MARA Sold 15,133 Bitcoin for $1.1 Billion to Cut Debt

MARA Holdings sold 15,133 Bitcoin for about $1.1 billion between March 4 and March 25, using most of the proceeds to repurchase convertible notes, the company said on March 26.

The transactions covered roughly $1 billion of face value for $912.8 million in cash. MARA agreed to buy back two tranches:

• $367.5 million in principal on notes due in 2030, for $322.9 million in cash.
• $633.4 million in principal on notes due in 2031, for $589.9 million in cash.

MARA estimated that the repurchases would save $88.1 million before transaction costs. Pricing the transactions at about 9% below par amounts to roughly nine cents of cash saved for each dollar of principal retired. MARA said the repurchases would reduce convertible indebtedness by approximately 30%.

The Bitcoin sale did not consume the entire $1.1 billion. MARA reserved the balance for general corporate purposes. In operational terms, the company converted part of a Bitcoin-funded treasury position into cash while reducing its convertible obligations. The result is a smaller convertible debt load and cash retained for corporate purposes, rather than an exit from Bitcoin holdings.

Chairman and CEO Fred Thiel said the deal increased 'financial flexibility' as MARA expands beyond Bitcoin mining into digital energy and AI and high-performance computing infrastructure. The announcement places the repurchase alongside MARA's stated expansion plans, although it does not earmark the retained proceeds for a specific project.

What does the debt repurchase change for investors?

For creditors in the repurchased notes, the terms provide cash below face value. For MARA, the benefit is lower convertible indebtedness ahead of the 2030 and 2031 maturities, with estimated savings of $88.1 million before transaction costs. The company pays $912.8 million in cash to retire roughly $1 billion of principal.

For equity investors, the practical question is what this flexibility funds. MARA's stated ambitions extend beyond Bitcoin mining into digital energy and AI and high-performance computing infrastructure. The buyback gives those ambitions a larger cash cushion, but it also reduces the Bitcoin inventory available for other uses.

How much Bitcoin did MARA sell?

MARA sold 20,880 BTC during the first quarter at an average of $70,137 per coin and held 35,303 BTC on March 31. The 15,133-BTC disposal between March 4 and 25 represented roughly 72% of the quarter's disclosed sales.

The $70,137 figure is a quarterly average, not a separately disclosed execution price for the March sale. Investors should therefore avoid treating it as the realized price for all 15,133 BTC. The company disclosed only the approximately $1.1 billion in aggregate proceeds for that disposal.

MARA still held 35,303 BTC on March 31 after the first-quarter sales. That retained position means the debt reduction did not end the company's exposure to Bitcoin, even as it lowered its convertible borrowing burden.

The next checkpoint is execution: retained proceeds, the pace of AI and high-performance computing expansion, and the treatment of remaining convertible obligations before their 2030 and 2031 maturities.
