This Non-Redemption Agreement and Assignment of Economic Interest (this “Agreement”) is entered as of February 24, 2026 by and among Piermont Valley Acquisition Corp, a Cayman Islands exempted company (“PVAC” or the “Company”), Valleypark Road LLC (the “Insider”), and the undersigned investor (the “Investor”).

RECITALS

WHEREAS, the Insider currently holds PVAC Class A ordinary shares, par value $0.0001 per share (the “Founder Shares”);

WHEREAS, PVAC expects to hold an extraordinary general meeting of shareholders (as adjourned or postponed from time to time, the “Meeting”) for the purpose of approving, among other proposals, an amendment to PVAC’s Amended and Restated Memorandum and Articles of Association (the “Charter”) to, extend the date by which PVAC must consummate an initial business combination (the “Initial Business Combination”) to March 3, 2027 (the “Extension” and together with all other proposals brought at the Meeting, the “Proposals”);

WHEREAS, the Charter provides that a shareholder of PVAC may elect to redeem its Class A ordinary shares, par value $0.0001 per share, initially sold as part of the units in PVAC’s initial public offering (whether they were purchased in PVAC’s initial public offering or thereafter in the open market, the “Public Shares” and together with the Founder Shares, the “Ordinary Shares”) in connection with the proposal to amend the Charter to effectuate the Extension upon the terms and subject to the conditions set forth in the Charter (“Redemption Rights”);

WHEREAS, Investor is willing to not exercise its Redemption Rights in connection with the Extension, or to validly rescind any previously submitted redemption demand, of certain of the Public Shares held by such Investor upon the terms set forth herein; and

WHEREAS, subject to the terms and conditions of this Agreement, the Insider desires to transfer to the Investor, and the Investor desires to acquire from the Insider, that number of Founder Shares set forth opposite such Investor’s name on Exhibit A (the “Assigned Securities”), to be transferred to the Investor simultaneously with PVAC’s completion of its Initial Business Combination, and, prior to the transfer of the Assigned Securities to the Investor, the Insider desires to assign the economic benefits of the Assigned Securities to the Investor.

NOW THEREFORE, in consideration of the mutual covenants and agreements set forth herein and for good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Investor, the Company and the Insider hereby agree as follows:

1. Terms of Transfer.

1.1. Upon the terms and subject to the conditions of this Agreement, if (a) as of 5:30 PM, New York time, on the date of the Meeting, the Investor holds the Investor Shares (as defined below), (b) the Investor does not exercise (or exercised and validly rescinds) its Redemption Rights with respect to all of the Investor Shares in connection with the Meeting, and (c) the Proposals are approved at the Meeting and implemented by the Company, then the Insider hereby agrees to assign to the Investor for no additional consideration the Economic Interest (as defined below) associated with the Assigned Securities set forth on Exhibit A. “Investor Shares” shall mean an amount of the Public Shares equal to the lesser of (i) __200,000___ Public Shares, and (ii) 9.99% of the Public Shares outstanding after the Extension and the events occurring substantially concurrent therewith, including the redemptions of Class A ordinary shares, including those Public Shares subject to non-redemption agreements with other PVAC shareholders similar to this Agreement on or about the date of the Meeting; provided, however, that if the number of Investor Shares is less than __200,000___, the number of Assigned Securities shall be reduced proportionately.

1.2. The Insider and the Investor hereby agree that the assignment of the Economic Interest in the Assigned Securities shall be subject to the conditions that (i) the Initial Business Combination is consummated; (ii) the Investor (or its permitted transferees (as provided by Section 7 of that certain Letter Agreement, dated November 30, 2021, entered into by PVAC in connection with its initial public offering (as amended and as it exists on the date hereof, the “Letter Agreement”)) executes a joinder to the Letter Agreement set forth as Exhibit B to this Agreement and (iii) the Investor furnishes proof satisfactory to the Insider demonstrating its ownership of non-redeemed Investor Shares following the Meeting. The Company and the Insider acknowledge and agree that the voting, Trust Account (as defined in the Letter Agreement) and liquidating distribution restrictions contained in the Letter Agreement (or any other restrictions contained therein) shall only apply to the Assigned Securities and not any Public Shares (including the Investor Shares), and that the obligations with respect to the “Ordinary Shares” referenced in Sections 1 and 2 of the Letter Agreement shall not apply to or restrict Investor, other than with respect to the Assigned Securities (the “Carve-Out”).

Upon the satisfaction of the foregoing conditions, as applicable, the Insider shall transfer the Assigned Securities to the Investor (or its permitted transferees as provided by Section 7 of that certain Letter Agreement) contingent upon and promptly following the closing of the Initial Business Combination free and clear of any liens or other encumbrances, other than restrictions on transfer imposed by the Letter Agreement and the securities laws. The Insider and PVAC covenant and agree to facilitate such transfer to the Investor (or its permitted transferees as provided by Section 7 of that certain Letter Agreement) in accordance with the foregoing.

1.3. Adjustment to Share Amounts. If at any time prior to the consummation of an Initial Business Combination, the number of outstanding Founder Shares is increased or decreased by a consolidation, combination, split or reclassification of the Founder Shares or other similar event, then, as of the effective date of such consolidation, combination, split, reclassification or similar event, all share numbers referenced in this Agreement shall be adjusted in proportion to such increase or decrease in the Founder Shares. The foregoing shall not apply to (i) any increase or decrease in the number of authorized Founder Shares or (ii) a reclassification of the share capital of PVAC, in each case in connection with the closing of the Initial Business Combination.

1.4. Merger or Reorganization, etc. If prior to the transfer of the Assigned Shares to the Investor there shall occur any reorganization, recapitalization, reclassification, consolidation or merger involving PVAC in which its Ordinary Shares are converted into or exchanged for securities, cash or other property, then, following any such reorganization, recapitalization, reclassification, consolidation or merger, in lieu of Ordinary Shares, the Insider shall transfer, with respect to each Founder Share to be transferred hereunder, promptly after and upon the Insider’s receipt thereof, the kind and amount of securities, cash or other property into which such Assigned Securities converted or were exchanged.

1.5. Forfeitures, Transfers, etc. The Investor shall not be subject to forfeiture, surrender, claw-back, transfers, disposals, exchanges or earn-outs for any reason on the Assigned Securities. Insider acknowledges and agrees that any earn-outs, forfeitures, transfers, restrictions, amendments or arrangements that may be imposed on the Founder Shares held by the Insider shall not apply to the Assigned Securities and the terms and conditions applicable to the Assigned Securities and the Economic Interest shall not be changed or the number reduced as a result of any such earn-outs, forfeitures, transfers, restrictions, amendments or arrangements.

1.6. Delivery of Shares; Other Documents. At the time of the transfer of Assigned Securities hereunder, the Insider shall deliver the Assigned Securities to the Investor by transfer of book-entry shares effected through PVAC’s transfer agent. The parties to this Agreement agree to execute, acknowledge and deliver such further instruments and to do all such other acts, as may be necessary or appropriate to carry out the purposes and intent of this Agreement.

1.7. Assignment of Registration Rights. Concurrent with the transfer of Assigned Securities to the Investor under this Agreement and contingent upon the consummation of the closing of the Initial Business Combination, the Insider shall assign all of its rights, duties and obligations to the Investor with respect to the Assigned Securities under that certain Registration Rights Agreement, dated November 30, 2021, by and among PVAC and the other parties thereto (as it exists on the date of the Agreement, the “Registration Rights Agreement”), and hereby represents and confirms to the Investor that, upon the Investor’s receipt of the Assigned Securities and compliance with the last sentence of this Section 1.7, (i) the Investor shall become a “Holder” under the Registration Rights Agreement and (ii) the Assigned Securities shall be “Registrable Securities” under the Registration Rights Agreement. This Agreement constitutes the Insider’s written notice to PVAC of such assignment in accordance with the Registration Rights Agreement (if required). The Investor shall execute a Joinder (as defined below) set forth as Exhibit B to this Agreement contemporaneously with the closing of the Initial Business Combination and transfer of the Assigned Securities from the Insider to the Investor, pursuant to which, Investor will be bound by the terms and provisions of the Registration Rights Agreement as a “Holder” thereunder with respect to the Assigned Securities (upon acquisition thereof) as “Registrable Securities” thereunder.

1.8. Joinder to Letter Agreement and Registration Rights Agreement. In connection with the transfer of the Assigned Securities to the Investor, the Investor shall execute a joinder to the Letter Agreement and the Registration Rights Agreement in substantially the form attached here to as Exhibit B (the “Joinder”) pursuant to which the Investor shall agree with PVAC, in accordance with Section 9 of the Letter Agreement, to be bound by the transfer restrictions set forth in, and to be subject to, solely Section 9 of the Letter Agreement (but subject to the Carve-Out), solely with respect to the Assigned Securities and to be bound by the terms and provisions of the Registration Rights Agreement as a “Holder” thereunder with respect to the Assigned Securities (upon acquisition thereof) as “Registrable Securities” thereunder and PVAC hereby agrees to execute the Joinder contemporaneously with the closing of the Initial Business Combination and transfer of the Assigned Securities from the Insider to the Investor.

1.9. Termination. This Agreement and each of the obligations of the undersigned shall terminate on the earlier of (a) the failure of PVAC’s shareholders to approve the Proposals at the Meeting or the determination of the Company not to proceed to effect the Extension, (b) the fulfillment of all obligations of parties hereto, (c) the liquidation or dissolution of PVAC, (d) the mutual written agreement of the parties hereto; or (e) if the Investor exercises its Redemption Rights with respect to any Investor Shares in connection with the Meeting and such Investor Shares are actually redeemed in connection with the Meeting. Notwithstanding any provision in this Agreement to the contrary, the Insider’s obligation to transfer the Assigned Securities or assign the Economic Interest to the Investor shall be conditioned on (i) the satisfaction of the conditions set forth in Section 1.2, Section 1.7, and Section 1.8 hereof and (ii) the Investor Shares not being redeemed in connection with the Meeting.

2. Assignment of Economic Interest.

2.1. Upon satisfaction of the conditions set forth in Section 1.1, the Insider hereby assigns to the Investor all of its economic interest in and to that number of Assigned Securities set forth on Exhibit A (the “Economic Interest”), subject to adjustment as set forth in Section 2.2. The Economic Interest represents the Insider’s right to receive dividends and other distributions with respect to that number of Assigned Securities set forth on Exhibit A represented by the Founder Shares held directly by the Insider.

2.2. The Investor acknowledges and agrees that it is not a member of the Insider, it has no right to vote on matters of the Insider as a result of the Assigned Securities or Economic Interest, or to vote with respect to any Assigned Securities, and it has no right to vote Assigned Securities prior to transfer of any such shares to the Investor pursuant to this Agreement.

2.3. The Investor acknowledges and agrees that if it has a right pursuant to its Economic Interest to receive any dividends or other distributions paid in Ordinary Shares or other non-cash property, the Insider shall transfer all of its right, title and interest in such dividends or distributions concurrently with the transfer of the Assigned Securities to the Investor pursuant to Section 1.

2.4. If the conditions to the transfer of the Founder Shares in Section 1 are not satisfied with respect to any Founder Shares, then the Investor shall automatically assign its Economic Interests in such Founder Shares back to the Insider, for no consideration.

3. Representations and Warranties of the Investor. The Investor represents and warrants to, and agrees with, the Insider that:

3.1. No Government Recommendation or Approval. The Investor, in making the decision pursuant to this Agreement, has not relied upon any oral or written representations or assurances from the Insider or any of the Insider’s or the Company’s officers, directors, partners or employees or any other representatives or agents except as provided in this Agreement. The Investor understands that no federal or state agency has passed upon or made any recommendation or endorsement of the offering of the Assigned Securities.

3.2. Accredited Investor.

3.4.3. The Investor agrees only with PVAC, solely for the benefit of and, notwithstanding anything else herein, enforceable only by PVAC, to waive any right that it may have to elect to have PVAC redeem any Investor Shares and agrees not to redeem or otherwise exercise any right to redeem, the Investor Shares and to reverse and revoke any prior redemption elections made with respect to the Investor Shares, in each case, solely in connection with the Proposals. For the avoidance of doubt, nothing in this Agreement is intended to restrict or prohibit the Investor’s ability to redeem any Public Shares other than the Investor Shares, or to trade or redeem any Public Shares (other than the Investor Shares) in its discretion and at any time or trade or redeem any Investor Shares in its discretion and at any time after the date of the Meeting.

3.4.4. The Investor acknowledges and understands that the Assigned Securities are being offered in a transaction not involving a public offering in the United States within the meaning of the Securities Act and have not been registered under the Securities Act and, if in the future the Investor decides to offer, resell, pledge or otherwise transfer Assigned Securities, such Assigned Securities may be offered, resold, pledged or otherwise transferred only (A) pursuant to an effective registration statement filed under the Securities Act, (B) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (C) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. The Investor agrees that, if any transfer of the Assigned Securities or any interest therein is proposed to be made (other than pursuant to an effective registration statement or Rule 144 under the Securities Act), as a condition precedent to any such transfer, the Investor may be required to deliver to PVAC an opinion of counsel (including internal counsel) satisfactory to PVAC that registration is not required with respect to the Assigned Securities to be transferred. Absent registration or another available exemption from registration, the Investor agrees it will not transfer the Assigned Securities.

3.4.5. The Investor hereby agrees only with PVAC, solely for the benefit of and, notwithstanding anything else herein, enforceable only by PVAC, that it shall ensure that neither it, nor any person or entity acting on its behalf or pursuant to any understanding with it, will allow the Investor Shares held by the Investor to be lent out or rehypothecated prior to the conclusion of the Meeting and confirms that it has notified its prime brokers with respect to this requirement and has received assurances from such prime brokers.

13. Independent Nature of Rights and Obligations. Nothing contained herein, and no action taken by any party pursuant hereto, shall be deemed to constitute the Investor and the Insider as, and the Insider acknowledges that the Investor and the Insider do not so constitute, a partnership, a limited partnership, a syndicate, an association, a joint venture or any other kind of entity, including but not limited to for the purpose of acquiring, holding, or disposing of securities of PVAC, or create a presumption that the Investor and the Insider are in any way acting in concert or as a group with respect to such obligations or the transactions contemplated by this Agreement or any matters, and the Insider acknowledges that the Investor and the Insider are not acting in concert or as a group, and the Insider shall not assert any such claim, with respect to such obligations or the transactions contemplated by this Agreement.

14. Most Favored Nation. In the event the Insider or PVAC has entered into or enters one or more other non-redemption agreements before or after the execution of this Agreement in connection with the Meeting, the Insider and PVAC represent that the terms of such other agreements are not materially more favorable in the aggregate to such other investors thereunder than the terms of this Agreement are in respect of the Investor. For the avoidance of doubt, the Insider and PVAC hereby acknowledge and agree that a ratio of Investor Shares to Assigned Securities in any such other non-redemption agreement that is more favorable to any other investor party to such other agreement than such ratio in this Agreement is to Investor would be materially more favorable to such other investor. In the event that another investor is afforded any such more favorable terms than the Investor, the Insider shall promptly inform the Investor of such more favorable terms in writing, and the Investor shall have the right to elect to have such more favorable terms included herein, in which case the parties hereto shall promptly amend this Agreement to effect the same.

IN WITNESS WHEREOF, the parties hereto have caused this Agreement to be duly executed as of the date first above written.

By executing this joinder, Investor hereby agrees, as of the date first set forth above, that Investor (i) shall become a party to that certain Letter Agreement, dated November 30, 2021, entered into by the Company and others in connection with the Company’s initial public offering (as amended and as it exists on the date of the Agreement, the “Letter Agreement”), in accordance with Section 7 of the Letter Agreement, but shall not be bound by, and shall not, subject to the acknowledgment below be subject to the transfer restrictions set forth under, Section 7 of the Letter Agreement with respect to its Assigned Securities. The Company acknowledges and agrees that the voting, Trust Account (as defined in the Letter Agreement) and liquidating distribution restrictions contained in the Letter Agreement (or any other restrictions contained therein) shall only apply to the Assigned Securities and not any Public Shares (including the Investor Shares), and that the obligations with respect to the “Ordinary Shares” referenced in Sections 1 and 2 of the Letter Agreement shall not apply to or restrict Investor, other than with respect to the Assigned Securities; and (ii) shall become a party to that certain Registration Rights Agreement, dated November 30, 2021, by and among the Company and the other signatories thereto (as amended and as it exists on the date of the Agreement, the “Registration Rights Agreement”), and shall be bound by the terms and provisions of the Registration Rights Agreement as a Holder (as defined therein) and entitled to the rights of a Holder under the Registration Rights Agreement and the Assigned Securities (together with any other equity security of the Company issued or issuable with respect to any such Assigned Securities by way of a share dividend or share subdivision or in connection with a combination of shares, recapitalization, merger, consolidation or reorganization) shall be “Registrable Securities” thereunder.

For the purposes of clarity, it is expressly understood and agreed that each provision contained herein, in the Letter Agreement (to the extent applicable to Investor) and the Registration Rights Agreement is between the Company and Investor, solely, and not between and among Investor and the other shareholders of the Company signatory thereto.

This joinder may be executed in two or more counterparts, and by facsimile, all of which shall be deemed an original and all of which together shall constitute one instrument.
