Marathon Digital Holdings Announces Bitcoin Production and Mining Operation Updates for October 2023

- Produced 1,202 BTC in October 2023 and 9,812 BTC Year-to-Date

- Garden City Energization Underway; Full 4.1 EH/s Expected by November Month-End

- Combined Unrestricted Cash and Bitcoin Was $620 Million as of October 31, 2023

Fort Lauderdale, FL, Nov. 03, 2023 (GLOBE NEWSWIRE) -- Marathon Digital Holdings, Inc. (NASDAQ:MARA) ("Marathon" or "Company"), a leader in supporting and securing the Bitcoin ecosystem, today published unaudited bitcoin (“BTC”) production and miner installation updates for October 2023.

Management Commentary
“In October, we increased our energized hash rate 1% to 19.2 exahashes as the facility in Garden City, Texas, where we have 4.1 exahashes of miners installed, began to come online,” said Fred Thiel, Marathon’s chairman and CEO. “Once this facility is fully operational later this month, we will have surpassed our 23 exahash target and solidified Marathon as the largest publicly traded Bitcoin miner in North America.

“By increasing our hash rate and continuing to improve our operations at the facility in McCamey, Texas and elsewhere, we earned 4.0% of the total Bitcoin network’s available miner rewards and produced 1,202 bitcoin in October. This total includes 18 bitcoin from our 20% share of the JV in Abu Dhabi. We now have 2.3 exahashes online in Abu Dhabi as our second, larger facility in Masdar City has begun powering up. We continue to expect the full 7.0 exahashes in the UAE to be online by year-end.

“We have also been exploring new methods of mining that we believe may allow us to further diversify our operations, reduce our energy costs, and increase our sustainable energy mix. We recently announced a pilot project in Utah that is exclusively powered by landfill methane gas. Naturally produced methane is often stranded, and Bitcoin miners like Marathon are uniquely positioned to help capture and convert this environmentally harmful gas into clean, renewable energy. We look forward to sharing more of the many innovative mining projects that we are exploring in the months ahead.”

1. Defined as the total amount of block rewards including transaction fees that Marathon earned during the period divided by the total amount of block rewards and transaction fees awarded by the Bitcoin network during the period.
2. Defined as the amount of hash rate that could theoretically be generated if all miners that have been energized are currently in operation (includes miners that are temporarily offline for maintenance or similar reasons). Hash rates are estimates based on the manufacturers' specifications. All figures are rounded.
3. Defined as the average hash rate that was actually generated during the month from all operational miners. All figures are estimates and are rounded.
4. Defined as the sum of energized hash rate (see above) and hash rate that has been installed but is not yet energized (e.g., miners are in containers but not energized). Hash rates are estimates based on the manufacturers' specifications. All figures are rounded.

The Company’s average fleet efficiency, based on manufacturers’ specifications, was 25.2 J/TH (joules per terahash) as of November 1, 2023. Once fully deployed, Marathon’s U.S. fleet efficiency is expected to be approximately 24 J/TH, according to the manufacturers’ specifications.

Investor Notice
Investing in our securities involves a high degree of risk. Before making an investment decision, you should carefully consider the risks, uncertainties and forward-looking statements described under "Risk Factors" in Item 1A of our most recent Annual Report on Form 10-K for the fiscal year ended December 31, 2022, filed with the SEC on March 16, 2023. If any of these risks were to occur, our business, financial condition or results of operations would likely suffer. In that event, the value of our securities could decline, and you could lose part or all of your investment. The risks and uncertainties we describe are not the only ones facing us. Additional risks not presently known to us or that we currently deem immaterial may also impair our business operations. In addition, our past financial performance may not be a reliable indicator of future performance, and historical trends should not be used to anticipate results in the future. Future changes in the network-wide mining difficulty rate or Bitcoin hash rate may also materially affect the future performance of Marathon's production of bitcoin. Additionally, all discussions of financial metrics assume mining difficulty rates as of November 2023. See "Forward-Looking Statements" below.

Forward-Looking Statements
Statements made in this press release include forward-looking statements within the meaning of Section 27A of the Securities Act of 1933, as amended, and Section 21E of the Securities Exchange Act of 1934. Forward-looking statements can be identified by the use of words such as “may,” “will,” “plan,” “should,” “expect,” “anticipate,” “estimate,” “continue,” or comparable terminology. Such forward-looking statements are inherently subject to certain risks, trends and uncertainties, many of which the Company cannot predict with accuracy and some of which the Company might not even anticipate and involve factors that may cause actual results to differ materially from those projected or suggested. Readers are cautioned not to place undue reliance on these forward-looking statements and are advised to consider the factors listed above together with the additional factors under the heading “Risk Factors” in the Company's Annual Reports on Form 10-K, as may be supplemented or amended by the Company's Quarterly Reports on Form 10-Q.
