• Increased Operational Hash Rate 9% to 15.2 EH/s and Installed Hash Rate 13% to 20.1 EH/s in May 2023
• Raised nearly $800,000 for Bitcoin Core Developers in Collaboration with Brink

FORT LAUDERDALE, Fla., June 02, 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 May 2023.

Management Commentary
“We produced a record 1,245 bitcoin in May, up 77% from last month and 366% from May 2022,” said Fred Thiel, Marathon’s chairman and CEO. “The increased production was due to an increased hash rate and a significant increase in transaction fees, which accounted for approximately 11.8% of the total bitcoin we earned in the last month. The emergence of Ordinals significantly increased transaction fees in May, which in some cases, were so high that they exceeded the 6.25 BTC block reward. With our scale and our improved uptime during the month, we were able to capitalize on this opportunity. While such abnormally high transaction fees are historically rare, we believe these events can serve as a positive sign for the future of mining economics.

“In May, we increased our operational hash rate 9% month-over-month to 15.2 exahashes, and we increased our installed hash rate 13% month-over-month to 20.1 exahashes. With the construction of Applied Digital’s facility in Ellendale, ND progressing and optimizations across our fleet continuing, we believe we are on track to reach our 23 EH/s target near the middle of this year.

“Also in May, we announced that we were joining forces with Brink to raise up to $1 million to support Bitcoin Core developers. In less than four days, we collectively raised nearly $800,000 for Bitcoin Core developers, $500,000 of which is Marathon’s contribution. We are incredibly grateful to the Bitcoin community for rallying behind this initiative to support the volunteers who maintain the open-source protocol on which we all depend. We encourage every Bitcoiner and Bitcoin-related company to support the Bitcoin Core developers and join us in closing the gap to raise $1 million for the Bitcoin Core developers.”

Operational Highlights and Updates

Figure 1: Operational Highlights

In May, approximately 5,500 of Marathon’s Bitcoin miners (c. 0.75 EH/s) were newly energized at Applied Digital’s facilities in North Dakota. Approximately 5,300 S19 XPs (c. 0.72 EH/s) were newly energized in Ellendale, ND. The remaining units were energized at the Jamestown, ND, facility, where Marathon’s first domestic deployment of immersion mining is well underway.

As a result, the Company’s operating fleet increased to approximately 133,600 Bitcoin miners, theoretically capable of producing approximately 15.2 EH/s, according to the manufacturer’s specifications, as of June 1, 2023.

Once all of Marathon’s previously purchased miners are installed, approximately 66% of the Company’s hash rate is expected to be generated by S19 XPs, which are approximately 30% more energy efficient than the prior generation of mining rigs.

Financial Highlights and Updates

Figure 2: Financial Highlights

As of June 1, Marathon holds a total of 12,259 BTC, all of which are unrestricted. The Company opted to sell 554 BTC during the month of May and intends to sell a portion of its bitcoin holdings in future periods to support monthly operations, manage its treasury, and for general corporate purposes. The Company ended the month with $97.3 million in unrestricted cash and cash equivalents on its balance sheet.

Donation for Bitcoin Core Developers in Collaboration with Brink
On May 18, 2023, Marathon and Brink launched a joint initiative to raise up to $1 million to support Bitcoin Core developers. Marathon pledged to match donations up to an aggregate of $500,000 through 2023, for a total potential donation amount of $1 million (when combined with third party donations). The Company committed to matching all donations (up to a $500,000 maximum donation from Marathon) during the Bitcoin 2023 conference on a two-for-one basis.

On May 22, 2023, four days after the campaign’s inception, Marathon successfully fulfilled its matching pledge. While this accomplishment marks a significant milestone in the campaign, the goal of $1 million has yet to be achieved. Marathon and Brink are now encouraging the rest of the Bitcoin community to contribute towards this important cause to ensure Bitcoin Core developers can continue their essential work of maintaining and strengthening the Bitcoin network.

Additionally, all discussions of financial metrics assume mining difficulty rates as of June 2023. See "Forward-Looking Statements" below.
