TeraWulf
WULF shares have appreciated 90.1% year to date (YTD), underperforming the Zacks Financial- Miscellaneous Services industry and the Zacks Finance sector’s return of 5.2% and 13.4%, respectively. This vertically integrated owner and operator of next-generation digital infrastructure, purpose-built to support bitcoin mining and high-performance computing (HPC) workloads, reported revenues of $47.6 million, up 38% sequentially and 34% year over year in the second quarter of 2025.
WULF self-mined 485 bitcoin at the Lake Mariner facility in the second quarter of 2025, and bitcoin mining capacity jumped 45.5% year over year to 12.8 EH/s. As of June 30, 2025, TeraWulf owned approximately 70,300 miners, with approximately 65,100 operational at the facility. However, power cost per bitcoin self-mined jumped 98.5% year over year due to halving (in April), rising network difficulty and short-term power price volatility. Adjusted EBITDA was $14.5 million, down 25.6% year over year in the second quarter of 2025 against a negative $4.7 million in the first quarter of 2025.
However, TeraWulf expects power prices in Upstate New York to remain steady with historical levels for the rest of 2025. The company now expects 5 cents per kilowatt hour for the second half of the year and mining operations to contribute positively to EBITDA. However, WULF expects selling, general and administrative expenses between $50 million and $55 million compared with previous guidance of $40-$45 million due to accelerated growth in the company’s HPC business.
So, how should investors play WULF stock now? Let’s analyze.
