NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

NOTE 1. DESCRIPTION OF ORGANIZATION, BUSINESS OPERATIONS AND BASIS OF PRESENTATION

TortoiseEcofin Acquisition Corp. III (the “Company”) was incorporated as a Cayman Islands exempted company on February 3, 2021. The Company was formed for the purpose of effecting a merger, amalgamation, 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 emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

The Company has one wholly-owned subsidiary, TRTL III Merger Sub Inc., a Delaware corporation (“Merger Sub”), which was formed for the sole purpose of the consummation of a potential business combination (the “Transactions”) between the Company and One Energy Enterprises Inc., a Delaware corporation (“One Energy”) (see Note 5).

All activity for the period from February 3, 2021 (inception) through June 30, 2024 relates to the Company’s formation and its initial public offering (the “Initial Public Offering”), which is described below, and, subsequent to the Initial Public Offering, the search for a prospective acquisition for an initial Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company may generate

non-operating

income in the form of interest income on cash held in trust from the proceeds of its Initial Public Offering. The Company’s fiscal year end is December 31.

The Company’s sponsor is TortoiseEcofin Sponsor III LLC, a Cayman Islands limited liability company (the “Sponsor”), which is owned primarily by Hennessy Capital Growth Partners Fund I SPV V, LLC, a Delaware limited liability company (“HCGP”), and the Company’s management (directly or indirectly, including through family trusts). The registration statement for the Company’s Initial Public Offering was declared effective on July 19, 2021. On July 22, 2021, the Company consummated its Initial Public Offering of 30,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $28.3 million, of which $10.5 million was for deferred underwriting commissions (see Note 5) and $11.1 million was the excess of fair value over price paid for Founder Shares sold to certain qualified institutional buyers or institutional accredited investors (the “Anchor Investors”). On July 23, 2021, the underwriters exercised their over-allotment option in full and on July 27, 2021, they purchased 4,500,000 additional Units, generating gross proceeds of $45.0 million (the “Over-Allotment”), and incurring offering costs of approximately $2.5 million, of which approximately $1.6 million was for deferred underwriting commissions. Approximately $1.3 million of the offering costs were allocated to derivative warrant liabilities. The Anchor Investors purchased 32,400,000 Units in the Initial Public Offering and the Over-Allotment. None of the Anchor Investors are affiliated with any member of the Company’s management.

Simultaneously with the closing of the Initial Public Offering, the Company completed the sale of 6,333,333 warrants (each, a “Private Placement Warrant” and collectively, the “Private Placement Warrants”) in a private placement (the “Private Placement”), at a price of $1.50 per Private Placement Warrant, to TortoiseEcofin Borrower LLC, a Delaware limited liability company (“TortoiseEcofin Borrower”), generating proceeds of $9.5 million (see Note 4). Concurrently with the consummation of the Over-Allotment on July 27, 2021, TortoiseEcofin Borrower purchased 600,000 additional Private Placement Warrants, generating proceeds of $900,000 (the “Second Private Placement”). Pursuant to that certain securities purchase agreement, dated as of July 19, 2023, HCGP acquired from TortoiseEcofin Borrower all of its limited liability company interests in the Sponsor, as well as 5,893,333 Private Placement Warrants held by TortoiseEcofin Borrower.

Upon the closing of the Initial Public Offering and the Private Placement on July 22, 2021, and the Over-Allotment and the Second Private Placement on July 27, 2021, the net proceeds thereof consisting of $345.0 million ($10.00 per Unit) were placed in a trust account (the “Trust Account”), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and may be invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the “Investment Company Act”), with a maturity of 185 days or less or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule

2a-7

of the Investment Company Act, as determined by the Company, until the earlier of: (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company’s management (“management”) has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, the Over-Allotment and the sale of the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the net assets held in the Trust Account (net of amounts disbursed to management for working capital purposes and excluding the amount of any deferred underwriting discount held in the Trust Account) at the time of the signing of the agreement to enter into the initial Business Combination, and a majority of the independent directors must approve such initial Business Combination. However, the Company will only complete a Business Combination if the post-transaction 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.

TORTOISEECOFIN ACQUISITION CORP. III

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Company will provide the holders (the “Public Shareholders”) of Public Shares 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 shareholder 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. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially at $10.00 per Public Share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its taxes). 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 underwriters (as discussed in Note 5). These Public Shares are classified as temporary equity in accordance with the Financial Accounting Standards Board’s (“FASB”) Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets of at least $5,000,001 upon such consummation of a Business Combination and only if a majority of the ordinary shares, represented in person or by proxy and entitled to vote thereon, voted at a shareholder meeting are voted in favor of the Business Combination. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to the amended and restated memorandum and articles of association which the Company adopted in connection with the Initial Public Offering (the “Amended and Restated Memorandum and Articles of Association”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (the “SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transactions is required by law, or the Company decides to obtain shareholder approval for business or other reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or vote at all. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) and HCGP agreed to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering, and the Anchor Investors agreed to vote any Founder Shares held by them, in favor of a Business Combination. Subsequent to the consummation of the Initial Public Offering, the Company adopted an insider trading policy which requires insiders to: (i) refrain from purchasing shares during certain blackout periods and when they are in possession of any material

non-public

information and (ii) clear all trades with the Company’s legal counsel prior to execution. In addition, HCGP and the initial shareholders agreed that they will not be entitled to redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of its Business Combination and does not conduct redemptions in connection with its Business Combination pursuant to the tender offer rules, the Amended and Restated Memorandum and Articles of Association provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 20% of the Class A ordinary shares sold in the Initial Public Offering, without the prior consent of the Company.

At the time of the Initial Public Offering, the Company’s Sponsor, officers and directors (the “initial shareholders”) agreed not to propose an amendment to the Amended and Restated Memorandum and Articles of Association that would modify the substance or timing of the Company’s obligation to provide holders of its Public Shares the right to have their shares redeemed in connection with a Business Combination or to redeem 100% of the Company’s Public Shares if the Company does not complete its Business Combination within 24 months from the closing of the Initial Public Offering, or July 22, 2023, or 27 months from the closing of the Initial Public Offering, or October 22, 2023, if the Company executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 24 months from the closing of the Initial Public Offering but has not completed the initial Business Combination within such

24-month

period or with respect to any other provision relating to the rights of Public Shareholders, unless the Company will provide the Public Shareholders with the opportunity to redeem their Class A ordinary shares in conjunction with any such amendment. On July 20, 2023, the Company issued a press release announcing that it had executed a new

non-binding

letter of intent for a proposed business combination with an industrial renewable power solutions company (the “Letter of Intent”). As a result of the signed Letter of Intent, pursuant to the provisions of the Company’s Amended and Restated Memorandum and Articles of Association, the date by which the Company must consummate its Business Combination was automatically extended from July 22, 2023 to October 22, 2023.

On October 19, 2023, the Company held an extraordinary general meeting in lieu of an annual general meeting of shareholders (the “First Extension Meeting”) and filed an amendment to the Amended and Restated Memorandum and Articles of Association to extend the date by which the Company has to consummate an initial Business Combination from October 22, 2023 on a monthly basis up to six times until April 22, 2024 (or such earlier date as determined by the board of directors of the Company (the “Board”)). The Sponsor agreed that it or its designee would deposit $258,970.53 per month into the Trust Account, for each calendar month (commencing on October 23, 2023 and on the 23rd day of each subsequent month) until April 22, 2024, or portion thereof, that is needed to complete an initial Business Combination. As a result, the date by which the Company must consummate its Business Combination was extended from October 22, 2023 to April 22, 2024.

On April 19, 2024, the Company held an extraordinary general meeting of shareholders (the “Second Extension Meeting”) and filed an amendment to the Amended and Restated Memorandum and Articles of Association to extend the date by which the Company has to consummate an initial Business Combination from April 22, 2024 on a monthly basis (each such monthly extension, if pursued, a

“Month-to-Month

Extension”) up to six times until October 22, 2024 (or such earlier date as determined by the Board). The Sponsor agreed that it or its designee would deposit $310,396.26 per month into the Trust Account, for each calendar month (commencing on April 23, 2024 and on the 23rd day of each subsequent month) until October 22, 2024, or portion thereof, that is needed to complete an initial Business Combination. As a result, the date by which the Company must consummate its Business Combination was extended from April 22, 2024 to October 22, 2024 (the “Combination Period”).

In connection with the Second Extension Meeting, shareholders holding 1,744,889 Public Shares exercised their right to redeem such shares at a per share redemption price of approximately $10.85.

If the Company has not completed a Business Combination within 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 its taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, 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 the requirements of other applicable law.

HCGP and the initial shareholders agreed to waive their liquidation rights with respect to the Founder Shares held by them if the Company fails to complete a Business Combination within the Combination Period. However, if the initial shareholders acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete a Business Combination within the Combination Period. Three of the four underwriters agreed to waive their rights to their deferred underwriting commission (see Note 5) held in the Trust Account with respect to the Company’s Letter of Intent for the Transactions with One Energy, and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution (including Trust Account assets) will be only $10.00 per share initially held in the Trust Account. In order to protect the amounts held in the Trust Account, the Sponsor agreed to be liable to the Company if and to the extent any claims by a third party 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 amount of funds in the Trust Account to below the lesser of (i) $10.00 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 $10.00 per Public Share due to reductions in the value of the trust assets. This liability will not apply with respect to any claims by a third party who executed a waiver of any right, title, interest or claim of any kind in or to any monies held in the Trust Account or to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering 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. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (excluding the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

On July 17, 2023, three of the four underwriters for the Company’s Initial Public Offering, consisting of Barclays Capital Inc., Goldman Sachs & Co. LLC and Academy Securities, Inc., agreed to waive all rights to their respective portion of the underwriting commissions (or approximately $9.96 million of the total $12.075 million of the underwriting commissions) with respect to the Transactions with One Energy. One of the underwriters had further agreed to waive all rights to their respective portion of the underwriting commissions (approximately $4.83 million) with respect to the Transactions with One Energy or to any future Business Combination.

Pursuant to that certain securities purchase agreement, dated as of July 19, 2023, HCGP acquired from TortoiseEcofin Borrower all of its limited liability company interests in the Sponsor, as well as 5,893,333 Private Placement Warrants held by TortoiseEcofin Borrower. In connection with the transaction, HCGP assumed Tortoise Capital Advisors, L.L.C.’s (“Tortoise Capital Advisors”) rights and obligations under the Administrative Support Agreement (see Note 4).

Liquidity, Capital Resources and Going Concern

As of June 30, 2024, the Company had approximately $148,880 in operating cash and a working capital deficit of approximately $2,340,000.

The Company’s liquidity needs prior to the consummation of the Initial Public Offering were satisfied through the payment of $25,000 from the Sponsor to cover certain expenses on behalf of the Company in consideration of Founder Shares, and a loan from the Sponsor of approximately $195,000, under the Note (as defined in Note 4). The Company repaid the Note in full on July 22, 2021 and borrowings under the Note are no longer available.

Subsequent to the consummation of the Initial Public Offering, the Company’s liquidity has been satisfied through the net proceeds of $3.5 million from the consummation of the Initial Public Offering, the Over-Allotment, the Private Placement and the Second Private Placement held outside of the Trust Account. In addition, in order to finance general working capital needs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, provide the Company Working Capital Loans (as defined in Note

). On February 1, 2023, the Company issued a nonconvertible, unsecured promissory note (the “February 2023 Note”) in the principal amount of $500,000 to TortoiseEcofin Borrower. The February 2023 Note is not convertible into equity securities, does not bear interest and is repayable in full upon consummation of a Business Combination. If the Company does not complete a Business Combination, the February 2023 Note will not be repaid and all amounts owed under it will be forgiven. On February 1, 2023, March 9, 2023 and May 9, 2023, the Company borrowed $100,000, $50,000 and $185,000, respectively, under the February 2023 Note. As of June 30, 2024 and December 31, 2023, the Company had $335,000 outstanding under Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans have not been determined and no written agreements exist with respect to such loans.

On July 19, 2023, the Company issued a promissory note (the “July 2023 Note”) in the principal amount of up to $1,000,000 to HCGP. The July 2023 Note was issued in connection with advances HCGP may make in the future to the Company for working capital expenses. The July 2023 Note bears no interest and is repayable in full upon the earlier of (i) the date on which the Company consummates its initial Business Combination and (ii) the date that the winding up of the Company is effective. At the election of HCGP, all or a portion of the unpaid principal amount of the July 2023 Note may be converted into warrants that are identical to the Private Placement Warrants (the “Conversion Warrants”) at a price of $1.50 per warrant. The Conversion Warrants and their underlying securities are entitled to the registration rights set forth in the July 2023 Note. On August 7, 2023 and August 18, 2023, the Company borrowed $100,000 and $280,000, respectively, under the July 2023 Note. As of June 30, 2024, the Company had $380,000 outstanding under the July 2023 Note which is recorded as convertible note – related party on the accompanying condensed consolidated balance sheets. See Note 4.

In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC Topic

205-40,

“Presentation of Financial Statements-Going Concern,” management has determined that the liquidity condition and mandatory liquidation and subsequent dissolution raise substantial doubt about the Company’s ability to continue as a going concern. The Company intends to complete a Business Combination before the mandatory liquidation date of October 22, 2024; however, there can be no assurance that the Company will be able to consummate a Business Combination by the Combination Period. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The condensed consolidated financial statements do not include any adjustment that might be necessary if the Company is unable to continue as a going concern.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited condensed consolidated financial statements are presented in U.S. dollars in conformity with accounting principles generally accepted in the United States of America (“GAAP”) for financial information and pursuant to the rules and regulations of the SEC. Accordingly, they do not include all of the information and footnotes required by GAAP. In the opinion of management, all adjustments (consisting of normal accruals) considered for a fair presentation have been included. Operating results for the three and six months ended June 30, 2024 are not necessarily indicative of the results that may be expected for the year ending December 31, 2024 or any future period.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the audited financial statements and notes thereto included in the Annual Report on Form

10-K

filed by the Company with the SEC on April 1, 2024.

Principles of Consolidation

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly-owned subsidiary, Merger Sub. There has been no intercompany activity since inception.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Table of Contents

TORTOISEECOFIN ACQUISITION CORP. III

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth company can elect to opt out of the extended transition period and comply with the requirements that apply to

non-emerging

growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company’s condensed consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company which has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

Use of Estimates

The preparation of condensed consolidated financial statements in conformity with GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements and the reported amounts of revenues and expenses during the reporting periods.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the condensed consolidated financial statements, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $250,000. Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. There were no cash equivalents as of June 30, 2024 and December 31, 2023.

Cash Held in Trust Account

On June 14, 2023, the Company liquidated the U.S. government treasury obligations or money market funds held in the Trust Account. The funds in the Trust Account are currently maintained in cash in an interest-bearing demand deposit account at a bank until the earlier of consummation of the Company’s initial Business Combination and liquidation. Prior to June 14, 2023, the Company’s portfolio of investments was comprised of U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less, or investments in money market funds that invest in U.S. government securities and generally have a readily determinable fair value, or a combination thereof. When the Company’s investments held in the Trust Account are comprised of U.S. government securities, the investments are classified as trading securities. When the Company’s investments held in the Trust Account are comprised of money market funds, the investments are recognized at fair value. Trading securities and investments in money market funds are presented on the condensed consolidated balance sheets at fair value at the end of each reporting period. Gains and losses resulting from the change in fair value of these securities is included in income from investments held in the Trust Account in the accompanying condensed consolidated statements of operations. As of December 31, 2023 the estimated fair values of investments held in the Trust Account are determined using available market information. As of June 30, 2024 and December 31, 2023, approximately $170.2 million and $183.3 million was held in the Trust Account, respectively.

Fair Value of Financial Instruments

The carrying value of the Company’s assets and liabilities recognized in the condensed consolidated balance sheets, which qualify as financial instruments under the FASB ASC Topic 820, “Fair Value Measurements,” equals or approximates the fair values for such assets and liabilities either because of the short-term nature of the instruments or because the instrument is recognized at fair value.

Table of Contents

TORTOISEECOFIN ACQUISITION CORP. III

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Fair Value Measurements

Fair value is defined as the price that would be received for sale of an asset or paid for transfer of a liability, in an orderly transaction between market participants at the measurement date. GAAP establishes a three-tier fair value hierarchy, which prioritizes the inputs used in measuring fair value. The hierarchy gives the highest priority to unadjusted quoted prices in active markets for identical assets or liabilities (Level 1 measurements) and the lowest priority to unobservable inputs (Level 3 measurements). These tiers consist of:

•

Level 1, defined as observable inputs such as quoted prices (unadjusted) for identical instruments in active markets;

•

Level 2, defined as inputs other than quoted prices included in Level 1 that are observable for the asset or liability, either directly or indirectly; and

•

Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable.

In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Derivative Warrant Liabilities

The Company does not use derivative instruments to hedge exposures to cash flow, market, or foreign currency risks. The Company evaluates all of its financial instruments, including issued warrants to purchase shares, to determine if such instruments are derivatives or contain features that qualify as embedded derivatives, pursuant to ASC 480 and FASB ASC Topic 815, “Derivatives and Hedging” (“ASC 815”). The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is

re-assessed

at the end of each reporting period.

The warrants issued in connection with the Initial Public Offering and the Over-Allotment (the “Public Warrants”) and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjusts the instruments to fair value at each reporting period. The liabilities are subject to

re-measurement

at each balance sheet date until exercised, and any change in fair value will be recognized in the Company’s statements of operations. The fair value of the Public Warrants and the Private Placement Warrants were initially measured at fair value using a Black-Scholes Option Pricing Method and Monte Carlo simulation, respectively. Subsequent to the Public Warrants being separately listed and traded from the Units, the fair value of the Public Warrants was measured based on their listed market price, and the fair value of the Private Placement Warrants was estimated by reference to the listed market price of the Public Warrants. The determination of the fair value of the warrant liabilities may be subject to change as more current information becomes available and accordingly the actual results could differ significantly. Derivative warrant liabilities are classified as

non-current

liabilities as their liquidation will not be reasonably expected to require the use of current assets or require the creation of current liabilities.

Offering Costs Associated with Initial Public Offering

Offering costs consists of legal, accounting, underwriting fees and other costs incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs are allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to the total proceeds received. Offering costs associated with derivative warrant liabilities are expensed as incurred, presented as

non-operating

other income in the condensed consolidated statements of operations. Offering costs associated with the Class A ordinary shares issued were charged against their carrying value upon the completion of the Initial Public Offering. The Company classifies deferred underwriting commissions as

non-current

liabilities as their liquidation is not reasonably expected to require the use of current assets or require the creation of current liabilities.

Class A Ordinary Shares Subject to Possible Redemption

As discussed in Note 1, all of the Class A ordinary shares sold as part of the Units in the Initial Public Offering and the Over-Allotment contain a redemption feature which allows for the redemption of the Public Shares in connection with the Company’s liquidation, if there is a shareholder vote or tender offer in connection with the Business Combination and in connection with certain amendments to the Company’s Amended and Restated Memorandum and Articles of Association. In accordance with ASC 480, conditionally redeemable Class A ordinary shares (including Class A ordinary shares that feature redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company’s control) are classified as temporary equity. Ordinary liquidation events, which involve the redemption and liquidation of all of the entity’s equity instruments, are excluded from the provisions of ASC 480.

TORTOISEECOFIN ACQUISITION CORP. III

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

At the First Extension Meeting, shareholders holding 17,235,298 of the Company’s Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $180.9 million (approximately $10.49 per share) was removed from the Trust Account to pay such holders. In connection with the Second Extension Meeting, shareholders holding 1,744,889 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $18.9 million (approximately $10.85 per share) was removed from the Trust Account to pay such holders. As of June 30, 2024 and December 31, 2023, 15,519,813 and 17,264,702 Class A ordinary shares subject to possible redemption at the redemption amount are presented as temporary equity, respectively, outside of the shareholders’ deficit section of the Company’s condensed consolidated balance sheets.

Under ASC

480-10-S99,

the Company has elected to recognize changes in the redemption value immediately as they occur and adjust the carrying value of the security to equal the redemption value at the end of the reporting period. This method would view the end of the reporting period as if it were also the redemption date of the security. Effective with the closing of the Initial Public Offering and the Over-Allotment, the Company recognized the accretion from initial book value to redemption amount, which resulted in charges against additional

paid-in

capital (to the extent available) and accumulated deficit. Subsequently, the Company recognized changes in the redemption value as an increase in the redemption value of the Class A ordinary share subject to possible redemption as reflected on the accompanying condensed consolidated statements of changes in shareholders’ deficit.

Income Taxes

FASB ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be

more-likely-than-not

to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s only major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits and no amounts accrued for interest and penalties as of June 30, 2024 and December 31, 2023. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

There is currently no taxation imposed on income by the government of the Cayman Islands. In accordance with Cayman Islands’ federal income tax regulations, income taxes are not levied on the Company. Consequently, income taxes are not reflected in the Company’s condensed consolidated financial statements. The Company’s management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

Net Income Per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share.” The Company has two classes of shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of shares. Net income per ordinary share is calculated by dividing the net income by the weighted average of ordinary shares outstanding for the respective period.

The calculation of diluted net income does not consider the effect of the Public Warrants and the Private Placement Warrants to purchase an aggregate of 15,558,333 Class A ordinary shares in the calculation of diluted income per share, because their exercise is contingent upon future events. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

The following table presents a reconciliation of the numerator and denominator used to compute basic and diluted net income per share for each class of ordinary shares:

Recent Accounting Pronouncements

Management does not believe that any recently issued, but not yet effective, accounting pronouncements, if currently adopted, would have a material effect on the Company’s condensed consolidated financial statements.

NOTE 3. INITIAL PUBLIC OFFERING

On July 22, 2021, the Company consummated its Initial Public Offering of 30,000,000 Units, at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $28.3 million, of which $10.5 million was for deferred underwriting commissions and $11.1 million was the excess of fair value over price paid of Founder Shares sold to the Anchor Investors. On July 23, 2021, the underwriters exercised their over-allotment option in full and on July 27, 2021, they purchased 4,500,000 additional Units, generating gross proceeds of $45.0 million, and incurring offering costs of approximately $2.5 million, of which approximately $1.6 million was for deferred underwriting commissions. Approximately $1.3 million of the offering costs were allocated to derivative warrant liabilities. The Anchor Investors purchased 32,400,000 Units in the Initial Public Offering and the Over-Allotment. None of the Anchor Investors is affiliated with any member of the Company’s management.

Each Unit consists of one Class A ordinary share and

one-fourth

of one Public Warrant. Each whole Public Warrant entitles the holder to purchase one Class A ordinary share at an exercise price of $11.50 per share, subject to adjustment (see Note 8).

NOTE 4. RELATED PARTY TRANSACTIONS

Founder Shares

On February 9, 2021, the Sponsor paid $25,000, or approximately $0.003 per share, to cover certain expenses on behalf of the Company in consideration of 7,187,500 Class B ordinary shares, par value $0.0001 per share (the “Founder Shares”). On February 18, 2021, the Company issued 1,437,500 Class B ordinary shares in connection with a share capitalization, resulting in an aggregate of 8,625,000 Founder Shares outstanding. The Sponsor agreed to forfeit up to 1,125,000 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters, so that the Founder Shares would represent 20.0% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering. On July 27, 2021, the underwriters purchased the Units subject to the over-allotment option in full, and as a result, 1,125,000 Founder Shares were no longer subject to possible forfeiture.

In exchange for the Anchor Investors’ participation in the Initial Public Offering as described in Note 3, the Sponsor sold a total of 1,650,000 Founder Shares to the Anchor Investors. The Company determined that the fair value of these Founder Shares was approximately $11.1 million (or $6.73 per share) using a Monte Carlo simulation. The Company recognized the excess fair value of these Founder Shares, over the price paid by the Anchor Investors, as a cost of the Initial Public Offering.

The holders of the Founder Shares, including the Anchor Investors, agreed, subject to limited exceptions, not to transfer, assign or sell any of their Founder Shares until one year after the completion of a Business Combination or earlier if, subsequent to the Business Combination, (x) the last sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share

sub-divisions,

share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any

30-trading

day period commencing at least 120 days after the Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the shareholders having the right to exchange their ordinary shares for cash, securities or other property.

Private Placement Warrants

Simultaneously with the closing of the Initial Public Offering, the Company completed the sale of 6,333,333 Private Placement Warrants in a Private Placement, at a price of $1.50 per Private Placement Warrant, to TortoiseEcofin Borrower, generating proceeds of $9.5 million. Concurrently with the consummation of the Over-Allotment on July 27, 2021, TortoiseEcofin Borrower purchased 600,000 additional Private Placement Warrants, generating proceeds of $900,000. Pursuant to that certain securities purchase agreement, dated as of July 19, 2023, HCGP acquired from TortoiseEcofin Borrower all of its limited liability company interests in the Sponsor, as well as 5,893,333 Private Placement Warrants held by TortoiseEcofin Borrower.

Each whole Private Placement Warrant is exercisable for one whole Class A ordinary share at a price of $11.50 per share. A portion of the proceeds from the sale of the Private Placement Warrants was added to the proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete a Business Combination within the Combination Period, the proceeds from the sale of the Private Placement Warrants held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law) and the Private Placement Warrants will expire worthless. The Private Placement Warrants will be

non-redeemable

for cash and exercisable on a cashless basis so long as they are held by TortoiseEcofin Borrower or its permitted transferees.

HCGP, TortoiseEcofin Borrower, the Sponsor and the Company’s officers and directors agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Warrants until 30 days after the completion of a Business Combination (see Note 8).

Related Party Loans

On February 3, 2021, the Sponsor agreed to loan the Company an aggregate of up to $600,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan was

non-interest

bearing and payable upon the consummation of the Initial Public Offering. The Company borrowed approximately $195,000 under the Note and repaid the Note in full on July 22, 2021 and borrowings thereunder are no longer available.

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (“Working Capital Loans”). If the Company completes a Business Combination, the Company may repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans may be repaid only out of funds held outside the Trust Account. In the event that a Business Combination is not completed within the Combination Period, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into warrants of the post Business Combination entity at a price of $1.50 per warrant. The warrants would be identical to the Private Placement Warrants.

On February 1, 2023, the Company issued the February 2023 Note in the principal amount of $500,000 to TortoiseEcofin Borrower. The February 2023 Note is not convertible into equity securities, does not bear interest and is repayable in full upon consummation of a Business Combination. If the Company does not complete a Business Combination, the February 2023 Note will not be repaid and all amounts owed under it will be forgiven.

On February 1, 2023, March 9, 2023 and May 9, 2023, the Company borrowed $100,000, $50,000 and $185,000, respectively, under the February 2023 Note. As of June 30, 2024 and December 31, 2023, the Company had $335,000 outstanding under Working Capital Loans. Except for the foregoing, the terms of such Working Capital Loans have not been determined and no written agreements exist with respect to such loans.

On July 19, 2023, the Company issued the July 2023 Note in the principal amount of up to $1,000,000 to HCGP. The July 2023 Note was issued in connection with advances HCGP may make in the future to the Company for working capital expenses. The July 2023 Note bears no interest and is repayable in full upon the earlier of (i) the date on which the Company consummates its initial Business Combination and (ii) the date that the winding up of the Company is effective. At the election of HCGP, all or a portion of the unpaid principal amount of the July 2023 Note may be converted into Conversion Warrants at a price of $1.50 per warrant. The Conversion Warrants and their underlying securities are entitled to the registration rights set forth in the July 2023 Note. On August 7, 2023 and August 18, 2023, the Company borrowed $100,000 and $280,000, respectively, under the July 2023 Note. As of June 30, 2024 and December 31, 2023, the Company had $380,000 outstanding under the July 2023 Note which is recorded as convertible note – related party on the accompanying condensed consolidated balance sheets.

Administrative Support Agreement

On July 19, 2021, the Company entered into an administrative support agreement (the “Administrative Support Agreement”) with Tortoise Capital Advisors, pursuant to which, commencing on the date that the Company’s securities were first listed on the New York Stock Exchange through the earlier of consummation of a Business Combination and the date of the Company’s liquidation, the Company agreed to pay Tortoise Capital Advisors $10,000 per month for office space, utilities and secretarial and administrative support made available to the Company. For the three and six months ended June 30, 2024, the Company incurred $30,000 and $60,000, respectively, for such expenses, included as general and administrative expenses—related party on the accompanying unaudited condensed financial statements of operations.

The Company’s audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, the Company’s executive officers or directors, or the Company’s or their affiliates. Any such payments prior to a Business Combination will be made using funds held outside the Trust Account.

NOTE 5. COMMITMENTS AND CONTINGENCIES

Registration Rights

The holders of the Founder Shares, Private Placement Warrants and warrants that may be issued upon conversion of Working Capital Loans (and any Class A ordinary shares issuable upon the exercise of the Private Placement Warrants and warrants that may be issued upon conversion of the Working Capital Loans and upon conversion of the Founder Shares), and any Class A ordinary shares held by the Company’s initial shareholders and HCGP at the completion of the Initial Public Offering or acquired prior to or in connection with a Business Combination, are entitled to registration rights pursuant to a registration rights agreement entered into on the effective date of the Initial Public Offering. The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company registers such securities. In addition, the holders have certain “piggyback” registration rights with respect to registration statements filed subsequent to the Company’s completion of its Business Combination. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable

lock-up

period, which occurs (i) in the case of the Founder Shares held by the initial shareholders, in accordance with the letter agreement the Company’s initial shareholders entered into, (ii) in the case of the Founder Shares held by the Anchor Investors, in accordance with the investment agreements entered into by and among the Company, the Sponsor and the Anchor Investors and (iii) in the case of the Private Placement Warrants, 30 days after the completion of the Company’s Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriters a

45-day

option from the date of the final prospectus relating to the Initial Public Offering to purchase up to 4,500,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions. The underwriters purchased the Units subject to the over-allotment option in full on July 27, 2021.

The underwriters were entitled to underwriting commissions of $0.20 per Unit, or $6.0 million in the aggregate, paid upon the closing of the Initial Public Offering. In addition, $0.35 per Unit, or $10.5 million in the aggregate, will be payable to the underwriters for deferred underwriting commissions. The deferred commissions will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

In connection with the consummation of the Over-Allotment on July 27, 2021, the underwriters were paid an additional fee of $900,000, and approximately $1.6 million in additional deferred underwriting commissions will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

Deferred Legal Fees Associated with the Initial Public Offering and Certain Other Matters

The Company entered into an engagement letter to obtain legal advisory services, pursuant to which the Company’s legal counsel agreed to defer half of their fees associated with the Initial Public Offering until the closing of a Business Combination and has agreed to the deferral of certain other legal expenses in connection with the Business Combination. As of June 30, 2024 and December 31, 2023, the Company recorded an aggregate of approximately $174,000 for such deferred legal fees in the accompanying condensed consolidated balance sheets.

Risks and Uncertainties

Various social and political circumstances in the United States and around the world (including wars and other forms of conflict, including rising trade tensions between the United States and China, and other uncertainties regarding actual and potential shifts in the United States and foreign, trade, economic and other policies with other countries, terrorist acts, security operations and catastrophic events such as fires, floods, earthquakes, tornadoes, hurricanes and global health epidemics), may also contribute to increased market volatility and economic uncertainties or deterioration in the United States and worldwide. Specifically, the military conflicts in Ukraine and in the Middle East, and resulting market volatility, could adversely affect the Company’s ability to complete a Business Combination. In response to the conflicts between Russia and Ukraine, the United States and other countries have imposed sanctions or other restrictive actions against Russia. Any of the above factors, including sanctions, export controls, tariffs, trade wars and other governmental actions, could have a material adverse effect on the Company’s ability to complete a Business Combination and the value of the Company’s securities.

As a result, the date by which the Company must consummate its Business Combination was extended from April 22, 2024 to October 22, 2024. In connection with the Second Extension Meeting, shareholders holding 1,744,889 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $18.9 million (approximately $10.85 per share) was removed from the Trust Account to pay such holders.

In connection with the Second Extension Meeting, to extend the date by which the Company must consummate an initial Business Combination from April 22, 2024, on a monthly basis, up to six times until October 22, 2024 (or such earlier date as determined by the Board), the Company entered into several agreements as further described herein.

The Company is authorized to issue 220,000,000 ordinary shares with a par value of $0.0001 per share. Holders of the Company’s Class A ordinary shares are entitled to one vote for each share. In connection with the First Extension Meeting, shareholders holding 17,235,298 of the Company’s Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $180.9 million (approximately $10.49 per share) was removed from the Trust Account to pay such holders. As of June 30, 2024 and December 31, 2023, there were

15,519,813

and

17,264,702

Class A ordinary shares outstanding, respectively, all of which were subject to possible redemption. In connection with the Second Extension Meeting, shareholders holding 1,744,889 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. As a result, approximately $18.9 million (approximately $10.85 per share) was removed from the Trust Account to pay such holders.

NOTE 7. SHAREHOLDERS’ DEFICIT

Preference Shares

- The Company is authorized to issue 1,000,000 preference shares with such designations, voting and other rights and preferences as may be determined from time to time by the Board. As of June 30, 2024 and December 31, 2023, there were no preference shares issued or outstanding.

Class

A Ordinary Shares

- The Company is authorized to issue 200,000,000 Class A ordinary shares with a par value of $0.0001 per share. As of June 30, 2024 and December 31, 2023, there were 15,519,813 and 17,264,702 Class A ordinary shares issued and outstanding, subject to possible redemption, respectively, and therefore classified as temporary equity (see Note 6). In connection with the First Extension Meeting, shareholders holding 17,235,298 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account. In connection with the Second Extension Meeting, shareholders holding 1,744,889 Public Shares exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account.

Class

B Ordinary Shares

- The Company is authorized to issue 20,000,000 Class B ordinary shares with a par value of $0.0001 per share. In February 2021, the Company issued 7,187,500 Class B ordinary shares to the Sponsor in exchange for the payment of $25,000, or approximately $0.003 per share. On February 18, 2021, the Company issued 1,437,500 Class B ordinary shares to the Sponsor in connection with a share capitalization, resulting in the Sponsor holding an aggregate of 8,625,000 Founder Shares. All shares and associated amounts have been retroactively adjusted to reflect the share capitalization. Of the 8,625,000 Class B ordinary shares, an aggregate of up to 1,125,000 shares were subject to forfeiture to the Company by the Sponsor for no consideration to the extent that the underwriters’ over-allotment option was not exercised in full or in part, so that holders of the Founder Shares would collectively own 20% of the Company’s issued and outstanding ordinary shares. The underwriters purchased the units subject to the over-allotment option in full on July 27, 2021; therefore, these 1,125,000 Class B ordinary shares were no longer subject to possible forfeiture. As a result, as of June 30, 2024 and December 31, 2023, there were 8,625,000 Class B ordinary shares outstanding and none subject to forfeiture.

Table of Contents

TORTOISEECOFIN ACQUISITION CORP. III

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Holders of the Class A ordinary shares and holders of the Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the shareholders, except that in respect of any vote or votes to continue the Company in a jurisdiction outside the Cayman Islands (including, but not limited to, the approval of the organizational documents of the Company in such other jurisdiction), holders of Class B ordinary shares will have ten votes per share and holders of Class A ordinary shares will have one vote per share, and except as required by law or stock exchange rule; provided that only holders of the Class B ordinary shares have the right to vote on the election of the Company’s directors (and may also remove a member of the Board for any reason) prior to a Business Combination.

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the initial Business Combination on a

one-for-one

basis, subject to adjustment for share

sub-divisions,

share dividends, reorganizations, recapitalizations and the like and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts sold in the Initial Public Offering and related to the closing of a Business Combination, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the holders of a majority of the outstanding Class B ordinary shares agree to waive such adjustment with respect to any such issuance or deemed issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an

as-converted

basis, 20% of the sum of the total number of all ordinary shares outstanding upon the completion of the Initial Public Offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the Business Combination (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the Business Combination). In no event will the Class B ordinary shares convert into Class A ordinary shares at a rate of less than

one-to-one.

NOTE 8. DERIVATIVE WARRANT LIABILITIES

As of June 30, 2024 and December 31, 2023, 8,625,000 Public Warrants and 6,933,333 Private Placement Warrants were outstanding.

The Public Warrants may only be exercised for a whole number of shares. No fractional Public Warrants will be issued upon separation of the Units and only whole Public Warrants will trade. The Public Warrants will become exercisable 30 days after the completion of a Business Combination; provided that the Company has an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the Public Warrants and a current prospectus relating to them is available and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder (or the Company permit holders to exercise their warrants on a cashless basis under certain circumstances). The Company registered the Class A ordinary shares issuable upon exercise of the warrants and agreed to use commercially reasonable efforts to maintain a current prospectus relating to those Class A ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement. If the Class A ordinary shares are at the time of any exercise of a warrant not listed on a national securities exchange such that they satisfy the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their warrants to do so on a “cashless basis” and, in the event the Company so elects, the Company will not be required to file or maintain in effect a registration statement, and in the event the Company does not so elect, it will use commercially reasonable efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

The warrants have an exercise price of $11.50 per share, subject to adjustments, and will expire five years after the completion of a Business Combination or earlier upon redemption or liquidation. In addition, if the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of a Business Combination at an issue price or effective issue price of less than $9.20 per share of Class A ordinary shares (with such issue price or effective issue price to be determined in good faith by the board and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the Newly Issued Price.

The Private Placement Warrants are identical to the Public Warrants underlying the Units sold in the Initial Public Offering, except that the Private Placement Warrants and the Class A ordinary shares issuable upon exercise of the Private Placement Warrants will not be transferable, assignable or salable until 30 days after the completion of a Business Combination, subject to certain limited exceptions. Additionally, the Private Placement Warrants will be

non-redeemable

so long as they are held by the initial purchasers or such purchasers’ permitted transferees. If the Private Placement Warrants are held by someone other than the initial shareholders or their permitted transferees, the Private Placement Warrants will be redeemable by the Company and exercisable by such holders on the same basis as the Public Warrants.

Once the warrants become exercisable, the Company may redeem the outstanding warrants for cash (except as described herein with respect to the Private Placement Warrants):

•

in whole and not in part;

•

at a price of $0.01 per warrant;

•

upon a minimum of 30 days’ prior written notice of redemption; and

•

if, and only if, the last sale price of Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share

sub-divisions,

share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a

30-trading day

period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

Table of Contents

TORTOISEECOFIN ACQUISITION CORP. III

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

The Company will not redeem the warrants for cash unless a registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the warrants is effective and a current prospectus relating to those Class A ordinary shares is available throughout

the 30-day redemption

period, except if the warrants may be exercised on a cashless basis and such cashless exercise is exempt from registration under the Securities Act.

Commencing 90 days after the warrants become exercisable, the Company may redeem the outstanding warrants for Class A ordinary shares:

•

in whole and not in part;

•

at a price equal to a number of Class A ordinary shares to be determined by reference to an agreed table based on the redemption date and the “fair market value” of Class A ordinary shares;

•

upon a minimum of 30 days’ prior written notice of redemption; and

•

if, and only if, the last sale price of Class A ordinary shares equals or exceeds $10.00 per share (as adjusted per share

sub-divisions,

share dividends, reorganizations, recapitalizations and the like) on the trading day prior to the date on which the Company sends the notice of redemption to the warrant holders.

The “fair market value” of Class A ordinary shares shall mean the average reported last sale price of Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

In no event will the Company be required to net cash settle any warrant. If the Company is unable to complete a Business Combination within the Combination Period and the Company liquidates the funds held in the Trust Account, holders of warrants will not receive any of such funds with respect to their warrants, nor will they receive any distribution from the Company’s assets held outside of the Trust Account with the respect to such warrants. Accordingly, the warrants may expire worthless.

NOTE 9. FAIR VALUE MEASUREMENTS

The following tables present information about the Company’s assets and liabilities as of June 30, 2024 and December 31, 2023, that are measured at fair value on a recurring basis, by level within the fair value hierarchy:

NOTES TO UNAUDITED CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

Transfers to/from Levels 1, 2 and 3 are recognized at the beginning of the reporting period. The estimated fair value of Public Warrants was transferred from a Level 2 measurement to a Level 1 measurement due to volume activity as of June 30, 2024. There were no transfers recognized during the three and six months ended June 30, 2023.

The Public Warrants issued in connection with the Initial Public Offering and the Over-Allotment, and the Private Placement Warrants sold in the Private Placement and the Second Private Placement were initially measured at fair value using a Black-Scholes option pricing model and a Monte Carlo simulation, respectively. For periods subsequent to the detachment of the Public Warrants from the Units, the fair value of the Public Warrants is based on the observable listed price for such warrants, and the fair value of the warrants issued in the Private Placement and the Second Private Placement was estimated by reference to the listed market price of the Public Warrants.

For the three and six months ended June 30, 2024, the Company recognized a loss resulting from an increase in the fair value of the derivative warrant liabilities of approximately $832,000 and $1.1 million, respectively, presented as change in the fair value of derivative warrant liabilities in the accompanying condensed consolidated statements of operations. For the three and six months ended June 30, 2023, the Company recognized a gain resulting from a decrease in fair value of the derivative warrant liabilities of approximately $839,000 and $2.4 million, respectively, presented as change in fair value of derivative warrant liabilities in the accompanying unaudited condensed statements of operations.

NOTE 10. SUBSEQUENT EVENTS

The Company evaluated subsequent events and transactions that occurred up to the date the unaudited condensed consolidated financial statements were issued. Based on this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited condensed consolidated financial statements, other than as described below.

On July 22, 2024, the Company received a letter from the New York Stock Exchange (“NYSE”) stating that the staff of NYSE Regulation has determined to commence proceedings to delist the Company’s units, Class A ordinary shares and warrants (collectively, the “Securities”) pursuant to Sections 802.01B and 102.06e. of the NYSE’s Listed Company Manual because the Company failed to consummate a Business Combination within the shorter of (i) three years or (ii) the time period specified in the Company’s constitutive documents or by contract. Trading in the Securities on NYSE was suspended after market close on July 22, 2024. The Securities have been quoted on the OTC markets since July 23, 2024, under the ticker symbols “TRTUF” for units, “TRTLF” for Class A ordinary shares and “TRTWF” for warrants. On August 8, 2024, NYSE filed a notification of removal from listing and/or registration on Form 25 with the SEC. The Company will remain a reporting entity under the Exchange Act, ensuring continued disclosure of financial and operational information.

On July 25, 2024, the Company received a letter from One Energy purporting to unilaterally terminate the Business Combination Agreement. The Company has responded to One Energy’s letter disputing One Energy’s ability to terminate the contemplated Transactions under the terms of the Business Combination Agreement, which, in the Company’s view, remains in effect. The Company is exploring all of its legal options.

Overview

We are a blank check company incorporated as a Cayman Islands exempted company on February 3, 2021. We were incorporated for the purpose of effecting an initial Business Combination with one or more businesses or entities that we have not yet identified.

Our Sponsor is TortoiseEcofin Sponsor III LLC, a Cayman Islands limited liability company, which is owned primarily by HCGP, and its consolidated subsidiaries and our management (directly or indirectly, including through family trusts). On February 9, 2021, the Sponsor paid $25,000, or approximately $0.003 per share, to cover certain expenses on behalf of the Company in consideration of 7,187,500 Founder Shares. The registration statement for our Initial Public Offering was declared effective by the SEC on July 19, 2021. On July 22, 2021, we consummated our Initial Public Offering of 30,000,000 Units, at $10.00 per Unit, generating gross proceeds of $300.0 million, and incurring offering costs of approximately $28.3 million, of which $10.5 million was for deferred underwriting commissions and $11.1 million was the excess of the fair value of the Founder Shares sold by the Sponsor to the Anchor Investors over the price paid by such Anchor Investors for such Founder Shares. On July 23, 2021, the underwriters exercised their over-allotment option in full and on July 27, 2021, they purchased 4,500,000 additional Units, generating gross proceeds of $45.0 million, and incurring offering costs of approximately $2.5 million, of which approximately $1.6 million was for deferred underwriting commissions. Approximately $1,329,000 of the offering costs were allocated to derivative warrant liabilities.

Simultaneously with the closing of our Initial Public Offering, we completed the sale of 6,333,333 Private Placement Warrants in a private placement (the “Private Placement”), at a price of $1.50 per Private Placement Warrant, to TortoiseEcofin Borrower, generating proceeds of $9.5 million. Concurrently with the consummation of the Over-Allotment on July 27, 2021, TortoiseEcofin Borrower purchased 600,000 additional Private Placement Warrants, generating proceeds of $900,000 (the “Second Private Placement”). Pursuant to that certain securities purchase agreement, dated as of July 19, 2023, HCGP acquired from TortoiseEcofin Borrower all of its limited liability company interests in the Sponsor, as well as 5,893,333 Private Placement Warrants held by TortoiseEcofin Borrower.

Upon the closing of the Initial Public Offering and the Private Placement on July 22, 2021, and the closing of the Over-Allotment and the Second Private Placement on July 27, 2021, the net proceeds thereof consisting of $345.0 million ($10.00 per Unit) were placed in the Trust Account, located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and may be invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, with a maturity of 185 days or less or in money market funds meeting the conditions of paragraphs (d)(1), (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, as determined by us, until the earlier of: (i) the completion of an initial Business Combination and (ii) the distribution of the Trust Account as described below.

Our management has broad discretion with respect to the specific application of the net proceeds of our Initial Public Offering, the Over-Allotment and the sale of Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward consummating an initial Business Combination. If we have not completed an initial Business Combination by October 22, 2024, or a later date if extended, 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 its taxes (less up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding public shares, which redemption will completely extinguish our public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject in the case of clauses (ii) and (iii), to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

On February 14, 2024, we entered into an Amended and Restated Business Combination Agreement with One Energy, Pubco and the Merger Subs. It is proposed that, at the closing of the Transactions with One Energy, Pubco will change its name to “One Power Company.”

On May 13, 2024, the Company, One Energy, Pubco and the Merger Subs entered into Amendment No. 1, which reflects the following changes and adjustments relative to the terms set forth in the Business Combination Agreement: (i) a reduction in the number of Sponsor Earnout Shares that will, for a period after the Closing, be subject to certain contingent forfeiture terms from 1,750,000 Pubco Common Shares to 500,000 Pubco Common Shares, (ii) the receipt of additional loans contributed to the Company by the Sponsor and (iii) the removal from the Business Combination Agreement of the condition to the Closing that the Company, at the Closing, have at least $5,000,001 of net tangible assets.

Contemporaneously with the execution of Amendment No. 1, the Sponsor entered into the Amended and Restated Sponsor Letter Agreement with Pubco, the Company, One Energy and certain Class B Holders, which amends, restates and replaces the Original Sponsor Letter Agreement. Pursuant to the Amended and Restated Sponsor Letter Agreement, (i) Pubco, which was not a party to the Original Sponsor Letter Agreement, became a party to the agreement and (ii) references to the Company’s Class A ordinary shares were replaced with references to Pubco Common Shares. Additionally, the Class B Holders agreed, together with the Company and Pubco, solely for the limited purposes of applicable provisions, that, effective as of the Closing Date, the original lock-up terms applicable to the Sponsor and each other relevant party under the terms of the letter agreement dated July 19, 2021, between the Company, the Sponsor and the other parties thereto entered into at the time of the Initial Public Offering would be extended to the Revised Lock-Up Terms. The “Revised Lock-Up Terms” are the provisions in the Amended and Restated Sponsor Letter Agreement which reflect that, subject to certain exceptions, the Sponsor and each Class B Holder have agreed not to transfer any of the 7,187,500 Class B ordinary shares purchased by the Sponsor in February 2021 until, in the context of the proposed Transactions, the earlier of (i) two years after the Closing Date, (ii) the first date after the Closing Date when the volume-weighted average share price of Pubco Common Shares as displayed on Pubco’s page on Bloomberg (or any successor service) in respect of the period from 9:30 a.m. to 4:00 p.m., New York City time, on the applicable trading day equals or exceeds $15.00 per share (as adjusted for share splits, reorganizations, recapitalizations and the like) for any 20 trading days within a 30-day trading period commencing at least 120 days after the Closing and (iii) the date after the Closing Date when Pubco consummates a liquidation, merger, share exchange or other similar transaction resulting in Pubco shareholders having the right to exchange shares of Pubco for other property.

Contemporaneously with the execution of Amendment No. 1, on May 13, 2024, the Supporting Company Stockholders entered into the Amended and Restated Stockholder Support Agreement, which supersedes the Original Transaction Support Agreement to add Pubco as a party to such agreement.

On December 10, 2023, the Company entered into the December 2023 Loan and Transfer Agreements with the Sponsor, One Energy and the December 2023 Lenders, pursuant to which the December 2023 Lenders agreed to loan an aggregate of $1.0 million to the Sponsor and the Sponsor loaned such amount to the Company. Neither the December 2023 Loan nor the December 2023 SPAC Loan will accrue any interest. As of June 30, 2024 and December 31, 2023, $999,000 had been drawn and outstanding under the December 2023 Loan and Transfer Agreements.

The Sponsor and the Company are jointly responsible for the payment of the principal amount of the December 2023 Loan within five business days of the completion of the Transactions with One Energy. In addition, within five business days of the completion of the Transactions with One Energy, One Energy will pay the December 2023 Lenders an additional one-time cash payment in the aggregate amount of $499,500. In addition, in the event the Transactions with One Energy are completed and a mandatory trigger of One Energy’s Series A preferred stock occurs, each December 2023 Lender will have a one-time option to cause the combined publicly-listed company to repurchase up to 360,000 shares of Class A common stock, on an as-converted basis, owned by such December 2023 Lender as a result of private purchases of One Energy’s shares prior to the Closing of the Transactions at $10.00 per share, which option is exercisable within the first thirty trading days following the completion of the Transactions with One Energy.

If the Transactions with One Energy are not completed, One Energy will issue to each December 2023 Lender the number of shares of its common stock equal to the principal amount of the December 2023 Loan at a price that values One Energy at its most recent private company equity valuation. If One Energy’s shares of common stock are not listed on a national securities exchange by December 31, 2026, each December 2023 Lender will also have a one-time option to cause One Energy to redeem all of their owned shares resulting from the agreement for an amount equal to the product of (x) 1.05 and (y) each December 2023 Lender’s pro rata amount of the December 2023 Loan.

On February 15, 2024, the Company entered into the February 2024 Loan and Transfer Agreements with the Sponsor, One Energy and the February 2024 Lenders, pursuant to which the February 2024 Lenders agreed to loan an aggregate of $333,000 to the Sponsor and the Sponsor loaned such amount to the Company. Neither the February 2024 Loan nor the February 2024 SPAC Loan will accrue any interest. As of June 30, 2024, $310,396 had been drawn and outstanding under the February 2024 SPAC Loan.

The Sponsor and the Company are jointly responsible for the payment of the principal amount of the February 2024 Loan within five business days of the completion of the Transactions with One Energy. In addition, within five business days of the completion of the Transactions with One Energy, One Energy will pay the February 2024 Lenders an additional one-time cash payment in the aggregate amount of $166,500. In addition, in the event the Transactions with One Energy are completed and a mandatory trigger of One Energy’s Series A preferred stock occurs, the February 2024 Lenders will have a one-time option to cause Pubco to repurchase up to an aggregate of 120,000 shares of One Energy Class A common stock, on an as-converted basis, owned by the February 2024 Lenders at $10.00 per share, which option is exercisable within the first thirty trading days following the completion of the Transactions with One Energy.

If the Transactions with One Energy are not completed, One Energy will issue to each February 2024 Lender the number of shares of its common stock equal to the principal amount of its February 2024 Loan at a price that values One Energy at its most recent private company equity valuation. If One Energy’s shares of common stock are not listed on a national securities exchange by December 31, 2026, each February 2024 Lender will also have a one-time option to cause One Energy to redeem all of its owned shares resulting from the February 2024 Loan and Transfer Agreement for an amount equal to the product of (x) 1.05 and (y) each February 2024 Lender’s pro rata amount of the February 2024 Loan.

On April 17, 2024, the Company, the Sponsor, One Energy and the April 17, 2024 Lenders entered into the April 2024 Loan and Transfer Agreements pursuant to which the April 17, 2024 Lenders, collectively, agreed to loan an aggregate of $350,000 to the Sponsor, which the Sponsor intended to loan to the Company, in each case in connection with the Second Extension Meeting and the Month-to-Month Extension payments. Neither the April 17, 2024 Loan nor the April 17, 2024 SPAC Loan will accrue interest.

In connection with the Second Extension Meeting and the Month-to-Month Extension payments, including the Sponsor’s obligations in respect thereof, on April 25, 2024, the Company and the April 2024 Investor entered into the April 2024 Subscription Agreement. Pursuant to the April 2024 Subscription Agreement, the April 2024 Investor agreed to contribute $400,000 to the Sponsor as the April 2024 Capital Contribution, which April 2024 Capital Contribution will generally be treated as part of the April 17, 2024 SPAC Loan, and was loaned by the Sponsor to the Company for working capital expenses and extensions as described above. In consideration of such April 2024 Capital Contribution, the Subscription Agreement contemplates that the Investor will receive, upon consummation, if any, of the proposed Transactions, 200,000 April 2024 Subscription Shares of Pubco. The April 2024 Subscription Shares will be issued within two business days after the Closing and will have certain registration rights described in the April 2024 Subscription Agreement. Under the terms of the April 2024 Subscription Agreement, following the Company’s repayment of the amount of the April 2024 Capital Contribution to the Sponsor, the Sponsor, in turn, shall pay an amount equal to the April 2024 Capital Contribution to the April 2024 Investor, within five business days of the Closing. In addition, within seven days of the Closing, Pubco will pay the Investor an additional one-time Cash Payment in the aggregate amount of$200,000.

Furthermore, in the event the Transactions are completed and a mandatory trigger of One Energy’s Series A preferred stock occurs prior to the Closing under the terms of the Certificate of Incorporation of One Energy the Investor will have a one-time option to cause Pubco to repurchase up to 600,000 shares of common stock owned by the April 2024 Investor as a result of private purchases of One Energy’ Series A shares prior to the Closing of the Transactions, at $10.00 per share, which option is exercisable within the first thirty trading days following the completion of the Transactions.

If the Transactions are not completed, the April 2024 Subscription Agreement provides that One Energy will issue to the April 2024 Investor the number of shares of One Energy common stock equal to the principal amount of its April 2024 Capital Contribution at a price that values One Energy at its most recent private company equity valuation. If One Energy’s shares of common stock are not listed on a national securities exchange by December 31, 2026, the April 2024 Investor will also have a one-time option to cause One Energy to redeem all of the One Energy shares then-owned by the Investor that are a direct result from the April 2024 Subscription Agreement for an amount equal to the product of (x) 1.05 and (y) the April 2024 Capital Contribution.

In connection with the Second Extension Meeting and the Month-to-Month Extension payments described above, including the Sponsor’s obligations in respect thereof, on June 6, 2024, the Company, the Sponsor and One Energy entered into the June 2024 Subscription Agreements with two June 2024 Investors. Pursuant to the June 2024 Subscription Agreements, the June 2024 Investors agreed to contribute an aggregate of $100,000 to the Sponsor as the June 2024 Capital Contribution, which will generally be treated as part of a loan made by the Sponsor to the Company and will be loaned by the Sponsor to the Company for working capital expenses and extensions, within two business days after the execution of the June 2024 Subscription Agreements. In consideration of such June 2024 Capital Contribution, the June 2024 Subscription Agreements contemplate that the June 2024 Investors

will receive, upon consummation, if any, of the Transactions with One Energy, an aggregate of 50,000 June 2024 Subscription Shares of TRTL Holding Corp., a Delaware corporation and a wholly-owned subsidiary of the Company which, assuming consummation of the Transactions, will be Pubco after the Closing of the Transactions. The June 2024 Subscription Shares will be issued within two business days after the Closing and will have certain registration rights described in the June 2024 Subscription Agreements. Under the terms of the June 2024 Subscription Agreements, following the Company’s repayment of the amount of the June 2024 Capital Contribution to the Sponsor, the Sponsor, in turn, shall pay an amount equal to the June 2024 Capital Contribution to the June 2024 Investors, within five business days of the Closing. In addition, within seven days of the Closing, Pubco will pay the June 2024 Investors an additional one-time cash payment in the aggregate amount of $50,000. As of June 30, 2024, the Company had $310,396 outstanding under the June 2024 Subscription Agreements which is recorded as subscription agreements on the condensed consolidated balance sheets.

Liquidity and Capital Resources

As of June 30, 2024, we had approximately $148,880 in operating cash and a working capital deficit of approximately $2,340,000.

Our liquidity needs prior to the consummation of our Initial Public Offering were satisfied through the payment of $25,000 from the Sponsor to cover certain expenses on behalf of our Company in exchange for the issuance of 8,625,000 Founder Shares, and the loan from our Sponsor of approximately $195,000 under an unsecured promissory note (the “Note”). We repaid the Note in full on July 22, 2021 and borrowings thereunder are no longer available.

Subsequent to the consummation of the Initial Public Offering, our liquidity has been satisfied through the net proceeds of $3.5 million from the consummation of the Initial Public Offering, the Over-Allotment and the sale of the Private Placement Warrants held outside of the Trust Account. In addition, in order to finance general working capital needs in connection with an initial Business Combination, our Sponsor or an affiliate of our Sponsor, or certain of our officers and directors may, but are not obligated to, provide us with funds as may be required (“Working Capital Loans”). On February 1, 2023, we issued the February 2023 Note to TortoiseEcofin Borrower in the amount of $500,000 to finance our general working capital needs. On February 1, 2023, March 9, 2023 and May 9, 2023, the Company borrowed $100,000, $50,000 and $185,000, respectively, under the February 2023 Note. As of June 30, 2024 and December 31, 2023, there were $335,000 outstanding under Working Capital Loans. On July 19, 2023, the Company issued the July 2023 Note in the principal amount of up to $1,000,000 to HCGP. The July 2023 Note was issued in connection with advances HCGP may make in the future to the Company for working capital expenses. The July 2023 Note bears no interest and is repayable in full upon the earlier of (i) the date on which the Company consummates its initial Business Combination and (ii) the date that the winding up of the Company is effective. At the election of HCGP, all or a portion of the unpaid principal amount of the July 2023 Note may be converted into Conversion Warrants at a price of $1.50 per warrant. The Conversion Warrants and their underlying securities are entitled to the registration rights set forth in the July 2023 Note. On August 7, 2023 and August 18, 2023, the Company borrowed $100,000 and $280,000, respectively, under the July 2023 Note.

In connection with our assessment of going concern considerations in accordance with FASB ASC Topic 205-40, “Presentation of Financial Statements-Going Concern,” management has determined that liquidity conditions and mandatory liquidation and subsequent dissolution raise substantial doubt about its ability to continue as a going concern. We intend to complete an initial Business Combination before the mandatory liquidation date; however, there can be no assurance that we will be able to consummate any business combination within the Combination Period. No adjustments have been made to the carrying amounts of assets or liabilities should we be required to liquidate after the Combination Period. The condensed consolidated financial statements do not include any adjustment that might be necessary if we are unable to continue as a going concern.

On June 13, 2023, we instructed Continental to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in an interest-bearing demand deposit account at a bank, with Continental continuing to act as trustee, until the earlier of the consummation of our initial Business Combination or our liquidation. As a result, following the liquidation of investments in the Trust Account, the remaining proceeds from the Initial Public Offering and Private Placement are no longer invested in U.S. government securities or money market funds invested in U.S. government securities.

Results of Operations

Our entire activity from February 3, 2021 (inception) through July 22, 2021 was in preparation for an Initial Public Offering, and since the completion of our Initial Public Offering through June 30, 2024, our activity had been limited to searching, negotiating and completing an initial Business Combination. We will not generate any operating revenues until the closing of our initial Business Combination.

For the three months ended June 30, 2024, we had net income of approximately $715,000, which consisted of approximately $1.9 million in interest income from cash held in the Trust Account, partly offset by approximately $84,000 of general and administrative expenses inclusive of $30,000 of administrative expenses with a related party, approximately $832,000 in change in fair value of derivative warrant liabilities and interest expense – debt discount of approximately $222,000.

For the three months ended June 30, 2023, we had net income of approximately $4.0 million, which consisted of approximately $3.8 million in interest income from investments and cash held in the Trust Account and approximately $800,000 in change in fair value of derivative warrant liabilities, partly offset by approximately $691,000 of general and administrative expenses inclusive of $30,000 of administrative expenses with a related party.

For the six months ended June 30, 2024, we had net income of approximately $1.7 million, which consisted of approximately $3.9 million in interest income from cash held in the Trust Account, partly offset by approximately $1.0 million of general and administrative expenses inclusive of $60,000 of administrative expenses with a related party, approximately $1 million in change in fair value of derivative warrant liabilities and interest expense – debt discount of approximately $309,000.

For the six months ended June 30, 2023, we had net income of approximately $8.9 million, which consisted of approximately $7.5 million in interest income from investments held in the Trust Account and approximately $2.4 million in change in fair value of derivative warrant liabilities, partly offset by approximately $1.0 million of general and administrative expenses inclusive of $60,000 of administrative expenses with a related party.

Factors That May Adversely Affect our Results of Operations

Our results of operations and our ability to complete an initial Business Combination may be adversely affected by various factors that could cause economic uncertainty and volatility in the financial markets, many of which are beyond our control. Our business could be impacted by, among other things, downturns in the financial markets or in economic conditions, increases in oil prices, inflation, increases in interest rates, supply chain disruptions, declines in consumer confidence and spending, public health considerations and geopolitical instability, such as the military conflicts in Ukraine and the Middle East. We cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact our business and our ability to complete an initial Business Combination.

Contractual Obligations

Registration and Shareholder Rights

Underwriting Agreement

The underwriters were paid an underwriting discount of $0.20 per Unit, or approximately $6.0 million in the aggregate, upon the closing of our Initial Public Offering. In addition, $0.35 per Unit, or approximately $10.5 million in the aggregate, will be payable to the underwriters for deferred underwriting commissions from the amounts held in the Trust Account solely in the event that that we complete an initial Business Combination, subject to the terms of the underwriting agreement.

We granted the underwriters a 45-day option from the date of our Initial Public Offering to purchase up to 4,500,000 additional Units at the Initial Public Offering price less the underwriting discounts and commissions. The underwriters exercised their over-allotment option in full on July 23, 2021, and on July 27, 2021, the underwriters purchased 4,500,000 additional Units, generating gross proceeds of $45.0 million.

Upon the consummation of the Over-Allotment on July 27, 2021, the underwriters were paid an additional underwriting commission of $900,000 and approximately $1.6 million in additional deferred underwriting commissions will become payable to the underwriters from the amounts held in the Trust Account solely in the event that we complete an initial Business Combination, subject to the terms of the underwriting agreement.

On July 17, 2023, three of the four underwriters for our Initial Public Offering, consisting of Barclays Capital Inc., Goldman Sachs & Co. LLC and Academy Securities, Inc., agreed to waive all rights to their respective portion of the underwriting commissions (or approximately $9.96 million of the total $12.075 million of the underwriting commissions) with respect to the Transactions with One Energy. One of the underwriters had further agreed to waive all rights to their respective portion of the underwriting commissions (approximately $4.83 million) with respect to the Company’s proposed business combination or to any future business combination.

Deferred Legal Fees Associated with Initial Public Offering and Certain Other Matters

We entered into an engagement letter to obtain legal advisory services in connection with our Initial Public Offering, pursuant to which our legal counsel agreed to defer half of their fees associated with the Initial Public Offering until the closing of our initial Business Combination and has agreed to the deferral of certain other legal expenses. As of June 30, 2024 and December 31, 2023, we recorded an aggregate of $174,000 for such deferred legal fees in the accompanying condensed consolidated balance sheets.

Administrative Support Agreement

On July 19, 2021, the Company entered into an administrative support agreement (the “Administrative Support Agreement”) with Tortoise Capital Advisors, L.L.C. (“Tortoise Capital Advisors”), pursuant to which, commencing on the date that the Company’s securities were first listed on the New York Stock Exchange through the earlier of consummation of a business combination and the date of the Company’s liquidation, the Company agreed to pay Tortoise Capital Advisors $10,000 per month for office space, utilities and secretarial and administrative support made available to the Company. For the three and six months ended June 30, 2024, the Company incurred $30,000 and $60,000, respectively, for such expenses, included as general and administrative expenses—related party on the accompanying unaudited condensed financial statements of operations. For the three and six months ended June 30, 2023, the Company incurred $30,000 and $60,000, respectively, for such expenses, included as general and administrative expenses—related party on the accompanying unaudited condensed financial statements of operations. On July 19, 2023, HCGP assumed Tortoise Capital Advisors’ rights and obligations under the Administrative Support Agreement.

In addition, the Sponsor, the Company’s executive officers and directors, and any of their respective affiliates will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential partner businesses and performing due diligence on suitable business combination targets. The Company’s audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, the Company’s executive officers or directors, or the Company’s or their affiliates. Any such payments prior to an initial Business Combination will be made using funds held outside the Trust Account. During the three and six months ended June 30, 2024, the Company incurred approximately $0 of such expenses. During the three and six months ended June 30, 2023, the Company incurred approximately $10,000 and $21,000, respectively, of such expenses.

Critical Accounting Estimates

The preparation of condensed consolidated financial statements and related disclosures in conformity with U.S. GAAP requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the condensed consolidated financial statements, and the reported amounts of income and expenses during the period reported. Actual results could materially differ from those estimates. One of the more significant estimates are in connection with determining the fair value of the derivative warrant liabilities.

Derivative Warrant Liabilities

The Public Warrants and the Private Placement Warrants are recognized as derivative liabilities in accordance with ASC 815. Accordingly, the Company recognizes the warrant instruments as liabilities at fair value and adjust the instruments to fair value at each reporting period. The liabilities are subject to re-measurement at each balance sheet date until exercised, and any change in fair value will be recognized in the Company’s statement of operations. The fair value of the Public Warrants and the Private Placement Warrants were initially measured at fair value using a Black-Scholes Option Pricing Method and Monte Carlo simulation, respectively. Subsequent to the Public Warrants being separately listed and traded from the Units, the fair value of the Public Warrants was measured based on their listed market price, and the fair value of the Private Placement Warrants was estimated by reference to the listed market price of the Public Warrants. The determination of the fair value of the warrant liabilities may be subject to change as more current information becomes available and accordingly the actual results could differ significantly. Derivative warrant liabilities are classified as non-current liabilities as their liquidation will not be reasonably expected to require the use of current assets or require the creation of current liabilities.

Off-Balance Sheet Arrangements

As of June 30, 2024, we did not have any off-balance sheet arrangements as defined in Item 303(a)(4)(ii) of Regulation S-K and did not have any commitments or contractual obligations.

JOBS Act

The Jumpstart Our Business Startups Act of 2021 (the “JOBS Act”) contains provisions that, among other things, relax certain reporting requirements for qualifying public companies. We qualify as an “emerging growth company” and, under the JOBS Act, are allowed to comply with new or revised accounting pronouncements based on the effective date for private (not publicly traded) companies. We are electing to delay the adoption of new or revised accounting standards, and as a result, we may not comply with new or revised accounting standards on the relevant dates on which adoption of such standards is required for non-emerging growth companies. As a result, our condensed consolidated financial statements may not be comparable to companies that comply with new or revised accounting pronouncements as of public company effective dates.

Additionally, we are in the process of evaluating the benefits of relying on the other reduced reporting requirements provided by the JOBS Act. Subject to certain conditions set forth in the JOBS Act, if, as an “emerging growth company,” we choose to rely on such exemptions we may not be required to, among other things, (a) provide an auditor’s attestation report on our system of internal controls over financial reporting pursuant to Section 404 of the JOBS Act, (b) provide all of the compensation disclosure that may be required of non-emerging growth public companies under the Dodd-Frank Wall Street Reform and Consumer Protection Act, (c) comply with any requirement that may be adopted by the Public Company Accounting and Oversight Board regarding mandatory audit firm rotation or a supplement to the auditor’s report providing additional information about the audit and the financial statements (auditor discussion and analysis) and (d) disclose certain executive compensation related items such as the correlation between executive compensation and performance and comparisons of our Chief Executive Officer’s compensation to median employee compensation. These exemptions will apply for a period of five years following the completion of our Initial Public Offering or until we are no longer an “emerging growth company,” whichever is earlier.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended June 30, 2024, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial officer have concluded that our disclosure controls and procedures were effective as of June 30, 2024.

Changes in Internal Control over Financial Reporting

There were no changes in our internal control over financial reporting (as such term is defined in Rules 13a-15(f) and 15d-15(f) of the Exchange Act) during the most recent fiscal quarter that have materially affected, or are reasonably likely to materially affect, our internal control over financial reporting.
