0001829126-26-002303Year-over-year tone shift - average net-tone change across Risk Factors and MD&A vs the prior 10-K. This filing is -0.11pp more bearish than last year's.
Why YoY instead of absolute: the LM lexicon has ~6.6× more negative words than positive (legal/risk-disclosure language is heavy on hedging), so every 10-K reads bearish on raw tone. Year-over-year change strips that bias and surfaces the actual shift in management's framing.

The two components the gauge averages: how Risk Factors and MD&A each shifted in net tone versus last year's 10-K. The headline above is their average, so a green needle over a soft section just means the other section carried it.

During the year ended December 31, 2025, we have withdrawn $27,249 of the interest earned on the Trust Account to pay income taxes and $335,538 in connection with the redemption of shares.
We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (less income taxes payable), to complete our Business Combination. To the extent that our capital stock or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.
As of December 31, 2025, we had cash of $11,909 held outside the Trust Account for general working capital purposes. In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of our officers and directors or their affiliates may, but are not obligated to, loan us funds as may be required. If we complete a Business Combination, we would repay such loaned amounts. Ins the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from our Trust Account would be used for such repayment.

If our estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our business prior to our Business Combination. Moreover, we may need to obtain additional financing either to complete our Business Combination or because we become obligated to redeem a significant number of our Public Shares upon consummation of our Business Combination, in which case we may issue additional securities or incur debt in connection with such Business Combination.
Going Concern
In connection with the Company’s assessment of going concern considerations in accordance with Financial Accounting Standard Board (“FASB”) Accounting Standards Update (“ASU”) 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company has until November 16, 2026 to consummate the proposed Business Combination, provided that the Company deposits into the Trust Account an amount equal to $0.10 per outstanding Public Share for each three-month extension commencing on November 17, 2023. It is uncertain that the Company will be able to consummate the proposed Business Combination by this time. If a Business Combination is not consummated by this date, there will be a mandatory liquidation and subsequent dissolution of the Company. Management has determined that the liquidity condition and mandatory liquidation, should a Business Combination not occur, and potential subsequent dissolution, raise substantial doubt about the Company’s ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after November 16, 2026. The Company intends to complete the proposed Business Combination before the mandatory liquidation date. However, there can be no assurance that the Company will be able to consummate any Business Combination by November 16, 2026.
Off-Balance Sheet Financing Arrangements
We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of December 31, 2025. We do not participate in transactions that create relationships with unconsolidated entities or financial partnerships, often referred to as variable interest entities, which would have been established for the purpose of facilitating off-balance sheet arrangements. We have not entered into any off-balance sheet financing arrangements, established any special purpose entities, guaranteed any debt or commitments of other entities, or purchased any non-financial assets.
Contractual Obligations
We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than an agreement to pay an affiliates, or advisors a total of up to $10,000 per month for office space, utilities, out of pocket expenses, and secretarial and administrative support. The arrangement will terminate upon the earlier of the Company’s consummation of a Business Combination or its liquidation.
The underwriters are entitled to a deferred fee of $0.30 per unit, or $2,070,000 in the aggregate will be payable to the underwriters for deferred underwriting commissions. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that the Company completes a Business Combination, subject to the terms of the underwriting agreement.
Critical Accounting Policies and Estimates
Critical Accounting Estimates
Use of Estimates
The preparation of financial statements and related disclosures in conformity with accounting principles generally accepted in the United States of America requires management to make estimates and assumptions that affect the reported amounts of assets and liabilities, disclosure of contingent assets and liabilities at the date of the financial statements, and income and expenses during the periods reported. Actual results could materially differ from those estimates. As of the end of the reporting period, we have not identified any critical accounting estimates.
Critical Accounting Policies
Common Stock Subject to Possible Redemption
We account for our Common Stock subject to possible redemption in accordance with the guidance in Accounting Standards Codification (“ASC”) Topic 480 “Distinguishing Liabilities from Equity.” Common stock subject to mandatory redemption is classified as a liability instrument and is measured at fair value. Conditionally redeemable Common Stock (including Common Stock that features redemption rights that are either within the control of the holder or subject to redemption upon the occurrence of uncertain events not solely within our control) is classified as temporary equity. At all other times, Common Stock is classified as stockholders’ equity. Our Common Stock features certain redemption rights that are considered to be outside of our control and subject to occurrence of uncertain future events. Accordingly, the Common Stock subject to possible redemption is presented as temporary equity, outside of the stockholders’ equity section of our balance sheets.
Net Loss per Common Share
We comply with accounting and disclosure requirements of Financial Accounting Standards Board (“FASB”) ASC 260, Earnings Per Share. The statement of operations include a presentation of loss per redeemable public share and loss per non-redeemable share following the two-class method of loss per share. In order to determine the net loss attributable to both the public redeemable shares and non-redeemable shares, we first considered the total loss allocable to both sets of shares. This is calculated using the total net loss less any dividends paid. For purposes of calculating net loss per share, any remeasurement of the accretion to redemption value of the common shares subject to possible redemption was considered to be dividends paid to our public stockholders. Subsequent to calculating the total loss allocable to both sets of shares, we split the amount to be allocated using a ratio of 3% for the Public Shares and 97% for the non-redeemable shares for the period ended December 31, 2025 and 16% for the redeemable Public Shares and 84% for the non-redeemable shares for the period ended December 31, 2024, reflective of the respective participation rights.
As of December 31, 2025, the Company did not have any dilutive securities and other contracts that could, potentially, be exercised or converted into common shares and then share in our earnings. As a result, diluted loss per share is the same as basic loss per share for the periods presented.
Recent Accounting Pronouncements
In December 2023, the FASB issued ASU 2023-09, Income Taxes (Topic 740): Improvements to Income Tax Disclosures (ASU 2023-09), which requires disclosure of incremental income tax information within the rate reconciliation and expanded disclosures of income taxes paid, among other disclosure requirements. ASU 2023-09 is effective for public business entities for fiscal years beginning after December 15, 2024 and for all other entities after December 15, 2025. Early adoption is permitted. The Company’s management is currently assessing the effect that adoption of this guidance will have on its financial statements and disclosures.
In November 2024, the FASB issued ASU 2024-03 and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Topic 220-40): Disaggregation of Income Statement Expenses (ASU 2025-01). The guidance requires disclosures about specific expense categories, including but not limited to, purchases of inventory, employee compensation, depreciation, amortization and selling expenses. The ASU is effective in the first annual reporting period beginning after December 15, 2026, and for interim periods within annual reporting periods beginning after December 15, 2027. The Company’s management is currently assessing the effect that adoption of this guidance will have on its financial statements and disclosures.
Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on our financial statements
