TeraWulf reported full-year 2025 total revenue of $168.5 million, a 20.3% increase from the prior year, yet its net loss widened to a staggering $661.4 million compared to $72.4 million in 2024. The Nasdaq-listed bitcoin miner is pivoting aggressively toward high-performance computing (HPC) infrastructure, with the transition costs now fully visible in its books.
HPC Leasing Starts Small but Mining Income Shrinks Fast
Newly launched HPC leasing operations contributed $16.9 million in annual revenue, signaling early financial traction for its AI-focused pivot. Management described 2025 as a year of structural repositioning: the company secured long-term data center lease agreements covering 522 megawatts of critical IT load, representing over $12.8 billion in contracted customer revenue, backed by $6.5 billion in financing for HPC buildout.
However, legacy mining revenue suffered a sharp decline. Fourth-quarter digital asset revenue dropped to $26.1 million from $43.4 million in Q3, due to lower bitcoin production and softer market pricing. HPC lease revenue rose to $9.7 million in Q4 from $7.2 million in Q3, partially offsetting mining weakness and shifting the revenue mix toward more predictable infrastructure contracts.
What Drove the $661M Loss
The massive net loss stems largely from heavy capital expenditures and accounting impacts related to scaling next-generation data centers. Non-GAAP adjusted EBITDA came in at -$23.1 million, highlighting the near-term financial strain of infrastructure-heavy investment. CEO Paul Prager noted that TeraWulf entered 2026 with 522 MW of contracted HPC capacity and a gross 2.9 GW multi-regional platform. Earlier this month, the company acquired brownfield sites in Kentucky and Maryland, adding about 1.5 GW of capacity to further bet on the AI-driven data center market.
Investors now face a mixed picture: revenue growth and HPC momentum on one side, a widening loss that underscores the heavy cost of transformation on the other.
