Rhea-AI Filing Summary

Magnetar-related entities entered into variable pre-paid forward sale contracts covering a total of 200,000 shares of CoreWeave, Inc. (CRWV), with settlement obligations on June 19, 2026. The contracts require delivery of up to the pledged shares on the Settlement Date depending on the Nasdaq closing price relative to a $120.00 floor and a $185.00 cap. The reporting group pledged the shares to secure the obligations but retained voting and dividend rights during the pledge term.

The pledged shares are held across several Magnetar vehicles and related entities and were exchanged for aggregate cash proceeds of approximately $23,145,666.82 received from the counterparty when the contracts were entered into. The Form identifies the reporting persons as investment-adviser and affiliated entities and includes disclaimers of beneficial ownership except for pecuniary interests.

Positive

Received substantial upfront cash proceeds of approximately $23,145,666.82 across the contracts
Retained voting and dividend rights in the pledged Class A common stock during the pledge term

Negative

Pledged and encumbered 200,000 Class A shares, creating a contingent delivery obligation on June 19, 2026
Potential transfer of all pledged shares if the Settlement Price is at or below the $120.00 Floor Price

Insights

TL;DR: Magnetar entities monetized 200,000 CoreWeave shares via forward sale contracts, retaining voting and dividend rights while creating a potential delivery obligation on June 19, 2026.

These structures are a common liquidity tool: the reporting entities received cash up front (aggregate about $23.15M) in exchange for contingent obligations to deliver shares depending on the Settlement Price relative to the $120 floor and $185 cap. The contracts are documented as variable pre-paid forward sale contracts and the pledged shares remain subject to the counterparty claim until settlement.

The arrangement preserves voting and dividend rights during the pledge, so governance influence is maintained in the near term. Material items to monitor include the June 19, 2026 Settlement Date and the Settlement Price relative to the stated Floor and Cap, which determine the number of shares deliverable and the ultimate transfer magnitude.

Explanation of Responses:

1. 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.

2. 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 $120.00 (the "Floor Price"), the entity will deliver all Pledged Shares; (b) if the Settlement Price is between the Floor Price and $185.00 (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.
