I want to express my gratitude to our team, especially our COO Scott Garrison and CTO Taylor Monnig, for their grit and leadership. Under their direction, the tireless efforts of our operations and technology teams resulted in the addition of over 10 EH/s of capacity across four states to achieve the ambitious target.

It's the result of building and operating our own infrastructure, often from the ground up, which has given us the control, resilience, and scalability needed to lead in this industry."
