WULFHIGH SIGNALOPERATIONAL10-K

TeraWulf has fundamentally repositioned from a bitcoin mining company to a diversified digital infrastructure provider targeting AI and high-performance computing workloads.

This strategic pivot represents a major business model transformation, moving away from volatile cryptocurrency mining toward more stable enterprise and hyperscale customers with long-term contracts. The shift suggests management is capitalizing on AI infrastructure demand while reducing exposure to bitcoin price volatility, though execution risk remains significant given the scale of this operational overhaul.
