 goodwill. TuHURA was determined to be the “accounting acquirer” in the Mergers for financial reporting purposes with Kineta being the “accounting acquiree” for financial reporting purposes. The determination of the Mergers being accounted for as business combination, and for TuHURA being the accounting acquirer is based primarily on evaluation of the following facts and circumstances:

| • |     | TuHURA securityholders are expected to own approximately 92.7% of the combined TuHURA Common Stock outstanding                                                                                                                                    
 immediately following the Effective Time when all former Kineta shareholders are issued their pro rata share of the maximum 3,998,051 shares of TuHURA common stock to be issued (currently estimated to be 3,868,635 shares based on anticipated 
 purchase price adjustments to the Initial Share Consideration) as the share component of the consideration transferred in accordance with the amended Merger Agreement,                                                                           |

| • |     | The TuHURA Board of Directors will remain the same after the Mergers, |

| • |     | TuHURA’s current senior management will remain the same after the Mergers, and |

| • |     | Operations of TuHURA will comprise the majority of the continuing operations of TuHURA after the Mergers. |
