**NOTES TO CONDENSED FINANCIAL STATEMENTS**

**JUNE 30, 2025**

**(Unaudited)**

**NOTE 1. DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS**

Mountain Crest Acquisition Corp. V (the "Company") is a blank check company that was incorporated in Delaware on April 8, 2021. The Company was formed for the purpose of effecting a merger, capital stock exchange, asset acquisition, stock purchase, reorganization or similar Business Combination with one or more businesses (the "Business Combination"). Although the Company is not limited to a particular industry or sector for purposes of consummating a Business Combination, the Company intends to focus its search on private companies in North America and Asia Pacific regions that have positive operating cash flow or compelling economics and clear paths to positive operating cash flow, significant assets, and successful management teams that are seeking access to the U.S. public capital markets. 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 April 8, 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. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering.

The registration statement for the Company's Initial Public Offering was declared effective on November 12, 2021. On November 16, 2021, the Company consummated the Initial Public Offering of 6,000,000 units (the "Units") and, with respect to the shares of common stock, par value $0.0001 per share (the "Common Stock") included in the Units sold, the public shares sold in the Initial Public Offering (the "Public Shares") at $10.00 per Unit, generating gross proceeds of $60,000,000, which is described in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 205,000 units (the "Private Units") at a price of $10.00 per Private Unit in a private placement to Mountain Crest Global Holdings LLC (the "Sponsor") generating gross proceeds of $2,050,000, which is described in Note 4.

Following the closing of the Initial Public Offering on November 16, 2021, an amount of $60,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Units was placed in a trust account (the "Trust Account"), which was invested in money market funds, within the meaning set forth in Section 2(a)(16) of the Investment Company Act of 1940, as amended (the "Investment Company Act"), with a maturity of 180 days or less or in any open-ended investment company that holds itself out as a money market fund meeting the conditions of Rule 2a-7 of the Investment Company Act, as determined by the Company, until the earlier of: (i) the consummation of a Business Combination or (ii) the distribution of the funds in the Trust Account as described below.

On November 18, 2021, the underwriters fully exercised their over-allotment option, resulting in an additional 900,000 Units issued for an aggregate amount of $9,000,000. In connection with the underwriters' full exercise of their over-allotment option, the Company also consummated the sale of an additional 18,000 Private Units at $10.00 per Private Unit, generating total proceeds of $180,000. A net total of $9,000,000 was deposited into the Trust Account, bringing the aggregate proceeds held in the Trust Account to $69,000,000.

Transaction costs amounted to $5,090,361 consisting of $1,380,000 of underwriting fees, $2,070,000 of deferred underwriting fees and $1,640,361 of other offering costs (which includes $1,383,617 of Representative Shares (as defined in Note 6) at fair value. See Note 6).

**MOUNTAIN CREST ACQUISITION CORP. V**

**NOTES TO CONDENSED FINANCIAL STATEMENTS**

**JUNE 30, 2025**

**(Unaudited)**

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 Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. The Company's initial Business Combination must be with one or more target businesses that together have a fair market value equal to at least 80% of the balance in the Trust Account (as defined below) (less any deferred underwriting commissions and net of amounts previously released to the Company to pay its tax obligations) at the time of the signing of an agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target sufficient for it not to be required to register as an investment company under the Investment Company Act. There is no assurance that the Company will be able to successfully effect a Business Combination.

The Company will provide its holders of the outstanding Public Shares (the "public stockholders") with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a stockholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek stockholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The stockholders will be entitled to redeem their shares for a pro rata portion of the amount then on deposit in the Trust Account (initially $10.00 per share, plus any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations). The per-share amount to be distributed to stockholders who redeem their shares will not be reduced by the deferred underwriting commission the Company will pay to the underwriters (as discussed in Note 6).

The Company will proceed with a Business Combination if a majority of the outstanding shares voted are voted in favor of the Business Combination. If a stockholder vote is not required by law and the Company does not decide to hold a stockholder vote for business or other legal reasons, the Company will, pursuant to its Amended and Restated Certificate of Incorporation, as amended (the "Charter"), conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission ("SEC"), and file tender offer documents with the SEC prior to completing a Business Combination. If, however, stockholder approval of the transaction is required by law, or the Company decides to obtain stockholder approval for business or other legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules. If the Company seeks stockholder approval in connection with a Business Combination, the Company's Sponsor has agreed to (a) vote its Insider Shares (as defined in Note 5), Private Shares and any Public Shares held by it in favor of a Business Combination and (b) not to redeem any shares in connection with a stockholder vote to approve a Business Combination or sell any such shares to the Company in a tender offer in connection with a Business Combination. Additionally, each public stockholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction.

Notwithstanding the above, if the Company seeks stockholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Charter provides that a public stockholder, together with any affiliate of such stockholder or any other person with whom such stockholder 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% or more of the Public Shares, without the prior consent of the Company.

**MOUNTAIN CREST ACQUISITION CORP. V**

**NOTES TO CONDENSED FINANCIAL STATEMENTS**

**JUNE 30, 2025**

**(Unaudited)**

The Sponsor has agreed to (i) waive its redemption rights with respect to Insider Shares, Private Shares and any Public Shares it may acquire during or after the Initial Public Offering in connection with the consummation of a Business Combination and (ii) not to propose an amendment to the Company's Charter that would affect the substance or timing of the Company's obligation to redeem 100% of its Public Shares if the Company does not complete a Business Combination, unless the Company provides the public stockholders an opportunity to redeem their Public Shares in conjunction with any such amendment. However, the Sponsor will be entitled to liquidating distributions with respect to any Public Shares acquired if the Company fails to consummate a Business Combination or liquidates within the period of time for the Company to complete a Business Combination (the "Combination Period").

The Company initially had until November 16, 2022 (or until February 16, 2023 if the Company had executed a definitive agreement for a Business Combination by November 16, 2022 but had not completed the Business Combination by such date) to consummate a Business Combination. On October 19, 2022, upon the upon the execution of a Business Combination Agreement, the Combination Period under its Charter was extended for a period of 3 months from November 16, 2022 to February 16, 2023. Subsequently, as approved by its stockholders at the special meeting of stockholders held on December 20, 2022, the Company entered into an amendment to the Investment Management Trust Agreement, dated as of November 12, 2021, with Continental Stock Transfer & Trust Company, on December 20, 2022 (the "Trust Amendment"). Pursuant to the Trust Amendment, the Company extended the Combination Period from February 16, 2023 to May 16, 2023 by depositing $300,000 into the Company's trust account (the "Trust Account") on February 15, 2023 (Note 6).

In connection with the stockholders' vote at the special meeting of stockholders held by the Company on December 20, 2022, 4,965,892 shares were tendered for redemption.

On April 3, 2023, the Company received a notice from the Nasdaq Stock Market LLC ("Nasdaq") stating that the Company's listed securities failed to satisfy the $50,000,000 market value of listed securities ("MVLS") requirement for continued listing on The Nasdaq Global Market (the "Global Market") in accordance with Nasdaq Listing Rule 5450(b)(2)(A) (the "MVLS Requirement") based upon the Company's MVLS for the 30 consecutive business days prior to the date of the notice. In accordance with Nasdaq Listing Rule 5810(c)(3)(A), the Company was provided a period of 180 calendar days, or until October 2, 2023, in which to regain compliance with the MVLS Requirement.

On April 7, 2023, the Company submitted its application to transfer the listing of its securities from the Global Market to The Nasdaq Capital Market (the "Capital Market").

On May 12, 2023, the Company held a special meeting of stockholders, at which the Company's stockholders approved an amendment (the "Extension Amendment") to the Company's Charter, giving the Company the right to extend Combination Period from May 16, 2023 to February 16, 2024. In connection with the Extension Amendment, stockholders holding 1,405,134 shares of redeemable Common Stock exercised their right to redeem such shares for a pro rata portion of the funds in the Trust Account.

On May 18, 2023, the Company received a second notice (the "May 18, 2023 Notice") from Nasdaq, stating that the Company no longer satisfies the requirement to maintain a minimum of 1,100,000 publicly held shares (the "PHS Requirement") for continued listing on the Global Market, according to the number of publicly held shares reported on its Form 8-K for May 12, 2023. The Company was provided 45 calendar days, or until July 3, 2023, to submit a plan to Nasdaq to regain compliance with the PHS Requirement.

On June 27, 2023, the Company received a third notice from Nasdaq stating that the Company's listed securities failed to maintain a minimum Market Value of Publicly Held Shares ("MVPHS") of $15,000,000 which is a requirement for continued listing on the Global Market in accordance with Nasdaq Listing Rule 5450(b)(3)(C) (the "MVPHS Requirement") based upon the Company's MVPHS for the 30 consecutive business days prior to the date of the notice. In accordance with Nasdaq Listing 5810(c)(3)(D), the Company was provided a period of 180 calendar days, or until December 26, 2023, in which to regain compliance with the MVPHS Requirement.

On June 30, 2023, in response to Nasdaq's May 18, 2023 Notice, the Company submitted a plan to Nasdaq to regain compliance with the PHS Requirement.

On July 18, 2023, the Company received a determination letter from Nasdaq advising it that the Nasdaq Staff has accepted the Company's plan to regain compliance with the PHS Requirement provided that, on or before November 14, 2023, the Company must file with the SEC and Nasdaq a public document containing its current total shares outstanding and a beneficial ownership table in accordance with the SEC Proxy Rules. If the Company fails to file such public document by November 14, 2023, the Company may receive a notice that its securities will be delisted. In that case, the Company will have the opportunity to appeal that decision to a Listing Qualifications Panel.

As approved by its stockholders at the annual meeting held on August 21, 2023, the Company filed the No. 3 amendment to the Charter (a) to modify the terms and extend the Combination Period to November 16, 2024, provided that the Company deposits into the Trust Account an amount equal to $0.10 per outstanding Public Share for each three-month extension commencing on November 17, 2023 by revising paragraph E of Article Sixth of the Charter; (b) to eliminate the requirement to maintain $5,000,001 of net tangible book value prior to or upon consummation of a Business Combination by eliminating such requirement set forth in paragraph D of Article Sixth of the Charter; and (c) to permit prior to a Business Combination the issuance of Common Stock or securities convertible into Common Stock or the issuance of securities which vote as a class with the Common Stock on a Business Combination by eliminating the restrictions on such issuances set forth in paragraph G of Article Sixth of the Charter.

In connection with the stockholders' vote at the annual meeting of stockholders held by the Company on August 21, 2023, 9,653 shares were tendered for redemption for a total of $101,373.

On October 23, 2023 the Company received approval (the "Approval") from the Nasdaq Listing Qualifications Department of the Nasdaq that the Company's application to transfer the listing of its Common Stock, units and rights from the Global Market to the Capital Market has been approved. The Common Stock, units and rights will be transferred to the Capital Market at the opening of business on October 27, 2023. Common stock, units and rights will continue to trade under the symbols "MCAG," "MCAGU" and "MCAGR," respectively and trading of its Common Stock, units and rights will be unaffected by this transfer. The Capital Market operates in substantially the same manner as the Global Market, and listed companies must meet certain financial requirements and comply with Nasdaq's corporate governance requirements.

As previously disclosed, the Company received three letters from Nasdaq indicating the Company failed to comply with certain continued listing requirements for the Global Market, specifically on: (i) April 3, 2023, the Company received a letter from Nasdaq stating that the Company's listed securities failed to comply with the $50,000,000 market value of listed securities ("MVLS") requirement for continued listing on the Global Market in accordance with Nasdaq Listing Rule 5450(b)(2)(A) based upon the Company's MVLS for the 30 consecutive business days prior to the date of the notice, (ii) May 18, 2023, the Company received a letter from Nasdaq stating that the Company failed to maintain the minimum 1,100,000 publicly held shares as required by the Nasdaq continued listing rules, and (iii) June 27, 2023, the Company received a letter from Nasdaq stating that the Company's publicly held shares failed to maintain a minimum Market Value of Publicly Held Shares ("MVPHS") of $15,000,000 which is a requirement for continued listing on the Global Market in accordance with Nasdaq Listing Rule 5450(b)(3)(C) based upon the Company's MVPHS for the 30 consecutive business days prior to the date of the notice. Upon the transfer of the listing of the Company's securities to the Capital Market on October 27, 2023, each of the above deficiencies will be resolved because the Company will no longer be subject to the continued listing requirements for the Global Market.

On October 25, 2023, the Company issued a press release announcing its listing transfer to the Capital Market.

On November 9, 2023, the Company received a notice from Nasdaq stating that the staff determined that the Company met all the continued listing standards to phase down, including the $35,000,000 MVLS standard for the Capital Market. Accordingly, the Company has regained compliance with the Rule and this matter is now closed.

On December 13, 2023, the Company received a notice from the Nasdaq Stock Market LLC ("Nasdaq"), stating that the Company's listed securities failed to comply with the $35,000,000 market value of listed securities ("MVLS") requirement for continued listing on The Nasdaq Capital Market in accordance with Nasdaq Listing Rule 5550(b)(2) based upon the Company's MVLS for the 30 consecutive business days prior to the date of the Notice.

The Notice has no immediate effect on the listing of the Company's securities on Nasdaq and in accordance with Nasdaq Listing Rule 5810(c)(3)(C), the Company has been provided a period of 180 calendar days, or until June 10, 2024, in which to regain compliance. In order to regain compliance, the MVLS of the Company must close at $35,000,000 or more for a minimum of ten consecutive business days during this 180-day period. On June 5, 2024, the Company received a notification letter from Nasdaq stating that for the last 10 consecutive business days, from May 21, 2024 to June 4, 2024, the Company's MVLS has been $35,000,000 or greater. Accordingly, the Company has regained compliance with the MVLS Rule and this matter is now closed.

On each of November 15, 2023, February 16, 2024, May 15, 2024 and August 15, 2024 the Company deposited $51,932 to the Trust Account on each date, ultimately extending the Combination Period from November 16, 2023 to November 16, 2024.

On July 18, 2024, the Company received a notice (the "Notice") from The Nasdaq Stock Market LLC ("Nasdaq") notifying the Company that, because the Company is delinquent in filing its Form 10-K for the year ended December 31, 2023 and Form 10-Q for the quarter ended March 31, 2024, the Company no longer complies with Nasdaq Listing Rule 5250(c)(1) (the "Listing Rule"), which requires companies with securities listed on Nasdaq to timely file all required periodic reports with the SEC. The Notice has no immediate effect on the listing or trading of the Company's common stock, units or rights on the Nasdaq Capital Market. In accordance with Nasdaq's listing rules, the Company has 60 calendar days, or until September 2, 2024, after the Notice to submit a plan of compliance (the "Plan") to Nasdaq addressing how the Company intends to regain compliance with Nasdaq's listing rules, and Nasdaq has the discretion to grant the Company up to 180 calendar days from the due date of the Form 10-K, or October 14, 2024, to regain compliance.

On September 11, 2024, the Company received a letter from Nasdaq that stated based on the August 26, 2024 filing of the Company's Form 10-K for the year ended December 31, 2023, the Staff has determined the Company complies with the Listing Rule and that the matter is now closed.

On September 13, 2024, the Company filed the March 31, 2024 10-Q with the SEC. Then on September 16, 2024, the Company submitted a letter to Nasdaq setting forth the Company's plan to regain compliance with the Listing Rule. The Company also requested the Staff to provide an exception, to October 14, 2024, to allow the Company to regain compliance with the Listing Rule.

On October 4, 2024, the Company filed the June 30, 2024 10-Q with the SEC. On October 30, 2024, the Company received a letter from Nasdaq stating that the Company had regained compliance with the Listing Rule and that the matter is now closed.

On November 8, 2024, the Company held an annual meeting of stockholders (the "Annual Meeting"), in which the stockholders approved Amendment No. 4 to the Company's Amended and Restated Certificate of Incorporation (the "Charter"). This amendment extends the deadline for completing an initial business combination to November 16, 2025. In connection with the Annual Meeting, 418,217 shares of the Company's publicly traded common stock were tendered for redemption for a total of $4,736,743.

The Company received a notice, dated November 14, 2024 (the "Notice") from the Nasdaq stating that the Company did not comply with Nasdaq Interpretive Material IM-5101-2, and that its securities are now subject to delisting. The Company's registration statement, filed in connection with the Company's IPO, became effective on November 12, 2021. Pursuant to IM-5101-2, the Company, a special purpose acquisition company, must complete one or more business combinations within 36 months of the effectiveness of its IPO registration statement. Since the Company did not complete its initial business combination by November 12, 2024, the Company did not comply with IM-5101-2, and its securities are now delisted. The Company did not appeal Nasdaq's determination to delist the Company securities and accordingly, the Company's securities was suspended from trading on Nasdaq at the opening of business on November 21, 2024. However, the Company commenced trading its securities on the over-the-counter market on November 21, 2024.

On April 11, 2025, the Company filed a Form 25-NSE with the Securities and Exchange Commission, which removed the Company's securities from listing and registration on the Nasdaq Stock Market.

Following the suspension of trading on The Nasdaq Capital Market, the Company's Units, shares of Class A common stock and redeemable warrants are eligible to trade on the OTC Pink Marketplace under the symbols "MCAG", "MCAGR" and "MCAGU " respectively. On November 21, 2024, Nasdaq completed the delisting by filing a Notification of Removal from Listing and/or Registration under Section 12(b) of the Securities and Exchange Act of 1934, as amended, on Form 25 with the U.S. Securities and Exchange Commission.

Notwithstanding the delisting of the Company's securities from Nasdaq, it remains the intention of the Company to continue to pursue a business combination.

If the Company is unable to complete a Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned on the funds held in the Trust Account and not previously released to the Company to pay taxes, divided by the number of then outstanding Public Shares, which redemption will completely extinguish public stockholders' rights as stockholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company's remaining stockholders and the Company's board of directors, dissolve and liquidate, subject in the case of clauses (ii) and (iii) to the Company's obligations under Delaware law to provide for claims of creditors and the requirements of other applicable law.

The Sponsor has agreed to waive its liquidation rights with respect to the Private Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Sponsor or any of its respective affiliates acquire Public Shares after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period 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 Unit ($10.00).

In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a vendor for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amounts in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less taxes payable, provided that such liability will not apply to any claims by a third party who executed a waiver of any and all rights to the monies held in the Trust Account nor will it apply to any claims under the Company's indemnity of the underwriters of Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the "Securities Act"). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers, 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.

***Risks and Uncertainties***

Management continues to evaluate the impact of the COVID-19 pandemic and has concluded that while it is reasonably possible that the virus could have a negative effect on the Company's financial position, results of its operations, and/or search for a target company, the specific impact is not readily determinable as of the date of these financial statements. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

In February 2022, the Russian Federation and Belarus commenced a military action with the country of Ukraine. As a result of this action, various nations, including the United States, have instituted economic sanctions against the Russian Federation and Belarus. Separately, in October 2023, Israel and certain Iranian-backed Palestinian forces began an armed conflict in Israel, the Gaza Strip, and surrounding areas, which threatens to spread to other Middle Eastern countries including Lebanon and Iran. The impact of these conflicts and related sanctions on the world economy are not determinable as of the date of these financial statements. The specific impact on the Company's financial condition, results of operations, and cash flows is also not determinable as of the date of these financial statements.

On August 16, 2022, the Inflation Reduction Act of 2022 (the "IR Act") was signed into federal law. The IR Act provides for, among other things, a new U.S. federal 1% excise tax on certain repurchases (including redemptions) of stock by publicly traded domestic (i.e., U.S.) corporations and certain domestic subsidiaries of publicly traded foreign corporations. The excise tax is imposed on the repurchasing corporation itself, not its shareholders from which shares are repurchased. The amount of the excise tax is generally 1% of the fair market value of the shares repurchased at the time of the repurchase. However, for purposes of calculating the excise tax, repurchasing corporations are permitted to net the fair market value of certain new stock issuances against the fair market value of stock repurchases during the same taxable year. In addition, certain exceptions apply to the excise tax. The U.S. Department of the Treasury (the "Treasury") has been given authority to provide regulations and other guidance to carry out and prevent the abuse or avoidance of the excise tax. The IR Act applies only to repurchases that occur after December 31, 2022.

Any redemption or other repurchase that occurs after December 31, 2022, in connection with a Business Combination, extension vote or otherwise, may be subject to the excise tax. Whether and to what extent the Company would be subject to the excise tax in connection with a Business Combination, extension vote or otherwise would depend on a number of factors, including (i) the fair market value of the redemptions and repurchases in connection with the Business Combination, extension or otherwise, (ii) the structure of a Business Combination, (iii) the nature and amount of any "PIPE" or other equity issuances in connection with a Business Combination (or otherwise issued not in connection with a Business Combination but issued within the same taxable year of a Business Combination) and (iv) the content of regulations and other guidance from the Treasury. In addition, because the excise tax would be payable by the Company and not by the redeeming holder, the mechanics of any required payment of the excise tax have not been determined. The foregoing could cause a reduction in the cash available on hand to complete a Business Combination and in the Company's ability to complete a Business Combination.

During the second quarter of 2024, the Internal Revenue Service issued final regulations with respect to the timing and payment of the excise tax. These regulations provided that the filing and payment deadline for any liability incurred during the period from January 1, 2023 to December 31, 2023 would be October 31, 2024. The Company is currently evaluating its options with respect to this obligation. Any amount of such excise tax not paid in full, will be subject to additional interest and penalties which are currently estimated at 10% interest per annum and a 5% underpayment penalty per month or portion of a month up to 25% of the total liability for any amount that is unpaid from November 1, 2024 until paid in full. As of the date of filing of these financial statements, the Company has not filed an excise tax return for the year ended December 31, 2023 and 2024 nor paid the amount due. The Company recognized a total of $9,663 and $14,765 in interest and penalties for the three and six months ended June 30, 2025, respectively.

On May 12, 2023, the Company's stockholders elected to redeem 1,405,134 shares for a total of $14,591,037. On August 21, 2023, the Company's stockholders elected to redeem 9,653 shares for a total of $101,372. On November 8, 2024, the Company's stockholders elected to redeem 418,217 shares for a total of $4,736,743. The Company evaluated the classification and accounting of the share/ stock redemption under ASC 450, "Contingencies". ASC 450 states that when a loss contingency exists the likelihood that the future event(s) will confirm the loss or impairment of an asset or the incurrence of a liability can range from probable to remote. A contingent liability must be reviewed at each reporting period to determine appropriate treatment. The Company evaluated the current status and probability of completing a Business Combination as of June 30, 2025 and concluded that it is probable that a contingent liability should be recorded. As of June 30, 2025 and December 31, 2024, the Company recorded $212,457 (inclusive of $14,765 interest and penalties for the six months ended June 30, 2025) and $197,692 (inclusive of $3,401 interest and penalties for the year ended December 31, 2024), respectively, of excise tax liability calculated as 1% of the shares redeemed. The Company recognized a total of $18,166 in interest and penalties through June 30, 2025.

***Going Concern***

In connection with the Company's assessment of going concern considerations in accordance with Financial Accounting Standard Board ("FASB") Accounting Standards Update ("ASU") 2014-15, "Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern," the Company has until November 16, 2025 to consummate the proposed Business Combination, provided that the Company deposits into the Trust Account an amount equal to $0.10 per outstanding Public Share for each three-month extension commencing on November 17, 2023. It is uncertain that the Company will be able to consummate the proposed Business Combination by this time. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the liquidity condition and mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution, raises substantial doubt about the Company's ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after November 16, 2025. The Company intends to complete the proposed Business Combination before the mandatory liquidation date. However, there can be no assurance that the Company will be able to consummate any Business Combination by November 16, 2025.

***Liquidity and Capital Resources***

As of June 30, 2025, the Company had $25,321 of cash held outside its Trust Account for use as working capital (the "Working Capital").

In addition, in order to finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor or certain of the Company's officers and directors may, but are not obligated to, provide the Company working capital loans, as defined below (see Note 5). To date, there were no amounts outstanding under any working capital loans.

The Company will need to raise additional capital through loans or additional investments from its Sponsor, stockholders, officers, directors, or third parties. The Company's officers, directors and Sponsor may, but are not obligated to, loan the Company funds, from time to time or at any time, in whatever amount they deem reasonable in their sole discretion, to meet the Company's working capital needs. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

On February 15, 2023, the Company issued a non-interest bearing, unsecured promissory note in the aggregate principal amount of $300,000 (the "Note") to the Sponsor. Pursuant to the Note, the Sponsor loaned the Company an aggregate amount of $300,000 that is due and payable upon the Company's consummation of an initial Business Combination with a target business. The Note will either be paid upon consummation of the Company's initial Business Combination, or, at the Sponsor's discretion, converted upon consummation of the Company's Business Combination into private units at a price of $10.00 per unit. The loan will be forgiven, except to the extent of any funds held outside of the trust account, by the Sponsor or its affiliates if the Company is unable to consummate an initial Business Combination during the Combination Period.

On March 31, 2023, the Company and UHY Advisors/UHY LLP, the Company's previous independent registered public accounting firm, entered into an unsecured promissory note for services rendered and unpaid in the principal sum of one hundred eight thousand one dollars and ninety cents ($108,001), plus interest applied monthly on any un-paid balance at the rate of eight (8%) percent per year until such sum is fully paid. On August 21, 2023, the Company and UHY Advisors/UHY LLP extended the due date of promissory note to October 31, 2023. If $102,877 is paid in full on this promissory note no later than October 31, 2023, all accrued finance charges on this promissory note will be forgiven. The promissory note is payable by the Company in advance without penalty. $5,125 of the balance was waived by UHY LLP. On November 6, 2023, the Company and UHY Advisors/UHY LLP further amended the promissory note by reducing the unpaid principal sum to $58,001 and extending the due date of the promissory note to January 31, 2024. On May 22, 2024, UHY Advisors/UHY LLP has agreed to extinguish a total of $179,035 of liabilities to UHY Advisors/UHY LLP and all interest accrued of $6,989 for a settlement amount of $160,000. As of June 30, 2025, there were no longer outstanding balance and accrued interest payable under this note in the accompanying balance sheets.

On May 16, 2023, the Company and the Sponsor entered into an amendment to the Note, pursuant to which the Note and the forgiveness term was extended from May 16, 2023 to November 16, 2024. On September 13, 2023, as approved by the Company's audit committee, the Company entered into a note conversion agreement (the "Note Conversion Agreement") with the Sponsor, to convert the Note into 75,000 shares of the Company's Common Stock. Accordingly, the Company satisfied the Note in exchange for the issuance of 75,000 shares of Common Stock (Note 7).

On October 30, 2023, the Company issued an unsecured promissory note in the aggregate principal amount up to $400,000 (the "2023 Note") to the Company's Sponsor. Pursuant to the 2023 Note, the Sponsor agreed to loan to the Company an aggregate amount up to $400,000 that may be drawn down by the Company from time to time by written notice to the Sponsor. The aggregate amount advanced under the 2023 Note is due payable by the Company on the earlier of: (i) the date on which Company consummates an initial Business Combination with a target business, or (ii) the date the Company liquidates if a Business Combination is not consummated. The 2023 Note does not bear interest. In the event that the Company does not consummate a Business Combination, the 2023 Note will be repaid only from amounts remaining outside of the Company's trust account, if any. The proceeds of the 2023 Note will be used by the Company for working capital purposes.

On April 3, 2024, the Company issued an unsecured promissory note in the aggregate principal amount up to $300,000 (the "2024 Note" and together with the 2023 Note, the "Notes") to the Sponsor. Pursuant to the 2024 Note, the Sponsor agreed to loan to the Company an aggregate amount up to $300,000 that may be drawn down by the Company from time to time by written notice to the Sponsor. The aggregate amount advanced under the 2024 Note is due payable by the Company on the earlier of: (i) the date on which Company consummates an initial business combination with a target business, or (ii) the date the Company liquidates if a business combination is not consummated. The 2024 Note does not bear interest.

***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 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.

***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 independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, 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 stockholder 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 financial statements in conformity with U.S. 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 financial statements and the reported amounts of expenses during the reporting period. Actual results could differ from those estimates.

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 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. At June 30, 2025 and December 31, 2024, the Company had no cash equivalents.

***Investments Held in Trust Account***

The Company's portfolio of investments held in the Trust Account is comprised of investments in money market funds and generally have a readily determinable fair value, or a combination thereof. Gains and losses resulting from the change in fair value of these securities are included in interest earned on investments held in the Trust Account in the accompanying statements of operations. The estimated fair values of investments held in the Trust Account are determined using available market information.

Interest income earned on these investments is fully reinvested into the Investments held in the Trust Account and therefore considered as an adjustment to reconcile net profit/(loss) to net cash used in operating activities in the Statements of Cash Flows. Such interest income reinvested will be used to redeem all or a portion of the ordinary shares upon the completion of Business Combination.

***Common Stock Subject to Possible Redemption***

The Company accounts for its Common Stock subject to possible redemption in accordance with the guidance in FASB Accounting Standards Codification ("ASC") Topic 480 "Distinguishing Liabilities from Equity." Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable Common Stock (including Common Stock that features redemption rights that is either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within the Company's control) is classified as temporary equity. At all other times, Common Stock is classified as stockholders' equity. The Company's Common Stock features certain redemption rights that are considered to be outside of the Company's control and subject to occurrence of uncertain future events.

In connection with the stockholders' vote at the special meetings of stockholders held by the Company on December 20, 2022, May 12, 2023, August 21, 2023 and November 8, 2024, 4,965,892, 1,405,134, 9,653 and 418,217 shares of Common Stock were tendered for redemption, respectively.

The Company recognizes changes in redemption value immediately as they occur and adjusts the carrying value of redeemable Class A common stock to equal the redemption value at the end of each reporting period. This method would view the end of the reporting period as if it were also the redemption date for the security. Such changes are reflected in additional paid-in capital, or in the absence of additional paid-in capital, in accumulated deficit. As of June 30, 2025 and 2024, the Company recorded an accretion of $2,473 and $207,863, respectively, which is in accumulated deficit.

Accordingly, at June 30, 2025 and December 31, 2024 101,104 shares of Common Stock subject to possible redemption is presented at redemption value of $11.54 and $11.51, respectively, as temporary equity, outside of the stockholders' deficit section of the Company's balance sheets.

At June 30, 2025 and December 31, 2024, the Common Stock reflected in the balance sheets are reconciled in the following table:

---

| | |
|:---|:---|
| **Common stock subject to possible redemption, December 31, 2023** | $**5579231** |

***Offering Costs***

Offering costs consisted of legal, accounting and other expenses incurred through the Initial Public Offering that were directly related to the Initial Public Offering. Offering costs were allocated to the separable financial instruments issued in the Initial Public Offering based on a relative fair value basis, compared to total proceeds received. Offering costs associated with the Common Stock issued were initially charged to temporary equity and then accreted to Common Stock subject to redemption upon the completion of the Initial Public Offering. Offering costs amounted to $5,090,361 consisting of $1,380,000 of underwriting fees, $2,070,000 of deferred underwriting fees and $1,640,361 of other offering costs. These were charged to stockholders' deficit upon the completion of the Initial Public Offering. $4,657,681 was allocated to Public Shares and charged to temporary equity, and $432,681 was allocated to public rights and charged to stockholders' deficit.

***Income Taxes***

The Company accounts for income taxes under ASC 740, "Income Taxes." ASC 740, Income Taxes, requires the recognition of deferred tax assets and liabilities for both the expected impact of differences between the financial statements and tax basis of assets and liabilities and for the expected future tax benefit to be derived from tax loss and tax credit carry forwards. 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. As of June 30, 2025 and December 31, 2024, the Company's deferred tax asset had a full valuation allowance recorded against it.

ASC 740-270-25-2 requires that an annual effective tax rate be determined and such annual effective rate applied to year to date income in interim periods under ASC 740-270-30-5. The Company's effective tax rate was (2.12%) and 146.92% for the three months ended June 30, 2025 and 2024, respectively, and (1.59%) and 138.04% for the six months ended June 30, 2025 and 2024, respectively. The effective tax rate differs from the statutory tax rate of 21% for the period ended June 30, 2025 and 2024, due to change in valuation allowance and interest and penalties.

ASC 740 also clarifies the accounting for uncertainty in income taxes recognized in an enterprise's financial statements and prescribes a recognition threshold and measurement process for financial statement recognition and measurement of a tax position 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. ASC 740 also provides guidance on derecognition, classification, interest and penalties, accounting in interim period, disclosure and transition.

The Company recognizes accrued interest and penalties related to income taxes and unrecognized tax benefits as income tax expense. There were no unrecognized tax benefits as of June 30, 2025 and December 31, 2024. Amounts accrued for interest and penalties were $14,471 and $51,813, respectively as of June 30, 2025 and December 31, 2024. 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 has identified the United States as its only "major" tax jurisdiction. The Company is subject to income taxation by major taxing authorities since inception. These examinations may include questioning the timing and amount of deductions, the nexus of income among various tax jurisdictions and compliance with federal and state tax laws. The Company's management does not expect that the total amount of unrecognized tax benefits will materially change over the next twelve months.

***Net Loss per Common Share***

The Company complies with accounting and disclosure requirements of FASB ASC 260, Earnings Per Share. The statement of operations includes a presentation of loss per redeemable public share and loss per non-redeemable share following the two-class method of loss per share. In order to determine the net loss attributable to both the public redeemable shares and non-redeemable shares, the Company first considered the total loss allocable to both sets of shares. This is calculated using the total net loss less any dividends paid. For purposes of calculating net loss per share, any remeasurement of the accretion to redemption value of the redeemable shares subject to possible redemption was considered to be dividends paid to the public stockholders. Subsequent to calculating the total loss allocable to both sets of shares, the Company split the amount to be allocated using a ratio of 3% for the redeemable Public Shares and 97% for the non-redeemable shares for the period ended June 30, 2025 and 16% for the redeemable Public Shares and 84% for the non-redeemable shares for the period ended June 30, 2024, reflective of the respective participation rights.

As of June 30, 2025 and December 31, 2024, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common shares and then share in the Company's earnings. As a result, diluted loss per share is the same as basic loss per share for the periods presented.

***Concentration of Credit Risk***

Financial instruments that potentially subject the Company to concentrations of credit risk consist of cash accounts in a financial institution, which, at times, may exceed the Federal Depository Insurance Coverage of $250,000. At June 30, 2025 and December 31, 2024, the Company has not experienced losses on these accounts and management believes the Company is not exposed to significant risks on such accounts.

***Fair Value of Financial Instruments***

The fair value of the Company's assets and liabilities approximates the carrying amounts represented in the balance sheets, primarily due to their short-term nature.

***Recent Accounting Pronouncements***

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires disclosure of incremental income tax information within the rate reconciliation and expanded disclosures of income taxes paid, among other disclosure requirements. ASU 2023-09 is effective for public business entities for fiscal years beginning after December 15, 2024 and for all other entities after December 15, 2025. Early adoption is permitted. Since the Company elected not to opt out of the extended transition period offered to emerging growth companies, which defers adoption of new or revised financial accounting standards until private companies are required to comply, the Company will adopt ASU 2023-09 for the fiscal year beginning after December 15, 2025. The Company does not expect the adoption to have a material impact on the accompanying financial statements and disclosures.

In November 2024, the FASB issued ASU 2024-03 and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220-40): Disaggregation of Income Statement Expenses (ASU 2025-01). The guidance requires disclosures about specific expense categories, including but not limited to, purchases of inventory, employee compensation, depreciation, amortization and selling expenses. The ASU is effective in the first annual reporting period beginning after December 15, 2026, and for interim periods within annual reporting periods beginning after December 15, 2027. The Company's management is currently assessing the effect that adoption of this guidance will have on its financial statements and disclosures.

The Company's 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 financial statements.

**NOTE 3. INITIAL PUBLIC OFFERING**

Pursuant to the Initial Public Offering, the Company sold 6,000,000 Units, at a purchase price of $10.00 per Unit. Each Unit consisted of one share of Common Stock and one right ("Public Right"). Each Public Right entitled the holder to receive one-tenth of one share of Common Stock at the closing of a Business Combination (see Note 7). On November 18, 2021, the underwriters fully exercised their over-allotment option, resulting in an additional 900,000 Units issued for an aggregate amount of $9,000,000.

In connection with the stockholders' vote at the special meetings of stockholders held by the Company on December 20, 2022, May 12, 2023, August 21, 2023 and November 8, 2024, 4,965,892, 1,405,134, 9,653 and 418,217 shares of Common Stock were tendered for redemption, respectively.

**NOTE 4. PRIVATE PLACEMENT**

Simultaneously with the closing of the Initial Public Offering, on November 16, 2021, the Sponsor purchased an aggregate of 205,000 Private Units at a price of $10.00 per Private Unit, for an aggregate purchase price of $2,050,000, in a private placement. In connection with the underwriters' full exercise of their over-allotment option, on November 18, 2021, the Company also consummated the sale of an additional 18,000 Private Units at $10.00 per Private Unit, generating total proceeds of $180,000. Each Private Unit consists of one share of Common Stock ("Private Share") and one right ("Private Right"). Each Private Right entitles the holder to receive one-tenth of one share of Common Stock at the closing of a Business Combination. The proceeds from the Private Units were be 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 Units will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law), and the Private Units and all underlying securities will expire worthless.

**NOTE 5. RELATED PARTY TRANSACTIONS**

***Founder Shares***

On April 8, 2021, the Company issued 1,437,500 shares of Common Stock (the "Insider Shares") to the Sponsor for an aggregate purchase price of $25,000. The 1,437,500 Insider Shares include an aggregate of up to 187,500 shares subject to forfeiture by the Sponsor to the extent that the underwriters' over-allotment is not exercised in full or in part, so that the Sponsor will collectively own 20% of the Company's issued and outstanding shares after the Initial Public Offering (assuming the Sponsor does not purchase any Public Shares in the Initial Public Offering and excluding the Private Shares). In connection with the increase in the size of the offering, on November 2, 2021, the company declared a 20% stock dividend on each insider share thereby increasing the number of issued and outstanding Insider Shares to 1,725,000, including up to an aggregate of 225,000 shares of Common Stock subject to forfeiture by our insiders to the extent that the underwriters' over-allotment option is not exercised in full or in part. The stock dividend was considered in substance a recapitalization transaction, which was recorded and presented retroactively. As a result of the underwriters' election to fully exercise their over-allotment option on November 18, 2021, no Insider Shares are currently subject to forfeiture.

***Administrative Support Agreement***

The Company agreed, commencing on November 12, 2021, to pay the Sponsor, affiliates, or advisors a total of up to $10,000 per month for office space, utilities, out of pocket expenses, and secretarial and administrative support. The arrangement will terminate upon the earlier of the Company's consummation of a Business Combination or its liquidation. For the three and six months ended June 30, 2025 and 2024, the Company incurred and paid $30,000 and $60,000 in fees for these services, respectively.

***Promissory Notes — Related Parties***

On April 9, 2021, the Sponsor agreed to loan the Company an aggregate of up to $500,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the "Note"). This Note was non-interest bearing and payable on the completion of the closing of the Initial Public Offering. The Note was paid in full on November 16, 2021. The Company can no longer borrow against this note.

On October 30, 2023, the Company issued an unsecured promissory note in the aggregate principal amount up to $400,000 (the "2023 Note") to the Company's Sponsor. Pursuant to the 2023 Note, the Sponsor agreed to loan to the Company an aggregate amount up to $400,000 that may be drawn down by the Company from time to time by written notice to the Sponsor. The aggregate amount advanced under the 2023 Note is due payable by the Company on the earlier of: (i) the date on which Company consummates an initial Business Combination with a target business, or (ii) the date the Company liquidates if a Business Combination is not consummated. The 2023 Note does not bear interest. In the event that the Company does not consummate a Business Combination, the 2023 Note will be repaid only from amounts remaining outside of the Company's trust account, if any. The proceeds of the 2023 Note will be used by the Company for working capital purposes.

***Related Party Loans***

In order to finance transaction costs in connection with a Business Combination, the Sponsor, an affiliate of the Sponsor, or the Company's officers and directors may, but are not obligated to, loan the Company funds from time to time or at any time, as may be required ("Working Capital Loans"). Each Working Capital Loan would be evidenced by a promissory note. The Working Capital Loans would either be paid upon consummation of a Business Combination, without interest, or, at the holder's discretion, up to $1,500,000 of the Working Capital Loans may be converted into Private Units at a price of $10.00 per unit. The Private Units would be identical to the Private Units. In the event that a Business Combination does not close, the Company may use a portion of the proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held In the Trust Account would be used to repay the Working Capital Loans.

On February 15, 2023, the Company issued a non-interest bearing, unsecured promissory note in the aggregate principal amount of $300,000 (the "Note") to the Sponsor. Pursuant to the Note, the Sponsor loaned the Company an aggregate amount of $300,000 that is due and payable upon the Company's consummation of an initial Business Combination with a target business. The Note will either be paid upon consummation of the Company's initial Business Combination, or, at the Sponsor's discretion, converted upon consummation of the Company's Business Combination into private units at a price of $10.00 per unit. The loan will be forgiven, except to the extent of any funds held outside of the trust account, by the Sponsor or its affiliates if the Company is unable to consummate an initial Business Combination during the Combination Period. On May 16, 2023, the Company and the Sponsor entered into an amendment to the Note, pursuant to which the Note and the forgiveness term was extended from May 16, 2023 to November 16, 2025.

On September 13, 2023, as approved by the Company's audit committee, the Company entered into the Note Conversion Agreement with the Sponsor, to convert the Note into 75,000 shares of the Company's Common Stock. Accordingly, the Company satisfied the Note in exchange for the issuance of 75,000 shares of Common Stock (Note 6).

As of June 30, 2025 and December 31, 2024, there were no outstanding amounts under the Note issued on February 15, 2023.

The Company paid legal counsel a retainer of $25,000 upon filing the registration statement and $100,000 upon the closing of the Initial Public Offering and agreed to pay $50,000 upon closing of a Business Combination.

**(Unaudited)**

The underwriters are entitled to a deferred fee of $0.30 per unit, or $2,070,000 in the aggregate will be payable to the underwriters for deferred underwriting commissions. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

***Representative Shares***

The Company issued to the underwriter and/or its designees 177,900 shares of Common Stock (the "Representative Shares"). The Company accounted for the Representative Shares as an expense of the Initial Public Offering, resulting in a charge directly to stockholder's equity. The Company estimates the fair value of Representative Shares to be $1,383,617 based upon the offering price of the shares of $7.78 per share. The Representative Shares have been deemed compensation by FINRA and are therefore subject to a lock-up for a period of 180 days immediately following the effective date of the registration statement related to the Initial Public Offering pursuant to Rule 5110(g)(1) of FINRA's NASD Conduct Rules. Pursuant to FINRA Rule 5110(g)(1), these securities will not be the subject of any hedging, short sale, derivative, put or call transaction that would result in the economic disposition of the securities by any person for a period of 180 days immediately following the effective date of the registration statements related to the Initial Public Offering, nor may they be sold, transferred, assigned, pledged or hypothecated for a period of 180 days immediately following the effective date of the registration statements related to the Initial Public Offering except to any underwriter and selected dealer participating in the Initial Public Offering and their bona fide officers or partners.

At or immediately before the closing of the Business Combination, by virtue of the Share Swap, the right to each CUBEBIO Common Share held by Swapping Shareholders shall be converted into and shall for all purposes represent only the right to receive a number of validly issued, fully paid and non-assessable PubCo Ordinary Shares equal to the CUBEBIO Exchange Ratio, which shall be an amount obtained by dividing (i) the number of PubCo Ordinary Shares equal to the quotient of the $375,000,000 divided by $10.00 by (ii) the aggregate number of CUBEBIO Common Shares, the number of CUBEBIO Common Shares subject to such CUBEBIO Options and the number of CUBEBIO Common Shares subject to such CUBEBIO Warrants outstanding immediately prior to the Merger Effective Time.

***Vendor Liability and Note Conversion Agreement***

On September 13, 2023, the Company entered into four separate vendor liability conversion agreements (the "Vendor Liability Conversion Agreements") with four of the Company's vendors. Pursuant to the Vendor Liability Conversion Agreements, an aggregate of $1,800,000 of the service fees due to the vendors have been converted into an aggregate of 450,000 shares Company's Common Stock based upon a conversion price of $4.00 per share. Accordingly, the Company satisfied aggregate vendor liabilities of $1,800,000 in exchange for the issuance of 450,000 shares of Common Stock. The Company determined the $4.00 per share approximates the fair value of the Common Stock as the shares being issued are restricted as such no gain or loss was recognized on settlement of the liability.

On February 15, 2023, the Company issued a non-interest bearing, unsecured promissory note in the aggregate principal amount of $300,000 (the "Note") to the Sponsor. Pursuant to the Note, the Sponsor loaned the Company an aggregate amount of $300,000 that is due and payable upon the Company's consummation of an initial Business Combination with a target business. The Note would either be paid upon consummation of the Company's initial Business Combination, or, at the Sponsor's discretion, converted into private units at a price of $10.00 per unit. On September 13, 2023, as approved by the Company's audit committee, the Company entered into the Note Conversion Agreement with the Sponsor, to convert the Note into 75,000 shares of the Company's Common Stock. Accordingly, the Company satisfied the Note in exchange for the issuance of 75,000 shares of Common Stock. The Company determined the $4.00 per share approximates the fair value of the Common Stock as the shares being issued are restricted as such no gain or loss was recognized on settlement of the liability.

Pursuant to the Vendor Liability Conversion Agreements and the Note Conversion Agreement, the vendors and the Sponsor have (i) one demand registration of the sale of such shares at the Company's expense, and (ii) unlimited "piggyback" registration rights, both for a period of five (5) years after the closing of the Company's initial Business Combination at the Company's expense.

On October 30, 2023, the Company issued an unsecured promissory note in the aggregate principal amount up to $400,000 (the "2023 Note") to the Company's Sponsor. Pursuant to the 2023 Note, the Sponsor agreed to loan to the Company an aggregate amount up to $400,000 that may be drawn down by the Company from time to time by written notice to the Sponsor. On April 3, 2024, the Company issued an unsecured promissory note in the aggregate principal amount up to $300,000 (the "2024 Note" and together with the 2023 Note, the "Notes") to the Sponsor. Pursuant to the 2024 Note, the Sponsor agreed to loan to the Company an aggregate amount up to $300,000 that may be drawn down by the Company from time to time by written notice to the Sponsor. Collectively the principal amount outstanding under the Notes was $600,000 (the "Principal Amount due under the Notes")

On April 19, 2024, as approved by the Company's audit committee, the Company entered into a note conversion agreement (the "Note Conversion Agreement") with the Sponsor, to convert the Principal Amount due under the Notes into 150,000 shares of the Company's common stock, par value $0.0001 per share (the "Common Stock"). Accordingly, the Company satisfied the Notes in exchange for the issuance of 150,000 shares of Common Stock. Pursuant to the Note Conversion Agreement, the Sponsor has (i) one demand registration of the sale of such shares at the Company's expense, and (ii) unlimited "piggyback" registration rights, both for a period of five (5) years after the closing of the Company's initial business combination at the Company's expense. The most significant assumptions used in the fair value estimate was the probability of a business combination of 38% applied to the Company's trading stock price.

On April 20, 2024, an aggregate of 150,000 shares of the Company's Common Stock has been issued pursuant to the Note Conversion Agreement, in full payment and satisfaction of the Notes in the principal amount of $600,000. The Company has relied upon Sections 4(a)(2) and/or Regulation D of the Securities Act of 1933, as amended, in connection with the conversion, as the shares were issued to sophisticated investors without a view to distribution, and were not issued through any general solicitation or advertisement. The Company determined the $4.00 per share approximates the fair value of the Common Stock as the shares being issued are restricted as such no gain or loss was recognized on settlement of the liability.

**NOTE 7. STOCKHOLDERS' DEFICIT**

***Common Stock***

The Company is authorized to issue 30,000,000 shares of Common Stock with a par value of $0.0001 per share. At May 27, 2021, there were 1,437,500 shares of Common Stock issued and outstanding, of which up to an aggregate of 187,500 shares are subject to forfeiture to the extent that the underwriters' over-allotment option is not exercised in full so that the Sponsor will own 20% of the issued and outstanding shares after the Initial Public Offering (assuming the Sponsor does not purchase any Public Shares in the Initial Public Offering and excluding the Private Shares). In connection with the increase in the size of the offering, on November 2, 2021, the Company declared a 20% stock dividend on each insider share thereby increasing the number of issued and outstanding Insider Shares to 1,725,000, including up to an aggregate of 225,000 shares of Common Stock subject to forfeiture by our insiders to the extent that the underwriters' over-allotment option is not exercised in full or in part. According to ASC 260-10-55, the stock dividend was considered in substance a recapitalization transaction, which was recorded and presented retroactively.

As a result of the underwriters' election to fully exercise their over-allotment option on November 18, 2021, no Insider Shares are currently subject to forfeiture. At June 30, 2025 and December 31, 2024, there were 2,800,900 shares of Common Stock issued and outstanding, excluding 101,104 of Common Stock subject to possible redemption which are presented as temporary equity, respectively.

***Rights***

Except in cases where the Company is not the surviving company in a Business Combination, each holder of a Public Right will automatically receive one-tenth (1/10) of one share of Common Stock upon consummation of a Business Combination, even if the holder of a Public Right converted all shares held by him, her or it in connection with a Business Combination or an amendment to the Company's Charter with respect to its pre-Business Combination activities. In the event that the Company will not be the surviving company upon completion of a Business Combination, each holder of a Public Right will be required to affirmatively convert his, her or its rights in order to receive the one-tenth (1/10) of a share underlying each Public Right upon consummation of the Business Combination.

The Company will not issue fractional shares in connection with an exchange of Public Rights. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of the Delaware General Corporation Law. As a result, the holders of the Public Rights must hold rights in multiples of 10 in order to receive shares for all of the holders' rights upon closing of a 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:

Level 1: Quoted prices in active markets for identical assets or liabilities. An active market for an asset or liability is a market in which transactions for the asset or liability occur with sufficient frequency and volume to provide pricing information on an ongoing basis.

Level 2: Observable inputs other than Level 1 inputs. Examples of Level 2 inputs include quoted prices in active markets for similar assets or liabilities and quoted prices for identical assets or liabilities in markets that are not active.

Level 3: Unobservable inputs based on our assessment of the assumptions that market participants would use in pricing the asset or liability.

The Company classifies its securities in the Trust Account that are invested in funds, such as Mutual Funds or Money Market Funds, that primarily invest in U.S. Treasury and equivalent securities as Trading Securities in accordance with ASC Topic 320 "Investments–Debt and Equity Securities. Trading Securities are recorded at fair market value on the accompanying balance sheets.

At June 30, 2025, assets held in the Trust Account were comprised of $1,181,623 in a mutual fund that is invested primarily in U.S. Treasury Securities. For the period ended June 30, 2025, the Company did not withdraw any of the interest earned on the Trust Account.

At December 31, 2024, assets held in the Trust Account were comprised of $1,157,312 in a mutual fund that is invested primarily in U.S. Treasury Securities. For the period ended December 31, 2024, the Company withdrew $140,442 of the interest earned on the Trust Account to pay franchise and income taxes and $4,736,743 in connection with the redemption of shares.

**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, or group, in deciding how to allocate resources and assess performance.

The Company's chief operating decision maker has been identified as the Chief Executive Officer ("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 has one operating segment.

When evaluating the Company's performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | **For the<br> Three Months Ended <br> June 30,** | **For the<br> Three Months Ended <br> June 30,** | **For the<br> Six Months Ended**<br> **June 30,** | **For the<br> Six Months Ended**<br> **June 30,** |
|  | **2025** | **2024** | **2025** | **2024** |
| General and administrative expenses | $120471 | $145218 | $311696 | $228987 |
| Interest earned on investments held in Trust Account | $12192 | $75065 | $24311 | $148650 |

---

The key measures of segment profit or loss reviewed by our CODM are interest earned on investments held in Trust Account and general and administrative expenses. The CODM reviews interest earned on investments held in Trust Account to measure and monitor stockholder 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.

The Company evaluated subsequent events and transactions that occurred after the balance sheet date up to the date that the 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 financial statements.

**Results of Operations**

We have neither engaged in any operations nor generated any revenues to date.

Simultaneously with the closing of the Initial Public Offering, we consummated the sale of 205,000 Private Units at a price of $10.00 per Private Unit in a private placement to the Sponsor generating gross proceeds of $2,050,000.

On November 18, 2021, the underwriters fully exercised their over-allotment option, resulting in an additional 900,000 Units issued for an aggregate amount of $9,000,000. In connection with the underwriters' full exercise of their over-allotment option, the Company also consummated the sale of an additional 18,000 Private Units at $10.00 per Private Unit, generating total proceeds of $180,000. A net total of $9,000,000 was deposited into the Trust Account, bringing the aggregate proceeds held in the Trust Account to $69,000,000.

Interest income on the balance in the Trust Account may be used by us to pay taxes. During the quarter period ended June 30, 2025, we did not withdraw any of the interest earned on the Trust Account.

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 capital stock 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 June 30, 2025, we had cash of $25,321 held outside the Trust Account for general working capital purposes. 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.

In the event that the Company does not consummate a business combination, the August 2024 Note will be repaid only from amounts remaining outside of the Company's trust account, if any. As of June 30, 2025 and December 31, 2024, there was $500,000 and $390,000 outstanding amount under this August 2024 Note, respectively.

On April 25, 2025, the Company issued an unsecured promissory note in the aggregate principal amount up to $500,000 (the "April 2025 Note") to the Company's sponsor. Pursuant to the April 2025 Note, the Sponsor agreed to loan to the Company an aggregate amount up to $500,000 that may be drawn down by the Company from time to time by written notice to the Sponsor. The aggregate amount advanced under the April 2025 Note is due payable by the Company on the earlier of: (i) the date on which Company consummates an initial business combination with a target business, or (ii) the date the Company liquidates if a business combination is not consummated. The April 2025 Note does not bear interest. In the event that the Company does not consummate a business combination, the April 2025 Note will be repaid only from amounts remaining outside of the Company's trust account, if any. The proceeds of the April 2025 Note will be used by the Company for working capital purposes. As of June 30, 2025, there was $120,000 outstanding amount under this April 2025 Note with $380,000 available for withdrawal.

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.

**Going Concern**

In connection with the Company's assessment of going concern considerations in accordance with Financial Accounting Standard Board ("FASB") Accounting Standards Update ("ASU") 2014-15, "Disclosures of Uncertainties about an Entity's Ability to Continue as a Going Concern," the Company has until November 16, 2025 to consummate the proposed Business Combination, provided that the Company deposits into the Trust Account an amount equal to $0.10 per outstanding Public Share for each three-month extension commencing on November 17, 2023. It is uncertain that the Company will be able to consummate the proposed Business Combination by this time. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the liquidity condition and mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution, raises substantial doubt about the Company's ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after November 16, 2025. The Company intends to complete the proposed Business Combination before the mandatory liquidation date. However, there can be no assurance that the Company will be able to consummate any Business Combination by November 16, 2025.

**Off-Balance Sheet Financing Arrangements**

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of June 30, 2025. 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 an affiliates, or advisors a total of up to $10,000 per month for office space, utilities, out of pocket expenses, and secretarial and administrative support. The arrangement will terminate upon the earlier of the Company's consummation of a Business Combination or its liquidation.

The underwriters are entitled to a deferred fee of $0.30 per unit, or $2,070,000 in the aggregate will be payable to the underwriters for deferred underwriting commissions. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.

**Critical Accounting Policies**

The preparation of 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. We have identified the following critical accounting policies:

*Common Stock Subject to Possible Redemption*

We account for our Common Stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification ("ASC") Topic 480 "Distinguishing Liabilities from Equity." Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable Common Stock (including Common Stock that features 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) is classified as temporary equity. At all other times, Common Stock is classified as stockholders' equity. Our Common Stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, the Common Stock subject to possible redemption is presented as temporary equity, outside of the stockholders' equity section of our balance sheets.

*Net Loss per Common Share*

We comply with accounting and disclosure requirements of Financial Accounting Standards Board ("FASB") ASC 260, Earnings Per Share. The statement of operations include a presentation of loss per redeemable public share and loss per non-redeemable share following the two-class method of loss per share. In order to determine the net loss attributable to both the public redeemable shares and non-redeemable shares, we first considered the total loss allocable to both sets of shares. This is calculated using the total net loss less any dividends paid. For purposes of calculating net loss per share, any remeasurement of the accretion to redemption value of the common shares subject to possible redemption was considered to be dividends paid to our public stockholders. Subsequent to calculating the total loss allocable to both sets of shares, we split the amount to be allocated using a ratio of 3% for the Public Shares and 97% for the non-redeemable shares for the period ended June 30, 2025 and 16% for the redeemable Public Shares and 84% for the non-redeemable shares for the period ended June 30, 2024, reflective of the respective participation rights.

As of June 30, 2025, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common shares and then share in our earnings. As a result, diluted loss per share is the same as basic loss per share for the periods presented.

*Recent Accounting Pronouncements*

In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires disclosure of incremental income tax information within the rate reconciliation and expanded disclosures of income taxes paid, among other disclosure requirements. ASU 2023-09 is effective for public business entities for fiscal years beginning after December 15, 2024 and for all other entities after December 15, 2025. Early adoption is permitted. Since the Company elected not to opt out of the extended transition period offered to emerging growth companies, which defers adoption of new or revised financial accounting standards until private companies are required to comply, the Company will adopt ASU 2023-09 for the fiscal year beginning after December 15, 2025. The Company does not expect the adoption to have a material impact on the accompanying financial statements and disclosures.

In November 2024, the FASB issued ASU 2024-03 and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220-40): Disaggregation of Income Statement Expenses (ASU 2025-01). The guidance requires disclosures about specific expense categories, including but not limited to, purchases of inventory, employee compensation, depreciation, amortization and selling expenses. The ASU is effective in the first annual reporting period beginning after December 15, 2026, and for interim periods within annual reporting periods beginning after December 15, 2027. The Company's management is currently assessing the effect that adoption of this guidance will have on its financial statements and disclosures.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our financial statements.

**Item 3. Quantitative and Qualitative Disclosures About Market Risk**

Not required for smaller reporting companies.

**Item 4. Controls and Procedures**

Disclosure controls and procedures are controls and other procedures that are 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 our management, including Dr. Suying Liu, our Chief Executive Officer and Chief Financial Officer, to allow timely decisions regarding required disclosure.

*Evaluation of Disclosure Controls and Procedures*

As required by Rules 13a-15 and 15d-15 under the Exchange Act, Dr. Suying Liu, our Chief Executive Officer and Chief Financial Officer, carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as of June 30, 2025. Based upon his evaluation, he concluded that our disclosure controls and procedures (as defined in Rules 13a-15 € and 15d-15 € under the Exchange Act) were not effective.

During the audit of the Form 10-K for the year ended December 31, 2023, management has identified material weaknesses in internal controls due to the restatements to our December 31, 2022, March 31, 2023, June 30, 2023 and September 30, 2023 financial statements ("restatements") regarding the improper classification of the Investment held in Trust Account and Deferred underwriting fee payable as current asset and liability, respectively, in our financial statements and the errors in earnings (loss) per share. In addition, the material weaknesses identified in December 31, 2023 financial reporting includes improper recognition of an invoice received which is identified during the review of the Form 10-Q for the quarter ended March 31, 2024.

Additionally, during the review of the Form 10-Q for the period ended March 31, 2024, management has identified a material weakness in internal controls due to the Company's inability to timely file the Annual Report on Form 10-K for the year ended December 31, 2023, as well as the subsequent Quarterly Report on Form 10-Q for the period ended March 31, 2024 and June 30, 2024. On October 4, 2024, the Company filed the June 30, 2024 10-Q with the SEC. On October 30, 2024, the Company received a letter from Nasdaq stating that the Company had regained compliance with the Listing Rule and that the matter is now closed.

While we have processes to identify and appropriately apply applicable accounting requirements, we plan to continue to enhance our system of evaluating and implementing the accounting standards that apply to our financial statements, including through enhanced analyses by our personnel and third-party professionals with whom we consult regarding complex accounting applications. The elements of our remediation plan can only be accomplished over time, and we can offer no assurance that these initiatives will ultimately have the intended effects.

*Changes in Internal Control Over Financial Reporting*

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

**PART II - OTHER INFORMATION**

**Item 1. Legal Proceedings**

None

**Item 1A. Risk Factors**

Factors that could cause our actual results to differ materially from those in this Quarterly Report are any of the risks described in our Annual Report on Form 10-K filed with the SEC on April 1, 2025. Any of these factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risk factors not presently known to us or that we currently deem immaterial may also impair our business or results of operations. As of the date of this Quarterly Report, other than as described below, there have been no material changes to the risk factors disclosed in our Annual Report on Form 10-K filed with the SEC on April 1, 2025.
