Key risk factors

• Sponsor nominal purchase price may cause dilution

  “The nominal purchase price paid by our sponsor for the founder shares may result in significant dilution to the implied value of your public shares upon the consummation of our initial business combination, and our sponsor is likely to make a substantial profit on its investment in us in the event we consummate an initial business combination, even if the business combination causes the trading price of our ordinary shares to materially decline.”

• Must consummate business combination within 24 months

  “If we have not consummated an initial business combination within 24 months from the closing of this offering, or such earlier liquidation date as our board of directors may approve, which we refer to as the “completion window,” we will redeem 100% of the public shares for cash, subject to applicable law and certain conditions as described herein.”

• Investors lack protections of Rule 419 blank check offerings

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

• Officer/director fiduciary obligations may compete with company interests

  “As more fully discussed in the section of this prospectus entitled “Management—Conflicts of Interest,” our officers and directors currently have certain relevant fiduciary duties or contractual obligations that may take priority over their duties to us and there may be a conflict of interest in our director's and officer's determination as to how much time to devote to our affairs and to which entity a particular business opportunity is presented.”
