 a product that is identical to TuHURA’s product, if the competitor’s product is made by a process outside the scope of the patented method.

The strength of patents in the biotechnology and pharmaceutical field can be uncertain, and evaluating the scope of such patents involves
complex legal and scientific analyses. The patent applications that TuHURA owns or in-license may fail to result in issued patents with claims that cover its product candidates, methods of making its product
candidates, or uses thereof in the United States or in other foreign countries. Even if the patents do successfully issue, third parties may challenge the validity, enforceability, or scope thereof, which may result in such patents being narrowed,
invalidated, or held unenforceable. Furthermore, even if they are unchallenged, TuHURA’s patents and patent applications may not adequately protect its intellectual property or prevent others from designing their products to avoid being covered
by its claims. If the breadth or strength of protection provided by the patents and patent applications TuHURA holds with respect to its product candidates is threatened, this could dissuade companies from collaborating with TuHURA to develop, and
could threaten TuHURA’s ability to commercialize, TuHURA’s product candidates. Further, if TuHURA encounters delays in its clinical trials, the period of time during which TuHURA could market its product candidates under patent protection
would be reduced. Because patent applications in the United States and most other countries are confidential for a period of time after filing, TuHURA cannot be certain that it was the first to file any patent application related to its product
candidates.

Confidentiality agreements with employees and third parties may not prevent unauthorized disclosure of trade secrets and other proprietary information.

In addition to the protection afforded by patents, TuHURA seeks to rely on trade secret protection and
confidentiality agreements to protect proprietary know-how that is not patentable or that TuHURA elects not to patent, processes for which patents are difficult to enforce, and any other elements of its
product discovery and development processes that involve proprietary know-how, information, or technology that is not covered by patents. Trade secrets, however, may be difficult to protect. TuHURA seeks to
protect its proprietary processes, in part, by entering into confidentiality agreements with its employees, consultants, outside scientific advisors, contractors, and collaborators. Although TuHURA uses reasonable efforts to protect its trade
secrets, its employees, consultants, outside scientific advisors, contractors, and collaborators might intentionally
