NOTICE OF EXTRAORDINARY GENERAL MEETING
IN LIEU OF THE 2023 ANNUAL GENERAL MEETING OF SHAREHOLDERS

TO BE HELD ON SEPTEMBER [ ], 2023

TO THE SHAREHOLDERS OF BLOCKCHAIN COINVESTORS ACQUISITION CORP. I:

You are cordially invited to attend the extraordinary general meeting in lieu of the 2023 annual general meeting of shareholders (the “Extraordinary General Meeting”) of Blockchain Coinvestors Acquisition Corp. I (“BCSA”), to be held at [ ] [a.m./p.m.] Eastern Time, on September [ ], 2023. You will be able to attend the Extraordinary General Meeting online, vote, and submit your questions during the Extraordinary General Meeting by visiting https://www.cstproxy.com/blockchaincac1/sm2023. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the physical location of the Extraordinary General Meeting at the offices of Perkins Coie LLP located at 1120 NW Couch Street, 10th Floor, Portland, OR 97209, United States of America.

The Extraordinary General Meeting is being held to consider and vote upon the following proposals:

1. As a special resolution, to amend BCSA’s Amended and Restated Memorandum and Articles of Association, as amended (the “Governing Documents”), in the form set forth in Annex A to the accompanying proxy statement (the “Extension Amendment”), to extend the date by which BCSA must consummate a business combination (as defined below) (the “Extension”) from November 15, 2023 to May 15, 2024 or such earlier date as may be determined by the Board in its sole discretion (the “Extended Date”) (the “Extension Amendment Proposal”).

2. As a special resolution, to amend the Governing Documents in the form set forth in Annex B to the accompanying proxy statement (the “Redemption Limitation Amendment”) to eliminate the limitation that BCSA may not redeem public shares in an amount that would cause BCSA’s net tangible assets to be less than $5,000,001 (the “Redemption Limitation”) either immediately prior to or upon consummation of a business combination (the “Redemption Limitation Amendment Proposal”).

3. As a special resolution, to amend the Governing Documents in the form set forth in Annex C to the accompanying proxy statement (the “Founder Share Amendment” and together with the Extension Amendment and the Redemption Limitation Amendment, the “Charter Amendments”) to permit for the issuance of Class A ordinary shares, par value $0.0001 per share (the “public shares” or “Class A ordinary shares”) to holders of Class B ordinary shares, par value $0.00009 per share (the “founder shares” or “Class B ordinary shares” and together with the public shares, the “ordinary shares”), upon the exercise of the right of a holder of BCSA’s Class B ordinary shares to convert such holder’s Class B ordinary shares into Class A ordinary shares on a one-for-one basis at any time and from time to time prior to the closing of an initial business combination at the election of the holder (the “Founder Share Amendment Proposal,” and together with the Extension Amendment Proposal and Redemption Limitation Amendment Proposal, the “Articles Amendment Proposals”).

4. As an ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, either (x) to permit further solicitation and vote of proxies in the event that there are insufficient votes to approve any of the Articles Amendment Proposals or if BCSA determines that it is otherwise necessary or (y) if the board of directors (the “Board”) determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals (the “Adjournment Proposal”).

Table of Contents

Each of the Extension Amendment Proposal, the Redemption Limitation Amendment Proposal, the Founder Share Amendment Proposal and the Adjournment Proposal is more fully described in the accompanying proxy statement. Approval of each of the Redemption Limitation Amendment Proposal and Founder Share Amendment Proposal is cross-conditioned on the approval of the Extension Amendment Proposal.

You will be able to attend and participate in the Extraordinary General Meeting online by visiting https://www.cstproxy.com/blockchaincac1/sm2023. Please see “Questions and Answers about the Extraordinary General Meeting — How do I attend the Extraordinary General Meeting?” in the accompanying proxy statement for more information.

THE BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS A VOTE “FOR” THE EXTENSION AMENDMENT PROPOSAL, THE REDEMPTION LIMITATION AMENDMENT PROPOSAL. THE FOUNDER SHARE AMENDMENT PROPOSAL AND, IF PRESENTED, THE ADJOURNMENT PROPOSAL.

On November 10, 2022, BCSA entered into a Business Combination Agreement (as it may be amended, supplemented or otherwise modified from time to time, the “Business Combination Agreement”), with BCSA Merger Sub, Inc., a Delaware corporation (“Merger Sub”), and Qenta Inc., a Delaware corporation (“Qenta”). The Business Combination Agreement provides for, among other things, the following transactions: (i) BCSA will become a Delaware corporation (the “Domestication”) and, in connection with the Domestication, (A) BCSA’s name will be changed to “Qenta Inc.” (“New Qenta”) and (B) each of the outstanding Class A ordinary shares and outstanding Class B ordinary shares, will become one share of common stock of New Qenta (the “New Qenta Common Stock”); and (ii) following the Domestication, Merger Sub will merge with and into Qenta, with Qenta as the surviving company in the merger and continuing as a wholly-owned subsidiary of New Qenta (the “Merger,” and together with the Domestication and the other transactions contemplated by the Business Combination Agreement, the “Proposed Business Combination”).

The sole purpose of the Extension Amendment Proposal is to provide BCSA with sufficient time to complete the Proposed Business Combination, or any potential alternative merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination involving BCSA and one or more businesses (a “business combination”). BCSA’s Governing Documents provide that BCSA has until November 15, 2023 (the “Current Outside Date”) to complete a business combination. While BCSA and the other parties to the Business Combination Agreement are working toward satisfaction of the conditions to completion of the Proposed Business Combination, BCSA’s Board currently believes that there may not be sufficient time to complete the U.S. Securities and Exchange Commission (the “SEC”) review process and hold an extraordinary general meeting to obtain shareholder approval of and consummate the Proposed Business Combination, or any potential alternative initial business combination, by the Current Outside Date. If BCSA were precluded from completing its initial business combination, including the Proposed Business Combination, by the Current Outside Date, BCSA would be forced to liquidate even if its shareholders are otherwise in favor of consummating such business combination. The Board believes that the initial business combination opportunity with Qenta is compelling and has determined that it is in the best interests of BCSA and its shareholders to extend the Current Outside Date to the Extended Date and have BCSA’s shareholders approve the Extension Amendment Proposal.

If the Extension Amendment Proposal is approved, BCSA plans to hold another general meeting prior to the Extended Date in order to seek shareholder approval of the Proposed Business Combination, or any potential alternative initial business combination, and related proposals. For more information regarding the Proposed Business Combination and the Business Combination Agreement, please read BCSA’s Current Report on Form 8-K relating to the Business Combination that was filed with the SEC on November 10, 2022, including the complete text of the Business Combination Agreement filed as an exhibit thereto.

The purpose of the Redemption Limitation Amendment Proposal is to eliminate from the Governing Documents the Redemption Limitation. If the Redemption Limitation Amendment Proposal is not approved and there are significant requests for redemption in connection with approval of the Articles Amendment Proposals such that the Redemption Limitation would be exceeded, the Redemption Limitation may prevent us from being able to proceed with the amendments contemplated by the Articles Amendment Proposals, including the Extension, which may prevent us from consummating an initial business combination within the timeframe prescribed by the Governing Documents. If we fail to consummate an initial business combination within such timeframe, we will be required to liquidate as

Table of Contents

described in the accompanying proxy statement. The Board believes that it is advisable for us to be allowed to effect redemptions and proceed with the Extension or consummate an initial business combination irrespective of the Redemption Limitation.

The purpose of the Founder Share Amendment Proposal is to provide the holders of Class B ordinary shares with the flexibility to assist the Company in meeting the listing requirements of its Class A ordinary shares if necessary or desirable in connection with the Extension and the consummation of an initial business combination. For example, if there are significant requests for redemption such that upon completing the redemptions BCSA no longer satisfies the listing criteria set forth in Nasdaq Listing Rule 5450, the Founder Share Amendment Proposal will provide an avenue for regaining compliance. This flexibility may also assist the Company in retaining investors. Notwithstanding conversion of Class B ordinary shares into Class A ordinary shares, the holders of such converted shares have waived their rights and will not be entitled to receive any monies held in the trust account established by BCSA in connection with its initial public offering (the “trust account”) as a result of its ownership of any Class A ordinary shares.

If the Adjournment Proposal is presented to BCSA’s shareholders because there are insufficient votes to approve one or more of the Articles Amendment Proposals at the Extraordinary General Meeting, the purpose of the Adjournment Proposal is to allow BCSA to adjourn the Extraordinary General Meeting to a later date or dates to permit further solicitation and vote of proxies for such Articles Amendment Proposal(s). The Adjournment Proposal may also be presented if the Board determines that adjournment is otherwise necessary or determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.

The approval of each of the Articles Amendment Proposal, the Redemption Limitation Amendment Proposal and the Founder Share Amendment Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of at least a two-thirds (2/3) majority of the votes cast by the holders of BCSA’s issued Class A ordinary shares and Class B ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter.

As of the date of this proxy statement, BCSA’s sponsor, Blockchain Coinvestors Acquisition Sponsors I LLC (the “Sponsor”), and BCSA’s independent directors hold in aggregate 10,000,000 founder shares. In addition, the Sponsor holds 1,322,000 shares of Class A ordinary shares underlying the 1,322,000 private placement units which the Sponsor purchased in a private placement concurrently with the consummation of the initial public offering (the “IPO”). Accordingly, the shares held by the Sponsor and BCSA’s independent directors (collectively, the “initial shareholders”) represent approximately 76.0% of BCSA’s outstanding ordinary shares.

The Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a simple majority of the votes cast by the holders of the issued ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter.

BCSA’s Board has fixed the close of business on August 29, 2023 as the record date for determining BCSA’s shareholders entitled to receive notice of and vote at the Extraordinary General Meeting and any adjournment thereof. Only holders of record of BCSA’s ordinary shares on that date are entitled to have their votes counted at the Extraordinary General Meeting or any adjournment thereof.

On the record date, there were 4,915,271 Class A ordinary shares issued and outstanding, which includes an aggregate of 1,322,000 private placement shares, and 10,000,000 Class B ordinary shares issued and outstanding, which vote together as a single class with respect to the Articles Amendment Proposals and, if presented, the Adjournment Proposal. BCSA’s warrants do not have voting rights in connection with either the Articles Amendment Proposals or the Adjournment Proposal.

In connection with the Articles Amendment Proposals, if approved by the requisite vote of shareholders, holders of public shares (“public shareholders”) may elect to redeem their public shares for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account as of two business days prior to such approval, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares (the “Election”), subject to certain limitations, regardless of whether such public shareholders vote on the Articles Amendment Proposals. However, a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group”

Table of Contents

(as defined under Section 13(d)(3) of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from seeking redemption rights with respect to more than an aggregate of 15% of the Class A ordinary shares without the prior consent of BCSA. The initial shareholders have agreed to waive their redemption rights with respect to their founder shares and public shares, as applicable, in connection with a shareholder vote to approve certain amendments to BCSA’s Governing Documents, including a vote to approve an extension to the Current Outside Date.

If the Articles Amendment Proposals are approved by the requisite vote of shareholders, the Withdrawal Amount (as defined below) will be withdrawn from the trust account and paid to the redeeming public shareholders with respect to the portion of public shares that were validly redeemed as described above. The remaining public shareholders will retain the opportunity to have their public shares redeemed in conjunction with the consummation of the Proposed Business Combination, or any potential alternative initial business combination, subject to any limitations set forth in the Governing Documents. In addition, the remaining public shareholders will be entitled to have their public shares redeemed for cash if BCSA has not completed a business combination by the Extended Date.

In addition, if the Articles Amendment Proposals are approved, we expect that the Sponsor and BCSA’s independent directors, as the sole holders of Class B ordinary shares, will elect to convert some or all of their Class B ordinary shares to Class A ordinary shares, on a one-for-one basis, in accordance with the Governing Documents (collectively, the “Class B Conversion”). The Class B Conversion would be effected prior to the redemption of any public shares in connection with such approval and could result in up to an additional 10,000,000 Class A ordinary shares outstanding. Notwithstanding the Class B Conversion, the Sponsor and BCSA’s independent directors will not be entitled to receive any funds held in the trust account with respect to any Class A ordinary shares issued to them as a result of the Class B Conversion and no additional amounts will be deposited into the trust account in respect of any such Class A ordinary shares.

BCSA estimates that the per-share price at which the public shares may be redeemed from cash held in the trust account will be approximately $[ ] (which amount includes interest earned on the funds held in the trust account and not previously or yet released to BCSA to pay its taxes), for illustrative purpose, calculated as of August 29, 2023, the record date of the Extraordinary General Meeting. On the record date, the closing price of BCSA’s Class A ordinary shares on The Nasdaq Stock Exchange (“Nasdaq”) was $[ ]. BCSA cannot assure public shareholders that they will be able to sell their public shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

If the Extension Amendment Proposal is not approved, BCSA may again seek to extend the Current Outside Date. If the Extension Amendment Proposal is not approved, the Current Outside Date is not otherwise extended and BCSA does not consummate an initial business combination by the Current Outside Date, in accordance with its Governing Documents, BCSA will (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to BCSA to pay its franchise and income taxes, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any, subject to applicable law); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of BCSA’s remaining shareholders and its board of directors, liquidate and dissolve, subject in each case to BCSA’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable laws. In addition, there will be no redemption rights or liquidating distributions with respect to BCSA’s warrants, including the warrants included in the units sold in the IPO (the “public warrants”), which will expire worthless in the event BCSA winds up, liquidates and dissolves.

Table of Contents

You are not being asked to vote on any proposed business combination at this time. If the Articles Amendment Proposals are approved and you do not elect to redeem your public shares in connection with such approval, you will retain the right to vote on the Proposed Business Combination, or any potential alternative initial business combination, when and if such business combination is submitted to the public shareholders (provided that you are a shareholder on the record date for a meeting to consider such business combination) and the right to redeem your public shares for a pro rata portion of the trust account in the event any proposed business combination is approved and completed or BCSA has not consummated a business combination by the Extended Date.

After careful consideration of all relevant factors, BCSA’s Board has determined that the Extension Amendment Proposal, the Redemption Limitation Amendment Proposal, the Founder Share Amendment Proposal and, if presented, the Adjournment Proposal are advisable and recommends that you vote or give instruction to vote “FOR” each of the Extension Amendment Proposal, the Redemption Limitation Amendment Proposal, the Founder Share Amendment Proposal and, if presented, the Adjournment Proposal.

Enclosed is the proxy statement containing detailed information concerning the Articles Amendment Proposals, the Adjournment Proposal and the Extraordinary General Meeting. Whether or not you plan to attend the Extraordinary General Meeting, BCSA urges you to read this material carefully and vote your shares.

I look forward to seeing you at the Extraordinary General Meeting.

PROXY STATEMENT FOR THE EXTRAORDINARY GENERAL MEETING
IN LIEU OF THE 2023 ANNUAL GENERAL MEETING OF SHAREHOLDERS

TO BE HELD ON SEPTEMBER [ ], 2023

You are cordially invited to attend the extraordinary general meeting in lieu of the 2023 annual general meeting of shareholders (the “Extraordinary General Meeting”) of Blockchain Coinvestors Acquisition Corp. I (“BCSA,” “we,” “us” or “our”), to be held at [ ] [a.m./p.m.] Eastern Time, on September [ ], 2023. You will be able to attend the Extraordinary General Meeting online, vote, and submit your questions during the Extraordinary General Meeting by visiting https://www.cstproxy.com/blockchaincac1/sm2023. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the physical location of the Extraordinary General Meeting at the offices of Perkins Coie LLP located at 1120 NW Couch Street, 10th Floor, Portland, OR 97209, United States of America.

The Extraordinary General Meeting is being held to consider and vote upon the following proposals:

1. As a special resolution, to amend BCSA’s Amended and Restated Memorandum and Articles of Association, as amended (the “Governing Documents”), in the form set forth in Annex A to this proxy statement (the “Extension Amendment”), to extend the date by which BCSA must consummate a business combination (as defined below) (the “Extension”) from November 15, 2023 to May 15, 2024 or such earlier date as may be determined by the Board in its sole discretion (the “Extended Date”) (the “Extension Amendment Proposal”).

2. As a special resolution, to amend the Governing Documents in the form set forth in Annex B to this proxy statement (the “Redemption Limitation Amendment”) to eliminate the limitation that BCSA may not redeem public shares in an amount that would cause BCSA’s net tangible assets to be less than $5,000,001 (the “Redemption Limitation”) either immediately prior to or upon consummation of a business combination (the “Redemption Limitation Amendment Proposal”).

3. As a special resolution, to amend the Governing Documents in the form set forth in Annex C to this proxy statement (the “Founder Share Amendment” and together with the Extension Amendment and the Redemption Limitation Amendment, the “Charter Amendments”) to permit for the issuance of Class A ordinary shares, par value $0.0001 per share (the “public shares” or “Class A ordinary shares”) to holders of Class B ordinary shares, par value $0.00009 per share (the “founder shares” or “Class B ordinary shares” and together with the public shares, the “ordinary shares”), upon the exercise of the right of a holder of BCSA’s Class B ordinary shares to convert such holder’s Class B ordinary shares into Class A ordinary shares on a one-for-one basis at any time and from time to time prior to the closing of an initial business combination at the election of the holder (the “Founder Share Amendment Proposal,” and together with the Extension Amendment Proposal and Redemption Limitation Amendment Proposal, the “Articles Amendment Proposals”).

Table of Contents

The sole purpose of the Extension Amendment Proposal is to provide BCSA with sufficient time to complete the Proposed Business Combination, or any potential alternative merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or similar business combination involving BCSA and one or more businesses (a “business combination”). BCSA’s Governing Documents provide that BCSA has until November 15, 2023 (the “Current Outside Date”) to complete a business combination. While BCSA and the other parties to the Business Combination Agreement are working toward satisfaction of the conditions to completion of the Proposed Business Combination, BCSA’s Board believes that there may not be sufficient time to complete the U.S. Securities and Exchange Commission (the “SEC”) review process and hold an extraordinary general meeting to obtain shareholder approval of and consummate the Proposed Business Combination, or any potential alternative initial business combination, by the Current Outside Date. If BCSA were precluded from completing its initial business combination, including the Proposed Business Combination, by the Current Outside Date, BCSA would be forced to liquidate even if its shareholders are otherwise in favor of consummating such business combination. The Board believes that the initial business combination opportunity with Qenta is compelling and has determined that it is in the best interests of BCSA and its shareholders to extend the Current Outside Date to the Extended Date and have BCSA’s shareholders approve the Extension Amendment Proposal.

Table of Contents

The purpose of the Founder Share Amendment Proposal is to provide the holders of Class B ordinary shares with the flexibility to assist the Company in meeting the listing requirements of its Class A ordinary shares if necessary or desirable in connection with the Extension and the consummation of an initial business combination. For example, if there are significant requests for redemption such that upon completing the redemptions BCSA no longer satisfies the listing criteria set forth in Nasdaq Listing Rule 5450, the Founder Share Amendment Proposal will provide an avenue for regaining compliance. This flexibility may also assist the Company in retaining investors. Notwithstanding conversion of Class B ordinary shares into Class A ordinary shares, the holders of such converted shares have already waived their rights and will not be entitled to receive any monies held in the trust account established by BCSA in connection with its initial public offering (the “trust account”) as a result of its ownership of any Class A ordinary shares.

As of the date of this proxy statement, BCSA’s sponsor, Blockchain Coinvestors Acquisition Sponsors I LLC (the “Sponsor”), and BCSA’s independent directors hold in aggregate 10,000,000 founder shares. In addition, the Sponsor holds 1,322,000 Class A ordinary shares underlying the 1,322,000 private placement units which the Sponsor purchased in a private placement concurrently with the consummation of the initial public offering (the “IPO”). Accordingly, the shares held by the Sponsor and BCSA’s independent directors (collectively, the “initial shareholders”) represent approximately 76.0% of BCSA’s outstanding ordinary shares.

On the record date, there were 4,915,271 Class A ordinary shares issued and outstanding, which includes an aggregate of 1,322,000 private placement shares, and 10,000,000 Class B ordinary shares issued and outstanding, which vote together as a single class with respect to the Articles Amendment Proposals and, if presented, the Adjournment Proposal. BCSA’s warrants do not have voting rights in connection with either the Extension Amendment Proposal or the Adjournment Proposal.

shares without the prior consent of BCSA. The initial shareholders have agreed to waive their redemption rights with respect to their founder shares and public shares, as applicable, in connection with a shareholder vote to approve certain amendments to BCSA’s Governing Documents, including a vote to approve an extension to the Current Outside Date.

The withdrawal of funds from the trust account in connection with the Election will reduce the amount held in the trust account following the Election, and the amount remaining in the trust account after such withdrawal may be only a fraction of the $[ ] million, plus accrued interest (less any funds used to pay taxes) that was in the trust account as of the record date. In such event, BCSA may still seek to obtain additional funds to complete the Business Combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

Table of Contents

The Sponsor has agreed that it will be liable to BCSA if and to the extent any claims by a third party for services rendered or products sold to BCSA, or a prospective target business with which BCSA has entered into a written letter of intent, confidentiality or similar agreement or business combination agreement, reduce the amount of funds in the trust account to below the lesser of (i) $10.20 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account, if less than $10.20 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the trust account (whether or not such waiver is enforceable) nor will it apply to any claims under BCSA’s indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). However, BCSA has not asked the Sponsor to reserve for such indemnification obligations, nor has it independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and believe that the Sponsor’s only assets are securities of BCSA. Therefore, BCSA cannot assure that its Sponsor would be able to satisfy those obligations.

If the Articles Amendment Proposals are approved, such approval will constitute consent for BCSA to (i) remove from the trust account an amount (the “Withdrawal Amount”) equal to the number of public shares properly redeemed multiplied by the per-share price, equal to the aggregate amount then on deposit in the trust account as of two business days prior to such approval, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares and (ii) deliver to the holders of such redeemed public shares their portion of the Withdrawal Amount. The remainder of such funds shall remain in the trust account and be available for use by BCSA to complete the Proposed Business Combination, or any potential alternative initial business combination, on or before the Extended Date. Holders of public shares who do not redeem their public shares now will retain their redemption rights and their ability to vote on such business combination through the Extended Date if the Articles Amendment Proposals are approved.

This proxy statement contains important information about the Extraordinary General Meeting and the proposals to be voted on at the Extraordinary General Meeting. Please read it carefully and vote your shares.

QUESTIONS AND ANSWERS ABOUT THE EXTRAORDINARY GENERAL MEETING

These Questions and Answers are only summaries of the matters they discuss. They do not contain all of the information that may be important to you. You should read carefully the entire proxy statement, including the annex to this proxy statement.

Why am I receiving this proxy statement?

This proxy statement and the enclosed proxy card are being sent to you in connection with the solicitation of proxies by our Board for use at the Extraordinary General Meeting, or at any adjournments or postponements thereof. This proxy statement summarizes the information that you need to make an informed decision on the proposals to be considered at the Extraordinary General Meeting.

BCSA is a blank check company incorporated on June 11, 2021, as a Cayman Islands exempted company, for the purpose of entering into a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination with one or more businesses.

In connection with the formation of the Sponsor, the Sponsor received 10,000,000 Class B ordinary shares for a per share purchase price of approximately $0.003. Prior to the IPO, our Sponsor transferred 50,000 of its founder shares to each of Colin Weil, Gary Cookhorn and Rebecca Macieira-Kaufmann, in each case, at their original per share purchase price. As of the date of this proxy statement, the initial shareholders continue to own an aggregate of 10,000,000 founder shares.

On November 15, 2021, BCSA consummated its IPO of 30,000,000 units (the “units”), each consisting of one Class A ordinary share (the “public shares”) and one-half of one redeemable warrant (the “public warrants”) including the issuance of 3,900,000 units as a result of the underwriters’ partial exercise of their over-allotment option, at $10.00 per unit, generating gross proceeds of $300,000,000.

Simultaneously with the closing of the IPO, BCSA consummated the sale of an aggregate of 1,322,000 private placement units, each consisting of one Class A ordinary share and one-half of one redeemable warrant (the “private placement warrants”), at a price of $10.00 per private placement unit in a private placement to our Sponsor, generating gross proceeds to BCSA of $13,220,000. As of the date of this proxy statement, the Sponsor owns an aggregate of 1,322,000 private placement units.

Following the closing of the IPO on November 15, 2021, an amount of $306.0 million ($10.20 per unit) out of the net proceeds of the sale of the units in the IPO and the sale of the private placement units was placed in the trust account, which was invested in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (“Investment Company Act”), with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations, until the earlier of: (a) the completion of our initial business combination, (b) the redemption of any public shares properly submitted in connection with a shareholder vote to approve certain amendments to our Governing Documents, including a vote to approve an extension to the Current Outside Date, and (c) the redemption of our public shares if we are unable to complete the initial business combination within the period provided in our Governing Documents. Like most blank check companies, our Governing Documents provide for the return of the IPO proceeds held in the trust account to the public shareholders if we do not consummate a qualifying business combination on or before a certain date. In our case, such date is November 15, 2023. If the Articles Amendment Proposals are approved, we may elect to liquidate the remaining investments held in the trust account and maintain those funds in cash in an interest-bearing demand deposit account at a bank.

On February 3, 2023, BCSA held an extraordinary general meeting (the “Extension Meeting”) at which BCSA’s shareholders approved a proposal to amend the Company’s Governing Documents to extend the date by which it has to consummate a business combination from May 15, 2023 to November 15, 2023 (the “Initial Extension Amendment Proposal”). In connection with the vote to approve the Initial Extension Amendment Proposal, holders of 26,406,729 Class A ordinary shares of BCSA exercised their right to redeem their shares for cash at a redemption price of approximately $10.38 per share, for an aggregate redemption amount of approximately $274.2 million. As a result, approximately $274.2 million was removed from the Trust Account to redeem such shares and 4,915,271 Class A ordinary shares remained outstanding after the redemption, including 1,322,000 shares underlying the Private Placement Units. As of the record date, BCSA had approximately $[ ] of cash in the trust account.

While we and the other parties to the Business Combination Agreement are working toward satisfaction of the conditions to completion of the Proposed Business Combination, our Board has determined that it is in the best interests of BCSA to amend the Governing Documents to further extend the date we have to consummate a business combination to May 15, 2024 in order to allow BCSA more time to complete the Proposed Business Combination, or any potential alternative initial business combination. Therefore, our Board is submitting the proposals described in this proxy statement for the shareholders to vote upon.

Does the Company need to hold an Annual General Meeting?

Nasdaq Listing Rule 5620(a) requires that we hold an annual meeting of shareholders within 12 months after our fiscal year ended December 31, 2022. We are holding this Extraordinary General Meeting in lieu of our 2023 annual general meeting. To comply with Nasdaq Listing Rule 5620(a), members of our management will be available at the Extraordinary General Meeting to discuss and answer questions regarding Company affairs generally, in addition to specific questions about the proposals described herein. In addition to sending our shareholders this Proxy Statement, we are also sending our Annual Report on Form 10-K for the year ended December 31, 2022.

What is being voted on?

You are being asked to vote on each of the Extension Amendment Proposal, Redemption Limitation Amendment Proposal, Founder Share Amendment Proposal and, if presented, the Adjournment Proposal. These proposals are briefly described below and in greater detail elsewhere in this proxy statement:

1. Extension Amendment Proposal: as a special resolution, to amend our Governing Documents to extend the date by which BCSA must consummate a business combination from November 15, 2023 to May 15, 2024 or such earlier date as may be determined by the Board in its sole discretion.

2. Redemption Limitation Amendment Proposal: as a special resolution, to amend the Governing Documents to eliminate the limitation that BCSA may not redeem public shares in an amount that would cause BCSA’s net tangible assets to be less than $5,000,001either immediately prior to or upon consummation of a business combination.

3. Founder Share Amendment Proposal: as a special resolution, to amend the Governing Documents to permit for the issuance of Class A ordinary shares to holders of Class B ordinary shares upon the exercise of the right of a holder of BCSA’s Class B ordinary shares to convert such holder’s Class B ordinary shares into Class A ordinary shares on a one-for-one basis at any time and from time to time prior to the closing of an initial business combination at the election of the holder.

4. Adjournment Proposal: as an ordinary resolution, to approve the adjournment of the Extraordinary General Meeting to a later date or dates, if necessary, either to permit further solicitation and vote of proxies in the event that there are insufficient votes to approve any of the Articles Amendment Proposals or if we determine that it is otherwise necessary or the Board determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.

The Adjournment Proposal will only be presented at the Extraordinary General Meeting if there are insufficient votes to approve one or more of the Articles Amendment Proposals at the Extraordinary General Meeting or the Board otherwise determines adjournment is necessary or determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.

What are the purposes of the Articles Amendment Proposals and the Adjournment Proposal?

On November 10, 2022, we entered into the Business Combination Agreement with Merger Sub and Qenta Inc. The sole purpose of the Extension Amendment Proposal is to provide us with sufficient time to complete our initial business combination. Our current Governing Documents provide that BCSA has until the Current Outside Date (November 15, 2023) to complete a business combination. While we and the other parties to the Business Combination Agreement are working toward satisfaction of the conditions to completion of the Proposed Business Combination, our Board believes that there may not be sufficient time to complete the SEC review process and hold an extraordinary general meeting to obtain shareholder approval of and consummate the Proposed Business Combination by the Current Outside Date. Accordingly, we have determined to seek shareholder approval to extend the Current Outside Date to the Extended Date.

Table of Contents

The purpose of the Founder Share Amendment Proposal is to provide the holders of Class B ordinary shares with the flexibility to assist the Company in meeting the listing requirements of its Class A ordinary shares if necessary or desirable in connection with the Articles Amendment Proposals and the consummation of an initial business combination. For example, if there are significant requests for redemption such that upon completing the redemptions the Company no longer satisfies the listing criteria set forth in Nasdaq Listing Rule 5450, the Founder Share Amendment Proposal will provide an avenue for regaining compliance. This flexibility may also assist the Company in retaining investors. Notwithstanding conversion of Class B ordinary shares into Class A ordinary shares, the holders of such converted shares have already waived and will not be entitled to receive any monies held in the trust account as a result of its ownership of any Class A ordinary shares.

The purpose of the Adjournment Proposal is to allow BCSA to adjourn the Extraordinary General Meeting to a later date or dates if we determine that additional time is necessary either to permit further solicitation and vote of proxies in the event that there are insufficient votes to approve one or more of the Articles Amendment Proposals at the Extraordinary General Meeting or if we determine that it is otherwise necessary or the Board determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals. The Board may exercise its discretion to adjourn the Extraordinary General Meeting indefinitely.

Approval of each of the Redemption Limitation Amendment Proposal and Founder Share Amendment Proposal is cross-conditioned on the approval of the Extension Amendment Proposal. If the Articles Amendment Proposals are approved, such approval will constitute consent for BCSA to remove the Withdrawal Amount from the trust account, deliver to the holders of redeemed public shares their portion of the Withdrawal Amount and retain the remainder of the funds in the trust account for BCSA’s use in connection with consummating a business combination on or before the Extended Date. The removal of the Withdrawal Amount from the trust account will reduce the amount held in the trust account following the Election.

Why should I vote for the Extension Amendment Proposal?

Our Board believes shareholders will benefit from BCSA consummating a business combination and is proposing the Extension Amendment Proposal to extend the date by which BCSA must complete a business combination until the Extended Date. The Extension would give BCSA the opportunity to complete the Proposed Business Combination, or any potential alternative initial business combination, which our Board believes in the best interests of the shareholders.

Table of Contents

Our Governing Documents provide that if our shareholders approve an amendment to our Governing Documents that would affect the substance or timing of our obligation to redeem 100% of BCSA’s public shares if BCSA does not complete a business combination by the Current Outside Date, we will provide our public shareholders with the opportunity to redeem all or a portion of their public shares in connection with such approval at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. This provision was included in the Governing Documents to protect our shareholders from having to sustain their investments for an unreasonably long period if we failed to find a suitable business combination in the timeframe contemplated by the Governing Documents. We also believe, however, that given our expenditure of time, effort and money on pursuing potential business combination opportunities, circumstances warrant providing our public shareholders an opportunity to consider the Proposed Business Combination, or any potential alternative initial business combination.

Our Board recommends that you vote in favor of the Extension Amendment Proposal, but expresses no opinion as to whether you should redeem your public shares.

Why should I vote for the Redemption Limitation Amendment Proposal?

The Board believes that the Redemption Limitation may prevent BCSA from completing an initial business combination and is not needed. The purpose of the Redemption Limitation was initially to ensure that the public shares not deemed to be a “penny stock” pursuant to Rule 3a51-1 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), in the event that such public shares failed to be listed on an approved national securities exchange. The Company now intends to rely on a different exclusion set forth in the Exchange Act as a result of its securities being listed on Nasdaq. Because the public shares would not be deemed to be a “penny stock” as such securities are listed on a national securities exchange, the Company is presenting the Redemption Limitation Amendment Proposal to facilitate the consummation of the Extension and a business combination. If the Redemption Limitation Amendment Proposal is not approved or not implemented and there are significant requests for redemption such that the Company’s net tangible assets would be less than $5,000,001 immediately prior to or upon the consummation of an initial business combination, the Governing Documents would prevent the Company from being able to consummate an initial business combination even if all other conditions to closing are met.

Our Board recommends that you vote in favor of the Redemption Limitation Amendment Proposal, but expresses no opinion as to whether you should redeem your public shares.

Why should I vote for the Founder Share Amendment Proposal?

The purpose of the Founder Share Amendment Proposal is to provide the holders of Class B ordinary shares with the flexibility to assist BCSA in meeting the listing requirements of its Class A ordinary shares if necessary or desirable in connection with the extension and the consummation of an initial business combination. For example, if there are significant requests for redemption such that upon completing the redemptions BCSA no longer satisfies the listing criteria set forth in Nasdaq Listing Rule 5450, the Founder Share Amendment Proposal will provide an avenue for regaining compliance. This flexibility may also assist BCSA in retaining investors. Notwithstanding conversion of Class B ordinary shares into Class A ordinary shares, the holders of such converted shares have already waived and will not be entitled to receive any monies held in the trust account as a result of its ownership of any Class A ordinary shares.

Our Board recommends that you vote in favor of the Founder Shares Amendment Proposal, but expresses no opinion as to whether you should redeem your public shares.

Why should I vote for the Adjournment Proposal?

If the Adjournment Proposal is presented and is not approved by our shareholders, we may not be able to adjourn the Extraordinary General Meeting to a later date in the event that there are insufficient votes for, or otherwise in connection with, the approval of one or more of the Articles Amendment Proposals or if BCSA determines that it is otherwise necessary or in the event that the Board determines it is no necessary or no longer desirable to proceed with the Articles Amendment Proposals.

Our Board recommends that you vote in favor of the Adjournment Proposal.

How do BCSA insiders intend to vote their shares?

The Sponsor, which is an affiliate of certain members of the Board and BCSA’s management team (the “initial shareholders”) are expected to vote any ordinary shares over which they have voting control in favor of each of the proposals. On the record date, the initial shareholders beneficially owned and were entitled to vote 10,000,000 founder shares and 1,322,000 private placement shares, which represent 76.0% of BCSA’s issued and outstanding ordinary shares.

The initial shareholders have agreed to waive their redemption rights with respect to their founder shares and public shares, as applicable, in connection with a shareholder vote to approve certain amendments to BCSA’s Governing Documents, including a vote to approve an extension to the Current Outside Date. In addition, they have agreed to waive their right to receive liquidating distributions from the trust account with respect to any founder shares they hold if we fail to consummate an initial business combination by the Current Outside Date.

Does the Board recommend voting for the approval of the Articles Amendment Proposals and, if presented, the Adjournment Proposal?

Yes. After careful consideration of the terms and conditions of the proposals, the Board has determined that the Articles Amendment Proposals and, if presented, the Adjournment Proposal are in the best interests of BCSA and its shareholders. The Board unanimously recommends that shareholders vote “FOR” each of the Extension Amendment Proposal, Redemption Limitation Amendment Proposal, Founder Share Amendment Proposal and, if presented, the Adjournment Proposal.

If the Adjournment Proposal is presented, what is the Resolution to be voted upon?

The full text of the resolution to be proposed is as follows:

“RESOLVED, as an ordinary resolution, that the general meeting be adjourned to a later date or dates to be determined by the chairman of the general meeting, either (x) to permit further solicitation and vote of proxies or if the Company determines that it is otherwise necessary or (y) because the board of directors has determined that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.”

What happens if I sell my public shares or units before the Extraordinary General Meeting?

The August 29, 2023 record date is earlier than the date of the Extraordinary General Meeting. If you transfer your public shares, including those shares held as a constituent part of our units, after the record date, but before the Extraordinary General Meeting, unless the transferee obtains from you a proxy to vote those shares, you will retain your right to vote at the Extraordinary General Meeting. If you transfer your public shares prior to the record date, you will have no right to vote those shares at the Extraordinary General Meeting. If you acquired your public shares after the record date, you will still have an opportunity to redeem them if you so decide.

What if I don’t want to vote for one or more of the Articles Amendment Proposals and/or the Adjournment Proposal?

If you do not want one or more of the Articles Amendment Proposals or, if presented, the Adjournment Proposal to be approved, you must vote “AGAINST” such proposal.

Will you seek any further extensions to liquidate the trust account?

Other than the extension until the Extended Date as described in this proxy statement, we do not currently anticipate seeking any further extension to consummate our initial business combination, although we may determine to do so in the future.

Table of Contents

What happens if the Extension Amendment Proposal is not approved?

If the Extension Amendment Proposal is not approved, BCSA may again seek to extend the Current Outside Date. If the Extension Amendment Proposal is not approved, the Current Outside Date is not otherwise extended and BCSA has not consummated an initial business combination by the Current Outside Date, BCSA will (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to us to pay our franchise and income taxes, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any, subject to applicable law); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our Board, liquidate and dissolve, subject in each case to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable laws. In addition, there will be no redemption rights or liquidating distributions with respect to our warrants, which will expire worthless in the event that BCSA winds up, liquidates and dissolves.

Our initial shareholders have agreed to waive their redemption rights with respect to their founder shares and public shares, as applicable, in connection with a shareholder vote to approve certain amendments to our Governing Documents, including a vote to approve an extension to the Current Outside Date. In addition, they have agreed to waive their right to receive liquidating distributions from the trust account with respect to any founder shares they hold if we fail to consummate an initial business combination by the Current Outside Date.

If the Extension Amendment Proposal is approved, what happens next?

If the Extension Amendment Proposal is approved, BCSA will file an amendment to its Governing Documents with the Registrar of Companies of the Cayman Islands in the form of Annex A hereto and will continue to attempt to consummate its initial business combination until the Extended Date. BCSA will remain a reporting company under the Exchange Act, and its units, public shares, and public warrants will remain publicly traded.

In addition, BCSA will redeem any public shares properly tendered for redemption in accordance with the procedures described herein and the removal of the Withdrawal Amount from the trust account in connection with the Election will reduce the amount held in the trust account following the Election.

BCSA cannot predict the amount that will remain in the trust account after such withdrawal if the Extension Amendment Proposal is approved and the amount remaining in the trust account may be only a fraction of the $[ ] million, plus accrued interest (less any funds used to pay taxes) that was in the trust account as of the record date. In such event, BCSA may still seek to obtain additional funds to complete its initial business combination and there can be no assurance that such funds will be available on terms acceptable to the parties or at all. The removal of the Withdrawal Amount from the trust account will further increase the percentage interest of BCSA ordinary shares held by our initial shareholders.

How are the funds in the trust account currently being held?

The funds in the trust account have, since our IPO, been held only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds investing solely in U.S. government treasury obligations and meeting certain conditions under Rule 2a-7 under the Investment Company Act. As of the record date, amounts held in the trust account included approximately $[ ] of accrued interest.

Please also read the section in our Annual Report on Form 10-K for the year ended December 31, 2022 entitled “Risk Factors — If we are deemed to be an investment company under the Investment Company Act, we may be required to institute burdensome compliance requirements and our activities may be restricted, which may make it difficult for us to complete our initial Business Combination.” To mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, we may, at any time, have to liquidate the securities held in the trust account and instead hold all funds in the trust account in cash until the earlier of the consummation of our initial business combination or our liquidation. Following any such liquidation, we will likely

Table of Contents

receive minimal interest, if any, on the funds held in the trust account, which would reduce the dollar amount that our public shareholders would receive upon any redemption or liquidation of BCSA. If the Articles Amendment Proposals are approved, we may elect to liquidate the remaining investments held in the trust account and maintain those funds in cash in an interest-bearing demand deposit account at a bank.

If I do not redeem my shares now, would I still be able to vote on an initial business combination and exercise my redemption rights with respect to an initial business combination?

Yes. If you do not redeem your shares in connection with the Articles Amendment Proposals, then, assuming you are a shareholder as of the record date for voting on the Proposed Business Combination, or any potential alternative initial business combination, you will be able to vote on such business combination when it is submitted to shareholders. You will also retain your right to redeem your public shares upon consummation of such business combination, subject to any limitations set forth in the Governing Documents.

How do I vote?

If you are a holder of record of BCSA’s ordinary shares, including those shares held as a constituent part of our units, you may vote at the Extraordinary General Meeting or by submitting a proxy for the Extraordinary General Meeting. Whether or not you plan to attend the Extraordinary General Meeting virtually or in person, we urge you to vote by proxy to ensure your vote is counted. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope. You may still attend the Extraordinary General Meeting and vote in person physically or virtually if you have already voted by proxy.

If your ordinary shares of BCSA, including those shares held as a constituent part of our units, are held in “street name” by a broker or other agent, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Extraordinary General Meeting, whether in person physically or via live webcast. However, since you are not the shareholder of record, you may not vote your shares virtually at the Extraordinary General Meeting unless you request and obtain a valid proxy from your broker or other agent.

How do I change my vote?

If you have submitted a proxy to vote your shares and wish to change your vote, you may do so by delivering a later-dated, signed proxy card prior to the date of the Extraordinary General Meeting or by voting at the Extraordinary General Meeting in person physically or virtually. Attendance at the Extraordinary General Meeting alone will not change your vote. You also may revoke your proxy by sending a notice of revocation to BCSA at:

PO Box 1093, Boundary Hall

Attn: Corporate Secretary

How are votes counted?

Votes will be counted by the inspector of election appointed for the Extraordinary General Meeting, who will separately count “FOR” and “AGAINST” votes, abstentions and broker non-votes for each of the proposals.

Abstentions will be counted for the purpose of establishing a quorum, but broker non-votes will not. Abstentions and broker non-votes will not count as votes cast and will have no effect on the outcomes of the votes on the Articles Amendment Proposals or the Adjournment Proposal.

For more information regarding broker non-votes, please read the question “If my shares are held in “street name,” will my broker automatically vote them for me?” below.

If my shares are held in “street name,” will my broker automatically vote them for me?

No. Holders of ordinary shares that are held in street name must instruct their bank or brokerage firm that holds their shares how to vote their shares. If you do not give instructions to your bank or brokerage firm, the bank or brokerage firm will nevertheless be entitled to vote your shares with respect to “routine” items, but it will not be permitted to vote your shares with respect to “non-routine” items.

We believe all of the proposals will be considered “non-routine”, meaning that your broker can only vote your shares with respect to such proposals if you provide instructions on how to vote. You should instruct your broker or brokerage firm to vote your shares. Your broker can tell you how to provide these instructions. If you do not give your broker or brokerage firm instructions, your shares may be treated as broker non-votes with respect to such proposals. Please read the question “How are votes counted?” above for more information regarding the effect of broker non-votes.

What is a quorum requirement?

A quorum of shareholders is necessary to hold a valid meeting. A quorum will be present if the holders of a majority of our ordinary shares, including those shares held as a constituent part of our units, are present in person (including via live webcast) or by proxy at the Extraordinary General Meeting. If there is no quorum, the chairperson of the Extraordinary General Meeting may adjourn the Extraordinary General Meeting to another date. Abstentions will be counted towards the quorum requirement, but broker non-votes will not.

Who can vote at the Extraordinary General Meeting?

Only holders of record of BCSA’s ordinary shares, including those shares held as a constituent part of our units, at the close of business on August 29, 2023, are entitled to have their vote counted at the Extraordinary General Meeting and any adjournments or postponements thereof. On the record date, 4,915,271 Class A ordinary shares and 10,000,000 Class B ordinary shares were outstanding and entitled to vote.

Shareholder of Record: Shares Registered in Your Name. If on the record date your shares or units were registered directly in your name with BCSA’s transfer agent, Continental Stock Transfer & Trust Company, then you are a shareholder of record. As a shareholder of record, you may vote in person physically or virtually at the Extraordinary General Meeting or vote by proxy. Whether or not you plan to attend the Extraordinary General Meeting, we urge you to fill out and return the enclosed proxy card to ensure your vote is counted.

Beneficial Owner: Shares Registered in the Name of a Broker or Bank. If on the record date your shares or units were held, not in your name, but rather in an account at a brokerage firm, bank, dealer, or other similar organization, then you are the beneficial owner of shares held in “street name” and these proxy materials are being forwarded to you by that organization. As a beneficial owner, you have the right to direct your broker or other agent on how to vote the shares in your account. You are also invited to attend the Extraordinary General Meeting in person physically or virtually. However, since you are not the shareholder of record, you may not vote your shares in person physically or virtually at the Extraordinary General Meeting unless you request and obtain a valid proxy from your broker or other agent.

What interests do BCSA’s directors and executive officers have in the approval of the Articles Amendment Proposals?

BCSA’s directors and executive officers have interests in the Articles Amendment Proposals that may be different from, or in addition to, your interests as a shareholder. These interests include ownership by them of founder shares, and warrants that may become exercisable in the future, and the possibility of future compensatory arrangements. See the section entitled “Interests of BCSA’s Directors and Officers”.

What if I object to the Articles Amendment Proposals? Do I have dissenters’ rights?

Neither Cayman Islands nor BCSA’s Governing Documents provide shareholders with dissenters’ rights in connection with the Articles Amendment Proposals or, if presented, the Adjournment Proposal.

What happens to BCSA’s warrants if the Articles Amendment Proposals are not approved?

If the Articles Amendment Proposals are not approved, we may again seek to extend the Current Outside Date. If the Articles Amendment Proposals are not approved, the Current Outside Date is not otherwise extended and we have not consummated an initial business combination by the Current Outside Date, our Governing Documents require that BCSA liquidate and dissolve, subject to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable laws. There will be no distribution from the trust account with respect to our warrants, which will expire worthless in the event BCSA winds up, liquidates and dissolves. Our initial shareholders have agreed to waive their redemption rights with respect to their founder shares and public shares, as applicable, in connection with a shareholder vote to approve certain amendments to our Governing Documents, including a vote to approve an extension to the Current Outside Date. In addition, they have agreed to waive their right to receive liquidating distributions from the trust account with respect to any founder shares they hold if we fail to consummate an initial business combination within the time period prescribed by our Governing Documents.

What happens to BCSA’s warrants if the Articles Amendment Proposals are approved?

If the Articles Amendment Proposals are approved, we will continue our efforts to consummate the Proposed Business Combination, or a potential alternative initial business combination, until the Extended Date and will retain the blank check company restrictions previously applicable to us. Our warrants will remain outstanding in accordance with their terms.

How do I redeem my public shares?

In connection with approval of the Articles Amendment Proposals at the Extraordinary General Meeting, each public shareholder may seek to redeem all or a portion of his or her public shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account as of two business days prior to such approval, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the total number of then outstanding public shares. Public shareholders are entitled to seek redemption whether they vote “AGAINST”, abstain or do not vote on any of the proposals. However, public shareholders will only be entitled to receive cash for any public shares to be redeemed only if they:

(i) (a) hold public shares or (b) hold public shares through units and elect to separate their units into the underlying public shares and public warrants prior to exercising their redemption rights with respect to the public shares; and

(ii) prior to 5:00 p.m. Eastern Time, on September [ ], 2023 (two business days prior to the scheduled vote at the Extraordinary General Meeting), (a) submit a written request, including the name, phone number, and address of the beneficial owner of the shares for which redemption is requested, to Continental Stock Transfer & Trust Company, BCSA’s transfer agent, at Continental Stock Transfer & Trust Company, 1 State Street, 30th Floor, New York, New York 10004, Attn: Mark Zimkind (e-mail: mzimkind@continentalstock.com), that BCSA redeem their public shares for cash and (b) tender or deliver their shares to the transfer agent (and share certificates (if any) and other redemption forms), physically or electronically through The Depository Trust Company (“DTC”).

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so. Public shareholders may elect to redeem all or a portion of their public shares regardless of whether they vote for or against any of the Articles Amendment Proposals and regardless of whether they hold public shares on the record date.

If you hold your shares through a bank or broker, you must ensure your bank or broker complies with the requirements identified herein, including submitting a written request that your shares be redeemed for cash to the transfer agent and delivering your shares to the transfer agent prior to 5:00 p.m. Eastern Time on September [ ], 2023 (two business days before the scheduled vote at the Extraordinary General Meeting). You will only be entitled to receive cash in connection with a redemption of these shares if you continue to hold them through the time the Articles Amendment Proposals are approved and the redemptions are completed.

Through DTC’s DWAC (Deposit/Withdrawal at Custodian) System, this electronic delivery process can be accomplished by the shareholder, whether it is a record holder or its shares are held in “street name,” by contacting the transfer agent or its broker and requesting delivery of its shares through the DWAC system. Delivering shares physically may take significantly longer. In order to obtain a physical share certificate, a shareholder’s broker and/or clearing broker, DTC, and BCSA’s transfer agent will need to act together to facilitate this request. There is a nominal cost associated with the above-referenced tendering process and the act of certificating the shares or delivering them through the DWAC system. The transfer agent will typically charge the tendering broker $100 and the broker would determine whether or not to pass this cost on to the redeeming holder. It is our understanding that shareholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. BCSA does not have any control over this process or over the brokers or DTC, and it may take longer than two weeks to obtain a physical share certificate. Such shareholders will have less time to make their investment decision than those shareholders that deliver their shares through the DWAC system. Shareholders who request physical share certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares.

Table of Contents

In the event that a public shareholder tenders shares and the Articles Amendment Proposals are not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the shareholder promptly following the determination that the Extension Amendment Proposal will not be approved or that the Extension will not be implemented. BCSA anticipates that a public shareholder who tenders shares for redemption in connection with the vote to approve the Articles Amendment Proposals would receive payment of the redemption price for such shares soon after such approval. The transfer agent will hold the certificates of public shareholders that make the election until such shares are redeemed for cash or returned to such shareholders.

Public shareholders will also be able to redeem their public shares in connection with any shareholder vote to approve a business combination, or if BCSA has not consummated a business combination by the Extended Date.

If I am a unit holder, can I exercise redemption rights with respect to my units?

No. Holders of outstanding units must separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares.

If you hold units registered in your own name, you must deliver the certificate for such units to Continental Stock Transfer & Trust Company, our transfer agent, with written instructions to separate such units into public shares, and public warrants. This must be completed far enough in advance to permit the mailing of the public share certificates back to you so that you may then exercise your redemption rights upon the separation of the public shares from the units. See “How do I redeem my public shares?” above.

Who is paying for this proxy solicitation?

BCSA will pay for the entire cost of soliciting proxies. In addition, our directors and executive officers may also solicit proxies in person, by telephone or by other means of communication, but will not be paid any additional compensation for soliciting proxies. BCSA may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

Where do I find the voting results of the Extraordinary General Meeting?

We will announce preliminary voting results at the Extraordinary General Meeting. The final voting results will be tallied by the inspector of election and published in BCSA’s Current Report on Form 8-K, which BCSA will file with the SEC within four business days following the Extraordinary General Meeting.

RISK FACTORS

You should consider carefully all of the risks described in our Annual Report on Form 10-K filed with the SEC on April 17, 2023, any subsequent Quarterly Report on Form 10-Q filed with the SEC and in the other reports we file with the SEC before making a decision to invest in our securities. Furthermore, if any of the following events occur, our business, financial condition and operating results may be materially adversely affected or we could face liquidation. In that event, the trading price of our securities could decline, and you could lose all or part of your investment. The risks and uncertainties described in the aforementioned filings and below are not the only ones we face. Additional risks and uncertainties that we are unaware of, or that we currently believe are not material, may also become important factors that adversely affect our business, financial condition and operating results or result in our liquidation.

We may not be able to complete the Proposed Business Combination or any potential alternative initial business combination by the expiration of the Extended Date, even if the Articles Amendment Proposals are approved by our shareholders, in which case, to the extent we do not obtain any further extension, we would cease all operations except for the purpose of winding up and we would redeem our public shares and liquidate and dissolve.

We may not be able to complete the Proposed Business Combination or an alternative business combination by the expiration of the Extended Date, even if the Articles Amendment Proposals are approved by our shareholders. Our ability to complete the Proposed Business Combination or an alternative business combination may be negatively impacted by general market conditions, volatility in the capital and debt markets and the other risks described herein, in our 2022 Annual Report, and in other reports that we file with the SEC.

If we have not completed our initial business combination prior to the Extended Date (assuming that the Articles Amendment Proposals are approved), and we do not seek any further extension, we will be required to (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including interest earned on the funds held in the trust account and not previously released to BCSA to pay its franchise and income taxes, if any (less up to $100,000 of interest to pay dissolution expenses) divided by the number of the then-outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any, subject to applicable law); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of BCSA’s remaining shareholders and its board of directors, liquidate and dissolve, subject in each case to BCSA’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable laws. In addition, there will be no redemption rights or liquidating distributions with respect to BCSA’s warrants, including the public warrants, which will expire worthless in the event BCSA winds up, liquidates and dissolves.

In addition, we are required to offer our public shareholders the opportunity to redeem Class A ordinary shares in connection with the Articles Amendment Proposals and will be required to offer our public shareholders redemption rights again in connection with any shareholder vote to approve our initial business combination. Even if the Articles Amendment Proposals or initial business combination are approved by our shareholders, it is possible that redemptions will leave us with insufficient cash to consummate an initial business combination on commercially acceptable terms, or at all. The fact that we will have separate redemption periods in connection with the Articles Amendment Proposals and our initial business combination vote could exacerbate these risks, The ability of our public shareholders to exercise such redemption rights with respect to a large number of our public shares may also adversely affect the liquidity of our Class A ordinary shares. As a result, you may be unable to sell your Class A ordinary shares even if the per-share market price is higher than the per-share redemption price paid to public shareholders that elect to redeem their public shares if the Extension Amendment Proposal is approved.

Table of Contents

If following the approval of the Articles Amendment Proposals we are no longer in compliance with Nasdaq’s continued listing requirements, Nasdaq may delist our securities from trading on its exchange, which could limit investors’ ability to make transactions in our securities and subject us to additional trading restrictions.

Our units, Class A ordinary shares and public warrants are currently listed on the Nasdaq Global Market (“Nasdaq”), a national securities exchange. We cannot assure you that our securities will continue to be listed on Nasdaq in the future prior to an initial business combination, including following any shareholder redemptions in connection with certain amendments to the Governing Documents, such as the Articles Amendment Proposals. If the public shareholders exercise redemption rights with respect to a large number of our Class A ordinary shares in connection with the approval of the Articles Amendment Proposals, our securities may no longer meet Nasdaq’s continued listing requirements and Nasdaq may delist our securities from trading on its exchange.

We expect that if our Class A ordinary shares fail to meet Nasdaq’s continued listing requirements, our units and warrants will also fail to meet Nasdaq’s continued listing requirements for those securities. We cannot assure you that any of our Class A ordinary shares, units or warrants will be able to meet any of Nasdaq’s continued listing requirements following the Extraordinary General Meeting and any shareholder redemptions of our Class A ordinary shares in connection with the approval of the Articles Amendment Proposals. If Nasdaq delists any of our securities from trading on its exchange and we are not able to list such securities on another national securities exchange, we expect such securities could be quoted on an over-the-counter market. However, if this were to occur, we could face significant material adverse consequences, including:

• a limited availability of market quotations for our securities;

• reduced liquidity for our securities;

• a determination that our Class A ordinary shares are a “penny stock” which will require brokers trading in our Class A ordinary shares to adhere to more stringent rules, possibly resulting in a reduced level of trading activity in the secondary trading market for our securities;

• a limited amount of news and analyst coverage; and

• a decreased ability to issue additional securities or obtain additional financing in the future.

The National Securities Markets Improvement Act of 1996, which is a federal statute, prevents or preempts the states from regulating the sale of certain securities, which are referred to as “covered securities.” Because our units, Class A ordinary shares and public warrants are currently listed on Nasdaq, our units, Class A ordinary shares and public warrants qualify as covered securities under such statute. Although the states are preempted from regulating the sale of our securities, the federal statute does allow the states to investigate companies if there is a suspicion of fraud, and, if there is a finding of fraudulent activity, then the states can regulate or bar the sale of covered securities in a particular case. Certain state securities regulators might view blank check companies unfavorably and use any powers they may have to prohibit or restrict the sale of securities issued by blank check companies, or threaten to use these powers, to hinder the sale of securities of blank check companies in their states. Further, if we were no longer listed on Nasdaq, our securities would not qualify as covered securities under such statute and we would be subject to regulation in each state in which we offer our securities.

Our Sponsor, certain members of our Board and our officers have interests in the proposals that may conflict with those of other shareholders in recommending that shareholders vote in favor of approval of the proposals. For example, Our initial shareholders have agreed to waive their redemption rights with respect to their founder shares and public shares, as applicable, in connection with a shareholder vote to approve certain amendments to BCSA’s Governing Documents, including a vote to approve an extension to the Current Outside Date. In addition, they have agreed to waive their right to receive liquidating distributions from the trust account with respect to any founder shares they hold if BCSA fails to consummate an initial business combination within the time period prescribed by the Governing Documents. As a result, founder shares held by the Sponsor and BCSA’s independent directors will be worthless, as will the warrants underlying the Sponsor’s private placement units, if the Articles Amendment Proposals are not approved and we do not consummate an initial business combination by November 15, 2023.

Table of Contents

These interests may influence our directors in making their recommendation that you vote in favor of the approval of the proposals described in this proxy statement. You should take these interests into account in deciding whether to vote in favor of such proposals. You should also read the section entitled “Interests of BCSA’s Directors and Officers.”

If we instruct the trustee to liquidate the securities held in the trust account and instead to hold the funds in the trust account in cash until the earlier of the consummation of an initial business combination or our liquidation, we may be able to mitigate the risk that we could be deemed to be an investment company for purposes of the Investment Company Act. Following the liquidation of securities in the trust account, we may receive minimal interest, if any, on the funds held in the trust account, which may reduce the dollar amount the public shareholders would receive upon any redemption or liquidation of our company.

The funds in the trust account are held in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds investing solely in U.S. government treasury obligations and meeting certain conditions under Rule 2a-7 under the Investment Company Act. However, to mitigate the risk of us being deemed to be an unregistered investment company (including under the subjective test of Section 3(a)(1)(A) of the Investment Company Act) and thus subject to regulation under the Investment Company Act, we may, at any time, instruct the trustee with respect to the trust account to liquidate the U.S. government treasury obligations or money market funds held in the trust account and thereafter to hold all funds in the trust account in cash in an interest-bearing demand deposit account at a national bank until the earlier of consummation of an initial business combination or liquidation of our company. Following such liquidation of the securities held in the trust account, we may receive minimal interest, if any, on the funds held in the trust account. However, interest previously earned on the funds held in the trust account still may be released to us to pay our taxes, if any, and certain other expenses as permitted. As a result, any decision to liquidate the securities held in the trust account and thereafter to hold all funds in the trust account in cash may reduce the dollar amount the public shareholders would receive upon any future redemption or liquidation of BCSA.

THE EXTRAORDINARY GENERAL MEETING

Date, Time, Place and Purpose of the Extraordinary General Meeting

The Extraordinary General Meeting will be held at [ ] [a.m./p.m.] Eastern Time, on September [ ], 2023. You will be able to attend the Extraordinary General Meeting online, vote, and submit your questions during the Extraordinary General Meeting by visiting https://www.cstproxy.com/blockchaincac1/sm2023. While shareholders are encouraged to attend the meeting virtually, you will be permitted to attend the Extraordinary General Meeting in person at the physical location of the Extraordinary General Meeting at the offices of Perkins Coie LLP located at 1120 NW Couch Street, 10th Floor, Portland, OR 97209, United States of America.

The Extraordinary General Meeting is being held to consider and vote upon the following proposals:

Voting Power; Record Date

You will be entitled to vote or direct votes to be cast at the Extraordinary General Meeting if you owned our ordinary shares, including as a constituent part of a unit, at the close of business on August 29, 2023, the record date for the Extraordinary General Meeting. You will have one vote for each ordinary share you owned at that time. Our warrants do not carry voting rights.

If your shares are held in “street name” or are in a margin or similar account, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted.

At the close of business on the record date, there were 4,915,271 Class A ordinary shares issued and outstanding, which includes an aggregate of 1,322,000 private placement shares, and 10,000,000 Class B ordinary shares issued and outstanding, which vote together as a single class with respect to each of the Articles Amendment Proposals and, if presented, the Adjournment Proposal. BCSA’s warrants do not have voting rights in connection with any of the Articles Amendment Proposals or the Adjournment Proposal.

Votes Required

Approval of each of the Articles Amendment Proposals will require a special resolution under Cayman Islands law, being the affirmative vote of at least a two-thirds (2/3) majority of the votes cast by the holders of the issued ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter, including those shares held as a constituent part of our units, on the

record date. As of the date of this proxy statement, the initial shareholders hold approximately 76.0% of BCSA’s outstanding ordinary shares. Approval of each of the Redemption Limitation Amendment Proposal and Founder Share Amendment Proposal is cross-conditioned on the approval of the Extension Amendment Proposal.

If presented, the Adjournment Proposal requires an ordinary resolution under Cayman Islands law, being the affirmative vote of a simple majority of the votes cast by the holders of the issued ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter.

If you do not want the Articles Amendment Proposals or, if presented, the Adjournment Proposal to be approved, you must vote “AGAINST” such proposals. We anticipate that a public shareholder who tenders shares for redemption in connection with the vote to approve the Articles Amendment Proposals would receive payment of the redemption price for such shares soon after such approval.

Abstentions will be counted to determine whether a valid quorum is established, but broker non-votes will not. Abstentions and broker non-votes will have no effect on the outcomes of any of the proposals.

Voting

You can vote your shares at the Extraordinary General Meeting by proxy or in person, either physically or virtually.

You can vote by proxy by having one or more individuals who will attend the Extraordinary General Meeting vote your shares for you. These individuals are called “proxies” and using them to cast your vote at the Extraordinary General Meeting is called voting “by proxy.”

If you wish to vote by proxy, you must (i) complete the enclosed form, called a “proxy card,” and mail it in the envelope provided or (ii) submit your proxy by telephone or over the internet (if those options are available to you) in accordance with the instructions on the enclosed proxy card or voting instruction card.

If you complete the proxy card and mail it in the envelope provided or submit your proxy by telephone or over the internet as described above, you will designate Mitchell Mechigian or, failing him, Lou Kerner or, failing him, the duly appointed chairman to act as your proxy at the Extraordinary General Meeting. One of them will then vote your shares at the Extraordinary General Meeting in accordance with the instructions you have given them in the proxy card or voting instructions, as applicable, with respect to the proposals presented in this proxy statement. Proxies will extend to, and be voted at, any adjournments or postponements of the Extraordinary General Meeting.

Alternatively, you can vote your shares in person by attending the Extraordinary General Meeting virtually or at the offices of Perkins Coie LLP.

A special note for those who plan to attend the Extraordinary General Meeting and vote: if your shares or units are held in the name of a broker, bank or other nominee, please follow the instructions you receive from your broker, bank or other nominee holding your shares. You will not be able to vote at the Extraordinary General Meeting unless you obtain a legal proxy from the record holder of your shares.

Our Board is asking for your proxy. Giving our Board your proxy means you authorize it to vote your shares at the Extraordinary General Meeting in the manner you direct. You may vote for or against any proposal or you may abstain from voting. All valid proxies received prior to the Extraordinary General Meeting will be voted. All shares represented by a proxy will be voted, and where a shareholder specifies by means of the proxy a choice with respect to any matter to be acted upon, the shares will be voted in accordance with the specification so made. If no choice is indicated on the proxy, the shares will be voted “FOR” each of the Articles Amendment Proposals and, if presented, the Adjournment Proposal, and as the proxy holders may determine in their discretion with respect to any other matters that may properly come before the Extraordinary General Meeting.

Table of Contents

Shareholders who hold their shares in “street name,” meaning the name of a broker or other nominee who is the record holder, must either direct the record holder of their shares to vote their shares or obtain a legal proxy from the record holder to vote their shares at the Extraordinary General Meeting.

Revocability of Proxies

Any proxy may be revoked by the person giving it at any time before the polls close at the Extraordinary General Meeting. A proxy may be revoked by delivering to our Corporate Secretary, at Blockchain Coinvestors Acquisition Corp. I, PO Box 1093, Boundary Hall, Cricket Square, Grand Cayman, KY1-1102, Cayman Islands, either a written notice of revocation bearing a date later than the date of such proxy or a subsequent proxy relating to the same shares or by attending the Extraordinary General Meeting and voting in person physically or virtually.

Simply attending the Extraordinary General Meeting will not constitute a revocation of your proxy. If your shares are held in the name of a broker or other nominee who is the record holder, you must follow the instructions of your broker or other nominee to revoke a previously given proxy.

Redemption Rights

Each public shareholder may seek to redeem all or a portion of such public shareholder’s public shares even if they vote “AGAINST”, abstain from voting on or do not vote on the Articles Amendment Proposals. For more information regarding redemption rights and how to exercise them, please read the section titled “Redemption Rights” below.

Attendance at the Extraordinary General Meeting

Only holders of ordinary shares, their proxy holders and guests BCSA may invite may attend the Extraordinary General Meeting. If you wish to attend the Extraordinary General Meeting in person physically or virtually but you hold your shares or units through someone else, such as a broker, please follow the instructions you receive from your broker, bank or other nominee holding your shares. You must bring a legal proxy from the broker, bank or other nominee holding your shares, confirming your beneficial ownership of the shares and giving you the right to vote your shares.

Solicitation of Proxies

Your proxy is being solicited by our Board on the proposals being presented to the shareholders at the Extraordinary General Meeting. Our directors and executive officers may also solicit proxies in person, by telephone or by other means of communication, but will not be paid any additional compensation for soliciting proxies. BCSA may also reimburse brokerage firms, banks and other agents for the cost of forwarding proxy materials to beneficial owners.

The cost of preparing, assembling, printing and mailing this proxy statement and the accompanying form of proxy, and the cost of soliciting proxies relating to the Extraordinary General Meeting, will be borne by BCSA.

Some banks and brokers have customers who beneficially own ordinary shares listed of record in the names of nominees. BCSA intends to request banks and brokers to solicit such customers and will reimburse them for their reasonable out-of-pocket expenses for such solicitations. If any additional solicitation of the holders of our outstanding ordinary shares is deemed necessary, BCSA (through our directors and executive officers) anticipates making such solicitation directly.

No Right of Appraisal

BCSA’s shareholders do not have dissenters’ rights under Cayman Islands law nor BCSA’s Governing Documents in connection with the proposals to be voted on at the Extraordinary General Meeting.

Other Business

BCSA is not currently aware of any business to be acted upon at the Extraordinary General Meeting other than the matters discussed in this proxy statement. The form of proxy accompanying this proxy statement confers discretionary authority upon the named proxy holders with respect to amendments or variations to the matters identified in the accompanying Notice of Extraordinary General Meeting and with respect to any other matters which may properly come before the Extraordinary General Meeting.

PROPOSAL NO. 1 — THE EXTENSION AMENDMENT PROPOSAL

Overview

BCSA is proposing to amend its Governing Documents to further extend the date by which BCSA must consummate a business combination to May 15, 2024. Our Governing Documents currently provide that we have until November 15, 2023 to complete a business combination. A copy of the proposed amendment to our Governing Documents is attached to this proxy statement as Annex A.

BCSA is blank check company incorporated on June 11, 2021, as a Cayman Islands exempted company, for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses. On November 15, 2021, BCSA consummated its IPO of 30,000,000 units, including the issuance of 3,900,000 units as a result of the underwriters’ partial exercise of their over-allotment option. Each unit consists of one share of Class A ordinary share and one-half of one redeemable public warrant, with each whole warrant entitling the holder thereof to purchase one Class A ordinary share for $11.50 per share. The units were sold at a price of $10.00 per unit, generating total gross proceeds of $300,000,000.

Simultaneously with the closing of the IPO, BCSA consummated the sale of an aggregate of 1,322,000 private placement units at a price of $10.00 per private placement unit in a private placement to its Sponsor, generating gross proceeds to BCSA of $13,220,000. As of the date of this proxy statement, the Sponsor owns an aggregate of 1,322,000 private placement units. Each private placement unit consists of one Class A ordinary share and one-half of one private placement warrant. Each whole private placement warrant is exercisable to purchase one whole Class A ordinary share at $11.50 per share.

On November 10, 2022, we entered into the Business Combination Agreement, which provides for, among other things, the following transactions: (i) the Domestication and, in connection with the Domestication, (A) BCSA’s name will be changed to “Qenta Inc.” and (B) each of BCSA’s outstanding Class A ordinary shares and outstanding Class B ordinary shares will become one share of New Qenta Common Stock; and (ii) following the Domestication, the Merger.

Reasons for the Proposal

The sole purpose of the Extension Amendment Proposal is to provide BCSA with sufficient time to complete an initial business combination, which our Board believes is in the best interest of our shareholders.

On February 3, 2023, our shareholders approved the Initial Extension Amendment Proposal to extend the date by which we must consummate a business combination to November 15, 2023. Accordingly, the Governing Documents currently provide that we have until November 15, 2023 to complete an initial business combination. While we and the other parties to the Business Combination Agreement continue to work toward satisfaction of the conditions to completion of the Proposed Business Combination, our Board believes that there may not be sufficient time to complete the SEC review process and hold an extraordinary general meeting to obtain shareholder approval of and consummate the Proposed Business Combination, or any potential alternative initial business combination, by the Current Outside Date.

If we were precluded from completing our initial business combination by the Current Outside Date, we would be forced to liquidate even if our shareholders are otherwise in favor of consummating such business combination, we would be forced to (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, and subject to having lawfully available funds therefor, redeem 100% of the outstanding public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the trust account deposits (which interest shall

Table of Contents

be net of taxes payable and after setting aside up to $100,000 to pay dissolution expenses), divided by the total number of then outstanding public shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our Board, in accordance with applicable law, dissolve and liquidate, subject in each case to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. In addition, there will be no redemption rights or liquidating distributions with respect to BCSA’s warrants, which will expire worthless in the event BCSA winds up, liquidates and dissolves.

The Board believes that the initial business combination opportunity with Qenta is compelling and has determined that it is in the best interests of BCSA and its shareholders to extend the Current Outside Date to the Extended Date and have BCSA’s shareholders approve the Extension Amendment Proposal. We believe that given BCSA’s expenditure of time, effort and money on searching for potential business combination opportunities, its review of Qenta’s business and negotiations in connection with the Business Combination Agreement, circumstances warrant providing BCSA’s public shareholders an opportunity to consider the Proposed Business Combination, or a potential alternative initial business combination. Accordingly, since we may not be able to complete an initial business combination by the Current Outside Date, we have determined to seek shareholder approval to extend the time for closing a business combination beyond the Current Outside Date to the Extended Date.

If the Extension Amendment Proposal is Approved

If the Extension Amendment Proposal is approved, the Extension Amendment will be effective immediately upon such approval (provided that the Redemption Limitation Amendment Proposal and Founder Share Amendment Proposal are also approved) and we will file the amendment to BCSA’s Governing Documents with the Registrar of Companies of the Cayman Islands in the form of Annex A hereto. We will remain a reporting company under the Exchange Act, and our units, public shares, and public warrants will remain publicly traded. BCSA will then continue to work to consummate the Proposed Business Combination, or a potential alternative initial business combination, by the Extended Date.

If the Extension Amendment Proposal is approved, we plan to hold another general meeting prior to the Extended Date in order to seek shareholder approval of the Proposed Business Combination, or a potential alternative initial business combination, and related proposals. For more information regarding the Proposed Business Combination and the Business Combination Agreement, please read BCSA’s Current Report on Form 8-K relating to the Proposed Business Combination that was filed with the SEC on November 10, 2022, including the complete text of the Business Combination Agreement filed as an exhibit thereto.

You are not being asked to vote on any proposed business combination at this time. If the Extension Amendment Proposal is approved and you do not elect to redeem your public shares in accordance with the procedures described herein, you will retain the right to vote on the Proposed Business Combination, or any potential alternative initial business combination, when and if such business combination is submitted to the public shareholders (provided that you are a shareholder on the record date for a meeting to consider such business combination) and the right to redeem your public shares for a pro rata portion of the trust account in the event any proposed business combination is approved and completed or BCSA has not consummated a business combination by the Extended Date.

If the Extension Amendment Proposal is approved, the removal of the Withdrawal Amount from the trust account in connection with the Election will reduce the amount held in the trust account following the Election. BCSA cannot predict the amount that will remain in the trust account after such withdrawal if the Extension Amendment Proposal is approved and the amount remaining in the trust account may be only a fraction of the $[ ] million, plus accrued interest (less any funds used to pay taxes) that was in the trust account as of the record date. In such event, we may still seek to obtain additional funds to complete a business combination, and there can be no assurance that such funds will be available on terms acceptable to the parties or at all.

If the Extension Amendment Proposal is Not Approved

Because our initial shareholders are expected to vote their ordinary shares “FOR” approval of the Extension Amendment Proposal, as described below, we do not expect the Extension Amendment Proposal to fail.

If the Extension Amendment Proposal is not approved, BCSA may again seek to extend the Current Outside Date. In addition, because approval of each of the Redemption Limitation Amendment Proposal and Founder Share Amendment Proposal is cross-conditioned on the approval of the Extension Amendment Proposal, none of the Articles Amendment Proposals will be approved if the Extension Amendment Proposal is not approved. If the Extension Amendment Proposal is not approved, the Current Outside Date is not otherwise extended and we do not consummate an initial business combination by the Current Outside Date, in accordance with the Governing Documents, we will be required to liquidate as described above.

Required Vote

Approval of the Extension Amendment Proposal will require a special resolution under Cayman Islands law, being the affirmative vote of at least a two-thirds (2/3) majority of the votes cast by the holders of the issued ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter, including those shares held as a constituent part of our units, on the record date.

In addition, approval of each of the Redemption Limitation Amendment Proposal and Founder Share Amendment Proposal is cross-conditioned on the approval of the Extension Amendment Proposal.

The initial shareholders are expected to vote any ordinary shares over which they have voting control in favor of all of the proposals described in this proxy statement. On the record date, the initial shareholders beneficially owned and were entitled to vote an aggregate of 10,000,000 founder shares and the Sponsor beneficially owned and was entitled to vote 1,322,000 private placement shares, which shares represent, in aggregate, approximately 76.0% of BCSA’s issued and outstanding ordinary shares.

Recommendation

As discussed above, after careful consideration of all relevant factors, our Board has determined that the Extension Amendment Proposal is in the best interests of BCSA and its shareholders. Our Board has approved and recommends adoption of the Extension Amendment.

OUR BOARD RECOMMENDS THAT YOU VOTE “FOR” THE EXTENSION AMENDMENT PROPOSAL. OUR BOARD EXPRESSES NO OPINION AS TO WHETHER YOU SHOULD REDEEM YOUR PUBLIC SHARES.

The existence of financial and personal interests of our directors and officers may result in a conflict of interest on the part of one or more of the directors or officers between what such directors or officers may believe is in the best interests of BCSA and its shareholders and what such directors or officers may believe is best for himself, herself or themselves in determining to recommend that shareholders vote for the proposals. See the section entitled “Interests of BCSA’s Directors and Officers” below for a further discussion.

PROPOSAL NO. 2 — THE REDEMPTION LIMITATION AMENDMENT PROPOSAL

Overview

BCSA is proposing to amend its Governing Documents to eliminate the limitation that BCSA may not redeem public shares in an amount that would cause BCSA’s net tangible assets to be less than $5,000,001 either immediately prior to or upon consummation of a business combination. A copy of the proposed amendment to our Governing Documents is attached to this proxy statement as Annex B.

Reasons for the Redemption Limitation Amendment Proposal

In the judgment of the Board, adoption of the Redemption Limitation Amendment Proposal may facilitate the consummation of an initial business combination. The Governing Documents limit BCSA’s ability to consummate an initial business combination, or to redeem public shares in connection with an initial business combination, if it would cause BCSA to have less than $5,000,001 in net tangible assets immediately prior to or upon consummation of such business combination.

The initial purpose of the Redemption Limitation requirements was to ensure that BCSA will not be subject to the “penny stock” rules of the SEC as long as it met the Redemption Limitation requirement, and therefore not be deemed a “blank check company” as defined under Rule 419 of the Securities Act because it complied with Rule 3a51-1(g)(1) (the “NTA Rule”). The NTA Rule is one of several exclusions from the “penny stock” rules of the SEC and BCSA believes that it can rely on another exclusion, which relates to it being listed on Nasdaq (Rule 3a51-1(a)(2)) (the “Exchange Rule”). Therefore, BCSA intends to rely on the exclusion from the penny stock rules set forth in Rule 3a51-1(a)(2) as a result of its securities being listed on Nasdaq.

As disclosed in BCSA’s IPO prospectus, because the net proceeds of BCSA’s IPO were being used to complete an initial business combination with a target business that had not been selected at the time of the IPO, BCSA may be deemed a “blank check company.” Under Rule 419 of the Securities Act the term “blank check company” means a company that (i) is a development stage company that has no specific business plan or purpose or has indicated that its business plan is to engage in a merger or acquisition with an unidentified company or companies, or other entity or person; and (ii) is issuing “penny stock,” as defined in Rule 3a51-1 under the Exchange Act. Rule 3a51-1 sets forth that that term “penny stock” shall mean any equity security, unless it fits within certain enumerated exclusions including the NTA Rule and the Exchange Rule. Historically special purpose acquisition companies like BCSA have relied upon the NTA Rule to avoid being deemed a penny stock issuer. The inclusion of the language in the Governing Documents was to ensure that through the consummation of an initial business combination, BCSA would not be considered a penny stock issuer and therefore a blank check company if no other exemption from the rule was available.

The Exchange Rule excludes from the definition of “penny stock” a security that is registered, or approved for registration upon notice of issuance, on a national securities exchange that has been continuously registered as such since Aril 20, 1992 and that has established quantitative listing standards that meet or exceed the criteria in the rule. The Company’s securities are listed on Nasdaq and have been since the consummation of its IPO. The Company believes that Nasdaq has initial listing standards that meet the criteria identified in the Exchange Rule and that it can therefore rely on this rule to avoid being treated as a penny stock. Therefore, the inclusion of the Redemption Limitation is unnecessary.

The Board believes that it is advisable for us to be allowed to effect redemptions and proceed with the Extension and to consummate an initial business combination irrespective of the Redemption Limitation.

If the Redemption Limitation Amendment Proposal is Approved

If the Redemption Limitation Amendment Proposal is approved, the Redemption Limitation Amendment will be effective immediately upon such approval (provided that the Extension Amendment Proposal and Founder Share Amendment are also approved) and we will file the amendment to BCSA’s Governing Documents with the Registrar of Companies of the Cayman Islands in the form of Annex B hereto. We will remain a reporting company under the Exchange Act, and our units, public shares, and public warrants will remain publicly traded.

If the Redemption Limitation Amendment Proposal is Not Approved

The Articles Amendment Proposals are essential to the overall implementation of the Board’s plan to extend the date that we have to complete an initial business combination. Each of the Redemption Limitation Amendment Proposal and Extension Amendment Proposal is cross-conditioned on the approval of each other. None of the Articles Amendment Proposals will be approved if the Redemption Limitation Amendment Proposal is not approved. If none of the Articles Amendment Proposals are approved, we may not be able to consummate an initial business combination within the prescribed time period in the Governing Documents and may be required to liquidate as described elsewhere in this proxy statement.

Required Vote

Approval of the Redemption Limitation Amendment Proposal will require a special resolution under Cayman Islands law, being the affirmative vote of at least a two-thirds (2/3) majority of the votes cast by the holders of the issued ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter, including those shares held as a constituent part of our units, on the record date.

In addition, approval of the Redemption Limitation Amendment Proposal is cross-conditioned on the approval of the Extension Amendment Proposal and Founder Share Amendment Proposal.

PROPOSAL NO. 3 — THE FOUNDER SHARE AMENDMENT PROPOSAL

Overview

BCSA is proposing to amend its Governing Documents to permit for the issuance of Class A ordinary shares to holders of Class B ordinary shares upon the exercise of the right of a holder of Class B ordinary shares to convert such holder’s Class B ordinary shares into Class A ordinary shares on a one-for-one basis at any time and from time to time prior to the closing an initial business combination at the election of the holder. A copy of the proposed amendment to our Governing Documents is attached to this proxy statement as Annex C.

The Founder Share Amendment requires that holders of Class B ordinary shares electing to convert those shares waive their rights to receive funds from the trust account in connection with any subsequent redemption of the Class A ordinary shares issuable upon such conversion or otherwise. Holders of Class B ordinary shares have already waived any such rights with respect to their Class B ordinary shares when they entered into the Letter Agreement in connection with the IPO.

Reasons for the Founder Share Amendment Proposal

The purpose of the Founder Share Amendment Proposal is to provide the holders of Class B ordinary shares with the flexibility to assist BCSA in meeting the listing requirements of its Class A ordinary shares if necessary or desirable in connection with the Extension and the consummation of an initial business combination. This flexibility may also assist BCSA in retaining investors. Notwithstanding conversion of Class B ordinary shares into Class A ordinary shares, the holders of such converted shares have already waived their rights and will not be entitled to receive any monies held in the trust account as a result of its ownership of any Class A ordinary shares.

If in connection with approval of the Articles Amendment Proposals or our initial business combination there are significant requests for redemption such that upon completing the redemptions we no longer satisfy the listing criteria set forth in Nasdaq Listing Rule 5450, the Founder Share Amendment Proposal will provide an avenue for regaining compliance. The Class B ordinary shares held by our initial shareholders do not currently count toward the calculations of market value or number of publicly held shares under Nasdaq Listing Rule 5450, but the Class A ordinary shares issuable upon conversion of such Class B ordinary shares may.

If the Founder Share Amendment Proposal is Approved

If the Founder Share Amendment Proposal is approved, the Founder Share Amendment will be effective immediately upon such approval (provided that the Extension Amendment Proposal and Redemption Limitation Amendment Proposal are also approved) and we will file the amendment to BCSA’s Governing Documents with the Registrar of Companies of the Cayman Islands in the form of Annex C. We will remain a reporting company under the Exchange Act, and our units, public shares, and public warrants will remain publicly traded.

We expect that if the Articles Amendment Proposals are approved, the Sponsor and BCSA’s independent directors, as the sole holders of Class B ordinary shares, will elect to convert some or all of their Class B ordinary shares to Class A ordinary shares, on a one-for-one basis, in accordance with the Governing Documents. The Class B Conversion would be effected prior to the redemption of any public shares in connection with such approval and could result in up to an additional 10,000,000 Class A ordinary shares outstanding. Notwithstanding the Class B Conversion, the Sponsor and BCSA’s independent directors will not be entitled to receive any funds held in the trust account with respect to any Class A ordinary shares issued to them as a result of the Class B Conversion and no additional amounts will be deposited into the trust account in respect of any such Class A ordinary shares.

If the Founder Share Amendment Proposal is Not Approved

If the Founder Share Amendment Proposal is not approved, the holders of Class B ordinary shares may not be able to convert Class B ordinary shares to Class A ordinary shares prior to the completion of an initial business combination. We believe this inability may reduce our flexibility to maintain a listing of Class A ordinary shares on Nasdaq when redemptions are completed in connection with approval of the Articles Amendment Proposals and our initial business combination.

In addition, each of the Founder Share Amendment Proposal and Extension Amendment Proposal is cross-conditioned on the approval of each other. None of the Articles Amendment Proposals will be approved if the Founder Share Amendment Proposal is not approved. If none of the Articles Amendment Proposals are approved, we may not be able to consummate an initial business combination within the prescribed time period in the Governing Documents and may be required to liquidate as described elsewhere in this proxy statement.

PROPOSAL NO. 4 — THE ADJOURNMENT PROPOSAL

Overview

The Adjournment Proposal, if adopted, will allow our Board to adjourn the Extraordinary General Meeting to a later date or dates, if necessary or appropriate, either (x) to permit further solicitation and vote of proxies in the event that there are insufficient votes to approve any of the Articles Amendment Proposals or if BCSA determines that it is otherwise necessary or (y) if the Board determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.

We do not expect to present the Adjournment Proposal to our shareholders unless there are insufficient votes to approve one or more of the Articles Amendment Proposals at the Extraordinary General Meeting or the Board otherwise determines adjournment is necessary or determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.

If the Adjournment Proposal is Not Approved

If the Adjournment Proposal is not approved by our shareholders, our Board may not be able to adjourn the Extraordinary General Meeting to a later date in the event that there are insufficient votes to approve one or more of the Articles Amendment Proposals at the Extraordinary General Meeting or the Board otherwise determines adjournment is necessary or determines before the Extraordinary General Meeting that it is not necessary or no longer desirable to proceed with the Articles Amendment Proposals.

Required Vote

The approval of the Adjournment Proposal requires the affirmative vote of a simple majority of the votes cast by the holders of the issued ordinary shares present in person (including via live webcast) or represented by proxy at the Extraordinary General Meeting and entitled to vote on such matter.

Recommendation

As discussed above, after careful consideration of all relevant factors, our Board has determined that the Adjournment Proposal is in the best interests of BCSA and its shareholders. Our Board has approved and recommends adoption of the Adjournment Proposal.

OUR BOARD RECOMMENDS THAT YOU VOTE “FOR” THE ADJOURNMENT PROPOSAL.

REDEMPTION RIGHTS

In connection with the approval of the Articles Amendment Proposals at the Extraordinary General Meeting, any holder of public shares may seek to redeem all or a portion of their public shares at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account as of two business days prior to such approval, including any interest earned on the trust account deposits (which interest shall be net of taxes payable), divided by the number of then outstanding public shares. However, a public shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13(d)(3) of the Exchange Act), will be restricted from seeking redemption rights with respect to more than an aggregate of 15% of the Class A ordinary shares without the prior consent of BCSA.

Following approval of the Articles Amendment Proposals, the Withdrawal Amount will be withdrawn from the trust account and paid to the redeeming public shareholders with respect to the portion of public shares that were validly redeemed as described above. In addition, the remaining public shareholders will be entitled to have their shares redeemed for cash if we have not completed a business combination by the Extended Date, subject to any limitations set forth in our Governing Documents.

TO EXERCISE YOUR REDEMPTION RIGHTS, YOU MUST ENSURE YOUR BANK OR BROKER COMPLIES WITH THE REQUIREMENTS IDENTIFIED HEREIN, INCLUDING SUBMITTING A WRITTEN REQUEST THAT YOUR SHARES BE REDEEMED FOR CASH TO THE TRANSFER AGENT AND DELIVERING YOUR SHARES TO THE TRANSFER AGENT PRIOR TO 5:00 P.M. ET ON SEPTEMBER [ ], 2023 (TWO BUSINESS DAYS BEFORE THE SCHEDULED VOTE AT THE EXTRAORDINARY GENERAL MEETING). YOU WILL ONLY BE ENTITLED TO RECEIVE CASH IN CONNECTION WITH A REDEMPTION OF THESE SHARES IF YOU CONTINUE TO HOLD THEM UNTIL THE EFFECTIVE TIME OF THE ARTICLES AMENDMENT PROPOSALS.

Pursuant to our Governing Documents, a public shareholder may request that BCSA redeem all or a portion of such public shareholder’s public shares for cash if the Extension Amendment Proposal is approved. You will be entitled to receive cash for any public shares to be redeemed only if you:

(i) (a) hold public shares or (b) hold public shares through units and you elect to separate your units into the underlying public shares and public warrants prior to exercising your redemption rights with respect to the public shares; and

(ii) prior to 5:00 p.m. Eastern Time, on September [ ], 2023 (two business days prior to the scheduled vote at the Extraordinary General Meeting), (a) submit a written request, including the name, phone number, and address of the beneficial owner of the shares for which redemption is requested, to Continental Stock Transfer & Trust Company, BCSA’s transfer agent, at Continental Stock Transfer & Trust Company, 1 State Street, 30th Floor, New York, New York 10004, Attn: Mark Zimkind (e-mail: mzimkind@continentalstock.com), that BCSA redeem your public shares for cash and (b) tender or deliver your shares (and share certificates (if any) and other redemption forms) to the transfer agent, physically or electronically through DTC.

Holders of units must elect to separate the underlying public shares and public warrants prior to exercising redemption rights with respect to the public shares. If holders hold their units in an account at a brokerage firm or bank, holders must notify their broker or bank that they elect to separate the units into the underlying public shares and public warrants, or if a holder holds units registered in its own name, the holder must contact the transfer agent directly and instruct it to do so. Subject to the limitations set forth above, public shareholders may elect to redeem all or a portion of their public shares regardless of whether they vote for or against the Articles Amendment Proposals and regardless of whether they hold public shares on the record date.

Table of Contents

the broker would determine whether or not to pass this cost on to the redeeming holder. It is our understanding that shareholders should generally allot at least two weeks to obtain physical certificates from the transfer agent. We do not have any control over this process or over the brokers or DTC, and it may take longer than two weeks to obtain a physical share certificate. Such shareholders will have less time to make their investment decision than those shareholders that deliver their shares through the DWAC system. Shareholders who request physical share certificates and wish to redeem may be unable to meet the deadline for tendering their shares before exercising their redemption rights and thus will be unable to redeem their shares.

Certificates that have not been tendered in accordance with these procedures prior to the vote on the Articles Amendment Proposals will not be redeemed for cash held in the trust account on the redemption date. In the event that a public shareholder tenders its shares and decides prior to the vote at the Extraordinary General Meeting that it does not want to redeem its shares, the shareholder may withdraw the tender with the consent of the Board. If you delivered your shares for redemption to our transfer agent and decide prior to the vote at the Extraordinary General Meeting not to redeem your public shares, you may request that our transfer agent return the shares (physically or electronically). You may make such request by contacting our transfer agent at the address listed above. In the event that a public shareholder tenders shares and the Articles Amendment Proposals are not approved, these shares will not be redeemed and the physical certificates representing these shares will be returned to the shareholder promptly following the determination that the Articles Amendment Proposals will not be approved. We anticipate that a public shareholder who tenders shares for redemption in connection with the vote to approve the Articles Amendment Proposals would receive payment of the redemption price for such shares soon after approval of such proposals. The transfer agent will hold the certificates of public shareholders that make the election until such shares are redeemed for cash or returned to such shareholders.

If properly demanded, we will redeem each public share for a per-share price, payable in cash, equal to the aggregate amount then on deposit in the trust account, including any interest earned on the funds held in the trust account and not previously released to us to pay our franchise and income taxes, divided by the total number of then outstanding public shares. Based on the amount in the trust account as of the record date, this would amount to approximately $[ ] per share, which amount includes interest earned on the funds held in the trust account and not previously or yet released to BCSA to pay its taxes. The closing price of the ordinary shares on Nasdaq on August 29, 2023, the record date, was $[ ]. BCSA cannot assure public shareholders that they will be able to sell their public shares in the open market, even if the market price per share is higher than the redemption price stated above, as there may not be sufficient liquidity in its securities when such shareholders wish to sell their shares.

If you exercise your redemption rights, you will be exchanging your shares of BCSA’s ordinary shares for cash and will no longer own the shares. You will be entitled to receive cash for these shares only if you properly demand redemption and tender your share certificate(s) to BCSA’s transfer agent prior to 5:00 p.m. Eastern Time on September [ ], 2023 (two business days before the scheduled vote at the Extraordinary General Meeting).

INTERESTS OF BCSA’S DIRECTORS AND EXECUTIVE OFFICERS

When you consider the recommendation of our Board, you should keep in mind that BCSA’s executive officers and directors, and their affiliates, have interests that may be different from, or in addition to, your interests as a shareholder. These interests include, among other things:

• If the Articles Amendment Proposals are not approved and BCSA does not consummate an initial business combination by the Current Outside Date, in accordance with our Governing Documents, the 10,000,000 founder shares, which were acquired by our initial shareholders prior to our IPO for an aggregate investment of $25,000, or approximately $0.003 per share, will be worthless (as the initial shareholders have waived liquidation rights with respect to such shares). The founder shares had an aggregate market value of approximately $[ ] based on the last sale price of the public shares of $[ ] on Nasdaq on August 29, 2023 (the record date);

• If the Articles Amendment Proposals are not approved and BCSA does not consummate an initial business combination by the Current Outside Date, in accordance with the terms of the purchase agreement governing the private placement units, the 1,322,000 private placement units purchased by our Sponsor for an aggregate investment of $13,220,000, or $10.00 per private placement unit, will be worthless, as they will expire. The private placement units had an aggregate market value of $[ ] based on the last sale price of the units of $[ ] on Nasdaq on August 29, 2023 (the record date);

• Even if the trading price of the Class A ordinary shares were as low as $1.17 per share, the aggregate market value of the founder shares and the Class A ordinary shares contained in the private placement units held by the Sponsor (without taking into account the value of the private placement warrants) would be approximately equal to the initial investment in BCSA by our Sponsor. As a result, if an initial business combination is completed, the initial shareholders are likely to be able to make a substantial profit on their investment in us even at a time when the Class A ordinary shares have lost significant value. On the other hand, if the Articles Amendment Proposals are not approved and BCSA liquidates without completing its initial business combination before November 15, 2023, the initial shareholders will lose their entire investment in us, including the $25,000 purchase price for the founder shares and the $13,220,000 purchase price for the private placement units.

• The Sponsor has agreed that it will be liable to us if and to the extent any claims by a third party (other than our registered public accounting firm) for services rendered or products sold to us, or a prospective target business with which we have discussed entering into a transaction agreement, reduce the amounts in the trust account to below the lesser of (i) $10.20 per public share and (ii) the actual amount per public share held in the trust account as of the date of the liquidation of the trust account if less than $10.20 per public share due to reductions in the value of the trust assets, in each case net of the interest that may be withdrawn to pay our tax obligations, provided that such liability will not apply to any claims by a third-party or prospective target business that executed a waiver of any and all rights to seek access to the trust account nor will it apply to any claims under our indemnity of the underwriters of this offering against certain liabilities, including liabilities under the Securities Act;

• All rights specified in the Governing Documents relating to the right of officers and directors to be indemnified by BCSA, and of BCSA’s executive officers and directors to be exculpated from monetary liability with respect to prior acts or omissions, will continue after a business combination. If a business combination is not approved and BCSA liquidates, BCSA will not be able to perform its obligations to its officers and directors under those provisions;

• All of the current members of our Board are expected to continue to serve as directors at least through the date of the Extraordinary General Meeting to approve a business combination and at least one is expected to continue to serve following a business combination and receive compensation thereafter; and

Table of Contents

• BCSA’s executive officers and directors, and their affiliates are entitled to reimbursement of out-of-pocket expenses incurred by them in connection with certain activities on BCSA’s behalf, such as identifying and investigating possible business targets and business combinations. However, if BCSA fails to obtain approval of the Articles Amendment Proposals and consummate a business combination, they will not have any claim against the trust account for reimbursement. Accordingly, BCSA may not be able to reimburse these expenses if a business combination is not completed.

Additionally, if the Articles Amendment Proposals are approved and we consummate an initial business combination, our Sponsor, officers and directors may have additional interests as will be described in the proxy statement for the business combination.

U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following discussion summarizes certain U.S. federal income tax considerations generally applicable to U.S. Holders (as defined below) and Non-U.S. Holders (as defined below) (i) of the Articles Amendment Proposals and (ii) that elect to have their public shares redeemed for cash if the Articles Amendment Proposals are approved. This discussion assumes that the public shares and public warrants are treated as separate instruments for U.S. federal income tax purposes. Accordingly, the separation of units into the public shares and public warrants underlying the units generally should not be a taxable event for U.S. federal income tax purposes. This position is not free from doubt, and no assurance can be given that the U.S. Internal Revenue Service (“IRS”) would not assert, or that a court would not sustain, a contrary position. Holders of units are urged to consult their tax advisors concerning the U.S. federal, state, local and non-U.S. tax consequences of the transactions contemplated by the Extension Amendment (including any redemption of the public shares in connection therewith) with respect to any public shares held through the units (including alternative characterizations of the units).

This discussion is limited to certain U.S. federal income tax considerations to beneficial owners of our public shares who hold their public shares as a capital asset under the U.S. Internal Revenue Code of 1986, as amended (the “Code”). This discussion does not address any aspect of state, local or non-U.S. taxation, or any U.S. federal taxes other than income taxes (such as gift and estate taxes). This discussion is a summary only and does not consider all aspects of U.S. federal income taxation that may be relevant to you in light of your particular circumstances, including the alternative minimum tax, the Medicare tax on net investment income and the different consequences that may apply to you if you are subject to special rules that apply to certain types of investors, such as:

• our sponsor, officers or directors;

• banks, financial institutions or financial services entities;

• broker-dealers;

• taxpayers that are subject to the mark-to-market method of accounting rules;

• tax-exempt entities;

• S-corporations;

• governments or agencies or instrumentalities thereof;

• insurance companies;

• regulated investment companies;

• real estate investment trusts;

• expatriates or former long-term residents of the United States;

• persons that actually or constructively own 5% or more of our public shares (by vote or value);

• persons that acquired our public shares pursuant to an exercise of employee share options, in connection with employee share incentive plans or otherwise as compensation or in connection with services

• persons required for U.S. federal income tax purposes to conform the timing of income accruals to their financial statements under Section 451 of the Code;

• persons that hold our public shares as part of a straddle, constructive sale, hedging, wash sale, conversion or other integrated or similar transaction; or

• U.S. Holders (as defined below) whose functional currency is not the U.S. dollar.

Moreover, the discussion below is based upon the provisions of the Code, the Treasury regulations promulgated thereunder and administrative and judicial interpretations thereof, all as of the date hereof. Those authorities may be repealed, revoked, modified or subject to differing interpretations, possibly on a retroactive basis, so as to result in U.S. federal income tax consequences different from those discussed below.

Table of Contents

We have not sought, and will not seek, a ruling from the IRS as to any U.S. federal income tax consequence described herein. The IRS may disagree with the discussion herein, and its determination may be upheld by a court. Moreover, there can be no assurance that future legislation, regulations, administrative rulings or court decisions will not affect the accuracy of the statements in this discussion.

As used herein, the term “U.S. Holder” means a beneficial owner of units or public shares that is for U.S. federal income tax purposes:

• an individual citizen or resident of the United States;

• a corporation (or other entity treated as a corporation for U.S. federal income tax purposes) that is created or organized (or treated as created or organized) in or under the laws of the United States, any state thereof or the District of Columbia;

• an estate the income of which is subject to U.S. federal income taxation regardless of its source; or

• a trust if (A) a court within the United States is able to exercise primary supervision over the administration of the trust and one or more U.S. persons have the authority to control all substantial decisions of the trust, or (B) it has in effect under applicable U.S. Treasury regulations a valid election to be treated as a U.S. person.

This discussion does not consider the tax treatment of partnerships (or other pass-through entities or arrangements classified as a partnership for U.S. federal income tax purposes) or persons who hold our public shares through such entities. If a partnership (or other entity or arrangement classified as a partnership for U.S. federal income tax purposes) is the beneficial owner of our public shares, the U.S. federal income tax treatment of a partner in the partnership (or other owner in a pass-through entity) generally will depend on the status of the partner (or other owner) and the activities of the partner (or other owner) and the partnership (or other pass-through entity). If you are a partner of a partnership holding our public shares, we urge you to consult your own tax advisor.

THIS DISCUSSION IS FOR INFORMATIONAL PURPOSES ONLY, IS ONLY A SUMMARY OF CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS ASSOCIATED WITH THE ACQUISITION, OWNERSHIP, AND DISPOSITION OF OUR SECURITIES, INCLUDING THE EFFECTS OF OUR DOMESTICATION AND IS NOT A SUBSTITUTE FOR CAREFUL TAX PLANNING. EACH PROSPECTIVE INVESTOR IN OUR SECURITIES IS URGED TO CONSULT ITS TAX ADVISOR WITH RESPECT TO THE PARTICULAR TAX CONSEQUENCES TO SUCH INVESTOR OF THE ACQUISITION, OWNERSHIP AND DISPOSITION OF OUR SECURITIES, INCLUDING THE APPLICABILITY AND EFFECT OF U.S. FEDERAL, STATE, LOCAL, AND NON-UNITED STATES TAX LAWS, AS WELL AS UNDER ANY APPLICABLE TAX TREATY.

Tax Treatment of Non-Redeeming Shareholders

A public shareholder who does not elect to redeem their public shares in connection with the approval of the Articles Amendment Proposals will continue to own its public shares, and will not recognize any income, gain or loss for U.S. federal income tax purposes solely as a result of the Articles Amendment Proposals.

U.S. Holders

Generally

Subject to the PFIC rules discussed below, the U.S. federal income tax consequences to a U.S. Holder of public shares that exercises its redemption rights with respect to its public shares to receive cash in exchange for all or a portion of its public shares will depend on whether it qualifies as a sale or exchange of the public shares under Section 302 of the Code. If the redemption qualifies as a sale or exchange of public shares, the U.S. Holder will be treated as described below under “— Taxation of Redemption Treated as Gain or Loss on Sale of Public Shares.” If the redemption does not qualify as a sale or exchange of public shares, the U.S. Holder will be treated as receiving a corporate distribution with the tax consequences described below under “— Taxation of Redemption Treated as a Distribution.” Whether a redemption qualifies for sale or exchange treatment will depend largely on the total number of our public shares treated as held by the U.S. Holder (including any public shares constructively owned by the U.S. Holder described in the following paragraph) relative to all of our public shares outstanding both before and after such redemption. The redemption of public shares generally will be treated as a sale or exchange of the public

shares (rather than as a corporate distribution) if, within the meaning of Section 302 of the Code, such redemption (i) is “substantially disproportionate” with respect to the U.S. Holder, (ii) results in a “complete termination” of the U.S. Holder’s interest in us or (iii) is “not essentially equivalent to a dividend” with respect to the U.S. Holder. These tests are explained more fully below.

In determining whether any of the foregoing tests are satisfied, a U.S. Holder takes into account not only our public shares actually owned by the U.S. Holder, but also our public shares that are constructively owned by it. A U.S. Holder may constructively own, in addition to public shares owned directly, public shares owned by certain related individuals and entities in which the U.S. Holder has an interest or that have an interest in such U.S. Holder, as well as any public shares the U.S. Holder has a right to acquire by exercise of an option, which generally would include public shares which could be acquired pursuant to the exercise of the public warrants. In order to meet the substantially disproportionate test, the percentage of our outstanding voting shares actually and constructively owned by the U.S. Holder immediately following the redemption of public shares must, among other requirements, be less than 80% of the percentage of our outstanding voting shares actually and constructively owned by the U.S. Holder immediately before the redemption. Prior to our initial business combination, the public shares may not be treated as voting shares for this purpose and, consequently, this substantially disproportionate test may not be applicable. There will be a complete termination of a U.S. Holder’s interest if either (i) all of our shares actually and constructively owned by the U.S. Holder are redeemed or (ii) all of our shares actually owned by the U.S. Holder are redeemed and the U.S. Holder is eligible to waive, and effectively waives in accordance with specific rules, the attribution of shares owned by certain family members and the U.S. Holder does not constructively own any other of our shares. The redemption of the public shares will not be essentially equivalent to a dividend with respect to a U.S. Holder if it results in a “meaningful reduction” of the U.S. Holder’s proportionate interest in us. Whether the redemption will result in a meaningful reduction in a U.S. Holder’s proportionate interest in us will depend on the particular facts and circumstances.

However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation who exercises no control over corporate affairs may constitute such a “meaningful reduction.” However, the IRS has indicated in a published ruling that even a small reduction in the proportionate interest of a small minority shareholder in a publicly held corporation where such shareholder exercises no control over corporate affairs may constitute such a “meaningful reduction. A U.S. Holder should consult with its tax advisors as to the tax consequences of a redemption of any public shares.

If none of the foregoing tests are satisfied, then the redemption will be treated as a corporate distribution and the tax effects will be as described below under “— Taxation of Redemption Treated as a Distribution.” After the application of those rules, any remaining tax basis of the U.S. Holder in the redeemed public shares will be added to the U.S. Holder’s adjusted tax basis in its remaining shares, or, if it has none, to the U.S. Holder’s adjusted tax basis in its public warrants or possibly in other shares constructively owned by it.

U.S. Holders who actually or constructively own five or more of our shares (by vote or value) may be subject to special reporting requirements with respect to a redemption of public shares, and such holders should consult with their tax advisors with respect to their reporting requirements.

Taxation of Redemption Treated as Gain or Loss on Sale of Public Shares

Subject to the PFIC rules discussed below, if the redemption of a U.S. Holder’s public shares is treated as a sale, as discussed above under the section entitled “— Generally,” a U.S. Holder generally will recognize capital gain or loss equal to the difference between (i) the sum of the amount of cash received in the redemption and (ii) the U.S. Holder’s adjusted tax basis in its public shares surrendered in the redemption. Any such capital gain or loss generally will be long-term capital gain or loss if the U.S. Holder’s holding period for such public shares exceeds one year. Long-term capital gain realized by a non-corporate U.S. Holder currently is subject to reduced tax rates. It is unclear, however, whether certain redemption rights described in this proxy statement may suspend the running of the applicable holding period for this purpose. The deduction of capital losses is subject to certain limitations.

Taxation of Redemption Treated as a Distribution

Subject to the PFIC rules discussed below, if the redemption of a U.S. Holder’s public shares is treated as a distribution, as discussed above under the section entitled “— Generally,” a U.S. Holder generally will be required to include in gross income, in accordance with such U.S. Holder’s method of accounting for U.S. federal income tax purposes, as dividends the amount of the cash received in the redemption to the extent paid out of our current

Table of Contents

or accumulated earnings and profits (as determined under U.S. federal income tax principles). The amount of any such dividends generally will be treated as foreign source dividend income for U.S. federal income tax purposes. The amount of any such dividends paid by us will be taxable to a corporate U.S. Holder at regular rates and will not be eligible for the dividends-received deduction generally allowed to domestic corporations in respect of dividends received from other domestic corporations. Cash received in the redemption in excess of such earnings and profits generally will be applied against and reduce the U.S. Holder’s basis in its public shares (but not below zero) and, to the extent in excess of such basis, will be treated as gain from the sale or exchange of such public shares (see “— Taxation of Redemption Treated as Gain or Loss on Sale of Public Shares” above).

With respect to non-corporate U.S. Holders, under tax laws currently in effect and subject to certain exceptions (including, but not limited to, dividends treated as investment income for purposes of investment interest deduction limitations), dividends generally will be taxed at the lower applicable long-term capital gains rate (see “— Taxation of Redemption Treated as Gain or Loss on Sale of Public Shares” above) only if our public shares are readily tradable on an established public shares market in the United States and certain other requirements, including certain holding period requirements, are met. It is unclear, however, whether certain redemption rights described in this proxy statement may suspend the running of the applicable holding period for this purpose. In addition, if we are treated as a PFIC, our dividends will not qualify for this lower applicable long-term capital gains rate. U.S. Holders should consult their tax advisors regarding the availability of such lower rate for any amounts treated as dividends paid with respect to our public shares in the redemption.

Passive Foreign Investment Company Rules

A foreign (i.e., non-U.S.) corporation will be classified as a PFIC for U.S. federal income tax purposes if either (i) at least 75% of its gross income in a taxable year, including its pro rata share of the gross income of any corporation in which it is considered to own at least 25% of the shares by value, is passive income or (ii) at least 50% of its assets in a taxable year (ordinarily determined based on fair market value and averaged quarterly over the year), including its pro rata share of the assets of any corporation in which it is considered to own at least 25% of the shares by value, are held for the production of, or produce, passive income. Passive income generally includes dividends, interest, rents and royalties (other than rents or royalties derived from the active conduct of a trade or business) and gains from the disposition of passive assets.

Because we are a blank check company, with no current active business, we believe we have met the PFIC asset or income test beginning with our initial, 2021, taxable year. Pursuant to a start-up exception, however, a foreign corporation will not be a PFIC for the first taxable year the corporation has gross income, if (1) no predecessor of the corporation was a PFIC; (2) the corporation satisfies the IRS that it will not be a PFIC for either of the two taxable years following the start-up year; and (3) the corporation is not in fact a PFIC for either of those years (the “start-up exception”). However, based upon the composition of our income and assets, and our expectations regarding the timing of the completion of the Proposed Business Combination, we believe we will not be eligible for the start-up exception and therefore that we have been a PFIC since our first taxable year.

If we are determined to be a PFIC for any taxable year (or portion thereof) that is included in the holding period of a U.S. Holder of our public shares and the U.S. Holder did not make either a qualified electing fund (“QEF”) election for our first taxable year as a PFIC in which the U.S. Holder held (or was deemed to hold) public shares, a QEF election along with a purging election, or a mark-to-market election, each as described below, such U.S. Holder generally will be subject to special rules with respect to (i) any gain recognized by the U.S. Holder on the sale of its public shares in the redemption and (ii) any “excess distribution” made to the U.S. Holder (generally, any distributions to such U.S. Holder during a taxable year of the U.S. Holder that are greater than 125% of the average annual distributions received by such U.S. Holder in respect of the public shares during the three preceding taxable years of such U.S. Holder or, if shorter, such U.S. Holder’s holding period for the public shares).

Under these rules:

• the U.S. Holder’s gain or excess distribution will be allocated ratably over the U.S. Holder’s holding period for the public shares;

• the amount allocated to the U.S. Holder’s taxable year in which the U.S. Holder recognized the gain or received the excess distribution, or to the period in the U.S. Holder’s holding period before the first day of our first taxable year in which we are a PFIC, will be taxed as ordinary income;

Table of Contents

• the amount allocated to other taxable years (or portions thereof) of the U.S. Holder and included in its holding period will be taxed at the highest tax rate in effect for that year and applicable to the U.S. Holder; and

• an additional tax equal to the interest charge generally applicable to underpayments of tax will be imposed on the U.S. Holder with respect to the tax attributable to each such other taxable year of the U.S. Holder.

In general, if we are determined to be a PFIC, a U.S. Holder will avoid the PFIC tax consequences described above in respect of our public shares by making a timely and valid QEF election (if eligible to do so) to include in income its pro rata share of our net capital gains (as long-term capital gain) and other earnings and profits (as ordinary income), on a current basis, in each case whether or not distributed, in the taxable year of the U.S. Holder in which or with which our taxable year ends. A U.S. Holder generally may make a separate election to defer the payment of taxes on undistributed income inclusions under the QEF rules, but if deferred, any such taxes will be subject to an interest charge.

The QEF election is made on a shareholder-by-shareholder basis and, once made, can be revoked only with the consent of the IRS. A U.S. Holder generally makes a QEF election by attaching a completed IRS Form 8621 (Information Return by a Shareholder of a Passive Foreign Investment Company or Qualified Electing Fund), including the information provided in a PFIC Annual Information Statement, to a timely filed U.S. federal income tax return for the tax year to which the election relates. Retroactive QEF elections generally may be made only by filing a protective statement with such return and if certain other conditions are met or with the consent of the IRS. U.S. Holders should consult their tax advisors regarding the availability and tax consequences of a retroactive QEF election under their particular circumstances.

In order to comply with the requirements of a QEF election, a U.S. Holder must receive a PFIC Annual Information Statement from us. If we determine we are a PFIC for any taxable year we will endeavor to provide, upon written request, to a U.S. Holder such information as the IRS may require, including a PFIC Annual Information Statement, in order to enable the U.S. Holder to make and maintain a QEF election, but there is no assurance that we will timely provide such required information. There is also no assurance that we will have timely knowledge of our status as a PFIC in the future or of the required information to be provided.

If a U.S. Holder has made a QEF election with respect to our public shares, and the excess distribution rules discussed above do not apply to such shares (because of a timely QEF election for our first taxable year as a PFIC in which the U.S. Holder holds (or is deemed to hold) such shares or a purge of the PFIC taint pursuant to a purging election, as described above), any gain recognized on the sale of our public shares in the redemption generally will be taxable as capital gain and no additional tax or interest charge will be imposed under the PFIC rules. As discussed above, if we are a PFIC for any taxable year, a U.S. Holder of our public shares that has made a QEF election will be taxed currently on its pro rata share of our earnings and profits, whether or not distributed for such year. A subsequent distribution of such earnings and profits that were previously included in income generally should not be taxable when distributed to such U.S. Holder. The tax basis of a U.S. Holder’s public shares in a QEF will be increased by amounts that are included in income, and decreased by amounts distributed but not taxed as dividends, under the above rules. Similar basis adjustments apply to property if, by reason of holding such property, the U.S. Holder is treated under the applicable attribution rules as owning shares in a QEF. In addition, if we are not a PFIC for any taxable year, such U.S. Holder will not be subject to the QEF inclusion regime with respect to our public shares for such taxable year.

Alternatively, if we are a PFIC and our public shares constitute “marketable stock,” a U.S. Holder may avoid the adverse PFIC tax consequences discussed above if such U.S. Holder, at the close of the first taxable year in which it holds (or is deemed to hold) our public shares, makes a mark-to-market election with respect to such shares for such taxable year. Such U.S. Holder generally will include for each of its taxable years as ordinary income the excess, if any, of the fair market value of its public shares at the end of such year over its adjusted basis in its public shares. These amounts of ordinary income would not be eligible for the favorable tax rates applicable to qualified dividend income or long-term capital gains. The U.S. Holder also will recognize an ordinary loss in respect of the excess, if any, of its adjusted basis of its public shares over the fair market value of its public shares at the end of its taxable year (but only to the extent of the net amount of previously included income as a result of the mark-to-market election). The U.S. Holder’s basis in its public shares will be adjusted to reflect any such income or loss amounts, and any further gain recognized on a sale or other taxable disposition of its public shares will be treated as ordinary income.

Table of Contents

The mark-to-market election is available only for “marketable stock,” generally, stock that is regularly traded on a national securities exchange that is registered with the Securities and Exchange Commission, including Nasdaq (on which our public shares are listed), or on a foreign exchange or market that the IRS determines has rules sufficient to ensure that the market price represents a legitimate and sound fair market value. If made, a mark-to-market election would be effective for the taxable year for which the election was made and for all subsequent taxable years unless the public shares ceased to qualify as “marketable stock” for purposes of the PFIC rules or the IRS consented to the revocation of the election. U.S. Holders should consult their tax advisors regarding the availability and tax consequences of a mark-to-market election with respect to our public shares under their particular circumstances.

If we are a PFIC and, at any time, have a foreign subsidiary that is classified as a PFIC, U.S. Holders generally would be deemed to own a portion of the shares of such lower-tier PFIC, and generally could incur liability for the deferred tax and interest charge described above if we receive a distribution from, or dispose of all or part of our interest in, the lower-tier PFIC or the U.S. Holders otherwise were deemed to have disposed of an interest in the lower-tier PFIC. We will endeavor to cause any lower-tier PFIC to provide to a U.S. Holder the information that may be required to make or maintain a QEF election with respect to the lower-tier PFIC. There can be no assurance that we will have timely knowledge of the status of any such lower-tier PFIC. In addition, we may not hold a controlling interest in any such lower-tier PFIC and thus there can be no assurance we will be able to cause the lower-tier PFIC to provide such required information. U.S. Holders are urged to consult their tax advisors regarding the tax issues raised by lower-tier PFICs.

A U.S. Holder that owns (or is deemed to own) shares in a PFIC during any taxable year of the U.S. Holder, may have to file an IRS Form 8621 (whether or not a QEF or market-to-market election is made) and such other information as may be required by the U.S. Treasury Department. If a U.S. Holder does not file the required IRS Form 8621, such person may be subject to substantial penalties, and the statute of limitations on the assessment and collection of all U.S. federal income taxes of such person for the related tax year may not close before the date which is three years after the date on which such form is filed.

The rules dealing with PFICs and with the QEF and mark-to-market elections are very complex and are affected by various factors in addition to those described above. Accordingly, U.S. Holders of our public shares should consult their own tax advisors concerning the application of the PFIC rules to our public shares under their particular circumstances.

Tax Reporting

Certain U.S. Holders who are individuals and certain entities generally will be required to report information with respect to such U.S. Holder’s investment in “specified foreign financial assets” on IRS Form 8938 (Statement of Specified Foreign Financial Assets), subject to certain exceptions. Interests in BCSA (including our public shares) constitute specified foreign financial assets for these purposes. Persons who are required to report specified foreign financial assets and fail to do so may be subject to substantial penalties and the period of limitations on assessment and collection of U.S. federal income taxes generally will be extended in the event of a failure to comply. Potential investors are urged to consult their tax advisors regarding the foreign financial asset and other reporting obligations and their application to a redemption of our public shares.

Non-U.S. Holders

This section applies to you if you are a “Non-U.S. Holder.” As used herein, the term “Non-U.S. Holder” means a beneficial owner of our units, public shares (other than a partnership or other entity or arrangement treated as a partnership for U.S. federal income tax purposes) who or that is for U.S. federal income tax purposes:

• a non-resident alien individual (other than certain former citizens and residents of the United States subject to U.S. tax as expatriates);

• a foreign corporation; or

• an estate or trust that is not a U.S. Holder;

but generally does not include an individual who is present in the United States for 183 days or more in the taxable year of the disposition of our units, public shares. If you are such an individual, you should consult your tax advisor regarding the U.S. federal income tax consequences of the of the transactions contemplated by the Extension Amendment (including any redemption of the public shares in connection therewith).

Table of Contents

Generally

The U.S. federal income tax consequences to a Non-U.S. Holder of public shares that exercises its redemption rights with respect to its public shares will depend on whether the redemption qualifies as a sale of the public shares redeemed, as described above under “Tax Treatment of Redeeming Shareholders — U.S. Holders — Generally.” If such a redemption qualifies as a sale of public shares, the U.S. federal income tax consequences to the Non-U.S. Holder will be as described below under “— Taxation of Redemption Treated as a Sale of Public Shares.” If such a redemption does not qualify as a sale of public shares, the Non-U.S. Holder will be treated as receiving a corporate distribution, the U.S. federal income tax consequences of which are described below under “— Taxation of Redemption as a Distribution.”

Taxation of Redemption Treated as a Sale of Public Shares

If the redemption of a U.S. Holder’s public shares is treated as a sale, as described above under “Tax Treatment of Redeeming Shareholders — U.S. Holders — Generally,” a Non-U.S. Holder generally will not be subject to U.S. federal income tax on any gain attributable to such sale unless such gain is effectively connected with its conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, is attributable to a permanent establishment or fixed base that such holder maintains in the United States). Gains that are effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that such holder maintains in the United States) generally will be subject to U.S. federal income tax at the same regular U.S. federal income tax rates applicable to a comparable U.S. Holder and, in the case of a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes, also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

Taxation of Redemption as a Distribution

If the redemption of a U.S. Holder’s public shares is treated as a distribution, as described above under “Tax Treatment of Redeeming Shareholders — U.S. Holders — Generally,” any portion of such distribution treated as a dividend paid to a Non-U.S. Holder in respect of our public shares generally will not be subject to U.S. federal income tax, unless the dividends are effectively connected with the Non-U.S. Holder’s conduct of a trade or business within the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that such holder maintains in the United States).

Dividends that are effectively connected with the Non-U.S. Holder’s conduct of a trade or business in the United States (and, if required by an applicable income tax treaty, are attributable to a permanent establishment or fixed base that such holder maintains in the United States) generally will be subject to U.S. federal income tax at the same regular U.S. federal income tax rates applicable to a comparable U.S. Holder and, in the case of a Non-U.S. Holder that is a corporation for U.S. federal income tax purposes, also may be subject to an additional branch profits tax at a 30% rate or a lower applicable tax treaty rate.

Information Reporting and Backup Withholding

Proceeds from the redemption of our public shares may be subject to information reporting to the IRS and possible United States backup withholding. Backup withholding will not apply, however, to a U.S. Holder who furnishes a correct taxpayer identification number and makes other required certifications, or who is otherwise exempt from backup withholding and establishes such exempt status. Information reporting and backup withholding generally will not apply to a Non-U.S. Holder who provides certification of its foreign status, under penalties of perjury, on a duly executed applicable IRS Form W-8 or by otherwise establishing an exemption.

Backup withholding is not an additional tax. Amounts withheld as backup withholding may be credited against a holder’s U.S. federal income tax liability, and a holder generally may obtain a refund of any excess amounts withheld under the backup withholding rules by timely filing the appropriate claim for refund with the IRS and furnishing any required information.

SHAREHOLDER PROPOSALS

If the Articles Amendment Proposals are approved, we anticipate that we will hold another extraordinary general meeting before the Extended Date to consider and vote upon the Proposed Business Combination and related transactions. Accordingly, our next annual general meeting of shareholders would be held at a future date to be determined by the post-business combination company. We expect that the post-business combination company would notify shareholders of the deadline for submitting a proposal for inclusion in the proxy statement for its next annual general meeting following the completion of the initial business combination. For any proposal to be considered for inclusion in the proxy statement and form of proxy for submission to shareholders at the 2024 annual general meeting of shareholders, it must be submitted in writing and comply with the requirements of Rule 14a-8 of the Exchange Act and the Articles in place at such time. We anticipate that the 2024 annual general meeting of shareholders would be held no later than December 31, 2024.

Alternatively, if the Articles Amendment Proposals are not approved and we do not consummate an initial business combination by November 15, 2023, we will liquidate and dissolve, and there will be no annual general meeting of shareholders in 2024.

MEMORANDUM AND ARTICLES OF ASSOCIATION
OF
BLOCKCHAIN COINVESTORS ACQUISITION CORP. I
SEPTEMBER [ ], 2023

RESOLVED, as a special resolution, that:

(i) Article 51.7 of the Amended and Restated Articles of Association of BCSA be deleted in its entirety and replaced as follows:
