Management Commentary

"During the month of September, the Company mined 329 bitcoin, consistent with August's bitcoin production despite unfavorable network factors including a 2.7% increase in network difficulty month over month," said Sean Farrell, SVP of Operations at TeraWulf. "We are committed to being a responsible load resource, and while operating performance was optimized at the Lake Mariner and Nautilus facilities during the month due to enhanced miner repairs, these efficiency benefits were offset by facility downtime at Lake Mariner due to demand response activity earlier in the month," added Farrell.

"The third quarter of 2023 was monumental for TeraWulf as it represents the first full quarter of 5.5 EH/s of operational capacity across our portfolio. Correspondingly, the Company generated meaningful free cash flow during the quarter, which will be applied to reduce indebtedness," said Patrick Fleury, Chief Financial Officer of TeraWulf. "Our operating and financial goals remain clear: maximize profitability, reduce debt, execute on accretive organic and external growth opportunities, and return value to our shareholders," continued Fleury.

Production and Operations Update

As of September 30, 2023, the Company had an operational miner fleet of approximately 50,000 of the latest generation miners, comprised of 34,000 miners at its wholly owned Lake Mariner facility in New York (5,000 of which are hosted pursuant to an agreement expiring in the fourth quarter of 2023) and 16,000 self-miners at the nuclear-powered Nautilus facility in Pennsylvania.

The previously announced 43 MW expansion at Lake Mariner is progressing and remains on target for completion by year-end 2023.

⁴ While nameplate inventory for WULF's two facilities is 5.5 EH/s, inclusive of gross total hosted miners, actual monthly hash rate performance depends on a variety of factors, including (but not limited to) performance tuning to increase efficiency and maximize margin, scheduled outages (scopes to improve reliability or performance), unscheduled outages, curtailment due to participation in various cash generating demand response programs, derate of ASICS due to adverse weather and ASIC maintenance and repair.
