F1 The entity holding the indicated number of shares of Class A common stock (the "Common Stock") of CoreWeave Inc. (the "Issuer") entered into a variable pre-paid forward sale contract with a third party counterparty. The contract obligates the entity to deliver to the counterparty up to the indicated number of shares on June 19, 2026 (the "Settlement Date"). The entity pledged the indicated number of shares, as reported in Column 5 (the "Pledged Shares"), to the counterparty to secure its obligations under the contract and retained voting and dividend rights in the Pledged Securities during the term of the pledge.
F2 The number of shares deliverable to the counterparty on the Settlement Date is to be determined as follows: (a) if the price at the Nasdaq closing time on June 18, 2026 (the "Settlement Price") is less than or equal to $130.00 (the "Floor Price"), the entity will deliver all Pledged Shares; (b) if the Settlement Price is between the Floor Price and $200.00 (the "Cap Price"), the entity will deliver a number of shares having a value (based on the Settlement Price) equal to the number of Pledged Shares multiplied by the Floor Price; and (c) if the Settlement Price is greater than the Cap Price, the entity will deliver a number of shares having a value (based on the Settlement Price) equal to the number of Pledged Shares multiplied by the sum of the Settlement Price and the difference between Cap Price and the Floor Price.
