Item 1.01. Entry into a Material Definitive Agreement.

Promissory Note

As disclosed in the definitive proxy statement filed by WinVest Acquisition Corp. (the “Company”) with the Securities and Exchange Commission (the “SEC”) on June 2, 2025 (the “Proxy Statement”), relating to a special meeting of stockholders (the “Extension Meeting”), WinVest SPAC LLC, the Company’s sponsor (the “Sponsor”), agreed that if the Extension Amendment Proposal (as defined below) was approved at the Extension Meeting, it or one or more of its affiliates, members or third-party designees would lend to the Company up to $90,000 to be deposited into the trust account (the “Trust Account”) established in connection with the Company’s initial public offering (the “IPO”).

On June 16, 2025, the stockholders of the Company approved the Extension Amendment Proposal at the Extension Meeting. Accordingly, on June 16, 2025, the Company issued an unsecured promissory note in the principal amount of $90,000 (the “Note”) to the Sponsor, pursuant to which the Sponsor agreed to loan to the Company up to $90,000 in connection with the extension of the date (the “Termination Date”) by which the Company must consummate an initial business combination (“Business Combination”). The Note does not bear interest and matures upon the earlier of (a) the closing of a Business Combination and (b) the Company’s liquidation. In the event that the Company does not consummate a Business Combination, the Note will be repaid only from amounts remaining outside of the Trust Account, if any.

The Company has caused $30,000 to be deposited into the Trust Account in connection with the first drawdown under the Note pursuant to the extension of the Termination Date to July 17, 2025 (the “Charter Extension Date”), and will cause an additional $30,000 to be deposited into the Trust Account for each subsequent Extension (as defined below) that is needed by the Company to complete a Business Combination. Such amounts will be distributed either to: (i) all of the holders of shares of the Company’s common stock, par value $0.0001 per share (“Common Stock”), issued as part of the units sold in the IPO (the “Public Shares”) upon the Company’s liquidation or (ii) holders of Public Shares who elect to have their shares redeemed in connection with the consummation of a Business Combination.

The foregoing description is qualified in its entirety by reference to the Note, a copy of which is attached as Exhibit 10.1 hereto and is incorporated herein by reference.

Trust Agreement Extension Amendment

 At the Extension Meeting, the Company’s stockholders approved a proposal (the “Trust Amendment Proposal”) to amend the Investment Management Trust Agreement (the “Trust Agreement”), dated as of September 14, 2021, by and between the Company and Continental Stock Transfer and Trust Company (“Continental”), to extend the date on which Continental must liquidate the Trust Account (the “Liquidation Date”) from June 17, 2025 to July 17, 2025, and to allow the Company, without another stockholder vote, to further extend the Liquidation Date up to two times, for up to an additional one month each time, from July 17, 2025 to September 17, 2025, by causing $30,000 to be deposited into the Trust Account for each such extension (the “Trust Agreement Extension Amendment”). On June 16, 2025, the Company and Continental entered into the Trust Agreement Extension Amendment.

The foregoing description of the Trust Agreement Extension Amendment is a summary only and is qualified in its entirety by reference to the full text of the Trust Agreement Extension Amendment, a copy of which is attached as Exhibit 10.2 hereto and is incorporated by reference herein.

Trust Agreement Disbursement Amendment

On June 17, 2025, the Company and Continental entered into an amendment to the Trust Agreement (the “Trust Agreement Disbursal Amendment”) to provide that in the event of the Company’s dissolution, up to $100,000 of interest income earned on the Trust Account may be used to cover the Company’s liquidation and dissolution expenses, consistent with the Company’s historic disclosure on the terms of the Trust Agreement.

The foregoing description of the Trust Agreement Disbursement Amendment is a summary only and is qualified in its entirety by reference to the full text of the Trust Agreement Disbursement Amendment, a copy of which is attached as Exhibit 10.3 hereto and is incorporated by reference herein.

Item 5.03. Amendments to Articles of Incorporation or Bylaws; Change in Fiscal Year.

At the Extension Meeting, the Company’s stockholders approved an amendment to the Company’s amended and restated certificate of incorporation, as amended (the “Certificate of Incorporation,” and such amendment, the “Extension Amendment”), to extend the Termination Date from June 17, 2025 (the “Current Termination Date”) to the Charter Extension Date, and to allow the Company, without another stockholder vote, to elect to extend the Termination Date on a monthly basis for up to two times by an additional one month (or such shorter period as may be requested by the Sponsor) each time (each, an “Extension”) after the Charter Extension Date, by resolution of the Company’s board of directors, if requested by the Sponsor, and upon five days’ advance notice prior to the applicable Termination Date, until September 17, 2025, or a total of up to three months after the Current Termination Date, unless the closing of the Company’s Business Combination shall have occurred prior thereto (the “Extension Amendment Proposal”). Following stockholder approval of the Extension Amendment Proposal at the Extension Meeting, on June 17, 2025, the Company filed the Extension Amendment with the Delaware Secretary of State.

The foregoing description of the Extension Amendment is a summary only and is qualified in its entirety by reference to the full text of the Extension Amendment, a copy of which is attached hereto as Exhibit 3.1 and is incorporated by reference herein.

On June 16, 2025, the Company held the Extension Meeting to approve (i) the Extension Amendment Proposal, (ii) the Trust Amendment Proposal, and (iii) a proposal to adjourn the Extension Meeting, if necessary, in the event there were insufficient shares of Common Stock represented to constitute a quorum at the Extension Meeting or approve the Extension Amendment Proposal and the Trust Amendment Proposal (the “Adjournment Proposal”), each as more fully described in the definitive proxy statement filed by the Company with the Securities and Exchange Commission on June 2, 2025. 

Holders of 2,847,267 shares of Common Stock held of record as of May 30, 2025, the record date for the Extension Meeting, were present in person or by proxy, representing approximately 90.9% of the voting power of the shares of Common Stock issued and outstanding as of the record date for the Extension Meeting, and constituting a quorum for the transaction of business.
