$CORZ filed an amended annual report on March 18, 2026, covering the fiscal year ended December 31, 2025. The 10-K/A is the definitive source for the company's full-year operating picture: fleet scale, power contract structure, hosting customer demand, and the risk factors that frame how the business performs when Bitcoin prices move.

Core Scientific sits in Sawse's Bitcoin miner and hosting operator category. That framing matters because $CORZ generates revenue through two distinct channels. Self-mining ties results directly to Bitcoin price and network difficulty. Hosting revenue ties results to whether large-scale customers, typically other miners or high-performance compute operators, are filling contracted capacity. Both channels are sensitive to Bitcoin economics, but they respond differently to the same price environment. A Bitcoin rally lifts self-mining margins immediately. Hosting revenue is stickier but depends on contract fill rates and customer creditworthiness.

Revenue Scale and the Hosting Mix

The latest loaded revenue figure for $CORZ is $115.24 million for the period ending March 31, 2026. That number is a quarterly snapshot, not the full fiscal 2025 annual figure, but it establishes the current run rate as the 10-K/A disclosure is being absorbed by the market. The annual filing itself is the source for full-year revenue composition, and the hosting-versus-self-mining split is the number that tells investors how much of the top line is locked into contracted capacity versus floating with Bitcoin price.

For a company with an 80 BTC Exposure Score, that split carries real weight. The direct balance-sheet and revenue sensitivity to Bitcoin means that any change in the hosting mix, whether $CORZ is adding high-performance compute contracts or leaning harder into self-mining, reshapes the earnings profile in ways that quarterly snapshots alone do not capture.

What the Amended Filing Signals

The 10-K/A designation means $CORZ filed an amendment to its original annual report. Amendments can address a range of items: restated financials, corrected exhibits, updated certifications, or additional disclosures required after the original filing date. The specific amendment scope is in the filing itself at the SEC primary document. What the amendment does not automatically signal is financial distress or a material restatement. The elevated Filing Risk Score reflects the disclosure pattern intensity that comes with an amended annual filing, not a judgment about company quality.

That distinction matters for reading the score correctly. $CORZ's Filing Risk Score at 100 means the disclosure cadence around this filing requires close attention. An amended 10-K for a Bitcoin miner with a large hosting operation is a document worth reading in full, because changes to risk factors, power contract disclosures, or segment reporting can shift the operating picture in ways that the original filing did not capture.

The Risk Factor Layer

For Bitcoin miners and hosting operators, the risk factor section of an annual filing is where the real operating constraints live. Power contract terms, regulatory exposure in specific jurisdictions, customer concentration in the hosting book, and network difficulty assumptions all show up in risk factors before they show up in revenue. $CORZ's 10-K/A risk factor section is the place to look for any new language around power costs, hosting customer defaults, or changes in the competitive landscape for large-scale compute capacity.

The crypto Fear and Greed index sat at 28, classified as fear, at the time of this analysis. Bitcoin dominance was 58.1%, indicating a Bitcoin-led tape rather than a broad altcoin rotation. For a miner with $CORZ's direct Bitcoin sensitivity, a fear-regime environment with Bitcoin holding dominance is a specific operating context: self-mining margins are under pressure from sentiment, but the Bitcoin network itself remains the dominant asset in the crypto market. That context frames how the 10-K/A risk factors read today versus how they would read in a greed-regime environment.

Price Performance Against the Filing Backdrop

$CORZ has gained approximately 112% over the trailing year through May 20, 2026, and is up roughly 59% year to date over the same period. The stock set a 52-week high of $25.17 on May 14, 2026, just days before this analysis. Both short-term and long-term trend classifications are uptrend. The stock is trading above its 20-day, 50-day, and 200-day moving averages.

That price context does not change what the 10-K/A says, but it sets the stakes for what the filing reveals. A stock near a 52-week high with a ceiling-level disclosure intensity score is a combination that rewards careful reading of the amendment. If the amended filing introduces new risk language or changes segment disclosures in ways that complicate the operating narrative, the price context makes that more consequential than it would be at a 52-week low.

The Insider Activity Signal for $CORZ sits at 44, below the neutral 50 baseline. The Form 4 tape is not generating unusual cluster activity at this point. That is a separate read from the filing itself, but it means the insider signal is not amplifying the disclosure story in either direction.

The Hosting Model Is the Durable Question

Self-mining economics get most of the attention in Bitcoin miner coverage because they are the most direct Bitcoin price proxy. But for $CORZ, the hosting and high-performance compute side of the business is where the longer-term operating durability question lives. Power contracts are multi-year commitments. Customer relationships in the hosting book are stickier than spot mining economics. If the 10-K/A shows $CORZ expanding contracted capacity or diversifying its hosting customer base beyond pure Bitcoin miners into AI or HPC workloads, that changes the revenue sensitivity profile in ways that the BTC Exposure Score alone does not fully capture.

The annual filing is the document that answers that question with specificity. Quarterly filings show the revenue line. The 10-K/A shows the contract structure, the customer concentration, and the power cost assumptions that sit underneath it.
