Item 1.01. Entry into a Material Definitive Agreement.

As previously disclosed in the Current Report on Form 8-K filed by Denali Capital Acquisition Corp. (“Denali”) with the Securities and Exchange Commission (the “SEC”) on September 5, 2024 (the “Current Report”), on August 30, 2024, Semnur Pharmaceuticals, Inc. (“Semnur”), a Delaware corporation and wholly owned subsidiary of Scilex Holding Company (“Scilex”), entered into an agreement and plan of merger (the “Merger Agreement”) with Denali, and Denali Merger Sub Inc., a Delaware corporation and wholly owned subsidiary of Denali (“Merger Sub”), pursuant to which, among other things, Merger Sub will merge with and into Semnur with Semnur surviving the merger as a wholly owned subsidiary of Denali (the “Merger”). The Merger and the other transactions contemplated by the Merger Agreement are hereinafter referred to as the “Business Combination”. All capitalized terms used and not otherwise defined herein shall have the meanings set forth in the Amendment (as defined below) and the Merger Agreement.

On April 16, 2025, Denali entered into Amendment No. 1 to the Merger Agreement with Semnur and Merger Sub (the “Amendment”).

The Amendment amends the Merger Agreement to, among other things, (i) modify certain covenants of the parties to address the de-listing of the Parent Units, Class A Shares and Parent Warrants (the “Parent Securities”) from the Nasdaq Capital Market and subsequent quotation on the OTC Markets Group, Inc. (the “OTC Markets”), (ii) require Denali to amend its organizational documents to extend the period of time within which Denali can complete a business combination to December 11, 2025 or such other date that is mutually agreed to by Semnur and Denali, and (iii) extend the Outside Date to September 30, 2025; provided that if an Extension Amendment (as defined in the Merger Agreement, as amended by the Amendment) shall be in effect, the Outside Date shall be the Extension Date.

The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the Amendment, a copy of which is filed with this Current Report on Form 8-K as Exhibit 2.1 hereto, and is incorporated herein by reference.

Additional Information

In connection with the Business Combination, Denali filed with the SEC a Registration Statement on Form S-4 (the “Denali Registration Statement”), which includes a preliminary prospectus and preliminary proxy statement. Denali will mail a definitive proxy statement/final prospectus and other relevant documents to its shareholders. This communication is not a substitute for the Denali Registration Statement, the definitive proxy statement/final prospectus or any other document that Denali will send to its shareholders in connection with the Business Combination. Investors and security holders of Denali are advised to read the proxy statement/prospectus in connection with Denali’s solicitation of proxies for its extraordinary general meeting of shareholders to be held to approve the Business Combination (and related matters) because the proxy statement/prospectus contains important information about the Business Combination and the parties to the Business Combination. The definitive proxy statement/final prospectus will be mailed to shareholders of Denali as of a record date to be established for voting on the Business Combination. Shareholders will also be able to obtain copies of the proxy statement/prospectus, without charge, once available, at the SEC’s website www.sec.gov or by directing a request to: 437 Madison Avenue, 27^th Floor, New York, New York 10022.

Participants in the Solicitation

Denali, Semnur and their respective directors, executive officers, other members of management and employees, under SEC rules, may be deemed to be participants in the solicitation of proxies of Denali’s shareholders in connection with the Business Combination. Investors and security holders may obtain more detailed information regarding the names and interests in the Business Combination of Denali’s directors and officers in Denali’s filings with the SEC, including the Denali Registration Statement, which includes the proxy statement of Denali for the Business Combination, and such information and names of Semnur’s directors and executive officers are also included in the Denali Registration Statement, which includes the proxy statement of Denali for the Business Combination.

Forward-Looking Statements

This Report includes forward looking statements that involve risks and uncertainties. Forward-looking statements are statements that are not historical facts and may be accompanied by words that convey projected future events or outcomes, such as “believe,” “may,” “will,” “estimate,” “continue,” “anticipate,” “intend,” “expect,” “should,” “would,” “plan,” “predict,” “potential,” “seem,” “seek,” “future,” “outlook” or variations of such words or by expressions of similar meaning. These forward-looking statements include, but are not limited to, statements regarding future events, the Business Combination between Semnur and Denali, the estimated or anticipated future results and benefits of the combined company following the Business Combination, including the likelihood and ability of the parties to successfully consummate the Business Combination, future opportunities for the combined company, and other statements that are not historical facts. These statements are based on the current expectations of management of Denali and are not predictions of actual performance. These forward-looking statements are provided for illustrative purposes only and are not intended to serve as, and must not be relied on, by any investor as a guarantee, an assurance, a prediction or a definitive statement of fact or probability. Actual events and circumstances are difficult or impossible to predict and will differ from assumptions. Many actual events and circumstances are beyond the control of Denali. These statements are subject to a number of risks and uncertainties regarding Denali’s businesses and the Business Combination, and actual results may differ materially. These risks and uncertainties include, but are not limited to, general economic, political and business conditions; the inability of the parties to consummate the Business Combination or the occurrence of any event, change or other circumstances that could give rise to the termination of the Merger Agreement; the outcome of any legal proceedings that may be instituted against the parties following the announcement of the Business Combination; the receipt of an unsolicited offer from another party for an alternative business transaction that could interfere with the Business Combination; the risk that the approval of the stockholders of Semnur or the shareholders of Denali for the potential transaction is not obtained; failure to realize the anticipated benefits of the Business Combination, including as a result of a delay in consummating the potential transaction or difficulty in integrating the businesses of Semnur or Denali; the risk that the Business Combination disrupts current plans and operations as a result of the announcement and consummation of the Business Combination; the ability of the combined company to grow and manage growth profitably and retain its key employees; the amount of redemption requests made by Denali’s shareholders; the inability to obtain or maintain the listing of the post-acquisition company’s securities on Nasdaq or OTC Markets following the Business Combination; and costs related to the Business Combination. There may be additional risks that Denali presently does not know or that Denali currently believes are immaterial that could also cause actual results to differ from those contained in the forward-looking statements. In addition, forward-looking statements provide Denali’s expectations, plans or forecasts of future events and views as of the date of this communication. Denali anticipates that subsequent events and developments will cause such assessments to change. However, while Denali may elect to update these forward-looking statements at some point in the future, Denali specifically disclaims any obligation to do so. These forward-looking statements should not be relied upon as representing Denali’s assessments as of any date subsequent to the date of this communication. Accordingly, undue reliance should not be placed upon the forward-looking statements.
