Organization and Plan of Business Operations	NOTE 1 — ORGANIZATION AND PLAN OF BUSINESS OPERATIONS Kensington Capital Acquisition Corp. VI (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on December 4, 2025. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of completing a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of December 31, 2025, the Company had not commenced any operations. All activity for the period from December 4, 2025 (inception) through December 31, 2025 relates to the Company’s formation and the proposed initial public offering (“Proposed Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Proposed Public Offering. The Company has selected December 31 as its fiscal year end. The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a Proposed Public Offering of 20,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”) at $10.00 per Unit (or 23,000,000 Units if the underwriters’ over-allotment option is exercised in full), which is discussed in Note 3, and the sale of an aggregate of 10,733,333 Private Placement Warrants (“Private Placement Warrants”) at a price of $0.44 per private placement warrant (or 11,533,333 Private Placement Warrants if the underwriters’ over-allotment option is exercised in full at a price of $0.43 per Private Placement Warrant) or $4,700,000 in the aggregate (or $5,000,000 if the underwriters’ overallotment option is exercised in full) in a private placement that will close simultaneously with the closing of the Proposed Public Offering. The underwriters have committed to use a portion of their underwriting discount and commission to purchase an aggregate of 2,666,667 Private Placement Warrants (or 3,066,667 Private Placement Warrants if the underwriters’ over-allotment option is exercised in full) at a price of $0.75 per warrant, or $2,000,000 in the aggregate (or $2,300,000 in the aggregate if the underwriters’ overallotment option is exercised in full), in a private placement that will close simultaneously with the closing of the Proposed Public Offering. The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the sale of the Private Placement Securities, although substantially all of the net proceeds are intended to be applied generally toward completing a Business Combination. The Company must complete its initial Business Combination with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding the Permitted Withdrawals and any deferred underwriting commissions held in the Trust Account) at the time of the agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Public Offering, management has agreed that $10.00 per Unit sold in the Proposed Public Offering, including proceeds of the sale of the Private Placement Securities, will be held in a trust account (“Trust Account”) and invested or held only in (i) U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries, (ii) uninvested cash, or (iii) an interest bearing bank demand deposit account or other accounts at a bank, as determined by the Company, until the earlier of (i) the completion of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. No later than 24 months after the closing of the Proposed Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or such later time as provided for in any amendment to the Company’s Amended and Restated Memorandum and Articles of Association (an “Extension Period”), subject to applicable law, the amounts held in the Trust Account will be held as cash or cash items, including in demand deposit accounts. The Company will provide its shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount held in the Trust Account (initially $10.00 per share), calculated as of two business days prior to the completion of a Business Combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations or funds for working capital requirements (net of taxes), (“Permitted Withdrawals”). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s public warrants. The Class A ordinary shares will be recorded at redemption value and classified as temporary equity upon the completion of the Proposed Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” If the Company seeks shareholder approval in connection with a Business Combination, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who vote at a general meeting of the Company. If a shareholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased in or after the Proposed Public Offering in favor of approving a Business Combination and to waive its redemption rights with respect to any such shares in connection with a shareholder vote to approve a Business Combination. Additionally, each public shareholder may elect to redeem its Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination. Notwithstanding the foregoing, if the Company seeks shareholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Memorandum and Articles of Association 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 Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent. The Initial Shareholder has agreed to (i) waive its redemption rights with respect to its private placement shares in connection with the completion of the initial business combination, (ii) waive its redemption rights with respect to its private placement shares in connection with a shareholder vote to approve an amendment to the amended and restated memorandum and articles of association (A) to modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the public shares if the Company fails to complete the initial Business Combination within 24 months from the closing of the Proposed Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period, subject to applicable law or (B) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity and (iii) waive its rights to liquidating distributions from the Trust Account with respect to its private placement shares if the Company fails to complete the initial Business Combination within the prescribed timeframe. In addition, the Sponsor has agreed to vote any private placement shares held by it in favor of the initial Business Combination. The Company will have until 24 months from the closing of the Proposed Public Offering to complete a Business Combination or until such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period (the “Combination Period”). If the Company has not completed a Business Combination within the Combination Period, and the board of directors has made a determination, and provided notice to the shareholders, that the Company is unable to, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, including interest earned on the funds held in the Trust Account (which interest shall be net of permitted withdrawals and up to $100,000 of interest to pay dissolution expenses) and not previously released to the Company to pay its taxes and permitted withdrawals, 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 liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Initial Shareholder has agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholder acquires Public Shares in or after the Proposed Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the initial amount held in the Trust Account ($10.00). The Sponsor has agreed that it will be liable to the Company, if and to the extent any claims by a third party for services rendered or products sold to the Company, or by a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.00 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of trust assets, in each case net of the amount of interest which may be withdrawn for permitted withdrawals. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the Company’s indemnity of the underwriters of the Proposed Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent auditors), 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. Going Concern Consideration As of December 31, 2025, the Company had $121,831 cash and a working capital deficit of $63,657. Further, the Company expects to continue to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The Company plans to address this uncertainty through a Proposed Public Offering as discussed in Note 3 and the sale of Private Placement Warrants as discussed in Note 4. There is no assurance that the Company’s plans to raise capital or to consummate a Business Combination will be successful or successful within the target business acquisition period. The financial statements do not include any adjustments that might result from the outcome of this uncertainty. Risks and Uncertainties The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing global conflicts. 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 cyberattacks 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 1 — ORGANIZATION AND PLAN OF BUSINESS OPERATIONS Kensington Capital Acquisition Corp. VI (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on December 4, 2025. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Business Combination”). The Company is not limited to a particular industry or geographic region for purposes of completing a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies. As of June 30, 2026, the Company had not commenced any operations. All activity for the period from December 4, 2025 (inception) through June 30, 2026 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a 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. The Company’s Sponsor is Kensington Capital Sponsor VI LLC (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on March 3, 2026. On March 5, 2026, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units, the “Public Shares”) at $10.00 per Unit, which includes the full exercise of the Underwriters’ (as defined in Note 4) over-allotment option of 3,000,000 Units, generating gross proceeds of $230,000,000, which is discussed in Note 3. Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 11,533,333 private placement warrants (“Private Placement Warrants”) to the Sponsor at a price of $0.43 per Private Placement Warrant, or $5,000,000 in the aggregate. The Underwriters purchased an aggregate of 3,066,667 Private Placement Warrants at a price of $0.75 per Private Placement Warrant, or $2,300,000 in the aggregate. Transaction costs amounted to $14,759,229, consisting of $4,600,000 of cash underwriting fee, $9,200,000 of deferred underwriting fee, and $959,229 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 the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward completing a Business Combination. The Company must complete its initial Business Combination with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding the Permitted Withdrawals (as defined below) and any deferred underwriting commissions held in the Trust Account) at the time of the agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Initial Public Offering on March 5, 2026, an amount of $230,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units, and a portion of the proceeds of the sale of the Private Placement Warrants, are held in a trust account (the “Trust Account”) and will be invested or held only in (i) U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries, (ii) uninvested cash, or (iii) an interest bearing bank demand deposit account or other accounts at a bank, as determined by the Company, until the earlier of (i) the completion of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. No later than 24 months after the closing of the Initial Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or such later time as provided for in any amendment to the Company’s Amended and Restated Memorandum and Articles of Association (an “Extension Period”), subject to applicable law, the amounts held in the Trust Account will be held as cash or cash items, including in demand deposit accounts. The Company will provide its shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer.

There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s Public Warrants (as defined in Note 3). The Class A ordinary shares are recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.” If the Company seeks shareholder approval in connection with a Business Combination, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who vote at a general meeting of the Company.

If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased in or after the Initial Public Offering in favor of approving a Business Combination and to waive its redemption rights with respect to any such shares in connection with a shareholder vote to approve a Business Combination. Additionally, each public shareholder may elect to redeem its Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination.

If the Company has not completed a Business Combination within the Combination Period, and the board of directors has made a determination, and provided notice to the shareholders, that the Company is unable to, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, including interest earned on the funds held in the Trust Account (which interest shall be net of Permitted Withdrawals and up to $100,000 of interest to pay dissolution expenses) and not previously released to the Company to pay its taxes and Permitted Withdrawals, 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 liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law. The Initial Shareholder has agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholder acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The Underwriters have agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the initial amount held in the Trust Account ($10.00). The Sponsor has agreed that it will be liable to the Company, if and to the extent any claims by a third party for services rendered or products sold to the Company, or by a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.00 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of trust assets, in each case net of the amount of interest which may be withdrawn for Permitted Withdrawals. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the Company’s indemnity of the Underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent auditors), 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.

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 military escalations between the United States and Iran, 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.

Organization and Plan of Business Operations

NOTE 1 — ORGANIZATION AND PLAN OF BUSINESS OPERATIONS

Kensington Capital Acquisition Corp. VI (the “Company”) is a blank check company incorporated as a Cayman Islands exempted corporation on December 4, 2025. The Company was incorporated for the purpose of effecting a merger, share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (“Business Combination”).

The Company is not limited to a particular industry or geographic region for purposes of completing a Business Combination. The Company is an early stage and emerging growth company and, as such, the Company is subject to all of the risks associated with early stage and emerging growth companies.

As of December 31, 2025, the Company had not commenced any operations. All activity for the period from December 4, 2025 (inception) through December 31, 2025 relates to the Company’s formation and the proposed initial public offering (“Proposed Public Offering”), which is described below. The Company will not generate any operating revenues until after the completion of a Business Combination, at the earliest. The Company will generate non-operating income in the form of interest income from the proceeds derived from the Proposed Public Offering. The Company has selected December 31 as its fiscal year end.

The Company’s ability to commence operations is contingent upon obtaining adequate financial resources through a Proposed Public Offering of 20,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units being offered, the “Public Shares”) at $10.00 per Unit (or 23,000,000 Units if the underwriters’ over-allotment option is exercised in full), which is discussed in Note 3, and the sale of an aggregate of 10,733,333 Private Placement Warrants (“Private Placement Warrants”) at a price of $0.44 per private placement warrant (or 11,533,333 Private Placement Warrants if the underwriters’ over-allotment option is exercised in full at a price of $0.43 per Private Placement Warrant) or $4,700,000 in the aggregate (or $5,000,000 if the underwriters’ overallotment option is exercised in full) in a private placement that will close simultaneously with the closing of the Proposed Public Offering. The underwriters have committed to use a portion of their underwriting discount and commission to purchase an aggregate of 2,666,667 Private Placement Warrants (or 3,066,667 Private Placement Warrants if the underwriters’ over-allotment option is exercised in full) at a price of $0.75 per warrant, or $2,000,000 in the aggregate (or $2,300,000 in the aggregate if the underwriters’ overallotment option is exercised in full), in a private placement that will close simultaneously with the closing of the Proposed Public Offering.

The Company’s management has broad discretion with respect to the specific application of the net proceeds of the Proposed Public Offering and the sale of the Private Placement Securities, although substantially all of the net proceeds are intended to be applied generally toward completing a Business Combination. The Company must complete its initial Business Combination with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding the Permitted Withdrawals and any deferred underwriting commissions held in the Trust Account) at the time of the agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Proposed Public Offering, management has agreed that $10.00 per Unit sold in the Proposed Public Offering, including proceeds of the sale of the Private Placement Securities, will be held in a trust account (“Trust Account”) and invested or held only in (i) U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries, (ii) uninvested cash, or (iii) an interest bearing bank demand deposit account or other accounts at a bank, as determined by the Company, until the earlier of (i) the completion of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. No later than 24 months after the closing of the Proposed Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or such later time as provided for in any amendment to the Company’s Amended and Restated Memorandum and Articles of Association (an “Extension Period”), subject to applicable law, the amounts held in the Trust Account will be held as cash or cash items, including in demand deposit accounts.

The Company will provide its shareholders with the opportunity to redeem all or a portion of their Public Shares upon the completion of a Business Combination either (i) in connection with a general meeting called to approve the Business Combination or (ii) by means of a tender offer. The decision as to whether the Company will seek shareholder approval of a Business Combination or conduct a tender offer will be made by the Company. The shareholders will be entitled to redeem their shares for a pro rata portion of the amount held in the Trust Account (initially $10.00 per share), calculated as of two business days prior to the completion of a Business Combination, including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations or funds for working capital requirements (net of taxes), (“Permitted Withdrawals”). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s public warrants. The Class A ordinary shares will be

recorded at redemption value and classified as temporary equity upon the completion of the Proposed Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

If the Company seeks shareholder approval in connection with a Business Combination, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who vote at a general meeting of the Company. If a shareholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased in or after the Proposed Public Offering in favor of approving a Business Combination and to waive its redemption rights with respect to any such shares in connection with a shareholder vote to approve a Business Combination. Additionally, each public shareholder may elect to redeem its Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination.

Notwithstanding the foregoing, if the Company seeks shareholder approval of a Business Combination and it does not conduct redemptions pursuant to the tender offer rules, the Company’s Amended and Restated Memorandum and Articles of Association 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 Securities Exchange Act of 1934, as amended (the “Exchange Act”)), will be restricted from redeeming its shares with respect to more than an aggregate of 15% of the Public Shares without the Company’s prior written consent.

The Initial Shareholder has agreed to (i) waive its redemption rights with respect to its private placement shares in connection with the completion of the initial business combination, (ii) waive its redemption rights with respect to its private placement shares in connection with a shareholder vote to approve an amendment to the amended and restated memorandum and articles of association (A) to modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the public shares if the Company fails to complete the initial Business Combination within 24 months from the closing of the Proposed Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period, subject to applicable law or (B) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity and (iii) waive its rights to liquidating distributions from the Trust Account with respect to its private placement shares if the Company fails to complete the initial Business Combination within the prescribed timeframe. In addition, the Sponsor has agreed to vote any private placement shares held by it in favor of the initial Business Combination.

The Company will have until 24 months from the closing of the Proposed Public Offering to complete a Business Combination or until such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period (the “Combination Period”). If the Company has not completed a Business Combination within the Combination Period, and the board of directors has made a determination, and provided notice to the shareholders, that the Company is unable to, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, including interest earned on the funds held in the Trust Account (which interest shall be net of permitted withdrawals and up to $100,000 of interest to pay dissolution expenses) and not previously released to the Company to pay its taxes and permitted withdrawals, 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 liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Initial Shareholder has agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholder acquires Public Shares in or after the Proposed Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The underwriters have agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the initial amount held in the Trust Account ($10.00).

The Sponsor has agreed that it will be liable to the Company, if and to the extent any claims by a third party for services rendered or products sold to the Company, or by a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.00 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of trust assets, in each case net of the amount of interest which may be withdrawn for permitted withdrawals. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the Company’s indemnity of the underwriters of the Proposed Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent auditors), 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.

Going Concern Consideration

As of December 31, 2025, the Company had $121,831 cash and a working capital deficit of $63,657. Further, the Company expects to continue to incur significant costs in pursuit of its financing and acquisition plans. These conditions raise substantial doubt about the Company’s ability to continue as a going concern. The Company plans to address this uncertainty through a Proposed Public Offering as discussed in Note 3 and the sale of Private Placement Warrants as discussed in Note 4. There is no assurance that the Company’s plans to raise capital or to consummate a Business Combination will be successful or successful within the target business acquisition period. The financial statements do not include any adjustments that might result from the outcome of this uncertainty.

Risks and Uncertainties

The United States and global markets are experiencing volatility and disruption following the geopolitical instability resulting from the ongoing global conflicts. 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 cyberattacks 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 1 — ORGANIZATION AND PLAN OF BUSINESS OPERATIONS

As of June 30, 2026, the Company had not commenced any operations. All activity for the period from December 4, 2025 (inception) through June 30, 2026 relates to the Company’s formation, the initial public offering (“Initial Public Offering”), which is described below and subsequent to the Initial Public Offering, identifying a target company for a Business Combination. The Company will not generate any operating revenues until after the completion of a 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.

The Company’s Sponsor is Kensington Capital Sponsor VI LLC (the “Sponsor”). The registration statement for the Company’s Initial Public Offering was declared effective on March 3, 2026. On March 5, 2026, the Company consummated the Initial Public Offering of 23,000,000 units (the “Units” and, with respect to the Class A ordinary shares included in the Units, the “Public Shares”) at $10.00 per Unit, which includes the full exercise of the Underwriters’ (as defined in Note 4) over-allotment option of 3,000,000 Units, generating gross proceeds of $230,000,000, which is discussed in Note 3.

Simultaneously with the closing of the Initial Public Offering, the Company consummated the sale of an aggregate of 11,533,333 private placement warrants (“Private Placement Warrants”) to the Sponsor at a price of $0.43 per Private Placement Warrant, or $5,000,000 in the aggregate. The Underwriters purchased an aggregate of 3,066,667 Private Placement Warrants at a price of $0.75 per Private Placement Warrant, or $2,300,000 in the aggregate.

Transaction costs amounted to $14,759,229, consisting of $4,600,000 of cash underwriting fee, $9,200,000 of deferred underwriting fee, and $959,229 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 the Private Placement Warrants, although substantially all of the net proceeds are intended to be applied generally toward completing a Business Combination. The Company must complete its initial Business Combination with one or more target businesses that together have a fair market value equal to at least 80% of the net assets held in the Trust Account (as defined below) (excluding the Permitted Withdrawals (as defined below) and any deferred underwriting commissions held in the Trust Account) at the time of the agreement to enter into a Business Combination. The Company will only complete a Business Combination if the post-Business Combination company owns or acquires 50% or more of the issued and outstanding voting securities of the target or otherwise acquires a controlling interest in the target business sufficient for it not to be required to register as an investment company under the Investment Company Act of 1940, as amended (the “Investment Company Act”). There is no assurance that the Company will be able to successfully effect a Business Combination. Upon the closing of the Initial Public Offering on March 5, 2026, an amount of $230,000,000 ($10.00 per Unit) from the net proceeds of the sale of the Units, and a portion of the proceeds of the sale of the Private Placement Warrants, are held in a trust account (the “Trust Account”) and will be invested or held only in (i) U.S. government treasury bills with a maturity of 185 days or less or in money market funds investing solely in U.S. Treasuries, (ii) uninvested cash, or (iii) an interest bearing bank demand deposit account or other accounts at a bank, as determined by the Company, until the earlier of (i) the completion of a Business Combination or (ii) the distribution of the funds in the Trust Account to the Company’s shareholders, as described below. No later than 24 months after the closing of the Initial Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or such later time as provided for in any amendment to the Company’s Amended and Restated Memorandum and Articles of Association (an “Extension Period”), subject to applicable law, the amounts held in the Trust Account will be held as cash or cash items, including in demand deposit accounts.

including any pro rata interest earned on the funds held in the Trust Account and not previously released to the Company to pay its tax obligations or funds for working capital requirements (net of taxes), (“Permitted Withdrawals”). There will be no redemption rights upon the completion of a Business Combination with respect to the Company’s Public Warrants (as defined in Note 3). The Class A ordinary shares are recorded at redemption value and classified as temporary equity upon the completion of the Initial Public Offering, in accordance with Accounting Standards Codification (“ASC”) Topic 480, “Distinguishing Liabilities from Equity.”

If the Company seeks shareholder approval in connection with a Business Combination, it receives an ordinary resolution under Cayman Islands law approving a Business Combination, which requires the affirmative vote of a majority of the shareholders who vote at a general meeting of the Company. If a shareholder vote is not required under applicable law or stock exchange listing requirements and the Company does not decide to hold a shareholder vote for business or other reasons, the Company will, pursuant to its Amended and Restated Memorandum and Articles of Association, conduct the redemptions pursuant to the tender offer rules of the Securities and Exchange Commission (“SEC”), and file tender offer documents containing substantially the same information as would be included in a proxy statement with the SEC prior to completing a Business Combination. If the Company seeks shareholder approval in connection with a Business Combination, the Sponsor has agreed to vote its Founder Shares (as defined in Note 5) and any Public Shares purchased in or after the Initial Public Offering in favor of approving a Business Combination and to waive its redemption rights with respect to any such shares in connection with a shareholder vote to approve a Business Combination. Additionally, each public shareholder may elect to redeem its Public Shares, without voting, and if they do vote, irrespective of whether they vote for or against a proposed Business Combination.

The Initial Shareholder (as defined in Note 5) has agreed to (i) waive its redemption rights with respect to its private placement shares in connection with the completion of the initial Business Combination, (ii) waive its redemption rights with respect to its private placement shares in connection with a shareholder vote to approve an amendment to the Amended and Restated Memorandum and Articles of Association (A) to modify the substance or timing of the obligation to allow redemption in connection with the initial Business Combination or to redeem 100% of the Public Shares if the Company fails to complete the initial Business Combination within 24 months from the closing of the Initial Public Offering or such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period, subject to applicable law or (B) with respect to any other provision relating to shareholders’ rights or pre-initial business combination activity and (iii) waive its rights to liquidating distributions from the Trust Account with respect to its private placement shares if the Company fails to complete the initial Business Combination within the prescribed timeframe. In addition, the Sponsor has agreed to vote any private placement shares held by it in favor of the initial Business Combination.

The Company has until 24 months from the closing of the Initial Public Offering to complete a Business Combination or until such earlier liquidation date as the Company’s board of directors may approve, or during any Extension Period (the “Combination Period”). If the Company has not completed a Business Combination within the Combination Period, and the board of directors has made a determination, and provided notice to the shareholders, that the Company is unable to, the Company will (i) cease all operations except for the purpose of winding up, (ii) as promptly as reasonably possible but no more than 10 business days thereafter, redeem 100% of the outstanding Public Shares, at a per-share price, payable in cash, including interest earned on the funds held in the Trust Account (which interest shall be net of Permitted Withdrawals and up to $100,000 of interest to pay dissolution expenses) and not previously released to the Company to pay its taxes and Permitted Withdrawals, 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 liquidation distributions, if any), and (iii) as promptly as reasonably possible following such redemption, subject to the approval of the remaining shareholders and the Company’s board of directors, liquidate and dissolve, subject in each case to its obligations under Cayman Islands law to provide for claims of creditors and the requirements of other applicable law.

The Initial Shareholder has agreed to waive their liquidation rights with respect to the Founder Shares if the Company fails to complete a Business Combination within the Combination Period. However, if the Initial Shareholder acquires Public Shares in or after the Initial Public Offering, such Public Shares will be entitled to liquidating distributions from the Trust Account if the Company fails to complete a Business Combination within the Combination Period. The Underwriters have agreed to waive its rights to its deferred underwriting commission (see Note 6) held in the Trust Account in the event the Company does not complete a Business Combination within the Combination Period and, in such event, such amounts will be included with the funds held in the Trust Account that will be

available to fund the redemption of the Public Shares. In the event of such distribution, it is possible that the per share value of the assets remaining available for distribution will be less than the initial amount held in the Trust Account ($10.00).

The Sponsor has agreed that it will be liable to the Company, if and to the extent any claims by a third party for services rendered or products sold to the Company, or by a prospective target business with which the Company has discussed entering into a transaction agreement, reduce the amount of funds in the Trust Account to below (1) $10.00 per Public Share or (2) such lesser amount per Public Share held in the Trust Account as of the date of the liquidation of the Trust Account due to reductions in the value of trust assets, in each case net of the amount of interest which may be withdrawn for Permitted Withdrawals. This liability will not apply with respect to any claims by a third party who executed a waiver of any and all rights to seek access to the Trust Account nor will it apply to any claims under the Company’s indemnity of the Underwriters of the Initial Public Offering against certain liabilities, including liabilities under the Securities Act of 1933, as amended (the “Securities Act”). Moreover, in the event that an executed waiver is deemed to be unenforceable against a third party, the Sponsor will not be responsible to the extent of any liability for such third-party claims. The Company will seek to reduce the possibility that the Sponsor will have to indemnify the Trust Account due to claims of creditors by endeavoring to have all vendors, service providers (other than the Company’s independent auditors), 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.

Risks and Uncertainties

Any of the above mentioned factors, or any other negative impact on the global economy, capital markets or other geopolitical conditions resulting from the military escalations between the United States and Iran, 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.
