Venturo Brian M 4

What Happened

• Brian M. Venturo, CoreWeave’s Chief Strategy Officer and a director, converted 281,250 shares of Class B common stock into Class A shares and sold all 281,250 converted shares in multiple open‑market transactions on March 4, 2026. The sales were executed at weighted‑average prices of $76.41, $77.49, $78.70, $79.57 and $80.22 across the different lots, producing aggregate proceeds of approximately $22,312,308.
• These were dispositions (sales), not purchases — a conversion of a convertible class followed by immediate sales, which is typically a liquidity event rather than a bullish purchase.

Key Details

• Transaction date: 2026-03-04; Form 4 filed 2026-03-06 (timely — within the Form 4 reporting window).

• Shares sold: 281,250 total in multiple lots; total proceeds ≈ $22,312,308.
• Price details: weighted-average prices by lot: $76.41 (13,000 sh), $77.49 (9,900 sh), $78.70 (46,112 sh), $79.57 (158,138 sh), $80.22 (54,100 sh). Price ranges across lots reported in footnotes run roughly $76.02–$80.66.
• Reported as effected pursuant to a Rule 10b5-1 trading plan (footnote F3).
• Ownership reporting: many reported securities are held in trusts and entities (e.g., YOLO APV Trust, YOLO ECV Trust, Venturo family GRATs, GST Trust), and some held by spouse or household members (see footnotes F2, F9–F15). The filing lists these holdings/vehicles; the excerpt does not show the insider’s total shares owned after the transactions — see the full Form 4 for the post-transaction ownership amount.

Context

• The filing shows a conversion of a derivative/convertible class (Class B) into Class A shares (F1) followed by sales — effectively a conversion + immediate disposition rather than an exercise+hold. When sales are done under a prearranged 10b5‑1 plan (F3), they are typically scheduled trades.
• For retail investors: sales do not by themselves signal company performance — purchases are generally more informative about insider confidence. This filing documents a substantial liquidity event by the insider; check the full Form 4 for exact post-transaction holdings and any additional disclosures.
