TeraWulf Inc. (NASDAQ: WULF) has successfully completed a $1 billion convertible notes offering after the full exercise of the greenshoe option by initial purchasers. The company, which operates as a vertically integrated, zero-carbon digital infrastructure provider, announced that the initial purchasers exercised their option to buy an additional $150 million of notes, bringing the total offering to the full $1 billion amount.

The net proceeds from the offering amounted to approximately $975.2 million after accounting for offering expenses.

The company's leadership team, comprised of veteran energy infrastructure entrepreneurs, brings substantial expertise to the execution of this expansion strategy.
