NOTE 1 — DESCRIPTION OF ORGANIZATION AND BUSINESS OPERATIONS

Archimedes Tech SPAC Partners II Co. (the “Company”) is a blank check company newly incorporated in the Cayman Islands on June 7, 2024. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, recapitalization, reorganization or other similar business combination with one or more businesses (the “Business Combination”). The Company has not selected any Business Combination target.

Although the Company may acquire a business in any industry, it intends to focus on companies engaged in the technology industry. The Company is an early stage and emerging growth company, and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of December 31, 2025, the Company has three subsidiaries, ATII Merger Sub Inc., a Delaware corporation and a direct, wholly owned subsidiary of the Company incorporated on December 4, 2025, ATII Merger Sub II, LLC, a Delaware limited liability company and a direct, wholly owned subsidiary of the Company incorporated on December 11, 2025, and ATII Holdings Inc. (“Holdings”), a Delaware corporation and a direct, wholly owned subsidiary of the Company incorporated on December 4, 2025. Holdings was formed for the purpose of merging with the Company to facilitate the consummation of the Business Combination. As of December 31, 2025, ATII Merger Sub Inc. and ATII Merger Sub II, LLC are inactive and have not commenced operations, and have no material assets, liabilities, revenues, or expenses attributable to these subsidiaries during the period.

As of December 31, 2025, the Company had not commenced any operations. All activity for the period from June 7, 2024 (inception) through December 31, 2025 relates to the Company’s formation and the initial public offering (“Initial Public Offering”), which is described below, and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering.

The registration statement for the Company’s Initial Public Offering was declared effective on February 10, 2025. On February 12, 2025, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the ordinary shares included in the Units being offered, the “Public Shares”), which included the full exercise by the underwriters of their over-allotment option in the amount of 3,000,000 Units, at $10.00 per Unit, generating gross proceeds of $230,000,000. Each Unit consists of one ordinary share, par value $0.0001 per share, and one-half of one redeemable warrant (the “Public Warrants”), each whole Public Warrant entitling the holder thereof to purchase one ordinary share at an exercise price of $11.50 per share, subject to adjustment.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 840,000 units (the “Private Placement Units”) at a price of $10.00 per Private Placement Unit in a private placement to Archimedes Tech SPAC Sponsors II LLC (the “Sponsor”) and BTIG, LLC, the representative of the underwriters in the Initial Public Offering (“BTIG”), generating gross proceeds of $8,400,000. Each Private Placement Unit consists of one ordinary share and one-half of one redeemable warrant (“Private Placement Warrants”), with each whole Private Placement Warrant entitling the holder to purchase one ordinary share at a price of $11.50 per share, subject to adjustment.

Transaction costs amounted to $13,175,520, consisting of $4,600,000 of cash underwriting fee, $8,050,000 of deferred underwriting fee and $525,520 of other offering costs.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering and the sale of Private Placement Units, although substantially all of the net proceeds are intended to be applied generally toward consummating a Business Combination. There is no assurance that the Company will be able to complete a Business Combination successfully. The Company must complete one or more initial Business Combinations with one or more operating businesses or assets with a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding any deferred underwriting fees and taxes payable on the interest earned on the Trust Account) at the time of the agreement to enter into the initial business combination. The Company will only complete a Business Combination if the post-transaction company owns or acquires 50% or more of the outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”).

Following the closing of the Initial Public Offering, on February 12, 2025, an amount of $231,150,000 ($10.05 per Unit) from the net proceeds of the sale of the Units and the sale of the Private Placement Units was held in a trust account (“Trust Account”), located in the United States and invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations and/or held as cash or cash items (including in demand deposit accounts). The Company will not be permitted to withdraw any of the principal or interest held in the Trust Account except for the withdrawal of interest to pay taxes. The funds held in the Trust Account will not otherwise be released from the Trust Account until the earliest of: (1) the completion of an initial Business Combination; (2) the redemption of any Public Shares properly submitted in connection with a shareholder vote to amend the Company’s amended and restated memorandum and articles of association (A) to modify the substance or timing of the Company’s obligation to allow redemption in connection with initial Business Combination or to redeem 100% of the Public Shares if the Company does not complete the initial Business Combination within the completion window, as defined below, or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity; and (3) the redemption of the Public Shares if the Company has not completed an initial Business Combination within the completion window, subject to Cayman Islands laws.

The Company will provide the holders of the outstanding Public Shares (the “Public Shareholders”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then in the Trust Account (initially anticipated to be $10.05 per Public Share, plus any pro rata interest then in the Trust Account, net of funds withdrawn to pay taxes). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s warrants. The Public Shares subject to possible redemption were recorded at a redemption value and classified as temporary equity upon the completion of the Initial Public Offering in accordance with the Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

The Company’s amended and restated memorandum and articles of association does not provide a specified maximum redemption threshold, except that in no event will the Company redeem its Public Shares in an amount that would cause its net tangible assets to be less than any net tangible asset or cash requirement that may be contained in the agreement relating to the initial Business Combination. As a result, the Company may be able to complete its initial Business Combination even though a substantial majority of the public shareholders do not agree with the transaction and have redeemed their shares or, if the Company seeks shareholder approval of the initial Business Combination and does not conduct redemptions in connection with the initial Business Combination pursuant to the tender offer rules, have entered into privately negotiated agreements to sell their shares to the initial shareholders, directors, officers, advisors or any of their respective affiliates. In the event the aggregate cash consideration the Company would be required to pay for all public shares that are validly submitted for redemption plus any amount required to satisfy cash conditions pursuant to the terms of the proposed Business Combination exceed the aggregate amount of cash available to the Company, the Company will not complete the Business Combination or redeem any shares, and all ordinary shares submitted for redemption will be returned to the holders thereof, and the Company instead may search for an alternate Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s amended and restated memorandum and articles of association provide that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares, without the prior consent of the Company.

The initial shareholders and the Company’s officers and directors entered into a letter agreement, pursuant to which they have agreed to waive: (1) their redemption rights with respect to any shares held by them in connection with the completion of the initial Business Combination; (2) their redemption rights with respect to any shares held by them in connection with a shareholder vote to amend the amended and restated memorandum and articles of association (A) to 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 Completion Window (as defined below) or (B) with respect to any other material provisions relating to shareholders’ rights or pre-initial business combination activity; and (3) their rights to liquidating distributions from the Trust Account with respect to any founder shares and private shares they hold if the Company fails to complete its initial Business Combination within the Completion Window as a result of a shareholder vote to amend the amended and restated memorandum and articles of association (although they will be entitled to liquidating distributions from the Trust Account with respect to any public shares they hold if the Company fails to complete the initial Business Combination within the Completion Window). If the Company submits its initial Business Combination to the public shareholders for a vote, the initial shareholders, directors and officers have agreed (and their permitted transferees will agree), pursuant to the terms of a letter agreement entered into with the Company, to vote any shares held by them in favor of the initial Business Combination.

The underwriters have agreed to waive their rights to their deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Completion Window and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the Initial Public Offering price per Unit ($10.00).

The Company will have until 21 months from the closing of the Initial Public Offering, or until such earlier liquidation date as the Company’s board of directors may approve, to complete a Business Combination (the “Completion Window”). If the Company has not completed a Business Combination within the Completion Window, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but not more than ten business days thereafter, redeem the public shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account (net of funds withdrawn to pay taxes and up to $100,000 of interest to pay dissolution expenses), 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), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject, in each case, to obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. There is no limitation on the Company’s ability to raise funds privately or through loans in connection with its initial Business Combination.

In order to protect the amounts held in the Trust Account, the Sponsor has agreed to be liable to the Company if and to the extent any claims by a third party (other than the independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.05 per public share or (2) such lesser amount per public share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of the trust assets, in each case net of interest which may be withdrawn to pay taxes, except as to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account and except as to any claims under the Company’s indemnity of the underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (except for the Company’s independent registered public accounting firm), prospective target businesses and other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Liquidity and Capital Resources

As of December 31, 2025, the Company had cash of $1,362,766. The Company intends to use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor, or certain of the Company’s officers and directors or their affiliates may, but are not obligated to, loan the Company funds as may be required. If the Company completes a Business Combination, the Company would repay such loaned amounts. In the event that a Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay such loaned amounts but no proceeds from the Trust Account would be used for such repayment. Up to $1,500,000 of such loans may be convertible into units, at a price of $10.00 per unit, at the option of the lender. The units would be identical to the Private Placement Units.

In connection with the Company’s assessment of going concern considerations in accordance with FASB ASC 2014-15, “Disclosures of Uncertainties about an Entity’s Ability to Continue as a Going Concern,” the Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. Management has determined that the Company has sufficient funds to finance the working capital needs of the Company within one year from the date of issuance of the financial statement. However, if the Company is unable to complete an Initial Business Combination by November 12, 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 plans to consummate an Initial Business Combination prior to the mandatory liquidation date. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after November 12, 2026.
