Pursuant to a reclassification exempt under Rule 16b-7, each share of Common Stock was reclassified into one share of Class B Common Stock immediately prior to the completion of the Issuer's initial public offering of Class A Common Stock (the "IPO"). | Each share of Class B Common Stock is convertible into one share of Class A Common Stock at the option of the holder. | The shares of Class B Common Stock automatically convert to shares of Class A Common Stock on a 1:1 basis on or prior to September 19, 2035 as set forth in the Issuer's amended and restated certificate of incorporation. | Each restricted stock unit, or RSU, represents a contingent right to receive one share of Issuer Common Stock. | The RSUs vest as follows: 150,000 RSUs vest on April 1, 2026 and the remaining 200,000 vest on April 1, 2027. | Each RSU represents a contingent right to receive one share of Issuer Class B Common Stock. | The RSUs vest in 15 equal quarterly installments beginning on October 1, 2025. | Each performance-based RSU, or PSU, represents a contingent right to receive one share of Issuer Common Stock. | The PSUs vest upon the Issuer's achievement of certain market capitalization milestones: 1/3 of the PSUs vest upon the Issuer's achievement of each of a $10 billion market capitalization, $12.5 billion market capitalization, and $15 billion market capitalization. Market capitalization will be measured based on the highest 60-day trading average per share ending during the applicable month, as reasonably determined by the board of directors or board committee. | Each PSU represents a contingent right to receive one share of Issuer Class B Common Stock. | The shares subject to the option are fully vested and immediately exercisable.
