Strive shares rose as much as 10% on Monday after the company disclosed another Bitcoin purchase that brought its total holdings close to 20,000 BTC.

The company acquired 759 Bitcoin between June 15 and June 21 for nearly $50 million at an average price of about $65,850 per token, including fees and expenses.

The purchase increased Strive’s treasury from 19,105 BTC to 19,864 BTC, making it the seventh largest publicly traded corporate Bitcoin holder.

At Bitcoin’s Monday price near $64,400, the position was worth approximately $1.28 billion.

Strive has rapidly expanded its treasury in recent weeks. The company held just over 15,000 BTC in early May before adding 1,109 BTC later that month and another 2,500 BTC at the beginning of June.

It subsequently purchased 32 BTC during the week ended June 7 and another 73 BTC during the following week, bringing its holdings to 19,105 BTC before the latest acquisition.

The company funded the latest purchase through sales of Class A common stock and its Variable Rate Series A Perpetual Preferred Stock, which trades under the ticker SATA.

Strive reported $144.5 million in cash and cash equivalents as of June 18, up from $141.4 million on June 12.

The company also held 505,000 shares of Strategy’s STRC preferred stock, valued at approximately $44.7 million, down from $47.9 million the prior week.

Strive’s Class A share count increased by about 1.9 million during the period, while the number of outstanding SATA preferred shares rose by 315,595.

The company uses Bitcoin as its primary treasury asset and says its strategy is focused on increasing the amount of Bitcoin held per share over time.

Strive shares reached an intraday high of $16.39 before giving back most of the advance and trading near $15 later in the session.
