State below in reasonable detail why Forms 10-K, 20-F, 11-K, 10-Q, 10-D, N-SAR, N-CSR, or the transition report or portion thereof, could not be filed within the prescribed time period.


As previously disclosed on the Current Report on Form 8-K filed by Marathon Digital Holdings, Inc. (the “Company”) on February 22, 2023, the Company received a comment letter from the Corporation Finance Staff of the Securities and Exchange Commission relating to, among other things, certain accounting matters as described further below.


On February 27, 2023, the Company’s Audit Committee of the Board of Directors, after consultation with Marcum LLP, the Company’s independent auditor, concluded that due to certain accounting errors, as described below, the previously issued audited consolidated financial statements contained in the Company’s Annual Report on Form 10-K for the fiscal year ended December 31, 2021 and the previously issued unaudited condensed consolidated financial statementsfor the interim periods in 2022 and 2021 as contained in the Company’s Quarterly Reports on Form 10-Q for the fiscal periods ended March 31, 2021 and 2022, June 30, 2021 and 2022 and September 30, 2021 and 2022 (the “Impacted Financial Statements”) should no longer be relied upon. Similarly, related earnings releases and other financial communications for these periods should no longer be relied upon. The Company intends to correct the errors and will be restating the Impacted Financial Statements.


Management and the Audit Committee have discussed these matters with Marcum LLP.


As a result of receiving the SEC comments on February 22, 2023 and the Audit Committee’s determination to restate the Impacted Financial Statements, the Company is unable to complete and file its Annual Report on Form 10-K for the fiscal year ended December 31, 2022 (“2022 Form 10-K”) and to make the required corrections to its financials and accompanying disclosures for the Impacted Financial Statements by the filing deadline for the Company’s 2022 Form 10-K of March 1, 2023.


Among the restatement issues are:


Impairment of digital assets: The Company’s digital assets (bitcoin) are indefinite lived intangible assets within the scope of FASB ASC 350 – Intangible Assets Goodwill and Other (“ASC 350”) and as such, are subject to impairment testing on an annual basis or more frequently if events or changes in circumstances indicate it is more likely than not that the asset is impaired in accordance with ASC 350-30-35-18.


The Company recently determined that its method of calculating impairment on a daily basis using a standard cutoff time was not in compliance with the ASC 350-30-35-19 requirement to recognize impairment whenever carrying value exceeds fair value, which effectively calls for the intraday low price to be utilized in calculating impairment whenever events or changes in circumstances indicate it is more likely than not that the asset is impaired.




Operation of a bitcoin mining pool that included third party participants: In late 2021 and early 2022, the Company operated a bitcoin mining pool that included a small number of unrelated third-party participants. The Company accounts for revenues based on ASC Topic 606, Revenue from Contracts with Customers (ASC “606”) and had determined that in its capacity as the operator of a mining pool that included third parties, it acted as an agent. As a result, the Company recorded revenues on a net basis, subtracting any revenue allocated to the third-party pool participants from its revenue as the operator of the pool.


The Company recently determined that its assessment that it acted as an Agent in operating the third-party mining pool was incorrect and that it should have concluded that it was acting as a principal in its capacity as the pool operator. The effect of this change from Agent to Principal is that the Company should have recorded revenue from the pool on a gross basis with an offsetting cost of revenue to reflect amounts allocated to third party participants.


The Company estimates that both its revenues and its cost of revenues for the year ended December 31, 2021 were understated due to the “net” vs. “gross” presentation of revenues in its financial statements. As a result, both revenues and cost of revenues, energy, hosting and other are expected to increase upon completion of this restatement for 2021. There will also be minor increases to revenues and cost of revenues, energy, hosting and other in previously issued interim financial statements in both 2021 and 2022. The restatement of the Impacted Financial Statements is not expected to have any impact on total margin, operating income or net income in 2021 or in any of the interim periods in 2021 or 2022. The Company no longer operates a pool that includes third parties.


The information set forth herein solely refers to restatement issues in the Impacted Financial Statements and does not reflect any changes in accounting policy.
