Redemption Rights for Public Shareholders in Connection with the Completion of Our Initial Business Combination

We will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares in connection with the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account calculated as of two business days prior to the consummation of the initial business combination, including interest earned on the funds held in the trust account (less taxes paid or payable (other than excise or similar taxes)), divided by the number of then outstanding public shares, subject to the limitations and on the conditions described herein. The amount in the trust account is initially anticipated to be $10.00 per public share. The per share amount we will distribute to investors who properly redeem their shares will not be reduced by the deferred underwriting commissions we will pay to the underwriter. Our sponsor, officers and directors have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to their founder shares, private placement shares and any public shares they may hold in connection with the completion of our initial business combination.

Limitation on Redemptions

Our proposed initial business combination may impose a minimum cash requirement for (i) cash consideration to be paid to the target or its owners, (ii) cash for working capital or other general corporate purposes or (iii) the retention of cash to satisfy other conditions. In the event the aggregate cash consideration we would be required to pay for all Class A ordinary shares that are validly submitted for redemption plus any amount required to satisfy cash

conditions pursuant to the terms of the proposed initial business combination exceed the aggregate amount of cash available to us, we will not complete the initial business combination or redeem any shares, and all Class A ordinary shares submitted for redemption will be returned to the holders thereof. We may, however, raise funds through the issuance of equity-linked securities or through loans, advances or other indebtedness in connection with our initial business combination, including pursuant to forward purchase agreements or backstop arrangements we may enter into following consummation of this offering, in order to, among other reasons, satisfy such net tangible assets or minimum cash requirements.

Manner of Conducting Redemptions

We will provide our public shareholders with the opportunity to redeem all or a portion of their Class A ordinary shares in connection with the completion of our initial business combination either (i) in connection with a general meeting called to approve the business combination or (ii) 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 or whether we were deemed to be a foreign private issuer (which would require a tender offer rather than seeking shareholder approval under SEC rules), as described above under the heading “— Shareholders May Not Have the Ability to Approve Our Initial Business Combination.” 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 (excluding the private placement shares) or seek to amend our articles would require shareholder approval. So long as we obtain and maintain a listing for our securities on Nasdaq, we will be required to comply with Nasdaq’s shareholder approval rules.

The requirement that we provide our public shareholders with the opportunity to redeem their public shares by one of the two methods listed above will be contained in provisions of our articles and will apply whether or not we maintain our registration under the Exchange Act or our listing on Nasdaq. Such provisions may be amended if approved by special resolution under Cayman Islands law, which requires the affirmative vote of at least two-thirds of the votes cast by the shareholders of the issued shares present in person or represented by proxy and entitled to vote thereon on such matter at a general meeting of the company, so long as we offer redemption in connection with such amendment.

If we provide our public shareholders with the opportunity to redeem their public shares in connection with a general meeting, we will, pursuant to our articles:

• conduct the redemptions in conjunction with a proxy solicitation pursuant to Regulation 14A of the Exchange Act, which regulates the solicitation of proxies, and not pursuant to the tender offer rules, and

• file proxy materials with the SEC.

In the event that we seek shareholder approval of our initial business combination, we will distribute proxy materials and, in connection therewith, provide our public shareholders with the redemption rights described above in connection with the completion of the initial business combination.

SPAC, Adjusted Net Tangible Book Value Per Share with Sources of Dilution [Table Text Block]

At November 21, 2025, our net tangible book deficit was $89,359, or approximately $0.02 per ordinary share. The following table illustrates what the Adjusted NTBVPS at November 21, 2025, would have been to the public shareholders on a pro forma basis to give effect to this offering and the issuance of the private placement shares, assuming no exercise of the over-allotment option and exercise of the over-allotment option in full:

(1) Expenses applied against gross proceeds include offering expenses of approximately $875,000 (not including $625,000 for director and officer liability insurance premiums to be paid upon closing of this offering, which amount is not an offering expense to be capitalized) and underwriting commissions of $1,250,000. See “Use of Proceeds.”

(2) Represents the value of 45-day over-allotment option from the date of this offering granted to the underwriters to purchase an aggregate of up to 1,875,000 additional Class A ordinary shares at the initial public offering price less the underwriting commissions. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the shares subject to redemption and will be accounted for as a liability pursuant to ASC 480 if not fully exercised at the time of the initial public offering. The table above assumes that the option has either been fully exercised or has expired with no exercise to purchase additional shares, thus the value of over-allotment liability in both scenario is $0.

(3) If we seek shareholder approval of our initial business combination and we do not conduct redemptions in connection with our initial business combination pursuant to the tender offer rules, our sponsor, initial shareholders, directors, executive officers, advisors or their affiliates may purchase shares in privately negotiated transactions or in the open market either prior to or following the completion of our initial business combination. In the event of any such purchases of our shares prior to the completion of our initial business combination, the number of ordinary shares subject to redemption will be reduced by the amount of any such purchases, increasing the pro forma NTBV. See “Proposed Business — Effecting Our Initial Business Combination — Permitted Purchases of Our Securities.”

(4) For purposes of presenting the maximum redemption scenario, we have reduced our pro forma net tangible book value after this offering (assuming no exercise of the underwriters’ option to purchase additional shares) by $125,000,000 because holders of up to approximately 100% of our public shares may redeem their shares for a pro rata share of the aggregate amount then on deposit in the trust account at a per share redemption price equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account less taxes paid or payable (other than excise or similar taxes), divided by the number of then issued and outstanding public shares, subject to the limitations and on the conditions described herein.
