Opinion on the Financial Statement

We have audited the accompanying balance sheet of Thayer Ventures Acquisition Corporation II (the “Company”) as of May 16, 2025, and the related notes (collectively referred to as the “financial statement”). In our opinion, the financial statement presents fairly, in all material respects, the financial position of the Company as of May 16, 2025, in conformity with accounting principles generally accepted in the United States of America.

Basis for Opinion

This financial statement is the responsibility of the Company’s management. Our responsibility is to express an opinion on the Company’s financial statement based on our audit. We are a public accounting firm registered with the Public Company Accounting Oversight Board (United States) (“PCAOB”) and are required to be independent with respect to the Company in accordance with the U.S. federal securities laws and the applicable rules and regulations of the Securities and Exchange Commission and the PCAOB.

We conducted our audit in accordance with the standards of the PCAOB. Those standards require that we plan and perform the audit to obtain reasonable assurance about whether the financial statement is free of material misstatement, whether due to error or fraud. The Company is not required to have, nor were we engaged to perform, an audit of its internal control over financial reporting.

Such procedures included examining, on a test basis, evidence regarding the amounts and disclosures in the financial statement. Our audit also included evaluating the accounting principles used and significant estimates made by management, as well as evaluating the overall presentation of the financial statement. We believe that our audit provides a reasonable basis for our opinion.

NOTES TO FINANCIAL STATEMENT

May 16, 2025

Note 1 — Description of Organization and Business Operations

Thayer Ventures Acquisition Corporation II (the “Company”) is a blank check company incorporated as a Cayman Islands exempt company on April 23, 2024. The Company was formed for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”). The Company is an emerging growth company and, as such, the Company is subject to all of the risks associated with emerging growth companies.

As of May 16, 2025, the Company had not commenced any operations. All activity for the period from April 23, 2024 (inception) through May 16, 2025 relates to the Company’s formation and the initial public offering (the “Initial Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of its initial Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income on the proceeds derived from the Initial Public Offering. The Company has selected December 31 as its fiscal year end.

The registration statement for the Company’s Initial Public Offering was declared effective on May 14, 2025. On May 16, 2025, the Company consummated the Initial Public Offering of 20,125,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”), which includes the full exercise by the underwriters of their over-allotment option in the amount of 2,625,000 Units, at $10.00 per Unit, generating gross proceeds of 201,250,000. Each Unit consists of one Public Share and one right (“Right”) to receive one tenth (1/10) of a Class A ordinary share upon the consummation of an initial Business Combination (“Public Right”).

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of 362,500 units (the “Private Placement Units”) at a price of $10.00 per Private Placement Unit, in a private placement to the Company’s sponsor, Thayer Ventures Acquisition Holdings II LLC, a Delaware limited liability company (the “Sponsor”), generating gross proceeds of $3,625,000. Each Private Placement Unit consists of one Private Placement Share and one Right to receive one tenth (1/10) of a Class A ordinary share upon the consummation of an initial Business Combination (“Private Placement Right”).

Transaction costs amounted to $10,727,318, consisting of $1,500,000 of cash underwriting fee (net of $2,000,000 underwriters’ reimbursement), $7,568,750 of deferred underwriting fee, and $1,658,568 of other offering costs.

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

Following the closing of the Initial Public Offering, on May 16, 2025, an amount of $201,250,000 ($10.00 per Unit) from the net proceeds of the sale of the Units and the Private Placement Units was placed in the trust account (the “Trust Account”), with Continental Stock Transfer & Trust Company acting as trustee. The funds are initially to be held in cash, including demand deposit accounts at a bank, or invested only in U.S. government treasury obligations with a maturity of 185 days or less or in money market funds meeting certain conditions under Rule 2a-7 under the Investment Company Act which invest only in direct U.S. government treasury obligations, as determined by the Company, until the earlier of (i) the completion of a Business Combination and (ii) the distribution of the Trust Account as described below.

The Company will provide the holders (the “Public Shareholders”) of the Company’s outstanding shares of Class A ordinary shares, par value $0.0001 per share, sold in the Initial Public Offering (the “Public Shares”) with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a shareholder meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company, solely in its discretion. The Public Shareholders will be entitled to redeem their Public Shares for a pro rata portion of the amount then held in the Trust Account (initially anticipated to be $10.00 per Public Share). The per-share amount to be distributed to Public Shareholders who redeem their

F-4

Public Shares will not be reduced by the deferred underwriting commissions the Company will pay to the underwriter (as discussed in Note 5). These Public Shares subject to possible redemption were classified as temporary equity upon the completion of the Initial Public Offering in accordance with Financial Accounting Standards Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” If the Company seeks shareholder approval, the Company will proceed with a Business Combination if a majority of the shares voted are voted in favor of the Business Combination. The Company will not redeem the Public Shares in connection with a Business Combination in an amount that would cause its net tangible assets to be less than $5,000,001. If a shareholder vote is not required by law and the Company does not decide to hold a shareholder vote for business or other legal reasons, the Company will, pursuant to its amended and restated Certificate of Incorporation (the “Certificate of Incorporation”), conduct the redemptions pursuant to the tender offer rules of the U.S. Securities and Exchange Commission (“SEC”) and file tender offer documents with the SEC prior to completing a Business Combination. If, however, shareholder approval of the transaction is required by law, or the Company decides to obtain shareholder approval for business or legal reasons, the Company will offer to redeem shares in conjunction with a proxy solicitation pursuant to the proxy rules and not pursuant to the tender offer rules.

Additionally, each Public Shareholder may elect to redeem their Public Shares irrespective of whether they vote for or against the proposed transaction or do not vote at all or are not a holder of record of Public Shares on the record date established in connection with a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the initial shareholders (as defined below) will agree to vote their Founder Shares (as defined below in Note 4) and any Public Shares purchased during or after the Initial Public Offering in favor of a Business Combination. In addition, the initial shareholders will agree to waive their redemption rights with respect to their Founder Shares and Public Shares in connection with the completion of a Business Combination.

The Amended and Restated memorandum and articles of association provides that a Public Shareholder, together with any affiliate of such shareholder or any other person with whom such shareholder is acting in concert or as a “group” (as defined under Section 13 of the Exchange Act), will be restricted from redeeming its shares with respect to more than an aggregate of 15% or more of the Public Shares, without the prior consent of the Company.

The holders of the Founder Shares (the “initial shareholders”) will agree not to propose an amendment to the Articles of Association to modify the substance or timing of the Company’s obligation to redeem 100% of the Public Shares if the Company does not complete a Business Combination within the Combination Period (as defined below) or with respect to any other material provisions relating to shareholders’ rights or pre-initial Business Combination activity, unless the Company provides the Public Shareholders with the opportunity to redeem their Public Shares in conjunction with any such amendment.

If the Company is unable to complete a Business Combination within 21 months from the closing of the Initial Public Offering (the “Combination Period”), the Company will (i) cease all operations except for the purpose of winding up; (ii) as promptly as reasonably possible, but not more than ten business days thereafter, redeem the Public Shares, at a per-share price, payable in cash, equal to the aggregate amount then on deposit in the Trust Account, including interest (which interest shall be net of permitted withdrawals, including for taxes payable, and up to $100,000 of interest to pay dissolution expenses), divided by the number of then outstanding Public Shares, which redemption will completely extinguish Public Shareholders’ rights as shareholders (including the right to receive further liquidating distributions, if any); and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the board of directors, liquidate and dissolve, subject in each case, to the Company’s obligations under Cayman law to provide for claims of creditors and the requirements of other applicable law.

The initial shareholders agreed to waive their rights to liquidating distributions from the Trust Account with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the initial shareholders 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 the Company fails to complete a Business Combination within the Combination Period. The underwriter agreed to waive its rights to the deferred underwriting commission (see Note 5) held in the Trust Account in the event the Company does not complete a Business Combination within in the Combination Period and, in such event, such amounts will be included with the other funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the residual assets remaining available for distribution (including Trust Account assets) will be only $10.00. In order to protect the amounts held in the Trust Account, the Sponsor agreed to be liable to the Company if and to the extent any claims by a third party (except for the Company’s independent registered public accounting firm) for services rendered or products sold to the Company, or a prospective target business with which the Company has entered into a letter of intent, confidentiality or other similar agreement or Business Combination agreement (a “Target”), reduce the amount of funds in the Trust Account to below the lesser of (i) $10.00 per Public Share and (ii) the actual amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account, if less than $10.00 per Public Share due to reductions in the value of the trust assets, less permitted withdrawals, provided that such liability will not apply to any claims by a third party or

F-5

prospective target business who executed a waiver of any and all rights to the monies held in the Trust Account (whether or not such waiver is enforceable) nor will it apply to any claims under the Company’s indemnity of the underwriter of this offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (excluding the Company’s independent registered public accounting firm), prospective target businesses or other entities with which the Company does business, execute agreements with the Company waiving any right, title, interest or claim of any kind in or to monies held in the Trust Account.

Note 2 — Summary of Significant Accounting Policies

Basis of Presentation

The accompanying financial statement is presented in conformity with accounting principles generally accepted in the United States of America (“U.S. GAAP”) and pursuant to the rules and regulations of the U.S. Securities and Exchange Commission (the “SEC”).

Liquidity and Capital Resources

The Company’s liquidity needs up to May 16, 2025 had been satisfied through the loan under an unsecured promissory note from the Sponsor of up to $400,000 (see Note 4). At May 16, 2025, the Company had no cash and had working capital of $899,432.

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 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 a Business Combination, the Company would repay such loaned amounts at that time. Up to $1,500,000 of such Working Capital Loans may be converted into units of the post-Business Combination entity at a price of $10.00 per unit. The units would be identical to the Private Placement Units. As of May 16, 2025, the Company had no borrowings under the Working Capital Loans.

In connection with the Company’s assessment of going concern considerations in accordance with Accounting Standards Codification (“ASC”) 204-50, “Presentation of Financial Statements - Going Concern,” the Company does not believe it will need to raise additional funds in order to meet the expenditures required for operating its business. However, if the estimate of the costs of identifying a target business, undertaking in-depth due diligence and negotiating a Business Combination are less than the actual amount necessary to do so, the Company may have insufficient funds available to operate its business prior to the initial Business Combination. Management has determined that the Company has access to funds from the Sponsor to finance the working capital needs of the Company within one year from the date of issuance of the financial statement.

Emerging Growth Company

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

Further, Section 102(b)(1) of the JOBS Act exempts emerging growth companies from being required to comply with new or revised financial accounting standards until private companies (that is, those that have not had a Securities Act registration statement declared effective or do not have a class of securities registered under the Exchange Act) are required to comply with the new or revised financial accounting standards. The JOBS Act provides that an emerging growth 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 an 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 financial statement with another public company that 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.

F-6

Use of Estimates

The preparation of financial statement in conformity with U.S. 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 financial statement.

Making estimates requires management to exercise significant judgment. It is at least reasonably possible that the estimate of the effect of a condition, situation or set of circumstances that existed at the date of the financial statement, which management considered in formulating its estimate, could change in the near term due to one or more future confirming events. Accordingly, the actual results could differ significantly from those estimates.

Cash and Cash Equivalents

The Company considers all short-term investments with an original maturity of three months or less when purchased to be cash equivalents. The Company had no cash or cash equivalents as of May 16 ,2025.

Cash Held in Trust Account

As of May 16, 2025, the assets held in the Trust Account, amounting to $201,250,000, were held in demand deposits.

Concentration of Credit Risk

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

Offering Costs

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

Fair Value of Financial Instruments

The fair value of the Company’s assets and liabilities, which qualify as financial instruments under FASB ASC 820, “Fair Value Measurements and Disclosures,” approximates the carrying amounts represented in the balance sheet, primarily due to their short-term nature.

Income Taxes

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

F-7

ASC Topic 740 prescribes a recognition threshold and a measurement attribute for the financial statement recognition and measurement of tax positions taken or expected to be taken in a tax return. For those benefits to be recognized, a tax position must be more likely than not to be sustained upon examination by taxing authorities. The Company’s management determined that the Cayman Islands is the Company’s major tax jurisdiction. The Company recognizes accrued interest and penalties related to unrecognized tax benefits as income tax expense. As of May 16, 2025, there were no unrecognized tax benefits and no amounts accrued for interest and penalties. The Company is currently not aware of any issues under review that could result in significant payments, accruals or material deviation from its position.

The Company is considered to be an exempted Cayman Islands company with no connection to any other taxable jurisdiction and is presently not subject to income taxes or income tax filing requirements in the Cayman Islands or the United States. As such, the Company’s tax provision was zero for the period presented.

Share Rights

The Company accounts for the Public and Private Rights 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 Rights under equity treatment at their assigned value.

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 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 value. The change in the carrying value of redeemable shares will result in charges against additional paid-in capital (to the extent available) and accumulated deficit. Accordingly, as of May 16, 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 balance sheet. As of May 16, 2025, the Class A ordinary shares subject to possible redemption reflected in the balance sheet are reconciled in the following table:


Gross proceeds	$	201,250,000
Less:
Proceeds allocated to Share Rights		(4,025,000	)
Class A ordinary shares issuance costs		(10,484,012	)
Plus:
Remeasurement of carrying value to redemption value		14,509,012

Class A Ordinary Shares subject to possible redemption, May 16, 2025	$	201,250,000

Recent Accounting Standards

In November 2023, the FASB issued Accounting Standards Update (“ASU”) 2023-07, “Segment Reporting (Topic 280): Improvements to Reportable Segment Disclosures.” The amendments in this ASU require disclosures, on an annual and interim basis, of significant segment expenses that are regularly provided to the chief operating decision maker (“CODM”), as well as the aggregate amount of other segment items included in the reported measure of segment profit or loss. The ASU requires that a public entity disclose the title and position of the CODM and an explanation of how the CODM uses the reported measure(s) of segment profit or loss in assessing segment performance and deciding how to allocate resources. Public entities will be required to provide all annual disclosures currently required by Topic 280 in interim periods, and entities with a single reportable segment are required to provide all the disclosures required by the amendments in this ASU and existing segment disclosures in Topic 280. This ASU is effective for fiscal years beginning after December 15, 2023, and interim periods within fiscal years beginning after December 15, 2024, with early adoption permitted. The Company adopted ASU 2023-07 on April 23, 2024, date of incorporation.

The Company’s management does not believe that any recently issued, but not yet effective, accounting standards updates, if currently adopted, would have a material effect on the accompanying financial statement.

F-8

Note 3 — Initial Public Offering

Pursuant to the Initial Public Offering on May 16, 2025, the Company sold 20,125,000 Units, which includes the full exercise by the underwriters of their over-allotment option in the amount of 2,625,000 Units, at a price of $10.00 per Unit. Each Unit consists of one Class A ordinary share and one Public Right. Each Public Right entitles the holder to receive one-tenth of one Class A ordinary share (see Note 6).

Note 4 — Related Party Transactions

Founder Shares

On May 6, 2024, the Company issued 3,593,750 Class B ordinary shares to the Sponsor for $25,000, or approximately $0.007 per share. On September 9, 2024, in connection with a recapitalization, the Company amended the terms of the subscription agreement to issue the Sponsor an additional 2,156,250 Founder Shares for no additional consideration, following which the Sponsor held 5,750,000 Founder Shares. On January 28, 2025, the Company further amended the terms of the subscription agreement, following which the Sponsor holds 5,031,250 Founder Shares. On March 11, 2025, the Company further amended the terms of the subscription agreement, following which the Sponsor holds 6,708,333 Founder Shares. All share amounts have been retroactively restated to reflect this adjustment. The initial shareholders agreed to forfeit up to 875,000 Founder Shares to the extent that the over-allotment option is not exercised in full by the underwriter. The forfeiture will be adjusted to the extent that the over-allotment option is not exercised in full by the underwriter so that the Founder Shares will represent 20.0% of the Company’s issued and outstanding shares after the Initial Public Offering. If the Company increases or decreases the size of the offering, the Company will effect a capitalization of reserves or share surrender back to capital, or other appropriate recapitalization mechanism as applicable, immediately prior to the consummation of the Initial Public Offering so as to maintain the ownership of the initial shareholders at 20.0% of the Company’s issued and outstanding ordinary shares upon the consummation of the Initial Public Offering. On May 16, 2025, the underwriters exercised their over-allotment option in full as part of the closing of the Initial Public Offering. As such, the 875,000 Founder Shares are no longer subject to forfeiture. The Sponsor is holding 6,583,333 Founder Shares, after giving effect to the Founder Share transfers described below.

In March and April 2025, the Sponsor transferred a total of 125,000 Founder Shares to the five independent directors (25,000 each) for an aggregate consideration of $0.004 per share, or an aggregate total amount of $466. The transfer of the Founder Shares to the independent director nominees are in the scope of FASB ASC Topic 718, “Compensation-Stock Compensation” (“ASC 718”). Under ASC 718, stock-based compensation associated with equity-classified awards is measured at fair value upon the assignment date. The fair value of the 125,000 Founder Shares granted to the Company’s independent directors on their respective grant dates in March and April 2025 has an aggregate total of $181,250, or $1.45 per share. The transfer of Founder Shares has no service restrictions, thus, the total fair value of $181,250 was recorded as compensation expense on the respective grant dates in March and April 2025. The fair value of the Founder Shares was derived through a third party valuation in which the implied share price of $9.83 is multiplied by the market adjustment of 17.0%, less a discount for lack of marketability of $0.22.

The initial shareholders agreed, subject to limited exceptions, not to transfer, assign or sell any of the Founder Shares until the earlier to occur of: (A) one year after the completion of the initial Business Combination or (B) subsequent to the initial Business Combination, (x) if the last reported sale price of the Class A ordinary shares equals or exceeds $12.00 per share (as adjusted for subdivisions, share dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the initial Business Combination, or (y) the date on which the Company completes a liquidation, merger, share exchange, reorganization or other similar transaction that results in all of the shareholders having the right to exchange their Class A ordinary shares for cash, securities or other property. Any permitted transferees will be subject to the same restrictions and other agreements of the initial shareholders with respect to any Founder Shares.

Private Placement Units

Simultaneously with the closing of the Initial Public Offering, the Sponsor purchased an aggregate of 362,500 Private Placement Units at a price of $10.00 per Private Placement Unit, or $3,625,000 in the aggregate, in a private placement. Private Placement Units are the units issued to the Sponsor in a private placement that occurred simultaneously with the Closing of the Initial Public Offering and upon the conversion of Working Capital Loans (as defined below), if any. Each Private Placement Unit consists of one Class A ordinary share and one Private Right. A Private Right entitles the Sponsor to receive one-tenth of one Class A Ordinary Share. The Private Rights have terms and provisions that will be identical to those of the Rights sold as part of the Initial Public Offering.

The purchasers of the Private Placement Units agreed, subject to limited exceptions, not to transfer, assign or sell any of their Private Placement Units (except to permitted transferees) until 30 days after the completion of the initial Business Combination.

Related Party Loans

On May 6, 2024, the Sponsor agreed to loan the Company an aggregate of up to $400,000 to cover expenses related to the Initial Public Offering pursuant to a promissory note (the “Note”). This loan is non-interest bearing and payable on the earlier of the completion of the Initial Public Offering or the date the Company determines not to conduct an Initial Public Offering. As of May 16, 2025, the Company had $158,864 outstanding under the Note from the Sponsor, which is now due on demand.

F-9

In addition, in order to finance transaction costs in connection with a 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 a Business Combination, the Company would repay the Working Capital Loans out of the proceeds of the Trust Account released to the Company. Otherwise, the Working Capital Loans would be repaid only out of funds held outside the Trust Account. In the event that a Business Combination does not close, the Company may use a portion of the 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. The Working Capital Loans would either be repaid upon consummation of a Business Combination or, at the lender’s discretion, up to $1.5 million of such Working Capital Loans may be convertible into units of the post-Business Combination entity at a price of $10.00 per unit. The units would be identical to the Private Units. Except for the foregoing, the terms of such Working Capital Loans, if any, have not been determined and no written agreements exist with respect to such loans. As of May 16, 2025, the Company had no borrowings under the Working Capital Loans.

Due from Sponsor

As of May 16, 2025, the Sponsor owes the Company an aggregate amount of $2,125,000, representing the Private Placement Unit purchase by the Sponsor to be wired once the Company’s bank account has been established.

Consulting Fees

The Company owes Thayer Ventures Management Co, LLC, an affiliate of the Sponsor, an aggregate amount of $200,000 for general consulting services, which was included in accrued expenses line in the accompanying balance sheet.

Administrative Services Agreement

The Company entered into an agreement with the Sponsor, commencing on May 14, 2025 through the earlier of the Company’s consummation of initial Business Combination and its liquidation, to pay the Sponsor an aggregate of $30,000 per month for office space, secretarial and administrative services.

The Sponsor, executive officers and directors, or any of their respective affiliates, will be reimbursed for any out-of-pocket expenses incurred in connection with activities on the Company’s behalf such as identifying potential target businesses and performing due diligence on suitable Business Combinations. The Company’s audit committee will review on a quarterly basis all payments that were made by the Company to the Sponsor, executive directors or officers, or the Company’s or any of their respective affiliates.

Note 5 — Commitments and Contingencies

Registration Rights

The holders of the Founder Shares, private units (including the securities contained therein) and units (including securities) are entitled to registration rights pursuant to a registration rights agreement to be signed prior to or on the effective date of the Initial Public Offering. The holders of these securities are entitled to make unlimited demands that the Company register such securities. In addition, the holders have certain piggyback registration rights with respect to registration statements filed subsequent to the completion of the initial Business Combination. However, the registration rights agreement provides that the Company will not permit any registration statement filed under the Securities Act to become effective until termination of the applicable lock-up period, which occurs (i) in the case of the Founder Shares, and (ii) in the case of the private units and the respective Class A ordinary shares underlying such units, 30 days after the completion of the initial Business Combination. The Company will bear the expenses incurred in connection with the filing of any such registration statements.

Underwriting Agreement

The underwriter has a 45-day option from the date of the Initial Public Offering to purchase up to an additional 2,625,000 Units to cover over-allotments, if any. On May 16, 2025, the underwriters elected to fully exercise their over-allotment option to purchase an additional 2,625,000 Units at a price of $10.00 per Unit.

The underwriter was entitled to a cash underwriting discount of $3,500,000 in the aggregate, or 2.0% of the gross proceeds of the units offered in the Initial Public Offering, excluding any proceeds from units sold pursuant to the underwriter’s over-allotment option. The underwriter paid the Company an aggregate amount of $2,000,000 at the closing of the Initial Public Offering as reimbursement to the Company for certain of its expenses and fees incurred in connection with the Initial Public Offering. Additionally, the underwriter was entitled to a deferred underwriting discount of 3.50% of the gross proceeds of the Initial Public Offering held in the Trust Account, other than the gross proceeds from the units sold pursuant to the underwriter’s option to purchase additional units, and 5.5% of the gross proceeds from the additional units sold pursuant to such option, or $7,568,750 in the aggregate, payable upon the completion of the Company’s initial Business Combination subject to the terms of the underwriting agreement. The deferred underwriting discount will be payable to the underwriter upon the closing of the initial Business Combination in two portions: (i) $0.10 per unit sold in this offering shall be paid to the underwriter in cash and (ii) up to $0.25 per unit sold in this offering (other than the units sold pursuant to the underwriter’s option to purchase additional units, which will be up to $0.45 per unit sold pursuant to such option), shall be paid to the underwriter in cash based on the funds remaining in the Trust Account after giving effect to public shares that are redeemed in connection with an initial Business Combination.

Deferred Legal Fees

As of May 16, 2025, the Company had a total deferred legal fee of $751,429, all of which was related to the Initial Public Offering to be paid to the Company’s legal advisors upon consummation of the Business Combination. As the settlement or liquidation of amounts of deferred legal fees are not reasonably expected to require the use of current assets or require the creation of current liabilities, the amount is classified as a non-current liability in the accompanying balance sheet as of May 16, 2025.

Risks and Uncertainties

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing Russia-Ukraine conflict and the Israel-Hamas conflict. In response to the ongoing Russia-Ukraine conflict, the North Atlantic Treaty Organization (“NATO”) deployed additional military forces to eastern Europe, and the United States, the United Kingdom, the European Union and other countries have announced various sanctions and restrictive actions against Russia, Belarus and related individuals and entities, including the removal of certain financial institutions from the Society for Worldwide Interbank Financial Telecommunication payment system. Certain countries, including the United States, have also provided and may continue to provide military aid or other assistance to Ukraine and to Israel, increasing geopolitical tensions among a number of nations. The invasion of Ukraine by Russia and the Israel-Hamas conflict and the resulting measures that have been taken, and could be taken in the future, by NATO, the United States, the United Kingdom, the European Union, Israel and its neighboring states and other countries have created global security concerns that could have a lasting impact on regional and global economies. Although the length and impact of the ongoing conflicts are highly unpredictable, they could lead to market disruptions, including significant volatility in commodity prices, credit and capital markets, as well as supply chain interruptions and increased cyber-attacks against U.S. companies. Additionally, any resulting sanctions could adversely affect the global economy and financial markets and lead to instability and lack of liquidity in capital markets.

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the Russian invasion of Ukraine, the Israel-Hamas conflict and subsequent sanctions or related actions, could adversely affect the Company’s search for an initial Business Combination and any target business with which the Company may ultimately consummate an initial Business Combination.

Note 6 — Shareholders’ Deficit

Preference Shares — The Company is authorized to issue a total of 1,000,000 preference shares at par value of $0.0001 each. As of May 16, 2025, there were no preference shares issued or outstanding.

Class A Ordinary Shares — The Company is authorized to issue a total of 100,000,000 Class A ordinary shares at par value of $0.0001 each. As of May 16, 2025, there were 362,500 Class A ordinary shares issued and outstanding, excluding 20,125,000 shares subject to possible redemption.

Class B Ordinary Shares — The Company is authorized to issue a total of 10,000,000 Class B ordinary shares at par value of $0.0001 each. As of May 16, 2025, there were 6,708,333 Class B ordinary shares issued and outstanding.

Ordinary shareholders of record are entitled to one vote for each share held on all matters to be voted on by shareholders. Holders of Class A ordinary shares and holders of Class B ordinary shares will vote together as a single class on all matters submitted to a vote of the Company’s shareholder except as required by law. Unless specified in the amended and restated memorandum and articles of association, or as required by applicable provisions of the Companies Act or applicable share exchange rules, the affirmative vote of a majority of the Company’s ordinary shares that are voted is required to approve any such matter voted on by the shareholders. Approval of certain actions will require a special resolution under the amended and restated memorandum and articles of association and Cayman Islands law, which is a resolution passed by a majority of at least two-thirds of the shareholders as, being entitled to do so, vote in person or by proxy at a general meeting of the company and includes a unanimous written resolution, and pursuant to the amended and restated memorandum and articles of association such actions include amending the amended and restated memorandum and articles of association and approving a statutory merger or consolidation with another company. The board of directors is divided into three classes, each of which will generally serve for a term of three years with only one class of directors being appointed in each year. There is no cumulative voting with respect to the appointment of directors, with the result that the holders of more than 50% of the shares voted for the appointment of directors can elect all of the directors. However, only holders of Class B ordinary shares will have the right to appoint directors in any election held prior to the completion of the initial Business Combination, meaning that holders of Class A ordinary shares will not have the right to appoint any directors until after the completion of the initial Business Combination.

In addition, only the Class B ordinary shares will be entitled to vote to continue the Company in a jurisdiction outside of the Cayman Islands. The provisions of the amended and restated memorandum and articles of association governing the continuation in a jurisdiction outside the Cayman Islands prior to the initial Business Combination may only be amended by a special resolution, which is a resolution passed by at least two-thirds of the shareholders as, being entitled to do so, vote in person or by proxy at a general meeting of the Company and includes a unanimous written resolution, which shall include the affirmative vote of a simple majority of the Class B ordinary shares.

F-11

The Class B ordinary shares will automatically convert into Class A ordinary shares at the time of the initial Business Combination on a one-for-one basis (subject to adjustment for subdivisions, share dividends, reorganizations, recapitalizations and the like), and subject to further adjustment as provided herein. In the case that additional Class A ordinary shares, or equity-linked securities, are issued or deemed issued in excess of the amounts offered in this prospectus and related to the closing of the Business Combination, including pursuant to a specified future issuance, the ratio at which Class B ordinary shares shall convert into Class A ordinary shares will be adjusted (unless the initial shareholders agree to waive such adjustment with respect to any such issuance or deemed issuance, including a specified future issuance) so that the number of Class A ordinary shares issuable upon conversion of all Class B ordinary shares will equal, in the aggregate, on an as-converted basis, 25% of the sum of the total number of all ordinary shares outstanding upon completion of this offering plus all Class A ordinary shares and equity-linked securities issued or deemed issued in connection with the Business Combination (after giving effect to any redemptions of Class A ordinary shares by public shareholders) (excluding any shares or equity-linked securities issued, or to be issued, to any seller in the initial Business Combination and any private units issued to the Sponsor, officers or directors upon conversion of working capital loans). The Sponsor may also elect to convert their Class B ordinary shares into an equal number of Class A ordinary shares, subject to adjustment as provided above, at any time. In no event will the Class B ordinary shares convert into shares of Class A ordinary shares at a rate of less than one to one.

Rights — Except in cases where the Company is not the surviving company in a Business Combination, each holder of a right will automatically receive one-tenth (1/10) of one ordinary share upon consummation of the initial Business Combination. The Company will not issue fractional shares in connection with an exchange of rights. Fractional shares will either be rounded down to the nearest whole share or otherwise addressed in accordance with the applicable provisions of Cayman law. In the event the Company is not the surviving company upon completion of the initial Business Combination, each holder of a right will be required to affirmatively convert his, her or its rights in order to receive the one-tenth (1/10) of one ordinary share underlying each right upon consummation of the Business Combination. If the Company is unable to complete the initial Business Combination within the Combination Period and the Company will redeem the public shares for the funds held in the Trust Account, holders of rights will not receive any of such funds for their rights and the rights will expire worthless.

Note 7 — 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). 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.

The fair value of the Public Rights issued in the Initial Public Offering is $4,025,000, or $0.20 per Public Right. The Public Rights issued in the Initial Public Offering have been classified within shareholders’ deficit and will not require remeasurement after issuance. The following table presents the quantitative information regarding market assumptions used in the valuation of the Public Rights issued in the Initial Public Offering:


	May 16, 2025
Traded unit price	$	10.05
Expected term to De-SPAC (Years)		1.8
Probability of De-SPAC and instrument-specific market adjustment		20.0	%
Risk-free rate (continuous)		3.98	%

Note 8 — Segment Information

ASC Topic 280, “Segment Reporting,” establishes standards for companies to report in their financial statement information about operating segments, products, services, geographic areas, and major customers. Operating segments are defined as components of an enterprise for which separate financial information is available that is regularly evaluated by the Company’s 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 operating results for the Company as a whole to make decisions about allocating resources and assessing financial performance. Accordingly, management has determined that the Company only has one reportable segment.

The CODM assesses performance for the single segment and decides how to allocate resources. The measure of segment assets is reported on the balance sheet as total assets. When evaluating the Company’s performance and making key decisions regarding resource allocation the CODM reviews several key metrics, which include the following:


	May 16, 2025
Cash held in Trust Account	$	2,125,000

Note 9 — Subsequent Events

The Company evaluated subsequent events and transactions that occurred after the balance sheet date through the date that the financial statement was issued. Based upon this review, the Company did not identify any subsequent events that would have required adjustment or disclosure in the financial statement.
