Helix Acquisition Corp. II

NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Helix Acquisition Corp. II (the “Company”) is a blank check company incorporated as a Cayman Islands exempted company on June 15, 2021. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses or entities (a “Business Combination”).

The Company has one subsidiary, Helix II Merger Sub Inc., a Delaware corporation, a direct wholly owned subsidiary of the Company incorporated on February 26, 2025. As of June 30, 2025, the subsidiary had no activity.

The Company is not limited to a particular industry or sector for purposes of consummating a Business Combination but intends to focus on healthcare and healthcare related industries. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of June 30, 2025, the Company had not commenced any operations. All activity for the period from June 15, 2021 (inception) through June 30, 2025 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination and negotiating and attempting to complete the proposed BBOT Business Combination (defined below). The Company does not expect to generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on February 8, 2024. On February 13, 2024, the Company consummated the Initial Public Offering of 18,400,000 Class A ordinary shares (the “Public Shares”), which includes the full exercise by the underwriter of its over-allotment option in the amount of 2,400,000 Public Shares, at $10.00 per Public Share, generating gross proceeds of $184,000,000, which is discussed in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 509,000 Class A ordinary shares (the “Private Placement Shares”) to Helix Holdings II, LLC (the “Sponsor”) at a price of $10.00 per Private Placement Share, or $5,090,000 in the aggregate, which is described in Note 4.

Transaction costs amounted to $8,180,834, consisting of $1,840,000 of upfront cash underwriting fee, $5,520,000 of deferred underwriting fee (see additional discussion on Note 6), and $820,834 of other offering costs.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of the Private Placement Shares, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The rules of Nasdaq require that the Company must complete one or more Business Combinations having an aggregate fair market value of at least 80% of the value of the assets held in the Trust Account (as defined below) (excluding the deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. The Company will only complete a Business Combination if the post transaction company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

Following the closing of the Initial Public Offering, on February 13, 2024, an amount of $184,000,000 ($10.00 per Public Share) from the net proceeds of the sale of the Public Shares and the sale of the Private Placement Shares, after deducting $1,840,000 in underwriting discounts and commissions paid upon the closing of the Initial Public Offering and an aggregate of $3,250,000 to pay fees and expenses in connection with the closing of the Initial Public Offering and for working capital following the closing, was placed in the trust account (“Trust Account”), and either held in cash, deposited into an interest bearing or non-interest bearing bank demand deposit account at a U.S. chartered commercial bank with consolidated assets of $100 billion or more, or invested in U.S. government securities within the meaning of Section 2(a)(16) of the Investment Company Act having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act, which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earliest of (i) the completion of a Business Combination and (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below.

The Company will provide the holders of the Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of the Business Combination, either (i) in connection with a general meeting called to approve the Business Combination or (ii) without a shareholder vote 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, equal to the aggregate amount then on deposit in the Trust Account, calculated as of two business days prior to the consummation of the Business Combination (initially anticipated to be $10.00 per Public Share), including interest (less taxes paid or payable), divided by the number of then issued and outstanding Public Shares, subject to certain limitations as described in the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 11, 2025. The per-share amount to be distributed to the Public Shareholders who properly redeem their Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 6). The Class A ordinary shares will be recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

Notwithstanding the foregoing, if the Company seeks shareholder approval of the Business Combination and the Company does not conduct redemptions pursuant to the tender offer rules, 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 Public Shares without the Company’s prior written consent.

The Sponsor has agreed (a) to waive its redemption rights with respect to any Founder Shares (as defined below), Private Placement Shares and Public Shares held by it in connection with the completion of a Business Combination and (b) not to propose an amendment to the Amended and Restated Memorandum and Articles of Association (i) to modify the substance or timing of the Company’s obligation to allow redemption in connection with the Company’s initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Completion Window (as defined below) or (ii) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment 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 Trust Account (less taxes paid or payable), divided by the number of then issued and outstanding Public Shares.

The Company will have until (i) the period ending on the date that is 24 months from the closing of the Initial Public Offering, or such earlier liquidation as the Company’s board of directors may approve, in which the Company must complete an initial Business Combination or (ii) such other time period in which the Company must complete an initial Business Combination pursuant to an amendment to the Company’s Amended and Restated Memorandum and Articles of Association (the “Completion Window”). However, if the Company has not completed a Business Combination within the Completion Window, the Company will as promptly as reasonably possible but not more thanten business days thereafter, redeem 100% of 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 (less taxes paid or payable and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and outstanding Public Shares, which redemption will constitute full and complete payment for the Public Shares and completely extinguish the rights of the Public Shareholders as shareholders (including the right to receive further liquidation or other distributions, if any), subject to the Company’s obligations under Cayman Islands law to provide for claims of creditors and subject to the other requirements of applicable law.

The Sponsor has agreed to waive its rights to liquidating distributions from the Trust Account with respect to the Founder Shares and Private Placement Shares if the Company fails to complete a Business Combination within the Completion Window. However, the Public Shares acquired by affiliates of the Sponsor in the Initial Public Offering, and any other Public Shares that the Sponsor or its affiliates may acquire thereafter, will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Completion Window. The underwriter has agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Completion Window, 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 will be less than the Initial Public Offering price per Share ($10.00).

In order to protect the amounts held in the Trust Account, the Sponsor has agreed that it will be liable to the Company if and to the extent any claims by a third party (other than the Company’s independent registered public accounting firm) 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 (1) $10.00 per Public Share (2) 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 trust assets, less taxes paid or payable and up to $100,000 of interest to pay dissolution expenses, provided that this liability will not apply to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and as to any claims under the Company’s indemnity of the underwriter of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). 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 (other than 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.

Proposed Business Combination withTheRas, Inc. (dba BridgeBio Oncology Therapeutics)

On February 28, 2025, the Company entered into a business combination agreement (as amended on June 17, 2025, the “BBOT Business Combination Agreement”, and the transactions contemplated thereby, including the Domestication and Merger, each as defined below, the “BBOT Business Combination”) withTheRas, Inc., a Delaware corporation (doing business as BridgeBio Oncology Therapeutics, “BBOT”) and Helix II Merger Sub, Inc., a Delaware corporation and a wholly-owned subsidiary of the Company (“Merger Sub”), pursuant to which, among other things and subject to the terms and conditions contained in the BBOT Business Combination Agreement (i) the Company will de-register in the Cayman Islands and transfer by way of continuation out of the Cayman Islands and into the State of Delaware so as to migrate to and domesticate as a Delaware corporation (the “Domestication”), and (ii) following the Domestication, Merger Sub will be merged with and into BBOT, as a result of which BBOT will be the surviving company and a wholly-owned subsidiary of the Company (the “Merger”). Consummation of the transactions contemplated by the BBOT Business Combination Agreement are subject to customary conditions of the respective parties, including the approval of the BBOT Business Combination Agreement, the Business Combination and certain other actions related thereto by the Company’s shareholders, and the availability of a minimum amount of aggregate transaction proceeds. For more information, see Note 6.

Going Concern Consideration

As of June 30, 2025, the Company had cash of $664,231 and working capital deficit of $1,752,040.

Until the consummation of an initial Business Combination, the Company has been and will be using the funds held outside the Trust Account for identifying and evaluating target businesses, performing due diligence on prospective target businesses, paying for travel expenditures, reviewing corporate documents and material agreements of prospective target businesses, and structuring, negotiating and completing an initial Business Combination.

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 would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of 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. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. If the Company completes a Business Combination, the Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1,500,000 of such Working Capital Loans may be convertible into private placement shares of the post-Business Combination entity at a price of $10.00 per share. The shares would be identical to the Private Placement Shares. As of June 30, 2025 and December 31, 2024, the Company had no outstanding borrowings under Working Capital Loans.

In connection with the Company’s assessment of going concern considerations in accordance with FASB Accounting Standards Update 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,”codified in the ASC 205-40, “Presentation of Financial Statements—Going Concern”, management has determined that the Company currently lacks the liquidity it needs to sustain operations for a reasonable period of time, which is considered to be at least one year from the date that the financial statements are issued as it expects to continue to incur significant costs in pursuit of its acquisition plans. In addition, management has determined that if the Company is unable to complete an initial Business Combination by February 14, 2026, then the Company will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. Management plans to consummate an initial Business Combination prior to the mandatory liquidation date. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after February 14, 2026.

NOTE 2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited consolidated condensed financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the U.S. Securities and Exchange Commission (“SEC”). Certain information or footnote disclosures normally included in financial statements prepared in accordance with GAAP have been consolidated condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited consolidated condensed financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.

The accompanying unaudited consolidated condensed financial statements should be read in conjunction with the Company’s Annual Report on Form 10-K for the year ended December 31, 2024, as filed with the SEC on March 11, 2025. The interim results for the three and six months ended June 30, 2025 are not necessarily indicative of the results to be expected for the year ending December 31, 2025 or for any future periods.

Principles of Consolidation

The accompanying consolidated financial statements include the accounts of the Company and its wholly-owned subsidiaries. All intercompany transactions have been eliminated.

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.

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 a 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 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 the unaudited consolidated condensed 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 unaudited consolidated condensed financial statements and the reported amounts of other income and expenses during the reporting period.

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 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.

Cash

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company has $664,231 and $1,697,777 in cash as of June 30, 2025 and December 31, 2024, respectively, and no cash equivalents as of such dates.

Marketable Securities Held in Trust Account

At June 30, 2025 and December 31, 2024, substantially all of the assets held in the Trust Account were held in U.S. Treasury bills. The Company accounts for its marketable securities as trading securities under ASC 320, “Investments—Debt and Equity Securities”, where securities are presented at fair value on the balance sheets. Gains and losses resulting from the change in fair value of marketable securities held in the Trust Account are included in interest earned on marketable securities held in Trust Account in the statements of operations. For the six months ended June 30, 2025, the Company has $4,064,267 of interest earned in the Trust Account of which $3,248,056 was invested in marketable securities and $816,211 of accrued interest will be invested in marketable securities. For the year ended December 31, 2024, the Company has $8,449,291 of interest earned in the Trust Account of which $7,358,108 was invested in marketable securities and $1,091,183 of accrued interest was invested in marketable securities. As of June 30, 2025 and December 31, 2024, the Company has not withdrawn any interest earned on the Trust Account.

Offering Costs

The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. Financial Accounting Standards Board (“FASB”) ASC 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. Offering costs allocated to the Public Shares were charged to temporary equity. Offering costs allocated to the Private Placement Shares were charged to additional paid-in capital.

Class A Redeemable Share Classification

The Public Shares contain a redemption feature which allows for the redemption of such Public Shares in connection with the Company’s liquidation, or if there is a shareholder vote or tender offer in connection with the Company’s initial Business Combination. In accordance with ASC 480-10-S99, the Company classifies Public Shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes change in redemption value immediately as it occurs and will adjust the carrying value of redeemable shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption amount value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, at June 30, 2025 and December 31, 2024, Class A ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of the Company’s balance sheets. At June 30, 2025 and December 31, 2024, the Class A ordinary shares subject to redemption reflected in the balance sheets are reconciled in the following table:

Income Taxes

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 major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of June 30, 2025 and December 31, 2024, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was $0 for the periods presented.

Net Income per Ordinary Share

The Company complies with accounting and disclosure requirements of the FASB ASC Topic 260, “Earnings Per Share.” Net income per ordinary share is computed by dividing net income per ordinary share by the weighted average number of ordinary shares outstanding during the period, excluding ordinary shares subject to forfeiture. Basic and diluted net income per ordinary share for Class A ordinary shares and Class B ordinary shares is calculated by dividing net income attributable to the Company by the weighted average number of Class A ordinary shares and Class B ordinary shares outstanding, allocated proportionally to each class of ordinary shares. This presentation assumes a Business Combination as the most likely outcome. Accretion associated with the redeemable Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

The following tables reflect the calculation of basic and diluted net income per ordinary share (in dollars, except per share amounts):

Concentration of Credit Risk

Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage 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.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short-term nature.

Share-Based Compensation

The Company records share-based compensation in accordance with FASB ASC Topic 718, “Compensation-Share Compensation” (“ASC 718”), guidance to account for its share-based compensation. It defines a fair value-based method of accounting for an employee share option or similar equity instrument. The Company recognizes all forms of share-based payments at their fair value on the grant date, which are based on the estimated number of awards that are ultimately expected to vest. Share-based payments are valued using a Black-Scholes option pricing model. Grants of share-based payment awards issued to non-employees for services rendered have been recorded at the fair value of the share-based payment, which is the more readily determinable value. The grants are amortized on a straight-line basis over the requisite service periods, which is generally the vesting period. If an award is granted, but vesting does not occur, any previously recognized compensation cost is reversed in the period related to the termination of service. Share-based compensation expenses are included in costs and operating expenses depending on the nature of the services provided in the consolidated condensed statements of operations.

Derivative Liabilities

The Company evaluates all of its financial instruments, including issued stock purchase warrants, 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 Subscription Agreements entered into on February 28, 2025 in connection with the BBOT Business Combination (see Note 6) do not qualify to be classified as a liability under ASC 480. The Company will recognize the Subscription Agreements at fair value under ASC 815 as of the contract inception date, and at each reporting period with changes in fair value recognized within earnings. The Company has followed the guidance in ASC 820 Fair Value Measurement. The initial fair value and the value as of February 28, 2025 of the Subscription Agreements issued was estimated using the underlying economic factors that influenced which of the events would occur, when they were likely to occur, and the specific terms that would be in effect at the time (i.e., stock price, exercise price, etc.).

Recent Accounting Standards

In March 2024, the FASB issued Accounting Standards Update (“ASU”) 2024-01, “Compensation - Stock Compensation (Topic 718): Scope Application of Profit Interest and Similar Awards” (“ASU 2024-01”). This ASU provides clarification on when profit interest awards should be accounted for similar to a cash bonus or profit-sharing arrangement in accordance with ASC 710 or as a share-based payment arrangement in accordance with ASC 718. The FASB issued this ASU to address diversity in the practice of accounting for profit interest awards. This ASU is effective for fiscal years beginning after December 15, 2024, and interim periods within fiscal years, with early adoption permitted. This ASU became effective as of December 31, 2024 and the Company's management adopted it in its financial statements and related disclosures. The adoption of ASU 2024-01 did not have a material impact on the accompanying financial statements and disclosures.

In November 2023, the FASB issued ASU 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures”. The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating officer decision maker (“CODM”), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. The ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities will be required to provide all annual disclosures currently required by Topic 280 in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in this ASU and existing segment disclosures in Topic 280. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. This ASU became effective as of December 31, 2024 and the Company’s management adopted in its financial statements and related disclosures. See Note 9 Segment Information in the accompanying notes to the financial statements for further detail.

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

NOTE 3. PUBLIC OFFERING

On February 13, 2024, pursuant to the Initial Public Offering, the Company sold 18,400,000 Public Shares, which includes a full exercise by the underwriter of their over-allotment option in the amount of 2,400,000 Public Shares, at a price of $10.00 per Public Share.

NOTE 4. PRIVATE PLACEMENT

On February 13, 2024, simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 509,000 Private Placement Shares at a price of $10.00 per Private Placement Share, for an aggregate purchase price of $5,090,000. A portion of the proceeds from the Private Placement Shares was added to the proceeds from the Initial Public Offering and are held in the Trust Account.

NOTE 5. RELATED PARTY TRANSACTIONS

Founder Shares

On June 19, 2021, Sponsor paid $25,000 to cover certain offering and formation costs of the Company in exchange for 2,875,000 Class B ordinary shares (the “Founder Shares”). The Founder Shares included an aggregate of up to 562,500 shares that were subject to forfeiture depending on the extent to which the underwriter’s over-allotment option was exercised, so that the number of Founder Shares would equal, on an as-converted basis, approximately 20% of the Company’s issued and outstanding ordinary shares after the Initial Public Offering (excluding any Public Shares purchased by the Sponsor in the Initial Public Offering and excluding the Private Placement Shares). On November 29, 2023, the Sponsor assigned 30,000 Founder Shares to each of the Company’s independent directors, Mark McKenna and John Schmid, and to the Company’s advisor, Andrew Phillips. On February 1, 2024, the Company effected a share capitalization with respect to the Class B ordinary shares of 1,437,500 shares, resulting in the Sponsor holding a total of 4,222,500 Founder Shares. On February 8, 2024, the Company effected a share capitalization with respect to the Class B ordinary shares of 287,500 shares, resulting in the Sponsor holding a total of 4,510,000 Founder Shares and the Company’stwo independent directors andone advisor each holding 30,000 Founder Shares, which were retroactively presented on the financial statements, with up to 600,000 Founder Shares held by the Sponsor subject to forfeiture depending on the extent to which the underwriter’s over-allotment option was exercised. On February 11, 2024, the underwriter of the Initial Public Offering delivered the Company a notice of its intention to fully exercise the over-allotment option and on February 13, 2024, simultaneously with the closing of the Initial Public Offering, the underwriter purchased the additional 2,400,000 Public Shares at a price of $10.00 per Public Share. Accordingly, the Founder Shares are no longer subject to forfeiture.

On February 8, 2025, the board of directors of the Company appointed Mr. Albert A. Holman, III, as an independent director. In connection with his appointment to the board of directors, the Company’s Sponsor transferred 30,000 of the Founder Shares held by it to Mr. Holman.

The Sponsor and the Company’s three independent directors and one advisor (the “Insiders”) have each agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earliest of (A) one year after the completion of a Business Combination and (B) subsequent to a Business Combination, (x) if the closing price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for share subdivisions, share dividends, rights issuances, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after a Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange or other similar transaction that results in all of the Public Shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property.

The sale or allocation of the Founder Shares to the Company’s directors on February 8, 2024, as described above, is within the scope of ASC 718. Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The fair value of the 90,000 Founder Shares transferred to the Company’s independent directors and advisor on November 29, 2023 is $309,600 or $3.44 per share. The Founder Shares were granted subject to a service condition (i.e., being part of the Company at the date of the Initial Public Offering through one year from the Initial Public Offering). Stock-based compensation will be recognized ratably from the date of the Initial Public Offering through the one-year anniversary of the Initial Public Offering in an amount equal to the number of Founder Shares times the grant date fair value per share less the amount initially received for the purchase of the Founder Shares.

The allocation of the Founder Shares to the Company’s director on February 8, 2025, as described above, is within the scope of ASC 718. Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the grant date. The fair value of the 30,000 Founder Shares transferred to the Company’s independent director on February 8, 2025 is $144,000 or $4.80 per share. The Founder Shares were granted to a service condition (i.e. in connection with the services as a member of the board of directors). Stock-based compensation will be recognized based on the award’s initial fair value upon grant date and recognized over the period in which the services are rendered.

Administrative Services and Indemnification Agreement

The Company entered into an agreement, commencing on February 8, 2024, through the earlier of the Company’s consummation of a Business Combination and its liquidation, to pay the Sponsor a total of $6,458 per month for office space, utilities and secretarial, and administrative support services. In addition, the Company has agreed that it will indemnify the Sponsor, members and managers and representatives of the Sponsor (collectively, “Sponsor Indemnitees”) from any claims arising out of or relating to the Initial Public Offering or the Company’s operations or conduct of the Company’s business or any claim against any Sponsor Indemnitees alleging any expressed or implied management or endorsement by Sponsor Indemnitees of any of the Company’s activities or any express or implied association between Sponsor Indemnitees, on the one hand, and the Company or any of its other affiliates, on the other hand. For the three and six months ended June 30, 2025, the Company incurred $19,374 and $38,748 in fees for these services, of which such amounts are shown as due to related party in the accompanying condensed balance sheets. For the three and six months ended June 30, 2024, the Company incurred $19,374 and $29,061 in fees for these services, respectively, of which such amounts are included in accrued expenses in the accompanying condensed balance sheets.

Promissory Note — Related Party

On June 19, 2021, as amended in October 2023, the Company issued an unsecured promissory note (the “Promissory Note”) to the Sponsor, pursuant to which the Company may borrow up to an aggregate principal amount of $300,000. The Promissory Note is non-interest bearing and payable on the earlier of (i) June 30, 2024 or (ii) the completion of the Initial Public Offering. As of June 30, 2025 and December 31, 2024, the Company had no amounts outstanding under the Promissory Note. Borrowing under the Promissory Note is no longer available.

Related Party Loans

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. If the Company completes a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of 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. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. If the Company completes a Business Combination, the Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $1,500,000 of such Working Capital Loans may be convertible into private placement shares of the post-Business Combination entity at a price of $10.00 per share. The shares would be identical to the Private Placement Shares. As of June 30, 2025 and December 31, 2024, the Company had no outstanding borrowings under Working Capital Loans.

*NOTE 6. COMMITMENTS ***

Registration Rights

The holders of the Founder Shares, Private Placement Shares and any shares that may be issued upon conversion of Working Capital Loans have registration rights pursuant to a registration rights agreement dated as of February 8, 2024 (the “Registration Rights Agreement”). The holders of these securities are entitled to make up to three demands, excluding short form demands, that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of a 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 lockup period. The Registration Rights Agreement does not contain liquidating damages or other cash settlement provisions resulting from delays in registering the Company’s securities. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The Company granted the underwriter a 45-day option to purchase up to 2,400,000 additional Public Shares to cover over-allotments at the Initial Public Offering price, less the underwriting discounts and commissions. On February 11, 2024, the underwriter delivered the Company a notice of its intention to fully exercise the over-allotment option and on February 13, 2024, simultaneously with the closing of the Initial Public Offering, the underwriter purchased the additional 2,400,000 Public Shares at a price of $10.00 per Public Share.

The underwriter was entitled to an upfront cash underwriting discount of $0.10 per Public Share, or $1,840,000 in the aggregate, paid upon the closing of the Initial Public Offering. In addition, the underwriter is entitled to a deferred fee of $0.30 per Public Share, or $5,520,000 in the aggregate. The deferred fee will become payable to the underwriter 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.

Business Combination Agreement

On February 28, 2025, the Company entered into the BBOT Business Combination Agreement by and among the Company, BBOT, and Merger Sub. The BBOT Business Combination Agreement provides, among other things, that on the terms and subject to the conditions set forth therein, (i) the Company will de-register in the Cayman Islands and transfer by way of continuation out of the Cayman Islands and into the State of Delaware so as to migrate to and domesticate as a Delaware corporation, and (ii) following the Domestication, Merger Sub will be merged with and into BBOT, as a result of which BBOT will be the surviving company and a wholly-owned subsidiary of the Company. The consummation of the Merger is referred to as the “Closing” and the date of the Closing is referred to as the “Closing Date.”

Other Agreements

The BBOT Business Combination Agreement contemplates the execution of various additional agreements and instruments, on or before the Closing, including, among others, the following:

Helix Support Agreement

In connection with the execution of the BBOT Business Combination Agreement, on February 28, 2025, certain Company shareholders and Insiders (the “Helix Supporting Shareholders”), including the Sponsor, three investment vehicles managed by Cormorant Asset Management, LP (“Cormorant” and, the investment vehicles managed by Cormorant, the “Cormorant Funds”) each holding Class A ordinary shares, and the independent directors and an advisor of the Company each holding Class B ordinary shares (the “Helix Existing Investors”), entered into a support agreement with the Company and BBOT (the “Helix Support Agreement”). Under the Helix Support Agreement, among other things, each Helix Supporting Shareholder agreed to vote, at any meeting of the shareholders of the Company, and in any action by written consent of the shareholders of the Company, all of such Helix Supporting Shareholders’ Class A ordinary shares and Class B ordinary shares (i) in favor of each of the Parent Proposals (as defined in the BBOT Business Combination Agreement), and any other matters necessary or reasonably requested by the Company for consummation of the Domestication, the Merger or any other transactions contemplated by the BBOT Business Combination Agreement and the approval of the Parent Proposals; (ii) against any Alternative Proposal or Alternative Transaction or any proposal relating to an Alternative Proposal or Alternative Transaction (as defined in the BBOT Business Combination Agreement, respectively); and (iii) in favor of any proposal sought by the Company to extend the deadline by which the Company must consummate its initial business combination. In addition, the Helix Support Agreement prohibits each Helix Supporting Shareholder from, among other things, selling, assigning or transferring any Class A ordinary shares or Class B ordinary shares held by such Helix Supporting Shareholder except to certain permitted transferees, until the earliest of (a) the effective time of the Merger, (b) such date and time as the BBOT Business Combination Agreement is terminated in accordance with its terms; (c) the liquidation of the Company; (d) the written agreement of each of the terminating Helix Supporting Shareholder(s), the Company and BBOT with respect to terminating the rights and obligations under the Helix Support Agreement of a specific Helix Supporting Shareholder or a subset of Helix Supporting Shareholders; and (e) the written agreement of all Helix Supporting Shareholders, the Company and BBOT to terminate the Helix Support Agreement in its entirety. Pursuant to the Helix Support Agreement, each of Cormorant Funds and its permitted transferees irrevocably and unconditionally covenants and agrees not to submit any Class A ordinary shares owned by it for redemption in connection with the BBOT Business Combination. Additionally, the Sponsor and Helix Existing Investors will comply with their non-redemption obligations as specified in the Letter Agreement.

Further, if and only if the Company Closing Cash (as defined in the BBOT Business Combination Agreement) is less than $400,000,000, the Sponsor will forfeit a number of shares of PubCo Common Stock (the “Contribution Shares”) equal to (a)3,360,000 multiplied by (b) one minus the number resulting from dividing (i) the Company Closing Cash by (ii) $400,000,000, with any fractional share rounded to the nearest whole number resulting from such product.

Each of the Sponsor and each Helix Existing Investor agreed to elect to convert their Class B ordinary shares into Class A ordinary shares immediately prior to the Domestication and to waive their rights under the Articles to have their Class B ordinary shares converted into Class A ordinary shares at a ratio of greater than one-to-one.

In addition, pursuant to the Helix Support Agreement, the Sponsor will, effective as of immediately prior to the Domestication and conditioned upon the Closing, forfeit and surrender to the Company such number of Class B ordinary shares (the “Sponsor Forfeited Shares”) held by the Sponsor equal to the quotient of (i) the difference between (A) the Redemption Price multiplied by 4,600,000 less (B) $46,000,000 divided by (ii) the Redemption Price (as defined in the BBOT Business Combination Agreement).

BBOT Written Consent and Support Agreements

Concurrently and immediately prior to the signing of the BBOT Business Combination Agreement, BBOT obtained and delivered to Company the written consents of a sufficient number of shares of BBOT capital stock required to approve the BBOT Business Combination Agreement, each ancillary agreement to which BBOT is a party, and the BBOT Business Combination.

Additionally, concurrently and immediately prior to the signing of the BBOT Business Combination Agreement, the Company, BBOT, and certain stockholders of BBOT (the “BBOT Supporting Stockholders”) entered into a support agreement (the “BBOT Support Agreement”). Pursuant to the BBOT Support Agreement, each BBOT Supporting Stockholder (i) agreed that each existing investor rights agreement of BBOT will automatically terminate upon the Closing, (ii) agreed not to make any proposal or offer that constitutes an Alternative Transaction, among other things, and (iii) waived and agreed not to exercise any rights of appraisal or rights to dissent it may have in connection with the Merger.

The BBOT Support Agreement also prohibits the BBOT Supporting Stockholders from, among other things, selling, assigning or transferring any capital stock of BBOT held by the BBOT Supporting Stockholders except to certain permitted transferees, until the earliest of (a) the effective time of the Merger, (b) such date and time as the BBOT Business Combination Agreement is terminated in accordance with its terms; and (c) the written agreement of all BBOT Supporting Stockholders, the Company and BBOT to terminate the agreement in its entirety.

Subscription Agreement

In connection with the BBOT Business Combination, on February 28, 2025, the Company entered into subscription agreements (the “Subscription Agreements”) with certain qualified institutional buyers, institutional accredited investors, and other accredited investors, including Cormorant and other existing shareholders of the Company (collectively, the “PIPE Investors”), pursuant to which, among other things, the Company agreed to issue and sell to the PIPE investors, and the PIPE Investors agreed to subscribe for and purchase an aggregate of approximately $260,000,000 of PubCo Common Stock (the “PIPE Shares”), at a purchase price equal to the Redemption Price (as defined in the BBOT Business Combination Agreement) (the “PIPE Investments”). Cormorant Funds subscribed for an aggregate of $75,000,000 of PIPE Investments.

The obligations of each party to consummate the PIPE Investments are conditioned upon, among other things, (i) the PubCo Common Stock having been approved for listing on Nasdaq Stock Market LLC; (ii) all conditions precedent to the closing of the BBOT Business Combination set forth in Article IX of the BBOT Business Combination Agreement having been satisfied or waived; and (iii) the absence of specified adverse laws, rules, regulations, judgments, decrees, executive orders or awards making the PIPE Investment illegal or otherwise prohibiting its consummation; (iv) no subscription agreement, side letter, or other agreement or understanding with any other PIPE Investor having been amended, modified, or waived in any manner that benefits such other PIPE Investor unless each PIPE Investor has been offered the same benefits; (v) the Company having received not less than $200 million in cash from the PIPE Investments; and (vi) no BBOT Material Adverse Effect or Helix Material Adverse Effect (each as defined in the BBOT Business Combination Agreement) having occurred.

Non-Redemption Agreement

The Non-Redeeming Holder also agreed to (i) not to transfer directly or indirectly the Non-Redeeming Shares held by it until earlier of (x) the Closing Date, (y) the termination of the BBOT Business Combination Agreement in accordance with its terms and (z) the termination of the Non-Redemption Agreement in accordance with its terms; and (ii) vote its Non-Redeeming Shares (A) in favor of the BBOT Business Combination Agreement, the Domestication and Merger and each other proposal brought by the Company in connection with the BBOT Business Combination and (B) in favor of any proposal brought by the Company to adjourn or postpone the shareholder’s meeting of the Company in connection with the BBOT Business Combination.

NOTE 8. FAIR VALUE MEASUREMENTS

The fair value of the Company’s financial assets and liabilities reflects management’s estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

At June 30, 2025, assets held in the Trust Account were comprised of $328 in cash and $196,513,230 in U.S. Treasury Bills. As of June 30, 2025, the Company did not withdraw any interest income from the Trust Account.

At December 31, 2024, assets held in the Trust Account were comprised of $634 in cash and $192,448,657 in U.S. Treasury Bills. As of December 31, 2024, the Company did not withdraw any interest income from the Trust Account.

The following table presents information about the Company’s assets that are measured at fair value on a recurring basis at June 30, 2025 and December 31, 2024 and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value:

NOTE 9. SEGMENT INFORMATION

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s chief operating decision maker (“CODM”), or group, in deciding how to allocate resources and assess performance.

The Company’s Chief Financial Officer has been identified as the CODM, who reviews the operating results for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only hasone reporting segment.

The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the statements of operations as net income or loss. The measure of segment assets is reported on the balance sheets as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:

The CODM reviews interest earned marketable securities held in Trust Account to measure and monitor shareholders value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the trust agreement. General and administrative expenses are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a business combination within the business combination period. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative costs, as reported on the statements of operations, are the significant segment expenses provided to the CODM on a regular basis. All other segment items included in net income or loss are reported on the statements of operations and described within their respective disclosures.

NOTE 10. SUBSEQUENT EVENTS

The Company evaluated subsequent events and transactions that occurred after the consolidated condensed balance sheet date up to the date that the consolidated condensed financial statements were issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the consolidated condensed financial statements.
