Expansion of existing loan facility, further solidifying partnership with lenders.

Initial delivery of latest generation S19 XP miners expected to be operational in August 2022.

TeraWulf Inc. (Nasdaq: WULF) (“TeraWulf” or the “Company”), which owns and operates fully integrated, domestic bitcoin mining facilities powered by more than 91% zero-carbon energy, announced it has entered into a first amendment to the Loan Agreement with its existing lender group for an additional $50 million of debt. The Company intends to use net proceeds towards completing the datacenter infrastructure at its Lake Mariner facility in New York and Nautilus Cryptomine facility in Pennsylvania.

In addition, the Company announced that it anticipates its initial batch of 3,000 S19 XP mining machines from the previously announced purchase agreements with Bitmain Technologies Limited (“Bitmain”) for its Lake Mariner Facility in New York will be operational in August. After the initial batch, the Company has approximately $60 million in deposits under the purchase agreements, which will be applied to additional monthly batches based on the then current prices for miners.

Irene Gao, Antminer Sales Director of NCSA Region, Bitmain, commented, “Delivery of the initial batch of S19 XPs – currently the most efficient bitcoin miner in the market – marks a key milestone for TeraWulf as they begin rapidly scaling their self-mining operations. The high-performance and low power consumption of the S19 XP miners should significantly benefit TeraWulf’s sustainable and low-cost mining business. We are confident in the Company’s vertically integrated business model as we continue to expand our long-term partnership with TeraWulf.”

TeraWulf announced it is commencing the third quarter with approximately 3,300 miners online at its Lake Mariner facility and expects to significantly ramp operations monthly with the completion of the data center infrastructure at its Lake Mariner and Nautilus Cryptomine facilities.

“Our ability to secure this new capital, together with the near-term deployment of the S19 XP miners at Lake Mariner, is further indication of TeraWulf's continued momentum,” said Paul Prager, Chief Executive Officer and chair of the board of TeraWulf. “We expect the third quarter to be transformational for the Company as we successfully shift from major construction activities at our sites to an operational mining company with a significant ramp in hash rate.”

Mr. Prager continued, “TeraWulf’s accomplished executive team is time-tested and has been through its share of difficult market cycles. Our current priority is to ensure that we are resilient and securely positioned to not only operate and scale the business, but also take advantage of certain value-creating opportunities that might otherwise not be available during more healthy markets. It is during the present challenging market backdrop that our long-standing relationship with Bitmain and access to additional funding has enabled us to opportunistically translate our capital into deliveries of the latest generation equipment at historically low market prices, while also expecting to benefit from an increased share of the global network hashrate.”

TeraWulf previously announced that it is in the final stages of completing its first dedicated mining building at Lake Mariner, which will house approximately 50 MW of capacity. The Nautilus Cryptomine facility, a partnership between TeraWulf and Talen Energy Corporation, has also made significant construction progress and remains on target to begin mining in the third quarter.
