Michael Saylor's Strategy has resumed its Bitcoin (BTC) purchases after a two-week hiatus, adding to its corporate stash while continuing to repurchase shares of its STRC perpetual preferred stock.

In a Form 8-K filing with the United States Securities and Exchange Commission (SEC) published on Monday, the company disclosed that it acquired 950 BTC for roughly $75.7 million between Monday and Sunday, paying an average of $79,670 per coin. The company routinely discloses its weekly Bitcoin purchases through these SEC filings, which are among the most closely tracked data points in the corporate Bitcoin treasury sector.

The latest purchase lifted Strategy's total holdings to 846,000 BTC, acquired at a cumulative cost of approximately $63.8 billion — an average of $75,416 per Bitcoin once fees and expenses are included. With Bitcoin changing hands at $84,925 at the time of publication, the company held an unrealized gain of about $8.05 billion on its position. Both the $79,670 average price paid for the new coins and the $75,416 blended cost across all holdings sit below the market price at publication, which is what underpins the unrealized gain.

The renewed accumulation comes as Strategy balances its Bitcoin-buying program against the management of a growing roster of preferred securities and cash reserves measured in the billions of dollars.

Shares of Strategy, the world's largest publicly traded Bitcoin treasury company, climbed 7.4% to $165.2 in Monday pre-market trading, according to Yahoo Finance data. Strive, the fifth-largest corporate holder of Bitcoin, announced purchases of its own on the same day, saying it added 1,355 BTC last week to bring its total to 26,355 coins. Strive's shares rose 6.44% to $32.03, according to its own SEC filing. The same-day disclosures show that the largest and fifth-largest corporate holders of Bitcoin remained active buyers during the same week.

Strategy spends $174 million repurchasing STRC

Alongside its renewed Bitcoin buying, Strategy bought back about 1.77 million shares of its STRC perpetual preferred stock for $174 million during the same week. STRC gained 0.35% to $98.85 in Monday pre-market trading. Buybacks of this kind return capital to preferred shareholders and reduce the share count on which future dividends are paid.

The company said $875.1 million remains available under its preferred-stock repurchase program, while $1 billion is still untapped under its MSTR share repurchase program. Strategy also reported no sales under its at-the-market offering programs between Sept. 14 and Sept. 20, meaning it raised no new funds through those channels during the period.

Strategy's deployable cash declines

Strategy's "USD Cash" balance fell nearly 20% week over week to $1.05 billion from $1.30 billion, when the company reported its previous cash balance. Its separate "USD Reserve" slipped to $5.04 billion from $5.10 billion, reflecting $57.4 million in spending on preferred-stock dividends and interest on outstanding debt.

The company deploys USD Cash for broader treasury purposes, including Bitcoin purchases and capital management, while the USD Reserve is earmarked primarily to cover preferred-stock dividends and debt interest. With no new funds raised through at-the-market channels during the week, the trajectory of the USD Cash balance — alongside the remaining repurchase authorizations — will be a figure to track in Strategy's upcoming weekly filings.
