SPAC Registered Offering Prospectus Summary, Identify and Evaluate Potential Business Combination Candidates, Manner [Text Block]

Business Combination Criteria

Consistent with our business strategy, we have identified the following general criteria that we believe are important in evaluating prospective target businesses. We will use these criteria in evaluating initial business combination opportunities, but we may decide to enter into our initial business combination with a target business that does not meet these criteria. We expect that no individual criterion will entirely determine a decision to pursue a particular opportunity. We intend to seek a business combination with a business that we believe:

●

Is fundamentally sound and can unlock and enhance shareholder value through a combination with us, thereby offering attractive risk- adjusted returns for our shareholders;

●

Is at an inflection point, such as requiring additional management expertise, and able to accelerate growth and financial performance through differentiated business models and the addition of our operational, financial, transactional and legal expertise and networks;

●

Is in need of a flexible, creative or opportunistic structure where we can deliver additional value;

●

Has a strong, experienced management team, or provides a platform to assemble an effective management team with a track record of driving growth and profitability;

●

Can benefit from being a publicly traded company, with access to broader capital markets, to achieve the business’ growth strategy;

●

Is poised to grow both organically through the application of technology, as well as inorganically, through bolt-on or transformational acquisitions;

●

Has a leading or niche market position and demonstrates advantages when compared to competitors, which may help to create barriers to entry against new competitors;

●

Exhibits unrecognized value or other characteristics that we believe can be enhanced based on our analysis and due diligence review; and

●

Has a strong, experienced management team with a proven track record of driving revenue growth, enhancing profitability and creating value for their shareholders.

We anticipate offering the following benefits to our business combination partner:

●

Partnership with our management team members who have extensive and proven experience in operating, leading, advising and investing in market leading companies;

●

Access to our deep and broad networks, insights and operational, financial, transactional, and legal and regulatory expertise;

●

Increased company profile and improved credibility with investors, customers, suppliers and other key stakeholders;

●

Higher level of engagement with core, relevant, fundamental investors as anchor shareholders than what a traditional IPO bookbuilding process offers;

●

Expedited path to a public listing with flexible structuring;

●

Ongoing access to public capital markets;

●

Listed public currency for future acquisitions and growth;

●

Ability for management team to retain control and focus on growing the business; and

●

Opportunity to motivate and retain employees using stock-based compensation.

These criteria are not intended to be exhaustive. Any evaluation relating to the merits of a particular initial business combination may be based, to the extent relevant, on these general criteria as well as other considerations and factors that our management team and advisors may deem relevant. In the event that we decide to enter into our initial business combination with a target business that does not meet the above criteria and guidelines, we will disclose that the target business does not meet the above criteria in our shareholder communications related to our initial business combination, which, as discussed in this prospectus, would be in the form of proxy solicitation materials or tender offer documents that we would file with the SEC.

De-SPAC Consummation Timeframe, Limitations on Extensions [Text Block]

There is no limit on the number of extensions that we may seek; however, we do not expect that it will be necessary to extend the time period to consummate our initial business combination beyond 36 months from the closing of this offering.

(1)

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of our initial business combination, or earlier at the option of the holder, on a one-for-one basis, subject to the adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities (as described herein), are issued or deemed issued in excess of the amounts issued in this offering and related to the closing of our initial business combination, the ratio at which the Class B ordinary shares will convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the issued and outstanding Class B ordinary shares agree to waive such anti-dilution adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an as-converted basis, 25% of the sum of (i) the aggregate of our issued and outstanding founder shares, private placement shares and public shares after this offering and the private placement, plus (ii) all Class A ordinary shares and equity-linked securities issued or deemed issued, in connection with the closing of the initial business combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial business combination and any private placement-equivalent units issued to our sponsor or any of its affiliates or to our officers or directors upon conversion of working capital loans) minus (iii) any redemptions of Class A ordinary shares by public shareholders in connection with an initial business combination; provided that such conversion of founder shares will never occur on a less than one-for-one basis. The anti-dilution provisions in our Class B ordinary shares may result in material dilution to the public shareholders.

(2)

Certain non-managing sponsor investors have committed, pursuant to written agreements, to purchase, indirectly through the purchase of non-managing sponsor membership interests, an aggregate of [______] private placement units at a price of $10.00 per unit ($[_________] in the aggregate), which price includes the par value of $0.0001 per restricted Class A share, in a private placement that will close simultaneously with the closing of this offering.

(3)

SPAC, Securities Offered, Redemption Rights [Text Block]

Manner of conducting redemptionsWe will provide our public shareholders with the opportunity to redeem, regardless of whether they abstain, vote for, or against, the initial business combination, all or a portion of their public shares upon the completion of our initial business combination either (1) in connection with a general meeting called to approve the business combination or (2) without a shareholder vote by means of a tender offer. The decision as to whether we will seek shareholder approval of a proposed business combination or conduct a tender offer will be made by us, solely in our discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require us to seek shareholder approval under applicable law or stock exchange listing requirement. Asset acquisitions and share purchases would not typically require shareholder approval while direct mergers with our company where we do not survive and any transactions where we issue more than 20% of our issued and outstanding ordinary shares or seek to amend our amended and restated memorandum and articles of association would require shareholder approval. We currently intend to conduct redemptions in connection with a shareholder vote unless shareholder approval is not required by applicable law or stock exchange rule or we choose to conduct redemptions pursuant to the tender offer rules of the SEC for business or other reasons.

SPAC Additional Financing Plans, Impact on Security Holders [Text Block]

Moreover, we may need to obtain additional financing either to consummate our initial business combination or because we become obligated to redeem a significant number of our public shares upon consummation of our initial business combination, in which case we may issue additional securities or incur debt in connection with such business combination. Subject to compliance with applicable securities laws, we would only consummate such financing simultaneously with the consummation of our initial business combination. Following our initial business combination, if cash on hand is insufficient, we may need to obtain additional financing in order to meet our obligations.
