Significant Accounting Policies [Abstract]

Emerging Growth Company Status

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

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

Cash and Cash Equivalents

Cash and Cash Equivalents

NewHold considers all highly liquid instruments with original maturities of three months or less when acquired to be cash equivalents. NewHold had approximately $364,000 and $1,198,000, respectively, invested in cash equivalents (money market funds, which are a Level 1 input as they are quoted in active markets) as of June 30, 2026 and December 31, 2025. The cash equivalents are stated at their fair value, $364,000 and $1,198,000 at June 30, 2026 and December 31, 2025 as shown in the table below:

Description at June 30, 2026	Quoted Price Prices in Active Markets (Level 1)
Assets:
Money market funds	$	364,000

Description at December 31, 2025	Quoted Price Prices in Active Markets (Level 1)

Money market funds	$	1,198,000

Concentration of Credit Risk

Concentration of Credit Risk

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

Fair Value Measurements

Fair Value Measurements

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

●

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

●

Level 2, defined as inputs other than quoted prices in active markets that are either directly or indirectly observable such as quoted prices for similar instruments in active markets or quoted prices for identical or similar instruments in markets that are not active; and

●

Level 3, defined as unobservable inputs in which little or no market data exists, therefore requiring an entity to develop its own assumptions, such as valuations derived from valuation techniques in which one or more significant inputs or significant value drivers are unobservable. In some circumstances, the inputs used to measure fair value might be categorized within different levels of the fair value hierarchy. In those instances, the fair value measurement is categorized in its entirety in the fair value hierarchy based on the lowest level input that is significant to the fair value measurement.

Offering Costs

Offering Costs

NewHold complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, “Expenses of Offering.” Deferred offering costs consist principally of professional and registration fees that are related to the Public Offering. FASB ASC 470-20, “Debt with Conversion and Other Options,” addresses the allocation of proceeds from the issuance of convertible debt into its equity and debt components. NewHold applies this guidance to allocate Public Offering proceeds from the Public Units between Class A ordinary shares and warrants, using the residual method by allocating Public Offering proceeds first to assigned value of the warrants and then to the Class A ordinary shares. Offering costs allocated to the Class A ordinary shares subject to possible redemption are charged to temporary equity and offering costs allocated to the warrants included in the Public Units and Private Placement Units are charged to shareholders’ deficit as the warrants included in the Public Units and Private Placement Units after management’s evaluation are accounted for under equity treatment.

During the six months ended June 30, 2025, offering costs amounted to approximately $11,645,000, consisting of $4,075,000 of upfront discount and expenses to the underwriters, approximately $7,044,000 of deferred underwriting fees and $526,000 of other offering costs. Approximately $107,000 of such costs was allocated to the Public Warrants and the Private Placement Units and the remainder, approximately $11,538,000, was allocated to Class A ordinary shares subject to redemption, based on their relative fair values.

Warrant Instruments

Warrant Instruments

NewHold accounts for the Warrants issued in connection with the Public Offering and the private placement in accordance with the guidance contained in FASB ASC Topic 815, “Derivatives and Hedging”. Accordingly, NewHold evaluated and has classified the warrant instruments under equity treatment at their assigned values. There are an aggregate 10,452,550 Warrants to purchase an aggregate 10,452,550 Class A ordinary shares currently included in the Units sold in the Public Offering and the Private Placement as of June 30, 2026 (see Notes 5 and 9) and no warrants outstanding at December 31, 2025.

Income Taxes

Income Taxes

NewHold accounts for income taxes under ASC Topic 740, “Income Taxes,” 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 financial statement 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 Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. NewHold’s management determined that the Cayman Islands is NewHold’s major tax jurisdiction. NewHold recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of June 30, 2026, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. NewHold is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

NewHold 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, NewHold’s tax liability was zero at both June 30, 2026 and December 31, 2025.
