SIGNATURE
After reasonable inquiry and to the best of my knowledge and belief, I certify that the information set forth in this statement is true, complete and correct.
What ownership stake in BIXI does LMR report on this Schedule 13G?
LMR-affiliated entities report owning 1,250,000 BIXI Class A shares, or 5.5% of the class. This percentage is based on 22,770,000 Class A shares outstanding after BIXI’s IPO and related private placement completed in early December 2025.
Who are the reporting persons for the BIXI Schedule 13G filing?
The reporting group includes multiple LMR investment management entities plus Ben Levine and Stefan Renold. These individuals ultimately control the investment and voting decisions of the LMR investment managers for the BIXI securities held by LMR Multi-Strategy Master Fund and LMR CCSA Master Fund.
How are the 1,250,000 BIXI shares held by the LMR group structured?
The 1,250,000 Class A shares are held through two LMR funds, each owning 625,000 units. Each unit consists of one Class A ordinary share and half of a redeemable warrant, so each fund directly holds both shares and associated warrants linked to BIXI.
What percentage of BIXI does each LMR fund individually hold?
Each of LMR Master Fund and LMR CCSA Master Fund holds about 2.7% of BIXI’s Class A shares. Together they own 1,250,000 Class A ordinary shares, representing a combined 5.5% of the outstanding Class A shares following BIXI’s initial public offering.
What warrants related to BIXI does the LMR group hold?
Each LMR fund holds warrants to purchase 312,500 BIXI Class A shares at $11.50 per share. These warrants become exercisable 30 days after BIXI completes its initial business combination and will expire five years after that business combination or earlier upon redemption or liquidation.
Does the LMR group seek to influence control of BIXI with this stake?
The reporting group certifies the BIXI securities are held in the ordinary course and not to change or influence control. They also state the holdings are not connected with any transaction intended to affect control, aside from limited activities tied to director nomination rules.
