Strategy (MSTR), led by executive chairman Michael Saylor, has added another 13,390 bitcoin (BTC) to its treasury, reaffirming its position as the largest corporate holder of the cryptocurrency.

According to a filing released Monday, the company spent approximately $1.34 billion on the latest purchase at an average price of $99,856 per BTC. The acquisition lifts Strategy’s total bitcoin holdings to 568,840 BTC—now valued at over $59 billion with bitcoin trading near $104,000.

The company’s average cost basis across its total stack now sits at $69,287 per bitcoin.

To finance the purchase, Strategy leveraged two capital-raising vehicles: an at-the-market (ATM) equity offering and the issuance of preferred shares. Between May 5 and May 11, the firm raised $1.31 billion through sales of its Class A common stock and issued 273,987 shares of its Series STRK preferred stock.

The move follows the company’s recent Strategy Conference and reinforces its long-term bullish stance on bitcoin. MSTR shares are up 2% in pre-market trading following the announcement.
