Core Scientific Announces September 2024 Production and Operations Updates

Earned 345 Self-Mined Bitcoin in September for a Total of 5,621 Bitcoin Year-to-Date and 1,115 in the Third Quarter; Clients Earned an Estimated 66 Bitcoin at Our Data Centers in September

AUSTIN, Texas, September 7, 2024– Core Scientific, Inc. (Nasdaq: CORZ) ("Core Scientific" or “the Company”), a leader in digital infrastructure for bitcoin mining and high-performance computing,today released unaudited production and operations updates for September 2024.

"Our outstanding team continues to advance our customer-funded project to modify certain of our data centers to deliver nearly 400 megawatts of digital infrastructure for high-performance computing,” said Adam Sullivan, Core Scientific’s Chief Executive Officer. “In September, we completed the migration of all ASIC miners from two of our bitcoin mining data centers designated for HPC conversion. Our team is now diligently removing the associated cabling, power distribution units, racks and other mining infrastructure to facilitate this transformation.”

“Supporting our HPC expansion, we have commenced work on the sub-station at our Muskogee, OK site, where we plan to construct a state-of-the-art, 100-megawatt data center. Additionally, we are on schedule to finalize the 100-megawatt expansion of our Pecos, TX bitcoin mining data center. We remain committed to delivering powered infrastructure equipped with advanced liquid cooling systems, specifically optimized for AI GPU cloud workloads, for our HPC customer beginning in the first half of 2025. As we execute on our current projects, we are also focused on expanding our infrastructure portfolio to drive long-term growth and enhance shareholder value,” added Mr. Sullivan.

Data Centers

As of month-end, the Company operated approximately 198,000 bitcoin miners for both self-mining and hosting in our data centers, representing a total energized hash rate of 23.4 EH/s.

Digital Asset Self-Mining

Core Scientific earned 345 bitcoin in September from its owned fleet of miners. As of month end, the Company operated approximately 175,000 owned bitcoin miners, representing approximately 89% of the bitcoin miners operating in its data centers and a total energized hash rate of 20.4 EH/s.

Hosting Services for Bitcoin Mining

In addition to its self-mining fleet, Core Scientific provided data center hosting services, technology and operating support for approximately 22,000 hosted, customer-owned bitcoin miners, representing approximately 11% of the bitcoin miners operating in the Company’s data centers as of September 30, 2024. Customer-owned bitcoin miners earned an estimated 66 bitcoin in September, including bitcoin rewards paid to the Company pursuant to proceeds sharing agreements.

Grid Support

The Company reduced the consumption of power at its data centers on multiple occasions, delivering 45,262 megawatt hours to local electrical grids. The most frequent causes of power consumption reductions in September related to economic curtailments, over-temperature events and load response.
