Summary
TeraWulf executed two transformational transactions that reshape its business model and capital structure. The company signed a 20-year lease with Anthropic—a leading AI company—to provide 401 MW of power capacity at its Justified Data campus in Kentucky, generating approximately $19 billion in contracted revenue over the initial term with investment-grade credit backing.
Simultaneously, TeraWulf is exiting its Abernathy Joint Venture by selling its 50.1% stake to partner Fluidstack for approximately $530 million, monetizing its ~$450 million investment at a premium. The dual transactions reflect a deliberate strategic shift: TeraWulf is moving away from joint venture structures toward wholly owned infrastructure where it controls customer relationships and operations directly.
The $530 million in proceeds from Abernathy (structured in three installments through April 2027) will be redeployed into wholly owned AI infrastructure opportunities. With the Anthropic lease providing two decades of revenue visibility starting in late 2027 and the Abernathy sale unlocking capital immediately, TeraWulf has positioned itself for sustained growth in the AI data center market while simplifying its financial reporting through elimination of joint venture accounting. Retail investors should watch for execution milestones on the Justified Data campus buildout through 2027-2028 and management's capital allocation decisions with the Abernathy proceeds.
