Core Scientific, Inc. (NASDAQ: CORZ), a leader in digital infrastructure for bitcoin mining and HPC, today announced financial results for the fiscal second quarter of 2024. Net loss was $804.9 million, as compared to a net loss of $9.3 million for the same period in 2023. Total revenue was $141.1 million, as compared to $126.9 million for the same period last year. Operating income was $6.6 million, as compared to $9.5 million for the same period in 2023. Adjusted EBITDA was $46.0 million, as compared to $45.0 million for the same period in the prior year. Second quarter Net loss resulted from a net $796 million mark-to-market adjustment in the value of our tranche 1 and tranche 2 warrants and other contingent value rights required as a result of the significant quarter-over-quarter increase in the value of our equity.

“We continue to demonstrate progress on the execution of our strategy to maximize the value of our high-power digital infrastructure portfolio through bitcoin mining and high-performance computing,” said Adam Sullivan, Core Scientific Chief Executive Officer. “Key achievements in and after the quarter include successfully navigating the April halving and emerging with favorable quarterly cash cost to mine of approximately $29,900 per bitcoin, converting $260 million in convertible notes during and shortly after the end of the quarter, commencing HPC hosting operations and revenue generation at our 16-megawatt Austin data center, and signing long-term contracts to host 382 megawatts of high-performance computing with our current client. These long-term contracts represent total potential revenue of approximately $6.7 billion over 12 years.”

“Our highly experienced digital infrastructure team is preparing to modify several of our data centers to support HPC hosting, including working diligently to address supply chain challenges as they emerge. We also continue discussions with our existing client and other counterparties to contract our remaining 118 megawatts of infrastructure for HPC hosting while we work to execute on our pipeline of opportunities to increase our 1,200 MW of contracted power. We are building meaningful momentum in each of our businesses as we enter the second half of the year and believe we are well positioned to drive continued value creation for our shareholders,” Mr. Sullivan added.

Fiscal Second Quarter 2024 Financial Results (Compared to Fiscal Second Quarter 2023)

Total revenue for the fiscal second quarter of 2024 was $141.1 million, and consisted of $110.7 million in digital asset self-mining revenue, $24.8 million in digital asset hosted mining revenue and $5.5 million in HPC hosting revenue.

Digital asset self-mining revenue in excess of mining cost of revenue for the fiscal second quarter of 2024 was $30.7 million (28% gross margin), as compared to $30.2 million (31% gross margin) for the same period in the prior year, an increase of $0.5 million. The increase in Digital asset self-mining revenue in excess of Digital asset mining cost of revenue was driven by a 134% increase in the price of bitcoin, a 28% increase in our self-mining hash rate and an increase in the number of mining units deployed, offset by the 52% decrease in bitcoin mined due to the halving and higher network difficulty.

Digital asset hosted mining revenue in excess of hosting cost of revenue for the fiscal second quarter of 2024 was $7.4 million (30% gross margin), as compared to $6.7 million (23% gross margin) for the same period in the prior year, an increase of $0.7 million. The increase in Digital asset hosted mining revenue in excess of Digital asset hosted mining cost of revenue was primarily due to a larger share of more profitable hosting arrangements.

HPC hosting revenue in excess of HPC hosting cost of revenue for the fiscal second quarter of 2024 was $0.6 million (11% gross margin). HPC hosting started operations during the fiscal second quarter of 2024. HPC hosting costs consisted primarily of lease expense and direct electricity costs.

Operating expenses for the fiscal second quarter of 2024 totaled $31.4 million, as compared to $27.1 million for the same period in the prior year. The increase of $4.3 million was primarily attributable a $7.2 million increase in personnel and related expenses and $4.6 million of HPC startup costs incurred during the current period, partially offset by lower stock-based compensation of $6.5 million due to cancellations and forfeitures of equity-based awards.

Net loss for the fiscal second quarter of 2024 was $804.9 million, as compared to a net loss of $9.3 million for the same period in the prior year. Net loss for the fiscal second quarter of 2024 increased by $795.6 million driven primarily by a net $796.0 million mark-to-market adjustment on our warrants and other contingent value rights comprising a $827.7 million increase in the fair value of warrant liabilities, partially offset by a $31.7 million decrease in fair value of contingent value rights. These mark-to-market adjustments were driven by the increase in our stock price during the period. Also contributing to the increase in Net loss was a $14.8 million increase in Interest expense, net resulting from the Bankruptcy Court ordered stay on payment of pre-petition obligations, including interest during the same period in 2023, partially offset by $18.5 million in Reorganization items, net with no comparable activity for the same period in fiscal 2024 due to the Company’s emergence from bankruptcy during the first quarter 2024.

Non-GAAP Adjusted EBITDA for the fiscal second quarter 2024 was $46.0 million, as compared to Non-GAAP Adjusted EBITDA of $45.0 million for the same period in the prior year. This $1.0 million increase was driven by a $14.2 million increase in total revenue and a $1.1 million decrease in impairment of digital assets, partially offset by a $7.6 million increase in cash operating expenses, a $3.2 million increase in cash cost of revenue, a $2.0 million increase in realized losses on energy derivatives, a $0.9 million decrease in gain from sales of digital assets and a $0.6 million decrease in the change in fair value of digital assets.

You can identify forward-looking statements by the fact that they do not relate strictly to historical or current facts. These statements may include words such as “aim,” “estimate,” “plan,” “project,” “forecast,” “goal,” “intend,” “will,” “expect,” “anticipate,” “believe,” “seek,” “target” or other similar expressions that predict or indicate future events or trends or that are not statements of historical matters. All forward-looking statements are subject to risks and uncertainties that may cause actual results to differ materially, including:our ability to earn digital assets profitably and to attract customers for our digital asset and high performance compute hosting capabilities; our ability to perform under our existing colocation agreements, our ability to maintain our competitive position in our existing operating segments, the impact of increases in total network hash rate; our ability to raise additional capital to continue our expansion efforts or other operations; our need for significant electric power and the limited availability of power resources; the potential failure in our critical systems, facilities or services we provide; the physical risks and regulatory changes relating to climate change; potential significant changes to the method of validating blockchain transactions; our vulnerability to physical security breaches, which could disrupt our operations; a potential slowdown in market and economic conditions, particularly those impacting high performance computing, the blockchain industry and the blockchain hosting market; the identification of material weaknesses in our internal control over financial reporting; price volatility of digital assets and bitcoin in particular; the “halving” of rewards available on the Bitcoin network, affecting our ability to generate revenue; the potential that insufficient awards from digital asset mining could disincentivize transaction processors from expending processing power on a particular network, which could negatively impact the utility of the network and further reduce the value of its digital assets; the requirements of our existing debt agreements for us to sell our digital assets earned from mining as they are received, preventing us from recognizing any gain from appreciation in the value of the digital assets we hold; potential changes in the interpretive positions of the SEC or its staff with respect to digital asset mining firms; the increasing likelihood that U.S. federal and state legislatures and regulatory agencies will enact laws and regulations to regulate digital assets and digital asset intermediaries; increasing scrutiny and changing expectations with respect to our ESG policies; the effectiveness of our compliance and risk management methods; the adequacy of our sources of recovery if the digital assets held by us are lost, stolen or destroyed due to third-party digital asset services; the effects of our emergence from bankruptcy and our substantial level of indebtedness and our current liquidity constraints affecting our financial condition and ability to service our indebtedness.

Non-GAAP Financial Measures

(Unaudited)

Adjusted EBITDA is a non-GAAP financial measure defined as our net income or (loss), adjusted to eliminate the effect of (i) interest income, interest expense, and other income (expense), net; (ii) provision for income taxes; (iii) depreciation and amortization; (iv) stock-based compensation expense; (v) Reorganization items, net; (vi) change in fair value of energy derivatives; (vii) change in the fair value of warrant and contingent value rights, (viii) business or site startup costs which are not reflective of the ongoing costs incurred after startup, (ix) bankruptcy advisory costs incurred related to reorganization which are not reflective of the ongoing costs incurred in post-emergence operations, and (x) certain additional non-cash items that do not reflect the performance of our ongoing business operations. For additional information, including the reconciliation of net income (loss) to Adjusted EBITDA, please refer to the table below. We believe Adjusted EBITDA is an important measure because it allows management, investors, and our Board of Directors to evaluate and compare our operating results, including our return on capital and operating efficiencies, from period-to-period by making the adjustments described above. In addition, it provides useful information to investors and others in understanding and evaluating our results of operations, as well as provides a useful measure for period-to-period comparisons of our business, as it removes the effect of net interest expense, taxes, certain non-cash items, variable charges and timing differences. Moreover, we have included Adjusted EBITDA in this earnings release because it is a key measurement used by our management internally to make operating decisions, including those related to operating expenses, evaluate performance, and perform strategic and financial planning.

The above items are excluded from our Adjusted EBITDA measure because these items are non-cash in nature or because the amount and timing of these items are not related to the current results of our core business operations which renders evaluation of our current performance, comparisons of performance between periods and comparisons of our current performance with our competitors less meaningful. However, you should be aware that when evaluating Adjusted EBITDA, we may incur future expenses similar to those excluded when calculating this measure. Our presentation of this measure should not be construed as an inference that its future results will be unaffected by unusual items. Further, this non-GAAP financial measure should not be considered in isolation from, or as a substitute for, financial information prepared in accordance with accounting principles generally accepted in the United States (“GAAP”). We compensate for these limitations by relying primarily on GAAP results and using Adjusted EBITDA on a supplemental basis. Our computation of Adjusted EBITDA may not be comparable to other similarly titled measures computed by other companies because not all companies calculate this measure in the same fashion. You should review the reconciliation of net loss to Adjusted EBITDA below and not rely on any single financial measure to evaluate our business.

The following table reconciles the non-GAAP financial measure to the most directly comparable U.S. GAAP financial performance measure, which is net loss, for the periods presented (in thousands):
