The information set forth in or incorporated by reference into Items 4, 5 and 6 of this Schedule 13D is hereby incorporated by reference in its entirety into this Item 3.

Item 4. Purpose of Transaction

Founder Shares

On June 19, 2021, the Sponsor paid $25,000 to cover certain of Issuer’s offering and formation costs in exchange for 2,875,000 Class B ordinary shares, par value $0.0001 per share of the Issuer (the “Class B ordinary shares” or the “Founder Shares”). On November 29, 2023, the Sponsor transferred 30,000 Founder Shares to each of the Issuer’s nominated independent directors, Mark McKenna and John Schmid, and to Issuer’s advisor, Andrew Phillips. On February 1, 2024 and February 8, 2024, Issuer effected a share capitalization with respect to the Company’s Class B ordinary shares of 1,437,500 and 287,500 Founder Shares, resulting in the Sponsor holding an aggregate of 4,510,000 Founder Shares. The Founder Shares included an aggregate of up to 600,000 Class B ordinary shares that were subject to forfeiture to the extent that the underwriters’ over-allotment option in connection with the Issuer’s initial public offering (the “IPO”) was not exercised in full, so that the Sponsor would own, on an as-converted basis, approximately 20% of the Issuer’s issued and outstanding shares after the IPO (excluding any public shares purchased by the Sponsor in the IPO and excluding the Private Placement Shares). On February 8, 2024, the underwriter of the IPO exercised its over-allotment option in full and, accordingly, the Founder Shares are no longer subject to forfeiture. The Founder Shares will automatically convert into Class A ordinary shares at the time of the Issuer’s initial business combination (the “Business Combination”) and may be converted at any time prior to the Business Combination, at the option of the holder, on a one-for-one basis, subject to adjustment pursuant to certain anti-dilution rights.

Private Placement Shares

Simultaneously with the closing of the IPO, on February 13, 2024, pursuant to a Private Placement Class A Ordinary Shares Purchase Agreement (the “Private Placement Shares Purchase Agreement”), the Issuer completed the private sale of 509,000 Class A ordinary shares (the “Private Placement Shares”) at a purchase price of $10.00 per Private Placement Share, to the Sponsor, generating gross proceeds to the Issuer of $5,090,000. The Private Placement Shares are identical to the Class A ordinary shares sold in the IPO, except that, so long as they are held by the Sponsor and its permitted transferees: (i) they may not, subject to certain limited exceptions, be transferred, assigned or sold until 30 days after the completion of a Business Combination, (ii) they are entitled to registration rights and (iii) they may not be submitted for redemptions and are not entitled to redemption rights in connection with the completion of a Business Combination or an earlier redemption in connection with shareholder votes to amend the Issuer’s amended and restated memorandum and articles of association (the “charter”). For additional information, please see “Letter Agreement” below in this section.

The foregoing description of the Private Placement Shares Purchase Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the agreement, which is attached as an exhibit hereto and incorporated herein by reference.

Insider Public Shares

Fund III, Cormorant Private Healthcare Fund V, LP, a Delaware limited partnership (“Fund V”), and Cormorant Global Healthcare Master Fund LP, a Cayman Islands limited partnership (“Master Fund”, and together with Fund III and Fund V, the “Cormorant Funds”) participated in the Issuer’s IPO, which closed on February 13, 2024, and acquired 1,427,040, 903,600 and 69,360 Class A ordinary shares, respectively at $10.00 per share (each and collectively, the “Insider Public Shares”). For additional information regarding the redemption, voting and transfer restrictions to the Insider Public Shares, please see “Letter Agreement” below in this section.

Letter Agreement

Sponsor, the Issuer’s officers, directors and advisor, including Bihua Chen, and the Issuer entered into a letter agreement dated February 8, 2024 (the “Letter Agreement”), pursuant to which they agreed to certain voting, lock-up, and redemption rights provisions described in more detail below.

Redemption Rights Waiver

Pursuant to the Letter Agreement, Sponsor and Ms. Chen have agreed to (i) waive their redemption rights with respect to their Founder Shares, Private Placement Shares, Insider Public Shares and any other public shares they may acquire during or after the IPO in connection with the completion of the Business Combination, (ii) waive their redemption rights with respect to their Founder Shares, Private Placement Shares, Insider Public Shares and any public shares they may acquire during or after the IPO in connection with a shareholder vote to approve an amendment to the charter (A) to modify the substance or timing of the Issuer’s obligation to allow redemption in connection with the Business Combination or to redeem 100% of the Issuer’s public shares if the Issuer does not complete the Business Combination within the Issuer’s completion window or (B)  with respect to any other material provisions relating to shareholders’ rights or pre-Business Combination activity, (iii) waive their rights to liquidating distributions from the trust account with respect to their Founder Shares and Private Placement Shares if the Issuer fails to complete the Business Combination within the Issuer’s completion window, although Sponsor and Ms. Chen will be entitled to liquidating distributions from the trust account with respect to the Insider Public Shares or any public shares they hold if the Issuer fails to complete the Business Combination within the prescribed time frame and to liquidating distributions from assets outside the trust account, and (iv) not sell any of the Founder Shares, Private Placement Shares, the Insider Public Shares or any public shares owned by them to the Issuer in the tender offer undertaken by the Issuer if the Company seeks to consummate a Business Combination by engaging in a tender offer.

Voting Agreement

Further, pursuant to the Letter Agreement, Sponsor and Ms. Chen have agreed to vote any of their Founder Shares, Private Placement Shares, Insider Public Shares, as applicable or any public shares purchased during or after the IPO (including in open market and privately-negotiated transactions) in favor of a Business Combination. If the Issuer submits the Business Combination to its public shareholders for a vote, the Issuer will complete the Business Combination only if it is approved by an ordinary resolution under Cayman Islands law, which requires the affirmative vote of at least a majority of the votes cast by the shareholders of the issued shares present in person or represented by proxy and entitled to vote on such matter at a general meeting of the Issuer.

Lock-up Agreement

Further, pursuant to the Letter Agreement, Sponsor and Ms. Chen have agreed that the Founder Shares are not transferable except to certain permitted transferees until the earlier of (A) one year after the completion of the Issuer’s Business Combination and (B) subsequent to the Business Combination, (x) if the closing price of the Class A Ordinary Shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Issuer’s Business Combination or (y) the date on which the Issuer consummates a transaction which results in all of its public shareholders having the right to exchange their Class A ordinary shares for cash, securities, or other property. The Sponsor and Ms. Chen have also agreed that the Private Placement Shares are not transferrable except to certain permitted transferees until 30 days after the completion of a Business Combination. Additionally, the Sponsor and Ms. Chen have agreed that they will not, without the prior consent of the IPO underwriter, transfer, enter into an arrangement to transfer or publicly announce an intent to transfer the Founder Shares, Private Placement Shares, Insider Public Shares, or any public shares they hold, except to certain permitted transferees, commencing on the effective date of the underwriting agreement entered in connection with the IPO and ending 180 days after such date.

The foregoing description of the Letter Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the agreement, which is attached as an exhibit hereto and incorporated herein by reference.

Registration Rights Agreement

In connection with the closing of the IPO, the Issuer entered into a registration rights agreement (the “Registration Rights Agreement”) with Sponsor, pursuant to which Sponsor is entitled to make up to three demands, excluding short form demands, that the Issuer register Founder Shares, Private Placement Shares, any ordinary shares held or acquired by the Sponsor prior to the consummation of the Business Combination, and any securities that may be issued as part of working capital loans. In addition, Sponsor has certain “piggy-back” registration rights with respect to registration statements filed subsequent to the Business Combination and rights to require the Issuer to register for resale such securities pursuant to Rule 415 under the Securities Act.

The foregoing description of the Registration Rights Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the agreement, which is attached as an exhibit hereto and incorporated herein by reference.

Administrative Services Agreement

Sponsor and the Issuer entered into an Administrative Services and Indemnification Agreement dated February 8, 2024 (the “Administrative Services Agreement”), pursuant to which the Issuer agreed to pay Sponsor $6,458 per month for office space, utilities, administrative services and remote support services provided to members of the Issuer’s management team. The Issuer will cease paying these monthly fees upon completion of a Business Combination or Issuer’s liquidation. Additionally, the Issuer will indemnify the Sponsor, members and managers and representatives of the Sponsor, including Ms. Chen (collectively, “Sponsor Indemnitees”) from any claims arising out of or relating to the IPO or the Issuer’s operations or conduct of the Issuer’s business or any claim against any Sponsor Indemnitees alleging any expressed or implied management or endorsement by Sponsor Indemnitees of any of the Issuer’s activities or any express or implied association between Sponsor Indemnitees, on the one hand, and the Issuer or any of its other affiliates, on the other hand. The Administrative Services Agreement provides that the Sponsor Indemnitees cannot access or seek recourse against the funds held in the Issuer’s trust account established for the benefit of the Issuer’s public shareholders.

Indemnification Agreement

Bihua Chen and Issuer entered into an Indemnification Agreement dated February 8, 2024 (the “Indemnification Agreement”), pursuant to which the Issuer will indemnify Ms. Chen, who serves as a director and an officer of the Issuer, to the fullest extent permitted by applicable law, providing that Ms. Chen has agreed to waive any right, title, interest or claim of any kind in or to any monies in the trust account and to not seek recourse against the trust account for any reason whatsoever.

Promissory Note

On June 19, 2021, as amended in October 2023, the Issuer issued an unsecured promissory note (the “Promissory Note”) to the Sponsor, pursuant to which the Issuer may borrow up to an aggregate principal amount of $300,000. The Promissory Note is non-interest bearing and payable on the earlier of (i) June 30, 2024 or (ii) the completion of the IPO. As of the closing of the IPO, the Issuer had $70,095 outstanding under the Promissory Note, which is due on demand.

Related Party Loans

In order to finance transaction costs in connection with an intended Business Combination, Reporting Persons may, but are not obligated to, loan the Issuer funds as may be required on a non-interest basis. If the Issuer completes a Business Combination, it would repay such loaned amounts. In the event that the Business Combination does not close, Issuer may use a portion of the working capital held outside the trust account to repay such loaned amounts but no proceeds from its trust account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into private placement shares of the post business combination entity at a price of $10.00 per share at the option of the lender.

Indication of Interest

The Cormorant Funds have also indicated an interest to purchase an aggregate of $35,000,000 of the Issuer’s Class A ordinary shares in a private placement that would occur concurrently with the consummation of the Business Combination. However, because indications of interest are not binding agreements or commitments to purchase, the Cormorant Funds may determine not to purchase any such shares, or to purchase fewer shares than they have indicated an interest in purchasing. The Issuer is not under any obligation to sell any such shares. Such investment would be made on terms and conditions determined at the time of the Business Combination.

General

The Reporting Persons acquired the securities described in this Schedule 13D for investment purposes and intend to review their investments in the Issuer on a continuing basis. Subject to the terms of the Letter Agreement, any actions the Reporting Persons might undertake may be made at any time and from time to time without prior notice and will be dependent upon the Reporting Persons’ review of numerous factors, including, but not limited to: an ongoing evaluation of the Issuer’s business, financial condition, operations and prospects; price levels of the Issuer’s securities; general market, industry and economic conditions; the relative attractiveness of alternative business and investment opportunities; and other future developments.

Subject to the terms of the Letter Agreement and applicable law, the Reporting Persons may acquire additional securities of the Issuer, or retain or sell all or a portion of the securities then held, in the open market or in privately negotiated transactions, including pursuant to registered transactions pursuant to the Registration Rights Agreement. In addition, Ms. Chen is the Chief Executive Officer of the Issuer and is the chairperson of the board of directors of the Issuer. As such, Ms. Chen takes and will continue to take, an active role in the Issuer’s management and strategic direction, including activities of the sort described in clauses (a) through (j) of Item 4 of Schedule 13D. In light of her responsibilities to the Issuer, Ms. Chen does not anticipate making any disclosures in connection with her participation in the transactions and activities of the Issuer separate and apart from relevant disclosures by the Issuer, unless otherwise required by Schedule 13D. The other Reporting Persons and their representatives to the Issuer’s board of directors may also engage in discussions with management, the Issuer’s board of directors, and securityholders of the Issuer and other relevant parties or encourage, cause or seek to cause the Issuer or such persons to consider or explore extraordinary corporate transactions, such as: a merger, reorganization or other transaction that could result in the de-listing or de-registration of the Ordinary Shares; sales or acquisitions of assets or businesses; changes to the capitalization or dividend policy of the Issuer; or other material changes to the Issuer’s business or corporate structure, including changes in management or the composition of the Board. There can be no assurance, however, that any Reporting Person will propose such a transaction or that any such transaction would be successfully implemented.

Other than as described above, the Reporting Persons do not currently have any plans or proposals that relate to, or would result in, any of the matters listed in Items 4(a)–(j) of Schedule 13D, although, depending on the factors discussed herein, the Reporting Persons may change their purpose or formulate different plans or proposals with respect thereto at any time.
