EXPLANATORY NOTE

On July 25, 2025 (the “Closing Date”), the Delaware corporation formerly known as “Ikena Oncology, Inc.” (“Ikena”) completed its previously announced merger with Inmagene Biopharmaceuticals, a privately held exempted company with limited liability incorporated and existing under the laws of the Cayman Islands (“Legacy Inmagene”). The transaction was completed in accordance with the terms of the Agreement and Plan of Merger, dated as of December 23, 2024 (the “Merger Agreement”), by and among Ikena, Insight Merger Sub I, an exempted company with limited liability incorporated and existing under the laws of the Cayman Islands and a direct, wholly owned subsidiary of Ikena (“Merger Sub I”), Insight Merger Sub II, an exempted company with limited liability incorporated and existing under the laws of the Cayman Islands and a direct, wholly owned subsidiary of Ikena (“Merger Sub II”), and Legacy Inmagene, providing for the merger of Merger Sub I with and into Legacy Inmagene, with Legacy Inmagene surviving as a wholly owned subsidiary of Ikena (such transaction, the “First Merger”), and the subsequent merger of the surviving entity of the First Merger with and into Merger Sub II, with Merger Sub II surviving as a wholly owned subsidiary of Ikena (the “Second Merger” and, together with the First Merger, the “Merger”). In addition, on July 25, 2025, Ikena changed its name from “Ikena Oncology, Inc.” to “ImageneBio, Inc.”

Summary of the Material and Other Risks Associated with Our Business

Our business is subject to numerous material and other risks and uncertainties to be aware of in evaluating our business. These risks include, but are not limited to, the following:

•

We are a clinical-stage biopharmaceutical company with a limited operating history, which may make it difficult to evaluate our current business and predict our future performance;

•

We expect to incur significant losses for the foreseeable future and may never achieve or maintain profitability;

•

We will need to obtain substantial additional funding to complete the development and any commercialization of olevaprubart and any future product candidates, which may cause dilution to our stockholders. If we are unable to raise this capital when needed, we may be forced to delay, reduce or eliminate our research and development programs or other operations;

•

Our business is entirely dependent on the success of olevaprubart for the treatment of atopic dermatitis (“AD”) and alopecia areata (“AA”) and for other potential indications;

•

Clinical trials are expensive, time-consuming, difficult to design and implement, and have an uncertain outcome. Further, we may encounter substantial delays in our clinical trials;

•

If we breach our current or future licenses or other intellectual property-related agreements for olevaprubart or any future product candidates or otherwise experience disruptions to our business relationships with our current or future licensors, we could lose the ability to continue the development and commercialization of our product candidates;

•

Our rights to develop and commercialize olevaprubart are subject, in part, to the terms and conditions of licenses granted to us by others;

•

We rely on third parties for the manufacture of olevaprubart for development, and expect to continue to do so for the foreseeable future. Our current and anticipated future dependence upon third parties for the manufacture of olevaprubart or any future product candidates increases the risk that we will not have sufficient quantities of olevaprubart or any future product candidates, or such quantities at an acceptable cost, which could delay, prevent or impair our development or commercialization efforts and could impact future profit margins;

•

We face substantial competition from other pharmaceutical and biotechnology companies, and our operating results may suffer if we fail to compete effectively;

•

The regulatory approval process of the United States Food and Drug Administration (“FDA”) and comparable foreign regulatory authorities is lengthy, time-consuming and inherently unpredictable, and even if we complete the necessary clinical trials, we cannot predict when, or if, we will obtain regulatory approval for olevaprubart or any future product candidates, and any such regulatory approval may be for a more narrow indication than we seek;

•

Even if we receive regulatory approval of olevaprubart or any future product candidates, we will be subject to ongoing regulatory obligations and continued regulatory review, which may result in significant additional expense and we may be subject to penalties if we fail to comply with regulatory requirements or experience unanticipated problems with olevaprubart or any future product candidates;

•

If we are unable to obtain and maintain patent protection for olevaprubart or any future product candidates or if the scope of the patent protection obtained is not sufficiently broad, we may not be able to compete effectively in our markets;

•

Our future success depends on our ability to retain our key personnel and to attract, retain and motivate qualified personnel;

•

The market price of our common stock is expected to be volatile;

•

We will incur costs and demands upon management as a result of complying with the laws, rules and regulations affecting public companies;

•

Substantial future sales of shares of our common stock could adversely affect the market price of such shares;

•

If equity research analysts do not publish research or reports, or publish unfavorable research or reports, about us, our business or our market, our stock price and trading volume could decline; and

•

We identified a material weakness in our internal control over financial reporting. If we fail to remediate this material weakness, or if we identify additional material weaknesses in the future or otherwise fail to maintain effective internal control over financial reporting in the future, we may not be able to accurately or timely report our financial condition or results of operations, which may adversely affect investor confidence in us and, as a result, the value of our common stock.

The material and other risks summarized above should be read together with the text of the full risk factors in the “Risk Factors” section and with the other information set forth in this Quarterly Report, including our condensed consolidated financial statements and the related notes, as well as with other documents that we file with the Securities and Exchange Commission (the “SEC”). If any such material and other risks and uncertainties actually occur, our business, prospects, financial condition and results of operations could be materially and adversely affected. The risks summarized above or described in full in the “Risk Factors” section, are not the only risks that we face. Additional risks and uncertainties not currently known to us, or that we currently deem to be immaterial may also materially adversely affect our business, prospects, financial condition and results of operations.
