Comparison of TuHURA Stockholders’ Rights Before and After the Delaware Conversion

For a detailed comparison of TuHURA stockholders’ rights, which includes the Kineta stockholders who receive shares of TuHURA Common Stock
as Merger Consideration upon the completion of the Mergers, assuming approval of the Delaware Conversion, please refer to the section entitled “Comparison of Stockholders’ Rights”.

As a result of differences between the NRS and the DGCL, as well as differences between the TuHURA Charter and the TuHURA Bylaws, on the one
hand, and the Delaware Charter and the Delaware Bylaws, on the other hand, the Delaware Conversion will effect changes in the rights of TuHURA’s stockholders. The summary table in the section entitled “Comparison of Stockholders’
Rights” provides a comparison of the material differences between the NRS and the DGCL, the current TuHURA Charter and the Delaware Charter, and the TuHURA Bylaws and the Delaware Bylaws. The summary does not purport to be a complete statement
of the respective rights of TuHURA stockholders before and after the Delaware Conversion, and is qualified in its entirety by reference to the NRS and the DGCL, to the TuHURA Charter and the TuHURA Bylaws, and to the Delaware Charter and the
Delaware Bylaws. The Delaware Charter and the Delaware Bylaws are attached as annexes to this joint proxy statement/prospectus.
