 not recognize any gain or loss as a result of the consummation of
the Delaware Conversion, (2) the aggregate tax basis of shares of the resulting Delaware corporation’s common stock received in the Delaware Conversion will be equal to the aggregate tax basis of the shares of TuHURA Common Stock converted
therefor, and (3) the holding period of the shares of the resulting Delaware corporation’s common stock received in the Delaware Conversion will include the holding period of the shares of TuHURA Common Stock converted therefor.

No ruling will be sought from the IRS with respect to the United States federal income tax consequences of the Reincorporation, and no
assurance can be given that the United States federal income tax consequences described above will not be challenged by the IRS or, if challenged, will be upheld by a court. Accordingly, U.S. holders are urged to consult their tax advisors regarding
the tax consequences of the Delaware Conversion.

EACH STOCKHOLDER IS URGED TO CONSULT HIS OR HER OWN TAX ADVISORS TO DETERMINE THE
PARTICULAR FEDERAL TAX CONSEQUENCES TO SUCH STOCKHOLDER OF THE DELAWARE CONVERSION, AS WELL AS THE APPLICABILITY AND EFFECT OF STATE, LOCAL, FOREIGN AND OTHER LAWS.

Accounting Treatment of the Delaware Conversion

The Delaware Conversion has no effect from an accounting perspective because there is no change in the entity as a result of the Delaware
Conversion. Accordingly, the historical consolidated financial statements of TuHURA as a Nevada corporation previously reported to the SEC as of and for all periods through the date of this joint proxy statement/prospectus remain the consolidated
financial statements of the resulting Delaware corporation.

Regulatory Approval

The Delaware Conversion will not be consummated until after TuHURA stockholder approval is obtained. TuHURA will obtain all required consents
of governmental authorities, including the filing of the Nevada Articles of Conversion, the Delaware Certificate of Conversion and the Delaware Charter.

Approval Requirements

The Delaware
Conversion Proposal requires the affirmative vote of holders of a majority of the total voting shares outstanding. Accordingly, abstentions and broker non-votes, if any, will have the effect of a vote
“AGAINST” the Delaware Conversion Proposal.

The completion of the Mergers is not conditioned upon the
approval of the Delaware Conversion.

TUHURA’S BOARD OF DIRECTORS UNANIMOUSLY RECOMMENDS THAT ITS STOCKHOLDERS VOTE “FOR” THE DELAWARE CONVERSION PROPOSAL (TU
