Management Comments

• "The third quarter into the fourth has been remarkably busy for TeraWulf. We expanded our partnership with Fluidstack and Google at Lake Mariner and extended that relationship into the Southwest Power Pool with the Abernathy joint venture. These transactions demonstrate the strength of our platform and the trust that world-class technology partners place in our ability to execute. Our portfolio of scalable, low-carbon sites provides a powerful foundation to continue expanding in both existing and new markets." Paul Prager, Chief Executive Officer.
• "We are squarely focused on execution while advancing the next phase of growth for 2027 and beyond. The Cayuga lease, the expansion optionality embedded in Abernathy, and our in-house pipeline, where several projects are approaching realization, all underscore the depth of our opportunity set and the durability of our long-term strategy." Paul Prager, Chief Executive Officer.
• "At Lake Mariner, execution remains our top priority. We delivered WULF Den and CB-1 in the third quarter, with CB-2 nearing completion. Construction at Akela continues to progress rapidly as we move through key HPC delivery milestones. Across the portfolio, our focus is on achieving efficient, de-risked execution for our tenants and building the reliability that defines our operating advantage." Sean Farrell, Chief Operating Officer.
• "Over the past several months, we have completed more than $5 billion in capital formation, underscoring investor confidence in our business model and growth trajectory. The success of our recent secured note offering provides a blueprint for how we intend to fund and scale our platform going forward. We remain committed to disciplined capital allocation and creating long-term value for our shareholders." Patrick Fleury, Chief Financial Officer.

Industry Context

TeraWulf's strategic shift and rapid expansion into high-performance computing (HPC) infrastructure, particularly for AI workloads, aligns with the booming demand for compute capacity driven by advancements in artificial intelligence. Its focus on low-carbon energy and vertically integrated operations positions it favorably in an industry increasingly scrutinized for its environmental impact. Partnering with hyperscale players like Google (via Fluidstack) and G42 (via Core42) demonstrates its ability to attract top-tier customers, a critical differentiator in the competitive data center market. This move diversifies its revenue streams beyond volatile Bitcoin mining, offering more stable, infrastructure-style cash flows, which is a significant trend in the digital infrastructure sector.

Comparison to Industry Standards

• The company's partnerships with Fluidstack (backed by Google) and Core42 (backed by G42) indicate a strong alignment with hyperscale and enterprise customer standards for HPC infrastructure.
• The Google credit enhancement on Fluidstack leases (totaling $4.5 billion across all leases) provides a significant de-risking factor, comparable to investment-grade credit support seen in other large-scale infrastructure projects.
• The "BB" rating from leading agencies (Moody's, S&P, and Fitch) for the $3.2 billion Senior Secured Green Notes due 2030, recognizing Google's support and collateral, positions TeraWulf within institutional credit markets, establishing a benchmark for robust financing structures.
• The target Power Usage Effectiveness (PUE) of < 1.25 and utilization of low-carbon grid power for its "Eligible Green Project" financing aligns with leading sustainability benchmarks in the data center industry.
• The average annual NOI margin of approximately 85% for Lake Mariner HPC leases (Core42 and Fluidstack) suggests strong operational efficiency and profitability potential, which is competitive within the colocation and data center sector.

Related Party Transactions

• Operating expenses related party: $1.582 million in Q3 2025 ($856 thousand in Q3 2024).
• Selling, general and administrative expenses related party: $126 thousand in Q3 2025 ($2.976 million in Q3 2024).
• Share based liability due to related party: $10.747 million as of September 30, 2025.
• Other amounts due to related parties: $145 thousand as of September 30, 2025 ($1.391 million as of December 31, 2024).
• Related party expense settled with respect to common stock: $2.375 million for the nine months ended September 30, 2025.

Stakeholder Impact

• Shareholders: Significant net loss in Q3 2025 will negatively impact reported earnings per share. However, the strategic shift to HPC, securing large contracts, and substantial financings could be viewed positively for long-term value creation and diversification. The increase in total liabilities and debt could be a concern.
• Customers (Fluidstack, Core42): The rapid buildout of HPC capacity and the company's focus on efficient, de-risked execution are beneficial for these key tenants.
• Creditors/Investors in Notes: The successful $5 billion in financings, particularly the Google credit enhancement on leases, provides a strong collateral package and de-risks the investments in the new notes. The "BB" rating validates the credit strength.
• Employees: Continued expansion and new project developments suggest job stability and potential growth opportunities.

Next Steps

• CB-2 HPC facility anticipated to come online around year-end 2025.
• Akela Data LLC construction to progress rapidly with capacity online in phases throughout 2026.
• Fluidstack leases at Lake Mariner to be delivered in phases through 2026.
• Abernathy JV to develop 240 MW of HPC capacity, with potential site expansion to 600 MW.
• Development of future phases at Abernathy leveraging existing transmission infrastructure.
• Development of a future approximately 200 MW Fluidstack-led project.
• Large-scale HPC deployment at Cayuga site beginning in 2027.
• Continue to build on in-house development pipeline with several projects approaching realization.
• Target 250-500 MW critical IT load of new HPC lease signings annually.
• Host earnings conference call and webcast on November 10, 2025, at 4:30 p.m. Eastern Time.

Recommendation

Despite a significant reported net loss primarily due to non-cash accounting adjustments related to warrant and derivative liabilities, the underlying operational and strategic performance of TeraWulf is exceptionally strong and transformative. The company has successfully pivoted towards high-growth HPC infrastructure, securing over $17 billion in long-term, credit-enhanced contracts with industry giants like Google (via Fluidstack) and G42 (via Core42). This shift provides stable, infrastructure-style cash flows, significantly de-risking the business model from the volatility of Bitcoin mining. The completion of over $5 billion in strategic financings, including a $3.2 billion Senior Secured Green Notes offering with an institutional-grade "BB" rating, demonstrates robust capital market access and investor confidence. The rapid expansion of HPC capacity, strong Adjusted EBITDA growth, and a clear pipeline for future development position TeraWulf as a leader in sustainable digital infrastructure. The current market may overreact to the headline net loss, creating a compelling entry point for long-term investors recognizing the fundamental strength and strategic execution.
