-vote occurs on an item when (a) a bank, broker or other nominee has discretionary authority to vote on one or more “routine” proposals to be voted on at a meeting of stockholders, but is not
permitted to vote on other “non-routine” proposals without instructions from the beneficial owner of the shares and (b) the beneficial owner fails to provide the bank, broker or other nominee
with such instructions. Under the NYSE rules, “non-routine” matters include the Authorized Share Increase Proposal (TuHURA Proposal 1), the Delaware Conversion Proposal (TuHURA Proposal 2), the
Director Election Proposal (TuHURA Proposal 3), the Executive Compensation Proposal (TuHURA Proposal 4) and the TuHURA Adjournment Proposal (TuHURA Proposal 6). TuHURA expects that the Auditor Ratification Proposal (TuHURA Proposal 5) will be
considered a “routine” matter to be voted on at the TuHURA special meeting, meaning, that if you hold your shares in street name and do not provide voting instructions to your brokerage firm, your brokerage firm may still be able to vote
your shares with respect to such proposals. If you hold your shares of TuHURA Common Stock in “street name,” your shares will not be represented and will not be voted on any “non-routine” matter (TuHURA Proposals, 1, 2, 3, 4 and
6) unless you affirmatively instruct your bank, broker or other nominee how to vote your shares in one of the ways indicated by your bank, broker or other nominee. It is therefore critical that you cast your vote by instructing your bank, broker or
other nominee on how to vote. Other than the Auditor Ratification Proposal, the NYSE rules governing brokers’ discretionary authority will not permit brokers to exercise discretionary authority regarding any of the other proposals to be voted on at the TuHURA special meeting.
