Do Rising Costs Raise a Red Flag Despite WULF's Revenue Growth?
Read MoreHide Full Article
Key Takeaways
WULF posted 37% revenue growth to $35.4 million, but rising costs compressed margins significantly.
Cost of revenues surged 46% year over year, outpacing revenue growth and reducing gross margin to 38%.
Net income margin declined to 15% from 21%, raising concerns about profitability amid volatility.
TeraWulf (WULF - Free Report) posted strong revenue growth in its third quarter of 2025, reaching $35.4 million compared to $25.8 million in the prior-year period, yet mounting operational expenses and compressed margins raise questions about the sustainability of its profitability trajectory. The bitcoin miner's 37% year-over-year revenue increase reflected expanded mining output, but the accompanying cost structure tells a more concerning story.
The company's cost of revenues surged to $21.8 million from $14.9 million year over year, driven primarily by higher power costs and increased depreciation expenses related to its expanded mining fleet. This 46% jump in costs outpaced revenue growth, compressing gross margins to 38% from 42% in the prior-year quarter. While TeraWulf has benefited from operational scale at its facilities, the rate of cost inflation appears troublingly persistent.
Operating expenses also escalated significantly, with total operating costs climbing to $30.1 million compared to $20.3 million in the year-ago period. General and administrative expenses rose to $8.3 million, while stock-based compensation added further pressure to the bottom line, diluting shareholder value as the company retains talent in a competitive sector.
The margin compression becomes particularly worrisome when considering bitcoin's price volatility and network difficulty adjustments. TeraWulf's net income of $5.3 million, while positive, represented a margin of just 15%, down from 21% in the previous year. The company's capital expenditure commitments for additional mining capacity could further strain cash flows if bitcoin prices soften or network competition intensifies, making cost management increasingly critical for maintaining profitability.
How Do Rivals Compare on Cost Management?
Riot Platforms (RIOT - Free Report) reported third-quarter 2025 revenues of $84.8 million with cost of revenues at $58.9 million, yielding a gross margin of approximately 31%. Riot Platforms' operating expenses totaled $47.2 million, resulting in an operating loss despite its larger revenue base. The company's cost structure reflects significant depreciation and power expenses across its multiple facilities. Meanwhile, Cipher Mining (CIFR - Free Report) generated $29.8 million in quarterly revenue with cost of revenues at $17.6 million, achieving a stronger gross margin of 41%. Cipher Mining's operating expenses came in at $15.4 million, demonstrating tighter cost control relative to its revenue scale. Cipher Mining's operational efficiency appears superior, though Riot Platforms maintains substantially larger mining capacity and infrastructure investments that position it differently for long-term market dynamics.
TeraWulf shares have appreciated 99.5% year to date, outperforming the broader Zacks Finance sector’s return of 11.1% and the Zacks Financial Miscellaneous Services industry’s decline of 11.2%.
