**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**MARCH 31, 2026**

**(UNAUDITED)**

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

Archimedes Tech SPAC Partners II Co. (the "Company" or "ATII") 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. 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 March 31, 2026, the Company has three subsidiaries, ATII Merger Sub Inc. ("Merger Sub I"), a Delaware corporation and a direct, wholly owned subsidiary of the Company incorporated on December 4, 2025, ATII Merger Sub II, LLC ("Merger Sub II"), a Delaware limited liability company and a direct, wholly owned subsidiary of the Company formed on December 11, 2025, and ATII Holdings Inc. ("Pubco"), a Delaware corporation and a direct, wholly owned subsidiary of the Company incorporated on December 4, 2025. Merger Sub I, Merger Sub II and Pubco were formed for the purpose of facilitating the Business Combination (as defined below). As of March 31, 2026, Merger Sub I, Merger Sub II and Pubco 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 March 31, 2026, the Company had not commenced any operations. All activity for the period from June 7, 2024 (inception) through March 31, 2026 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 and negotiating for an initial 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 an initial business combination. There is no assurance that the Company will be able to complete an initial 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 an initial 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.

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS**

**MARCH 31, 2026**

**(UNAUDITED)**

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 an initial 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 an initial 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 an initial 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 an initial 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 an initial 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 an initial business combination (the "Completion Window"). If the Company has not completed an initial 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.

**Merger Agreement**

On April 20, 2026, the Company, Pubco, Merger Sub I, Merger Sub II, and Forge Nano, Inc., a Delaware corporation ("Forge Nano"), entered into a merger agreement (the "Merger Agreement"). Pursuant to the Merger Agreement, and subject to the terms and conditions set forth therein, the Company will re-domicile and become a Delaware corporation by merging with Pubco (the "Reincorporation"), following which the separate corporate existence of the Company will cease and Pubco will continue as the surviving corporation. At the effective time of the Reincorporation, Pubco will adopt Delaware organizational documents, which will provide, among other things, that the name of Pubco will be changed to "Forge Nano Holdings Inc."

At least one day following the effective time of the Reincorporation, Merger Sub I will merge with and into Forge Nano (the "First Company Merger"), with Forge Nano surviving (the "Initial Surviving Corporation") and as a result of which the holders of the issued and outstanding capital stock of Forge Nano will receive shares of Pubco common stock in exchange for the issued and outstanding capital stock of Forge Nano. As a result of the First Company Merger, Forge Nano will become a wholly-owned subsidiary of Pubco.

At the effective time of the First Company Merger: (i) each share of each class of preferred stock of Forge Nano will be converted into shares of common stock of Forge Nano pursuant to Forge Nano's organizational documents; (ii) each share of Forge Nano common stock (including shares of Forge Nano common stock issued upon conversion of the shares of Forge Nano preferred stock) will be cancelled and automatically converted into the right to receive, without interest, the applicable pro rata portion of the Closing Payment Shares (as defined below) for such number of shares of Forge Nano Common Stock; (iii) each outstanding warrant of Forge Nano will be assumed by Pubco and become a corresponding Pubco warrant (the "Pubco Forge Nano Warrants"), subject to the same terms and conditions (including vesting and exercisability) as were applicable to the corresponding Forge Nano warrant; and (iv) each option or other right to acquire securities of Forge Nano and/or its affiliates held by Ascent Funds International Management LLC (together with the Forge Nano warrants, the "Forge Nano Convertible Securities"), will be cancelled and converted into one warrant to purchase shares of Pubco common stock (together with the Pubco Forge Nano Warrants, the "Pubco Convertible Securities"). Under the Merger Agreement, "Closing Payment Shares" means such number of shares of Pubco common stock equal to (a)(i) $1,200,000,000 *divided by* (ii) $10.00 *minus* (b) the Pubco common stock issuable upon exercise of any Pubco Convertible Securities issued in exchange for Forge Nano Convertible Securities, if any.

At the effective time of the First Company Merger, each option to purchase shares of Forge Nano common stock will be converted into an option to purchase shares of Pubco common stock on substantially the same terms and conditions, including with respect to vesting and termination-related provisions (as applicable).

**(UNAUDITED)**

Pursuant to the terms of the Merger Agreement, and subject to the terms and conditions set forth therein, the Forge Nano stockholders who receive Closing Payment Shares and the holders of Pubco Convertible Securities issued in exchange for Forge Nano Convertible Securities, if any, will be entitled to receive, a proportional amount of up to an aggregate of 90,000,000 additional shares of Pubco common stock, issuable upon achievement of certain milestones during the five (5) year period following the closing date. The earn-out shares will be issued at or prior to the closing to the escrow agent and will be disbursed therefrom upon achievement of the applicable milestones. The earn-out shares attributable to holders of Pubco Convertible Securities issued in exchange for Forge Nano Convertible Securities, if any, pursuant to the Merger Agreement will only be disbursed by the escrow agent if an applicable milestone is achieved upon the exercise, conversion or settlement thereof in accordance with their terms.

Immediately following the effective time of the First Company Merger, the Initial Surviving Corporation will merge with and into Merger Sub II (the "Second Company Merger" and together with the First Company Merger and the Reincorporation, the "Business Combination"), with Merger Sub II surviving and Pubco acquiring one membership interest in surviving company and such membership interest will constitute the only outstanding equity of the surviving company.

The Merger Agreement contains customary representations, warranties and covenants of the parties thereto. The consummation of the proposed transactions is subject to certain conditions as further described in the Merger Agreement.

Concurrently with their entry into the Merger Agreement, ATII and Forge Nano entered into a support agreement (the "Purchaser Sponsor Agreement") with the Sponsor, pursuant to which the Sponsor agreed, among other things, (i) to vote in favor of the approval and adoption of the Merger Agreement and the Business Combination, (ii) to not redeem, sell or tender, during the term of the Purchaser Support Agreement, any ordinary shares of the Company owned by the Sponsor in connection with the Business Combination and (iii) to not transfer any ordinary shares of the Company held by the Sponsor in accordance with the lock-up provisions set forth in ATII's final prospectus filed with the SEC on February 11, 2025.

Pursuant to the Purchaser Support Agreement, and subject to the terms and conditions set forth therein, the Sponsor also agreed to contribute up to 3,300,000 ordinary shares, together with all shares of Pubco common stock issued upon conversion thereof, including any securities paid as dividends or distributions with respect to or into which such shares are exchanged or converted (the "Contribution Shares") to secure one or more financing transactions in connection with the Business Combination. Any Contribution Shares not used to secure financing transactions will be retained by the Sponsor.

In connection with their entry into the Merger Agreement, ATII and Forge Nano entered into a lock-up agreement (the "Lock-Up Agreement") with certain stockholders of Forge Nano. Pursuant to the Lock-Up Agreement, such Forge Nano stockholders agreed that they will not, during the Lock-Up Period (as defined below), directly or indirectly sell, exchange, assign, transfer (including by merger, conversion or operation of law), gift or otherwise dispose, any of the shares received as merger consideration, or make a public announcement of any intention to effect such a transfer. As used herein, "Lock-Up Period" means the period commencing on the closing date of the Business Combination and ending on the earlier of: (i) six months after the closing; and (ii) the date on which the last reported sale price of the Pubco common stock equals or exceeds $12.00 per share for any 20 trading days within any 30 trading day period after the closing.

At the closing, ATII, the Sponsor and certain stockholders of Forge Nano (collectively, the "Subject Parties") will enter into a registration rights agreement (the "Registration Rights Agreement"), pursuant to which, among other things, Pubco will be obligated to file a registration statement on Form S-1 with the SEC as soon as practicable but no later than 30 calendar days following the closing of the Business Combination to register the resale of certain securities of Pubco held by the Subject Parties, subject to customary liquidated damages in the event Pubco is unable to meet the filing deadline. The Registration Rights Agreement will also provide the Subject Parties with "piggy-back" registration rights, subject to certain requirements and customary conditions. All expenses of registration under the Registration Rights Agreement, including the legal fees of one firm of counsel chosen by stockholders participating in a registration, will be paid by Pubco.

In connection with the execution of the Merger Agreement, ATII, Pubco and Forge Nano entered into a subscription agreement (the "Subscription Agreement") with an accredited investor, pursuant to which Pubco will, substantially concurrently with, and contingent upon, the consummation of the Business Combination, sell an aggregate of 10,000,000 shares of Pubco common stock and warrants to purchase an aggregate of 15,000,000 shares of Pubco common stock to such investor, each with an exercise price of $10.00 (subject to adjustments) for an aggregate purchase price of $100,000,000.

For additional information on the Business Combination, please see the Company's 8-K filed with the SEC on April 20, 2026, and the Form S-4 filed with the SEC on May 5, 2026.

**Liquidity and Capital Resources**

As of March 31, 2026, the Company had cash of $1,077,839. 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 an initial business combination.

In order to fund working capital deficiencies or finance transaction costs in connection with an initial 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 an initial business combination, the Company would repay such loaned amounts. In the event that an initial 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.

**(UNAUDITED)**

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 an initial 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.

**NOTE 2** — **SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES**

**Basis of Presentation**

The accompanying unaudited condensed consolidated financial statements have been prepared in accordance with accounting principles generally accepted in the United States of America ("GAAP") for interim financial information and in accordance with the instructions to Form 10-Q and Article 8 of Regulation S-X of the SEC. Certain information or footnote disclosures normally included in unaudited condensed consolidated financial statements prepared in accordance with GAAP have been condensed or omitted, pursuant to the rules and regulations of the SEC for interim financial reporting. Accordingly, they do not include all the information and footnotes necessary for a complete presentation of financial position, results of operations, or cash flows. In the opinion of management, the accompanying unaudited condensed consolidated financial statements include all adjustments, consisting of a normal recurring nature, which are necessary for a fair presentation of the financial position, operating results and cash flows for the periods presented.

The accompanying unaudited condensed consolidated financial statements should be read in conjunction with the Company's Annual Report on Form 10-K filed with the SEC on March 4, 2026. The interim results for the three months ended March 31, 2026 are not necessarily indicative of the results to be expected for the year ending December 31, 2026 or for any future periods.

**Principles of Consolidation**

The accompanying unaudited condensed consolidated financial statements include the accounts of the Company and its subsidiaries. All intercompany transactions were eliminated in the unaudited condensed consolidated financial statements.

**Emerging Growth Company**

The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act, as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act"), and it may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the independent registered public accounting firm attestation requirements of Section 404 of the Sarbanes-Oxley Act, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a nonbinding advisory vote on executive compensation and 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. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's unaudited condensed consolidated 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.

**MARCH 31, 2026**

**(UNAUDITED)**

**Use of Estimates**

The preparation of the unaudited condensed consolidated financial statements in conformity with U.S. 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 unaudited condensed consolidated financial statements and the reported amounts of other income and 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 unaudited condensed consolidated 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 $1,077,839 and $1,362,766 in cash as of March 31, 2026 and December 31, 2025, respectively, and no cash equivalents as of such dates.

**Demand Deposit Held in Trust Account**

As of March 31, 2026 and December 31, 2025, the assets held in Trust Account, amounting to $242,002,931 and $239,860,969, respectively, were held in demand deposit accounts.

**Concentration of Credit Risk**

Financial instruments that potentially subject the Company to concentration of credit risk consist of a cash account in a financial institution, which, at times may exceed the Federal Depository 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**

The Company complies with the requirements of the ASC 340-10-S99 and SEC Staff Accounting Bulletin ("SAB") Topic 5A — "Expenses of Offering". Offering costs consist principally of professional and registration fees that are related to the Initial 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. The Company applies this guidance to allocate Initial Public Offering proceeds from the Units between ordinary shares and warrants, using the residual method by allocating Initial Public Offering proceeds first to assigned value of the warrants and then to the ordinary shares. Offering costs allocated to the Public Shares were charged to temporary equity, and offering costs allocated to the Public Warrants and Private Placement Units were charged to shareholders' deficit as the warrants associated with units issued in the Initial Public Offering and Private Placement, after management's evaluation, are accounted for under equity treatment.

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.

**Income Taxes**

The Company 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 condensed consolidated 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. The Company's 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 March 31, 2026 and December 31, 2025, 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.

**Net Income per Ordinary Share**

The Company complies with the accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share". Net income per ordinary share is computed by dividing net income by the weighted average number of ordinary shares outstanding for the period. Accretion associated with the redeemable ordinary shares is excluded from earnings per share as the redemption value approximates fair value.

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS** 

**MARCH 31, 2026**

**(UNAUDITED)**

The calculation of diluted net income per share does not consider the effect of the warrants issued in connection with the (i) Initial Public Offering, and (ii) the private placement, since the exercise of the warrants are contingent upon the occurrence of future events. For the three months ended March 31, 2026 and 2025, the warrants are exercisable to purchase 11,920,000 ordinary shares. The weighted average of these shares was excluded from the calculation of diluted net income per ordinary share since the inclusion of such warrants would be anti-dilutive. The warrants cannot be converted to ordinary shares prior to an initial business combination; therefore, they have been classified as anti-dilutive.

**Fair Value of Financial Instruments**

The fair value of the Company's assets and liabilities, which qualify as financial instruments under ASC 820, "Fair Value Measurement," approximates the carrying amounts represented in the condensed consolidated balance sheets, primarily due to their short-term nature.

**Fair Value Measurement**

The fair value of the Company's financial assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities). The following fair value hierarchy is used to classify assets and liabilities based on the observable inputs and unobservable inputs used in order to value the assets and liabilities:

---

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

---

---

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

---

---

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

---

**Warrant Instruments**

The Company accounted for the Public and Private Placement 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", whereby under that provision, the warrants that do not meet the criteria for equity treatment must be recorded as liability. Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values.

------

[**Table of Contents**](#toc)

**ARCHIMEDES TECH SPAC PARTNERS II CO.**

**NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS** 

**MARCH 31, 2026**

**(UNAUDITED)**

The fair value of the Public Warrants on the closing of the Initial Public Offering on February 12, 2025, was $1,725,000, or $0.15 per Public Warrant. The fair value of Public Warrants was determined using Monte Carlo Simulation Model. 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 level 3 valuation of the Public Warrants:

---

| | |
|:---|:---|
|  | **February 12,**<br> **2025** |
| Implied ordinary share price | $9.93 |
| Exercise price | $11.50 |
| Simulation term (years) | 6.5 |
| Risk-free rate (continuous) | 4.49% |
| Selected volatility | 3.0% |
| Calculated value per warrant | $0.15 |
| Probability of de-SPAC and market adjustment | 11.0% |

---

**Ordinary Shares Subject to Possible Redemption**

The public shares contain a redemption feature which 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 Company's initial business combination. In accordance with ASC 480-10-S99, the Company classifies public shares subject to possible 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 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 amount value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of March 31, 2026 and December 31, 2025, the ordinary shares subject to possible redemption are presented at redemption value as temporary equity, outside of the shareholders' deficit section of the Company's condensed consolidated balance sheets. As of March 31, 2026 and December 31, 2025, the ordinary shares subject to possible redemption reflected in the condensed consolidated balance sheets are reconciled in the following table:

---

| | |
|:---|:---|
| Gross proceeds | $230000000 |
| Less: |  |
| Proceeds allocated to Public Warrants | (1725000) |
| Ordinary shares issuance costs | (13058326) |
| Plus: |  |
| Accretion of carrying value to redemption value | 24644295 |
| Ordinary shares subject to possible redemption, December 31, 2025 | $239860969 |

| Accretion of carrying value to redemption value | 2141962 |
| Ordinary shares subject to possible redemption, March 31, 2026 | $242002931 |

**Recent Accounting Standards**

Management does not believe that any recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company's unaudited condensed consolidated financial statements.

**NOTE 3** — **INITIAL PUBLIC OFFERING**

Pursuant to the Initial Public Offering, the Company sold 23,000,000 Units, which included a full exercise by the underwriters of their over-allotment option of 3,000,000 Units, at a price of $10.00 per Unit. Each Unit consists of one ordinary share and one-half Public Warrant. Each whole Public Warrant entitles the holder to purchase one ordinary share at a price of $11.50 per share, subject to adjustment (Note 7).

**NOTE 4** — **PRIVATE PLACEMENT**

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 840,000 Private Placement Units at a price of $10.00 per Private Placement Unit in a private placement to the Sponsor and BTIG, generating gross proceeds of $8,400,000. Each Private Placement Unit consists of one ordinary share and one-half of one redeemable warrant (the "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 (Note 7). The proceeds from the sale of the Private Placement Units are added to the net proceeds from the Initial Public Offering held in the Trust Account. If the Company does not complete an initial business combination within the Completion Window, the proceeds from the sale of the Private Placement Units held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

**NOTE 5** — **RELATED PARTIES**

**Founder Shares**

On June 7, 2024, the Sponsor made a capital contribution of $25,000 to cover certain of the Company's expenses, for which the Company issued 5,750,000 ordinary shares (the "Founder Shares"). The Founder Shares include an aggregate of up to 750,000 shares subject to surrender and forfeiture to the extent that the underwriters' over-allotment is not exercised in full or in part, so that the number of Founder Shares will equal, on an as-converted basis, approximately 20% of the Company's issued and outstanding ordinary shares after the Initial Public Offering. As a result of the Initial Public Offering and the full exercise by the underwriters of their over-allotment option, 750,000 shares are no longer subject to surrender and forfeiture.

Pursuant to a letter agreement that the initial shareholders, directors and officers have entered into with the Company, with certain limited exceptions, the Founder Shares are not transferable, assignable or salable (except to directors and officers and other persons or entities affiliated with the initial shareholders, each of whom will be subject to the same transfer restrictions) until the earlier of: (i) six months after the completion of the initial business combination; and (ii) subsequent to the initial business combination, 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 ordinary shares for cash, securities or other property. Notwithstanding the foregoing, the Founder Shares will be released from the lock-up if (1) the last reported sale price of the Company's ordinary shares equals or exceeds $12.00 per share (as adjusted for share splits, share capitalizations, reorganizations, recapitalizations and other similar transactions) for any 20 trading days within any 30-trading day period after the initial business combination or (2) if the Company completes a transaction after the initial business combination which results in all of the Company's shareholders having the right to exchange their shares for cash, securities or other property.

**Promissory Note** — **Related Party**

On June 7, 2024, the Sponsor issued an unsecured promissory note to the Company (as amended, the "Promissory Note"), pursuant to which the Company may borrow up to an aggregate principal amount of $290,000. The Promissory Note was non-interest bearing and payable on the earlier of (i) March 31, 2025 or (ii) the consummation of the Initial Public Offering or (iii) the date on which the Company determines to not proceed with the Initial Public Offering. Simultaneously with the closing of the Initial Public Offering on February 12, 2025, the Company repaid the outstanding borrowings under the Promissory Note amounting to $290,000. Borrowings under the note are no longer available.

**Due to Related Party**

Due to related party represents recurring Company expenses advanced by officers on behalf of the Company. As of March 31, 2026 and December 31, 2025, the Company owed $4,283 and $1,239 to officers, respectively.

**Administrative Support Agreement**

Commencing on the effective date, February 10, 2025, the Company agreed to reimburse the Sponsor in an amount equal to $10,000 per month for office space, administrative and support services. Upon completion of the initial business combination or the Company's liquidation, the Company will cease paying these monthly fees. For the three months ended March 31, 2026, the Company incurred and paid $30,000 in fees for these services. For the three months ended March 31, 2025, the Company incurred and accrued $16,786 in fees for these services.

**Working Capital Loans**

In order to finance transaction costs in connection with an initial business combination, the Sponsor or an affiliate of the Sponsor, or certain of the Company's officers and directors may, but are not obligated to, loan the Company funds as may be required (the "Working Capital Loans"). If the Company completes an initial business combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that an 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. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. The Working Capital Loans would either be repaid upon consummation of an initial business combination, without interest, or, at the lender's discretion, 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. The units would be identical to the Private Placement Units. As of March 31, 2026 and December 31, 2025, no Working Capital Loans were outstanding.

**NOTE 6** — **COMMITMENTS AND CONTINGENCIES**

**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.

Any of the above-mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from ongoing global conflicts and/or other future global conflicts and subsequent sanctions or related actions, could adversely affect the Company's search for an initial business combination and any target business with which the Company may ultimately consummate an initial business combination.

**Registration Rights**

The holders of the Founder Shares, Private Placement Units (and underlying securities) and any units (and underlying securities) that may be issued on conversion of Working Capital Loans are entitled to registration rights pursuant to a registration rights agreement requiring the Company to register such securities for resale. 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. However, the registration rights agreement provides that the Company will not be required to effect or permit any registration or cause any registration statement to become effective until termination of the applicable lock-up period. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

**Underwriting Agreement**

The Company granted the underwriters a 45-day option from the date of Initial Public Offering to purchase up to 3,000,000 additional Units to cover over-allotments, if any, at the Initial Public Offering price less the underwriting discounts and commissions. On February 12, 2025, simultaneously with the Initial Public Offering, the underwriters exercised their over-allotment option in full, closing on the 3,000,000 additional Units.

The underwriters were paid a cash underwriting discount of $0.20 per Unit, or $4,600,000 in the aggregate upon the closing of the Initial Public Offering. In addition, the underwriters are entitled to a deferred fee of $0.35 per Unit, or $8,050,000 in the aggregate. 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 an initial business combination, subject to the terms of the underwriting agreement.

**NOTE 7** — **SHAREHOLDERS**' **DEFICIT**

**Preference Shares** — The Company is authorized to issue 1,000,000 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 Company's board of directors. As of March 31, 2026 and December 31, 2025, there were no preference shares issued or outstanding.

**(UNAUDITED)**

**Ordinary Shares** — The Company is authorized to issue 400,000,000 ordinary shares with a par value of $0.0001 per share. Holders of ordinary shares are entitled to one vote for each share. As of March 31, 2026 and December 31, 2025, there were 6,590,000 ordinary shares issued and outstanding, excluding the 23,000,000 ordinary shares subject to possible redemption.

**Warrants** — As of March 31, 2026 and December 31, 2025, there were 11,920,000 warrants outstanding, including 11,500,000 Public Warrants and 420,000 Private Placement Warrants. Public Warrants may only be exercised for a whole number of shares. No fractional warrants will be issued upon separation of the Units and only whole warrants will trade. The Public Warrants will become exercisable on the later of (a) 30 days after the completion of an initial business combination and (b) 12 months from the closing of the Initial Public Offering. The Public Warrants will expire five years after the completion of an initial business combination or earlier upon redemption or liquidation.

The Company will not be obligated to deliver any ordinary shares pursuant to the exercise of a warrant and will have no obligation to settle such warrant exercise unless a registration statement under the Securities Act covering the issuance of the ordinary shares underlying the warrants is then effective and a prospectus relating thereto is current, subject to the Company satisfying its obligations with respect to registration. No warrant will be exercisable and the Company will not be obligated to issue ordinary shares upon exercise of a warrant unless ordinary shares issuable upon such warrant exercise has been registered, qualified or deemed to be exempt under the securities laws of the state of residence of the registered holder of the warrants.

The Company has agreed that as soon as practicable, but in no event later than twenty (20) business days after the closing of an initial business combination, it will use its best efforts to file with the SEC a registration statement covering the ordinary share issuable upon exercise of the warrants, to cause such registration statement to become effective and to maintain a current prospectus relating to those ordinary shares until the warrants expire or are redeemed, as specified in the warrant agreement. If a registration statement covering the ordinary shares issuable upon exercise of the warrants is not effective by the 60th business day after the closing of an initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company will have failed to maintain an effective registration statement, exercise warrants on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act or another exemption. Notwithstanding the foregoing, if a registration statement covering the ordinary shares issuable upon exercise of the warrants is not effective within a specified period following the consummation of an initial business combination, warrant holders may, until such time as there is an effective registration statement and during any period when the Company shall have failed to maintain an effective registration statement, exercise warrants on a cashless basis pursuant to the exemption provided by Section 3(a)(9) of the Securities Act, provided that such exemption is available. If that exemption, or another exemption, is not available, holders will not be able to exercise their warrants on a cashless basis.

Once the warrants become exercisable, the Company may redeem the outstanding Public Warrants:

• in whole and not in part;

• at a price of $0.01 per Public Warrant;

• upon a minimum of 30 days' prior written notice of redemption, referred to as the 30-day redemption peiod; and

• if, and only if, the last sale price of ordinary shares equals or exceeds $18.00 per share (as adjusted for share subdivisions, share consolidations, share capitalizations, rights issuances, 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.

If the Company calls the warrants for redemption, management will have the option to require all holders that wish to exercise warrants to do so on a "cashless basis." In determining whether to require all holders to exercise their warrants on a "cashless basis," management will consider, among other factors, the Company's cash position, the number of warrants that are outstanding and the dilutive effect on the Company's shareholders of issuing the maximum number of ordinary shares issuable upon the exercise of the Company's warrants. In such event, each holder would pay the exercise price by surrendering the warrants for that number of ordinary shares equal to the quotient obtained by dividing (x) the product of the number of ordinary shares underlying the warrants, multiplied by the excess of the "fair market value" over the exercise price of the warrants by (y) the fair market value. The "fair market value" shall mean the highest closing sale price of the ordinary share for the 10 trading days ending on the third trading day prior to the date on which the notice of redemption is sent to the holders of warrants.

In addition, if (x) the Company issues additional ordinary shares or equity-linked securities for capital raising purposes in connection with the closing of the initial business combination at a Newly Issued Price of less than $9.20 per ordinary shares (with such issue price or effective issue price to be determined in good faith by the board of directors and, in the case of any such issuance to the Sponsor or its affiliates, without taking into account any Founder Shares held by the Sponsor or such affiliates, as applicable, prior to such issuance), (y) the aggregate gross proceeds from such issuances represent more than 60% of the total equity proceeds, and interest thereon, available for the funding of the initial business combination on the date of the consummation of the initial business combination (net of redemptions), and (z) the Market Value is below $9.20 per share, then the exercise price of the warrants will be adjusted (to the nearest cent) to be equal to 115% of the higher of the Market Value and the Newly Issued Price, and the $18.00 per share redemption trigger price described above will be adjusted (to the nearest cent) to be equal to 180% of the higher of the Market Value and the Newly Issued Price.

The Private Placement Warrants will be identical to the Public Warrants underlying the Units being sold in the Initial Public Offering, subject to certain limited exceptions.

**NOTE 8** — **SEGMENT INFORMATION**

ASC Topic 280, "Segment Reporting," establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise 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 Company's 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 Executive 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 or loss that also is reported on the unaudited condensed consolidated statements of operations as net income or loss. The measure of segment assets is reported on the condensed consolidated 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 or loss and total assets, which include the following:

---

| | | |
|:---|:---|:---|
|  | **March 31,** | **December 31,** |
|  | **2026** | **2025** |
| Cash | $1077839 | $1362766 |
| Demand deposit held in Trust Account | $242002931 | $239860969 |

| Interest earned on cash in bank account | $11514 | $10790 |
| Interest earned on demand deposit held in Trust Account | $2141962 | $1305884 |

---

The CODM is provided with details of cash and liquid resources available with the Company. The CODM reviews the position of total assets available with the Company to assess if the Company has sufficient resources available to discharge its liabilities.

The CODM reviews interest earned on demand deposit 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 Trust Agreement.

Interest earned on cash in bank account and general and administrative expenses are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete an initial business combination or similar transaction within the Completion Window. The CODM also reviews the interest earned on cash in bank account and general and administrative expenses to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative expenses, as reported on the unaudited condensed consolidated statements of operations, are the significant segment expenses provided to the CODM on a regular basis.

The Company evaluated subsequent events and transactions that occurred after the consolidated balance sheet date up to the date that the unaudited condensed consolidated financial statements were issued. Based upon this review, other than as described below, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited condensed consolidated financial statements.

On April 20, 2026, the Company, Pubco, Merger Sub I, Merger Sub II and Forge Nano entered the Merger Agreement, pursuant to which and subject to the terms and conditions set forth therein, the Company will re-domicile and become a Delaware corporation by merging with Pubco, following which the separate corporate existence of the Company will cease and Pubco will continue as the surviving corporation.

**Overview**

We are a blank check company incorporated in the Cayman Islands on June 7, 2024 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. We intend to effectuate our initial business combination using cash derived from the proceeds of the Initial Public Offering and the sale of the Private Placement Units, our shares, debt or a combination of cash, shares and debt.

While we may pursue an initial business combination target in any business, industry or geographical location, we intend to focus our search for businesses in the technology industry, and our focus will be on the artificial intelligence, cloud services and automotive technology sectors. 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.

We expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure you that our plans to complete an initial business combination will be successful.

As of March 31, 2026, we have three subsidiaries, ATII Merger Sub Inc., a Delaware corporation and our direct, wholly owned subsidiary incorporated on December 4, 2025, ATII Merger Sub II, LLC, a Delaware limited liability company and our direct, wholly owned subsidiary formed on December 11, 2025, and ATII Holdings Inc., a Delaware corporation and our direct, wholly owned subsidiary incorporated on December 4, 2025. Merger Sub I, Merger Sub II and Pubco were formed for the purpose of facilitating the Business Combination. As of March 31, 2026, Merger Sub I, Merger Sub II and Pubco are inactive and have not commenced operations, and have no material assets, liabilities, revenues, or expenses attributable to these subsidiaries during the period.

The registration statement for our Initial Public Offering was declared effective on February 10, 2025. On February 12, 2025, we consummated our Initial Public Offering of 23,000,000 Units, including the exercise in full by the underwriters of an option to purchase up to 3,000,000 Units to cover over-allotments. Each Unit consists of one ordinary share and one-half of one Public Warrants, with each whole Public Warrant entitling the holder thereof to purchase one ordinary share for $11.50 per share (subject to adjustment). The Units were sold at an offering price of $10.00 per unit, generating gross proceeds of $230,000,000.

Simultaneously with the closing of the IPO, we consummated a private placement of an aggregate of 840,000 Private Placement Units to the Sponsor and BTIG, at a price of $10.00 per unit, generating total proceeds of $8,400,000. Of those 840,000 Private Placement Units, the Sponsor purchased 530,000 Private Placement Units and BTIG purchased 310,000 Private Placement Units. The Private Placement Units are identical to the Units sold in the IPO, except that the Private Placement Units, including the underlying securities, may not be transferable, assignable or salable by the Sponsor until the consummation of our initial business combination, subject to certain limited exceptions. The Sponsor and BTIG were granted certain demand and piggyback registration rights in connection with the purchase of the Private Placement Units. No underwriting discounts or commissions were paid with respect to such sale. The Private Placement Units were issued pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

------

[**Table of Contents**](#toc)

Following the closing of the IPO, a total of $231,150,000 of the net proceeds from the sale of Units in the IPO (including the over-allotment option Units) and the private placement of the Private Placement Units, were placed in a Trust Account established for the benefit of the Company's public shareholders with Odyssey Transfer and Trust Company acting as trustee. Except with respect to interest earned on the funds held in the Trust Account that may be released to us to pay our taxes, if any, the funds held in the Trust Account will not be released from the Trust Account until the earliest to occur of: (1) our completion of an initial business combination; (2) the redemption of any public shares properly submitted in connection with a shareholder vote to amend our amended and restated memorandum and articles of association (A) to modify 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 completion window or (B) with respect to any other material provisions relating to shareholders' rights or pre-initial business combination activity; and (3) the redemption of our public shares if we have not completed an initial business combination within the completion window, subject to applicable law. The funds in the Trust Account will be 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).

We will have up to 21 months from the closing of the IPO to consummate an initial business combination. We may hold a shareholder vote at any time to amend our amended and restated memorandum and articles of association to modify the amount of time we will have to consummate an initial business combination (as well as to modify the substance or timing of our obligation to redeem 100% of our public shares if we have not consummated an initial business combination within the prescribed time periods or with respect to any other material provisions relating to shareholders' rights or pre-initial business combination activity). Our Sponsor, executive officers and directors have agreed that they will not propose any such amendment 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 (net of funds withdrawn to pay our taxes), divided by the number of then issued and outstanding public shares, subject to certain limitations.

If we do not complete our initial business combination within the completion window, we 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 our taxes and up to $100,000 of interest to pay dissolution expenses), divided by the number of then issued and 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 our remaining shareholders and our board of directors, liquidate and dissolve, subject, in each case, to our obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

We will provide our public shareholders with the opportunity to redeem all or a portion of their public shares upon the completion of our initial business combination at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account calculated as of two business days prior to the consummation of the initial business combination, including interest (net of funds withdrawn to pay our taxes), divided by the number of then issued and outstanding public shares, subject to certain limitations. Our public shareholders will be permitted to redeem their shares regardless of whether they abstain, vote for, vote against, or vote at all with respect to the proposed business combination. There will be no redemption rights upon the completion of our initial business combination with respect to our warrants. Our Sponsor, directors and officers have entered into a letter agreement with us, pursuant to which they have agreed to waive their redemption rights with respect to any shares held by them in connection with the completion of our initial business combination.

If a shareholder vote on our initial business combination is not required by law and we do not decide to hold a shareholder vote for business or other legal reasons, we will offer to redeem our public shares pursuant to Rule 13e-4 and Regulation 14E under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and will file tender offer documents with the SEC prior to completing our initial business combination which contain substantially the same financial and other information about our initial business combination and the redemption rights as is required under Regulation 14A under the Exchange Act.

**Merger Agreement**

On April 20, 2026, the Company, Pubco, Merger Sub I, Merger Sub II, and Forge Nano, Inc., a Delaware corporation ("Forge Nano"), entered into a merger agreement (the "Merger Agreement"). Pursuant to the Merger Agreement, and subject to the terms and conditions set forth therein, the Company will re-domicile and become a Delaware corporation by merging with Pubco (the "Reincorporation"), following which the separate corporate existence of the Company will cease and Pubco will continue as the surviving corporation. At the effective time of the Reincorporation, Pubco will adopt Delaware organizational documents, which will provide, among other things, that the name of Pubco will be changed to "Forge Nano Holdings Inc."

At least one day following the effective time of the Reincorporation, Merger Sub I will merge with and into Forge Nano (the "First Company Merger"), with Forge Nano surviving (the "Initial Surviving Corporation") and as a result of which the holders of the issued and outstanding capital stock of Forge Nano will receive shares of Pubco common stock in exchange for the issued and outstanding capital stock of Forge Nano. As a result of the First Company Merger, Forge Nano will become a wholly-owned subsidiary of Pubco.

------

At the effective time of the First Company Merger: (i) each share of each class of preferred stock of Forge Nano will be converted into shares of common stock of Forge Nano pursuant to Forge Nano's organizational documents; (ii) each share of common stock of Forge Nano (including shares of Forge Nano common stock issued upon conversion of the shares of Forge Nano preferred stock) will be cancelled and automatically converted into the right to receive, without interest, the applicable pro rata portion of the Closing Payment Shares (as defined below) for such number of shares of Forge Nano Common Stock; (iii) each outstanding warrant of Forge Nano will be assumed by Pubco and become a corresponding Pubco warrant (the "Pubco Forge Nano Warrants"), subject to the same terms and conditions (including vesting and exercisability) as were applicable to the corresponding Forge Nano warrant; and (iv) each option or other right to acquire securities of Forge Nano and/or its affiliates held by Ascent Funds International Management LLC (together with the Forge Nano warrants, the "Forge Nano Convertible Securities"), will be cancelled and converted into one warrant to purchase shares of Pubco common stock (together with the Pubco Forge Nano Warrants, the "Pubco Convertible Securities"). Under the Merger Agreement, "Closing Payment Shares" means such number of shares of Pubco common stock equal to (a)(i) $1,200,000,000 *divided by* (ii) $10.00 *minus* (b) the Pubco common stock issuable upon exercise of any Pubco Convertible Securities issued in exchange for Forge Nano Convertible Securities, if any.

At the effective time of the First Company Merger, each option to purchase shares of Forge Nano common stock will be converted into an option to purchase shares of Pubco common stock on substantially the same terms and conditions, including with respect to vesting and termination-related provisions (as applicable).

Pursuant to the terms of the Merger Agreement, and subject to the terms and conditions set forth therein, the Forge Nano stockholders who receive Closing Payment Shares and the holders of Pubco Convertible Securities issued in exchange for Forge Nano Convertible Securities, if any, will be entitled to receive, a proportional amount of up to an aggregate of 90,000,000 additional shares of Pubco common stock, issuable upon achievement of certain milestones during the five (5) year period following the closing date. The earn-out shares will be issued at or prior to the closing to the escrow agent and will be disbursed therefrom upon achievement of the applicable milestones. The earn-out shares attributable to holders of Pubco Convertible Securities issued in exchange for Forge Nano Convertible Securities, if any, pursuant to the Merger Agreement will only be disbursed by the escrow agent if an applicable milestone is achieved upon the exercise, conversion or settlement thereof in accordance with their terms.

Immediately following the effective time of the First Company Merger, the Initial Surviving Corporation will merge with and into Merger Sub II (the "Second Company Merger" and together with the First Company Merger and the Reincorporation, the "Business Combination"), with Merger Sub II surviving and Pubco acquiring one membership interest in surviving company and such membership interest will constitute the only outstanding equity of the surviving company.

The Merger Agreement contains customary representations, warranties and covenants of the parties thereto. The consummation of the proposed transactions is subject to certain conditions as further described in the Merger Agreement.

Concurrently with their entry into the Merger Agreement, ATII and Forge Nano entered into a support agreement (the "Purchaser Sponsor Agreement") with the Sponsor, pursuant to which the Sponsor agreed, among other things, (i) to vote in favor of the approval and adoption of the Merger Agreement and the Business Combination, (ii) to not redeem, sell or tender, during the term of the Purchaser Support Agreement, any ordinary shares of the Company owned by the Sponsor in connection with the Business Combination and (iii) to not transfer any ordinary shares of the Company held by the Sponsor in accordance with the lock-up provisions set forth in ATII's final prospectus filed with the SEC on February 11, 2025.

Pursuant to the Purchaser Support Agreement, and subject to the terms and conditions set forth therein, the Sponsor also agreed to contribute up to 3,300,000 ordinary shares, together with all shares of Pubco common stock issued upon conversion thereof, including any securities paid as dividends or distributions with respect to or into which such shares are exchanged or converted (the "Contribution Shares") to secure one or more financing transactions in connection with the Business Combination. Any Contribution Shares not used to secure financing transactions will be retained by the Sponsor.

In connection with their entry into the Merger Agreement, ATII and Forge Nano entered into a lock-up agreement (the "Lock-Up Agreement") with certain stockholders of Forge Nano. Pursuant to the Lock-Up Agreement, such Forge Nano stockholders agreed that they will not, during the Lock-Up Period (as defined below), directly or indirectly sell, exchange, assign, transfer (including by merger, conversion or operation of law), gift or otherwise dispose, any of the shares received as merger consideration, or make a public announcement of any intention to effect such a transfer. As used herein, "Lock-Up Period" means the period commencing on the closing date of the Business Combination and ending on the earlier of: (i) six months after the closing; and (ii) the date on which the last reported sale price of the Pubco common stock equals or exceeds $12.00 per share for any 20 trading days within any 30 trading day period after the closing.

At the closing, ATII, the Sponsor and certain stockholders of Forge Nano (collectively, the "Subject Parties") will enter into a registration rights agreement (the "Registration Rights Agreement"), pursuant to which, among other things, Pubco will be obligated to file a registration statement on Form S-1 with the SEC as soon as practicable but no later than 30 calendar days following the closing of the Business Combination to register the resale of certain securities of Pubco held by the Subject Parties, subject to customary liquidated damages in the event Pubco is unable to meet the filing deadline. The Registration Rights Agreement will also provide the Subject Parties with "piggy-back" registration rights, subject to certain requirements and customary conditions. All expenses of registration under the Registration Rights Agreement, including the legal fees of one firm of counsel chosen by stockholders participating in a registration, will be paid by Pubco.

In connection with the execution of the Merger Agreement, ATII, Pubco and Forge Nano entered into a subscription agreement (the "Subscription Agreement") with an accredited investor, pursuant to which Pubco will, substantially concurrently with, and contingent upon, the consummation of the Business Combination, sell an aggregate of 10,000,000 shares of Pubco common stock and warrants to purchase an aggregate of 15,000,000 shares of Pubco common stock to such investor, each with an exercise price of $10.00 (subject to adjustments) for an aggregate purchase price of $100,000,000.

On May 5, 2026, Registration Statement on Form S-4 was filed with the SEC with respect to the Business Combination.

**Results of Operations**

We have neither engaged in any operations nor generated any revenues to date. Our only activities from inception through March 31, 2026 were organizational activities, those necessary to prepare for the IPO, and, following the IPO, identifying a target company and negotiating for an initial business combination. We do not expect to generate any operating revenues until after the completion of our initial business combination. We generate non-operating income in the form of interest income on demand deposits held in the Trust Account. We incur expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance), as well as for due diligence expenses.

For the three months ended March 31, 2026, we had a net income of $1,704,803, which consists of interest earned on cash held in Trust Account of $2,141,962 and interest earned on cash in bank account of $11,514, offset by general and administrative expenses of $488,673.

For the three months ended March 31, 2025, we had a net income of $1,159,223, which consists of interest income on cash held in Trust Account of $1,305,884 and interest earned on cash in bank account of $10,790, offset by general and administrative expenses of $157,451.

**Liquidity and Capital Resources**

Until the consummation of the Initial Public Offering, our only source of liquidity was an initial purchase of ordinary shares by the Sponsor and loans from the Sponsor. All outstanding loans were repaid simultaneously with the closing of the Initial Public Offering.

On February 12, 2025, we consummated the Initial Public Offering of 23,000,000 Units, 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 and one-half of one Public Warrant, 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, we consummated the sale of an aggregate of 840,000 Private Placement Units at a price of $10.00 per Private Placement Unit in a private placement to the Sponsor and BTIG, generating gross proceeds of $8,400,000.

Following closing of the Initial Public Offering and the sale of the Private Placement Units, a total of $231,150,000 was placed in the Trust Account. We incurred $13,175,520 in transaction costs, consisting of $4,600,000 of cash underwriting fee, $8,050,000 of deferred underwriting fee and $525,520 of other offering costs.

For three months ended March 31, 2026, cash used in operating activities was $208,688. Net income of $1,704,803 was reduced by the interest earned on cash held in Trust Account of $2,141,962 and increased by the general and administrative expenses paid by related parties of $4,283. Changes in operating assets and liabilities provided $224,188 of cash for operating activities.

For the three months ended March 31, 2025, cash used in operating activities was $254,007. Net income of $1,159,223 was reduced by the interest earned on cash held in Trust Account of $1,305,884, and increased by the general and administrative expenses paid through promissory note – related party of $51,600 and general and administrative expenses paid by related parties of $2,926. Changes in operating assets and liabilities used $161,872 of cash for operating activities.

As of March 31, 2026, we had cash held in Trust Account of $242,002,931, which was 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). We may withdraw interest from the Trust Account to pay taxes, if any. 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 initial business combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our initial 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 March 31, 2026, we had cash outside the Trust Account of $1,077,839. We intend 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 an initial business combination.

In order to fund working capital deficiencies or finance transaction costs in connection with an initial 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 an initial business combination, we would repay such loaned amounts. In the event that an initial 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 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," we do not believe we will need to raise additional funds in order to meet the expenditures required for operating our business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating an initial business combination are less than the actual amount necessary to do so, we may have insufficient funds available to operate our 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.

**Off-Balance Sheet Arrangements**

We have no obligations, assets or liabilities, which would be considered off-balance sheet arrangements as of March 31, 2026. 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 the Sponsor a monthly fee of $10,000 for office space, administrative and support services. We began incurring these fees on February 10, 2025 and will continue to incur these fees monthly until the earlier of the completion of the initial business combination and our liquidation.

The underwriters are entitled to a deferred fee of $0.35 per Unit, or $8,050,000 in the aggregate. The deferred fee will become payable to the underwriters from the amounts held in the Trust Account solely in the event that we complete an initial business combination, subject to the terms of the underwriting agreement.

**Critical Accounting Policies**

The preparation of unaudited condensed consolidated 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 unaudited condensed consolidated financial statements, and income and expenses during the periods reported. Making estimates requires management to exercise significant judgement. 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 unaudited condensed consolidated 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 materially differ from those estimates. As of March 31, 2026, we did not have any critical accounting estimates to be disclosed.

*Recent Accounting Standards*

In August 2020, the FASB issued Accounting Standards Update ("ASU") 2020-06, "Debt — Debt with Conversion and Other Options (Subtopic 470-20) and Derivatives and Hedging — Contracts in Entity's Own Equity (Subtopic 815-40)" ("ASU 2020-06"), to simplify certain financial instruments. ASU 2020-06 eliminates the current models that require separation of beneficial conversion and cash conversion features from convertible instruments and simplifies the derivative scope exception guidance pertaining to equity classification of contracts in an entity's own equity. The new standard also introduces additional disclosures for convertible debt and freestanding instruments that are indexed to and settled in an entity's own equity. ASU 2020-06 amends the diluted earnings per share guidance, including the requirement to use the if-converted method for all convertible instruments. ASU 2020-06 is effective for fiscal years beginning after December 15, 2023 and should be applied on a full or modified retrospective basis. Early adoption is permitted, but no earlier than fiscal years beginning after December 15, 2020, including interim periods within those fiscal years. The Company adopted ASU 2020-06 as of inception, June 7, 2024. There was no effect to the Company's presented financial statement.

In November 2023, the FASB issued ASU 2023-07, Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures. The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating officer decision maker ("CODM"), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. The ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities will be required to provide all annual disclosures currently required by Topic 280 in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in this ASU and existing segment disclosures in Topic 280. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 on December 31, 2025.

Management does not believe that any other recently issued, but not yet effective, accounting standards, if currently adopted, would have a material effect on the Company's financial statement.

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

As of March 31, 2026, we were not subject to any market or interest rate risk. Following the consummation of our Initial Public Offering, the net proceeds of our Initial Public Offering, including amounts in the Trust Account, have been invested in U.S. government treasury obligations with a maturity of 185 days or less or in certain money market funds that invest solely in U.S. treasuries. Due to the short-term nature of these investments, we believe there will be no associated material exposure to interest rate risk.

**Item 4. Controls and Procedures.**

**Evaluation of Disclosure Controls and Procedures**

Disclosure controls and procedures are designed to ensure that information required to be disclosed by us in our Exchange Act reports is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms, and that such information is accumulated and communicated to our management, including our principal executive officer and principal financial officer or persons performing similar functions, as appropriate to allow timely decisions regarding required disclosure.

Under the supervision and with the participation of our management, including our principal executive officer and principal financial and accounting officer, we conducted an evaluation of the effectiveness of our disclosure controls and procedures as of the end of the fiscal quarter ended March 31, 2026, as such term is defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on this evaluation, our principal executive officer and principal financial and accounting officer have concluded that during the period covered by this report, our disclosure controls and procedures were effective at a reasonable assurance level and, accordingly, provided reasonable assurance that the information required to be disclosed by us in reports filed under the Exchange Act is recorded, processed, summarized and reported within the time periods specified in the SEC's rules and forms.

**Changes in Internal Control over Financial Reporting**

There was no change in our internal control over financial reporting that occurred during the fiscal quarter of 2026 covered by this Quarterly Report on Form 10-Q that has materially affected, or is reasonably likely to materially affect, our internal control over financial reporting.

**PART II** – **OTHER INFORMATION**

**Item 1. Legal Proceedings.**

None.

**Item 1A. Risk Factors.**

We are a smaller reporting company as defined by Rule 12b-2 of the Exchange Act and are not required to provide the information otherwise required under this item.

**Item 2. Unregistered Sales of Equity Securities and Use of Proceeds.**

On June 7, 2024, the Sponsor subscribed for 5,750,000 founder shares for a total subscription price of $25,000 and fully paid for those shares (up to 750,000 shares of which were subject to forfeiture depending on the extent to which the underwriters' over-allotment option is exercised). As a result of the underwriters' election to fully exercise their over-allotment option on February 12, 2025, the 750,000 founder shares were no longer subject to forfeiture. The foregoing issuance of securities was made pursuant to the exemption from registration contained in Section 4(a)(2) of the Securities Act.

[**Table of Contents**](#toc)

On February 12, 2025, we consummated the Initial Public Offering of 23,000,000 Units, 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 and one-half of one Public Warrant, 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, we consummated the sale of an aggregate of 840,000 Private Placement Units at a price of $10.00 per Private Placement Unit in a private placement to the Sponsor and BTIG, generating gross proceeds of $8,400,000.

Of the gross proceeds received from the Initial Public Offering and the private placement of the Private Placement Units, an aggregate of $231,150,000 was placed in the Trust Account. The proceeds held in the Trust Account may be invested by the trustee 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 specific investments in our Trust Account may change from time to time.

We incurred a total of $13,175,520 in transaction costs, consisting of $4,600,000 of cash underwriting fee, $8,050,000 of deferred underwriting fee and $525,520 of other offering costs.

For a description of the use of the proceeds generated in our Initial Public Offering, see Part I, Item 2 of this report.

## Exhibit 31.2

**EXHIBIT 31.2**

**CERTIFICATION OF PRINCIPAL FINANCIAL OFFICER**

**PURSUANT TO RULE 13A-14(A) UNDER THE SECURITIES EXCHANGE ACT OF 1934, AS ADOPTED PURSUANT TO SECTION 302 OF THE SARBANES-OXLEY ACT OF 2002**

I, Daniel L. Sheehan, certify that:

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;1. I have reviewed this quarterly report on Form 10-Q of Archimedes Tech SPAC Partners II Co.;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;2. Based on my knowledge, this report does not contain any untrue statement of a material fact or omit to state a material fact necessary to make the statements made, in light of the circumstances under which such statements were made, not misleading with respect to the period covered by this report;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;3. Based on my knowledge, the financial statements, and other financial information included in this report, fairly present in all material respects the financial condition, results of operations and cash flows of the registrant as of, and for, the periods presented in this report;

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;4. The registrant's other certifying officer(s) and I are responsible for establishing and maintaining disclosure controls and procedures (as defined in Exchange Act Rules 13a-15(e) and 15d-15(e)) for the registrant and internal control over financial reporting (as defined in Exchange Act Rules 13a-15(f) and 15d-15(f)) for the registrant and have:
