial monetization of newly converted high-vote Class B shares into market-traded Class A shares, though the reporting person, directly and through family trusts, still retains significant indirect economic exposure to CoreWeave stock.
