Director · TERAWULF INC. (WULF)
This is the public record of open-market stock transactions Michael C. Bucella has reported to the SEC on Form 4 as Director of TERAWULF INC. (WULF). Every figure below is the reported share count multiplied by the reported price, so the dollar amounts are exact disclosed values rather than estimates. It is a record of what has been filed, not a portfolio or a recommendation, and insider selling in particular is routine and rarely a signal on its own.
