 shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from exercising redemption rights with respect to more than an aggregate of 15% of the shares sold in this offering without our prior consent. However, we would not restrict our shareholders’ ability to vote all of their shares (including all shares held by those shareholders that hold more than 15% of the shares sold in this offering) for or against our initial business combination or to abstain from voting. See “Summary — The Offering — Limitation on redemption rights of shareholders holding more than 15% of the shares sold in this offering if we hold a shareholder vote” for further discussion on certain limitations on redemption rights. If we are unable to complete our initial business combination within 24 months from the closing of this offering, the period of time we have to complete an initial business combination can be extended without shareholder approval by up to an additional six months (for a total of up to 30 months to complete an initial business combination from the closing of this offering), subject to certain conditions. We refer to the time period we have to complete an initial business combination, as it may be extended as described above, as the “completion window.” If our completion window is extended as described above, our shareholders will not be entitled to vote on or redeem their shares in connection with any such extension. If we anticipate that we may not be able to consummate our initial business combination within such period, we may seek shareholder approval of amendments to our amended and restated memorandum and articles of association for any extension beyond 30months at a general meeting called for such purpose. If we have not completed our initial business combination within the completion window or by such earlier liquidation date as our board of directors may approve, we will redeem 100% of the issued and outstanding public shares at a per -shareprice, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest (less taxes payable (other than excise or similar taxes) and up to $100,000 of interest to pay

dissolution expenses), divided by the number of then issued and outstanding public shares, subject to applicable law and as further described herein. See “Summary — The Offering — Redemption of public shares and distribution and liquidation if no initial business combination” for more information.
