Strategy has successfully raised approximately $4.7 billion through its perpetual floating-rate preferred shares, known as STRC, which are positioned above common stock and some debt in terms of shareholder priority. These shares, which do not guarantee principal protection, offer a current dividend yield of about 11.5%, adjustable monthly. The company has a reserve of $2.25 billion, sufficient to cover dividends for approximately two years. The primary risks involve long-term sustainability and expansion of the offering.
