MicroStrategy (MSTR) faces a potential liquidity crisis as its $900 million cash reserve is outweighed by $1.7 billion in annual dividend obligations on over $10 billion of issued preferred stock. The analyst expresses a bearish sentiment, suggesting a three-month "time-bomb" window before the company may be forced to sell BTC, issue more common stock, or cancel dividends. The capital structure is described as unsustainable due to the high 10-11.5% yield on preferred shares relative to the cash flow of the underlying software business.
