Key risk factors

• Blank check company - no business combination target selected

  “We have not selected any business combination target and we have not, nor has anyone on our behalf, initiated any substantive discussions, directly or indirectly, with any business combination target.”

• Conflicts of interest with management

  “The low price that our sponsor, executive officers and directors (directly or indirectly) paid for the founder shares creates an incentive whereby our officers and directors could potentially make a substantial profit even if we select an acquisition target that subsequently declines in value and is unprofitable for public shareholders.”

• Issuance of additional shares dilution risk

  “We may issue additional Class A ordinary shares or preference shares to complete our initial business combination or under an employee incentive plan after completion of our initial business combination.”

• No protections of Rule 419 blank check offerings

  “Investors will not be entitled to protections normally afforded to investors in Rule 419 blank check offerings.”

• Cayman Islands incorporation - no public offering in Cayman

  “No offer or invitation, whether directly or indirectly, is being or may be made to the public in the Cayman Islands to subscribe for any of our securities.”
