CORE SCIENTIFIC 2026 PROXY STATEMENT Letter to Stockholders

LETTER TO STOCKHOLDERS

During 2025, Core Scientific made meaningful progress in its transition toward high-density colocation infrastructure. The year was defined by execution: taking a large, contracted opportunity, expanding it, and translating it into physical development across multiple sites.

Early in 2025, we expanded our agreement with CoreWeave by an additional 70 megawatts, bringing total contracted capacity to approximately 590 megawatts across five data center sites and increasing projected revenue over the 12-year term to more than $10 billion. This agreement gives us scale, visibility, and a long-term framework for growth.

With this contracted capacity in place, a major focus in 2025 was execution and the delivery of the power and infrastructure required to support large-scale artificial intelligence and high-performance computing deployments by advancing projects in: Denton, Texas; Marble, North Carolina; Muskogee, Oklahoma; and Dalton, Georgia. This included solving for power, construction sequencing, equipment delivery, and operational coordination at a level of complexity that few companies have managed at comparable speed.

The scale of that effort was substantial. Across four locations, we advanced development of more than 1 million square feet of data center shell, installed nearly $2 billion of infrastructure assets, and supported more than 5 million labor hours, with an average of approximately 3,300 workers on site. In total, these buildouts represent more than $5 billion of infrastructure investment, the substantial majority of which is expected to be funded by our customer.

These figures are important because they reflect tangible progress towards building out the next generation of AI infrastructure. As of the date of this Proxy Statement, we had energized approximately 350 megawatts across these sites, with more than 180 megawatts online and billing. The work of building is now beginning to show up in the economics of the business.

2025 unfolded against a market backdrop, where at times, there were questions on the durability of AI demand. Our view remains that this industry is still in its early innings. The more important question for us is not whether demand would fluctuate quarter to quarter, but whether we are building the right assets in the right locations with the discipline required to serve long-duration customer needs.

The year also strengthened our position beyond existing contracts. As we advanced contracted capacity, we also continued to create a broader runway for growth: delivery of 2026 capacity tied to existing commitments, development pathways across multiple locations that are not yet under contract, and a larger opportunity set for future customers seeking ready, scalable infrastructure. Value in this sector comes not only from current deployments, but from controlling sites, ordering long-lead equipment, and moving projects through earlypre-construction work before demand fully crystallizes.

That is how we are deploying capital: with a practical focus on projects we believe offer the most attractive long-term returns, including site acquisitions, long-lead equipment orders, and early-stage development work that can accelerate future delivery.

We believe 2026 will mark an important inflection point for Core Scientific. 2025 was the year of building and energizing capacity, and we believe 2026 will be the year in which that effort becomes increasingly visible in revenue, operating profile, and new customer opportunities. We are entering the year with stronger infrastructure, deeper execution experience, and a broader strategic footing than we had a year ago.

Thank you for your continued support.
