Rhea-AI Filing Summary

Brendan F. Blumer filed Amendment No. 1 to his Schedule 13D on Bullish, reporting beneficial ownership of 39,166,869 Ordinary Shares, or 26.8% of the class. The percentage is based on 146,183,739 Ordinary Shares outstanding as of August 13, 2025, as stated in Bullish’s final prospectus.

Blumer directly holds 39,166,869 Ordinary Shares and is the beneficial holder of 1,976,563 Ordinary Shares through Buttonwood Investments 1, which he controls. Most of these Buttonwood shares (1,968,750) were transferred to optionholders on January 16, 2026 under Call Option Agreements, with the remaining 7,813 expected to be exercised by March 31, 2026.

Buttonwood has not yet received payment for 1,070,313 Call Option Shares, but Blumer, through Buttonwood, disclaims voting and dispositive ownership of those unpaid shares effective January 16, 2026. Blumer states he may increase or decrease his holdings over time, and he continues to serve on Bullish’s Board of Directors, which gives him influence over the company’s corporate activities.
