NOTE 1 — ORGANIZATION AND BUSINESS OPERATIONS	NOTE 1 — ORGANIZATION AND BUSINESS OPERATIONS *Organization and General* Onyx Acquisition Co. I (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on February 2, 2021. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of March 31, 2024, the Company had not commenced any operations. All activity for the period from February 2, 2021 (inception) through March 31, 2024 relates to the Company’s formation, initial public offering (“IPO”), which is described below, and the search for a target with which to consummate a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on a demand deposit held in the Trust Account (as defined below). The Company has selected December 31 as its fiscal year end. *Sponsor and Financing* The Company’s sponsor is Onyx Acquisition Sponsor Co. LLC, a Cayman Islands limited liability company (the “Sponsor”). On November 5, 2021, the Company consummated its IPO of 26,450,000 units (the “Units”). Each Unit consists of one Class A ordinary share, $0.0001 par value per share (the “ Class A ordinary shares” and, shares thereof sold in the IPO, the “Public Shares”), and one-half of one redeemable warrant (the “Public Warrants”), each whole Public Warrant entitling the holder thereof to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $264,500,000. Simultaneous with the consummation of the IPO and the issuance and sale of the Units, the Company consummated the private placement of 12,190,000 private placement warrants (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant, generating total proceeds of $12,190,000. The Private Placement Warrants, which were purchased by the Sponsor and BTIG, LLC (“BTIG”), are identical to the Public Warrants, except that if held by the Sponsor or BTIG or their permitted transferees, they are, subject to certain limited exceptions, subject to transfer restrictions until 30 days following the consummation of the Company’s initial Business Combination. Additionally, the Private Placement Warrants held by BTIG are subject to the lock-up and registration rights limitations imposed by Financial Industry Regulatory Authority Rule 5110 and may not be exercised after five years from November 2, 2021. Upon the closing of the IPO and the private placement, $269,790,000 has been placed in a trust account (the “Trust Account”), representing the redemption value of the Class A ordinary shares sold in the IPO, at their redemption value of $10.20 per share. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO and sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. Nasdaq rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the value of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time the Company signs a definitive agreement in connection with the Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. 5 Upon the closing of the IPO and the simultaneous private placement, a total of $269,790,000, consisting of $10.20 per Unit sold in the IPO and a portion of the proceeds from the sale of the Private Placement Warrants, was placed in the Trust Account located in the United States, with Continental Stock Transfer & Trust Company acting as trustee, and invested only in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Pursuant to an investment management trust agreement, the trustee is not permitted to invest in other securities or assets. By restricting the investment of the proceeds to these instruments, and by having a business plan targeted at acquiring and growing businesses for the long term (rather than on buying and selling businesses in the manner of a merchant bank or private equity fund), the Company intends to avoid being deemed an “investment company” within the meaning of the Investment Company Act. The IPO was not intended for persons seeking a return on investments in government securities or investment securities. The Trust Account is intended as a holding place for funds pending the earliest to occur of either: (i) the completion of the initial Business Combination; (ii) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to provide holders of the Class A ordinary shares (the “Public Shareholders”) the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period (as defined below) or (B) with respect to any other provision relating to the rights of holders of the Class A ordinary shares; or (iii) absent the completing an initial Business Combination within the Combination Period, the return of the funds held in the Trust Account to the Public Shareholders as part of the redemption of the Public Shares. If the Company does not invest the proceeds as discussed above, the Company may be deemed to be subject to the Investment Company Act. If the Company is deemed to be subject to the Investment Company Act, compliance with these additional regulatory burdens would require additional expenses for which the Company has not allotted funds and may hinder the ability to complete a Business Combination. If the Company has not consummated the initial Business Combination within the required time period, the Public Shareholders may receive only approximately $10.20 per Public Share, or less than such amount in certain circumstances, on the liquidation of the Trust Account, and the warrants will expire worthless. To avoid being considered an Investment Company, in November 2023, funds in the Trust Account were placed in a demand deposit account. The Company will provide its Public Shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require the Company to seek shareholder approval under applicable law or stock exchange listing requirement. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account. The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 4). These Public Shares were classified as temporary equity upon the completion of the IPO in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Recent Developments On January 18, 2023, the Company issued a press release announcing that it is in advanced discussions with Helios Investment Partners about a potential business combination which would result in the creation of a new publicly listed energy transition infrastructure platform, Helios Energy Transition Infrastructure (“HETI”), focused on the development of natural gas and low-carbon energy infrastructure businesses and assets in Africa (the “Proposed Transaction”). The Proposed Transaction is expected to be valued at an Enterprise Value of approximately $1 billion, and the Company is targeting completion of the merger in the second half of 2024. There is no binding agreement with respect to the Proposed Transaction, and negotiations remain subject to significant contingencies, including the completion of due diligence, the negotiation and execution of a mutually acceptable definitive agreement, confirmation and documentation of fully committed financing, and requisite shareholder approvals. There can be no assurances that the Company will successfully negotiate a definitive agreement, or that the Proposed Transaction will be consummated. The Company will have only until November 5, 2024 to consummate an initial Business Combination (the “Combination Period”). If the Company fails to consummate an initial Business Combination during the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes, if any (less 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 the remaining shareholders and the board of directors, liquidate and dissolve, subject, in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the warrants, which will expire worthless if the Company fails to complete its initial Business Combination within the Combination Period. 6 On January 26, 2023, the Company held an extraordinary general meeting of shareholders (the “First Extension Meeting”) at which the Company’s shareholders approved two proposals to amend the Company’s amended and restated memorandum and articles of association (the “Articles”). The first proposal extended the date by which the Company has to consummate a Business Combination from February 5, 2023 to August 7, 2023 (the “First Extension Amendment Proposal”). The second proposal removed the limitation that the Company shall not redeem Class A ordinary shares included as part of the units sold in its initial public offering (including any shares issued in exchange thereof) to the extent that such redemption would cause the Company’s net tangible assets to be less than $5,000,001 (the “Redemption Limitation Amendment Proposal”). The Extension Amendment Proposal and Redemption Limitation Amendment Proposal are described in more detail in the definitive proxy statement of the Company, which was filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 8, 2022 (the “Proxy Statement”), as supplemented to date. Based on the results of the First Extension Meeting, the Sponsor agreed to contribute (each such contribution, a “Contribution”) into the trust account of the Company (such trust account, the “Trust Account”) the lesser of (x) an aggregate of $120,000 or (y) $0.035 per share for each public share that was not redeemed at the First Extension Meeting for each monthly period until August 7, 2023 (commencing on February 7, 2023 and ending on the 7th day of each subsequent month), or portion thereof, that is needed by the Company to complete its initial Business Combination. The Sponsor and each member of the Company’s management team have agreed to (i) waive their redemption rights with respect to their Founder Shares (as defined below), (ii) waive their redemption rights with respect to their Founder Shares and any Class A ordinary shares in connection with a shareholder vote to approve an amendment to the Company’s Articles (A) that would modify the substance or timing of the Company’s obligation to provide Public Shareholders the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period or (B) with respect to any other provision relating to the rights of Public Shareholders and, (iii) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to consummate an initial Business Combination within the Combination Period (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fail to complete the initial Business Combination within the prescribed time frame), and (iv) vote any Founder Shares held by them and any Public Shares purchased after the IPO (including in the open market and privately-negotiated transactions) in favor of the initial Business Combination. The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third-party (other than the Company’s independent auditor) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below the lesser of (i) $10.20 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.20 per Public Share due to reductions in the value of the trust assets, in each case net of the interest that may be withdrawn to pay the Company’s tax obligations, provided that such liability will not apply to any claims by a third-party or prospective target business that executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third-party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. In connection with the approval of the First Extension Amendment Proposal, holders of 22,239,972 Class A ordinary shares exercised their right to redeem their shares for cash at a redemption price of approximately $10.36 per share, for an aggregate redemption amount of $230,611,860. As a result, such amount was removed from the Trust Account on February 1, 2023 to pay the redeeming holders and 4,210,028 Class A ordinary shares were not redeemed. The remaining amount in the Trust Account immediately following the redemption payments was $42,927,964. On January 26, 2023, in connection with the First Extension Meeting, the holders of the Company’s outstanding Class B ordinary shares (the “founder shares”) converted all of the founder shares into Class A ordinary shares. Notwithstanding the conversions, such holders will not be entitled to receive any monies held in the Trust Account as a result of their ownership of any Class A ordinary shares issued upon conversion of the founder shares. On February 7, 2023, the Company issued a promissory note in the principal amount of up to $720,000 to the Sponsor (the “Extension Note”), evidencing the Company’s indebtedness with respect to the Contributions (the “Extension Loans”). The Extension Loans are unsecured and non-interest bearing, and will be repayable by the Company upon consummation of an initial Business Combination. If the Company does not consummate an initial Business Combination by November 5, 2024, the Extension Note will be repaid only from funds held outside of the Trust Account or will be forfeited, eliminated or otherwise forgiven. On July 21, 2023, the Company held an extraordinary general meeting of shareholders (the “Second Extension Meeting”) at which the Company’s shareholders approved a proposal to amend the Articles. The proposal amended the date by which the Company has to consummate a business combination from August 7, 2023 to February 7, 2024 (the “Second Extension Amendment Proposal”). In connection with the Second Extension Meeting, holders of 2,198,202 Class A ordinary shares exercised their right to redeem their shares for cash at a redemption price of approximately $10.83 per share, for an aggregate redemption amount of $23,802,065. As a result, such amount was removed from the Trust Account to pay such holders and 2,011,826 Class A ordinary shares and 6,612,500 converted founder shares were left outstanding for a total of 8,624,326 Class A ordinary shares outstanding. On October 24, 2023, the Company received a written notice (the “Round Lot Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (the “Staff”) notifying the Company that, since the Company’s Form 10-Q for the period ended June 30, 2023 reported total holders below the round lot holder requirement under Nasdaq Listing Rule 5450(a)(2), the Company no longer complies with Nasdaq’s Listing Rules. On December 7, 2023, the Listing Qualifications Department of the Nasdaq granted the Company an extension to regain compliance with Nasdaq Listing Rule 5450(a)(2) on or before April 22, 2024. On November 3, 2023, the Company amended and restated the Extension Note (hereinafter, the “Restated Note”) increasing the aggregate principal amount to $1,470,000. The Restated Note may be drawn down by the Company from time to time prior to the consummation of an initial Business Combination. The Restated Note does not bear interest, matures on the date of consummation of an initial Business Combination and is subject to customary events of default. As of March 31, 2024, the Company has an outstanding balance of $1,435,000 under the Restated Note. For the three months ended March 31, 2024, the Company purchased an aggregate of $0 in investments in the Trust Account from the monthly Extension Loans. On January 29, 2024, the Company held an extraordinary general meeting of shareholders (the “Third Extension Meeting”) at which the Company’s shareholders approved a proposal to amend the Articles. The proposal extended the date by which the Company has to consummate a Business Combination from February 7, 2024 to November 5, 2024 (the “Third Extension Amendment Proposal,” and, together with the First Extension Amendment Proposal and Second Extension Amendment Proposal, the “Extension Amendment Proposals”). In connection with the Third Extension Meeting, holders of 678,865 Class A ordinary shares exercised their right to redeem their shares for cash at a redemption price of approximately $11.13 per share, for an aggregate redemption amount of approximately $7,600,000. As a result, $7,553,041 was removed from the Trust Account to pay such holders and 1,332,961 Class A ordinary shares (excluding 6,612,500 converted founder shares) remained outstanding, for a total of 7,945,461 shares outstanding. On April 5, 2024, the Company received a written notice (the “MVPHS Notice”) from the Staff notifying the Company that it did not meet the $15,000,000 minimum market value of publicly held shares required to maintain continued listing as set forth in Nasdaq’s Listing Rule 5450(b)(2)(C) (the “MVPHS Rule”) for the 30 -business day period ended April 3, 2024. Under applicable Nasdaq rules, the Company will have 180 calendar days from the date of the MVPHS Notice, or until October 2, 2024, to regain compliance by meeting the continued listing requirements. Specifically, the market value of the Company's publicly held shares must close at $15,000,000 or more for a minimum of 10 consecutive business days. If the Company is unable to regain compliance with the MVPHS Rule by October 2, 2024, the Company will receive written notification from Nasdaq that the Company’s securities are subject to delisting. The Company may, at that time, request a hearing to appeal the delisting determination, which appeal will ordinarily suspend such delisting determination until a decision is issued by Nasdaq subsequent to the hearing. There can be no assurance that any such appeal would be successful. On April 5, 2024, the Company also received a written notice (the “Public Float Notice”) from the Staff, notifying the Company that it no longer met the minimum 1,100,000 publicly held shares required to maintain continued listing as set forth in Nasdaq’s Listing Rule 5450(b)(2)(B) (the “Public Float Standard”). Under applicable Nasdaq rules, the Company will have 45 calendar days to provide Nasdaq a plan to regain compliance with the continued listing requirements, and then, if the plan is accepted, an additional up to 180 calendar days from the date of the Public Float Notice, or until October 2, 2024, to regain compliance with the Public Float Standard. If the plan is not accepted, under Nasdaq Listing Rule 5815(a), the Company may appeal the decision to a Hearings Panel. There can be no assurance that any such appeal would be successful. In connection with the foregoing and the previously disclosed Round Lot Notice, the Company submitted an application for a transfer from the Nasdaq Global Market to the Nasdaq Capital Market on April 8, 2024. On April 26, 2024, the Company received written notice from the Staff stating that the Staff had approved the Company’s application to transfer the listing of its Class A ordinary shares, warrants, and units (the “Company’s Securities”) from the Nasdaq Global Market to the Nasdaq Capital Market. The Class A ordinary shares, warrants, and units will continue to trade under the symbols “ONYX,” “ONYXW,” and “ONYXU,” respectively, and trading of the Company’s Securities will be unaffected by the transfer. The Nasdaq Capital Market operates in substantially the same manner as the Nasdaq Global Market. 7 *Risks and Uncertainties* The continuing military conflict between the Russian Federation and Ukraine, the military action between Hamas and Israel and the risk of escalations of other military conflicts have created and are expected to create global economic consequences. The specific impact on the Company’s financial condition, results of operations, and cash flows is not determinable as of the date of these unaudited condensed financial statements. *Liquidity, Capital Resources and Going Concern* As of March 31, 2024, the Company had cash of $5,744 in its operating bank account and a working capital deficit of $4,036,042. The Company’s liquidity needs up to November 5, 2021 had been satisfied through a payment from the Sponsor of $25,000 (see Note 4) for the Founder Shares to cover certain offering costs and a loan under an unsecured promissory note from the Sponsor of $104,808, which was paid in full on November 18, 2021 (see Note 4). In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor, initial shareholders, officers, directors or their affiliates may, but are not obligated to, provide the Company Working Capital Loans, as defined below (see Note 4). As of March 31, 2024 and December 31, 2023, there were no amounts outstanding under any Working Capital Loans. In February and November 2023, the Company entered into unsecured promissory notes to the Sponsor with an aggregate borrowing capacity of $1,470,000. As of March 31, 2024 and December 31, 2023, the Company has an outstanding balance of $1,435,000 and $1,385,000 under the Restated Note, respectively. Based on the foregoing, management believes that the Company may not have sufficient working capital to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination. The Company is within 12 months of its mandatory liquidation as of the date of filing this Quarterly Report on Form 10-Q. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the mandatory liquidation raises substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the Business Combination or November 5, 2024, the date the Company is required to liquidate. These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern. 8

NOTE 1 — ORGANIZATION AND BUSINESS OPERATIONS

Organization and General

Onyx Acquisition Co. I (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on February 2, 2021. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (the “Business Combination”). The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of March 31, 2024, the Company had not commenced any operations. All activity for the period from February 2, 2021 (inception) through March 31, 2024 relates to the Company’s formation, initial public offering (“IPO”), which is described below, and the search for a target with which to consummate a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income on a demand deposit held in the Trust Account (as defined below). The Company has selected December 31 as its fiscal year end.

Sponsor and Financing

The Company’s sponsor is Onyx Acquisition Sponsor Co. LLC, a Cayman Islands limited liability company (the “Sponsor”).

On November 5, 2021, the Company consummated its IPO of 26,450,000 units (the “Units”). Each Unit consists of one Class A ordinary share, $0.0001 par value per share (the “ Class A ordinary shares” and, shares thereof sold in the IPO, the “Public Shares”), and one-half of one redeemable warrant (the “Public Warrants”), each whole Public Warrant entitling the holder thereof to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment. The Units were sold at an offering price of $10.00 per Unit, generating gross proceeds of $264,500,000.

Simultaneous with the consummation of the IPO and the issuance and sale of the Units, the Company consummated the private placement of 12,190,000 private placement warrants (the “Private Placement Warrants”) at a price of $1.00 per Private Placement Warrant, generating total proceeds of $12,190,000. The Private Placement Warrants, which were purchased by the Sponsor and BTIG, LLC (“BTIG”), are identical to the Public Warrants, except that if held by the Sponsor or BTIG or their permitted transferees, they are, subject to certain limited exceptions, subject to transfer restrictions until 30 days following the consummation of the Company’s initial Business Combination. Additionally, the Private Placement Warrants held by BTIG are subject to the lock-up and registration rights limitations imposed by Financial Industry Regulatory Authority Rule 5110 and may not be exercised after five years from November 2, 2021.

Upon the closing of the IPO and the private placement, $269,790,000 has been placed in a trust account (the “Trust Account”), representing the redemption value of the Class A ordinary shares sold in the IPO, at their redemption value of $10.20 per share.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the IPO and sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. Nasdaq rules provide that the Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the value of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time the Company signs a definitive agreement in connection with the Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination.

Upon the closing of the IPO and the simultaneous private placement, a total of $269,790,000, consisting of $10.20 per Unit sold in the IPO and a portion of the proceeds from the sale of the Private Placement Warrants, was placed in the Trust Account located in the United States, with Continental Stock Transfer & Trust Company acting as trustee, and invested only in United States “government securities” within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Pursuant to an investment management trust agreement, the trustee is not permitted to invest in other securities or assets. By restricting the investment of the proceeds to these instruments, and by having a business plan targeted at acquiring and growing businesses for the long term (rather than on buying and selling businesses in the manner of a merchant bank or private equity fund), the Company intends to avoid being deemed an “investment company” within the meaning of the Investment Company Act. The IPO was not intended for persons seeking a return on investments in government securities or investment securities. The Trust Account is intended as a holding place for funds pending the earliest to occur of either: (i) the completion of the initial Business Combination; (ii) the redemption of any public shares properly tendered in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to provide holders of the Class A ordinary shares (the “Public Shareholders”) the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period (as defined below) or (B) with respect to any other provision relating to the rights of holders of the Class A ordinary shares; or (iii) absent the completing an initial Business Combination within the Combination Period, the return of the funds held in the Trust Account to the Public Shareholders as part of the redemption of the Public Shares. If the Company does not invest the proceeds as discussed above, the Company may be deemed to be subject to the Investment Company Act. If the Company is deemed to be subject to the Investment Company Act, compliance with these additional regulatory burdens would require additional expenses for which the Company has not allotted funds and may hinder the ability to complete a Business Combination. If the Company has not consummated the initial Business Combination within the required time period, the Public Shareholders may receive only approximately $10.20 per Public Share, or less than such amount in certain circumstances, on the liquidation of the Trust Account, and the warrants will expire worthless. To avoid being considered an Investment Company, in November 2023, funds in the Trust Account were placed in a demand deposit account.

The Company will provide its Public Shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require the Company to seek shareholder approval under applicable law or stock exchange listing requirement. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account.

The per-share amount to be distributed to Public Shareholders who redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 4). These Public Shares were classified as temporary equity upon the completion of the IPO in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.”

Recent Developments

On January 18, 2023, the Company issued a press release announcing that it is in advanced discussions with Helios Investment Partners about a potential business combination which would result in the creation of a new publicly listed energy transition infrastructure platform, Helios Energy Transition Infrastructure (“HETI”), focused on the development of natural gas and low-carbon energy infrastructure businesses and assets in Africa (the “Proposed Transaction”).

The Proposed Transaction is expected to be valued at an Enterprise Value of approximately $1 billion, and the Company is targeting completion of the merger in the second half of 2024. There is no binding agreement with respect to the Proposed Transaction, and negotiations remain subject to significant contingencies, including the completion of due diligence, the negotiation and execution of a mutually acceptable definitive agreement, confirmation and documentation of fully committed financing, and requisite shareholder approvals. There can be no assurances that the Company will successfully negotiate a definitive agreement, or that the Proposed Transaction will be consummated.

The Company will have only until November 5, 2024 to consummate an initial Business Combination (the “Combination Period”). If the Company fails to consummate an initial Business Combination during the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to the Company to pay income taxes, if any (less 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 the remaining shareholders and the board of directors, liquidate and dissolve, subject, in the case of clauses (ii) and (iii), to the Company’s obligations under Cayman Islands law to provide for claims of creditors and in all cases subject to the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the warrants, which will expire worthless if the Company fails to complete its initial Business Combination within the Combination Period.

On January 26, 2023, the Company held an extraordinary general meeting of shareholders (the “First Extension Meeting”) at which the Company’s shareholders approved two proposals to amend the Company’s amended and restated memorandum and articles of association (the “Articles”). The first proposal extended the date by which the Company has to consummate a Business Combination from February 5, 2023 to August 7, 2023 (the “First Extension Amendment Proposal”). The second proposal removed the limitation that the Company shall not redeem Class A ordinary shares included as part of the units sold in its initial public offering (including any shares issued in exchange thereof) to the extent that such redemption would cause the Company’s net tangible assets to be less than $5,000,001 (the “Redemption Limitation Amendment Proposal”). The Extension Amendment Proposal and Redemption Limitation Amendment Proposal are described in more detail in the definitive proxy statement of the Company, which was filed with the U.S. Securities and Exchange Commission (the “SEC”) on December 8, 2022 (the “Proxy Statement”), as supplemented to date.

Based on the results of the First Extension Meeting, the Sponsor agreed to contribute (each such contribution, a “Contribution”) into the trust account of the Company (such trust account, the “Trust Account”) the lesser of (x) an aggregate of $120,000 or (y) $0.035 per share for each public share that was not redeemed at the First Extension Meeting for each monthly period until August 7, 2023 (commencing on February 7, 2023 and ending on the 7th day of each subsequent month), or portion thereof, that is needed by the Company to complete its initial Business Combination.

The Sponsor and each member of the Company’s management team have agreed to (i) waive their redemption rights with respect to their Founder Shares (as defined below), (ii) waive their redemption rights with respect to their Founder Shares and any Class A ordinary shares in connection with a shareholder vote to approve an amendment to the Company’s Articles (A) that would modify the substance or timing of the Company’s obligation to provide Public Shareholders the right to have their shares redeemed in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period or (B) with respect to any other provision relating to the rights of Public Shareholders and, (iii) waive their rights to liquidating distributions from the Trust Account with respect to their Founder Shares if the Company fails to consummate an initial Business Combination within the Combination Period (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fail to complete the initial Business Combination within the prescribed time frame), and (iv) vote any Founder Shares held by them and any Public Shares purchased after the IPO (including in the open market and privately-negotiated transactions) in favor of the initial Business Combination.

The Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third-party (other than the Company’s independent auditor) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below the lesser of (i) $10.20 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.20 per Public Share due to reductions in the value of the trust assets, in each case net of the interest that may be withdrawn to pay the Company’s tax obligations, provided that such liability will not apply to any claims by a third-party or prospective target business that executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the indemnity of the underwriters of the IPO against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third-party, the Sponsor will not be responsible to the extent of any liability for such third-party claims.

In connection with the approval of the First Extension Amendment Proposal, holders of 22,239,972 Class A ordinary shares exercised their right to redeem their shares for cash at a redemption price of approximately $10.36 per share, for an aggregate redemption amount of $230,611,860. As a result, such amount was removed from the Trust Account on February 1, 2023 to pay the redeeming holders and 4,210,028 Class A ordinary shares were not redeemed. The remaining amount in the Trust Account immediately following the redemption payments was $42,927,964.

On January 26, 2023, in connection with the First Extension Meeting, the holders of the Company’s outstanding Class B ordinary shares (the “founder shares”) converted all of the founder shares into Class A ordinary shares. Notwithstanding the conversions, such holders will not be entitled to receive any monies held in the Trust Account as a result of their ownership of any Class A ordinary shares issued upon conversion of the founder shares.

On February 7, 2023, the Company issued a promissory note in the principal amount of up to $720,000 to the Sponsor (the “Extension Note”), evidencing the Company’s indebtedness with respect to the Contributions (the “Extension Loans”). The Extension Loans are unsecured and non-interest bearing, and will be repayable by the Company upon consummation of an initial Business Combination. If the Company does not consummate an initial Business Combination by November 5, 2024, the Extension Note will be repaid only from funds held outside of the Trust Account or will be forfeited, eliminated or otherwise forgiven.

On July 21, 2023, the Company held an extraordinary general meeting of shareholders (the “Second Extension Meeting”) at which the Company’s shareholders approved a proposal to amend the Articles. The proposal amended the date by which the Company has to consummate a business combination from August 7, 2023 to February 7, 2024 (the “Second Extension Amendment Proposal”).

In connection with the Second Extension Meeting, holders of 2,198,202 Class A ordinary shares exercised their right to redeem their shares for cash at a redemption price of approximately $10.83 per share, for an aggregate redemption amount of $23,802,065. As a result, such amount was removed from the Trust Account to pay such holders and 2,011,826 Class A ordinary shares and 6,612,500 converted founder shares were left outstanding for a total of 8,624,326 Class A ordinary shares outstanding.

On October 24, 2023, the Company received a written notice (the “Round Lot Notice”) from the Listing Qualifications Department of The Nasdaq Stock Market LLC (the “Staff”) notifying the Company that, since the Company’s Form 10-Q for the period ended June 30, 2023 reported total holders below the round lot holder requirement under Nasdaq Listing Rule 5450(a)(2), the Company no longer complies with Nasdaq’s Listing Rules. On December 7, 2023, the Listing Qualifications Department of the Nasdaq granted the Company an extension to regain compliance with Nasdaq Listing Rule 5450(a)(2) on or before April 22, 2024.

On November 3, 2023, the Company amended and restated the Extension Note (hereinafter, the “Restated Note”) increasing the aggregate principal amount to $1,470,000. The Restated Note may be drawn down by the Company from time to time prior to the consummation of an initial Business Combination. The Restated Note does not bear interest, matures on the date of consummation of an initial Business Combination and is subject to customary events of default. As of March 31, 2024, the Company has an outstanding balance of $1,435,000 under the Restated Note. For the three months ended March 31, 2024, the Company purchased an aggregate of $0 in investments in the Trust Account from the monthly Extension Loans.

On January 29, 2024, the Company held an extraordinary general meeting of shareholders (the “Third Extension Meeting”) at which the Company’s shareholders approved a proposal to amend the Articles. The proposal extended the date by which the Company has to consummate a Business Combination from February 7, 2024 to November 5, 2024 (the “Third Extension Amendment Proposal,” and, together with the First Extension Amendment Proposal and Second Extension Amendment Proposal, the “Extension Amendment Proposals”).

In connection with the Third Extension Meeting, holders of 678,865 Class A ordinary shares exercised their right to redeem their shares for cash at a redemption price of approximately $11.13 per share, for an aggregate redemption amount of approximately $7,600,000. As a result, $7,553,041 was removed from the Trust Account to pay such holders and 1,332,961 Class A ordinary shares (excluding 6,612,500 converted founder shares) remained outstanding, for a total of 7,945,461 shares outstanding.

On April 5, 2024, the Company received a written notice (the “MVPHS Notice”) from the Staff notifying the Company that it did not meet the $15,000,000 minimum market value of publicly held shares required to maintain continued listing as set forth in Nasdaq’s Listing Rule 5450(b)(2)(C) (the “MVPHS Rule”) for the 30 -business day period ended April 3, 2024. Under applicable Nasdaq rules, the Company will have 180 calendar days from the date of the MVPHS Notice, or until October 2, 2024, to regain compliance by meeting the continued listing requirements. Specifically, the market value of the Company's publicly held shares must close at $15,000,000 or more for a minimum of 10 consecutive business days. If the Company is unable to regain compliance with the MVPHS Rule by October 2, 2024, the Company will receive written notification from Nasdaq that the Company’s securities are subject to delisting. The Company may, at that time, request a hearing to appeal the delisting determination, which appeal will ordinarily suspend such delisting determination until a decision is issued by Nasdaq subsequent to the hearing. There can be no assurance that any such appeal would be successful.

On April 5, 2024, the Company also received a written notice (the “Public Float Notice”) from the Staff, notifying the Company that it no longer met the minimum 1,100,000 publicly held shares required to maintain continued listing as set forth in Nasdaq’s Listing Rule 5450(b)(2)(B) (the “Public Float Standard”). Under applicable Nasdaq rules, the Company will have 45 calendar days to provide Nasdaq a plan to regain compliance with the continued listing requirements, and then, if the plan is accepted, an additional up to 180 calendar days from the date of the Public Float Notice, or until October 2, 2024, to regain compliance with the Public Float Standard. If the plan is not accepted, under Nasdaq Listing Rule 5815(a), the Company may appeal the decision to a Hearings Panel. There can be no assurance that any such appeal would be successful.

In connection with the foregoing and the previously disclosed Round Lot Notice, the Company submitted an application for a transfer from the Nasdaq Global Market to the Nasdaq Capital Market on April 8, 2024.

On April 26, 2024, the Company received written notice from the Staff stating that the Staff had approved the Company’s application to transfer the listing of its Class A ordinary shares, warrants, and units (the “Company’s Securities”) from the Nasdaq Global Market to the Nasdaq Capital Market. The Class A ordinary shares, warrants, and units will continue to trade under the symbols “ONYX,” “ONYXW,” and “ONYXU,” respectively, and trading of the Company’s Securities will be unaffected by the transfer. The Nasdaq Capital Market operates in substantially the same manner as the Nasdaq Global Market.

Risks and Uncertainties

The continuing military conflict between the Russian Federation and Ukraine, the military action between Hamas and Israel and the risk of escalations of other military conflicts have created and are expected to create global economic consequences. The specific impact on the Company’s financial condition, results of operations, and cash flows is not determinable as of the date of these unaudited condensed financial statements.

Liquidity, Capital Resources and Going Concern

As of March 31, 2024, the Company had cash of $5,744 in its operating bank account and a working capital deficit of $4,036,042.

The Company’s liquidity needs up to November 5, 2021 had been satisfied through a payment from the Sponsor of $25,000 (see Note 4) for the Founder Shares to cover certain offering costs and a loan under an unsecured promissory note from the Sponsor of $104,808, which was paid in full on November 18, 2021 (see Note 4). In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor, initial shareholders, officers, directors or their affiliates may, but are not obligated to, provide the Company Working Capital Loans, as defined below (see Note 4). As of March 31, 2024 and December 31, 2023, there were no amounts outstanding under any Working Capital Loans. In February and November 2023, the Company entered into unsecured promissory notes to the Sponsor with an aggregate borrowing capacity of $1,470,000. As of March 31, 2024 and December 31, 2023, the Company has an outstanding balance of $1,435,000 and $1,385,000 under the Restated Note, respectively.

Based on the foregoing, management believes that the Company may not have sufficient working capital to meet its needs through the earlier of the consummation of a Business Combination or one year from this filing. Over this time period, the Company will be using these funds for paying existing accounts payable, identifying and evaluating prospective initial Business Combination candidates, performing due diligence on prospective target businesses, paying for travel expenditures, selecting the target business to merge with or acquire, and structuring, negotiating and consummating the Business Combination.

The Company is within 12 months of its mandatory liquidation as of the date of filing this Quarterly Report on Form 10-Q. In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the mandatory liquidation raises substantial doubt about the Company’s ability to continue as a going concern until the earlier of the consummation of the Business Combination or November 5, 2024, the date the Company is required to liquidate.

These financial statements do not include any adjustments relating to the recovery of the recorded assets or the classification of the liabilities that might be necessary should the Company be unable to continue as a going concern.
