Strategy (formerly Micro) purchased 1,665 bitcoin for $142.7 million during the week of September 21–27 and repurchased $151.7 million of its STRC preferred stock, extending an active capital management program spanning both its bitcoin treasury and its preferred share structure. Following the latest purchase, the company's bitcoin holdings reached 847,666 BTC, acquired for a combined $63.95 billion. The moves were disclosed in a Form 8-K filed with the U.S. Securities and Exchange Commission on September 28, the filing vehicle public companies use to report material corporate events to investors.

Weekly Bitcoin Purchase Funded by ATM Share Sales

Between September 21 and September 27, Strategy acquired 1,665 BTC for $142.7 million, a figure that includes fees and expenses. According to its September 28 Form 8-K filing, the acquisition carried an average purchase price of $85,681 per bitcoin.

The purchase was funded directly through proceeds from the company's MSTR at-the-market (ATM) offering program, a sales mechanism that lets an issuer sell registered shares into the market incrementally at prevailing prices rather than in a single underwritten offering. Over the same period, Strategy sold 1,469,165 MSTR shares, generating $246.2 million in net proceeds after sales commissions. Of that amount, $142.7 million was directed toward bitcoin purchases, while another $103.5 million went toward STRC share repurchases. Together, the two uses accounted for the full $246.2 million raised, fully allocating the week's equity sales across the two programs.

As of September 27, the firm held 847,666 BTC acquired for an aggregate $63.95 billion, the largest bitcoin treasury disclosed by any publicly traded company. With fees and expenses included, the average purchase price across the entire bitcoin position stands at $75,437 per BTC, a blended figure built up across the program's history that sits below this week's $85,681 average.

Strategy also retains substantial capacity to raise additional common equity. Approximately $18.84 billion of MSTR shares remained available for issuance and sale under the ATM program as of September 27 — the disclosed headroom under the same channel used to fund this week's activity.

STRC Buyback Uses Share Sale Proceeds and USD Cash

Alongside the bitcoin acquisition, Strategy continued buying back its Variable Rate Series A Perpetual Stretch Preferred Stock (STRC). During the week, the company repurchased 1,534,530 STRC shares for an aggregate purchase price of $151.7 million, transactions that reduce the outstanding share count of that security.

MSTR stock sales funded $103.5 million of that total, while the remaining $48.1 million was covered with USD Cash. No shares of STRF, STRK, STRD, or MSTR were repurchased during the reporting period, making STRC the only security the company bought back in the frame.

Following the STRC transactions, $723.5 million remained available under Strategy's digital credit securities repurchase program. Separately, the company maintains $1 billion in authorized capacity under its MSTR stock repurchase program. Those remaining authorizations, together with the $18.84 billion of ATM capacity, define the disclosed limits of the company's current capital framework, with Form 8-K filings serving as the channel through which updates to these totals are reported.

Reserve Funds Covered $22.1 Million in Preferred Dividends

The disclosure also provided updated figures for the USD Reserve and USD Cash, two pools serving distinct roles within Strategy's capital framework. As of September 27, the USD Reserve held $5.02 billion and is primarily intended to cover preferred-stock dividends and interest on outstanding debt.

The firm also held $1 billion in USD Cash, which management can direct toward bitcoin purchases, reserve funding, and other corporate purposes. Combined, the two pools totaled $6.02 billion in USD assets, the figure Saylor cited in his September 28 post above. During the reporting period, Strategy used $22.1 million from its USD Reserve to pay preferred-stock dividends, a direct application of the reserve's stated role.
