On January 22, 2026, through a share capitalization, the Company issued an additional 1,150,000 Founder Shares to the Sponsor, resulting in the Sponsor holding an aggregate of 6,900,000 Founder Shares. All share and per share amounts have been retroactively presented. The Founder Shares included an aggregate of 900,000 shares subject to forfeiture if the over-allotment option is not exercised in full by the underwriters.

As such, the 900,000 Founder Shares are no longer subject to forfeiture (Note 5).
