Merger Proceedings

In connection with the Merger, two actions were filed against us and our board of directors in the Supreme Court for the State of New York, County of New York, captioned Smith v. Ikena Oncology, Inc., et al., No. 653576/2025 (filed June 12, 2025) and Kent v. Ikena Oncology, Inc., et al., No. 653588/2025 (filed June 13, 2025) (collectively, the “Complaints”). The Complaints alleged that the defendants filed or caused to be filed a materially incomplete and misleading registration statement with the SEC and asserts claims under New York common law for negligent misrepresentation and concealment and negligence. In addition, we have received five additional demands from purported stockholders seeking additional disclosures in the registration statement (collectively, the “Demands”). On February 27, 2026, the Complaints were voluntarily dismissed and we have received no additional outreach from the purported stockholders who sent the Demands.

Other Legal Proceedings

From time to time, we may become involved in litigation or other legal proceedings. We are not currently a party to any litigation or legal proceedings that, in the opinion of our management, are probable to have a material adverse effect on our business. Regardless of outcome, litigation can have an adverse impact on our business, financial condition, results of operations and prospects because of defense and settlement costs, diversion of management resources and other factors.
