TL;DR:
MARA Holdings executed between March 4 and 25 a massive bitcoin sale that reconfigured its capital structure. The miner sold 15,133 BTC in exchange for approximately $1.1 billion, directing the bulk of the proceeds toward repurchasing its own debt at a discount.
The transaction involved the private repurchase of two series of 0.00% convertible senior notes: $367.5 million of the tranche maturing in 2030, acquired for $322.9 million, and $633.4 million of the tranche maturing in 2031, acquired for $589.9 million. The average discount of 9% on face value generated $88.1 million in value for the company. The remaining proceeds from the sale will be directed toward general corporate purposes and operational liquidity.
The impact on the firm’s balance sheet was significant: total convertible debt was reduced from approximately $3.3 billion to $2.3 billion, a contraction of 30%. Furthermore, by retiring those instruments from the market, MARA eliminated a potential source of dilution for its shareholders, given that convertible notes can be transformed into ordinary shares if certain conditions are met. The company’s shares rose 10% in pre-market trading on Thursday, March 26, trading near the top of their one-month range.

Fred Thiel, chairman and chief executive officer of MARA, presented the transaction as a strategic capital allocation decision. “This transaction enhances financial flexibility and increases strategic options as we expand beyond bitcoin into digital energy and AI/HPC infrastructure,” Thiel stated in the official press release.
The sale also marked an inflection point in the company’s treasury policy, which until now had combined holding mined BTC with acquiring additional bitcoin through debt. MARA remains the sixth largest Bitcoin mining pool in the world, with a total capacity exceeding 66 EH/s, and produces approximately 4% of the network’s daily blocks.
Currently holding approximately 38,689 BTC in reserve and carrying considerably lighter debt, the company aims to strengthen its position in energy infrastructure and artificial intelligence as long-term growth pillars.
