TeraWulf Announces Fluidstack Expansion with 160 MW CB-5 Lease at Lake Mariner

Total Contracted Capacity Increases to Over 360 MW of Critical IT Load

Represents $6.7 Billion in Contracted Revenue, with Potential to Reach $16 Billion with Lease Extensions

Google Increases Backstop to $3.2 Billion and Stake in TeraWulf to 14%

TeraWulf and Fluidstack Engaged in Discussions Regarding Additional Capacity

EASTON, Md., Aug. 18, 2025 (GLOBE NEWSWIRE) -- TeraWulf Inc. (Nasdaq: WULF) (“TeraWulf” or the “Company”), a leading owner and operator of vertically integrated, predominantly zero-carbon digital infrastructure, today announced that Fluidstack, a premier AI cloud platform, has exercised its option to expand at the Company’s Lake Mariner data center campus in Western New York. The expansion adds CB-5, a new purpose-built data center building providing an incremental 160 MW of critical IT load, with operations expected to commence in the second half of 2026.

In connection with the new CB-5 lease, Google will provide an incremental backstop of $1.4 billion in support of project-related debt financing and will receive warrants to acquire 32.5 million shares of TeraWulf common stock. With this incremental commitment, Google’s total backstop increases to approximately $3.2 billion, and its total pro forma equity ownership in TeraWulf increases to approximately 14%.

The CB-5 lease is on the same economic terms as the initial Fluidstack leases for CB-3 and CB-4, maintaining consistency in structure and economics across the buildout.

Strategic Expansion at Lake Mariner

The CB-5 expansion builds on the previously announced agreements under which TeraWulf is delivering more than 200 MW of AI-optimized data center capacity to Fluidstack at Lake Mariner. With CB-5, total contracted critical IT load for Fluidstack at the campus increases to approximately 360 MW, reinforcing Lake Mariner’s position as one of the largest high-performance computing (HPC) campuses in the U.S. TeraWulf and Fluidstack are also engaged in ongoing discussions regarding additional capacity expansions.

Leadership Commentary

“This expansion underscores the unmatched scale and capabilities of the Lake Mariner campus,” said Paul Prager, Chief Executive Officer of TeraWulf. “By adding CB-5, we are not only increasing our contracted capacity with Fluidstack, but also further deepening our strategic alignment with Google as a critical financial partner in delivering the next generation of AI infrastructure.”

“This expansion not only scales our contracted platform but reinforces TeraWulf’s leadership in the AI and HPC infrastructure ecosystem, delivering globally competitive, sustainable, and scalable compute solutions,” added Prager.

“Fluidstack’s decision to expand so soon after our initial agreement speaks volumes about the quality, readiness, and scalability of our infrastructure,” said Nazar Khan, Chief Technology Officer of TeraWulf. “Like the prior buildings, CB-5 will be purpose-built for high-density, liquid-cooled workloads, leveraging Lake Mariner’s dual 345 kV transmission lines, sustainable water cooling, and ultra-low-latency connectivity. And with the scale, resources, and infrastructure we have in place, there is significant potential for even further expansion with Fluidstack as their compute requirements continue to grow.”
