Rezolute, Inc.

Our Risk Factor disclosures are set forth in Part I, Item 1A of our Annual Report on Form 10-K for the fiscal year ended June 30, 2025 filed with the Securities and Exchange Commission on September 17, 2025. The risk factors included in our 2025 Form 10-K have not materially changed, except as reflected in the following new risk factors:

Risks Related to our Clinical Trials

The development of ersodetug could be halted or significantly delayed for various reasons

Ersodetug is vulnerable to the risks of failure inherent in the drug development process. Our sunRIZE trial failed to meet its primary and secondary endpoints, and we may not be able to obtain regulatory approval for commercialization. We will be meeting with the FDA prior to the end of calendar Q1 2026 to discuss the study results and discuss a potential path forward. There can no guarantee of the outcome of our meeting with the FDA and the path forward, if any, which may require us to expend additional capital or to conduct additional studies and clinical trials which we may be unable to do.

Our preclinical studies or early clinical trials of our product candidates, whether conducted by us or third parties, may not necessarily be predictive of the results of later clinical trials that we conduct. For example, despite promising results in our early clinical trials of ersodetug, our sunRIZE trial failed to meet its primary and secondary endpoints. Similarly, even if we are able to complete our planned upLIFT trial, positive results from earlier clinical trial may not be replicated in our subsequent preclinical studies or clinical trials or in real-world results.

Many companies in the pharmaceutical and biotechnology industries have suffered significant setbacks in late-stage clinical trials after achieving positive results in early-stage development, and we cannot be certain that we will not face further setbacks for any future product candidates. These setbacks have been caused by, among other things, preclinical findings made while clinical trials were underway or safety or efficacy observations made in preclinical studies and clinical trials, including previously unreported adverse events. Moreover, preclinical and clinical data are often susceptible to varying interpretations and analyses and many companies that believed their product candidates performed satisfactorily in preclinical studies and clinical trials nonetheless failed to obtain FDA, or comparable non-U.S. regulatory authority approval. Furthermore, the approval policies or regulations of the FDA or comparable non-U.S. regulatory authorities may significantly change in a manner that may render our clinical data insufficient for approval, which may lead to the FDA or comparable non-U.S. regulatory authorities delaying, limiting or denying approval of our product candidates.

Interim, “topline” and preliminary data from clinical trials may change as more data become available, are not necessarily predictive of the final results of the completed study or the results of other ongoing or future studies and are subject to audit and verification procedures that could result in material changes.

From time to time, we may announce, publish or report preliminary, topline or interim data from our clinical trials. Such data are subject to the risk that one or more of the clinical outcomes may materially change as patients continue progressing through the study (for example, in oncology studies, a patient may progress from a complete or partial response to progressive disease), as patient enrollment continues and/or as more patient data become available, and such data may not be indicative of final data from such trials, data from future trials or real-world results. In addition, such data may remain subject to audit confirmation and verification procedures that may result in the final data being materially different from the preliminary, topline or interim data disclosed. As a result, all preliminary, topline and interim data should be viewed with caution until the final data are available. Material adverse differences between preliminary, topline or interim data and final data could significantly harm our business, financial condition, cash flows and results of operations.

We may become the subject of litigation.

Following the release of the results of our sunRIZE trial our stock price suffered a decline. As a result, plaintiffs law firms have announced investigations into potential securities laws violations based on allegations related to the results of the sunRIZE trial. While we believe these allegations are without merit, and no litigation has been commenced to date regarding such allegations, we still face the potential for litigation to be initiated against us. While we would vigorously defend against any such litigation, regardless of outcome, litigation can be costly and time-consuming, divert the attention of our management team, adversely impact our reputation and brand, and if a plaintiff claim were successful, could result in significant liability, all of which could harm our business and financial condition.
