THIS PROMISSORY NOTE (“NOTE”) HAS NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE “SECURITIES ACT”). THIS NOTE HAS BEEN ACQUIRED FOR INVESTMENT ONLY AND MAY NOT BE SOLD, TRANSFERRED OR ASSIGNED IN THE ABSENCE OF REGISTRATION OF THE RESALE THEREOF UNDER THE SECURITIES ACT OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY IN FORM, SCOPE AND SUBSTANCE TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED.

PROMISSORY NOTE

Kensington Capital Acquisition Corp. V, a Cayman Islands exempted company and blank check company (the “Maker”), promises to pay to the order of Kensington Capital Sponsor V LLC or its registered assigns or successors in interest (the “Payee”), or order, the principal sum of up to Nine Hundred Fifty Thousand Two Hundred Fifty Dollars ($950,250) in lawful money of the United States of America, on the terms and conditions described below. All payments on this Note shall be made by check or wire transfer of immediately available funds or as otherwise determined by the Maker to such account as the Payee may from time to time designate by written notice in accordance with the provisions of this Note.

1. Principal. The principal balance of this Note shall be payable by the Maker on the earlier of (i)consummation of the Maker’s initial business combination (such date, the “Maturity Date”) unless converted into working capital warrants, as described in the registration statement that the Maker filed in connection with the initial public offering of its securities. The principal balance may be prepaid at any time. Under no circumstances shall any individual, including but not limited to any officer, director, employee or shareholder of the Maker, be obligated personally for any obligations or liabilities of the Maker hereunder.

2. Interest. No interest shall accrue on the unpaid principal balance of this Note.

3. Drawdown Requests. The Maker and the Payee agree that Maker may request up to Nine Hundred Fifty Thousand Two Hundred Fifty Dollars ($950,250) for working capital loans, as described in the registration statement that the Maker filed in connection with the initial public offering of its securities. The principal of this Note may be drawn down from time to time prior to the Maturity Date (each, a “Drawdown Request”). Each Drawdown Request must state the amount to be drawn down, and must not be an amount less than Ten Thousand Dollars ($10,000) unless agreed upon by the Maker and the Payee. The Payee shall fund each Drawdown Request no later than five (5) business days after receipt of a Drawdown Request; provided, however, that the maximum amount of drawdowns collectively under this Note is Nine Hundred Fifty Thousand Two Hundred Fifty Dollars ($950,250). Once an amount is drawn down under this Note, it shall not be available for future Drawdown Requests even if prepaid. No fees, payments or other amounts shall be due to Payee in connection with, or as a result of, any Drawdown Request by Maker. Notwithstanding the foregoing, all payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorneys’ fees, and then to the reduction of the unpaid principal balance of this Note.

4. Application of Payments. All payments shall be applied first to payment in full of any costs incurred in the collection of any sum due under this Note, including (without limitation) reasonable attorney’s fees, then to the payment in full of any late charges and finally to the reduction of the unpaid principal balance of this Note.

5. Conversion.

(a) Optional Conversion. At the option of the Payee, at any time on or prior to the Maturity Date, any amounts outstanding under this Note (or any portion thereof), may be converted into whole warrants to purchase shares of Class A ordinary shares of the Maker at a conversion price (the “Conversion Price”) per warrant (“Warrants”) equal to $0.75. If the Payee elects such conversion, the terms of such Warrants issued in connection with such conversion shall be identical to the warrants issued to the Payee in a private placement (the “Private Placement Warrants”) in connection with the Maker’s initial public offering, including that each Warrant will

entitle the holder thereof to purchase one share of Class A ordinary shares at a price of $11.50 per share, subject to adjustment. Before this Note may be converted under this Section 5(a), the Payee shall surrender this Note, duly endorsed, at the office of the Maker and shall state therein the amount of the unpaid principal of this Note to be converted and the name or names in which the certificates for Warrants are to be issued (or the book-entries to be made to reflect ownership of such Warrants with the Maker’s transfer agent). The conversion shall be deemed to have been made immediately prior to the close of business on the date of the surrender of this Note and the person or persons entitled to receive the Warrants upon such conversion shall be treated for all purposes as the record holder or holders of such Warrants as of such date. Each such newly-issued Warrant shall include a restricted legend that contemplates the same restrictions as the Private Placement Warrants.

(b) Remaining Principal. All accrued and unpaid principal of this Note that is not then converted into Warrants, shall continue to remain outstanding and to be subject to the conditions of this Note.

(c) Fractional Warrants; Effect of Conversion. No fractional Warrants shall be issued upon conversion of this Note. In lieu of any fractional Warrants to the Payee upon conversion of this Note, the Maker shall pay to the Payee an amount equal to the product obtained by multiplying the Conversion Price by the fraction of a Warrant not issued pursuant to the previous sentence. Upon conversion of this Note in full and the payment of any amounts specified in this Section 5(c), this Note shall be cancelled and void without further action of the Maker or the Payee, and the Maker shall be forever released from all its obligations and liabilities under this Note.

6. Events of Default. The following shall constitute an event of default (“Event of Default”):

(a) Failure to Make Required Payments. Failure by Maker to pay the principal amount due pursuant to this Note within five (5) business days of the Maturity Date.

(b) Voluntary Bankruptcy, Etc. The commencement by Maker of a voluntary case under any applicable bankruptcy, insolvency, reorganization, rehabilitation or other similar law, or the consent by it to the appointment of or taking possession by a receiver, liquidator, assignee, trustee, custodian, sequestrator (or other similar official) of Maker or for any substantial part of its property, or the making by it of any assignment for the benefit of creditors, or the failure of Maker generally to pay its debts as such debts become due, or the taking of corporate action by Maker in furtherance of any of the foregoing.

(c) Involuntary Bankruptcy, Etc. The entry of a decree or order for relief by a court having jurisdiction in the premises in respect of Maker in an involuntary case under any applicable bankruptcy, insolvency or other similar law, or appointing a receiver, liquidator, assignee, custodian, trustee, sequestrator (or similar official) of Maker or for any substantial part of its property, or ordering the winding-up or liquidation of its affairs, and the continuance of any such decree or order unstayed and in effect for a period of 60 consecutive days.

7. Remedies.

(a) Upon the occurrence of an Event of Default specified in Section 6(a) hereof, Payee may, by written notice to Maker, declare this Note to be due immediately and payable, whereupon the unpaid principal amount of this Note, and all other amounts payable hereunder, shall become immediately due and payable without presentment, demand, protest or other notice of any kind, all of which are hereby expressly waived, anything contained herein or in the documents evidencing the same to the contrary notwithstanding.

(b) Upon the occurrence of an Event of Default specified in Sections 6(b) and 6(c), the unpaid principal balance of this Note, and all other sums payable with regard to this Note, shall automatically and immediately become due and payable, in all cases without any action on the part of Payee.

8. Waivers. Maker and all endorsers and guarantors of, and sureties for, this Note waive presentment for payment, demand, notice of dishonor, protest, and notice of protest with regard to the Note, all errors, defects and imperfections in any proceedings instituted by Payee under the terms of this Note, and all benefits that might accrue to Maker by virtue of any present or future laws exempting any property, real or personal, or any part of the proceeds arising from any sale of any such property, from attachment, levy or sale under execution, or providing for any stay of execution, exemption from civil process, or extension of time for payment; and Maker agrees that any real estate that may be levied upon pursuant to a judgment obtained by virtue hereof or any writ of execution issued hereon, may be sold upon any such writ in whole or in part in any order desired by Payee.

9. Unconditional Liability. Maker hereby waives all notices in connection with the delivery, acceptance, performance, default, or enforcement of the payment of this Note, and agrees that its liability shall be unconditional, without regard to the liability of any other party, and shall not be affected in any manner by any indulgence, extension of time, renewal, waiver or modification granted or consented to by Payee, and consents to any and all extensions of time, renewals, waivers, or modifications that may be granted by Payee with respect to the payment or other provisions of this Note, and agrees that additional makers, endorsers, guarantors, or sureties may become parties hereto without notice to Maker or affecting Maker’s liability hereunder.

11. Construction. THIS NOTE SHALL BE CONSTRUED AND ENFORCED IN ACCORDANCE WITH THE LAWS OF DELAWARE, WITHOUT REGARD TO CONFLICT OF LAW PROVISIONS THEREOF.

12. Severability. Any provision contained in this Note which is prohibited or unenforceable in any jurisdiction shall, as to such jurisdiction, be ineffective to the extent of such prohibition or unenforceability without invalidating the remaining provisions hereof, and any such prohibition or unenforceability in any jurisdiction shall not invalidate or render unenforceable such provision in any other jurisdiction.

13. Trust Waiver. Notwithstanding anything herein to the contrary, the Payee hereby waives any and all right, title, interest or claim of any kind (“Claim”) in or to any distribution of or from the trust account to be established in which the proceeds of the initial public offering (the “IPO”) to be conducted by the Maker (including the deferred underwriters discounts and commissions) and the proceeds of the sale of the warrants to be issued in a private placement to occur prior to the closing of the IPO are to be deposited, as described in greater detail in the registration statement and prospectus to be filed with the Securities and Exchange Commission in connection with the IPO, and hereby agrees not to seek recourse, reimbursement, payment or satisfaction for any Claim against the trust account for any reason whatsoever.

14. Amendment; Waiver. Any amendment hereto or waiver of any provision hereof may be made with, and only with, the written consent of the Maker and the Payee.

15. Assignment. No assignment or transfer of this Note or any rights or obligations hereunder may be made by any party hereto (by operation of law or otherwise) without the prior written consent of the other party hereto and any attempted assignment without the required consent shall be void.
