Key risk factors
-
Public shareholder redemption risk
“The ability of our public shareholders to exercise redemption rights with respect to a large number of our shares and the amount of the deferred underwriting compensation may not allow us to complete the most desirable business combination or optimize our capital structure, and may substantially dilute your investment in us”
-
Dilution from additional share issuances
“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. We may also issue Class A ordinary shares upon the conversion of the Class B ordinary shares at a ratio greater than one-to-one at the time of our initial business combination as a result of the anti-dilution provisions contained therein. Any such issuances would dilute the interest of our shareholders and likely present other risks”
-
Immediate dilution from founder share purchase price
“Our initial shareholders paid an aggregate of $25,000, or approximately $0.002 per founder share and, accordingly, you will experience immediate and substantial dilution from the purchase of our Class A ordinary shares”
-
Issuance of shares at below-market prices
“We may issue shares to investors in connection with our initial business combination at a price which is less than $10.00 or the prevailing market price of our shares at that time, which could materially dilute the interests of our existing shareholders and add costs.”
