The Sponsor (including its representatives and affiliates) and Denali’s directors and officers are, or may in the future become, affiliated with entities that are engaged in a similar business to Denali. The Sponsor and Denali’s directors and officers are not prohibited from sponsoring, or otherwise becoming involved with, any other blank check companies prior to Denali completing its initial business combination. Moreover, certain of Denali’s directors and officers have time and attention requirements for investment funds of which affiliates of the Sponsor are the investment managers. Denali’s directors and officers also may become aware of business opportunities which may be appropriate for presentation to Denali, and the other entities to which they owe certain fiduciary or contractual duties. Accordingly, they may have had conflicts of interest in determining to which entity a particular business opportunity should be presented. These conflicts may not be resolved in Denali’s favor and such potential business opportunities may be presented to other entities prior to their presentation to Denali, subject to applicable fiduciary duties under Cayman Islands law. 208

The Sponsor has agreed to vote in favor of the Business Combination, regardless of how Denali’s public
shareholders vote. Unlike some other blank check companies in which the initial shareholders agree to vote their founder shares in accordance with the majority of the votes cast by the public shareholders in connection with an initial business
combination, the Sponsor has agreed to, among other things, vote in favor of the Merger Agreement and the transactions contemplated thereby. As of the date of this proxy statement/prospectus, the Sponsor owns approximately 74.2% of the issued and
outstanding Denali Ordinary Shares.
