#### NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

#### MARCH 31, 202 6
(UNAUDITED)

#### Note 1 — Description of Organization and Business Operations

#### Organization and General
Churchill Capital Corp IX (the "Company") was incorporated as a Cayman Islands exempted company on December 18, 2023. The Company was incorporated for the purpose of effecting a merger, amalgamation, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the "Business Combination") that the Company, as of its incorporation, had not yet identified. The Company is an "emerging growth company," as defined in Section 2(a) of the Securities Act of 1933, as amended (the "Securities Act"), as modified by the Jumpstart Our Business Startups Act of 2012 (the "JOBS Act").

The Company has two direct wholly-owned subsidiaries, AL Merger Sub I, Inc. ("Merger Sub I"), a Delaware corporation, and AL Merger Sub II, LLC, a Delaware limited liability company ("Merger Sub II", and collectively with Merger Sub I, the "Merger Subs"). The Merger Subs were formed on June 2, 2025, for the sole purpose of effecting the then prospective business combination between PlusAI (as defined below) and the Company that was contemplated under the PlusAI Merger Agreement (as defined below) (the "PlusAI Business Combination") which was terminated in April 2026 (as described below).

As of March 31, 2026, the Company had not yet commenced operations. All activity for the period from December 18, 2023 (inception) through March 31, 2026 relates to (i) the Company's formation and the Initial Public Offering (as defined below), and (ii) subsequent to the Initial Public Offering, identifying a target company for an initial Business Combination and activities in connection with attempting to complete a Business Combination. The Company will not generate any operating revenues until after the completion of its initial Business Combination at the earliest. The Company generates non-operating income in the form of interest income from the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

#### Sponsor and Initial Public Offering
The Company's sponsor is Churchill Sponsor IX LLC (the "Sponsor"), an affiliate of M. Klein and Company, LLC. The registration statement for the Initial Public Offering was declared effective on May 1, 2024 (the "IPO Registration Statement"). On May 6, 2024, the Company consummated the initial public offering of 28,750,000 units (the "Units" and, with respect to the shares of Class A ordinary shares included in the Units offered, the "Public Shares"), which includes the full exercise by the underwriters of their over-allotment option in the amount of 3,750,000 Units, at $10.00 per Unit, generating gross proceeds of $287,500,000, which is discussed in Note 3 (the "Initial Public Offering"). Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 725,000 private placement units (the "Private Placement Units") to the Sponsor at a price of $10.00 per Unit, or $7,250,000 in the aggregate, which is described in Note 4 (the "Private Placement").

Transaction costs amounted to $14,560,986, consisting of $5,750,000 of upfront discount to the underwriters, $10,062,500 of deferred underwriting fees, and $557,236 of other offering costs, offset by a reimbursement from the underwriters of $1,808,750.

#### The Trust Account
Following the closing of the Initial Public Offering, on May 6, 2024, an amount of $287,500,000 ($10.00 per Unit) from the net proceeds of the sale of the Units in the Initial Public Offering and the sale of the Private Placement Units in the Private Placement was placed in the trust account (the "Trust Account"). The proceeds held in the Trust Account are invested only in U.S. government treasury bills with a maturity of one hundred eighty-five (185) days or less or in money market funds that meet certain conditions under Rule 2a-7 under the Investment Company Act of 1940 (the "Investment Company Act") and that invest only in direct U.S. government obligations and may at any time be held as cash or cash items, including in demand deposit accounts at a bank. Funds will remain in the Trust Account until the earlier of (i) the consummation of the initial Business Combination or (ii) the distribution of the Trust Account proceeds as described below. The remaining proceeds outside the Trust Account may be used to pay for business, legal and accounting due diligence on prospective acquisitions and continuing general and administrative expenses.

The Company's amended and restated memorandum and articles of association provide that, other than the permitted withdrawals (as defined below), if any, none of the funds held in the Trust Account will be released until the earlier of (i) the completion of the initial Business Combination; (ii) the redemption of any Public Shares that have been properly submitted in connection with a shareholder vote to approve an amendment to the Company's amended and restated memorandum and articles of association (A) in a manner that would affect the substance or timing of its obligation to redeem 100% of the Public Shares if it does not complete an initial Business Combination within 24 months from the closing of the Initial Public Offering (or 27 months from the closing of the Initial Public Offering if the Company has executed a letter of intent, agreement in principle or definitive agreement for an initial Business Combination within 24 months from the closing of the Initial Public Offering) (such 24 or 27 month period, as may be amended, the "Combination Period") or (B) with respect to any other provision relating to the rights of holders of the Public Shares or pre-initial Business Combination activity; and (iii) the redemption of 100% of the Public Shares if the Company is unable to complete an initial Business Combination within the Combination Period. The proceeds deposited in the Trust Account could become subject to the claims of the Company's creditors, if any, which could have priority over the claims of the Company's public shareholders. As a result of the Company having entered into the PlusAI Merger Agreement (as defined below), the Company has until August 6, 2026 to complete its initial Business Combination.

#### MARCH 31, 2026
(UNAUDITED)

#### Initial Business Combination
The Company's management has broad discretion with respect to the specific application of the net proceeds of the Initial Public Offering, although substantially all of the net proceeds of the Initial Public Offering are intended to be generally applied toward consummating an initial Business Combination. The initial Business Combination must occur with one or more target businesses that together have an aggregate fair market value of at least 80% of the assets held in the Trust Account (excluding the deferred underwriting commissions and taxes payable on income earned on the Trust Account) at the time of the agreement to enter into the initial Business Combination. Furthermore, there is no assurance that the Company will be able to successfully effect an initial Business Combination.

The Company, after signing a definitive agreement for an initial Business Combination, will either (i) seek shareholder approval of the initial Business Combination at a meeting called for such purpose in connection with which shareholders may seek to redeem their shares, regardless of whether they vote for or against the initial Business Combination, for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest earned on the funds held in the Trust Account (net of amounts withdrawn to fund the working capital requirements, subject to an annual limit of $1,000,000, and to pay taxes ("permitted withdrawals")), or (ii) provide shareholders with the opportunity to sell their Public Shares to the Company by means of a tender offer (and thereby avoid the need for a shareholder vote) for an amount in cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account as of two business days prior to the consummation of the initial Business Combination, including interest less permitted withdrawals. The decision as to whether the Company will seek shareholder approval of the initial Business Combination or will allow shareholders to sell their Public Shares in a tender offer will be made by the Company, solely in its discretion, and will be based on a variety of factors such as the timing of the transaction and whether the terms of the transaction would otherwise require the Company to seek shareholder approval, unless a vote is required by law or under Nasdaq rules.

Pursuant to the Company's amended and restated memorandum and articles of association if the Company is unable to complete the initial Business Combination within the Combination Period, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than ten business days thereafter, subject to lawfully available funds therefor, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account including interest earned (which interest shall be net of permitted withdrawals and up to $100,000 of interest to pay dissolution expenses and net of taxes payable), divided by the number of then outstanding Public Shares, which redemption will completely extinguish the holders' rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the Company's remaining shareholders and the Company's board of directors (the "Board"), dissolve and liquidate, subject in each case to the Company's obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Sponsor, officers and directors are not entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Shares (as defined below) held by them if the Company fails to complete the initial Business Combination within the Combination Period. However, if the Sponsor and management team acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such shares if the Company fails to complete the initial Business Combination within the prescribed time period.

In the event of a liquidation, dissolution or winding up of the Company after an initial Business Combination, the Company's shareholders are entitled to share ratably in all assets remaining available for distribution after payment of liabilities and after provision is made for each class of shares, if any, having preference over the ordinary shares. The Company's shareholders have no preemptive or other subscription rights. There are no sinking fund provisions applicable to the ordinary shares, except that the Company will provide its shareholders with the opportunity to redeem their Public Shares for cash equal to their pro rata share of the aggregate amount then on deposit in the Trust Account, upon the completion of the initial Business Combination, subject to the limitations described herein.

#### Termination of PlusAI Business Combination Agreement
On June 5, 2025, the Company entered into an Agreement and Plan of Merger and Reorganization (as amended by Amendment No. 1 dated September 8, 2025 and Amendment No. 2 dated September 18, 2025 and as may be further amended, modified, supplemented or waived from time to time, the "PlusAI Merger Agreement") by and among the Company, Merger Sub I, Merger Sub II and Plus Automation, Inc., a Delaware corporation ("PlusAI").

On April 20, 2026, the Company and PlusAI entered into a Termination Agreement (the "Termination Agreement") pursuant to which the PlusAI Merger Agreement was terminated by the mutual consent of the Company and PlusAI, effective as of April 20, 2026, due to market conditions. As a result of the mutual termination of the PlusAI Merger Agreement, that agreement became of no further force and effect, except as set forth in the Termination Agreement. The mutual termination of the PlusAI Merger Agreement also terminated and made void the transaction agreements that were entered into in connection with the PlusAI Merger Agreement.

(UNAUDITED)

#### 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.

#### Liquidity, Capital Resources and Going Concern
As of March 31, 2026, the Company had $167,798 of cash and a working capital deficit of $664,401. In order to finance working capital deficit or to finance transaction costs in connection with an intended 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 ("Working Capital Loans"). If the Company completes its initial Business Combination, the Company would repay the Working Capital Loans. In the event that the initial Business Combination does not close, the Company may use a portion of the working capital held outside the Trust Account to repay the Working Capital Loans, but no proceeds from the Trust Account would be used to repay the Working Capital Loans. If the Sponsor makes any Working Capital Loans, up to $1,500,000 of the Working Capital Loans may be convertible into units of the post Business Combination entity at a price of $10.00 per unit at the option of the lender. The units and the underlying securities would be identical to the Private Placement Units (See Note 5).

On December 2, 2025, the Company issued an unsecured promissory note (the "WCL Promissory Note") in the aggregate principal amount of up to $1,500,000 to the Sponsor, for any Working Capital Loans the Sponsor may make to the Company. The WCL Promissory Note does not bear interest and matures upon the earlier of the closing of an initial Business Combination by the Company and the Company's liquidation.

Amounts outstanding under the WCL Promissory Note are convertible, at the option of the Sponsor, into units of the Company (the "WCL Conversion Units"), at a conversion price of $10.00 per WCL Conversion Unit, with each unit consisting of one share of the Company's Class A Ordinary Share and one-quarter of one warrant, with each whole warrant exercisable for one Class A Ordinary Share at $11.50 per share, subject to adjustment as provided in the IPO Registration Statement. The WCL Conversion Units (and underlying securities) will be identical to the Private Placement Units (and underlying securities) issued in the Private Placement. The WCL Conversion Units are entitled to registration rights. As of March 31, 2026, and December 31, 2025, the Company borrowed $500,000 and $0, respectively, under the WCL Promissory Note. As of March 31, 2026, the Company has $1,000,000 available under the WCL Promissory Note.

Additionally, to fund working capital, the Company has permitted withdrawals available up to an annual limit of $1,000,000. These permitted withdrawals are limited to only the interest available that has been earned in excess of the initial deposit at the Initial Public Offering. During the year ended December 31, 2024, the Company had withdrawn $1,000,000 in interest for working capital purposes and had no further amounts available for permitted withdrawals until May 6, 2025, which was the one-year anniversary of the Initial Public Offering. For the year ended December 31, 2025, the Company withdrew another $1,000,000 in interest from the Trust Account for working capital purposes and has no further amounts available for permitted withdrawals until May 6, 2026, which is the two-year anniversary of the Initial Public Offering. As of March 31, 2026, no further amounts are available for withdrawal until May 6, 2026.

In connection with the Company's assessment of going concern considerations in accordance with Financial Accounting Standards Board ("FASB") Accounting Standards Codification ("ASC") Topic 205-40, "Going Concern," as of this filing, the Company does not believe it will have sufficient funds for the working capital needs of the Company until a minimum of one year from the date of the accompanying consolidated financial statements. Moreover, the Company will need to obtain additional financing either to complete a Business Combination, or because the Company becomes obligated to redeem a significant number of Public Shares upon completion of the Business Combination, in which case the Company may issue additional securities or incur debt in connection with such Business Combination. Accordingly, the Company may not be able to obtain additional financing. If the Company is unable to raise additional capital, it may be required to take additional measures to conserve liquidity, which could include, but not necessarily be limited to, curtailing operations, suspending the pursuit of a potential transaction, and reducing overhead expenses. The Company cannot provide any assurance that new financing will be available to it on commercially acceptable terms, if at all.

#### MARCH 31, 2026
(UNAUDITED)

The Company's liquidity condition and mandatory liquidation in the event the Company does not complete a Business Combination within the Combination Period raise substantial doubt about the Company's ability to continue as a going concern for a period of time within one year from the date of the accompanying unaudited condensed consolidated financial statements. Management plans to address this uncertainty by completing a Business Combination. If a Business Combination is not consummated by the end of the Combination Period, currently August 6, 2026, there will be a mandatory liquidation and subsequent dissolution of the Company, which raises substantial doubt about the Company's ability to continue as a going concern. No adjustments have been made to the carrying amounts of assets or liabilities should the Company be required to liquidate after the Combination Period. The Company intends to complete the initial Business Combination before the end of the Combination Period. However, there can be no assurance that the Company will be able to consummate any Business Combination by the end of Combination Period.

#### 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 U.S. Securities and Exchange Commission (the "SEC"). Certain information or footnote disclosures normally included in 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 as filed with the SEC on February 5, 2026. The interim results for the three months ended March 31, 2026 and 2025 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
On June 2, 2025, the Merger Subs were formed.

The accompanying condensed consolidated financial statements include the accounts of the Company and its wholly owned subsidiaries. All significant intercompany balances and transactions have been eliminated in consolidation.

#### Emerging Growth Company Status
As an emerging growth company, the Company may take advantage of certain exemptions from various reporting requirements that are applicable to other public companies that are not emerging growth companies including, but not limited to, not being required to comply with the auditor attestation requirements of Section 404 of the Sarbanes-Oxley Act of 2002, as amended, reduced disclosure obligations regarding executive compensation in its periodic reports and proxy statements, and exemptions from the requirements of holding a non-binding advisory vote on executive compensation and shareholder approval of any golden parachute payments not previously approved.

Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Securities Exchange Act of 1934, as amended) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that a company can elect to opt out of the extended transition period and comply with the requirements that apply to non-emerging growth companies but any such election to opt out is irrevocable. The Company has elected not to opt out of such extended transition period which means that when a standard is issued or revised and it has different application dates for public or private companies, the Company, as an emerging growth company, can adopt the new or revised standard at the time private companies adopt the new or revised standard. This may make comparison of the Company's condensed consolidated financial statements with another public company which is neither an emerging growth company nor an emerging growth company that has opted out of using the extended transition period difficult or impossible because of the potential differences in accounting standards used.

#### 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 $167,798 and $2,469 in cash and no cash equivalents as of March 31, 2026 and December 31, 2025, respectively.

#### CHURCHILL CAPITAL CORP IX

#### NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

#### MARCH 31, 2026
(UNAUDITED)

#### Marketable Securities and Cash Held in Trust Account
The Company classifies its U.S. Treasury and equivalent securities as held-to-maturity in accordance with FASB ASC Topic 320, "Investments—Debt and Equity Securities." Held-to-maturity securities are those securities which the Company has the ability and intent to hold until maturity. Held-to-maturity treasury securities are recorded at amortized cost on the accompanying condensed consolidated balance sheets and adjusted for the amortization or accretion of premiums or discounts. At March 31, 2026, $310,264,509 was invested in money market funds invested in U.S. Treasury Securities and $0 was held in cash, as reflected on the accompanying condensed consolidated balance sheet (see Note 8). At December 31, 2025, $307,660,577 was invested in U.S. Treasury Securities and $235 was held in cash, at an amortized cost of $307,617,399 as reflected on the accompanying condensed consolidated balance sheet (see Note 8).

#### Offering Costs
The Company complies with the requirements of the FASB ASC Topic 340-10-S99 and SEC Staff Accounting Bulletin Topic 5A, "Expenses of Offering." Deferred offering costs consist principally of professional and registration fees that are related to the 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 Class A 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 Class A ordinary shares. Offering costs allocated to the Public Shares were charged to temporary equity, and offering costs allocated to the Private Placement Units and Public Warrants (as defined in Note 3) were charged to shareholders' deficit (see Note 4).

Transaction costs amounted to $14,560,986, consisting of $5,750,000 of upfront discount to the underwriters, $10,062,500 of deferred underwriting fees, and $557,236 of other offering costs, offset by a reimbursement from the underwriters of $1,808,750.

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

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

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

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

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

#### Use of Estimates
The preparation of the accompanying condensed consolidated financial statements in conformity with GAAP requires the Company's management to make estimates and assumptions that affect the reported amounts of assets and liabilities and disclosure of contingent assets and liabilities at the date of the accompanying condensed consolidated financial statements and the reported amounts of expenses during the reporting period.

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 accompanying 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.

#### Net Income Per Ordinary Share
The Company complies with accounting and disclosure requirements of FASB ASC Topic 260, "Earnings Per Share." The Company has two classes of ordinary shares, which are referred to as Class A ordinary shares and Class B ordinary shares. Income and losses are shared pro rata between the two classes of ordinary shares. Net income per ordinary share is calculated by dividing the net income by the weighted average ordinary shares outstanding for the respective period. Diluted net income per share attributable to ordinary shareholders adjusts the basic net income per share attributable to ordinary shareholders and the weighted-average ordinary shares outstanding for the potentially dilutive impact of outstanding warrants.

With respect to the accretion of Class A ordinary shares subject to possible redemption and consistent with FASB ASC Topic 480-10-S99-3A, "Distinguishing Liabilities from Equity" ("ASC 480-10-S99"), the Company treated accretion in the same manner as a dividend paid to the shareholders in the calculation of the net income per ordinary share.

The following table reflects the calculation of basic and diluted net income per ordinary share:

---

| | | | | |
|:---|:---|:---|:---|:---|
|  | For the Three Months Ended March 31, | For the Three Months Ended March 31, | For the Three Months Ended March 31, | For the Three Months Ended March 31, |

|  Basic and diluted income per share | $0.04 | $0.04 | $0.07 | $0.07 |

---

#### Income Taxes
The Company accounts for income taxes under FASB ASC Topic 740, "Income Taxes" ("ASC 740"), which requires an asset and liability approach to financial accounting and reporting for income taxes. Deferred income tax assets and liabilities are computed for differences between the 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 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.

#### **Table of Contents**

#### CHURCHILL CAPITAL CORP IX

#### NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

#### MARCH 31, 2026
(UNAUDITED)

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.

#### Class A 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 Public Shares sold as part of the Units in the Initial Public Offering were issued with other freestanding instruments (i.e., Public Warrants), and as such, the initial carrying value of Public Shares classified as temporary equity are the allocated proceeds determined in accordance with ASC 470-20. 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 Public Shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, at March 31, 2026 and December 31, 2025, Class A 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.

At March 31, 2026 and December 31, 2025, the Class A ordinary shares subject to redemption reflected in the condensed consolidated balance sheets are reconciled in the following table:

#### Warrant Instruments
The Company accounts for the Public Warrants and Private Warrants (as defined in Note 4) issued in connection with the Initial Public Offering and the Private Placement in accordance with the guidance contained in FASB ASC Topic 815, "Derivatives and Hedging." Accordingly, the Company evaluated and classified the warrant instruments under equity treatment at their assigned values.

#### Recent Accounting Standards
In November 2024, the FASB issued ASU 2024-03, Income Statement — Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income — Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date ("ASU 2025-01"). ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact these standards will have on it unaudited condensed financial statements.

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

(UNAUDITED)

#### Note 3 — Initial Public Offering
Pursuant to the Initial Public Offering, the Company sold 28,750,000 Units, which includes a full exercise by the underwriters of their over-allotment option in the amount of 3,750,000 Units, at a price of $10.00 per Unit. Each Unit consists of one Public Share and one-quarter of one warrant (each, a "Public Warrant" and collectively, the "Public Warrants"). Each Public Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustments (see Note 7).

#### Note 4 — Private Placement
Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 725,000 Private Placement Units at a price of $10.00 per Private Placement Unit in the Private Placement. Each Private Placement Unit consists of one Class A Ordinary Share and one-quarter of one warrant (each, a "Private Warrant" and collectively, the "Private Warrants", and together with the Public Warrants, the "Warrants"). Each Private Warrant entitles the holder to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustments. Each Private Warrant will become exercisable 30 days after the completion of the initial Business Combination and will not expire except upon liquidation. If the initial Business Combination is not completed within the Combination Period, the proceeds from the Private Placement held in the Trust Account will be used to fund the redemption of the Public Shares (subject to the requirements of applicable law).

#### Note 5 — Related Party Transactions

#### Founder Shares
On December 18, 2023, the Company issued an aggregate of 7,187,500 Class B ordinary shares, $0.0001 par value (the "Founder Shares", including the Public Shares issuable upon conversion thereof), in exchange for a $25,000 payment (approximately $0.003 per share) from the Sponsor to cover certain expenses on behalf of the Company. The Founder Shares are identical to the Public Shares included in the Units sold in the Initial Public Offering except that the Founder Shares will automatically convert into Class A ordinary shares at the time of the initial Business Combination (with such conversion taking place immediately prior to, simultaneously with, or immediately following the time of the initial Business Combination, as may be determined by the directors of the Company) or earlier at the option of the holder and are subject to certain transfer restrictions, as described in the IPO Registration Statement. The Sponsor agreed to forfeit up to an aggregate of 937,500 Founder Shares to the extent that the over-allotment option was not exercised in full by the underwriters so that the Founder Shares would represent 20% of the Company's issued and outstanding shares after the Initial Public Offering. As a result of the underwriters' election to fully exercise their over-allotment option on May 6, 2024, such 937,500 Founder Shares are no longer subject to forfeiture.

The Sponsor is not entitled to redemption rights with respect to any Founder Shares and any Public Shares held by the Sponsor in connection with the completion of the initial Business Combination. If the initial Business Combination is not completed within the Combination Period, the Sponsor is not entitled to rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by it.

The Sponsor has agreed not to transfer, assign or sell any of its Founder Shares until the earlier to occur of (A) six months after the completion of the initial Business Combination or (B) subsequent to the initial Business Combination (the date on which the Company consummates a transaction which results in the shareholders having the right to exchange their shares for cash, securities, or other property, subject to certain limited exceptions).

#### Registration Rights
The holders of Founder Shares, Private Placement Units (and their underlying securities) and WCL Conversion Units (and their underlying securities), if any, and any Class A ordinary shares issuable upon conversion of the Founder Shares and any Class A ordinary shares held by the Sponsor at the completion of the Initial Public Offering or acquired prior to or in connection with the initial Business Combination, are entitled to registration rights pursuant to a registration rights agreement signed on the effective date of the IPO Registration Statement. These holders are entitled to make up to three demands and have "piggyback" registration rights. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

#### Administrative Support Agreement
The Company entered into an agreement, commencing on May 2, 2024, that the Company will reimburse an affiliate of the Sponsor in an amount equal to $30,000 per month for office space, utilities and secretarial and administrative support. Upon completion of the initial Business Combination or the Company's liquidation, the Company will cease paying these monthly fees. For the three months ended March 31, 2026, the Company incurred and accrued $90,000 in fees which is included within accrued expenses on the accompanying condensed consolidated balance sheets. For the three months ended March 31, 2025, the Company incurred and paid $90,000 for these services.

#### Director Agreements
On July 30, 2025, the Company entered into director agreements (each, a "Director Agreement" and, together, the "Director Agreements") with each of the three independent directors of the Company, pursuant to which, in connection with each director's continuing service as a director of the Company, the Company agreed to pay each director a cash compensation of $75,000 per annum, beginning on the later of their date of appointment and April 1, 2025. For the three months ended March 31, 2026, the Company incurred $56,250 in fees related to the Director Agreements, and $56,250 is included in accrued expenses within the condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025, respectively. For the three months ended March 31, 2025, the Company did not incur any fees related to the Director Agreements.

#### Working Capital Loans
In addition, in order to finance transaction costs in connection with its initial Business Combination, the Sponsor or an affiliate of the Sponsor, or the Company's officers and directors may, but are not obligated to, provide Working Capital Loans to the Company, as may be required. If the Company completes its initial Business Combination, the Company would repay the Working Capital Loans. In the event that the initial Business Combination does not close, the Company may use a portion of proceeds held outside the Trust Account to repay the Working Capital Loans, but no proceeds held in the Trust Account would be used to repay the Working Capital Loans. If the Sponsor makes any Working Capital Loans, up to $1,500,000 of such loans may be convertible into units of the post-business combination entity at a price of $10.00 per unit at the option of the lender. The units and their underlying securities would be identical to the Private Placement Units. As of March 31, 2026 and December 31, 2025, the Company borrowed $500,000 and $0, respectively under the Working Capital Loans.

On December 2, 2025, the Company issued the WCL Promissory Note in the aggregate principal amount of up to $1,500,000 to the Sponsor, for any Working Capital Loans the Sponsor may make to the Company. The WCL Promissory Note does not bear interest and matures upon the earlier of the closing of an initial Business Combination by the Company and the Company's liquidation.

Amounts outstanding under the WCL Promissory Note are convertible, at the option of the Sponsor, into WCL Conversion Units, at a conversion price of $10.00 per WCL Conversion Unit, with each unit consisting of one share of the Company's Class A ordinary share and one-quarter of one warrant, with each whole warrant exercisable for one Class A Ordinary Share at $11.50 per share, subject to adjustment as provided in the IPO Registration Statement. The WCL Conversion Units (and underlying securities) will be identical to the Private Placement Units (and underlying securities) issued in the Private Placement. The WCL Conversion Units are entitled to registration rights. As of March 31, 2026, and December 31, 2025, the Company borrowed $500,000 and $0, respectively, under the WCL Promissory Note. As of March 31, 2026, the Company has $1,000,000 available under the WCL Promissory Note.

#### Note 6 — Commitments and Contingencies

#### Underwriting Agreement
The underwriters had a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,750,000 Units to cover over-allotments, if any. On May 6, 2024, simultaneously with the closing of the Initial Public Offering, the underwriters elected to fully exercise the over-allotment option to purchase the additional 3,750,000 Units at a price of $9.80 per Unit, after giving effect to the upfront discount of 2%.

The underwriters were entitled to an upfront discount of 2.0% of the per Unit offering price, or $5,750,000 in the aggregate (including Units purchased in connection with the exercise of the over-allotment option). In addition, the underwriters agreed to reimburse the Company for certain expenses in connection with the Initial Public Offering. On May 6, 2024, the Company received a reimbursement from the underwriters of $1,808,750 at the Initial Public Offering. An additional fee of 3.5% of the gross offering proceeds, or $10,062,500 in the aggregate, is payable to the underwriters from the amount held in the Trust Account, only upon the Company's completion of its initial Business Combination (the "Deferred Discount").

The Deferred Discount will become payable to the underwriters from the amount held in the Trust Account solely in the event the Company completes its initial Business Combination.

On June 4, 2025, the Company entered into an advisory agreement (the "Advisory Agreement") with Citigroup Global Markets Inc., the representative of the underwriters in the Initial Public Offering (the "Advisor") to provide capital market advisory services in connection with the PlusAI Business Combination. Following the termination of the PlusAI Merger Agreement, the Company terminated the Advisory Agreement. The Advisor is not entitled to any cash fee as a result of the termination.

#### Legal and Due Diligence Fees
On April 22, 2025, the Company entered into an agreement for legal services. All fees related to the agreement are contingent upon the completion of a Business Combination. Upon the completion of the Business Combination, in addition to payment of incurred fees, the Company will pay a premium ranging from 50% to 100% of the fees incurred, with the percentage paid to be determined at the Company's discretion. As of March 31, 2026 and December 31, 2025, the Company had incurred approximately $4,570,000 and $3,420,000 of fees, respectively, in connection with such agreement. These fees are not reflected in the condensed consolidated financial statements included elsewhere in this Report and will be recorded when the Business Combination is considered probable.

On May 2, 2025, the Company entered into an agreement for due diligence services. The total fee related to the due diligence services was $1,050,000, of which $900,000 was paid and included in the accompanying condensed consolidated statements of operations. The remaining $150,000 is subject to customer satisfaction and due upon the consummation of a Business Combination.

#### Note 7 — Shareholders' Deficit

#### Preference Shares
The Company is authorized to issue 5,000,000 preference shares with a par value of $0.0001 per share, with such designations, voting and other rights and preferences as may be determined from time to time by the Board. As of March 31, 2026 and December 31, 2025, there were no preference shares issued or outstanding.

#### Class A Ordinary Shares
The Company is authorized to issue up to 500,000,000 Class A ordinary shares with a par value of $0.0001 per share. If the Company enters into an initial Business Combination, it may (depending on the terms of such an initial Business Combination) be required to increase the number of Class A ordinary shares that the Company is authorized to issue at the same time as the Company's shareholders vote on the initial Business Combination, to the extent the Company seeks shareholder approval in connection with the initial Business Combination. Holders of the Company's ordinary shares are entitled to one vote for each ordinary share (except as otherwise expressed in the Company's amended and restated memorandum and articles of association). As of March 31, 2026 and December 31, 2025, there are 725,000 Class A ordinary shares issued and outstanding, excluding 28,750,000 Class A ordinary shares subject to possible redemption.

#### Class B Ordinary Shares

As of March 31, 2026 and December 31, 2025, there were 7,187,500 Founder Shares issued and outstanding.

#### Warrants
As of March 31, 2026 and December 31, 2025, there were 7,368,750 Warrants (7,187,500 Public Warrants and 181,250 Private Warrants) outstanding. Each whole Warrant entitles the holder thereof to purchase one Class A ordinary share at a price of $11.50 per share, subject to adjustment as described herein, at any time commencing 30 days after the completion of the initial Business Combination, provided that the Company has an effective registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the Warrants and a current prospectus relating to them is available (or the Company permits holders to exercise their Warrants on a "cashless basis" under the circumstances specified in the warrant agreements entered into in connection with the Initial Public Offering) and such shares are registered, qualified or exempt from registration under the securities, or blue sky, laws of the state of residence of the holder. Pursuant to the (i) Public Warrant Agreement, dated May 1, 2024, which the Company entered into with Continental Stock Transfer & Trust Company ("Continental"), as Public Warrant agent and (ii) Private Warrant Agreement, dated May 1, 2024, which the Company entered into with Continental, as Private Placement Warrant agent (together, the "Warrant Agreements"), a warrant holder may exercise its Warrants only for a whole number of Class A ordinary shares. This means that only a whole Warrant may be exercised at any given time by a warrant holder. No fractional Warrants will be issued upon separation of the units and only whole Warrants will trade. The Public Warrants will expire five years after the completion of the initial Business Combination, at 5:00 p.m., New York City time, or earlier upon redemption or liquidation.

The Company did not register the Public Shares issuable upon exercise of the Warrants at the time of the Initial Public Offering. However, the Company has agreed that as soon as practicable, but in no event later than fifteen (15) business days after the closing of the initial Business Combination, the Company will use its commercially best efforts to file with the SEC a post-effective amendment to the IPO Registration Statement or a new registration statement registering, under the Securities Act, the issuance of the Public Shares issuable upon exercise of the Warrants. The Company will use its best efforts to cause the same to become effective and to maintain the effectiveness of such registration statement, and a current prospectus relating thereto, until the expiration of the Warrants in accordance with the provisions of the applicable Warrant Agreement. Notwithstanding the above, if the Public Shares are at the time of any exercise of a Warrant not listed on a national securities exchange such that it satisfies the definition of a "covered security" under Section 18(b)(1) of the Securities Act, the Company may, at its option, require holders of Warrants who exercise their Warrants to do so on a "cashless basis" in accordance with Section 3(a)(9) of the Securities Act and, in the event the Company so elects, it will not be required to file or maintain in effect a registration statement, but the Company will be required to use its best efforts to register or qualify the shares under applicable blue sky laws to the extent an exemption is not available.

Beginning 30 days after completion of the initial Business Combination, the Company may redeem the outstanding Public Warrants for cash:

• in whole and not in part;

• at a price of $0.01 per Public Warrant;

• upon not less than 30 days' prior written notice of redemption (the "30-day redemption period"); and

• if, and only if, the last sale price of the Class A ordinary shares equals or exceeds $18.00 per share (as adjusted for share subdivisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within a 30 trading day period ending on the third trading day prior to the date on which the Company sends the notice of redemption to the warrant holders. The Company will not redeem the Public Warrants as described above unless a registration statement under the Securities Act covering the Class A ordinary shares issuable upon exercise of the Public Warrants is effective and a current prospectus relating to those Class A ordinary shares is available throughout such 30 trading day period and the 30-day redemption period.

The Private Warrants contained in the Private Placement Units are non-redeemable. The Private Warrants may also be exercised for cash or on a "cashless basis." The Private Warrants will not expire except upon liquidation.

#### Note 8 — Fair Value Measurements
The fair value of the Company's financial assets and liabilities reflects management's estimate of amounts that the Company would have received in connection with the sale of the assets or paid in connection with the transfer of the liabilities in an orderly transaction between market participants at the measurement date. In connection with measuring the fair value of its assets and liabilities, the Company seeks to maximize the use of observable inputs (market data obtained from independent sources) and to minimize the use of unobservable inputs (internal assumptions about how market participants would price assets and liabilities).

------

#### **Table of Contents**

#### CHURCHILL CAPITAL CORP IX

#### NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

#### MARCH 31, 2026
(UNAUDITED)

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.

As of March 31, 2026, assets held in the Trust Account were comprised of $0 in cash and $310,264,509 invested in money market funds.

As of December 31, 2025, assets held in the Trust Account were comprised of $235 in cash and $307,660,577 invested in U.S. Treasury Securities.

Transfers to/from Levels 1, 2 and 3 are recognized at the end of the reporting period in which a change in valuation technique or methodology occurs. There were no transfers for the three months ended March 31, 2026and 2025.

#### Note 9 — Segment Reporting
FASB ASC Topic 280, "Segment Reporting," establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise that engage in business activities from which it may recognize revenues and incur expenses, and for which separate financial information is available that is regularly evaluated by the Chief Operating Decision Maker ("CODM"), or group, in deciding how to allocate resources and assess performance.

The Company's CODM has been identified as the Chief Financial Officer, who reviews the assets, operating results, and financial metrics for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that there is only one reportable segment.

The CODM assesses performance for the single segment and decides how to allocate resources based on net income or loss that also is reported on the accompanying condensed consolidated statements of operations as net income or loss. The measure of segment assets is reported on the accompanying 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:

The CODM reviews interest earned on the Trust Account to measure and monitor shareholder value and determine the most effective strategy of investment with the Trust Account funds while maintaining compliance with the Investment Management Trust Agreement, dated May 1, 2024, by and between the Company and Continental, as trustee.

General and administrative costs are reviewed and monitored by the CODM to manage and forecast cash to ensure enough capital is available to complete a Business Combination or similar transaction within the Combination Period. The CODM also reviews general and administrative costs to manage, maintain and enforce all contractual agreements to ensure costs are aligned with all agreements and budget. General and administrative costs, as reported on the accompanying consolidated statements of operations, are the significant segment expenses provided to the CODM on a regular basis.

All other segment items included in net income or loss are reported on the accompanying condensed consolidated statements of operations and described within their respective disclosures.

#### Note 10 — Subsequent Events
The Company evaluated subsequent events and transactions that occurred after the condensed consolidated balance sheet date up to the date that the unaudited condensed consolidated financial statements were issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the unaudited condensed consolidated financial statements, except as follows.

#### Termination of PlusAI Merger Agreement
On June 5, 2025, the Company entered into the PlusAI Merger Agreement with Merger Sub I, Merger Sub II and PlusAI. On April 20, 2026, the Company and PlusAI entered into the Termination Agreement pursuant to which the PlusAI Merger Agreement was terminated by the mutual consent of the Company and PlusAI, effective as of April 20, 2026, due to market conditions. As a result of the mutual termination of the PlusAI Merger Agreement, that agreement became of no further force and effect, except as set forth in the Termination Agreement. The mutual termination of the PlusAI Merger Agreement also terminated and made void the transaction agreements that were entered into in connection with the PlusAI Merger Agreement.

#### Item 2. Management's Discussion and Analysis of Financial Condition and Results of Operations

#### Cautionary Note Regarding Forward-Looking Statements
All statements other than statements of historical fact included in this Report including, without limitation, statements under this Item regarding our financial position, possible Business Combination and financing thereof and related matters and the plans and objectives of Management for future operations, are forward-looking statements within the meaning of Section 27A of the Securities Act and Section 21 E of the Exchange Act. When used in this Report, words such as "anticipate," "believe," "estimate," "expect," "intend" and similar expressions, as they relate to us or our Management, identify forward-looking statements. We have based these forward-looking statements on our Management's current expectations and projections about future events, as well as assumptions made by, and information currently available to, our Management. Actual results could differ materially from those contemplated by the forward-looking statements as a result of certain factors detailed in our filings with the SEC. All subsequent written or oral forward-looking statements attributable to us or persons acting on our behalf are qualified in their entirety by this paragraph.

The following discussion and analysis of our financial condition and results of operations should be read in conjunction with the unaudited condensed consolidated financial statements and the notes thereto included in this Report under "Item 1. Financial Statements."

#### Overview
We are a blank check company incorporated in the Cayman Islands on December 18, 2023, formed for the purpose of effecting a Business Combination with one or more businesses that we have not yet identified. We intend to effectuate our 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.

Although we are not limited in our search for target businesses to a particular industry or sector for the purpose of consummating the Business Combination, we are focusing our search on a target in an industry where we believe our Management Team and founder's expertise will provide us with a competitive advantage. We are an early stage and emerging growth company and, as such, we are 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. There can be no assurance that our plans to complete a Business Combination will be realized.

Our IPO Registration Statement became effective on May 1, 2024. On May 6, 2024, we consummated our Initial Public Offering of 28,750,000 Units, including 3,750,000 Units issued pursuant to the full exercise of the Over-Allotment Option. Each Unit consists of one Class A Ordinary Share and one-quarter of one Public Warrant. The Units were sold at a price of $10.00 per Unit, generating gross proceeds to us of $287,500,000.

Simultaneously with the closing of the Initial Public Offering and pursuant to the Private Placement Units Purchase Agreement, we completed the sale of 725,000 Private Placement Units to the Sponsor in the private placement at a purchase price of $10.00 per Private Placement Units, generating gross proceeds to us of $7,250,000. The Private Placement Units (and underlying securities) are identical to the Units, except as otherwise disclosed in the IPO Registration Statement.

Following the closing of the Initial Public Offering and Private Placement, an amount of $287,500,000 from the net proceeds of the Initial Public Offering and the Private Placement was initially placed in the Trust Account located in the United States with Continental Stock Transfer & Trust Company acting as trustee. The Trust Account may be invested only (i) in U.S. government securities, within the meaning set forth in Section 2(a)(16) of the Investment Company Act with a maturity of 185 days or less, (ii) any open-ended investment company that holds itself out as a money market fund selected by us meeting the conditions of paragraphs (d)(2), (d)(3) and (d)(4) of Rule 2a-7 of the Investment Company Act, or (iii) as cash or cash items (including in demand deposit accounts) at a bank as determined by us, until the earlier of: (x) the completion of the Business Combination and (y) the distribution of the Trust Account, as described below.

We have until August 6, 2026 (27 months from the closing of the Initial Public Offering), or until such earlier liquidation date as our Board may approve or such later date as our shareholders may approve pursuant to our amended and restated memorandum and articles of association, to consummate the Business Combination. If we are unable to complete the Business Combination by the end of the Combination Period, 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 and not previously released to us to pay taxes, if any, divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders' rights as shareholders (including the right to receive further liquidating distributions, if any), subject to applicable law, and (iii) as promptly as reasonably possible following such redemption, subject to the approval of our remaining shareholders and our Board, dissolve and liquidate, 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 expect to continue to incur significant costs in the pursuit of our acquisition plans. We cannot assure our shareholders that our plans to complete a Business Combination will be successful.

------

We may seek to extend the Combination Period consistent with applicable laws, regulations and stock exchange rules by amending our Amended and Restated Articles. Such an amendment would require the approval of our Public Shareholders, who will be provided the opportunity to redeem all or a portion of their Public Shares in connection with the vote on such approval. Such redemptions will decrease the amount held in our Trust Account and our capitalization and may affect our ability to maintain our listing on Nasdaq. In addition, the Nasdaq rules currently require special purpose acquisition companies (such as us) to complete our initial Business Combination within 36 months following the effective date of our IPO Registration Statement. If we do not meet such 36-month requirement, our securities will likely be subject to a suspension of trading and delisting from Nasdaq.

#### Termination of PlusAI Business Combination Agreement
On June 5, 2025, we entered into the PlusAI Merger Agreement with (i) PlusAI and (ii) the Merger Subs. On April 20, 2026, we and PlusAI entered into a Termination Agreement pursuant to which the PlusAI Merger Agreement was terminated by mutual consent, effective as of April 20, 2026, due to market conditions. As a result of the mutual termination of the PlusAI Merger Agreement, that agreement became of no further force and effect, except as set forth in the Termination Agreement. The mutual termination of the PlusAI Merger Agreement also terminated and made void the transaction agreements that were entered into in connection with the PlusAI Merger Agreement.

In view of the termination of the PlusAI Merger Agreement, we cancelled the extraordinary general meeting of shareholders previously scheduled for 10:00 a.m. Eastern Time on April 24, 2026 and the related redemption deadline.

#### Results of Operations
We have neither engaged in any operations nor generated any revenues to date. Our only activities since December 18, 2023 (inception) through March 31, 2026 have been (i) organizational activities and (ii) activities relating to (x) the Initial Public Offering, (y) identifying and evaluating prospective acquisition candidates and activities in connection with the initial Business Combination and (z) pursuing the then-prospective PlusAI Business Combination. We will not generate any operating revenues until after completion of our initial Business Combination. We have generated non-operating income in the form of interest income on investments held in the Trust Account after the Initial Public Offering. We expect to incur increased expenses as a result of being a public company (for legal, financial reporting, accounting and auditing compliance, among other things), as well as for due diligence expenses.

For the three months ended March 31, 2026, we had net income of $1,493,975, which includes $2,647,110 of interest income earned on Trust Account, offset by $1,153,135 of general and administrative costs.

For the three months ended March 31, 2025, we had net income of $2,714,137, which includes $2,997,592 of interest income earned on Trust Account, offset by $283,455 of general and administrative costs.

#### Liquidity, Capital Resources and Going Concern
Following the Initial Public Offering, including the full exercise of the Over-Allotment Option, and the Private Placement, a total of $287,500,000 was placed in the Trust Account. We incurred fees of $14,560,986 in the Initial Public Offering, consisting of $5,750,000 of cash underwriting fee, the Deferred Fee of $10,062,500 and $557,236 of other offering costs, which was offset by reimbursement from the Underwriters of $1,808,750.

As of March 31, 2026, and December 31, 2025, we had marketable securities and cash held in the Trust Account of $310,264,509 and $307,617,399, respectively (including interest income). We may withdraw interest from the Trust Account to pay taxes, if any, and other Permitted Withdrawals. We intend to use substantially all of the funds held in the Trust Account, including any amounts representing interest earned on the Trust Account (which interest shall be net of taxes payable, if any, and exclude the Deferred Fee), to complete our Business Combination. To the extent that our share capital or debt is used, in whole or in part, as consideration to complete our Business Combination, the remaining proceeds held in the Trust Account will be used as working capital to finance the operations of the target business or businesses, make other acquisitions and pursue our growth strategies.

To mitigate the risk that we might be deemed to be an investment company for purposes of the Investment Company Act, which risk increases the longer that we hold investments in the Trust Account, we may at any time (based on our Management Team's ongoing assessment of all factors related to our potential status under the Investment Company Act) instruct the trustee to liquidate the investments held in the Trust Account and instead to hold the funds in the Trust Account in cash or in an interest-bearing demand deposit account at a bank.

------

As of March 31, 2026 and December 31, 2025, we had cash held outside of the Trust Account of $167,798 and $2,469, respectively. We use the funds held outside the Trust Account primarily to identify and evaluate target businesses, perform business due diligence on prospective target businesses, travel to and from the offices, plants, or similar locations of prospective target businesses or their representatives or owners, review corporate documents and material agreements of prospective target businesses, and structure, negotiate and complete a Business Combination.

Our liquidity needs through March 31, 2026 have been satisfied through (i) a contribution of $25,000 from the Sponsor in exchange for the issuance of our Founder Shares, (ii) Permitted Withdrawals, (iii) loans pursuant to the IPO Promissory Note and the WCL Promissory Note and (iv) the net proceeds from the consummation of the Initial Public Offering and the Private Placement held outside the Trust Account.

#### Permitted Withdrawals
To fund working capital, we have Permitted Withdrawals available from the Trust Account up to an annual limit of $1,000,000. These Permitted Withdrawals are limited to only the interest available that has been earned in excess of the initial deposit in the Trust Account at the Initial Public Offering. During the year ended December 31, 2024, we withdrew $1,000,000 in interest for working capital purposes pursuant to Permitted Withdrawals and had no further amounts available for Permitted Withdrawals until May 6, 2025, which was the one-year anniversary of the Initial Public Offering. For the year ended December 31, 2025, we withdrew another $1,000,000 in interest from the Trust Account for working capital purposes pursuant to Permitted Withdrawals and have no further amounts available for permitted withdrawals until May 6, 2026, which is the two-year anniversary of the Initial Public Offering.

#### Working Capital Loans
In order to fund working capital deficiencies or finance transaction costs in connection with a Business Combination, the Sponsor or an affiliate of the Sponsor, or certain of our officers and directors may, but are not obligated to, loan us Working Capital Loans, as may be required. If we complete a Business Combination, we will repay such Working Capital Loans. In the event that a Business Combination does not close, we may use a portion of the working capital held outside the Trust Account to repay such Working Capital Loans, but no proceeds from our Trust Account would be used for such repayment. If the Sponsor or its assigns or successors makes any Working Capital Loans, up to $1,500,000 of such Working Capital Loans may be converted into WCL Conversion Units at a price of $10.00 per unit at the option of the lender. The units (and underlying securities) would be identical to the Private Placement Units (and underlying securities).

On December 2, 2025, we issued the WCL Promissory Note in the aggregate principal amount of up to $1,500,000 to the Sponsor, for any Working Capital Loans the Sponsor may make to us. The WCL Promissory Note does not bear interest and matures upon the earlier of the closing of an initial Business Combination and our liquidation. Amounts outstanding under the WCL Promissory Note are convertible, at the option of the Sponsor, into WCL Conversion Units, at a conversion price of $10.00 per WCL Conversion Unit, with each WCL Conversion Unit consisting of Class A Ordinary Share and one-quarter of one warrant, with each whole warrant exercisable for one Class A Ordinary Share at $11.50 per share, subject to adjustment as provided in the IPO Registration Statement. Any WCL Conversion Units (and underlying securities) will be identical to the Private Placement Units (and underlying securities). The WCL Conversion Units are entitled to registration rights.

As of March 31, 2026, and December 31, 2025, the Company borrowed $500,000 and $0, respectively, under the WCL Promissory Note. As of March 31, 2026, the Company has $1,000,000 available under the WCL Promissory Note.

#### Going Concern
In connection with our assessment of going concern considerations in accordance with FASB ASC Topic 205-40, "Presentation of Financial Statements—Going Concern", Management has determined that we currently lack the liquidity we need to sustain operations for a reasonable period of time, which is considered to be at least one year from the date that the consolidated financial statements and the notes thereto included elsewhere in this Report are issued, as we expect to continue to incur significant costs in pursuit of our acquisition plans. In addition, Management has determined that if we are unable to complete an initial Business Combination within the Combination Period, then we will cease all operations except for the purpose of liquidating. These conditions raise substantial doubt about our ability to continue as a going concern. Management plans to consummate an initial Business Combination prior to the end of the Combination Period. No adjustments have been made to the carrying amounts of assets or liabilities should we be required to liquidate after August 6, 2026. We intend to complete a Business Combination before the end of the Combination Period; however, there can be no assurance that our plans to raise capital or to consummate an initial Business Combination will be successful.

------

#### Contractual Obligations
We do not have any long-term debt, capital lease obligations, operating lease obligations or long-term liabilities, other than as follows:

#### Administrative Support Agreement
The Company entered into an agreement, commencing on May 2, 2024, that the Company will reimburse an affiliate of the Sponsor in an amount equal to $30,000 per month for office space, utilities and secretarial and administrative support. Upon completion of the initial Business Combination or the Company's liquidation, the Company will cease paying these monthly fees. For the three months ended March 31, 2026, the Company incurred and accrued $90,000 in fees which is included within accrued expenses on the accompanying condensed consolidated balance sheets. For the three months ended March 31, 2025, the Company incurred and paid $90,000 for these services.

*Underwriting Agreement*

We granted the Underwriters a 45-day option from the date of the Initial Public Offering to purchase up to an additional 3,750,000 Option Units to cover over-allotments, if any. On May 6, 2024, the Underwriters fully exercised their Over-Allotment Option.

The Underwriters were paid a cash underwriting discount of $5,750,000 (2.0% of the gross proceeds of the Public Units offered in the Initial Public Offering (including the Option Units)). In addition, the Underwriters agreed to reimburse us for certain expenses in connection with the Initial Public Offering. On May 6, 2024, we received a reimbursement from the Underwriters of $1,808,750 at the Initial Public Offering.

Additionally, the Underwriters are entitled to the Deferred Fee of 3.50% of the gross proceeds of the base Initial Public Offering held in the Trust Account, which equates to $10,062,500 in the aggregate following the full exercise of the Over-Allotment Option and is payable to the Underwriters upon the completion of the initial Business Combination subject to the terms of the Underwriting Agreement.

*Advisory Agreement* 

On June 4, 2025, we entered into an advisory agreement (the "Advisory Agreement") with Citigroup Global Markets Inc., representative of the Underwriters (the "Advisor"), to provide capital market advisory services in connection with the completion of the PlusAI Business Combination. Following the termination of the PlusAI Merger Agreement, Churchill terminated the Advisory Agreement in accordance with its terms. The Advisor is not entitled to any cash fee as a result of the termination.

*Registration Rights Agreement* 

The holders of the (i) Founder Shares, (ii) Private Placement Units and (iii) WCL Conversion Units, if any (and in each case holders of their underlying securities, as applicable) are entitled to registration rights pursuant to the Registration Rights Agreement, requiring us to register such securities for resale (in the case of the Founder Shares, only after conversion to our Class A Ordinary Shares). The holders of the majority of these securities are entitled to make up to three demands, excluding short form demands, that we register such securities. In addition, the holders have certain "piggyback" registration rights with respect to registration statements filed subsequent to the consummation of a Business Combination and rights to require us to register for resale such securities pursuant to Rule 415 under the Securities Act. We will bear the expenses incurred in connection with the filing of any such registration statements.

*Letter Agreement* 

Our Sponsor, directors and officers have entered into the Letter Agreement with us, pursuant to which, they have waived their rights to liquidating distributions from the Trust Account with respect to any Founder Shares held by them if we fail to complete our initial Business Combination within the Combination Period. However, if they acquire Public Shares in or after the Initial Public Offering, they will be entitled to liquidating distributions from the Trust Account with respect to such Public Shares if we fail to complete our initial Business Combination within the Combination Period.

Additionally, pursuant to the Letter Agreement, our Sponsor, directors and officers will not propose any amendment to our Amended and Restated Articles to modify (i) the substance or timing of our obligation to allow redemption in connection with our initial Business Combination or to redeem 100% of our Public Shares if we do not complete our initial Business Combination within the Combination Period or (ii) any other material provisions relating to shareholders' rights or pre-initial Business Combination activity, unless we provide our Public Shareholders with the opportunity to redeem their Public Shares upon approval of any such amendment at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest earned on the funds held in the Trust Account and not previously released to us to pay our taxes, divided by the number of then outstanding Public Shares.

Furthermore, pursuant to the Letter Agreement, our Sponsor, directors, officers have agreed that: (x) the Founder Shares shall be subject to a transfer restrictions of the earlier of (i) six months after the completion of our initial Business Combination and (ii) the date following the completion of our initial Business Combination on which we complete a liquidation, merger, share exchange or other similar transaction that results in all of our shareholders having the right to exchange their Class A Ordinary Shares for cash, securities or other property; and (y) the Private Placement Units (including their underlying securities) shall be subject to transfer restriction until 30 days after the completion of our initial Business Combination.

------

*Director Agreements* 

On July 30, 2025, the Company entered into a Director Agreement with each of the three independent directors of the Company, pursuant to which, in connection with each director's continuing service as a director of the Company, the Company agreed to pay each director a cash compensation of $75,000 per annum, beginning on the later of their date of appointment and April 1, 2025. For the three months ended March 31, 2026, the Company incurred $56,250 in fees related to the Director Agreements, and $56,250 is included in accrued expenses within the condensed consolidated balance sheets as of March 31, 2026 and December 31, 2025, respectively. For the three months ended March 31, 2025, the Company did not incur any fees related to the Director Agreements.

*Legal and Due Diligence Fees* 

On April 22, 2025, we entered into an agreement for legal services. All fees related to the agreement are contingent upon the completion of a Business Combination. Upon the completion of the Business Combination, in addition to payment of incurred fees, we will pay a premium ranging from 50% to 100% of the fees incurred, with the percentage paid to be determined at our discretion. As of March 31, 2026 and December 31, 2025, we had incurred approximately $4,570,000 and $3,420,000 of fees, respectively, in connection with such agreement. These fees are not reflected in the consolidated financial statements included elsewhere in this Report and will be recorded when the Business Combination is considered probable.

On May 2, 2025, we entered into an agreement for due diligence services. The total fee related to the due diligence services was $1,050,000, of which $900,000 was paid and included in the consolidated statements of operations of the consolidated financial statements included elsewhere in this Report. The remaining $150,000 is subject to customer satisfaction and due upon the consummation of a Business Combination. The remaining amount is not reflected in the consolidated financial statements included elsewhere in this Report.

#### Critical Accounting Estimates and Policies
The preparation of condensed consolidated financial statements in conformity with GAAP 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 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 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, actual results could materially differ from those estimates. As of March 31, 2026 and December 31, 2025, we did not have any critical accounting estimates to be disclosed.

#### Recent Accounting Standards
In November 2024, the FASB issued ASU 2024-03, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Disaggregation of Income Statement Expenses ("ASU 2024-03"), and in January 2025, the FASB issued ASU 2025-01, Income Statement - Reporting Comprehensive Income - Expense Disaggregation Disclosures (Subtopic 220-40): Clarifying the Effective Date ("ASU 2025-01"). ASU 2024-03 requires additional disclosure of the nature of expenses included in the income statement as well as disclosures about specific types of expenses included in the expense captions presented in the income statement. ASU 2024-03, as clarified by ASU 2025-01, is effective for fiscal years beginning after December 15, 2026, and interim periods within fiscal years beginning after December 15, 2027, with early adoption permitted. The Company is currently evaluating the impact these standards will have on it unaudited condensed financial statements.

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

#### Item 3. Quantitative and Qualitative Disclosures About Market Risk
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 4. Controls and Procedures

#### Evaluation of Disclosure Controls and Procedures
Disclosure controls and procedures are designed with the objective of ensuring that information required to be disclosed in our reports filed under the Exchange Act, such as this Report, is recorded, processed, summarized, and reported within the time periods specified in the SEC's rules and forms. Disclosure controls and procedures are also designed with the objective of ensuring that such information is accumulated and communicated to our Management, including our Certifying Officers, as appropriate, to allow timely decisions regarding required disclosure. Under the supervision and with the participation of our Management, including our Certifying Officers, we carried out an evaluation of the effectiveness of the design and operation of our disclosure controls and procedures as defined in Rules 13a-15(e) and 15d-15(e) under the Exchange Act. Based on the foregoing, our Certifying Officers concluded that our disclosure controls and procedures were effective as of the end of the fiscal quarter ended March 31, 2026.

------

We do not expect that our disclosure controls and procedures will prevent all errors and all instances of fraud. Disclosure controls and procedures, no matter how well conceived and operated, can provide only reasonable, not absolute, assurance that the objectives of the disclosure controls and procedures are met. Further, the design of disclosure controls and procedures must reflect the fact that there are resource constraints, and the benefits must be considered relative to their costs. Because of the inherent limitations in all disclosure controls and procedures, no evaluation of disclosure controls and procedures can provide absolute assurance that we have detected all our control deficiencies and instances of fraud, if any. The design of disclosure controls and procedures also is based partly on certain assumptions about the likelihood of future events, and there can be no assurance that any design will succeed in achieving its stated goals under all potential future conditions.

#### Changes in Internal Control over Financial Reporting
There was no change in our internal control over financial reporting that occurred during the quarterly period ended March 31, 2026 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
To the knowledge of our management team, there is no material litigation currently pending or contemplated against us, any of our subsidiaries, or any of our officers or directors in their capacity as such or against any of our property.

#### Item 1A. Risk Factors
As a smaller reporting company under Rule 12b-2 of the Exchange Act, we are not required to include risk factors in the Report. However, for detailed descriptions of the risks relating to our Company, see the section titled "Risk Factors" contained in our (i) IPO Registration Statement, (ii) 2025 Annual Report and (iii) Quarterly Reports on Form 10-Q for the quarterly periods ended September 30, 2025, June 30, 2025, March 31, 2025, as filed with the SEC on November 11, 2025, August 13, 2025 and May 13, 2025, respectively. As of the date of the Report, there have been no material changes with respect to those risk factors , other than as set forth below. Any of these previously disclosed risk factors could result in a significant or material adverse effect on our results of operations or financial condition. Additional risks not presently known to us or that we currently deem immaterial may also affect our ability to consummate an initial Business Combination. We may disclose changes to such risk factors or disclose additional risk factors from time to time in our future filings with the SEC.

**Delays in the government budget process or a government shutdown may materially adversely affect our ability to complete our initial Business Combination, or the operations of the post-closing company following our initial Business Combination.** 

Each year, the U.S. Congress must pass all spending bills in the federal budget. If any such spending bill is not timely passed, a government shutdown will close many federally run operations, which includes those of the SEC, and halt work for federal employees unless they are considered essential. If a government shutdown occurs (which it has since October 1, 2025), and the SEC remains closed for a prolonged period of time, we may not be able to complete our initial Business Combination, particularly if the SEC is unable to timely review our filings, or those of a target business or other entity that relate to our initial Business Combination, or to declare such filings effective to the extent required or as may be applicable. Additionally, following consummation of our initial Business Combination, the post-closing company's operations or its ability to raise additional capital to support its operations could be materially adversely affected by any prolonged government shutdown.

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

#### Unregistered Sales of Equity Securities
There were no sales of unregistered securities during the quarterly period covered by this Report.

#### Use of Proceeds
There have been no offerings of registered securities and therefore no planned use of proceeds from such offerings during the quarterly period covered by this Report. For a description of the use of the proceeds generated in the Initial Public Offering, see Part II, Item 2 of our Report on Form 10-Q for the quarterly period ended March 31, 2024, as filed with the SEC on June 7, 2024. There has been no material change in the planned use of proceeds from our Initial Public Offering and Private Placement as described in the IPO Registration Statement. The specific investments in our Trust Account may change from time to time.

#### Item 3. Defaults Upon Senior Securities
None.

#### Item 4. Mine Safety Disclosures
Not applicable.

#### Item 5. Other Information

#### Trading Arrangements
During the quarterly period ended March 31, 2026, none of our directors or officers (as defined in Rule 16a-1(f) promulgated under the Exchange Act) adopted or terminated any "Rule 10b5-1 trading arrangement" or any "non-Rule 10b5-1 trading arrangement," as each term is defined in Item 408(a) of Regulation S-K.

internal control over financial reporting; and

5. The registrant's other certifying officer and I have disclosed, based on our most recent evaluation of

financial reporting which are reasonably likely to adversely affect the registrant's ability to record, process, summarize and report financial information; and

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;b) Any fraud, whether or not material, that involves management or other employees who have a significant role in
the registrant's internal control over financial reporting.
