Explanation of responses 1 footnote

Footnote F1

Each performance stock unit ("PSU") represents a contingent right to receive shares of Strategy class A common stock of between 0% and 200% of the target number of units, with the percentage determined based on Strategy's relative total shareholder return ("TSR") as compared to the TSR of members of the Nasdaq Composite Index over a three-year performance period (March 17, 2026 to March 16, 2029). Vesting is subject to certification by Strategy's Compensation Committee of the level of achievement of the performance goal and the participant's continued service through that date. The "target" number of PSUs is reported on this Form 4.
