• Increased BTC Holdings to 17,381 BTC; Total Cash and BTC of $1.6B as of March 31, 2024
• Average Operational Hash Rate Increases 4% M/M to 18.3 EH/s

Fort Lauderdale, FL, April 04, 2024 (GLOBE NEWSWIRE) -- Marathon Digital Holdings, Inc. (NASDAQ: MARA) ("Marathon" or "Company"), one of the world’s largest publicly traded Bitcoin miners and a leader in supporting and securing the Bitcoin ecosystem, today published unaudited bitcoin (“BTC”) production and miner installation updates for March 2024.

Management Commentary
"Throughout the first quarter, our Bitcoin production has been impacted by unexpected equipment failures, transmission line maintenance, and higher than anticipated weather-related curtailment across multiple sites," said Fred Thiel, Marathon's chairman and CEO. "After maintenance issues at Garden City were addressed, the site experienced higher than anticipated curtailment in March. At Granbury, McCamey, and Ellendale, we are continuing to work through transformer issues that have reduced capacity at those sites below historical norms.

"While the site in Ellendale was briefly recovered and re-energized at the end of February, it had to be brought back down due to the persistence of quality issues with the transformers sourced at the site. The demonstrated complexity of re-energizing Ellendale, along with the latest information and recent progress, indicates that capacity at this site is likely to be gradually increased over the coming months. Applied Digital is using its best commercially reasonable efforts to shorten and pull up the energization timeline.

"While our hosting provider continues to swap in newly acquired transformers and bring capacity at Ellendale back online, we have continued to focus on optimizing our performance at other sites. In March, we began relocating miners from Ellendale to take advantage of the additional capacity we recently acquired through our strategic acquisitions of sites in Texas and Nebraska. We are also preparing to transition part of Granbury to immersion to optimize performance. Despite the challenges, we increased our average operational hash rate by 4% in March to 18.3 exahash, and we increased our bitcoin production 7% to 894 bitcoin. We now have 17,381 BTC on our balance sheet, and our combined cash and bitcoin holdings are approximately $1.6 billion.

"As Ellendale is gradually brought back online, we intend to further develop our Bitcoin mining portfolio, which is growing to approximately 1.1 gigawatts of capacity diversified across 11 sites on three continents, and leveraging our recently announced technology innovations, like our two-phase immersion cooling system, to optimize performance and expand our position as a leader in converting energy into economic value."

Operational Highlights and Updates
Figure 1: Operational Highlights

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 including miners that may be temporarily offline. 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 not yet energized. Hash rates are estimates based on the manufacturers' specifications. All figures are rounded.
5. These metrics are MaraPool only, do not include the joint ventures.

In March, Marathon energized approximately 4,000 additional miners (c. 0.4 EH/s). Once the current transition of 9,500 miners from Ellendale to Garden City is complete, Marathon's operating fleet will increase to approximately 235,000 Bitcoin miners, theoretically capable of producing 29.8 EH/s. Hash rate figures are calculated according to the manufacturers' specifications.

As of March 31, 2024 the Company holds a total of 17,381 unrestricted BTC. Marathon opted to sell 440 bitcoin in March. The Company still intends to sell a portion of its bitcoin holdings in future periods to support monthly operations, manage its treasury, and for general corporate purposes.

Financial Highlights and Updates
Figure 3: Financial Highlights

Marathon held $324.3 million in cash and cash equivalents on its balance sheet at month end, all of which was unrestricted. During March, the combined balance of unrestricted cash and cash equivalents and bitcoin increased from $1,461.4 million to $1,563.4 million at March 31, 2024. In anticipation of the next Bitcoin network halving, the Company continues to build liquidity on the balance sheet to capitalize on strategic opportunities, including industry consolidation.
