TeraWulf Amends $250 Million Credit Facility, Removes Letter-of-Credit Sublimit
Key Facts
TeraWulf amended its revolving credit facility and removed the sublimit for letters of credit, according to a filing the company submitted to the U.S. Securities and Exchange Commission on October 23, 2026. Total commitments under the existing facility are $250 million, following its execution by the company on May 7, 2026. The amendment allows for the facility to be increased by about $150 million, but that is subject to commitments from additional lenders and the satisfaction of other conditions. This provision does not mean the facility has already increased to $400 million; the filing describes a potential, uncommitted increase. The amendment follows the company's October 5 announcement that it intended to increase the facility to support data center campus development and financing needs tied to its energy partnerships.
The original facility included a $150 million sublimit for issuing letters of credit, a restriction removed by the new amendment. Those letters are significant in the company's arrangements with utilities: TeraWulf said it is seeking to raise additional secured debt to support its needs for them under long-term energy development partnerships. The amended agreement also provides for the release of certain collateral from the agent's lien when specified conditions are met. Morgan Stanley Senior Funding serves as administrative agent and collateral agent, according to the filing. The amendment therefore changes the terms of the existing facility while providing a path to increase its size; it does not announce completed additional financing.
The amount available for use remains subject to the original agreement's provisions. The company's report for the quarter ended June 30, 2026, said that total borrowings and outstanding letters of credit may not exceed $75 million before the initial operating date. Total commitments under the facility are $250 million, but that figure does not mean the full amount can be drawn immediately at every stage. Under its original terms, the facility matures on May 7, 2030. Its maturity may be brought forward by 91 days from the maturity of the company's 2030 convertible notes if the conditions specified in the agreement are met. This places the financing within a long-term contractual framework, with restrictions tied to the operating phase and other debt maturities.
The company linked its financing needs to data center development as it moves to expand the electrical infrastructure at its Musky campus in eastern Kentucky. TeraWulf increased the campus's contracted power capacity from 500 megawatts to 1 gigawatt, according to a statement attached to its filing. Its chief executive said, "Power availability is central to those discussions," referring to talks with prospective customers about the site. The company continues to assess whether Musky could support up to 2 gigawatts of capacity over time, but that depends on further utility and infrastructure planning and agreements. This power expansion connects the need for letters of credit and energy partnerships, on one hand, with plans to develop data center capacity on the other.
The amendment coincides with an operational shift that the company said centers on leasing high-performance computing capacity as its primary growth driver, while reducing and repurposing part of the infrastructure previously used for bitcoin mining. TeraWulf said high-performance computing leasing accounted for a majority of its revenue in the three and six months ended June 30, 2026. In the first quarter of the same year, revenue was $34 million, including $21 million from high-performance computing leasing. These figures provide context for the company's strategy of developing data center campuses, while the latest filing identifies power needs and letters of credit as financing drivers. The filing does not say the facility increase is intended to fund cryptocurrency mining activities.
Second-quarter data show that cash and cash equivalents totaled $2.6192 billion on June 30, 2026, compared with $3.2664 billion on December 31, 2025. While the revolving facility provides an existing credit framework, the potential optional increase requires additional lender commitments, and the filing does not guarantee it will be obtained. The company also said the facility increase is subject to customary closing conditions and that it "cannot guarantee that any additional financing will be obtained." TeraWulf is expected to attach the full text of the amended credit agreement to its quarterly report for the quarter ended September 30, 2026. That will provide access to the amendment's detailed contractual terms, while the size of any actual increase remains contingent on satisfying the conditions and securing lenders.
