Risk Factors

  • No target selected yet — SPAC has 24 months to complete a business combination or liquidate
  • Significant dilution to public shareholders from founder shares and private placement warrants
  • Conflicts of interest: sponsor profits even if post-combination stock price declines
  • Shareholder redemption rights could reduce trust proceeds at time of business combination
