NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

SilverBox Corp IV (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on April 16, 2024. The Company was incorporated for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company has not selected any specific Business Combination target and the Company has not, nor has anyone on its behalf, initiated any substantive discussions, directly or indirectly, with any Business Combination target.

As of September 30, 2024, the Company had not commenced any operations. All activity for the period from April 16, 2024 (inception) through September 30, 2024 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on investments from the proceeds derived from the Initial Public Offering.

The Company’s sponsor is SilverBox Sponsor IV LLC, a Delaware limited liability company (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on August 15, 2024. On August 19, 2024, the Company consummated the Initial Public Offering of 20,000,000 units at $10.00 per unit (the “Units ” and, with respect to the shares of Class A ordinary shares included in the Units being offered, the “Public Shares”), which is discussed in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 455,000 units (the “Private Placement Units”), at a price of $10.00 per Private Placement Unit in a private placement to the Sponsor, generating gross proceeds of $4,550,000, which is described in Note 4.

Transaction costs amounted to $13,000,434, consisting of $1,700,000 of cash underwriting fee, $10,300,000 of deferred underwriting fee, $170,000 of expense reimbursement from the underwriters, and $1,170,434 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 Private Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination.

The Company must complete one or more initial Business Combinations having an aggregate fair market value of at least 80% of the value of the Trust Account (as defined below) (excluding any deferred underwriting commissions and taxes payable on the interest earned on the Trust Account) at the time of the signing a definitive agreement in connection with the 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 business sufficient for it not to be required to register as an investment company under the Investment Company Act 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to complete a Business Combination successfully.

Following the closing of the Initial Public Offering, on August 19, 2024, an amount of $201,000,000 ($10.05 per Unit) from the net proceeds of the sale of the Units and the sale of the Private Placement Units was placed in a Trust Account (“Trust Account”), located in the United States with Continental Stock Transfer & Trust Company acting as trustee, and will be invested only in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act, having a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 promulgated under the Investment Company Act which invest only in direct U.S. government treasury obligations. Except with respect to interest earned on the funds held in the Trust Account that may be released to the Company as described below, the funds held in the Trust Account will not be released from the Trust Account until the earliest to occur of (1) the Company’s completion of an initial Business Combination; (2) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to provide for the redemption of the Company’s Public Shares in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not consummate the initial Business Combination within the Completion Window from the closing of the Initial Public Offering or (B) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity; and (3) the redemption of all of the Company’s Public Shares if the Company has not completed an initial Business Combination within the Completion Window, subject to applicable law. The proceeds deposited in the Trust Account could become subject to the claims of the creditors, if any, which could have priority over the claims of the Company’s public shareholders.

The Company will provide its public shareholders with the opportunity to redeem, regardless of whether they abstain, vote for, or vote against, the initial Business Combination, all or a portion of their Public Shares upon the completion of the initial Business Combination either (1) in connection with a shareholders’ meeting called to approve the Business Combination or (2) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require the Company to seek shareholder approval under applicable law or stock exchange listing requirement. The shareholders will be entitled to redeem all or a portion of the Public Shares upon the completion of the initial Business Combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest, divided by the number of the outstanding Public Shares, subject to the limitations described herein. The amount in the Trust Account is initially anticipated to be $10.05 per Public Share.

The ordinary shares subject to redemption will be recorded at a 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.” In such case, the Company will proceed with a Business Combination if the Company has net tangible assets, after payment of the deferred underwriting commissions, of at least $5,000,001 upon such consummation of a Business Combination and, if the Company seeks shareholder approval, a majority of the issued and outstanding shares voted are voted in favor of the Business Combination.

The Company will have only 24 months from the closing of the Initial Public Offering to complete the initial Business Combination (the “Combination Period”). However, if the Company has not completed the initial Business Combination within the Combination Period or the Company does not otherwise seek shareholder approval to amend the amended and restated memorandum and articles of association to further extend the time to complete the initial Business Combination, the Company will (1) cease all operations except for the purpose of winding up; (2) as promptly as reasonably possible but no more than ten business days thereafter, subject to lawfully available funds therefor, 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, divided by the number of the outstanding Public Shares, which redemption will completely extinguish public shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any); and (3) as promptly as reasonably possible following such redemption, subject to the approval of the Company’s remaining shareholders and the Company’s board of directors, dissolve and liquidate, subject in each case to the Company’s obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor, directors and officers will enter into a letter agreement with the Company, pursuant to which they will agree to (1) waive their redemption rights with respect to any Founder Shares (as defined in Note 4) and any Public Shares held by them in connection with the completion of the initial Business Combination; (2) waive their redemption rights with respect to any Founder Shares and Public Shares held by them in connection with a shareholder vote to approve an amendment to the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to provide for the redemption of the Company’s Public Shares in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company does not consummate its initial Business Combination within the Combination Window or (B) with respect to any other provision relating to shareholders’ rights or pre-initial Business Combination activity; (3) waive their rights to liquidating distributions from the Trust Account with respect to any Founder Shares they hold if the Company fails to complete its initial Business Combination within the Combination Window (although they will be entitled to liquidating distributions from the Trust Account with respect to any Public Shares they hold if the Company fails to complete the initial business combination within the completion window) and (4) vote their Founder Shares and any public shares purchased during or after the Initial Public Offering (including in open market and privately negotiated transactions) in favor of the initial Business Combination (except that any public shares such parties may purchase in compliance with the requirements of Rule 14e-5 under the Securities Exchange Act of 1934 would not be voted in favor of approving the Business Combination transaction).

The Sponsor will agree 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 entered into a written letter of intent, confidentiality or similar agreement or Business Combination agreement, reduce the amount of funds in the Trust Account to below (1) $10.05 per Public Share or (2) the actual amount per share held in the Trust Account as of the date of the liquidation of the Trust Account if less than $10.05 per share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party or prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply 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 (as defined in Note 2). However, the Company has not asked the Sponsor to reserve for such indemnification obligations, nor has the Company independently verified whether the Sponsor has sufficient funds to satisfy its indemnity obligations and the Company believes that the Sponsor’s only assets are securities of the Company. Therefore, the Company cannot assure that the Sponsor would be able to satisfy those obligations. None of the Company’s officers or directors will indemnify the Company for claims by third parties including, without limitation, claims by vendors and prospective target businesses.

Liquidity and Capital Resources

As of September 30, 2024, the Company had $952,134 in cash and a working capital of $926,956. In connection with the Company's assessment of going concern considerations in accordance with ASC 205-40, “Going Concern,” and through the consummation of the Initial Public Offering, as of September 30, 2024, the Company has sufficient funds for the working capital needs of the Company until a minimum of one year from the date of issuance of these condensed financial statements. The Company cannot assure that its plans to consummate an Initial Business Combination will be successful.

The Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination.

NOTE 2. SIGNIFICANT ACCOUNTING POLICIES

Basis of Presentation

The accompanying unaudited 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 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 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 condensed financial statements should be read in conjunction with the Company’s prospectus for its Initial Public Offering as filed with the SEC on August 16, 2024, as well as the Company’s Current Report on Form 8-K, as filed with the SEC on August 23, 2024. The interim results for the period from April 16, 2024 (inception) through September 30, 2024, are not necessarily indicative of the results to be expected for the year ending December 31, 2024 or for any future periods.

Emerging Growth Company

The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startup 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 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 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 condensed financial statements in conformity with GAAP requires the Company’s 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 condensed financial statements and the reported amounts of revenues 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 unaudited condensed 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 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. The Company had $952,134 in cash and no cash equivalents as of September 30, 2024.

Investments Held in Trust Account

As of September 30, 2024, substantially all of the assets held in the Trust Account were held in U.S. Treasury Bills. The Company’s investments are presented at fair value on the condensed balance sheet. Gains and losses resulting from the change in fair value of investments held in the Trust Account are included in interest earned on investments held in Trust Account in the condensed statements of operations. As of September 30, 2024, the Company did not withdraw any interest earned on the Trust Account.

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under Financial Accounting Standards Board (“FASB”) ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the condensed balance sheet, primarily due to its short-term nature.

SILVERBOX CORP IV

NOTES TO CONDENSED FINANCIAL STATEMENTS

SEPTEMBER 30, 2024

(Unaudited)

Derivative Financial Instruments

The Company evaluates its financial instruments to determine if such instruments are derivatives or contain features that qualify as embedded derivatives in accordance with ASC Topic 815, “Derivatives and Hedging”. For derivative financial instruments that are accounted for as liabilities, the derivative instrument is initially recorded at its fair value on the grant date and is then re-valued at each reporting date, with changes in the fair value reported in the condensed statements of operations. The classification of derivative instruments, including whether such instruments should be recorded as liabilities or as equity, is evaluated at the end of each reporting period. Derivative liabilities are classified in the balance sheet as current or non-current based on whether or not net cash settlement or conversion of the instrument could be required within 12 months of the balance sheet date. The underwriters’ over-allotment option is deemed to be a freestanding financial instrument indexed on the contingently redeemable shares and was accounted for as a liability pursuant to ASC 480 since the option was not exercised at the Initial Public Offering. However, the underwriters have elected not to exercise the over-allotment option and the option expired, effective September 30, 2024, and the over-allotment option liability was derecognized in the condensed statements of operations.

Fair Value Measurement

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 include:

●

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 in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; 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.

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 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.

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. 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. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between Class A ordinary shares and warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. Offering costs allocated to the Class A ordinary shares were charged to temporary equity and offering costs allocated to the Public and Private Placement Warrants were charged to shareholders’ equity (deficit) as Public and Private Placement Warrants after management’s evaluation were accounted for under equity treatment.

Income Taxes

The Company accounts for income taxes under ASC 740, “Income Taxes’’ (“ASC 740”). ASC 740 requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statement and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carryforwards. ASC 740 additionally requires a valuation allowance to be established when it is more likely than not that all or a portion of deferred tax assets will not be realized.

ASC 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 September 30, 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 zero for the periods presented.

Class A Ordinary Shares Subject to Possible Redemption

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 possible redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur 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 September 30, 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 condensed balance sheet. As of September 30, 2024, the Class A ordinary shares subject to possible redemption reflected in the condensed balance sheet are reconciled in the following table:

Gross proceeds	$	200,000,000
Less:
Proceeds allocated to public warrants		(286,667)

Plus:
Accretion of carrying value to redemption value		15,795,403
Class A ordinary shares subject to possible redemption, September 30, 2024	$	202,266,313

Warrant Instruments

The Company accounts for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”), and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

For issued or modified warrants that meet all of the criteria for equity classification, the warrants are required to be recorded as a component of additional paid-in capital at the time of issuance. For issued or modified warrants that do not meet all the criteria for equity classification, the warrants are required to be recorded at their initial fair value on the date of issuance, and each balance sheet date thereafter. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at its assigned fair value.

Net Income per Ordinary Share

The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, “Earnings Per Share”. Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. This presentation contemplates a Business Combination as the most likely outcome, in which case, both classes of shares share pro rata in the net income of the Company. Accretion associated with the redeemable shares of Class A ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

The calculation of diluted net income per ordinary share does not consider the effect of the warrants issued in connection with the (i) IPO, and (ii) the private placement since the exercise of the warrants is contingent upon the occurrence of future events. The warrants are exercisable to purchase 6,818,333 Class A ordinary shares in the aggregate. For the three months ended September 30, 2024 and for the period from April 16, 2024 (inception) through September 30, 2024, the Company did not have any other dilutive securities or other contracts that could, potentially, be exercised or converted into ordinary shares and then share in the earnings of the Company. As a result, diluted net income per ordinary share is the same as basic net income per ordinary share for the periods presented.

The following table reflects the calculation of basic and diluted net income per ordinary share:


					For the Period from April
	For the Three Months				16, 2024 (Inception)

Recent Accounting Pronouncements

In June 2016, the FASB issued Accounting Standards Update (“ASU”) 2016-13, “Financial Instruments—Credit Losses (Topic 326): Measurement of Credit Losses on Financial Instruments” (“ASU 2016-13”). This update requires financial assets measured at amortized cost basis to be presented at the net amount expected to be collected. The measurement of expected credit losses is based on relevant information about past events, including historical experience, current conditions, and reasonable and supportable forecasts that affect the collectability of the reported amount. Since June 2016, the FASB issued clarifying updates to the new standard including changing the effective date for smaller reporting companies. The guidance is effective for fiscal years beginning after December 15, 2022, and interim periods within those fiscal years, with early adoption permitted. The Company adopted ASU 2016-13 on April 12, 2023. The adoption of ASU 2016-13 did not have a material impact on its unaudited condensed financial statements.

In August 2020, the FASB issued ASU 2020-06, “Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity’s Own Equity (Subtopic 815-40)” (“ASU 2020-06”), to simplify certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity’s own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity’s own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023 and should be applied on a full or modified retrospective basis. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted ASU 2020-06 as of April 16, 2024 (inception). There was no effect to the Company’s presented condensed financial statements.

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

NOTE 3. INITIAL PUBLIC OFFERING

Public Units

Pursuant to the Initial Public Offering, on August 19, 2024, the Company sold 20,000,000 Units, at a price of $10.00 per Unit. Each Unit consists of one Class A ordinary share and one-third of one redeemable warrant. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. Only whole warrants are exercisable. No fractional warrants will be issued upon separation of the units and only whole warrants will trade. The warrants will become exercisable 30 days after the completion of the initial Business Combination and will expire five years after the completion of the initial Business Combination or earlier upon redemption or liquidation.

Public Warrants

Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as discussed herein. The warrants will become exercisable 30 days after the completion of the initial Business Combination, and will expire five years after the completion of the Company’s initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

In addition, if (x) the Company issues additional Class A ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial 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 Company’s board of directors (including consideration of the market price) and, in the case of any such issuance to the initial shareholders or their affiliates, without taking into account any Founder Shares held by the initial shareholders or such affiliates, as applicable, prior to such issuance) (the “Newly Issued Price”), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial Business Combination on the date of the consummation of the initial Business Combination (net of redemptions), and (z) the volume weighted average trading price of the Company’s Class A ordinary shares during the 20 trading day period starting on the trading day following the effective date of the registration statement under the Securities Act covering the issuance of the Class A ordinary shares issuable upon exercise of the warrants (such price, the “Market Value”) is below $9.20 per share, the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Company will not be obligated to deliver any shares of ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act with respect to the ordinary shares underlying the warrants is then effective and a prospectus is current. No warrant will be exercisable and the Company will not be obligated to issue ordinary shares upon exercise of a warrant unless ordinary shares issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants. In no event will the Company be required to net cash settle any warrant.

(Unaudited)

In the event that a registration statement is not effective for the exercised warrants within specified time periods after the closing of the initial Business Combination, the purchaser of a unit containing such warrant will have paid the full purchase price for the unit solely for the share of ordinary shares underlying such unit.

Redemption of Public Warrants

Once the warrants become exercisable, the Company may redeem the outstanding warrants (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, which the Company refers to as the 30-day redemption period; and

●

if, and only if, the closing price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted) 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 (the “Reference Value”), provided that a registration statement under the Securities Act covering the issuance of 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-trading day measurement period.

If the Company calls the public warrants for redemption, management will have the option to require all holders that wish to exercise warrants to do so on a cashless basis. In the event of an exercise on a cashless basis, a holder would pay the warrant exercise price by surrendering the warrants for that number of Class A ordinary shares equal to the quotient obtained by dividing (x) the product of the number of Class A ordinary shares underlying the warrants, multiplied by the difference between the exercise price of the warrants and the “fair market value” (as defined in the next sentence) by (y) the fair market value. The “fair market value” for this purpose shall mean the average reported last sale price of the Class A ordinary shares for the 10 trading days ending on the third trading day prior to the date on which the notice of exercise is received by the warrant agent or on which the notice of redemption is sent to the holders of warrants, as applicable.

NOTE 4. RELATED PARTY TRANSACTIONS

Private Placement

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 455,000 Private Placement Units at a price of $10.00 per Private Placement Unit ($4,550,000 in the aggregate). Each Unit consists of one Class A ordinary share and one-third of one warrant. Each whole warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment. Only whole warrants are exercisable. A portion of the proceeds from the Private Placement Units were 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 Units will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

Twelve institutional investors (none of which are affiliated with any member of the Company’s management, the Sponsor or any other investor) (the “Sponsor Non-Managing Members”) purchased, indirectly through the purchase of sponsor non-managing membership interests, an aggregate of 350,000 of the 455,000 Private Placement Units at a price of $10.00 per Unit ($3,500,000 in the aggregate) in the private placement that closed simultaneously with the closing of the Initial Public Offering.

Founder Shares

On April 18, 2024, the Sponsor made a capital contribution of $25,000, or approximately $0.007 per share, to cover certain of the Company’s expenses, for which the Company issued 3,450,000 founder shares (the “Founder Shares”) to the Sponsor. In May 2024, the Company effected a share split for which an additional 2,300,000 Class B ordinary shares were issued and the Sponsor now holds 5,750,000 founder shares. All share and per share data is retrospectively presented. Up to 750,000 of the Founder Shares may be surrendered by the Sponsor for no consideration depending on the extent to which the underwriters’ over-allotment is exercised. As of September 30, 2024, the underwriters have elected not to exercise the over-allotment option and the option expired, and the 750,000 Founder Shares were cancelled, resulting in the Sponsor holding an aggregate of 5,000,000 Founder Shares.

Subject to each Sponsor Non-Managing Member purchasing, through the Sponsor, the Private Placement Units allocated to it in connection with the closing of the Initial Public Offering, the Sponsor will issue non-managing membership interests at a nominal purchase price to the Sponsor Non-Managing Members reflecting interests in an aggregate of 2,800,000 Founder Shares held by the Sponsor.

Promissory Note

On April 18, 2024, the Sponsor agreed to loan the Company up to $300,000 to be used for a portion of the expenses of the Initial Public Offering. This loan was non-interest bearing, unsecured and due at the earlier of December 31, 2024 or the closing of the Initial Public Offering. The Company repaid the outstanding balance of the note at the closing of the Initial Public Offering on August 19, 2024. Borrowings under the promissory note are no longer available.

Administrative Support Agreement

The Company entered into an agreement, commencing on August 15, 2024, through the earlier of the Company’s consummation of a Business Combination and its liquidation, to pay the Sponsor a total of $15,000 per month for office space, secretarial, administrative and shared personnel support services. As of September 30, 2024, there were $22,500 incurred and accrued under the Administrative Support Agreement.

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 directors and officers 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. The Working Capital Loans would either be repaid upon consummation of a Business Combination, without interest, or, at the lender’s discretion, up to $2,500,000 of such Working Capital Loans may be convertible into units of the post-Business Combination entity at a price of $10.00 per units. The units and the underlying securities would be identical to the Private Placement Units. As of September 30, 2024, there were no amounts outstanding under the Working Capital Loans.

NOTE 5. COMMITMENTS AND CONTINGENCIES

Risks and Uncertainties

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the recent escalation of the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the escalation of the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyberattacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the escalation of the Israel-Hamas conflict and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial business combination and any target business with which the Company may ultimately consummate an initial business combination.

Registration Rights

The holders of the (i) Founder Shares, which were issued in a private placement prior to the closing of the Initial Public Offering, (ii) Private Placement Units, which will be issued in a private placement simultaneously with the closing of the Initial Public Offering and the Class A ordinary shares underlying such Private Placement Warrants and (iii) Private Placement Warrants that may be issued upon conversion of Working Capital Loans have registration rights to require the Company to register a sale of any of the Company’s securities held by them pursuant to a registration rights agreement. 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 initial 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 Initial Public Offering to purchase up to 3,000,000 additional Units to cover over-allotments, if any, at the Initial Offering price less the underwriting discounts and commissions. The over-allotment option remains open since the close of the Initial Public Offering. As of September 30, 2024, the underwriters have elected not to exercise the over-allotment option and the option expired.

The underwriters were entitled to a cash underwriting discount of $1,700,000 or 0.85% of the gross proceeds of the units sold in the Initial Public Offering, which was paid on August 19, 2024, the closing of the Initial Public Offering. Additionally, the underwriters are entitled to a deferred underwriting discount of 5.15% of the gross proceeds of the Initial Public Offering held in the Trust Account, $10,300,000 in the aggregate upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.

SilverBox Securities LLC, an affiliate of the Sponsor (“SilverBox Securities”), acted as an independent financial advisor in connection with the Initial Public Offering. For financial advisory services provided by SilverBox Securities, the Company paid SilverBox Securities a fee in an amount equal to $170,000, which was reimbursed by the underwriters to the Company. In addition, SilverBox Securities is entitled to $2,030,000, which will be paid to SilverBox Securities upon the closing of the initial business combination.

NOTE 6. SHAREHOLDERS’ DEFICIT

Preference shares — The Company is authorized to issue 1,000,000 preference shares with a par value of $0.0001 and with such designations, voting and other rights and preferences as may be determined from time to time by the Company’s board of directors. As of September 30, 2024, 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. At September 30, 2024, there are 455,000 Class A ordinary shares issued and outstanding, excluding 20,000,000 Class A ordinary shares subject to possible redemption.

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. As of September 30, 2024, there were 5,000,000 Class B ordinary shares issued and outstanding.

Holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the Company’s shareholders except as required by law. Unless specified in the Company’s amended and restated memorandum and articles of association, or as required by applicable provisions of law or applicable stock exchange rules, the affirmative vote of a majority of the Company’s ordinary shares that are voted is required to approve any such matter voted on by its shareholders.

Prior to the consummation of the initial Business Combination, only holders of Class B ordinary shares will have the right to vote on the appointment or removal of directors. Holders of the Class A ordinary shares will not be entitled to vote on the appointment or removal of directors during such time. These provisions of the Company’s amended and restated memorandum and articles of association may only be amended if approved by a majority of at least 90% of its ordinary shares voting at a shareholders’ meeting.

The Class B ordinary shares will automatically convert into Class A ordinary shares upon the consummation of the initial Business Combination on a one-for-one basis, subject to adjustment for share subdivisions, share dividends, reorganizations, recapitalizations and the like, and subject to further adjustment. In the case that additional Class A ordinary shares or equity-linked securities are issued or deemed issued in connection with the initial Business Combination, the number of Class A ordinary shares issuable upon conversion of all Founder Shares will equal, in the aggregate, on an as-converted basis, 20% of the total number of shares of Class A ordinary shares outstanding after such conversion, including the total number of Class A ordinary shares issued, or deemed issued or issuable upon conversion or exercise of any equity-linked securities or rights issued or deemed issued, by the Company in connection with or in relation to the consummation of the initial Business Combination, excluding any Class A ordinary shares or equity-linked securities or rights exercisable for or convertible into Class A ordinary shares issued, or to be issued, to any seller in the initial Business Combination and any Private Placement Units issued to the Sponsor, officers or directors upon conversion of Working Capital Loans; provided that such conversion of Founder Shares will never occur on a less than one-for-one basis.

NOTE 7. 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).

At September 30, 2024, assets held in the Trust Account were comprised of $927 in cash and $202,265,386 in U.S. Treasury bills. During the period from April 16, 2024 (inception) through September 30, 2024, the Company did not withdraw any interest income from the Trust Account.

Certain information contained in the discussion and analysis set forth below includes forward-looking statements that involve risks and uncertainties.

Special Note Regarding Forward-Looking Statements

This Quarterly Report includes “forward-looking statements” within the meaning of Section 27A of the Securities Act of 1933 and Section 21E of the Exchange Act that are not historical facts and involve risks and uncertainties that could cause actual results to differ materially from those expected and projected. All statements, other than statements of historical fact included in this Form 10-Q including, without limitation, statements in this “Management’s Discussion and Analysis of Financial Condition and Results of Operations” regarding the completion of the Proposed Business Combination (as defined below), the Company’s financial position, business strategy and the plans and objectives of management for future operations, are forward-looking statements. Words such as “expect,” “believe,” “anticipate,” “intend,” “estimate,” “seek” and variations and similar words and expressions are intended to identify such forward-looking statements. Such forward-looking statements relate to future events or future performance, but reflect management’s current beliefs, based on information currently available. A number of factors could cause actual events, performance or results to differ materially from the events, performance and results discussed in the forward-looking statements, including that the conditions of the Proposed Business Combination are not satisfied. For information identifying important factors that could cause actual results to differ materially from those anticipated in the forward-looking statements, please refer to the Risk Factors section of the Company’s final prospectus for its Initial Public Offering filed with the U.S. Securities and Exchange Commission (the “SEC”). The Company’s securities filings can be accessed on the EDGAR section of the SEC’s website at www.sec.gov. Except as expressly required by applicable securities law, the Company disclaims any intention or obligation to update or revise any forward-looking statements whether as a result of new information, future events or otherwise.

Overview

We are a blank check company incorporated in the Cayman Islands on April 16, 2024 for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or other similar Business Combination with one or more businesses. We intend to effectuate our Business Combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement Warrants, our shares, debt or a combination of cash, shares and debt.

We expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete a Business Combination will be successful.

Results of Operations

We have neither engaged in any operations nor generated any revenues to date. Our only activities from April 16, 2024 (inception) through September 30, 2024 were organizational activities and those activities necessary to prepare for the Initial Public Offering, described below. We do not expect to generate any operating revenues until after the completion of our Business Combination. Subsequent to the Initial Public Offering, we generate non-operating income in the form of interest income on investments held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the three months ended September 30, 2024, we had a net income $1,382,148, which consisted of change in fair value of over-allotment option liability of $306,504 and interest earned on investments held in Trust Account of $1,266,313, offset by general and administrative costs of $190,669.

For the period from April 16, 2024 (inception) through September 30, 2024, we had a net income $1,358,488, which consisted of change in fair value of over-allotment option liability of $306,504 and interest earned on investments held in Trust Account of $1,266,313, offset by general and administrative costs of $214,329.

Liquidity and Capital Resources

On August 19, 2024, we consummated the Initial Public Offering of 20,000,000 Units at $10.00 per Units. Simultaneously with the closing of the Initial Public Offering, we consummated the sale of an aggregate of 455,000 Private Placement Units at a price of $10.00 per Private Placement Unit, in a private placement to the Sponsor, generating gross proceeds of $4,550,000.

For the period from April 16, 2024 (inception) through September 30, 2024, cash used in operating activities was $314,085. Net income of $1,358,488 was affected by interest earned on investments held in the Trust Account of $1,266,313, formation costs paid by Sponsor in exchange for issuance of Class B ordinary shares of $15,524 and change in fair value of over-allotment option liability of $306,504. Changes in operating assets and liabilities used $115,280 of cash for operating activities.

As of September 30, 2024, we had investments held in the Trust Account of $202,266,313 (including approximately $1,266,313 of interest income) consisting of U.S. Treasury Bills with a maturity of 185 days or less. We may withdraw interest from the Trust Account to pay taxes, if any. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

As of September 30, 2024, we had cash of $952,134. We intend to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment. Up to $2,500,000 of such loans (the “Working Capital Loans”) may be convertible into units of the post-Business Combination entity at a price of $10.00 per unit. The units and the underlying securities would be identical to the Private Placement Units and the underlying securities of such Private Placement Units.

We do not believe we will need to raise additional funds in order to meet the expenditures required for operating our business. However, if our estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our Business Combination. Moreover, we may need to obtain additional financing either to complete our Business Combination or because we become obligated to redeem a significant number of our Public Shares upon consummation of our Business Combination, in which case we may issue additional securities or incur debt in connection with such Business Combination.

Off-Balance Sheet Arrangements

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of September 30, 2024. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.

Contractual obligations

We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay the Sponsor a total of $15,000 per month for office space, secretarial, administrative and shared personnel support services.

The underwriters were entitled to a cash underwriting discount of $1,700,000 or 0.85% of the gross proceeds of the units sold in the Initial Public Offering, which was paid on August 19, 2024. Additionally, the underwriters are entitled to a deferred underwriting discount of 5.15% of the gross proceeds of the Initial Public Offering held in the Trust Account, $10,300,000 in the aggregate upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement.

Critical Accounting Policies and Estimates

The preparation of the financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America 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 financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. The Company has not identified any critical accounting estimates but have identified the following critical accounting policies:

Class A Ordinary Shares Subject to Possible Redemption

We account for our ordinary shares subject to possible conversion in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” Ordinary shares subject to mandatory redemption are classified as a liability instrument and measured at fair value. Conditionally redeemable ordinary shares (including 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 our control) are classified as temporary equity. At all other times, ordinary shares are classified as shareholders’ deficit. Our ordinary shares feature certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, as of September 30, 2024, ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders’ deficit section of our balance sheets.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable ordinary shares to equal the redemption value at the end of each reporting period. Increases or decreases in the carrying amount of the redeemable ordinary shares are affected by charges against additional paid-in capital (to the extent available) and accumulated deficit.

Warrant Instruments

We account for warrants as either equity-classified or liability-classified instruments based on an assessment of the warrant’s specific terms and applicable authoritative guidance in FASB ASC 480, “Distinguishing Liabilities from Equity” (“ASC 480”), and ASC 815, “Derivatives and Hedging” (“ASC 815”). The assessment considers whether the warrants are freestanding financial instruments pursuant to ASC 480, meet the definition of a liability pursuant to ASC 480, and whether the warrants meet all of the requirements for equity classification under ASC 815, including whether the warrants are indexed to the Company’s own ordinary shares and whether the warrant holders could potentially require “net cash settlement” in a circumstance outside of the Company’s control, among other conditions for equity classification. This assessment, which requires the use of professional judgment, is conducted at the time of warrant issuance and as of each subsequent quarterly period end date while the warrants are outstanding.

Recent Accounting Standards

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 financial statements.

Item 3. Quantitative and Qualitative Disclosures About Market Risk

Not required for smaller reporting companies.

Item 4. Controls and Procedures

Evaluation of Disclosure Controls and Procedures

Disclosure controls and procedures are controls and other procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures include, without limitation, controls and procedures designed to ensure that information required to be disclosed in our reports filed or submitted under the Exchange Act is accumulated and communicated to Management, including our Chief Executive Officer and Chief Financial Officer (together, the “Certifying Officers”), 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 Certifying Officers, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on the foregoing, our Certifying Officers concluded that our disclosure controls and procedures were effective as of the end of the quarterly period ended September 30, 2024.

Changes in Internal Control over Financial Reporting

There was no change in our internal control over financial reporting that occurred during the fiscal quarter of 2024 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.
