1. 1

   Extension Amendment Proposal

   ManagementBoard: FOR

   Amend the Amended and Restated Memorandum and Articles of Association to extend the deadline to consummate an initial business combination from August 19, 2026 to December 19, 2026.

   More detail

   This proposal asks shareholders to approve a special resolution to amend the Company’s Articles to extend the deadline to complete an initial business combination from August 19, 2026 to December 19, 2026. Management frames the change as necessary because the board and deal parties need additional time to finalize the registration statement and proxy statement for the Proposed Business Combination with Parataxis; without the Extension, the Company would be required by its Articles to liquidate if no qualifying business combination is consummated by August 19, 2026. The extension triggers an immediate redemption offer to public shareholders (the Election), which permits holders to redeem all or a portion of their public shares for a pro rata portion of the Trust Account; management highlights that redemptions will reduce the Trust Account and could impair the Company’s ability to close the Proposed Business Combination. The board conditions implementation of the Extension on approval of the Redemption Limitation Amendment (which would permit redemptions even if net tangible assets fall below $5,000,001), so the two amendments are interdependent and must both be approved to effect the Extension. Approval requires a two‑thirds affirmative vote of shares present and entitled to vote, and founder shares will be voted in favor by Sponsor and initial shareholders, which may materially affect the outcome given Sponsor’s ~21.4% stake. The board recommends a "FOR" vote, concluding the Extension is in the best interests of the Company and its shareholders because it preserves the opportunity to complete the Proposed Business Combination rather than force liquidation. Key risks include the reduction of Trust Account cash through redemptions (which could leave insufficient funds to satisfy deal closing conditions), potential NYSE delisting risk if redemptions materially reduce public float, and the possibility that, even after extension, a business combination may not be consummated. Sophisticated evaluators should weigh the commercial merits of the Proposed Business Combination and the probability of obtaining additional financing or waivers of closing conditions against the dilution of remaining cash in the Trust Account and the interests of Sponsor and insiders who benefit if a deal closes.

2. 2

   Redemption Limitation Amendment Proposal

   ManagementBoard: FOR

   Amend the Articles to remove the limitation that the Company may not redeem public Class A ordinary shares to the extent such redemptions would cause the Company’s net tangible assets to be less than $5,000,001, thereby permitting redemptions irrespective of that threshold.

   More detail

   This proposal would amend several Articles of the Company’s Articles of Association to eliminate the existing Redemption Limitation that prevents redemptions of public shares if those redemptions would cause net tangible assets to fall below $5,000,001. Management presents this amendment as a companion to the Extension — without eliminating the limitation, substantial redemptions in connection with the Extension could make the Extension impossible to implement even if shareholders otherwise approve it. The change would allow the Company to withdraw and deliver to redeeming public shareholders their pro rata portion of the Trust Account (the Withdrawal Amount) even if doing so would reduce net tangible assets below the $5,000,001 threshold, thereby enabling the board to proceed with the Extension and preserve the opportunity to complete the Proposed Business Combination. The amendment reduces a technical impediment to implementing an Extension but shifts risk to remaining public shareholders and to the Company’s liquidity and listing profile because larger redemptions could leave little cash in the Trust Account to satisfy deal closing conditions or NYSE listing requirements. Approval also requires a two‑thirds affirmative vote, and Sponsor and insiders intend to vote in favor, which increases the likelihood of passage but also raises conflict-of-interest considerations given Sponsor’s interests in a completed business combination. Management recommends a "FOR" vote because the Redemption Limitation Amendment is a condition to allowing the Extension to be effected if redemptions otherwise would make the Extension infeasible. Analysts should consider the interplay between likely redemption levels, the anticipated post‑withdrawal cash remaining in the Trust Account, the deal’s required closing cash, potential additional financing or sponsor contributions, and the dilution or market-impact consequences of a materially diminished public float.

3. 3

   Adjournment Proposal

   ManagementBoard: FOR

   Approve adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, to permit further solicitation and vote of proxies if there are insufficient votes to approve the Extension Amendment Proposal or the Redemption Limitation Amendment Proposal or where the board determines it is otherwise necessary.

   More detail

   The Adjournment Proposal seeks shareholder authorization for the board to adjourn the Extraordinary General Meeting to one or more later dates if there are insufficient votes to approve the Extension Amendment or the Redemption Limitation Amendment or if the board otherwise deems adjournment necessary. This is a tactical, procedural measure: if presented and approved, it allows additional time for solicitation of votes and for shareholders to consider supplemental information, but the adjournment cannot extend the meeting beyond August 19, 2026. Approval requires a simple majority of votes present and entitled to vote. Management ties the proposal to the implementation pathway for the Extension and Redemption Limitation amendments — without the ability to adjourn, the meeting could fail to reach the necessary thresholds and the Company would be forced to abandon the amendments and proceed to wind up if a business combination is not completed by the deadline. The board recommends a "FOR" vote to preserve flexibility to continue the solicitation and potentially obtain the supermajority needed for the companion proposals. From an analytical perspective, adjournment increases the time window in which public shareholders may tender redemption elections (which could further reduce Trust Account cash) and provides an opportunity for Sponsor and other insiders to influence outcomes through additional outreach; conversely, it also affords public shareholders more time to assess the Proposed Business Combination and to decide whether to redeem or to support the amendments. Evaluators should weigh the procedural benefits of flexibility against the economic and timing risks associated with further redemptions and any potential adverse market or listing consequences.
