beneficial ownership financial

"disclaims beneficial ownership of these shares of Common Stock"

Beneficial ownership means the person or entity that actually enjoys the benefits of owning shares or other assets — such as receiving dividends, voting rights, or price gains — even if the legal title is held in another name. For investors it matters because knowing who truly controls and profits from a company reveals who can influence decisions, exposes potential conflicts of interest or hidden concentration of power, and affects transparency and risk in the stock.

pecuniary interest financial

"except to the extent of its or his pecuniary interest therein"

indirect financial

How many CoreWeave (CRWV) warrants were sold and at what price?

Magnetar-associated funds sold warrants over 100,000 underlying Class A shares at a reported per-share price of $105.4505. Individual sales covered 26,014, 23,128, and 50,858 underlying shares, all on 2026-08-13.

The reported warrants have an exercise price of $1.5495 per underlying Class A share, with expiration dates on 2029-10-17 and 2029-11-15. These warrants provide the right to buy CoreWeave Class A Common Stock at that price until expiry.

Who actually holds the CoreWeave (CRWV) warrants sold in this filing?

The warrants sold are held directly by specific funds, including Magnetar Alpha Star Fund LLC, Magnetar SC Fund Ltd, and Magnetar Xing He Master Fund Ltd. Magnetar Financial and related entities report indirect ownership and disclaim beneficial ownership beyond their pecuniary interest.

Were the CoreWeave (CRWV) warrant sales under a Rule 10b5-1 plan?

The filing’s Rule 10b5-1 checkbox is not marked as affirmative, and no footnote states the sales were made under a Rule 10b5-1 trading plan. The transactions are therefore reported without an associated pre-arranged trading plan designation.

Do Magnetar entities still hold CoreWeave (CRWV) derivative positions after these sales?

Yes. The derivative holdings table lists multiple remaining warrant positions with exercise price $1.5495 and expirations in 2029, including positions over 114,505 and 229,011 underlying shares, all reported as indirectly owned through various Magnetar-managed funds.
