8-K Impact 6/10 8-K

$MSTR · Strategy Inc

September 21, 2026 · AI-analyzed SEC filing

Strategy Inc filed an 8-K disclosing its weekly bitcoin acquisition and capital markets update. The company purchased 950 BTC for $75.7 million at an average price of $79,670, bringing total holdings to 846,000 BTC with a $63.80 billion aggregate cost basis. Additionally, Strategy repurchased 1,771,238 shares of STRC preferred stock for $174.0 million, leaving $875.1 million remaining on the preferred repurchase program and $1.0 billion on the MSTR common stock buyback. USD Reserve and USD Cash balances stood at $5.04 billion and $1.05 billion, respectively.

Extended-hours trading shows MSTR at $166.26, up 8.02% from the regular-session close of $153.91, reflecting positive reaction to continued BTC accumulation and capital deployment. Markets were closed at filing; this after-hours move captures the initial response.

Strategy's weekly disclosure confirms continued BTC accumulation at elevated prices while balancing $249.7M in combined capital deployment across bitcoin and preferred stock buybacks.

Strategy continues its bitcoin treasury playbook, now holding 846,000 BTC — roughly 4% of total bitcoin supply — while simultaneously managing a multi-tranche preferred stock capital structure and active buyback programs.

BTC purchased at $79,670 average — if bitcoin price declines below this level, Strategy faces unrealized losses on newly acquired coins. The $63.80B aggregate BTC cost basis against a $50.92B market cap creates concentrated digital-asset exposure.
