Bitcoin miner MARA Holdings (NASDAQ: MARA) has laid off approximately 15% of its workforce, largely due to the shrinking margins, rising energy costs, and increased competition. The move comes just days after the company reported selling $1.1 billion in Bitcoin. The layoffs are part of a strategy to transition from a pure-play Bitcoin miner to a high-performance computing infrastructure company. Affected employees will reportedly receive one month of paid leave through April 30, 13 weeks of severance pay, and accrued PTO. The financial impact of these decisions is stark, with MARA reporting a loss of approximately $1.,0919 in the fourth quarter of 2025.
