 of the Code General U.S. Federal Income Tax Consequences of the Mergers Subject to the discussions below regarding the receipt of cash in lieu of fractional shares, and assuming that the Mergers together qualify as a “reorganization” for U.S. federal income tax purposes and that the receipt of the Contingent Payment Rights is treated as part of an “open transaction” (as discussed below), the U.S. federal income tax consequences of the Mergers to U.S. Holders of Kineta Common Stock will be as follows:

| • |     | generally, capital gain will be recognized by a U.S. holder of Kineta Common Stock equal to the lesser of                                                                                                                                       
 (i) the amount of the cash (if any) received by such U.S. holder at the closing of the Mergers, and (ii) the difference, if any, between (x) the aggregate fair market value (as of the closing of the Mergers) of the aggregate Merger         
 Consideration received by such U.S. holder (not counting the Contingent Payment Rights) and (y) such holder’s adjusted tax basis in the Kineta Common Stock surrendered in the exchange. Such gain would be long-term capital gain if such U.S. 
 holder’s holding period for such shares of Kineta Common Stock is more than one year as of the closing date of the Mergers; unless the cash or property other than TuHURA stock received in the Mergers has the effect of a dividend under the  
 provisions of Section 302 and 356 of the Code, in which case the gain will be treated as dividend income to the extent of the holder’s ratable share of any earnings and profits, as calculated for U.S. federal income tax purposes. If a U.S. 
 holder acquired different blocks of Kineta Common Stock at different times or at different prices, such U.S. holder must determine its adjusted tax basis and holding period separately with respect to each block of Kineta Common Stock.      |

| • |     | generally, no loss will be recognized by a U.S. holder as a result of exchanging its Kineta Common Stock for the 
 Merger Consideration pursuant to the Mergers;                                                                    |

| • |     | the initial tax basis of the TuHURA Common Stock that a U.S. holder receives pursuant to the Mergers will                                                                                                                                              
 generally equal the aggregate adjusted tax basis in the shares of the Kineta Common Stock surrendered in exchange therefor
