Mobix Labs (MOBX) S-4/ARegistration of securities issued in business combination transactions (amended)

The aggregate transaction consideration to be paid at the Closing will be (i) an aggregate number of shares of Class A Common Stock or Class B Common Stock equal to $235 million, divided by $10.00, plus (ii) additional shares of Class A Common Stock that may be issued in exchange for equity securities issued by Mobix Labs in private placements for cash after March 26, 2023 to finance the ongoing business operations of Mobix Labs or to pay transaction expenses, which as of October 31, 2023 would be an additional 2,765,886 shares of Class A Common Stock. The estimated maximum number of such additional shares that may be issued is 3,000,000, and this estimate is provided solely for the purpose of registering a maximum amount of shares of Class A Common Stock under the registration statement on Form S-4 of which this proxy statement/prospectus forms a part in light of the fact that the Business Combination Agreement does not cap the number of such shares that may be issuable. The aggregate transaction consideration will be allocated among the holders of outstanding shares of common stock, preferred stock, options, RSUs, warrants and convertible instruments, including SAFEs and promissory notes of Mobix Labs immediately prior to the Closing (including in the form of Assumed Options or Assumed RSUs, as applicable) pro rata based on (a) the number of shares of Mobix Labs common stock that are either held by or issuable to a Mobix Labs equityholder pursuant to the terms of the preferred stock, options, RSUs, warrants or convertible instruments held by the Mobix Labs equityholders immediately prior to the Closing, and (b) the per share exchange ratio defined in the Business Combination Agreement. In addition to the consideration to be paid at the Closing, certain holders of outstanding shares of common stock, preferred stock and options (including both the in-the-money vested options and the Other Mobix Labs Options) of Mobix Labs (the “Earnout Recipients”) will be entitled to receive an additional aggregate 3.5 million shares of Class A Common Stock issuable as earnout shares (the “Earnout Shares”) based on the achievement of trading price targets following the Closing and subject to the terms provided in the Business Combination Agreement.

Based on the number of outstanding shares of Mobix Labs common stock, preferred stock, the number of shares of Mobix Labs common stock underlying the Mobix Labs in-the-money vested options and the warrants and the aggregate amount of Mobix Labs convertible instruments, including SAFEs and promissory notes, outstanding, in each case as of October 31, 2023, assuming no Chavant shareholders exercise redemption rights with respect to their Ordinary Shares in connection with the Transaction, the total numbers of shares of Class A Common Stock and Class B Common Stock expected to be issued in connection with the Closing are approximately 20,943,622 and 2,199,098, respectively. The holders of outstanding shares of common stock, preferred stock, in-the-money vested options, warrants and convertible instruments of Mobix Labs immediately prior to the Closing are expected to hold in the aggregate approximately 78.4% of the issued and outstanding shares of Class A Common Stock and 100% of the issued and outstanding shares of Class B Common Stock, which collectively represent 88.1% of the combined voting power of the issued and outstanding shares of Common Stock, immediately upon the consummation of the Transaction, excluding the impact of the issuance of Class A Common Stock as Earnout Shares or Make-Whole Shares (as defined below), as well as additional shares of Class A Common Stock that may become outstanding in the future as a result of the exercise of Chavant’s warrants, the exercise of any warrants convertible from the promissory notes issued by Chavant evidencing the outstanding working capital loans, or any issuance pursuant to the Mobix Labs, Inc. 2023 Equity Incentive Plan or the Mobix Labs, Inc. 2023 Employee Stock Purchase Plan, the exercise of the Assumed Options or the vesting of the Assumed RSUs (collectively, the “Potential Additional Issuances”). Upon the consummation of the Transaction, we expect that the holders of Class B Common Stock, comprised mostly of Mobix Labs’ founders, directors and officers, will own approximately 45.1% of the combined voting power of the issued and outstanding shares of Common Stock of New Mobix Labs and that such holders of Class B Common Stock may exert significant influence on any actions of New Mobix Labs which require stockholder approval.

See the section entitled “The Transaction” on page 235 of this proxy statement/prospectus for further information on the consideration being paid to the equityholders of Mobix Labs in the Transaction.

Assuming no Chavant shareholders exercise redemption rights with respect to their Ordinary Shares in connection with the Transaction, the holders of Ordinary Shares issued in Chavant’s initial public offering, the Initial Shareholders (as defined herein) (which holders are Chavant’s sponsor, Chavant Capital Partners LLC (the “Sponsor”), the directors or officers of Chavant and certain designees of the Representatives (as defined herein)) and the PIPE Investor (as defined herein) are expected to hold in the aggregate approximately 2.9%, 7.5% and 11.2%, respectively, of the issued and outstanding shares of Class A Common Stock (assuming no redemptions by the Public Shareholders), which represent 1.6%, 4.1%, and 6.2%, respectively, of the combined voting power of the issued and outstanding shares of Common Stock, immediately upon the consummation of the Transaction, excluding the impact of the Potential Additional Issuances.

In connection with the execution of the Business Combination Agreement, Chavant entered into a subscription agreement (the “PIPE Subscription Agreement”) with an accredited investor (the “PIPE Investor”), pursuant to which the PIPE Investor agreed to purchase 3,000,000 shares of Class A Common Stock at a price of $10.00 per share for an aggregate amount of $30 million, substantially concurrently with the closing of the Transaction, on the terms and subject to the conditions of the PIPE Subscription Agreement. Pursuant to the PIPE Subscription Agreement, Chavant agreed to file a registration statement registering the resale of the shares of Class A Common Stock acquired by the PIPE Investor (the “PIPE Resale Registration Statement”) within 45 days of Closing.

Pursuant to the PIPE Subscription Agreement, Chavant agreed to issue additional shares of Class A Common Stock to the PIPE Investor in the event that the volume weighted average price per share of the Class A Common Stock during the 30-day period (the “Adjustment Period”) commencing on the date that is 30 days after the date on which the PIPE Resale Registration Statement is declared effective (the “Adjustment Period VWAP”) is less than $10.00 per share. In such case, the PIPE Investor will be entitled to receive a number of shares of Class A Common Stock equal to the product of (x) the number of shares of Class A Common Stock issued to the PIPE Investor at the closing of the subscription and held by the PIPE Investor through the end of the Adjustment Period multiplied by (y) a fraction, (A) the numerator of which is $10.00 minus the Adjustment Period VWAP and (B) the denominator of which is the Adjustment Period VWAP (the “Make-Whole Shares”). In the event that the Adjustment Period VWAP is less than $7.00, the Adjustment Period VWAP will be deemed to be $7.00.

Chavant’s Units, Ordinary Shares and Warrants are currently listed on The Nasdaq Capital Market, under the symbols “CLAYU,” “CLAY,” and “CLAYW,” respectively. Chavant intends to apply to continue the listing of the shares of Class A Common Stock and warrants of New Mobix Labs on The Nasdaq Capital Market under the symbols “MOBX” and “MOBXW”, respectively, upon the Closing. New Mobix Labs will not have units traded upon the consummation of the Transaction, at which time each unit will separate into its component Class A Common Stock and Warrant. On [ ], 2023, the trading date immediately prior to the date of this proxy statement/prospectus, the Units, Ordinary Shares and Public Warrants closed at $[            ], $[              ] and $[             ], respectively.

Chavant is holding an extraordinary general meeting in lieu of an annual general meeting in order to obtain the shareholder approval necessary to complete the Transaction. At the Chavant extraordinary general meeting, which will be held on [            ], 2023, at [            ], Eastern Time, unless postponed or adjourned to a later date, Chavant will ask its shareholders to adopt the Business Combination Agreement, thereby approving the Transaction, including the Domestication, and approve the other proposals described in this proxy statement/prospectus. The physical location of the meeting is at the offices of Simpson Thacher & Bartlett LLP located at 425 Lexington Avenue, New York, New York 10017, United States of America.

As described in this proxy statement/prospectus, certain holders of a requisite number of the outstanding shares of Mobix Labs common stock and Mobix Labs preferred stock have delivered written consents sufficient to approve and adopt the Business Combination Agreement and the Transaction. Therefore, no additional approval or vote from any holders of any class or series of stock of Mobix Labs will be necessary to approve the Transaction.

After careful consideration, the Chavant board of directors has unanimously approved the Business Combination Agreement and the Transaction, has determined that it is advisable to consummate the Transaction and has approved the other proposals described in this proxy statement/prospectus. The Chavant board of directors recommends that its shareholders vote “FOR” the proposals described in this proxy statement/prospectus.

More information about Chavant, Mobix Labs and the Transaction is contained in this proxy statement/prospectus.

The Transaction Proposal, the Advisory Governance Proposals, the Nasdaq Proposal, the Director Election Proposal, the Equity Incentive Plan Proposal, the Employee Stock Purchase Plan Proposal and the Adjournment Proposal must be approved by an ordinary resolution as a matter of Cayman Islands law, being the affirmative vote of the holders of a majority of the Chavant ordinary shares, who, being present in person (including virtually), or represented by proxy and entitled to vote at the Special Meeting, vote at the Special Meeting. The Advisory Governance Proposals are voted upon on a non-binding advisory basis only. The Domestication Proposal and the Organizational Documents Proposal require the approval of a special resolution under Cayman Islands law, being the affirmative vote of the holders of a majority of at least two-thirds of the Chavant ordinary shares who, being present in person (including virtually) or represented by proxy and entitled to vote at the Special Meeting, vote at the Special Meeting. The approval of each Condition Precedent Proposal is conditioned on the approval of all of the other Condition Precedent Proposals. If any of the Condition Precedent Proposals fails to receive the required approval by the Chavant shareholders at the Special Meeting, the Transaction will not be completed.

In connection with the execution of the Business Combination Agreement, the Sponsor (the ordinary shares initially purchased by Sponsor in connection with the initial public offering, the “Founder Shares”) and the director and officer holders of Chavant entered into a sponsor letter agreement (the “Sponsor Letter Agreement”) with Chavant and Mobix Labs, pursuant to which, among other things, the Sponsor and the directors and officers of Chavant agreed to vote all of their Chavant ordinary shares and Warrants in favor of the Transaction, the Condition Precedent Proposals and all the other proposals the parties deem necessary or desirable to effect the Transaction. In addition, in connection with Chavant’s initial public offering, the initial holders of ordinary shares and Warrants of Chavant, including the Sponsor, the directors and officers of Chavant, and the permitted designees of Roth Capital Partners, LLC and Craig-Hallum Capital Group LLC, which were representatives of the underwriters in the initial public offering (collectively with the Sponsor and the officers and directors, the “Initial Shareholders”), entered into a letter agreement with Chavant, pursuant to which they agreed to vote all their Chavant ordinary shares in favor of the Transaction. Chavant expects that the Initial Shareholders will vote their shares in favor of all of the Proposals being presented at the Special Meeting. The Initial Shareholders currently collectively own approximately 72.0% of the outstanding Chavant ordinary shares.

Each of these Proposals is more fully described in the accompanying proxy statement/prospectus, which we encourage you to read carefully and in its entirety before voting. Only holders of Chavant ordinary shares entered in the register of members of Chavant at the close of business on [             ], 2023 are entitled to notice of the Special Meeting and to vote and have their votes counted at the Special Meeting and any adjournments or postponements thereof. As of the record date, there were [             ] Chavant ordinary shares issued and outstanding and entitled to vote.

YOUR VOTE IS VERY IMPORTANT. PLEASE VOTE YOUR SHARES PROMPTLY.

Whether or not you plan to participate in the virtual Special Meeting, please complete, date, sign and return the enclosed proxy card without delay, or submit your proxy through the internet or by telephone as promptly as possible in order to ensure your representation at the Special Meeting no later than the time appointed for the Special Meeting or adjourned meeting. Voting by proxy will not prevent you from voting your Chavant ordinary shares online if you subsequently choose to participate in the virtual Special Meeting. Please note, however, that if your shares are held of record by a broker, bank or other agent and you wish to vote at the Special Meeting, you must obtain a proxy issued in your name from that record. Only shareholders entered in the register of members of Chavant at the close of business on the record date may vote at the Special Meeting or any adjournment or postponement thereof. If you fail to return your proxy card or fail to instruct your bank, broker or other nominee how to vote, and do not participate in the virtual Special Meeting, your shares will not be counted for purposes of determining whether a quorum is present at, and the number of votes voted at, the Special Meeting.

You may revoke a proxy at any time before it is voted at the Special Meeting by executing and returning a proxy card dated later than the previous one, by participating in the Special Meeting and casting your vote by hand or by ballot (as applicable) or by submitting a written revocation to Morrow Sodali LLC, toll-free: (800) 662-5200, collect: (203) 658-9400, email: CLAY.info@investor.morrowsodali.com, that is received by the proxy solicitor before we take the vote at the Special Meeting. If you hold your shares through a bank or brokerage firm, you should follow the instructions of your bank or brokerage firm regarding revocation of proxies.

The Chavant board of directors unanimously recommends that Chavant shareholders vote “FOR” approval of each of the Proposals. When you consider the Chavant board of directors’ recommendation of these Proposals, you should keep in mind that Chavant’s directors and officers have interests in the Transaction that may conflict or differ from your interests as a shareholder. See the section titled “Proposal No. 1 — The Transaction Proposal — Interests of Certain Persons in the Transaction.”

On behalf of the Chavant board of directors, I thank you for your support and we look forward to the successful consummation of the Transaction.

​

If you return your signed proxy without an indication of how you wish to vote, your shares will be voted in favor of each of the Proposals.

All holders (the “Public Shareholders”) of Chavant’s Ordinary Shares issued in the Chavant IPO (as defined herein) (the “Public Shares”) have the right to have their Public Shares redeemed for cash in connection with the proposed Transaction. Public Shareholders are not required to affirmatively vote for or against the Transaction Proposal, to vote on the Transaction Proposal at all, or to be holders of record on the record date in order to have their shares redeemed for cash. This means that any Public Shareholder holding Public Shares may exercise redemption rights regardless of whether they are even entitled to vote on the Transaction Proposal.

To exercise redemption rights, holders of Public Shares must tender their shares to Continental Stock Transfer & Trust Company, Chavant’s transfer agent, no later than two (2) business days prior to the Special Meeting. You may tender your shares by either delivering your share certificate to the transfer agent or by delivering your shares electronically using the Depository Trust Company’s Deposit Withdrawal at Custodian System. If the Transaction is not completed, then these shares will not be redeemed for cash. If you hold the shares in street name, you will need to instruct your bank or broker to withdraw the shares from your account in order to exercise your redemption rights. See “Extraordinary General Meeting — Redemption Rights” in the accompanying proxy statement/prospectus for more specific instructions.

ABOUT THIS PROXY STATEMENT/PROSPECTUS

This document, which forms part of a registration statement on Form S-4 filed with the U.S. Securities and Exchange Commission by Chavant (File No. 333-271197), constitutes a prospectus of Chavant under Section 5 of the Securities Act of 1933, as amended, with respect to the securities to be issued if the Transaction described below is consummated, including to Chavant shareholders and to holders of Mobix Labs Common Stock other than the Consenting Mobix Labs Stockholders. This document also constitutes a notice of meeting and a proxy statement under Section 14(a) of the U.S. Securities Exchange Act of 1934, as amended with respect to the Special Meeting in lieu of the 2023 annual general meeting of Chavant shareholders at which shareholders of Chavant will be asked to consider and vote upon a proposal to approve the Transaction by the approval and adoption of the Business Combination Agreement, among other matters. This document does not serve as a prospectus for the shares of Class A Common Stock or Class B Common Stock that the Consenting Mobix Labs Stockholders will receive in the Transaction.

ENFORCEABILITY OF CIVIL LIABILITIES

We are a company incorporated under the laws of the Cayman Islands. Our chief executive officer, Dr. Jiong Ma, acts as our U.S. agent for service of process designated under the federal securities laws at the address of the office space we use from our Sponsor at 445 Park Avenue, 9th Floor, New York, NY 10022. However, some of our directors reside outside of the United States, and it may be difficult for investors to effect service of process on those directors within the United States.

Our corporate affairs will be governed by our Existing Charter, the Cayman Islands Companies Act, and the common law of the Cayman Islands prior to the Domestication. The rights of shareholders to take action against the directors, actions by minority shareholders and the fiduciary responsibilities of our directors to us under Cayman Islands law are to a large extent governed by the Cayman Islands Companies Act and the common law of the Cayman Islands. The common law of the Cayman Islands is derived in part from comparatively limited judicial precedent in the Cayman Islands, as well as from English common law, the decisions of whose courts are considered persuasive authority but are not binding on a court in the Cayman Islands. The rights of our shareholders and the fiduciary responsibilities of our directors under Cayman Islands law are not as clearly established as they would be under statutes or judicial precedent in some jurisdictions in the United States. In particular, the Cayman Islands has a less developed body of securities laws as compared to the United States, and some states, such as Delaware, have more fully developed and judicially interpreted bodies of corporate law. In addition, Cayman Islands companies may not have standing to initiate a shareholder derivative action in a federal court of the United States.

The Cayman Islands courts are also unlikely:

We have been advised by Maples and Calder (Cayman) LLP, our Cayman Islands legal counsel, that there is no statutory recognition in the Cayman Islands of judgments obtained in the United States, although the courts of the Cayman Islands will in certain circumstances recognize and enforce a non-penal judgment of a foreign court and treat it as a cause of action in itself which may be sued upon as a debt at common law so that no retrial of the issues would be necessary, provided that: (i) the U.S. court issuing the judgment had jurisdiction in the matter and the company either submitted to such jurisdiction or was resident or carrying on business within such jurisdiction and was duly served with process; (ii) the judgment given by the U.S. court was not in respect of penalties, taxes, fines or similar fiscal or revenue obligations of the company; (iii) in obtaining judgment there was no fraud on the part of the person in whose favor judgment was given or on the part of the court; (iv) recognition or enforcement of the judgment would not be contrary to public policy in the Cayman Islands; and (v) the proceedings pursuant to which judgment was obtained were not contrary to natural justice. In appropriate circumstances, a Cayman Islands court may give effect in the Cayman Islands to other kinds of final foreign judgments such as declaratory orders, orders for performance of contracts and injunctions.

As a result of all of the above, Public Shareholders may have more difficulty in protecting their interests in the face of actions taken by management, members of the board of directors or controlling shareholders than they would as public shareholders of a U.S. company.

Q.Why is Chavant proposing the Transaction Proposal?

Chavant received $80,000,000 in net proceeds from the sale of the Units in the Chavant IPO and sale of the Private Warrants, which was placed into the Trust Account immediately following the Chavant IPO. At an extraordinary general meeting held on July 14, 2022, Chavant shareholders were asked to approve a proposal to amend Chavant’s charter (the “First Extension Amendment”) to extend the date by which Chavant must consummate an initial business combination from July 22, 2022 to January 22, 2023. The proposal was approved and certain Chavant shareholders holding 7,046,967 Ordinary Shares exercised their right to redeem their shares for a pro rata portion of the funds in the Trust Account. As a result, $70,573,278 (approximately $10.01 per share) was deducted from the Trust Account to pay such holders. In connection with the First Extension Amendment,

Chavant agreed to deposit $31,450 (at a rate of $0.033 per non-redeeming Public Share) for each subsequent monthly period needed by Chavant to complete a business combination by January 22, 2023.

At a second extraordinary general meeting on January 6, 2023, Chavant shareholders were asked to approve a further extension of the date by which Chavant must consummate an initial business combination (the “Second Extension Amendment”) from January 22, 2023 to July 22, 2023. The proposal was approved, and certain Chavant shareholders holding 96,991 Ordinary Shares exercised their right to redeem their shares for a pro rata portion of the funds in the Trust Account. As a result, $1,004,600 (approximately $10.36 per share) was deducted from the Trust Account to pay such holders. In connection with the Second Extension Amendment, Chavant agreed to deposit $42,802 (at a rate of $0.05 per non-redeeming Public Share) for each subsequent monthly period needed by Chavant to complete a business combination by July 22, 2023. At a third extraordinary general meeting on July 18, 2023, Chavant shareholders were asked to approve a further extension of the date by which Chavant must consummate an initial business combination (the “Third Extension Amendment”) from July 22, 2023 to January 22, 2024. The proposal was approved, and certain Chavant shareholders holding 77,130 Ordinary Shares exercised their right to redeem their shares for a pro rata portion of the funds in the Trust Account. As a result, $841,807 (approximately $10.91 per share) was deducted from the Trust Account to pay such holders. In connection with the Third Extension Amendment, Chavant agreed to deposit $38,946 (at a rate of $0.05 per non-redeeming Public Share) for each subsequent monthly period needed by Chavant to complete a business combination by January 22, 2024. Following the redemptions of the Public Shares described above, the 2,000,000 Founder Shares that remain outstanding represented 72.0% of the Company’s issued and outstanding ordinary shares.

As of September 30, 2023, the Trust Account had a total balance of approximately $8,676,157. In accordance with Chavant’s Existing Charter, the funds held in the Trust Account will be released upon the consummation of the Transaction. See the question entitled “What happens to the funds held in the Trust Account upon the consummation of the Transaction?”

Chavant’s Board has unanimously approved the Transaction and is recommending the Transaction to Chavant’s shareholders for a variety of reasons. Please see the section titled “The Transaction — Chavant’s Board of Directors’ Reasons for the Approval of the Transaction” for additional information.

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, while considered present for the purposes of establishing a quorum, will not count as a vote cast at the Special Meeting.

​

Chavant does not expect to have significant cumulative earnings and profits, if any, on the date of the Domestication. As discussed more fully under “Material U.S. Federal Income Tax Considerations,” Chavant believes that it is likely classified as a PFIC for U.S. federal income tax purposes. In such case, notwithstanding the U.S. federal income tax consequences of the Domestication discussed above, 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 on the exchange of Ordinary Shares or Warrants for Class A Common Stock or Warrants pursuant to the Domestication. Any such gain would be taxable income with no corresponding receipt of cash in the Domestication. The tax on any such gain would be imposed at the rate applicable to ordinary income and an interest charge would apply based on a complex set of rules. In addition, the proposed Treasury Regulations provide coordinating rules with other sections of the Code, including Section 367(b), which affect the manner in which the rules under such other sections apply to transfers of PFIC stock. 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 may be adopted and how any such Treasury Regulations would apply. Importantly, however, U.S. Holders that make or have made certain elections discussed further under “Material U.S. Federal Income Tax Considerations” with respect to their Ordinary Shares generally are not subject to the same gain recognition rules under the currently proposed Treasury Regulations under Section 1291(f) of the Code. Currently, there are no elections available that apply to the Warrants, and the application of the PFIC rules to the Warrants is unclear. For a more complete discussion of the potential application of the PFIC rules to U.S. Holders as a result of the Domestication, see the section entitled “Material U.S. Federal Income Tax Considerations.”

Each U.S. Holder of Ordinary Shares or Warrants is urged to consult its own tax advisor concerning the application of the PFIC rules, including the proposed Treasury Regulations, to the exchange of Ordinary Shares and Warrants for Class A Common Stock and Warrants pursuant to the Domestication.

Additionally, the Domestication may cause non-U.S. Holders to become subject to U.S. federal income withholding taxes on any amounts treated as dividends paid in respect of such non-U.S. Holder’s Class A Common Stock after the Domestication.

The tax consequences of the Domestication are complex and will depend on a holder’s particular circumstances. All holders are urged to consult their tax advisors regarding the tax consequences to them of the Domestication, including the applicability and

effect of U.S. federal, state, local and non-U.S. tax laws. For a more complete discussion of the U.S. federal income tax considerations of the Domestication, see the section entitled “Material U.S. Federal Income Tax Considerations.”

shareholders to extend the deadline for Chavant to consummate an initial business combination, then Chavant will be required to wind up, dissolve and liquidate.

The existence of financial and personal interests of Chavant’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 or officer’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 January 22, 2024, we may be forced to liquidate, and the 1,580,813 Founder Shares and 2,794,332 Private Warrants owned by our Sponsor, and 1,706,031 Founder Shares beneficially owned by our directors and officers, would be worthless. See the sections entitled “Summary of the Proxy Statement/Prospectus — Interests of Certain Persons in the Transaction” for more information.

A.At the Effective Time, by virtue of the Merger:

Additionally, effective as of the Effective Time:

The “Per Share Exchange Ratio” is the number obtained by dividing 23,500,000 by the fully diluted number of shares of Mobix Labs immediately prior to the Effective Time, which reflects the aggregate number of shares of Mobix Labs Common Stock issued and outstanding immediately prior to the Effective Time, the aggregate number of shares of Mobix Labs Common Stock into which the shares of Mobix Labs Preferred Stock could be converted (without regard to whether such shares of Mobix Labs Preferred Stock may then be converted in accordance with the Mobix Labs Charter), the aggregate number of shares of Mobix Labs Common Stock issuable upon exercise of outstanding options and warrants to purchase Mobix Labs Common Stock and Mobix Labs Convertible Instruments that convert into Mobix Labs Common Stock or shares of Mobix Labs Preferred Stock, and the aggregate number of shares of Mobix Labs Common Stock issuable upon vesting and settlement of outstanding Mobix Labs RSUs, which fully diluted number excludes the shares of Post-March 26 Financing Securities. “Closing Transaction Consideration” means the Aggregate Transaction Consideration minus the Earnout Shares. “Aggregate Transaction Consideration” means a number of shares of Common Stock equal to (a) the quotient obtained by dividing (i) the assumed value of Mobix Labs in an amount equal to $235 million by (ii) $10.00 plus (b) a number of shares of Class A Common Stock equal to (i) the Per Share Exchange Ratio multiplied by (ii) the number of shares of Post-March 26 Financing Securities plus (c) the number of shares of Class A Common Stock comprising the Earnout Shares. The estimated maximum number of additional shares that may be issued in exchange for the Post-March 26 Financing Securities is 3,000,000, and this estimate is provided solely for the purpose of registering a maximum amount of shares under the registration statement on Form S-4 of which this proxy statement/prospectus forms a part. As of October 31, 2023, the number of additional shares of Class A Common Stock that would be issued in exchange for the Post- March 26 Financing Securities is 2,765,886.

If a Public Shareholder exercises its redemption rights, such exercise will not result in the loss of any Public Warrants that it may hold. We cannot predict the ultimate value of the Warrants following the consummation of the Transaction, but assuming that all 778,912 Ordinary Shares held by our Public Shareholders were redeemed (maximum redemption scenario), the 6,000,000

retained outstanding Public Warrants would have an aggregate value of $127,200, based on the price per Public Warrant of $0.0212 on October 30, 2023. In addition, on October 30, 2023, the price per Ordinary Share closed at $11.08.

If the Class A Common Stock is trading above the exercise price of $11.50 per warrant, the warrants are considered to be “in the money” and are therefore more likely to be exercised by the holders thereof (when they become exercisable). This in turn increases the risk to the non-redeeming Public Shareholders that the warrants will be exercised, which would result in immediate dilution to the non-redeeming Public Shareholders.

The tables below illustrate the anticipated relative ownership of Public Shareholders, the Initial Shareholders (being the Sponsor, the directors and officers of Chavant and the Representatives’ designees), the PIPE Investor and Mobix Labs equityholders upon completion of the Transaction and the PIPE Private Placement without and after giving effect to the additional dilution that may be caused by the issuance of additional shares in exchange for Post-March 26 Financing Securities, the issuance of Earnout Shares, the issuance of the Make-Whole Shares, the exercise of the outstanding Public Warrants or Private Warrants, the extension of Working Capital Loans under the Chavant Promissory Notes and the exercise of any Warrants convertible from the Working Capital Loans, any issuance upon the exercise of the Assumed Options or the vesting of the Assumed RSUs or pursuant to the 2023 Equity Incentive Plan or the 2023 Employee Stock Purchase Plan under a no redemption scenario and a maximum redemption scenario. In the no redemption scenario as described below in the sensitivity table, the residual equity value owned by the non-redeeming Public Shareholders is assumed to be the deemed value of $10.00 per share and the implied total equity value of New Mobix Labs following the Transaction, assuming no dilution from any additional dilution sources described in the table below, would be $289.2 million. As a result of the redemption amount in the maximum redemption scenario as described below in the sensitivity table, the implied total equity value of New Mobix Labs following the Transaction, assuming no dilution from any additional dilution sources described in the table below, would be $281.4 million in the maximum redemption scenario. These amounts are based solely on an assumed value of $10.00 per share and do not reflect a third-party valuation nor a prediction of the future value of the Mobix Labs Common Stock. Additionally, the sensitivity table below sets forth the potential additional dilutive impact of each of the additional dilution sources in each redemption scenario, as described further in Notes 10 through 18 below. Stockholders will experience additional dilution to the extent New Mobix Labs issues any such additional shares after the Closing.

​

Post-Redemptions in the No Redemption Scenario and the Maximum Redemption Scenario plus the full exercise of the applicable maximum number of Warrants at $11.50 per share for a total cash exercise price of $69 million in the row entitled “Public Warrants,” $39.1 million in the row entitled “Private Warrants,” or $17.25 million in the row entitled “Working Capital Loans,” respectively.

The numbers of shares and percentage interests set forth in the tables above are based on a number of assumptions described in the footnotes to the tables and that neither Chavant nor Mobix Labs issues any additional equity securities prior to the Transaction. If the actual facts differ from our assumptions, the numbers of shares and percentage interests set forth above will be different.

Q.Will Chavant obtain new financing in connection with the Transaction?

Pursuant to the PIPE Subscription Agreement, Chavant agreed to issue the Make-Whole Shares to the PIPE Investor in the event that the Adjustment Period VWAP is less than $10.00 per share (as adjusted for any stock split, reverse stock split or similar adjustment following the Closing). In such case, the PIPE Investor will be entitled to receive a number of Make-Whole Shares equal to the product of (x) the number of shares of Class A Common Stock issued to the PIPE Investor at the closing of the subscription and held by the PIPE Investor through the end of a 30-day period that begins on the date that is 30 days after the effective date of the PIPE Resale Registration Statement multiplied by (y) a fraction, (A) the numerator of which is $10.00 (as adjusted for any stock split, reverse stock split or similar adjustment following the Closing) minus the Adjustment Period VWAP and (B) the denominator of which is the Adjustment Period VWAP. In the event that the Adjustment Period VWAP is less than $7.00, the Adjustment Period VWAP will be deemed to be $7.00.

For more information about the PIPE Subscription Agreement, see the section entitled “Certain Agreements Related to the Transaction — PIPE Subscription Agreement.”

In addition, in connection with the Transaction and subject to the terms in the Business Combination Agreement, both Chavant and Mobix Labs have agreed to use commercially reasonable efforts to conduct and complete additional Financing Arrangements, including private placements of securities of Chavant and Mobix Labs or similar financing arrangements.

Q.Who will be the officers and directors of the Company if the Transaction is consummated?

Immediately following the consummation of the Transaction, Chavant expects that the current senior management of Mobix Labs will comprise the senior management of New Mobix Labs.

See “Management of New Mobix Labs After the Transaction” for additional information.

To the extent any such purchases by the Sponsor, Chavant’s directors, officers, advisors or any of their respective affiliates are made in situations in which the tender offer rules restrictions on purchases apply, Chavant will disclose in a Current Report on Form 8-K prior to the Special Meeting the following: (i) the number of Public Shares purchased outside of the redemption offer, along with the purchase price(s) for such Public Shares; (ii) the purpose of any such purchases; (iii) the impact, if any, of the purchases on the likelihood that the Condition Precedent Proposals will be approved; (iv) the identities of the equityholders who sold to the Sponsor, Chavant’s directors, officers, advisors or any of their respective affiliates (if not purchased on the open market) or the nature of the equityholders (e.g., 5% security holders) who sold such Public Shares; and (v) the number of Public Shares for which Chavant has received redemption requests pursuant to its redemption offer.

The purpose of such share purchases and other transactions would be to increase the likelihood of limiting the number of Public Shares electing to redeem.

If such transactions are effected, the consequence could be to cause the Condition Precedent Proposals to be approved in circumstances where such approval could not otherwise occur. Consistent with guidance of the SEC, purchases of shares by the persons described above would not be permitted to be voted for the Condition Precedent Proposals at the Special Meeting and could decrease the chances that the Condition Precedent Proposals would be approved. In addition, if such purchases are made, the public “float” of Chavant’s securities and the number of beneficial holders of Chavant’s securities may be reduced, possibly making it difficult to maintain or obtain the quotation, listing or trading of Chavant’s securities on a national securities exchange.

Chavant hereby represents that any public shares purchased by the Sponsor, its directors, officers, advisors or any of their respective affiliates in situations in which the tender offer rules restrictions on purchases would apply would not be voted in favor of approving the Condition Precedent Proposals.

In addition, with respect to the members of management of Mobix Labs who have been nominated to serve on the New Mobix Labs Board in connection with the Transaction, you should review the information set forth under “Mobix Labs’ Executive Compensation” and “Security Ownership of Certain Beneficial Owners and Management of New Mobix Labs.”

Any request for redemption, once made by a holder of Public Shares, may be withdrawn at any time prior to the time the vote is taken with respect to the Transaction Proposal at the Special Meeting. If you deliver your shares for redemption to Chavant’s

transfer agent and later decide prior to the Special Meeting not to elect redemption, you may request that Chavant’s transfer agent return the shares (physically or electronically). You may make such request by contacting Chavant’s transfer agent at the address listed under the question “Who can help answer my questions?” below.

Any written demand of redemption rights must be received by Chavant’s transfer agent at least two (2) business days prior to the vote taken on the Transaction Proposal at the Special Meeting. No demand for redemption will be honored unless the holder’s shares (and share certificates (if any) and other redemption forms) have been tendered or delivered (either physically or electronically) to the transfer agent.

If you are a holder of Public Shares (including through the ownership of Units) and you exercise your redemption rights, it will not result in the loss of any Warrants that you may hold (including those contained in any Units you hold). Your Warrants will become exercisable to purchase one share of Class A Common Stock for a purchase price of $11.50 beginning 30 days after consummation of the Transaction.

Additionally, because the Domestication will occur immediately prior to the redemption of any Public Shareholder, U.S. Holders exercising redemption rights will be subject to the potential tax consequences of Section 367 of the Code as well as potential tax consequences of the U.S. federal income tax rules relating to PFICs. The tax consequences of Section 367 of the Code and the PFIC rules are discussed more fully below under “Material U.S. Federal Income Tax Considerations.”

All holders considering exercising redemption rights are urged to consult their tax advisor on the tax consequences to them of an exercise of redemption rights, including the applicability and effect of U.S. federal, state, local and non-U.S. tax laws.

Q.If I hold Units, can I exercise redemption rights with respect to my Units?

Q.What happens to the funds held in the Trust Account upon the consummation of the Transaction?

Transaction, to the extent not otherwise paid prior to the Closing. Any additional funds available for release from the Trust Account will be used for working capital and general corporate purposes of New Mobix Labs following the Transaction.

Chavant’s Existing Charter does not provide a specified maximum redemption threshold.

If, as a result of the termination of the Business Combination Agreement or otherwise, Chavant is unable to complete a business combination by January 22, 2024 or obtain the approval of Chavant shareholders to extend the timeline for Chavant to consummate an initial business combination, Chavant’s Existing Charter provides that Chavant 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 all 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 interest earned on the funds held in the Trust Account (less taxes payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of Chavant’s remaining shareholders and Chavant’s board of directors, liquidate and dissolve, subject, in each case, to Chavant’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. See the sections entitled “Risk Factors — Risks Related to Chavant and the Transaction — We may not be able to consummate an initial business combination by January 22, 2024, in which case we would cease all operations except for the purpose of winding up, and we would redeem our Public Shares and liquidate” and “— Our shareholders may be held liable for claims by third parties against us to the extent of distributions received by them upon redemption of their shares.” The Initial Shareholders have waived any right to any liquidation distribution with respect to their Ordinary Shares.

In the event of liquidation, there will be no distribution with respect to outstanding Warrants, and the Warrants will expire worthless.

For a description of the conditions to the completion of the Transaction, see the section entitled “Proposal No. 1 — The Transaction Proposal — The Business Combination Agreement — Conditions to Closing.”
