Bitcoin stacking company Strategy (NASDAQ:MSTR), which has just rebranded from its former name of MicroStrategy, has reported a net loss of $670.8 million for the fourth quarter.

The company reported fourth quarter revenue of $120.7 million, a 3% year on year fall. Meanwhile it said it had bought an additional 218,887 Bitcoin, bringing its holdings to 471,107 Bitcoin, worth over $45 billion, the largest of any corporation in the world.

Strategy’s expenses for Q4 rose almost 700% year on year to $1.1 billion as it commenced its “21/21 Plan”, which targets $42 billion in capital over the next three years, split equity and fixed-income securities, to buy more Bitcoin. The company said it had already completed $20 billion of that $42 billion capital plan, funding its Bitcoin purchases largely through senior convertible notes and debt.

Strategy CEO and president Phong Le said the firm is already “significantly ahead” of its initial timeline and is “well-positioned to further enhance shareholder value by leveraging the strong support from institutional and retail investors for our strategic plan.”

Strategy’s share price fell 3.3% during the Feb. 5 trading day to $336.70 and dropped another 0.72% in after-hours.
