Newbury Street II Acquisition Corp 10-K

Item 9A. Controls and Procedures. Evaluation of Disclosure Controls and Procedures Disclosure controls and procedures are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this Report, is recorded, processed, summarized, and reported within the time periods specified in the SEC’s rules and forms. Disclosure controls and procedures are also designed with the objective of ensuring that such information is accumulated and communicated to our Management, including our Certifying Officers, as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our Management, including our Certifying Officers, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on the foregoing, our Certifying Officers concluded that our disclosure controls and procedures were effective as of December 31, 2025. We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions. 35 Management’s Annual Report on Internal Control over Financial Reporting As required by SEC rules and regulations implementing Section 404 of the Sarbanes-Oxley Act, our Management is responsible for establishing and maintaining adequate internal control over financial reporting. Our internal control over financial reporting is designed to provide reasonable assurance regarding the reliability of financial reporting and the preparation of our financial statements for external reporting purposes in accordance with GAAP. Our internal control over financial reporting includes those policies and procedures that: (1) pertain to the maintenance of records that, in reasonable detail, accurately and fairly reflect the transactions and dispositions of the assets of our Company, (2) provide reasonable assurance that transactions are recorded as necessary to permit preparation of financial statements in accordance with GAAP, and that our receipts and expenditures are being made only in accordance with authorizations of our Management and directors, and (3) provide reasonable assurance regarding prevention or timely detection of unauthorized acquisition, use or disposition of our assets that could have a material effect on the financial statements. Because of its inherent limitations, internal control over financial reporting may not prevent or detect errors or misstatements in our financial statements. Also, projections of any evaluation of effectiveness to future periods are subject to the risk that controls may become inadequate because of changes in conditions, or that the degree or compliance with the policies or procedures may deteriorate. Management assessed the effectiveness of our internal control over financial reporting as of December 31, 2025. In making these assessments, Management used the criteria set forth by the Committee of Sponsoring Organizations of the Treadway Commission (COSO) in Internal Control — Integrated Framework (2013). Based on our assessments and those criteria, Management determined that we maintained effective internal control over financial reporting as of December 31, 2025. This Report does not include an attestation report of our internal controls from our independent registered public accounting firm due to our status as an emerging growth company under the JOBS Act. Changes in Internal Control over Financial Reporting There have been no changes to our internal control over financial reporting during the quarterly period ended December 31, 2025 that materially affected, or are reasonably likely to materially affect, our internal control over financial reporting. Item 9B. Other Information. Trading Arrangements During the quarterly period ended December 31, 2025, none of our directors or officers (as defined in Rule 16a-1(f) promulgated under the Exchange Act) adopted or terminated any “Rule 10b5-1 trading arrangement” or any “non-Rule 10b5-1 trading arrangement,” as each term is defined in Item 408(a) of Regulation S-K. Additional Information None. Item 9C. Disclosure Regarding Foreign Jurisdictions that Prevent Inspections. Not applicable. 36 PART III Item 10. Directors, Executive Officers and Corporate Governance.

Involvement in Certain Legal Proceedings There are no material proceedings to which any director or executive officer, or any associate of any such director or officer is a party adverse to our Company, or has a material interest adverse to our Company. Number and Terms of Office of Officers and Directors Our Board of Directors consists of six members and is divided into three classes with only one class of directors being appointed in each year, and with each class (except for those directors appointed prior to our first annual general meeting) serving a three-year term. Prior to the closing of our initial Business Combination, only holders of our Class B Ordinary Shares are entitled to vote on the appointment and removal of directors. Our Public Shareholders are not entitled to vote on such matters during such time. This provision of our Amended and Restated Charters relating to these rights of holders of Class B Ordinary Shares may be amended by a Special Resolution. In accordance with Nasdaq corporate governance requirements, we are not required to hold an annual general meeting until one year after our first fiscal year end following our listing on Nasdaq. The term of office of the first class of directors, consisting of Ted Seides, will expire at our first annual general meeting. The term of office of the second class of directors, consisting of Jennifer Vescio and Josh Gold, will expire at the second annual general meeting. The term of office of the third class of directors, consisting of Anthony James Vinciquerra, William Zachre Wyatt and Thomas Bushey will expire at the third annual general meeting. Our officers are appointed by the Board of Directors and serve at the discretion of the Board of Directors, rather than for specific terms of office. Our Board of Directors is authorized to appoint persons to the offices set forth in our Amended and Restated Charter it deems appropriate. Our Amended and Restated Charter provides that our officers may consist of a Chairman, a Vice-Chairman, a Chief Executive Officer, a President, a Chief Operating Officer, a Chief Financial Officer, Vice Presidents, a Secretary, Assistant Secretaries, a Treasurer and such other offices as may be determined by the Board of Directors. Committees of the Board of Directors Our Board of Directors has established two standing committees: the Audit Committee and the Compensation Committee. Subject to phase-in rules, the Nasdaq Rules and Rule 10A-3 of the Exchange Act require that the audit committee of a listed company be comprised solely of independent directors. Each committee operates under a charter that has been approved by our Board and has the composition and responsibilities described below. Audit Committee We have established the Audit Committee. The members of our Audit Committee are Josh Gold, Jennifer Vescio and Ted Seides. Josh Gold serves as the chairman of the Audit Committee. Each member of the Audit Committee is financially literate and our Board of Directors has determined that Josh Gold qualifies as an “audit committee financial expert” as defined in applicable SEC rules and has accounting or related financial management expertise. We have adopted a charter of the Audit Committee, which details the principal functions of the Audit Committee, including: ● assisting with Board oversight of (i) the integrity of our financial statements, (ii) our compliance with legal and regulatory requirements, (iii) our independent registered public accounting firm’s qualifications and independence, and (iv) the performance of our internal audit function and independent registered public accounting firm; the appointment, compensation, retention, replacement, and oversight of the work of the independent registered public accounting firm and any other independent registered public accounting firm engaged by us; 39 ● pre-approving all audit and non-audit services to be provided by the independent registered public accounting firm or any other registered public accounting firm engaged by us, and establishing pre-approval policies and procedures; reviewing and discussing with the independent registered public accounting firm all relationships the independent registered public accounting firm have with us in order to evaluate their continued independence; ● setting clear policies for audit partner rotation in compliance with applicable laws and regulations; obtaining and reviewing a report, at least annually, from the independent registered public accounting firm describing (i) the independent registered public accounting firm’s internal quality-control procedures and (ii) any material issues raised by the most recent internal quality-control review, or peer review, of the independent registered public accounting firm, or by any inquiry or investigation by governmental or professional authorities, within the preceding five years respecting one or more independent audits carried out by the firm and any steps taken to deal with such issues; ● meeting to review and discuss our annual audited financial statements and quarterly financial statements with Management and the independent registered public accounting firm, including reviewing our specific disclosures under “Management’s Discussion and Analysis of Financial Condition and Results of Operations”; reviewing and approving any related party transaction required to be disclosed pursuant to Item 404 of Regulation S-K promulgated by the SEC prior to us entering into such transaction; ● reviewing with Management, the independent registered public accounting firm, and our legal advisors, as appropriate, any legal, regulatory or compliance matters, including any correspondence with regulators or government agencies and any employee complaints or published reports that raise material issues regarding our financial statements or accounting policies and any significant changes in accounting standards or rules promulgated by the FASB, the SEC or other regulatory authorities. ● advising the Board and any other Board committees if the clawback provisions of the SEC Clawback Rule are triggered based upon a financial statement restatement or other financial statement change, with the assistance of Management and to the extent that our securities continue to be listed on an exchange and subject to the SEC Clawback Rule; and ● implementing and overseeing our cybersecurity and information security policies, and periodically reviewing the policies and managing potential cybersecurity incidents. Compensation Committee We have established the Compensation Committee. The members of our Compensation Committee are Jennifer Vescio and Josh Gold. Jennifer Vescio serves as chairperson of the Compensation Committee. We have adopted a charter of the Compensation Committee, which details the principal functions of the Compensation Committee, including: ● reviewing and approving on an annual basis the corporate goals and objectives relevant to our Chief Executive Officer’s compensation, evaluating our Chief Executive Officer’s performance in light of such goals and objectives and determining and approving the remuneration (if any) of our Chief Executive Officer based on such evaluation; ● reviewing and making recommendations to our board of directors with respect to the compensation, and any incentive compensation and equity based plans that are subject to Board approval of all of our other officers; 40 ● reviewing our executive compensation policies and plans; ● implementing and administering our incentive compensation equity-based remuneration plans; ● assisting Management in complying with our proxy statement and annual report disclosure requirements; ● approving all special perquisites, special cash payments and other special compensation and benefit arrangements for our executive officers and employees; ● producing a report on executive compensation to be included in our annual proxy statement; ● reviewing, evaluating and recommending changes, if appropriate, to the remuneration for directors; and ● advising the Board and any other Board committees if the clawback provisions of the SEC Clawback Rule are triggered based upon a financial statement restatement or other financial statement change and perform any other tasks required of it by the Clawback Policy, with the assistance of Management and to the extent that our securities continue to be listed on an exchange and subject to the SEC Clawback Rule. The charter of the Compensation Committee also provides that the Compensation Committee may, in its sole discretion, retain or obtain the advice of a compensation consultant, independent legal counsel or other adviser and will be directly responsible for the appointment, compensation and oversight of the work of any such adviser. However, before engaging or receiving advice from a compensation consultant, external legal counsel or any other adviser, the Compensation Committee will consider the independence of each such adviser, including the factors required by the Nasdaq Rules and the SEC. Director Nominations We do not have a standing nominating committee though we intend to form a corporate governance and nominating committee as and when required to do so by law or the Nasdaq Rules. In accordance with Rule 5605(e)(2) of the Nasdaq Rules, a majority of the independent directors may recommend a director nominee for selection by our Board of Directors. Our Board of Directors believes that the independent directors can satisfactorily carry out the responsibility of properly selecting or approving director nominees without the formation of a standing nominating committee. The directors who participate in the consideration and recommendation of director nominees are Messrs. Vinciquerra, Gold, Seides, Wyatt and Ms. Vescio. In accordance with Rule 5605(e)(1)(A) of the Nasdaq Rules, all such directors are independent. As there is no standing nominating committee, we do not have a nominating committee charter in place. The Board of Directors also considers director candidates recommended for nomination by our shareholders during such times as they are seeking proposed nominees to stand for appointment at the next annual general meeting (or, if applicable, an extraordinary general meeting). Our shareholders that wish to nominate a director for appointment to our Board of Directors should follow the procedures set forth in our amended and restated memorandum and articles of association. We have not formally established any specific, minimum qualifications that must be met or skills that are necessary for directors to possess. In general, in identifying and evaluating nominees for director, our Board of Directors considers educational background, diversity of professional experience, knowledge of our business, integrity, professional reputation, independence, wisdom, and the ability to represent the best interests of our shareholders. Prior to our initial Business Combination, our Public Shareholders do not have the right to recommend director candidates for nomination to our Board of Directors. 41 Code of Ethics We have adopted the Code of Ethics. If we make any amendments to our Code of Ethics other than technical, administrative or other non-substantive amendments, or grant any waiver, including any implicit waiver, from a provision of the Code of Ethics applicable to our principal executive officer, principal financial officer, principal accounting officer or controller or persons performing similar functions requiring disclosure under applicable SEC rules or the Nasdaq Rules, we will disclose the nature of such amendment or waiver on our website. The information included on our website is not incorporated by reference into this Report or in any other report or document we file with the SEC, and any references to our website are intended to be inactive textual references only. The foregoing description of the Code of Ethics does not purport to be complete and is qualified in its entirety by the terms and conditions of the Code of Ethics, a copy of which is attached hereto as Exhibit 14. Trading Policies On October 22, 2024, we adopted the Insider Trading Policy governing the purchase, sale, and/or other dispositions of our securities by directors, officers and employees, which are reasonably designed to promote compliance with insider trading laws, rules and regulations, and applicable Nasdaq Rules. The foregoing description of the Insider Trading Policy does not purport to be complete and is qualified in its entirety by the terms and conditions of the Insider Trading Policy, a copy of which is attached hereto as Exhibit 19. Item 11. Executive Compensation. None of our directors or officers have received any cash compensation for services rendered to us. We pay an affiliate of our Sponsor a total of $10,000 per month for office space, administrative and support services pursuant to the Administrative Support Agreement. Our Sponsor, directors and officers, or any of their respective affiliates, are reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. Our Audit Committee reviews on a quarterly basis all payments that were made by us to our Sponsor, directors, officers or any of their respective affiliates. After the completion of our initial Business Combination, directors or members of our Management Team who remain with us may be paid consulting, management or other compensation from the combined company. All compensation will be fully disclosed to shareholders, to the extent then known, in the tender offer materials or proxy solicitation materials furnished to our shareholders in connection with a proposed Business Combination. It is unlikely the amount of such compensation will be known at the time, because the directors of the post-combination business will be responsible for determining executive officer and director compensation. Any compensation to be paid to our officers after the completion of our initial Business Combination will be determined by a compensation committee constituted solely by independent directors. We are not party to any agreements with our directors and officers that provide for benefits upon termination of employment. The existence or terms of any such employment or consulting arrangements may influence our Management’s motivation in identifying or selecting a target business, and we do not believe that the ability of our Management to remain with us after the consummation of our initial Business Combination should be a determining factor in our decision to proceed with any potential Business Combination. Compensation Recovery and Clawback Policy On October 22, 2024, our Board of Directors approved the adoption of the Clawback Policy in order to comply with the SEC Clawback Rule, and the Nasdaq Rules, as set forth in Nasdaq Listing Rule 5608. At no time during the fiscal year covered by this Report were we required to prepare an accounting restatement that required recovery of an erroneously awarded compensation pursuant to the Clawback Policy, a copy of which is attached hereto as Exhibit 97. 42 Item 12. Security Ownership of Certain Beneficial Owners and Management and Related Stockholder Matters. The following table sets forth information regarding the beneficial ownership of our Ordinary Shares as of March 6, 2026 based on information obtained from the persons named below, with respect to the beneficial ownership of Ordinary Shares, by: ● each person known by us to be the beneficial owner of more than 5% of our issued and outstanding Ordinary Shares; ● each of our executive officers and directors that beneficially owns our Ordinary Shares; and ● all our executive officers and directors as a group.

On all matters to be voted upon, except for (x) the appointment and removal of directors to the Board and (y) continuing our Company in a jurisdiction outside the Cayman Islands, holders of the Class A Ordinary Shares and Class B Ordinary Shares vote together as a single class, unless otherwise required by applicable law. Currently, all of the Class B Ordinary Shares are convertible into Class A Ordinary Shares on a one-for-one basis. Unless otherwise indicated, we believe that all persons named in the table have sole voting and investment power with respect to all Ordinary Shares beneficially owned by them.

On June 20, 2024, our Sponsor paid $25,000 to cover certain of our offering and formation costs in exchange for the issuance of 5,750,000 Founder Shares, or approximately $0.004 per share. On July 12, 2024, we issued an additional 368,000 Founder Shares to our Sponsor in a share capitalization resulting in our Sponsor holding a total of 6,118,000 Founder Shares. Up to 798,000 Founder Shares were subject to forfeiture depending on the extent to which the Over-Allotment Option was exercised. The Over-Allotment Option was exercised in full and such Founder Shares are no longer subject to forfeiture. Our Sponsor purchased an aggregate of 484,500 Private Placement Units following the full exercise of the Over-Allotment Option at a purchase price of $10.00 per Private Placement Unit, for an aggregate purchase price of $4,845,000 in the Private Placement that occurred simultaneously with the closing of the Initial Public Offering and pursuant to the Private Placement Units Purchase Agreement. The Private Placement Units (and underlying shares) are identical to the Public Units (and underlying shares), except as otherwise described in the Report. If any of our directors or officers becomes aware of a Business Combination opportunity that falls within the line of business of any entity to which he or she has then-current fiduciary or contractual obligations, he or she may be required to present such Business Combination opportunity to such entity prior to presenting such Business Combination opportunity to us. Our directors and officers currently have certain relevant fiduciary duties or contractual obligations that may take priority over their duties to us. 45 Members of our Management Team and our Board of Directors directly or indirectly own Founder Shares and/or Private Placement Units and, accordingly, may have a conflict of interest in determining whether a particular target business is an appropriate business with which to effectuate our initial Business Combination. We have entered into an Administrative Support Agreement with an affiliate of our Sponsor, pursuant to which we pay a total of $10,000 per month to such affiliate for certain office space, administrative and support services. Upon completion of our initial Business Combination or our liquidation, we will cease paying these monthly fees. Accordingly, in the event the consummation of our initial Business Combination takes 24 months, an affiliate of our Sponsor will be paid a total of $240,000 ($10,000 per month) for certain office space, administrative and support services and also is entitled to be reimbursed for any out-of-pocket expenses. As of December 31, 2025 and 2024, we incurred $120,000 and $20,000, respectively, in fees for these services. These amounts are paid and included in the general and administrative costs on the statements of operations of the financial statements included elsewhere this Report. Our Sponsor, directors and officers, or any of their respective affiliates, are reimbursed for any out-of-pocket expenses incurred in connection with activities on our behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. Our Audit Committee reviews on a quarterly basis all payments that were made to our Sponsor, directors, officers or any of their respective affiliates and determine which expenses and the amount of expenses that are reimbursed. There is no cap or ceiling on the reimbursement of out-of-pocket expenses incurred by such persons in connection with activities on our behalf. On June 4, 2024, our Sponsor agreed to loan us an aggregate of up to $300,000 under the IPO Promissory Note to cover expenses related to the Initial Public Offering. Such loans and advances were non-interest bearing and payable on the earlier of June 30, 2025 or the completion of our Initial Public Offering. The loan of $213,706 was fully repaid upon the consummation of our Initial Public Offering on November 4, 2024. No additional borrowing is available under the IPO Promissory Note. On November 4, 2024, we repaid $25,000 to the Sponsor in excess of the IPO Promissory Note. On September 26, 2025, we paid tax and accounting expenses on behalf of the Sponsor of $7,590. As of December 31, 2025 and 2024, $32,590 and $25,000, respectively, were due to be repaid to us by the Sponsor. 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 Working Capital Loans, as may be required. If we complete a Business Combination, we will repay such Working Capital Loans. 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 Working Capital Loans, but no proceeds from our Trust Account would be used for such repayment. Up to $1,500,000 of such Working Capital Loans may be converted into units of the post-Business Combination entity at a price of $10.00 per unit. The units (and underlying securities) would be identical to the Private Placement Units (and underlying securities). Other than as set forth above, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such Working Capital Loans. As of December 31, 2025 and 2024, we did not have any borrowings under any Working Capital Loans. We do not expect to seek loans from parties other than Sponsor or an affiliate of our Sponsor as we do not believe third parties will be willing to loan such funds and provide a waiver against any and all rights to seek access to funds in our Trust Account. After our initial Business Combination, members of our Management Team who remain with us may be paid consulting, management or other fees from the combined company with any and all amounts being fully disclosed to our shareholders, to the extent then known, in the tender offer or proxy solicitation materials, as applicable, furnished to our shareholders. It is unlikely the amount of such compensation will be known at the time of distribution of such tender offer materials or at the time of a general meeting held to consider our initial Business Combination, as applicable, as it will be up to the directors of the post-combination business to determine executive officer and director compensation. 46 Pursuant to the Registration Rights Agreement, the holders of (i) the Founder Shares, (ii) the Representative Shares, (iii) the Private Placement Units and (iv) any private placement-equivalent units issued in connection with the Working Capital Loans, if any (and in each case holders of their underlying securities, as applicable) are entitled to registration rights pursuant to the Registration Rights Agreement, requiring us to register such securities for resale (in the case of the Founder Shares, only after conversion to our Class A Ordinary Shares). The holders of the majority of these securities are entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the holders have certain “piggy-back” registration rights with respect to registration statements filed subsequent to the consummation of a Business Combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. BTIG may only make a demand on one occasion and only during the five-year period beginning on the effective date of the IPO Registration Statement. We will bear the expenses incurred in connection with the filing of any such registration statements. The Private Placement Warrants may not be exercised more than five years from the date the sales for the Initial Public Offering commenced in compliance with Rule 5110(g)(8)(A). Our Sponsor, directors and officers have entered into the Letter Agreement with us, pursuant to which, they have waived their rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if we fail to complete our initial Business Combination within the Combination Period. However, if they acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if we fail to complete our initial Business Combination within the Combination Period. Additionally, pursuant to the Letter Agreement, our Sponsor, directors and officers will not propose any amendment to our Amended and Restated Articles to modify (i) the substance or timing of our obligation to allow redemption in connection with our initial Business Combination or to redeem 100% of our Public Shares if we do not complete our initial Business Combination within the Combination Period or (ii) any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, unless we provide our Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, divided by the number of then outstanding Public Shares. Director Independence The Nasdaq Rules require that a majority of our Board of Directors be independent. An “independent director” is defined generally as a person other than an officer or employee of the company or its subsidiaries or any other individual having a relationship that in the opinion of its board of directors, would interfere with the director’s exercise of independent judgment in carrying out the responsibilities of a director. Our Board of Directors has determined that each of Anthony James Vinciquerra, Jennifer Vescio, Josh Gold, Ted Seides and William Zachre Wyatt is an independent director under applicable SEC rules and the Nasdaq Rules. 47 Item 14 .

As a result, the Audit Committee did not pre-approve all of the foregoing services, although any services rendered prior to the formation of our Audit Committee were approved by our Board of Directors. Since the formation of our Audit Committee, and on a going-forward basis, the Audit Committee has and will pre-approve all auditing services and permitted non-audit services performed and to be performed for us by our auditors, including the fees and terms thereof (subject to the de minimis exceptions for non-audit services described in the Exchange Act which are approved by the Audit Committee prior to the completion of the audit). 48 PART IV Item 15.

In our opinion, the financial statements present fairly, in all material respects, the financial position of Newbury Street II Acquisition Corp as of December 31, 2025 and 2024, and the results of its operations and its cash flows for the year ended December 31, 2025 and for the period from June 18, 2024 (inception) through December 31, 2024 in conformity with accounting principles generally accepted in the United States of America. Going Concern The accompanying financial statements have been prepared assuming that the Company will continue as a going concern. As discussed in Note 1 to the financial statements, if the Company is unable complete a business combination by November 4, 2026, then the Company will cease all operations except for the purpose of liquidating. The date for mandatory liquidation and subsequent dissolution raises substantial doubt about the Company's ability to continue as a going concern. Management's plans in regard to these matters are also described in Note 1. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Basis for Opinion These financial statements are the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statements based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) ("PCAOB") and are required to be independent with respect to Newbury Street II Acquisition Corp in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB. We conducted our audits in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audits to obtain reasonable assurance about whether the financial statements are free of material misstatement, whether due to error or fraud. Newbury Street II Acquisition Corp. is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting. As part of our audits, we are required to obtain an understanding of internal control over financial reporting but not for the purpose of expressing an opinion on the effectiveness of the Company’s internal control over financial reporting. Accordingly, we express no such opinion. Our audits included performing procedures to assess the risks of material misstatement of the financial statements, whether due to error or fraud, and performing procedures that respond to those risks. Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statements. Our audits also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statements. We believe that our audits provide a reasonable basis for our opinion. /s/ WithumSmith+Brown, PC We have served as the Company's auditor since 2024.

F- 6 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 NOTE 1 . DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS Organization and General Newbury Street II Acquisition Corp ( the “ Company ”) was incorporated as a Cayman Islands exempted company on June 18, 2024 . The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”) that the Company has not yet identified. The Company is an “emerging growth company,” as defined in Section 2(a) of the Securities Act of 1933, as amended (the “Securities Act”), as modified by the Jumpstart Our Business Startups Act of 2012 (the “JOBS Act”). As of December 31, 2025, the Company had not entered into a definitive agreement with any specific Business Combination target. As of December 31, 2025, the Company had not yet commenced operations. All activity for the period from June 18, 2024 (inception) through December 31, 2025 related to the Company’s formation and the Initial Public Offering (as defined below), and subsequent to the Initial Public Offering (as defined below), identifying and evaluating prospective acquisition candidates and activities in connection with the Business Combination. The Company will not generate any operating revenue 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 Company has selected December 31 as its fiscal year end. Sponsor and Initial Financing The Company’s sponsor is Newbury Street II Acquisition Sponsor LLC (the “Sponsor”). The Registration Statement on Form S-1 for the Initial Public Offering, initially filed with the U.S. Securities and Exchange Commission (the “SEC”) on August 9, 2024, as amended (File No. 333-281456), was declared effective on October 31, 2024 (the “IPO Registration Statement”). On November 4, 2024, the Company consummated the initial public offering of 17,250,000 units (the “Public Units”), which included the full exercise of the Over-Allotment Option (as defined in Note 6) in the amount of 2,250,000 units (the “Option Units”), at $ 10.00 per Public Unit, generating gross proceeds of $ 172,500,000 , which is described in Note 3 (the “Initial Public Offering”). Each Public Unit consists of one Class A ordinary share, par value $ 0.0001 per share, of the Company (the “Class A Ordinary Shares” and with respect to the Class A Ordinary Shares included in the Public Units, the “Public Shares”) and one-half of one redeemable warrant (each, a “Public Warrant”). Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 648,375 units (the “Private Placement Units”, and together with the Public Units, the “Units”) at a price of $ 10.00 per Private Placement Unit to the Sponsor and BTIG, LLC (“BTIG”), the underwriter in the Initial Public Offering (the “Underwriter”), in a private placement, generating gross proceeds of $ 6,483,750 , which is described in Note 4 (the “Private Placement”). Of those 648,375 Private Placement Units, the Sponsor purchased 484,500 Private Placement Units and BTIG purchased 163,875 Private Placement Units. Each Private Placement Unit consists of one Class A Ordinary Share (the “Private Placement Shares”) and one-half of one warrant (the “Private Placement Warrants”, and together with the Public Warrants, the “Warrants”). Transaction costs amounted to $ 10,113,129 , consisting of $ 3,450,000 of cash underwriting fee, the Deferred Fee of $ 6,037,500 (as defined in Note 6), and $ 625,629 of other offering costs. F- 7 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 The Trust Account Following the closing of the Initial Public Offering, on November 4, 2024, an amount of $ 173,362,500 ($ 10.05 per Public Unit) from the net proceeds of the Initial Public Offering and the Private Placement was placed in a trust account (the “Trust Account”) with Continental Stock Transfer & Trust Company (“Continental”), acting as trustee. The funds in the Trust Account are held only in (i) U.S. Department of the Treasury (the “Treasury”) bills with a maturity of 185 days or less or in money market funds investing solely in Treasuries obligations, (ii) uninvested cash, or (iii) an interest-bearing bank demand deposit account or other accounts at a bank that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940, as amended (the “Investment Company Act”). The funds will remain in the Trust Account until the earlier of (x) the consummation of the initial Business Combination or (y) the distribution of the Trust Account proceeds as described below. As of the accompanying balance sheet date, these funds were held in money market accounts. Initial Business Combination The Company’s management (“Management”) has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, although substantially all of the net proceeds of the Initial Public Offering are intended to be generally applied toward consummating a Business Combination. The initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80 % of the assets held in the Trust Account (excluding the Deferred Fee and taxes payable, if any, on income earned on the Trust Account) at the time of the agreement to enter into the Business Combination. Furthermore, there is no assurance that the Company will be able to successfully consummate a Business Combination. The Company will provide the holders of Public Shares (the “Public Shareholders”) with the opportunity to redeem, regardless of whether they abstain, vote for, or against, the initial Business Combination, all or a portion of their Public Shares upon the completion of the initial Business Combination either (i) in connection with a general meeting called to approve the initial Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a proposed Business Combination or conduct a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would require the Company to seek shareholder approval under applicable law or stock exchange listing requirement. Asset acquisitions and share purchases would not typically require shareholder approval while direct mergers with the Company where it does not survive and any transactions where the Company issues more than 20 % of the issued and outstanding Ordinary Shares (as defined in Note 5) or seek to the Company’s amend the amended and restated memorandum and articles of association (as currently in effect, the “Amended and Restated Articles”) would typically require shareholder approval. The Company intends to conduct redemptions without a shareholder vote pursuant to the tender offer rules of the SEC unless shareholder approval is required by applicable law or stock exchange listing rules, or the Company chooses to seek shareholder approval for business or other reasons. The Amended and Restated Articles provides that the Company has until November 4, 2026, or such earlier liquidation date as the Company’s board of directors (the “Board”) may approve to consummate the initial Business Combination (the “Combination Period”). If the Company is unable to complete the initial 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 (and subject to lawfully available funds therefor), redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (less up to $ 100,000 of interest to pay dissolution expenses and net of taxes payable, if any), divided by the number of then-outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Board, liquidate and dissolve, subject in each case to the obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There will be no redemption rights or liquidating distributions with respect to the Warrants, which will expire without value to the holder if the Company fails to complete the initial Business Combination within the Combination Period. F- 8 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 The Sponsor and the Company’s executive officers and directors have entered into a letter agreement with the Company, dated October 31, 2024 (the “Letter Agreement”), pursuant to which they have waived their rights to liquidating distributions from the Trust Account with respect to their Founder Shares (as defined in Note 5) and Private Placement Shares if the Company fails to complete the initial Business Combination within the Combination Period. However, if the Sponsor and the Company’s executive officers and directors acquire Public Shares, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if the Company fails to complete the initial Business Combination within the Combination Period. The Underwriter has agreed to waive its rights to the Deferred Fee 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 funds held in the Trust Account that will be available to fund the redemption of the Public Shares. The Sponsor, and the Company’s executive officers and directors have also agreed, pursuant to the Letter Agreement, that they will not propose any amendment to the Amended and Restated Articles (i) in that would modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100 % of the Public Shares if the Company does not complete the initial Business Combination within the Combination Period or (ii) with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, in each case unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of taxes payable, if any), divided by the number of then issued and outstanding Public Shares. Board and Audit Committee Changes On May 28, 2025, Matthew Hong notified the Board of his resignation as a member and chairman of the Board and a member and chair of the audit committee of the Board (the “Audit Committee”), effective as of the same day. On May 28, 2025, the Board appointed Anthony James Vinciquerra and William Zachre Wyatt as directors of the Board (the “New Directors”). Effective as of May 28, 2025, Mr. Vinciquerra was appointed as chairman of the Board, Ted Seides, a director of the Company, was appointed as a member of the Audit Committee, and Josh Gold, a director and member of the Audit Committee, was appointed as chair of the Audit Committee. The New Directors serve as Class III Directors of the Board, whose term will expire at the Company’s third annual general meeting. In connection with the appointments, the New Directors signed a joinder to the Letter Agreement, pursuant to which, among other things, they agreed to waive certain redemption rights and to vote any Ordinary Shares they hold in favor of an initial Business Combination. The New Directors also entered into a standard director indemnity agreement with the Company. Each of the New Directors will also receive membership interests in the Sponsor representing ownership of certain Class B Ordinary Shares solely upon consummation of the Business Combination with a target introduced by such director. Risks and Uncertainties The Company’s ability to complete an initial Business Combination may be adversely affected by various factors, many of which are beyond the Company’s control. The Company’s ability to consummate an initial Business Combination could be impacted by, among other things, changes in laws or regulations, downturns in the financial markets or in economic conditions, inflation, fluctuations in interest rates, increases in tariffs, supply chain disruptions, declines in consumer confidence and spending, public health considerations, and geopolitical instability, such as the military conflicts in Ukraine and the Middle East. The Company cannot at this time predict the likelihood of one or more of the above events, their duration or magnitude or the extent to which they may negatively impact the Company’s ability to complete an initial Business Combination. F- 9 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 Liquidity, Capital Resources and Going Concern The Company has a mandatory liquidation date of November 4, 2026, the end of the Combination Period, at which time it will cease all operations except for the purpose of winding up, redeeming public shares, and liquidating. As of December 31, 2025, the Company had working capital of $ 748,963 and cash outside the Trust Account available to fund ongoing operating expenses. In accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 205-40, “Presentation of Financial Statements – Going Concern,” Management has evaluated whether conditions and events raise substantial doubt about the Company’s ability to continue as a going concern within one year after the date that the accompanying financial statements were issued. The Company’s liquidity needs through the liquidation date will depend on the level of transaction costs and the timing of a potential Business Combination. While the current working capital is expected to be sufficient to fund operations for 12 months from the issuance of the accompanying financial statements, if additional expenses are incurred or the Business Combination process extends significantly, the Company may need to seek additional financing from the Sponsor or third parties. If the Company is unable to complete a Business Combination by November 4, 2026, it will liquidate the Trust Account and distribute the funds to its Public Shareholders. This condition raises substantial doubt about the Company’s ability to continue as a going concern. The accompanying financial statements do not include any adjustments that might result from the outcome of this uncertainty. NOTE 2. SIGNIFICANT ACCOUNTING POLICIES Basis of Presentation The accompanying financial statements are presented in U.S. dollars and have been prepared in accordance with accounting principles generally accepted in the United States of America (“GAAP”) and pursuant to the accounting and disclosure rules and regulations of the SEC. Emerging Growth Company Status The Company is an “emerging growth company”, as defined in Section 2(a) of the Securities Act, as modified by the JOBS Act, and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved. Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) 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 accompanying financial statements with another public company that is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used. F- 10 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 Use of Estimates The preparation of the accompanying financial statements in conformity with GAAP requires Management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the accompanying financial statements and the reported amounts of expenses during the reporting period. Making estimates requires Management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the accompanying financial statements, which Management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates. Cash and Cash Equivalents The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had $ 772,506 and $ 1,237,201 in cash and no cash equivalents as of December 31, 2025 and 2024, respectively. Securities Held in Trust Account As of December 31, 2025 and 2024, the assets held in the Trust Account, amounting to $ 181,847,374 and $ 174,580,335 , respectively, were held in money market funds investing in Treasury bills. Financial Instruments The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC Topic 820, “Fair Value Measurement,” approximates the carrying amounts represented in the accompanying balance sheets, primarily due to their short-term nature. Concentration of Credit Risk Financial instruments that potentially subject the Company to concentrations of credit risk consist of a cash account in a financial institution, which, at times, may exceed the Federal Deposit Insurance Corporation coverage limit of $ 250,000 . Any loss incurred or a lack of access to such funds could have a significant adverse impact on the Company’s financial condition, results of operations, and cash flows. Offering Costs Associated with the Initial Public Offering The Company complies with the requirements of FASB ASC Topic 340-10-S99, “Other Assets and Deferred Costs”, and SEC Staff Accounting Bulletin Topic 5A, — “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Initial Public Offering. FASB ASC Topic 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. The Company applied this guidance to allocate Initial Public Offering proceeds from the Public Units between Public Shares and Public Warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the Public Warrants and then to the Public Shares. Offering costs allocated to Public Shares were charged to temporary equity. Offering costs allocated to the Public Warrants and Private Placement Warrants were charged to shareholders’ deficit. After Management’s evaluation, the Warrants were accounted for under equity treatment. F- 11 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 Income Taxes The Company accounts for income taxes under FASB ASC Topic 740, “Income Taxes” (“ASC 740”), which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the accompanying financial statements and tax bases of assets and liabilities that will result in future taxable or deductible amounts, based on enacted tax laws and rates applicable to the periods in which the differences are expected to affect taxable income. Valuation allowances are established, when necessary, to reduce deferred tax assets to the amount expected to be realized. ASC 740 prescribes a recognition threshold and a measurement attribute for the accompanying financial statements recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. Management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of December 31, 2025 and 2024, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position. The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the periods presented. Warrant Instruments The Company accounted for the Warrants issued in connection with the Initial Public Offering and the Private Placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging.” Accordingly, the Company evaluated and recorded the warrant instruments under equity treatment at their assigned values. Net Income per Ordinary Share Net income per Ordinary Share is computed by dividing net income by the weighted average number of Ordinary Shares outstanding during the period, excluding Ordinary Shares subject to forfeiture. For the period from June 18, 2024 (inception) through December 31, 2024, weighted average Ordinary Shares were reduced for the effect of an aggregate of 798,000 Founder Shares that were subject to forfeiture if the Over-Allotment Option was not exercised (see Note 5). As of December 31, 2025, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into Ordinary Shares and then share in the earnings of the Company. As a result, diluted income per Ordinary Share is the same as basic income per Ordinary Share for the periods presented. For the Year Ended December 31, 2025 For the Period from June 18, 2024 (inception) through December 31, 2024 Ordinary Shares subject to possible redemption Numerator: Net income allocable to Ordinary Shares subject to possible redemption $ 4,735,874 $ 487,178 Denominator: Weighted average shares outstanding, redeemable Ordinary Shares 17,250,000 5,016,582 Basic and diluted net income per share, redeemable Ordinary Shares $ 0.27 $ 0.10 Non-redeemable Ordinary Shares Numerator: Net income allocable to common stock not subject to redemption $ 1,885,118 $ 555,046 Denominator: Weighted average shares outstanding, non-redeemable Ordinary Shares 6,866,375 5,715,425 Basic and diluted net income per share, non-redeemable Ordinary Shares $ 0.27 $ 0.10 F- 12 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 Class A Ordinary Shares Subject to Possible Redemption The Public Shares contain a redemption feature that allows for the redemption of such Public Shares in connection with the Company’s liquidation, or if there is a shareholder vote or tender offer in connection with the initial Business Combination and with amendments to the Amended and Restated Articles. In accordance with FASB ASC Topic 480-10-S99, “Distinguishing Liabilities from Equity”, the Company classifies Public Shares subject to redemption outside of permanent equity as the redemption provisions are not solely within the control of the Company. The Company recognizes changes in redemption value immediately as they occur and will adjust the carrying value of redeemable Public Shares to equal the redemption value at the end of each reporting period. Immediately upon the closing of the Initial Public Offering, the Company recognized the accretion from initial book value to redemption value. The change in the carrying value of redeemable Public Shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. As of December 31, 2025 and 2024, the Class A Ordinary Shares subject to possible redemption reflected in the accompanying balance sheets are reconciled in the following table: As of December 31, 2025 As of December 31, 2024 Balance brought forward $ 174,580,335 $ — Gross proceeds — 172,500,000 Less: Proceeds allocated to Public Warrants — ( 517,500 ) Public Shares issuance costs — ( 10,808,941 ) Plus: Remeasurement of carrying value to redemption value 7,267,039 13,406,776 Class A Ordinary Shares subject to possible redemption $ 181,847,374 $ 174,580,335 Recently Issued Accounting Standards In November 2023, the FASB issued Accounting Standards Update (“ASU”) Topic 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures” (“ASU 2023-07”), which requires the disclosure of additional segment information. ASU 2023-07 is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024. The Company adopted ASU 2023-07 as of March 31, 2025 (see Note 9). Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the accompanying financial statements. NOTE 3. INITIAL PUBLIC OFFERING On November 4, 2024, the Company sold 17,250,000 Public Units, which included the full exercise of Over-Allotment Option in the amount of 2,250,000 Option Units, at a price of $ 10.00 per Public Unit. Each Public Unit consists of one Public Share and one-half of one Public Warrant. Each whole Public Warrant entitles the holder to purchase one Class A Ordinary Share at a price of $ 11.50 per share, subject to adjustments (see Note 7). NOTE 4. PRIVATE PLACEMENT Simultaneously with the closing of the Initial Public Offering, the Sponsor and BTIG purchased an aggregate of 648,375 Private Placement Units, at a price of $ 10.00 per Private Placement Unit, for an aggregate purchase price of $ 6,483,750 . Each Private Placement Unit consists of one Private Placement Share and one -half of one Private Placement Warrant. Each whole Private Placement Warrant entitles the holder to purchase one Class A Ordinary Share at a price of $ 11.50 per share, subject to adjustments (see Note 7). The Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants. With certain limited exceptions, the Private Placement Warrants (including the Class A Ordinary Shares issuable upon exercise thereof) will not be transferable, assignable or salable until 30 days after the completion of the initial Business Combination and they will not be redeemable by the Company. If the initial Business Combination is not completed within the Combination Period, the proceeds from the Initial Public Offering and the Private Placement held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law). F- 13 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 NOTE 5. RELATED PARTY TRANSACTIONS Founder Shares On June 20, 2024, the Company issued an aggregate of 5,750,000 Class B ordinary shares of the Company, $ 0.0001 par value (the “Class B Ordinary Shares”, and together with the “Class A Ordinary Shares, the “Ordinary Shares”) to the Sponsor in a private placement prior to the Initial Public Offering (the “Founder Shares”, which unless the context otherwise requires, includes the Class A Ordinary Shares issuable upon conversion thereof), in exchange for a $ 25,000 payment (approximately $ 0.004 per share) from the Sponsor to cover certain expenses on behalf of the Company. On July 12, 2024, the Company issued an additional 368,000 Founder Shares to the Sponsor, resulting in the Sponsor holding a total of 6,118,000 Founder Shares. The Founder Shares are identical to the Public Shares included in the Public Units, except that the Founder Shares automatically convert into Class A Ordinary Shares at the time of the initial Business Combination or earlier at the option of the holder, and are subject to certain transfer restrictions, as described in more detail below. The Sponsor had agreed to forfeit up to an aggregate of 798,000 Founder Shares to the extent that the Over-Allotment Option was not exercised in full, so that the Founder Shares would represent approximately 25 % of the Company’s issued and outstanding Ordinary Shares after the Initial Public Offering. On November 4, 2024, the Over-Allotment Option was exercised in full as part of the closing of the Initial Public Offering. As such, 798,000 Founder Shares are no longer subject to forfeiture. The Sponsor is not entitled to redemption rights with respect to any Founder Shares, Private Placement Shares and any Public Shares held by the Sponsor in connection with the completion of the initial Business Combination. If the initial Business Combination is not completed within the Combination Period, the Sponsor will not be entitled to liquidating distributions from the Trust Account with respect to any Founder Shares or Private Placement Shares held by it. Pursuant to the Letter Agreement, the Sponsor has agreed not to transfer, assign or sell any of its Founder Shares until the earlier to occur of (i) one year after the completion of the initial Business Combination or (ii) subsequent to the initial Business Combination (x) if the last reported sale price of the Class A Ordinary Shares equals or exceeds $ 12.00 per share (as adjusted for share subdivisions, share dividends, rights issuances, reorganizations, recapitalizations and the like) for any 20 trading days within any 30 -trading day period commencing at least 150 days after the initial Business Combination or (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the Public Shareholders having the right to exchange their Public Shares for cash, securities or other property. Registration Rights Agreement The holders of the (i) Founder Shares, (ii) Representative Shares (as defined in Note 6), (iii) Private Placement Units (including the underlying securities) and any private placement equivalent units (and underlying securities) that may be issued on conversion of any Working Capital Loans (as defined below) and (iv) Class A Ordinary Shares upon conversion of the Founder Shares are entitled to registration rights pursuant to a registration rights agreement , dated October 31, 2024, by and among the Company and certain security holders (the “Registration Rights Agreement”). The Registration Rights Agreement requires the Company to register such securities for resale (in the case of the Founder Shares, only after conversion to Class A Ordinary Shares). The holders of these securities are entitled to make up to three demands, excluding short form registration demands, that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination and rights to require the Company to register for resale such securities pursuant to Rule 415 under the Securities Act. The Company will bear the expenses incurred in connection with the filing of any such registration statements. Administrative Support Agreement Commencing on November 1, 2024, the Company entered into an administrative services agreement, dated October 31, 2024, with an affiliate of the Sponsor, pursuant to which, the Company agreed to pay the affiliate of the Sponsor thereof an amount equal to $ 10,000 per month for office space, utilities and secretarial and administrative support. Upon completion of the initial Business Combination or the Company’s liquidation, the Company will cease paying these monthly fees. As of December 31, 2025 and 2024, the Company incurred $ 120,000 and $ 20,000 , respectively, in fees for these services. These amounts are paid and included in the general and administrative costs on the accompanying statements of operations. F- 14 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 IPO Promissory Note On June 20, 2024, the Company and the Sponsor entered into a promissory note, whereby the Sponsor agreed to loan the Company an aggregate of up to $ 300,000 to cover expenses related to the Initial Public Offering (the “IPO Promissory Note”). The IPO Promissory Note was non-interest bearing and payable on the earlier of June 30, 2025, or the date on which the Company consummated the Initial Public Offering. On November 4, 2024, the Company repaid the total outstanding balance of the IPO Promissory Note and as of December 31, 2025, there was $ 0 outstanding under the IPO Promissory Note. Borrowings under the IPO Promissory Note are no longer available. Due from Sponsor On November 4, 2024, the Company repaid $ 25,000 to the Sponsor in excess of the IPO Promissory Note. On September 26, 2025, the Company paid tax and accounting expenses on behalf of the Sponsor of $ 7,590 . As of December 31, 2025 and 2024, $ 32,590 and $ 25,000 , respectively, were due to be repaid to the Company from the Sponsor. Working Capital Loans In order to finance transaction costs in connection with its initial Business Combination, the Sponsor or an affiliate of the Sponsor, or the Company’s officers and directors may, but are not obligated to, loan the Company funds as may be required (the “Working Capital Loans”). If the Company completes its initial Business Combination, the Company will repay the Working Capital Loans. In the event that the initial Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. If the Sponsor makes any Working Capital Loans, up to $ 1,500,000 of such Working Capital Loans may be convertible into units of the post-Business Combination entity at a price of $ 10.00 per unit at the option of the lender. The units and their underlying securities would be identical to the Private Placement Units and their underlying securities. The terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such Working Capital Loans. As of December 31, 2025 and 2024 , the Company had no borrowings under the Working Capital Loans. NOTE 6. COMMITMENTS AND CONTINGENCIES Underwriting Agreement The Company granted BTIG a 45 -day option to purchase up to 2,250,000 O ption Units to cover any over-allotments at the Initial Public Offering price, less the underwriting discounts and commissions (the “Over-Allotment Option”). On November 4, 2024, in connection with the closing of the Initial Public Offering, the Underwriter exercised its Over-Allotment Option in full and purchased the 2,250,000 Option Units at $ 10.00 per Option Unit. The Company paid an underwriting discount of 2.0 % of the per Public Unit offering price to BTIG at the closing of the Initial Public Offering, or $ 3,450,000 in the aggregate. In addition, BTIG is entitled to an additional fee of 3.5 % of the gross offering proceeds payable only upon the Company’s completion of its initial Business Combination, or $ 6,037,500 in the aggregate (the “Deferred Fee”). The Deferred Fee will become payable to the Underwriter from the amounts held in the Trust Account solely in the event the Company completes its initial Business Combination. Representative Shares The Company issued to BTIG, the underwriter of the Initial Public Offering, 100,000 Class A Ordinary Shares in connection with the Initial Public Offering (the “Representative Shares”). The Company accounted for the Representative Shares as an expense of the Initial Public Offering, resulting in a charge directly to shareholders’ deficit. BTIG has agreed not to transfer, assign or sell any such Representative Shares without the Company’s prior consent until the completion of the initial Business Combination. In addition, the Representative Shares are deemed to be underwriting compensation by the Financial Industry Regulatory Authority, Inc. (“FINRA”) pursuant to FINRA Rule 5110 and are, accordingly, subject to certain transfer restrictions or a period of 180 days beginning at the Initial Public Offering. Furthermore, BTIG agreed (and any of its designees to whom the Representative Shares are issued will agree) (i) to waive its redemption rights (or right to participate in any tender offer) with respect to such Representative Shares in connection with the completion of the initial Business Combination and (ii) to waive its rights to liquidating distributions from the Trust Account with respect to such Representative Shares if the Company fails to complete a Business Combination within the Combination Period. F- 15 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 Transaction Costs Related to Initial Business Combination As of December 31, 2025, the Company had incurred $ 13,470 of legal fees and $ 10,000 of advisory fees, of which $ 9,440 was paid and $ 14,030 is accrued as of the balance sheet date. NOTE 7. SHAREHOLDERS’ DEFICIT Preference Shares The Company is authorized to issue 5,000,000 preference shares with a par value of $ 0.0001 per share with such designations, voting and other rights and preferences as may be determined from time to time by the Board. As of December 31, 2025 and 2024, there were no preference shares issued or outstanding. Ordinary Shares The authorized Ordinary Shares include up to (i) 500,000,000 Class A Ordinary Shares with a par value of $ 0.0001 per share, and (ii) 50,000,000 Class B Ordinary Shares, with a par value of $ 0.0001 per share. If the Company enters into an initial Business Combination, it may (depending on the terms of such initial Business Combination) be required to increase the number of Class A Ordinary Shares that the Company is authorized to issue at the same time as the Company’s shareholders vote on the initial Business Combination to the extent the Company seeks shareholder approval in connection with the initial Business Combination. Holders of the Ordinary Shares are entitled to one vote for each Ordinary Share (except as otherwise expressed in the Amended and Restated Articles). Only holders of Class B Ordinary Shares (i) have the right to appoint and remove directors prior to or in connection with the completion of the initial Business Combination and (ii) are entitled to vote on continuing the Company in a jurisdiction outside the Cayman Islands. The Sponsor agreed to forfeit up to an aggregate of 798,000 Founder Shares depending on the extent to which the Over-Allotment Option was not exercised by the Underwriter so that the Founder Shares would represent 25 % of the Company’s issued and outstanding shares after the Initial Public Offering. On November 4, 2024, the Underwriter exercised its Over-Allotment Option in full as part of the closing of the Initial Public Offering. As such, 798,000 Founder Shares are no longer subject to forfeiture. As of December 31, 2025 and 2024, there were (i) 748,375 Class A Ordinary Shares issued and outstanding, excluding 17,250,000 Class A Ordinary Shares subject to possible redemption, and (ii) 6,118,000 Class B Ordinary Shares issued and outstanding. Warrants As of December 31, 2025 and 2024, there were 8,949,188 Warrants outstanding, including 8,625,000 Public Warrants and 324,188 Private Placement Warrants. Each whole Warrant entitles the holder thereof to purchase one Class A Ordinary Share at a price of $ 11.50 p er share, subject to adjustment as described herein, at any time commencing 30 days after the completion of the initial Business Combination, provided that the Company has an effective registration statement under the Securities Act covering the Class A Ordinary Shares issuable upon exercise of the Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Warrants on a “cashless basis” under the circumstances specified in the warrant agreement the Company entered into with Continental, dated October 31, 2024 (the “Warrant Agreement”)) and such Class A Ordinary Shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. Pursuant to the Warrant Agreement, a warrant holder may exercise its Warrants only for a whole number of Class A Ordinary Shares. This means that only a whole Warrant may be exercised at any given time by a warrant holder. No fractional Warrants will be issued upon separation of the Public Units and only whole Public Warrants will trade. The Warrants will expire five years after the completion of the initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation. F- 16 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 Public Warrants The Company has not registered Class A Ordinary Shares issuable upon exercise of the Public Warrants. However, the Company has agreed that as soon as practicable, but in no event later than 20 business days after the closing of the initial Business Combination, the Company will use its commercially reasonable efforts to file with the SEC a post-effective amendment to the IPO Registration Statement or a new registration statement registering, under the Securities Act, the issuance of the Class A Ordinary Shares issuable upon exercise of the Public Warrants. The Company will use its commercially reasonable efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Public Warrants in accordance with the provisions of the Warrant Agreement. Notwithstanding the above, if the Public Shares are at the time of any exercise of a Public Warrant not listed on a national securities exchange such that it satisfies the definition of a “covered security” under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Public Warrants who exercise their Public Warrants to do so on a “cashless basis” in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, it will not be required to file or maintain in effect a registration statement, but the Company will be required to use its commercially reasonable efforts to register or qualify the Public Shares under applicable blue sky laws to the extent an exemption is not available. Beginning 30 days after completion of the initial Business Combination, the Company may redeem the outstanding Public Warrants for cash: ● In whole and not in part; ● At a price of $ 0.01 per Public Warrant; ● Upon not less than 30 days’ prior written notice of redemption (the “ 30 -Day Redemption Period”); and ● If, and only if, the last sale price of the Class A Ordinary Shares equals or exceeds $ 18.00 per share (as adjusted for share subdivisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders. The Company will not redeem the Public Warrants as described above unless a registration statement under the Securities Act covering the Class A Ordinary Shares issuable upon exercise of the Public Warrants is effective and a current prospectus relating to those Class A Ordinary Shares is available throughout such 30 trading day period and the 30 -Day Redemption Period. Private Placement Warrants The Private Placement Warrants are non-redeemable. The Private Placement Warrants may also be exercised for cash or on a cashless basis. The Private Placement Warrants have terms and provisions that are identical to those of the Public Warrants, with certain limited exceptions, including that the Private Placement Warrants (including the Class A Ordinary Shares issuable upon exercise thereof) will not be transferable, assignable or salable until 30 days after the completion of the initial Business Combination and they will not be redeemable by the Company. 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. F- 17 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 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 assessment of the assumptions that market participants would use in pricing the asset or liability. The following table presents information about the Company’s assets that are measured at fair value as of December 31, 2025 and 2024, and indicates the fair value hierarchy of the valuation inputs the Company utilized to determine such fair value: Description Level December 31, 2025 December 31, 2024 Assets: Cash and securities held in Trust Account 1 $ 181,847,374 $ 174,580,335 Equity: Level November 4, 2024 Fair value of Public Warrants for Class A Ordinary Shares subject to possible redemption allocation 3 $ 517,500 Fair value of the Representative Shares 3 $ 748,747 The fair values of Public Warrants for Class A Ordinary Shares subject to possible redemption allocation and Representatives Shares as of November 4, 2024 (the date of the Initial Public Offering) were used in allocation of the equity components and are not revalued and remeasured in subsequent periods. The fair value of Public Warrants was determined using the Monte Carlo simulation. The Public Warrants have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the valuation of the Public Warrants: November 4, 2024 Underlying share price $ 9.93 Term (years) 6.49 Risk-free rate 4.14 % Market adjustment 5.0 % Volatility 4.0 % The fair value of the Representative Shares was determined using the Monte Carlo simulation. The Representative Shares have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the valuation of the Representative Shares: November 4, 2024 Volatility 80 % Term (years) 3 Average trading price post-Business Combination $ 6.86 Discount on market adjustment 32.0 % F- 18 NEWBURY STREET II ACQUISITION CORP NOTES TO FINANCIAL STATEMENTS DECEMBER 31, 2025 NOTE 9. SEGMENT INFORMATION FASB 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 that engage in business activities from which it may recognize revenues and incur expenses, and for which separate financial information is available that is regularly evaluated by the chief operating decision maker (“CODM”), or group, in deciding how to allocate resources and assess performance. The Company’s CODM has been identified as the Chief Financial Officer , who reviews the assets, operating results, and financial metrics for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, Management has determined that there is only one reportable segment. The CODM assesses performance for the single segment and decides how to allocate resources based on net income that also is reported on the statements of operations as net income. The measure of segment assets is reported on the accompanying balance sheets as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation, the CODM reviews several key metrics included in net income and total assets, which include the following: December 31, 2025 December 31, 2024 Cash and securities held in Trust Account $ 181,847,374 $ 174,580,335 Cash $ 772,506 $ 1,237,201 For the Year Ended December 31, 2025 For the Period from June 18, 2024 (inception) through December 31, 2024 General and administrative costs $ 688,452 $ 175,611 Interest earned on cash and securities held in Trust Account $ 7,267,039 $ 1,217,835 Interest on operating account $ 42,405 $ — The CODM reviews interest earned on marketable securities held in Trust Account to measure and monitor shareholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the Investment Management Trust Agreement, dated October 31, 2024, which the Company entered into with Continental, as trustee of the Trust Account. General and administrative costs are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a Business Combination or similar transaction within the Combination Period. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative costs, as reported on the accompanying statements of operations, are the significant segment expenses provided to the CODM on a regular basis. All other segment items included in net income are reported on the accompanying statements of operations and described within their respective disclosures. NOTE 10. SUBSEQUENT EVENTS The Company evaluated subsequent events and transactions that occurred after the accompanying balance sheet date up to the date that the accompanying 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 accompanying financial statements.
