It operated about 209,100 miners and reported 27.94 joules per terahash average self-mining fleet efficiency. Contracted power capacity was approximately 1,198 MW; average hourly operating power demand during 2023 was approximately 592 MW.
Changes versus the prior comparable period
- Revenue fell 22% to $502.4 million. Self-mining revenue declined 2% to $390.3 million, as increased Bitcoin network difficulty largely offset higher self-mining hash rate and a 2% increase in average bitcoin price.
- Hosting revenue declined, and the company ended equipment sales. Hosting revenue was affected by terminated customer contracts, including contracts the company said were less profitable.
- Gross margin increased to 25% from 1%, with lower depreciation, power costs, equipment-sales costs, and stock-based compensation contributing. The comparison also reflects substantial 2022 asset impairments.
- Operating results improved sharply, but the 2023 net loss included $191.1 million of reorganization items and $86.2 million of net interest expense. The 2022 net loss included $1.06 billion of goodwill and intangible impairment and $590.7 million of property and equipment impairment.
- Operating cash flow decreased to $65.1 million from $205.2 million. Capital expenditures were $16.2 million in 2023 versus $384.0 million in 2022.
Outlook, risks, contingencies, and unusual items
- Bankruptcy emergence and financing: The January 2024 reorganization canceled prior equity and issued new stock, warrants, contingent value rights, $150 million of secured notes, and $260 million of secured convertible notes. The company also entered an $80 million first-lien credit facility, with $20 million of delayed-draw capacity reported as undrawn, and miner-equipment financing. Management said available liquidity and expected operating cash flows should fund operations and debt service for at least 12 months. This is management’s assessment, not a guarantee.
- Debt costs and restrictions: New secured notes carry 12.5% interest; secured convertible notes carry 10% cash interest or an optional cash/stock interest structure. The credit agreement and indentures impose covenants, including financial maintenance requirements and limits on additional debt, asset sales, and distributions.
- Bitcoin economics: Bitcoin price, mining difficulty, network hash rate, power prices, and the April 2024 block-reward halving may materially affect mining revenue and margins. Debt terms require sale of mined bitcoin shortly after receipt, limiting participation in later price appreciation.
- Customer and supplier concentration: The largest hosting customer represented 49% of hosting revenue and 11% of total revenue in 2023. Mining equipment supply depends heavily on Bitmain.
- Expansion and contracts: In March 2024, Core announced a multi-year CoreWeave hosting agreement for up to 16 MW, with potential revenue exceeding $100 million; this is a post-year-end announcement and is conditional on delivery and performance. A new Austin data-center lease has an eight-year term and expected payments of $97.8 million.
- Internal controls: Management concluded internal control over financial reporting and certain disclosure controls were ineffective at year-end due to material weaknesses in IT change management, user access/segregation of duties, and timely GAAP recording. Remediation is underway; effectiveness has not yet been established. The auditor did not provide an ICFR effectiveness opinion.
- Other unusual items and contingencies: Reorganization items included bankruptcy professional fees, DIP financing costs, post-petition interest and fees, and creditor settlement gains and losses. The filing describes pending shareholder, employment, and contract claims; outcomes and potential losses are uncertain. Digital assets are uninsured and are held substantially with two third-party services.
- Guidance: The filing does not provide formal revenue or earnings guidance. Forward-looking statements are subject to substantial uncertainty.
Most important facts for investors to verify
- Post-emergence cash, debt balances, debt-service schedule, covenant headroom, and compliance with minimum-liquidity requirements.
- Whether operating cash flow and the stated 12-month liquidity assessment hold up after required debt payments, settlements, and planned capital spending.
- Realized mining economics after the halving, including bitcoin produced, network difficulty, power costs, curtailments, and fleet efficiency.
- Execution, timing, financing, and customer commitments for the CoreWeave contract and Austin data-center lease.
- Progress in remediating material weaknesses and whether controls operate effectively over a sufficient testing period.
- Potential dilution from warrants, convertible notes, contingent value rights, and the planned management incentive plan, which may reserve up to 10% of post-emergence equity on a fully diluted basis.
