Exhibit 99.1 Marathon Digital Holdings Announces Bitcoin Production and Mining Operation Updates for September 2023 – Increased Monthly Average Operational Hash Rate 20% – Produced 1,242 BTC in September 2023 and 8,610 BTC Year-To-Date – Record Monthly Share of Miner Rewards at 4.3% – Combined Unrestricted Cash and Bitcoin Was $471 Million as of September 30, 2023 Fort Lauderdale, FL – October 4, 2023 – 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 September 2023.Management Commentary “We produced 1,242 bitcoin in September, which is a 16% increase from last month and a 245% increase from September of last year,” said Fred Thiel, Marathon’s chairman and CEO.“The increase in bitcoin production from August was due to improved uptime and decreased curtailment activity in Texas.In September, our share of the bitcoin network’s available miner rewards was a record 4.3%, up from 3.7% last month and the previous record of 4.1% in July 2023.
“Energization of the facility in Garden City, Texas is still pending.However, based on the latest updates, we believe the facility will start to come online this month.While our hosting provider completes the final steps to energize the site, the Marathon team has focused on increasing uptime at our other locations, especially in McCamey, Texas.
By upgrading equipment, leveraging our proprietary firmware, and making other technical improvements, we increased our U.S.average operational hash rate 20% month-over-month to 15.8 exahashes.We believe there is still room for improvement at our McCamey site, and we are working with our hosting provider to further increase uptime.“Outside the US, our joint venture in Abu Dhabi mined 50 bitcoin in September of which approximately 10 bitcoin is our share.Construction is nearly complete at our second, larger site, and we continue to expect the project’s full 7.0 exahashes to be online before year-end 2023.“In September, we opportunistically retired the majority of our convertible debt at a significant discount.
This accretive transaction creates shareholder value and positions Marathon to capitalize on any near-term turbulence in the Bitcoin mining sector.
With the next halving just over six months away, our balance sheet is now a source of strength that allows us to focus on further increasing efficiency and lowering costs.“Our primary focus is still growth.Now that we have reached our primary domestic growth target of 23 exahashes on an installed basis, we are evaluating multiple opportunities for our next 5 exahashes of hash rate capacity including international locations with low-cost renewable energy.We expect to announce specifics on our expansion plans in the weeks ahead.“Lastly, I’d like to remind our shareholders to vote in the upcoming Special Meeting of Shareholders, now scheduled for November 10, 2023.We adjourned the previous meeting because we did not receive enough votes to achieve a quorum.
We also recently provided more details about our Long-Term Incentive Plan or LTIP.Please note our LTIP is solely based on Marathon stock price performance relative to our closest peers which we believe to be fully aligned with shareholder interests.” Operational Highlights and Updates Figure 1: U.S.Operational Highlights |Metric||9/30/2023||9/30/2022||% Δ||9/30/2023||8/31/2023||% Δ| |Bitcoin Produced – U.S.Only||1,232||360||242||%||1,232||1,062||16||%| |Average Bitcoin Produced per Day||41.1||12.0||242||%||41.1||34.3||20||%| |Energized Hash Rate (EH/s)1||19.1||3.8||403||%||19.1||19.1||—%| |Average Operational Hash Rate (EH/s)2||15.8||NA||15.8||13.2||20||%| |Installed Hash Rate (EH/s)3||23.1||3.8||508||%||23.1||23.1||—%| 1.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.
2.Defined as the average hash rate that was actually generated during the month from all operational miners.
All figures are estimates and are rounded.3.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 October 1, 2023.Once fully deployed, Marathon’s U.S.fleet efficiency is expected to be approximately 24 J/TH, according to the manufacturers’ specifications.Figure 2: U.S.Operational Details by Site |Hash Rates in EH/s||Installed Hash Rate||Energized Hash Rate||Avg Operating Hash Rate||Avg % of Energized| |Site||State||Host||Aug 2023||Sep 2023||Aug 2023||Sep 2023||Aug 2023||Sep 2023||Aug 2023||Sep 2023| |McCamey||TX||US Bitcoin||7.8||7.7||7.8||7.7||4.0||5.8||51||%||75||%| |Ellendale||ND||Applied||7.6||7.7||7.6||7.7||6.6||6.6||87||%||86||%| |Garden City||TX||Applied||4.1||4.1||0.0||0.0||0.0||0.0||0||%||0||%| |Granbury||TX||US Bitcoin||1.9||1.9||1.9||1.9||1.1||1.5||56||%||81||%| |Jamestown||ND||Applied||1.4||1.4||1.4||1.4||1.3||1.2||89||%||84||%| Note: Table above does not include smaller sites or the joint venture in the UAE The Company continues to work with its hosting providers on improving efficiency and increasing uptime particularly in McCamey, Texas.
September saw marked improvement due to decreased curtailment and optimization efforts that included upgrading equipment, leveraging our proprietary firmware, and other technical improvements.Excluding curtailment, our staff has helped increase uptime in McCamey, Texas by approximately 20% between July and September.
