CARTESIAN GROWTH CORPORATION (AFTER ITS DOMESTICATION AS A CORPORATION INCORPORATED IN THE STATE OF DELAWARE AND RENAMING

AS ALVARIUM TIEDEMANN HOLDINGS, INC. IN CONNECTION WITH THE DOMESTICATION)

The board of directors (the “Board”) of Cartesian has unanimously approved (i) the Domestication of Cartesian as a Delaware corporation (the “Domestication”) and (ii) the Business Combination Agreement, dated as of September 19, 2021 (as the same has been or may be amended, modified, supplemented or waived from time to time, the “Business Combination Agreement”), by and among Cartesian, Rook MS LLC, a Delaware limited liability company (“Umbrella Merger Sub”), Tiedemann Wealth Management Holdings, LLC, a Delaware limited liability company (“TWMH”), TIG Trinity GP, LLC, a Delaware limited liability company (“TIG GP”), TIG Trinity Management, LLC, a Delaware limited liability company (“TIG MGMT” and, together with TIG GP, the “TIG Entities”), Alvarium Investments Limited, an English private limited company (“Alvarium” and, together with TWMH and the TIG Entities, the “Target Companies” and each a “Target Company”), and Alvarium Tiedemann Capital LLC, a Delaware limited liability company (“Umbrella”), a copy of which is attached to the accompanying proxy statement/prospectus as Annex A-1. In connection with the transactions contemplated by the Business Combination Agreement (the “Business Combination”), the Company will be renamed “Alvarium Tiedemann Holdings, Inc.” and is referred to herein as “Alvarium Tiedemann”.

Upon consummation of the Business Combination, the combined company will be organized in an “Up-C” structure. Alvarium Tiedemann will hold Class A Common Units representing 63% and 50% of the total Common Units of Umbrella under the No Redemptions and Maximum Redemptions scenarios (each as defined below), respectively. Umbrella, in turn, will hold a newly formed entity that will ultimately be named “Alvarium Tiedemann Holdings, LLC.”

As described in this proxy statement/prospectus, Cartesian’s shareholders are being asked to consider and vote upon (among other things) the Business Combination, the Domestication and the other proposals set forth herein.

The accompanying prospectus covers 142,662,728 shares of Class A Common Stock, 20,400,000 shares of Class A Common Stock issuable upon exercise of warrants and 20,400,000 warrants to acquire shares of Class A Common Stock.

Cartesian intends to apply for listing, to be effective at the time of the Business Combination, of Alvarium Tiedemann’s Class A Common Stock and warrants to purchase Class A Common Stock on Nasdaq under the symbols “GLBL” and “GLBLW” respectively.

This proxy statement/prospectus provides you with detailed information about the Business Combination and other matters to be considered at the Special Meeting. We urge you to carefully read this

entire document and the documents incorporated herein by reference. You should also carefully consider the risk factors described in “Risk  Factors” beginning on page 72 of this proxy statement/prospectus.

After careful consideration, the Board has unanimously approved the Business Combination Agreement and the Business Combination and determined that each of the proposals to be presented at the Special Meeting is in the best interests of the Company and its shareholders, and unanimously recommends that you vote or give instruction to vote “FOR” each of those proposals.

The existence of financial and personal interests of our directors and officers may result in conflicts of interest, including a conflict between what may be in the best interests of Cartesian and its shareholders and what may be best for a director’s personal interests when determining to recommend that shareholders vote for the proposals. See the sections entitled “Summary of the Proxy Statement/Prospectus —Interests of Certain Persons in the Business Combination” and “Beneficial Ownership of Securities” in the accompanying proxy statement/prospectus for a further discussion.

Your vote is very important.

Please submit your proxy promptly whether or not you expect to participate in the meeting. Submitting a proxy now will NOT prevent you from being able to vote during the Special Meeting. If you hold your shares in “street name”, you should instruct your broker, bank or other nominee how to vote in accordance with the voting instruction form you receive from your broker, bank or other nominee.

On behalf of our Board, I would like to thank you for your support of Cartesian and look forward to a successful completion of the Business Combination.

Very truly yours,

The above matters are more fully described in the accompanying proxy statement/prospectus, which also includes, as Annex A-1, a copy of the Business Combination Agreement. We urge you to carefully read the accompanying proxy statement/prospectus in its entirety, including the Annexes and accompanying financial statements.

After careful consideration, the Board has determined that each of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Advisory Charter Proposals, the Stock Issuance Proposal, the Equity Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal, the Election of Directors Proposal and the Adjournment Proposal are in the best interests of Cartesian and its shareholders and unanimously recommends that you vote or give instruction to vote “FOR” each of those proposals.

The existence of financial and personal interests of Cartesian’s directors may result in a conflict of interest on the part of one or more of the directors between what she, he or they may believe is in the best interests of Cartesian and its shareholders and what she, he or they may believe is best for herself, himself or themselves in determining to recommend that shareholders vote for the proposals. See the sections entitled “Summary of the Proxy Statement/Prospectus —Interests of Certain Persons in the Business Combination” and “Beneficial Ownership of Securities” in the accompanying proxy statement/prospectus for a further discussion.

The Record Date for the Special Meeting is                 , 2022. Only holders of record of Class A ordinary shares and Class B ordinary shares at the close of business on the Record Date are entitled to notice of and to vote and have their votes counted at the Special Meeting and any adjournments or postponements of the Special Meeting. A complete list of Cartesian’s shareholders of record entitled to vote at the Special Meeting will be available for ten days before the Special Meeting at Cartesian’s principal executive offices for inspection by shareholders during ordinary business hours for any purpose germane to the Special Meeting and electronically during the Special Meeting at                .

Our Class A ordinary shares and warrants are currently listed on Nasdaq under the symbols “GLBL” and “GLBLW,” respectively. Certain of our Class A ordinary shares and warrants currently trade as units consisting of one Class A ordinary share and one-third of one redeemable warrant, and are listed on Nasdaq under the symbol “GLBLU.” The units will automatically separate into their component securities upon consummation of the Business Combination and, as a result, will no longer trade as an independent security. Upon the consummation of the Domestication, we intend to change our name from “Cartesian Growth Corporation” to “Alvarium Tiedemann Holdings, Inc.”

Pursuant to Cartesian’s amended and restated memorandum and articles of association (the “Existing Articles”), a holder of Public Shares (a “Public Shareholder”) may request that Cartesian redeem all or a portion of its Public Shares for cash if the Business Combination is consummated. You will be entitled to receive cash for any Public Shares to be redeemed only if you:

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 even if they vote for the Business Combination Proposal. If the Business Combination is not consummated, the Public Shares will not be redeemed for cash. If a Public Shareholder properly exercises its right to redeem its Public Shares and timely delivers its shares to the Transfer Agent, 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 (the “Trust Account”) established in connection with the Company’s initial public offering of its units, each consisting of one Class A ordinary share and one-third of one redeemable warrant, pursuant to its registration statements on Form S-1 declared effective by the SEC on February 23, 2021 (SEC File Nos. 333-252784 and 333-253428) (the “IPO”), calculated as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account (net of taxes payable), divided by the number of then-outstanding Public Shares. As of                 , 2022, this would have amounted to approximately $                per Public Share. If a Public Shareholder exercises its Redemption Rights, then it will be exchanging its redeemed Public Shares for cash and will no longer own such shares. Any request to redeem Public Shares, once made, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with our consent, until the Closing. Furthermore, if a holder of a Public Share delivers its certificate in connection with an election of its redemption and subsequently decides prior to the applicable date not to elect to exercise such rights, it may simply request that we instruct our Transfer Agent to return the certificate (physically or electronically). The holder can make such request by contacting the Transfer Agent, at the address or email address listed in this proxy statement/prospectus. We will be required to honor such request only if made prior to the deadline for exercising redemption requests. See “Special Meeting of the Shareholders” in the accompanying proxy statement/prospectus for a detailed description of the procedures to be followed if you wish to redeem your Public Shares for cash.

Notwithstanding the foregoing, a holder of Public Shares, together with any affiliate of such Public Shareholder or any other person with whom such Public Shareholder is acting in concert or as a “group” (as defined in Section 13 of the Exchange Act), will be restricted from redeeming its Public Shares with respect to more than an aggregate of 15% of the Public Shares, without our prior consent. Accordingly, if a Public Shareholder, alone or acting in concert as a group, seeks to redeem more than 15% of the Public Shares, then any such shares in excess of that 15% limitation would not be redeemed for cash, without our prior consent.

The approval of each of the Conditions Precedent Proposals (i.e., the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Equity Incentive Plan Proposal, and the Employee Stock Purchase Plan Proposal) is a condition to the consummation of the Business Combination. The adoption of each Condition Precedent Proposal is conditioned on the approval of all of the Condition Precedent Proposals. The Advisory Charter Proposals and the Adjournment Proposal are not conditioned on the approval of any other proposal. If our shareholders do not approve each of the Condition Precedent Proposals, the Business Combination may not be consummated.

Your attention is directed to the proxy statement/prospectus accompanying this notice (including the annexes thereto) for a more complete description of the proposed Business Combination and related transactions and each of the proposals. We urge you to read the accompanying proxy statement/prospectus carefully. If you have any questions or need assistance voting your Cartesian ordinary shares, please contact Morrow Sodali LLC,

our proxy solicitor, by calling (800) 662-5200, or banks and brokers can call collect at (203) 658-9400 or by emailing GLBL.info@investor.morrowsodali.com. This notice of Special Meeting and the proxy statement are available at                .

PRESENTATION OF CERTAIN FINANCIAL INFORMATION

For financial presentation purposes, total assets under management and assets under advisement (“AUM / AUA”) of the Company consists of: (i) assets under management (“AUM”) and assets under advisement (“AUA”) of TWMH; (ii) AUM of TIG; and (iii) AUM and AUA of Alvarium.

AUM / AUA of TWMH includes billable and non-billable assets. Billable assets represent the portion of assets on which TWMH charges fees. Non-billable assets are exempt of fees. They consist of assets such as cash and cash equivalents, real estate, investment consulting assets and other designated assets.

AUA of Alvarium includes billable and non-billable assets. Billable assets represent the portion of assets on which Alvarium charges fees; these are assets in which Alvarium is acting in a fiduciary capacity as well as co-investment assets. For the purpose of calculating co-investment assets, Alvarium includes the gross asset

11

value of all assets managed or supervised by operating partner subsidiaries, affiliates and joint ventures in which Alvarium holds either a majority or minority stake. Non-billable assets are exempt of fees.

AUM of TIG includes the assets under management of the TIG Entities and their subsidiaries, and each of the External Strategic Managers in which the TIG Entities have made strategic investments. External Strategic Managers are those managers in which the TIG Entities have made an external investment, and the strategies of these managers include Real Estate Bridge Lending, European Long/Short Equity and Asian Credit. AUM of TIG as of, and for the fiscal year ended, December 31, 2019, include the TIG Entities’ minority interests in its European Long / Short Equity and Asian Credit External Strategic Managers. The acquisition of these investments closed on March 10, 2020, and December 31, 2020, respectively. Such amounts are included as we believe it provides a more accurate representation of the growth of the underlying business of TIG.

Unless otherwise defined, AUM refers to assets on which a business provides continuous and regular billable supervisory or management services. As noted, the AUM of TIG and the Company includes the AUM of TIG’s External Strategic Managers as we believe including such AUM presents a more accurate depiction of the respective businesses. However, the AUM of the External Strategic Managers should not be viewed as part of the AUM of TIG or of Alvarium Tiedemann for regulatory and/or statutory purposes under the U.S. Investment Advisers Act of 1940, as amended.

EBITDA, Adjusted EBITDA, Economic EBITDA and Economic Revenue as presented in this proxy statement/prospectus are supplemental measures of our performance that are not required by, or presented in accordance with, US GAAP or UK GAAP. None of EBITDA, Adjusted EBITDA, Economic EBITDA, Economic Revenue or any figure derived therefrom is a measurement of Cartesian’s or any of the Target Company’s financial performance under US GAAP or UK GAAP and should not be considered as an alternative to net income or any other performance measure presented in accordance with US GAAP or UK GAAP or as an alternative to cash flows from operating activities as a measure of liquidity. Because EBITDA, Adjusted EBITDA, Economic EBITDA and Economic Revenue are not measures determined in accordance with US GAAP or UK GAAP and are thus susceptible to varying calculations, EBITDA, Adjusted EBITDA, Economic EBITDA and Economic Revenue and any figure derived therefrom, as presented, may not be comparable to other similarly titled measures of other corporations.

QUESTIONS AND ANSWERS ABOUT THE PROPOSALS

The following questions and answers briefly address some commonly asked questions about the proposals to be presented at the Special Meeting, including the Business Combination. The following questions and answers do not include all the information that is important to our shareholders. We urge our shareholders to carefully read this entire proxy statement/prospectus, including the annexes and other documents referred to herein.

15

Cartesian will hold the Special Meeting to, among other things, obtain the approvals required for the Business Combination and the other transactions contemplated by the Business Combination Agreement and you are receiving this proxy statement/prospectus in connection with such meeting. See “Proposal No. 1.–The Business Combination Proposal —The Business Combination Agreement” beginning on page 135. In addition, a copy of the Business Combination Agreement is attached to this proxy statement/prospectus as Annex A-1.

The Business Combination cannot be completed unless Cartesian’s shareholders approve the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Equity Incentive Plan Proposal and the Employee Stock Purchase Plan Proposal set forth in this proxy statement/prospectus for their approval. Information about the Special Meeting, the Business Combination and the other business to be considered by shareholders at the Special Meeting is contained in this proxy statement/prospectus.

This document constitutes a proxy statement of Cartesian and a prospectus of Cartesian. It is a proxy statement because Cartesian’s Board is soliciting proxies using this proxy statement/prospectus from its shareholders. It is a prospectus because Cartesian, in connection with the Business Combination, is offering shares of Class A Common Stock in exchange for its outstanding Class A ordinary shares. See “Proposal No. 1.–The Business Combination Proposal—The Business Combination Agreement—Consideration to be Received in the Business Combination”.

YOUR VOTE IS IMPORTANT. SHAREHOLDERS ARE URGED TO SUBMIT THEIR PROXIES AS SOON AS POSSIBLE AFTER CAREFULLY REVIEWING THIS PROXY STATEMENT/PROSPECTUS.

19

Following the Closing, in addition to the consideration to be received in connection with the Umbrella Merger, if, at any time during the Earn-Out Period, (i) the First Level Earn-Out Target is achieved, then within ten Business Days following the achievement of the First Level Earn-Out Target, the Company will issue, and will cause Umbrella to issue, 50% of the TWMH Members Earn-Out Consideration to the TWMH Members in accordance with, and pursuant to, the TWMH Payment Spreadsheet and (ii) the Second Level Earn-Out Target is achieved, then within ten Business Days following the achievement of the Second Level Earn-Out Target, Cartesian will issue, and will cause Umbrella to issue, 50% of the TWMH Members Earn-Out Consideration to the TWMH Members in accordance with, and pursuant to, the TWMH Payment Spreadsheet.

For more information on the consideration the shareholders of Alvarium and the members of TWMH and the TIG Entities will receive in connection with the Business Combination, see “Proposal No. 1.–The Business Combination Proposal – The Business Combination Agreement – Consideration to be Received in the Business Combination.”

The integration of the Target Companies may present material challenges, including, without limitation:

20

Some of those factors are outside of our control, and any one of them could result in delays, increased costs, decreases in the amount of potential revenues or synergies, potential cost savings, and diversion of management’s time and energy, which could materially affect our financial position, results of operations, and cash flows.

21

22

Please also see the sections “Certain Relationships and Related Person Transactions,” “Executive Compensation” and “Beneficial Ownership of Securities” for more information on the interests and relationships of our Sponsor, current officers and directors, and the Target Companies’ current owners.

The following table shows the Public Shareholders’ and our initial shareholders’ (including the Sponsor’s) investment per share and how these compare to the implied value of one share of common stock upon the completion of the Business Combination. The following table assumes that (i) our valuation is $345,171,114 (which is the amount we held in our trust account as of March 31, 2022), (ii) no additional interest is earned on the funds held in the trust account, (iii) no Public Shares are redeemed in connection with the Business Combination and (iv) all Founder Shares are held by the Sponsor and independent directors upon completion of the Business Combination, and does not take into account other potential impacts on our valuation at the time of the Business Combination such as (a) the trading price of our common stock, (b) the transaction costs incurred in connection with the Business Combination (including payment of $12,075,000 of deferred underwriting commissions), (c) any equity issued or cash paid to the equityholders of the Target Companies, (d) any equity issued to other third party investors, (e) the transfer of any Private Placement Warrants from the Sponsor to the equityholders of the Target Companies, (f) the exercise of any options under the Option Agreements, (g) the issuance of any portion of the Aggregate Earn-Out Consideration, (h) the forfeiture by the Sponsor of 2,850,000 Founder Shares pursuant to the Sponsor Support Agreement, or (i) the Target Companies’ businesses themselves.

Based on these assumptions, each share of common stock would have an implied value of $8.00 per share upon completion of the Business Combination, representing a 20% decrease from the initial implied value of $10.00 per Public Share. While the implied value of $8.00 per share upon completion of the Business Combination would represent a dilution to our Public Shareholders, this would represent a significant increase in value for the Sponsor relative to the price it paid for each Founder Share. At $8.00 per share, the 8,625,000 shares of common stock that the Sponsor and our independent directors holding Founder Shares would own upon

23

completion of the Business Combination would have an aggregate implied value of $69,000,000. As a result, even if the trading price of the common stock significantly declines following the consummation of the Business Combination, the value of the Founder Shares held by the Sponsor and independent directors will be significantly greater than the amount the Sponsor paid to purchase such shares. In addition, the Sponsor could potentially recoup its entire investment, inclusive of its investment in the Private Placement Warrants, even if the trading price of the common stock after the initial business combination is as low as $1.03 per share. As a result, the Sponsor and independent directors holding Founder Shares are likely to earn a substantial profit on their investment in us upon disposition of shares of common stock even if the trading price of common stock declines after we complete the Business Combination. The Sponsor and independent directors holding Founder Shares may therefore be economically incentivized to complete on the Business Combination, even if its terms are not in the best interests of the Public Shareholders, rather than liquidating Cartesian. This dilution would increase to the extent that Public Shareholders seek redemptions from the trust account for their Public Shares. See “Risk Factors — Risks Related to the Business Combination — The nominal purchase price paid by the Sponsor for the Founder Shares may significantly dilute the implied value of the Public Shares upon completion of the Business Combination. In addition, upon completion of the Business Combination, the value of the Sponsor’s Founder Shares will be significantly greater than the amount the Sponsor paid to purchase such shares, even if the Business Combination causes the trading price of the Company’s common stock to materially decline.”

24

The Business Combination is conditioned upon the approval of the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Stock Issuance Proposal, the Equity Incentive Plan Proposal and the Employee Stock Purchase Plan Proposal, subject to the terms of the Business Combination Agreement. The Business Combination is not conditioned on the Advisory Charter Proposals or the Adjournment Proposal. If the Business Combination Proposal is not approved, the other proposals (except the Adjournment Proposal) will not be presented to the shareholders for a vote.

Cartesian will hold the Special Meeting of our shareholders to consider and vote upon these proposals. This proxy statement/prospectus contains important information about the Business Combination and the other matters to be acted upon at the Special Meeting. Shareholders should read it carefully.

After careful consideration, the Board has unanimously approved the Business Combination Agreement and the transactions contemplated thereby and determined that each of the Business Combination Proposal, the Domestication Proposal, Organizational Documents Proposal, the Advisory Charter Proposals, the Stock Issuance Proposal, the Equity Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal, the Election of Directors Proposal and the Adjournment Proposal is in the best interests of Cartesian and its shareholders and unanimously recommends that you vote “FOR” or give instruction to vote “FOR” each of these proposals.

The existence of financial and personal interests of our directors and officers may result in conflicts of interest, including a conflict between what may be in the best interests of the Company and its shareholders and what may be best for a director’s personal interests when determining to recommend that shareholders vote for the proposals. See the sections entitled “Summary of the Proxy Statement/Prospectus —Interests of Certain Persons in the Business Combination,” “Executive Compensation” and “Beneficial Ownership of Securities” in the accompanying proxy statement for a further discussion.

THE VOTE OF SHAREHOLDERS IS IMPORTANT. SHAREHOLDERS ARE URGED TO SUBMIT THEIR PROXIES AS SOON AS POSSIBLE AFTER CAREFULLY REVIEWING THIS PROXY STATEMENT/PROSPECTUS.

25

Notwithstanding the foregoing, a holder of Public Shares, together with any affiliate of such Public Shareholder or any other person with whom such Public Shareholder is acting in concert or as a “group” (as defined in Section 13 of the Exchange Act), will be restricted from redeeming its Public Shares with respect to more than an aggregate of 15% of the Public Shares, without our prior consent. Accordingly, if a Public Shareholder, alone or acting in concert or as a group, seeks to redeem more than 15% of the Public Shares, then any such shares in excess of that 15% limit would not be redeemed for cash, without our prior consent.

Our initial shareholders entered into a letter agreement pursuant to which they have agreed to waive, for no additional consideration, their Redemption Rights with respect to their Founder Shares and Public Shares in connection with the completion of a business combination.

The consummation of the Business Combination is conditioned upon, among other things, approval by Cartesian’s shareholders of the Business Combination Agreement and the Business Combination. Unless waived, if any of these conditions are not satisfied, the Business Combination may not be consummated. Furthermore, in no event will we redeem our Public Shares in an amount that would cause our net tangible assets to be less than $5,000,001. See “Proposal No. 1.–The Business Combination Proposal — The Business Combination Agreement.”

The address of the Transfer Agent is listed under the question “Who can help answer my questions?” below.

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.

Any holder of Public Shares will be entitled to request that their Public Shares be redeemed for a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account (net of taxes payable), divided by the number of then-outstanding Public Shares. As of March 31, 2022, this would have amounted to approximately $10.00 per Public Share. However, the proceeds deposited in the Trust Account could become subject to the claims of our creditors, if any, which could have priority over the claims of our Public Shareholders, regardless of whether such Public Shareholders vote for or against the Business Combination Proposal. Therefore, the per share distribution from the Trust Account in such a situation may be less than originally anticipated due to such claims. Your vote on any proposal other than the Business Combination Proposal will have no impact on the amount you will receive upon exercise of your Redemption Rights. We anticipate that the funds to be distributed to Public Shareholders electing to redeem their Public Shares will be distributed promptly after the consummation of the Business Combination.

26

If you are a holder of Public Shares, you may exercise your Redemption Rights by submitting your request in writing to the Transfer Agent at the address listed at the end of this section.

Any request for redemption, once made by a holder of Public Shares, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with our consent, until the Closing. If you deliver your shares for redemption to the Transfer Agent and later decide prior to Closing not to elect redemption, you may request that Cartesian instruct our Transfer Agent to return the shares (physically or electronically). You may make such request by contacting the Transfer Agent at the phone number or address listed at the end of this section. We will be required to honor such request only if made prior to the deadline for exercising redemption requests.

Any corrected or changed written exercise of Redemption Rights must be received by the Transfer Agent prior to the deadline for exercising redemption requests and, thereafter, with our consent, prior to Closing. No request for redemption will be honored unless the holder’s stock has been delivered (either physically or electronically) to the Transfer Agent by 5:00 p.m., Eastern Time, on                 , 2022.

If a holder of Public Shares properly makes a request for redemption and the Public Shares are delivered as described above, then, if the Business Combination is consummated, the Company will redeem Public Shares for a pro rata portion of funds deposited in the Trust Account, calculated as of two business days prior to the consummation of the Business Combination. If you are a holder of Public Shares and you exercise your Redemption Rights, it will not result in the loss of any Cartesian warrants that you may hold.

27

Additionally, because the Domestication will occur immediately prior to the redemption of U.S. holders that exercise Redemption Rights, U.S. holders exercising Redemption Rights will be subject to the potential tax consequences of Section 367 of the Code and the potential tax consequences of the rules applicable to a company treated as a “passive foreign investment company” (“PFIC”), as a result of the Domestication. The tax consequences of exercising Redemption Rights are discussed more fully below under “Material U.S. Federal Income Tax Considerations — U.S. Holders — Effect to U.S. Holders of Company Common Stock Exercising Redemption Rights.”

To effect the Domestication, Cartesian will file a notice of deregistration with the Cayman Islands Registrar of Companies, together with the necessary accompanying documents, and file a certificate of incorporation and a certificate of corporate domestication with the Secretary of State of the State of Delaware, under which Cartesian will be domesticated and continue as a Delaware corporation, at which time Cartesian will change its name to “Alvarium Tiedemann Holdings, Inc.”

The approval of the Domestication Proposal is a condition to the closing of the transactions contemplated by the Business Combination Agreement. The approval of the Domestication Proposal requires a special resolution under Cayman Islands law, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Abstentions and broker non-votes, while considered present for the purposes of establishing a quorum, will not count as a vote cast at the Special Meeting.

28

As discussed further under “Material U.S. Federal Income Tax Considerations” below, Cartesian believes that it is likely classified as a PFIC for U.S. federal income tax purposes. In the event that Cartesian is considered a PFIC then, notwithstanding the foregoing U.S. federal income tax consequences of the Domestication, proposed Treasury Regulations under Section 1291(f) of the Code (which have a retroactive effective date), if finalized in their current form, generally would require a U.S. holder to recognize gain as a

29

result of the Domestication. Any such gain would be taxed as ordinary income and an interest charge would apply based on a complex set of rules. However, it is difficult to predict whether, in what form, and with what effective date, final Treasury Regulations under Section 1291(f) of the Code will be adopted. Importantly, however, U.S. holders that make or have made certain elections discussed further under “Material U.S. Federal Income Tax Considerations — U.S. Holders — PFIC Considerations” with respect to their Cartesian ordinary shares are generally not subject to the same gain recognition rules under the currently proposed Treasury Regulations under Section 1291(f) of the Code. For a more complete discussion of the potential application of the PFIC rules to U.S. holders as a result of the Domestication, see “Material U.S. Federal Income Tax Considerations — U.S. Holders — PFIC Considerations.”

Additionally, the Domestication may cause non-U.S. holders (as defined in “Material U.S. Federal Income Tax Considerations — Non-U.S. Holders” below) to become subject to U.S. federal income withholding taxes on any dividends in respect of such non-U.S. holder’s Company common stock (or warrants) subsequent to the Domestication.

The tax consequences of the Domestication are complex and will depend on a holder’s particular circumstances. All holders are strongly urged to consult their tax advisor for a full description and understanding of the tax consequences of the Domestication, including the applicability and effect of U.S. federal, state, local and foreign income and other tax laws. For a more complete discussion of the U.S. federal income tax considerations of the Domestication, see “Material U.S. Federal Income Tax Considerations.”

If you are a holder of record of Cartesian ordinary shares on the Record Date, you may vote at the Special Meeting or by submitting a proxy for the Special Meeting. You may submit your proxy by completing, signing, dating and returning the enclosed proxy card in the accompanying pre-addressed postage paid envelope. If you hold your shares in “street name,” which means your shares are held of record by a broker, bank or nominee, you should contact your broker to ensure that votes related to the shares you beneficially own are properly counted. In this regard, you must provide the broker, bank or nominee with instructions on how to vote your shares or, if you wish to attend the Special Meeting and vote, obtain a proxy from your broker, bank or nominee.

30

As the beneficial holder, you have the right to direct your broker, bank or other nominee as to how to vote your shares. If you do not provide voting instructions to your broker on a particular proposal on which your broker does not have discretionary authority to vote, your shares will not be voted on that proposal. This is called a “broker non-vote.” Broker non-votes will not be counted for the purposes of determining the existence of a quorum. Moreover, broker non-votes will have no effect on any of the proposals in this proxy statement, except that broker non-votes will have the same effect as a vote “AGAINST” the Organizational Documents Proposal.

For the proposals in this proxy statement/prospectus, your broker will not have the discretionary authority to vote your shares. Accordingly, your bank, broker, or other nominee can vote your shares at the Special Meeting only if you provide instructions on how to vote. You should instruct your broker to vote your shares as soon as possible in accordance with directions you provide.

The existence of financial and personal interests of Cartesian’s directors and officers may result in conflicts of interest, including a conflict between what may be in the best interests of the Company and its shareholders and what may be best for a director’s personal interests when determining to recommend that shareholders vote for the proposals. These conflicts of interest include, among other things, that if we do not consummate an initial business combination by February 26, 2023, we may be forced to liquidate, and the 8,550,000 Founder Shares and 8,900,000 Private Placement Warrants owned by our Sponsor, and 75,000 Founder Shares owned by our director nominees, would be worthless. See the sections entitled “Summary of the Proxy Statement/Prospectus —Interests of Certain Persons in the Business Combination” and “Beneficial Ownership of Securities” for more information.

Entering into any such incentive arrangements may have a depressive effect on ordinary shares. For example, as a result of these arrangements, an investor or holder may have the ability to effectively purchase shares at a price lower than market and may therefore be more likely to sell the shares he owns, either prior to or immediately after the Special Meeting.

If such transactions are effected, the consequence could be to cause the Business Combination to be approved in circumstances where such approval could not otherwise be obtained. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the proposals to be presented at the Special Meeting and would likely increase the chances that such proposals would be approved. As of the date of this proxy statement/prospectus, there have been no such discussions and no agreements to such effect have been entered into with any such investor or holder. Cartesian will file a Current Report on Form 8-K to disclose any arrangements entered into or significant purchases made by any

35

of the aforementioned persons that would affect the vote on the proposals to be voted on at the Special Meeting. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

Cartesian warrant holders should not submit the certificates relating to their warrants. Public Shareholders who do not elect to have their Public Shares redeemed for the pro rata share of the Trust Account should not submit the certificates relating to their Public Shares.

Following the Domestication and the effectiveness of the Business Combination, holders of Cartesian’s ordinary shares and warrants will receive shares of Class A Common Stock and warrants of the Company

36

without needing to take any action and accordingly such holders should not submit the certificates relating to their ordinary shares and warrants. In addition, before the Closing, each outstanding unit of Cartesian (each of which consists of one Class A ordinary shares and one-third of one warrant to purchase one Class A ordinary share) will be separated into its component Class A ordinary share and warrant.

Proposals to be Submitted at the Special Meeting

The Business Combination Proposal

The approval of the Business Combination Proposal requires an ordinary resolution under the Existing Articles, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. Cartesian shareholders must approve the Business Combination Proposal in order for the Business Combination to occur. If Cartesian shareholders fail to approve the Business Combination Proposal, the Business Combination will not occur. For additional information, see “Proposal No. 1 – The Business Combination Proposal” section of this proxy statement/prospectus.

The Domestication Proposal

The approval of the Domestication Proposal requires a special resolution under the Existing Articles, being the affirmative vote of at least two-thirds of the votes cast by holders of ordinary shares who, being present in person or represented by proxy and entitled to vote at the Special Meeting, vote at the Special Meeting. The Domestication Proposal is conditioned on the approval of the Business Combination Proposal. Therefore, if the Business Combination Proposal is not approved, the Domestication Proposal will have no effect, even if approved by Cartesian’s Public Shareholders. For additional information, see “Proposal No. 2 – The Domestication Proposal” section of this proxy statement/prospectus.

The Organizational Documents Proposal

The approval of the Organizational Documents Proposal requires a special resolution under the Existing Articles, being the affirmative vote of the holders of at least two-thirds of the ordinary shares who, being present in person or represented by proxy and entitled to vote at the Special Meeting, vote at the Special Meeting. The Organizational Documents Proposal is conditioned on the approval of the Domestication Proposal, and, therefore, also conditioned on approval of the Business Combination Proposal. Therefore, if the Business Combination Proposal or the Domestication Proposal is not approved, the Organizational Documents Proposal will have no effect, even if approved by Cartesian’s Public Shareholders. For additional information, see “Proposal No. 3 – The Organizational Documents Proposal” section of this proxy statement/prospectus.

The Advisory Charter Proposals

The approval of the Advisory Charter Proposals requires an ordinary resolution, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting,

39

vote at the Special Meeting. The approval of any of the Advisory Charter Proposals is not otherwise required by the Existing Articles or Delaware law separate and apart from the Organizational Documents Proposal, but pursuant to SEC guidance, Cartesian is required to submit these provisions to its shareholders separately for approval. However, the shareholder votes regarding these proposals are advisory votes, and are not binding on Cartesian or the Board (separate and apart from the approval of the Organizational Documents Proposal). Furthermore, the Business Combination is not conditioned on the separate approval of the Advisory Charter Proposals (separate and apart from approval of the Organizational Documents Proposal). For additional information, see “Proposal No. 4 – The Advisory Charter Proposals” section of this proxy statement/prospectus.

The Stock Issuance Proposal

The approval of the Stock Issuance Proposal requires an ordinary resolution, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Stock Issuance Proposal is conditioned on the approval of the Organizational Documents Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal and the Domestication Proposal. Therefore, if any of those proposals is not approved, the Stock Issuance Proposal will have no effect, even if approved by Cartesian’s Public Shareholders. For additional information, see “Proposal No. 5 – The Stock Issuance Proposal” section of this proxy statement/prospectus.

The Equity Incentive Plan Proposal

The approval of the Equity Incentive Plan Proposal requires an ordinary resolution, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Equity Incentive Plan Proposal is conditioned on the approval of the Stock Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal and the Organizational Documents Proposal. Therefore, if any of those proposals is not approved, the Equity Incentive Plan Proposal will have no effect, even if approved by Cartesian’s Public Shareholders. For additional information, see “Proposal No. 6 – The Equity Incentive Plan Proposal” section of this proxy statement/prospectus.

The Employee Stock Purchase Plan Proposal

The approval of the Employee Stock Purchase Plan Proposal requires an ordinary resolution, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Employee Stock Purchase Plan Proposal is conditioned on the approval of the Stock Issuance Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal, the Domestication Proposal and the Organizational Documents Proposal. Therefore, if any of those proposals is not approved, the Employee Stock Purchase Plan Proposal will have no effect, even if approved by Cartesian’s Public Shareholders. Pursuant to the IPO Letter Agreements, the Sponsor and Cartesian’s officers and directors have agreed to vote shares representing approximately 20% of the aggregate voting power of the ordinary shares in favor of the Employee Stock Purchase Plan Proposal. For additional information, see “Proposal No. 7 – The Employee Stock Purchase Plan Proposal” section of this proxy statement/prospectus.

Election of Directors Proposal

The approval of the election of each director nominee pursuant to the Election of Directors Proposal requires an ordinary resolution under the Existing Articles, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Election of Directors Proposal is conditioned on the approval of the Organizational Documents Proposal and, therefore, also conditioned on the approval of the Business Combination Proposal and the Domestication Proposal. Therefore, if any of those proposals is not approved, the Election of Directors Proposal will have no

40

effect, even if approved by Cartesian’s Public Shareholders. For additional information, see “Proposal No. 8 – The Election of Directors Proposal” section of this proxy statement/prospectus.

The Adjournment Proposal

The approval of the Adjournment Proposal requires an ordinary resolution under the Existing Articles, being the affirmative vote of the holders of a majority of the ordinary shares who, being present and entitled to vote at the Special Meeting, vote at the Special Meeting. The Adjournment Proposal is not conditioned upon any other Shareholder Proposal. For additional information, see “Proposal No. 9 – The Adjournment Proposal” section of this proxy statement/prospectus.

Date, Time and Place of Special Meeting of Cartesian’s Shareholders

The Special Meeting will be held at 10:00 a.m., Eastern Time, on                     , 2022, at                , to consider and vote upon the proposals to be submitted to the Special Meeting, including if necessary, the adjournment proposal. For the purposes of Cartesian’s Existing Articles, the physical place of the meeting will be                . In light of the COVID-19 pandemic and to support the well-being of Cartesian’s shareholders, directors and officers, Cartesian encourages you to use remote methods of attending the Special Meeting or to attend via proxy. You may attend the Special Meeting and vote your shares electronically during the Special Meeting via live webcast by visiting https://www.cstproxy.com/cartesianspac/sm2022. You will need the meeting control number that is printed on your proxy card to enter the Special Meeting. You may also attend the meeting telephonically by dialing                .

Registering for the Special Meeting

Pre-registration at                 is recommended but is not required in order to attend.

Any shareholder wishing to attend the Special Meeting should register for the meeting by                 , 2022. To register for the Special Meeting, please follow these instructions as applicable to the nature of your ownership of our ordinary shares:

Voting Power; Record Date

Shareholders will be entitled to vote or direct votes to be cast at the Special Meeting if they owned ordinary shares at the close of business on                , 2022, which is the Record Date for the Special Meeting.

41

Shareholders will have one vote for each ordinary share owned at the close of business on the Record Date. 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. Our warrants do not have voting rights. On the Record Date, there were 43,125,000 ordinary shares outstanding, of which 34,500,000 were Public Shares, with the rest being held by our Sponsor and our independent directors.

Quorum and Vote of Shareholders

A quorum of our shareholders is necessary to hold a valid meeting. The presence, in person (which would include presence at the Special Meeting) or by proxy, of shareholders holding a majority of the issued and outstanding Cartesian ordinary shares entitled to vote at the Special Meeting constitutes a quorum at the Special Meeting. In the absence of a quorum, the Special Meeting shall be adjourned in accordance with the Existing Articles. As of the Record Date for the Special Meeting, 21,562,501 ordinary shares would be required to achieve a quorum.

Our Sponsor and our officers and directors at the time of the IPO entered into letter agreements to vote their Founder Shares as well as any Public Shares purchased during or after the IPO, in favor of the Business Combination Proposal. As of the date hereof, our Sponsor owns approximately 20% of our total outstanding ordinary shares.

The following votes are required for each proposal at the Special Meeting:

42

With respect to each proposal in this proxy statement/prospectus, you may vote “FOR,” “AGAINST” or “ABSTAIN.”

If a shareholder fails to return a proxy card or fails to instruct a broker or other nominee how to vote, and does not attend the Special Meeting in person, then the shareholder’s shares will not be counted for purposes of determining whether a quorum is present at the Special Meeting.

For the purposes of approval, an abstention will have no effect on the Business Combination Proposal, the Domestication Proposal, the Organizational Documents Proposal, the Advisory Charter Proposals, the Stock Issuance Proposal, the Equity Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal, the Election of Directors Proposal and the Adjournment Proposal.

Redemption Rights

Pursuant to the Existing Articles, a Public Shareholder may request that Cartesian redeem all or a portion of such Public Shareholder’s Public Shares for cash if the Business Combination is consummated. You will be entitled to receive cash for any Public Shares to be redeemed only if you:

As noted above, 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. Holders may instruct their broker to do so, 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 such Public Shareholder’s Public Shares even if they vote for the Business Combination Proposal. If the Business Combination is not consummated, the Public Shares will not be redeemed for cash. If a Public Shareholder properly exercises its right to redeem its Public Shares and timely delivers its Public Shares to the Transfer Agent, Cartesian will redeem each Class A ordinary share for a per share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the Business Combination, including interest earned on the funds held in the Trust Account (net of taxes payable), divided by the number of then-outstanding Public Shares. If a Public Shareholder exercises its Redemption Rights, then it will be exchanging its redeemed Public Shares for cash and will no longer own such shares. Any request to

43

redeem Public Shares, once made, may be withdrawn at any time until the deadline for exercising redemption requests and thereafter, with our consent, until the Closing. Furthermore, if a holder of a Public Shares delivers its certificate in connection with an election of its redemption and subsequently decides prior to the Closing not to elect to exercise such rights, it may simply request that Cartesian instruct our Transfer Agent to return the certificate (physically or electronically). The holder can make such request by contacting the Transfer Agent, at the address or email address listed in this proxy statement/prospectus. We will be required to honor such request only if made prior to the deadline for exercising redemption requests. See “Special Meeting of the Shareholders” for a detailed description of the procedures to be followed if you wish to redeem your Public Shares for cash.

Notwithstanding the foregoing, a holder of Public Shares, together with any affiliate of such Public Shareholder or any other person with whom such Public Shareholder is acting in concert or as a “group” (as defined in Section 13 of the Exchange Act), will be restricted from redeeming its Public Shares with respect to more than an aggregate of 15% of the Public Shares, without our prior consent. Accordingly, if a Public Shareholder, alone or acting in concert as a group, seeks to redeem more than 15% of the Public Shares, then any such shares in excess of that 15% limit would not be redeemed for cash, without our prior consent.

In order for Public Shareholders to exercise their Redemption Rights in respect of the Business Combination Proposal, Public Shareholders must properly exercise their right to redeem the Public Shares they hold no later than the close of the vote on the Business Combination Proposal and deliver their Public Shares (either physically or electronically) to the Transfer Agent prior to 5:00 p.m., Eastern Time, on                , 2022 (two business days prior to the vote at the Special Meeting). Immediately following the consummation of the Business Combination, the Company will satisfy the exercise of Redemption Rights by redeeming the Public Shares issued to the Public Shareholders that validly exercised their Redemption Rights.

Holders of our warrants will not have Redemption Rights with respect to the warrants.

Appraisal Rights

Neither our shareholders nor our warrant holders have appraisal rights in connection with the Business Combination or the Domestication under the Cayman Islands Companies Act or the DGCL.

Proxy Solicitation

Proxies may be solicited by mail, telephone or in person. Cartesian has engaged Morrow Sodali LLC to assist in the solicitation of proxies.

If a shareholder grants a proxy, it may still vote its shares in person (which would include presence at the Special Meeting) if it revokes its proxy before the Special Meeting. A shareholder also may change its vote by submitting a later-dated proxy as described in the section entitled “Special Meeting of the Shareholders — Revoking Your Proxy.”

Interests of Certain Persons in the Business Combination

In considering the recommendation of our Board to vote in favor of the Business Combination, shareholders should be aware that, aside from their interests as shareholders, our Sponsor and our directors, officers and advisors and the Target Companies’ current owners have interests in the Business Combination that are different from, or in addition to, those of our other shareholders generally. Our directors were aware of and considered these interests, among other matters, in evaluating the Business Combination, and in recommending to our shareholders that they approve the Business Combination. Shareholders should take these interests into account in deciding whether to approve the Business Combination. These interests include, among other things:

44

45

At any time prior to the Special Meeting, during a period when they are not then aware of any material non-public information regarding Cartesian or our securities, our initial shareholders, the Target Companies and/or their respective affiliates may purchase shares and/or warrants from investors, or they may enter into transactions with such investors and others to provide them with incentives to acquire Cartesian ordinary shares or vote their shares in favor of the Business Combination Proposal. The purpose of such share purchases and other transactions would be to increase the likelihood that the proposals presented to shareholders for approval at the Special Meeting are approved or to provide additional equity financing. Any such share purchases and other transactions may thereby increase the likelihood of obtaining shareholder approval of the Business Combination. This may result in the completion of the Business Combination that may not otherwise have been possible. While the exact nature of any such incentives has not been determined as of the date of this proxy statement/prospectus, they might include, without limitation, arrangements to protect such investors or holders against potential loss in value of their shares, including the granting of put options.

Entering into any such incentive arrangements may have a depressive effect on Cartesian ordinary shares. For example, as a result of these arrangements, an investor or holder may have the ability to effectively purchase shares at a price lower than market and may therefore be more likely to sell the shares he owns, either prior to or immediately after the Special Meeting.

If such transactions are effected, the consequence could be to cause the Business Combination to be approved in circumstances where such approval could not otherwise be obtained. Purchases of shares by the persons described above would allow them to exert more influence over the approval of the proposals to be presented at the Special Meeting and would likely increase the chances that such proposals would be approved. As of the date of this proxy statement/prospectus, there have been no such discussions and no agreements to such effect have been entered into with any such investor or holder. Cartesian will file a Current Report on Form 8-K to disclose any arrangements entered into or significant purchases made by any of the aforementioned persons that would affect the vote on the proposals to be voted on at the Special Meeting. Any such report will include descriptions of any arrangements entered into or significant purchases by any of the aforementioned persons.

The existence of financial and personal interests of our directors and officers may result in conflicts of interest, including a conflict between what may be in the best interests of the Company and its shareholders and what may be best for a director’s personal interests when determining to recommend that shareholders vote for the proposals. See the sections entitled “Risk Factors” and “Beneficial Ownership of Securities” for more information and other risks.

Satisfaction of 80% Test

It is a requirement under the Existing Articles that the business or assets acquired in its initial business combination have a fair market value equal to at least 80% of the assets held in the Trust Account (net of amounts previously disbursed to Cartesian’s management for taxes and excluding the amount of deferred underwriting discounts held in the Trust Account) at the time of the agreement to enter into such business combination. In addition, the rules of Nasdaq require that Cartesian’s initial business combination be with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in trust). As of September 19, 2021, the date of the execution of the

46

Business Combination Agreement, the balance of the Trust Account was approximately $333,000,000 (excluding the $12,075,000 deferred underwriting commissions and taxes payable on the income earned on the Trust Account) and 80% thereof represents approximately $266,000,000. In reaching its conclusion that the proposed Business Combination meets the 80% asset test, our Board used as a fair market value the enterprise value of approximately $1,079,900,000, which was implied based on the terms of the transactions agreed to by the parties in negotiating the Business Combination Agreement. The enterprise value consists of an implied equity value for TWMH (prior to the proposed Business Combination) of approximately $365,546,150, an implied equity value for the TIG Entities (prior to the proposed Business Combination) of approximately $380,232,790, and an implied equity value for Alvarium (prior to the proposed Business Combination) of approximately $334,121,060. In determining whether the enterprise value described above represents the fair market value of the Target Companies, the Board considered all of the factors described in the section of the proxy statement/prospectus entitled “Cartesian’s Board of Directors’ Reasons for Approval of the Business Combination” and the fact that the purchase price for these businesses was the result of an arm’s length negotiation. As a result, the Board concluded that the fair market value of the Company was significantly in excess of 80% of the assets held in the Trust Account (net of amounts previously disbursed to Cartesian’s management for taxes and excluding the amount of deferred underwriting discounts held in the Trust Account).

Certain United States Federal Income Tax Considerations

For a discussion summarizing the material United States federal income tax considerations of an exercise of Redemption Rights, please see “Material U.S. Federal Income Tax Considerations” below.”

Accounting Treatment of the Business Combination

The combined financial information presents the pro forma effects of the following transactions:

The Business Combination will be accounted for using the acquisition method with Alvarium Tiedemann as the accounting acquirer. Under the acquisition method of accounting, Alvarium Tiedemann’s assets and liabilities will be recorded at carrying value and the assets and liabilities associated with TWMH, the TIG Entities and Alvarium will be recorded at estimated fair value as of the acquisition date. The excess of the purchase price over the estimated fair values of the net assets acquired, if applicable, will be recognized as goodwill. For accounting purposes, the acquirer is the entity that has obtained control of another entity and, thus, consummated a business combination. The determination of whether control has been obtained begins with the evaluation of whether control should be evaluated based on the variable interest or voting interest model pursuant to ASC Topic 810, Consolidation (“ASC 810”). If the acquiree is a variable interest entity, the primary beneficiary would be the accounting acquirer. Umbrella, which will hold the assets and businesses of TWMH, the TIG Entities and Alvarium, meets the definition of a variable interest entity and Alvarium Tiedemann has been determined to be the primary beneficiary.

The Company has determined TWMH to be the predecessor entity to the Business Combination based on a number of considerations, including (i) TWMH former management making up the majority of the senior management team of Alvarium Tiedemann, (ii) Alvarium Tiedemann management’s evaluation of the business and its intention to market of TWMH as the primary business going forward, and (iii) TWMH’s leading indicators including it contributing the largest assets under advisement of the continuing operations of Alvarium Tiedemann. Therefore, operations presented prior to the Business Combination will be those of TWMH.

For a discussion summarizing the anticipated accounting treatment of the Business Combination, please see “Anticipated Accounting Treatment.”

52

Risk Factors

In evaluating the proposals to be presented at the Special Meeting, a shareholder should carefully read this proxy statement/prospectus and especially consider the factors discussed in the section entitled “Risk Factors.”

Sources of Industry and Market Data

Where information has been sourced from a third-party, the source of such information has been identified. Unless otherwise indicated, the information contained in this proxy statement/prospectus on the market environment, market developments, growth rates, market trends and competition in the markets in which Cartesian and the Target Companies operate is taken from publicly available sources, including third-party sources, or reflects Cartesian’s or the Target Companies’ estimates that are principally based on information from publicly available sources.

Recommendation of the Board

The Board believes that the Business Combination Proposal and the other proposals to be presented at the Special Meeting are in the best interest of Cartesian’s shareholders and unanimously recommends that our shareholders vote “FOR” the Business Combination Proposal, “FOR” the Domestication Proposal, “FOR” the Organizational Documents Proposal, “FOR” the Advisory Charter Proposals, “FOR” the Stock Issuance Proposal, “FOR” the Equity Incentive Plan Proposal, “FOR” the Employee Stock Purchase Plan Proposal, “FOR” each of the directors put forth in the Election of Directors Proposal, and “FOR” the Adjournment Proposal, if presented to the Special Meeting.

Selected Operating Metrics

We use EBITDA, Adjusted EBITDA and Economic EBITDA as non-US GAAP measures to track our performance and assess the TIG Entities’ ability to service their borrowings. We believe all three non-GAAP measures provide useful information to investors to help them evaluate our operating results by facilitating an enhanced understanding of our operating performance and enabling them to make more meaningful period to period comparisons. EBITDA, Adjusted EBITDA, and Economic EBITDA as presented in this proxy statement/ prospectus are supplemental measures of our performance that are not required by, or presented in accordance with, US GAAP. For more information, see “Presentation of Certain Financial Information.”
