The quarterly loss was driven almost entirely by an $8.32 billion unrealized markdown on its bitcoin holdings under fair-value accounting. The company held 843,775 bitcoin as of July 26, up 25% from the start of the year. At current prices, the stash is worth roughly $54.8 billion, compared with an acquisition cost of $63.7 billion. The report came after a period of growing investor scrutiny on the firm over whether it can sustain an increasingly complex capital structure built around multiple classes of preferred stock, common equity and convertible debt. Executive Chairman Michael Saylor said the company remains focused on expanding what it calls its "Digital Credit" business despite weaker bitcoin prices.
