Item 5.07 Submission of Matters to a Vote of Security Holders.

On December 30, 2025, the Company held a special meeting of its stockholders (the “special meeting”). On December 15, 2025, the record date for the special meeting, there were 2,848,313 shares of common stock of the Company entitled to be voted at the special meeting, approximately 83.64% of which were represented in person or by proxy at the special meeting.

The final results for each of the matters submitted to a vote of the Company’s stockholders at the special meeting are as follows:

1. Charter Amendment Proposal

The stockholders approved the proposal to amend (the “Charter Amendment”) the Company’s Charter by allowing the Company to extend (the “Extension”) the date by which it has to consummate a business combination (the “Combination Period”) with a target (the “Target”) for up to an additional three months, from December 30, 2025, to up to March 30, 2026. The voting results were as follows:

2. Trust Amendment Proposal

The stockholders approved the proposal to amend (the “Trust Amendment” and together with the Charter Amendment, the “Extensions”) the Trust Agreement, allowing the Company to extend the Combination Period for up to an additional three months, from December 30, 2025, to up to March 30, 2026 (the “Trust Amendment”), for no contribution to the trust account. The voting results were as follows:

As there were sufficient votes at the time of the special meeting to approve each of the above proposals, the Adjournment Proposal, which had been previously voted on by proxy, was not presented to stockholders at the special meeting.

Item 8.01. Other Events.

In connection with the votes to approve the Extensions, no holders of shares of common stock of the Company exercised their right to redeem their shares for cash at a redemption price of approximately $11.45 per share. Accordingly, no shares were redeemed, and no funds were distributed from the trust account in connection with the Extensions. As a result, approximately $6.46 million remained in the trust account as of December 30, 2025 (less funds that may be withdrawn to pay taxes).

The Company has determined that it will not utilize any funds from its trust account to pay any potential excise taxes that may become due upon a redemption of the Company’s public shares in connection with a liquidation of the Company if it does not effect a business combination prior to its termination date.

The Company has also determined that it will not utilize any funds from its trust account to pay any dissolution expenses in connection with the liquidation of the Trust Account and of the Company if it does not effect a business combination prior to its termination date.

Cautionary Statement Regarding Forward-Looking Statements

Certain statements made in this Current Report on Form 8-K are “forward looking statements” within the meaning of the “safe harbor” provisions of the United States Private Securities Litigation Reform Act of 1995. Such “forward-looking statements” with respect to the proposed transaction between a target and WTMA include statements regarding the benefits of the transaction, the anticipated timing of the transaction and the products and markets of a target. These forward-looking statements generally are identified by the words “believe,” “project,” “expect,” “anticipate,” “estimate,” “intend,” “strategy,” “future,” “opportunity,” “plan,” “may,” “should,” “will,” “would,” “will be,” “will continue,” “will likely result,” and similar expressions. Forward-looking statements are predictions, projections and other statements about future events that are based on current expectations and assumptions and, as a result, are subject to risks and uncertainties. Many factors could cause actual future events to differ materially from the forward-looking statements in this Current Report on Form 8-K, including but not limited to: (i) the risk that the transaction may not be completed in a timely manner or at all, which may adversely affect the price of WTMA’s securities, (ii) the risk that the transaction may not be completed by WTMA’s business combination deadline and the potential failure to obtain an extension of the business combination deadline if sought by WTMA, (iii) the failure to satisfy the conditions to the consummation of the transaction, including the adoption of a Merger Agreement by the shareholders of WTMA, the satisfaction of the minimum amount in the trust account, if any, following redemptions by WTMA’s public shareholders and the receipt of certain governmental and regulatory approvals, (iv) the potential lack of a third party valuation in determining whether or not to pursue the proposed transaction, (v) the inability to complete a PIPE investment, (vi) the occurrence of any event, change or other circumstance that could give rise to the termination of a Merger Agreement, (vii) the effect of the announcement or pendency of the transaction on a target’s business relationships, operating results, and business generally, (viii) risks that the proposed transaction disrupts current plans and operations of a target and potential difficulties in employee retention as a result of the transaction, (ix) the outcome of any legal proceedings that may be instituted against a target or against WTMA related to a Merger Agreement or the proposed transaction, (x) the ability to maintain the listing of WTMA’s securities on a national securities exchange, (xi) the price of WTMA’s securities may be volatile due to a variety of factors, including changes in the competitive and regulated industries in which WTMA plans to operate or a target operates, variations in operating performance across competitors, changes in laws and regulations affecting WTMA’s or a target’s business, a target’s inability to implement its business plan or meet or exceed its financial projections and changes in the combined capital structure, (xii) changes in general economic conditions, including as a result of the COVID-19 pandemic, and (xiii) the ability to implement business plans, forecasts, and other expectations after the completion of the proposed transaction, and identify and realize additional opportunities. The foregoing list of factors is not exhaustive. You should carefully consider the foregoing factors and the other risks and uncertainties described in a registration statement on Form S-4 following identification of a target and execution of a Merger Agreement, the proxy statement/prospectus and other documents filed or that may be filed by WTMA from time to time with the SEC. These filings identify and address other important risks and uncertainties that could cause actual events and results to differ materially from those contained in the forward-looking statements. Forward-looking statements speak only as of the date they are made. Readers are cautioned not to put undue reliance on forward-looking statements, and a target and WTMA assume no obligation and do not intend to update or revise these forward-looking statements, whether as a result of new information, future events, or otherwise. Neither a target nor WTMA gives any assurance that either a target or WTMA, or the combined company, will achieve its expectations.
