TeraWulf entered an 80-year lease for approximately 183 acres in Lansing, New York, to host high-performance computing (HPC) data center operations. The company prepaid rent with $95 million in common stock (valued using a 15-day trailing VWAP) and $3 million in cash, and agreed to share certain operating costs tied to the property. The lease includes customary covenants and permits TW Tenant to acquire the Premises for $100 after the 50th anniversary, with the landlord able to compel the sale on the same terms.
The transaction was reviewed by a special independent committee and accompanied by a fairness opinion from CBRE Capital Advisors because the Cayuga Landlord Parent is owned by TeraWulf's Chief Executive Officer. TeraWulf also restructured internal leases at Lake Mariner/Brookings covering 162.7 acres and providing access to power and infrastructure for up to 750 MW, enabling allocation between bitcoin mining and HPC businesses. The filing also discloses registration rights requiring a Form S-3 shelf registration within 60 days, and includes investor communications and an upcoming investor call and presentation.
TeraWulf announced that its indirect subsidiary Akela Data LLC entered into two data center lease agreements with Fluidstack to occupy more than 200 MW of critical IT load at the Lake Mariner campus for high-performance computing operations.

To support the leases, Akela, Fluidstack and Google LLC executed recognition agreements under which Google will backstop certain Fluidstack lease obligations; on tenant payment default or insolvency, Google may pay the termination fee or assume the lease. In exchange, TeraWulf issued Google warrants to purchase 41,011,803 common shares at <$0.01> per share, pledged to lenders until the Google backstop is effective. Akela will pay a $30 million initial commission to CBRE and an additional ~<$20 million> if further capacity is leased by March 31, 2026.
