Financing structure and lender participation

Morgan Stanley, which has led TeraWulf's previous bond offerings, will spearhead the upcoming debt transaction. CFO Fleury noted that many lenders who participated in TeraWulf's $250 million revolving credit line earlier this year could also participate in the Justified Data financing

The mixed financing approach combining leveraged loans and high-yield bonds suggests TeraWulf is diversifying its funding sources while tapping into strong investor appetite for AI infrastructure projects. As AI companies race to secure computing capacity for their models, data center operators with proven power infrastructure and development capabilities are positioned to benefit from multi-billion dollar commitments that extend decades into the future.
