Insights
Institutional holders report shared voting and dispositive power over 7,251,900 shares (7.77%).
The filing shows Magnetar Financial, Magnetar Capital Partners, Supernova Management, and David J. Snyderman are joint reporting persons with shared voting and shared dispositive power over the same 7,251,900 shares. The statement attributes holdings across multiple Magnetar funds by name and exact per-fund share counts.
Impact depends on whether the 4,126,900 issuable shares from warrants and notes are issued; subsequent filings will show any change in percent ownership or voting influence.
Disclosure quantifies position and perimeter of potential dilution from convertible instruments.
The schedule provides per-fund allocations (for example, 1,339,683 shares for Constellation Master Fund and 1,506,757 for Lake Credit Fund) and identifies 205,000 warrantholders' shares plus 3,921,900 convertible-note shares as issuable. The filing ties percent ownership to an April 6, 2026 outstanding-share count of 89,177,103.
Whether dilution occurs depends on actual issuance of warrants/notes; cash‑flow treatment and issuance timing are not stated here.

beneficially ownedregulatory
"As of March 31, 2026, each of the Reporting Persons held 7,251,900 shares of Common Stock"
Beneficially owned describes securities or assets where a person has the economic rights and control—such as the right to receive dividends and to direct voting—even if legal title is held in another name. Think of it like having the keys and using a car that’s registered to someone else: you get the benefits and make decisions. Investors care because beneficial ownership reveals who truly controls value and voting power, affecting corporate decisions and takeover dynamics.

"205,000 shares of Common Stock issuable upon exercise of the Warrants"
Warrants are special documents that give you the right to buy a company's stock at a set price before a certain date. They are often used as a way for companies to attract investors or raise money, and their value can increase if the company's stock price goes up.
