Management Commentary

“Despite the challenging macro backdrop, 2022 was a transformational year for TeraWulf and we made significant progress on our strategic plan to build the preeminent low-cost, zero-carbon bitcoin miner,” stated Paul Prager, Founder and Chief Executive Officer of TeraWulf. “We commenced mining in March 2022, completed the construction and commissioning of 110 MW of world-class mining facilities in NY and PA, restructured our debt, and raised the last amount of external capital needed to achieve 160 MW and 5.5 EH/s of sustainable, low-cost bitcoin mining capacity.”

Patrick Fleury, TeraWulf’s Chief Financial Officer stated, “We are pleased with the financial performance of our first full year as a public company. While steadfastly focused on completing construction of our two bitcoin facilities, we remained financially nimble and reached a number of crucial financial milestones to improve the company’s liquidity position and increase financial flexibility, with the goal of achieving positive free cash flow once we are fully ramped to 160 MW.”

“Looking ahead, we plan to leverage our low-cost infrastructure to expand our self-mining hash rate at our existing sites, while also evaluating potential consolidation opportunities that enable us to grow our mining capacity in a financially responsible manner,” added Kerri Langlais, Chief Strategy Officer of TeraWulf.

Production and Operations Update

As of February 28, 2023, the Company had a self-mining hash rate of 2.6 EH/s with a total of approximately 26,000 miners deployed, comprised of 18,000 operational miners at the Lake Mariner facility (13,000 self-miners and 5,000 hosted miners) and approximately 8,000 self-miners at the Nautilus facility.

TeraWulf is currently expanding mining operations at its wholly owned Lake Mariner facility in New York with the addition of Building 2, which is expected to increase the facility’s operational capacity from 60 MW currently to 110 MW in Q2 2023. The Company has the ability to expand mining capacity at Lake Mariner by an additional 80 MW, for a total of 190 MW, in the near term.

The Company expects its full share in phase one of the Nautilus facility – 50 MW and 1.9 EH/s – to also be online in Q2 2023. TeraWulf has the option to add an additional 50 MW of bitcoin mining capacity at the Nautilus facility, for a total of 100 MW, which TeraWulf plans to deploy in future phases.

Across its two sites, the Company expects to have a total operational capacity of 50,000 miners (5.5 EH/s) in Q2 2023, representing approximately 160 MW of net mining infrastructure.

Fourth Quarter and Calendar 2022 Financial Results

Revenue in the fourth quarter of 2022 increased 146% to $9.6 million compared to $3.9 million in the third quarter of 2022. The increase is attributable to the significant increase in mining operations at the Lake Mariner facility following the August 2022 energization of Building 1 (50 MW), bringing online capacity at Lake Mariner from 10 MW to 60 MW and the introduction of a profit share component to short-term hosting agreements. Lake Mariner commenced mining operations in March 2022 and revenue for the full year 2022 was $15.0 million.

Cost of revenue as a percentage of revenue decreased to 55% in the fourth quarter of 2022 compared to 134% in the third quarter of 2022 primarily driven by improved miner fleet efficiency, and the normalization of unusually high NYISO Zone A energy prices. Cost of revenue for the full year 2022 was $11.1 million or 74% as a percentage of revenue.

Cost of Operations in the fourth quarter of 2022 increased by 46% to $17.7 million compared to $12.1 million in the third quarter of 2022. The increase in Cost of Operations was primarily driven by higher depreciation expenses, and higher Selling, General and Administrative expenses associated with scaling mining operations at the Lake Mariner facility in the fourth quarter of 2022. Cost of Operations was $47.7 million for the full year 2022. The Company continues to execute on its previously announced efforts to reduce operating expenses, with the target of decreasing cash operating costs by 25% over time.
