Core Scientific Announces January 2024 Production and Operations Updates

• Operated approximately 218,000 owned and hosted bitcoin miners
• Produced 1,027 self-mined bitcoin and an estimated 354 bitcoin from hosted miners in January
• Expanded self-mining energized hash rate by 1.7 EH/s with new miner deployments
• Improved self-mining fleet energy efficiency by five percent, to 26.44 Joules per Terahash (J/TH)

Core Scientific, Inc. (Nasdaq: CORZ, CORZW, CORZZ) ("Core Scientific" or “the Company”), a leader in bitcoin mining and infrastructure for high-value compute, today released production and operations updates for January 2024.

“Core Scientific produced 13,762 bitcoin in 2023, more than any other listed company in North America and providing strong momentum as we entered into 2024,” said Adam Sullivan, Core Scientific’s Chief Executive Officer. “In January we relisted on Nasdaq with a strengthened balance sheet, a pathway to reduce leverage further and a pragmatic growth plan for an additional 72 megawatts of infrastructure at our existing Texas sites this year.”

“Our ongoing deployment of new, more efficient miners in January not only increased our energized hash rate, but also improved our fleet efficiency. Along with multiple additional initiatives well underway, we believe improving our fleet efficiency helps to position us more favorably for the upcoming halving,” Mr. Sullivan added.

Key Metrics Summary

Data Centers

As of month-end, the Company operated approximately 218,000 bitcoin miners for both self-mining and hosting, representing a total energized hash rate of 24.8 EH/s at its data centers in Georgia, Kentucky, North Carolina, North Dakota and Texas.

Self-Mining

Core Scientific produced 1,027 bitcoin in January from its owned fleet of miners. As of month end, the Company operated approximately 167,000 owned bitcoin miners, accounting for approximately 77% of its total number of miners and representing a total energized hash rate of 18.6 EH/s.

Hosting Services

In addition to its self-mining fleet, Core Scientific provided data center hosting services, technology and operating support for approximately 51,000 hosted, customer-owned bitcoin miners, representing approximately 23% of the bitcoin miners operating in the Company’s data centers as of January 31. Customer-owned bitcoin miners produced approximately 354 bitcoin in January, 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 several occasions in January, delivering 18,487 megawatt hours to local grid partners. By supporting the grid in such a fashion, Core Scientific helps grid operators keep power flowing to their customers when temperatures rise and air conditioning use increases, and when temperatures drop and heating use increases. Core Scientific works with utility companies and the communities in which it operates to enhance electrical grid stability.

New Miner Deployments

The Company completed the deployment of 28,400 new Bitmain S19j XP miners procured from Bitmain under a contract announced on September 21, 2023. The new miners are rated to operate at between 141 and 151 Terahash (“TH”) and an average of approximately 22 J/TH, increasing energized hash rate while also helping to improve the efficiency of the Company’s self-mining fleet. Core Scientific expects to deploy an additional 12,600 Bitmain S21 miners by the end of July 2024, representing 2.5 EH/s in energized hash rate and operating at 17.5 J/TH.
