Core Scientific (CORZ) Q1 2026 earnings review
Colocation Pivot Accelerates, But the Cost of Abandoning Crypto is Steep
Core Scientific's Q1 2026 results confirm a radical and accelerating transformation. Total revenue grew 45% YoY to $115.2M, driven entirely by a massive surge in Colocation revenue ($77.5M, up from $8.6M a year ago). However, this pivot comes at a heavy price: the legacy Bitcoin self-mining business is in absolute freefall, posting a devastating -57% gross margin and triggering a massive $266.5M non-cash impairment charge on equipment. Adjusted EBITDA reversed to positive $4.4M (from -$6.1M YoY), reflecting the superior economics of the CoreWeave contract. Management is aggressively front-loading a $2 billion CapEx plan for 2026 to build out a 3.0 GW pipeline, relying heavily on a new $3.3B debt raise. While execution on the physical build is impressive, the glaring failure to sign a second major customer beyond CoreWeave remains the anchor on the bull thesis.
🐂 Bull Case
The high-density colocation (HDC) segment hit a 57% gross margin in Q1, generating $43.9M in gross profit. This validates management's claim that AI infrastructure yields far superior unit economics compared to crypto mining.
The successful $3.3B 7.75% senior secured notes offering fully funds the immediate infrastructure pipeline. Core Scientific now has $1.04B in liquidity and is actively building ahead of contracts ('Operation Forward Observer') to win deals on speed-to-market.
🐻 Bear Case
Self-mining gross profit was a negative $17.1M (-57% margin). The company took a $266.5M impairment charge to clear out obsolete PP&E. This segment is bleeding cash and dragging down consolidated metrics.
The company has yet to announce a new major tenant beyond CoreWeave. With $2B in guided CapEx for 2026 and 243 MW currently billing, building massive capacity on spec without a diversified anchor tenant introduces extreme balance sheet risk.
⚖️ Verdict: ⚪
Neutral. The operational pivot is a masterclass in execution—energizing megawatts at an unprecedented pace. However, the failure to diversify the customer base beyond CoreWeave, combined with the heavy cash burn of the dying Bitcoin business and a $2B CapEx plan, makes the risk/reward profile highly speculative until a second anchor tenant is signed.
Key Themes
CoreWeave Ramp Drives Dramatic Margin Expansion
The colocation segment is officially the engine of the company. In 26Q1, colocation revenue reached $77.5M with a 57% gross margin, up from 5% a year ago. The company is now billing for 243 MW of capacity, representing ~$350M in average annualized revenue. The transition from capital-intensive, volatile mining to high-margin, predictable take-or-pay colocation contracts is working as modeled.
The Brutal End of Self-Mining
Management's previous assertion that Bitcoin mining is 'in runoff' was an understatement. In Q1, the segment produced a negative 57% gross margin (cost of revenue was $47.2M against $30.1M in revenue). Furthermore, the company swallowed a $266.5M impairment charge on PP&E and a $13.6M loss on disposal. This business is now a severe liability that must be disconnected as quickly as colocation conversions will allow.
Customer Concentration & Empty 'Exclusivity' Claims
Despite heavily promoting a '1.5 GW leasable customer power pipeline' and explicitly promising new hyperscale or neocloud customers in prior quarters, Core Scientific still has not announced a second major tenant. The Q1 presentation notes that the '$2B 2026 CapEx plan assumes no new customer contract.' Building out Hunt County (430 MW) and Polaris (440 MW) without signed, investment-grade guarantees is a dangerous game of 'build it and they will come.'
Capital Readiness and Supply Chain Dominance
The company's 'Operation Forward Observer' strategy—investing ahead of contracts to secure long-lead equipment and advance ready-for-service dates—is in full swing. CapEx hit a record $389.2M in Q1. The recent $3.3B note offering clears the runway to aggressively fund this strategy. If demand materializes, Core Scientific will be the only operator with physical, energized megawatts ready for immediate deployment.
Behind-the-Meter (BTM) Power Strategy
To bypass congested utility interconnection queues, Core Scientific is pivoting toward Behind-the-Meter solutions. Management identified ~900 MW of BTM expansion opportunity. By utilizing natural gas and favorable air permit areas, they aim to bring power online in ~24 months, significantly faster than traditional grid interconnection timelines.
Other KPIs
Reversing from $(6.1) million in Q1 2025. The transition is finally producing positive operating cash flow proxies, driven by a $35.7 million increase in total revenue. However, it was partially offset by a $17.5 million increase in cash cost of revenue and an $11.9 million increase in adjusted operating expenses, reflecting the heavy overhead required for the colocation pivot.
Consists of $1.01B in cash and $37.3M in Bitcoin. This is up substantially from the end of FY25, heavily fortified by the new debt issuance. The balance sheet is loaded, but it needs to be—management plans to deploy ~$2B in CapEx throughout 2026.
The company continues to suffer non-cash losses below the operating line due to changes in the fair value of warrants and contingent value rights. Current warrant liabilities sit at an astonishing $844.7M. While non-cash, this severely dilutes the GAAP net income picture and creates massive quarter-to-quarter earnings volatility.
Guidance
Accelerating dramatically from $729M in FY25. This assumes no new customer contracts and is purely focused on readying the 1.5GW pipeline. It implies an average quarterly cash burn of $500M, meaning the current $1B cash pile and $3.3B debt raise will be aggressively deployed.
Management expanded its pipeline outlook. This consists of ~520MW existing, ~285MW Hunt County, ~330MW Muskogee, ~370MW unannounced, ~900MW Behind-the-Meter, and ~600MW currently in load study. Execution on this metric is the sole determinant of the company's terminal value.
This is the stabilized run-rate expected purely from the CoreWeave contract (590 MW total) once fully delivered. Given they are currently billing for 243 MW at a ~$350M run rate, this implies an additional $500M in annualized revenue will come online over the next 12-18 months.
Key Questions
Customer Diversification Timeline
You are guiding to $2B in CapEx this year without a signed contract beyond CoreWeave. At what point does 'Operation Forward Observer' become speculative overbuilding if the anticipated hyperscale/neocloud contracts continue to be delayed by investment-grade guarantee negotiations?
Self-Mining Sunset Strategy
Self-mining posted a -57% gross margin this quarter. Are there contractual minimum power obligations preventing you from immediately pulling the plug on the remaining fleet, and how much cash will this segment burn before it is fully decommissioned?
Behind-the-Meter Execution Risks
You highlighted a 900 MW Behind-the-Meter opportunity using natural gas. Given the regulatory complexities and environmental permitting involved in onsite generation, what is your realistic timeline and capital outlay for these specific MWs compared to grid-connected projects?
